Description

Technical Field

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

[0002] Prefabricated lightweight steel structure houses, as an important carrier of modern industrialized construction, play a crucial role in emergency resettlement, temporary buildings, and modular housing. With the construction industry moving towards green and intelligent development, higher demands are being placed on the seismic performance, thermal insulation, sound insulation, and construction efficiency of these structures. These prefabricated buildings are widely used in disaster area reconstruction, temporary construction sites, and tourism facilities, further highlighting the significant value of optimizing lightweight steel structure house design.

[0003] Existing prefabricated lightweight steel structure houses are prone to thermal bridging in areas with large temperature differences, leading to unstable thermal insulation performance. Ordinary fireproof materials are difficult to form a continuous protective layer on the surface of the steel frame structure, resulting in limited temperature rise control when exposed to fire. The sound insulation structure of the walls has weak ability to block low- and mid-frequency noise. There are still some shortcomings in the hoisting and construction process. Traditional structures lack effective buffer protection mechanisms when placed by cranes, making the steel frame and walls susceptible to damage from instantaneous impact forces. The fixing methods in the current technology are difficult to achieve smooth descent and repositioning during hoisting. Some structural connection nodes may loosen or deform after being subjected to impact. These shortcomings affect construction safety and building quality.

[0004] Therefore, a prefabricated, assembled, lightweight steel structure house is proposed to solve the above problems. Utility Model Content

A buffer mechanism is provided inside the foundation.

[0008] As a further description of the above technical solution:

[0037] Reference Figure 1 - Figure 7 The buffer structure includes a damper 13 and multiple bases 16. The damper 13 is installed inside the foundation 5, and the bases 16 are also installed inside the foundation 5. An elongated groove 21 is formed at the top of each base 16. Multiple fixed posts 17 are slidably connected inside the base 16, and a sliding plate 14 is fixedly connected to the top of each fixed post 17. A sliding post 26 is slidably connected inside the base 16, and its top is fixedly connected to the bottom of the sliding plate 14. A fixed ring 15 is fixedly connected to the outside of each sliding post 26, and two U-shaped blocks 18 are fixedly connected to the outside of each fixed ring 15. A rotating shaft 23 is rotatably connected to the outside of each U-shaped block 18, and the rotating shaft 23 is located away from the U-shaped blocks 18. One end of 18 is rotatably connected to a U-shaped block 22. A slide bar 24 is fixedly connected to the bottom of the U-shaped block 22. A long column 20 is fixedly connected to the outside of the slide bar 24. A spring 19 is sleeved on the outside of the long column 20.

[0039] Working principle: During the assembly of the prefabricated house, a foundation 5 is installed at the bottom, and a fixing plate 12 is installed inside the foundation 5. A steel frame 9 is then installed inside the fixing plate 12 by penetrating the floor 25. Wall surface 3 and wall surface 4 are installed on the outside of the steel frame 9, using a double fixing method. Wall surface 3 interlocks with wall surface 4 via outer clips 27 and is rigidly connected by bolts 6. Rock wool 2 8 and rock wool 1 7 are installed inside wall surface 3 and wall surface 4 as Class A fireproof materials to protect the steel frame 9, delaying the spread of fire and working together with the buffer mechanism to improve the overall building performance. To enhance sound insulation, the steel frame 9 is internally fitted with honeycomb panels 10. The sound insulation cotton 11 inside the honeycomb panels 10 reduces noise. The filling position is tightly integrated with the building envelope, improving the overall sound insulation performance. When the house is lowered by a crane and subjected to impact, the sliding column 26 descends. Under the action of the pivot 23 and spring 19, the base 16 slides, causing the house on top to descend slowly. Its damper 13 absorbs the impact and restores the house to its original position, protecting the steel frame 9 from damage and deformation when subjected to impact, and protecting its internal walls and internal equipment.
