REFRACTORY COATING STRUCTURE OF STEEL BEAM AND REFRACTORY COATING METHOD OF STEEL BEAM

摘要

PROBLEM TO BE SOLVED: To provide a refractory coating structure of the steel beam and a refractory coating method of the steel beam in which a steel beam can easily be coated by a refractory coating material.;SOLUTION: A refractory coating structure 1A of a steel beam is provided in which the steel beam 3 with a deck plate 2 installed in the upper part is coated with a sheet refractory coating material 4. The refractory coating structure has a fixture 5A for fixing the refractory coating material to the deck plate 2. The fixture 5A has: a screw 51 constituted so as to be penetrated from an upper side to the deck plate 2 at the side of the steel beam 3 and capable of being locked to the deck plate 2, and having the refractory coating material 4 constituted so as to be inserted in the lower side of the deck plate 2; and a supporting member 52A formed larger than the diameter of the screw 51, constituted so as to be inserted to the screw 51 in the lower side of the refractory coating material 4 and constituted so as to be locked to the screw 51, and constituted so as to support the refractory coating material 4 from the lower side.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
