A joint for wall panels made of cross laminated timber

A wall panel joint comprising:

• a first wall panel having a front face and a back face, spaced apart from the front face, two side edges, where each side edge extends between the front face and the back face on each respective side of the faces, and a top edge and a bottom edge;
• a second wall panel having two wide faces spaced apart from each other, a first side edge and a second side edge where each side edge extends between the two wide faces on each respective side of the wide faces, and a top edge and a bottom edge;
• wherein the first wall panel in the middle section and on the back face thereof comprises a T-slot,
• wherein the first side edge of the second wall panel comprises an L-type extension,
• wherein the T-slot of the first wall panel is formed so that upon assembly of the first wall panel with the second wall panel, the L-type extension of the second wall panel is received in the T-slot of the first wall panel and a wedge space is formed,
• wherein the wedge space is defined by the L-type extension of the second wall panel and the T-slot of the first wall panel,
• wherein the wall panel joint further comprises two wedges, wherein each wedge is in the form of elongated bar and one side edge of the wedge is inclined so that upon assembly of the first wall panel with the second wall panel both wedges are inserted into the wedge space so that the interference fit is formed between both wedges and both wall panels;
• and
• wherein the first wall panel and the second wall panel are made of cross laminated timber (CLT) panels.
