[0002] A prefabricated steel structure refers to a prefabricated building whose structural system is mainly composed of steel components. The prefabricated steel structure is mainly composed of various steel sections, steel plates, steel columns, etc. In order to improve the stability of the assembled prefabricated steel structure, it usually needs to have a protection function. For example, a steel structure prefabricated building for construction engineering with the publication number CN219219360U includes a steel body and a mounting rod. There are two steel bodies. An installation sleeve is provided on the front side of the steel body. One end of the installation sleeve is threadedly connected with a fastening sleeve. A connecting plate is fixedly connected to the front side of one of the installation sleeves, and a connecting sleeve is fixedly connected to the front side of the other installation sleeve. The side of the connecting sleeve close to the connecting plate is open. An I-shaped groove is opened on the upper surface of the steel body. A plurality of springs are fixedly connected to the bottom wall of the I-shaped groove. The top ends of the springs are fixedly connected with an I-shaped plate. An installation plate is fixedly connected to the upper surface of the I-shaped plate. It is not only convenient for disassembly and assembly, but also can be fixed according to the distance between different steel bodies. Since the length is adjustable and it is easy to disassemble, it is convenient for transportation and can be better fixed, and it can also play a role in anti-smashing protection. However, the steel structure prefabricated building for construction engineering still has the following disadvantages in actual use:

[0003] The self-protection performance of traditional prefabricated steel structures is poor. After different structures are assembled, the steel structure is prone to deformation under extrusion, and most of the different structures are fixedly installed, which is not convenient to adjust the position again according to needs after installation. In view of the above problems, it is urgent to innovate and design on the basis of the original prefabricated steel structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a prefabricated steel structure for construction engineering with a protection function, so as to solve the problems put forward in the above background technique that the self-protection performance of traditional prefabricated steel structures is poor. After different structures are assembled, the steel structure is prone to deformation under extrusion, and most of the different structures are fixedly installed, which is not convenient to adjust the position again according to needs after installation.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A prefabricated steel structure for construction engineering with a protection function includes a U-shaped steel. A connecting plate is sleeved outside the U-shaped steel. A through groove is opened on the connecting plate outside the U-shaped steel. And the connecting plate and the U-shaped steel form a sliding structure through the through groove.

[0006] It further includes: moving wheels, which are arranged inside the through groove. Limit mechanisms are arranged at both ends of the U-shaped steel, and the limit mechanisms are used for locking between the U-shaped steel and the connecting plate. The limit mechanisms are interconnected with the protection mechanism, and the protection mechanism is arranged inside the U-shaped steel, and the protection mechanism is used to enhance the strength of the U-shaped steel.

[0007] Preferably, the moving wheels and the connecting plate are rotatably connected, and the surface of the moving wheels is in close contact with the inner side of the U-shaped steel. When the connecting plate moves outside the U-shaped steel, it can drive the moving wheels to roll to improve the smoothness of the movement.

[0008] Preferably, the limit mechanism includes adjusting rods penetrating through both ends of the connecting plate, and the adjusting rods are slidably connected to the connecting plate. After the adjusting rods pass through the limit holes, the stability of the connecting plate outside the U-shaped steel can be ensured.

[0009] Preferably, a spring for resetting is wound around the outer side of the adjusting rod, and a limit plate is fixedly sleeved at the end of the adjusting rod, and the edge of the limit plate is in sliding fit with the inner wall of the connecting plate. Through the fit between the limit plate and the U-shaped steel, the stability of the connecting plate can be further ensured.

[0010] Preferably, the end of the adjusting rod is in snap fit with the limit hole, and the limit holes are evenly distributed on the outside of the U-shaped steel.

[0011] Preferably, the protection mechanism includes a movable plate arranged inside the U-shaped steel, and the edge of the movable plate is in close connection with the inner wall of the fixed cavity. The fixed cavity is arranged inside the U-shaped steel, and the movable plate is interconnected with the inner wall of the fixed cavity through a spring.

[0012] Preferably, a connecting rod is fixed on the top side of the movable plate, and a fixing hole is reserved on the U-shaped steel outside the connecting rod, and the connecting rod passes through the fixing hole, and a threaded groove is arranged on the outer surface of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are: for the prefabricated steel structure for building engineering with a protection function, after the different structures are assembled, the installation position can be adjusted again to meet different installation requirements, and after the steel structure is assembled, its overall strength can be improved, and the phenomenon of deformation due to extrusion can be reduced. The specific content is as follows:

[0014] 1. Move the connecting plate to different positions of the U-shaped steel according to the assembly requirements, and then release the pulling of the adjusting rod. Through the resilience of the spring, the adjusting rod passes through the corresponding limit holes, thereby ensuring the stability of the position of the connecting plate on the U-shaped steel. Through the elasticity of the spring, the limit plate can also be in close contact with the U-shaped steel to further ensure the stability of the position of the connecting plate;

[0015] 2. After the adjusting rod passes through the inner part of the limit hole, it can contact the movable plate and push it to slide within the U-shaped steel. After the movable plate moves, it drives the connecting rod to pass through the fixing hole. Since the outer surface of the connecting rod is provided with a threaded groove, after the two connecting rods extend, it is convenient to connect them to other steel structures, thereby enhancing the strength of the upper end of the U-shaped steel.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 5 , the present invention provides the following technical solutions:

[0024] Embodiment 1: To solve the problems existing in the prior art, therefore, in this embodiment, through the following technical solutions, a prefabricated steel structure for building engineering with a protection function includes a U-shaped steel 1. A connecting plate 2 is sleeved outside the U-shaped steel 1, and a through groove 3 is opened on the connecting plate 2 outside the U-shaped steel 1. Moreover, the connecting plate 2 and the U-shaped steel 1 form a sliding structure through the through groove 3; it further includes: a moving wheel 4, which is arranged inside the through groove 3. Limiting mechanisms are arranged at both ends of the U-shaped steel 1, and the limiting mechanisms are used for locking between the U-shaped steel 1 and the connecting plate 2. The limiting mechanisms are connected to the protection mechanism, and the protection mechanism is arranged inside the U-shaped steel 1, and the protection mechanism is used to enhance the strength of the U-shaped steel 1.

[0025] Most of the existing prefabricated steel structures are fixedly installed between different structures, which is not convenient to adjust the position again according to requirements after installation. For example Figures 1 - 4 As shown, the moving wheel 4 and the connecting plate 2 are rotatably connected, and the surface of the moving wheel 4 is in close contact with the inner side of the U-shaped steel 1; the limiting mechanism includes adjusting rods 5 penetrating through both ends of the connecting plate 2, and the adjusting rods 5 and the connecting plate 2 are slidably connected; a spring for resetting is wound around the outer side of the adjusting rod 5, and a limiting plate 6 is fixedly sleeved at the end of the adjusting rod 5, and the edge of the limiting plate 6 is in sliding contact with the inner wall of the connecting plate 2; the end of the adjusting rod 5 is snap-connected with the limiting hole 7, and the limiting holes 7 are equally spaced on the outer side of the U-shaped steel 1; first, pull the two adjusting rods 5 to make the distance between the two adjusting rods 5 greater than the width of the U-shaped steel 1, then sleeved the connecting plate 2 on the outer side of the U-shaped steel 1 through the through groove 3, move the connecting plate 2 to different positions of the U-shaped steel 1 according to the assembly requirements, and then release the pull on the adjusting rod 5. The resilience of the spring can drive the adjusting rod 5 to slide on the connecting plate 2, so that the adjusting rod 5 passes through the corresponding limiting hole 7, thereby ensuring the stability of the position of the connecting plate 2 on the U-shaped steel 1. After the adjusting rod 5 passes through the limiting hole 7, the elasticity of the spring can also make the limiting plate 6 fit with the U-shaped steel 1, further ensuring the stability of the position of the connecting plate 2. When it is necessary to adjust the position of the connecting plate 2, just pull the adjusting rod 5. When the connecting plate 2 rises and falls, it can drive the moving wheel 4 to slide on the U-shaped steel 1, which can improve the smoothness during its lifting and lowering.

[0026] Embodiment 2: The existing prefabricated steel structure has poor self-protection performance. After the assembly of different structures is completed, the steel structure is prone to deformation when being squeezed. And, therefore, this embodiment adopts the following technical solutions, such as Figure 2 and Figure 5 As shown, the protection mechanism includes a movable plate 9 arranged in the U-shaped steel 1, and the edge of the movable plate 9 is in close connection with the inner wall of the fixed cavity 8, and the fixed cavity 8 is arranged in the U-shaped steel 1. At the same time, the movable plate 9 is connected to the inner wall of the fixed cavity 8 through a spring; a connecting rod 10 is fixed on the top side of the movable plate 9, and a fixing hole 11 is reserved on the U-shaped steel 1 outside the connecting rod 10, and the connecting rod 10 passes through the fixing hole 11. At the same time, a thread groove is arranged on the outer surface of the connecting rod 10; after the adjusting rod 5 passes through the inside of the limiting hole 7, it can contact the movable plate 9 and push the movable plate 9 to slide in the U-shaped steel 1. After the movable plate 9 moves, it drives the connecting rod 10 to pass through the fixing hole 11. Since a thread groove is arranged on the outer surface of the connecting rod 10, when the two connecting rods 10 extend out, it is convenient to connect them to other steel structures, which can improve the strength of the upper end of the U-shaped steel 1 and will not easily deform when being squeezed.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
