PURPOSE:To improve strength and waterproofness, by a method wherein wood reinforcing members are buried in the outer wall of a casing made of synthetic resin, and forms for supporting a shelf, attached to the interior of the casing, are attached to the respective reinforcing members by means of wood-screws. CONSTITUTION:A casing 1 made of FRP of a semiunderground store house is formed with an upper body 5 and a lower body 3, the upper and lower bodies 5 and 3 are joined together by means of flanges 6 and 7, and wood reinforcing members 2 are buried in the outer wall parts of the bodies 3 and 5. When form bodies 14 for supporting a shelf are attached to the interior of the casing 1, the form body 14 is positioned to a portion, where the reinforcing member 2 is buried, to secure it by means of a wood-screw 15. This provides strength being strong enough to allow endurance against an earth pressure, and prevents invasion of water past the mounting part of the form body 14. |
