Description

Post-pouring strip concrete template structure Technical Field The utility model relates to the technical field of building templates, in particular to a post-pouring strip concrete template structure. Background The down-pass construction is a complex systematic engineering requiring a large number of templates in the construction of the main structure. The construction flow of the lower through channel has a time node requirement. In the prior art, after the last section of construction of two adjacent sections of main structures of a lower through channel is finished, the formwork supporting work of a post-cast strip can be carried out after waiting for 28 days, the post-cast strip construction is allowed to be carried out after the top plate concrete is poured for 45 days, the post-cast strip is maintained until the design strength requirement is met after the post-cast strip concrete is poured, and then the construction of an outer wall waterproof layer and the backfilling construction are sequentially carried out. The existing exterior wall template can be removed after the concrete inside the exterior wall template is hardened to reach the design strength, and the exterior wall waterproof layer construction and backfilling construction cannot be performed during the concrete hardening, so that the post-pouring strip construction efficiency is lower. Disclosure of utility model The present utility model aims to solve at least one of the technical problems in the related art to a certain extent. Therefore, the utility model aims to provide a post-pouring belt concrete template structure which can accelerate the backfilling progress of a building and improve the construction efficiency of the post-pouring belt. In order to achieve the above purpose, the present utility model provides a post-cast strip concrete form structure, comprising: prefabricating reinforced concrete templates; One end of each screw is connected with the same surface of the prefabricated reinforced concrete template, and the other end of each screw is used for penetrating through the conventional template; And the water stopping sheet is arranged in the middle of the screw rod. According to the post-pouring strip concrete template structure, the prefabricated reinforced concrete templates are arranged, the plurality of screw rods are connected to the same surface of the prefabricated reinforced concrete templates, the prefabricated reinforced concrete templates can be prefabricated and completed, the site construction time is shortened, after the post-pouring strip concrete pouring is completed, the prefabricated reinforced concrete templates can be subjected to subsequent outer wall waterproof layer construction and backfilling construction without dismantling, namely, the node time of the backfilling procedure is shortened, a large amount of construction periods are saved, and the efficiency of post-pouring strip construction is improved.
