Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated houses, and particularly relates to an energy-saving and environment-friendly prefabricated house. Background Art

[0002] A prefabricated building refers to transferring a large amount of on-site operation work in the traditional construction method to the factory. In the factory, precast components such as floor slabs, wall panels, stairs, and balconies required for the building are all processed and manufactured. Subsequently, these precast components are transported to the building construction site and assembled and installed on-site through reliable connection methods to form a complete building. Prefabricated buildings cover various types such as precast concrete structures, steel structures, and modern timber structures. They adopt standardized design, factory production, assembly construction, information management, and intelligent applications, and are representatives of modern industrial production methods.

[0003] With the development of modern industrial technology, houses can be manufactured in batches and sets like machine production. As long as the prefabricated house components are transported to the construction site and then assembled on-site. Due to its advantages of fast construction speed and low production cost, prefabricated buildings have been rapidly and widely promoted globally. Especially in the scenarios of field construction or houses that need to be temporarily built, prefabricated buildings show their unique advantages with their reusable characteristics.

[0004] However, there are still some problems in the existing temporary houses during the process of multiple reuse. Conventional assembled houses require a large number of spare parts during assembly, and the installation process is relatively cumbersome, which greatly affects the overall construction speed and the efficiency is low. In addition, during the transportation process, these houses need to be disassembled. The process of loading and unloading the components is time-consuming and laborious, and when arriving at the next usage location, they need to be reassembled again. The whole process is very cumbersome, not only consuming a large amount of precious time, but also increasing the costs of manpower and material resources.

[0005] Therefore, we propose an energy-saving and environment-friendly prefabricated house to solve the above technical problems. Summary of the Invention

The lower ends of the second fixing pieces are connected to the lower frame.

[0009] In a further technical solution, through holes in the vertical direction are provided on both sides of the flipping wall panel. Upper fixing holes and lower fixing holes corresponding to the positions of the through holes are respectively provided on the upper frame and the lower frame. The fixing screws sequentially pass through the upper fixing holes, the through holes and the lower fixing holes to connect the upper frame, the flipping wall panel and the lower frame.

[0010] In a further technical solution, the upper fixing holes on both sides of the upper frame are arranged staggeredly, and receiving grooves are opened on the top surfaces of the upper fixing holes on both sides of the upper frame. The receiving grooves are parallel to the upper frame and extend towards the opposite side. The fixing screws can be received and placed in the receiving grooves. An anti-loss component connected to the fixing screws is provided in the receiving grooves.

[0011] In a further technical solution, the anti-loss component includes a connecting rod. The connecting rod is vertically installed in the receiving groove and above the upper fixing hole. A connecting groove is opened on the side surface of the fixing screw. The connecting rod is arranged in the connecting groove, and a locking component for locking the position of the fixing screw is provided on the side of the receiving groove away from the upper fixing hole.

[0012] In a further technical solution, the locking assembly includes a U-shaped block, a locking screw, and a locking block. The U-shaped block is disposed on a side of the storage groove away from the upper fixing hole and has an upward opening. The locking screw passes through the opening of the U-shaped block and is connected to the fixing screw.

[0016] In a further technical solution, a support beam is provided below the bottom plate at the middle of the lower frame, and the slide rail is connected to the support beam.

[0017] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: 1.

At the same time, the process of loading and unloading the vehicle is more simple and fast. During installation, only simple unfolding and basic fixing operations are required, without the need to use a large number of spare parts, saving installation time and effectively reducing the costs of labor and materials.

[0018] 2. After being unfolded, the present invention connects the upper frame, the flipping wall panel, and the lower frame by passing the fixing screw through the upper fixing hole, the through hole, and the lower fixing hole in sequence, thereby effectively enhancing the overall stability and wind resistance of the house, improving the durability and safety of the house, and the installation process is more concise and efficient. In addition, the use of connecting parts is reduced, effectively saving installation time and reducing the working intensity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Referring to Figures 1-9 , the present invention provides an energy-saving and environment-friendly prefabricated house, which includes a base frame 1, a lower frame 2, an upper frame 3, a floor 4, a top plate 5 and wall panels. The long sides of the lower frame 2 are all connected above the base frame 1 through a plurality of support columns 6. The floor 4 is detachably installed inside the lower frame 2. The top plate 5 is detachably installed inside the upper frame 3. The wall panels include inner folding wall panels 7 symmetrically arranged on the long sides of the lower frame 2 and flipping wall panels 8 symmetrically arranged on the short sides of the lower frame 2. The inner folding wall panel 7 includes an upper folding wall panel 701 and a lower folding wall panel 702. The outer sides of the upper folding wall panel 701 and the lower folding wall panel 702 are rotatably connected through a hinge 9. The upper part of the upper folding wall panel 701 is rotatably connected to the upper frame 3. The lower part of the lower folding wall panel 702 is rotatably connected to the lower frame 2. Fixed screw rods 10 are arranged on both sides of the short sides of the upper frame 3. The fixed screw rods 10 sequentially penetrate through the upper frame 3, the flipping wall panel 8 and the lower frame 2, and nuts 11 are threadedly sleeved at both ends of the fixed screw rods 10. A slider hinge assembly is arranged at the bottom of the flipping wall panel 8. A slide rail 12 is arranged below the bottom plate of the lower frame 2. The slider hinge assembly is installed on the slide rail 12 and can drive the flipping wall panel 8 to slide and be received in the gap between the base frame 1 and the lower frame 2.

[0025] Through modular design, this prefabricated house aims to shorten the construction period, improve construction efficiency, reduce labor intensity, while reducing energy consumption and environmental pollution, and realizing reusable, which fully embodies the concepts of energy conservation, environmental protection and sustainable development. Its specific working principle is as follows: After the precast components are fabricated and completed in the factory, they enter the assembly stage. First, the base frame 1, which is the part in contact with the ground, is placed at the bottom. Then, the long sides of the lower frame 2 are welded above the base frame 1 through multiple support columns 6 to form the basic support structure of the house. Subsequently, the slide rail 12 is welded to the lower frame 2, and the slider hinge assembly is installed on the slide rail 12. After that, the flipping wall panel 8 is pushed into the gap between the base frame 1 and the lower frame 2 to achieve the storage of the flipping wall panel 8. Next, the floor 4 is installed inside the lower frame 2 to ensure that the ground is flat and stable, while the top plate 5 is installed inside the upper frame 3 to provide a complete top cover for the house. For the folding wall panel 7, the upper folding wall panel 701 and the lower folding wall panel 702 are first connected together by a hinge 9 to ensure flexible rotation. Then, the lower part of the lower folding wall panel 702 is rotatably connected to the lower frame 2, and the upper part of the upper folding wall panel 701 is rotatably connected to the upper frame 3 to ensure the rotational connection between the upper frame 3 and the lower frame 2 and the folding wall panel 7. Finally, by folding the upper folding wall panel 701 and the lower folding wall panel 702 inward, and at the same time the height of the upper frame 3 is also reduced synchronously, the volume of the house is reduced, which is convenient for transportation and storage. In the scenarios of field construction or houses that need to be temporarily erected, by transporting the prefabricated house to the destination, only by unfolding and fixing it can meet the daily use, effectively saving the assembly time. Specifically, the unfolding process is simple and efficient; first, use the hoisting equipment to slowly lift the upper frame 3. As the height of the upper frame 3 rises, the folding wall panels 7 on both sides also start to rotate and unfold. When the upper frame 3 reaches the highest height, the folding wall panels 7 are also fully unfolded in place. Then, the flipping wall panel 8 is pulled out from the gap between the base frame 1 and the lower frame 2 until the slider hinge assembly is dragged to the outermost position. Then, the flipping wall panel 8 is rotated and erected, and stably maintained at the short side position of the lower frame 2, forming the enclosure structure of the house together with the folding wall panels 7. Finally, the fixing screw 10 passes through the upper frame 3, the flipping wall panel 8 and the lower frame 2 in sequence, and is fixed by using the nut 11, thus completing the construction work of the house. Compared with the traditional prefabricated house, this prefabricated house is assembled after being manufactured, has a small volume after folding and storage, is convenient for transportation, and effectively reduces the transportation cost. At the same time, the loading and unloading process is more simple and fast. During installation, only simple unfolding and basic fixing operations are required, without the use of a large number of spare parts, which not only saves the installation time, but also effectively reduces the costs of manpower and material resources.

[0026] In a specific embodiment, refer to Figures 1-5, on the upper parts of both sides of the upper folding wall panel 701, first rotating shafts 13 are respectively provided. A first fixing piece 14 is movably sleeved on each first rotating shaft 13. The upper end of the first fixing piece 14 is connected to the upper frame 3. On the lower parts of both sides of the lower folding wall panel 702, second rotating shafts 15 are respectively provided. A second fixing piece 16 is movably sleeved on each second rotating shaft 15. The lower end of the second fixing piece 16 is connected to the lower frame 2.

[0027] Through the rotational cooperation of the first rotating shaft 13 and the first fixing piece 14, and the rotational cooperation of the second rotating shaft 15 and the second fixing piece 16, the rotatable connection between the upper folding wall panel 701 and the upper frame 3, and the rotatable connection between the lower folding wall panel 702 and the lower frame 2 are respectively realized, ensuring that the upper folding wall panel 701 and the lower folding wall panel 702 can respectively rotate flexibly relative to the upper frame 3 and the lower frame 2, so as to facilitate the folding and unfolding of the house structure. Specifically, the first fixing piece 14 is sleeved on the first rotating shaft 13, and its upper end is fixedly welded to the upper frame 3 by welding. Similarly, the second fixing piece 16 is sleeved on the second rotating shaft 15, and its lower end is fixedly welded to the lower frame 2 by welding. This connection method is not only stable and reliable, but also easy to implement, making the folding and unfolding processes of the house structure very smooth and beneficial to use.

[0028] In a specific embodiment, refer to Figure 8 , on both sides of the flipping wall panel 8, vertical through holes 17 are respectively provided. On the upper frame 3 and the lower frame 2, upper fixing holes 18 and lower fixing holes 19 corresponding to the positions of the through holes 17 are respectively provided. The fixing screw 10 sequentially passes through the upper fixing hole 18, the through hole 17 and the lower fixing hole 19 to connect the upper frame 3, the flipping wall panel 8 and the lower frame 2.

[0029] Vertical through holes 17 are opened on both sides of the flipping wall panel 8, aligned with the upper fixing holes 18 of the upper frame 3 and the lower fixing holes 19 of the lower frame 2, and fixed by tightening nuts 11 after the fixing screw 10 passes through, thereby connecting the upper frame 3, the flipping wall panel 8 and the lower frame 2 together, effectively enhancing the overall stability and wind resistance of the house, and improving the durability and safety of the house. This fixing method makes the installation process more concise and efficient, and reduces the use of connecting parts, effectively saving the installation time and reducing the working intensity.

[0030] In a specific embodiment, refer to Figure 1 , Figure 2 and Figure 3, the upper fixing holes 18 on both sides of the upper frame 3 are arranged staggeredly, and receiving grooves 20 are formed on the top surfaces of the upper fixing holes 18 on both sides of the upper frame 3. The receiving grooves 20 are parallel to the upper frame 3 and extend towards the opposite side. The fixing screw 10 can be received and placed in the receiving groove 20, and a component for preventing loss connected to the fixing screw 10 is provided in the receiving groove 20.

[0031] By staggeredly arranging the upper fixing holes 18 on both sides of the upper frame 3 and forming the receiving grooves 20, the fixing screw 10 can be received in the receiving groove 20 when not in use. With the component for preventing loss, it can effectively prevent the fixing screw 10 from being lost during transportation, storage or installation, ensuring the integrity of the accessories.

[0032] In a specific embodiment, refer to Figure 5 and Figure 8 , the component for preventing loss includes a connecting rod 21. The connecting rod 21 is vertically installed in the receiving groove 20 and is located above the upper fixing hole 18. A connecting groove 22 is formed on the side surface of the fixing screw 10. The connecting rod 21 is arranged in the connecting groove 22, and a locking component for locking the position of the fixing screw 10 is provided on the side of the receiving groove 20 away from the upper fixing hole 18.

[0033] Through the cooperative design of the connecting rod 21 and the connecting groove 22 of the component for preventing loss, it can prevent the connecting rod 21 from sliding out of the connecting groove 22, thereby effectively avoiding the loss of the fixing screw 10 during storage or transportation. When building a house, only need to rotate the fixing screw 10, align the lower end of the fixing screw 10 with the upper fixing hole 18, and lower the fixing screw 10 to pass through the upper fixing hole 18, the through hole 17 and the lower fixing hole 19 in sequence, thereby completing the connection of the upper frame 3, the flipping wall panel 8 and the lower frame 2. The setting of the locking component provides an additional safety guarantee. After the fixing screw 10 is received in the receiving groove 20, the locking component can effectively lock the fixing screw 10 in the receiving groove 20, ensuring that even if there is bumping or vibration during transportation, the fixing screw 10 will not accidentally slide out, ensuring its safety and stability in the non-use state.

[0034] In a specific embodiment, refer to Figure 3 and Figure 6 , the locking component includes a U-shaped block 23, a locking screw 24 and a locking block 25. The U-shaped block 23 is arranged on the side of the receiving groove 20 away from the upper fixing hole 18, and the opening faces upwards. The locking screw 24 passes through the opening of the U-shaped block 23 and is connected to the fixing screw 10. The locking block 25 is threadedly sleeved on the side of the locking screw 24 away from the fixing screw 10.

[0035] After the fixing screw 10 is placed in the storage groove 20, the locking screw 24 at its end is caught in the opening of the U-shaped block 23. By turning the locking block 25, the locking block 25 is fitted to the side of the U-shaped block 23 away from the fixing screw 10. At this time, the connecting rod 21 on the other side is located at the end of the connecting groove 22, thus effectively tightening and completing the locking, thereby enhancing the stability of the fixing screw 10 in the storage groove 20 and preventing it from accidentally slipping out during transportation or storage.

[0036] In a specific embodiment, referring to Figure 9 , it further includes a pitched roof 26. Installation holes matching the locking screws 24 are provided around the pitched roof 26, and the pitched roof 26 is provided with slopes that incline downward to both sides.

[0037] After the house is built, by removing the locking block 25 from the locking screw 24, aligning the installation holes around the pitched roof 26 with the four locking screws 24 respectively, and screwing in the locking block 25 after passing through, the pitched roof 26 is covered on the top surface of the house structure. It can not only accelerate rainwater drainage and reduce the risk of water accumulation, but also shield the top surface of the house structure, reduce direct sunlight, play a certain role in cooling, improve the living comfort, and at the same time reduce the potential damage to the top surface of the house structure caused by wind and rain attacks and hail impacts, reducing the maintenance cost. It is worth mentioning that the pitched roof 26 can also be made into a foldable type, so as to reduce the volume and facilitate transportation.

[0038] In a specific embodiment, referring to Figure 4 and Figure 7 , the slider hinge assembly includes a sliding end 27, a fixed end 28 and a hinge end 29. The sliding end 27 is installed on the slide rail 12, the fixed end 28 is connected to the bottom of the flipping wall panel 8, and both ends of the hinge end 29 are hinged to the sliding end 27 and the fixed end 28 respectively. A card slot 30 is provided on the outer side of the lower frame 2, and the fixed end 28 is tightly clamped in the card slot 30.

[0039] Through the cooperation of the sliding end 27, the fixed end 28 and the hinge end 29, the slider hinge assembly realizes an efficient and stable motion mechanism. The sliding end 27 is installed on the slide rail 12, providing a stable sliding track foundation for the whole assembly; the fixed end 28 is connected to the flipping wall panel 8, ensuring a firm connection between the flipping wall panel 8 and the slider hinge assembly; and both ends of the hinge end 29 are hinged to the sliding end 27 and the fixed end 28 respectively, enabling the sliding end 27 and the fixed end 28 to rotate flexibly around the hinge end 29. This design enables the flipping wall panel 8 to be stored or unfolded as needed, greatly improving the space utilization efficiency. In addition, the design of the card slot 30 can tightly clamp the fixed end 28 in the card slot 30, which can not only improve the aesthetics, but also prevent the flipping wall panel 8 from shaking in the left and right directions, further enhancing the stability and safety of the house structure.

[0040] In a specific embodiment, refer to Figure 7 , a plurality of right-angled mounting plates 31 are provided on the inner sides of the upper frame 3 and the lower frame 2, and the floor 4 and the bottom plate are mounted on the right-angled mounting plates 31 and are detachably connected to the right-angled mounting plates 31.

[0041] By providing the right-angled mounting plates 31 on the inner sides of the upper frame 3 and the lower frame 2, and detachably connecting the floor 4 and the top plate 5 to the right-angled mounting plates 31 with bolts, the floor 4 and the top plate 5 can be effectively supported, and the bearing capacity and stability of the structure can be improved.

[0042] In a specific embodiment, refer to Figure 4 , a support beam 32 is provided below the bottom plate in the middle of the lower frame 2, and the slide rail 12 is connected to the support beam 32.

[0043] By providing the support beam 32, the load of the floor 4 can be effectively dispersed, and the compressive capacity of the floor 4 can be improved. In addition, the design of connecting the slide rail 12 to the support beam 32 avoids the slide rail 12 being arranged along the entire long side of the lower frame 2, effectively shortening the length of the slide rail 12. While maintaining the functionality of the slide rail 12, the rigidity of the slide rail 12 is greatly improved. The enhanced rigidity enables the slide rail 12 to maintain extremely high stability during use, and is not easily deformed or displaced, thereby ensuring the reliability and safety of the entire slide rail 12 system.
