Electrical threader for building construction

Abstract

The invention relates to an electric wire guider used in construction, which uses several beams of PET plastic wires to form the thick and rigid main guide wire and several beams of stainless steel wire to form thin and soft leading guide wire, and via the middle transition interface, compresses the ends of main guide wire and leading guide wire to connect the guide wire and leading guide wire, and combining with the guide heads at their ends to form said electric wire guider. Since the end of guide head is smooth, the leading guide wire made from stainless steel wire is easily to be bended with better flexibility, and the main guide wire made from PET plastic wire is thick and rigid with better flexibility, it can effectively push and control the motion of leading guide wire and guide head without any additional demand to the guide pipe. In the construction, the plastic ripple pipe with easy bended and lower cost can be used to replace present steel pipe, to reduce the time, cost and steel material.

Description

technical field [0001] The invention relates to a construction auxiliary facility, in particular to an electrical lead-through device for building construction. Background technique [0002] At present, in the construction of buildings, threading wires is the most critical and cumbersome work in electrical engineering. For a long time, it is usually combined with electrical pre-embedded engineering during infrastructure construction, and the traction wire is first inserted into the steel pipe. , Then bend the pipe, and finally pre-buried steel pipes with traction wires according to the requirements of the electrical wiring during the infrastructure construction, so as to guide and pull the wires in the electrical wiring process after the construction of the building infrastructure. Therefore, in the construction of buildings, a large amount of steel will be consumed in the electrical pre-embedded project alone. Moreover, in the process of infrastructure construction, it oft...

Problems solved by technology

Therefore, in the construction of buildings, a large amount of steel will be consumed in the electrical pre-embedded project alone.

Moreover, in the process of infrastructure construction, it often happens that mortar is poured into the steel pipe due to improper construction. If the construction period is a little longer, both the steel pipe and the iron wire in the steel pipe will be corroded, causing the inner surface of the steel pipe and the iron wire surface to be rough. And the thickness of the iron wire is uneven, and the tensile strength is greatly reduced, so that the traction iron wire with the wire tied at the end is pulled through the steel pipe with heavy resistance, and it is easy to cause the traction iron wire to break midway or be stuck. bring difficulty

Once this kind of situation occurs, it is necessary to dig out the cement and open the steel pipe, which not only affects the quality of infrastructure construction, but also consumes a lot of manpower and material resources, and ultimately affects the construction progress, so there are labor, time and material costs. and many other problems, no matter from the economical and practical point of view, it is not ideal
