になつてきている。 However, with this method, it is difficult to cope with the remarkable increase in the amount of electric wires and cables in recent years and the strict sealing conditions.As a countermeasure, we have developed a module in which electric wires are inserted into metal tubes in advance and sealed at both ends in the factory. , the wall penetration method of embedding it in the building frame is increasingly being used at construction sites.

るようになつている。 In this wall penetration construction method, a module in which a large number of electric wires are inserted through a tube body and these electric wires are hermetically sealed at both ends of the tube body with an epoxy resin sealant is buried in the building frame on site. It is airtightly and removably attached to the embedding tube. This module is equipped with a pair of internal partition plates each having a through hole for passing electric wires so as to form a gas supply port approximately in the center of the metal tube, and tracer gas is supplied from the gas supply port formed between the internal partition plates. is supplied so that the integrity of the sealing material can be confirmed.

あつた。[Problems in the Background Art] However, in the wall penetration construction method for electric wires and cables with such a configuration, the electric wires are passed through the trays, ducts, and conduit tubes that have penetrated the structure at the conventional site, and the wires are sealed with an epoxy resin sealant. Although the workability and airtightness were significantly improved compared to the sealing method, there was still room for improvement in fire resistance.
