Description

本発明は、基礎または床の上に主にCLT(Cross Laminated Timber)壁パネル等の木質系壁パネルを接合するための木質系壁パネル用接合金物、およびその木質系壁パネル用接合金物を用いた木造建物に関する。   The present invention is directed to a metal-based wall panel joint metal for joining wood-based wall panels such as CLT (Cross Laminated Timber) wall panels mainly on a foundation or floor, and a joint metal-metal joint for the wood-based wall panel. It was about a wooden building.

従来より、木質系壁パネルや床パネル等の木質系パネルから構成される「壁式構造」の木造建物の普及が拡大している。   2. Description of the Related Art Conventionally, the widespread use of "wall-type structure" wooden buildings composed of wood-based panels such as wood-based wall panels and floor panels has been expanding.

このような木質系パネルの一つとして、近年、ひき板(ラミナ)を繊維方向が直交するように積層接着したCLT(Cross Laminated Timber)パネルが採用され始めている(例えば、特許文献1参照。)。このようなCLTパネルでは、ひき板(ラミナ)の繊維の向きが交互に直交するので、各ひき板の膨張及び収縮を抑制可能で寸法の安定性が高くなると共に、壁面で建物を支えるので耐震性が高く、高層化も可能であり、またCLTパネルは厚みがあるので断熱性・遮音性・耐火性が高いといった利点がある。   In recent years, as one of such wood-based panels, a CLT (Cross Laminated Timber) panel in which a laminated plate (lamina) is laminated and bonded so that the fiber directions are orthogonal is beginning to be adopted (see, for example, Patent Document 1). . In such a CLT panel, since the orientation of the fibers of the lamina is alternated at right angles, expansion and contraction of each lamina can be suppressed and dimensional stability is enhanced, and a building is supported by the wall surface, so earthquake resistance The CLT panel has the advantages of high thermal insulation, sound insulation and fire resistance because of its thickness.

しかし、上述の特許文献1に記載の従来技術は、外周に雄ネジ部が形成された金属製の棒状金具と、板状の本体と同本体の基端部又は基端部付近から内方にかけて配設される鋼管からなる棒状金具案内通路と棒状金具案内通路内方側において絞り加工によって小径とされた部分の内部壁面に形成された雄ネジ部と螺合される雌ネジ部とを有する連結金具とによって木質壁パネルを接合する構造であるため、連結金具が木質壁パネルに作用する引張力およびせん断力の双方を負担することになり、効率良く設計できないという問題がある。   However, according to the prior art described in the above-mentioned Patent Document 1, a metal rod fitting having an external thread formed on the outer periphery, a plate-like main body and a proximal end or base end from near the proximal end to the inner side A connection having a rod-shaped fitting guide passage made of steel pipe and an external thread portion formed on an inner wall surface of a portion reduced in diameter by drawing at the inner side of the rod-shaped fitting guide passage. Since the wood wall panel is joined by the metal fitting, the connecting metal fitting bears both the tensile force and the shearing force acting on the wood wall panel, and there is a problem that the design can not be performed efficiently.

特に、連結金具を構成する板状の本体は、棒状金具とは異なり厚さが薄いので、引張力およびせん断力の双方を負担した場合、所定の耐力を確保するためには厚さや面積等を大きく確保する必要が生じ、効率良く設計できない。   In particular, since the plate-like main body constituting the connection fitting is thin unlike the rod-like fitting, the thickness, area, etc. are required to secure a predetermined resistance when both tensile force and shear force are applied. It is necessary to secure a large size, and it is not possible to design efficiently.

そこで、本発明はこのような課題に着目してなされたもので、木質系壁パネルに作用する引張力とせん断力とを独立した接合金物で主に負担させて各接合金物の耐力を効率良く設計し、木質系壁パネルを耐震壁とした耐震性の高い木造建物を効率良く構築することができる木質系壁パネル用接合金物、およびその木質系壁パネル用接合金物を用いた木造建物を提供することを目的とする。   Therefore, the present invention has been made focusing on such problems, and the tensile force and the shear force acting on the wood-based wall panel are mainly carried by independent bonding hardware, and the yield strength of each bonding hardware is efficiently achieved. Joints for wood-based wall panels that can be efficiently designed to build high seismic resistance wooden buildings with wood-based wall panels as earthquake-resistant walls, and wooden constructions using the joints for wood-based wall panels The purpose is to

(Second joint hardware 2)
As described above, the second bonding hardware 2 is provided between the first bonding hardware 1 on the left and right sides at the lower end of the CLT wall panels P1 and P1 ′, and as shown in FIGS. In the case of constructing a wall, the rectangular fixing plate portion 21 in which four male screw portion insertion holes 21a are formed into which the male screw portion 51a at the tip of the anchor bolt 51 extending from the base BF is inserted The CLT wall panels are erected in the thickness direction of the CLT wall panels P1 and P1 ′, ie, in the center of the short direction of the foundation BF, in the horizontal direction of the CLT wall panels P1 and P1 ′, ie parallel to the longitudinal direction of the foundation BF. A shear force receiving plate portion 22 is inserted into a slit groove or a recessed portion formed in the lower end portion of the panels P1 and P1 ′, which is a seat portion, and a second bonded metal container portion P1c (see FIG. 17) described later. The long side of the fixed plate portion 21 is, for example, 420 mm, and the short side is 120 mm, which is the same as 120 mm which is the thickness of the CLT wall panels P1 and P1 '. The shear force receiving plate portion 22 has, for example, a thickness of 6 mm, a length of 280 mm, and a height of 125 mm. Further, the outer diameter of the anchor bolt 51 for fixing the second joint metal 2 is, for example, 16 mm.

ここで、通常、CLT壁パネルP1,P1’の第2接合金物用収容部P1c(図17参照。)はドリル等を利用して木材に対し加工するため、せん断力受け板部22の正面形状は、せん断力受け板部22が挿入されるCLT壁パネルP1,P1’底面の第2接合金物用収容部P1c(図17参照。)の加工精度も考慮して、底面板21との接合部に近付くほど拡がり、上部にいくに従い窄まるほぼ半円形状に形成されている。   Here, in general, the second joint metal container storage portion P1c (see FIG. 17) of the CLT wall panels P1 and P1 ′ is processed to wood using a drill or the like, so the front shape of the shear force receiving plate portion 22 The joint with the bottom plate 21 is also considered taking into account the processing accuracy of the second joint metal container accommodation portion P1c (see FIG. 17) on the bottom of the CLT wall panel P1, P1 ′ into which the shear force receiving plate 22 is inserted. It spreads as it approaches and is formed in a substantially semicircular shape that narrows toward the upper part.

A positioning pin fitting portion 22b into which a drift pin 53, which is a positioning pin penetrating in the thickness direction of the CLT wall panels P1 and P1 ′, is formed at an intermediate point in the longitudinal direction of the foundation BF 22.

ピン挿通長孔22aを上下方向に長い長孔形状にした理由は、第2接合金物2が主にせん断力を負担し、圧縮力や引張力を負担しないようにするためである。   The reason for making the pin insertion long hole 22a into a long long hole shape in the vertical direction is to make the second bonding metal 2 mainly bear a shearing force and not to bear a compressive force or a tensile force.

位置決めピン嵌合部22bは、位置決めピンであるドリフトピン53が嵌合し易くなるよう、開口側に向かって、すなわち図8(b)上、上方に向かうほど幅がV字形状に広がるガイド部が形成されている。   The positioning pin fitting portion 22b is a guide portion whose width extends in a V-shape toward the opening side, that is, in the upper side in FIG. 8B, so that the drift pin 53 serving as a positioning pin can be easily fitted. Is formed.

<Main Effects of Bonding Material for Wood-Based Wall Panel of Embodiment of Embodiment>
As explained above, in the wooden building using the wood-based wall panel joining hardware and the wood-based wall panel joining hardware of the embodiment according to the present invention, the CLT wall panels P1 and P1 'are provided on the left and right sides of the lower end portion. The first joint metal 1 and the second joint metal 2 provided between the first joint metal 1 at the lower end of the CLT wall panel P1, P1 'and the third joint provided on the left and right sides of the upper end of the CLT wall panel P1, P1' The third joint metal 4 and the fourth joint metal 4 provided between the third joint metal 3 at the upper end of the CLT wall panel P1, P1 ′ are provided to the rod portion 14 and the third joint metal 3 of the first joint metal 1. Drift pins 53 are inserted into each of the plurality of pin insertion long holes 14a and 3a provided at arbitrary intervals in the longitudinal direction, ie, the vertical direction, to mainly bear the tensile force acting on the CLT wall panels P1 and P1 ', Second joint hardware 2 and Drift pins 53 are inserted into the shear force receiving plates 22 and 42 of the metal joint 4 respectively at a plurality of vertically extending long holes 22a and 42a provided at given intervals in the longitudinal direction. It comprised so that the shear force which acts on CLT wall panel P1, P1 'might be mainly paid.

そのため、実施形態の木質系壁パネル用接合金物およびその木質系壁パネル用接合金物を用いた木造建物によれば、引張力を主に負担する第1接合金物1および第3接合金物3と、せん断力を主に負担する第2接合金物2および第4接合金物4とを別の接合金物として独立させたので、引張力負担用の第1接合金物および第3接合金物と、せん断力負担用の第2接合金物および第4接合金物とを効率良く設計することができ、その結果、木質系壁パネルを耐震壁とした耐震性の高い木造建物を効率良く構築することができる。   Therefore, according to the wood-based wall panel joining hardware of the embodiment and the wooden building using the wood-based wall panel joining hardware, the first joint hardware 1 and the third joint hardware 3 mainly carrying tensile force, The second joint metal 2 and the fourth joint metal 4 which mainly bear the shear force are made independent as separate joint metals, so the first joint metal and the third joint metal for tensile force bearing and for the shear force The second joint metal and the fourth joint metal can be efficiently designed, and as a result, it is possible to efficiently construct a high earthquake resistant wooden building in which the wood-based wall panel is a seismic wall.

特に、実施形態の第2接合金物2のせん断力受け板部22と、第4接合金物4のせん断力受け板部42には、それぞれ、上下方向に長孔形状のピン挿通長孔22a,42aを設けたため、地震などによって第2接合金物2および第4接合金物4に対し引抜き力が発生した場合でも、ピン挿通長孔22a,42aによって引抜き力を第2接合金物2および第4接合金物4から逃がすことができるので、第1接合金物1および第3接合金物3に確実に引抜き力を負担させることができる。   In particular, in the shear force receiving plate portion 22 of the second bonding metal 2 of the embodiment and the shear force receiving plate portion 42 of the fourth bonding metal 4, pin insertion long holes 22 a and 42 a having a long hole shape in the vertical direction, respectively. Therefore, even if the second joint metal 2 and the fourth joint metal 4 are pulled out due to an earthquake or the like, the second joint metal 2 and the fourth joint metal 4 are drawn by the pin insertion long holes 22a and 42a. As a result, the first joint hardware 1 and the third joint hardware 3 can be made to bear the pulling force with certainty.

また、実施形態の第2接合金物2のせん断力受け板部22と第4接合金物4のせん断力受け板部42は、その正面形状は、それぞれ、底面板21または円盤状固定板部41との接合部に近付くほど拡がり、上部にいくに従い窄まるほぼ半円形状に形成したため、せん断力受け板部22またはせん断力受け板部42が挿入されるCLT壁パネルP1,P1’底面に形成する第2接合金物用収容部P1c(図17参照。)や第4接合金物用収容部P1e(図20、図23参照。)の加工穴の角がしっかり取れていない場合でも、せん断力受け板部22またはせん断力受け板部42が当たり難くなり、施工性を向上させることができる。   Further, the shear force receiving plate portion 22 of the second bonding metal 2 of the embodiment and the shear force receiving plate portion 42 of the fourth bonding metal 4 have the bottom plate 21 or the disk-like fixing plate 41 and the front shape, respectively. Since it is formed in a substantially semicircular shape that expands as it approaches the joint portion of the lower part and narrows toward the upper part, the shear force receiving plate portion 22 or the shear force receiving plate portion 42 is formed on the bottom of CLT wall panel P1, P1 ' Even if the corner of the processing hole of the second joint metal container storage portion P1c (see FIG. 17) or the fourth joint metal container storage portion P1e (see FIGS. 20 and 23) is not firmly secured, the shear force receiving plate portion 22 or the shear force receiving plate portion 42 becomes difficult to hit, and the workability can be improved.

また、実施形態の木質系壁パネル用接合金物およびその木質系壁パネル用接合金物を用いた木造建物では、第1接合金物1は、棒状部14の下端部には、雌ネジ部14aが形成され、上面板13には連結ボルト15の雄ネジ部15aが挿入される雄ネジ部挿入孔14aが形成されており、棒状部14は、連結ボルト15の雄ネジ部15aが棒状部14の雌ネジ部14aに螺合して上面板13に固定されるように構成されている。   Moreover, in the wooden building using the wood-based wall panel joint metal and the wood-based wall panel joint metal work according to the embodiment, the first joint metal body 1 has a female screw portion 14a formed at the lower end portion of the rod portion 14. The male screw portion insertion hole 14a into which the male screw portion 15a of the connection bolt 15 is inserted is formed in the upper surface plate 13, and in the rod portion 14, the female screw portion 15a of the connection bolt 15 is a female of the rod portion 14 The screw 14 a is configured to be screwed and fixed to the upper surface plate 13.
