UNIVERSAL PLASTIC PANEL (VERSIONS) Russian patent published in 2014 - IPC E04F13/08 A47F5/08 

FIELD: construction.

SUBSTANCE: method is realised by facilities of development of several versions of a universal plastic panel, which is made of at least one section shaped from at least two plates of preferably rectangular shape so that a pair of plates is located one under the other, to create a volume section, and also to ensure strength, the space between the pair of plates arranged one under the other is filled with cells of preferably rectangular shape, the quantity and size of which is selected randomly or depending on parameters of plates, for connection of sections between each other there is a lock element, formed by ends of parallel plates of the section extended in the place of formation of the lock element for the width of the lock element and bent towards each other to produce two elastically compressible and releasing arched structures arranged at the end of the section along its long side and providing for reliable fixation with the round ledge formed at the opposite side of the section from the lock element at the end of the section along its long side by the fact that the lock element of one section, gripping and holding by means of compression the round ledge of the other section, fixes the sections in the fixed condition relative to each other, providing for reliable connection of sections to each other to produce a collapsible structure made of several sections. To provide for decorative properties and to observe visual homogeneity of the structure made of one or several sections, on that side of the section, where there is a round ledge, there is a slot shaped along the lower side of the slot as extension of the lower plate of the section along the width through its entire length and lateral sides formed at one side by the end of the section and at the other side bent preferably at the right angle by the side of the lower plate, forming a rectangle with an open external side, in this case the round ledge is arranged not in the end of the section, but on the external free side of the slot, in case of combination of several sections into one by means of their arrangement on a single lower plate, the slot between sections is made without a round ledge. The round ledge is made on the external side of the slot, arranged at the external side of combined sections, to eliminate sagging of sections as they are connected or to eliminate sagging of combined sections, the lower side of the slot is strengthened with an additional base. To provide for installation of various holders, and/or decorative retained elements, and/or storage systems on the structure from sections, on one of slot sides there is a closed contour representing a structure of rectangular shape directed along the long side of the section, with width by size smaller than the side wall of the slot, providing for rigidity of fixation of sections along their long side, and also providing for stiffness of fixation of holders, and/or decorative retained elements, and/or storage systems, which by means of their installation into the slot are reliably fixed by means of engagement to the closed contour.

EFFECT: development of such universal plastic panel, design of which would provide for production of finished universal panels of different size and configuration, where reliable fixtures would be provided, design of which would provide for the possibility to create various decorative walls for interiors and exteriors, using universal plastic panels.
