Abstract

The invention discloses a segmentation method for producing a base plate of a precast concrete laminated board by a long-line pedestal method, belongs to the technical field of construction engineering; a segmentation device is combined with a die-drawing device; when the base plate of the precast concrete laminated board is produced by the long-line pedestal method, an initial end of a first segment, the two ends of a middle segment and the tail end of an ending segment can divide the base plate of the precast concrete laminated board in a heading direction of a drawing die; after a long steel bar is cut off, the exposed steel bar can be reserved at the side of the plate. The bottom plate of the precast concrete laminated board produced by the long-line pedestal method has high productionefficiency, good product quality, and can reduce the production cost greatly.

Description

technical field [0001] The invention belongs to the technical field of construction engineering and relates to a prefabricated concrete structure, in particular to a segmented method for producing a prefabricated concrete laminated slab bottom plate by a long-line pedestal method. Background technique [0002] The preparation method of the concrete laminated slab bottom plate for prefabricated concrete structure buildings is generally adopted at present. The traditional method is to use a small fixed or movable table formwork, support the side formwork on the table formwork, bind all the steel bars, and then pour the concrete, and then remove it after curing. mold. The production efficiency of this method is low, the cost is high, and the appearance quality of manual roughening on the surface is poor, and it is not convenient to apply prestress, and it is easy to crack during production, lifting and installation.
