Description

Adjustable general horizontal die for producing stair components

Technical Field

The utility model belongs to the field of prefabricated building components, and particularly relates to an adjustable universal horizontal die for producing stair components and a production process.

Background

Building systems are currently rapidly evolving nationally. In the prior art, the mould for stair production is generally divided into a vertical type mould and a horizontal type mould, and the two moulds have advantages and disadvantages respectively; the cost of the vertical stair is relatively low, the wrapping area of the components is large, and the workload of manual trowelling is small; the horizontal stair structure is relatively heavy, the whole back of the stair needs to be manually trowelled, and the workload is large. The vertical stair is easy to twist, skew, mold expansion and other quality problems of the produced stair components due to the mold structure, and the horizontal stair mold cannot twist the components. The vertical stair mold is only suitable for the production of residential few-step stairs, and the multi-step widened public building stairs are suitable for the production by using the horizontal mold.

The current problems are: 1. the public building stairway with multiple steps is often more in variety and less in quantity, if each stairway is required to be opened in a conventional production mode, the production components of a single stairway mold are too few, the service life of the mold is not exerted, and the cost of the stairway component unit mold is too high; 2. the common practice of reducing the cost of the mould at the present stage is to recycle part of the parts of the lower line mould, but the proportion and the practical type are limited, and the stepping part with a large proportion of the weight of the stair mould is not recycled all the time; 3. the conventional stair mold is of an integral welding structure, a part of the conventional stair mold is deformed or damaged, and the whole mold cannot be used. In addition, for the multi-step lengthened stair component, in the conventional production process, as the contact surface of the steps and the die is too many, and the die is integrally welded, the structural rigidity is high, the adsorption force between the component and the die surface is easily caused to be too large, the demolding is difficult, and the component needs to be knocked to be separated from the die surface, so that the service life of the die is further reduced.
