Device and method for preventing wire pipe from being blocked

Abstract

The invention discloses a device and method for preventing a wire pipe from being blocked. The device comprises a prefabricated part body, a plurality of wire boxes are buried in the surface of the prefabricated part body, a wire pipe is buried between the two wire boxes, and a pull wire is movably arranged in the wire pipe in a penetrating mode; and a pipe connecting device is arranged between the two ends of the wire pipe and comprises a pipe barrel, the two ends of the pipe barrel are each fixedly connected with two arc-shaped threaded plates, and the surfaces of the two arc-shaped threaded plates are sleeved with a same threaded turncap in a threaded mode. According to the invention, a plurality of wire pipes and a plurality of pipe connecting devices are used for connecting the wire pipes, so that the combined wire pipes reach different designed shapes, the situations that the interiors of the wire pipes are extruded in the bending process, and the pull wire in the wire pipe is extruded and fixed to cause blockage, which is unfavorable for subsequent penetration of wires are effectively prevented, the on-site construction time is effectively reduced, the on-site threading difficulty is reduced, and the problem of threading blockage of the wire pipe during on-site threading is solved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated component production, and in particular relates to a device and method for avoiding line pipe blockage. Background technique [0002] Prefabricated components refer to steel, wood or concrete components that are prefabricated in factories or on site according to design specifications, and the prefabricated components need to be poured into molds during the production process. [0003] Usually, during the preparation and molding process of prefabricated components, wire tubes and wire boxes are buried inside for the later insertion of wires, and the pre-embedding of wire boxes in prefabricated components needs to be pre-embedded according to the drawing design, but the design of the components does not affect the site construction. The threading is not well considered, and the line pipe has many inflection points in the prefabricated components. The steel wire threading cannot be bent in reve...

Problems solved by technology

[0003] Usually, during the preparation and molding process of prefabricated components, wire tubes and wire boxes are buried inside for the later insertion of wires, and the pre-embedding of wire boxes in prefabricated components needs to be pre-embedded according to the drawing design, but the design of the components does not affect the site construction. The threading is not well considered, and the line pipe has many inflection points in the prefabricated components. The steel wire threading cannot be bent in reverse, and the threading is difficult, and it is very easy to cause the line pipe to be blocked when the thread is threaded on site.
