Description

Technical Field

[0001] The utility model relates to the technical field of light steel buildings, in particular to a prefabricated light steel building structure. Background Technique

[0002] The prefabricated light steel building structure is a modern building technology that uses light steel as the main load-bearing structure material and constructs buildings through factory prefabrication and on-site assembly. It mainly consists of light steel keels, wall systems, roof systems, and floor systems. The components of the prefabricated light steel building are prefabricated in the factory, and only assembly is required on-site, which greatly shortens the construction period. The materials are light in weight but high in strength, can bear large loads, are suitable for multi-story and large-span buildings, and the light steel materials can be recycled. At the same time, good heat insulation performance helps to save energy and reduce emissions.

[0003] The installation process of the wall system of the prefabricated light steel building involves multiple steps, from factory prefabrication to on-site assembly. Workers assemble the wall frame using light steel materials in the factory according to the wall size and design requirements, fix the reinforcing light steel inside the frame, and then these prefabricated wall frames are transported to the construction site. At the construction site, workers first move the wall frame to the predetermined position and require the installation holes on the frame to be precisely aligned with the jacks reserved in advance on the cement floor. Then, workers need to establish a connection between the frame and the ground. In this process, workers must manually hold the frame and at the same time operate connectors such as bolts to fix it to the ground. This process not only tests the physical strength and patience of the workers, but also increases the construction time and reduces the overall efficiency. In addition, due to the weight and size of the frame, it is often difficult to maintain the absolute stability of the frame for a long time manually. Especially in an environment with strong wind or uneven ground, the wall frame may tilt, affecting the verticality of the structure. During the splicing process of multiple walls, in order to prevent the wall from tilting, workers usually need to find temporary supports such as light steel or wooden strips of appropriate length to support the wall. This method of finding support materials on-site has many problems. First, the length and strength of the support materials may not be consistent, and they cannot provide uniform and stable support. Second, the placement position and angle of the support depend on the experience judgment of the workers, lacking a standardized operation process, which is likely to lead to poor support effects. Moreover, using non-standard support materials may also introduce new safety hazards, such as the quality problems of the support itself or the insecure fixing method, which may cause accidents during the construction process.

[0004] In summary, the inaccurate installation and unstable support of the wall frame directly affect the overall structural safety and service life of the prefabricated light steel building. On the other hand, due to the low efficiency and high cost of manual operation, the total cost of the project is increased, the construction period is prolonged, and the economic advantage of the prefabricated building compared with the traditional building method is reduced.

[0005] Therefore, it is necessary to design a prefabricated light steel building structure to solve the above problems. Summary of the Invention

[0006] The purpose of the present utility model is to solve the deficiencies existing in the prior art, and a prefabricated light steel building structure is proposed.

[0007] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0008] A prefabricated light steel building structure includes a frame. A number of mutually parallel cross plates are fixedly connected to the inner side of the frame. A number of fixing holes are opened on the inner bottom surface of the frame. A number of connecting plates are fixedly connected to the inner top surface of the frame. The bottom ends of the connecting plates sequentially penetrate through all the cross plates. The connecting plates are fixed to the cross plates and the inner bottom surface of the frame respectively, and are perpendicularly arranged between the connecting plates and the cross plates. Two support components are provided on both sides of the frame, and the two support components are symmetrically arranged.

[0009] As a preferred technical solution of the present utility model, the support component includes a fixing frame fixedly connected to the inner top surface of the frame. A sleeve is rotatably connected to the inner side of the fixing frame. A screw rod is threadedly connected to the inside of the sleeve. The bottom end of the screw rod extends to the outside of the sleeve, and a pressing plate is provided at the bottom of the screw rod. A connecting groove is opened on the pressing plate. A rotatable connecting ball is provided inside the connecting groove, and the connecting ball is fixed to the bottom end of the screw rod. A slot adapted to the sleeve is provided on the cross plate.

[0010] As a preferred technical solution of the present utility model, a placing groove is provided on the inner bottom surface of the frame, and the placing groove is adapted to the pressing plate. Two insertion holes one are penetrated through the inner bottom surface of the placing groove. Two insertion holes two are penetrated through the pressing plate, and the positions of the insertion holes one and the insertion holes two correspond to each other.

[0011] As a preferred technical solution of the present utility model, an anti-slip pad is provided inside the connecting groove.

[0012] As a preferred technical solution of the present utility model, a number of pointed blocks are provided at the bottom of the pressing plate, and the cross section of the pointed block is in an inverted triangular structure.

[0013] As a preferred technical solution of the present utility model, a number of obliquely arranged fastening plates are fixed at the partial intersections of the cross plates and the connecting plates.

[0014] The present utility model has the following beneficial effects:

[0015] 1. Improve installation accuracy: By using an adjustable screw and pressing plate system, the connection between the frame and the ground can be precisely controlled to ensure the verticality and flatness of the frame, thereby improving the installation accuracy of the entire prefabricated light steel building. This also reduces the time and cost of frame adjustment or modification, simplifies the installation process and assembly difficulty.

[0016] 2. Enhance structural stability: The use of support components, especially the close contact between the pressing plate and the ground and the triangular support structure, significantly enhances the stability of the frame, and can maintain the firmness of the structure even under adverse construction conditions. The support components can not only provide temporary support but also serve as a permanent reinforcement structure after installation, increasing the load-bearing capacity of the frame and the stability of the overall building.

[0017] 3. Reduce labor intensity: The support system reduces the physical burden on construction workers, eliminating the need for manual long-term support of the frame, improving work efficiency, reducing labor costs. The fast support and fixing mechanism shortens the frame installation time, making the entire construction process more efficient and helping to speed up the project progress.

[0018] 4. Adapt to different construction environments: The adjustable length of the screw allows the support components to adapt to different heights and terrain conditions, ensuring stable support in various construction environments. The ingenious design of the support components allows them to be stored inside the frame when not needed, reducing the occupation of extra space and facilitating transportation and on-site operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Referring to Figures 1-4 , a prefabricated light steel building structure includes a frame 1, which is assembled and fixed by four light steels through bolts or welding. A number of mutually parallel cross plates 3 are fixedly connected to the inner side of the frame 1. A number of fixing holes 2 are opened on the inner bottom surface of the frame 1. During the construction process, connecting members such as threaded rods are embedded in the cement floor, and the positions of the connecting members correspond to those of the fixing holes 2. During assembly, the frame 1 is moved to a suitable position, and the connecting members such as threaded rods are passed through the fixing holes 2, and tools such as nuts are used to fix the frame 1. A number of connecting plates 4 are fixedly connected to the inner top surface of the frame 1. The connecting plates 4 and the cross plates 3 serve to strengthen the frame 1. The bottom ends of the connecting plates 4 sequentially penetrate through all the cross plates 3, and the connecting plates 4 are arranged at equal intervals. The connecting plates 4 are respectively fixed to the cross plates 3 and the inner bottom surface of the frame 1, and are perpendicular to each other between the connecting plates 4 and the cross plates 3. Obliquely arranged fastening plates 17 are fixed at some intersections of the cross plates 3 and the connecting plates 4. All the fastening plates 17 are divided into several columns. In each column, two adjacent fastening plates 17 form a horizontal V-shaped structure. The fastening plates 17 can improve the bearing capacity of the frame 1 and ensure the stability of the prefabricated light steel building structure. Two support assemblies are provided on both sides of the frame 1, and the two support assemblies are symmetrically arranged. Further, the number of support assemblies on both sides can be designed according to the length of the frame 1. When the frame 1 is relatively long, multiple support assemblies can be provided to improve the stability of the frame 1, thereby improving the accuracy of building assembly.

[0026] Referring to Figures 1-4 , the support assembly includes a fixing frame 5 fixedly connected to the inner top surface of the frame 1. The fixing frame 5 has an inverted U-shaped structure and can be fixed to the inner top surface of the frame 1 by bolts. A sleeve 6 is rotatably connected to the inner side of the fixing frame 5. A screw rod 7 is threadedly connected to the inside of the sleeve 6. The bottom end of the screw rod 7 extends outside the sleeve 6, and a pressing plate 8 is provided at the bottom of the screw rod 7. A number of pointed blocks 16 are provided at the bottom of the pressing plate 8, and the cross section of the pointed blocks 16 is an inverted triangular structure. The pointed blocks 16 play an anti-slip role to ensure the stability of the contact between the pressing plate 8 and the ground. A connecting groove 9 is opened on the pressing plate 8, and a rotatable connecting ball 10 is provided inside the connecting groove 9. The connecting ball 10 can freely rotate in any direction inside the connecting groove 9, and the connecting ball 10 is fixed to the bottom end of the screw rod 7. A slot 11 adapted to the sleeve 6 is provided on the cross plate 3, and the sleeve 6 can be located inside the slot 11, which enables the sleeve 6 to be perpendicular to the inner bottom surface of the frame 1, thereby realizing the storage of the sleeve 6 and preventing the sleeve 6 from being in an inclined state and increasing the space of the frame 1. An anti-slip pad 15 is provided inside the connecting groove 9, and the anti-slip pad 15 can increase the friction between the connecting ball 10 and the connecting groove 9 and improve the stability of the support of the screw rod 7 and the sleeve 6 on the frame 1.

[0027] Referring to Figure 3, a placement groove 12 is provided on the inner bottom surface of the frame 1, and the placement groove 12 is adapted to the pressure plate 8. When the frame 1 does not need to be supported, the pressure plate 8 can be received into the placement groove 12. Two first jacks 13 are provided through the inner bottom surface of the placement groove 12, and two second jacks 14 are provided through the pressure plate 8, and the positions of the first jack 13 and the second jack 14 correspond to each other. Connectors can be pre-embedded on the cement ground, and the connectors are aligned with the first jack 13 and the second jack 14, so that the sleeve 6 and the frame 1 can be fixed together. The sleeve 6 plays a role in strengthening and fastening the frame 1 in the vertical direction, and at the same time increases the stability of the connection between the frame 1 and the ground.

[0028] The specific working principle of the present utility model is as follows:

[0029] During assembly, the staff moves the frame 1 to a suitable position so that the fixing holes 2 on the frame 1 correspond to the pre-embedded connectors in the concrete. Subsequently, the staff rotates the sleeve 6 and rotates the screw 7. Since the screw 7 is internally threaded with the sleeve 6, the screw 7 will rotate and extend out of the sleeve 6. In this way, the overall length of the screw 7 and the sleeve 6 increases until the pressure plate 8 abuts against the ground. Under the action of the connecting ball 10, the pressure plate 8 can rotate, and then stably fit with the ground. At this time, a triangular structure is formed among the frame 1, the sleeve 6 and the screw 7 as a whole, and the ground, so as to achieve the purpose of supporting the frame 1. Since support components are provided on both sides of the frame 1, the installation accuracy of the frame 1 is improved. Secondly, the length of the screw 7 can be adjusted according to the space at the construction site. When the extended length of the screw 7 is larger, the inclination angle of the sleeve 6 is larger, so that the sleeve 6 and the screw 7 support the frame 1 more stably. Further, the extended lengths of all the screws 7 can be kept the same. Since the concrete ground is a flat ground during construction, the forces exerted by the screw 7 and the sleeve 6 to support the frame 1 can be the same, so that the stability of the frame 1 can be improved. Under the action of the sleeve 6 and the screw 7, during the construction process of installing the frame 1 and splicing multiple frames 1, the staff does not need to manually support the frame 1, reducing the labor intensity, and the supporting forces received on both sides of the frame 1 can be consistent, which improves the stability and accuracy of the support;

[0030] Further, when the installation and splicing of multiple frames 1 are all completed, at this time, the frame 1 does not need to be supported. The staff rotates the screw 7 in the reverse direction so that the screw 7 retracts into the sleeve 6. Subsequently, the sleeve 6 is rotated so that the sleeve 6 can be kept in a vertical state, and the sleeve 6 can be inserted into the slot 11. The pressure plate 8 can be located inside the placement groove 12. The connector is used to pass through the first jack 13 and the second jack 14, so that the pressure plate 8, the inner bottom surface of the frame 1 and the ground are fixed together, realizing the storage of the sleeve 6. The sleeve 6 can increase the bearing capacity of the frame 1, and at the same time increase the connectivity between the device and the ground, ensuring the stability of the assembled light steel building structure.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
