Description

本発明は、複数の柱から建物外周側に張り出す複数の跳ね出し梁で床スラブが支持されている建物に関する。 The present invention relates to a building in which a floor slab is supported by a plurality of projecting beams protruding from a plurality of columns toward the outer periphery of the building.

例えば、特許文献１の図１１に開示されている建物の架構では、建物における水平方向の直交する二方向に間隔をおいて配置された六本の柱間に亘って、直交する二方向に沿ってトラス格子の梁が架設されている。各柱から建物外周部に向って張り出すトラス格子の跳ね出し梁が設けられている。複数の跳ね出し梁の外端部にわたって、建物外周部に沿う姿勢で跳ね出し梁と同じ梁せいのトラス格子の外梁が設けられている。 For example, in the frame of a building disclosed in FIG. 11 of Patent Document 1, the six columns arranged at intervals in two horizontally orthogonal directions in the building are arranged along two orthogonal directions. The beams of the truss lattice are erected. A truss grid projecting beam is provided from each pillar toward the outer periphery of the building. A truss lattice outer beam having the same beam as the projecting beam is provided over the outer ends of the plurality of projecting beams in a posture along the outer periphery of the building.

特許第２７０８７１０号公報Japanese Patent No. 2708710

上述の建物の架構では、複数の跳ね出し梁の外端部に接続されるトラス外梁が、跳ね出し梁と同じ梁せいに構成されているため、各跳ね出し梁の撓みを抑制する効果が小さい。そのため、跳ね出し梁の撓みを抑制するためには、各跳ね出し梁の部材断面を大きくする必要がある。
この実情に鑑み、本発明の主たる課題は、開放性が高い外観・空間を計画することが可能となる複数の跳ね出し梁を備えた架構を構築する際、複数の跳ね出し梁の撓み及び応力の均等化を図ることのできる建物を提供する点にある。 In the above-mentioned building frame, the truss outer beams connected to the outer ends of the plurality of projecting beams are configured on the same beam as the projecting beams, so that the effect of suppressing the deflection of each projecting beam is effective. small. Therefore, in order to suppress the bending of the protruding beam, it is necessary to increase the member cross section of each protruding beam.
In view of this situation, the main problem of the present invention is the deflection and stress of a plurality of projecting beams when constructing a frame having a plurality of projecting beams that enables planning of an appearance / space with high openness. The point is to provide a building that can equalize the above.

本発明の第１特徴構成は、複数の柱から建物外周側に張り出す複数の跳ね出し梁で床スラブが支持されている建物であって、
複数の前記跳ね出し梁の外端部にわたって、当該跳ね出し梁よりも梁せいの大きな外梁が設けられている点にある。 The first characteristic configuration of the present invention is a building in which the floor slab is supported by a plurality of projecting beams projecting from a plurality of columns to the outer peripheral side of the building.
A point is that an outer beam having a beam diameter larger than that of the protruding beam is provided over the outer ends of the plurality of protruding beams.

本構成によれば、複数の柱から建物外周側に張り出す複数の跳ね出し梁で床スラブが支持されている建物においては、建物外周部が無柱となり、開放性が高い外観・空間を計画することが可能になる。しかも、複数の跳ね出し梁の外端部は、当該跳ね出し梁よりも梁せい（剛性）の大きな外梁で接合されているので、建物外周側に跳ね出し梁による架構を構築した場合においても、複数の跳ね出し梁の撓みを抑制することができる。これにより、複数の跳ね出し梁の撓み及び応力の均等化を図り、跳ね出し梁の部材断面を抑えることができると共に、各跳ね出し梁の部材断面を同程度のサイズとすることができる。 According to this configuration, in a building where the floor slab is supported by multiple protruding beams protruding from multiple pillars to the outer periphery of the building, the outer periphery of the building is pillarless, and the appearance and space with high openness are planned. It becomes possible to do. Moreover, since the outer ends of the plurality of protruding beams are joined by outer beams having a larger beam beam (rigidity) than the protruding beams, even when a frame with the protruding beams is constructed on the outer peripheral side of the building. , It is possible to suppress the bending of a plurality of protruding beams. As a result, the deflection and stress of the plurality of protruding beams can be equalized, the cross section of the members of the protruding beams can be suppressed, and the cross sections of the members of each protruding beam can be made to have the same size.

本発明の第２特徴構成は、前記外梁は、建物外周に沿って環状に構成されている点にある。 The second characteristic configuration of the present invention is that the outer beam is formed in an annular shape along the outer periphery of the building.

本構成によれば、建物外周に沿って環状に構成された梁せいの高い外梁が外周梁として一体に挙動し、複数の跳ね出し梁の撓み、応力の均等化を一層図ることができる。 According to this configuration, the outer beam having a high beam structure formed in an annular shape along the outer periphery of the building behaves integrally as the outer beam, and the deflection and stress equalization of the plurality of protruding beams can be further improved.

本発明の第３特徴構成は、前記外梁は、トラス梁である点にある。 The third characteristic configuration of the present invention is that the outer beam is a truss beam.

本構成によれば、外梁を構成するトラス梁により、重量を軽くしながら、高い剛性で複数の跳ね出し梁の撓み、応力の均等化を一層図ることができる。 According to this configuration, the truss beam constituting the outer beam makes it possible to further equalize the bending and stress of the plurality of protruding beams with high rigidity while reducing the weight.

本発明の第４特徴構成は、前記外梁は、前記跳ね出し梁の上方側及び下方側にそれぞれ延びるように設けられている点にある。 The fourth characteristic configuration of the present invention is that the outer beam is provided so as to extend to the upper side and the lower side of the protruding beam, respectively.

本構成によれば、梁せいの大きな外梁を、建物の外側面に構築される外装パネル等の外壁材で体裁良く覆い隠すことができる。 According to this configuration, the outer beam having a large beam can be covered with an outer wall material such as an exterior panel constructed on the outer surface of the building in a good-looking manner.

本発明の第５特徴構成は、前記外梁は、外壁材用の下地材に構成されている点にある。 The fifth characteristic configuration of the present invention is that the outer beam is formed as a base material for an outer wall material.

本構成によれば、外梁を、建物の外側面に構築される外装パネル等の外壁材用の下地材として兼用することで、躯体数量を低減することができる。 According to this configuration, the number of skeletons can be reduced by also using the outer beam as a base material for an outer wall material such as an exterior panel constructed on the outer surface of a building.
