To provide a gate-type structure capable of reducing a deflection amount at the center of a beam and reducing weight of the whole beam by devising a structure of a beam itself and specifying a support structure of a beam so as to have a desired sectional performance equal to or more than a predetermined value corresponding to a bending moment or a generated stress of the beam.SOLUTION: In a gate-type structure 100 having struts 2 on both sides and a beam 1 extending in the horizontal direction between the struts 2, the beam 1 is formed as a tapered pipe 3 in which at least a part in the extending direction is thicker toward the beam central portion and thinner toward the beam end, and both end parts are connected to each other by a simple support which can be rotated with respect to the strut 100.SELECTED DRAWING: Figure 1
【課題】梁自体の構造に工夫を加えるとともに梁の支持構造を特定することにより、梁の発生曲げモーメントや発生応力に見合った所定以上の望ましい断面性能を持たせ、それによって梁中央の撓み量の低減や梁全体の軽量化が可能な門型構造体を提供する。【解決手段】両側の支柱２と、支柱２間にわたって水平方向に延びる梁１とを有する門型構造体１００において、梁１は、その延在方向における少なくとも一部が、梁中央部側ほど太く梁端部側ほど細くなるテーパー管３に構成されているとともに、その両端部が、支柱に対し、回動自在の単純支持にて連結されていることを特徴とする門型構造体１００。【選択図】図１
