Abstract

The invention relates to the technical field of concrete construction, in particular to a construction method for an isolating reserved foundation slab post-cast strip. The method comprises the stepsof (1) plain concrete cushion construction; (2) lattice type stainless steel sheet installation; (3) flexible seam filling body installation; (4) tying of tie bars on the two sides; (5) fixing of vertical stainless steel clips; (6) tying of reinforcing ribs on the lower side of the post-cast strip; (7) quick and easy closing net installation; (8) inflexion type frame plate installation; (9) installation and placement of an inflatable core mold; (10) tying of reinforcement ribs on the upper side of the post-cast strip; (11) longitudinal segment limit plate installation; (12) inflation of the inflatable core mold and pouring of concrete; (13) installing of a screw closure structure and removing of the mold core; and (15) fixing of a top plate pull rod. The construction method for the isolating reserved foundation slab post-cast strip is convenient to construct, the construction efficiency of the advanced back-watering construction of the foundation backing can be improved, and the economic and technical benefits are good.

Description

Technical field [0001] The invention relates to the technical field of concrete construction, and relates to a post-pouring belt and a construction method of a foundation slab, in particular to a construction method for isolating and reserved a post-pouring belt of the foundation slab. Background technique [0002] In recent years, with the development of the construction industry, the application of post-pouring zone construction technology in the construction of high-rise buildings is very frequent. However, traditional post-pouring zone technology will increase the cost of project precipitation, long-term exposure and cracks, leaving hidden engineering safety hazards and affecting the follow-up In order to overcome the above-mentioned shortcomings during the construction process, the post-pouring belt advanced water-stop technology came into being. [0003] At present, a reinforced concrete base plate or guide wall is added at the bottom of the post pouring belt of the foundatio...
