Abstract

The invention discloses a pile foundation reinforcement cage position control device and an installation method, and belongs to the field of reinforcement cage positioning. The pile foundation reinforcement cage position control device comprises a positioning frame and a reinforcement cage; multiple sets of connecting pieces are installed in the positioning frame; the upper ends of the multiple sets of connecting pieces are connected with the positioning frame; a bearing part, a connecting part and a limiting part are installed at the bottom end of each connecting piece; the bearing parts are suitable for supporting stirrups of the reinforcement cage; the connecting parts are suitable for being connected to a main reinforcement of the reinforcement cage; the connecting parts are installed between the bearing parts and the limiting parts; the connecting parts are movably connected to the connecting pieces; the limiting parts are installed at the upper ends of the connecting parts; the limiting parts are suitable for limiting the positions of the stirrups of the reinforcement cage; a pile foundation hole is formed in the lower portion of the positioning frame; and the reinforcement cage is installed in the pile foundation hole. The technical problems that the reinforcement cage cannot be effectively fixed and cannot be limited to float upwards during pouring, and hoisting of the reinforcement cage is inconvenient are solved.

Description

technical field [0001] The invention belongs to the field of reinforcement cage positioning, and in particular relates to a position control device and an installation method of a pile foundation reinforcement cage. Background technique [0002] As a commonly used substructure form in engineering construction, bored piles are widely used. The hoisting of the pile foundation reinforcement cage will directly affect the quality of the pile foundation and the supporting effect of the pile foundation design. [0003] In the construction of the project, it is stipulated that the steel frame should not be directly supported at the bottom of the hole, but should be hung at the designated position in the design. The conventional hanging method is to use wire rope to hang it on the steel casing of the hole. The steel wire rope is easily deformed, causing the reinforcement cage to sink. During the concrete pouring process, the extubation and the buoyancy of the concrete pouring will ca...
