Endelig angår opfindelsen en anvendelse af et dybelsystem ifølge opfindelsen til fastgørelse af isoleringsmateriale ved præfabrikation af betonelementer ved en fremgangsmåde ifølge opfindelsen.Finally, the invention relates to the use of a dipping system according to the invention for securing insulating material in the prefabrication of concrete elements by a method according to the invention.
Den kendte teknikThe prior art
De på markedet eksisterende dybler, er i de fleste tilfælde baseret på at fastholde isolering til eksisterende flader, såsom facader - tagflader -sokler etc. Det vil sige, at de er baseret på efterisolering/udskiftning af isolering på bestående flader af ovennævnte bygningsdele.In most cases, the existing dents on the market are based on retaining insulation to existing surfaces, such as facades - roof surfaces - bases etc. That is, they are based on post-insulation / replacement of insulation on existing surfaces of the above-mentioned building parts.
De ovennævnte dybler er derfor udformet således, at de fastholdes mekanisk med en skrue eller en ekspansionsdel i de bestående flader. Dyblerne monteres ved, at de bores igennem isoleringen og ind i de bestående flader, såsom murværk, lecabeton, gasbeton, beton, træunderlag etc.The above-mentioned dips are therefore designed to be mechanically fixed with a screw or an expansion part in the existing surfaces. The dowels are mounted by drilling through the insulation and into the existing surfaces, such as masonry, lecabeton, gas concrete, concrete, wood substrates etc.
Et eksempel herpå kan ses i DE 10139261 A1, hvor der under fremstillingen af et isoleringslag indsættes et hylster, der går igennem isoleringslaget og igennem dette hylster skrues en dybelskrue ind i muren eller væggen.An example of this can be seen in DE 10139261 A1, where during the manufacture of an insulating layer, a casing passing through the insulating layer is inserted and through this casing a double screw is screwed into the wall or wall.
Karakteristisk for disse ovennævnte dybler er, at de skal have et fast underlag for at fæstes. Desuden lider de ovennævnte dybler alle af den ulempe, at man ikke kan se, om dyblerne bliver skruet tilstrækkeligt langt ind i de eksisterende flader, da isoleringslaget gør det umuligt at se fladen, som dyblerne skal forankres i. Dette kan medføre, at dyblerne ikke bliver fastgjort ordentligt i fladen, hvilket medfører risiko for et defekt element, idet bæreevnen i fastgørelsen af isoleringen forringes i elementet, hvis der er mange dybler, der ikke er tilstrækkeligt fastgjort i fladen. Dette er især et problem, hvis betonelementet er konstrueret med en overflade ovenpå isoleringslaget, der også fastholdes af dyblerne, eller hvis der er påført et eller flere pudslag direkte på den ydre overflade af isoleringen, f.eks. som beskrevet i EP 2224071 A1.Characteristic of these aforementioned dips is that they must have a firm surface to attach. Furthermore, the aforementioned dips all suffer from the disadvantage of not seeing if the dips are screwed far enough into the existing surfaces, as the insulation layer makes it impossible to see the surface into which the dips are to be anchored. This can cause the dips not to is fixed firmly in the surface, causing the risk of a defective element, with the load bearing capacity of the insulation being impaired in the element if there are many dents not sufficiently fixed in the surface. This is especially a problem if the concrete element is constructed with a surface on top of the insulation layer which is also held by the dips, or if one or more plaster layers are applied directly to the outer surface of the insulation, e.g. as described in EP 2224071 A1.
Når man skal fastholde isolering i forbindelse med fremstilling af præfabrikerede betonelementer, opstår der også et problem med ”det faste underlag”. Enten er underlaget for frisk til at forankre noget, hvis det ønskes, at isoleringen og dermed også dyblerne monteres hurtigt efter udstøbningen af betonelementerne. Alternativt må monteringen af isoleringen og dyblerne afvente at betonelementet er afhærdet, hvorefter man må benytte ovennævnte dybler til montering i det nu faste underlag. Dette medfører dog, at betonelementets samlede produktionstid bliver lang, da tiden til afhærdningen af betonen indgår som et selvstændigt trin i fremstillingen af betonelementet. Det tager omkring 12 timer for betonen at hærde tilstrækkeligt meget til, at man kan fæste de ovennævnte dybler i betonelementets flader. Det er således ikke muligt at fremstille betonelementet på én dag, med de ovennævnte dybelsystemer eller dybler til forankring af isoleringen i betonfladen.When maintaining insulation in connection with the manufacture of prefabricated concrete elements, there is also a problem with the "solid substrate". Either the substrate is too fresh to anchor something if it is desired that the insulation and thus also the dips be mounted quickly after the concrete elements are cast. Alternatively, the mounting of the insulation and the dowels must wait for the concrete element to harden, after which the above-mentioned dowels must be used for mounting in the now solid substrate. However, this means that the total production time of the concrete element becomes long, as the time for the curing of the concrete is included as an independent step in the manufacture of the concrete element. It takes about 12 hours for the concrete to cure enough to allow the aforementioned dips to be affixed to the surfaces of the concrete element. Thus, it is not possible to manufacture the concrete element in one day, with the above mentioned dip systems or dips for anchoring the insulation in the concrete surface.
Et andet problem med at fremstille præfabrikerede isolerede betonelementer, er de mange tykkelser, som betonelementerne fremstilles i. Hver byggesag har sine egne krav til betonelementernes U-værdi, og dermed til isoleringstykkelsen, samt krav vedrørende valg mellem forskellige typer isolering, hvor isoleringens λ-værdi er bestemmende for isoleringstykkelsen. Dette medfører, at betonelementfabrikken skal lagerføre dybler i mange forskellige længder, for at kunne fremstille forskellige betonelementer med forskellige lagtykkelser af isolering, så de opfylder de krav, der stilles til elementernes U-værdi ved de enkelte byggesager.Another problem with producing prefabricated insulated concrete elements is the many thicknesses in which the concrete elements are manufactured. Each building case has its own requirements for the U-value of the concrete elements, and thus for the insulation thickness, as well as requirements regarding the choice of different types of insulation, where the insulation λ- value determines the insulation thickness. This means that the concrete element factory must stock dips of many different lengths in order to be able to manufacture different concrete elements with different layer thicknesses of insulation to meet the requirements for the U-value of the elements in the individual construction cases.
US 2005/108985 A1 beskriver en betonvæg, som omfatter et betonelement med isoleringsmateriale, der er fastgjort med et dybelsystem, som omfatter en fastgørelsesdel og et dybelhoved. Dybelhovedet har en forankringsskive og en rørdel med en boring. Forud for udstøbningen af betonfladen, er fastgørelsesdelen blevet fæstnet til armeringen, og fastgørelsesdelen står i det væsentlige vinkelret på den støbte betonflade.US 2005/108985 A1 discloses a concrete wall which comprises a concrete element with insulating material secured with a dipping system comprising a fastening part and a dip head. The dip head has an anchoring disc and a pipe part with a bore. Prior to the casting of the concrete surface, the securing member has been attached to the reinforcement and the securing member is substantially perpendicular to the cast concrete surface.
Imidlertid er der et stort ønske om alternative dybelsystemer og måder til at kunne fremstille et isoleret betonelement, hvor de arbejdsprocesser, der skal udføres i fremstillingen kan foregå i løbet af den kortest mulige tid, og med færrest mulige pauser i produktionen, som f.eks. de nødvendige tørretider for beton og andre hærdende materialer normalt medfører.However, there is a great desire for alternative immersion systems and ways to produce an insulated concrete element, where the work processes to be carried out in the production can take place in the shortest possible time, and with the fewest possible breaks in production, such as . the necessary drying times for concrete and other hardening materials usually entails.
Formålet med opfindelsen.The object of the invention.
Den foreliggende opfindelse løser ovennævnte ulemper ved den kendte teknik på en alternativ måde.The present invention solves the above-mentioned disadvantages of the prior art in an alternative way.
Den foreliggende opfindelse løser også ovennævnte ulemper ved den kendte teknik, og tilvejebringer et dybelsystem og en fremgangsmåde til fastgøring af isolering på et betonelement, der tillader at fremstille et præfabrikeret isoleret betonelement, så alle arbejdsprocesser kan udføres i løbet af én arbejdsdag. Desuden medfører opfindelsen, at hærdningen af betonen således ikke længere er en begrænsning for, hvornår de næste trin i færdiggørelsen af betonelementet skal foregå, og hærdningen af betonlaget i betonelementet kan foregå imens betonelementet færdiggøres samt efter endt montering af isolering og eventuel påførelse af et ydre pudslag på isoleringslaget eller beklædning af overfladen af isoleringslaget med en fast plade eller andre almindeligt forekommende beklædningstyper.The present invention also solves the above-mentioned drawbacks of the prior art, and provides a dipping system and method of securing insulation to a concrete element which allows to manufacture a prefabricated insulated concrete element so that all work processes can be performed in one working day. In addition, the invention means that the curing of the concrete is no longer a limitation on when the next steps in the finalization of the concrete element must take place, and the hardening of the concrete layer in the concrete element can take place while the concrete element is completed and after finishing the insulation and possible application of an exterior. plating on the insulating layer or lining the surface of the insulating layer with a fixed plate or other commonly used cladding types.
Desuden er det også formålet med opfindelsen at muliggøre, at det undervejs i fastgørelsen af dybelsystemet er muligt at følge med i, at dybelsystemet bliver fastgjort korrekt og samtidigt tilstrækkeligt sikkert i betonelementernes flade, hvilket er med til at sikre, at bæreevnen for alle dyblerne i de fremstillede betonelementer er langt mere ensartet end de kendte isoleringsdybler eller dybelsystemer tillader.Furthermore, it is also an object of the invention to make it possible during the fixing of the dipping system to follow that the dipping system is fastened correctly and at the same time sufficiently securely in the surface of the concrete elements, which helps to ensure the carrying capacity of all the dips in the the concrete elements manufactured are far more uniform than the known insulation dips or dipping systems allow.
Beskrivelse af opfindelsen.Description of the Invention
Dette formål opnås ved en fremgangsmåde af den indledningsvist nævnte art, som omfatter at dybelsystemets fastgørelsesdele fastgøres omkring en armering i betonelementet med en betonflade forud for støbning heraf, hvorved fastgørelsesdelene fastgøres i den armerede betonflade, og fastholdes i en position, hvor de i det væsentlige står vinkelret ud fra den støbte betonflade, at isoleringsmaterialet lægges på den udstøbte betonflade, således at fastgørelsesdelene trænger igennem isoleringsmaterialet, at der på hver af fastgørelsesdelene, monteres et dybelhoved, som har en forankringsskive og en rørdel med en gennemgående boring, idet fastgørelsesdelen føres igennem boringen og at rørdelen trykkes ned i isoleringsmaterialet, så forankringsskiven i det væsentlige flugter med den fri overflade heraf, og at fastgørelsesdelen ombukkes omkring en forankringsflade i en slids i dybelhovedet, for fastholdelse af dybelhovedet på fastgørelsesdelen og dermed fastholdelse af isoleringsmaterialet på betonelementet.This object is achieved by a method of the aforementioned kind which comprises attaching the immersion parts of the immersion system to a reinforcement in the concrete element with a concrete surface prior to casting thereof, whereby the attachment parts are fixed in the reinforced concrete surface and are retained in a position where the is perpendicular to the cast concrete surface that the insulating material is laid on the cast concrete surface, so that the fasteners penetrate the insulating material, mounting on each of the fasteners a dip head having an anchoring disc and a pipe part with a through bore passing through the fastening part. the bore and the pipe portion being pressed into the insulating material so that the anchoring disc aligns substantially with the free surface thereof, and that the attachment portion is wrapped around an anchorage surface in a slot in the diphead, for retention of the diphead on the attachment portion and thus retained e of the insulation material on the concrete element.
Ovennævnte formål med opfindelsen opnås tillige med et dybelsystem af den indledningsvist nævnte art til fastgørelse af isoleringsmateriale på et betonelement og til brug ved fremgangsmåden ifølge opfindelsen, hvor fastgørelsesdelen omfatter en tråd i form af et i det væsentlige retlinet trådstykke med en krogdel til fastgørelse omkring armeringen i en armeret betonflade i betonelementet forud for udstøbningen af betonfladen, og at dybelhovedet har en forankringsskive og en rørdel, og har en gennemgående boring igennem hvilken boring den i det væsentlige retlinede del af trådstykket kan indføres i forbindelse med fastgørelsen af dybelhovedet, og at dybelhovedet desuden har en åbning i form af en slids i forankringsskiven og rørdelen, hvor slidsen har en bredde, der tillader passage af trådstykket ved ombukning af fastgørelsesdelens trådstykke omkring en forankringsflade i slidsen.The above object of the invention is also achieved with a dipping system of the type mentioned above for attaching insulating material to a concrete element and for use in the method according to the invention, wherein the fastening part comprises a thread in the form of a substantially rectilinear piece with a hook part for fastening around the reinforcement. in a reinforced concrete surface in the concrete element prior to the casting of the concrete surface, and that the dip head has an anchoring disc and a pipe part, and has a through bore through which bore the substantially rectilinear portion of the wire piece can be inserted in connection with the fixing of the dip head, and that the dip head in addition, has an opening in the form of a slot in the anchoring disc and the pipe portion, the slot having a width which permits passage of the thread piece by bending the thread piece of the fastening member around an anchoring surface in the slot.
I en udførelsesform af fremgangsmåden påføres fastgørelsesdelen et rørstykke, som forud for ombukningen af fastgørelsesdelen placeres i boringen i rørdelen af dybelhovedet. Rørstykket føres med ud gennem slidsen under ombukningen af fastgørelsesdelen over forankringsfladen. I en tilsvarende udførelsesform af dybelsystemet omfatter dette et rørstykke, der i forbindelse med fastgørelsen af dybelsystemet er placeret omkring trådstykket i boringen, og at slidsen har en bredde, der tillige tillader passage af rørstykket. Herved opnås en præcis ombukning af fastgørelsesdelen, hvilket medfører en ensartet og tilstrækkeligt stor forspænding af fastgørelsesdelens trådstykke. Dette sikrer også, at dybelhovedet fastholdes på fastgørelsesdelen, og at isoleringsmaterialet fastholdes på betonelementet med den ønskede styrke.In one embodiment of the method, the attachment member is applied to a pipe piece which, prior to the bending of the attachment member, is placed in the bore in the pipe member of the dipping head. The pipe piece is carried out through the slot during the folding of the fastening part over the anchoring surface. In a similar embodiment of the dipping system, this comprises a piece of pipe which, in connection with the attachment of the dipping system, is placed around the piece of wire in the bore, and that the slot has a width which also permits passage of the pipe piece. This results in a precise bending of the fastening part, which results in a uniform and sufficiently large biasing of the thread piece of the fastening part. This also ensures that the dipping head is retained on the attachment member and that the insulating material is retained on the concrete member with the desired strength.
Alternativt kan der til ombukningen af trådstykket anvendes et værktøj, der kan gribe omkring en tilsvarende del af trådstykket, så tråden bukkes præcist over forankringsfladen uden at anvende rørstykket. Værktøjets gribefunktion skal i givet fald være udformet, så det let kan frigøres fra trådstykket efter at trådstykket er ført ud gennem slidsen og er blevet bukket ned i isoleringsmaterialet.Alternatively, for the bending of the thread piece, a tool can be used which can grip about a corresponding portion of the thread piece so that the thread is bent precisely over the anchoring surface without using the tube piece. The gripping function of the tool, if any, must be designed so that it can be easily released from the wire piece after the wire piece has passed through the slot and has been bent into the insulating material.
I en udførelsesform af fremgangsmåden ombukkes en fri ende af fastgørelsesdelen omkring den frie ende af rørstykket forud for ombukningen af fastgørelsesdelen og det medfølgende rørstykke over forankringsfladen. Herved forspændes fastgørelsesdelen yderligere, hvilket yderligere øger styrken af fastgørelsen af isoleringen på betonelementet.In one embodiment of the method, a free end of the fastening member is wrapped around the free end of the pipe piece prior to the folding of the fastener and the accompanying pipe piece over the anchoring surface. This further tightens the fastener, further increasing the strength of the fastening of the insulation to the concrete element.
I en udførelsesform af fremgangsmåden lægges en isoleringsstrimmel ind i den åbning, der fremkommer i isoleringsmaterialet efter ombukningen af fastgørelsesdelen og det medfølgende rørstykke over forankringsfladen. Herved opnås en betydelig reduktion i risikoen for at der opstår en kuldebro ved dyblerne.In one embodiment of the method, an insulating strip is inserted into the opening which appears in the insulating material after the bending of the fastening member and the accompanying pipe piece over the anchoring surface. This results in a significant reduction in the risk of a cold bridge at the dips.
Det foretrækkes, at rørdelen af dybelhovedet i dybelsystemet omfatter en tilspidset del i den ende af rørdelen, der vender væk fra forankringsskiven. Herved, kan dybelhovedet let trykkes ned i isoleringsmaterialet.It is preferred that the pipe portion of the dip head in the dip system comprises a tapered portion at the end of the pipe portion facing away from the anchoring disc. Hereby, the deep head can be easily pressed into the insulating material.
Ved at dybelhovedet er udformet med fordybninger og/eller åbninger i forankringsskiven bliver det sikret, at et pudslag, der efter følgende påføres isoleringsmaterialets frie overflade, også vil hæfte på dybelhovederne.By forming the dip head with recesses and / or openings in the anchoring disc, it is ensured that a plaster stroke, which is subsequently applied to the free surface of the insulating material, will also adhere to the dip heads.

Dybelsystemet består i det væsentlige af tre dele: Et dybelhoved med en forankringsskive 1 og en rørdel 2, en fastgørelsesdel og et rørstykke 8, der monteres inde i rørdelen 2 og omkring fastgørelsesdelen.The dipping system consists essentially of three parts: a dipping head with an anchoring disc 1 and a pipe part 2, a fastening part and a pipe piece 8 which is mounted inside the pipe part 2 and around the fastening part.
Dybelhovedets forankringsskive 1 og rørdelen 2, er fortrinsvis er støbt i ét stykke.The anchor disc 1 and the tube part 2 of the dip head are preferably molded in one piece.
Fastgørelsesdelen omfatter et trådstykke 7, som bør have en krogdel 7a, der kan gribe omkring armeringen, der skal støbes ind i betonvæggen. Krogdelens udformning er ikke essentiel, da det blot skal kunne gribe omkring armeringen og gerne stå i det væsentlige vinkelret op fra den udstøbte betonoverflade.The fastening member comprises a wire piece 7 which should have a hook portion 7a capable of gripping around the reinforcement to be cast into the concrete wall. The design of the hook part is not essential, as it should simply be able to grip around the reinforcement and preferably stand up perpendicular to the cast concrete surface.
En velegnet fastgørelsesdel er vist i fig. 1c og omfatter et lige trådstykke 7, der i sin ene ende har en krogdel 7a, der fastgøres omkring armeringen A, der skal indstøbes i betonelementets armerede flade. Forud for udstøbningen af den armerede flade bliver et antal fastgørelsesdele 7, svarende til det nødvendige antal dybler, således fastgjort til armeringen i en passende jævn fordeling over hele betonelementets areal. Alternativt kan fastgørelsesdelens trådstykke 7 monteres til armeringen i betonelementet med andre velkendte fastgørelsesmetoder, som f.eks. anvendes ved fastgørelse af murbindere. Efter fastgørelsen står trådstykkerne 7 i det væsentlige vinkelret op fra betonelementets væg, således at isolering 9 med den ønskede lagtykkelse kan trykkes ned over de lodretstående trådstykker 7 umiddelbart efter udstøbning af betonelementets armerede flade.A suitable attachment member is shown in FIG. 1c and comprises a straight piece of wire 7 having at one end a hook portion 7a which is fastened around the reinforcement A to be embedded in the reinforced surface of the concrete element. Prior to the casting of the reinforced surface, a number of fasteners 7, corresponding to the required number of dips, are thus fixed to the reinforcement in a suitable even distribution over the entire area of the concrete element. Alternatively, the thread piece 7 of the fastener may be mounted to the reinforcement in the concrete member by other well known fastening methods such as e.g. used when fastening wall binders. After attaching, the wire pieces 7 are substantially perpendicular to the wall of the concrete element, so that insulation 9 of the desired layer thickness can be pressed down over the vertical wire pieces 7 immediately after casting the reinforced surface of the concrete element.
Da fastgørelsesdelen af dybelsystemet, dvs. trådsstykket 7, indstøbes i betonelementets armerede flade, og er forankret til armeringen, opnås stor sikkerhed for at dyblernes bæreevne er veldefineret og i det væsentlige konstant for alle dyblerne. Desuden er positionen af dyblerne konstant og veldefineret i alle retninger, dvs. både i et plan parallelt med den bærende flade, vinkelret herpå, og dermed ikke kan rotere i forhold til betonelementet.Since the attachment portion of the dip system, i.e. the wire piece 7, embedded in the reinforced surface of the concrete element, and anchored to the reinforcement, provides great assurance that the bearing capacity of the dips is well defined and substantially constant for all dips. Furthermore, the position of the dips is constant and well defined in all directions, ie. both in a plane parallel to the supporting surface, perpendicular thereto, and thus unable to rotate relative to the concrete element.
Trådstykket 7 har en længde, der tillader, at det kan anvendes til samtlige tykkelser af isoleringslaget 9, således, at der kun anvendes en standardlængde af trådstykket 7. Diameteren på trådstykket 7 skal give dybelsystemet tilstrækkelig styrke til at bære såvel isoleringslag 9, som et beklædnings- og/eller pudslag, der påføres ovenpå overfladen af isoleringslaget 9. Det har således vist sig, at trådtykkelser med en diameter mellem 2 og 6 mm, herunder fortrinsvis mellem 2,5 mm og 4,5 mm, idet en diameter på cirka 3 mm har vist sig at være tilstrækkelig for de fleste byggeopgaver. Trådstykkerne 7 er udført i et materiale, fortrinsvis af metal, der tåler indstøbning i beton og samtidigt hermed besidder en passende styrke til at bære isolering 9 og et eventuelt puds- eller beklædningslag, og er f.eks. fremstillet af rustfrit stål.The wire piece 7 has a length which allows it to be used for all thicknesses of the insulating layer 9, so that only a standard length of the wire piece 7 is used. The diameter of the wire piece 7 must give the immersion system sufficient strength to carry both insulating layer 9 and an insulating layer 9. Thus, it has been found that wire thicknesses having a diameter of between 2 and 6 mm, including preferably between 2.5 mm and 4.5 mm, with a diameter of approx. 3 mm has been found to be sufficient for most construction tasks. The wire pieces 7 are made of a material, preferably of metal, which can withstand casting in concrete and at the same time possess an appropriate strength to support insulation 9 and any plaster or cladding layer, and are e.g. made of stainless steel.
Dybelhovedet i dybelsystemet ifølge opfindelsen, er vist i perspektiv i fig. 1a, og har en forankringsskive 1 med en gennemgående åbning T, der fortrinsvis er placeret centralt på forankringsskiven 1, og en rørdel 2. En slids 3 forløber i rørdelen 2 og i forankringsskiven 1, og bunden af denne slids 3 har en lille forhøjning, der danner en forankringsflade 4, hvis funktion vil blive beskrevet nedenfor. Dybelhovedet er fremstillet i et materiale, f.eks. plast eller metal, med en passende brudstyrke. Det foretrækkes, at dybelhovedet er fremstillet af plast, da dette reducerer risikoen for at der opstår en kuldebro i området omkring dybelhovedet.The dip head of the dip system according to the invention is shown in perspective in FIG. 1a, and has an anchoring disc 1 with a through opening T, preferably located centrally on the anchoring disc 1, and a pipe part 2. A slot 3 extends into the pipe part 2 and to the anchoring disk 1, and the bottom of this slot 3 has a slight elevation. forming an anchoring surface 4, the function of which will be described below. The dipping head is made of a material, e.g. plastic or metal, with an appropriate breaking strength. It is preferred that the dip head is made of plastic as this reduces the risk of a cold bridge occurring in the area around the dip head.
I en udførelsesform af dybelsystemet ifølge opfindelsen har forankringsskiven 1 et antal fordybninger og/eller gennemgående åbninger 1”, der er jævnt fordelt omkring den centrale åbning T. Disse fordybninger og/eller åbninger 1” sikrer, at et eventuelt pudslag, også vil hæfte på selve forankringsskiven 1, når det påføres på overfladen af isoleringen 9.In one embodiment of the dipping system according to the invention, the anchor disc 1 has a number of recesses and / or through openings 1 "evenly distributed around the central opening T. These recesses and / or openings 1" ensure that any plaster stroke will also adhere to the the anchor disk 1 itself when applied to the surface of the insulation 9.
Dybelhovedets rørdel 2 har en i det væsentlige cylindrisk del 2’ samt en tilspidset del 2”, og såvel den cylindriske del 2’ og den tilspidsede del 2” har en indre aksialt forløbende boring 5, 6. Forankringsskivens centrale åbning T er forbundet til boringen 5, 6 i rørdelen 2, idet centerpunktet for åbningen 1’ i forankringsskiven 1 sammenfalder med den aksiale centerlinie for boringen 5, 6 i rørdelen 2. Den tilspidsede ende 2” sikrer, at dybelhovedet kan presses ned i isoleringsmaterialet 9, så forankringsskiven 1 i det væsentlige flugter med overfladen af isoleringsmaterialet 9.The deep-head tube portion 2 has a substantially cylindrical portion 2 'as well as a tapered portion 2 ", and both the cylindrical portion 2' and tapered portion 2" have an inner axially extending bore 5, 6. The central opening T of the anchor disc is connected to the bore 5, 6 in the pipe part 2, the center point of the opening 1 'of the anchor disk 1 coincides with the axial center line of the bore 5, 6 in the pipe part 2. The tapered end 2 "ensures that the dip head can be pressed down into the insulating material 9, so that the anchor disk 1 in substantially flush with the surface of the insulating material 9.
Boringen 6 i den tilspidsede del 2” af rørdelen 2 har fortrinsvis en diameter, der er lidt større end diameteren på trådstykket 7, og boringen 5 i den cylindriske del 2’ af rørdelen 2 har fortrinsvis en diameter, der er lidt større end rørstykket 8.The bore 6 of the tapered portion 2 "of the pipe portion 2 preferably has a diameter slightly larger than the diameter of the wire piece 7, and the bore 5 of the cylindrical portion 2 'of the pipe portion 2 preferably has a diameter slightly larger than the pipe piece 8. .
Rørstykket 8 har en indre diameter, der er lidt større end trådstykkets 7 diameter, og den ydre diameter af rørstykket 8 er lidt mindre end bredden på slidsen 4 i forankringsskiven 1 og rørdelen 2. Rørstykkets 8 længde er større end længden af boringen 5. Når rørstykket 8 er indsat i boringen 5 vil rørstykket 8 rage et stykke udenfor dybelhovedet, så det bliver muligt at gribe om det med et værktøj, se fig. 6a og 6d. Rørstykket 8 er fremstillet af et materiale, sikrer, at det ikke kan gå itu, når tråden og rørstykket skal bukkes ned i isoleringen 9, og er f.eks. fremstillet af metal, f.eks. rustfrit stål, eller alternativt af et egnet plastmateriale.The pipe piece 8 has an inner diameter slightly larger than the diameter of the wire piece 7 and the outer diameter of the pipe piece 8 is slightly smaller than the width of the slot 4 in the anchoring disc 1 and the pipe part 2. The length of the pipe piece 8 is greater than the length of the bore 5. When the pipe piece 8 is inserted into the bore 5, the pipe piece 8 will project a bit outside the dipping head, so that it will be possible to grip it with a tool, see fig. 6a and 6d. The pipe piece 8 is made of a material, ensures that it cannot break when the wire and the pipe piece have to be bent into the insulation 9, and is e.g. made of metal, e.g. stainless steel, or alternatively of a suitable plastic material.
Forankringsskiven 1 og rørdelen 2 er i fig. 1a vist som cirkulært henholdsvis cirkulært cylindrisk, men er ikke begrænset hertil, idet såvel forankringsskiven 1 og/eller rørdelens 2 tværsnit eksempelvis også kan være ovalt eller polygonisk, f.eks. kvadratisk, rektangulært eller heksagonalt. Den tilspidsede del 2” af rørdelen 2 kan på tilsvarende vis også antage form som en keglestub med ovalt tværsnit eller have form som en pyramidestub med polygonalt tværsnit.The anchoring disk 1 and the pipe part 2 are shown in FIG. 1a are shown as circular and circular cylindrical, respectively, but are not limited thereto, since both the anchoring disc 1 and / or the cross section of the pipe member 2 can, for example, also be oval or polygonal, e.g. square, rectangular or hexagonal. Similarly, the tapered portion 2 ”of the pipe portion 2 may also take the form of an oval cross-sectional cone or have the shape of a polygonal cross-sectional pyramid.
Opfindelsen angår også en fremgangsmåde til fastgørelse af et isoleringslag på et betonelement, idet der anvendes et dybelsystem ifølge opfindelsen.The invention also relates to a method of attaching an insulating layer to a concrete element, using a dipping system according to the invention.
Når et betonelement skal fabrikeres, forberedes udstøbningen af den bærende flade af betonelementet ved, at armeringen R lægges i en støbeform/forskalling. Forud for udstøbningen af den armerede flade i betonelementet fastgøres et passende antal fastgørelsesdele omkring armeringen R, idet krogdelen 7a monteres omkring armeringen R, f.eks. som illustreret på fig. 1c.When a concrete element is to be fabricated, the casting of the supporting surface of the concrete element is prepared by placing the reinforcement R in a mold / formwork. Prior to the casting of the reinforced surface in the concrete element, an appropriate number of fasteners are secured around the reinforcement R, the hook portion 7a being mounted around the reinforcement R, e.g. as illustrated in FIG. 1c.
Herefter kan betonfladen udstøbes, og trådstykkerne 7 står herefter i det væsentlige vinkelret ud fra, dvs. lodret op fra, overfladen af den udstøbte flade. Umiddelbart efter udstøbningen af betonfladen er det herefter muligt at lægge isoleringen 9 i støbeformen, idet isoleringsplader 9 kan trykkes ned over de opretstående trådstykker 7. Det er således ikke længere nødvendigt at afvente, at betonen er hærdet før isoleringen fastgøres til betonelementet.Thereafter, the concrete surface can be cast and the wire pieces 7 are then substantially perpendicular from, i. vertically from above, the surface of the cast surface. Immediately after casting the concrete surface, it is then possible to lay the insulation 9 in the mold, insulating plates 9 can be pressed down over the upright threads 7. Thus, it is no longer necessary to wait for the concrete to harden before the insulation is attached to the concrete element.
Herefter påføres dybelhovedet 1, idet den aksiale boring 5, 6 gennem dybelhovedet 1 føres ned over trådstykket 7, hvorefter rørdelen 2’ og den tilspidsede del heraf 2” trykkes ned i isoleringsmaterialet 9.Subsequently, the dipping head 1 is applied, the axial bore 5, 6 passing through the dipping head 1 over the wire piece 7, after which the pipe part 2 'and the tapered part thereof 2' are pressed into the insulating material 9.
Derefter føres rørstykket 8 ned omkring trådstykket 7, og placeres i boringen 5 i rørdelen 2’, som vist på fig. 2. Som det ses på fig. 2, rager rørstykket 8 ud af udboringen 5 i rørdelen 2, hvilket muliggør, at et værktøj B (se fig. 6b) kan gribe om rørstykket, se fig. 6c-d. Derefter klippes trådstykket 7, om nødvendigt, af i en passende afstand over rørstykket 8. Det tilbageværende trådstykke ombukkes herefter omkring rørstykket 8 med værktøjet A som indikeret med pilene A’ (fig, 6c), så det danner en krog 7b eller lignende, f.eks. som vist på fig. 3 og 6c. Dermed fastholdes rørstykket 8 på trådstykket 7 og værktøjet A fjernes som indikeret med pilene A” og A’”.Then the pipe piece 8 is led down around the wire piece 7 and placed in the bore 5 in the pipe part 2 ', as shown in FIG. 2. As seen in FIG. 2, the pipe piece 8 protrudes from the bore 5 in the pipe part 2, which allows a tool B (see Fig. 6b) to grip the pipe piece, see fig. 6c-d. Then, if necessary, the wire piece 7 is cut off at a suitable distance above the pipe piece 8. The remaining wire piece is then wrapped around the pipe piece 8 with the tool A as indicated by the arrows A '(Fig. 6c) to form a hook 7b or the like, f .g. as shown in FIG. 3 and 6c. Thus, the pipe piece 8 is held on the wire piece 7 and the tool A is removed as indicated by arrows A "and A" ".
For at opnå en forspænding af trådstykket 7, og derved opnå en fastholdelse af dybelhovedet på trådstykket 7, og dermed fastholdelse af isoleringen 9 på betonelementet, bliver rørstykket 8 og det medfølgende trådstykke 7 bukket ud gennem slidsen 3 i dybelhovedet ved at vippe værktøjet B, som indikeret med pilene B’ på fig. 6d, og efterfølgende presset ned i den omgivende isolering 9, som vist på fig. 4 og som illustreret på fig. 6d. For at opnå den korrekte forspænding af trådstykket 7, er slidsen 3 i dybelhovedet udformet med en forankringsflade 4 i form af et fremspring i bunden af rørdelens slids 3, for at sikre at rørstykket 8 og det medfølgende trådstykke 7 bukker nøjagtigt ud for forankringsfladen 4 i slidsen 3. Til slut fjernes værktøjet B, som indikeret med pilene B” og B’” på fig. 6d.In order to obtain a prestressing of the wire piece 7, thereby obtaining the dip head retention on the wire piece 7, and thus retaining the insulation 9 on the concrete element, the pipe piece 8 and the accompanying wire piece 7 are bent out through the slot 3 in the dip head by tilting the tool B, as indicated by arrows B 'in FIG. 6d, and subsequently pressed into the surrounding insulation 9, as shown in FIG. 4 and as illustrated in FIG. 6d. In order to obtain the correct prestressing of the thread piece 7, the slit 3 in the double head is formed with an anchoring surface 4 in the form of a protrusion at the bottom of the slit 3 of the pipe part, to ensure that the pipe piece 8 and the accompanying thread piece 7 bend precisely to the anchoring surface 4 in slot 3. Finally, tool B is removed, as indicated by arrows B "and B" on fig. 6d.
Rørstykket 8 kan eventuelt udelades, hvis der i stedet anvendes et værktøj, der støtter trådstykket 7 i hele udboringens 5 længde, så tråden 7 bukker præcist over forankringsfladen 4 i bunden af slidsen, når tråden 7 bukkes ned i det omgivende isoleringsmateriale 9.Optionally, the pipe piece 8 may be omitted if a tool is used instead to support the wire piece 7 throughout the length of the bore 5 so that the wire 7 bends precisely over the anchoring surface 4 at the bottom of the slot as the wire 7 is bent into the surrounding insulating material 9.
Nedbukningen i isoleringen 9 sikrer således både den nødvendige forspænding af tråden, der dels sikrer fastholdelse af dybelhovedet på trådstykket 7, og dels forhindrer dybelhovedet i at rotere på tråden. Derved sikres den ønskede fastgørelse af isoleringen 9 på betonelementet, og samtidigt hermed undgås kuldebroer mellem betonfladen og isoleringens 9 modsatte side i områderne omkring dyblerne.The deflection in the insulation 9 thus ensures both the necessary biasing of the thread, which partly ensures the retention of the dip head on the thread piece 7 and partly prevents the dip head from rotating on the thread. This ensures the desired attachment of the insulation 9 to the concrete element, while avoiding cold bridges between the concrete surface and the opposite side of the insulation 9 in the areas around the dips.
Ved nedbukningen af trådstykket 7 trækkes forankringsskiven 1 lidt ned i isoleringsmaterialet, således at forankringsskivens 1 øvre sideflade er i det væsentlige i plan med isoleringens overside, samtidigt med at tråden forspændes yderligere.In the bending of the wire piece 7, the anchoring disc 1 is slightly lowered in the insulating material, so that the upper side surface of the anchoring disc 1 is substantially flush with the upper side of the insulation, while at the same time further tightening the thread.
For yderligere at reducere risikoen for at der opstår en kuldebro ved dyblerne, kan der afslutningsvis lægges en isoleringsstrimmel 10, f.eks. et stykke fugebagstop, i den dannede åbning i isoleringen 9, hvilket er vist på fig. 5. Herefter er isoleringen 9 monteret på det udstøbte og endnu våde betonelement. Samtidigt med at betonelementet hærder, kan overfladen af betonelementet færdiggøres, f.eks. ved påførelse af et eller flere pudslag. Forankringsskivens 1 fordybninger og/eller åbninger 1” sikrer, at sådanne pudslag også kan vedhæfte på forankringsskiven 1. Fremgangsmåden og dybelsystemet gør det således muligt fremstille et isoleret betonelement, hvor de arbejdsprocesser, der skal udføres i fremstillingen kan foregå i løbet af den kortest mulige tid, og med færrest mulige pauser i produktionen.In order to further reduce the risk of a cold bridge at the dips, an insulating strip 10, e.g. a piece of joint backstop, in the formed opening in the insulation 9, which is shown in FIG. 5. Then the insulation 9 is mounted on the cast and still wet concrete element. At the same time as the concrete element hardens, the surface of the concrete element can be finalized, e.g. by applying one or more plaster strokes. The recesses and / or openings 1 ”of the anchor washer 1” ensure that such plaster can also adhere to the anchor washer 1. The method and the dip system thus make it possible to produce an insulated concrete element, where the work processes to be carried out in the manufacture can take place in the shortest possible time. time, and with as few breaks as possible in production.
Dybelsystemet er særligt egnet til fastgørelse af isoleringsmaterialer i pladeform. Egnede isoleringsmaterialer, er i denne forbindelse især mineraluld, f.eks. glas- eller stenuld, foamglas, plastbaserede isoleringsmaterialer, herunder polystyren (PS), polyurethan (PU eller PUR) eller polyisocyanurat (PIR) og/eller kombinationer heraf.The dip system is particularly suitable for fixing insulating materials in plate form. Suitable insulating materials are in this connection especially mineral wool, e.g. glass or stone wool, foam glass, plastic-based insulating materials, including polystyrene (PS), polyurethane (PU or PUR) or polyisocyanurate (PIR) and / or combinations thereof.
