Description

Technical Field

[0001] This utility model relates to the field of light steel building technology, specifically to light steel roofing. Background Technology

[0002] Light steel frame construction is an innovative building form that primarily uses lightweight steel structures. It mainly employs cold-formed thin-walled steel or lightweight hot-rolled steel as the load-bearing frame, and is assembled on-site using prefabricated components in a factory. It is suitable for low-rise residential buildings, office buildings, warehouses, and other similar applications. A light steel frame roof is the roofing system within a light steel structure, specifically designed for light steel buildings. It typically consists of frame components, side cover components, and a top panel component, achieving sealing and stability through assembly.

[0003] For example, patent application CN201710390119.8, published on October 27, 2017, describes a lightweight steel integrated prefabricated roof, comprising a lightweight steel integrated roof frame and roof panels. The lightweight steel integrated roof frame includes a roof truss bottom beam, roof truss columns, and roof beams. The roof panels include OSB panels, lightweight energy-saving composite panels, a waterproof layer, and lightweight roofing tiles. The roof panels are installed on the lightweight steel integrated roof frame via connecting components. This invention offers advantages such as lightweight, high strength, multiple environmental benefits, sound insulation, waterproofing, rapid construction, and cost reduction. The roof panels are produced through a streamlined process of casting, leveling, and curing, resulting in a high degree of automation and a wide variety of specifications.

[0004] Traditional light steel roofs rely on external waterproofing layers at the joints, which are prone to leakage due to deformation over long-term use. Furthermore, their thermal insulation and sound insulation properties largely depend on later filling, increasing construction complexity. Therefore, there is an urgent need to design light steel roofs to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a lightweight steel roof to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A light steel roof includes a frame assembly, side cover assemblies, and a top plate assembly. Two side cover assemblies are installed at both ends of the frame assembly, and two top plate assemblies are installed on top of the frame assembly and assembled together. The top plate assembly includes a frame, a first cover plate, multiple filler plates, and a second cover plate. The outer walls of both sides of the frame are provided with mounting grooves, and multiple mounting openings are provided between two mounting grooves. The filler plates fill the corresponding mounting openings. The first cover plate is installed in one of the mounting grooves by bolts. One side of the outer wall of the second cover plate has an integrally formed protrusion, which is installed in another mounting groove by bolts. One side of the outer wall of the frame has an opening groove. After the two frames are assembled, the opening grooves of the two frames form a space, which is filled with a sealing strip to achieve a seal. One side of the outer wall of the frame has an integrally formed insertion block, and one side of the outer wall of the insertion block has multiple through holes.

[0008] Furthermore, the frame assembly includes a crossbeam, and the top two outer walls of the crossbeam are provided with insertion grooves, the insertion block is inserted into the insertion groove, and slots are provided at both ends of the crossbeam.

[0009] Furthermore, a number of insertion holes are provided on one side of the outer wall of the crossbeam. The insertion holes penetrate two insertion slots, and the insertion holes correspond one-to-one with the through holes.

[0010] Furthermore, the skeleton assembly also includes several support frames, with multiple triangular frames integrally formed on one side of the top outer wall of each support frame, and through holes provided on one side of the outer wall of each support frame.

[0011] Furthermore, the frame assembly also includes fixing bolts that are inserted into and pass through the insertion holes to fix the insertion block, and fixing bolts that pass through the through holes to fix the support frame.

[0012] Furthermore, the side cover assembly includes a side cover plate, and a plurality of triangular blocks are welded to one outer wall of the side cover plate, the triangular blocks being inserted into the inside of the tripod.

[0013] Furthermore, a rectangular insert is welded to one outer wall of the side cover plate, and the rectangular insert is inserted into the slot.

[0014] In the above technical solution, the lightweight steel roof provided by this utility model has the following beneficial effects:

[0015] This utility model's roof panel assembly is assembled by filling sealing strips through the opening slots of the frame to form a built-in sealing structure, avoiding the problem of easy aging and leakage of traditional external waterproof layers, and significantly improving the overall sealing and waterproof performance of the roof. At the same time, the modular design of the filling plate and the installation port realizes the integrated integration of heat preservation and sound insulation functions, reducing secondary construction procedures on site.

[0016] This utility model's crossbeam and plug-in block, through the precise positioning design of the plug-in groove and through hole, combined with the fixing bolts, achieve rapid alignment and locking between components, significantly improving assembly efficiency and conforming to the industrial construction characteristics of cold-formed thin-walled steel systems.

[0017] The support frame and the triangular frame of this utility model form a truss-type force-bearing system. Through the composite connection of through holes and fixing bolts, the overall resistance to lateral deformation of the roof is enhanced, which meets the requirements of high-strength seismic fortification.

[0018] This utility model's side cover plate, through the interlocking design of triangular blocks and rectangular inserts with the frame components, supports the flexible replacement of enclosure panels of different specifications, adapting to diverse architectural design needs.
