WATERSTOP PLATE STRUCTURE FOR CONNECTING NEW/OLD CONCRETE AND INSTALLATION SYSTEM

摘要

PURPOSE: An installation system for a waterstop plate structure for connecting new/old concrete is provided to prevent a gap formed by vertical movement by preventing a flow of bleeding from concrete and to intercept underground water after hardening and curing the concrete surface. CONSTITUTION: The installation system for a waterstop plate structure for connecting new/old concrete comprises the steps of forming many spot-shaped projections(120) on the surface/backside of a waterstop plate(100), installing a pair of protective caps(300a,300b) provided with a nail insert groove(310) and an insert groove, then fixing one protective cap to the top of a square bar supporting the waterstop plate(100) and the other protective cap to the bottom of the square bar pressing the waterstop plate(100), fitting the waterstop plate(100) between the protective caps and fixing the protective caps with a stopper(400).
