Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building construction technology, and in particular relates to a prefabricated cold-formed thin-walled steel composite wall with a structural frame. Background Technology

[0002] Cold-formed steel structures have advantages such as light weight, high degree of prefabrication and assembly, and convenient construction. They are widely used abroad. Developing cold-formed steel structure systems in my country not only meets the national requirements for green building and sustainable development strategy, but also plays an important role in promoting the industrialization of housing and enhancing the innovation capabilities of my country's steel structure energy-saving housing technology. In recent years, with the support and promotion of a series of policies in my country, prefabricated low-rise cold-formed steel structure houses have been widely used.

[0003] As the main load-bearing component, the composite wall of the cold-formed steel structure system not only bears the vertical load transmitted by the roof and floor, but also resists the horizontal seismic action and wind load. However, a "cavity effect" will occur between the wall panels on both sides of the cold-formed steel composite wall, which weakens its shear bearing capacity and lateral stiffness, and results in poor thermal insulation performance and poor living experience. This affects the seismic performance and comfort of cold-formed steel structure houses, which contradicts the long-standing architectural concept of "Qin bricks and Han tiles" in my country. Moreover, due to my country's large population and limited land, multi-story cold-formed steel structure housing is more in line with my country's national conditions. Therefore, the development of cold-formed steel structure houses from low-rise to multi-story is an inevitable trend. In order to solve the above problems, there is an urgent need for a prefabricated cold-formed thin-walled steel composite wall with a structural frame. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the "cavity effect" between the two wall panels of cold-formed steel composite walls results in weak shear bearing capacity, lateral stiffness, and poor thermal insulation performance. At the same time, based on the concept of the "ring beam-structural column" (structural frame) seismic system in masonry structures, a prefabricated cold-formed thin-walled steel composite wall with a structural frame is proposed, thereby expanding the new ideas for the development of cold-formed steel residential buildings from low-rise to multi-story.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a prefabricated cold-formed thin-walled steel composite wall with a structural frame, comprising a left frame column and a right frame column. The top of the left and right frame columns are provided with upper frame beams, and the bottom of the left and right frame columns are provided with lower frame beams. Side columns are provided on one side of each of the left and right frame columns. An upper guide rail is provided on the bottom surface of the upper frame beam, and a lower guide rail is provided on the top surface of the lower frame beam. A central column is provided between the upper and lower guide rails. Steel plates are fixedly installed at both ends of the upper and lower frame beams. Wall panels are provided on both sides of the central column, and filler material is provided between the wall panels. Self-tapping screws are provided on the surface of the wall panels. Multiple connection holes are provided inside the left frame column, right frame column, side column, central column, steel plate, upper guide rail, and lower guide rail.

[0006] As a further description of the above technical solution:

[0007] The steel plate is connected to the left and right frame columns via bolts through connecting holes. The left and right frame columns are also connected to the side columns via bolts through connecting holes. The left and right frame columns are made of square steel pipes.

[0008] As a further description of the above technical solution:

[0009] The upper frame beam and the upper guide rail are connected by bolts through connecting holes, and the lower frame beam and the lower guide rail are connected by bolts through connecting holes. The upper frame beam and the lower frame beam are made of hot-rolled H-beams, and the upper guide rail and the lower guide rail are made of cold-formed U-beams.

[0010] As a further description of the above technical solution:

[0011] The wall panels are connected to the side columns and the central columns by self-tapping screws. Multiple central columns are provided and evenly distributed among the wall panels. The side columns and the central columns are made of cold-formed C-shaped steel. The wall panels are made of gypsum board and the filler is vitrified microsphere thermal insulation concrete.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by connecting the upper and lower frame beams to the left and right side frame columns at both ends, and connecting the side columns and multiple middle columns to the upper and lower guide rails, the wall panels are connected to the columns using self-tapping screws. Filling the cavities between the wall panels with filler not only solves the cavity effect but also increases the wall's load-bearing capacity, forming a structure with dual lateral resistance, thus improving overall lateral resistance. The filler uses vitrified microsphere insulating concrete, which provides earthquake resistance, economy, energy saving, and insulation, increasing living comfort. "Ring beams" are set on the upper and lower sides of the wall, and "structural columns" are set on the left and right sides, thus forming a "structural frame cold-formed steel composite shear wall," which has excellent earthquake resistance and expands the new development path of cold-formed steel from low-rise to multi-story buildings.
