Prefabricated built-in thermal insulation layer foamed concrete composite wall-light steel frame-floor connection node

Abstract

The invention belongs to the technical field of wall joint connection fabrication in building structure engineering, and particularly relates to a prefabricated built-in thermal insulation layer foamed concrete composite wall-light steel frame-floor slab connecting joint. A composite wall is installed in a semi-embedded mode, a built-in thermal insulation layer and inner page foamed concrete are embedded into a light steel frame, and outer page foamed concrete externally covers light steel frame beams and columns. Compared with a traditional prefabricated wall, the wall of the prefabricated built-in thermal insulation layer foamed concrete composite wall-light steel frame-floor slab connecting joint can be used as a structural force-bearing member to transfer loads between the frame beamsand columns, participates in the structural stress of a house and improves the bearing capacity and seismic capacity of the house, and a wall panel is externally wrapped with the steel frame beams andcolumns to effectively reduce the corrosion of steel. According to the composite wall-light steel frame-floor slab joint, bolt holes are prefabricated between components, and bolts are connected intothe bolt holes in a penetrating mode during assembly to realize the connection. The joint is simple in structure form, the connection is reliable, the construction is easy, and the joint can be usedin practical engineering to effectively shorten the construction period and is suitable for widespread popularization and application in low-rise multi-storey light steel frame structures.

Description

Technical field: [0001] The invention belongs to the technical field of wall node connection manufacturing in building structural engineering, and specifically relates to a fabricated built-in thermal insulation layer foamed concrete composite wall-light steel frame-floor connection node and a method of operation. Background technique: [0002] my country is currently in the rapid process of urbanization. By 2020, it will achieve a "comprehensive well-off", the urbanization level will reach about 60%, the urban population will increase by about 300 million, and the number of urbanized housing construction will maintain a relatively high level for a long time. . However, the current new buildings are still constructed in the traditional way of high energy consumption and high pollution. Promoting building industrialization and residential building industrialization is a major measure to realize the transformation of housing construction methods from extensive to intensive, improve...
