A panel form comprises a metal sheet with fixation elements. To the metal sheet in rectangular form directed, for instance, by horizontal, in perimeter metal strips are fixed with planes of those oriented normally to the plane of the sheet with formation of a box-like spatial construction. The inner space of the box construction is divided with metal strips to four equal by parameters volumetric spaces each of which is divided into four sections with normal to each other metal strips. In the end section of the box construction through openings are provided, and in the upper and the lower side sections of the box construction pair openings are provided, those are placed one from another at same distances, and divide the side surfaces of the box structure into four sections. |
