Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a steel structure for preventing hollowing and cracking of wall surfaces. Background Technology

[0002] Steel structure buildings are buildings with load-bearing structures made of steel. They are usually composed of beams, columns, trusses and other components made of steel sections and plates. Together with the roof, floors and walls, they form an integrated building. Because the components can be manufactured in factories and installed on site, the construction period is greatly reduced, and they are widely used in industrial and civil buildings.

[0003] In existing technologies, adding a mesh layer to the protective coating on the wall can effectively prevent the wall from becoming hollow and cracked. Steel structural components are spliced ​​together by welding, bolting and other methods to form a stable wall structure. However, existing steel structural components are difficult to limit during splicing, which can easily lead to splicing misalignment. This results in the surfaces of two adjacent steel structural components not being on the same horizontal plane, affecting the overall stability. Utility Model Content

[0004] The purpose of this utility model is to provide a steel structure for preventing hollowing and cracking of the wall, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel structure for preventing hollowing and cracking of a wall, comprising: a wall and steel components, with mounting bolts connecting the wall and steel components, a first protective coating and a second protective coating being provided on the surface of the wall near the steel components, and a mesh layer being provided between the first protective coating and the second protective coating.

[0006] A plug-in post is installed at one edge of the steel component, and a corresponding plug-in groove is opened at the other end of the steel component. A positioning plug is installed in the middle of one end of the steel component, and a positioning groove is opened in the middle of the other end of the steel component. Two limiting rods are symmetrically installed on the inner wall of the positioning groove.

[0007] The inner wall of the positioning groove has two corresponding contraction grooves. Guide rods are installed inside the two contraction grooves. Guide holes are opened on the surface of the two limiting rods near the adjacent guide rods. Movable plates are installed at the ends of the two limiting rods that are far apart from each other. Limiting springs are connected to one end of the two movable plates.

[0008] Preferably, the longitudinal section of the steel component is T-shaped, and several reinforcing plates are uniformly installed inside the steel component, each reinforcing plate being triangular.

[0009] Preferably, a plurality of mounting bolts are evenly distributed, and the wall and steel components are fixedly connected by each mounting bolt, with mounting holes corresponding to the surface of the steel components near each mounting bolt.

[0010] Preferably, three plug-in posts are provided and fixedly installed at one end of the steel component, and the other end of the three plug-in posts is an arc surface.

[0011] Preferably, the positioning plug has an isosceles trapezoidal cross section, and a positioning rod is fixedly connected to one end of the positioning plug. One end of the positioning rod is fixedly installed in the middle of one end of the steel component.

[0012] Preferably, both limiting rods are T-shaped, the outer walls of both limiting rods are slidably connected to the inner walls of adjacent shrinkage grooves, the ends of the two limiting rods that are far apart from each other are fixedly connected to adjacent movable plates, the inner walls of the two shrinkage grooves near the movable plates are respectively provided with movable grooves, and the two movable plates are slidably installed in adjacent movable grooves.

[0013] Preferably, one end of each of the two limiting springs is fixedly connected to an adjacent movable plate, the other end of each of the two limiting springs is fixedly installed on the inner wall of an adjacent movable groove, and the two limiting springs are sleeved on the end of an adjacent limiting rod near the movable plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a plug-in post at one end of a steel component to insert into the plug-in slot of an adjacent steel component, facilitating initial positioning during steel component assembly. A guide rod installed inside the shrinkage groove guides the positioning rod as it moves within the shrinkage groove. When the positioning plug is inserted into the positioning slot and presses against the positioning rod, a limiting spring connected to one end of the moving plate resets the positioning rod and limits the positioning plug, thus facilitating further positioning of the steel components and preventing misalignment during assembly. This ensures that the surfaces of two adjacent steel structural components are on the same horizontal plane, preventing any impact on overall stability. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a steel structure for preventing hollowing and cracking of a wall, comprising: a wall body 1 and a steel component 5, with mounting bolts 7 connecting the wall body 1 and the steel component 5. A first protective coating 2 and a second protective coating 4 are provided on the surface of the wall body 1 near the steel component 5. A mesh layer 3 is provided between the first protective coating 2 and the second protective coating 4. One side of the mesh layer 3 is glued to the first protective coating 2, and the other end of the mesh layer 3 is coated with the second protective coating 4, making the wall surface less prone to bulging and cracking. The longitudinal section of the steel component 5 is T-shaped, and several reinforcing plates 6 are evenly installed inside the steel component 5. Each reinforcing plate 6 is triangular, which can improve the stability of the steel component 5. Several mounting bolts 7 are evenly arranged, and the wall body 1 and the steel component 5 are fixedly connected by each mounting bolt 7. Mounting holes 8 are correspondingly provided on the surface of the steel component 5 near each mounting bolt 7.

[0025] A plug-in post 10 is installed at one edge of the steel component 5, and a corresponding plug-in groove 9 is opened at the other end of the steel component 5. A positioning plug 14 is installed in the middle of one end of the steel component 5, and a positioning groove 12 is opened in the middle of the other end of the steel component 5. Two limiting rods 13 are symmetrically installed on the inner wall of the positioning groove 12. Three plug-in posts 10 are provided and fixedly installed at one end of the steel component 5, and the other ends of the three plug-in posts 10 are all curved. The positioning plug 14 has an isosceles trapezoidal cross section, and a positioning rod 11 is fixedly connected to one end of the positioning plug 14. One end of the positioning rod 11 is fixedly installed in the middle of one end of the steel component 5. When the positioning plug 14 is fully inserted into the positioning groove 12, it is convenient to limit the positioning plug 14.

[0026] The inner wall of the positioning groove 12 has two corresponding contraction grooves 17. Guide rods 16 are installed inside the two contraction grooves 17. Guide holes 15 are formed on the surfaces of the two limiting rods 13 near the adjacent guide rods 16. Movable plates 18 are installed at the ends of the two limiting rods 13 that are far apart from each other. Limiting springs 20 are connected to one end of each movable plate 18. Both limiting rods 13 are T-shaped. The outer walls of both limiting rods 13 are slidably connected to the inner walls of the adjacent contraction grooves 17. The ends of both limiting rods 13 that are far apart from each other are fixedly connected to the adjacent movable plates 18. Movable grooves 19 are correspondingly formed on the inner walls of the two contraction grooves 17 near the movable plates 18. The two movable plates 18 are slidably installed in the adjacent movable grooves 19, which can limit the movement of the movable plates 18, allowing them to move only along the movable grooves 19. One end of each of the two limiting springs 20 is fixedly connected to an adjacent movable plate 18, and the other end of each of the two limiting springs 20 is fixedly installed on the inner wall of an adjacent movable groove 19. Both limiting springs 20 are sleeved on the end of an adjacent limiting rod 13 near the movable plate 18. When the positioning plug 14 presses against the limiting rod 13, the limiting spring 20 is compressed. Two guide rods 16 are symmetrically installed inside each of the two shrinkage grooves 17. One end of each guide rod 16 is fixedly installed on the inner wall of one end of the shrinkage groove 17, and the other end of each guide rod 16 slides through an adjacent guide hole 15 and is fixedly installed on the inner wall of the other end of the shrinkage groove 17. These guide rods guide the limiting rod 13 as it moves within the shrinkage groove 17.

[0027] When this device is in operation, when assembling two steel components 5, the insertion post 10 at one end of the steel component 5 can be inserted into the insertion slot 9 of the adjacent steel component 5, which facilitates the initial positioning of the steel component 5. The guide rod 16 installed inside the shrinkage groove 17 guides the limiting rod 13 as it moves within the shrinkage groove 17. When the positioning plug 14 is inserted into the positioning slot 12, it will squeeze the limiting rod 13 to enter the shrinkage groove 17. After the positioning plug 14 is fully inserted into the positioning slot 12, the limiting spring 20 connected to one end of the moving plate 18 can drive the limiting rod 13 to reset and limit the positioning plug 14. At this time, the surface of the limiting rod 13 abuts against one end of the positioning plug 14 and the surface of the positioning rod 11, which facilitates the re-positioning of the steel component 5. This makes it easy to assemble the steel component 5 by welding, bolting, etc., and it is less likely to cause misalignment during assembly. This ensures that the surfaces of the two adjacent steel components 5 are on the same horizontal plane, so as not to affect the overall stability.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
