Adjustable universal horizontal mold for producing stair components and production process

Abstract

The invention discloses an adjustable universal horizontal mold for producing stair components and a production process, and belongs to the field of prefabricated building components. The adjustable universal horizontal mold comprises a base, a plurality of step units with adjustable inclination angles are sequentially arranged on the base, sizing molds are arranged corresponding to the step units, and each sizing mold comprises two step side edge molds; upper halfpace side edge molds are correspondingly arranged on the left side and the right side of the upper halfpace mold, lower halfpace side edge molds are correspondingly arranged on the left side and the right side of the lower halfpace mold, and a first halfpace end head blocking mold and a second halfpace end head blocking mold are correspondingly arranged on the outer sides of the two upper halfpace side edge molds and the outer sides of the two lower halfpace side edge molds respectively. According to the production process disclosed by the invention, through a combined universal horizontal mold with step units combined and bases reinforced, small-batch multi-variety stair components can be flexibly produced, so that the purchase quantity of the mold is reduced as much as possible, the service life of the mold is developed to the greatest extent, and the stair production cost is saved.

Description

technical field [0001] The invention belongs to the field of prefabricated building components, in particular to an adjustable universal horizontal mold for producing stair components and a production process. Background technique [0002] The prefabricated building system is currently developing rapidly across the country. In the prior art, the molds used for stair production are generally divided into vertical and horizontal types, both of which have advantages and disadvantages; the cost of vertical stairs is relatively low, the area for wrapping components is large, and the workload of manual smoothing is small; The horizontal stair structure is relatively bulky, and the overall back of the stair needs to be manually smoothed, which requires a lot of work. Due to the structure of the mold, the vertical stairs are prone to quality problems such as twisting, skewing, and mold expansion, while the horizontal stairs molds will not have the phenomenon of component twisting. ...

Problems solved by technology

[0003] The current problems are: 1. There are often many types of public building stairs with multiple steps, and the number of each type is small. If it is necessary to open molds for each type of staircase according to the conventional production method, there will be too few production components for a single staircase mold, and the mold itself will not be used. 2. The usual way to reduce the cost of molds at this stage is to recycle some parts of off-line molds, but the proportion and practical types are limited, and the weight ratio of staircase molds is very high. The large step part has not been recycled; 3. Because the conventional staircase mold is an integral welded structure, if a part of it is deformed or damaged, the whole set of molds cannot be used

And for the multi-step lengthened staircase components, in the conventional production process, due to too many contact surfaces between the steps and the mold, and the mold is integrally welded, the structural rigidity is high, and the adsorption force between the component and the mold surface is too large, and demoulding is difficult. It needs to be knocked and hammered to make it break away, which further reduces the life of the mold
