Abstract

L'invention concerne une maison formée par liaison d'aciers de type creux concaves-convexes à haute résistance, qui comprend un coffrage, des parois, un toit, une porte et des fenêtres. Le coffrage comprend des colonnes verticales, des poutres transversales, des sièges de liaison inférieurs, des éléments de liaison angulaires (5) et des structures de liaison de cisaillement creuses concaves-convexes à haute résistance (D2). Les colonnes verticales ou les poutres transversales sont des tuyaux rectangulaires droits creux concaves-convexes à haute résistance (1a) ou des tuyaux rectangulaires arrondis (1b). Chaque élément de liaison angulaire (5) est disposé sur une position d'intersection des tuyaux rectangulaires droits creux concaves-convexes à haute résistance (1a) ou des tuyaux rectangulaires arrondis (1b). Chaque colonne verticale ou chaque poutre transversale comporte également la structure de liaison de cisaillement creuse concave-convexe à haute résistance correspondante (D2), un élément de liaison de sabot externe (D3) et un élément de liaison de sabot interne (D4). Au moyen des éléments de liaison angulaires (5), un liaison rapide et stable est mis en œuvre, la vitesse de construction est élevée, et l'effet est bon. Une encoche (2) pourvu d'une partie renfoncée formée au moyen d'une courbure est formée dans la surface latérale de chaque structure de liaison (D1) de tuyau rectangulaire droit creux concave-convexe à haute résistance ou de tuyau rectangulaire arrondi, une glissière interne (3) formée au moyen d'une courbure est formée dans l'encoche (2), la direction de la glissière interne (3) étant identique à la direction de l'encoche (2), et la largeur de la glissière interne (3) est supérieure à la largeur de l'encoche (2); la conception de structure peut améliorer considérablement le moment d'inertie, en améliorant ainsi la résistance à la torsion et à la courbure du tuyau rectangulaire droit.
