Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically a prefabricated building with high safety performance. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Prefabricated buildings have advantages such as fast construction speed, labor saving, and less restriction by weather conditions. However, some existing prefabricated buildings still have defects in terms of structural stability and safety performance. In particular, when facing natural disasters such as earthquakes, their seismic performance and the overall structural deformation resistance need to be strengthened. In addition, the strength of some connection parts is insufficient, which can easily lead to loosening and damage during long-term use or when subjected to external impacts, affecting the service life and safety of the building. Utility Model Content

[0010] As a preferred embodiment, L-shaped fixing brackets are fixedly installed on both sides of the top of the auxiliary cross plate, and second corner braces are fixedly installed on both sides of the inner end of the L-shaped fixing brackets. The outer ends of the second corner braces are welded to the inner side of the L-shaped fixing brackets.

[0011] As a preferred embodiment, the column is provided with evenly distributed longitudinal reinforcing ribs, the upper and lower ends of which are welded and fixed to the bottom of the top plate and the top of the connecting plate, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up damping springs and dampers, can play a good role in buffering and shock absorption when the building is subjected to vibration, thereby improving the seismic performance of the building and reducing the damage of vibration to the building structure. The setting of the diagonal bracing plate can support and reinforce the connecting plate, enhance the stability of the connection between the connecting plate and the support frame, and prevent the connecting plate from tilting or deforming under stress. The first corner bracing plate can strengthen the connection strength between the top plate and the support frame, improve the stability of the top plate installation, and prevent the top plate from loosening or falling off under stress.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0019] Please see Figure 1 As shown, this utility model provides a prefabricated building with high safety performance, including a base 1, a support frame 2 welded to the top of the base 1, damping springs 3 welded to both sides of the bottom of the inner cavity of the support frame 2, a damper 4 sleeved inside the damping spring 3, a connecting plate 6 jointly installed on the upper end of the damper 4 and the damping spring 3, a diagonal brace 5 installed on one side of the bottom of the connecting plate 6 by reinforcing bolts, the lower end of the diagonal brace 5 connected to the bottom of the inner cavity of the support frame 2, a column 8 fixedly installed on the top of the connecting plate 6, a top plate 10 fixedly installed on the upper end of the column 8 extending to the outside of the support frame 2, auxiliary horizontal plates 11 horizontally installed on both sides of the top of the top plate 10, and the bottom of the top plate 10 connected to the outside of the support frame 2 by a first corner brace 14.

[0020] This technical solution, by setting up damping springs 3 and dampers 4, can play a good role in buffering and reducing vibration when the building is subjected to vibration, thereby improving the seismic performance of the building and reducing the damage of vibration to the building structure. The setting of the diagonal bracing plate 5 can support and reinforce the connecting plate 6, enhance the stability of the connection between the connecting plate 6 and the support frame 2, and prevent the connecting plate 6 from tilting or deforming under stress. The first corner bracing plate 14 can strengthen the connection strength between the top plate 10 and the support frame 2, improve the installation stability of the top plate 10, and prevent the top plate 10 from loosening or falling off under stress. The overall structural design is reasonable, and the connections between the components are firm, which can effectively improve the overall structural stability and safety performance of the building and extend the service life of the building. Example

[0021] Based on Embodiment 1, this utility model is as follows: Figure 2 As shown, a reinforcing crossbeam 7 is fixedly installed on the inner end of the top of the connecting plate 6, and the reinforcing crossbeam 7 is symmetrically arranged between the tops of the two connecting plates 6; a reinforcing support plate 9 is installed in the middle of both sides of the support frame 2 by reinforcing bolts, and the lower end of the reinforcing support plate 9 is designed to be inclined and connected to the top of the base 1 by high-strength bolts.

[0022] Adopting such Figure 1 The technical solution shown features a reinforced crossbeam 7 symmetrically positioned on the top of the two connecting plates 6, which integrates the dispersed forces, enhances the overall lateral integrity of the structure, and allows the connecting plates 6 and columns 8 on both sides to work together to bear the load, avoiding unilateral overload. The reinforced support plate 9 is inclined to connect the support frame 2 and the base 1. With the help of the triangular stabilizing structure, it can efficiently transmit and disperse the lateral forces on the support frame 2, improving the overall anti-tipping ability. Together, they enhance the stability and load-bearing balance of the building structure.

[0023] Secondly, in the technical solution, limit frames 12 are bolted to the outer ends of the top plate 10. The inner end of the limit frame 12 is bent and is locked to the outside of the side of the auxiliary horizontal plate 11. A rectangular limit frame 15 is welded to the center of the top of the top plate 10. The inner end of the auxiliary horizontal plate 11 is horizontally inserted into the interior of the rectangular limit frame 15. A vertical plate 16 is welded to the center of the top of the rectangular limit frame 15. Top support plates 17 are bolted to both sides of the upper end of the vertical plate 16. The surface of the top support plate 17 has a slot horizontally opened.

[0024] Its adoption is as follows Figure 1The technical solution shown has a limiting frame 12 at both ends of the top plate 10 installed with bolts. Its inner end is bent and clipped to the outside of the side of the auxiliary horizontal plate 11, which can firmly limit the auxiliary horizontal plate 11 from the side, preventing the auxiliary horizontal plate 11 from shifting or shaking when under force, and ensuring the stability of the connection between the auxiliary horizontal plate 11 and the top plate 10. The rectangular limiting frame 15 at the top center of the top plate 10 allows the inner end of the auxiliary horizontal plate 11 to be inserted into it from the side, forming an effective fixation for the auxiliary horizontal plate 11 from the inside. In cooperation with the limiting frames 12 at both ends, the auxiliary horizontal plate 11 is firmly constrained as a whole, which greatly improves the installation firmness of the auxiliary horizontal plate 11, thereby enhancing the load-bearing stability of the top plate 10. Example

[0025] This utility model is as follows Figures 1-5 As shown, L-shaped fixing brackets 13 are fixedly installed on both sides of the top of the auxiliary horizontal plate 11. Second corner bracing plates 18 are fixedly installed on both sides of the inner end of the L-shaped fixing brackets 13. The outer end of the second corner bracing plates 18 is welded to the inner side of the L-shaped fixing brackets 13. The interior of the column 8 is evenly distributed with longitudinal reinforcing ribs. The upper and lower ends of the longitudinal reinforcing ribs are welded and fixed to the bottom of the top plate 10 and the top of the connecting plate 6, respectively. The auxiliary horizontal plate 11 is a hollow rectangular steel structure. Reinforcing ribs are arranged horizontally at intervals inside. The two sides of the reinforcing ribs are welded to the inner wall of the auxiliary horizontal plate 11, and sealing plates are welded to both ends of the auxiliary horizontal plate 11.

[0026] By adopting the above technical solution, the L-shaped fixing brackets 13 on both sides of the top of the auxiliary horizontal plate 11 can reinforce the connection between the auxiliary horizontal plate 11 and the top plate 10 in the longitudinal direction, thereby enhancing the overall integrity of the two. The second corner support plate 18 on its inner side is welded to the L-shaped fixing bracket 13, and the triangular stable structure further enhances the structural strength and load-bearing capacity of the L-shaped fixing bracket 13 itself, effectively preventing the L-shaped fixing bracket 13 from deforming due to excessive force, and ensuring stable support for the auxiliary horizontal plate 11. The evenly distributed longitudinal stiffeners inside column 8 greatly enhance the bending and compressive strength of column 8, making column 8 more stable during load transfer, better able to withstand the pressure transmitted from top plate 10, reducing the risk of column 8 being damaged due to excessive force, and providing reliable vertical support for the upper structure. The auxiliary horizontal plate 11 adopts a hollow rectangular steel structure, which reduces its own weight. The reinforcing ribs arranged horizontally inside are welded to the inner wall, which significantly improves the lateral bending resistance and overall structural strength of the auxiliary horizontal plate 11. The sealing plates welded at both ends prevent impurities from entering the interior and affecting the structural performance.

[0027] The working principle of this utility model is as follows: When a building is subjected to horizontal or vertical vibrations such as earthquakes, the damping spring 3 will first absorb part of the vibration energy through its own elastic deformation. At the same time, the damper 4 will consume the kinetic energy generated by the vibration by utilizing its damping characteristics. The two work together to greatly reduce the vibration intensity transmitted to the connecting plate 6 and the upper structure, playing a role in buffering and shock absorption. Under the support of the damping spring 3 and the damper 4, the connecting plate 6 is connected to the bottom of the inner cavity of the support frame 2 through the bottom inclined brace 5. The inclined brace 5 distributes the vertical and lateral forces on the connecting plate 6 to the support frame 2 at an inclined angle, preventing the connecting plate 6 from deforming due to excessive force at a single point. On the other hand, the column 8 at the top of the connecting plate 6 transmits the load upward to the top plate 10. The longitudinal reinforcing ribs inside the column 8 enhance its own bending resistance and ensure the stable transmission of force. The top plate 10 serves as the upper load-bearing structure. Its top auxiliary horizontal plate 11 expands the load-bearing area by extending laterally, reducing the pressure per unit area. The inner end of the auxiliary horizontal plate 11 is inserted into the rectangular limiting frame 15, and the outer end is fixed by the limiting frame 12. With the reinforcement of the L-shaped fixing frame 13 and the second corner support plate 18, a stable lateral support system is formed, which effectively resists the lateral thrust on the top plate 10.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
