The concrete portion 190 (see FIGS. 1 and 3) of the present embodiment has the upper and lower joint plate portions 112 and 114 (see FIGS. 1 and 2) around the steel frame portion 110 of the beam-column joint portion 100. It is formed by placing concrete and placing concrete so that the plate surfaces 112A and 114A (see FIGS. 1 and 2) are exposed.

第一木質梁３０の第一梁端部３２から棒状部材の一例としての全ねじボルト５０が突出し、突出した全ねじボルト５０は鉄骨部１１０におけるＨ形鋼で構成された支持部１２０のフランジ部１２２にナット５３を用いて締結されている。また、下側柱２２の柱端部２３及び上側柱２４の柱端部２５からも棒状部材の一例としての全ねじボルト５０が突出し、突出した全ねじボルト５０は鉄骨部１１０における上下の接合板部１１２、１１４にナット５３を用いて締結されている。 A full threaded bolt 50 as an example of a rod-shaped member projects from the first beam end 32 of the first wooden beam 30, and the projecting full threaded bolt 50 is a flange portion of the support section 120 made of H-shaped steel in the steel frame section 110. It is fastened to 122 with a nut 53. A full screw bolt 50 as an example of a rod-shaped member also projects from the post end portion 23 of the lower post 22 and the post end 25 of the upper post 24, and the projecting full screw bolts 50 are the upper and lower joining plates of the steel frame part 110. The nuts 53 are fastened to the portions 112 and 114.
本実施形態では、全ねじボルト５０は、下側柱２２の柱端部２３（図１参照）、上側柱２４の柱端部２５（図１参照）及び第一木質梁３０の第一梁端部３２のそれぞれに形成された挿入穴５２に挿入されている。 In the present embodiment, the full-screw bolt 50 includes the column end portion 23 (see FIG. 1) of the lower column 22, the column end portion 25 (see FIG. 1) of the upper column 24, and the first beam end of the first wooden beam 30.

［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.
柱梁仕口部１００を鉄骨部１１０とコンクリート部１９０とで構成することで、柱梁仕口部１００を高剛性化することができる。また、第一木質梁３０の第一梁端部３２から突出する全ねじボルト５０を柱梁仕口部１００に接合することで、第一木質梁３０を柱梁仕口部１００に容易に接合することができる。 By constructing the column-beam joint portion 100 with the steel frame portion 110 and the concrete portion 190, the column-beam joint portion 100 can be made highly rigid. In addition, the first wooden beam 30 is easily joined to the beam/column joint 100 by joining the all-screw bolts 50 protruding from the first beam end 32 of the first wooden beam 30 to the beam/column joint 100. can do.
また、第一梁端部３２から突出する全ねじボルト５０は、柱梁仕口部１００を構成する鉄骨部１１０のＨ形鋼で構成された支持部１２０のフランジ部１２２に締結されているので、全ねじボルト５０に作用する引張力を柱梁仕口部１００に効果的に伝達することができる。 Further, the full screw bolt 50 protruding from the first beam end portion 32 is fastened to the flange portion 122 of the support portion 120 made of the H-shaped steel of the steel frame portion 110 constituting the column beam joint portion 100. The tensile force that acts on the full-threaded bolt 50 can be effectively transmitted to the column-beam joint portion 100.
なお、第一梁端部３２から突出する全ねじボルト５０を、柱梁仕口部１００を構成するコンクリート部１９０に埋設させて接合してもよい。この場合、第一梁端部３２のレベル調整等の位置調整が容易である。 The full-screw bolts 50 projecting from the first beam end 32 may be embedded and joined in the concrete portion 190 that constitutes the post-beam joint portion 100. In this case, position adjustment such as level adjustment of the first beam end 32 is easy.
また、柱梁仕口部１００のコンクリート部１９０に設けられ凸部１９２が第一梁端部３２に設けられた凹部３４に係合することで、第一梁端部３２と柱梁仕口部１００との間でせん断力が効果的に伝達される。よって、凸部１９２及び凹部３４が無く、全ねじボルト５０でせん断力を伝達する比較例の場合よりも、大きなせん断力を効果的に伝達することができる。 Further, the convex portion 192 provided on the concrete portion 190 of the pillar-beam joint portion 100 is engaged with the concave portion 34 formed on the first beam end portion 32, so that the first beam end portion 32 and the pillar-beam joint portion are formed. Shear force is effectively transmitted to and from 100. Therefore, it is possible to effectively transmit a large shearing force as compared with the case of the comparative example in which the projection 192 and the recess 34 are not provided and the shearing force is transmitted by the full screw bolt 50.
また、鉄骨部１１０とコンクリート部１９０とで構成された柱梁仕口部１００の上下に接合する上側柱２４及び下側柱２２を、鉄骨部１１０の接合板部１１２、１１４に接合することで、上側柱２４と下側柱２２との間の軸力伝達力及び曲げ応力伝達力の両方が向上する。 In addition, by joining the upper and lower columns 24 and 22 that are joined to the top and bottom of the beam-column joint unit 100 composed of the steel frame portion 110 and the concrete portion 190 to the joint plate portions 112 and 114 of the steel frame portion 110, Both the axial force transmitting force and the bending stress transmitting force between the upper column 24 and the lower column 22 are improved.
また、本実施形態では、全ねじボルト５０が挿入されている挿入穴５２には、拡径部５４が形成されている。よって、拡径部５４に充填された充填材Ｇは、挿入穴５２から全ねじボルト５０が引き抜かれる引抜き力に抵抗する引抜き抵抗部として機能する。これにより、下側柱２２の柱端部２３、上側柱２４の柱端部２５及び第一木質梁３０の第一梁端部３２と、全ねじボルト５０との接合強度が高められる。そして、この結果、下側柱２２の柱端部２３、上側柱２４の柱端部２５及び第一木質梁３０の第一梁端部３２と、柱梁仕口部１００との接合強度が高められる。 Further, in the present embodiment, the expanded diameter portion 54 is formed in the insertion hole 52 into which the full screw bolt 50 is inserted. Therefore, the filler G filled in the expanded diameter portion 54 functions as a pull-out resistance portion that resists the pull-out force with which the full-screw bolt 50 is pulled out from the insertion hole 52. As a result, the joint strength between the column end 23 of the lower column 22, the column end 25 of the upper column 24, the first beam end 32 of the first wooden beam 30, and the full-screw bolt 50 is increased. Then, as a result, the joint strength between the pillar end portion 23 of the lower pillar 22, the pillar end portion 25 of the upper pillar 24, the first beam end portion 32 of the first wooden beam 30, and the pillar beam joint portion 100 is increased.
