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

Abstract

The invention belongs to the technical field of wall joint connecting and manufacturing in building structure engineering, and particularly relates to a prefabricated built-in insulating layer foamedconcrete composite wall-light steel frame connection joint. A composite wall is installed in a half-embedded mode, a built-in insulating layer and inner sheet foamed concrete are embedded into a lightsteel frame, and external sheet foamed concrete externally covers a light steel frame beam-column. Compared with a traditional prefabricated wall, a wall body of the prefabricated built-in insulatinglayer foamed concrete composite wall-light steel frame connection joint can be used as a structural stress member, mutually transfers the load with the frame beam-column, participates in the structure stress of a building, and improves bearing capacity and anti-seismic capacity of the building, and a wallboard externally covers the steel frame beam-column to effectively reduce the corrosion of steel. The composite wall-frame joint realizes the bolt connection by pre-embedding bolts in the composite wall and welding connection angle iron on the frame structure beam-column; and the prefabricated built-in insulating layer foamed concrete composite wall-light steel frame connection joint is simple in structure form, reliable in connection and easy to construct, can effectively shorten the construction period when applied to practical engineering, and is suitable for wide popularization and application in low multi-layer light steel frame structures.

Description

Technical field: [0001] The invention belongs to the technical field of making wall connection 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 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, improve housing qual...
