Method for constructing a support ring in a curved wall

A method for constructing a support ring in a curved wall;

• the method comprising the steps of:
• (a) providing a plurality of standardized wedge-shaped bricks, the bricks having:
• a front face and an opposite rear face,
• an inner base and an opposite outer base, the inner base being smaller than the outer base and being directed towards a centre of the support ring,
• two side faces for connecting to neighbouring bricks, the side faces being provided with tongue and groove profiles for cooperating with the side faces of the neighbouring bricks,
• an axial direction passing through the front and rear faces, the axial direction being parallel to an axis of the support ring once the plurality of bricks are laid out to form the support ring,
• a radial direction passing through the inner and outer bases, the radial direction being perpendicular to the axis of the support ring once the plurality of bricks are laid out to form the support ring and extending from the centre of the support ring towards the brick,
• a thickness of the brick in the axial direction, the thickness being in excess of a desired end thickness of the brick;
• (b) determining the intended location of each individual brick in the curved wall;
• (c) determining, based on the intended location of an individual brick in the curved wall,
• the location of a front cut line for shaping the front face of the brick, and
• the location of a rear cut line for shaping the rear face of the brick;
• (d) shaping the front and rear faces of the brick in accordance with the above determined front and rear cut lines by means of a cutting tool.
