Embodiment Construction
[0050] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.
[0051] see Figure 1-Figure 10 , the embodiment of the present invention provides a construction method for reserving the post-pouring belt of the base plate.
[0052] see figure 1 and figure 2 , before construction, it is necessary to prefabricate the canister formwork 100. The canister formwork 100 includes two parallel and spa...

The invention discloses a reserved foundation mat post-cast strip construction method, and belongs to the technical field of building construction. According to the method, a post-cast strip reinforcement layer with two banquettes is cast, the two banquettes are positioned on two sides of the a post-cast strip and can support lower reinforcing steel bars of a foundation mat and prevent concrete from leaking towards the post-cast strip from lower gaps of the lower reinforcing steel bars of the foundation mat when concrete is cast on two sides of the post-cast strip, separation templates are arranged on a water-stop steel plate in a supporting manner and matched with sponge bars and pressing wood blocks, so that gaps of upper reinforcing steel bars of the foundation mat are sealed and plugged, the concrete on two sides of the post-cast strip cannot flow into the post-cast strip from the gaps of the upper reinforcing steel bars of the foundation mat, the overall shape of the post-cast strip is attractive after templates are disassembled, and quality is excellent when the post-cast strip is constructed once.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for reserving a post-pouring belt of a foundation floor. Background technique [0002] In order to adapt to environmental temperature changes, concrete shrinkage, uneven settlement of structures and other factors, the concrete strips with a certain width reserved in the main structures such as beams, slabs, and walls and poured after a certain period of time are called post-casting strips. . [0003] In the existing construction method of reserving the post-casting belt of the base plate, the gap of the protective layer of steel reinforcement in the lower layer of the base plate is closed with a dense mesh steel wire mesh, and the protective layer of steel reinforcement at the top of the bottom plate is also closed with a dense mesh steel wire mesh. [0004] The lower reinforcement protection layer of the bottom slab cannot be sealed tightly w...
