Concrete pile stretching and connecting device

Abstract

The invention relates to a concrete pile stretching and connecting device. The concrete pile stretching and connecting device comprises a moving plate and a guiding plate, and the moving plate and the guiding plate are each provided with multiple fixing holes; and a sliding protrusion is arranged on the moving plate, and the sliding protrusion is fixedly clamped in a guiding fixing slot of the guiding plate in a sliding manner. According to the concrete pile stretching and connecting device, the guiding fixing slot is used for fixed clamping, the two ends of the guiding fixing slot are opened, when the device is used, the sliding protrusion on the moving plate slides into the guiding fixing slot and is fixedly clamped at the central position, and then the device is put into a concrete pile mold; after a concrete pile is completed, disassembling can be completed only by moving the moving plate to enable the sliding protrusion to be moved out of the guiding fixing slot, operation is very convenient, separation is completed through machinery, and manual operation can be completely avoided. Compared with an existing manual fastening bolt, by means of the concrete pile stretching and connecting device, automatic production of concrete piles can be achieved, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a concrete pile tension connection device, which belongs to the field of building material production. Background technique [0002] With the development of concrete technology, the technology of concrete pipe piles is becoming more and more mature. In addition to being used in industrial and civil buildings, it is also widely used in various fields such as bridges, ports, railways or water conservancy projects. [0003] During the production of concrete pipe piles, it is necessary to perform prestressed tensioning on the steel wire cage in the pipe pile mold. In the current tensioning system, the tension force is directly transmitted to the end plate, which is uneven in force and prone to eccentricity. The prestress of steel wire cage PC rods after forming is inconsistent, and the tensile, compressive and shearing capabilities of pipe piles are all affected. [0004] And when concrete pipe piles with different lengths are req...

Problems solved by technology

[0003] During the production of concrete pipe piles, it is necessary to perform prestressed tensioning on the steel wire cage in the pipe pile mold. In the current tensioning system, the tension force is directly transmitted to the end plate, which is uneven in force and prone to eccentricity. After forming, the prestress of steel wire cage PC rods is inconsistent, and the tensile, compressive and shearing capabilities of pipe piles are all affected

[0004] And when concrete pipe piles with different lengths are required, it would be too costly to manufacture a set of molds for each length of concrete pipe piles. At present, it is often used to use connectors in one long concrete pipe pile mold to produce two molds at the same time. Concrete pipe piles are mostly fixed by bolts in the prior art. Although the fixing force is sufficient, manual disassembly and installation are required every time, requiring more manpower, and automatic production cannot be realized.
