Masonry structure reinforced by external angle steel frame constructional column and construction method thereof

HUANG TAO / BU FANJUN / DENG XIANGLONG

The invention relates to a masonry structure reinforced by an external angle steel frame constructional column and a construction method thereof. The masonry structure comprises external angle steel, an external angle steel ring beam, tie bolts and an external double-angle steel frame constructional column; the external angle steel is tightly attached to a wall body and a prefabricated floor to be installed along the inner side of a masonry structure outer wall or a masonry structure inner wall, meanwhile, the external angle steel is arranged in parallel corresponding to the outer side of the masonry structure outer wall and tightly attached to the wall body to form a closed whole, and the external angle steel ring beam is formed; the external angle steel and the external angle steel ring beam which are arranged on the two sides of the masonry structure outer wall in parallel are connected through the tie bolts, and the two sides are fixed through nuts; and the external double-angle steel frame constructional column is installed at the joint of the masonry structure outer wall and the masonry structure inner wall and is fixedly connected with the masonry structure outer wall through the tie bolts. The anti-collapse capability and the toughness of the structure can be effectively enhanced.

本发明涉及外加角钢钢架构造柱加固砌体结构及其施工方法，包括外加角钢、外加角钢圈梁、拉结螺栓、外加双角钢钢架构造柱；所述的外加角钢沿砌体结构外墙内侧或砌体结构内墙紧贴墙体和预制楼板进行安装，同时对应砌体结构外墙外侧平行布置外加角钢，并紧贴墙体形成闭合整体，形成外加角钢圈梁；所述的砌体结构外墙两侧平行布置的外加角钢和外加角钢圈梁采用拉结螺栓连接，两侧用螺母进行固定；所述的外加双角钢钢架构造柱安装在砌体结构外墙与砌体结构内墙连接处采用拉结螺栓与砌体结构外墙进行连接固定；本发明能有效地增强结构的抗倒塌能力和结构的韧性。
