Description

本発明は、上下に離間して配置された上下の構造材間に、耐力面材が架設されてなる建物の補強構造に関する。 The present invention relates to a reinforcing structure for a building in which a load bearing member is provided between upper and lower structural members that are spaced apart from each other.

住宅等の建物内に立設される壁は、特に洋間の場合において、筋交い等が設けられることによって耐震性の耐力壁として用いられる（例えば、特許文献１参照）。このような洋間の壁は大壁方式であり、柱を見せる必要がなく、ベニヤ板やボードで柱を塞ぐので、中に筋交いを入れても美観が損なわれることはなく、補強された耐力壁とすることができる。 A wall erected in a building such as a house is used as a seismic load-bearing wall by providing braces or the like, particularly in the case of the ocean (see, for example, Patent Document 1). Such a wall between the oceans is a large wall system, it is not necessary to show the pillars, and the pillars are closed with plywood or board, so the beauty is not impaired even if bracing is put in, and the reinforced bearing wall can do.

一方、日本間の壁の場合は真壁方式であり、柱の美しさを失わせず、柱は外に出て見せるようにしなければならないため、従来は木舞を組んだ下地材を左右の柱間に介在せしめ、下地材に壁土を塗って仕上げをすることにより壁を構成していた。
また、近年においては左右の柱間に介在せしめたラスボードに仕上げ塗りをして日本間の壁を構成している。
特開２００２−１０６０６７号公報 On the other hand, the wall between Japan is a true wall system, and the beauty of the pillars must be kept without losing the beauty of the pillars. The walls were constructed by interposing them and painting the base material with wall soil and finishing it.
In recent years, the walls between Japan have been constructed by finishing the lath board interposed between the left and right pillars.
JP 2002-106067 A

ところが、上述した日本間の壁のように、柱を外に出して見せるようにすると、その分、壁厚を薄くしなければならないので、洋間の壁に比して、壁内に筋交い等の設置スペースを確保することが困難となり、耐力壁としての機能に乏しい。 However, like the above-mentioned wall between Japan, if the pillars are exposed outside, the wall thickness must be reduced accordingly, so that the bracing in the wall, etc. It becomes difficult to secure the installation space, and the function as a bearing wall is poor.

本発明の課題は、住宅等の建物に真壁方式の壁を設けるに際し、従来とは異なり、耐震性において格段に優れる建物の補強構造を提供することを目的とする。 An object of the present invention is to provide a reinforcing structure for a building that is significantly superior in earthquake resistance, unlike a conventional case, when a wall of a true wall type is provided in a building such as a house.

請求項１に記載の発明は、例えば図１〜図３に示すように、上下に離間して配置された上下の構造材１，２間に、耐力面材３が架設されてなる建物の補強構造において、
前記上構造材１の下面および下構造材２の上面には、これら上下の構造材１，２の長手方向に沿って、それぞれ溝部１ａ，２ａが形成されているとともに、前記耐力面材３の上下端部には、この耐力面材３を前記上下の構造材１，２に固定するための固定部材４，４が設けられており、
これら固定部材４，４は、前記耐力面材３に固定される固定部４ａと、この固定部４ａと一体的に形成され、かつ前記溝部１ａ，２ａに挿入されて嵌合する断面視略楔形の嵌合部４ｂと、前記固定部４ａと嵌合部４ｂとを貫通して形成された貫通孔５とを備えており、
前記固定部材４，４は、前記上下の構造材１，２に対して、前記溝部１ａ,２ａに塗布された接着剤１０によって接着固定されるとともに、止着材１１を前記貫通孔５に挿通して上下の構造材１，２に設けることによって固定されていることを特徴とする。 The invention according to claim 1, for example, as shown in FIGS. 1 to 3 , reinforces a building in which a load bearing member 3 is laid between upper and lower structural members 1 and 2 that are spaced apart from each other. In structure
On the lower surface of the upper structural member 1 and the upper surface of the lower structural member 2, grooves 1a and 2a are formed along the longitudinal direction of the upper and lower structural members 1 and 2, respectively. Fixing members 4 and 4 for fixing the load bearing surface material 3 to the upper and lower structural members 1 and 2 are provided at the upper and lower ends,
The fixing members 4 and 4 are fixed to the load-bearing face member 3 and a fixed portion 4a, which is formed integrally with the fixed portion 4a, and is inserted into the groove portions 1a and 2a and fitted in a substantially wedge shape in cross section. A fitting portion 4b, and a through hole 5 formed through the fixing portion 4a and the fitting portion 4b .
The fixing members 4 and 4 are bonded and fixed to the upper and lower structural members 1 and 2 by an adhesive 10 applied to the groove portions 1a and 2a, and the fixing member 11 is inserted into the through hole 5. The upper and lower structural members 1 and 2 are fixed by being provided .

請求項１に記載の発明によれば、前記固定部材４，４の嵌合部４ｂ，４ｂが前記溝部１ａ，２ａに挿入されて嵌合するので、この固定部材４，４を前記上下の構造材１，２に対して確実、かつ強固に取り付けることができる。さらに、前記耐力面材３の上下端部に、このような固定部材４，４が設けられているので、耐力面材３を前記上下の構造材１，２間に架け渡して確実、かつ強固に設置することができる。これによって、前記耐力面材３が架設された位置に耐力を有する耐力壁を構築することができる。
また、このようにして耐力面材３を架設することで耐力壁を構築することができるので、例えば住宅等の建物内に真壁方式の壁を構築する際において柱を外に出して見せ、壁厚を薄くしたとしても、十分な耐震性を確保することができる。したがって、住宅等の建物に真壁方式の壁を設けるに際し、従来とは異なり、耐震性において格段に優れる。
また、前記貫通孔５は、前記固定部４ａと嵌合部４ｂとを貫通して形成されているので、止着材１１を貫通孔５に挿通して前記上下の構造材１，２に設けることで、前記固定部材４，４を上下の構造材１，２に固定する際の補助となる。これによって、前記固定部材４，４を上下の構造材１，２に対してより確実、かつ強固に取り付けることができる。 According to the first aspect of the present invention, since the fitting portions 4b and 4b of the fixing members 4 and 4 are inserted and fitted into the groove portions 1a and 2a, the fixing members 4 and 4 are connected to the upper and lower structures. It can be securely and firmly attached to the materials 1 and 2. Furthermore, since the fixing members 4 and 4 are provided at the upper and lower ends of the load bearing face 3, the load bearing face 3 is bridged between the upper and lower structural members 1 and 2 so as to be sure and strong. Can be installed. As a result, it is possible to construct a load bearing wall having strength at the position where the load bearing face material 3 is installed.
In addition, since the load bearing wall can be constructed by laying the load bearing face material 3 in this way, for example, when building a wall of a true wall type in a building such as a house, the column is shown to the outside, Even if the thickness is reduced, sufficient earthquake resistance can be ensured. Therefore, when providing a wall of a true wall type in a building such as a house, unlike the conventional case, the earthquake resistance is remarkably excellent.
Further, since the through hole 5 is formed through the fixing portion 4a and the fitting portion 4b, the fastening material 11 is inserted into the through hole 5 and provided in the upper and lower structural materials 1 and 2. Thus, the fixing members 4 and 4 are assisted in fixing to the upper and lower structural members 1 and 2. Thereby, the fixing members 4 and 4 can be more securely and firmly attached to the upper and lower structural members 1 and 2.

請求項２に記載の発明は、例えば図３に示すように、請求項１に記載の建物の補強構造において、

すなわち、このようにボルト孔７を前記貫通孔５と直交する方向にすることによって、例えば地震等によって前記耐力面材３に変形を起こそうとする力が加わった際に、この力の方向が前記溝部１ａ，２ａから固定部材４，４が離脱する方向とは異なる方向となるので、地震等による固定部材４，４の離脱を確実に防ぐことができる。 According to the invention described in claim 2 , the bolt hole 7 is formed through the fixing portion 4 a in a direction orthogonal to the through hole 5. The bolt 6 is inserted into the bolt hole 7 in the horizontal direction with respect to the fixing member 4 provided in the vertical direction.
That is, by making the bolt hole 7 in a direction orthogonal to the through-hole 5 in this way, when a force is applied to the load bearing face 3 due to an earthquake or the like, the direction of this force is changed. Since the direction is different from the direction in which the fixing members 4 and 4 are detached from the grooves 1a and 2a, the separation of the fixing members 4 and 4 due to an earthquake or the like can be reliably prevented.

請求項３に記載の発明は、例えば図３に示すように、請求項２に記載の建物の補強構造において、
前記貫通孔５およびボルト孔７は、それぞれ前記固定部材４の長手方向に沿って複数並列されており、各ボルト孔７，７…は、隣り合う貫通孔５，５間に配置されていることを特徴とする。 The invention according to claim 3 is a reinforcing structure for a building according to claim 2 , for example, as shown in FIG.

また、各ボルト孔７，７…は、隣り合う貫通孔５，５間に配置されていることから、例えば纏まりなく順序不同に配置された場合に比して、耐力面材３と固定部材４，４との接合部分や、上下の構造材１，２と固定部材４，４の当接箇所にかかる力の偏りがなくなるので、バランス良く地震等の力に対応することができる。 According to the invention described in claim 3 , a plurality of the through holes 5 and the bolt holes 7 are juxtaposed along the longitudinal direction of the fixing member 4. While being able to attach to 1 and 2 more reliably and firmly, separation of fixing members 4 and 4 can be prevented more reliably.
Moreover, since each bolt hole 7,7 ... is arrange | positioned between the adjacent through-holes 5,5, compared with the case where it arrange | positions in random order, for example, the load bearing surface material 3 and the fixing member 4 are arranged. , 4 and the bias of the force applied to the contact portions of the upper and lower structural members 1, 2 and the fixing members 4, 4 are eliminated.

請求項４に記載の発明は、例えば図１に示すように、請求項１〜３のいずれか一項に記載の建物の補強構造において、
前記溝部１ａ，２ａの断面形状は、前記嵌合部４ｂ，４ｂが嵌合可能な形状であることを特徴とする。 The invention according to claim 4, for example, as shown in FIG. 1, the reinforcing structure of a building according to any one of claims 1 to 3
The cross-sectional shape of the groove 1 a, 2 a, the fitting portion 4 b, 4 b is characterized in that it is a shape to be fitted.

請求項４に記載の発明によれば、前記溝部１ａ，２ａの断面形状は、前記嵌合部４ｂ，４ｂが嵌合可能な形状であることから、この嵌合部４ｂ，４ｂを溝部１ａ，２ａに確実に挿入して嵌合することができるので、前記固定部材４，４を前記上下の構造材１，２に対して、より一層確実に、かつ強固に取り付けることができる。 According to the invention described in claim 4, the cross-sectional shape of the groove 1 a, 2 a, since the fitting portion 4 b, 4 b are fittable shape, the fitting portion 4 b, 4 b can be securely inserted and fitted into the grooves 1 a and 2 a, so that the fixing members 4 and 4 are more securely and firmly attached to the upper and lower structural members 1 and 2. Can be attached.

本発明によれば、固定部材の嵌合部が溝部に挿入されて嵌合するので、この固定部材を上下の構造材に対して確実、かつ強固に取り付けることができる。さらに、耐力面材の上下端部に、このような固定部材が設けられているので、耐力面材を前記上下の構造材間に架け渡して確実、かつ強固に設置することができる。これによって、前記耐力面材が架設された位置に耐力を有する耐力壁を構築することができる。
また、このようにして耐力面材を架設することで耐力壁を構築することができるので、例えば住宅等の建物内に真壁方式の壁を構築する際において柱を外に出して見せ、壁厚を薄くしたとしても、十分な耐震性を確保することができる。したがって、住宅等の建物に真壁方式の壁を設けるに際し、従来とは異なり、耐震性において格段に優れる。 According to the present invention, since the fitting portion of the fixing member is inserted and fitted into the groove portion, the fixing member can be securely and firmly attached to the upper and lower structural members. Furthermore, since such fixing members are provided at the upper and lower ends of the load bearing face material, the load bearing face material can be bridged between the upper and lower structural members and installed reliably and firmly. As a result, it is possible to construct a load-bearing wall having strength at the position where the load-bearing face material is installed.
In addition, since the load bearing wall can be constructed by laying the load bearing face material in this way, for example, when building a true wall type wall in a building such as a house, the column is shown to the outside, and the wall thickness Even if it is made thinner, sufficient earthquake resistance can be ensured. Therefore, when providing a wall of a true wall type in a building such as a house, unlike the conventional case, the earthquake resistance is remarkably excellent.

以下、図面を参照して本発明に係る建物の補強構造の実施の形態について説明する。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a building reinforcing structure according to the present invention will be described with reference to the drawings.

本実施の形態の建物の補強構造は、図１（ａ），（ｂ）に示すように、上下に離間して配置された上下の構造材１，２間に、耐力面材３が架設されてなるものであり、
前記上構造材１の下面および下構造材２の上面には、これら上下の構造材１，２の長手方向に沿って、それぞれ溝部１ａ，２ａが形成されているとともに、前記耐力面材３の上下端部には、この耐力面材３を前記上下の構造材１，２に固定するための固定部材４，４が設けられており、
これら固定部材４，４は、前記耐力面材３に固定される固定部４ａと、この固定部４ａと一体的に形成され、かつ前記溝部１ａ，２ａに挿入されて嵌合する嵌合部４ｂとを備えている。 As shown in FIGS. 1 (a) and 1 (b), the building reinforcing structure of the present embodiment has a load bearing member 3 installed between upper and lower structural members 1 and 2 that are spaced apart from each other. And
On the lower surface of the upper structural member 1 and the upper surface of the lower structural member 2, grooves 1a and 2a are formed along the longitudinal direction of the upper and lower structural members 1 and 2, respectively. Fixing members 4 and 4 for fixing the load bearing surface material 3 to the upper and lower structural members 1 and 2 are provided at the upper and lower ends,
The fixing members 4 and 4 include a fixing portion 4a fixed to the load-bearing face material 3, and a fitting portion 4b that is formed integrally with the fixing portion 4a and that is inserted into the groove portions 1a and 2a to be fitted. And.

ここで、前記上構造材１は、本実施の形態においては建物の躯体を構成する梁であり、前記下構造材２は土台である。したがって、本実施の形態では、前記耐力面材３は在来の木造軸組み工法で構築される建物の躯体に取り付けられるものである。
なお、本実施の形態における下構造材２は土台としたが、これに限られず梁でも良い。すなわち、本発明の建物の補強構造を、建物の１階部分に適用する場合と、建物の２階以上に適用する場合とで異なる。 Here, in the present embodiment, the upper structural material 1 is a beam constituting a building frame, and the lower structural material 2 is a foundation. Therefore, in the present embodiment, the load-bearing face material 3 is attached to a building frame constructed by a conventional wooden frame assembly method.
In addition, although the lower structure material 2 in this Embodiment was a foundation, it is not restricted to this, A beam may be sufficient. That is, the case where the building reinforcement structure of the present invention is applied to the first floor portion of the building is different from the case where it is applied to the second floor or more of the building.

前記耐力面材３は、本実施の形態においては構造用合板が用いられている。また、これに限られず鉄やアルミ等でも良く、耐力を有する板状のものであれば良い。なお、耐力面材３を鉄やアルミ等で構成する場合は、所定の耐力を備えつつ重さを軽くするために、例えばフレーム状に形成しても良い。 As the load bearing face 3, a structural plywood is used in the present embodiment. Moreover, it is not restricted to this, Iron, aluminum, etc. may be sufficient, and what is necessary is just a plate-shaped thing with proof stress. When the load bearing face material 3 is made of iron, aluminum, or the like, it may be formed in a frame shape, for example, in order to reduce the weight while providing a predetermined load resistance.

また、図１（ｂ）に示すように、前記耐力面材３の上下端部には、この耐力面材３と前記固定部材４，４とを接合するためのボルト６（後述する）を挿通するための挿通孔３ａが複数形成されている。 Further, as shown in FIG. 1 (b), bolts 6 (described later) for joining the load-bearing face material 3 and the fixing members 4, 4 are inserted into the upper and lower ends of the load-bearing face material 3. A plurality of insertion holes 3a are formed.

前記固定部材４は鋼製であり、図３に示すように、また、上述したように前記耐力面材３に固定される固定部４ａと、この固定部４ａと一体的に形成され、かつ前記溝部１ａ，２ａに挿入されて嵌合する嵌合部４ｂとを備えている。
また、この固定部材４を前記上下の構造材１，２に固定する際は、図２（ｂ）に示すように、接着剤１０による接着固定がなされる。 The fixing member 4 is made of steel, and as shown in FIG. 3, as described above, the fixing portion 4 a fixed to the load bearing surface 3, and the fixing portion 4 a, and is formed integrally with the fixing member 4 a, and And a fitting portion 4b that is inserted into and fitted into the groove portions 1a and 2a.
Further, when the fixing member 4 is fixed to the upper and lower structural members 1 and 2, as shown in FIG.

また、この固定部材４は、前記固定部４ａと嵌合部４ｂとを貫通して形成された複数の貫通孔５，５…を備えている。これにより、例えば止着材１１等を貫通孔５，５…に挿通して前記上下の構造材１，２に設けたり、貫通孔５，５…から接着剤１０を充填して前記嵌合部４ｂを溝部１ａ，２ａに定着させたりすることで、前記固定部材４，４を上下の構造材１，２に固定する際の補助となる。したがって、前記固定部材４，４を上下の構造材１，２に対してより確実、かつ強固に取り付けることができる。
なお、本実施の形態においては、図２（ｂ）に示すように、前記貫通孔５には止着材１１が挿通されており、前記接着剤１０とともに固定部材４，４を上下の構造材１，２に固定している。 The fixing member 4 includes a plurality of through holes 5, 5... Formed through the fixing portion 4a and the fitting portion 4b. Thereby, for example, the fastening material 11 or the like is inserted into the through-holes 5, 5... And provided in the upper and lower structural members 1, or the adhesive 10 is filled from the through-holes 5, 5. Fixing the fixing members 4 and 4 to the upper and lower structural members 1 and 2 by fixing the 4b in the groove portions 1a and 2a helps. Therefore, the fixing members 4 and 4 can be more securely and firmly attached to the upper and lower structural members 1 and 2.
In the present embodiment, as shown in FIG. 2B, a fastening material 11 is inserted into the through hole 5, and the fixing members 4, 4 are connected to the upper and lower structural materials together with the adhesive 10. 1 and 2 are fixed.

前記固定部４ａは、図１（ｂ）に示すように、前記耐力面材３の上下端部に当接する部分であり、前記ボルト６を挿通するためのボルト孔７が、この固定部４ａを貫通するようにして複数形成されている。この時、このボルト孔７，７…は、前記貫通孔５と直交する方向に形成されており、前記耐力面材３の上下端部に形成された複数の挿通孔３ａと重なり合うように配置されている。 As shown in FIG. 1 (b), the fixing portion 4a is a portion that comes into contact with the upper and lower end portions of the load-bearing face material 3, and a bolt hole 7 through which the bolt 6 is inserted is connected to the fixing portion 4a. A plurality are formed so as to penetrate. At this time, the bolt holes 7, 7... Are formed in a direction orthogonal to the through-hole 5, and are arranged so as to overlap with the plurality of insertion holes 3a formed in the upper and lower ends of the load-bearing face material 3. ing.

このように前記ボルト孔７が、前記貫通孔５と直交する方向に前記固定部４ａを貫通して形成されているので、前記上下の構造材１，２に、上下向きに設けられる固定部材４，４に対して、前記ボルト６は水平向きにボルト孔７に挿通されることになる。
すなわち、このようにボルト孔７を前記貫通孔５と直交する方向にすることによって、例えば地震等によって前記耐力面材３に変形を起こそうとする力が加わった際に、この力の方向が前記溝部１ａ，２ａから固定部材４，４が離脱する方向とは異なる方向となるので、地震等による固定部材４，４の離脱を確実に防ぐことができるようになっている。 Since the bolt hole 7 is formed through the fixing portion 4a in a direction orthogonal to the through hole 5 in this way, the fixing member 4 provided in the upper and lower structural members 1 and 2 in the vertical direction. , 4, the bolt 6 is inserted into the bolt hole 7 in the horizontal direction.
That is, by making the bolt hole 7 in a direction orthogonal to the through-hole 5 in this way, when a force is applied to the load bearing face 3 due to an earthquake or the like, the direction of this force is changed. Since the direction is different from the direction in which the fixing members 4, 4 are detached from the grooves 1a, 2a, the separation of the fixing members 4, 4 due to an earthquake or the like can be reliably prevented.

また、前記貫通孔５およびボルト孔７は、図３に示すように、それぞれ前記固定部材４の長手方向に沿って複数並列されており、各ボルト孔７，７…は、隣り合う貫通孔５，５間に配置された状態となっている。
つまり、このように前記貫通孔５およびボルト孔７が、それぞれ前記固定部材４の長手方向に沿って複数並列されているので、前記固定部材４，４を上下の構造材１，２に対してさらに確実、かつ強固に取り付けできるとともに、固定部材４，４の離脱をさらに確実に防ぐことができる。
しかも、各ボルト孔７，７…が、隣り合う貫通孔５，５間に配置されていることから、例えば纏まりなく順序不同に配置された場合に比して、耐力面材３と固定部材４，４との接合部分や、上下の構造材１，２と固定部材４，４との当接箇所にかかる力の偏りがなくなるので、バランス良く地震等の力に対応することができる。 Further, as shown in FIG. 3, a plurality of the through holes 5 and the bolt holes 7 are juxtaposed along the longitudinal direction of the fixing member 4, and each of the bolt holes 7, 7. , 5 are arranged.
That is, since the plurality of the through holes 5 and the bolt holes 7 are arranged in parallel along the longitudinal direction of the fixing member 4 as described above, the fixing members 4, 4 are connected to the upper and lower structural members 1, 2. In addition, the fixing members 4 and 4 can be more reliably prevented from being detached while being securely and firmly attached.
And since each bolt hole 7,7 ... is arrange | positioned between the adjacent through-holes 5,5, compared with the case where it arrange | positions in random order, for example, the load bearing surface material 3 and the fixing member 4 are sufficient. , 4 and the bias of the force applied to the contact portions between the upper and lower structural members 1 and 2 and the fixing members 4 and 4 are eliminated.

一方、前記嵌合部４ｂは、前記溝部１ａ，２ａに挿入される部分であり、断面視略楔形に形成されている。なお、この嵌合部４ｂが挿入される溝部１ａ，２ａの断面形状は、嵌合部４ｂが嵌合可能な形状となっており、これによって、嵌合部４ｂを溝部１ａ，２ａに確実に挿入して嵌合することができるので、前記固定部材４，４を前記上下の構造材１，２に対して、より一層確実に、かつ強固に取り付けることができる。 On the other hand, the fitting portion 4b is a portion inserted into the groove portions 1a and 2a, and is formed in a substantially wedge shape in cross section. In addition, the cross-sectional shape of the groove portions 1a and 2a into which the fitting portion 4b is inserted is a shape that allows the fitting portion 4b to be fitted, so that the fitting portion 4b can be securely inserted into the groove portions 1a and 2a. Since they can be inserted and fitted, the fixing members 4 and 4 can be attached to the upper and lower structural members 1 and 2 more reliably and firmly .

なお、本実施の形態において前記嵌合部４ｂを楔形としたのは、接着剤１０を塗布する面が広く、接着面積を稼ぐことができるためである。 In the present embodiment, the reason why the fitting portion 4b is wedge-shaped is that the surface on which the adhesive 10 is applied is wide and the bonding area can be increased .

次に、図面を参照して、以上のような建物の補強構造を採用した建物内の耐力壁の構築方法について説明する。 Next, with reference to the drawings, a method for constructing a load-bearing wall in a building that employs the building reinforcing structure as described above will be described.

まず、図２（ａ）に示すように、予め工場等で前記上構造材１の下面および下構造材２の上面に溝部１ａ，２ａを形成しておく。そして、図２（ｂ）に示すように、溝部１ａ，２ａに対して前記固定部材４，４の嵌合部４ｂ，４ｂを挿入して嵌合させる。この時、固定部材４の固定方法としては、前記溝部１ａ，２ａに接着剤１０を塗布しておくとともに、嵌合部４ｂを挿入して嵌合させた後、前記貫通孔５に止着材１１を挿通して固定部材４，４を上下の構造材１，２に固定するものである。 First, as shown in FIG. 2A, grooves 1a and 2a are formed in advance on the lower surface of the upper structural member 1 and the upper surface of the lower structural member 2 at a factory or the like. And as shown in FIG.2 (b), the fitting parts 4b and 4b of the said fixing members 4 and 4 are inserted and fitted with respect to the groove parts 1a and 2a. At this time, as a fixing method of the fixing member 4, the adhesive 10 is applied to the groove portions 1 a and 2 a, and after the fitting portion 4 b is inserted and fitted, the fixing material is fixed to the through hole 5. 11, the fixing members 4 and 4 are fixed to the upper and lower structural members 1 and 2, respectively.

次に、以上のように固定部材４，４が予め取り付けられた上下の構造材１，２を現場まで輸送し、現場で躯体を構築する作業を進める。そして、上下の構造材１，２を所定の位置に設けた後、図１（ａ），（ｂ）に示すように、これら上下の構造材１，２に取り付けられた固定部材４，４と、前記耐力面材３とをボルト６によって接合する。 Next, the upper and lower structural members 1 and 2 to which the fixing members 4 and 4 are attached in advance as described above are transported to the site, and the work for constructing the housing at the site is advanced. Then, after the upper and lower structural members 1 and 2 are provided at predetermined positions, as shown in FIGS. 1A and 1B, the fixing members 4 and 4 attached to the upper and lower structural members 1 and 4 and The load-bearing face material 3 is joined with a bolt 6.

続いて、図示はしないが、壁面を構成する壁板材を、前記上下の構造材１，２間に架け渡すようにして設置する。この時、壁板材を前記耐力面材３に近づけて設置することで、柱や梁を外に出して見せることができる。したがって、優れた耐震性を備えた耐力壁を設けることができるだけでなく、意匠性にも優れ、見映えの良い真壁方式の壁を得ることもできる。
また、予め工場で前記固定部材４，４を上下の構造材１，２に取り付けておくことによって、現場ではこれら固定部材４，４に耐力面材３を架設するだけで済むので、施工性の向上を図ることができ、工期の短縮を図ることが可能となる。 Subsequently, although not shown, the wall plate material constituting the wall surface is installed so as to be bridged between the upper and lower structural materials 1 and 2. At this time, by placing the wall plate material close to the load bearing surface material 3, the pillars and beams can be shown outside. Therefore, it is possible not only to provide a load-bearing wall having excellent earthquake resistance, but also to obtain a true wall type wall that is excellent in design and looks good.
In addition, by attaching the fixing members 4 and 4 to the upper and lower structural members 1 and 2 in advance at the factory, it is only necessary to construct the load bearing surface material 3 on the fixing members 4 and 4 at the site. Improvement can be achieved and the construction period can be shortened.

本実施の形態によれば、固定部材４，４の嵌合部４ｂ，４ｂが溝部１ａ，２ａに挿入されて嵌合するので、この固定部材４，４を上下の構造材１，２に対して確実、かつ強固に取り付けることができる。さらに、耐力面材３の上下端部に、このような固定部材４，４が設けられているので、耐力面材３を前記上下の構造材１，２間に架け渡して確実、かつ強固に設置することができる。これによって、前記耐力面材３が架設された位置に耐力を有する耐力壁を構築することができる。
また、このようにして耐力面材３を架設することで耐力壁を構築することができるので、例えば住宅等の建物内に真壁方式の壁を構築する際において柱を外に出して見せ、壁厚を薄くしたとしても、十分な耐震性を確保することができる。したがって、住宅等の建物に真壁方式の壁を設けるに際し、従来とは異なり、耐震性において格段に優れる。 According to the present embodiment, since the fitting portions 4b and 4b of the fixing members 4 and 4 are inserted and fitted into the groove portions 1a and 2a, the fixing members 4 and 4 are attached to the upper and lower structural members 1 and 2, respectively. Can be attached securely and securely. Furthermore, since such fixing members 4 and 4 are provided at the upper and lower ends of the load bearing surface 3, the load bearing surface 3 is bridged between the upper and lower structural members 1 and 2 securely and firmly. Can be installed. As a result, it is possible to construct a load bearing wall having strength at the position where the load bearing face material 3 is installed.
In addition, since the load bearing wall can be constructed by laying the load bearing face material 3 in this way, for example, when building a wall of a true wall type in a building such as a house, the column is shown to the outside, Even if the thickness is reduced, sufficient earthquake resistance can be ensured. Therefore, when providing a wall of a true wall type in a building such as a house, unlike the conventional case, the earthquake resistance is remarkably excellent.

また、このような耐力壁を建物内に設けることができるので、地震だけに限られず、例えば風や交通振動等によって建物に発生した種々の揺れ・振動に対しても優れた効果を発揮することができる。 In addition, because such a bearing wall can be provided in the building, it is not limited to earthquakes, and it exhibits excellent effects against various vibrations and vibrations generated in the building due to wind, traffic vibration, etc. Can do.
