Description
Foreliggende oppfinnelse angår en tak- eller veggmontert trykkavlastninganordning ifølge kravinnledningen. The present invention relates to a ceiling or wall-mounted pressure relief device according to the preamble.
Takmonterte trykkavlastningspaneler har, slik tilfellet også er for veggmonterte trykkavlastningspaneler, som formål hurtig og effektivt å utlufte hurtig økende indre overtrykk til atmosfæren, især slik tilfellet eksempelvis er ved eksplosjoner. I en slik sammenheng utgjør panelene som sådan en vegg eller et tak før<*> de aktiveres og åpnes av overtrykket. Ceiling-mounted pressure relief panels have, as is also the case for wall-mounted pressure relief panels, the purpose of quickly and efficiently venting rapidly increasing internal excess pressure to the atmosphere, especially as is the case, for example, in explosions. In such a context, the panels as such constitute a wall or a roof before<*> they are activated and opened by the overpressure.
Ved vegg- og takmontering av slike paneler foreligger imidlertid fare for at tyngre gjenstander som faller ned mot taket hhv veggen og især panelene, vil ødelegge disse og skade innenfor eller under liggende fasiliteter. When installing such panels on the wall and ceiling, however, there is a risk that heavier objects falling onto the ceiling or the wall and especially the panels will destroy them and cause damage within or below the lying facilities.
Foreliggende oppfinnelse sikrer at fallende gjenstander fanges opp av trykkavlastningsanordningen. The present invention ensures that falling objects are caught by the pressure relief device.
De foran beskrevne fordeler oppnås med trykkavlastningsanordningen ifølge foreliggende oppfinnelse, slik den er definert med de i kravene anførte trekk. The advantages described above are achieved with the pressure relief device according to the present invention, as defined by the features listed in the claims.
På tegningen viser figur 1 skjematisk et vertikalsnitt av et trykkavlastningspanel ifølge foreliggende oppfinnelse hvor figurdelene 1A-D viser panelets oppførsel på grunnlag av en plutselig trykkøkning under panelene, figur 2A-E viser på tilsvarende måte panelets oppførsel når en tyngre gjenstand faller mot panelet og figur 3 viser forstørret og skjematisk en lem i sin normale stilling i anlegg mot panelet. In the drawing, figure 1 schematically shows a vertical section of a pressure relief panel according to the present invention where figure parts 1A-D show the behavior of the panel on the basis of a sudden pressure increase under the panels, figure 2A-E similarly shows the behavior of the panel when a heavier object falls against the panel and figure 3 shows an enlarged and schematic view of a limb in its normal position in contact with the panel.
Som vist i figur IA består avlastningspanelet i prinsipp av i tak eller vegg innlagte felt med panel 2 som svinges dersom det oppstår en plutselig økning av trykket på den annen side, slik tilfellet vil være ved en eksplosjon. As shown in figure IA, the relief panel consists in principle of fields embedded in the ceiling or wall with panel 2 which swings if there is a sudden increase in pressure on the other side, as would be the case in an explosion.
Slike paneler benyttes imidlertid hyppig på steder hvor det foreligger fare for at gjenstander faller ned mot panelene og da slike gjenstander i mange tilfeller er meget tunge, ville de eventuelt kunne trenge gjennom selve panelene 2 og skade innenfor eller under liggende fasiliteter. However, such panels are frequently used in places where there is a risk of objects falling onto the panels and as such objects are in many cases very heavy, they could possibly penetrate the panels themselves 2 and cause damage within or below lying facilities.
For å unngå dette er det under panelene 2 anordnet flere etter hverandre anordnede lemmer 1 som ligger an mot panelenes 2 andre side. Lemmenes øvre kanter vil følge eventuelle bevegelser i panelene 2 og stiller seg i det vesentlige parallelt med panelene 2 når disse er svingt så mye ut at de gir overtrykket fri passasje forbi lemmene 1, slik det er vist i figur ID. Lemmene 1 er dreibare om en hengsel 5 og panelene 2 er dreibare om en hengsel 7. In order to avoid this, several successively arranged limbs 1 are arranged under the panels 2, which rest against the other side of the panels 2. The upper edges of the limbs will follow any movements in the panels 2 and stand essentially parallel to the panels 2 when these are swung out so much that they give the excess pressure free passage past the limbs 1, as shown in figure ID. The limbs 1 are rotatable about a hinge 5 and the panels 2 are rotatable about a hinge 7.
Figur 2A viser et tilfelle hvor en gjenstand 4 faller ned mot et panel 2 og hvor lemmer 1 ligger an mot panelenes 2 undersider. Figure 2A shows a case where an object 4 falls against a panel 2 and where limbs 1 rest against the undersides of the panels 2.
Når en gjenstand 4 treffer et panel 2 vil dette bøyes og de underliggende lemmer 1 presses nedover i de tilfeller panelerTe 2 er montert horisontalt, og de innenfor liggende lemmer 1 vil presses inn i de tilfeller panelene 2 er montert vertikalt. When an object 4 hits a panel 2, it will bend and the underlying members 1 will be pressed downwards in the cases where the panels 2 are mounted horizontally, and the internal members 1 will be pressed in when the panels 2 are mounted vertically.
Figur 2D og E viser videre hvorledes gjenstanden 4 fanges opp av panelet 2 og de underliggende lemmer 1. Panelene 2 og lemmene 1 fanger således opp gjenstandens 4 potensielle energi og stopper gjenstandens bevegelse. Figures 2D and E further show how the object 4 is captured by the panel 2 and the underlying limbs 1. The panels 2 and the limbs 1 thus capture the potential energy of the object 4 and stop the object's movement.
Formålet med foreliggende oppfinnelse er å fange opp og stanse fallende gjenstander 4 og derved hindre skader på underliggende eller innenfor liggende utstyr. Penetrering av panelene 2 og til og med lemmene 1 aksepteres dersom ikke underliggende, hhv innenfor liggende utstyr skades. I prinsipp kan trykkavlastningsanordningen ifølge oppfinnelsen benyttes for trykkavlastning i horisontal stilling, dvs som gulv eller tak og også i vertikal stilling som vegg. The purpose of the present invention is to catch and stop falling objects 4 and thereby prevent damage to underlying or internal equipment. Penetration of the panels 2 and even the limbs 1 is accepted if no underlying, or within lying equipment is damaged. In principle, the pressure relief device according to the invention can be used for pressure relief in a horizontal position, ie as a floor or ceiling and also in a vertical position as a wall.
Vesentlig er at fallende gjenstanders 4 energi oppfan-ges for å stanse gjenstandene. Hertil benyttes mot lemmenes under- eller innside anliggende vinkelbraketter 6. Ved påvi.rkning av fallende gjenstander 4 slår lemmene 1 mot vinkelbrakettene 6 som sammen med lemmene 1 opptar energien ved at de deformeres eller knekker. Dette er vist på figur 4 som viser en forstørrelse av figur 2E. It is essential that falling objects' 4 energy is captured in order to stop the objects. For this, angle brackets 6 are used against the underside or inside of the limbs. When impacted by falling objects 4, the limbs 1 strike the angle brackets 6, which together with the limbs 1 absorb the energy by being deformed or broken. This is shown in figure 4 which shows an enlargement of figure 2E.
