摘要

The building has auxiliary panels, each symmetrical to two axis. Each has a flat front and rear part (1). Each side face (2), has two grooves (3), for seals. Between the grooves is a rebate (4) e.g. for batten or strip fitting. The corners (5) are chamfered. A main panel has a partition (8) whose centre line is at a distance (B) w.r.t. the side which are symmetrical to one (X) axis, and have flat front and rear surfaces (1). One side surface (6) is flat. The opposed side surface (7) has two grooves (3) for seals, whilst the four corners (5) are chamfered. Alternative construction may have main panels with two or five partitions.
