Description

Post-pouring strip structure and superimposed sheet Technical Field The application relates to the technical field of assembled buildings, in particular to a post-pouring strip structure and a superimposed sheet. Background The laminated slab is an assembled integral floor slab formed by laminating precast slabs and cast-in-situ concrete layers, before the concrete layers are cast, post-cast strips are required to be reserved at corresponding positions of a foundation slab, walls and beams according to design specification requirements, and the post-cast strips are used for preventing harmful cracks of a cast-in-situ reinforced concrete structure due to uneven self shrinkage or uneven settlement in building construction. In the building construction process, two adjacent precast slabs are often arranged at intervals to form a post-cast strip between the two precast slabs, then a formwork is hung below the post-cast strip, then a scaffold or a stand column is used for supporting the formwork, after the supporting is finished, concrete layers on the precast slabs are poured firstly, then concrete layers on the formwork are poured, and a laminated slab is formed after the pouring is finished. However, the above-mentioned superimposed sheet needs to set up and support the post-cast strip region, is limited by the construction space below the floor, and is liable to cause the condition that formwork is difficult and formwork is long to influence construction period. Disclosure of utility model In view of the above, the application provides a post-cast strip structure and a superimposed sheet, which are used for solving the problems that the construction period is influenced by the fact that the existing post-cast strip region needs to be erected and supported and is limited by the construction space below a floor slab and the formwork is difficult to support and the formwork support time is long. The application provides a post-cast strip structure, comprising: the first precast slab and the second precast slab are arranged at intervals; The truss units are distributed at intervals along a first direction, each truss unit comprises a first lower chord rib, two ends of each first lower chord rib extend into the first precast slab and the second precast slab respectively, and each first lower chord rib is provided with a first rib section positioned between the first precast slab and the second precast slab; The template is connected with at least one first rib section, and the template respectively with first prefabricated plate with the butt of second prefabricated plate, first prefabricated plate the second prefabricated plate and the template enclose and close and form and wait to pour the space. The post-pouring strip has the beneficial effects that the space to be poured is the post-pouring strip, the template is connected with the first rib section, and the template is abutted with the first precast slab and the second precast slab, so that the strip pouring space can be formed by enclosing, and the template is not required to be erected and supported in the post-pouring strip area, so that the time spent on supporting the template is saved, the construction difficulty is reduced, and the construction efficiency is improved. In an alternative embodiment, further comprising at least one connection assembly by which the formwork is detachably connected to one of the first rib sections, the connection assembly comprising: The first mounting piece is provided with a first connecting part and a second connecting part which are connected, the first connecting part is sleeved on the periphery of the first rib section, and the second connecting part penetrates through the template and extends out of the template; And the second mounting piece is detachably connected with the part of the second connecting part extending out of the template. The method has the beneficial effects that after the concrete poured on the template is solidified, the second mounting piece is detached from the second connecting plate outside the template, and then the template is separated from the solidified concrete, so that the template can be detached. On the one hand, the template is separated from the solidified concrete, so that the subsequent construction operation of the solidified concrete, such as the operations of perforating, pipeline installation and the like, is convenient, and on the other hand, the disassembled template can be reused, so that the construction cost is reduced. In an alternative embodiment, each of the truss units further comprises: The upper chord rib spans over the first precast slab and the second precast slab; The first web members are distributed at intervals along a second direction, the second direction is perpendicular to the first direction, each first web member is connected with the upper chord rib and the first lower chord rib respectively, and the upper chord rib, the first lower chord rib and eac
