Description
この発明は、板状外壁材とフレームとを備えた建物の外壁に関する。 The present invention relates to an outer wall of a building including a plate-like outer wall material and a frame.
従来から、板状外壁材である硬質木片セメント板とフレームとを備えた建物の外壁が知られている(特許文献1参照)。 Conventionally, the outer wall of the building provided with the hard wooden piece cement board which is a plate-shaped outer wall material, and a flame | frame is known (refer patent document 1).
かかる外壁は、硬質木片セメント板の裏面にフレームを接着剤とスクリュー釘とで接合している。 Such an outer wall has a frame joined to the back surface of the hard wood piece cement board with an adhesive and a screw nail.
このような外壁では、硬質木片セメント板の収縮、膨張などの変形時において、その硬質木片セメント板の裏面側は接着剤によってフレームに固定されていることにより、その裏面側の変形拘束が表面側の変形拘束より強くなっている。このため、硬質木片セメント板は、その収縮や膨張時に反り変形が発生するという問題があった。 In such an outer wall, when the hard wood cement board is deformed such as contraction or expansion, the back surface side of the hard wood cement board is fixed to the frame by an adhesive, so that the deformation restraint on the back surface side is restrained on the front surface side. It is stronger than the deformation constraint. For this reason, the hard wood piece cement board has a problem that warp deformation occurs during its contraction and expansion.
この発明の目的は、収縮や膨張時における板状外壁材の反り変形を抑制することのできる外壁を提供することにある。 An object of the present invention is to provide an outer wall capable of suppressing warp deformation of a plate-like outer wall material during contraction or expansion.
本発明は、板状外壁材と、この板状外壁材の裏面に接合されるフレームとを備えた外壁であって、前記板状外壁材の表面には、剛性の高いタイル状の複数の表面部材が接着剤で接合されており、前記板状外壁材と前記フレームとの接合部分のうち、所定の接合強度が要求される所定部分は接着剤とスクリュー釘とで接合されるとともに、前記所定部分以外の他の部分はスクリュー釘で接合されていることを特徴とする。 The present invention is an outer wall comprising a plate-like outer wall material and a frame joined to the back surface of the plate-like outer wall material, and the surface of the plate-like outer wall material has a plurality of highly rigid tile-shaped surfaces. The members are bonded with an adhesive, and among the bonded portions of the plate-like outer wall material and the frame, the predetermined portion requiring a predetermined bonding strength is bonded with an adhesive and a screw nail and the predetermined portion Other parts other than the part are joined by screw nails.
この発明によれば、収縮や膨張時における板状外壁材の反り変形が抑制される。 According to this invention, the warp deformation of the plate-like outer wall material during contraction or expansion is suppressed.
以下、この発明に係る外壁の実施の形態である実施例を図面に基づいて説明する。 Hereinafter, an example which is an embodiment of the outer wall concerning this invention is described based on a drawing.
図1は、この発明に係る外壁を有する建物ユニット1の概略構成を説明するための斜視図である。 FIG. 1 is a perspective view for explaining a schematic configuration of a building unit 1 having an outer wall according to the present invention.
この建物ユニット1は、横方向及び上下方向に複数連結させることでユニット建物(図示せず)を構成するものである。 This building unit 1 constitutes a unit building (not shown) by connecting a plurality of building units 1 in the horizontal direction and the vertical direction.
まず、構成から説明すると、この建物ユニット1は、四隅に配置される4本の柱2,…と、その上端間に横架される梁としての天井梁31,…と、その下端間に横架される梁としての床梁32,…とから構成される骨組構造体としてのラーメン構造体11を主たる構造部材としている。 First, in terms of configuration, this building unit 1 is composed of four columns 2,... Arranged at the four corners, a ceiling beam 31,. The main structural member is a rigid frame structure 11 as a frame structure composed of floor beams 32,.
この柱2と天井梁31及び床梁32とは、剛接合されているが、この剛接合はまったく柱2と梁31,32との角度が変わらないものに限定されるものではなく、現実的な構造物としての半剛接合で接合されているものも含むものである。 The column 2 and the ceiling beam 31 and the floor beam 32 are rigidly connected. However, the rigid connection is not limited to the one in which the angle between the column 2 and the beams 31 and 32 is not changed at all. Also included are those that are joined by semi-rigid joining as a simple structure.
また、床梁32,32間には、所定の間隔を置いて複数の小梁321,…が架け渡されている。 Further, a plurality of small beams 321,... Are bridged between the floor beams 32, 32 at a predetermined interval.
そして、図1の前面側の柱間2,2には、4枚の外壁としての外壁パネル5,…を取り付けるための5本の間柱4,…が配置されている。 1 are arranged between the front pillars 2 and 2 on the front side in FIG. 1 to attach four outer pillars 4,.
この間柱4は、上端が天井梁31に連結されるとともに、下端が床梁32に連結される。また、柱2に隣接する間柱4,4を除いた中間の3本の間柱4,4,4には、それぞれ2枚の別体の外壁パネル5,5の側縁が接合される。 The stud 4 has an upper end connected to the ceiling beam 31 and a lower end connected to the floor beam 32. Further, the side edges of two separate outer wall panels 5 and 5 are joined to the three intermediate columns 4, 4, 4 except for the intermediate columns 4, 4 adjacent to the column 2.
この外壁パネル5の外側から見た正面図を図2(a)に、建物ユニット1の内側から見た裏面図を図2(b)に示す。 The front view seen from the outer side of this outer wall panel 5 is shown to Fig.2 (a), and the back view seen from the inner side of the building unit 1 is shown to FIG.2 (b).
この外壁パネル5は、矩形の面材としての硬質木片セメント板(板状外壁材)52と、その裏面側の縁部を囲繞するように配置される装着部としてのフレーム51とから主に構成される。 This outer wall panel 5 is mainly composed of a hard wood piece cement board (plate-like outer wall material) 52 as a rectangular face material and a frame 51 as a mounting portion arranged so as to surround an edge portion on the back surface side thereof. Is done.
このフレーム51は、図2(b)に示されるように、2本の縦枠51b,51bと、その縦枠51b,51bの上端間及び下端間を繋ぐ横枠51c,51cと、その横枠51c,51c間に上下方向に間隔を置いて複数配置される中間枠51d,…とから主に構成される。 As shown in FIG. 2B, the frame 51 includes two vertical frames 51b and 51b, horizontal frames 51c and 51c connecting the upper and lower ends of the vertical frames 51b and 51b, and the horizontal frames. It is mainly composed of a plurality of intermediate frames 51d,... That are arranged at intervals in the vertical direction between 51c and 51c.
そして、この縦枠51b,51bには、棒状連結材としてのリベット6を挿通させる孔としてのリベット孔51aが、上下方向に間隔を置いて複数開口されている。 In the vertical frames 51b and 51b, a plurality of rivet holes 51a as holes through which the rivets 6 as rod-like connecting members are inserted are opened at intervals in the vertical direction.
また、図2(a)に示すように、硬質木片セメント板52は、複数本のスクリュー釘52a,…によってフレーム51の縦枠51b,51bと横枠51c,51cと中間枠51d,…とに固定(接合)されている。 Further, as shown in FIG. 2 (a), the hard wood piece cement board 52 is divided into a vertical frame 51b, 51b, a horizontal frame 51c, 51c and an intermediate frame 51d,. It is fixed (joined).
この外壁パネル5の断面図を図3に示す。この図3に示すように、硬質木片セメント板52とフレーム51の縦枠51b,51bとがウレタン系の接着剤53によって接合されている。また、硬質木片セメント板52とフレーム51の横枠51c,51c及び中間枠51d,…とがスクリュー釘52a,…のみで接合されている。 A sectional view of the outer wall panel 5 is shown in FIG. As shown in FIG. 3, the hard wood piece cement board 52 and the vertical frames 51 b and 51 b of the frame 51 are joined together by a urethane-based adhesive 53. Further, the hard wood piece cement plate 52 and the horizontal frames 51c, 51c and the intermediate frames 51d,... Of the frame 51 are joined only by the screw nails 52a,.
すなわち、所定の接合強度が要求される所定部分である縦枠51b,51bの部分が接着剤53とスクリュー釘52a,…とによって接合されている。また、所定強度が要求されない部分、すなわち、所定部分以外の他の部分である横枠51c,51c及び中間枠51d,…の部分がスクリュー釘52a,…のみで接合されている。 That is, the portions of the vertical frames 51b and 51b, which are predetermined portions that require a predetermined bonding strength, are bonded by the adhesive 53 and the screw nails 52a. Further, the portions where the predetermined strength is not required, that is, the portions of the horizontal frames 51c, 51c and the intermediate frames 51d,... Other than the predetermined portion are joined only by the screw nails 52a,.
つまり、硬質木片セメント板52とフレーム51の縦枠51b,51bとの接合強度が大きく(強く)設定され、硬質木片セメント板52とフレーム51の横枠51c,51c及び中間枠51d,…との接合強度が小さく(弱く)設定されている。また、硬質木片セメント板52の表面には、剛性の高いタイル状の複数の表面部材(図示せず)が接合されているが、ここではその説明は省略する。 That is, the joint strength between the hard wood cement plate 52 and the vertical frames 51b and 51b of the frame 51 is set to be large (strong), and the hard wood cement plate 52 and the horizontal frames 51c and 51c and the intermediate frames 51d,. The bonding strength is set small (weak). Further, a plurality of highly rigid tile-shaped surface members (not shown) are joined to the surface of the hard wood cement board 52, but the description thereof is omitted here.
また、間柱4と外壁パネル5とは、図3に示すように、棒状連結材としてのリベット6によって接合される。このリベット6は、ワンサイドリベットであり、間柱4側から打ち込むだけでフレーム51と間柱4とを接合することができる。
[作 用]
次に、上記のように構成される外壁パネル5の作用について説明する。
Further, as shown in FIG. 3, the stud 4 and the outer wall panel 5 are joined by a rivet 6 as a rod-like connecting material. The rivet 6 is a one-side rivet, and the frame 51 and the stud 4 can be joined simply by driving in from the stud 4 side.
[Operation]
Next, the operation of the outer wall panel 5 configured as described above will be described.
外壁パネル5は、太陽光などによって硬質木片セメント板52が乾燥して収縮しても、硬質木片セメント板52とフレーム51の横枠51c,51c及び中間枠51d,…との接合が弱く設定されていることにより、すなわち、横枠51c,51c及び中間枠51d,…による硬質木片セメント板52に対する変形拘束が弱いことにより、硬質木片セメント板52の裏面側も収縮していくことができる。このため、硬質木片セメント板52の表面だけが収縮してしまうことがなく、硬質木片セメント板52の反り変形が抑制されることになる。 The outer wall panel 5 is set so that the hard wood cement plate 52 and the horizontal frames 51c and 51c of the frame 51 and the intermediate frames 51d,... In other words, since the deformation restraint on the hard wood piece cement plate 52 by the horizontal frames 51c, 51c and the intermediate frames 51d,... Is weak, the back surface side of the hard wood piece cement plate 52 can also contract. For this reason, only the surface of the hard wood piece cement board 52 is not contracted, and the warp deformation of the hard wood piece cement board 52 is suppressed.
同様に、硬質木片セメント板52が膨張した際も、横枠51c,51c及び中間枠51d,…による硬質木片セメント板52に対する変形拘束が弱いことにより、硬質木片セメント板52の裏面側も膨張していくことができる。このため、硬質木片セメント板52の表面だけが膨張してしまうことがなく、硬質木片セメント板52の反り変形が抑制されることになる。 Similarly, when the hard wood cement board 52 expands, the back side of the hard wood cement board 52 also expands due to weak deformation restraint on the hard wood cement board 52 by the horizontal frames 51c, 51c and the intermediate frames 51d,. Can continue. For this reason, only the surface of the hard wood piece cement board 52 does not expand, and the warp deformation of the hard wood piece cement board 52 is suppressed.
また、硬質木片セメント板52とフレーム51の横枠51c,51c及び中間枠51d,…との接合強度が小さくても、硬質木片セメント板52とフレーム51の縦枠51b,51bとの接合強度が大きくなっていることにより、硬質木片セメント板52が外力によってフレーム51から外れてしまうなどの不具合は生じない。 Further, even if the joining strength between the hard wood cement board 52 and the horizontal frames 51c and 51c and the intermediate frames 51d,... Of the frame 51 is small, the joining strength between the hard wood cement board 52 and the vertical frames 51b and 51b of the frame 51 is low. Due to the increase in size, there is no problem such that the hard wood piece cement board 52 is detached from the frame 51 by an external force.
上記実施例では、横枠51c,51c及び中間枠51d,…は、スクリュー釘52aだけで硬質木片セメント板52に接合されているが、所定値以上の弾性率P1、すなわち接着剤53の弾性率よりも大きい弾性率P1を有する接着剤でその部分を接合してもよい。この場合、接着剤が所定値以上の弾性率P1を有することにより、横枠51c,51c及び中間枠51d,…の硬質木片セメント板52に対する変形拘束が弱く、このため上述のように硬質木片セメント板52の反り変形を抑制することができる。 In the above embodiment, the horizontal frames 51c, 51c and the intermediate frames 51d,... Are joined to the hard wood piece cement board 52 only by the screw nails 52a, but the elastic modulus P1 of the predetermined value or more, that is, the elastic modulus of the adhesive 53 The part may be joined with an adhesive having a larger elastic modulus P1. In this case, since the adhesive has an elastic modulus P1 of a predetermined value or more, the deformation restraint of the horizontal frames 51c, 51c and the intermediate frames 51d,... With respect to the hard wood piece cement board 52 is weak, and therefore, the hard wood piece cement as described above. Warpage deformation of the plate 52 can be suppressed.
また、横枠51c,51cと硬質木片セメント板52とを接着剤で接合することにより、フレーム51の縁部を接着剤53及び接着剤で囲繞することができる。このため、フレーム51と硬質木片セメント板52との間に水が浸入し難くなり、接合部の劣化を防止することができる。 Moreover, the edge part of the flame | frame 51 can be enclosed with the adhesive agent 53 and an adhesive agent by joining the horizontal frames 51c and 51c and the hard wood piece cement board 52 with an adhesive agent. For this reason, it becomes difficult for water to enter between the frame 51 and the hard wood piece cement board 52, and deterioration of the joint portion can be prevented.
また、所定値以上の弾性率P1の接着剤で接合する場合、その横枠51c,51c及び中間枠51d,…の部分のスクリュー釘52aを省略してもよい。この場合、所定以上の接合強度が得られる接着剤53の場合、縦枠51b,51bのスクリュー釘52aを省略してもよい。 Moreover, when joining with the adhesive agent of the elasticity modulus P1 more than predetermined value, you may abbreviate | omit the screw nails 52a of the part of the horizontal frames 51c and 51c and the intermediate frames 51d. In this case, in the case of the adhesive 53 that provides a predetermined or higher bonding strength, the screw nails 52a of the vertical frames 51b and 51b may be omitted.
図4及び図5は、硬質木片セメント板52の表面全体を覆うように剛性の高いタイル状の複数の表面部材151を密に接着剤(図示せず)で接合した外壁パネル150を示す。硬質木片セメント板52の裏面には、上述のようにフレーム51が接合されている。 4 and 5 show an outer wall panel 150 in which a plurality of highly rigid tile-like surface members 151 are tightly joined with an adhesive (not shown) so as to cover the entire surface of the hard wood cement board 52. FIG. The frame 51 is joined to the back surface of the hard wood piece cement board 52 as described above.
各表面部材151は、上下方向に対して左右方向にずらして配置したものであり、これを左右に一対設けたものである。 Each surface member 151 is arranged so as to be shifted in the left-right direction with respect to the up-down direction, and a pair thereof is provided on the left and right.
表面部材151を接合した接着剤の弾性率P2は、上記の弾性率P1より小さく設定されている。すなわち、弾性率P2は所定の設定値以下に設定されている。 The elastic modulus P2 of the adhesive bonded with the surface member 151 is set smaller than the elastic modulus P1. That is, the elastic modulus P2 is set to a predetermined set value or less.
外壁パネル150は、フレーム51の縦枠51b,51bと横枠51c,51cと中間枠51d,…とが接着剤53によって硬質木片セメント板52に接合されるとともに、複数のスクリュー釘52aによって接合されているが、上述と同様に、弾性率P1の接着剤で接合する場合の横枠51c,51c及び中間枠51d,…の部分のスクリュー釘52aを省略してもよく、また、所定以上の接合強度が得られる接着剤53の場合の縦枠51b,51bのスクリュー釘52aを省略してもよい。 In the outer wall panel 150, the vertical frames 51b and 51b, the horizontal frames 51c and 51c, and the intermediate frames 51d,... Of the frame 51 are bonded to the hard wood piece cement board 52 by an adhesive 53 and bonded by a plurality of screw nails 52a. However, in the same manner as described above, the screw nails 52a in the horizontal frames 51c, 51c and the intermediate frames 51d,... In the case of bonding with an adhesive having an elastic modulus P1 may be omitted. The screw nails 52a of the vertical frames 51b and 51b in the case of the adhesive 53 that provides strength may be omitted.
また、表面部材151の厚さは、所定以上の剛性を得るために所定の厚さH以上となっている。 Further, the thickness of the surface member 151 is equal to or greater than a predetermined thickness H in order to obtain a predetermined rigidity or more.
この外壁パネル150によれば、硬質木片セメント板52の表面に剛性の高い表面部材151を接合させたものであるから、硬質木片セメント板52の表面の変形拘束が強くなり、上述と同様に硬質木片セメント板52の反り変形を抑制することができる。 According to the outer wall panel 150, since the surface member 151 having high rigidity is joined to the surface of the hard wood piece cement plate 52, the deformation restraint on the surface of the hard wood piece cement plate 52 becomes strong, and it is hard as described above. Warpage deformation of the wood piece cement board 52 can be suppressed.
また、この実施例では、硬質木片セメント板52の表面全体を覆うように表面部材151を密に接合したが、その表面の被覆率は、硬質木片セメント板52の反り変形を十分に抑制可能な所定被覆率以上であればよい。 Further, in this embodiment, the surface member 151 is closely joined so as to cover the entire surface of the hard wood piece cement board 52, but the coverage of the surface can sufficiently suppress the warp deformation of the hard wood cement board 52. What is necessary is just to be more than a predetermined coverage.
図6は、他の例の外壁パネル160を示す。この外壁パネル160は、表面部材161を縦横に一直線状に並ぶように配置したものであり、他の構成は外壁パネル150と同様な構成なので、その説明は省略する。 FIG. 6 shows another example outer wall panel 160. The outer wall panel 160 is configured such that the surface members 161 are arranged in a straight line in the vertical and horizontal directions, and the other configuration is the same as that of the outer wall panel 150, and thus the description thereof is omitted.
この発明は、上記実施例に限られるものではなく、特許請求の範囲の発明の要旨を逸脱しない限り、設計の変更や追加等は許容される。 The present invention is not limited to the above-described embodiments, and design changes and additions are permitted without departing from the scope of the claimed invention.
