Description

本発明は、目地カバー部材のカバー体に関し、詳しくは、建物躯体の外壁板同士の繋ぎ目に形成された目地の補修に用いる目地カバー部材のカバー体に関する。 The present invention relates to a cover body of a joint cover member, and more particularly to a cover body of a joint cover member used for repairing joints formed at joints between outer wall plates of a building frame.

例えば、住宅用の建物の外壁には、その意匠性を高めるため、各種のサイディング等の外壁板が、釘等を用いて建物躯体に固定されている。外壁板の固定構造としては、図１１に示すように、胴縁材１０１に固定したハット型断面の金具１０２（以下、「ハットジョイナー」という）の凸部１０３を挟んで、外壁板１０４の端部同士を対向させて、複数の外壁板を連続状に取り付ける構造が知られている。この場合、ハットジョイナーの凸部１０３と外壁板１０４の端部との隙間（目地）には、ゴム状の目地材１０５が充填されている（例えば、特許文献１を参照）。この目地に充填する目地材５は、一定の弾力性があり、気温変化による外壁板１０４の伸縮に追従することができる。そのため、外壁板１０４の目地から雨水等が浸入するのを防止することができる。 For example, on the outer wall of a residential building, outer wall boards such as various sidings are fixed to the building frame using nails or the like in order to enhance the design. As a fixing structure of the outer wall plate, as shown in FIG. 11, the end of the outer wall plate 104 sandwiches the convex portion 103 of the metal fitting 102 (hereinafter, referred to as “hat joiner”) having a hat-shaped cross section fixed to the furring strip 101. A structure is known in which a plurality of outer wall plates are continuously attached by facing each other. In this case, the gap (joint) between the convex portion 103 of the hat joiner and the end portion of the outer wall plate 104 is filled with the rubber-like joint material 105 (see, for example, Patent Document 1). The joint material 5 to be filled in the joint has a certain elasticity and can follow the expansion and contraction of the outer wall plate 104 due to the change in temperature. Therefore, it is possible to prevent rainwater or the like from entering through the joints of the outer wall plate 104.

しかしながら、一般に、目地材は、ゴム系部材であって、紫外線や温度変化等の影響を受けて劣化しやすい。そのため、ある程度の年月を経て、目地材が劣化して弾力性が低下すると、目地材に割れや剥がれ等が生じることがある。目地材に割れ、剥がれ等が生じた場合には、通常、古い目地材を剥がして新しい目地材に交換するという目地の補修が行われている。 However, in general, the joint material is a rubber-based member and is easily deteriorated by being affected by ultraviolet rays, temperature changes, and the like. Therefore, if the joint material deteriorates and its elasticity decreases after a certain period of time, the joint material may crack or peel off. When the joint material is cracked or peeled off, the joint is usually repaired by peeling off the old joint material and replacing it with a new joint material.

この目地の補修は、例えば、図１２に示すステップＴ１〜Ｔ７の手順に従って行われている。すなわち、先ず、古い目地材をカッターナイフ等で撤去する（ステップＴ１）。次に、マスキングテープを外壁板の端部周囲に貼ってから（ステップＴ２）、目地用の接着剤を外壁板の端面に塗る（ステップＴ３）。また、ハットジョイナーの凸部に目地材の接着防止テープを貼る（ステップＴ４）。その後、新しい目地材を外壁板の隙間に充填し（ステップＴ５）、目地材をヘラ等で押えて溝状の目地を形成する（ステップＴ６）。最後に、マスキングテープを剥がして、目地材が固まるのを待って（ステップＴ７）、目地の補修が完了する。 The repair of this joint is performed, for example, according to the procedure of steps T1 to T7 shown in FIG. That is, first, the old joint material is removed with a cutter knife or the like (step T1). Next, masking tape is applied around the end of the outer wall plate (step T2), and then the adhesive for joints is applied to the end face of the outer wall plate (step T3). In addition, an adhesive prevention tape for the joint material is attached to the convex portion of the hat joiner (step T4). After that, a new joint material is filled in the gap of the outer wall plate (step T5), and the joint material is pressed with a spatula or the like to form a groove-shaped joint (step T6). Finally, the masking tape is peeled off, and the joint material is waited to harden (step T7) to complete the repair of the joint.

上記目地の補修作業には、熟練の作業スキルが必要であると共に、多大な手間が掛かり、補修費用も高くなるという問題があった。また、古い目地材を新しい目地材に交換しても、目地材は、もともと劣化しやすいので、所定の年月（約１０年程度）が経過すれば、再度補修しなければならないという問題もあった。 The repair work of the above joints requires skillful work skills, requires a great deal of labor, and has a problem that the repair cost is high. In addition, even if the old joint material is replaced with a new joint material, the joint material is liable to deteriorate from the beginning, so there is a problem that the joint material must be repaired again after a predetermined period of time (about 10 years). It was.

本発明は、上記問題点を解決するためになされたものであり、その目的は、簡単に目地を補修できて、耐久性の高い目地カバー部材のカバー体を提供することである。 The present invention has been made to solve the above problems, and an object of the present invention is to provide a cover body of a joint cover member which can easily repair joints and has high durability.

（目地カバー部材の構成）
図１〜図４に示すように、本実施形態に係る第1実施例の目地カバー部材５は、建物躯体１の胴縁材１１に固定されたハットジョイナー２の凸部２１と、当該凸部２１を挟んで端部３１同士を対向させて胴縁材１１に固定された外壁板３の端部３１との隙間に、ゴム状の目地材４１が充填されている目地４の補修に用いる目地カバー部材である。外壁板３は、例えば、窯業系サイディング等が該当する。ここでは、外壁板３は、長方形の板状に形成され、また、長辺が上下方向に延設されている。目地カバー部材５は、外壁板３の長辺に沿って取り付けられている。 (Structure of joint cover member)
As shown in FIGS. 1 to 4, the joint cover member 5 of the first embodiment according to the present embodiment has a convex portion 21 of the hat joiner 2 fixed to the furring strip 11 of the building frame 1 and the convex portion. A joint used for repairing a joint 4 in which a rubber-like joint material 41 is filled in a gap between the ends 31 of the outer wall plate 3 fixed to the furring strip 11 with the ends 31 facing each other with the 21 in between. It is a cover member. The outer wall plate 3 corresponds to, for example, ceramic siding or the like. Here, the outer wall plate 3 is formed in a rectangular plate shape, and its long side extends in the vertical direction. The joint cover member 5 is attached along the long side of the outer wall plate 3.

また、目地カバー部材５には、外壁板３の端部外表面３１１にそれぞれ当接する一対の外接フランジ部５１１と、当該外接フランジ部５１１同士の間に形成され目地材４１と離間して対向する目地対向部５１２とを有するカバー体５１と、カバー体５１の裏面に接合され目地材４１の表面と外壁板３の端部３１とに当接する弾性体５２とを備えている。また、カバー体５１は、目地対向部５１２の外表面から挿入され凸部２１に係合されたネジ部材６を介して、ハットジョイナー２に締結されている。なお、カバー体５１は、例えば、防錆性能の高いアルミ亜鉛合金メッキ鋼板（通称、「ガルバリウム鋼板（登録商標）」と呼ぶ）で形成されていることが好ましい。カバー体５１の板厚は、例えば、０．３〜０．５ｍｍ程度が好ましい。ここでは、弾性体５２は、矩形状断面に形成されているが、目地材４１との当接面を蒲鉾状に形成してもよい。目地材４１は、円弧状に凹むことが多いからである。 Further, the joint cover member 5 is formed between a pair of external flange portions 511 that are in contact with the outer surface 311 of the end portion of the outer wall plate 3 and the external flange portions 511, and is separated from the joint material 41 and faces the joint material 41. A cover body 51 having a joint facing portion 512 and an elastic body 52 joined to the back surface of the cover body 51 and in contact with the front surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are provided. Further, the cover body 51 is fastened to the hat joiner 2 via a screw member 6 inserted from the outer surface of the joint facing portion 512 and engaged with the convex portion 21. The cover body 51 is preferably formed of, for example, an aluminum-zinc alloy-plated steel plate having high rust prevention performance (commonly referred to as "galvalume steel plate (registered trademark)"). The plate thickness of the cover body 51 is preferably, for example, about 0.3 to 0.5 mm. Here, the elastic body 52 is formed in a rectangular cross section, but the contact surface with the joint material 41 may be formed in a semi-cylindrical shape. This is because the joint material 41 is often recessed in an arc shape.

また、ネジ部材６には、頭部６１からネジ部６２の軸方向に形成された縦孔６３と、凸部２１の裏面側で縦孔６３と交差してネジ部６２の外表面まで貫通された横孔６４とを備え、また、ネジ部６２が凸部２１に係合された状態で、縦孔６３の頭部開口部６３１から注入された接着剤７が、横孔６４のネジ貫通部６４１からはみ出してネジ部６２と凸部２１とを連結していることが好ましい。ネジ部材６のネジ部６２とハットジョイナー２の凸部２１とを接着剤７を介して、より強固に連結することができ、温度変化等によって目地カバー部材５を締結するネジ部材６が緩むのを抑制でき、目地カバー部材５のシール性をより一層高めることができるからである。なお、ネジ部材６は、ネジ部６２がハットジョイナー２の凸部２１には係合するが、建物躯体１には挿入されない程度のもの（長さ）を選定する。また、頭部６１には、ドライバー溝が形成されている。 Further, the screw member 6 is penetrated from the head portion 61 to the outer surface of the screw portion 62 by intersecting the vertical hole 63 formed in the axial direction of the screw portion 62 and the vertical hole 63 on the back surface side of the convex portion 21. The adhesive 7 injected from the head opening 631 of the vertical hole 63 in a state where the horizontal hole 64 is provided and the screw portion 62 is engaged with the convex portion 21 is the screw penetrating portion of the horizontal hole 64. It is preferable that the screw portion 62 and the convex portion 21 are connected so as to protrude from 641. The screw portion 62 of the screw member 6 and the convex portion 21 of the hat joiner 2 can be more firmly connected via the adhesive 7, and the screw member 6 for fastening the joint cover member 5 is loosened due to a temperature change or the like. This is because the sealing property of the joint cover member 5 can be further improved. The screw member 6 is selected so that the screw portion 62 engages with the convex portion 21 of the hat joiner 2 but is not inserted into the building skeleton 1. Further, a driver groove is formed in the head 61.

また、弾性体５２は、気泡が半連続的に分散されたゴム系のスポンジ部材５２Ｓであることが好ましい。スポンジ部材５２Ｓは、例えば、ＥＰＤＭ（エチレン・プロピレン・ジエンゴム）を主成分とした軟質半連続発泡ゴムであって、その片面にアクリル系粘着剤が形成されているものが、より好ましい。スポンジ部材５２Ｓは、カバー体５１と外壁板３との隙間から浸入した雨水を吸水することができ、また、目地材４１の表面と外壁板３の端部３１とに当接する際、スポンジ面が柔軟に変形して目地材４１の表面と外壁板３の端部３１とに密着しやすいからである。また、スポンジ部材５２Ｓは、気泡に含まれた空気層によって、目地材４１に対する断熱効果を高めることができ、目地材４１の劣化の進行を遅らせることもできるからである。なお、スポンジ部材５２Ｓにおける気泡の大きさは、必ずしも均一でなくともよい。 Further, the elastic body 52 is preferably a rubber-based sponge member 52S in which bubbles are semi-continuously dispersed. The sponge member 52S is, for example, a soft semi-continuous foam rubber containing EPDM (ethylene, propylene, diene rubber) as a main component, and one having an acrylic pressure-sensitive adhesive formed on one side thereof is more preferable. The sponge member 52S can absorb rainwater that has entered through the gap between the cover body 51 and the outer wall plate 3, and when the surface of the joint material 41 comes into contact with the end portion 31 of the outer wall plate 3, the sponge surface is exposed. This is because it is flexibly deformed and easily adheres to the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Further, the sponge member 52S can enhance the heat insulating effect on the joint material 41 by the air layer contained in the air bubbles, and can delay the progress of deterioration of the joint material 41. The size of the bubbles in the sponge member 52S does not necessarily have to be uniform.

また、カバー体５１において、外接フランジ部５１１と目地対向部５１２とが、外壁板３の表裏方向に起立する縦壁部５１３によって連結されていることが好ましい。外壁板３の端部外表面３１１に対して平行に形成された外接フランジ部５１１と目地対向部５１２とを、端部外表面３１１に対して垂直に形成された縦壁部５１３によって連結することによって、カバー体５１の断面係数を高め、カバー体５１の長手方向における反りや捻じれ等に対する剛性を高めることができるからである。そのため、目地カバー部材５のシール性を高めると共に、カバー体５１の軽量化が可能となり、また、ネジ部材６の本数を低減できる。なお、外接フランジ部５１１には、外壁板３の端部外表面３１１に当接する外縁部を内方に折り曲げて重ね合わせるハゼ折り部５１１Ｈが形成されている。ハゼ折り部５１１Ｈを形成することによって、防錆性能と安全性能を高めることができる。 Further, in the cover body 51, it is preferable that the circumscribed flange portion 511 and the joint facing portion 512 are connected by a vertical wall portion 513 that stands up in the front and back directions of the outer wall plate 3. The outer flange portion 511 formed parallel to the end outer surface 311 of the outer wall plate 3 and the joint facing portion 512 are connected by a vertical wall portion 513 formed perpendicular to the end outer surface 311. This is because the cross-sectional coefficient of the cover body 51 can be increased, and the rigidity of the cover body 51 against warpage, twisting, etc. in the longitudinal direction can be increased. Therefore, the sealing performance of the joint cover member 5 can be improved, the weight of the cover body 51 can be reduced, and the number of screw members 6 can be reduced. The circumscribed flange portion 511 is formed with a goby folded portion 511H in which an outer edge portion abutting on the outer surface 311 of the end portion of the outer wall plate 3 is bent inward and overlapped. By forming the goby folding portion 511H, rust prevention performance and safety performance can be improved.

ここでは、目地対向部５１２は、目地４の溝幅４Ｈと略同一の幅で形成され、外接フランジ部５１１から外壁板３の表方向に起立する一対の縦壁部５１３と連結されている。これによって、カバー体５１の剛性をより一層向上させることができ、ネジ部材６によってカバー体５１をハットジョイナー２に締結するときの目地対向部５１２の変形等をより一層回避し得る。また、弾性体５２であるスポンジ部材５２Ｓは、縦壁部５１３同士の隙間に嵌装され、目地対向部５１２の裏面に接合されている。これによって、ネジ部材６によってカバー体５１をハットジョイナー２に締結したとき、弾性体５２（スポンジ部材５２Ｓ）を圧縮させて目地材４１の表面と外壁板３の端部３１とにより一層密着させてシール性を高めることができる。 Here, the joint facing portion 512 is formed to have substantially the same width as the groove width 4H of the joint 4, and is connected to a pair of vertical wall portions 513 that stand up from the circumscribed flange portion 511 in the front direction of the outer wall plate 3. As a result, the rigidity of the cover body 51 can be further improved, and deformation of the joint facing portion 512 when the cover body 51 is fastened to the hat joiner 2 by the screw member 6 can be further avoided. Further, the sponge member 52S, which is an elastic body 52, is fitted in the gap between the vertical wall portions 513 and is joined to the back surface of the joint facing portion 512. As a result, when the cover body 51 is fastened to the hat joiner 2 by the screw member 6, the elastic body 52 (sponge member 52S) is compressed so that the surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are further brought into close contact with each other. The sealing property can be improved.

図３、図５、図６に示すように、はじめに、カバー体形成工程Ｓ１において、所定の幅及び長さに切断した鋼板を曲げ加工して、目地カバー部材５のカバー体５１を形成する。カバー体５１は、ハゼ折り部５１１Ｈと外接フランジ部５１１と縦壁部５１３と目地対向部５１２とを所定のハット断面に曲げ加工した後に、ハゼ折り部５１１Ｈのみを外接フランジ部５１１の裏面側へ重ね合わせるようにヘミング曲げ加工して形成する。その後、目地対向部５１２には、ネジ部材６の締結位置に対応してネジ下孔５１２Ｐを形成する。 (Joint repair method using joint cover member)
As shown in FIGS. 3, 5, and 6, first, in the cover body forming step S1, the steel plate cut to a predetermined width and length is bent to form the cover body 51 of the joint cover member 5. In the cover body 51, after bending the goby folding portion 511H, the circumscribed flange portion 511, the vertical wall portion 513, and the joint facing portion 512 into a predetermined hat cross section, only the goby folding portion 511H is moved to the back surface side of the circumscribed flange portion 511. It is formed by hemming bending so as to overlap. After that, a screw pilot hole 512P is formed in the joint facing portion 512 corresponding to the fastening position of the screw member 6.

次に、弾性体形成工程Ｓ２において、所定の幅に形成された弾性体５２（スポンジ部材５２Ｓ）を所定の長さに切断する。弾性体５２（スポンジ部材５２Ｓ）の厚さは、外壁板３の端部外表面３１１に対する目地材４１の引け具合によって選定する。また、弾性体５２（スポンジ部材５２Ｓ）には、ネジ部材６の締結位置（目地対向部５１２に形成されたネジ下孔５１２Ｐ）に対応して切欠き部５２１を形成する。切欠き部５２１は、ネジ部６２のネジ溝による巻き込みを回避できるように、Ｖ字状又はＵ字状に形成することが好ましい。 Next, in the elastic body forming step S2, the elastic body 52 (sponge member 52S) formed to have a predetermined width is cut into a predetermined length. The thickness of the elastic body 52 (sponge member 52S) is selected according to the degree of shrinkage of the joint material 41 with respect to the end outer surface 311 of the outer wall plate 3. Further, the elastic body 52 (sponge member 52S) is formed with a notch portion 521 corresponding to the fastening position of the screw member 6 (screw pilot hole 512P formed in the joint facing portion 512). The notch portion 521 is preferably formed in a V shape or a U shape so as to avoid being caught by the screw groove of the screw portion 62.

次に、弾性体接合工程Ｓ３において、弾性体５２（スポンジ部材５２Ｓ）をカバー体５１の裏面に接合する。ここでは、弾性体５２（スポンジ部材５２Ｓ）は、ＥＰＤＭ（エチレン・プロピレン・ジエンゴム）を主成分とした軟質半連続発泡ゴムであって、その片面にアクリル系粘着剤が形成されているので、目地対向部５１２の裏面に、アクリル系粘着剤５２２を介して貼着する。また、弾性体５２（スポンジ部材５２Ｓ）は、カバー体５１の目地対向部５１２に貼着した状態で、目地材４１及び外壁板３に当接する当接面５２３が、外接フランジ部５１１より外方へ突出している。 Next, in the elastic body joining step S3, the elastic body 52 (sponge member 52S) is joined to the back surface of the cover body 51. Here, the elastic body 52 (sponge member 52S) is a soft semi-continuous foam rubber containing EPDM (ethylene, propylene, diene rubber) as a main component, and an acrylic adhesive is formed on one side of the elastic body 52 (sponge member 52S). It is attached to the back surface of the facing portion 512 via an acrylic adhesive 522. Further, in the state where the elastic body 52 (sponge member 52S) is attached to the joint facing portion 512 of the cover body 51, the contact surface 523 that comes into contact with the joint material 41 and the outer wall plate 3 is outward from the circumscribed flange portion 511. It protrudes to.

次に、カバー締結工程Ｓ４において、弾性体５２（スポンジ部材５２Ｓ）を接合したカバー体５１をネジ部材６を介してハットジョイナー２の凸部２１に係合する。ネジ部材６は、頭部６１からネジ部６２の軸方向に形成された縦孔６３と、凸部２１の裏面側で縦孔６３と交差してネジ部６２の外表面まで貫通された横孔６４とを備えたネジを使用し、目地対向部５１２に形成したネジ下孔５１２Ｐから挿入する。また、ネジ部６２がハットジョイナー２の凸部２１に係合された状態で、縦孔６３の頭部開口部６３１から接着剤７を注入する。接着剤７は、横孔６４のネジ貫通部６４１からはみ出して、ネジ部６２と凸部２１とを連結した状態で固化する。 Next, in the cover fastening step S4, the cover body 51 to which the elastic body 52 (sponge member 52S) is joined is engaged with the convex portion 21 of the hat joiner 2 via the screw member 6. The screw member 6 has a vertical hole 63 formed in the axial direction of the screw portion 62 from the head portion 61 and a horizontal hole that intersects the vertical hole 63 on the back surface side of the convex portion 21 and penetrates to the outer surface of the screw portion 62. Using a screw provided with 64, the screw is inserted through the screw pilot hole 512P formed in the joint facing portion 512. Further, the adhesive 7 is injected from the head opening 631 of the vertical hole 63 in a state where the screw portion 62 is engaged with the convex portion 21 of the hat joiner 2. The adhesive 7 protrudes from the screw penetrating portion 641 of the lateral hole 64 and solidifies in a state where the screw portion 62 and the convex portion 21 are connected.

以上の工程によって、目地材４１が劣化した箇所において、劣化した目地材４１を新しい目地材に取り換えることなく、ハットジョイナー２に対してネジ部材６によって目地カバー部材５を取り付けるだけで、目地４の補修が可能となる。 In the place where the joint material 41 has deteriorated by the above steps, the joint cover member 5 is simply attached to the hat joiner 2 by the screw member 6 without replacing the deteriorated joint material 41 with a new joint material. It can be repaired.

＜第２実施例の目地カバー部材＞
本実施形態に係る第２実施例の目地カバー部材について、図７を用いて説明する。図７に、本実施形態に係る第２実施例の目地カバー部材の取付け前後を表す断面図であって、（Ａ）は取付前の目地カバー部材の断面図を示し、（Ｂ）は取付後の目地カバー部材と外壁板の断面図を示す。ここでは、第２実施例の目地カバー部材について、第１実施例との共通点については、共通の符号を付して、その説明は原則として割愛し、第１実施例との相違点を中心に説明する。また、第２実施例の目地カバー部材を用いた目地補修方法は、前述した第１実施例の目地カバー部材を用いた目地補修方法と共通しているので、その説明は省略する。 <Joint cover member of the second embodiment>
The joint cover member of the second embodiment according to the present embodiment will be described with reference to FIG. 7. 7A and 7B are cross-sectional views showing before and after mounting of the joint cover member of the second embodiment according to the present embodiment, FIG. 7A shows a cross-sectional view of the joint cover member before mounting, and FIG. 7B shows a cross-sectional view after mounting. The cross-sectional view of the joint cover member and the outer wall plate is shown. Here, regarding the joint cover member of the second embodiment, common reference numerals are given to the common points with the first embodiment, and the explanation thereof is omitted in principle, focusing on the differences from the first embodiment. Explain to. Further, since the joint repair method using the joint cover member of the second embodiment is common to the joint repair method using the joint cover member of the first embodiment described above, the description thereof will be omitted.

（目地カバー部材の構成）
図７に示すように、本実施形態に係る第２実施例の目地カバー部材５Ｂは、建物躯体１の胴縁材１１に固定されたハットジョイナー２の凸部２１と、当該凸部２１を挟んで端部３１同士を対向させて胴縁材１１に固定された外壁板３の端部３１との隙間に、ゴム状の目地材４１が充填されている目地４の補修に用いる目地カバー部材であって、目地カバー部材５Ｂには、外壁板３の端部外表面３１１にそれぞれ当接する一対の外接フランジ部５１１と、当該外接フランジ部５１１同士の間に形成され目地材４１と離間して対向する目地対向部５１２とを有するカバー体５１と、カバー体５１の裏面に接合され目地材４１の表面と外壁板３の端部３１とに当接する弾性体５２Ｂとを備えている。また、カバー体５１は、目地対向部５１２の外表面から挿入され凸部２１に係合されたネジ部材６を介して、ハットジョイナー２に締結されている。また、目地対向部５１２は、目地４の溝幅４Ｈと略同一の幅で形成され、外接フランジ部５１１から外壁板３の表方向に起立する一対の縦壁部５１３と連結されている。以上の構成は、基本的に第１実施例と共通する。 (Structure of joint cover member)
As shown in FIG. 7, the joint cover member 5B of the second embodiment according to the present embodiment sandwiches the convex portion 21 of the hat joiner 2 fixed to the furring strip 11 of the building frame 1 and the convex portion 21. A joint cover member used for repairing a joint 4 in which a rubber-like joint material 41 is filled in a gap between the ends 31 of the outer wall plate 3 fixed to the furring strip 11 with the ends 31 facing each other. The joint cover member 5B has a pair of extrinsic flange portions 511 that are in contact with the outer surface 311 of the end portion of the outer wall plate 3, and are formed between the extrinsic flange portions 511 and face each other at a distance from the joint material 41. A cover body 51 having a joint facing portion 512 and an elastic body 52B joined to the back surface of the cover body 51 and in contact with the front surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are provided. Further, the cover body 51 is fastened to the hat joiner 2 via a screw member 6 inserted from the outer surface of the joint facing portion 512 and engaged with the convex portion 21. Further, the joint facing portion 512 is formed with substantially the same width as the groove width 4H of the joint 4, and is connected to a pair of vertical wall portions 513 that stand up from the circumscribed flange portion 511 in the front direction of the outer wall plate 3. The above configuration is basically the same as that of the first embodiment.

しかし、第２実施例では、弾性体５２Ｂは、縦壁部５１３同士の隙間を跨いで外接フランジ部５１１の裏面に接合されている点が、第１実施例と相違する。すなわち、第２実施例では、弾性体５２Ｂの幅を広く形成し、縦壁部５１３同士の隙間に空間が形成されている。上記構成によって、ネジ部材６によってカバー体５１をハットジョイナー２に締結したとき、弾性体５２Ｂを外接フランジ部５１１が圧縮させて目地材４１の表面と外壁板３の端部３１とに密着させてシール性を高めると共に、目地対向部５１２と弾性体５２Ｂとの間に空間を形成して、断熱効果を高めることができる。 However, in the second embodiment, the elastic body 52B is different from the first embodiment in that the elastic body 52B is joined to the back surface of the circumscribed flange portion 511 so as to straddle the gap between the vertical wall portions 513. That is, in the second embodiment, the elastic body 52B is formed to have a wide width, and a space is formed in the gap between the vertical wall portions 513. According to the above configuration, when the cover body 51 is fastened to the hat joiner 2 by the screw member 6, the elastic body 52B is compressed by the external flange portion 511 to be brought into close contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. In addition to enhancing the sealing property, a space can be formed between the joint facing portion 512 and the elastic body 52B to enhance the heat insulating effect.

なお、弾性体５２Ｂは、気泡が半連続的に分散されたゴム系のスポンジ部材５２ＳＢであることが好ましい。スポンジ部材５２ＳＢは、カバー体５１と外壁板３との隙間から浸入した雨水を吸水することができ、また、ネジ部材６によってカバー体５１をハットジョイナー２に締結したとき、スポンジ部材５２ＳＢが外接フランジ部５１１によって圧縮されやすく、外接フランジ部５１１と外壁板３の端部外表面３１１との間に隙間が生じにくいからである。また、スポンジ部材５２ＳＢは、目地材４１の表面と外壁板３の端部３１とに当接する際、スポンジ面が柔軟に変形して目地材４１の表面と外壁板３の端部３１とに密着しやすいからである。 The elastic body 52B is preferably a rubber-based sponge member 52SB in which bubbles are semi-continuously dispersed. The sponge member 52SB can absorb rainwater that has entered through the gap between the cover body 51 and the outer wall plate 3, and when the cover body 51 is fastened to the hat joiner 2 by the screw member 6, the sponge member 52SB is attached to the circumscribed flange. This is because it is easily compressed by the portion 511, and a gap is unlikely to occur between the circumscribed flange portion 511 and the end outer surface 311 of the outer wall plate 3. Further, when the sponge member 52SB comes into contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3, the sponge surface flexibly deforms and adheres to the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Because it is easy to do.

＜第３実施例の目地カバー部材＞
本実施形態に係る第３実施例の目地カバー部材について、図８を用いて説明する。図８に、本実施形態に係る第３実施例の目地カバー部材の取付け前後を表す断面図であって、（Ａ）は取付前の目地カバー部材の断面図を示し、（Ｂ）は取付後の目地カバー部材と外壁板の断面図を示す。ここでは、第３実施例の目地カバー部材について、第１実施例との共通点については、共通の符号を付して、その説明は原則として割愛し、第１実施例との相違点を中心に説明する。また、第３実施例の目地カバー部材を用いた目地補修方法は、前述した第１実施例の目地カバー部材を用いた目地補修方法と共通しているので、その説明は省略する。 <Joint cover member of the third embodiment>
The joint cover member of the third embodiment according to the present embodiment will be described with reference to FIG. 8A and 8B are cross-sectional views showing before and after mounting of the joint cover member of the third embodiment according to the present embodiment, in which FIG. 8A shows a cross-sectional view of the joint cover member before mounting, and FIG. 8B shows a cross-sectional view after mounting. The cross-sectional view of the joint cover member and the outer wall plate is shown. Here, regarding the joint cover member of the third embodiment, common reference numerals are given to the common points with the first embodiment, and the explanation thereof is omitted in principle, focusing on the differences from the first embodiment. Explain to. Further, since the joint repair method using the joint cover member of the third embodiment is common to the joint repair method using the joint cover member of the first embodiment described above, the description thereof will be omitted.

（目地カバー部材の構成）
図８に示すように、本実施形態に係る第３実施例の目地カバー部材５Ｃは、建物躯体１の胴縁材１１に固定されたハットジョイナー２の凸部２１と、当該凸部２１を挟んで端部３１同士を対向させて胴縁材１１に固定された外壁板３の端部３１との隙間に、ゴム状の目地材４１が充填されている目地４の補修に用いる目地カバー部材であって、目地カバー部材５Ｃには、外壁板３の端部外表面３１１にそれぞれ当接する一対の外接フランジ部５１１Ｃと、当該外接フランジ部５１１Ｃ同士の間に形成され目地材４１と離間して対向する目地対向部５１２Ｃとを有するカバー体５１Ｃと、カバー体５１Ｃの裏面に接合され目地材４１の表面と外壁板３の端部３１とに当接する弾性体５２とを備えている。また、カバー体５１Ｃは、目地対向部５１２の外表面から挿入され凸部２１に係合されたネジ部材６を介して、ハットジョイナー２に締結されている。以上の構成は、基本的に第１実施例と共通する。 (Structure of joint cover member)
As shown in FIG. 8, the joint cover member 5C of the third embodiment according to the present embodiment sandwiches the convex portion 21 of the hat joiner 2 fixed to the furring strip 11 of the building frame 1 and the convex portion 21. A joint cover member used for repairing a joint 4 in which a rubber-like joint material 41 is filled in a gap between the ends 31 of the outer wall plate 3 fixed to the furring strip 11 with the ends 31 facing each other. The joint cover member 5C is formed between a pair of extrinsic flange portions 511C that are in contact with the outer surface 311 of the end portion of the outer wall plate 3 and the extrinsic flange portions 511C, and are separated from the joint material 41 and face each other. A cover body 51C having a joint facing portion 512C and an elastic body 52 joined to the back surface of the cover body 51C and in contact with the front surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are provided. Further, the cover body 51C is fastened to the hat joiner 2 via a screw member 6 inserted from the outer surface of the joint facing portion 512 and engaged with the convex portion 21. The above configuration is basically the same as that of the first embodiment.

しかし、第３実施例では、目地対向部５１２Ｃは、目地４の溝幅４Ｈと略同一の幅で形成され、外壁板３の表方向に向けて凸湾曲状に形成された外接フランジ部５１１Ｃと連結されている点が、第１実施例と相違する。すなわち、第３実施例では、外接フランジ部５１１Ｃが、外壁板３の端部外表面３１１に当接するハゼ折り部５１１ＨＣから外壁板３の表方向に向けて凸湾曲状に形成されて目地対向部５１２Ｃと連結されている。目地対向部５１２Ｃの裏面には、目地幅４Ｈに形成された弾性体５２が接合されている。上記構成によって、ネジ部材６によってカバー体５１Ｃをハットジョイナー２に締結したとき、目地対向部５１２Ｃが弾性体５２を押圧して目地材４１の表面と外壁板３の端部３１とに密着させてシール性を高めると共に、外接フランジ部５１１Ｃと弾性体５２との間に空間を形成して、断熱効果を高めることができる。 However, in the third embodiment, the joint facing portion 512C is formed with substantially the same width as the groove width 4H of the joint 4, and is formed in a convex curved shape toward the front of the outer wall plate 3 with the circumscribed flange portion 511C. The point that they are connected is different from the first embodiment. That is, in the third embodiment, the circumscribed flange portion 511C is formed in a convex curved shape toward the front surface of the outer wall plate 3 from the goby folding portion 511HC that abuts on the outer surface 311 of the end portion of the outer wall plate 3, and the joint facing portion. It is connected to 512C. An elastic body 52 formed with a joint width of 4H is joined to the back surface of the joint facing portion 512C. According to the above configuration, when the cover body 51C is fastened to the hat joiner 2 by the screw member 6, the joint facing portion 512C presses the elastic body 52 so that the surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are brought into close contact with each other. In addition to improving the sealing property, a space can be formed between the external flange portion 511C and the elastic body 52 to enhance the heat insulating effect.

なお、弾性体５２は、気泡が半連続的に分散されたゴム系のスポンジ部材５２Ｓであることが好ましい。スポンジ部材５２Ｓは、カバー体５１Ｃと外壁板３との隙間から浸入した雨水を吸水することができ、また、ネジ部材６によってカバー体５１Ｃをハットジョイナー２に締結したとき、スポンジ部材５２Ｓが目地対向部５１２Ｃによって圧縮されやすく、外接フランジ部５１１Ｃと外壁板３の端部外表面３１１との間に隙間が生じにくいからである。また、スポンジ部材５２Ｓは、目地材４１の表面と外壁板３の端部３１とに当接する際、スポンジ面が柔軟に変形して目地材４１の表面と外壁板３の端部３１とに密着しやすいからである。 The elastic body 52 is preferably a rubber-based sponge member 52S in which bubbles are dispersed semi-continuously. The sponge member 52S can absorb rainwater that has entered through the gap between the cover body 51C and the outer wall plate 3, and when the cover body 51C is fastened to the hat joiner 2 by the screw member 6, the sponge member 52S faces the joint. This is because it is easily compressed by the portion 512C, and a gap is unlikely to occur between the outer flange portion 511C and the end outer surface 311 of the outer wall plate 3. Further, when the sponge member 52S comes into contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3, the sponge surface flexibly deforms and comes into close contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Because it is easy to do.

＜第４実施例の目地カバー部材＞
本実施形態に係る第４実施例の目地カバー部材について、図９を用いて説明する。図９に、本実施形態に係る第４実施例の目地カバー部材の取付け前後を表す断面図であって、（Ａ）は取付前の目地カバー部材の断面図を示し、（Ｂ）は取付後の目地カバー部材と外壁板の断面図を示す。ここでは、第４実施例の目地カバー部材について、第１実施例との共通点については、共通の符号を付して、その説明は原則として割愛し、第１実施例との相違点を中心に説明する。また、第４実施例の目地カバー部材を用いた目地補修方法は、前述した第１実施例の目地カバー部材を用いた目地補修方法と共通しているので、その説明は省略する。 <Joint cover member of the fourth embodiment>
The joint cover member of the fourth embodiment according to the present embodiment will be described with reference to FIG. 9A and 9B are cross-sectional views showing before and after mounting of the joint cover member of the fourth embodiment according to the present embodiment, in which FIG. 9A shows a cross-sectional view of the joint cover member before mounting, and FIG. 9B shows a cross-sectional view after mounting. The cross-sectional view of the joint cover member and the outer wall plate is shown. Here, regarding the joint cover member of the fourth embodiment, the common points with the first embodiment are given a common reference numeral, and the explanation thereof is omitted in principle, focusing on the differences from the first embodiment. Explain to. Further, since the joint repair method using the joint cover member of the fourth embodiment is common to the joint repair method using the joint cover member of the first embodiment described above, the description thereof will be omitted.

（目地カバー部材の構成）
図９に示すように、本実施形態に係る第４実施例の目地カバー部材５Ｄは、建物躯体１の胴縁材１１に固定されたハットジョイナー２の凸部２１と、当該凸部２１を挟んで端部３１同士を対向させて胴縁材１１に固定された外壁板３の端部３１との隙間に、ゴム状の目地材４１が充填されている目地４の補修に用いる目地カバー部材であって、目地カバー部材５Ｄには、隣接する外壁板３の端部外表面３１１にそれぞれ当接する一対の外接フランジ部５１１Ｄと、当該外接フランジ部５１１Ｄ同士の間に形成され目地材４１と離間して対向する目地対向部５１２Ｄとを有するカバー体５１Ｄと、カバー体５１Ｄの裏面に接合され目地材４１の表面と外壁板３の端部３１とに当接する弾性体５２とを備えている。また、カバー体５１Ｄは、目地対向部５１２Ｄの外表面から挿入され凸部２１に係合されたネジ部材６を介して、ハットジョイナー２に締結されている。以上の構成は、基本的に第１実施例と共通する。 (Structure of joint cover member)
As shown in FIG. 9, the joint cover member 5D of the fourth embodiment according to the present embodiment sandwiches the convex portion 21 of the hat joiner 2 fixed to the furring strip 11 of the building frame 1 and the convex portion 21. A joint cover member used for repairing a joint 4 in which a rubber-like joint material 41 is filled in a gap between the ends 31 of the outer wall plate 3 fixed to the furring strip 11 with the ends 31 facing each other. Therefore, the joint cover member 5D is formed between a pair of extrinsic flange portions 511D that come into contact with the end outer surface 311 of the adjacent outer wall plate 3 and the extrinsic flange portions 511D, and is separated from the joint material 41. It is provided with a cover body 51D having a joint facing portion 512D facing the joint, and an elastic body 52 joined to the back surface of the cover body 51D and in contact with the front surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Further, the cover body 51D is fastened to the hat joiner 2 via a screw member 6 inserted from the outer surface of the joint facing portion 512D and engaged with the convex portion 21. The above configuration is basically the same as that of the first embodiment.

しかし、第４実施例では、目地対向部５１２Ｄは、目地４の溝幅４Ｈと略同一の幅で形成され、外接フランジ部５１１Ｄから外壁板３の裏方向に起立する一対の縦壁部５１３Ｄと連結されている点と、外接フランジ部５１１Ｄは、外壁板３の端部外表面３１１に当接するハゼ折り部５１１ＨＤから外壁板３の表方向に向けて凸湾曲状に形成されている点が、第１実施例と相違する。すなわち、第４実施例では、外接フランジ部５１１Ｄがハゼ折り部５１１ＨＤから外壁板３の表方向に向けて凸湾曲状に形成され、目地対向部５１２Ｃが外接フランジ部５１１Ｄから外壁板３の裏方向に起立する一対の縦壁部５１３Ｄと連結されている。目地対向部５１２Ｄの裏面には、目地幅４Ｈに形成された弾性体５２が接合されている。上記構成によって、ネジ部材６によってカバー体５１Ｄをハットジョイナー２に締結したとき、目地対向部５１２Ｄが弾性体５２を押圧して目地材４１の表面と外壁板３の端部３１とに密着させてシール性を高めると共に、外接フランジ部５１１Ｄと弾性体５２との間に、より大きな空間を形成して、断熱効果をより一層高めることができる。また、ネジ部材６の頭部６１には、目地対向部５１２Ｄに当接する廻り止め部材８が装着されている。そのため、ネジ部材６は、一対の縦壁部５１３Ｄ同士の隙間に挿入され、緩み止め効果を有しつつ、外観上目立ちにくくさせることができる。 However, in the fourth embodiment, the joint facing portion 512D is formed with substantially the same width as the groove width 4H of the joint 4, and is formed with a pair of vertical wall portions 513D that stand up from the circumscribed flange portion 511D in the back direction of the outer wall plate 3. The point that the circumscribed flange portion 511D is formed in a convex curved shape from the haze folding portion 511HD that abuts on the end outer surface 311 of the outer wall plate 3 toward the front direction of the outer wall plate 3 It is different from the first embodiment. That is, in the fourth embodiment, the circumscribed flange portion 511D is formed in a convex curved shape from the goby folding portion 511HD toward the front surface of the outer wall plate 3, and the joint facing portion 512C is formed from the circumscribed flange portion 511D in the back direction of the outer wall plate 3. It is connected to a pair of vertical wall portions 513D that stand upright. An elastic body 52 formed with a joint width of 4H is joined to the back surface of the joint facing portion 512D. According to the above configuration, when the cover body 51D is fastened to the hat joiner 2 by the screw member 6, the joint facing portion 512D presses the elastic body 52 so that the surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are brought into close contact with each other. In addition to improving the sealing property, a larger space can be formed between the external flange portion 511D and the elastic body 52 to further enhance the heat insulating effect. Further, the head 61 of the screw member 6 is equipped with a detent member 8 that abuts on the joint facing portion 512D. Therefore, the screw member 6 is inserted into the gap between the pair of vertical wall portions 513D, and can be made inconspicuous in appearance while having a loosening prevention effect.

なお、弾性体５２は、気泡が半連続的に分散されたゴム系のスポンジ部材５２Ｓであることが好ましい。スポンジ部材５２Ｓは、カバー体５１Ｄと外壁板３との隙間から浸入した雨水を吸水することができ、また、ネジ部材６によってカバー体５１Ｄをハットジョイナー２に締結したとき、スポンジ部材５２Ｓが目地対向部５１２Ｄによって圧縮されやすく、外接フランジ部５１１Ｄと外壁板３の端部外表面３１１との間に隙間が生じにくいからである。また、スポンジ部材５２Ｓは、目地材４１の表面と外壁板３の端部３１とに当接する際、スポンジ面が柔軟に変形して目地材４１の表面と外壁板３の端部３１とに密着しやすいからである。 The elastic body 52 is preferably a rubber-based sponge member 52S in which bubbles are dispersed semi-continuously. The sponge member 52S can absorb rainwater that has entered through the gap between the cover body 51D and the outer wall plate 3, and when the cover body 51D is fastened to the hat joiner 2 by the screw member 6, the sponge member 52S faces the joint. This is because it is easily compressed by the portion 512D, and a gap is unlikely to occur between the outer flange portion 511D and the end outer surface 311 of the outer wall plate 3. Further, when the sponge member 52S comes into contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3, the sponge surface flexibly deforms and comes into close contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Because it is easy to do.

Here, regarding the joint cover member of the fifth embodiment, the common points with the first embodiment are designated by a common reference numeral, and the description thereof is omitted in principle, focusing on the differences from the first embodiment. Explain to. Further, since the joint repair method using the joint cover member of the fifth embodiment is common to the joint repair method using the joint cover member of the first embodiment described above, the description thereof will be omitted.

（目地カバー部材の構成）
図１０に示すように、本実施形態に係る第５実施例の目地カバー部材５Ｅは、建物躯体１の胴縁材１１に固定されたハットジョイナー２の凸部２１と、当該凸部２１を挟んで端部３１同士を対向させて胴縁材１１に固定された外壁板３の端部３１との隙間に、ゴム状の目地材４１が充填されている目地４の補修に用いる目地カバー部材であって、目地カバー部材５Ｅには、外壁板３、３Ｅの端部外表面３１１にそれぞれ当接する一対の外接フランジ部５１１Ｅと、当該外接フランジ部５１１Ｅ同士の間に形成され目地材４１と離間して対向する目地対向部５１２Ｅとを有するカバー体５１Ｅと、カバー体５１Ｅの裏面に接合され目地材４１の表面と外壁板３、３Ｅの端部３１、３１Ｅとに当接する弾性体５２Ｅとを備えている。また、カバー体５１Ｅは、目地対向部５１２Ｅの外表面から挿入され凸部２１に係合されたネジ部材６を介して、ハットジョイナー２に締結されている。また、カバー体５１Ｅにおいて、外接フランジ部５１１Ｅと目地対向部５１２Ｅとが、外壁板３の表裏方向に起立する縦壁部５１３Ｅによって連結されている。以上の構成は、基本的に第１実施例と共通する。 (Structure of joint cover member)
As shown in FIG. 10, the joint cover member 5E of the fifth embodiment according to the present embodiment sandwiches the convex portion 21 of the hat joiner 2 fixed to the furring strip 11 of the building frame 1 and the convex portion 21. A joint cover member used for repairing a joint 4 in which a rubber-like joint material 41 is filled in a gap between the ends 31 of the outer wall plate 3 fixed to the furring strip 11 with the ends 31 facing each other. Therefore, the joint cover member 5E is formed between a pair of extrinsic flange portions 511E that come into contact with the end outer surfaces 311 of the outer wall plates 3 and 3E and the extrinsic flange portions 511E, respectively, and is separated from the joint material 41. It is provided with a cover body 51E having joint facing portions 512E facing each other, and an elastic body 52E joined to the back surface of the cover body 51E and in contact with the front surface of the joint material 41 and the ends 31, 31E of the outer wall plates 3, 3E. ing. Further, the cover body 51E is fastened to the hat joiner 2 via a screw member 6 inserted from the outer surface of the joint facing portion 512E and engaged with the convex portion 21. Further, in the cover body 51E, the circumscribed flange portion 511E and the joint facing portion 512E are connected by a vertical wall portion 513E that stands up in the front and back directions of the outer wall plate 3. The above configuration is basically the same as that of the first embodiment.

しかし、第５実施例では、隣接する外壁板３の厚さが異なること、目地対向部５１２Ｅは、目地４の溝幅４Ｈと略同一の幅で形成され、薄い外壁板３に当接する一方の外接フランジ部５１１Ｅから厚い外壁板３の端部３１に沿って起立する縦壁部５１３Ｅと連結されている点が、第１実施例と相違する。すなわち、第５実施例では、カバー体５１Ｅが、薄い外壁板３に当接する一方の外接フランジ部５１１Ｅと、厚い外壁板３に当接する他方の外接フランジ部５１１Ｅとが、厚い外壁板３の端部３１に沿って起立する縦壁部５１３Ｅによって階段状に連結されている。なお、外接フランジ部５１１Ｅには、外壁板３の端部外表面３１１に当接する外縁部を内方に折り曲げて重ね合わせるハゼ折り部５１１ＨＥが形成されている。 However, in the fifth embodiment, the thickness of the adjacent outer wall plate 3 is different, and the joint facing portion 512E is formed with substantially the same width as the groove width 4H of the joint 4, and one of the joints abuts on the thin outer wall plate 3. The difference from the first embodiment is that the circumscribed flange portion 511E is connected to the vertical wall portion 513E that stands up along the end portion 31 of the thick outer wall plate 3. That is, in the fifth embodiment, one circumscribed flange portion 511E in which the cover body 51E abuts on the thin outer wall plate 3 and the other circumscribed flange portion 511E in contact with the thick outer wall plate 3 are the ends of the thick outer wall plate 3. It is connected in a stepped manner by a vertical wall portion 513E that stands up along the portion 31. The outer flange portion 511E is formed with a goby folded portion 511HE in which the outer edge portion abutting on the outer surface 311 of the end portion of the outer wall plate 3 is bent inward and overlapped.

また、目地対向部５１２Ｅの裏面には、目地幅４Ｈに形成された弾性体５２Ｅが接合されている。上記構成によって、ネジ部材６によってカバー体５１Ｅをハットジョイナー２に締結したとき、厚さの異なる外壁板３に外接フランジ部５１１Ｅが当接しつつ、目地対向部５１２Ｅが弾性体５２を押圧して目地材４１の表面と外壁板３の端部３１とに密着させてシール性を高めることができる。 Further, an elastic body 52E formed with a joint width of 4H is joined to the back surface of the joint facing portion 512E. According to the above configuration, when the cover body 51E is fastened to the hat joiner 2 by the screw member 6, the joint facing portion 512E presses the elastic body 52 while the circumscribed flange portion 511E abuts on the outer wall plates 3 having different thicknesses. The surface of the material 41 and the end portion 31 of the outer wall plate 3 can be brought into close contact with each other to improve the sealing property.

なお、弾性体５２Ｅは、気泡が半連続的に分散されたゴム系のスポンジ部材５２ＳＥであることが好ましい。スポンジ部材５２ＳＥは、カバー体５１Ｅと外壁板３との隙間から浸入した雨水を吸水することができ、また、ネジ部材６によってカバー体５１Ｅをハットジョイナー２に締結したとき、スポンジ部材５２ＳＥが目地対向部５１２Ｅによって圧縮されやすく、外接フランジ部５１１Ｅと外壁板３の端部外表面３１１との間に隙間が生じにくいからである。また、スポンジ部材５２ＳＥは、目地材４１の表面と外壁板３の端部３１とに当接する際、スポンジ面が柔軟に変形して目地材４１の表面と外壁板３の端部３１とに密着しやすいからである。 The elastic body 52E is preferably a rubber-based sponge member 52SE in which bubbles are semi-continuously dispersed. The sponge member 52SE can absorb rainwater that has entered through the gap between the cover body 51E and the outer wall plate 3, and when the cover body 51E is fastened to the hat joiner 2 by the screw member 6, the sponge member 52SE faces the joint. This is because it is easily compressed by the portion 512E, and a gap is unlikely to occur between the outer flange portion 511E and the end outer surface 311 of the outer wall plate 3. Further, when the sponge member 52SE comes into contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3, the sponge surface flexibly deforms and adheres to the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Because it is easy to do.

As described in detail above, according to the joint cover members 5, 5B, 5C, and 5E according to the present embodiment, the joint cover member has a pair of external flanges that each come into contact with the end outer surface 311 of the outer wall plate 3. Cover bodies 51, 51C, 51D, which have joint facing portions 512, 512C, 512D, 512E formed between the 511C, 511C, 511D, and 511E portions and facing each other at a distance from the joint material 41. 51E and elastic bodies 52, 52B, 52E joined to the back surface of the cover body and in contact with the front surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are provided, and the cover bodies 51, 51C, 51D, 51E are provided. , The cover bodies 51, 51C, 51D, because they are fastened to the hat joiner 2 via the screw member 6 inserted from the outer surface of the joint facing portions 512, 512C, 512D, and 512E and engaged with the convex portion 21. 51E was joined to the back surface of the cover bodies 51, 51C, 51D, 51E while covering the outer surface 311 at the end of the adjacent outer wall plate 3 and the joint material 41 filled in the joint 4 between the outer wall plates, respectively. The elastic bodies 52, 52B, 52E can be brought into close contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Therefore, the sealing properties of the joint cover members 5, 5B, 5C, and 5E with respect to the joint 4 of the outer wall plate 3 can be improved, and rainwater or the like can be effectively prevented from entering from the joint 4.

また、カバー体５１、５１Ｃ、５１Ｄ、５１Ｅは、目地対向部５１２、５１２Ｃ、５１２Ｄ、５１２Ｅの外表面から挿入され凸部２１に係合されたネジ部材６を介して、ハットジョイナー２に締結されているので、カバー体５１、５１Ｃ、５１Ｄ、５１Ｅの目地対向部５１２、５１２Ｃ、５１２Ｄ、５１２Ｅに対して外方からネジ部材６を締め付けることによって、簡単に、カバー体５１、５１Ｃ、５１Ｄ、５１Ｅの外接フランジ部５１１、５１１Ｃ、５１１Ｄ、５１１Ｅを外壁板３の端部外表面３１１に当接させ、且つ、カバー体５１、５１Ｃ、５１Ｄ、５１Ｅの裏面に接合された弾性体５２、５２Ｂ、５２Ｅを目地材４１の表面と外壁板３の端部３１とに密着させながら、目地カバー部材５、５Ｂ、５Ｃ、５Ｅをハットジョイナー２に取り付けることができる。そのため、目地材４１が劣化した箇所において、劣化した目地材４１を新しい目地材に取り換えることなく、ハットジョイナー２に対してネジ部材６によって目地カバー部材５、５Ｂ、５Ｃ、５Ｅを取り付けるだけで、目地４の補修が可能となる。また、カバー体５１、５１Ｃ、５１Ｄ、５１Ｅが劣化しやすい弾性体５２、５２Ｂ、５２Ｅを保護する構造であるので、目地カバー部材５、５Ｂ、５Ｃ、５Ｄ、５Ｅ自身の寿命を長期化することもできる。そのため、新しい目地材４１に交換する熟練の作業スキルを必要とせず、また、その手間を省けて補修費用の低減に寄与でき、さらに、目地カバー部材５、５Ｂ、５Ｃ、５Ｅの耐久性を高めることができる。 Further, the cover bodies 51, 51C, 51D and 51E are fastened to the hat joiner 2 via a screw member 6 inserted from the outer surface of the joint facing portions 512, 512C, 512D and 512E and engaged with the convex portion 21. Therefore, by tightening the screw member 6 from the outside to the joint facing portions 512, 512C, 512D, 512E of the cover bodies 51, 51C, 51D, 51E, the cover bodies 51, 51C, 51D, 51E can be easily used. 511, 511C, 511D, 511E are brought into contact with the outer surface 311 at the end of the outer wall plate 3, and the elastic bodies 52, 52B, 52E are joined to the back surfaces of the covers 51, 51C, 51D, 51E. The joint cover members 5, 5B, 5C, and 5E can be attached to the hat joiner 2 while keeping the joint material 41 in close contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Therefore, at the place where the joint material 41 has deteriorated, the joint cover members 5, 5B, 5C, and 5E are simply attached to the hat joiner 2 by the screw member 6 without replacing the deteriorated joint material 41 with a new joint material. The joint 4 can be repaired. Further, since the cover bodies 51, 51C, 51D and 51E have a structure that protects the elastic bodies 52, 52B and 52E that are easily deteriorated, the life of the joint cover members 5, 5B, 5C, 5D and 5E themselves can be extended. You can also. Therefore, it does not require skilled work skills to replace with a new joint material 41, and it is possible to save the trouble and contribute to the reduction of repair cost, and further improve the durability of the joint cover members 5, 5B, 5C and 5E. be able to.

よって、本実施形態によれば、古い目地材４１を交換することなく簡単に目地４を補修できて、耐久性の高い目地カバー部材５、５Ｂ、５Ｃ、５Ｅを提供することができる。 Therefore, according to the present embodiment, the joint 4 can be easily repaired without replacing the old joint material 41, and the joint cover members 5, 5B, 5C, and 5E having high durability can be provided.

また、本実施形態によれば、ネジ部材６には、頭部６１からネジ部６２の軸方向に形成された縦孔６３と、凸部２１の裏面側で縦孔６３と交差してネジ部６２の外表面まで貫通された横孔６４とを備え、また、ネジ部６２が凸部２１に係合された状態で、縦孔６３の頭部開口部６３１から注入された接着剤７が、横孔６４のネジ貫通部６４１からはみ出してネジ部６２と凸部２１とを連結しているので、ネジ部材６のネジ部６２とハットジョイナー２の凸部２１とを接着剤７を介して、より強固に連結することができる。そのため、温度変化等によって目地カバー部材５を締結するネジ部材６が緩むのを抑制でき、目地カバー部材５のシール性をより一層高めることができる。 Further, according to the present embodiment, in the screw member 6, a vertical hole 63 formed in the axial direction from the head portion 61 to the screw portion 62 and a screw portion intersecting the vertical hole 63 on the back surface side of the convex portion 21. The adhesive 7 injected from the head opening 631 of the vertical hole 63 is provided with the horizontal hole 64 penetrating to the outer surface of the 62, and the screw portion 62 is engaged with the convex portion 21. Since the screw portion 62 and the convex portion 21 are connected so as to protrude from the screw penetration portion 641 of the lateral hole 64, the screw portion 62 of the screw member 6 and the convex portion 21 of the hat joiner 2 are connected to each other via the adhesive 7. It can be connected more firmly. Therefore, it is possible to prevent the screw member 6 for fastening the joint cover member 5 from loosening due to a temperature change or the like, and it is possible to further improve the sealing property of the joint cover member 5.

また、本実施形態によれば、弾性体５２、５２Ｂ、５２Ｅは、気泡が半連続的に分散されたゴム系のスポンジ部材５２Ｓ、５２ＳＢ、５２ＳＥであるので、浸入した雨水の吸水性を高めることができる。また、カバー体５１、５１Ｃ、５１Ｄ、５１Ｅの裏面に接合されたスポンジ部材５２Ｓ、５２ＳＢ、５２ＳＥが、目地材４１の表面と外壁板３の端部３１とに当接する際、スポンジ面が柔軟に変形して目地材４１の表面と外壁板３の端部３１とに密着しやすい。そのため、カバー体５１、５１Ｃ、５１Ｄ、５１Ｅから多少の雨水が浸入しても、スポンジ部材５２Ｓ、５２ＳＢ、５２ＳＥが雨水を吸収しつつ、目地材４１の表面と外壁板３の端部３１とに密着した状態を維持することによって、建物躯体１内への雨水の浸入をより効果的に防止することができる。また、弾性体５２、５２Ｂ、５２Ｅは、気泡が半連続的に分散されたゴム系のスポンジ部材５２Ｓ、５２ＳＢ、５２ＳＥであるので、目地材４１に対する断熱効果を高めることができ、目地材４１の劣化の進行を遅らせることもできる。 Further, according to the present embodiment, the elastic bodies 52, 52B, 52E are rubber-based sponge members 52S, 52SB, 52SE in which bubbles are semi-continuously dispersed, so that the water absorption of the infiltrated rainwater is enhanced. Can be done. Further, when the sponge members 52S, 52SB, 52SE joined to the back surfaces of the cover bodies 51, 51C, 51D, 51E come into contact with the front surface of the joint material 41 and the end portion 31 of the outer wall plate 3, the sponge surface becomes flexible. It is easily deformed and easily adheres to the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Therefore, even if some rainwater infiltrates from the cover bodies 51, 51C, 51D, and 51E, the sponge members 52S, 52SB, and 52SE absorb the rainwater while forming the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. By maintaining the close contact state, it is possible to more effectively prevent rainwater from entering the building frame 1. Further, since the elastic bodies 52, 52B, 52E are rubber-based sponge members 52S, 52SB, 52SE in which air bubbles are dispersed semi-continuously, the heat insulating effect on the joint material 41 can be enhanced, and the joint material 41 can be enhanced. It is also possible to slow down the progress of deterioration.

また、本実施形態によれば、外接フランジ部５１１、５１１Ｄ、５１１Ｅと目地対向部５１２、５１２Ｄ、５１２Ｅとは、外壁板３の表裏方向に起立する縦壁部５１３、５１３Ｄ、５１３Ｅによって連結されているので、カバー体５１、５１Ｃ、５１Ｄ、５１Ｅの長手方向における反りや捻じれ等に対する剛性を高めることができる。そのため、目地カバー部材５、５Ｃ、５Ｄ、５Ｅのシール性を高めると共に、カバー体５１、５１Ｃ、５１Ｄ、５１Ｅの軽量化が可能となり、また、ネジ部材６の本数を低減できる。また、目地カバー部材５、５Ｃ、５Ｄ、５Ｅの取付作業の負担を軽減でき、その手間を省くこともできる。 Further, according to the present embodiment, the circumscribed flange portions 511, 511D, 511E and the joint facing portions 512, 512D, 512E are connected by vertical wall portions 513, 513D, 513E standing in the front and back directions of the outer wall plate 3. Therefore, it is possible to increase the rigidity of the cover bodies 51, 51C, 51D, 51E against warpage, twisting, etc. in the longitudinal direction. Therefore, the sealing performance of the joint cover members 5, 5C, 5D, and 5E can be improved, the weight of the cover bodies 51, 51C, 51D, and 51E can be reduced, and the number of screw members 6 can be reduced. In addition, the burden of mounting work of the joint cover members 5, 5C, 5D, and 5E can be reduced, and the labor can be saved.

また、本実施形態によれば、目地対向部５１２は、目地４の溝幅４Ｈと略同一の幅で形成され、外接フランジ部５１１から外壁板３の表方向に起立する一対の縦壁部５１３と連結されているので、カバー体５の剛性をより一層向上させることができ、ネジ部材６によってカバー体５１をハットジョイナー２に締結するときの変形等をより一層回避し得る。また、弾性体５２は、縦壁部５１３同士の隙間に嵌装され、目地対向部５１２の裏面に接合されているので、ネジ部材６によってカバー体５１をハットジョイナー２に締結したとき、弾性体５２を圧縮させて目地材４１の表面と外壁板３の端部３１とにより一層密着させてシール性を高めることができる。 Further, according to the present embodiment, the joint facing portion 512 is formed with substantially the same width as the groove width 4H of the joint 4, and is a pair of vertical wall portions 513 that stand up from the external flange portion 511 in the front direction of the outer wall plate 3. Since it is connected to the cover body 5, the rigidity of the cover body 5 can be further improved, and deformation and the like when the cover body 51 is fastened to the hat joiner 2 by the screw member 6 can be further avoided. Further, since the elastic body 52 is fitted in the gap between the vertical wall portions 513 and joined to the back surface of the joint facing portion 512, when the cover body 51 is fastened to the hat joiner 2 by the screw member 6, the elastic body 52 is an elastic body. The 52 can be compressed so that the surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are brought into closer contact with each other to improve the sealing property.

また、本実施形態によれば、目地対向部５１２は、目地４の溝幅４Ｈと略同一の幅で形成され、外接フランジ部５１１から外壁板３の表方向に起立する一対の縦壁部５１３と連結されているので、カバー体５１の剛性をより一層向上させることができ、ネジ部材６によってカバー体５１をハットジョイナー２に締結するときの変形等をより一層回避し得る。また、弾性体５２Ｂは、縦壁部５１３同士の隙間を跨いで外接フランジ部５１１の裏面に接合されているので、ネジ部材６によってカバー体５１をハットジョイナー２に締結したとき、外接フランジ部５１１が弾性体５２Ｂを圧縮させて目地材４１の表面と外壁板３の端部３１とに密着させてシール性を高めると共に、目地対向部５１２と弾性体５２Ｂとの間に空間を形成して、断熱効果を高めることができる。 Further, according to the present embodiment, the joint facing portion 512 is formed with substantially the same width as the groove width 4H of the joint 4, and is a pair of vertical wall portions 513 that stand up from the external flange portion 511 in the front direction of the outer wall plate 3. Therefore, the rigidity of the cover body 51 can be further improved, and deformation and the like when the cover body 51 is fastened to the hat joiner 2 by the screw member 6 can be further avoided. Further, since the elastic body 52B is joined to the back surface of the external flange portion 511 across the gap between the vertical wall portions 513, when the cover body 51 is fastened to the hat joiner 2 by the screw member 6, the external flange portion 511 Compresses the elastic body 52B into close contact between the surface of the joint material 41 and the end portion 31 of the outer wall plate 3 to improve the sealing property, and forms a space between the joint facing portion 512 and the elastic body 52B. The heat insulating effect can be enhanced.

また、目地カバー部材５を用いた目地補修方法に係る他の実施形態によれば、カバー体５１を形成するカバー体形成工程Ｓ１と、弾性体５２を形成する弾性体形成工程Ｓ２と、弾性体５２をカバー体５１の裏面に接合する弾性体接合工程Ｓ３と、弾性体５２を接合したカバー体５１をネジ部材６を介してハットジョイナー２の凸部２１に係合するカバー締結工程Ｓ４とを備え、弾性体形成工程Ｓ２では、弾性体５２に対してネジ部材６の締結位置に対応して切欠き部５２１を形成するので、ネジ部材６のネジ溝に弾性体５２が巻き込まれて、弾性体５２が変形し、弾性体５２と目地材４１の表面と外壁板３の端部３１との間に隙間が生じるのを回避できる。そのため、弾性体５２が、ネジ部材６の締結位置において、目地材４１の表面と外壁板３の端部３１とに対して隙間を生じることなく密着した状態を維持することによって、建物躯体１内への雨水の浸入をより効果的に防止することができる。 Further, according to another embodiment of the joint repair method using the joint cover member 5, the cover body forming step S1 for forming the cover body 51, the elastic body forming step S2 for forming the elastic body 52, and the elastic body An elastic body joining step S3 for joining the 52 to the back surface of the cover body 51 and a cover fastening step S4 for engaging the cover body 51 to which the elastic body 52 is joined with the convex portion 21 of the hat joiner 2 via the screw member 6. In the elastic body forming step S2, the notch portion 521 is formed with respect to the elastic body 52 corresponding to the fastening position of the screw member 6, so that the elastic body 52 is caught in the thread groove of the screw member 6 and is elastic. It is possible to prevent the body 52 from being deformed and a gap between the elastic body 52, the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Therefore, the elastic body 52 maintains a state of being in close contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3 at the fastening position of the screw member 6 without forming a gap, thereby causing the inside of the building frame 1 to be in close contact with each other. It is possible to more effectively prevent the ingress of rainwater into the area.
