[0017] Example 1

[0018] As Figures 1-3The illustrated slat-cold-formed thin-walled structure includes: structural nodes 1, slats 2, and load-bearing components 3. The structural nodes 1 are cylindrical welded nodes. The slats 2 are disposed on the sides of the structural nodes 1, with corresponding conical curves cut at their connecting ends to ensure a close fit between the connecting ends and the connecting surfaces of the structural nodes 1. The slats 2 and structural nodes 1 are welded together. The load-bearing components 3 are C-shaped light steel keels, with several evenly distributed among the slats 2, and adjacent load-bearing components 3 on the same plane have corresponding connection positions on both sides of the slats 2. When dealing with complex three-dimensional spatial structures and component manufacturing, a dimensional reduction method is used, employing strip-shaped slats 2 and load-bearing components 3 as tie rods and main load-bearing structures respectively, facilitating processing. Furthermore, the cylindrical welded nodes of the structural nodes 1 are unaffected by the building's geometry, and the slats can be connected at any angle outside the cylindrical welded nodes, resulting in strong structural integrity.

[0019] In this embodiment, the structural node 1 and the slat 2 are made of non-galvanized carbon steel, and are coated with anti-rust paint after welding. This effectively prevents the steel from corroding and rusting, thereby extending the service life of the steel.

[0020] Example 2

[0021] Based on Example 1, in this example, as... Figure 2 The illustrated slat-cold-formed thin-walled structure ensures that the load-bearing members 3 on both sides of the slat 2 have the same dimensions as the connecting end face of the slat 2, which can improve the more reliable load transfer.

[0022] In this embodiment, the load-bearing component 3 and the slat 2 are connected by welding or by using self-tapping screws and L-shaped connectors, which can facilitate on-site construction, shorten the construction period, and ensure structural strength.

[0023] like Figure 1 , 3 The illustrated slat-cold-formed thin-walled structure has load-bearing members 3 connected so that the planar layers are parallel to each other. The upper and lower flange planes of the load-bearing members 3 are parallel to the surface of the building geometry, which facilitates the laying of base panels and other building cladding panels. Moreover, this design structure has significant advantages for the construction of irregular polyhedral building structures. When connecting two member planes with large corners, the structural node 1 where the two planes intersect can be welded first to form a common node. From this node, the connecting slats 2 can be extended outwards before the load-bearing members 3 are laid.

[0024] In this embodiment, the width of the load-bearing component 3 is greater than or equal to the width of the strip 2. When installing the outer panel of the building, the panel can cover the inside from the outside, which facilitates waterproofing at the connection point on the outside.

[0025] It should be noted that the above only describes the technical solutions of the utility model and is not limited. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the utility model technical solutions can be modified or replaced equivalently without departing from the scope of the utility model technical solutions, and all should be covered in the scope of the claims of the utility model.
