buildings, etc. The present invention power or communication cables for the connection to the related pahyeonggwan as, more particularly, to provide the power and tongsingwan the judoe to sapseol Assembly District, which at the same time, thus simply fixed to the assembly building etc. ; In general, an essential requirement in the buildings and facilities in the industrial society to a high level of technical development power will be referred to the connection and communication at the same time. ; However, the durability of buildings, etc. are installed and buried hayeoseo Ghana since the construction thus increasing installation of karate as well, not just building for each location separately tongsingwan pipes to the disturbing, even if often the case. ; So, as the invention cares to solve the problem as described above, ; convex in the longitudinal direction while the above-described circular cross section a part with grooves, but form an additional length pahyeonggwan formed as arc-shaped in the direction T to both sides, the two sides of the portion in contact with any portion of the convex portion pahyeonggwan fused to each other integrally formed with each other to provide facing grooves hayeoseo invention a fastener, gives to reinforce the stability of the reinforcement in reinforced concrete construction with external pressure from the construction site, and the invention also provides for a stable insertion of wires or communication eda pahyeonggwan of both hayeoseo not fixed by simply fixing hayeoseo using the fasteners on the exterior of buildings , and thus the invention is for the embodiment.
