FIREPROOFED AND FRP-REINFORCED COMPOSITE CONCRETE CONSTRUCTION

摘要

Disclosed is a fireproofed and FRP-reinforced composite concrete construction. According to the present invention, the fireproofed and FRP-reinforced composite concrete construction comprises: a concrete construction with a long grove formed in a lengthwise direction of at least one reinforcing surface; an FRP reinforcing material fixed to an inner side of the long groove by the bonding of high fire-resistant epoxy; and a shielding mortar made of a heat resistant material finished at a front surface of the reinforcing surface to which the FRP reinforcing material is fixed such that the FRP reinforcing material can be shielded from external heat. According to the present invention, the fireproofed and FRP-reinforced composite concrete construction is advantageous in that for the concrete construction in which the long groove where the FRP reinforcing material is positioned is integrally formed or the long groove is formed by a post-cutting process, the FRP reinforcing material manufactured in the form of a module is firmly fixed by high fire-resistant epoxy which bonds and fixes the FRP reinforcing material to the inside of the long groove, that thermal blocking for the FRP reinforcing material and the high fire-resistant epoxy is overlapping, and thus, structural stability of concrete can be guaranteed to a certain level even in a high temperature environment, and that it is possible to achieve, at one stroke, versatility in which the concrete construction can be easily applicable due to an optimized structure and minimized configuration, regardless of whether the concrete construction is newly installed or already installed, and workability in which the concrete construction can be easily reinforced and fireproofed only by performing an external operation on the concrete construction without mobilizing large-scale equipment.;COPYRIGHT KIPO 2020
