Description

Technical Field

[0001] This utility model relates to the field of prefabricated building construction technology, and in particular to a prefabricated building construction device that is easy to assemble and disassemble. Background Technology

[0002] In the construction industry, especially for various projects in the construction phase, temporary prefabricated houses play a crucial role. They provide temporary accommodation for construction workers, set up on-site offices for project managers and supervisors, and also serve as temporary storage locations for building materials and equipment. They are an important guarantee for the smooth progress of the entire construction project. These temporary prefabricated houses are ubiquitous on construction sites and are the cornerstone supporting the normal operation of construction projects.

[0003] Publication number CN213682507U discloses a lightweight steel panel house for easy assembly and disassembly in the field of lightweight steel house technology. The key technical points of the solution include a base, the top of which is fixedly connected with two sets of tenon and mortise structures, each set having two tenon and mortise structures. Side plates are provided on opposite sides of the two sets of tenon and mortise structures, and back plates are provided on opposite sides of both sets of tenon and mortise structures. The back plates and side plates are engaged with the tenon and mortise structures. A top plate is engaged with the top of the tenon and mortise structures. Two fasteners are fixedly connected to the top two sides of the base and the bottom two sides of the top plate.

[0004] When the connecting plate is inserted into the connecting groove on the inner wall of the tenon column, the side plate and the rear plate can be installed on the tenon column for tenon connection through the matching groove of the connecting plate. The fixing grooves at the four corners of the bottom of the top plate that match the locking blocks serve to fix the position of the top plate. However, the disadvantage of this device is that its disassembly and assembly capabilities are poor, which makes it inconvenient to install and disassemble the prefabricated house as needed in actual use. The operation is not convenient and significantly increases labor and time costs.

[0005] Therefore, those skilled in the art have provided a prefabricated building structure that is easy to assemble and disassemble, in order to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a prefabricated building structure that is easy to assemble and disassemble. This prefabricated building structure features components such as front panels, rear panels, and side panels that slide into the frame. With the help of rotating blocks, limiting blocks, and positioning pins, it ensures that the components can be quickly and stably assembled. Furthermore, during disassembly, it can be quickly disassembled simply by pulling out the positioning pins, which greatly saves labor and time costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A prefabricated building structure for easy assembly and disassembly includes a base plate, two side plates, a front plate, a rear plate, a top plate, a single-headed positioning pin, a first double-headed positioning pin, and a second double-headed positioning pin. The base plate has four fixedly connected frame edges at its upper corners. Two limiting blocks are fixedly connected to the upper end of one side face of each of the multiple frame edges. A sliding cylinder is fixedly connected to the lower end of one side face of each of the multiple frame edges. Limiting rods are slidably connected inside each of the multiple sliding cylinders. Springs are sleeved on the outside of each of the multiple limiting rods. Rotating blocks are rotatably connected to the upper end of both sides of the front and rear plates. A first limiting plate is fixedly connected to the upper end of both the front and rear plates. L-shaped rotating plates are rotatably connected to the lower ends of one side face of each of the two side plates. A second limiting plate is fixedly connected to the upper end of each of the two side plates. Multiple sliding grooves are formed on the outer side of the upper end of the top plate.

[0009] Through the above technical solution, the prefabricated house is designed with components such as front panels, rear panels, and side panels that slide into the frame. With the help of rotating blocks, limiting blocks, and positioning pins, the components can be quickly and stably assembled. At the same time, disassembly can be performed quickly by simply pulling out the positioning pins, which greatly saves labor and time costs.

[0010] Furthermore, both ends of the multiple rotating blocks are tightly fitted with the limiting blocks, and multiple single-headed positioning pins penetrate the rotating blocks and the limiting blocks and have a first pin inserted through one end.

[0011] Through the above technical solution, the tightly fitting end faces ensure the uniform transmission of force, while the through single-headed positioning pin and the first pin form a double locking mechanism, effectively preventing the rotating block from shifting or rotating after being subjected to force, thus ensuring the sturdiness of the prefabricated house structure.

[0012] Furthermore, both first limiting plates and both second limiting plates pass through the top plate via sliding grooves, and multiple first double-headed positioning pins are provided between the two second limiting plates, and multiple second double-headed positioning pins are provided between the two first limiting plates. Both ends of the multiple first double-headed positioning pins and the multiple second double-headed positioning pins are provided with second pins.

[0013] Through the above technical solution, the double-headed positioning pins penetrate multiple limiting plates and are locked with a second pin, forming a stable frame structure, which greatly enhances the stability and deformation resistance of the top plate and ensures the safety and reliability of the prefabricated house roof structure.

[0014] Furthermore, one end face of each of the multiple L-shaped rotating plates is in contact with the lower surface of the sliding cylinder, and the multiple limiting rods extend through the L-shaped rotating plates to the lower end of the L-shaped rotating plates.

[0015] Through the above technical solution, the tight fit between the L-shaped rotating plate and the sliding cylinder, and the through fixation of the limiting rod, enhance the connection stability between the side plate and the frame. The limiting rod extends to the lower end of the L-shaped rotating plate, further restricting its rotation and displacement, and ensuring the stability of the side plate when subjected to external forces.

[0016] Furthermore, a second positioning plate is fixedly connected to the lower end of each of the two side plates, and a first positioning plate is fixedly connected to the lower end of each of the front and rear plates. The two first positioning plates and the two second positioning plates are all located inside the positioning groove.

[0017] By using the above technical solution, and by setting a positioning plate at the lower end and placing it inside the positioning groove, the horizontal displacement of the front panel, rear panel, and side panel is further restricted, making each panel more stable in the vertical direction, enhancing the support and anti-overturning ability of the bottom of the prefabricated house, and improving the overall structural stability.

[0018] Furthermore, the lower surfaces of the plurality of second double-headed locating pins are all in contact with the upper surface of the top plate, and the lower surfaces of the plurality of first double-headed locating pins are all in contact with the upper surfaces of the plurality of second double-headed locating pins.

[0019] Through the above technical solution, the top plate, the first limiting plate and the second limiting plate form an integral structure through this tight connection, which enhances the connection strength between the top and the sides of the prefabricated house and improves the rigidity and stability of the overall structure.

[0020] Furthermore, connecting strips are fixedly connected to both ends of the two side plates, and connecting grooves are opened on both sides of one end of the front plate and the rear plate, with multiple connecting strips located inside the connecting grooves.

[0021] Through the above technical solution, the connecting strip is embedded inside the connecting groove to form a tight connection structure, which restricts the relative displacement between the panels, improves the connection strength at the corners of the prefabricated house, and enhances the overall torsional resistance and deformation resistance of the prefabricated house.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a prefabricated building structure that is easy to assemble and disassemble. When in use, the front and rear panels slide into the frame, causing the rotating block to rotate and fit against the limiting block, and are fixed by a single-headed positioning pin. The side panels slide in simultaneously, the L-shaped rotating plate rotates and fits against the sliding cylinder, and the spring pushes the limiting rod to limit the position. The top panel cooperates with the limiting plate through the sliding groove, and is further reinforced by double-headed positioning pins to ensure stable connection of each panel, enhance the stability of the prefabricated building, prevent loosening and falling off during use, provide a more solid and reliable space, and reduce safety hazards. When disassembling, simply pull out the positioning pin to quickly separate each panel, which greatly saves disassembly time and labor costs. Attached Figure Description

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1-5The present invention provides a specific embodiment of a prefabricated building structure that is easy to assemble and disassemble, comprising a base plate 1, two side plates 15, a front plate 8, a rear plate 9, a top plate 22, a single-headed positioning pin 12, a first double-headed positioning pin 19, and a second double-headed positioning pin 20. Frames 2 are fixedly connected to the four corners of the upper end of the base plate 1. Two limiting blocks 3 are fixedly connected to the upper end of one side face of the multiple frame plates 2. Sliding cylinders 4 are fixedly connected to the lower end of one side face of the multiple frame plates 2. Limiting rods 6 are slidably connected inside the multiple sliding cylinders 4. Springs 5 ​​are sleeved on the outside of the multiple limiting rods 6. Rotating blocks 11 are rotatably connected to the upper end of both sides of the front plate 8 and the rear plate 9. A first limiting plate 10 is fixedly connected to the upper end of both the front plate 8 and the rear plate 9. L-shaped rotating plates 17 are rotatably connected to the lower end of one side face of the two side plates 15. A second limiting plate 16 is fixedly connected to the upper end of the two side plates 15. Multiple sliding grooves 23 are opened on the outer side of the upper end of the top plate 22.

[0033] The prefabricated house is designed with components such as front panel 8, rear panel 9, and side panel 15 that slide into the frame 2. With the help of rotating block 11, limit block 3, and positioning pins, it ensures that the components can be quickly and stably assembled. At the same time, it can be quickly disassembled by simply pulling out each positioning pin, which greatly saves labor and time costs.

[0034] Both ends of the multiple rotating blocks 11 are tightly fitted with the limiting blocks 3, and multiple single-headed positioning pins 12 penetrate the rotating blocks 11 and the limiting blocks 3, with a first pin 13 penetrating one end. The tightly fitted end faces ensure uniform force transmission, while the penetrating single-headed positioning pins 12 and the first pin 13 form a double locking mechanism, effectively preventing the rotating blocks 11 from shifting or rotating after being subjected to force, ensuring the stability of the prefabricated house structure. The two first limiting plates 10 and the two second limiting plates 16 penetrate the top plate 22 through the sliding grooves 23, and multiple first double-headed positioning pins 19 are penetrating between the two second limiting plates 16, and multiple second double-headed positioning pins 20 are penetrating between the two first limiting plates 10. Both ends of the first positioning pin 19 and multiple second double-headed positioning pins 20 are provided with second pins 21. The double-headed positioning pins pass through multiple limiting plates and are locked with the second pins 21, forming a stable frame structure. This greatly enhances the stability and deformation resistance of the top plate 22, ensuring the safety and reliability of the prefabricated house roof structure. One end face of multiple L-shaped rotating plates 17 is in contact with the lower surface of the sliding cylinder 4, and multiple limiting rods 6 extend through the L-shaped rotating plates 17 to the lower end of the L-shaped rotating plates 17. Through the tight fit between the L-shaped rotating plates 17 and the sliding cylinder 4, and the through fixation of the limiting rods 6, the connection stability between the side plate 15 and the frame 2 is enhanced. The limiting rods 6 extend to the lower end of the L-shaped rotating plates 17, further enhancing the stability of the connection between the side plate 15 and the frame 2. The rotation and displacement of the side plate 15 are restricted, ensuring its stability under external force. The lower ends of both side plates 15 are fixedly connected to second positioning plates 18, and the lower ends of the front plate 8 and rear plate 9 are fixedly connected to first positioning plates 14. Both first positioning plates 14 and two second positioning plates 18 are located inside the positioning groove 7. By setting positioning plates at the lower ends and placing them inside the positioning groove 7, the horizontal displacement of the front plate 8, rear plate 9, and side plate 15 is further restricted, making each plate more stable in the vertical direction, enhancing the support and anti-overturning ability of the prefabricated house bottom, and improving the overall structural stability. The lower surfaces of multiple second double-headed positioning pins 20 are in contact with the upper surface of the top plate 22, and multiple first double-headed positioning pins 19... The lower surfaces of the top plate 22 are all in contact with the upper surfaces of the multiple second double-headed positioning pins 20. The top plate 22, the first limiting plate 10 and the second limiting plate 16 form an integral structure through this tight connection, which enhances the connection strength between the top and the sides of the prefabricated house and improves the rigidity and stability of the overall structure. The two side plates 15 are fixedly connected to the two end faces of each side plate. The front plate 8 and the rear plate 9 are provided with connecting grooves 24 on both sides of one end face. The multiple connecting strips 25 are all inside the connecting grooves 24. The connecting strips 25 are embedded in the connecting grooves 24 to form a tight connection structure, which restricts the relative displacement between the plates, improves the connection strength of the corners of the prefabricated house, and enhances the overall torsional resistance and deformation resistance of the prefabricated house.

[0035] Working principle: During use, the front plate 8 and the rear plate 9 slide into the frame 2, causing the rotating block 11 to slide and rotate, so that the rotating block 11 is tightly fitted with the limiting block 3, and the single-headed positioning pin 12 completes the limiting. At the same time, the side plate 15 slides into the frame 2, and its L-shaped rotating plate 17 rotates and is tightly fitted with the sliding cylinder 4. The spring 5 inside the sliding cylinder 4 pushes the limiting rod 6 to limit it. In addition, the sliding groove 23 at the upper end of the top plate 22 cooperates with the first and second limiting plates 16, and with the limiting effect of the first and second double-headed positioning pins 20, a stable and firm connection between the various plates is ensured. This combination of limiting blocks 3, positioning pins, and springs 5 ​​not only enhances the stability between the various components of the prefabricated house, but also ensures that the prefabricated house structure is not easily loosened or detached during use, thus providing a more robust and reliable temporary space and effectively reducing safety hazards caused by structural instability. During disassembly, simply pulling out each positioning pin allows for quick separation between the various panels, greatly saving disassembly time and labor costs, and achieving quick and convenient assembly and disassembly. This makes the prefabricated house highly practical and economical in construction sites and other situations where frequent relocation and reorganization are required.
