Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, in particular to a steel bar truss floor deck supporting device. Background Art

[0002] With the promotion of green and environmentally friendly building concepts, steel structures are widely used in large public buildings, infrastructure, high-rise residential buildings and other fields due to their high environmental protection and sustainable development. Their design specifications and supporting technologies are becoming increasingly mature and have broad development prospects. Support devices are required to provide auxiliary support during the construction of steel truss floor decks.

[0003] For example, a Chinese patent discloses: an adjustable support device for assembled steel truss floor decking, patent number: CN218467092U. The adjustable support device effectively changes the disadvantages of traditional steel truss floor decking, such as large consumption of temporary frame materials, slow installation and disassembly, and impact on subsequent construction processes. It reduces labor, material and time costs, is reusable and does not affect subsequent construction processes on the same floor. It does not need to be dismantled before subsequent construction, thereby improving construction efficiency.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the above-mentioned device can be removed as a whole for reuse after the supporting operation through an adjustable mechanism, and multiple supporting devices are usually required for construction operations. The above-mentioned supporting devices lack the function of mutual locking. When the devices need to be moved before and after the supporting operation, each device needs to be handled separately, which affects the stability during transportation and takes up more storage space. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a steel truss floor deck support device, which solves the technical problem that the above-mentioned device can be removed as a whole for reuse after the supporting operation through an adjustable mechanism, and that multiple supporting devices are usually required for operation during construction operations. The above-mentioned supporting devices lack the function of mutual clamping. When the devices need to be transported before and after the supporting operation, each device needs to be handled separately, which affects the stability during transportation and takes up more storage space.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A steel bar truss floor bearing plate support device includes two support feet. One end of each of the two support feet is fixedly connected with a round bar. The ends of the two support feet away from the round bar are fixedly connected with connecting plates. A first clamping block is rotatably connected inside each of the two connecting plates. A second clamping block is rotatably connected inside each of the two first clamping blocks. Springs are sleeved on the outer surfaces of the two first clamping blocks and the second clamping blocks. Two groups of springs are respectively sleeved on the outer surfaces of the two connecting plates. A support mechanism is rotatably connected inside each of the two support feet. The support mechanism includes two first support rods, and the two first support rods are respectively rotatably connected inside the two support feet.

[0010] Preferably: A first threaded adjusting rod is slidably connected inside each of the two first support rods. One side of the two support feet close to each other is respectively fixedly connected with a second support rod and a second threaded adjusting rod.

[0011] Preferably: A first adjusting ring is rotatably connected inside the second support rod and the two first support rods.

[0012] Preferably: A connecting seat is rotatably connected inside each of the two first threaded adjusting rods. A threaded rod is slidably connected inside the connecting seat. A second adjusting ring is rotatably connected to the outer surface of the connecting seat.

[0013] Preferably: A rectangular seat is fixedly connected to the upper end of the threaded rod. Two clamping blocks are slidably connected inside the rectangular seat.

[0014] Preferably: A bidirectional screw rod is rotatably connected inside the rectangular seat.

[0015] (III) Beneficial effects

[0016] First, when it is necessary to carry and move the support device, push the round bar connected to one end of a group of support feet into the first clamping block of the other group of support feet. During the sliding process of the round bar, it squeezes the first clamping block and the second clamping block to rotate. When the round bar contacts the inner wall of the first clamping block, the two compressed springs lose the extrusion force. Under the action of the two springs, it drives the first clamping block and the second clamping block to rotate and reset to clamp the round bar. When it is necessary to carry the support feet, connect multiple support feet together, saving the occupied space, which is beneficial to improving the stability during storage in the handling process and achieving the effect of being convenient for handling.

[0017] Second, when clamping and supporting the upper end of the floor bearing plate through the clamping blocks, the bidirectional screw rod can be rotated by screwing. During the rotation of the bidirectional screw rod, it can threadedly drive the two clamping blocks to slide in opposite directions inside the rectangular seat. Before the support operation, the placement distance between the two bidirectional screw rods can be adjusted by screwing the clamping blocks, thereby further improving the flexibility of the device, adapting to different support condition requirements, and being beneficial to improving the adaptability of the device.

Specific implementation manner

[0024] In the embodiment of the present application, by providing a support device for a steel bar truss floor slab, the above-mentioned device can be effectively removed and reused as a whole after the support operation through an adjustable mechanism. During construction operations, multiple support devices are usually required for operation. There is a lack of mutual clamping function between the above-mentioned support devices. When the devices need to be carried before and after the support operation, each device needs to be processed separately, which affects the stability during the carrying process and will occupy a larger storage space. When the support device needs to be carried and moved, the round rod connected to one end of a group of support feet is pushed into the first clamping block of another group of support feet. During the sliding process of the round rod, the first clamping block and the second clamping block are squeezed and rotated. When the round rod contacts the inner wall of the first clamping block, the two compressed springs lose the extrusion force. Under the action of the two springs, the first clamping block and the second clamping block are driven to rotate and reset to clamp the round rod. When the support feet need to be carried, multiple support feet are clamped together, saving the occupied space and being beneficial to improving the stability during storage during the carrying process, achieving the effect of facilitating carrying.

[0025] Embodiment

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the technical problems that the above-mentioned device can be removed and reused as a whole after the support operation through the adjustable mechanism. During the construction operation, multiple support devices are usually required for operation. There is a lack of mutual clamping function between the above-mentioned support devices. When the device needs to be carried before and after the support operation, each device needs to be processed separately, which affects the stability during the handling process and will occupy a larger storage space. The general idea is as follows: A steel bar truss floor slab support device includes two support feet 11. One end of each of the two support feet 11 is fixedly connected to a round rod 12. One end of the two support feet 11 away from the round rod 12 is fixedly connected to a connecting plate 13. A first clamping block 14 is rotatably connected inside each of the two connecting plates 13. A second clamping block 15 is rotatably connected inside each of the two first clamping blocks 14. Springs 16 are sleeved on the outer surfaces of the two first clamping blocks 14 and the second clamping blocks 15. The two groups of springs 16 are respectively sleeved on the outer surfaces of the two connecting plates 13. When it is necessary to carry and move the support device before the device is used or after the support work is completed, place multiple support feet 11 on the same plane, and push the round rod 12 connected to one end of a group of support feet 11 into the first clamping block 14 of the other group of support feet 11. During the sliding process of the round rod 12, it squeezes the first clamping block 14 and the second clamping block 15 to rotate (the first clamping block 14 rotates in the connecting plate 13 through a rotating shaft, and the second clamping block 15 rotates in the first clamping block 14 through a rotating shaft). When the round rod 12 contacts the inner wall of the first clamping block 14, the two compressed springs 16 lose the extrusion force. Under the action of the two springs 16, the first clamping block 14 and the second clamping block 15 are driven to rotate and reset to clamp the round rod 12. When it is necessary to disassemble the two groups of support feet 11 during the next use, the round rod 12 can be manually pulled out of the first clamping block 14 for disassembly. By clamping multiple support feet 11 together when the support feet 11 need to be carried, the occupied space is saved, which is beneficial to improving the stability of storage during the handling process, achieving the effect of facilitating handling.

[0027] There are support mechanisms rotatably connected inside both of the two support feet 11. The support mechanism includes two first support rods 17 which are respectively rotatably connected inside the two support feet 11. A first threaded adjustment rod 18 is slidably connected inside the two first support rods 17. On the sides of the two support feet 11 close to each other, a second support rod 19 and a second threaded adjustment rod 21 are respectively fixedly connected. The second threaded adjustment rod 21 is slidably connected inside the second support rod 19. A first adjustment ring 22 is rotatably connected inside both the second support rod 19 and the two first support rods 17. The three first adjustment rings 22 are respectively threadedly connected to the outer surfaces of the second threaded adjustment rod 21 and the two first threaded adjustment rods 18. A connecting seat 23 is rotatably connected inside the two first threaded adjustment rods 18. A threaded rod 24 is slidably connected inside the connecting seat 23. A second adjustment ring 25 is rotatably connected to the outer surface of the connecting seat 23. The second adjustment ring 25 is threadedly connected to the outer surface of the threaded rod 24. The upper end of the threaded rod 24 is fixedly connected with a rectangular seat 26. Two clamping blocks 27 are slidably connected inside the rectangular seat 26. By fitting the two support feet 11 to the I-beam of the construction building, the rectangular seat 26 and the clamping blocks 27 connected to the two support feet 11 cooperate to support and assist the steel bar truss floor slab, so as to play a role in temporarily supporting the steel bar truss floor. When the device is in use, the distance between the support frames can be adjusted by screwing the three first adjustment rings 22, improving the adjustability of the device. When the device is in use, the placement height of the rectangular seat 26 can be adjusted by screwing the second adjustment ring 25.

[0028] A bidirectional screw rod 28 is rotatably connected inside the rectangular seat 26. The two clamping blocks 27 are both threadedly connected to the outer surface of the bidirectional screw rod 28. When performing the clamping and supporting operation on the upper end of the floor slab by the clamping blocks 27, the bidirectional screw rod 28 can be rotated by screwing. During the rotation process of the bidirectional screw rod 28, the two clamping blocks 27 can be threadedly driven to slide in opposite directions inside the rectangular seat 26. Before the supporting operation, the placement distance between the two bidirectional screw rods 28 can be adjusted by screwing the clamping blocks 27, thereby further improving the flexibility of the device, adapting to different support condition requirements, and being beneficial to improving the adaptability of the device.

[0029] Aiming at the problems existing in the prior art, the utility model provides a steel bar truss floor slab support device. When it is necessary to carry and move the support device, the round rod 12 connected to one end of a group of support feet 11 is pushed into the first clamping block 14 of the other group of support feet 11. During the sliding process of the round rod 12, the first clamping block 14 and the second clamping block 15 are squeezed and rotated. When the round rod 12 contacts the inner wall of the first clamping block 14, the two compressed springs 16 lose the extrusion force. Under the action of the two springs 16, the first clamping block 14 and the second clamping block 15 are driven to rotate and reset to clamp the round rod 12. When it is necessary to carry the support feet 11, a plurality of support feet 11 are clamped together, saving the occupied space, being beneficial to improving the stability during storage in the carrying process, and achieving the effect of being convenient for carrying.

[0030] Working principle:

[0031] First step, fit the two supporting feet 11 with the I-beam of the construction building. The rectangular seat 26 and the clamping block 27 connected to the two supporting feet 11 cooperate to support and assist the steel bar truss floor slab, so as to play a temporary supporting role for the steel bar truss floor. When the device is used, the distance between the support frames can be adjusted by screwing the three first adjusting rings 22, improving the adjustability of the device. When the device is used, the placement height of the rectangular seat 26 can be adjusted by screwing the second adjusting ring 25.

[0032] Second step, when it is necessary to carry and move the support device before using the device or after the support work is completed, place the multiple supporting feet 11 on the same plane. Push the round rod 12 connected to one end of a group of supporting feet 11 into the first clamping block 14 of the other group of supporting feet 11. During the sliding process of the round rod 12, it squeezes the first clamping block 14 and the second clamping block 15 to rotate (the first clamping block 14 rotates in the connecting plate 13 through a rotating shaft, and the second clamping block 15 rotates in the first clamping block 14 through a rotating shaft). When the round rod 12 contacts the inner wall of the first clamping block 14, the two compressed springs 16 lose the extrusion force. Under the action of the two springs 16, the first clamping block 14 and the second clamping block 15 rotate and reset to clamp the round rod 12. When it is necessary to disassemble the two groups of supporting feet 11 during the next use, the round rod 12 can be manually pulled out of the first clamping block 14 for disassembly. By clamping the multiple supporting feet 11 together when it is necessary to carry the supporting feet 11, the occupied space is saved, which is beneficial to improving the stability during storage in the handling process, achieving the effect of convenient handling. When clamping and supporting the upper end of the floor slab through the clamping block 27, the two-way screw 28 can be screwed to rotate. During the rotation of the two-way screw 28, the two clamping blocks 27 can be threaded to slide in the rectangular seat 26 in opposite directions. Before the supporting operation, the placement distance between the two two-way screws 28 can be adjusted by screwing the clamping block 27, thereby further improving the flexibility of the device, adapting to different supporting condition requirements, and being beneficial to improving the adaptability of the device.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
