Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to an adjustable reinforcement device for pile cages of pile foundations. Background Art

[0002] Bored cast-in-place piles are widely used in civil engineering construction. With the progress of technology, large-diameter pile foundations are used more frequently. As an important part of bored cast-in-place piles, when hoisting the steel cage of large-diameter pile foundations, due to the large self-weight of the steel cage, it is very easy to deform during the hoisting process, which affects the quality of the formed pile. To ensure that the steel cage does not deform during hoisting, generally, strengthening rings are added inside the steel cage or triangular supports are used. Although this method can solve the problem, when the steel cage is lowered into the hole, the reinforced steel bars cannot be reused, resulting in great waste of materials.

[0003] In view of the above problems, the utility model provides an adjustable reinforcement device for pile cages of pile foundations that is convenient to disassemble. Content of the Utility Model

[0004] The utility model provides an adjustable reinforcement device for pile cages of pile foundations that is convenient to disassemble.

[0005] The purpose of the utility model is to provide an adjustable reinforcement device for pile cages of pile foundations, which includes a sleeve, a screw rod, a steel pipe and a fixed support. The end of the screw rod is processed by threading. The sleeve is installed at the threaded end of the screw rod. The steel pipe and the fixed support are welded into a whole and installed at the end of the sleeve.

[0006] Furthermore, the length of the screw rod is determined according to the installed steel cage.

[0007] Furthermore, the sleeve can be loosened by screwing outwards to release the fixed support.

[0008] The utility model has the following advantages: After being reinforced by this device, the steel cage can reduce deformation during transportation and will not bend during hoisting.

[0009] The utility model is convenient to install and disassemble, and can be recycled, achieving the effect of energy conservation and emission reduction. Description of the Drawings

[0011] Figure 2 It is an installation structural diagram of the utility model.

[0012] In the figure: 1. Sleeve; 2. Steel pipe; 3. Fixed support; 4. Screw rod. Detailed Description of the Invention

[0013] The utility model provides an adjustable reinforcement device for a pile foundation steel reinforcement cage, which comprises a sleeve 1, a screw rod 4, a steel pipe 2 and a fixed support 3. The end of the screw rod 4 is processed by threading. The sleeve 2 is installed at the threaded end of the screw rod 4. The steel pipe 2 and the fixed support 3 are welded into a whole and installed at the end of the sleeve 2.

[0014] In this embodiment, the length of the screw rod 4 is determined according to the installed steel reinforcement cage.

[0015] In this embodiment, the sleeve 1 is loosened by screwing outwards to fix the support 3.

[0016] In this embodiment, after the steel reinforcement cage is processed, a pair of such devices are placed at intervals. By screwing out the sleeve 1 outwards, the fixed support 3 is closely attached to the main steel bars of the steel reinforcement cage to achieve the purpose of fixing the steel reinforcement cage.

[0017] In this embodiment, when the steel reinforcement cage is transported to the site and during the lowering process, by reversely screwing the sleeve 1, the fixed support 3 is loosened one by one. The fixed support 3 and the sleeve 1 retreat synchronously until the fixed support 3 disengages from the main steel bars of the steel reinforcement cage, and the whole device is taken out.

[0018] Although the specific implementation mode of the utility model has been described in detail with reference to the accompanying drawings, it should not be construed as a limitation to the protection scope of the utility model. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative work still fall within the protection scope of the utility model.
