FIELD: construction.SUBSTANCE: invention relates to advertising, more specifically - to demonstration plants, where information material is fixed to rotary elements of the structure. A prism of an information element of a demonstration plant has three faces in the form of rectangular plates, on longitudinal edges of which there are marginal teeth, having longer and shorter sides, besides, the longer side is inclined relative to the outer side of the face at the angle 30°. On the inner side the faces have connection facilities, and in the condition, when two faces are connected to each other, between longer sides of the marginal tooth there is a gap formed for fixation of a clip in it. The clip has a central part, two inner and two outer strips, which stretch from the central part, besides, inner strips on the free end are made with marginal teeth, and at the end adjoining the central part they are made with thrust ledges. When the clip is fixed in the gap, thrust ledges rest against edges of faces, marginal teeth of clips are engaged with marginal teeth of faces, and outer surfaces of inner strips are pressed to the longer side of the marginal tooth of faces. At the same time outer strips are arranged relative to each other at the angle of 60° and stretch in parallel to the outer side of faces with formation of a gap between outer strips and faces for insertion of the edge of the advertising message carrier in it.EFFECT: development of a prism of an information element of a demonstration plant, which does not require using hexahedral pipes, components of which occupy a small volume during transportation, and which is suitable for realisation of less labour-intensive technology of replacement of an advertising image at a demonstration plant.8 cl, 9 dwg |
