Description

Technical Field

[0001] The utility model relates to the field of pile foundation reinforcement cage lowering construction, in particular to a double-layer reinforcement cage lowering fixed driving plate. Background Art

[0002] At present, the lowering tooling of the pile foundation reinforcement cage is mainly completed in the following ways:

[0003] 1. Steel fixing device: A square steel frame is set in the pile hole. When the steel cage is lowered into place, two parallel I-beams or channel steels are passed under the reinforcing stirrups to support the entire steel cage on the positioning frame. Then remove the lifting rope and continue to install the next section of the steel cage. After pouring concrete, this method requires cutting off the supporting steel to complete the disassembly of the device, which is cumbersome. In the construction of pile foundations that require the lowering of double-layer steel cages, when lowering the inner cage, two parallel steels should be centered to hinder it. This method cannot be used. In the face of pile foundations with extra-long and extra-large pile diameters, the amount of steel used will increase, and there will be problems with uneven load distribution, low efficiency, and great safety hazards.

[0004] 2. Tie rod fixing device: Pile hole, a steel casing is provided in the pile hole, there is no steel cage in the steel casing, a fixer is provided on the side of the steel cage, the fixer includes a bracket, two rings are provided at the lower end of the bracket, the ring surface is arranged obliquely downward, the transverse steel bars of the steel cage are between the rings, a movable plug rod is inserted between the rings, and the upper end of the bracket is connected to the fixed rod in the ground through a connecting rod. The steel cage is fixed by the fixer, the sleeve of the bracket is clamped on a transversely arranged steel bar of the steel cage, and the movable plug rod is inserted to fix the steel cage, and then the concrete is poured. After the pouring is completed, the movable plug rod is pulled out, and then the bracket is pulled out. This uses a large number of rods. When facing super-long piles and super-large pile diameter pile foundations, the rods are subjected to excessive tensile stress, which poses a great safety hazard, and other fixing methods are still required when lowering the inner cage.
