The present invention provides a ventilation board for drying a slab, the ventilation board comprises: a floor panel disposed on the upper surface of a slab; and a wall panel which is extended from one side of the floor panel, disposed on a wall, and folded by a hinge unit. The floor panel and the wall panel have multiple blocks formed at constant intervals in a longitudinal direction. The block has multiple cups formed therein. The cups have section surfaces provided therebetween, wherein the section surfaces are formed on the position which is lower than the upper surfaces of the panels and higher than the bottom surfaces of the cups. The ventilation board according to the present invention is provided to have a more simplified structure than those of existing ventilation boards, thereby facilitating production and reducing production costs; to facilitate construction, thereby reducing construction period; to be treated in a wet process, thereby removing moisture gathering in the center of the upper surface of the slab; and to form multiple air layers, thereby helping block noises through the floors. |
