Description

本考案は、斜材を用いた建築物の立体トラス構造に関する。   The present invention relates to a three-dimensional truss structure of a building using diagonal materials.

従来の建築構造として、外周に位置する外柱と外梁とを相互に連結するように斜材(ブレース)を設置してトラス構造の構面を形成し、構造物全体の剛性を高める構造が知られている。   As a conventional building structure, there is a structure that increases the rigidity of the whole structure by installing diagonal members (brace) so that the outer pillars and outer beams located on the outer periphery are connected to each other to form the surface of the truss structure. Are known.

特開2007−262753号JP 2007-262755 A

斜材は柱と梁の間に設置されるため、トラス構面上に建築物の出入口や窓等の開口部分を設けようとしても斜材が干渉してしまう。
したがって、外周面の一部分に開口部分を設けるためには、当該箇所をラーメン構造とするなど、斜材を設置しない構造とすることが一般的であった。
Since diagonal materials are installed between columns and beams, diagonal materials interfere even if an opening such as a building entrance / exit or a window is provided on the truss structure.
Therefore, in order to provide an opening in a part of the outer peripheral surface, it has been common to adopt a structure in which the diagonal member is not installed, such as a ramen structure at the location.

前記課題を解決するためになされた本願の第1考案は、高低差を設けて配する複数の外梁と、当該外梁間に立設する柱材及び斜材とからなる、建築物の立体トラス構造であって、前記建築物の隅部のうち少なくとも一箇所において、上方の外梁の隅部から二本の斜材を下方の外梁へ架設して多角形状の解放面を形成し、前記解放面の前面を解放したことを特徴とする、建築物の立体トラス構造を提供するものである。   The first device of the present application, which has been made to solve the above-mentioned problems, is a three-dimensional truss for a building comprising a plurality of outer beams arranged with a height difference, and pillars and diagonal members standing between the outer beams. In the structure, in at least one of the corners of the building, two diagonal members are installed from the corner of the upper outer beam to the lower outer beam to form a polygonal release surface, The present invention provides a three-dimensional truss structure of a building characterized by releasing the front surface of the release surface.

外梁によって囲まれた平面空間の形状はあらゆる多角形状であってもよい。
また、外梁によって囲まれた平面空間面は、トラス構造等を採用して剛構造の床面を形成することもできる。
The shape of the planar space surrounded by the outer beam may be any polygonal shape.
Further, the plane space surface surrounded by the outer beam can adopt a truss structure or the like to form a rigid floor surface.

本願考案によれば、以下に記載する効果のうち、少なくとも何れか一つを得ることができる。
(1)出入口や窓を設ける壁面を有する建築物においても、全周に渡って斜材を用いたトラス構造を形成することができる。したがって、同等の施工コストで構築されるラーメン構造などの従来構造と比較してより安定性の高い構造を提供することができる。
(2)柱、梁材、斜材等の各部材を予め工場で製作しておき、当該部材を現場で組み上げるだけで構造物を構築することができるため、RC造の住宅等と比較して、施工コストの低減及び納期の短縮を図ることができる。
(3)柱、梁材、斜材等の各部材を取り外すだけで容易に建築物の解体を行うことができる。また、取り外し後の各部材を再利用することができるため、施工コストの低減化並びに環境に配慮した形とすることができる。
(4)地震等が発生した場合、水平剪断力の大部分は、建築物の外周面全てに配された斜材に作用し、斜材に発生する軸力で釣り合うように作用するため、ラーメン構造や外周を耐震壁とした構造と比較して、応力が明確化され、解析・構造設計が容易になる。
(5)意匠性に富んだ建築物を構築することができる。
According to the present invention, at least one of the effects described below can be obtained.
(1) A truss structure using diagonal materials can be formed over the entire circumference even in a building having a wall surface on which an entrance and a window are provided. Therefore, it is possible to provide a more stable structure as compared with a conventional structure such as a ramen structure constructed at an equivalent construction cost.
(2) Since each member such as pillars, beams, diagonal members, etc. is manufactured in advance in the factory, and a structure can be constructed simply by assembling the members at the site, compared to RC houses, etc. The construction cost can be reduced and the delivery time can be shortened.
(3) The building can be easily dismantled simply by removing the members such as columns, beams, and diagonal members. Moreover, since each member after removal can be reused, the construction cost can be reduced and the environment can be considered.
(4) When an earthquake or the like occurs, most of the horizontal shearing force acts on the diagonal materials arranged on the entire outer peripheral surface of the building and acts to balance the axial force generated on the diagonal materials. Compared with the structure and the structure where the outer periphery is a seismic wall, the stress is clarified, and analysis and structural design become easy.
(5) A building rich in design can be constructed.
