Description

Technical Field

[0001] This utility model relates to the technical field of steel column installation adjusters, specifically to a cup-shaped foundation installation steel column shear-type tightening adjuster. Background Technology

[0002] In building construction, the installation of steel or concrete columns is of great significance. It is related to accurate positioning, verticality, support of the upper load, reasonable load transfer, and ensuring the safety and stability of the overall building structure.

[0003] In traditional cup-shaped foundation designs, temporary fixing of steel or concrete columns mainly relies on steel wedges or wooden wedges. However, the cup opening size varies greatly from project to project, and steel wedges need to be customized according to the cup opening. This makes the customization process extremely cumbersome, not only consuming a lot of time and energy, but also leading to a significant increase in costs. At the same time, it is also necessary to hoist the columns, and construction workers must simultaneously pay attention to the adjustment of the column position and verticality. The slightest negligence will make it difficult to meet the installation standards. Furthermore, after installation, the removal of steel or wooden wedges is also very difficult. These problems not only reduce construction efficiency and increase project costs, but also seriously threaten the safety of building structures. To address these issues, a cup-shaped foundation installation steel column shear tightening adjuster is proposed. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem that the temporary fixing of steel or concrete columns in the traditional cup-shaped foundation design mainly relies on steel wedges or wooden wedges, which has poor applicability and high cost. This utility model provides a scissor-type tightening adjuster for installing steel columns in a cup-shaped foundation.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A cup-shaped foundation for installing steel columns uses a scissor-type jacking adjuster. The cup-shaped foundation contains the steel column, and two symmetrically distributed adjusters are located inside. Each adjuster includes a channel steel (C1). Two channel steels (C1) are located inside the cup-shaped foundation. A screw is movably installed at the lower end of each channel steel (C1). A second channel steel (C2) is rotatably installed on the side of each channel steel (C1) via the screw. A scissor-type hand-cranked jack assembly is located between each channel steel (C1) and its adjacent second channel steel (C2). The scissor-type hand-cranked jack assembly includes a base. A base is fixedly installed on the inner wall of each channel steel (C1). Two inner support rods are rotatably mounted on the base. Limiting holes are opened on both sides of each channel steel. A connecting block is set between each pair of adjacent limiting holes. A limiting rod is fixedly mounted on each connecting block. The two ends of each limiting rod pass through the interior of the adjacent limiting hole. A top seat is fixedly mounted on each connecting block. Two inner support rods are rotatably mounted on each top seat. The free end of each inner support rod is rotatably connected to the free end of the corresponding inner support rod through a rotating shaft. A bidirectional lead screw is threadedly connected to each pair of adjacent rotating shafts. Each bidirectional lead screw is equipped with a rotating handle for driving the bidirectional lead screw to rotate.

[0006] The beneficial effects of this utility model are as follows: 1. This utility model places two sets of adjusters between the steel column and the inner wall of the cup-shaped foundation. After the two sets of adjusters are placed, the construction personnel adjust them to appropriately expand them. As the two sets of adjusters gradually expand, a stable supporting force is applied to the steel column. In this way, the verticality of the steel column can be accurately achieved, meeting the strict requirements of building construction, or achieving the purpose of fine-tuning the position of the steel column. If it is not necessary to temporarily fix the steel column, the two sets of adjusters can be appropriately retracted, allowing the construction personnel to quickly remove the adjusters from the inside of the cup-shaped foundation. This convenient removal operation greatly improves construction efficiency, and the adjusters can be reused, which not only reduces construction costs but also reduces material waste.

[0012] like Figure 1-6 As shown, a cup-shaped foundation for installing steel columns with shear-type tightening adjusters includes a cup-shaped foundation 1 for installing the steel column, a steel column 2 disposed inside the cup-shaped foundation 1, and two sets of symmetrically distributed adjusters 3 disposed inside the cup-shaped foundation 1, such as... Figure 1-6Specifically, the regulator 3 includes a channel steel 301, and two channel steels 301 are arranged inside the cup base 1. A screw 302 is movably installed inside the lower end of each channel steel 301. A second channel steel 303 is rotatably installed on the side of each channel steel 301 through the screw 302. A scissor-type hand-cranked jack assembly 304 is arranged between each channel steel 301 and the adjacent second channel steel 303. The scissor-type hand-cranked jack assembly 304 includes a base 401. A base 401 is fixedly installed on the inner wall of each channel steel 301. Two inner support rods 402 are rotatably installed on each base 401. Limiting positions are respectively opened on both sides of each second channel steel 303. Hole 409, with a connecting block 407 between each pair of adjacent limiting holes 409, and a limiting rod 408 fixedly installed on each connecting block 407. The two ends of each limiting rod 408 pass through the interior of the adjacent limiting hole 409. A top seat 406 is fixedly installed on each connecting block 407. Two inner support rods 403 are rotatably installed on each top seat 406. The free end of each inner support rod 403 is rotatably connected to the free end of the corresponding inner support rod 402 through a rotating shaft 404. A bidirectional lead screw 405 is threadedly connected to each pair of adjacent rotating shafts 404. Each bidirectional lead screw 405 is equipped with a rotating handle 410 for driving the bidirectional lead screw 405 to rotate.

[0013] More specifically, firstly, the steel column 2 is slowly placed inside the cup-shaped foundation 1, and the initial placement of the steel column 2 is confirmed to be accurate. Then, two channel steels 301 are placed between the steel column 2 and the inner wall of the cup-shaped foundation 1, so that the two channel steels 301 are tightly fitted to the inner wall of the cup-shaped foundation 1, and the two channel steels 303 are tightly fitted to the side wall of the steel column 2. Then, by rotating the handle 410, the two double-acting screws 405 are rotated, so that each pair of adjacent rotating shafts 404 moves closer to each other. At this time, each inner support rod 402 is clamped between the adjacent inner support rod 403. As the angle increases, each inner support rod 402 rotates a certain angle relative to the adjacent base 401, and each inner support rod 403 rotates a certain angle relative to the adjacent top seat 406. At the same time, the distance between each base 401 and the adjacent connecting block 407 increases, and each limiting rod 408 slides upward inside the corresponding limiting hole 409. As the angle between each channel steel 301 and the adjacent channel steel 303 gradually increases, a stable supporting force is applied to the steel column 2. In this way, the verticality of the steel column 2 can be accurately achieved, meeting the strict requirements of building construction, or achieving the purpose of fine-tuning the position of the steel column 2. If temporary fixation of the steel column 2 is no longer required, the two bidirectional lead screws 405 are rotated in opposite directions by rotating the handle 410, thereby moving each pair of adjacent rotating shafts 404 away from each other. At this time, the angle between each inner support rod 1 402 and the adjacent inner support rod 2 403 becomes smaller, and each inner support rod 1 402 rotates a certain angle corresponding to the adjacent base 401, while each inner support rod 2 403 rotates a certain angle corresponding to the adjacent top seat 406. At the same time, the distance between each base 401 and the adjacent connecting block 407 becomes smaller, and each limiting rod 408 slides downward inside the corresponding limiting hole 409. As the angle between each channel steel 1 301 and the adjacent channel steel 2 303 gradually decreases, the construction personnel can quickly remove the regulator 3 from the inside of the cup-mouth foundation 1. This convenient removal operation greatly improves construction efficiency, and the regulator 3 can be reused, which not only reduces construction costs but also reduces material waste.

[0014] In summary: First, slowly place the steel column 2 into the inside of the cup-shaped foundation 1 and confirm that the initial placement of the steel column 2 is accurate. Then, place the two sets of adjusters 3 into the inside of the cup-shaped foundation 1 in sequence, so that the two sets of adjusters 3 are respectively placed between the steel column 2 and the inner wall of the cup-shaped foundation 1. Then, arrange the two sets of adjusters 3 symmetrically around the central axis of the cup-shaped foundation 1 to ensure that the steel column 2 can be evenly stressed. After the two sets of adjusters 3 are placed, the construction workers adjust the two sets of adjusters 3 respectively, so that the two sets of adjusters 3 are appropriately unfolded. As the two sets of adjusters 3 are gradually unfolded, the two sets of adjusters 3 will tightly fill the gap between the steel column 2 and the cup-shaped foundation 1, and apply a stable supporting force to the steel column 2. In this way, the verticality of the steel column 2 can be accurately met, which meets the strict requirements of building construction. During construction, due to various factors, it may be necessary to make minor adjustments to the position of steel column 2. At this time, there is no need to rely on a crane. Just make appropriate adjustments to the two sets of adjusters 3 again to easily make minor adjustments to the position of steel column 2, effectively reducing labor input costs. If temporary fixation of the steel column 2 is no longer required, the construction workers adjust the two sets of adjusters 3 respectively, so that the two sets of adjusters 3 retract appropriately. At this time, the contact between the adjusters 3 and the inner wall of the cup-shaped foundation 1 and the steel column 2 gradually decreases, allowing the construction workers to quickly remove the adjusters 3 from the inside of the cup-shaped foundation 1. This convenient removal operation greatly improves the construction efficiency, and the adjusters 3 can be reused, which not only reduces construction costs but also reduces material waste.
