Description

本願発明は、主に木材で構造躯体を構築する建築物で、梁の側面に他の梁の端縁を対向させて接合する梁の接合構造に係り、特に木製梁と鋼製梁とを接合する構造に関するものである。   The present invention relates to a structure of a structure in which a structural frame is mainly constructed of wood, and relates to a bonded structure in which the edge of another beam is opposed to the side of the beam, and in particular, a wooden beam and a steel beam are bonded. It is related to the structure.

木造建築物における梁と梁との接合構造として古くから一般に普及している工法では、受梁に切り欠きを設けるとともに、掛け合わせる梁に上記切り欠きに嵌め合わせられる仕口を施している。このような接合構造では,双方の梁に切削加工を施すために、高度の技術が必要となり、加工のための費用も嵩むことになる。このような事情から近年では梁と梁との接合部に金物を用い、部材の加工を少なくするともに、現場において容易に接合が可能な接合構造が提案されている。   In a construction method that has been widely used for a long time as a joint structure between beams in a wooden building, a notch is provided in a receiving beam, and a joint that is fitted into the notch is applied to a beam to be crossed. In such a joint structure, in order to cut both beams, a high level of technology is required, and the cost for processing increases. In recent years, a joint structure has been proposed in which metal is used for the joint between the beams to reduce the processing of the members and can be easily joined in the field.

例えば、特許文献1に図17に示すような梁の接合構造が記載されている。
この接合構造は、第1の木製梁121の側面に第2の木製梁122の端面を突き当てて接合するものであり、第1の木製梁に鉛直孔121aを穿設する。この孔に螺旋状の張り出し部を有する第1のスクリュー部材131をねじ込む。第1のスクリュー部材には、軸線と直角方向にねじ穴131aが設けられており、第1の木製梁121の側面から第1のスクリュー部材131に向かう横穴121bにボルト134を挿通する。このボルト134をねじ孔131aに螺合することよって第1の木製梁121の側面に梁接合金具133を固定する。一方、第2の木製梁122の端部にも第2のスクリュー部材132をねじ込み、第2の木製梁122及び第2のスクリュー部材132を貫通するピン135を梁接合金具に設けられた穴133aに挿通する。これによって第2の木製梁122を上記梁接合金具133と連結するものである。このような接合構造では、スクリュー部材131,132および梁接合金具133を介して、大きな鉛直方向の力が双方の梁間で円滑に伝達される。また、梁の高さの全域にわたって鉛直方向の力が伝達され、局部的に応力が集中することが防止されるものとなっている。
特開2004−92149号公報
For example, Patent Document 1 describes a beam joining structure as shown in FIG.
In this joining structure, the end face of the second wooden beam 122 is abutted against the side face of the first wooden beam 121 and joined, and a vertical hole 121a is formed in the first wooden beam. A first screw member 131 having a spiral projecting portion is screwed into this hole. A screw hole 131 a is provided in the first screw member in a direction perpendicular to the axis, and a bolt 134 is inserted into a lateral hole 121 b that faces the first screw member 131 from the side surface of the first wooden beam 121. The bolt 134 is screwed into the screw hole 131a to fix the beam joint 133 to the side surface of the first wooden beam 121. On the other hand, the second screw member 132 is also screwed into the end portion of the second wooden beam 122, and a pin 133 penetrating the second wooden beam 122 and the second screw member 132 is provided in the hole 133a provided in the beam joining bracket. Insert through. In this way, the second wooden beam 122 is connected to the beam joint metal 133. In such a joint structure, a large vertical force is smoothly transmitted between both beams via the screw members 131 and 132 and the beam joint metal 133. In addition, the force in the vertical direction is transmitted over the entire height of the beam, so that local stress concentration is prevented.
JP 2004-92149 A

近年においては木造の建築物においても屋内に柱の少ない大空間が求められることも多くなっている。また、大きな開口部を設けることが要求されることもある。このような場合には梁の支間が大きくなり、梁に生じる曲げモーメントの値が大きくなる。大きな曲げモーメントに抵抗するためには梁の断面、特に梁の高さを大きくする必要があるが、梁の納まりに支障を生じる場合も生じ、経済的にも現実的ではない。
また、二階が一階より張り出すように設けられる場合がある。このようなときには、梁が片持ち状に張り出し、梁を支持する部分に大きな曲げモーメントが生じる。また、張り出した梁の先端の撓みが大きくなり、経時的に進行するクリープ撓みが問題になる場合もある。
上記のような場合には、主に木材で構造躯体が構築されるいわゆる木造建築物であっても、一部の梁に鋼製の梁を用いるのが合理的で、経済的となることがある。このため、簡単な構造で木製の梁と鋼製の梁とを接合する構造が望まれる。
In recent years, there has been an increasing demand for large spaces with few pillars indoors even in wooden buildings. It may also be required to provide a large opening. In such a case, the span of the beam becomes large, and the value of the bending moment generated in the beam becomes large. In order to resist a large bending moment, it is necessary to increase the cross section of the beam, in particular the height of the beam, but this may cause trouble in the fitting of the beam, which is not economically practical.
In addition, the second floor may be provided so as to protrude from the first floor. In such a case, the beam protrudes in a cantilever manner, and a large bending moment is generated in the portion that supports the beam. Moreover, the bending of the end of the overhanging beam becomes large, and the creep bending that progresses with time may become a problem.
In the above cases, it is reasonable and economical to use steel beams for some of the beams even in the case of so-called wooden buildings where the structural frame is mainly constructed of wood. is there. For this reason, the structure which joins a wooden beam and a steel beam with a simple structure is desired.
