Fibre cement plate and a wall structure having the fibre cement plates

A wall structure comprising:

• an array of vertically or horizontally extending support beams;
• and
• a plurality of fibre cement plates attached to the support beams and engaged with each other, each fibre cement plate having a first and a second vertically oriented edge, a first and a second horizontally oriented edge and an inwards facing and an outwards facing surface,
• wherein
• the first horizontally oriented edge is a bottom edge and is provided with an elongated groove and the second horizontally oriented edge is a top edge and is provided with an elongated projection arranged inside an elongated groove of a bottom edge of an adjacent fibre cement plate,
• in that the first vertically oriented edge is provided with an elongated groove and the second vertically oriented edge is provided with an elongated projection arranged inside an elongated groove of a first vertically oriented edge of an adjacent fibre cement plate, and
• in that a sealant is provided in the elongated groove of the first vertically oriented edge.

A method of forming a wall structure, the method comprising the steps of:

• providing an array of vertically or horizontally extending support beams;
• providing a plurality of fibre cement plates, each fibre cement plate including a top edge provided with an elongated projection, a bottom edge provided with an elongated groove, a first vertically oriented edge provided with an elongated groove, a second vertically oriented edge provided with an elongated projection and a sealant arranged in the elongated groove of the first vertically oriented edge;
• attaching a first fibre cement plate of the plurality of fibre cement plates to at least one of the support beams;
• and
• engaging a second fibre cement plate of the plurality of the fibre cement plates with the first fibre cement plate by aligning a bottom edge of the second fibre cement plate with a bottom edge of the first fibre cement plate and sliding the second fibre plate in a horizontal direction so as to cause an elongated projection of the second vertically oriented edge of the first fibre cement plate or an elongated projection of the second vertically oriented edge of the second fibre cement plate to be inserted into an elongated groove of the first vertically oriented edge of the second fibre cement plate or into an elongated groove of the first vertically oriented edge of the first fibre cement plate respectively and to squeeze the sealant arranged in the elongated groove of the second vertically arranged edge of the second or first fibre cement plate.
