Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, and more specifically, to a steel reinforcement cage positioning device. Background Art

[0002] Pile foundations are the main foundation forms of bridges and buildings. During the pile foundation construction process, the fabricated steel reinforcement cage needs to be lowered into the constructed pile hole. During the lowering process, there are strict requirements for the center deviation and protection layer of the steel reinforcement cage. The deviation of the steel reinforcement cage during the lowering process has a great impact on the construction. Especially when lowering the steel reinforcement cage in the form of pile-column connection structure, if the steel reinforcement cage is deviated during the lowering process, it will damage the retaining wall, and then cause the collapse of the hole; if the steel reinforcement cage is in a deviated state when it is lowered in place, the pile foundation needs to be reworked, resulting in a reduction in the construction speed and a waste of manpower and material resources, with great losses. In the existing technology, a steel reinforcement cage positioning device is usually used to position the lowered steel reinforcement cage. However, due to steel reinforcement cages with different diameters in actual work, the existing steel reinforcement cage positioning devices cannot adapt to different steel reinforcement cages.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a steel reinforcement cage positioning device, which solves the problem that the existing steel reinforcement cage positioning devices cannot be applied to steel reinforcement cages with multiple diameters.

One end of the slider away from the sliding groove is fixedly connected to the connecting ring.

[0007] In one embodiment, the fixing component includes a bolt. A moving groove communicating with the limiting groove is formed in the outer wall of the casing. The moving groove extends downward. The bolt is slidably connected to the moving groove. A threaded groove is formed through the limiting block, and the bolt is threadedly connected to the threaded groove.

[0008] In one embodiment, the positioning block is a cylindrical block, and the axis of the positioning block is perpendicular to the axis of the casing.

A connecting rod 12 is hinged in the connecting groove 11. The two ends of the connecting rod 12 extend into and out of the casing 1 respectively. A positioning block 121 is fixedly connected to the connecting rod 12 located inside the casing 1. A connecting ring 13 coaxial with the casing 1 is slidably connected to the outer wall of the casing 1. A connecting component is arranged on the connecting ring 13. The connecting component includes a U-shaped groove 1311. One end of the connecting rod 12 close to the connecting ring 13 is provided with a first hinge rod 1312.

A fixing component is arranged on the casing 1 to fix the position of the connecting ring 13.

[0017] During operation, the staff places the positioning device on the outside of the pile foundation and aligns the axis of the casing 1 with the axis of the pile foundation. When the connecting ring 13 is slid up and down, the angle between the connecting rod 12 and the casing 1 changes, and the diameter of the steel cage that the positioning block 121 can position changes. By sliding the connecting ring 13, the positioning block 121 is adjusted to the required position. The position of the connecting ring 13 is fixed by using the fixing component, then the position of the positioning block 121 is fixed. Then the steel cage is lifted and lowered into the pile foundation. During the lowering process, the side wall of the steel cage contacts the positioning block 121, so that the position of the steel cage will not shift.

By connecting the positioning blocks 121 to the connecting rod 12 and hinging the connecting rod 12 to the casing 1, when the angle between the connecting rod 12 and the casing 1 changes, the position of the positioning block 121 changes, and the diameter of the reinforcement cage that each positioning block 121 can position changes, facilitating the positioning of reinforcement cages with different diameters. By using the connecting ring 13 to connect the connecting rods 12 to each other and slidingly connecting the connecting ring 13 to the outer wall of the casing 1, when the connecting ring 13 slides up and down, the positions of all the positioning blocks 121 can be controlled simultaneously, making the movements of all the positioning blocks 121 synchronous and making the reinforcement cage co - axial with the casing.
