Description

Technical Field

[0001] This utility model relates to the field of prefabricated steel structure technology, specifically a prefabricated steel structure for building corrosion protection. Background Technology

[0002] Prefabricated steel structure is a building structure that is assembled and connected on the construction site using steel structure components that are manufactured in a factory.

[0003] For example, the Chinese authorized patent with publication number CN221298212U (A Prefabricated Cross-Column Steel Structure) includes vertical steel columns and several horizontal steel columns. Multiple faces of the vertical steel columns are provided with rectangular frames, and a horizontal steel column is inserted into each rectangular frame. In this invention, by inserting several horizontal steel columns into the rectangular frames on the multiple faces of the vertical steel columns, several positioning posts on the end faces of the horizontal steel columns are inserted into several positioning holes corresponding to those on the inner sides of the rectangular frames. Then, guide strips on the sides of the horizontal steel columns extend into corresponding guide grooves on the inner walls of the rectangular frames, causing the screw holes on the surface of the horizontal steel columns to match the corresponding through holes on the outer surface of the rectangular frames. At this point, bolts are threaded through the through holes and screw holes of the rectangular frames, achieving efficient assembly of the vertical steel columns and several horizontal steel columns. Combined with the "king"-shaped reinforcing ribs on the outer surface of the rectangular frames and the triangular plates welded between adjacent rectangular frames, it has the advantage of reliable connection.

[0004] However, in existing prefabricated steel structures, the crossbeams and columns are fixed with bolts during assembly, resulting in a single stress point. The crossbeams are prone to bending and damage at the connection with the columns, leading to low stress resistance. Therefore, this does not meet the current requirements. To address this, we propose a prefabricated steel structure for building corrosion protection. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated steel structure for building corrosion protection, so as to solve the problem mentioned in the background art that the existing prefabricated steel structures rely on bolts to fix the crossbeams and columns during assembly, resulting in a single stress position, and the crossbeams are prone to bending and damage at the connection with the columns, leading to low stress resistance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated steel structure for building corrosion protection, comprising: a column, wherein the column is hollow inside, a stabilizing component is provided inside the top of the column, installation notches are provided on all four sides of the column near the top, a crossbeam is provided around the stabilizing component, a connecting socket is provided at one end of the crossbeam, and a reinforcing component is provided at the upper end of the stabilizing component.

[0007] Preferably, the stabilizing component includes a base plate, the upper surface of which is provided with an inner groove, a stabilizing seat is provided at the center of the bottom surface of the inner groove, the upper surface of the stabilizing seat is provided with a threaded groove, and the four sides of the stabilizing seat are provided with connecting slots, and a connecting socket is inserted into the connecting slot, and both the connecting socket and the connecting slot are T-shaped.

[0008] Preferably, the stabilizing component further includes an anti-fall top plate, which is welded and fixed to the upper surface of the base plate around the perimeter. The inner walls of the inner groove are provided with fixing bolts, and the inner walls of the column near the top are provided with threaded holes. One end of the fixing bolt passes through the base plate and is threadedly connected to the threaded hole.

[0009] Preferably, the reinforcing component includes a reinforcing cover plate, the upper surface of which is provided with a safety groove 8, one end of which is into which a fastener 18 is inserted, and one end of the fastener 18 passes through the safety groove 8 and is threadedly connected to the threaded groove 17.

[0010] Preferably, the reinforcing component further includes connecting legs, and four connecting legs are provided, with the four connecting legs respectively located on the lower surface of the four corners of the reinforcing cover plate.

[0011] Preferably, the outer surfaces of the columns, stabilizing components, crossbeams, and reinforcing components are all coated with an anti-corrosion coating.

[0012] Preferably, fixing plates are provided on both sides of the bottom end of the column, and the fixing plates are welded and fixed to the column.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model is a prefabricated steel structure composed of columns, stabilizing components, crossbars and reinforcing components. When installing the crossbars, the connecting socket is inserted into the connecting slot. Since both the connecting socket and the connecting slot are T-shaped, they are not easy to fall off after connection. Then, the reinforcing cover is placed on the stabilizing component and fixed with fasteners. The reinforcing cover presses down on the connection between the crossbar and the stabilizing component to prevent the edge from warping, thus improving safety and stability. In this way, when the crossbar is under stress, it is not just the connection between the crossbar and the column that bears the stress. The pressure is shared by the stabilizing component and the reinforcing component, which increases the stress on the end of the crossbar and makes it less prone to bending and damage. This improves the stability and safety of the prefabricated steel structure composed of columns, stabilizing components, crossbars and reinforcing components. In addition, the anti-corrosion coating increases the service life of the prefabricated steel structure. This solves the problem that in the existing prefabricated steel structure, the crossbar and the column are fixed by bolts, the stress position is singular, and the crossbar is prone to bending and damage at the connection with the column, resulting in low stress.

[0015] (2) By installing anti-fall top plates on all four sides of the base plate, the lower surface of the anti-fall top plate contacts the upper surface of the installation notch when the base plate is installed, which provides support, prevents the base plate from falling, improves the stability of the base plate installation, and makes it less likely to slip along the internal cavity of the column, making it easy to install and disassemble.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-5This utility model provides an embodiment of a prefabricated steel structure for building corrosion protection, comprising: a column 1, the column 1 being hollow inside; a stabilizing component 2 being disposed inside the top of the column 1; mounting notches 9 being provided on all four sides of the column 1 near the top; crossbeams 3 being disposed around the stabilizing component 2; a connecting socket 19 being disposed at one end of the crossbeams 3; a reinforcing component 4 being disposed at the upper end of the stabilizing component 2; the stabilizing component 2 including a base plate 11; an inner groove 12 being provided on the upper surface of the base plate 11; a stabilizing seat 13 being disposed at the center of the bottom surface of the inner groove 12; connecting slots 14 being provided on all four sides of the stabilizing seat 13; and the connecting socket 19 being inserted into the connecting slot 14 and connected to the socket. Both the base 19 and the connecting slot 14 are T-shaped. The stabilizing component 2 also includes an anti-fall top plate 15, which is welded and fixed to the upper surface of the base plate 11. The inner walls of the inner groove 12 are provided with fixing bolts 16. The inner walls of the column 1 near the top are provided with threaded holes 10. One end of the fixing bolt 16 passes through the base plate 11 and is threaded into the threaded hole 10, so that the base plate 11 is inserted into the column 1. The lower surface of the anti-fall top plate 15 contacts the upper surface of the mounting notch 9 to provide support and prevent the base plate 11 from falling. One end of the fixing bolt 16 passes through the base plate 11 and is threaded into the threaded hole 10 to fix the base plate 11, which in turn fixes the stabilizing component 2.

[0024] Then install the horizontal frame 3. During installation, insert the connecting socket 19 into the connecting slot 14. Since both the connecting socket 19 and the connecting slot 14 are T-shaped, they are not easy to fall off after connection. Then, fix the connection between the horizontal frame 3 and the column 1 with bolts using the existing fixing method (not shown in the figure).

[0025] The reinforcing component 4 includes a reinforcing cover plate 6. A safety groove 8 is provided on the upper surface of the reinforcing cover plate 6, and a fastener 18 is inserted into one end of the safety groove 8. A threaded groove 17 is provided on the upper surface of the stabilizing base 13, and one end of the fastener 18 passes through the safety groove 8 and is threadedly connected to the threaded groove 17. The reinforcing component 4 also includes connecting legs 7, and four connecting legs 7 are provided, located on the lower surface of the four corners of the reinforcing cover plate 6. The outer surfaces of the column 1, stabilizing component 2, crossbeam 3, and reinforcing component 4 are all coated with an anti-corrosion coating 20, which is a polyurethane topcoat. After fixing the crossbeam 3, the reinforcing cover plate 6 is placed on the stabilizing component 2, and the connecting legs 7 are inserted into the gap between the stabilizing base 13 and the column 1. The filling process stabilizes the reinforcing cover plate 6, preventing positional displacement. One end of the fastener 18 passes through the safety groove 8 and is threaded into the threaded groove 17, thus fixing the reinforcing cover plate 6. This process also applies downward pressure to the connection between the crossbeam 3 and the stabilizing component 2, preventing warping and improving safety and stability. When the crossbeam 3 is under stress, the stress is not solely borne at the connection between the crossbeam 3 and the column 1, but is also shared by the stabilizing component 2 and the reinforcing component 4. This increases the stress on the end of the crossbeam 3, making it less prone to bending and damage. This improves the stability and safety of the prefabricated steel structure composed of the column 1, stabilizing component 2, crossbeam 3, and reinforcing component 4, and the anti-corrosion coating 20 extends the service life of the prefabricated steel structure.

[0026] Please see Figure 1 Both sides of the bottom end of the column 1 are provided with fixing plates 5, and the fixing plates 5 are welded to the column 1. The column 1 is fixed to the ground by external bolts of the fixing plates 5.
