Abstract

PROBLEM TO BE SOLVED: To ventilate the inside of an outer wall frame by arranging a large number of grooves on both surfaces of a backing plate main body, and arranging the step difference part to communicate with the grooves in the peripheral edge part on both surfaces of the backing plate main body. SOLUTION: The groove part 2 arranged on the obverse/reverse of a backing plate main body 1 is communicated with the step difference part 4 arranged in the obverse/ reverse peripheral edge part 3 of the plate 1. When the plate 1 is used as plywood for an outer wall structure, an air vent continuing by the groove 2 is formed on a contact plane of the plate 1 and an external facing material to the second floor from the first floor, and since the upper end of the plate 1 of the second floor is opened in an attic, an air flow is generated in the groove 2 to ventilate the inside of the external facing material. Next, in an outer wall filled with a heat insulating material, the outer wall inside is ventilated by the air vent formed in the contact plane of the groove 2, an upper frame, a lower frame and a head connector. When the plate 1 is used as a floor structure, since the air vent is formed between the plate 1 and a finishing plate material by the groove 2, ventilation is performed to prevent a warp by moisture and reduction in durability. Therefore, heat entering a house can be cut off in the summer, and dew condensation can be prevented in the winter.
