Reinforced concrete floor slab protective layer thickness control device and construction process
The invention discloses a reinforced concrete floor slab protective layer thickness control device and a construction process thereof, and belongs to the technical field of concrete pouring. The device is assembled on a reinforcing mesh for use and comprises a bottom control cushion block and a top control cushion block; the bottom control cushion block is cylindrical and is provided with a central round hole, the bottom control cushion block penetrates through a lower-layer bottom rib of the reinforcing mesh through the round hole, the diameter of the round hole is slightly larger than the outer diameter of the lower-layer bottom rib, and the wall thickness of the cylinder is equal to the thickness of a bottom rib protective layer; and the height of the top control cushion block is equal to the thickness of a floor slab, grooves are formed in the upper end and the lower end of the top control cushion block respectively, the grooves are used for embedding an upper-layer bottom rib and a lower-layer bottom rib of the reinforcing mesh respectively, the width of the grooves is slightly larger than the outer diameter of the reinforcing steel bars, and the depth of the first groove is equal to the sum of the thickness of the protective layer and the outer diameter of the bidirectional reinforcing steel bars. According to the invention, the purpose of accurately and effectively controlling the thickness of the protective layer and the floor slab is achieved, concrete workers can vibrate the cast-in-place floor slab and finish the surface layer, and the process is simple and convenient to operate.
本发明公开了一种钢筋混凝土保护层厚度控制装置及其施工工艺，属于混凝土浇灌技术领域。该装置装配于钢筋网上使用，其包括底部控制垫块和顶部控制垫块；底部控制垫块为圆柱形，具有一中心圆孔，底部控制垫块通过该圆孔穿在钢筋网的下层底筋上，圆孔的直径大小略大于下层底筋的外径大小，圆柱的壁厚等于底筋保护层厚度大小；顶部控制垫块的高度为楼板厚度，其上下两端各开设有凹槽，凹槽分别用于嵌入钢筋网的上层底筋和下层面筋，凹槽的宽度略大于钢筋外径大小，第一凹槽的深度等于保护层厚度与双向钢筋外径大小之和。本发明达到准确有效控制保护层和楼板厚度目的，有利于混凝土工人对现浇楼板振捣和面层收光，且工艺操作简单方便。
