Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a supporting device for the construction of inner walls of assembled buildings. Background Art

[0002] Prefabricated building interior walls refer to a construction process that uses on-site installation. They are characterized by being prefabricated, assembled, and decorated in the factory and then directly transported to the construction site for installation. This can greatly save time and engineering costs. In order to ensure the safety and stability of the structure, support devices are required to temporarily support the interior walls during the construction process.

[0003] In the prior art, a Chinese patent document with publication number CN116575742A proposes a support device for the construction of an inner wall of an assembled building, comprising two groups of support components for supporting a wall, the support component comprising a first support member and a second support member, the first support member and the second support member both comprising a support top seat, a support diagonal rod and a support base arranged in sequence from top to bottom, the support diagonal rod comprising a top rod, a first adjustment ring, a transition rod, a second adjustment ring and a bottom rod arranged from top to bottom, the lower part of the top rod, the inside of the first adjustment ring, the upper and lower parts of the transition rod, the inside of the second adjustment ring and the upper part of the bottom rod are all provided with threads, the lower part of the top rod and the upper part of the transition rod are both located inside the first adjustment ring and matched with its threads, the lower part of the transition rod and the upper part of the bottom rod are both located inside the second adjustment ring and matched with its threads, through the design of a three-stage support diagonal rod, the range of adjustment of the support diagonal rod can be made more suitable for a variety of construction conditions, but this scheme still has the following shortcomings when actually used: During the construction of the interior walls of prefabricated buildings, the wall surfaces are usually divided and constructed piece by piece. Therefore, each wall surface needs to be individually provided with a supporting device, and two sets of supporting devices are usually used to support the same wall surface, and the support is provided near the edge of the wall surface.

During the rotation of the bevel gear 307, the transmission rod 306 is used to drive the docking assembly to operate, which will drive the lifting assembly to operate, thereby achieving the effect of driving the sliding rods 2 on both sides to rise and fall at the same time, making it convenient to adjust the supporting strength of the supporting devices on both sides at the same time to ensure the balance of the support.

[0025] like Figure 2 , Figure 3 and Figure 5As shown, the docking assembly includes a first cylinder 401 rotatably connected to the end of the hollow box 301, an end of the first cylinder 401 away from the hollow box 301 is movably interspersed with a second cylinder 402, an end of the second cylinder 402 extending into the first cylinder 401 is fixedly connected to a round tooth plate 403, a tooth groove 404 is provided inside the first cylinder 401, the round tooth plate 403 is limitedly slid inside the tooth groove 404, a coil spring 405 is provided inside the tooth groove 404, one end of the coil spring 405 abuts against the inner wall of the tooth groove 404, and the other end abuts against the outer surface of the round tooth plate 403, a docking groove 406 is provided at the end of the second cylinder 402, and a docking block 407 is provided inside the docking groove 406; The second cylinder 402 is pushed toward the inside of the first cylinder 401, so that the circular tooth plate 403 slides inside the tooth groove 404 and squeezes the coil spring 405.

After the first cylinder 401 is released, the coil spring 405 rebounds and pushes the first cylinder 401 to be mounted on the outer surface of the docking block 407, completing the docking of the docking assembly with the two pillars 1, so that the two pillars 1 are connected, which facilitates the linkage of the two pillars 1.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, a lifting assembly is arranged in the bottom cavity of the pillar 1, a dispersion assembly is arranged at the end of the slide rod 2, and a base 8 is hingedly connected to the bottom end of the pillar 1; The lifting assembly includes a worm 501 movably inserted into the lower part of the outer surface of the pillar 1, a shaft 502 is rotatably connected to the lower inner wall of the pillar 1, a worm wheel 503 is fixedly sleeved in the middle of the outer surface of the shaft 502, the worm wheel 503 is meshed with the worm 501, a driving wheel 504 is fixedly sleeved on the side of the outer surface of the shaft 502, a threaded rod 505 is movably arranged inside the pillar 1, the threaded rod 505 is threadedly connected to the inside of the slide rod 2, a driven wheel 506 is fixedly connected to the bottom end of the threaded rod 505, the driven wheel 506 is meshed with the driving wheel 504, a strip groove 507 is opened through the outer surface of the pillar 1, a slider 508 is fixedly connected to the outer surface of the slide rod 2, the slider 508 slides inside the strip groove 507, the end of the transmission rod 306 away from the bevel gear 307 is fixedly connected to the first cylinder 401, and the end of the worm 501 extending out of the pillar 1 is fixedly connected to the docking block 407; When the rocker 308 is rotated and the docking assembly is driven to operate, the worm 501 will be driven to rotate, and the worm 501 will rotate and drive the worm wheel 503 to rotate synchronously. During the rotation of the worm wheel 503, the driving wheel 504 is driven to rotate through the shaft 502, and then the driven wheel 506 is driven to rotate synchronously, and the driven wheel 506 drives the threaded rod 505 to rotate. Since the sliders 508 at both ends of the slide bar 2 slide in the strip groove 507, the threaded rod 505 will drive the slide bar 2 to rise and fall along the pillar 1 during rotation, thereby achieving the purpose of driving the slide bar 2 to rise and fall and realizing the effect of adjusting the supporting strength.

[0027] like Figure 6 and Figure 7 As shown, the switching assembly includes a hoop 601 rotatably connected to the middle of the outer surface of the sleeve 303, an extension rod 602 is fixedly connected to the side of the hoop 601, and one end of the extension rod 602 extending out of the hollow box 301 is movably sleeved with a sleeve 603, and a limiting groove 605 is provided through the outer surface of the hollow box 301, and the extension rod 602 is slidably connected to the inside of the limiting groove 605, and pin rods 604 are fixedly connected to both sides of the sleeve 603, and a pin groove 606 is provided on the outer surface of the hollow box 301, and the pin groove 606 is distributed in three groups from top to bottom, and the pin rod 604 is slidably clamped in the inside of the pin groove 606; Pull the circular sleeve 603 outward to make the pin rod 604 slide out of the pin groove 606, then push the extension rod 602 to slide along the limit groove 605, and then drive the sleeve 303 to slide along the combination rod 302 through the circular hoop 601, and after moving to the appropriate position, push the circular sleeve 603 to make the pin rod 604 snap into the corresponding pin groove 606. By setting three groups of different pin grooves 606, the pin rod 604 can be snapped in different positions, thereby achieving the switching of the bevel gear 307 and the meshing of different gears. When the bevel gear 307 is in mesh with the full gear, When the wheel 304 is engaged, rotating the rocker 308 can drive the bevel gears 307 on both sides to rotate simultaneously through the full gear 304, thereby achieving the effect of simultaneously adjusting the lifting and lowering of the slide bar 2. When the bevel gear 307 is engaged with the half gear 305, rotating the rocker 308 half gear 305 will only drive the bevel gear 307 on one side to rotate, thereby achieving the effect of adjusting the lifting and lowering of the single-sided slide bar 2, which is convenient for adjusting the supporting strength of the corresponding supporting device according to the supporting degree of the adjacent inner walls, ensuring that the adjacent inner walls on both sides are on the same horizontal plane, avoiding misalignment.

[0028] like Figure 8 and Fig. 9As shown, the dispersion assembly includes a round seat 701 hinged at the end of the slide rod 2 away from the pillar 1, a push rod 703 is hinged on the side of the round seat 701, a round block 704 is hinged on the end of the push rod 703 away from the round seat 701, a pressure plate 702 is arranged on the outer surface of the round block 704, a cylinder 705 is fixedly connected to the middle of the round seat 701, a disc spring 706 is sleeved on the outer surface of the cylinder 705, the cylinder 705 is inserted in the middle of the pressure plate 702, and the disc spring 706 abuts against the outer surface of the pressure plate 702; The support of the slide bar 2 on the inner wall will be pressed on the inner wall through the pressure plate 702. The slide bar 2 is supported on the round seat 701. When the slide bar 2 pushes the round seat 701 to move toward the pressure plate 702, the round seat 701 will press the four corners of the pressure plate 702 through the push rod 703. At the same time, the middle part will squeeze the butterfly spring to press the middle part of the pressure plate 702, thereby dispersing the supporting force of the slide bar 2 to multiple positions of the pressure plate 702, ensuring the uniformity of the pressure force of the pressure plate 702 on the inner wall and improving the supporting effect.

[0029] The technical solution provided by the present invention is that during the construction process of the inner wall of the prefabricated building, a supporting device is used to support the inner wall. First, the base 8 is locked on the floor, and then the support rod and the sliding rod 2 are tilted so that the dispersed assembly is pressed against the surface of the inner wall. The hollow box 301 is installed between the two pillars 1 using the docking assembly, and the second cylinder 402 is pushed into the interior of the first cylinder 401 so that the round tooth plate 403 slides inside the tooth groove 404 and squeezes the coil spring 405. Then, the docking groove 406 at the end of the first cylinder 401 is aligned with the docking block 407. After the first cylinder 401 is released, the coil spring 405 rebounds and pushes the first cylinder 401 to be sleeved on the outer surface of the docking block 407, completing the docking of the docking assembly with the two pillars 1, so that the two pillars 1 are connected, which facilitates the linkage of the two pillars 1, and then the rocker 308 is rotated to drive the combination rod 302 to rotate. The rotation process of the combination rod 302 The sleeve 303 drives the full gear 304 or the half gear 305 to rotate, which in turn drives the bevel gear 307 to rotate synchronously. The transmission rod 306 drives the first cylinder 401 to rotate, which in turn drives the lifting assembly to operate, thereby achieving the effect of driving the slide bars 2 on both sides to rise and fall simultaneously, which is convenient for simultaneously adjusting the supporting strength of the supporting devices on both sides to ensure the balance of the support. The adjusting assembly drives the worm 501 to rotate and drives the worm wheel 503 to rotate synchronously. During the rotation of the worm wheel 503, the driving wheel 504 is driven to rotate through the shaft 502, which in turn drives the driven wheel 506 to rotate synchronously. The driven wheel 506 drives the threaded rod 505 to rotate. Since the sliders 508 at both ends of the slide bar 2 are limited to slide in the strip groove 507, the threaded rod 505 will drive the slide bar 2 to rise and fall along the pillar 1 during its rotation, thereby achieving the purpose of driving the slide bar 2 to rise and fall, and realizing the effect of adjusting the supporting strength. When the supporting forces of the two supporting components are different, the circular sleeve 603 is pulled outward to make the pin rod 604 slide out of the pin groove 606, and then the extension rod 602 is pushed to slide along the limit groove 605, and then the sleeve 303 is driven to slide along the combination rod 302 through the circular hoop 601. After moving to the appropriate position, the circular sleeve 603 is pushed to make the pin rod 604 snap into the corresponding pin groove 606. The three groups of different pin grooves 606 are provided to make the pin rod 604 snap into different positions, thereby achieving the switching of the bevel gear 307 and the different gear meshing conditions. When the bevel gear 307 is meshed with the full gear 304, the rotating rocker 308 can drive the bevel gears 307 on both sides to rotate simultaneously through the full gear 304, thereby achieving the effect of simultaneously adjusting the lifting and lowering of the slide rod 2. When the bevel gear 307 is meshed with the half gear 305 When the sliding rod 2 is in the state of being lifted up, the half gear 305 of the rocker arm 308 will only drive the bevel gear 307 on one side to rotate, thereby achieving the effect of adjusting the lifting and lowering of the single-sided sliding rod 2, which is convenient for adjusting the supporting strength of the corresponding supporting device according to the supporting degree of the adjacent inner walls, ensuring that the adjacent inner walls on both sides are on the same horizontal plane and avoiding misalignment. In addition, the support of the sliding rod 2 to the inner wall will be pressed on the inner wall through the pressure plate 702, and the sliding rod 2 is supported on the round seat 701. When the sliding rod 2 pushes the round seat 701 to move toward the pressure plate 702, the round seat 701 will press the four corners of the pressure plate 702 through the push rod 703, and at the same time, the middle part will squeeze the butterfly spring to press the middle part of the pressure plate 702, thereby dispersing the supporting force of the sliding rod 2 to multiple positions of the pressure plate 702, ensuring the uniformity of the pressure force of the pressure plate 702 on the inner wall, and improving the stability of the support.
