Description

Assembled floor pouring die with disassembling-free templates Technical field: The utility model relates to the technical field of concrete pouring molds in the building industry, in particular to an assembled floor slab pouring mold with a disassembly-free template. The background technology is as follows: at present, templates are required to be arranged during construction of concrete floor pouring molds, and longitudinal ribs are paved inside the templates. The tensile force of the concrete floor slab after pouring is mainly borne by longitudinal ribs, and the shearing force is mainly borne by concrete. The concrete floor pouring die has the following defects: (1) The support frame or the support is required to be arranged outside the template for improving the rigidity of the system, so that the labor and construction period for arranging the support system are huge. (2) The formwork needs to be installed on site, and the formwork is required to be disassembled after the concrete floor slab is poured, so that not only is the workload on site huge, but also a large amount of construction waste is generated on the construction site, and resource waste is caused. (3) When pouring, longitudinal ribs need to be paved on site, which is time-consuming and labor-consuming. The invention comprises the following steps: In order to solve the technical problems, the utility model provides a concrete floor pouring die which does not need to be provided with a bracket or a support outside a template for improving the rigidity of a system and does not need to be disassembled, thereby reducing labor and construction period and resource waste, and provides an assembled floor pouring die with a disassembly-free template, which is characterized in that, the prefabricated floor slab comprises a template layer on the lower side and a thin-wall steel space structure arranged on the upper side of the template layer, wherein the template layer and the thin-wall steel space structure are assembled in a combined mode, a concrete pouring cavity is formed between the template layer and the thin-wall steel space structure and inside the thin-wall steel space structure, and after concrete is poured in the concrete pouring cavity, the prefabricated floor slab is formed.
