Description

Technical Field

[0001] The present application relates to the technical field of wall node installation in building construction, and in particular to a light steel keel lightweight composite wall node installation structure. Background Art

[0002] At present, light steel structure buildings have been widely used at home and abroad due to their light weight, fast construction speed, and good seismic performance. However, the traditional lightweight composite wall node installation technology has problems such as complex installation, low construction efficiency, and poor stability. In recent years, with the continuous advancement of building materials and technologies, the node installation technology of lightweight composite walls has gradually developed towards simplification and standardization, but there are still many technical bottlenecks.

[0003] Existing technical solutions include the traditional bolt connection method, which uses pre-buried steel plates and bolts to fix the light steel keel to the concrete foundation, and then embeds the lightweight composite wall panels between the light steel keels. This method has the advantages of simple structure and low cost, but the disadvantages are that the installation process is cumbersome and time-consuming, and the bolts are prone to loosening, resulting in poor wall stability. The welding connection method, which fixes the light steel keel to the foundation by welding, and then adheres the lightweight composite wall panels to the light steel keel. This method has the advantage of high connection strength, but the disadvantages are that the construction is difficult, the welding quality is difficult to ensure, and the welding points are prone to stress concentration, affecting the safety and durability of the overall structure. The fastener connection method, which uses special fasteners to fix the light steel keel to the foundation, and then clips the lightweight composite wall panels into the slots of the light steel keel. This method has the advantage of easy and quick installation, but the disadvantage is that the fasteners are prone to aging, and the reliability decreases after long-term use.

[0004] Therefore, although the common bolt connection method, welding connection method and fastener connection method in the existing technology each have their own advantages, they also have obvious shortcomings. The bolt connection method is complicated and time-consuming to install, the welding connection method is difficult to construct and the welding quality is difficult to ensure, and the reliability of the fastener connection method decreases after long-term use. These defects limit the promotion and application of lightweight composite walls in actual projects.
