Title:
METHOD OF BUILDING PIERCING PART FOR HEAT INSULATOR COATED COPPER PIPE AND FOLLOW-UP CONTROL CABLE
Document Type and Number:
Japanese Patent JPH0663173
Kind Code:
A
Abstract:
PURPOSE: To provide a fire-resistance forming structure in which a heat-insulator coated steel pipe and a follow-up control cable are simultaneously laid through a through-hole so that the distance of fire-resistant process therefor is shortened.
CONSTITUTION: Steel pipes 1 each coated thereover with heat insulator coating layers 2 which are cut off in part therefrom, and a follow-up control cable 3 are laid through a through hole 6 formed in a partition wall 5, and then gaps defined among the pipes 1 and the cable 3 are filled with a curable fire- resistant filler 4.
