DEVICE FOR PREVENTING CRACK OF INDOOR FLOOR PLASTER LAYER

摘要

The present invention relates to a mechanism for preventing cracks in an indoor floor plastering layer, and reducing the stress acting on the indoor floor plastering layer by installing a crack prevention mechanism of a specific structure at a point where stress is concentrated during the construction of the indoor floor plastering layer of a certain building. It is an object of the present invention to provide a mechanism for preventing cracks in the interior floor plastering layer that can prevent arbitrary cracks according to the method. To this end, the crack prevention mechanism of the indoor floor plastering layer according to the present invention is made of a synthetic resin material having a predetermined height with a flat top surface, and both ends of the base portion having a bar of a predetermined length or a hexahedral block shape An extension portion having a plane of an isosceles triangle shape is integrally extended so as to achieve left and right symmetry in the base portion, and a fixing portion having a "Y" shape protruding from the center of the rear bottom of the base portion is formed. There is at least one arc-shaped crack blocking portion protruding to prevent cracking.
