PREFABRICATED STRUCTURE OF CULTURAL-LEISURE SOCIAL PURPOSE Russian patent published in 2009 - IPC E04B1/343 

FIELD: construction.

SUBSTANCE: invention is related to the field of construction, in particular to prefabricated structure of cultural-leisure social purpose. Structure comprises knocked-down load-bearing frame in the form of trusses connected to each other to create three-level closed structure. The frame of the first level is shaped as vessel body having nose and stern parts located on different sides from middle part and formed with vertical trusses. Vertical trusses are arranged with the possibility of connection to detachable base and to composite load-bearing truss with closed upper ends. First-level shelter trusses are fixed to load-bearing truss in radial direction. In nose and stern parts accordingly one and two support masts are installed in the form of trusses connected by trusses to load-bearing trusses. Frame of the second-level is shaped as vessel deck superstructure having round shape in section. Superstructure is formed by vertical trusses arranged with the possibility of connection to detachable base and to composite load-bearing trusses with closed upper ends. Superstructure creates a circle in space, to which second-level shelter trusses are fixed in radial direction with upward slope. Windows are located along the whole perimeter of circle. Third-level frame is arranged in the form of dome having round shape in section. Dome is supported by vertical trusses made with the possibility of connection to detachable base and to composite load-bearing trusses with closed upper ends. These trusses create a circle in space, to which second-level domelike shelter trusses are fixed in radial direction with upward slope. Windows are located along the whole perimeter of circle. Dome top has tent with spire arranged with concave generatrix. The base is located at a distance relative to earth level and rests on supports that are adjustable in height. Similar supports serve as supports for vertical trusses. Levels of the first level from external side are encased with panels with the possibility of dismantling. Part of panels is arranged with door openings and windows. Shelters of the first, second and third levels are made from flexible shell. In nose and stern parts shelter is attached to mast-supports. All connection units are arranged as quick-detachable and represent a pin with transverse hole for installation of connected part in hole for fixation.

EFFECT: higher reliability and strength.
