Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction tools, especially relates to a building embedded pipe arc angle processing device. BACKGROUND

[0002] The building embedded wire pipe refers to the pipe system for guiding and protecting electric wire and cable, which is set in advance during the construction of the building and is mainly buried in concrete. The embedded wire pipe is mainly composed of plastic and steel pipe and the like. Its function is to put the wire in the wire pipe in advance for guiding the electric cable into the wire pipe in the later period, so as to ensure the safe laying and convenient maintenance of the electric wire and cable. The electric wire and cable is arranged according to the right-angle turning of the building structure, so the embedded wire pipe also needs to be turned. However, the embedded wire pipe is in a straight line state when it is delivered from the factory. The turning angle needs to be temporarily processed according to the characteristics of the wire arrangement during the construction. At present, the turning angle is usually processed by using a turning angle device. During the use, the embedded pipe needs to be turned by hands and feet, which is laborious. In addition, the excessive friction during the turning process will cause the surface of the pipe to be abraded, and even the pipe will be crushed, which is not conducive to ensuring the construction quality of the embedded wire pipe and needs to be improved.
