A cast-in-situ pile reinforcement cage lowering device

Abstract

The invention discloses a cast-in-situ pile reinforcement cage lowering device. For the construction work of lowering the cast-in-situ pile reinforcement cage, the sliding connection between the convex chute and the convex slider arranged equidistantly on the suspension plate is carried out. Setting, driving the position of the placement pipe to change, for the fixing of the steel cage during the lowering work, the corresponding fixing and placement work can be carried out according to the different diameters of the steel cage and the thickness of the steel bar, and then the lowering work can be carried out according to the actual situation of the steel cage to improve the work. Efficiency, speed up the construction progress of the project, and then improve the economic benefits of the work. Through the strengthened fixing mechanism set on the placement pipe, it can improve the placement and fixing firmness of the steel cage and the connection strength during the lowering of the steel cage to ensure that the lowering work The stability of the steel cage in the process can avoid the occurrence of dangerous accidents.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a lowering device for cast-in-place pile reinforcement cages. Background technique [0002] With the rapid development of my country's construction projects, especially high-rise buildings, the processing of foundations, my country's construction projects have begun to use the concrete pouring pile foundation technology in bridge construction; There are various forms, but cast-in-situ piles are widely used in the construction of high-rise buildings on soft foundations; at the same time, due to construction period and cost reasons, construction units often require pile foundations to be started without excavation of the earthwork on site. Construction. During the construction process, cast-in-situ piles are widely used in construction due to their advantages of no vibration, no soil extrusion, low noise, and suitable for use in densely built urban areas durin...

Problems solved by technology

[0003] For the work below the existing reinforcement cage, it is usually completed by hoisting with a crane. For the work of hoisting the reinforcement cage below, on the one hand, when working under the reinforcement cage in the prior art, the connection and fixation stability and firmness of the reinforcement cage are not enough. , when working below, it may loosen and cause dangerous accidents. On the other hand, when hoisting the lower device, it cannot be adjusted and fixed according to the cage diameter of the steel cage and the size of the steel bar, and thus the construction cannot be carried out according to the actual construction situation. , causing inconvenience to the bottom of the steel cage, affecting the construction efficiency, delaying the construction progress, and further affecting the economic benefits of the construction work. For this reason, the present invention proposes a cast-in-situ pile reinforcement cage lowering device to solve the above problems
