The spatial structure is characterized by the fact that it consists of a support frame (Rn), the lateral edges of which are connected to the settling stabilizing plates (Ps),and four interchangeable measuring panels (P) are mounted on the upper surface,of which each measurement panel (P) contains two beams of support (1) with an upper surface constituting a seat of only three measuring plates (2),and the bottom surface is joined by three separate measuring slats (3), forming a triple measuring system of plate pairs (2 and 3), joined together separately by clamping elements (4),where the individual beams of the superstructure (1) of each measuring panel (P) are connected separately by the thread joints (5) to the superstructure (Rn).
