Description

Technical Field

[0001] This utility model relates to the field of concrete pile foundation technology, specifically to a lattice column torsion adjustment and limiting device. Background Technology

[0002] Lattice columns are a type of building structure with strong bending resistance. Their characteristic feature is the distribution of material area further away from the axis of inertia, which enhances the bending resistance of components under the same axial resistance while saving materials. In subway station construction, lattice columns are often used in conjunction with bored piles to form vertical support columns. During construction, bored piles are typically drilled first, followed by the lowering of the reinforcing cage. Then, the lattice columns are lowered and welded to the cage, and finally, concrete is poured. During hoisting, the orientation of the lattice columns must be strictly controlled. Otherwise, if the column twists after concrete pouring, it will be impossible to weld to the subsequent support system, affecting the stress and safety of the foundation pit retaining structure. Since twisting of lattice columns occurs relatively frequently and subsequent treatment and repair are difficult, controlling the installation direction of the lattice columns is extremely important.

[0003] The existing process for hoisting and installing lattice columns involves inserting reinforcing bars into the gaps between the columns during hoisting, and then adjusting the columns using these bars. This existing process is quite dangerous. During adjustment, the lattice columns can twist uncontrollably, making it difficult to control their direction. Furthermore, once the columns are lowered to the design elevation, there are no measures in place to ensure their stability; the existing process does not address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a lattice column torsion adjustment and limiting device. By setting multiple sets of adjustment components clamped around the lattice column body, the direction of the lattice column body can be adjusted more conveniently and safely through the fixing rod. After the direction is adjusted, the position of the adjustment rod can be adjusted to limit and fix the lattice column body and the steel casing, so as to avoid subsequent construction from affecting it and causing it to twist and misalign again, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A torsion adjustment and limiting device for a lattice column includes an adjustment assembly. The adjustment assembly includes two sets of symmetrically arranged clamping plates, which are slidably mounted on a fixed plate. Multiple sets of strong springs are arranged between the clamping plates, and the two ends of the strong springs are respectively fixedly connected to the two sets of clamping plates. A fixed rod is fixedly installed in the middle of one side of the fixed plate, and an adjustment thread is welded to one end of the fixed rod. The adjustment thread is threadedly connected to the adjustment rod.

[0007] Preferably, the clamping plate abuts against both sides of the lattice column body, and a first rubber pad is adhered to the side of the clamping plate that contacts the lattice column body.

[0008] Preferably, one end of the adjusting rod abuts against the inner wall of the steel casing, and a second rubber pad is provided between the adjusting rod and the steel casing, the second rubber pad being adhered to the adjusting rod.

[0009] Preferably, a limiting block is fixedly installed on the side of the clamping plate that contacts the fixing plate, and a limiting groove is formed on the surface of the fixing plate, with the limiting block slidingly engaging with the limiting groove.

[0010] Preferably, the adjustment component is disposed between the lattice column body and the steel casing, the lattice column body is located inside the reinforcing cage, and a sling is installed on the top of the lattice column body.

[0011] Preferably, the steel casing is disposed on the outside of the reinforcing cage, and the lattice column body, the steel casing and the reinforcing cage are coaxially arranged.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses multiple sets of adjustment components clamped around the lattice column body. Its simple structure and ease of use allow for convenient and safe adjustment of the lattice column body's orientation via fixing rods. After orientation adjustment, the position of the adjusting rods can be used to limit and fix the lattice column body to the steel casing, preventing subsequent construction from causing further torsion and misalignment. This significantly reduces the quality issues associated with lattice column body torsion, thus improving the welding of the foundation pit retaining structure to the lattice column and enhancing the safety of the foundation pit.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 This utility model provides a technical solution:

[0023] A torsion adjustment and limiting device for a lattice column includes an adjustment component 1, which is disposed between the lattice column body 2 and the steel casing 3. The adjustment component 1 includes two sets of symmetrically arranged clamping plates 101, which are slidably mounted on a fixed plate 103. Multiple sets of strong springs 102 are arranged between the clamping plates 101, and the two ends of the strong springs 102 are respectively fixedly connected to the two sets of clamping plates 101. A fixed rod 108 is fixedly installed in the middle of one side of the fixed plate 103. The clamping plates 101 abut against both sides of the lattice column body 2. A first rubber pad 104 is adhered to the side of the clamping plate 101 that contacts the lattice column body 2. A limiting block 109 is fixedly installed on the side of the clamping plate 101 that contacts the fixed plate 103. A limiting groove 110 is formed on the surface of the fixed plate 103, and the limiting block 109 slides with the limiting groove 110.

[0024] By sliding the clamping plate 101 onto the fixed plate 103, and through the sliding engagement of the limiting block 109 and the limiting groove 110, the clamping plate 101 can flexibly slide along the fixed plate 103. The engagement of the limiting block 109 and the limiting groove 110 further restricts the sliding range of the clamping plate 101, ensuring that it accurately abuts against both sides of the lattice column body 2, adapting to lattice column bodies 2 of different sizes or with slight deviations in position. Multiple sets of strong springs 102 are set between the two sets of symmetrically arranged clamping plates 101, and the elastic force of the strong springs 102 is used to clamp the plates. The plate 101 is tightly clamped on both sides of the lattice column body 2, which not only fixes the lattice column body 2 and prevents it from shaking or shifting during installation or when subjected to external forces, but also adapts to the slight deformation that may occur in the lattice column body 2 to a certain extent, ensuring stable clamping of the lattice column body 2. The side of the clamping plate 101 that contacts the lattice column body 2 is bonded with a first rubber pad 104, which can effectively protect the surface of the lattice column body 2 from being scratched by the clamping plate 101, and at the same time can increase the friction between the clamping plate 101 and the lattice column body 2, thereby improving the stability of the clamping.

[0025] One end of the fixing rod 108 is welded with an adjusting thread 107, which is threadedly connected to the adjusting rod 106. One end of the adjusting rod 106 abuts against the inner wall of the steel casing 3. A second rubber pad 105 is provided between the adjusting rod 106 and the steel casing 3 and is bonded to the adjusting rod 106. The reinforcing cage 4 is set on the outside of the lattice column body 2. A sling 5 is installed on the top of the lattice column body 2. The steel casing 3 is set on the outside of the reinforcing cage 4. The lattice column body 2, the steel casing 3 and the reinforcing cage 4 are coaxially arranged.

[0026] By threading the adjusting screw 107 at one end of the fixed rod 108 to the adjusting rod 106, the adjusting rod 106 can be easily pushed against the steel casing 3 by rotating it, thereby limiting the position of the lattice column body 2 and preventing subsequent construction from causing it to twist and misalign again. This greatly reduces the quality problem of directional torsion of the lattice column body 2, thus making the foundation pit retaining structure and the lattice column body 2 better welded, improving the safety of the foundation pit. The second rubber pad 105 between the adjusting rod 106 and the steel casing 3 not only avoids direct contact between the adjusting rod 106 and the steel casing 3, causing wear, but also increases the friction when the adjusting rod 106 touches the steel casing 3, enhancing the overall stability and reliability of the device.

[0027] In practical use, move the device to the designated position, use a tool to spread the clamping plate 101 to both sides, stretch the strong spring 102, then move the clamping plate 101 to both sides of the lattice column body 2. After releasing the clamping plate 101, under the action of the elastic force of the strong spring 102, the clamping plate 101 clamps the two sides of the lattice column body 2. The two sets of adjusting components 1 are symmetrically clamped on both sides of the lattice column body 2. Then, the other two sets of clamping components are clamped together with the first two sets of clamping components on the lattice column body. At different height positions on both sides of the lattice column body 2, the lattice column body 2 is then hoisted. The operator can control the direction of the adjusting component 1 and the lattice column body 2 through the adjusting rod 106 and the fixing rod 108, thereby preventing the direction of the lattice column body 2 from twisting. After the lattice column body 2 is hoisted to the design elevation, the adjusting rod 106 is rotated to move the adjusting rod 106, which is threaded to the adjusting screw head 107, outward, thereby pressing against the inner wall of the steel casing 3, thereby fixing and limiting the lattice column body 2.
