HOW REDBLOC PREFABRICATION IS PRODUCED

The plan drawn from architects by means of CAD systems is translated to the corresponding module and then transferred to the robot in the production hall. The solid and ground building stones are lifted from a funicular with a fork lift. The whole and half stones are lifted by a gripper onto a conveyor belt. From this transport belt the actual production is fed with the exact layers and groupings of the wall elements taken over.


In the middle of the production line is the gluing application machine consisting of a two-component adhesive. The application of the adhesive is done according to a patented process. Before the adhesive is applied dust is cleaned from the upper layer of the brick or block. A layer gripper places the layer onto the circulating pallet. During the transfer the bottom of the stone is also cleaned. As soon as the planned height is reached (max. 3.5 m) the pallet is changed.


The adhesive hardening process requires 20 min. until completion. Afterwards the pallets are transferred by means of a traverser and led to the high-tech water jet cutting machine, which tailor cuts windows, electrical outings and the actual wall ending. All outings taken into consideration in the planning are cut out of the prefabricated element. An integrated lentil reduces heat loss and saves time and costs from omitting intensive stem work.


The cutting equipment consists of a high pressure water jet which cut the walls from both sides within millimeters exactly at a maximum of 4000 bar pressure. The used water ends up in a container that collects sludge, silt and the used abrasive (granite sand).


Finally, the cut pieces are lifted out and disposed of. The cut wall elements are lifted with an overhead crane, numbered and placed on container pallets which can be directly transported to the construction site. The transportation requires a 20 ton forklift or overhead crane.
