Connecting joint of fabricated concrete composite wall with built-in thermal insulation layer and light steel frame

Abstract

The invention belongs to the technical field of connecting and manufacturing of wall joints in building structure engineering and particularly relates to a connecting joint of a fabricated concrete composite wall with a built-in thermal insulation layer and a light steel frame. The composite wall is mounted in a semi-embedded mode, and the built-in thermal insulation layer and inner sheet concreteare embedded into the light steel frame. Beam columns of the light steel frame are externally wrapped with outer sheet concrete. Compared with a traditional fabricated wall, the wall can serve as a structural force-bearing component, transmits loads with the frame beam columns, and participates in house structural force bearing, the house bearing capacity and anti-seismic capacity are improved, wallboards are wrapped with the frame beam columns, and thus steel corrosion is effectively reduced. The joint of the composite wall and the frame achieves bolted connection by means of the methods that bolts are pre-buried into the composite wall and connecting angle steel is welded to the frame structure beam columns, the structure form of the joint is simple, connecting is reliable, constructionis easy, the joint is applied to practical engineering, the building period can be effectively shortened, and the joint is suitable for being applied and popularized in low-rise and high-rise light steel frame structures.

Description

Technical field: [0001] The invention belongs to the technical field of wall connection node production in building structure engineering, and in particular relates to an assembled concrete composite wall-light steel frame connection node with a built-in thermal insulation layer and a method thereof. 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 housi...
