The present invention aims to effectively prevent harmful gas, bad smell, and pathogens or the like, which are generated from manure stored in slurry pit in a cattle shed including the slurry fit installed therein, from flowing back through a manure discharging hole of a floor material. A device for preventing backflow of harmful gas for a cattle shed floor material includes: a plurality of support bars (100) which are arranged at intervals to be placed apart from each other in parallel; a coating plate (101) formed by arranging the support bars (100) in the middle thereof and attaching the support bars in the vertical direction; an incised part (102) that forms an incision line in parallel with a middle portion of the support bar (100), and has one end portion, which is not cut, and the other end portion, which is completely cut; and a joining part (103) which the uncut end portion of the incision part. According to the present invention, each elastic support bar (100) is incised from the coating plate (101) and can be independently bent and recovered. Therefore, the device can prevent discharge of manure and backflow of harmful gas more effectively. |
