Mest nærliggende kjent teknikk er angitt i følgende publikasjoner. The closest prior art is set forth in the following publications.
SE 318330 B omhandler rørinstallasjoner i prefabrikkerte bygningselementer, hvor rørene er forsynt med traktmuffer som opererer i par med oval form. Denne publikasjonen dekker ikke hele det tekniske problemet da den ikke innehar fjærbelastede lederarmer som sikrer enkel trekking av kabler gjennom muffene og den innehar da ingen teknisk løsning på montasje unøyaktigheter og bygg toleranser som naturlig oppstår ved montasje av prefabrikerte elementer. SE 318330 B deals with pipe installations in prefabricated building elements, where the pipes are fitted with funnel sleeves that operate in pairs with an oval shape. This publication does not cover the entire technical problem as it does not contain spring-loaded guide arms that ensure easy pulling of cables through the sleeves and it therefore does not contain any technical solution to assembly inaccuracies and building tolerances that naturally occur when assembling prefabricated elements.
NO 132066 B1 Omhandler skjulte rørinstallasjoner med sneppert muffer i byggeelementer. Sneppert muffer fungerer som et skjøtesystem mellom trekkerør og koblingsbokser som forutsetter at elementene som skjøtes er plassert tilnærmet eksakt ovenfor hverandre. Denne publikasjonen dekker ikke hele det tekniske problemet da den ikke innehar fjærbelastede lederarmer som sikrer enkel trekking av kabler gjennom muffene og den innehar da ingen teknisk løsning på montasje unøyaktigheter og bygg toleranser som naturlig oppstår ved montasje av prefabrikerte elementer. NO 132066 B1 Deals with hidden pipe installations with snap-on sleeves in building elements. Snapped sleeve functions as a joining system between draw pipes and junction boxes, which requires that the elements to be joined are placed almost exactly above each other. This publication does not cover the entire technical problem as it does not contain spring-loaded guide arms that ensure easy pulling of cables through the sleeves and it therefore does not contain any technical solution to assembly inaccuracies and building tolerances that naturally occur when assembling prefabricated elements.
PT87252 A angår lettvekts byggeelementer. PT87252 A concerns lightweight building elements.
Det beskrives et skjøtesystem som PVC rør med muffer som innstøpes i elementer. Denne publikasjonen dekker ikke hele det tekniske problemet da den ikke innehar fjærbelastede lederarmer som sikrer enkel trekking av kabler gjennom muffene og den innehar da ingen teknisk løsning på montasje unøyaktigheter og bygg toleranser som naturlig oppstår ved montasje av prefabrikerte elementer. A joint system is described as PVC pipes with sleeves that are embedded in elements. This publication does not cover the entire technical problem as it does not contain spring-loaded guide arms that ensure easy pulling of cables through the sleeves and it therefore does not contain any technical solution to assembly inaccuracies and building tolerances that naturally occur when assembling prefabricated elements.
Dagens normalt kjente metode for å trekke kabler mellom prefabrikkerte betong elementer er å legge inn trekkerør, hvor det legges en isolasjonskloss i skjøt mellom elementene. Today's normally well-known method for pulling cables between prefabricated concrete elements is to insert a pulling pipe, where an insulating block is placed in the joint between the elements.
Etter at elementene er montert fjernes isolasjonsklossen og det monteres på en ordinær skjøtemuffe som forbinder trekkerørene. After the elements have been assembled, the insulation block is removed and it is mounted on an ordinary joint that connects the draw pipes.
Område rundt skjøtemuffen må gjennstøpes og pusses. Ulempen med denne metoden er at det krever flere arbeidsoperasjoner med flere aktører involvert og at resultatet ikke blir estetisk bra hvis elementene skal stå som eksponert betong. The area around the joint must be recast and plastered. The disadvantage of this method is that it requires several work operations with several actors involved and that the result will not be aesthetically pleasing if the elements are to stand as exposed concrete.
Ofte er overmaling påkrevet for å skjule området som er pusset. Often, overpainting is required to hide the plastered area.
I prefabrikkerte lett elementer, som lette fasader ol. Vil normalt ikke trekkerør for kabling være en del av leveransen per i dag. Dette løses per i dag ved å fore ut på det prefabrikerte elementet for føring av kabler, etter at elementene er ferdig montert på bygget. In prefabricated light elements, such as light facades etc. Normally, pull pipes for cabling will not be part of the delivery as of today. This is currently solved by laying out the prefabricated element for guiding cables, after the elements have been fully assembled on the building.
Oppfinnelsen Figur A eliminerer ovennevnte problemstilling ved at det ikke kreves gjenstøping, pussing eller maling, da selve muffen blir helt innstøpt, uten behov for tilkomst ved kabeltrekking. I prefabrikkerte lette elementer kan oppfinnelsen monteres i hvert element og man unngår da utforing av elementene. The invention Figure A eliminates the above-mentioned problem in that no recasting, plastering or painting is required, as the sleeve itself is completely embedded, without the need for access when pulling cables. In prefabricated light elements, the invention can be mounted in each element and the lining of the elements is then avoided.
Oppfinnelsen Figur A består av to deler der den ene er oval konet muffe (1), og den andre er oval konet muffe med fjærbelastede buede lederarmer (2). The invention Figure A consists of two parts, one of which is an oval tapered sleeve (1), and the other is an oval tapered sleeve with spring-loaded curved guide arms (2).
Disse benyttes alltid i par, montert over og under hverandre i hvert sitt element. These are always used in pairs, mounted above and below each other in each element.
I betong elementer vil de innstøpes und tongproduksjonen på fabrikk. In concrete elements, they will be cast in and tong production at the factory.
I prefabrikkert trekonstruksjon vil de monteres av elementleverandøren på fabrikk. Elektriker vil etter at elementene er montert, trekke ut utløserpinnen(3) som holder lederarmene(4) sammen. Etter dette kan kabler trekkes. Montasje unøyaktigheter og bygg toleranser som medfører at elementene ikke er montert eksakt over hverandre vil fanges opp av lederarmene(4) slik at kabler enkelt kan trekkes. Oppfinnelsen tillater en skjevhet på opptil 50mm mellom bygningselementene. Se figur H, I, J. In prefabricated wooden construction, they will be installed by the element supplier at the factory. After the elements have been installed, the electrician will pull out the release pin (3) that holds the conductor arms (4) together. After this, cables can be pulled. Assembly inaccuracies and construction tolerances which mean that the elements are not mounted exactly above each other will be caught by the guide arms (4) so that cables can be pulled easily. The invention allows a bias of up to 50mm between the building elements. See figures H, I, J.
Muffe(1) vist i figur B består av en oval konet form der innløpsflaten (5) er tilpasset en innsats ring(6) hvor det kan velges innvendig diameter på 16mm til 40mm tilpasset innfesting av trekkerør. The sleeve (1) shown in figure B consists of an oval conical shape where the inlet surface (5) is adapted to an insert ring (6) where an internal diameter of 16mm to 40mm can be selected, adapted to the attachment of the draft tube.
Utløpsflaten(7) er oval hvor lengden alltid har større diameter enn bredden. The outlet surface (7) is oval, where the length always has a larger diameter than the width.
Muffe (2) vist i figur C og D består av en oval konet form der innløpsflaten (5) er tilpasset en innsats ring(6) hvor det kan velges innvendig diameter på 16mm til 40mm tilpasset innfesting av trekkerør. Sleeve (2) shown in figures C and D consists of an oval conical shape where the inlet surface (5) is adapted to an insert ring (6) where an internal diameter of 16mm to 40mm can be selected to fit the attachment of the pull pipe.
Utløpsflaten(7) er oval hvor lengden alltid har større diameter enn bredden. I nedre del på muffeflaten er det etablert et rør(8) som er ført fra muffens(2) innside med lengde som kan tilpasses elementflatens utside. The outlet surface (7) is oval, where the length always has a larger diameter than the width. In the lower part of the socket surface, a pipe (8) has been established which is led from the inside of the socket (2) with a length that can be adapted to the outside of the element surface.
Innsats ring(6) vist i figur E og F er påmontert hengslede lederarmer(4), der de er fjærbelastede(9) og med stag(10) som forbinder armene hvor de er låst sammen via en låsepinne(3). Insert ring (6) shown in figures E and F is mounted on hinged guide arms (4), where they are spring-loaded (9) and with struts (10) that connect the arms where they are locked together via a locking pin (3).
Lederarmer (4) er i buet form hvor lederarmens lengde skal gå på utsiden av muffens(2) utløpsflate(7). Fjær(9) er montert i hempe på lederarmens(4) bakside til hempe på fastpunkt på hengsel(11). Fjær(9) vil trekke lederarmen mot muffens ytterkant når låsepinnen(3) fjernes. Når kabel trekkes vil kabel følge lederamens(4) posisjon inn til muffe(1). Rør(8) til låsepinnen(3) skal kappes jevnt med vegg og proppes. Røret(8) kan benyttes for tilførsel av glidemiddel (silikon), ved trekking av kabler. Guide arms (4) are in a curved shape where the length of the guide arm should go on the outside of the outlet surface (7) of the sleeve (2). Spring (9) is mounted in a hook on the back of the guide arm (4) to a hook on a fixed point on the hinge (11). Spring (9) will pull the guide arm towards the outer edge of the sleeve when the locking pin (3) is removed. When the cable is pulled, the cable will follow the position of the guide frame (4) into the sleeve (1). The pipe (8) for the locking pin (3) must be cut flush with the wall and plugged. The tube (8) can be used for supplying lubricant (silicone), when pulling cables.
I elementet vil kun proppen være synlig på overflaten. In the element, only the plug will be visible on the surface.
For lettelementer med stendere i tre eller stål festes muffe med en festebrakett(12) til stender. Vist i figur G. For lightweight elements with studs in wood or steel, the sleeve is attached to the studs with a mounting bracket (12). Shown in Figure G.
Muffen(1)(2) har hullede flater(13) på hver side for god innfesting i betongelementer. The sleeve (1) (2) has perforated surfaces (13) on each side for good fixing in concrete elements.
Muffen(1)(2) er laget i plastmateriale eller halogenfritt plastmateriale. The sleeve (1)(2) is made of plastic material or halogen-free plastic material.
Bruksområde for oppfinnelsen vil være i alle prefabrikkerte elementer der det er behov for å legge skjult elektrisk røranlegg. Bygningselementene kan være av betong eller, tre- og stålkonstruksjoner der bygningselementene bygges på fabrikk for tiltransport og montasje på byggeplass. Normalt vil det oppstå montasjeavvik når elementene settes på plass. Oppfinnelsen vil eliminere problemet rundt kabeltrekking gjennom elementer da skjøtemuffen sikrer at kabler enkelt kan trekkes selv om elementene er forskjøvet under montasjen innenfor normalt aksepterte toleranser. The scope of application for the invention will be in all prefabricated elements where there is a need to lay hidden electrical piping. The building elements can be made of concrete or wood and steel constructions where the building elements are built in a factory for transport and assembly on site. Assembly deviations will normally occur when the elements are put in place. The invention will eliminate the problem of cable pulling through elements as the splicing sleeve ensures that cables can be easily pulled even if the elements are displaced during assembly within normally accepted tolerances.
