Building foundation pile fastening device

Technical Field

The application relates to the technical field of building construction, in particular to a building foundation pile fastening device.

Background

In the construction process of the building, the construction of the building foundation is required to be carried out firstly; a foundation pit is dug on the ground, and then foundation piles are buried in the foundation pit to bear a building, and the stable building foundation piles are important foundations and guarantees for the quality of the building, so that the construction process of the building foundation piles needs to be continuously optimized.

For the construction of foundation piles, at present, there are two general methods, one is to bury a reinforcement cage in a foundation pit and then cast concrete in situ to form a foundation pile; the other method is to prefabricate the foundation pile in a factory, then transport the prefabricated foundation pile to a construction site, place the prefabricated foundation pile into the foundation pit through a crane, and then pour concrete between the outer side wall of the foundation pile and the inner side wall of the foundation pit, so that the foundation pile and the foundation pit are integrally fixed and are commonly used in the construction engineering of the fabricated building.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: in the process of putting the prefabricated foundation pile into the foundation pit, the diameter of the foundation pit is larger than that of the foundation pile, so that the foundation pile is difficult to be placed in the center of the foundation pit, and after the foundation pile is embedded and finished, the foundation pit is stressed unevenly, and potential safety hazards exist. Therefore, improvements are needed.

SUMMERY OF THE UTILITY MODEL

In order to improve the precision that precast foundation pile was buried underground, this application provides a building foundation pile fastener.

The application provides a building foundation pile fastener adopts following technical scheme:
