Description

Foreliggende oppfinnelse angår en knutepunktforbindelse for innfesting av horisontale og diagonale stag til et vertikalt stag i et stillassystem omfattende en holder anordnet på vertikalstaget og utformet for mottak av de horisontale og diagonale stagenes innfestingsorganer. The present invention relates to a junction connection for attaching horizontal and diagonal struts to a vertical strut in a scaffolding system comprising a holder arranged on the vertical strut and designed to receive the horizontal and diagonal struts' fastening means.

NO 179877B omtaler en knutepunktforbindelse for innfesting av horisontale og diagonale stag til et vertikalstag i et stilassystem. På vertikalstaget er det montert en sirkelformet holder for mottak at innfestingsorganer på henholdsvis horisontal- og diagonalstagene. Holderen utgjør en sirkelformet kranseplate med en omkrets som omgir vertikalstaget og med en såkalt bølgeformet ytre omkrets, samt med mellomliggende hull for mottak av innfestingsorganer. NO 179877B mentions a junction connection for attaching horizontal and diagonal braces to a vertical brace in a stilt system. A circular holder is mounted on the vertical strut for receiving fastening devices on the horizontal and diagonal struts respectively. The holder forms a circular ring plate with a circumference that surrounds the vertical strut and with a so-called wave-shaped outer circumference, as well as with intermediate holes for receiving fixing devices.

US 2011/0262215 A1, FR 2878273 A1 og US 2006/0039746 A1 omtaler velkjente løsninger på knutepunktforbindleser for stilaskonstruksjoner hvor det anvendes kranseplater med hull for innfestingsorganer som låses i en montert posisjon ved bruk av en kile. US 2011/0262215 A1, FR 2878273 A1 and US 2006/0039746 A1 refer to well-known solutions for junction connectors for stile constructions where flanged plates with holes for fixing means are used which are locked in a mounted position using a wedge.

Det er i dag kjent koblingsanordninger for sammenføyning av konstruksjonsdeler som nevnt ovenfor hvor det benyttes en hakeanordning på den vertikale konstruksjonsdel for mottak av en hekteanordning på den horisontale konstruksjonsdel. Det er videre benyttet konstruksjonsdeler i form av for eksempel kileanordninger som slås inn i koblingsområdet for å avstive selve koblingen. Today there are known coupling devices for joining construction parts as mentioned above, where a hook device is used on the vertical construction part to receive a hook device on the horizontal construction part. Construction parts have also been used in the form of, for example, wedge devices which are driven into the coupling area to stiffen the coupling itself.

De kjente koblingsanordninger av typen som beskrevet ovenfor er normalt utformet spesielt og kun for sitt unike stillassystem. Et stillassystem kan således ikke benyttes sammen med andre stillassystemer. The known coupling devices of the type described above are normally designed specifically and only for their unique scaffolding system. A scaffolding system cannot therefore be used together with other scaffolding systems.

Et annet problem med de kjente løsninger er at kileanordningen er en separat del som ikke er fast forbundet eller lett tilgjengelig ved sammenstilling av koblingsanordningen. Another problem with the known solutions is that the wedge device is a separate part which is not firmly connected or easily accessible when assembling the coupling device.

Innføring og frigjøring av kileanordningen i koblingsanordningen kan også være problematisk og således by på en stor utfordring for operatøren. Insertion and release of the wedge device in the coupling device can also be problematic and thus present a major challenge for the operator.

Et mål med foreliggende oppfinnelse er å tilveiebringe en knutepunktforbindelse for innfesting av horisontale og diagonale stag til et vertikalt stag i fortrinnsvis et stillassystem hvor knutepunktforbindelsen er konstruert slik at den er tilpasset for å kunne benyttes sammen med de fleste større stillastyper som spirstillas, rammestillas, rullestillas, trappetårn, stativ for tildekning med presenning, telt, plasthaller og understøttelse/forskalling. De forskjellige systemene skal således kunne benyttes sammen med hverandre i forskjellige belastningsklasser og til forskjellige formål. An aim of the present invention is to provide a hub connection for attaching horizontal and diagonal struts to a vertical strut in preferably a scaffolding system where the hub connection is designed so that it is adapted to be used together with most larger types of scaffolding such as truss scaffolding, frame scaffolding, rolling scaffolding , stair tower, stand for covering with tarpaulin, tent, plastic halls and support/formwork. The different systems must thus be able to be used together with each other in different load classes and for different purposes.

Et annet mål med foreliggende oppfinnelse er å tilveiebringe en koblingsanordning som er sikker og stabil og tilveiebringer en stiv sammenkoblingsforbindelse. Another object of the present invention is to provide a coupling device which is secure and stable and provides a rigid interconnection connection.

Et annet mål er at en operatør på en enkel og hurtig måte skal kunne sammenstille koblingen. Another goal is for an operator to be able to assemble the connection in a simple and quick way.

Videre skal koblingsanordningen ikke bestå av løse konstruksjonsdeler. Alle nødvendige konstruksjonsdeler skal være montert på konstruksjonsdelene som skal sammenstilles slik at operatøren ikke må lete etter løse deler ved sammenstillingen. Et ytterligere mål er at koblingen skal kunne demonteres på en enkel og hurtig måte. Dette gjelder spesielt ved fjerning av kileanordning som ofte kan være en stor utfordring for operatøren. Furthermore, the coupling device must not consist of loose structural parts. All necessary construction parts must be mounted on the construction parts to be assembled so that the operator does not have to look for loose parts during assembly. A further aim is that the coupling should be able to be dismantled in a simple and quick way. This applies in particular when removing the wedge device, which can often be a major challenge for the operator.

Målene med foreliggende oppfinnelse oppnås ved en knutepunktforbindelse for innfesting av horisontale og diagonale stag til et vertikalstag i et stillassystem omfattende en holder anordnet på vertikalstaget og utformet for mottak av de horisontale og diagonale stagenes innfestingsorganer, idet holderen er i form av en sirkel lignende kransplate med en indre omkrets som omgir vertikalstaget og en bølgeformet/undulert ytre omkretsutforming med et antall hullutforminger mellom den indre og ytre omkrets for mottak av de ulike horisontale og vertikale stagenes innfestingsorganer, The objectives of the present invention are achieved by a node connection for attaching horizontal and diagonal struts to a vertical strut in a scaffolding system comprising a holder arranged on the vertical strut and designed to receive the horizontal and diagonal struts' fastening means, the holder being in the form of a circle-like crown plate with an inner circumference surrounding the vertical strut and a wavy/undulated outer circumference design with a number of hole designs between the inner and outer circumferences for receiving the various horizontal and vertical strut attachment means,

kjennetegnet ved at de horisontale og diagonale stagenes innfestingsorganer har en C-profil lignende utforming bestående av en stegplate med en tilhørende fast øvre flensplate og en leddforbundet nedre flensplate idet de øvre og nedre flensplater er anordnet med spalteåpninger for mottak av et kileorgan, og at den leddforbundene nedre flensplaten er anordnet med spor i sine sidekanter for mottak av en bevegelig gaffelanordning hvor gaffelanordningen med et skaft forløper gjennom en langsgående spalteåpning i stegplaten, og at skaftet er bevegelig anordnet til kileorganet idet kileorganet når gaffelanordningen blir ført inn over og treffer kransplaten, vil bevege seg fra en horisontal hvilestilling over den øvre flensplaten til en vertikal låsestilling slik at innfestingsorganet er låst til kransplaten. characterized in that the fastening means of the horizontal and diagonal struts have a C-profile-like design consisting of a step plate with an associated fixed upper flange plate and an articulated lower flange plate, the upper and lower flange plates being arranged with slit openings for receiving a wedge member, and that the the joints, the lower flange plate is provided with grooves in its side edges for receiving a movable fork device, where the fork device with a shaft extends through a longitudinal slit opening in the step plate, and that the shaft is movably arranged to the wedge member since the wedge member, when the fork device is brought in over and hits the crown plate, will move from a horizontal resting position above the upper flange plate to a vertical locking position so that the attachment member is locked to the flange plate.

Foretrukne utførelsesformer av knutepunktforbindelsen er videre utdypet i kravene 2 til og med 8. Preferred embodiments of the node connection are further elaborated in claims 2 to 8 inclusive.

Foreliggende oppfinnelse skal nå forklares nærmere med henvisning til de vedføyde tegninger, hvor: The present invention will now be explained in more detail with reference to the attached drawings, where:

Med henvisning til figur 1 og figur 2 er en utførelse av en knutepunktforbindelse 1 vist benyttet ved sammenføyning av horisontale stag 50 til et vertikalt stag 40 i et stillassystem. Vertikalstaget 40 er påmontert en holder i form av en sirkel lignende kransplate 5. Det vertikale staget 50 med innfestingsorganer 51 er vist fast anordnet eller låst til kransplaten 5 slik at en sikker og stabil knutepunktforbindelse er oppnådd. Kransplaten 5 er videre vist med ytterligere hullutforminger 9 for mottak av eventuelle innfestingsorganer fra andre systemer. With reference to Figure 1 and Figure 2, an embodiment of a node connection 1 is shown used when joining horizontal struts 50 to a vertical strut 40 in a scaffolding system. The vertical rod 40 is mounted on a holder in the form of a circle similar to the crown plate 5. The vertical rod 50 with fixing means 51 is shown fixedly arranged or locked to the crown plate 5 so that a safe and stable node connection is achieved. The crown plate 5 is also shown with additional hole designs 9 for receiving any fixing devices from other systems.

Med henvisning til figur 3 er selve kransplaten 5 vist med sin karakteristiske utforming med en indre omkrets 5a som omgir vertikalstaget 40 og en bølgeformet ytre omkretsutforming 5b. Den tidligere omtalte utforming 9 for mottak av andre typer systemer er vist. Videre er hullutforminger 8 vist med piler for mottak av innfestingsorganet 51. Hullutformingene 9 er videre utformet slik at innfestingsorganer fra andre systemer også kan benyttes i denne hullutforming hvilket gir en fleksibilitet med hensyn til anvendelse sammen med andre systemer. Den viste kransplate 5 har i utførelsen åtte hullutforminger 8, 9 som er tilpasset for å kunne benyttes sammen med innfestingsorganer for de fleste kjente stillassystemer etc. De åtte hullutforminger 8, 9 omfatter fire første hullutforminger 8 og fire andre hullutforminger 9 idet de første og andre hullutforminger 8, 9 er forskjellige fra hverandre. De fire første hullutforminger 8 og de fire andre hullutforminger 9 er henholdsvis anordnet med 90 grader forskyvninger i forhold til hverandre. De fire første og fire andre hullutforminger 8, 9 er anordnet med henholdsvis 45 graders forskyvning i forhold til hverandre. Kransplatene 5 vil normalt være anordnet til vertikalstaget 40 med en innbyrdes avstand på fortrinnsvis 0,5 meter. Kranseplaten 5 vil normalt ha en tykkelse på fortrinnsvis 10-15 millimeter. With reference to Figure 3, the crown plate 5 itself is shown with its characteristic design with an inner circumference 5a which surrounds the vertical strut 40 and a wave-shaped outer circumference design 5b. The previously mentioned design 9 for receiving other types of systems is shown. Furthermore, hole designs 8 are shown with arrows for receiving the fastening member 51. The hole designs 9 are further designed so that fastening members from other systems can also be used in this hole design, which provides flexibility with regard to use together with other systems. The crown plate 5 shown has in its design eight hole designs 8, 9 which are adapted to be used together with fixing devices for most known scaffolding systems etc. The eight hole designs 8, 9 comprise four first hole designs 8 and four second hole designs 9, the first and second hole designs 8, 9 are different from each other. The first four hole designs 8 and the four second hole designs 9 are respectively arranged with 90 degree offsets in relation to each other. The first four and four second hole designs 8, 9 are arranged respectively with a 45 degree offset in relation to each other. The crown plates 5 will normally be arranged to the vertical strut 40 with a mutual distance of preferably 0.5 metres. The crown plate 5 will normally have a thickness of preferably 10-15 millimetres.

Figur 4a-d viser innfestingsorganet 51 anordnet til horisontalstaget 50. Innfestingsorganet 51 har en C-profil lignende utforming bestående av en stegplate 52 med en tilhørende fast øvre flensplate 53 og en leddforbundet nedre flensplate 60. De øvre og nedre flensplater 53, 60 er anordnet med spalteåpninger 54, 61 for mottak av et kileorgan 70. Figur 4a viser innfestingsorganet 51 i en hvilestilling hvor innfestingsorganets kileorgan 70 er i en hvilestilling i et spor i det øvre området av vertikalstaget 40. Figur 4b og 4c viser C-profilen idet denne innføres rundt kransplaten 5 hvorved kileorganet 70 forflyttes fra hvilestilling og føres gjennom henholdsvis den øvre flensplate 53, hullutformingen 8 i kransplaten 5 og den nedre flenspalte 60 hvorved innfestingsorganet låses til kransplaten 5 som vist i figur 4d. For å forflytte kileorganet 70 fra hvilestilling til låsestilling er den leddforbundet nedre flensplate 60 anordnet med spor 62 i sine sidekanter for mottak av en bevegelig gaffelanordning 80 hvor gaffelanordningens skaft 82 forløper gjennom en langsgående spalteåpning 52a i stegplaten 52. Skaftet 82 er bevegelig anordnet til kileorganet 70 hvorved når gaffelanordningen 80 ved innføring treffer kransplaten 5 forflyttes kileorganet 70 fra en horisontal hvilestilling over øvre flensplate 53 til en vertikal låsestilling hvor innfestingsorganet 51 låses til kransplaten 5. Innfestingsorganet 51 vil således ved innføring rundt kransplaten automatisk låses til denne. Som en ekstra sikring kan kilen 70 eventuelt gis et lett slag på sin øvre ende. Ved demontering av knuteforbindelsen kan kilens nedre ende påføres et lett hammerslag hvilket vil løsgjøre og skyve kilen oppover og kilen 5 kan dras opp og legges bakover i hvileposisjon. Figure 4a-d shows the attachment member 51 arranged to the horizontal strut 50. The attachment member 51 has a C-profile similar design consisting of a step plate 52 with an associated fixed upper flange plate 53 and an articulated lower flange plate 60. The upper and lower flange plates 53, 60 are arranged with slit openings 54, 61 for receiving a wedge member 70. Figure 4a shows the attachment member 51 in a rest position where the attachment member's wedge member 70 is in a rest position in a groove in the upper area of the vertical strut 40. Figures 4b and 4c show the C-profile as it is inserted around the flange plate 5, whereby the wedge member 70 is moved from its rest position and passed through the upper flange plate 53, the hole design 8 in the flange plate 5 and the lower flange slot 60, whereby the fastening member is locked to the flange plate 5, as shown in figure 4d. In order to move the wedge member 70 from the resting position to the locking position, the articulated lower flange plate 60 is provided with grooves 62 in its side edges for receiving a movable fork device 80, where the fork device's shaft 82 extends through a longitudinal slit opening 52a in the step plate 52. The shaft 82 is movably arranged to the wedge member 70 whereby when the fork device 80 hits the flange plate 5 during insertion, the wedge member 70 is moved from a horizontal rest position above the upper flange plate 53 to a vertical locking position where the fastening member 51 is locked to the flange plate 5. The fastening member 51 will thus automatically be locked to this when inserted around the flange plate. As an additional safeguard, the wedge 70 can optionally be given a light blow on its upper end. When disassembling the knot connection, the lower end of the wedge can be applied with a light hammer blow, which will loosen and push the wedge upwards and the wedge 5 can be pulled up and placed backwards in the resting position.

Med henvisning til figur 5 og 6 er holderen ifølge oppfinnelsen vist montert på et vertikalstag og benyttet sammen med innfestingsorganer fra et annet stillassystem. Hullutformingene 9 i kransplaten 5 er her benyttet, og det oppnås en stabil og sikker knutepunktforbindelse. Figur 7 viser hulleutformingene 9 med piler for mottak av innfestingsorganene for dette systemet. With reference to Figures 5 and 6, the holder according to the invention is shown mounted on a vertical strut and used together with fixing devices from another scaffolding system. The hole designs 9 in the crown plate 5 are used here, and a stable and secure junction connection is achieved. Figure 7 shows the hole designs 9 with arrows for receiving the attachment members for this system.

Knutepunktforbindelsen 1 har et bredt anvendelsesområde da den også kan benyttes i forbindelse med et stort antall kjente systemer. Videre ved anvendelse av det omtalte innfestingsorganet 51 vil man oppnå en enkel og tidsbesparende «automatisk» låsing mellom kransplate og stag uten løse konstruksjonsdeler. The node connection 1 has a wide range of applications as it can also be used in connection with a large number of known systems. Furthermore, by using the aforementioned fixing device 51, a simple and time-saving "automatic" locking between the crown plate and the strut will be achieved without loose structural parts.
