Connection recess tube
The connection recess tube is used for creating a recess in the concrete slab, this enables the precasted walls to be connected to other members in the building.
The tubes are adapted to a standard slab thickness of 150mm. Where thicker slabs are necessary, the tube is paired with an extension. The extension increases the possible thickness up to 250mm. The connection recess tubes are available in two standard lengths – 300 & 400mm. Both lengths are availbale in two different versions:
Standard version with all components made of plastic. Needs to be reinforced with “S-stirrup” and “J-stirrups” according to detail 5.2.
Installation
The standard version is assembled with 2 pcs of S-Stirrups Ø8×500 alongside the tube, see green color in figure 5.2. It is also assembled with 2 pcs of J-stirrups Ø12x850mm around the lower part of the tube, see purple color in figure 5.2. The width of the S-stirrups should be chosen so that it corresponds to the distance between the reinforcement meshes.
