Abstract
This utility model relates to a modular, assembled waterstop box, comprising four unit arc plates. A fixed arc plate is provided on the side of each unit arc plate closest to the wall of the opening. The fixed arc plate is perpendicular to the unit arc plate and fits against the wall. Fixed screws are pre-embedded in the wall, with multiple fixed screws evenly spaced along the circumference of the opening. Fixed holes are provided on the fixed arc plates for the fixed screws to pass through, with each hole corresponding to a fixed screw. After passing through the corresponding fixed hole, a fixed nut is threaded onto the fixed screw, which abuts against the side of the fixed arc plate away from the wall. A mating arc plate is also provided on each unit arc plate, parallel to the fixed arc plates and located away from the wall. The mating arc plate has assembly holes for installing a waterstop curtain and a waterstop flap. Adjacent unit arc plates are connected and fixed together by connecting components. This application facilitates the transportation and handling of the waterstop box, reducing installation difficulty.
