Abstract

The invention belongs to the technical field of prefabricated components in the building industry, and relates to a variable-cross-section pile with end plates. The variable-cross-section pile comprises a pile body, a steel reinforcement cage is arranged in the pile body, the steel reinforcement cage comprises a plurality of vertical steel bars and a spiral-shaped spiral steel bar fixedly connected with the vertical steel bars, the pile body comprises a plurality of large-cross-section piles and small-cross-section piles mutually connected, two ends of the pile are respectively provided with an end plate, a plurality of tension nuts are fixedly in the end plates, two ends of the vertical steel bars are provided with pier heads whose external diameter is greater than the external diameter of the vertical steel bars, the pier heads are positioned in the tension nuts and can be clamped by the tension nuts, sidewalls of the tension nuts are also communicated with clamping holes, and the clamping holes are positioned on the end plates. According to the variable-cross-section pile, the connection of the pile body is firm, and the installation is convenient.

Description

technical field [0001] The invention belongs to the technical field of prefabricated parts in the construction industry, and relates to a prefabricated pile, in particular to a variable-section pile with an end plate. Background technique [0002] Due to the relatively poor quality stability of immersed tube piles, prefabricated prestressed concrete piles have developed rapidly in recent years. In the piling process, piles of different lengths should be selected according to different needs, which requires the piles to be connected to each other to form a longer pile body. [0003] The existing piles are connected by setting metal end plates at both ends of the piles. When two piles need to be connected, they are connected by welding the end plates of the two piles. The welding work is time-consuming and laborious, and the connection is inconvenient , In addition, the weld is easily corroded by the chloride salt in the soil, resulting in damage to the fastness of the joint ...
