<P>PROBLEM TO BE SOLVED: To provide a ditch lid having a protrusive streak made of a resin on a back face to prevent rattling of the lid with enhanced elasticity of the protrusive streak, which simplifies an operation to attach a reinforcement spacer to a steel bar. <P>SOLUTION: A reinforcement spacer for a ditch lid comprising a rod-shaped, protrusive forming part to form a protrusive streak on a bottom face of the ditch lid; an anchor part that is arranged on top of the protrusive forming part and to be embedded in concrete of the ditch lid; a plurality of rod-shaped spacer parts which are erected from the anchor part and/or the protrusive forming part toward an upper surface of the ditch lid, with top faces thereof to be exposed to the upper surface of the ditch lid; and a plurality of reinforcement support parts to support ends of reinforcing-bars in the ditch lid, is integrally molded from a resin. At least the lower end of the protrusive forming part has a curved surface with an arcuate cross section. The protrusive forming part forms the protrusive streak made of a resin on the bottom face of the ditch lid to prevent rattling with enhanced elasticity of the resin. Both ends of the reinforcing-bar in width direction are fitted in the reinforcing-bar support parts, so that the reinforcement spacer can be easily attached to the reinforcing-bar. <P>COPYRIGHT: (C)2012,JPO&INPIT |
