Description

本願発明は、鋼材と木質材とを組み合わせてなる梁と、凹部を有する柱と、の結合構造に関するものである。 The present invention relates to a coupling structure of a beam formed by combining steel and wood and a column having a recess.

従来から、特開２００５−２３８２５７号公報（特許文献１）に示されるような梁は知られている。 Conventionally, a beam as shown in JP-A-2005-238257 (Patent Document 1) is known.

この種の梁は一般的に図５に示すように、Ｈ型鋼２のフランジ９の外側面にフランジ９と同形の木質材３を設けると共にフランジ９の外側面に木質材３を貫通させてピン４を突設している。そして、管状の柱６と直交方向に結合される。例えば、柱６は円管状で金属からなり、柱６の端部付近の中空内部に円盤７を設け、この円盤７の中央部を開口させて凹部８を設けている。この柱６の凹部８に梁１のピン４を嵌入することで梁１と柱６を直行方向に結合させる。
特開２００５−２３８２５７号公報 As shown in FIG. 5, this type of beam is generally provided with a wood material 3 having the same shape as the flange 9 on the outer surface of the flange 9 of the H-shaped steel 2 and the wood material 3 penetrating through the outer surface of the flange 9. 4 is protruding. And it couple | bonds with the tubular pillar 6 in the orthogonal direction. For example, the column 6 is made of metal with a tubular shape, and a disk 7 is provided in a hollow interior near the end of the column 6, and a concave portion 8 is provided by opening the center of the disk 7. By inserting the pin 4 of the beam 1 into the recess 8 of the column 6, the beam 1 and the column 6 are coupled in the orthogonal direction.
JP 2005-238257 A

しかしながら、特開２００５−２３８２５７号公報に示される上記従来例の梁１にあっては、ピン４と円盤７の凹部８との間に隙間があると、柱６に筋交い等を施工する際に柱６が梁１に対して回転しやすくなる。よって、梁１と柱６の結合構造が不安定になるので、柱６を釘２０で固定する必要があった。これにより、施工時間が多く必要になるという問題が生じていた。 However, in the conventional beam 1 shown in Japanese Patent Application Laid-Open No. 2005-238257, if there is a gap between the pin 4 and the concave portion 8 of the disk 7, The column 6 is easy to rotate with respect to the beam 1. Therefore, since the coupling structure of the beam 1 and the column 6 becomes unstable, it is necessary to fix the column 6 with the nail 20. Thereby, the problem that much construction time is needed has arisen.

本願発明は上記背景技術に鑑みて発明されたものであり、その課題は、柱の回転を防止して施工時間を短縮できる梁と柱の結合構造を提供することである。 This invention is invented in view of the said background art, The subject is preventing the rotation of a pillar and providing the coupling | bonding structure of a beam and a pillar which can shorten construction time.

上記課題を解決するために、本願請求項１記載の発明では、端部に凹部を有する柱と、Ｈ型鋼のフランジの外側面にフランジと同形の木質材を設けると共にフランジの外側面に木質材を貫通させてピンを突設し、木質材表面のピンの周囲に柱の端部外周形状と対応する形状の凹所を形成した梁と、を備え、柱の凹部に梁のピンが嵌入されると共に梁の凹所に柱の端部が圧入保持されることで、梁と柱とが略直交方向に結合されるようにしている。 In order to solve the above-mentioned problem, in the invention according to claim 1 of the present application, a pillar having a recess at the end, a wood material having the same shape as the flange is provided on the outer surface of the flange of the H-shaped steel, and the wood material is provided on the outer surface of the flange. And a beam having a recess with a shape corresponding to the outer peripheral shape of the column end around the pin on the surface of the wood material, and the beam pin is inserted into the column recess In addition, the end of the column is press-fitted and held in the recess of the beam so that the beam and the column are coupled in a substantially orthogonal direction.

又、本願請求項２記載の発明では、上記請求項１記載の梁と柱の結合構造において、梁の凹所内周径が柱の端部外周径よりも小さく形成されることで、梁の凹所に柱の端部が圧入保持されるようにしたことを特徴としている。 Further, in the invention according to claim 2 of the present application, in the coupled structure of the beam and the column according to claim 1 described above, the inner diameter of the recess of the beam is formed smaller than the outer diameter of the end of the column. It is characterized in that the end of the pillar is press-fitted and held at the place.

本願請求項１記載の発明の梁と柱の結合構造においては、木質材表面のピンの周囲に柱の端部外周形状と対応する形状の凹所が形成され、この凹所に柱の端部が圧入保持されるので、柱の端部が凹所内で締め付けられるように保持され、回転する恐れを軽減することができる。 In the coupled structure of the beam and the column according to the first aspect of the present invention, a recess having a shape corresponding to the outer peripheral shape of the column end is formed around the pin on the surface of the wooden material, and the column end is formed in this recess Is press-fitted and held, so that the end of the pillar is held so as to be tightened in the recess, and the possibility of rotating can be reduced.

本願請求項２記載の発明の梁と柱の結合構造においては、特に、梁の凹所内周径が柱の端部外周径よりも小さく形成されているため、柱の端部は凹所内で確実に締め付けられるように保持されることになり、柱が回転する恐れを更に軽減することができる。 In the coupled structure of the beam and the column of the invention according to claim 2 of the present application, in particular, since the inner diameter of the recess of the beam is smaller than the outer diameter of the end of the column, the end of the column is surely secured in the recess. Therefore, it is possible to further reduce the possibility that the column rotates.

以下、本願発明を添付図面に示す実施形態に基づいて説明する。 Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

図１〜４は本願請求項１、２全てに対応した一実施形態である梁１と柱６の結合構造を示している。 1 to 4 show a coupling structure of a beam 1 and a column 6 which is an embodiment corresponding to all of claims 1 and 2 of the present application.

この梁１と柱６の結合構造は、端部に凹部８を有する柱６と、Ｈ型鋼２のフランジ９の外側面にフランジ９と同形の木質材３を設けると共にフランジ９の外側面に木質材３を貫通させてピン４を突設し、木質材３表面のピン４の周囲に柱６の端部外周形状と対応する形状の凹所５を形成した梁１と、を備え、柱６の凹部８に梁１のピン４が嵌入されると共に梁１の凹所５に柱６の端部が圧入保持されることで、梁１と柱６とが略直交方向に結合されるようにしている。そして、梁１の凹所５内周径が柱６の端部外周径よりも小さく形成されることで、梁１の凹所５に柱６の端部が圧入保持されるようにしている。 The beam 1 and the column 6 are connected to each other by providing a column 6 having a recess 8 at the end, a wooden material 3 having the same shape as the flange 9 on the outer surface of the flange 9 of the H-shaped steel 2 and a wooden material on the outer surface of the flange 9. A beam 4 having a pin 4 projecting through the material 3 and having a recess 5 having a shape corresponding to the outer peripheral shape of the end of the column 6 around the pin 4 on the surface of the wood material 3; The pin 4 of the beam 1 is inserted into the recess 8 and the end of the column 6 is press-fitted and held in the recess 5 of the beam 1 so that the beam 1 and the column 6 are coupled in a substantially orthogonal direction. ing. The inner diameter of the recess 5 of the beam 1 is smaller than the outer diameter of the end of the column 6, so that the end of the column 6 is press-fitted and held in the recess 5 of the beam 1.

以下、この実施形態の梁１と柱６の結合構造をより具体的詳細に説明する。 Hereinafter, the coupling structure of the beam 1 and the column 6 of this embodiment will be described in more detail.

柱６は円管状の金属からなり、柱６の端部付近の中空内部に金属の円盤７を溶接して設け、この円盤７の中央部を開口させて円状の凹部８を設けている。 The column 6 is made of a tubular metal, and a metal disk 7 is welded to a hollow interior near the end of the column 6, and a circular recess 8 is formed by opening the center of the disk 7.

梁１はＨ型鋼２の上下のフランジ（９ａ、９ｂ）の外側面にフランジ９（９ａ、９ｂ）と同形の木質材３を設けてなり、Ｈ型鋼２の上フランジ９ａには図示していないが固定用ピンが溶接して設けられ、この固定用ピンは木質材３に穿たれた貫入孔に貫入、固定される。Ｈ型鋼２の下フランジ９ｂには図示していないが梁１を構造材あるいは躯体に固定するための釘孔が設けられている。上フランジ９ａの外側面には木質材３を貫通させて金属からなる円柱状のピン４を溶接して突設している。そして、木質材３表面のピン４の周囲には柱６の端部外周形状と対応する形状の凹所５を形成している。この凹所５の内周径は柱６の端部外周径よりもやや小さく形成されている。 The beam 1 is provided with a wood material 3 having the same shape as the flange 9 (9a, 9b) on the outer surface of the upper and lower flanges (9a, 9b) of the H-shaped steel 2 and is not shown in the upper flange 9a of the H-shaped steel 2 A fixing pin is provided by welding, and this fixing pin is inserted into and fixed to a penetration hole formed in the wood material 3. Although not shown, the lower flange 9b of the H-shaped steel 2 is provided with a nail hole for fixing the beam 1 to a structural material or a frame. A cylindrical pin 4 made of metal is welded and protruded from the outer surface of the upper flange 9a through the wood material 3. A recess 5 having a shape corresponding to the outer peripheral shape of the end of the column 6 is formed around the pin 4 on the surface of the wooden material 3. The inner peripheral diameter of the recess 5 is slightly smaller than the outer peripheral diameter of the end portion of the column 6.

この柱６と梁１は、柱６の凹部８に梁１のピン４が嵌入されると共に梁１の凹所５に柱６の端部が圧入保持されることで、梁１と柱６とが略直交方向に結合される。 In this column 6 and beam 1, the pin 4 of the beam 1 is fitted in the recess 8 of the column 6 and the end of the column 6 is press-fitted and held in the recess 5 of the beam 1. Are coupled in a substantially orthogonal direction.

したがって、この実施形態の梁１と柱６の結合構造においては、木質材３表面のピン４の周囲に柱６の端部外周形状と対応する形状の凹所５が形成され、この凹所５に柱６の端部が圧入保持されるので、柱６の端部が凹所５内で締め付けられるように保持され、回転する恐れを軽減することができる。 Therefore, in the coupling structure of the beam 1 and the column 6 of this embodiment, the recess 5 having a shape corresponding to the outer peripheral shape of the end of the column 6 is formed around the pin 4 on the surface of the wooden material 3. Since the end of the column 6 is press-fitted and held, the end of the column 6 is held so as to be tightened in the recess 5, and the possibility of rotating can be reduced.

又、梁１の凹所５内周径が柱６の端部外周径よりも小さく形成されているため、柱６の端部は凹所５内で確実に締め付けられるように保持されることになり、柱６が回転する恐れを更に軽減することができる。 Further, since the inner peripheral diameter of the recess 5 of the beam 1 is smaller than the outer peripheral diameter of the end of the column 6, the end of the column 6 is held so as to be securely tightened in the recess 5. Thus, the possibility that the pillar 6 rotates can be further reduced.

又、柱６は円管状であるため、組立て時において使用者が柱６を持ちやすくなる共に誤って人や物が柱６にぶつかることがあっても傷つく恐れを軽減できる。 In addition, since the pillar 6 has a circular tube shape, the user can easily hold the pillar 6 at the time of assembling, and the possibility of being damaged even if a person or an object hits the pillar 6 by mistake can be reduced.

なお、本実施形態において柱６は円管状であるが、この形状に限定するものではなく、角管状などであってもよい。 In addition, in this embodiment, although the pillar 6 is circular tube shape, it is not limited to this shape, A square tube etc. may be sufficient.
