Description

Technical Field

[0001] This utility model relates to the field of building ceiling technology, and in particular to a prefabricated building ceiling. Background Technology

[0002] With the acceleration of urbanization and the popularization of green building concepts, prefabricated buildings have become an important development direction in the modern construction field due to their advantages such as short construction cycle, high resource utilization rate, and low environmental pollution. As a core component of building envelope, prefabricated roofs need to meet diverse functional requirements, such as wind and earthquake resistance of industrial plants, rapid disassembly and assembly of temporary buildings, and photovoltaic integration in green buildings. Traditional cast-in-place roofs suffer from problems such as low construction efficiency, serious material waste, and difficult maintenance. Prefabricated roofs, through the combination of factory prefabrication and on-site assembly, effectively solve the above pain points. However, there is still room for improvement in terms of transportation convenience, environmental adaptability, and intelligent operation and maintenance.

[0003] Most of the current mainstream prefabricated canopies adopt a modular design, with aluminum alloy frames or steel trusses as the supporting structure, combined with covering materials such as PVC tarpaulin, color steel plates or glass. Their mechanical structure mainly relies on bolt connections or welding processes to fix the components. Some products improve installation efficiency through quick connection methods such as magnetic attraction and buckles. These technical principles focus on structural stability and basic function realization, but they do not give enough consideration to dynamic environmental adaptability, transportation space compression ratio and intelligent maintenance.

[0004] However, the existing prefabricated ceiling installation process has prominent problems such as insufficient positioning accuracy, low installation efficiency and high labor costs. Traditional installation methods rely on manual measurement and bolt pre-tightening, requiring multiple adjustments to the hole alignment, and the positioning error generally exceeds ±3mm, leading to subsequent sealing failure or structural stress concentration. In addition, the installation of complex curved ceilings requires professional technicians to calibrate using laser theodolites. Therefore, a prefabricated building ceiling is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a prefabricated building roof, which aims to improve the problems of insufficient positioning accuracy, low installation efficiency and high labor costs in the existing prefabricated roof installation process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated building roof includes a roof and a support beam. Both the roof and the support beam are internally threaded with multiple fixing screws. Multiple auxiliary assembly components are provided at the bottom of the roof to facilitate the assembly of the roof by users.

[0008] The auxiliary assembly component includes a connecting block, which is fixedly connected to the bottom of the ceiling. An arched block is fixedly connected to the bottom of the connecting block, and multiple fixed shafts are fixedly connected to the bottom of the arched block. Fixed plates are fixedly connected to the outer walls of the multiple fixed shafts. Multiple support blocks are fixedly connected to the outer walls of the support beam. Multiple fixed sleeves are fixedly connected inside the multiple support blocks. Limiting plates are fixedly connected inside the fixed sleeves. The limiting plates fit with the fixed plates. The fixed shafts fit with the fixed sleeves. Multiple elastic connecting components are provided at the bottom of the support beam. The elastic connecting components are used to provide elastic support for the ceiling.

[0009] As a further description of the above technical solution:

[0010] The elastic connection assembly includes a connecting plate and a fixing plate. The connecting plate is fixedly connected to the bottom of the support beam, and the fixing plate is fixedly connected to the bottom of the connecting plate.

[0011] As a further description of the above technical solution:

[0012] The side wall of the fixed plate is rotatably connected to multiple sliding shafts, and the outer walls of the multiple sliding shafts are slidably connected to connecting shafts.

[0013] As a further description of the above technical solution:

[0014] One end of each connecting shaft is rotatably connected to a second connecting plate, and the bottom of the second connecting plate is provided with multiple springs.

[0015] As a further description of the above technical solution:

[0016] One end of the spring is fixedly connected to the bottom of the connecting plate 2, and the other end is fixedly connected to the bottom of the fixing plate.

[0017] As a further description of the above technical solution:

[0018] The bottom of the connecting plate 2 is fixedly connected to a sliding column 1, and the outer wall of the sliding column 1 is slidably connected to a sliding column 2.

[0019] As a further description of the above technical solution:

[0020] The bottom of the sliding column 2 is fixedly connected to a support pad, which is made of rubber.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by fitting the bow-shaped block and the support block together, the fixed shaft is inserted into the fixed sleeve. The ceiling is limited by the cooperation of the fixed plate and the limiting plate, thereby achieving the effect of quickly assisting the operator in positioning. This solves the problems of large positioning error, long time for hole alignment and high labor cost in the traditional installation method, and significantly improves the ceiling assembly efficiency.

[0023] 2. In this utility model, the connecting plate and the fixed plate compress the spring to make it elastically deform, which further causes the sliding shaft to slide inside the connecting shaft, and further drives the sliding column one to slide inside the sliding column two, thereby achieving the effect of elastic support for the roof. This solves the problem of easy cracking and stress concentration of traditional rigid support structures under uneven settlement or dynamic loads, and improves the roof's earthquake and wind resistance and long-term stability.

Detailed Implementation

[0030] 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.

[0031] Reference Figure 1 - Figure 3The present invention provides an embodiment of a prefabricated building roof, comprising a roof 1 and a support beam 2. Both the roof 1 and the support beam 2 are internally threaded with multiple fixing screws 3 for firmly fixing the roof 1 to the top of the support beam 2. The bottom of the roof 1 is provided with multiple auxiliary assembly components for facilitating the assembly of the roof 1 by users.

[0032] The auxiliary assembly components include a connecting block 4, which is fixedly connected to the bottom of the ceiling 1 to provide stable connection and support, ensuring the stability of the auxiliary components. An arched block 5 is fixedly connected to the bottom of the connecting block 4, and multiple fixed shafts 6 are fixedly connected to the bottom of the arched block 5. Through the cooperation of the fixed shafts 6 and the fixed sleeves 8, the ceiling 1 can be initially positioned, facilitating assembly by operators. Fixed plates 9 are fixedly connected to the outer walls of the multiple fixed shafts 6. Multiple support blocks 7 are fixedly connected to the outer wall of the support beam 2, and multiple fixed sleeves 8 are fixedly connected inside the multiple support blocks 7 to provide an accurate sliding path for the fixed shafts 6, ensuring the stability of the auxiliary components. Limiting plates 10 are fixedly connected inside the fixed sleeves 8, and the limiting plates 10 and fixed plates 9 engage. Through the cooperation of the limiting plates 10 and fixed plates 9, the ceiling 1 can be accurately positioned, preventing offset during installation. The fixed shafts 6 and fixed sleeves 8 engage. Multiple elastic connecting components are provided at the bottom of the support beam 2 to provide elastic support for the ceiling 1.

[0033] Specifically, in prefabricated ceiling installation environments requiring rapid installation, complex curved surface positioning, high-precision docking, or high-altitude operations, where auxiliary splicing components are needed to improve positioning accuracy, shorten construction time, and reduce labor costs and safety risks, operators first align the bow-shaped block 5 with the support block 7, allowing the bow-shaped block 5 to be engaged into the internal structure of the support block 7 by the weight of the ceiling 1. This process not only ensures a tight fit between the two but also serves as a pre-positioning mechanism. As the bow-shaped block 5 is installed, the fixing shaft 6 begins to slide into the fixing sleeve 8. At this point, the operator applies appropriate squeezing force to cause the fixing piece 9 to undergo plastic deformation, ensuring that the fixing piece 9 can precisely engage with the limiting piece 10. The limiting piece 10 ensures the precise position of the fixing piece 9 after deformation, allowing the ceiling 1 to be quickly and firmly positioned onto the support beam 2, avoiding the loosening or misalignment problems common in traditional installation methods. This process achieves rapid positioning of the ceiling 1, enabling operators to efficiently and accurately complete the splicing work of the ceiling 1, reducing installation time and improving the reliability and stability of the installation.

[0034] Reference Figure 4The elastic connection assembly includes a connecting plate 11 and a fixing plate 12. The connecting plate 11 is fixedly connected to the bottom of the support beam 2, providing stable connection and support for the elastic connection assembly. The fixing plate 12 is fixedly connected to the bottom of the connecting plate 11. Multiple sliding shafts 13 are rotatably connected to the side wall of the fixing plate 12 to distribute the impact force. Water flow ensures that the fixing plate 12 can be pressed downwards. Connecting shafts 14 are slidably connected to the outer walls of the multiple sliding shafts 13. One end of each connecting shaft 14 is rotatably connected to a connecting plate 15. Multiple springs 16 are provided at the bottom of the connecting plate 15 to provide elastic restoring force. To absorb impact and ensure the stability of the canopy 1, one end of the spring 16 is fixedly connected to the bottom of the connecting plate 15 and the other end is fixedly connected to the bottom of the fixing plate 12, thus ensuring that the spring 16 can be compressed and deformed, and ensuring the stability of the deformation of the spring 16. A sliding column 17 is fixedly connected to the bottom of the connecting plate 15, and a sliding column 18 is slidably connected to the outer wall of the sliding column 17. The sliding column 18 is used to further ensure the absorption of impact and the stability of the component movement, and provides a stable movement trajectory for the sliding column 17. A support pad 19 is fixedly connected to the bottom of the sliding column 18. The support pad 19 is made of rubber.

[0035] Specifically, when the foundation experiences uneven settlement, needs to withstand dynamic loads such as wind vibration and earthquakes, or when the roof 1 has a complex curved surface structure, elastic supports are required to avoid stress concentration and cracking risks associated with rigid supports. External forces are transmitted to the fixed plate 12 through the connecting plate 11, causing the fixed plate 12 to apply pressure to the spring 16, resulting in elastic deformation. This process not only provides the necessary elastic support for the roof 1, but also drives the sliding shaft 13 to slide inside the connecting shaft 14 through the deformation of the spring 16, thereby sharing the external forces borne by the roof 1 and ensuring its stability. In addition, the elastic deformation of the spring 16 also causes the sliding column 17 to slide inside the sliding column 18, effectively providing elastic support for the roof 1, preventing the roof 1 from being damaged or deformed due to excessive rigid pressure, and ensuring that it is not affected by external pressure during long-term use, maintaining a stable and good functional state.

[0036] Working principle: When using this prefabricated canopy, the canopy 1 can be fixed to the top of the support beam 2 using fixing screws 3. During assembly, the operator first aligns the bow-shaped block 5 with the support block 7. The weight of the canopy 1 causes the bow-shaped block 5 to engage with the support block 7, thereby allowing the fixing shaft 6 to slide into the fixing sleeve 8. The compressive force causes the fixing piece 9 to deform, thus engaging with the limiting piece 10, achieving the function of quickly positioning the canopy 1. This facilitates quick assembly by the operator. When the canopy 1 is subjected to uneven pressure or strong winds, the connection... The connecting plate 11 transmits force to the fixed plate 12. The compression of the fixed plate 12 causes the spring 16 to undergo elastic deformation. The elastic deformation of the spring 16 provides a certain elastic support force for the ceiling 1. At the same time as the spring 16 deforms, the sliding shaft 13 will slide inside the connecting shaft 14, thereby further distributing the pressure and ensuring the stability of the ceiling 1. At the same time as the spring 16 undergoes elastic deformation, the sliding column 17 will slide inside the sliding column 18, providing elastic support for the ceiling 1 and preventing the ceiling 1 from being damaged or deformed due to excessive rigid pressure.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
