Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a device for adjusting and unloading the elevation of a bottom formwork support system. Background Technology

[0002] In the construction of cast-in-place concrete structures, the elevation accuracy of the bottom formwork support system (such as full-span scaffolding and steel supports) directly affects the quality of structural forming, while the safety and convenience of subsequent dismantling are related to construction efficiency.

[0003] Traditional adjustment methods (such as jacks and sandboxes) have the following drawbacks:

[0004] 1. Low adjustment precision: Relying on manual tapping or rough turning, it is difficult to meet the precision requirements;

[0005] 2. High risk of falling off: It requires removing the pads or cutting the supports, which is complicated and can easily cause the support system to become unstable;

[0006] 3. Poor durability: The sand box is easily contaminated by concrete or corroded, which can cause adjustment to become stuck.

[0007] Therefore, there is an urgent need for a device that allows for precise adjustment, controllable unloading, and structural durability for adjusting and unloading the elevation of the bottom formwork support system. Utility Model Content

[0008] To address the problems of low adjustment accuracy, high risk of falling off, and poor durability in existing bottom formwork support systems, this utility model provides a device for adjusting and lowering the elevation of a bottom formwork support system.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A device for adjusting and lowering the elevation of a bottom formwork support system, comprising:

[0011] The system comprises two sets of symmetrically distributed support blocks, two sets of symmetrically distributed adjustment blocks, and a pull-out assembly connecting the two sets of adjustment blocks. The adjustment blocks are located between the two sets of support blocks, and there is a wedge-shaped mating surface between the adjustment blocks and the support blocks. The pull-out assembly includes two screw rods, which are detachably connected to each other by a connecting kit. One end of each screw rod is fixedly connected to an end cap, and a fine-tuning nut is threadedly connected to the end cap of each screw rod, and the fine-tuning nut is located on the outside of the adjustment block.

[0012] As a further limitation of the above scheme:

[0013] Both the support block and the adjustment block are isosceles trapezoidal structures.

[0014] As a further limitation of the above scheme:

[0015] The inclination angle of the wedge-shaped mating surface is 30°-60°.

[0016] As a further limitation of the above scheme:

[0017] Several annular openings are provided at the opposite ends of the two screw components, and an annular block corresponding to the annular openings is provided on the inner side of the connecting kit.

[0018] As a further limitation of the above scheme:

[0019] The connecting kit includes two semi-cylindrical parts, which are fixedly connected by screws.

[0020] As a further limitation of the above scheme:

[0021] The pull-out assembly is provided in two sets.

[0022] As a further limitation of the above scheme:

[0023] Both the support block and the adjustment block are plate frame structures.

[0024] As a further limitation of the above scheme:

[0025] The support block has limiting parts on both sides of its inclined surface, and the adjusting block is located between the two limiting parts.

[0026] The beneficial effects of this utility model are:

[0027] This invention, through an improved structure of the pull-pull assembly, allows for the approximate determination of the distance between the two adjusting blocks by the connecting kit, corresponding to the overall height between the two sets of support blocks. In actual use, the distance between the two adjusting blocks is further adjusted by the fine-tuning nut, achieving fine-tuning of the height of the top of the support blocks. Compared to traditional bottom mold support systems, it offers higher adjustment precision. Furthermore, the screw component has an end-limiting fine-tuning nut, preventing safety hazards during use (the fine-tuning nut falling off and causing structural instability due to the two sets of support blocks and the two sets of adjusting blocks). Moreover, all components are made of metal, minimizing environmental impact and exhibiting high durability. Attached Figure Description

[0036] Please refer to the attached document. Figure 1 - Figure 5 This application illustrates a device for adjusting and removing the elevation of a bottom formwork support system, which is applicable to the elevation control and subsequent removal of bottom formwork supports in the construction of concrete structures such as bridges and building floor slabs. Specifically, it includes: two sets of support blocks 1 symmetrically distributed, two sets of adjustment blocks 2 symmetrically distributed, and a tie assembly 3 connected between the two sets of adjustment blocks 2.

[0037] Adjusting block 2 is located between two sets of support blocks 1, and there is a wedge-shaped mating surface between adjusting block 2 and support block 1. Pull assembly 3 is connected between the two sets of adjusting blocks 2, such as... Figure 1 , Figure 2 The two sets of support blocks 1 and two sets of adjustment blocks 2 shown are distributed on the four sides of a square. The distance between the two adjustment blocks 2 is adjusted by the pull assembly 3. Under the action of the wedge-shaped mating surface, the vertical distance between the two support blocks 1 is adjusted to achieve support and adjustment of the bottom formwork during construction. During the later unloading operation, it is only necessary to adjust the pull assembly 3 to be longer, increase the distance between the two adjustment blocks 2, and reduce the vertical distance between the two support blocks 1 (the lower support block 1 is supported on a fixed bracket, and the actual adjustment process is that the upper support block 1 moves down).

[0038] This embodiment specifically designs a pull assembly 3, which includes: two screw rods 301, which are detachably connected to each other by a connecting kit 305. The opposite ends of the two screw rods 301 are fixedly connected to end heads 302, and a fine-tuning nut 303 is threadedly connected to the screw rods 301 near the end heads 302. The fine-tuning nut 303 is located on the outside of the adjusting block 2.

[0039] In use, the distance between the two adjusting blocks 2 is roughly determined by the connecting kit 305, corresponding to the overall height between the two sets of support blocks 1. The distance between the two adjusting blocks 2 is further adjusted by the fine-tuning nut 303 to fine-tune the height of the top of the support block 1. Compared with the traditional bottom mold support system, its adjustment accuracy is high. Moreover, the screw 301 has an end 302 to restrict the fine-tuning nut 303, so that there will be no safety hazards during use (the fine-tuning nut 303 will fall off and cause the structure composed of the two sets of support blocks 1 and the two sets of adjusting blocks 2 to become unstable). In addition, all structures are metal components, so they are less affected by the environment during use and have high durability.

[0040] In one embodiment, both the support block 1 and the adjustment block 2 are isosceles trapezoidal structures. Thus, the adjustment block 2 and the two support blocks 1 can form two wedge-shaped mating surfaces, which are relatively symmetrical and provide more stable adjustment.

[0041] In one embodiment, the inclination angle of the wedge-shaped mating surface is 30°-60°. This angle range allows the horizontal adjustment amount to be efficiently converted into vertical elevation change (vertical adjustment amount = horizontal adjustment amount × tanθ), balancing adjustment accuracy and ease of operation.

[0042] In one embodiment, a plurality of annular openings 304 are provided at one end of the two screw members 301 facing each other, and an annular block corresponding to the annular openings 304 is provided on the inner side of the connecting kit 305, so that the connection between the screw members 301 and the connecting kit 305 can be more stable.

[0043] When installing the connecting kit 305, insert the annular opening 304 at the appropriate position into the inside of the connecting kit 305 so that the lengths of the two screw parts 301 meet the actual usage requirements.

[0044] In one embodiment, the connecting kit 305 includes two semi-cylindrical parts that are fixedly connected by screws, which facilitates the connection operation of the connecting kit 305.

[0045] In one embodiment, two sets of pull-up components 3 are provided, and the pull-up components 3 are arranged side by side in the horizontal direction to make the structure more stable.

[0046] In one embodiment, both the support block 1 and the adjustment block 2 are plate frame structures. Plate frame structures are lightweight, strong, and easy to carry.

[0047] In one embodiment, a limiting part 1a is provided on both sides of the inclined surface of the support block 1, and the adjusting block 2 is located between the two limiting parts 1a. The limiting part 1a is used to limit the lateral offset sliding of the adjusting block 2, so as to ensure the stability of the wedge-shaped mating surface and avoid safety accidents.
