Prefabricated built-in thermal insulation layer foamed concrete composite wall-light steel frame-floor slab connecting joint

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 connection and production of wall nodes in building structure engineering, and in particular relates to an assembly-type built-in thermal insulation layer foam concrete composite wall-light steel frame-floor connection node and its method. Background technique: [0002] At present, my country is in the rapid process of urbanization. By 2020, it will achieve "all-round 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 remain at a relatively high level for a long time . However, the current newly-added buildings are still built in the traditional rough building method with high energy consumption and high pollution. Promoting the industrialization of construction and housing construction is a major measure to realize the transformation of housing construction from extensive to intensive, imp...
