[0002] With the rapid development of industrialized construction, prefabricated buildings have been widely used in residential, temporary and public facilities due to their advantages such as high construction efficiency, good environmental protection and standardized components. As an important form of prefabricated building, prefabricated frame houses are based on the modular assembly of prefabricated components to achieve rapid assembly and flexible disassembly.

[0003] Most frame components, such as wall panels and roof panels, require a large number of special connectors to connect to the main frame. The installation process is complicated, and it requires a lot of manpower for later maintenance or disassembly. It is not easy to reuse. The components are poorly compatible due to welding. A lot of adjustments are required during on-site assembly. It is also difficult to flexibly adjust the floor plan or size of the house according to actual needs, and its adaptability is weak.

[0004] Some prefabricated frames have insufficient joint strength, especially at the connection between columns and wall panels, which are prone to deformation or loosening due to stress concentration, resulting in limited wind and earthquake resistance. At the same time, the frame as a whole lacks effective reinforcement structure, which makes it prone to swaying under load, affecting the safety of use. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 5This utility model provides a technical solution: a prefabricated frame house, including a base frame 1. L-shaped columns 4 are fixedly connected to the four corners of the upper surface of the base frame 1. Connecting columns 7 are provided at the center of opposite inner surfaces of the L-shaped columns 4. The lower ends of the connecting columns 7 are fixedly connected to the surface of the base frame 1. Sliding grooves 22 are provided on both sides of the L-shaped columns 4, and sliding grooves 21 are provided on both sides of the connecting columns 7. One side of the sliding groove 22 is slidably connected to the inner wall of one side of the sliding groove 21. Sliding wall panel 216 and sliding groove 22 are slidably connected to sliding wall panel 10 on the other side. The worker first inserts sliding wall panel 10 vertically along the sliding groove 22 on both sides of the L-shaped column 4, and then pushes sliding wall panel 216 into the sliding groove 21 of the connecting column 7 and the sliding groove 22 of the adjacent L-shaped column 4 at the same time. This sliding connection structure does not require on-site cutting or grinding, and even non-professional workers can quickly get started, meeting the urgent need for "rapid installation". It can also be disassembled and transferred to other construction sites for reuse later.

[0024] Reference Figure 4 , Figure 5 X-shaped reinforcing rods 20 are provided on the outer surface of the sliding wall panel 216. There are two sets of X-shaped reinforcing rods 20 in both the vertical and horizontal directions. Four screws 23 are threadedly connected to the surface of the X-shaped reinforcing rods 20. The four screws 23 are evenly distributed at the four corners of the X-shaped reinforcing rods 20. The other end of the screws 23 passes through the L-shaped column 4 and the connecting column 7 respectively and is threaded with nuts 24. The construction workers first attach the two sets of vertical X-shaped reinforcing rods 20 to the surface of the sliding wall panel 216, aligning their four corners with the reserved holes of the L-shaped column 4 and the connecting column 7. Then, the screws 23 are passed through the holes and the nuts 24 are screwed on for initial fixation. Subsequently, two more sets of X-shaped reinforcing rods 20 are added in the horizontal direction. By tightening all the nuts 24, a "horizontal and vertical interwoven" reinforcement system is formed to ensure structural safety under extreme weather conditions.

[0025] Reference Figure 2 The top surface of the L-shaped column 4 is provided with an upper top plate 12. The lower end of the upper top plate 12 is fixedly connected to the inner wall of the upper end of the sliding groove 1 21 and the sliding groove 2 22. The outer sides of both ends of the upper top plate 12 are provided with L-shaped connecting plates 2. The outer ends of the L-shaped connecting plates 2 are threadedly connected with fixing columns 13. The worker aligns the connecting rod 19 at the lower end of the upper top plate 12 with the sliding groove 1 21 and the sliding groove 2 22 of the L-shaped column 4 and the connecting column 7, and slowly lowers it so that the connecting rod 19 is completely embedded in the groove. Then, the L-shaped connecting plates 2 are installed on the outer sides of both ends of the top plate so that they fit against the outer wall of the column. The fixing column 13 is screwed into the threaded hole of the connecting plate and the column. When disassembling later, only the fixing column 13 needs to be screwed out in the opposite direction to hoist the top plate, which is convenient for building modification or relocation.

[0026] Reference Figure 3Four connecting seats 17 are fixedly connected to the upper surface of the top plate 12. The four connecting seats 17 are evenly distributed at the four corners of the top plate 12. Support rods 18 are fixedly connected to the inner walls of the connecting seats 17. Inclined plates 3 extending to the outer sides of both ends of the upper surface of the connecting seats 17 are fixedly connected to both ends of the top plate 12. A cylindrical connecting rod 19 is fixedly connected to the upper end of the inclined plate 3. The support is stable by the even force of the four connecting seats 17. The inclined plate 3 extends along the outer sides of both ends of the top plate 12 and forms an angle with the horizontal plane, which not only avoids rainwater from remaining on the plate surface, but also guides the rainwater to the drainage ditches on both sides through the water grooves opened on the surface.

[0027] Reference Figure 2 The inner walls of the base frame 1 are fixedly connected to several U-shaped blocks 14 on opposite sides. These U-shaped blocks 14 are evenly distributed laterally. The inner walls of the U-shaped blocks 14 are fixedly connected to bottom crossbeams 15. The lower surfaces of the base frame 1 are fixedly connected to both ends of the base 5. The lower end of the base 5 is provided with a fixing seat 6. The upper surface of the fixing seat 6 is provided with fixing holes 8. The base 5 is slidably connected to the inner wall of the fixing holes 8. The surface of the inclined plate 3 is provided with a water trough. The lower end of the surface of the sliding wall panel 10 is rotatably connected to a connecting door 9. The upper end of the connecting door 9 is provided with a viewing window. The upper surface of the sliding wall panel 10 is fixedly connected to a window 11. The lower end of the base 5 is provided with a fixing seat 6. The surface of the fixing seat 6 is provided with fixing holes 8 that match the base 5. After the base 5 is slidably connected to the inner wall of the fixing holes 8, the house becomes more stable. The lower end of the surface of the sliding wall panel 10 is provided with a connecting door 9. The upper end of the connecting door 9 is provided with a viewing window for easy observation of the outside situation. The upper surface of the sliding wall panel 10 is fixedly connected to a window 11 to ensure indoor ventilation and lighting.

[0028] The working principle and usage process of this utility model: A symmetrical support structure is formed by the L-shaped columns 4 at the four corners of the base frame 1 and the connecting column 7 at the center of the opposite side. The sliding groove 22 of the L-shaped column 4 and the sliding groove 21 of the connecting column 7 constitute a "slot-rail" installation channel. The sliding wall panel 10 is independently inserted along the sliding groove 22 of the L-shaped column 4, while the sliding wall panel 16 is simultaneously embedded in the sliding groove 21 of the connecting column 7 and the sliding groove 22 of the adjacent L-shaped column 4, forming a "crisscrossing" wall enclosure. This ensures both rapid positioning of the wall panel and lateral constraint of the wall panel through the groove walls. To limit its horizontal displacement and lay the foundation for subsequent reinforcement, the X-shaped reinforcing rods 20 on the outer side of the sliding wall panel 16 are reinforced through a "two-way cross" layout: the vertical X-shaped reinforcing rods 20 bear the vertical load of the building (such as self-weight and pressure from the superstructure), while the horizontal X-shaped reinforcing rods 20 resist horizontal forces (such as wind load and seismic shear force). After the screw 23 passes through the L-shaped column 4, the connecting column 7 and the X-shaped reinforcing rod 20, the preload generated by tightening the nut 24 can also prevent the wall panel from shaking. The top plate 12 is embedded in the sliding groove 1 21 and the sliding groove 2 2 through the connecting rod 19 at the lower end. The top slot of plate 22 achieves initial connection with the column. The L-shaped connecting plate 2 fits against the outer corner of the L-shaped column 4. The fixing posts 13 at both ends penetrate the connecting plate and are screwed into the pre-threaded holes of the column, forming a "corner reinforcement" to transfer the vertical load of the top plate 12 to the column. At the same time, the close contact between the connecting rod 19 and the trough wall restricts the horizontal swaying of the top plate 12, ensuring the coordinated force bearing of the top structure and the main frame. The connecting seat 17 of the top plate 12 enhances its own deformation resistance through the support rod 18. The inclination angle of the inclined plate 3 guides rainwater to flow into the trough using gravity. The trough flows along the edge of the inclined plate 3. The slope directs rainwater to both sides of the house, preventing water accumulation and leakage at the top. The U-shaped blocks 14 of the bottom frame 1 provide "support and lateral restraint" to the bottom beam 15, enhancing the overall integrity of the bottom structure. The sliding fit between the base 5 and the fixed seat 6 allows for height adjustment based on the flatness of the foundation. The connecting door 9 integrated into the sliding wall panel 10 is connected to the wall panel via hinges, enabling opening and closing for passage. The viewing window and window 11 are sealed with sealing strips to fit the edge of the wall panel, ensuring both lighting and ventilation. The bolt connection between the window frame and the wall panel enhances the overall integrity and prevents localized weakening of the wall panel's strength due to door and window installation.
