Description
Oppfinnelsen angår en korrosjonsbeskyttelse for et festeelement med en ekspansjonshylse og en bolt som kan forankres i et murverk, og som har et parti som rager utenfor murverket og tjener til å holde kledningsplaten, underkonstruksjonen e.l. på avstand fra veggen, samtidig som der rundt det forlengede parti av bolten er satt inn en slangelignende, av elastisk ettergivende plast bestående beskyttelseshylse som kan trykkes sammen i lengderetningen og fullstendig omgir det forlengede parti. The invention relates to a corrosion protection for a fastening element with an expansion sleeve and a bolt which can be anchored in a brickwork, and which has a part which projects outside the brickwork and serves to hold the cladding plate, the substructure etc. at a distance from the wall, at the same time that around the extended part of the bolt a snake-like protective sleeve consisting of elastically yielding plastic is inserted which can be pressed together in the longitudinal direction and completely surrounds the extended part.
Denne anordning tjener til å beskytte det parti av festeelementet som rager ut av borhullet, mot værinnflytelser, This device serves to protect the part of the fastening element that protrudes from the borehole against weather influences,
spesielt fuktighet, som kan føre til en ødeleggelse av festeelementet ved korrosjon. especially moisture, which can lead to the destruction of the fastening element by corrosion.
Hensikten med den foreliggende oppfinnelse er nå å forbedre denne gjenstand og skaffe en korrosjonsbeskyttelse for hele festeelementet. The purpose of the present invention is now to improve this object and provide corrosion protection for the entire fastening element.
Ifølge oppfinnelsen blir dette oppnådd ved at der mellom ekspansjonshylsen og bolten er anordnet en plastring som har en forlengelse som strekker seg utover utenfor murverksoverflaten og overlappes av beskyttelseshylsen. According to the invention, this is achieved by arranging a plastic ring between the expansion sleeve and the bolt, which has an extension that extends outwards outside the masonry surface and is overlapped by the protective sleeve.
Beskyttelseshylsen blir skjøvet inn på bolten enten fra dettes ytre ende eller fra den indre gjengeende før ekspansjonshylsen og ekspansjonslegemet er skrudd på. Det er imidlertid også mulig å påføre beskyttelseshylsen ved sprøyting. Festeelementet er dermed omgitt av beskyttelseshylsen fra undersiden av skruehodet, resp. undersiden av kledningselementet eller det anslag som holder kledningselementet på avstand fra veggen, til et stykke inne i borhullet, fortrinnsvis frem til ekspansjonspartiet. Dermed er festeelementet skjermet mot fuktighet og andre korrosjonsfrembringende værforhold som kan gjøre seg gjeldende en viss dybde inn i muren. Det er derfor ikke nødven-dig å fremstille festeelementene av dyre, rustfrie stål som er vanskelige å bearbeide. I forhold til disse er de merkostnader som den ekstra beskyttelseshylse medfører, uten betydning. The protective sleeve is pushed onto the bolt either from its outer end or from the inner threaded end before the expansion sleeve and the expansion body are screwed on. However, it is also possible to apply the protective sleeve by spraying. The fastening element is thus surrounded by the protective sleeve from the underside of the screw head, resp. the underside of the cladding element or the abutment which keeps the cladding element at a distance from the wall, to a distance inside the borehole, preferably up to the expansion part. In this way, the fastening element is protected against moisture and other corrosion-causing weather conditions that can affect a certain depth into the wall. It is therefore not necessary to manufacture the fastening elements from expensive, stainless steel which is difficult to process. In relation to these, the extra costs that the extra protective sleeve entails are irrelevant.
På grunn av festeelementets holdekraft ligger ekspansjonspartiet så langt inne i borhullet at beskyttelseshylsen, som normalt strekker seg frem til ekspansjonspartiet, kan beskytte festeelementet mot angripende medier som trenger en viss dybde inn i muren. Due to the fastening element's holding power, the expansion part lies so far inside the drill hole that the protective sleeve, which normally extends to the expansion part, can protect the fastening element against attacking media that penetrate a certain depth into the wall.
Den beskyttelseshylse som omgir bolten, spennes inn mellom skruehodet og den nevnte plastring slik at der ved disse ender The protective sleeve that surrounds the bolt is clamped between the screw head and the aforementioned plastic ring so that it ends at these
av beskyttelseshylsen fås en avtetning. Som følge av at plastringen har en diameter som er litt større enn diameteren av ekspansjonshylsen, fås der videre en avtetning av borhullet og festeelementets ekspansjonsområde, slik at beskyttelseshylsen for ekspansjonsområdet bare i ekstreme tilfeller er nødvendig. a seal is obtained from the protective sleeve. As a result of the fact that the plastic ring has a diameter that is slightly larger than the diameter of the expansion sleeve, there is also a sealing of the drill hole and the expansion area of the fastening element, so that the protective sleeve for the expansion area is only necessary in extreme cases.
Ved for lite borhull eller når festeelementet ikke settes omhyggelig inn, vil beskyttelseshylsen kunne skyves noe tilbake, slik at en del av festeelementet ikke lenger er avskjermet. Som følge av forlengelsen og dennes overlapping med beskyttelseshylsen blir dette unngått. If the drill hole is too small or when the fastening element is not inserted carefully, the protective sleeve can be pushed back somewhat, so that part of the fastening element is no longer shielded. As a result of the extension and its overlap with the protective sleeve, this is avoided.
Det nevnte problem unngås fullstendig hvis forlengelsen av plastringen strekker seg utenfor murens overflate. The aforementioned problem is completely avoided if the extension of the plastic ring extends beyond the surface of the wall.
På tegningen er der vist et utførelseseksempel på oppfinnelsen. The drawing shows an embodiment of the invention.
Tegningen viser et festeelement hvor også ekspansjonspartiet er omgitt av en boksformet beskyttelseshylse. The drawing shows a fastening element where the expansion part is also surrounded by a box-shaped protective sleeve.
Det på tegningen viste festeelement består av en ekspansjonshylse 20 som kan utvides ved at et ekspansjonslegeme trekkes inn i ekspansjonshylsen ved hjelp av en bolt 4 med et gjengeparti som strekker seg inn i ekspansjonshylsen 20 og står i inngrep.med ekspansjonslegemet. Det parti 4b av bolten som rager ut av borhullet, tjener til befestigelse av et kledningselement. The fastening element shown in the drawing consists of an expansion sleeve 20 which can be expanded by an expansion body being pulled into the expansion sleeve by means of a bolt 4 with a threaded portion that extends into the expansion sleeve 20 and engages with the expansion body. The part 4b of the bolt that protrudes from the drill hole serves to attach a cladding element.
Til dette formål blir kledningselementet lagt an mot ende-flaten av ekspansjonsbolten 4 og festet til denne endeflate ved hjelp av en hodeskrue. Videre er det parti 4b av bolten 4 som rager utenfor borhullet, forsynt med en boring med innvendige gjenger som hodeskruen kan skrues inn i. For this purpose, the cladding element is placed against the end face of the expansion bolt 4 and fixed to this end face by means of a head screw. Furthermore, there is part 4b of the bolt 4 which projects outside the drill hole, provided with a bore with internal threads into which the head screw can be screwed.
Mellom en plastring 11 og kledningselementet er der anordnet en beskyttelseshylse 10 som omgir både det parti 4b som rager utenfor borhullet, og det parti av bolten 4 som ligger inne i borhullet. Derved fås der en avtetning som beskytter festeelementet mot fuktighet og andre skadelige innflytelser. Between a plastic ring 11 and the cladding element there is arranged a protective sleeve 10 which surrounds both the part 4b which projects outside the borehole, and the part of the bolt 4 which lies inside the borehole. This results in a seal that protects the fastening element against moisture and other harmful influences.
Diameteren av plastringen 11 er noe større enn ytterdia-meteren av ekspansjonshylsen 20, slik at ringen tjener dels som dreiesikring og dels som avtetning av ekspansjonsområdet. The diameter of the plastic ring 11 is somewhat larger than the outer diameter of the expansion sleeve 20, so that the ring serves partly as a rotation lock and partly as a seal of the expansion area.
Videre er der over ekspansjonspartiet 20 satt inn en beskyttelseshylse 21. Denne beskyttelseshylse 21 er utformet boks-lignende og strekker seg ut til den mellom ekspansjonspartiet eller hylsen 20 og bolten 4 anordnede plastring 11. Dermed fås der en omslutning av festeelementet som strekker seg helt fra skruehodet til innføringsenden. Plastringen 11 er også forsynt med en hylseformet forlengelse 22 som rager inn i den beskyttelseshylse 10 som dekker partiet 4b av bolten. Furthermore, a protective sleeve 21 is inserted above the expansion part 20. This protective sleeve 21 is shaped like a box and extends out to the plastic ring 11 arranged between the expansion part or the sleeve 20 and the bolt 4. This results in an enclosure of the fastening element that extends all the way from the screw head to the insertion end. The plastic ring 11 is also provided with a sleeve-shaped extension 22 which projects into the protective sleeve 10 which covers the part 4b of the bolt.
Det er naturligvis også mulig å forbinde beskyttelseshylsene 10 og 21 med hinannen ved liming eller lignende eller å fremstille begge beskyttelseshylser i ett stykke. It is of course also possible to connect the protective sleeves 10 and 21 to each other by gluing or the like or to produce both protective sleeves in one piece.
