Description

Technical Field

[0001] The present application relates to the field of building construction support, and in particular to an adjustable support device for a pile foundation reinforcement cage. Background Art

[0002] The main role of the steel cage is the same as the stress on the longitudinal steel bars of the column. It mainly plays a tensile role and restrains the pile concrete so that it can withstand a certain axial tension. During the construction of bridges, culverts or high-rise buildings, the foundation may be required to be piled according to requirements. The method is to use machine punching and water drilling, and the hole depth meets the design requirements. Then, the steel cage is lowered into the pile hole, and the guide tube is inserted to pour concrete.

[0003] When placing steel cages in some deeper pile foundation pits, since the length of the steel cages cannot meet the depth of the pile foundation pits, the steel cages are usually placed in the pile foundation pits first, and then cross bars are used to pass through the steel cages, so that a small part of the steel cages remains outside the pile foundation pits. Then the new steel cages are hoisted and welded to each other to lengthen the overall length of the steel cages to meet the deeper pile foundation pits.

[0004] When keeping a small part of the steel cage outside the pile foundation pit, cross bars are generally used to pass through the steel cage directly, and then the steel cross bars are placed on the supporting steel pipes of the impact pit to support the steel cage. When the cross bars are used to support the steel cage, there is a lack of fixation between the steel cage and the cross bars. When the cross bars support the steel cage, the steel cage and the cross bars may move, causing deviations in the steel cage during welding. Utility Model Content

[0005] The purpose of the present application is to solve the problem raised in the above background technology that when the cross bars are used to support the steel cage, there is a lack of fixation between the steel cage and the cross bars. When the cross bars support the steel cage, the steel cage and the cross bars may move, resulting in deviation of the steel cage during welding. The present application provides an adjustable support device for a pile foundation steel cage.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0010] By adopting the above technical solution, the steel cage is placed in the middle of the support frame, and then the two-way threaded rod is rotated to allow the two support rods to clamp the steel cage, and then the resistance block supports the steel cage, and then the adjustment component is used to clamp the steel cage, so that the steel cage can remain stable when being supported, reducing the possibility of the steel cage being offset when welding the steel cage, and facilitating the support of steel cages of different diameters.

[0011] Furthermore, an adjustment rod is fixed on the support rod, and two symmetrical interference rods are slidably connected to the adjustment rod.

[0012] By adopting the above technical solution, the two interference rods are moved on the adjustment rod, and the two interference rods clamp the steel cage, thereby further improving the stability of the steel cage when it is supported.

[0017] Furthermore, the clamping assembly includes two clamping moving blocks slidably connected to the connecting block, and the connecting block is rotatably connected to a two-way threaded rod three, which passes through the two clamping moving blocks and is threadedly connected to the two clamping moving blocks.

[0018] By adopting the above technical solution, the two-way threaded rod drives the two clamping moving blocks to move simultaneously, and the two clamping moving blocks drive the corresponding clamping fixed blocks, so that the support frame and the supporting steel pipe can be easily aligned.

[0019] Furthermore, both of the clamping and fixing blocks are provided with V-shaped grooves.

[0021] Furthermore, the bottoms of the two clamping and fixing blocks are rotatably connected to a plurality of movable rollers.

[0022] By adopting the above technical solution, when the clamping movable block drives the clamping fixed block to move, the clamping fixed block drives the movable roller, and the movable roller rolls on the ground, thereby reducing the friction between the clamping fixed block and the ground and facilitating the movement of the clamping fixed block.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application uses a lifting device to pass the steel cage through the supporting steel pipe and into the pile foundation pit. When most of the steel cage enters the pile foundation pit, the two-way threaded rod is rotated to drive the two support rods. The two support rods are close to each other under the support of the sliding rod. Then the interference blocks fixed on the two support rods enter under the annular ribs of the steel cage on the steel cage. The two interference blocks support the steel cage, and the two support rods clamp the steel cage. Then the two-way threaded rod 2 is rotated. Driven by the two-way threaded rod 2, the two interference rods are close to each other on the adjusting rod. The two interference rods clamp the steel cage, thereby achieving the purpose of allowing the steel cage to remain stable when supported, reducing the possibility of the steel cage deflecting when welding the steel cage, and facilitating the support of steel cages of different diameters.
