Description

A high-pressure-bearing composite steel structure Technical Field

[0001] This utility model relates to the field of steel components, and more specifically, to a high-pressure-bearing composite steel component. Background Technology

[0002] During the manufacturing of steel components, rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are employed to ensure their quality and durability. Steel has high strength, and compared to concrete and wood, its density-to-yield strength ratio is relatively low. Therefore, under the same stress conditions, steel components have smaller cross-sections and lighter weight, facilitating transportation and installation. Steel has good toughness and plasticity, uniform material properties, and high structural reliability, making it suitable for withstanding impact and dynamic loads and exhibiting good seismic performance. There are many types of steel components, among which box-type steel components are frequently used in construction projects, especially in steel component factory projects. Like H-beams, they are often used as steel beams or columns in steel structures, hence the name box-type columns. Due to their small cross-section, high strength, and high rigidity, they are widely used in high-rise steel structure buildings.

[0003] Box-shaped steel components are mainly welded from four steel plates. Currently, there is a lack of pre-fixing mechanisms when welding box-shaped steel components, which may cause the steel plates to move or deform during the welding process, thus affecting the quality of the weld. Therefore, we have made improvements to this issue and proposed a high-pressure-bearing composite steel component. Summary of the Invention

[0004] In order to solve the problems raised by the above-mentioned utility model, the present utility model provides the following technical solution:

[0005] High-pressure-bearing composite steel components are used to improve the above problems.

[0006] The present invention is as follows:

[0007] The system includes a motherboard, two side plates, a top plate, a mounting plate, and a reinforcing plate. The two side plates are located on top of the motherboard, the top plate is located on top of the side plates, the mounting plate is located at one end of the motherboard, and the reinforcing plate is located on top of the motherboard. A first connecting seat is welded to the top of the motherboard, and the first connecting seat has a first connecting groove on its top. A limit mechanism is provided on the top of the motherboard. A second connecting seat is welded to the inner wall of the side plate, and the second connecting seat has a second connecting groove on its top. A first pre-fixing mechanism is provided on the inner wall of the side plate, and a protrusion is welded to the bottom of the side plate. A second pre-fixing mechanism is provided at the bottom of the top plate.

[0008] As a preferred technical solution of this utility model, the limiting mechanism includes a limiting rod welded to the top of the main board, and the reinforcing plate is located between the limiting rods.

[0009] As a preferred technical solution of this utility model, the first pre-fixing mechanism includes an L-shaped pre-fixing rod welded to the side wall of the side plate, and the L-shaped pre-fixing rod is adapted to the first connecting groove.

[0010] As a preferred technical solution of this utility model, the second pre-fixing mechanism includes a rectangular pre-fixing rod welded to the bottom of the top plate, and the rectangular pre-fixing rod is adapted to the second connecting groove.

[0011] As a preferred technical solution of this utility model, a circular groove is provided on the top of the motherboard, and the circular groove is adapted to the protrusion.

[0012] As a preferred technical solution of this utility model, the mounting plate is provided with through holes evenly distributed.

[0013] As a preferred technical solution of this utility model, the main board, two side plates, the top plate, the mounting plate, and the reinforcing plate are all fixedly connected by welding.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] 1. By pre-fixing the side plate onto the main plate, inserting the L-shaped pre-fixing rod on the side plate into the first connecting groove on the first connecting seat, and simultaneously inserting the protrusion at the bottom of the side plate into the circular groove, the pre-fixation of the side plate is completed. Next, the reinforcing plate is placed between the limiting rods. Then, the top plate is pre-fixed onto the top of the side plate, inserting the rectangular pre-fixing rod at the bottom of the top plate into the second connecting groove on the second connecting seat, and then welding the top plate. This ensures that the steel plate is accurately positioned before welding, thus improving welding precision and reducing operational risks during welding. Because the steel plate is fixed, workers can perform welding operations more safely. This solves the problem in existing technologies where the lack of a pre-fixing mechanism during welding of box-shaped steel components can lead to movement or deformation of the steel plate during welding, affecting weld quality.

[0030] Example:

[0031] As shown in Figures 1-6, this embodiment proposes a high-pressure-bearing composite steel structure, including a main plate 1, two side plates 2, a top plate 3, a mounting plate 4, and a reinforcing plate 5. The two side plates 2 are positioned on top of the main plate 1, the top plate 3 is positioned on top of the side plates 2, the mounting plate 4 is positioned at the end of the main plate 1, and the reinforcing plate 5 is positioned on top of the main plate 1. The reinforcing plate 5, after welding, improves the overall strength of the steel structure. A first connecting seat 101 is welded to the top of the main plate 1, and a first connecting groove 102 is formed on the top of the first connecting seat 101. The main board 1 has a limiting mechanism at its top, which limits the reinforcing plate 5. The inner wall of the side plate 2 is welded with a second connecting seat 201. The top of the second connecting seat 201 has a second connecting groove 202, which serves as a pre-connection mechanism. The inner wall of the side plate 2 is provided with a first pre-fixing mechanism, which cooperates with the first connecting groove 102. The bottom of the side plate 2 is welded with a protrusion 204. The bottom of the top plate 3 is provided with a second pre-fixing mechanism, which cooperates with the second connecting groove 202.

[0032] The limiting mechanism includes a limiting rod 103 welded to the top of the main board 1, and a reinforcing plate 5 located between the limiting rods 103. The limiting rods 103 facilitate the fixing of the reinforcing plate 5 and make welding work easier.

[0033] The first pre-fixing mechanism includes an L-shaped pre-fixing rod 203 welded to the side wall of the side plate 2. The L-shaped pre-fixing rod 203 is adapted to the first connecting groove 102, so that the L-shaped pre-fixing rod 203 on the side plate 2 is inserted into the first connecting groove 102 of the first connecting seat 101.

[0034] The second pre-fixing mechanism includes a rectangular pre-fixing rod 301 welded to the bottom of the top plate 3. The rectangular pre-fixing rod 301 is adapted to the second connecting groove 202, so that the rectangular pre-fixing rod 301 at the bottom of the top plate 3 is inserted into the second connecting groove 202 on the second connecting seat 201.

[0035] A circular groove 104 is provided on the top of the motherboard 1. The circular groove 104 is adapted to the protrusion 204, so that the protrusion 204 at the bottom of the side plate 2 is inserted into the circular groove 104.

[0036] Through holes 401 are evenly provided on the mounting plate 4. The through holes 401 are used to install the steel component with bolts during installation.

[0037] The main board 1, two side plates 2, top plate 3, mounting plate 4, and reinforcing plate 5 are all fixedly connected by welding.

[0038] Specifically, when using this high-pressure-bearing composite steel structure: first, place the main plate 1 on a flat surface, then pre-fix the side plate 2 onto the main plate 1, inserting the L-shaped pre-fixing rod 203 on the side plate 2 into the first connecting groove 102 on the first connecting seat 101, and simultaneously inserting the protrusion 204 at the bottom of the side plate 2 into the circular groove 104, thus completing the pre-fixation of the side plate 2. At this point, the side plate 2 can be welded. Next, place the reinforcing plate 5 between the limiting rods 103, and then weld the reinforcing plate 5. Then, pre-fix the top plate 3 onto the top of the side plate 2, inserting the rectangular pre-fixing rod 301 at the bottom of the top plate 3 into the second connecting groove 202 on the second connecting seat 201, and then weld the top plate 3. Finally, weld the mounting plate 4. This ensures that the steel plate is accurately positioned before welding, thereby improving welding precision and reducing the risk of operator error during welding, as the steel plate is already fixed, allowing workers to perform welding operations more safely.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
