そして、構造体１は、コンクリート柱２の内部に配置され、第１木質梁３Ａにおける棒状部材３５の一端部３５Ａと、第２木質梁３Ｂにおける棒状部材３５の一端部３５Ａとを接続する第２定着部材５２を備えていてもよい。
FIG. 4 is a schematic view showing a configuration example of the structure according to the embodiment.
In some embodiments, for example, as shown in FIG. 4, in any of the configurations described above, the wood beam 3 is the first wood beam 3A connected to the one side 2A of the concrete pillar 2 and the concrete pillar 2. The second wooden beam 3B connected to the other side 2B may be included.

It is connected by a second fixing member 52 arranged inside the concrete column 2. Therefore, the first wooden beam 3A and the second wooden beam 3B can be firmly connected, and the connection strength between the wooden beam 3 and the concrete column 2 can be improved. Further, since the second fixing member 52 is arranged inside the concrete column 2, the texture of the wooden beam 3 is not impaired as compared with the case where the second fixing member 52 is arranged outside the concrete column 2, for example. ..
図５は一実施形態に係る構造体の構成例を示す概略図である。幾つかの実施形態では、例えば図５に示すように、上述した何れか一つの構成において、コンクリート柱２は、当該コンクリート柱２のうち木質梁３と対向する面に設けられた凸部２０を含み、木質梁３は、一端面３０Ａ又は他端面３０Ｂに設けられた凹部４０であって、凸部２０に嵌合して木質梁３を係止可能な凹部４０を含んでいてもよい。 FIG. 5 is a schematic view showing a configuration example of a structure according to an embodiment. In some embodiments, for example, as shown in FIG. 5, in any one of the above configurations, the concrete pillar 2 has a convex portion 20 provided on a surface of the concrete pillar 2 facing the wooden beam 3. Including, the wooden beam 3 may include a recess 40 provided in one end surface 30A or the other end surface 30B, and may include a recess 40 that fits into the convex portion 20 and can lock the wooden beam 3.
凸部２０及び凹部４０は、コンクリート柱２と木質梁３とが対向する面に予め形成されており、例えばコッター又はシアキーであってもよい。 The convex portion 20 and the concave portion 40 are formed in advance on the surface where the concrete pillar 2 and the wooden beam 3 face each other, and may be, for example, a cotter or a shear key.
このように凸部２０及び凹部４０を備えた構成によれば、コンクリート柱２に設けられた凸部２０と、木質梁３の端面に設けられた凹部４０とが嵌合することにより、木質梁３をコンクリート柱２に係止することができるから、柱断面を確保しつつ木質梁３とコンクリート柱２との接続強度の向上を図ることができる。 According to the configuration provided with the convex portion 20 and the concave portion 40 in this way, the convex portion 20 provided on the concrete column 2 and the concave portion 40 provided on the end face of the wooden beam 3 are fitted to each other to fit the wooden beam. Since 3 can be locked to the concrete column 2, the connection strength between the wooden beam 3 and the concrete column 2 can be improved while ensuring the column cross section.
いくつかの実施形態では、例えば図５（Ｃ）に示すように、凸部２０は、木質梁３との対向部２８の上端２２及び下端２３とそれぞれ間隔を隔てて突設された凸部２０であってもよい。さらに、凸部２０は、側端２４、２６とそれぞれ間隔を隔てて突設された凸部２０であってもよい。 In some embodiments, for example, as shown in FIG. 5C, the convex portion 20 projects from the upper end 22 and the lower end 23 of the portion 28 facing the wooden beam 3 at intervals. It may be. Further, the convex portion 20 may be a convex portion 20 projecting from the side ends 24 and 26 at intervals.
いくつかの実施形態では、例えば図５（Ａ）に示すように、上述した凸部２０と凹部４０とを備えた構成において、木質梁３の一端面３０Ａ又は他端面３０Ｂにおける挿入部３１の開口部３１Ａは、凹部４０と間隔を隔てて配置されていてもよい。
棒状部材３５は、梁本体３０のうち、長手方向Ｌと交差する一方向において凹部４０又は凸部２０と干渉しないように配置される。
In some embodiments, for example, as shown in FIG. 5A, in the configuration provided with the convex portion 20 and the concave portion 40 described above, the opening of the insertion portion 31 in the one end surface 30A or the other end surface 30B of the wooden beam 3 The portion 31A may be arranged at a distance from the recess 40.
The rod-shaped member 35 is arranged in the beam body 30 so as not to interfere with the concave portion 40 or the convex portion 20 in one direction intersecting the longitudinal direction L.
このように、木質梁３の一端面３０Ａ又は他端面３０Ｂにおける挿入部３１の開口部３１Ａが、コンクリート柱２の凸部２０に嵌合する凹部４０と間隔を隔てて配置された構成によれば、挿入部３１の開口部３１Ａから突出する棒状部材３５がコンクリート柱２の凸部２０に配置されることがない。これにより、柱断面を確保することができるから、コンクリート柱２と木質梁３とを備えた構造体１において、コンクリート柱２と木質梁３との接続強度を向上することができる。 As described above, according to the configuration in which the opening 31A of the insertion portion 31 in the one end surface 30A or the other end surface 30B of the wooden beam 3 is arranged at a distance from the recess 40 fitted in the convex portion 20 of the concrete column 2. The rod-shaped member 35 protruding from the opening 31A of the insertion portion 31 is not arranged on the convex portion 20 of the concrete column 2. As a result, since the cross section of the column can be secured, the connection strength between the concrete column 2 and the wooden beam 3 can be improved in the structure 1 provided with the concrete column 2 and the wooden beam 3.
幾つかの実施形態では、例えば図１に示すように、挿入部３１は、コンクリート柱２に取り付けられる際に上側又は下側を向く梁本体３０の少なくとも一辺側に配置されていてもよい。例えば図１に示す例では、梁本体３０の上辺側のみに挿入部３１が配置されている。このように挿入部３１が配置されることにより、引張力が作用する側に金属製の棒状部材３５を配置することで木質梁３の強度を補強することができる。また、棒状部材３５は、コンクリート柱２に取り付けられる際に上側を向く木質梁３の一辺（例えば上辺）側、及びコンクリート柱２に取り付けられる際に下側を向く木質梁３の他辺（例えば下辺）側に配置されていてもよい。このようにすれば、上下方向及び水平方向(長手方向Ｌ)に対する(引っ張り)強度を向上することができる。 In some embodiments, for example, as shown in FIG. 1, the insertion portion 31 may be arranged on at least one side of the beam body 30 that faces upward or downward when attached to the concrete column 2. For example, in the example shown in FIG. 1, the insertion portion 31 is arranged only on the upper side of the beam body 30. By arranging the insertion portion 31 in this way, the strength of the wooden beam 3 can be reinforced by arranging the metal rod-shaped member 35 on the side on which the tensile force acts. Further, the rod-shaped member 35 is one side (for example, upper side) of the wooden beam 3 facing upward when attached to the concrete pillar 2, and the other side (for example) of the wooden beam 3 facing downward when attached to the concrete pillar 2. It may be arranged on the lower side) side. In this way, the (tensile) strength in the vertical direction and the horizontal direction (longitudinal direction L) can be improved.
幾つかの実施形態において、木質梁３は、例えば図３（Ａ）及び図５（Ａ）に示すように、長手方向Ｌと交差する方向に延在する貫通孔３２であって、梁本体３０の外部と挿入部３１とを連通する少なくとも一つの貫通孔３２を含んでいてもよい。貫通孔３２は、例えば長手方向Ｌに沿って間隔を隔てて複数個配置されていてもよい。このように、木質梁３が貫通孔３２を含む構成により、挿入部３１に充填剤３８(液体)を注入する際の作業性の向上が図られる。 In some embodiments, the wooden beam 3 is a through hole 32 extending in a direction intersecting the longitudinal direction L, for example, as shown in FIGS. 3 (A) and 5 (A), and is a beam body 30. It may include at least one through hole 32 that communicates with the outside of the insertion portion 31. A plurality of through holes 32 may be arranged at intervals along the longitudinal direction L, for example. As described above, the structure in which the wooden beam 3 includes the through hole 32 improves the workability when the filler 38 (liquid) is injected into the insertion portion 31.
幾つかの実施形態では、例えば図４に示すように、構造体１は、木質梁３又はコンクリート柱２の少なくとも一方に、ボルト孔６２を含むブラケット６０を含んでいてもよい。かかる構成によれば、第１定着部材５１に加えて、ブラケット６０を介してコンクリート柱２と木質梁３との接続強度を向上することができる。 In some embodiments, for example, as shown in FIG. 4, the structure 1 may include brackets 60 including bolt holes 62 in at least one of the wooden beams 3 or the concrete columns 2. According to such a configuration, in addition to the first fixing member 51, the connection strength between the concrete column 2 and the wooden beam 3 can be improved via the bracket 60.
本開示の少なくとも１つの実施形態によれば、強度が補強されるとともに接続が容易な木質梁３、及びこのような木質梁３とコンクリート柱２とを備えた構造体１を提供することできる。 According to at least one embodiment of the present disclosure, it is possible to provide a wooden beam 3 whose strength is reinforced and which is easy to connect, and a structure 1 including such a wooden beam 3 and a concrete column 2.
本発明は上述した実施形態に限定されることはなく、上述した実施形態に変更を加えた形態や、これらの形態を組み合わせた形態も含む。 The present invention is not limited to the above-described embodiment, and includes a modified form of the above-described embodiment and a combination of these embodiments.
