FIELD: construction. ^ SUBSTANCE: fire-resistant belt, mostly, for building with autonomous (not connected to external walls) floor slabs consists of at least two fire-resistant panels or boards and at least one profile-fixator of specified panels or slabs position made of hardly-flammable composite material on the basis of fibrous reinforcing material and polymer binder, having U-shaped cross section, made of base and shelves, arranged with the possibility of its connection to adjacent similar profile-fixator. Each profile-fixator is arranged with the possibility of horizontal fixation of its base at internal surface of external wall of building, at the same time two or more profiles-fixators are arranged serially relative to each other butt-joined by ends, fire-resistant panels or boards are joined to each other to form flooring, one side of which is intended for free resting at floor slab, and the other one, opposite to specified side, having additional fire-resistant coating, is arranged with gap between shelves of one or several profiles-fixators joined to each other, besides, when other side of flooring is placed between joined profiles-fixators, mutual matching of panels or boards joints in flooring with joints of profiles-fixators is eliminated, at the same time additional fire-resistant coating of other side of flooring is made of material capable of coking with increased volume sufficient to fill specified gap. ^ EFFECT: developing fire-resistant belt simple in design and cheaper in manufacturing, increased fire safety of buildings. ^ 7 cl, 3 dwg |
