1. Large-panel construction

means the industrial production of wall and ceiling elements in the concrete plant and is carried out by pouring the concrete in formworks when laying down (horizontal) or standing upright (vertical) (battery moulds, vibration and tilting tables, etc.). The precast concrete elements are transported to the construction site and assembled there. The construction of the partial prefabricated ceilings (filigree floor) saves the slab formwork on site. The installation sockets U86 and U12, for instance, are inserted in the filigree floors. They protrude beyond the ceiling slab and are provided with installation conduits on-site at the construction site. After that, concrete is grouted in until the full height is reached.

2. In-place or heaped concrete construction method are individual installations on site

In doing so, a difference is made between laying (e.g. slab formwork) with only one formwork side and standing formwork with two formwork sides (work formwork with opposing formwork).

Working formwork

Ideal, because the installation of sockets and boxes on the first, already standing formwork (working formwork) can be done easily and fast. After the system has been connected to the conduits and the steel reinforcement has been inserted, the second form (opposing formwork) is put to wall distance. After concrete has been grouted and has cured, the working formwork is removed and with this, the front side of the sockets and boxes is separated. Now the insertion devices (switches and sockets) can be mounted.

Backing formwork

If sockets and boxes are installed opposite the already existing formwork, this is called opposing formwork. For this purpose, first the blank bases are mounted on the working formwork; then, the sockets and boxes are put to wall distance using the support beams. In doing so, the support spar length is always “wall thickness minus 1 cm”, independent which sockets or boxes are used! Only the wall thickness determines the length of the support beams! The necessary stability of the system is achieved by the pressure that is applied by the formwork “moving against it”.

Caution: The residence time of the formwork necessary for curing the concrete must be met!
