Den foreliggende frembringelse angår en indretning til midlertidig fiksering af PEX-installationsrør og af den i indledningen til krav 1 angivne art.The present invention relates to a device for the temporary fixing of PEX installation pipes and of the kind specified in the preamble of claim 1.

Ved fremstilling af moderne vand- og varmeinstallationer anvendes PEX-rør, der er et dobbelt installationsrør (rør-i-rør), hvor et ydre korrugeret plastrør udgør en kappe for selve installationsrøret, der ligeledes er af plastik, f.eks. PEL-rør. Fra en central fordeler eller manifold fremføres til hver brugsgenstand, f.eks. en radiator, PEX-rør både som tilførsels- og returrør på en sådan måde, at hvert af inderrørene skal kunne udskiftes, idet det korrugerede kapperør placeres i isolationslaget under gulvkonstruktionen og indstøbes i gulvet i fyr- og vådrum, hvor nævnte fordeler eller manifold ofte er placeret i forbindelse med den resterende vand- eller varmeinstallation.In the manufacture of modern water and heating installations PEX pipes are used, which is a double installation pipe (pipe-in-pipe), where an outer corrugated plastic pipe forms a sheath for the installation pipe itself, which is also of plastic, e.g. PEL-tubes. From a central distributor or manifold is conveyed to each utility item, e.g. a radiator, PEX pipes both as supply and return pipes in such a way that each of the inner pipes must be replaceable, the corrugated casing pipe being placed in the insulation layer under the floor construction and embedded in the floor in boiler and wet rooms, where said advantages or manifold are often is located in connection with the remaining water or heating installation.

Hvis der forekommer PEX-rørstrækninger på mere end 10-12 meter eller med mange sving, kan det desuden være nødvendigt at indskyde en fordeler eller manifold et passende sted på PEX-rørstraekningen, f.eks. i bunden af et indbygget skab.In addition, if PEX pipe stretches of more than 10-12 meters or with many turns occur, it may be necessary to insert a manifold or manifold at an appropriate location on the PEX pipe section, e.g. at the bottom of a built-in closet.

Enderne af de fleksible PEX-installationsrør er oftest vanskelige at styre, hvorfor der findes forskellige holdeindretninger, der er beregnet til midlertidig fiksering af enderne af nævnte udvendige kapperør af PEX-installationsrør. En kendt holdeindretning af denne type består af plastkassetter, der hver er indrettet til at fiksere et rørpar, og som kan sammembygges til fiksering af det ønskede antal rørpar. I praksis er denne kendte holder imidlertid kostbar at anvende, fordi den faststøbes i gulvet og derfor ikke kan genanvendes.The ends of the flexible PEX installation pipes are most often difficult to control, which is why there are various holding devices designed to temporarily fix the ends of said outer casing pipes of PEX installation pipes. A known holding device of this type consists of plastic cartridges, each arranged to fix a pair of tubes and which can be assembled to fix the desired number of tubes. In practice, however, this known holder is expensive to use because it is embedded in the floor and therefore cannot be reused.

Frembringelsen har til formål at angive en forbedret indretning til midlertidig fiksering af PEX-installationsrør, og som gør det lettere at opnå en pænere PEX-rørsinstallation, hvilken fikseringsindretning er indrettet til at genbruges, idet den fortrinsvis er fremstillet af stål.The object of the invention is to provide an improved device for the temporary fixing of PEX installation pipes, which makes it easier to obtain a nicer PEX pipe installation, which fixing device is arranged to be reused, preferably made of steel.

Fixseringsindretningen ifølge frembringelsen er kendetegnet ved, at indretningen omfatter rækker af indbyrdes parallelle, rørformede holdemuffer, der hver er indrettet til at optage og fiksere en endedel af et PEX-rør, og som er arrangeret med en indbyrdes 2 DK 97 00243 U3 akseafstand, der er tilpasset en fordeler eller en manifold, og at indretningen omfatter organer, der er indrettet til at fastgøre indretningen i bestemt position i forhold til en kommende bygningsdel, f.eks. i undergrunden, eller til en eksisterende bygningsdel, f.eks. en mur eller en væg. Ved hjælp af enkle foranstaltninger opnås herved en forbedret fixseringsindretning af den indledningsvis nævnte art, der gør det lettere at opnå en pæn PEX-rørinstallation.The fixing device according to the invention is characterized in that the device comprises rows of mutually parallel tubular holding sleeves, each arranged to receive and fix an end part of a PEX pipe, and which are arranged with a spacing between them. is adapted to a manifold or manifold, and that the device comprises means arranged to secure the device in a certain position with respect to an upcoming building part, e.g. in the underground, or to an existing building part, e.g. a wall or wall. By means of simple measures an improved fixing device of the kind mentioned above is hereby obtained, which makes it easier to obtain a neat PEX pipe installation.

Hensigtsmæssigt kan fikseringsindretningen ifølge frembringelsen være således udformet, at nævnte rørformede holdemuffer er arrangeret i et holdelegeme, der fortrinsvis er fremstillet af stålplade, og som omfatter en til lodret placering beregnet basisplade og to derfra vinkelret udstående, indbyrdes parallelle holdeplader, der hver er udformet med rækker af indbyrdes huller, hvori holdemuffeme er fastgjorte, idet holdemuffeme består af rør med en større længde end afstanden mellem holdeplademe. Dvs. at fikseringsindretningen umiddelbart kan genanvendes.Conveniently, the fixing device according to the invention may be designed such that said tubular holding sleeve is arranged in a holding body, preferably made of steel plate, comprising a base plate calculated for vertical position and two perpendicularly parallel, mutually parallel holding plates, each formed with rows of mutual holes in which the holding sleeves are secured, the holding sleeves being made of tubes of a greater length than the distance between the holding plates. Ie that the fuser can be reused immediately.

Indretningen ifølge frembringelsen kan enten være således udformet, at den er indrettet til at fastgøres i undergrunden, idet den omfatter fortrinsvis rørformede jordspyd, der modsat nævnte basisplade er fastsvejst til kantdele af nævnte holdeplader; eller indretningen kan være indrettet til at fastgøres på en væg, hvorfor basispladen er udformet med befæstigelseshuller. Fortrinsvis kan indretningen være indrettet med både nævnte befæstigelseshuller i basispladen og nævnte jordspyd, således at en og samme indretning valgfrit enten kan fikseres på eksisterende mur eller væg (f.eks. ved renoveringsarbejder, hvor der skal støbes nyt gulv over eksisterende) eller kan fikseres i undergrunden (navnlig ved nybyggeri).The device according to the invention can either be designed to be fixed to the subsoil, preferably comprising tubular earth spears, which are opposite to said base plate, welded to edge portions of said holding plates; or the device may be arranged to be secured to a wall, therefore the base plate is formed with mounting holes. Preferably, the device may be provided with both said fixing holes in the base plate and said earth spear, so that one and the same device can optionally be fixed either to existing wall or wall (for example, for renovation work where new flooring is to be cast over existing) or can be fixed. in the underground (especially for new construction).

Med henblik på at gøre det lettere at komme til at montere fordelere eller manifolde, kan indretningen med fordel være udformet således, at nævnte rørformede holdemuffer i de respektive rækker fortrinsvis er indbyrdes forskudt.In order to make it easier to mount distributors or manifolds, the device may advantageously be designed such that said tubular holding sleeves in the respective rows are preferably displaced from one another.

Frembringelsen forklares nærmere i forbindelse med tegningen, der viser en foretrukken udførelsesform for en fikseringsindretning ifølge frembringelsen 3 DK 97 00243 U3The invention is explained in more detail in connection with the drawing, which shows a preferred embodiment of a fixing device according to the invention 3 DK 97 00243 U3

Den viste fikseringsindretning 2 er fremstillet af stålplade og stålrør, idet et holdelegeme 4 omfatter en basisplade 6, der er beregnet til lodret placering enten ved fastgørelse ved hjælp af befæstigelseshuller 8 direkte til en væg eller mur eller ved fiksering i undergrunden ved hjælp af jordspyd 10 i en position langs med en kommende mur eller væg. Fra over- og undersidekanter af basispladen 6 er udbukket indbyrdes parallelle holdeplader 12, der er indrettet til vandret placering, og som er udformet med rækker af ud for hinanden placerede huller 14, hvori er fastgjort rørformede holdemuffer 16, der er lidt længere end den indbyrdes afstand mellem holdeplademe 12. Holdemuffeme 16 er fastsvejst til holdeplademe 12, idet de enkelte rækker af holdemuffer 16 er indbyrdes forskudt, således at montering af fordelere eller manifolde lettes.The fixing device 2 shown is made of steel plate and steel tubes, a holding member 4 comprising a base plate 6 intended for vertical placement either by fixing by means of mounting holes 8 directly to a wall or wall or by fixing in the underground by means of earth spears 10 in a position along with an upcoming wall or wall. From the top and bottom edges of the base plate 6 are projected parallel parallel holding plates 12, arranged for horizontal placement, which are formed with rows of spaced apart holes 14, in which tubular holding sleeves 16 which are slightly longer than one another are fixed. spacing between the holding plates 12. The holding sleeves 16 are welded to the holding plates 12, the individual rows of holding sleeves 16 being offset from each other, so that mounting of distributors or manifolds is facilitated.

Fikseringsindretningen 2 ifølge opfindelsen kan findes i mange forskellige modeller eller typer, der er tilpasset gængse fordelere eller manifolde, dvs. hvor antallet af holdemuffer 16 og den indbyrdes akseafstand er tilpasset de respektive fordelere eller manifolde.The fixing device 2 according to the invention can be found in many different models or types adapted to conventional distributors or manifolds, ie. wherein the number of holding sleeves 16 and the spacing between them is adapted to the respective distributors or manifolds.

Eksempelvis anvendes den inderste række af seks stk. holdemuffer 16 ved den viste indretning 2 til fiksering af endedele af PEX-rør (rør-i-rør) til fremføring af koldt vand til aftapnings-positioner i et hus; medens den yderste forskudte række af seks stk. holdemuffer 16 eksempelvis repræsenterer endedele af PEX-rør til fremføring af varmt vand til samme aftapningspositioner.For example, the innermost row of six pieces is used. retaining sleeve 16 at the shown device 2 for fixing end portions of PEX (pipe-in-pipe) pipe for conveying cold water to drainage positions in a housing; while the outermost staggered row of six. holding sleeve 16, for example, represents end portions of PEX tubes for conveying hot water to the same tapping positions.

De viste jordspyd 10 består af stålrør, der opadtil er lukket ved hjælp af en kort massiv stålprop, der danner et slaghoved for neddrivning af jordspyd 10 i undergrunden ved hjælp af en tung hammer. Jordspydene 10 er fastsvejst til holdeplademe 12 og afstivet indbyrdes med en laskeplade 18.The earth spears 10 shown consist of steel pipes, which are closed upwards by means of a short solid steel plug, which forms a impact head for driving ground spears 10 into the underground by means of a heavy hammer. The ground spears 10 are welded to the holding plates 12 and stiffened with each other by a splash plate 18.

Når indretningen 2 skal anvendes til fiksering af endedele af PEX-rør ved renoverings-arbejder, hvor et eksisterende gulv forhindrer brug af jord spydene 10, vendes disse blot opad og basispladen 6 fastgøres i stedet til eksisterende væg eller mur.When the device 2 is to be used for fixing end portions of PEX pipes for renovation work, where an existing floor prevents the use of the ground spears 10, these are simply turned upwards and the base plate 6 is fixed instead to existing wall or wall.
