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.
