A wall drain board is provided to prevent the deformation of a base frame in or after construction by improving the structure of a base frame and to cut down on construction expenses by shortening a period of construction and reducing labor costs. The wall drain board comprises a base frame(10), a decorative panel(20) put on the base frame, and a fixing bar fixed with the base frame. The base frame contains a groove(12) provided with a fixing projection(12a) to be fitted to a fixing groove formed on the inside of the decorative panel, a reinforcement truncate part(11) retreated inward not to be bent, a coupling groove stepped along a long circumferential plane of the base frame and composed of a fitting part to fix a coupling bar and a hanging part(13b) to fix a fixing projection(14a) of a coupling bar, a coupling bar(14) slanted against the fitting part of the coupling groove to locate on the hanging part of the coupling groove when another base frame is placed parallel with the pre-constructed base frame, a coupling groove formed on a short circumferential plane of the base frame, a coupling bar(15) formed laterally in the corresponding width to the coupling groove, a supporter(17) provided with a fixing projection(17a) hollowed in the corresponding depth to the thickness of the fixing bar and formed in a C-shape to increase durability against distortion, and a pivot suspension(18) formed in the corresponding length to the fixing projection of the supporter to be placed on the top of the fixing bar. |
