Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a telescopic double-plywood connecting device used for connecting a lightweight wall panel with a column. Background Art

[0002] Compared with traditional building forms, prefabricated steel structure buildings mainly have the characteristics of high strength, light weight and high bearing capacity. The strength and rigidity of steel are higher than those of reinforced concrete, so the weight of the steel structure building system is about 1 / 2 of that of the steel-concrete structure, which reduces the weight of the house. The smaller cross-sectional size of steel components can increase the usable space of the building. Because steel is an elastic deformation material, its seismic performance is excellent, which improves the safety and reliability of the building. After the prefabricated steel structure is damaged, it is convenient to replace the damaged components in time; shorten the construction period, reduce labor, improve project quality and construction efficiency, and reduce safety hazards. Most of the prefabricated steel structure components are prefabricated in the factory and then transported to the site for installation; the high degree of on-site mechanization and greatly reduced workload, the corresponding on-site labor force is also greatly reduced, the potential safety accidents are greatly reduced, the construction period is greatly shortened, and the wastewater, noise and dust generated during construction are also greatly reduced.

[0003] The non-load-bearing walls in prefabricated steel structures should be made of lightweight materials to reduce the adverse effects on the seismic resistance of the structure. When masonry walls are used, the wall has a large deadweight and high rigidity, which increases the weight and rigidity of the structure and increases the seismic effect of the structure; the strength of the masonry wall is low and it is easy to be damaged and collapsed in an earthquake. The force-bearing properties of the frame and the masonry wall are different. The lateral stiffness of the frame is small and the deformation capacity is large, while the lateral stiffness of the masonry wall is large and the deformation capacity is small. The deformation of the two is not coordinated during an earthquake, which can easily cause earthquake damage. In recent years, under the guidance of the industry to vigorously develop prefabricated buildings, lightweight strips are being widely used in the partition walls of prefabricated buildings. This type of wall panel has good overall performance and is easy to assemble. The connection between the lightweight partition strips and the frame beams and columns is mostly a combination of cement mortar and U-shaped cards.

[0004] In actual projects, lightweight wall panels and steel frame main structures are mostly connected by U-shaped connectors, and the U-shaped connectors and steel frames are connected by spot welding. This method requires welding operations on site, which is not only complicated in process, but also requires a lot of labor and time. In addition, the heat and deformation problems generated during the welding process will also have a certain impact on the overall quality and stability of the building structure. Therefore, it is necessary to provide a new connection method to solve the problems existing in the traditional connection method and improve the overall assembly rate of prefabricated buildings.
