BUILDING Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: this relates to construction of industrial ground surface buildings in zones of probable explosions at breakdowns and catastrophes. Enhanced stability of building to external explosions and better protection of people from injuries by structural fragments and glazing can be achieved by provision of threelayer covering along covering beams in middle spans. Lower layer of threelayer covering is made up of covering panels of angular profile, upper layer is made of angular inserts of covering filled with light-weight concrete, middle layer is made of strata of pliable material. In extreme spans covering is made of three layers and inclined with interruptions in longitudinal direction and with lower layer of inclined panels with angular profile. Upper layer is of inclined angular inserts filled with light-weight concrete, and middle layer is of pliable material strata. Installed in interruptions of inclined covering of extreme spans are wall panels of angular profile for skylights, and resting on them with one end are covering panels of angular profile for skylights and with other end on covering beams. Side surfaces of skylights are covered by additional inclined angular inserts filled with light-weight concrete and also by triangle frames with glazing. EFFECT: high efficiency. 4 dwg
