Hanging and fixing device and construction method for cast-in-situ pile reinforcement cage

Abstract

The application relates to a cast-in-place pile reinforcement cage hanging and fixing device and its construction method, which belong to the field of building construction. The key point of the technical solution is to include a base, which is located above the pile hole for placing the reinforcement cage, and is fixedly connected to the ground. There are placement holes for hoisting the reinforcement cage into the pile hole on the top, and a fixing assembly for fixing the reinforcement cage is provided on the base. The fixing assembly includes two abutment rods, and the two abutment rods are along the direction of the centerline of the pile hole Symmetrically arranged, the length direction of the abutment rod is the same as the radial direction of the steel cage, the abutment rod is slidably connected to the base, and a driving device for driving the two abutment rods to approach or move away is provided between the abutment rod and the base. In the present application, when assembling two adjacent reinforcement cages, it is not necessary to dismantle the workpieces for clamping the reinforcement cages, so the operation is simple and the work efficiency is high.

Description

technical field

[0001] The present application relates to the field of building construction, in particular to a hanging and fixing device for a cast-in-place pile reinforcement cage and a construction method thereof. Background technique

[0002] At present, in the pile foundation construction of bridges, high-rise buildings or high-speed railways, it is necessary to dig deep pile holes first, and then put a reinforcement cage in the pile holes and then pour cement to form a reinforced concrete structure. Because the pile holes are very deep, the reinforcement cages need to be fabricated in sections, and then lowered into the pile holes by a crane, and the main bars on the two reinforcement cages are manually screwed through the connecting sleeves to form a reinforcement skeleton.

[0003] At present, in the related art, the existing Chinese patent with the notification number CN211080207U can be referred to, which discloses a long pile foundation reinforcement cage install...
