先行技術を用いた四枚の床版の角部の接合構造では、角部に作用する引張力は処理されるが、せん断力の処理に関しては改善の余地があった。 In the joint structure of the corners of the four decks using the prior art, the tensile force acting on the corners is processed, but there is room for improvement in the treatment of the shear force.

本発明は、上記事実を鑑み、梁上で接合された木質版の角部に作用する引張力及びせん断力の両方を処理する木質版の接合構造を提供することが目的である。 In view of the above facts, it is an object of the present invention to provide a joined structure of a wood slab that treats both a tensile force and a shearing force acting on the corners of the wood slab joined on the beam.

第一態様は、角部が面取りされた木質版と、面取りされた面取面から突出する第一突出部と、複数の前記木質版の前記角部を支持する梁と、前記梁の上面から突出する第二突出部と、複数の前記面取面で囲まれた囲部に充填材が充填されることで形成され、前記第一突出部及び前記第二突出部が埋設された接合部と、を備えた木質版の接合構造である。 The first aspect is from a wood slab with chamfered corners, a first protrusion protruding from the chamfered chamfered surface, a beam supporting the corners of the plurality of wood slabs, and an upper surface of the beam. A second protruding portion that protrudes, and a joint portion that is formed by filling a surrounding portion surrounded by a plurality of chamfered surfaces with a filler and in which the first protruding portion and the second protruding portion are embedded. It is a joint structure of a wood slab equipped with.

第一態様の木質版の接合構造では、梁に支持された複数の木質版の角部の面取面で囲まれた囲部に充填材が充填されることで形成された接合部に、面取面から突出する第一突出部と、梁の上面から突出する第二突出部と、が埋設している。また、複数の木質版の角部は、第一突出部及び接合部（充填材）を介して、互いに接合され、且つ第二突出部及び接合部を介して梁と接合され、一体化している。したがって、木質版の角部に作用する引張力及びせん断力の両方が、効果的に処理される。 In the joint structure of the wood slab of the first aspect, the joint portion formed by filling the surrounding portion surrounded by the chamfered surface of the corners of the plurality of wood slabs supported by the beam with the filler has a surface. A first protrusion protruding from the surface and a second protrusion protruding from the upper surface of the beam are embedded. Further, the corners of the plurality of wood slabs are joined to each other via the first protrusion and the joint (filler), and are joined to the beam via the second protrusion and the joint to be integrated. .. Therefore, both the tensile and shear forces acting on the corners of the wood slab are effectively treated.

第二態様は、前記第一突出部同士は、連結材で連結されている、第一態様に記載の木質版の接合構造である。 The second aspect is the joint structure of the wood slab according to the first aspect , in which the first protrusions are connected to each other by a connecting material.

第二態様の木質版の接合構造では、第一突出部同士は連結材で連結されている。よって、木質版の角部に作用する引張力を木質版が互いに負担し合うので、引張力が更に効果的に処理される。 In the joint structure of the wood slab of the second aspect , the first protrusions are connected to each other by a connecting material. Therefore, since the wood slabs bear each other's tensile force acting on the corners of the wood slab, the tensile force is processed more effectively.

It has a plate material joined to a rod-shaped member, and the first protruding portion is a joint structure of a wood slab according to the first aspect or the second aspect, which protrudes from the plate material.

第三態様の木質版の接合構造では、挿入穴には、拡張部が設けられており、拡張部に充填された充填材が、挿入穴から棒状部材を引き抜く引抜力に抵抗する抵抗要素として機能する。これにより、木質版の面取面と、第一突出部が突出する板材と、の固定強度が高められ、木質版の角部と接合部（充填材）との接合強度が高められる。したがって、木質版の角部に作用する引張力及びせん断力の両方が更に効果的に処理される。 In the joint structure of the wood slab of the third aspect , the insertion hole is provided with an expansion portion, and the filler filled in the expansion portion functions as a resistance element that resists the pulling force of pulling out the rod-shaped member from the insertion hole. do. As a result, the fixing strength between the chamfered surface of the wood slab and the plate material on which the first protrusion protrudes is increased, and the joint strength between the corner portion of the wood slab and the joint portion (filler) is increased. Therefore, both the tensile and shear forces acting on the corners of the wood slab are treated more effectively.

本発明によれば、梁上で接合された木質版の角部に作用する引張力及びせん断力の両方を処理することができる。 According to the present invention, it is possible to treat both the tensile force and the shear force acting on the corners of the wood slab joined on the beam.

The joining member 70 includes a plate member 72, a stud 74 as an example of the first protruding portion, and a rod-shaped member 76. A stud 74 is joined to the outer surface 72A of the plate material 72, and a rod-shaped member 76 is joined to the back surface 72B. The stud 74 projects in a direction orthogonal to the chamfered surface 62.

木質版５０の角部６０には、面取面６２に開口する挿入穴８０が形成され、この挿入穴８０には、複数の拡張部８２が形成されている。接合部材７０の板材７２は、裏面７２Ｂが面取面６２に当接すると共に、棒状部材７６が挿入穴８０に挿入されている。挿入穴８０には充填材８６（図１及び図３参照）が充填されている。そして、充填材８６（図１及び図３参照）が硬化することで棒状部材７６が挿入穴８０に固定され、これにより接合部材７０が木質版５０の角部６０の面取面６２に固定されている。なお、挿入穴８０には、拡張部８２が形成されていなくてもよい。 An insertion hole 80 that opens into the chamfered surface 62 is formed in the corner portion 60 of the wood slab 50, and a plurality of expansion portions 82 are formed in the insertion hole 80. In the plate material 72 of the joining member 70, the back surface 72B abuts on the chamfered surface 62, and the rod-shaped member 76 is inserted into the insertion hole 80. The insertion hole 80 is filled with a filler 86 (see FIGS. 1 and 3). Then, as the filler 86 (see FIGS. 1 and 3) is cured, the rod-shaped member 76 is fixed to the insertion hole 80, whereby the joining member 70 is fixed to the chamfered surface 62 of the corner portion 60 of the wood slab 50. ing. The expansion portion 82 may not be formed in the insertion hole 80.

［作用及び効果］
次に、本実施形態の作用及び効果について説明する。 [Action and effect]
Next, the operation and effect of this embodiment will be described.

本実施形態の合成スラブ１０は、木質版５０の上面５０Ａに鉄筋コンクリート版２０が設けられているので、鉄筋コンクリートのみで構成されたスラブよりも軽量化されると共に、木質版５０のみで構成されたスラブよりも耐火性能及び防音性能が向上する。 Since the reinforced concrete slab 20 is provided on the upper surface 50A of the wood slab 50, the synthetic slab 10 of the present embodiment is lighter than the slab made of only reinforced concrete and is made of only the wood slab 50. Fire resistance and soundproofing performance are improved.

また、梁１２に支持された複数（本実施形態では四枚）の木質版５０の角部６０の面取面６２で囲まれた囲部３０に充填材３２が充填され硬化することで形成された接合部３４に、面取面６２に接合された接合部材７０のスタッド７４と、梁１２の上面１２Ａから突出するスタッド１６と、が埋設している。また、木質版５０の角部６０は、スタッド７４及び接合部３４を介して、互いに接合され、且つスタッド１６及び接合部３４を介して梁１２と接合され、一体化している。したがって、木質版５０の角部６０に作用する引張力及びせん断力の両方が、効果的に処理される。 Further, it is formed by filling and hardening the filler 32 in the surrounding portion 30 surrounded by the chamfered surface 62 of the corner 60 of the wood slab 50 supported by the beam 12 (four in the present embodiment). The stud 74 of the joining member 70 joined to the chamfered surface 62 and the stud 16 protruding from the upper surface 12A of the beam 12 are embedded in the joining portion 34. Further, the corners 60 of the wood slab 50 are joined to each other via the stud 74 and the joint portion 34, and are joined to the beam 12 via the stud 16 and the joint portion 34 to be integrated. Therefore, both the tensile force and the shearing force acting on the corner 60 of the wood slab 50 are effectively processed.

また、挿入穴８０には、拡張部８２が設けられており、拡張部８２に充填され硬化した充填材８６が、挿入穴８０から棒状部材７６を引き抜く引抜力に抵抗する抵抗要素として機能する。これにより、木質版５０の面取面６２と、スタッド７４が突出する板材７２との固定強度が高められ、また、木質版５０の角部６０と接合部３４との接合強度が高められる。したがって、木質版５０の角部６０に作用する引張力及びせん断力の両方が更に効果的に処理される。 Further, the insertion hole 80 is provided with an expansion portion 82, and the filler 86 filled and cured in the expansion portion 82 functions as a resistance element that resists the pulling force of pulling out the rod-shaped member 76 from the insertion hole 80. As a result, the fixing strength between the chamfered surface 62 of the wood slab 50 and the plate material 72 on which the stud 74 protrudes is increased, and the joint strength between the corner portion 60 of the wood slab 50 and the joint portion 34 is increased. Therefore, both the tensile force and the shearing force acting on the corner 60 of the wood slab 50 are more effectively processed.

また、梁１２に支持された複数（本実施形態では四枚）の木質版５０の角部６０の面取面６２で囲まれた囲部３０に充填材３２が充填され硬化することで形成された接合部３４に、面取面６２に接合された接合部材１７０の板状突出部１７４と、梁１２の上面１２Ａから突出するスタッド１６と、が埋設している。また、木質版５０の角部６０は、板状突出部１７４及び接合部３４を介して、互いに接合され、且つスタッド１６及び接合部３４を介して梁１２と接合され、一体化している。したがって、木質版５０の角部６０に作用する引張力及びせん断力の両方が、効果的に処理される。 Further, it is formed by filling and hardening the filler 32 in the surrounding portion 30 surrounded by the chamfered surface 62 of the corner 60 of the wood slab 50 supported by the beam 12 (four in the present embodiment). A plate-shaped protruding portion 174 of the joining member 170 joined to the chamfered surface 62 and a stud 16 protruding from the upper surface 12A of the beam 12 are embedded in the joint portion 34. Further, the corners 60 of the wood slab 50 are joined to each other via the plate-shaped protrusion 174 and the joint portion 34, and are joined to the beam 12 via the stud 16 and the joint portion 34 to be integrated. Therefore, both the tensile force and the shearing force acting on the corner 60 of the wood slab 50 are effectively processed.

更に、木質版５０の角部６０の面取面６２に固定された接合部材１７０の板状突出部１７４同士は連結板１９０で連結されている。よって、木質版５０の角部６０に作用する引張力を木質版５０同士が互いに負担し合うので、引張力が更に効果的に処理される。 Further, the plate-shaped protrusions 174 of the joining member 170 fixed to the chamfered surface 62 of the corner 60 of the wood slab 50 are connected to each other by the connecting plate 190. Therefore, since the wood slabs 50 bear each other's tensile force acting on the corners 60 of the wood slab 50, the tensile force is processed more effectively.

＜その他＞
尚、本発明は上記実施形態に限定されない。 <Others>
The present invention is not limited to the above embodiment.

例えば、上記第一実施形態の接合部材７０及び第二実施形態の接合部材１７０は、木質版５０の角部６０の面取面６２に当接する板材７２、１７２を有していたが、これに限定されない。板材７２、１７２がなく、スタッド７４や板状突出部１７４等の第一突出部が面取面６２から突出する構成であってもよい。例えば、スタッドの頭部及び軸部の一部が露出するように角部６０にねじ込む等して埋設させてもよい。 For example, the joining member 70 of the first embodiment and the joining member 170 of the second embodiment have plate members 72 and 172 that come into contact with the chamfered surface 62 of the corner portion 60 of the wood slab 50. Not limited. There may be no plate members 72 and 172, and the first projecting portion such as the stud 74 or the plate-shaped projecting portion 174 may be configured to project from the chamfered surface 62. For example, it may be embedded by screwing it into the corner portion 60 so that the head portion and a part of the shaft portion of the stud are exposed.

また、例えば、上記実施形態では、合成スラブ１０、１１の木質版５０は、直交集成材で構成されているが、これに限定されない。例えば、単板の繊維方向を揃えて積層し接着した単板積層材（ＬＶＬ（Ｌａｍｉｎａｔｅｄ Ｖｅｎｅｅｒ Ｌｕｍｂｅｒ））であってもよいし、無垢材であってもよい。 Further, for example, in the above embodiment, the wood slabs 50 of the synthetic slabs 10 and 11 are composed of orthogonal laminated lumber, but are not limited thereto. For example, it may be a veneer laminated material (LVL (Laminated Veneer Lumber)) that is laminated and bonded by aligning the fiber directions of the veneer, or may be a solid wood.

また、上記実施形態では、木質版５０の上に鉄筋コンクリート版２０を接合した合成スラブ１０、１１であったが、これに限定されない。木質版５０のみでスラブが構成されていてもよい。 Further, in the above embodiment, the synthetic slabs 10 and 11 in which the reinforced concrete slab 20 is joined on the wood slab 50 are not limited thereto. The slab may be composed of only the wood plate 50.

また、上述の二つの実施形態は、適宜、組み合わされて実施可能である。例えば、第二実施形態の接合部材１７０の板材１７２に第一実施形態の棒状部材７６が接合され面取面６２に固定されてもよい。更に、本発明の要旨を逸脱しない範囲において種々なる態様で実施し得る。 Moreover, the above-mentioned two embodiments can be carried out in combination as appropriate. For example, the rod-shaped member 76 of the first embodiment may be joined to the plate member 172 of the joining member 170 of the second embodiment and fixed to the chamfered surface 62. Further, it can be carried out in various embodiments without departing from the gist of the present invention.
