Device for manufacturing vertical or diagonal concrete components on site

摘要

The concrete is injected into the formwork by a pump. It is injected under pressure through one or more openings (I) in one or more of the walls (B, A) of the formwork at a height which can be reached by an operator working on scaffolding or on the ground. The concrete may be injected through the main wall running lengthwise (B), alternatively it can be injected through the end wall (A). There are one or more injection points (I) placed preferably at less than 60 cm from the base of the formwork. The concrete is injected either with the tube pointing towards the top of the formwork or diagonally to the side. The wall (B, A) with the injection point has a device to attach the injection tube (P). It has a valve (W) which seals the injection point after the concrete has been injected.
