Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and relates to a device for straightening and bending a wire tube. Background Art

[0002] At present, strong and weak electric wire conduits need to be reserved and embedded in the main construction phase. The wire conduits connected to low- and high-position switches and sockets need to be bent at the junction of the cast-in-place slab and the shear wall and column. The construction workers put the wire conduit bending springs into the wire conduits and bend them manually according to the general position. There are large deviations in the bending size, protective layer thickness and quality. During the decoration and renovation stage, the wire conduits under the beams and on the top of the slabs need to be bent. The construction workers put the wire conduit bending springs into the wire conduits and bend them manually. Some wire conduits are bent and deformed during masonry construction due to inadequate protection of the finished products.
