Description

TECHNICAL FIELD

[0002] Prefabricated building refers to a building assembled by prefabricated components at the construction site. In the early stage of field construction, prefabricated buildings are used to quickly build personnel housing and temporary warehouses, providing convenience for the rapid development of engineering construction. Prefabricated buildings are quickly and conveniently disassembled, and their structural components also need to be used multiple times. Most existing prefabricated buildings are buried and fixed during construction, and then the structural components are fixed on the support seat through dowels or screws, and the assembly is completed to form a prefabricated building.

[0003] The support seat structure of common prefabricated buildings is relatively simple and only serves as a fixed support during use. With the increasing demand for use, the support seat has been improved, and some support seats that can prevent earthquakes and winds have gradually appeared on the market, thereby enhancing the structural strength of prefabricated buildings. However, regardless of which support seat, there is a problem during use: the components of the prefabricated building are connected to each other by bolts to form a whole, which is balanced by multiple support seats. In actual use, goods placed in the building cannot be evenly placed, resulting in settlement of the local support seat under pressure. Once the individual support seat settles, stress will occur between the components of the prefabricated building, causing deformation at the connection between the components, making it difficult to disassemble the bolts during disassembly of the prefabricated building, thereby causing difficulties for recycling. In addition, severely deformed components cannot meet the standard for secondary use and can only be scrapped, which increases the construction cost. Therefore, it is necessary to invent a prefabricated building template lifting seat that can effectively compensate for the settlement of the support seat. SUMMARY

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-8 As shown, a prefabricated building formwork lifting seat for construction includes a settlement plate 2, which increases the contact area between the entire device and the ground. A sliding mounting seat 1 is slidably provided in the middle of the settlement plate 2. An anti-loosening platform 3 is fixed to the lower end face of the settlement plate 2. When the entire device is loosened by pressure or tension, the anti-loosening platform 3 slows down the progress of the entire process. A pile bucket assembly 4 is fixedly connected below the anti-loosening platform 3. An end cap 5 is fixed to the bottom of the pile bucket assembly 4. The pile bucket assembly 4 includes a pile wall 44 fixed to the lower end face of the anti-loosening platform 3. The bottom of the wall 44 is provided with a pre-compression elastic mechanism, which is a power storage mechanism. Above the pre-compression elastic mechanism is a rotating component 42 for triggering the pre-compression elastic mechanism. The rotating component 42 is rotatably engaged with the sliding mounting seat 1. When the sliding mounting seat 1 is pressed, it triggers the rotating component 42, causing the rotating component 42 to rotate, thereby driving the pre-compression elastic mechanism to release the stored elastic force. This provides a compensating elastic force to the pressure point, preventing individual lifting seats from settling due to continuous pressure, which would increase the stress of the entire component and cause deformation and damage at the connection.

[0033] As one embodiment of the present invention, such as Figures 2-4As shown: the pre-pressing elastic mechanism is composed of the pile wall 44, the end cover 5 and the lifting assembly 43, the bottom inner wall of the pile wall 44 is fixed with a limiting ring 442, a plurality of sliding grooves are formed in the inner wall of the limiting ring 442, and the lifting assembly 43 and the limiting ring 442 are a matching mechanism, the bottom of the limiting ring 442 cooperates with the lifting assembly 43 to block the upward movement of the lifting assembly 43, and the sliding grooves formed in the limiting ring 442 cooperate with the lifting assembly 43 to move the lifting assembly 43 along the sliding grooves.

[0034] As an embodiment of the present application, as shown in Figure 2 、 Figure 5 and Figure 7 : the lifting assembly 43 includes a sliding sleeve 431 that is in sliding cooperation with the limiting ring 442, the bottom outer wall of the sliding sleeve 431 is provided with a limiting block 436, and the limiting block 436 and the sliding groove of the limiting ring 442 are a matching mechanism, the position of the sliding sleeve 431 and the sliding path of the sliding sleeve 431 are limited by the limiting block 436, the upper end surface of the sliding sleeve 431 is fixed with a jacking base 433, a compression spring 432 is arranged between the lower end surface of the jacking base 433 and the end cover 5, the compression spring 432 is placed between the jacking base 433 and the end cover 5 after being pre-pressed, the end cover 5 and the pile wall 44 are fixed by bolts to limit the downward rebound of the compression spring 432, the limiting block 436 cooperates with the limiting ring 442 to limit the upward ejection of the sliding sleeve 431 under the action of the compression spring 432, thereby forming a pre-pressing elastic mechanism, the central position of the upper end surface of the jacking base 433 is fixed with a jacking support rod 434, a plurality of limiting clamping plates 435 are arranged on the upper end surface of the jacking base 433, and the limiting clamping plates 435 and the rotating assembly 42 are a matching mechanism, the limiting clamping plates 435 enable the rotating assembly 42 to rotate when rotating, drive the lifting assembly 43 to rotate, cause the limiting block 436 to rotate relative to the limiting ring 442, and thereby enable the limiting block 436 to enter the sliding groove to release the elastic force of the compression spring 432, so as to enable the rotating assembly 42 to push the sliding mounting seat 1, and the jacking support rod 434 serves as a support structure and can directly transmit the elastic force released by the compression spring 432 to the abutting position of the rotating assembly 42 and the sliding mounting seat 1.

[0035] As an embodiment of the present application, as shown in Figures 3-4 : the pile wall 44 is provided with a V-shaped sliding groove 441 corresponding to the position of the rolling support shaft 422, the V-shaped sliding groove 441 is divided into a vertical groove and an inclined groove, the inclined groove is used for guiding, when the rotating sleeve 421 moves downward, the rolling support shaft 422 rolls along the inclined groove to cause the rotating assembly 42 to rotate, and the vertical groove is a yielding groove, as the rolling support shaft 422 rolls to the bottom end of the V-shaped sliding groove 441, the lifting assembly 43 is released, and when the lifting assembly 43 moves upward, the rotating assembly 42 can have a larger moving space.

[0036] In practice, after assembling the sliding mounting base 1, settlement plate 2, and anti-loosening platform 3, the pile wall 44 is fixed to the anti-loosening platform 3. Then, the rotating sleeve 421 and rotating connecting plate 424 are installed into the pile wall 44 and tightly attached to the sliding mounting base 1. Then, the rolling support shaft 422 is fixed to the rotating sleeve 421 through the V-shaped groove 441. Next, the second support spring 423 is installed. Then, the sliding sleeve 431, which is fixed with the limit plate 435, lifting base 433, and lifting support rod 434, is fitted into the pile wall 44 along the limit plate 435 and the rotating sleeve 421. Finally, the compression spring 432 is placed in and sealed by the end cap 5, thus forming a complete lifting base. In the initial state, under the action of the second support spring 423, the rotating connecting plate 424 is tightly attached to the sliding mounting base 1, and the rolling support shaft 422 is located at the top of the inclined groove of the V-shaped groove 441. After the lifting base is pre-embedded, the components of the prefabricated building are fixed to the lifting base. On the platform, when the pressure on a certain lifting seat is much greater than that on other lifting seats, the sliding mounting seat 1 is pressed down, thereby gradually compressing the second support spring 423. This causes the sliding mounting seat 1 to push the rotating assembly 42 downward. During this process, the rotating assembly 42 rotates as a whole under the action of the rolling support shaft 422. The limiting plate 435 turns the sliding sleeve 431 to rotate, thereby causing the limiting block 436 at its bottom to move relative to the limiting ring 442. Gradually, the limiting block 436 rotates into the groove opened by the limiting ring 442, thereby releasing the elastic force of the compression spring 432. This causes the compression spring 432 to push the lifting base 433 and the rotating connecting plate 424 upward, pushing the sliding mounting seat 1. This reaction force balances the pressure on the lifting seat at that point, thus ensuring that the entire prefabricated building can maintain uniform stress and prevent further damage. The elastic force of the compression spring 432 used is much greater than that of the second support spring 423.

[0037] As one embodiment of the present invention, such as Figure 5 As shown: The sliding mounting base 1 includes a component mounting platform 11 that slides and fits at the center of the settlement plate 2. A tapered support rod 12 is fixed at the center of the lower end face of the component mounting platform 11. A first support spring 13 is provided on the outer side of the tapered support rod 12. The elastic force of the first support spring 13 is less than that of the second support spring 423. The first support spring 13 plays a role in shock resistance. When the prefabricated building is subjected to external force and causes slight movement, the impact on the building is reduced by the first support spring 13. When the component mounting platform 11 is compressed beyond the preset value, the first support spring 13 is quickly compressed, so that the tapered support rod 12 directly contacts the rotating connecting plate 424, thereby transmitting the pressure to the rotating component 42.

[0038] As one embodiment of the present invention, such as Figure 5As shown: the anti-loose pedestal 3 comprises a conical table 31 fixed at the lower end surface of the settlement plate 2, a plurality of rectangular grooves 311 are circumferentially arranged on the outer wall of the conical table 31, and the anti-loose assembly 32 is matched in the rectangular groove 311. When the individual pressure of the plurality of lifting seats is too large, the other lifting seats will be pulled up, the anti-loose assembly 32 prolongs the time of the whole process when the lifting seat is pressed to cause settlement or pulled to cause loosening, thereby giving the required time when each part of the lifting seat plays a role, and further improving the working stability of the lifting seat.

[0039] As an embodiment of the present application, as shown in Figures 7-8 As shown: the anti-loose assembly 32 comprises a fixed rod 322 fixedly welded in the rectangular groove 311, the fixed rod 322 is rotatably matched with an inverted branch plate 321, the inverted branch plate 321 is a U-shaped open structure, the inverted branch plate 321 is inserted on the fixed rod 322 during installation, one end of the inverted branch plate 321 is provided with a needle 324, the other end of the inverted branch plate 321 is provided with a waist hole penetrating the inverted branch plate 321, the end of the inverted branch plate 321 provided with the waist hole is fixedly welded with a pushing connecting rod 323, and the pushing connecting rod 323 and the rotating assembly 42 are matched mechanisms, the inverted branch plate 321 is rotatably matched around the fixed rod 322 to form a lever structure, when the rotating connecting plate 424 moves upward, the inverted branch plate 321 rotates around the fixed rod 322 by pushing the pushing connecting rod 323, so that the needle 324 reverses outward and inserts into the inner wall of the foundation pit, thereby achieving the purpose of stabilizing the lifting seat.

[0040] As an embodiment of the present application, as shown in Figures 7-8 As shown: the lower end surface of the sliding mounting seat 1 is provided with a limiting pull rod 14 corresponding to the position of the anti-loose assembly 32, and the limiting pull rod 14 is matched with the waist hole of the inverted branch plate 321, and the limiting pull rod 14 is fixed with the component mounting table 11. When the component mounting table 11 is pulled upward, the limiting pull rod 14 pulls the inverted branch plate 321 to deflect, so that the needle 324 penetrates into the inner wall of the foundation pit, thereby preventing the component mounting table 11 from being pulled up.

[0042] As an embodiment of the present application, as shown in Figure 2 The pile wall 44 further comprises a barrel guard 41 fixed outside the pile wall 44, and the barrel guard 41 prevents sundries from entering the pile wall 44 when buried.

After the lifting seat is pre-buried, the components of the fabricated building are fixed on the lifting seat, when the pressure on a lifting seat is much larger than that on other lifting seats, the sliding seat 1 is pressed downward, so that the second supporting spring 423 is gradually compressed, and the sliding seat 1 pushes the rotating assembly 42 to move downward, in this process, the rotating assembly 42 is rotated as a whole under the action of the rolling support shaft 422, the sliding sleeve 431 is rotated by the limiting clamp plate 435, so that the limiting block 436 provided at the bottom thereof is relatively moved with the limiting ring 442, the limiting block 436 is gradually rotated to the sliding groove of the limiting ring 442, so as to release the elastic force of the compression spring 432, the compression spring 432 pushes the lifting base 433 and the rotating connecting plate 424 to move upward, and the sliding seat 1 is pushed, so that the reaction force balances the pressure on the lifting seat, and the entire fabricated building can be kept uniform, avoiding further damage;
