Prefabricated slab foundation forming die construction method
The invention relates to the field of building construction, in particular to a prefabricated slab foundation forming die construction method. The construction method comprises the following steps that forming die bases with concave longitudinal sections are prepared, and anchoring steel bars are fixed to the lower ends of the forming die bases; after a foundation pit is excavated to the designed elevation, setting out is conducted on a raft foundation; the forming die bases are continuously placed along the side line of the raft, and the anchoring steel bars are inserted at the lower ends of the forming die bases into a bottom soil layer of the foundation pit for fixing; prefabricated slabs are vertically fixed into the forming die bases; concrete is poured on the inner sides of the prefabricated slabs to the upper ends of the forming die bases to form a concrete cushion layer, and soil is backfilled on the outer sides of the prefabricated slabs and tamped; and after the strength and the water content of the concrete cushion meet the requirements, a foundation slab can be constructed for waterproofing. By applying the method, construction is not needed, waterproof construction can be directly carried out, and the construction cost is saved; construction procedures can be reduced, and the construction progress is accelerated; and the construction is simple, and constructors do not need too high performance skills.
本发明涉及建筑施工领域，特别是涉及一种预制板基础胎膜施工方法，包括如下步骤：准备纵截面为凹字型的胎膜底座，胎膜底座的下端固定有锚固钢筋；基坑开挖至设计标高后，对筏板基础进行放线；沿筏板边线，连续放置胎膜底座，将胎膜底座下端的锚固钢筋插入基坑的底部土层进行固定；将预制板垂直固定在胎膜底座中；在预制板的内侧浇注混凝土至胎膜底座的上端形成混凝土垫层，在预制板的外侧回填土并夯实；混凝土垫层的强度及含水率符合要求后即可施工基础底板防水；应用本方法，无需砌筑，能够直接进行防水施工，节约了施工成本；能够减少施工工序，加快了施工进度；施工简单，施工人员无需过高的执业技能。
