Shell construction with the WMT

Wall production process

For wall production, the “toaster” requires a floor area of approx. 150m² plus space for office and crew containers. Area for office and crew containers.

The entire production process incl. Assembly and disassembly can be realized by three workers plus a crane operator.

• Foundation concreting
• Assambly: 3 days (WMT M7)
• Set-up (formwork, wall thickness, etc.) for 10 walls: 8-10 hours
• Concreting: 3 hours
• Drying time: depending on outside temperature and/or optional heater
• Pulling walls: 3 – 3.5 hours
• Disassembly: 3 days (WMT M7)

Process of the shell construction

Due to the prefabrication of the concrete walls on site, up to 12 walls per day can be installed by 3 employees plus 1 crane driver*.

• Preparation of the settling place for the prefabricated wall by means of a mortar relining or rim stones.
• Picking up the wall to be installed by the construction crane
• Lifting the finished wall from the WMT
• Setting down the wall at the intended position
• Aligning the wall with the position
• Securing the wall with two support columns
• Connecting the wall with the previously installed prefabricated wall

How many trucks are needed to transport the WMT?

The mobile wall module toaster can be transported with five truck loads (WMT M7), the larger M8 has six loads.

What is the energy requirement during the toasting process?

Since the toaster is operated purely mechanically, no energy is required other than a few machine tools (impact wrench, binding machine, internal vibrator).
