End plate assembly, concrete pile, end plate assembly machining method, pile production method and pile connecting method

Abstract

The invention relates to an end plate assembly. By longitudinally cutting extending sections of all workpiece inserting holes located in the middle of a first end plate body, first workpiece insertinggrooves, second workpiece inserting grooves and a polygonal penetrating hole are molded, and a cut complete block piece serves as a polygonal connecting plate; and in the state that a first end plateand a second end plate are spliced and the polygonal connecting plate is inserted into the polygonal penetrating hole, the first workpiece inserting grooves and the second workpiece inserting groovesare in butt joint to form the complete extending sections of the workpiece inserting holes. The end plate assembly has the advantages of being convenient to machine, high in efficiency, low in cost and capable of greatly saving materials, meanwhile, the weight of machined plates is further decreased, and thus industrialized mass production is possible. The invention further relates to a concretepile, an end plate assembly machining method, a pile production method and a pile connecting method.

Description

technical field [0001] The invention belongs to the technical field of pile foundation engineering of various building structure systems, and in particular relates to an end plate, a concrete pile with the end plate, a processing method of the end plate, a production method of the pile and a pile connection method. Background technique [0002] Concrete piles are generally equipped with end plates at both ends of the pile body. According to the different cross-sections of concrete piles, they can be divided into tubular piles, square piles, T-shaped piles, I-shaped piles, etc. The end plates are mainly used for connecting piles. , Anchoring the prestressed main tendons and tensioning the prestressed tendons of the reinforcement cage during the manufacture of concrete piles. [0003] The pile-connecting methods of existing concrete piles are mostly realized by manually welding the end plates. When connecting the piles, the end plates of two adjacent concrete piles are bonded ...

AI Technical Summary

Problems solved by technology

[0005] The end plate will not be made of casting material, because the strength of the casting material is not easy to break, so the end plate is generally made of rolled steel, and the above T-shaped end plate can only be processed by milling, so it is necessary to use High-thickness steel plate is processed, but the middle part of the concave-shaped end plate is not perforated, and the concave cavity can only be processed by milling. The milled material is completely wasted, and the processing is time-consuming and consumable.

Moreover, the processing of the two end plates is complicated. The T-shaped end plate needs to mill out the boss first, and then mill out the first groove for connecting piles on the periphery of the boss. The concave end plate must first mill out the concave cavity, and then Cut a perforation hole on the bottom of the cavity, and mill a second groove on the inner peripheral wall of the cavity for connecting piles, and finally drill a shear hole

The process is very complicated and inefficient, resulting in high processing costs and material costs. In reality, it is basically not feasible for commercial applications, and commercial applications are carried out. Therefore, the background patent has not been applied so far.
