Joints of Rear Wall

The stiffness of the furniture body depends only on the stiffness of immovable component elements of the construction, and the thickness of boards affects it to the greatest degree. Rear wall, usually made from thin fibreboards, chipboards or plywood, improves the stiffness of the furniture piece, taking over the majority of shield loads during operational loads. The strength of the furniture is then

determined by how the board is attached to the body (Fig. 4.72). The most advantageous contructional solution is gluing the board to the groove (Fig. 4.72c), and then, the rear wall acts as an elastic shield that was set on the entire circum­ference. It definitely needs to be avoided to attach the board to the front (Fig. 4.72a), and at such a scheme, the board reflects the load state of the cut shield supported discreetly around the entire circumference.
