Description

本発明は、断面形状を同じくする複数の棒材から構成された木製耐震壁に関する。   The present invention relates to a wooden seismic wall composed of a plurality of bars having the same cross-sectional shape.

従来、木造建築物における壁は、水平および鉛直方向にそれぞれ配設した桟材の両面に板材を貼り付けたものが多い(例えば特許文献1参照)。このような従来の木造壁の場合、面内方向の剛性が大きいため、面内方向の変形能力に乏しく、地震時におけるエネルギー吸収能の低い壁となる。このため、大地震時には、これら木造壁が脆性的に破壊するおそれがある。   2. Description of the Related Art Conventionally, many walls in wooden buildings have plate members attached to both sides of a crosspiece arranged in the horizontal and vertical directions (see, for example, Patent Document 1). In the case of such a conventional wooden wall, since the rigidity in the in-plane direction is large, the deformability in the in-plane direction is poor, and the wall has low energy absorption capacity during an earthquake. For this reason, there is a risk that these wooden walls will be brittlely destroyed during a major earthquake.

他方、特許文献2では、左右一対の柱材の上下両側にそれぞれ横材を架設して構成した主体枠と、前記左側柱材方向に傾斜上りにした複数本の傾斜材と前記右側柱材方向に傾斜上りにした複数本の他の傾斜材とを互いに係合させて組み付けてなる格子枠とから構成した木造建物用壁構成材の発明が開示されている。この発明では、格子枠が筋交いの機能を果たし、面内方向に大きな変形能力を有する構造となっている。

On the other hand, in Patent Document 2, a main frame constructed by laying cross members on the upper and lower sides of a pair of left and right column members, a plurality of inclined members inclined upward in the left column material direction, and the right column material direction An invention of a wall member for a wooden building is disclosed which is composed of a lattice frame formed by engaging and assembling a plurality of other inclined members that are inclined upward. In the present invention, the lattice frame functions as a brace and has a structure having a large deformation capability in the in-plane direction.

しかしながら、特許文献2に記載された発明の場合、予め傾斜材に係合溝を形成しておく必要があるため、加工に手間が掛かるという問題がある。また、この発明の場合、格子枠は大きな鉛直荷重を負担できず、格子枠に作用する鉛直荷重は左右の柱材に伝達されるようになっている。即ち、柱材に大きな負荷が掛かる構造になっている。   However, in the case of the invention described in Patent Document 2, it is necessary to form an engagement groove in the inclined member in advance, and there is a problem that it takes time for processing. In the present invention, the lattice frame cannot bear a large vertical load, and the vertical load acting on the lattice frame is transmitted to the left and right column members. In other words, the structure is such that a large load is applied to the column material.

本発明は、上述する問題点に鑑みてなされたもので、面内方向の変形能力に富み、しかも低コストで施工が容易な木製耐震壁を提供することを目的とする。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a wooden seismic wall that is rich in in-plane deformation capability and that is easy to construct at low cost.

本発明では、断面形状を同じくする複数の棒材を用いて木製耐震壁を構成しているので、安価な辺材を利用することができ、材料費を低く抑えることができる。また、同断面の棒材を格子状に組み合わせるだけなので熟練技術を必要とせず、施工が容易であることに加え、様々な断面寸法の木製耐震壁の製作が可能となる。
In order to achieve the above object, the present invention is a wooden earthquake-resistant wall composed of a plurality of bars having the same cross-sectional shape, and is arranged in parallel to the wall surface with an interval corresponding to the width of the bars.

In the wooden earthquake-resistant wall according to the present invention, it is preferable that at least one of the upper surface and the lower surface of the horizontal secondary material is not fixed to the horizontal main material.
In the present invention, since at least one of the upper surface or the lower surface of the horizontal secondary material is not fixed to the horizontal main material, the horizontal secondary material restrains the movement of the horizontal main material when an in-plane shearing force acts on the wooden seismic wall. Without exerting large shear deformation ability.

また、本発明に係る木製耐震壁では、壁体内に形成された空洞部および/または壁面に形成された凹陥部に、弾性体が充填されていてもよい。

In addition, since the rods having the same cross section are simply combined in a lattice shape, no skill is required and construction is easy. In addition, since at least one of the upper or lower surface of the horizontal secondary material is not fixed to the horizontal main material, the horizontal secondary material restrains the movement of the horizontal main material when an in-plane shear force is applied to the wooden seismic wall. Therefore, a large shear deformation ability can be exhibited.

以下、本発明の実施形態について図面に基づいて説明する。
図1に本発明に係る木製耐震壁の斜視図を、図2に本木製耐震壁の立面図および断面図をそれぞれ示す。
本木製耐震壁1は、18mm×18mmの正方形断面を有する棒材からなる鉛直材11と、前記棒材からなる水平主材12および水平副材13とから構成されている。具体的には、前記棒材の幅分の間隔をあけて壁面と平行に配設される水平主材12と、水平主材12の方向に前記棒材の幅分の間隔をあけて水平主材12,12間に配設される鉛直材11と、鉛直材11,11間に、水平主材12と直交するように配設される水平副材13とからなり、水平主材12および水平副材13は交互に積層して配設される。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a wooden earthquake resistant wall according to the present invention, and FIG. 2 is an elevation view and a sectional view of the wooden earthquake resistant wall.
The wooden seismic wall 1 is composed of a vertical member 11 made of a rod having a square cross section of 18 mm × 18 mm, a horizontal main member 12 and a horizontal auxiliary member 13 made of the rod. Specifically, the horizontal main member 12 disposed in parallel with the wall surface with an interval corresponding to the width of the bar member, and the horizontal main member 12 with an interval corresponding to the width of the bar member in the direction of the horizontal main member 12. It consists of a vertical member 11 disposed between the members 12, 12 and a horizontal sub member 13 disposed so as to be orthogonal to the horizontal main member 12 between the vertical members 11, 11, and the horizontal main member 12 and the horizontal member The auxiliary members 13 are alternately stacked.

但し、木製耐震壁1の上下端部16および両側端部17には、後述するように、組立梁から突出する梁副材もしくは組立柱から突出する柱副材が挿入されるため、水平副材13が配されていない。また、木製耐震壁1の両側端部17の水平主材12,12間には、水平主材12と同断面の補剛材15を水平主材12の方向に介装する。   However, since the beam submaterial protruding from the assembly beam or the column auxiliary material protruding from the assembly column is inserted into the upper and lower end portions 16 and both side end portions 17 of the wooden earthquake-resistant wall 1, the horizontal submaterial 13 is Not arranged. Further, a stiffening material 15 having the same cross section as that of the horizontal main material 12 is interposed in the direction of the horizontal main material 12 between the horizontal main materials 12 and 12 at both end portions 17 of the wooden earthquake-resistant wall 1.

鉛直材11と水平主材12とは、釘や接着剤などで一体に組み立てられるが、水平副材13は、水平主材12および鉛直材11に固着しないようにし、仮に固着するとしても、水平副材13の上面または下面の少なくとも一方のみが水平主材12に固着されるようにする。
図3は、本木製耐震壁1がせん断変形した状態を示したものであるが、水平副材13が水平主材12および粘弾性体14の背後にある鉛直材11に固着されていないため、水平主材12は水平副材13に拘束されずに水平方向にスライドすることができる。その結果、木製耐震壁1に面内せん断力が作用した際、大きくせん断変形することができる。
一方、水平主材12に作用する鉛直荷重は、水平副材13を介して下方の水平主材12に伝達されるため、鉛直材11に大きな負荷が掛かることはない。
The vertical member 11 and the horizontal main member 12 are integrally assembled with a nail, an adhesive, or the like. However, the horizontal auxiliary member 13 is not fixed to the horizontal main member 12 and the vertical member 11, and even if it is temporarily fixed, Only at least one of the upper surface and the lower surface of the auxiliary material 13 is fixed to the horizontal main material 12.
FIG. 3 shows a state in which the wooden shear wall 1 is shear-deformed, but the horizontal secondary member 13 is not fixed to the horizontal member 12 and the vertical member 11 behind the viscoelastic body 14. The horizontal main material 12 can slide in the horizontal direction without being constrained by the horizontal sub-material 13. As a result, when an in-plane shear force is applied to the wooden shear wall 1, it can be greatly sheared.
On the other hand, the vertical load acting on the horizontal main member 12 is transmitted to the lower horizontal main member 12 via the horizontal auxiliary member 13, so that a large load is not applied to the vertical member 11.

また、壁体内に形成された空洞部と壁面に形成された凹陥部に粘弾性体14を充填しておくことで、木製耐震壁1がせん断変形した際に、大きな履歴エネルギー吸収能力を発揮させることができる(図2参照)。即ち、制震壁として機能させることができる。   Further, by filling the hollow portion formed in the wall and the concave portion formed in the wall surface with the viscoelastic body 14, when the wooden earthquake-resistant wall 1 undergoes shear deformation, a large hysteresis energy absorbing ability is exhibited. (See FIG. 2). That is, it can function as a damping wall.

次に、上記の構造からなる木製耐震壁が取り付けられる木造建築物について説明する。
ここでは、図4に示す組立柱および組立梁を骨組とする木造建築物を対象とする。
Next, a wooden building to which a wooden earthquake resistant wall having the above structure is attached will be described.
Here, the object is a wooden building having an assembly column and an assembly beam shown in FIG.

組立柱2および組立梁3は、上記木製耐震壁1と同じ木質棒状の柱主材21,梁主材31と柱副材22,梁副材32から概略構成されている。   The assembly column 2 and the assembly beam 3 are roughly composed of a wooden rod-like column main member 21, a beam main member 31, a column auxiliary member 22, and a beam auxiliary member 32, which are the same as the wooden earthquake-resistant wall 1.

組立柱2は、直交する二方向(梁間方向および桁行方向)に柱副材22の幅分の間隔をあけて3本ずつ、即ち3×3のマトリックス状に柱主材21を平行配置し、当該柱主材21,21間に、柱主材21の材軸方向から見て柱副材22が格子状(本実施形態では井桁状)となるように、柱副材22を2本ずつ直交する方向に交互に積層して配置し、釘や接着剤などで一体に組み立てる。また、上下方向に並んだ柱副材22,22間に、柱副材22と断面形状を同じくする木質棒状の補剛材23を介装する。   The assembly pillars 2 are arranged in parallel in two orthogonal directions (inter-beam direction and cross-beam direction), with three columns at intervals of the width of the column sub-material 22, that is, a 3 × 3 matrix. Between the column main members 21 and 21, the column sub-materials 22 are orthogonal to each other so that the column sub-materials 22 have a lattice shape (in this embodiment, a cross-girder shape) when viewed from the material axis direction of the column main material 21 Laminate them alternately in the direction to be assembled and assemble them together with nails or adhesives. Further, a wooden rod-shaped stiffener 23 having the same cross-sectional shape as that of the column auxiliary member 22 is interposed between the column auxiliary members 22 arranged in the vertical direction.

組立梁3も組立柱2と同様に、直交する二方向(鉛直方向および梁間方向もしくは桁行方向)に梁副材32の幅分の間隔をあけて3本ずつ梁主材31を平行配置する。そして、当該梁主材31,31間に、梁主材31の材軸方向から見て梁副材32が格子状(本実施形態では井桁状)となるように、梁副材32を2本ずつ直交する方向に交互に積層して配置し、釘や接着剤などで一体に組み立て、梁副材32,32間には補剛材33を介装する。   Similarly to the assembly column 2, the assembly beam 3 also has three main beam members 31 arranged in parallel at intervals of the width of the beam sub-material 32 in two orthogonal directions (vertical direction and inter-beam direction or crossing direction). Then, two beam sub-materials 32 are alternately stacked in a direction orthogonal to each other so that the beam sub-materials 32 are in a lattice shape (in this embodiment, a cross-girder shape) when viewed from the material axis direction of the beam main material 31. Are arranged in a single piece with a nail or an adhesive, and a stiffener 33 is interposed between the beam sub-materials 32 and 32.

次に、上記構造からなる組立柱および組立梁を骨組とし、本発明に係る木製耐震壁を備える木造建築物の施工手順について、図5〜図8を用いて説明する。なお、図が煩雑となるため、図5〜図8では、粘弾性体および補剛材に網掛けを施していないが、図1〜図4に記載された粘弾性体および補剛材と変わるものではない。   Next, the construction procedure of the wooden building including the assembly pillar and the assembly beam having the above-described structure and including the wooden earthquake-resistant wall according to the present invention will be described with reference to FIGS. Since the drawings are complicated, in FIGS. 5 to 8, the viscoelastic body and the stiffener are not shaded, but are different from the viscoelastic body and the stiffener described in FIGS. 1 to 4. It is not a thing.

(1)組立梁および組立柱を支持するための基礎コンクリート4を打設する。この際、組立柱が設置される箇所には、柱用金物6を基礎コンクリート4内に埋設しておくとともに、組立梁が設置される基礎コンクリート4の上端部には、梁用金物5を所定の間隔をあけて設置しておく。
(2)梁用金物5内に、組立梁3の下面から下方に突出する梁副材32および補剛材33を挿入して固定するとともに、組立柱2の下端部を柱用金物6に固定する(図5参照)。この際、組立柱2の長さは、施工性を考慮して階高の半分以下に抑え、組立柱2の上端部には柱副材22および補剛材23を設置せず、柱主材21が上方に突出するようにする。また、木製耐震壁が接合される組立梁3の上部には補剛材33を介装しないようにする。
なお、基礎コンクリート4と組立梁3との間には、シート状のゴム材7を介装しておく。これにより、基礎コンクリート4と組立梁3との間に隙間が形成され、換気口として機能する。
(3)梁用金物5の張出し部を利用して床パネル8を構築する(図5参照)。床パネル8は、対向する一対の外部パネル81,81と、当該外部パネル81,81間に配される内部パネル82と、内部パネル82と各外部パネル81との間にそれぞれ形成される断熱部83とから構成されており、内部パネル82、外部パネル81、および断熱部83の厚さは、それぞれ柱副材22および梁副材32の幅と同じになっている。
(1) The foundation concrete 4 for supporting the assembly beam and the assembly column is placed. At this time, the column hardware 6 is buried in the foundation concrete 4 at the place where the assembly pillar is installed, and the beam hardware 5 is set at the upper end of the foundation concrete 4 where the assembly beam is installed. Install with a gap of.

At this time, the length of the assembly column 2 is suppressed to less than half of the floor height in consideration of the workability, and the column main material 22 and the stiffener 23 are not installed at the upper end portion of the assembly column 2, 21 protrudes upward. Further, the stiffener 33 is not interposed above the assembly beam 3 to which the wooden seismic wall is joined.
A sheet-like rubber material 7 is interposed between the basic concrete 4 and the assembly beam 3. Thereby, a clearance gap is formed between the foundation concrete 4 and the assembly beam 3, and functions as a ventilation opening.
(3) The floor panel 8 is constructed using the overhanging portion of the beam hardware 5 (see FIG. 5). The floor panel 8 includes a pair of opposed outer panels 81, 81, an inner panel 82 disposed between the outer panels 81, 81, and a heat insulating portion formed between the inner panel 82 and each outer panel 81. 83, and the thicknesses of the inner panel 82, the outer panel 81, and the heat insulating portion 83 are the same as the widths of the column auxiliary member 22 and the beam auxiliary member 32, respectively.

(4)基礎コンクリート4上に設置された組立柱2の上端部に、組立柱2aを接合する(図6参照)。この際、組立柱2aの下端部は、柱副材22および補剛材23が組立柱2aの下端面から突出するようにしておき、組立柱2の柱主材21,21間に、組立柱2aの柱副材22および補剛材23を挿入して組立柱2,2a同士を接合する。 (4) The assembly pillar 2a is joined to the upper end part of the assembly pillar 2 installed on the foundation concrete 4 (refer FIG. 6). At this time, the lower end portion of the assembly column 2a is such that the column sub-material 22 and the stiffener 23 protrude from the lower end surface of the assembly column 2a, and the assembly column 2 is between the column main members 21 and 21. The column sub-material 22 and the stiffener 23 of 2a are inserted, and the assembly columns 2 and 2a are joined.

(5)組立柱2,2aの側面から側方に突出している柱副材22および補剛材23を、木製耐震壁1の側端部17に挿入させた状態(平面視で側方に突出する水平主材12,12間に柱副材22および補剛材23を挿入した状態)で、木製耐震壁1を上方から落とし込んで組立梁3上にセットする。この際、木製耐震壁1の下端部16については、組立梁3の上面から上方に突出する梁副材32,32間に鉛直材11を挿入する(図7参照)。 (5) A state in which the column auxiliary members 22 and the stiffeners 23 protruding sideways from the side surfaces of the assembly columns 2 and 2a are inserted into the side end portions 17 of the wooden seismic wall 1 (projecting sideways in plan view) With the column sub-material 22 and the stiffener 23 inserted between the horizontal main members 12, 12, the wooden seismic wall 1 is dropped from above and set on the assembly beam 3. At this time, for the lower end portion 16 of the wooden seismic wall 1, the vertical member 11 is inserted between the beam sub-materials 32, 32 protruding upward from the upper surface of the assembly beam 3 (see FIG. 7).

(6)2階の組立梁3aの下面から下方に突出している梁副材32を、木製耐震壁1の上端部17の鉛直材11,11間に挿入してセットする(図8参照)。なお、組立梁3aの上下面から上下方向に突出している梁副材32,32間には補剛材33を介装しないようにする。 (6) The beam secondary member 32 protruding downward from the lower surface of the assembly beam 3a on the second floor is inserted and set between the vertical members 11 and 11 of the upper end portion 17 of the wooden seismic wall 1 (see FIG. 8). Note that the stiffener 33 is not interposed between the beam sub-materials 32 and 32 protruding in the vertical direction from the upper and lower surfaces of the assembly beam 3a.

本発明では、断面形状を同じくする複数の棒材を用いて木製耐震壁1を構成しているので、安価な辺材を利用することができ、材料費を低く抑えることができる。また、同断面の棒材を格子状に組み合わせるだけなので熟練技術を必要とせず、施工が容易である。加えて、水平副材13の上面または下面の少なくとも一方が水平主材12に固着されていないので、木製耐震壁1に面内せん断力が作用した際に、水平副材13が水平主材12の動きを拘束せず、大きなせん断変形能力を発揮することができる。   In this invention, since the wooden earthquake-resistant wall 1 is comprised using the some bar material which has the same cross-sectional shape, an inexpensive slab can be utilized and material cost can be restrained low. In addition, since the rods having the same cross section are simply combined in a lattice shape, no skill is required and construction is easy. In addition, since at least one of the upper surface or the lower surface of the horizontal secondary material 13 is not fixed to the horizontal main material 12, the horizontal secondary material 13 becomes the horizontal main material 12 when an in-plane shear force acts on the wooden seismic wall 1. It is possible to exert a large shear deformation ability without restricting the movement of the.

以上、本発明の実施形態について説明したが、本発明は上記の実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。例えば、上記の実施形態では、木造建築物の柱および梁はそれぞれ組立柱および組立梁としたが、一般に使用されている一本物の角材からなる柱および梁でもよい。また、上記の実施形態では、壁体内に形成された空洞部と壁面に形成された凹陥部に粘弾性体を充填したが、ゴムなどでも良いし、あるいは何も充填しなくても良い。さらにまた、上記の実施形態では、木製耐震壁を構成する棒材を正方形断面としたが、矩形断面でもよい。要は、本発明において所期の機能が得られればよいのである。   Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit thereof. For example, in the above embodiment, the pillars and beams of the wooden building are the assembly pillars and the assembly beams, respectively, but may be pillars and beams made of a single square member that are generally used. In the above embodiment, the hollow portion formed in the wall and the concave portion formed in the wall are filled with the viscoelastic body, but rubber or the like may be filled, or nothing may be filled.
