Description

Technical Field

[0001] This invention relates to the field of prefabricated building installation technology, specifically to a prefabricated building bottom wall support device. 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, and balconies, are prefabricated in factories and then transported to the construction site for assembly and installation using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures.

[0003] When installing prefabricated buildings, assembly is generally done from the bottom up. However, when building the bottom wall components, they need to be spliced ​​with the surrounding walls to form mutual support and maintain stability. The initial wall components are independent before being supported by other components, making them difficult to maintain stability and prone to collapse. Therefore, a prefabricated building bottom wall support device is needed to form triangular supports on the sides of the wall components, ensuring that the individual wall components do not tip over and preventing them from easily collapsing and being damaged.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This prefabricated building's bottom wall support device, through its main board, base plate, mounting port, guide mechanism, triangular support mechanism, engagement positioning mechanism, engagement unlocking mechanism, snap-fit ​​mechanism, fixing mechanism, anti-slip mechanism, and unit association mechanism, can form triangular support on the side of the wall components through the triangular support mechanism, and form a stable one-way lock through the engagement positioning mechanism. At the same time, the fixing mechanism and anti-slip mechanism form a stable grip between the device and the ground, ensuring that each independent wall component will not tip over and preventing the wall components from easily collapsing and being damaged.

[0017] 2. The prefabricated building's bottom wall support device, through the setting of guide frame, guide slide, anti-slip slide, connecting slider, limiting slider and connecting column, can form a linear guide for the connecting end block and ensure the correlation between the triangular support mechanism, the engagement positioning mechanism and the engagement unlocking mechanism.

[0018] 3. The prefabricated building's bottom wall support device, through the installation of a bonding frame, support arm, connecting end block, and first anti-slip pad, ensures that the included angle between the bonding frame and the support arm can be adjusted as the connecting end block slides on the guide frame surface. This ensures that the device can provide support for wall components on ground with different slopes, and also ensures that the support arm can provide support for wall components with different inclinations.

[0019] 4. The prefabricated building's bottom wall support device, through the setting of a one-way rack, limiting blocks, spring forks, one-way meshing teeth, and synchronous meshing teeth, can form a one-way sliding limit on the connecting end block through the meshing between the two limiting blocks and the one-way rack. This ensures that the support arm can form effective support on one side when the bonding frame is adjusted to any angle, and prevents the bonding frame from easily loosening.

[0020] 5. The prefabricated building's bottom wall support device, through the setting of rocker, pull plate, reset spring, pull pin, triangular hole, limit guide plate, guide hole and sliding pin, ensures that when the fitting frame is released from support, the one-way locking can be released by rocker. At the same time, the setting of triangular hole ensures that when the connecting slider slides inward and the limit block is pressed, it can freely tilt inward and avoid the pull pin forming an obstruction.

[0021] 6. The prefabricated building's bottom wall support device, through the setting of positioning plates, locking blocks, positioning blocks, connecting shafts, rotating blocks, baffles, and positioning holes, enables the locking blocks to form a locking limit on the connecting plates, and the baffles to block the locking blocks to form a locking position, thereby achieving a stable connection between the connecting plates and the main plate.

[0022] 7. The prefabricated building's bottom wall support device, through the setting of a bearing seat, waist ring, connecting frame, stop pin, compression spring and positioning cone, can improve the device's grip on the ground by inserting the positioning cone into the ground during installation, and prevent the device from slipping easily. At the same time, when the positioning cone is not in use on cement or other impervious ground surfaces, the bearing seat can be turned outward to prevent the positioning cone from damaging the ground.

[0023] 8. The prefabricated building's bottom wall support device, through the setting of a storage frame, toothed plate, flip plate, snap-fit ​​sliding hole, pin shaft, snap ball, buckle groove, sand discharge hole and second anti-slip pad, so that when the device forms support on a smooth ground, the second anti-slip pad can increase friction and increase resistance, and when the second anti-slip pad is not in use, it can be stored inside by flipping the flip plate.

[0024] 9. The prefabricated building's bottom wall support device, through the setting of connecting plates, reinforced ridges, connecting waist holes and protruding columns, allows multiple device units to be spliced ​​into a whole using the connecting plates, ensuring the correlation between multiple units, ensuring the resistance complementarity between different units, and improving the anti-interference of independent units.

[0049] Working principle: Multiple devices are placed on both sides of the wall fitting. The bonding frame 501 is rotated to make it fit against the wall. When the bonding frame 501 rotates, it pulls the connecting end block 503 inward through the support arm 502. At this time, the connecting slider 404 slides synchronously inside the guide frame 401. When the connecting slider 404 slides, the limiting block 602 is continuously compressed and retracted along the one-way rack 601 and then continuously squeezed and reset by the spring fork 603 until the bonding frame 501 reaches the designated position. Then, the limiting block 602 is blocked and locked by the one-way rack 601. At this time, if the device is on soil, the connecting frame 903 can be flipped so that the positioning cone 906 passes through the waist ring 902 and inserts into the ground to form a stable fixation. If the device is on cement or smooth ground, the flip plate 1003 can be pried out and flipped so that the flip plate 100... 3. Flip the plate along the pin 1005, then slide the flip plate 1003 near the pin 1005 end to the other end of the snap-fit ​​hole 1004, and use the snap-fit ​​bead 1006 to snap the flip plate 1003 into the snap-fit ​​hole 1004, so that the second anti-slip pad 1009 flips out. The friction of the second anti-slip pad 1009 forms the resistance of the support. Then, a connecting plate 1101 is set between each pair of adjacent main plates 1, so that the connecting waist hole 1103 is inserted into the protrusion 1104, and the snap-fit ​​of the connecting plate 1101 is formed by the snap-fit ​​block 802. Then, rotate the rotating block 805 so that the positioning block 803 is snapped into the positioning hole 807. At this time, the baffle 806 abuts against the snap-fit ​​block 802 to lock the connecting plate 1101. The connecting plate 1101 connects each main plate 1 into a whole, and the bonding frame 501 forms a stable support.
