Description

本発明は、鋼製の柱部材に鋼製の梁部材を接合する柱梁接合構造に関する。 The present invention relates to a column-beam joining structure for joining a steel beam member to a steel column member.

この柱梁接合構造のように、一般に、梁部材は、梁部材の材軸の延長線と柱部材の材軸とが交わるようにして柱部材に接合されているので、柱部材の配置によって梁部材の配置が決まってしまう。 Like this beam-column joint structure, the beam member is generally joined to the column member so that the extension line of the material axis of the beam member intersects with the material axis of the column member. The arrangement of the members is decided.

よって、建物において、決められた鋼製の柱部材の配置に基づいて配置された鋼製の梁部材を避けて有効な室内空間が形成される場合、有効な室内空間が狭くなってしまうことが問題となる。 Therefore, in a building, when an effective interior space is formed by avoiding the steel beam members arranged based on the predetermined arrangement of the steel column members, the effective interior space may be narrowed. It becomes a problem.

次に、本発明の実施形態に係る柱梁接合構造の作用と効果について説明する。 Next, the operation and effect of the column-beam joint structure according to the embodiment of the present invention will be described.

本実施形態の柱梁接合構造２４では、図２、図３及び図５に示すように、柱部材１４Ａから張り出して設けられた接合部材２６に梁部材としての小梁１８を接合することにより、柱部材１４Ａに対して偏心した位置に（柱部材１４Ａの材軸から横方向へずれた位置に小梁１８の材軸の延長線がくるように）小梁１８を配置することができ、これによって有効な室内空間を広くすることができる。 In the column-beam joining structure 24 of the present embodiment, as shown in FIGS. 2, 3 and 5, the beam 18 as a beam member is joined to the joining member 26 overhanging from the column member 14A. The beam 18 can be arranged at a position eccentric with respect to the column member 14A (so that the extension line of the material axis of the beam 18 comes at a position laterally displaced from the material axis of the column member 14A). The effective indoor space can be widened.

従来の建物において、決められた柱部材の配置に基づいて配置された梁部材を避けて有効な室内空間が形成される場合、浴室等の床下がりや設備シャフトなどによって、有効な室内空間が狭くなってしまうことがある。 In a conventional building, when an effective interior space is formed by avoiding the beam members arranged based on the predetermined arrangement of the pillar members, the effective interior space is narrowed due to the floor lowering of the bathroom or the equipment shaft. It may become.

例えば、図６の側面断面図に示す柱梁接合構造７６のように、角形鋼管からなる柱部材７８の材軸と、Ｈ形鋼からなる梁部材８０の材軸の延長線とが交わるようにして、梁部材８０が柱部材７８に接合され、この梁部材８０に床下がりを有する床スラブ８２の上段部分が支持されている場合、柱部材７８の右側面８４付近から右側が有効な室内空間Ｓとなるので、有効な室内空間Ｓが狭くなってしまう。図６では、設備配管８６が、床スラブ８２の下方に床スラブ８２に沿って配置され、梁部材８０を貫通している。 For example, as in the beam-column joint structure 76 shown in the side sectional view of FIG. 6, the material shaft of the column member 78 made of square steel pipe and the extension line of the material shaft of the beam member 80 made of H-shaped steel intersect. When the beam member 80 is joined to the pillar member 78 and the upper portion of the floor slab 82 having a floor drop is supported by the beam member 80, the right side from the vicinity of the right side surface 84 of the pillar member 78 is an effective indoor space. Since it becomes S, the effective indoor space S becomes narrow. In FIG. 6, the equipment pipe 86 is arranged below the floor slab 82 along the floor slab 82 and penetrates the beam member 80.

また、例えば、図７の側面断面図に示す柱梁接合構造８８のように、角形鋼管からなる柱部材７８の材軸と、Ｈ形鋼からなる梁部材８０の材軸の延長線とが交わるようにして、梁部材８０が柱部材７８に接合され、この梁部材８０に床下がりを有する床スラブ８２の上段部分が支持されており、さらに、設備シャフトＰが配置されている場合、設備シャフトＰは、梁部材８０を避けて（梁部材８０の隣りに）配置され、この配置された設備シャフトＰの右側面９０付近から右側が有効な室内空間Ｓとなるので、有効な室内空間Ｓが狭くなってしまう。図７では、設備配管８６が、床スラブ８２の下方に床スラブ８２に沿って配置され、梁部材８０を貫通している。 Further, for example, as in the beam-column joint structure 88 shown in the side sectional view of FIG. 7, the material shaft of the column member 78 made of square steel pipe and the extension line of the material shaft of the beam member 80 made of H-shaped steel intersect. In this way, when the beam member 80 is joined to the pillar member 78, the upper portion of the floor slab 82 having a floor drop is supported by the beam member 80, and the equipment shaft P is arranged, the equipment shaft is further arranged. P is arranged avoiding the beam member 80 (next to the beam member 80), and the right side from the vicinity of the right side surface 90 of the arranged equipment shaft P is the effective indoor space S, so that the effective indoor space S is It gets narrower. In FIG. 7, the equipment pipe 86 is arranged below the floor slab 82 along the floor slab 82 and penetrates the beam member 80.

さらに、例えば、図８の側断面図に示す柱梁接合構造９２のように、角形鋼管からなる柱部材７８の材軸と、Ｈ形鋼からなる梁部材８０の材軸の延長線とが交わるようにして、梁部材８０が柱部材７８に接合され、この梁部材８０に床下がりを有する床スラブ８２の下段部分が支持されている場合、梁部材８０の下方に十分な高さが確保できず、柱部材７８の右側面８４付近から右側が有効な室内空間Ｓとなるので、有効な室内空間Ｓが狭くなってしまう。また、梁部材８０の位置を高くして梁部材８０の下方に十分な高さを確保しようとすると、階高が高くなってしまう。図８では、設備配管８６が、床スラブ８２の下方に床スラブ８２に沿って配置され、梁部材８０を貫通している。 Further, for example, as in the beam-column joint structure 92 shown in the side sectional view of FIG. 8, the material shaft of the column member 78 made of square steel pipe and the extension line of the material shaft of the beam member 80 made of H-shaped steel intersect. In this way, when the beam member 80 is joined to the column member 78 and the lower portion of the floor slab 82 having a floor drop is supported by the beam member 80, a sufficient height can be secured below the beam member 80. However, since the right side from the vicinity of the right side surface 84 of the pillar member 78 becomes the effective indoor space S, the effective indoor space S becomes narrow. Further, if the position of the beam member 80 is raised to secure a sufficient height below the beam member 80, the floor height becomes high. In FIG. 8, the equipment pipe 86 is arranged below the floor slab 82 along the floor slab 82 and penetrates the beam member 80.

これに対して、本実施形態の柱梁接合構造２４では、図９の側面断面図に示すように、柱部材１４Ａに対して偏心した位置に梁部材としての小梁１８を配置することができるので、小梁１８を柱部材１４Ａの左側へ配置することにより、床スラブ８２の床下がりの段差を柱部材１４Ａの左側面９４付近に配置することができる。これにより、柱部材１４Ａの左側面９４付近から右側が有効な室内空間Ｓとなる。また、床下がりを有する床スラブ８２の上段部分を梁部材１８に支持させることにより、階高を高くせずに梁部材１８の下方に十分な高さを確保することができる。 On the other hand, in the column-beam joint structure 24 of the present embodiment, as shown in the side sectional view of FIG. 9, the beam 18 as a beam member can be arranged at a position eccentric with respect to the column member 14A. Therefore, by arranging the beam 18 on the left side of the column member 14A, the step of the floor slab 82 can be arranged near the left side surface 94 of the column member 14A. As a result, the space S from the vicinity of the left side surface 94 of the pillar member 14A to the right side becomes an effective interior space S. Further, by supporting the upper portion of the floor slab 82 having the floor lowering by the beam member 18, it is possible to secure a sufficient height below the beam member 18 without increasing the floor height.

すなわち、図６～８に示す、柱部材７８の材軸と梁部材８０の材軸の延長線とが交わるようにして梁部材８０が柱部材７８に接合されている柱梁接合構造７６、８８、９２と比べて、図９に示す柱梁接合構造２４は、有効な室内空間Ｓを広くすることができる。 That is, the column-beam joining structures 76 and 88 in which the beam member 80 is joined to the column member 78 so that the material axis of the column member 78 and the extension line of the material axis of the beam member 80 intersect as shown in FIGS. , 92, the column-beam joint structure 24 shown in FIG. 9 can widen the effective indoor space S.

また、本実施形態の柱梁接合構造２４では、図４に示すように、小梁１８を接合部材２６に剛接合することにより、図１に示すように、柱部材１４Ａと小梁１８とを有して構成される柱梁架構５２を、地震時の水平せん断力の負担が可能な構造フレームとすることができる。 Further, in the column-beam joining structure 24 of the present embodiment, as shown in FIG. 4, the beam 18 is rigidly joined to the joining member 26, so that the column member 14A and the beam 18 are joined to each other as shown in FIG. The column-beam frame 52 can be used as a structural frame capable of bearing the horizontal shear force at the time of an earthquake.

さらに、本実施形態の柱梁接合構造２４では、図２～５に示すように、接合部材２６を、下ダイアフラムとしての通しダイアフラム２８と、上ダイアフラムとしての通しダイアフラム３０と、リブ３２、３４、３６、３８と、を有して構成することにより、小梁１８に作用する曲げモーメントを接合部材２６のねじれモーメントとして柱部材１４Ａへ伝達することができる。 Further, in the beam-column joining structure 24 of the present embodiment, as shown in FIGS. 2 to 5, the joining member 26 has a through diaphragm 28 as a lower diaphragm, a through diaphragm 30 as an upper diaphragm, and ribs 32 and 34. By having 36 and 38, the bending moment acting on the beam 18 can be transmitted to the column member 14A as the twisting moment of the joining member 26.

以上、本発明の実施形態について説明した。 The embodiment of the present invention has been described above.
