Extruded polystyrene board anti-floating system in advanced water stop post-cast strip and construction method of extruded polystyrene board anti-floating system
The invention provides an extruded polystyrene board anti-floating system in an advanced water stop post-cast strip and a construction method of the extruded polystyrene board anti-floating system. The anti-floating system comprises an advanced water stop post-cast strip bottom structure cushion layer, a building waterproof layer and longitudinal and transverse steel bars on the left side and the right side of the advanced water stop post-cast strip. A water-stop caulking is arranged between the longitudinal and transverse steel bars, an externally-attached water-stop belt is arranged at the bottom of the water-stop caulking, and an extruded polystyrene board is arranged in the middle of the water-stop caulking; an anti-floating structure is arranged at the upper part of the extruded polystyrene board; the part, higher than the advanced water stop post-cast strip, of the top of the extruded polystyrene board is completely embedded and fixed into a limiting groove of the anti-floating structure, and the anti-floating structure is bound and fixed to the steel bars through binding wires. The anti-floating structure is adopted to restrain the extruded polystyrene board in the water stop caulking, so that the extruded polystyrene board is in close contact with the bottom externally-attached type water stop belt, upward deviation of the water stop belt is prevented, the extruded polystyrene board is not damaged, the water stop effect of advanced water stop is guaranteed, and the water stop effect of advanced water stop is improved. The problem that in a traditional advanced water stop post-cast strip, an extruded polystyrene board floats upwards in the concrete pouring process is solved.
本发明提供一种超前止水后浇带中挤塑聚苯板抗浮体系及其施工方法，抗浮体系包括超前止水后浇带底部结构垫层、建筑防水层、超前止水后浇带左右两侧的纵向与横向钢筋；纵向与横向钢筋中间设有止水嵌缝，止水嵌缝底部设有外贴式止水带，中部设有挤塑聚苯板；挤塑聚苯板上部设有抗浮结构；挤塑聚苯板顶部高出超前止水后浇带的部分完全嵌入固定在抗浮结构的限位凹槽中，抗浮结构通过扎丝与钢筋绑扎固定住。本发明采用抗浮结构对止水嵌缝中的挤塑聚苯板进行约束，使挤塑聚苯板与底部外贴式止水带接触紧密，防止其向上偏移，且对挤塑聚苯板无损伤，保证了超前止水的止水效果，解决了传统的超前止水后浇带中挤塑聚苯板在混凝土浇筑过程中的上浮问题。
