Concrete centrifugal square pile and forming mold thereof

Abstract

The invention provides a concrete centrifugal square pile and a forming mold thereof. A pile body is in a square shape, a pile core is a central through hole and is cylindrical, corners of four sides of the pile body are in a stress relieving arc shape, the radius of arcs is the same, the pile body comprises a steel reinforcement cage and concrete, the steel reinforcement cage comprises a main skeleton reinforcement and stirrups, the stirrups are successively welded on the main skeleton reinforcement in a spiral mode, metal end plates which are connected with the steel reinforcement cage are arranged at two ends of the pile body, sleeve hoops are arranged on the connecting portions of the metal end plates and the pile body, and the radii R of the arcs of the corners of the four sides of the pile body are respectively 18mm, 22mm, 26mm and 32mm. The square pile has the advantages that materials are saved, the self weight is light, the square pile is not easy to damage, the tensibility of the pile body is good, the bearing capacity of the pile is large, the service life is long and bending resistance and shearing resistance performances are good. The structural pile of the forming mole is easy to demold, the energy is saved and the carbon emission is reduced.

Description

technical field [0001] The invention belongs to the construction field and relates to the improvement of the shape and structure of a foundation pile in the construction field. Specifically, it is a concrete centrifugal square pile and its forming mold. Background technique [0002] There are many existing prefabricated piles, such as concrete solid square piles, concrete hollow square piles, prestressed concrete pipe piles, prestressed hollow square piles, etc. Concrete solid square piles and concrete hollow square piles are usually non-prestressed prefabricated components, which occupy a large space for production and consume a lot of energy. The production of steel cages and concrete molding are mostly manual operations, the degree of mechanization is not high, and the quality is not easy to guarantee; bending performance Poor, hoisting, transportation, construction and transshipment are likely to cause cracks or even breakage in the pile body; Vibration is used to form,...

AI Technical Summary

Problems solved by technology

Because it is difficult to turn the bolts in place accurately by manual turning, the sealing performance of the tongue and groove plate is poor, and slurry leakage is prone to occur during the production and molding, resulting in the scrapping of the product
