A quality-controllable assembled staircase mold and staircase manufacturing method

Abstract

The invention relates to a quality controllable fabricated stair mold and a stair manufacturing method. According to the stair mold, a lower template is fixed on a plurality of vibration platforms; aplurality of ultrasonic detectors for monitoring concrete pouring compactness are mounted on a bottom template; a pouring opening is formed in the horizontal section of the top of a step template, anda plurality of overflow holes are uniformly formed in the step template in the length direction of the step template; a portal frame is straddled on the lower template and can move along a hydrostatic guideway, a cross beam of the portal frame is connected with the step template through a hydraulic stretchable rod, and a notch for a lifting hopper to pass through is arranged at the position, above the pouring opening, of the cross beam; and the whole fabricated stair mold is controlled through a PLC. The fabricated stair mold is high in automation degree, automatic mold closing and demoldingcan be achieved, the production efficiency is high, and meanwhile the labor intensity of workers is reduced. The ultrasonic detector is cooperated with the vibration platforms, so that the compactnessof each position of a pouring member is ensured, the yield is guaranteed, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of construction and relates to a controllable assembled staircase mold and a staircase manufacturing method. Background technique [0002] The prefabricated concrete staircase mold is a product of residential industrialization. Through factory prefabrication and on-site assembly, the construction period is shortened and the cost is reduced. The traditional assembled mold includes two opposite side formworks, a bottom formwork and a step formwork arranged on both sides of the side formwork at relative intervals along the longitudinal direction, and two head plates arranged at the longitudinal opposite ends of the bottom formwork and the step formwork. The mold cavity that forms the stairs. During production, the bottom formwork is laid flat, and a reinforcement cage is placed on it, and then the step formwork is closed, and the entire mold is erected by the spreader. After the mold assembly is completed, the concrete...

AI Technical Summary

Problems solved by technology

Although the disassembly device improves work efficiency to a certain extent and reduces the labor intensity of workers, vertical pouring is not conducive to the compactness of concrete

In addition, the existing prefabricated staircase molds still generally lack effective quality control during the pouring and molding process. Once the quality of the finished staircase lifted out is found to be unqualified, it can only be scrapped, resulting in loss of time cost and economic cost
