SUBSTANCE: spatial construction-structure of higher earthquake stability includes rod elements from glass-plastic pipes and nodal joints also from glass-plastic pipes, but of larger diameter. In the upper nodal joints six rod elements are formed, which are arranged from each other at the angle of 60° and are forwarded down relative to the horizontal plane at the angle of 30°.

The lower nodal joint arranged at one axis with the upper one is created in the same manner as the upper one, but it is turned upside down, besides, in the lower nodal joint apart from ascending ones there are another six horizontal rod elements directed towards other lower nodal joints and displaced relative to ascending rod elements by 30° in the plan, which form a lower belt of the spatial construction structure.
