Lintels and corners
The IZODOM technology allows a few methods of making formwork corners
The Izodom technology allows a few methods of making formwork corners. The elements can be joined just like a course of bricks or blocks and an opening should be cut in the wall of one of the adjoining elements to allow the monolithically connection of concrete in the corner. Without the opening, the concrete in two perpendicular walls would not "meet".
Round walls or walls turning at a different angle can be made in rather uncomplicated manner with the MCF 0.7 “hinge” elements which allow to replicate any wall turning angle. The figure below shows the wall with two turns, with an element installed in the bottom course. Such stiffening used before concreting ensures that the planes of both parts of the wall will fit perfectly and there will be no problems to install the doors afterwards.
The Izodom technology does not require a lot of reinforcement because a 15 or 20 cm concrete wall is very strong itself. However, the corners and edges are critical areas and need an additional strengthening.
In the corners, we use vertical reinforcement with two 10 mm dia rebars to strengthen the joint between walls. It is particularly important in case of connection between the gable and the side wall in buildings with pitched roofs. Special oval stirrups made of 5 or 6 mm dia wire are placed in each course of the styrofoam elements
The lintels are made from the U-shaped ML elements. One-metre elements are joined by means of the tongue-and-groove method to obtain the required lintel length.
