Abstract
Description
457 549 1 Taket består av stâïpïât (1), uppïagt deïs på ett övre upplag av bärande u-balkar (2) som upphängts i bergförankrade stag (3), deïs på ett nedre uppïag av u-baïkar (4). Den nedre u-balken tjänstgör även som hängränna för Iäckagevatten. Från hängrännan avïeds vattnet via stuprör tiTI lämp- lig pïats i bergrummet. Där avståndet mellan bergtaket øch undertaket medger minst kryputrymme förses konstruktionen med gângbrygga (5) fast- nitad på takpïàtens översida. Bergínspektioner kan då ske från denna brygga. 457 549 1 The roof consists of a stand (1), suspended on an upper layer of load-bearing sub-beams (2) suspended in rock-anchored struts (3), suspended on a lower surface of sub-beams (4). The lower sub-beam also serves as a gutter for leakage water. From the gutter, the water is drained via a downpipe to a suitable place in the rock chamber. Where the distance between the rock roof and the sub-roof allows at least crawl space, the construction is provided with a walkway (5) riveted to the upper side of the roof tile. Bergins inspections can then take place from this bridge.
I bergrum med risk för uppkonmande tryckvâgor pga t ex expïosíon (t ex i kraftstatíoner), förankras takpïàtarna tíïï u-baïkarna med kätting- och brandkârshakar.In rock chambers with a risk of impending pressure waves due to, for example, exposure (eg in power stations), the roof piers are anchored to the u-baïkarna with chain and fire hook hooks.
