Mechanically shaped dry hard concrete ribbed bottom plate and manufacturing method thereof

Abstract

The invention relates to a building floorslab, in particular to a mechanically shaped dry hard concrete ribbed bottom plate and a manufacturing method thereof. The method comprises the steps of laying rebar meshes and prestressed rebars in extrusion forming molds, and erecting plate rib supporting rebars; stretching the prestressed rebars; feeding dry hard concrete into the extrusion forming molds to be extruded and formed; covering a formed dry hard concrete ribbed bottom plate with a curing membrane to be cured; when the strength of the formed dry hard concrete ribbed bottom plate reaches certain degree, cutting off the prestressed rebars, and reserving beard ribs; and lifting the plate. According to the invention, the mechanically shaped dry hard concrete ribbed bottom plate can be mechanically produced, and is accurate in product quality, short in curing period and low in cost; and the manufacturing method has the characteristics that the production is simple, the size is accurate, the strength is high, the rigidity is high, the self weight is light, the utilization amount of rebars is decreased, the quality is reliable, the transportation is convenient, and the like.

Description

technical field [0001] The invention relates to a building floor, in particular to a mechanically formed dry hard concrete ribbed floor and a manufacturing method thereof. Background technique [0002] In the design and construction of traditional building slabs, cast-in-place concrete slabs are generally used. Since steel bar processing, binding, formwork production and support, concrete pouring and curing molding are all completed on the construction site, the processing site, labor costs, and use of formwork are caused. A large waste is generated, and at the same time, it also pollutes the surrounding environment of the building. [0003] The application of laminated floor slab technology solves this problem. This technology is to transport the bottom slab of the floor slab to the construction site after it is prefabricated in the factory. Pouring concrete forms a prefabricated and cast-in-place laminated floor, so that the prefabricated bottom slab can be used as a form...

AI Technical Summary

Problems solved by technology

[0004] However, the production of precast concrete floor still adopts the traditional technology of wet concrete molding, which is affected by human intervention, making it difficult to guarantee product accuracy and quality. At the same time, there are disadvantages such as long maintenance period, low production efficiency, and high cost.
