Problems solved by technology

[0002] During the pile foundation construction, the casing is usually put into the pile hole first, then the reinforcement cage is put into the casing, and then the concrete is poured in. There is no positioning device in the existing pile foundation construction process, and the reinforcement cage is very slow in the lowering process. It is easy to scrape the hole wall to cause the sedimentation layer to exceed the standard and pollute the reinforcement cage. Once the reinforcement cage is not positioned accurately, the thickness of the protective layer will also be inaccurate, which will affect the overall quality of the pile foundation. In addition, in the actual construction process, usually directly After hoisting the pile foundation casing, lower it into the pile hole. If the casing is deflected during the lowering process, the staff needs to adjust it. This process requires the cooperation of multiple workers, and the pile foundation casing itself Heavy self-weight, time-consuming and labor-intensive adjustment, low work efficiency

Abstract

The invention relates to a building pile foundation positioning device which comprises a bottom plate and a through hole which is formed in the bottom plate and allows a pile casing and a reinforcement cage to penetrate through, the bottom plate is fixed to the ground through a plurality of first bolts, and the building pile foundation positioning device is characterized in that a surrounding plate surrounding the through hole is arranged on the bottom plate, and a positioning mechanism is arranged in the surrounding plate; a plurality of guiding and positioning steel pipes are movably arranged on the pile casing, and the inner sides of the guiding and positioning steel pipes can abut against the outer wall of the reinforcement cage. According to the building pile foundation positioning device, positioning is more accurate in the lowering process of the pile casing and the reinforcement cage.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a positioning device for building pile foundations. Background technique [0002] During the pile foundation construction, the casing is usually put into the pile hole first, then the reinforcement cage is put into the casing, and then the concrete is poured in. There is no positioning device in the existing pile foundation construction process, and the reinforcement cage is very slow in the lowering process. It is easy to scrape the hole wall to cause the sedimentation layer to exceed the standard and pollute the reinforcement cage. Once the reinforcement cage is not positioned accurately, the thickness of the protective layer will also be inaccurate, which will affect the overall quality of the pile foundation. In addition, in the actual construction process, usually directly After hoisting the pile foundation casing, lower it into the pile hole. If the casing is ...
