Spreading and screeding device for finishing a screed floor, and method therefor

Abstract: The present invention relates to a spreading and screeding device (2) for manufacturing a screed floor, and a method therefor. The device is more particularly suitable for manufacturing a cement screed floor. For this purpose the device according to the invention comprises: - a displaceable frame (4); - a roller (6) connected to the frame for levelling the screed floor; and - a pressing and spreading roller (8), connected to the frame and placed functionally in front of the roller during use, for spreading and pressing screed floor material.

Caisson type washroom water leakage preventing-draining construction method

Abstract: The invention discloses a caisson type washroom water leakage preventing-draining construction method. The method includes using cement mortar to form a screed leveling layer inclined to the wall corner pipe root part, and arcing an internal; coating polyurethane waterproof coating on the leveling layer, and raising by the height of 250 to 350mm along a vertical face; after a water storage text is qualified, forming a water guide hole at the wall corner vent pipe root part to drain the stored water, wrapping a cycle of a stainless steel mesh or fiber mesh outside the water guide hole for preventing the water guide hole from blocking, and using a cement foaming plate to cover a polyurethane waterproof layer as a protective layer; mounting sanitary ware, backfilling slags, and pouring fine concrete below the ground elevation by 45 to 55mm after tamping; coating the polyurethane waterproof coating for the second time after the surface of the fine concrete dries, performing ground surface construction, and performing a second water storage test. A hole is formed at the vertical draining pipe root, even though the bottom of the 'caisson' is provided with stored water, the water can be drained through the hole timely, prevention and drainage can be both considered, and the quality is reliable.
