Abstract

The roof structure is also formed to accommodate and conduct away water which leaks downwards from the rock and soil above the underground chamber. Its facility to be dismantled permits the rock surface of the chamber to be inspected.

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.

Claims (3)

1. 3 457 549 PATENTKRAV 1 Demonterbart innertak av korrugerad plåt i bergrum, kännetecknat av att pïåtarna (1) stöder vid sin ena ände mot en i bergrummet högt beïägen balk (2), som är upphängd i ett bergförankrat stag (3) och vid sin andra ände mot en ïägre än baïken (2) beïägen U-balk (4), vänd så att denna komner att fungera som hängränna, varvid pïåtarna är löst anordnade på baïkarna (2 och 4) så att reffïornas riktning är vinkeïrät mot baïkarna (2 och 4).3. 457 549 CLAIMS 1 Removable corrugated iron ceiling in rock chamber, characterized in that the piers (1) abut at one end against a beam (2) located high in the rock chamber, which is suspended in a rock-anchored strut (3) and at its other end towards a U-beam (4) located further than the baïken (2), turn so that it will act as a gutter, the plates being loosely arranged on the baïkar (2 and 4) so that the direction of the refs is perpendicular to the baïkar ( 2 and 4). 2. Demonterbart innertak enligt krav 1, kännetecknat av att U-baïkar (4) är anordnade på båda sidor om och paraïleïlt med baïken (2).Removable ceiling according to Claim 1, characterized in that U-beams (4) are arranged on both sides of and parallel to the beam (2). 3. Demonterbart innertak eniigt något av föregående patentkrav, känne- tecknat av att pïâtarna (1) på sin översida är försedda med en vin- keïrätt mot reffïorna gående inspektionsbrygga (5).Removable ceiling according to one of the preceding claims, characterized in that the piers (1) are provided on their upper side with an inspection bridge (5) running perpendicular to the refs.
