Description

Technical Field

[0001] This utility model relates to the field of steel beam construction technology, specifically to an H-shaped steel beam covering device. Background Technology

[0002] Prefabricated steel structure buildings, as an important system of modern industrialized construction, replace traditional reinforced concrete structures with steel load-bearing components, offering advantages such as light weight, high strength, excellent seismic performance, and strong adaptability to large-span spaces. Steel structure building systems differ fundamentally from traditional cast-in-place structures in terms of component standardization and structural force transmission mechanisms. Steel beams, as the main horizontal load-bearing components, commonly employ two typical forms: I-beam sections and rectangular closed sections to meet different load requirements. Currently, the commonly used steel beam cladding process involves a multi-layered structure with a welded metal keel base layer, a composite plywood leveling layer, and an outer gypsum board finish. The problems with this cladding process are: numerous construction steps leading to low construction efficiency and high costs; insufficient reliability of mechanical connection nodes, posing a risk of surface layer delamination and detachment; and a cumulative thickness of over 150mm in the structural layers, resulting in low space utilization.

[0034] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, an H-beam covering device is provided for covering the recessed portion of an H-beam 1, comprising: a first fixing member 2 disposed in the recessed portion, the first fixing member 2 having a first assembly portion; and at least one covering component 3 having a second assembly portion that cooperates with the first assembly portion for fixing to one side of the H-beam 1 to close the recessed portion.

[0036] By using the covering component 3 to form a fixed connection with the first fixing member 2 to close the recess of the H-shaped steel beam 1, the operation is simple and quick, with fewer construction steps, high construction efficiency, and low construction cost; it is easy to disassemble for maintenance without damaging the existing structure; the structural connection is reliable and there is no risk of hollowing or falling off; the covering component 3 has a simple structure, high space utilization, and can meet the usage requirements of the building structure; it is convenient for construction site management and has good practicality.

[0037] like Figures 1-3 As shown, in one embodiment, the H-beam 1 is fixed between the wall 4 and the floor slab 5. Alternatively, the H-beam 1 can also be fixed between the column and the floor slab, or between two other adjacent structural members.

[0038] like Figure 2 As shown, in one embodiment, the first fastener 2 is fixed to the inner side of the flange of the H-beam 1. Two first fasteners 2 are provided, each welded and fixed to the inner side of two oppositely arranged flanges; the extension length of the first fastener 2 is the same as the extension length of the H-beam 1. As an alternative embodiment, the first fastener 2 can also be inserted and fixed to the H-beam 1. As another alternative embodiment, the length of the first fastener 2 can be shorter, and multiple first fasteners 2 can be spaced apart on the H-beam 1.

[0039] like Figures 5-7 As shown, in one embodiment, the covering assembly 3 includes: a covering member 31 for abutting against the outside of the H-shaped steel beam 1 to close the recess; and a second fixing member 32 disposed on the side of the covering member 31 near the first fixing member 2, the second fixing member 32 having a second mounting portion. There are two sets of the covering assembly 3 and the first fixing member 2, respectively disposed in two recesses of the H-shaped steel beam. By abutting the outside of the H-shaped steel beam 1, a flat plane can be formed with the side of the H-shaped steel beam 1, facilitating the design and subsequent construction of the overall building structure.

[0040] The cladding component 31 is made of cement fiberboard, and its extension width is the same as the extension height of the H-beam 1. Two second fasteners 32 are provided, welded and fixed to opposite sides of the cladding component 31 respectively. The extension length of the second fasteners 32 is the same as the extension length of the H-beam 1. The cement fiberboard has a length of 2400mm and a thickness of 12mm. As an alternative embodiment, the cladding component 31 can also be made of steel plate or other materials; no further restrictions are placed here. As an alternative embodiment, the size of the cement fiberboard is determined according to the size of the H-beam 1; no further restrictions are placed here. As an alternative embodiment, the second fasteners 32 can also be inserted and fixed to the cladding component 31. As an alternative embodiment, the length of the second fasteners 32 can also be shorter, with multiple second fasteners 32 spaced apart on the cladding component 31.

[0041] like Figures 3-5 As shown, in one embodiment, the first assembly part and the second assembly part are plugged into each other. Specifically, the first fixing member 2 has a groove 21 to form the first assembly part, and the second fixing member 32 has a protrusion 321 to form the second assembly part. The protrusion 321 extends into the groove 21 to form a plug-in connection. The protrusion 321 is an elliptical protrusion, and is provided at 30cm intervals along the length of the second fixing member 32. By plugging the first assembly part and the second assembly part together, installation and disassembly are facilitated, making it more flexible and convenient to use. By providing multiple protrusions 321, the connection strength between the covering component 3 and the first fixing member 2 can be improved. As an alternative implementation, the protrusion 321 can also be provided along the entire length of the second fixing member 32.

[0042] like Figure 4 As shown, in one embodiment, the first fixing member 2 is a triangular structure, with a notch at one of its apex to form a groove 21. One side of the triangular structure is fixed to the inner side of the wing plate, and a notch is formed at the apex where the side and the adjacent side form. Specifically, the cross-section of the triangular structure is a right triangle, with a notch at the apex formed by the longer right-angled side and the hypotenuse. By making the first fixing member 2 a triangular structure and creating a notch at its apex to form a groove 21, it can accommodate protrusions 321 of various sizes and shapes, thus broadening its applicability and making the snap-fit ​​more flexible and convenient. As an alternative implementation, the first fixing member 2 can also be a solid structure, with a cavity on the side near the second fixing member 32 to form the groove 21.

[0043] like Figures 5-7As shown, in one embodiment, the second fastener 32 is an L-shaped structure, with one side of the L-shaped structure fixed to the covering member 31 and the other side having a protrusion 321. The L-shaped structure is fixedly connected to the covering member 31 by self-tapping screws. Along the length of the second fastener 32, two fasteners are arranged in a row at 35cm intervals. By setting the second fastener 32 as an L-shaped structure, the connection stability of the second fastener 32 can be improved. As an alternative implementation, the second fastener 32 can also be a rectangular cross-section, a U-shaped cross-section, or other cross-sectional shapes; no further limitations are imposed here.

[0044] In one embodiment, the construction steps of the H-beam cladding device are as follows:

[0045] Step 1: Weld and fix the first fastener 2 to the inner side of the upper and lower flanges of the H-beam 1;

[0046] Step 2: Secure the two second fasteners 32 to the covering part 31 using self-tapping screws;
