Product Description

Vertical Passages in Underground Construction Shaft Stairs

Shaft Stairs In Underground are mainly used for vertical passages in underground construction. Standard components are used and overlapped on site.

Shaft Stairs Passages is customary to use ventilation shafts made of precast concrete parts to provide for room ventilation in multi-storey residential buildings. The elements are storey high and, besides the main draught, Staircase Shaft usually have two inlet lines opening on each floor in the main draught. These Construction Shaft Stairs can be produced vertically in multiple molds, where the cores must be pulled within a certain time window. The disadvantage of this method is the relatively poor surface finish and the poor dimensional stability.
The alternative is to produce the Shaft Stairs Passages in two parts by manufacturing the complex channel part and the cover plate separately. Then the two parts are connected to each other, by welding plates, for example.
A simple solution to this problem is achieved by using a mold which is equipped with foldable side walls, and by producing the cover separately as a flat element.
Both are produced on existing tilting tables, but can also be used on other stationary tables or pallets.
Stairs and ventilation shaft molds, used on tilting tables or in pallet circulation, are an economical solution to produce premium quality standard precast concrete parts for residential building in a flexible manner. Lijian manufactures tailor-made and perfectly adjusted Staircase Shaft formworks and ventilation shafts in accordance with customers` requirements and the needs of the respective market.
