Description

Technical Field

[0001] This utility model relates to a high-strength steel structure U-shaped plate, belonging to the field of building engineering technology. Background Technology

[0002] In construction engineering, U-shaped panels are common prefabricated or on-site installed components, mainly used in building envelopes, roofs, walls, or floor systems. Existing U-shaped panels are usually made of metal (such as galvanized steel plates or aluminum plates) or concrete into rectangular containers with the opening facing upwards. The interior is filled with materials such as concrete and insulation layers to provide high lateral stiffness and load-bearing capacity. The sides of existing U-shaped panels are all straight, resulting in low support strength. When the length of the U-shaped panel is long, deformation is likely to occur. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a high-strength steel structure U-shaped plate, in which the reinforcing member provides better connection and support strength for the U-shaped plate, which can overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a high-strength steel structure U-shaped plate, including a channel-shaped component and sealing plates fixed at both ends of the channel-shaped component. The channel-shaped component includes a horizontal plate and two side plates located on both sides of the horizontal plate, and includes a number of transversely distributed reinforcing members. The side plates are stepped and form a limiting groove with the horizontal plate. The cross section of the channel-shaped component is a convex shape with an open top. The reinforcing members are welded and fixed to the channel-shaped component, and the two ends of the reinforcing members are located in the limiting groove.

[0005] Further, it includes several longitudinally distributed reinforcing members II, which are fixed on the reinforcing members and connected to the sealing plate at both ends.

[0006] Furthermore, the top of the sealing plate and side plate has a flanged structure.

[0007] Furthermore, the reinforcing member and the second reinforcing member are rectangular steel pipes.

[0008] Furthermore, the grooved component and the sealing plate surface are provided with an anti-corrosion layer.

[0009] By implementing this utility model, the side plate of the grooved component is stepped, which significantly improves the torsional resistance. Several reinforcing members are horizontally placed inside the grooved component, with both ends of the reinforcing members located in the limiting groove. The reinforcing members provide lateral support to the grooved component and provide support and connection to the bending point of the side plate, further enhancing the connection strength and improving the torsional resistance.

[0013] Embodiments of this utility model: such as Figures 1 to 2 As shown, a high-strength steel U-shaped plate includes a channel-shaped component 1 and sealing plates 2 fixed at both ends of the channel-shaped component 1. The channel-shaped component 1 and the sealing plates 2 are made of steel plates. The channel-shaped component 1 is formed by bending the steel plate into a convex shape with an open top by a bending machine. It includes a horizontal plate 3 and side plates 4 located on both sides of the horizontal plate 3. The side plates 4 are stepped and form a limiting groove 5 between them and the horizontal plate 3. Several horizontally distributed reinforcing members 6 are provided in the channel-shaped component 1. The sealing plates 2 are welded to both ends of the channel-shaped component 1 to form a container with an open top. The reinforcing members 6 are welded and fixed to the channel-shaped component, and their two ends are respectively located in the limiting groove 5 to support and connect the folded edges of the side plates 4. The stepped side plates 4 significantly improve the torsional resistance. Several reinforcing members 6 are horizontally placed in the channel-shaped component 1, and the two ends of the reinforcing members 6 are located in the limiting groove 5 to provide lateral support to the channel-shaped component 1 and to support and connect the folded edges of the side plates 4, further enhancing the connection strength and improving the torsional resistance.

[0014] As a preferred embodiment, it includes several longitudinally distributed reinforcing members 7, which are fixed on the reinforcing member 6 and connected to the sealing plate 2 at both ends. The reinforcing members 7 provide longitudinal support and further increase the overall strength.

[0015] As a preferred embodiment, the top of the sealing plate 2 and the side plate 4 have a flange structure 8, forming a double-layer structure of folding and pressing. On the one hand, this makes the edges smooth, and on the other hand, the double-layer structure has better bending strength.

[0016] As a preferred option, the reinforcing member 6 and the second reinforcing member 7 are rectangular steel pipes, which have excellent bidirectional bending resistance, flat contact surfaces, and fit more closely to support the stepped side plate 4, providing better support effect. They can also be welded and fixed more efficiently, reducing the difficulty of node processing.

[0017] As a preferred embodiment, the surfaces of the channel member 1 and the sealing plate 2 are provided with anti-corrosion layers such as galvanized layer, which have the effect of preventing rust.
