A FIRE RESISTANCE TEST MECHANISM PROVIDING SYMMETRIC BOUNDARY CONDITIONS

摘要

The present invention relates to a fire resistance test mechanism (1), which enables to produce only a symmetric quarter section of a full-size structure and to test it in a fire furnace by means of a connection mechanism providing symmetric boundary conditions, basically characterized by at least one support beam (4) which is in the form of a flat plate and is connected such that it will be perpendicular to the parallel flanges of the rail profile (3), at least one linear bearing system (5) which can move on the rail profile (3), at least one main profile (51) which is in the form of an I-profile and is positioned between the support beam (4) and the rail profile (3), at least one first pin support side plate (52) which is in the form of a flat plate and which is connected onto the parallel sides, i.e. flanges, of the I-profile shaped main profile (51) such that it is perpendicular to the flanges, at least one second pin support side plate (53) which is arranged on the profile body located in the center of the main profile (51) such that it will be parallel and opposite to the first pin support side plate (52), at least one pin (54) which passes through the holes drilled concentrically on the first pin support side plate (52) and the second pin support side plate (53), at least one cylinder (55), which is in the form of a wheel through the center of which the pin (54) passes, and whose outer surface contacts the support beam (4), at least one connecting piece (58) which is in the form of a C-profile and is horizontally connected onto the parallel side of the main profile (51), and in the inner part of C-profile of which the edges of the concrete slab (B) are placed.
