Den foreliggende frembringelse angår en støbeleder af den i indledningen til krav 1 angivne art.The present invention relates to a casting conductor of the kind specified in the preamble of claim 1.

Ved fremstilling af betongulve eller tilsvarende større plane betonoverflader anvendes der såkaldte gulvledere, der består af præfabrikerede støbeledere med en topdel, hvorpå en bjælkevibrator kan være glidende understøttet i forbindelse med udstøbning af de gulvfelter, der dannes mellem gulvledeme. Disse monteres og/eller punktunderstøttes i langstrakte baner eller felter på komprimeret, afrettet underlag af sand/grus eller ovenpå et egnet isoleringsmateriale. Gulvledeme forbliver i gulvet som en permanent forskalling, der afgrænser støbebaneme i sideretningen.In the manufacture of concrete floors or similarly large flat concrete surfaces, so-called floor conductors are used, which consist of prefabricated casting conductors with a top part, on which a beam vibrator can be slidably supported in connection with the casting of the floor panels formed between the floor joints. These are mounted and / or point supported in elongated webs or fields on compressed, sanded / gravel or on a suitable insulating material. The floor joints remain in the floor as a permanent formwork, defining the lateral moldings.

Alternativt er det kendt at anvende en væsentlig kraftigere genbrugsleder eller forskalling, der er fremstillet af stål og aluminium, og som fjernes igen efter støbning af gulvfelter, dvs. inden de mellemliggende gulvfelter støbes mod de forbindelsesprofiler, som den afmonterede genbrugsgulvleder har givet sidekanteme af gulvfelteme.Alternatively, it is known to use a significantly more powerful recycled conductor or formwork made of steel and aluminum, which is removed again after casting of floor panels, ie. before casting the intermediate floor panels against the connection profiles provided by the dismantled recycled floor conductor side edges of the floor panels.

Betonstøbeledere af stål eller med ståltopliste kendes eksempelvis fra DK brugsmodelregistrering nr. 9600236 og 9300270, der er en videreudvikling af de gennem mange år anvendte betonstøbeledere, der eksempelvis kendes fra Dansk mønsterregistre-ring nr. 0401 1992.Concrete casting conductors made of steel or with steel topping list are known, for example, from DK utility model registration no. 9600236 and 9300270, which is a further development of the concrete casting conductors used for many years, for example known from Danish pattern registration no. 0401 1992.

Der har imidlertid vist sig nogle problemer eller ulemper ved anvendelsen af de nævnte kendte gulvledere af stål eller af beton med eller uden ståltopliste, hvoraf det største problem er de meget dyre transportomkostninger på grund af den store egenvægt af betonstøbeledere. Desuden er det et problem, at betonstøbeledere ofte knækker under transporten, hvis de ikke er korrekt understøttet.However, some problems or disadvantages have been found in the use of the aforementioned known steel or concrete floor conductors with or without steel top molding, the main problem being the very expensive transport costs due to the large self-weight of concrete casting conductors. In addition, it is a problem that concrete casting conductors often crack during transport if they are not properly supported.

På denne baggrund er det formålet med frembringelsen at angive en helt ny type og forbedret gulvleder af den indledningsvis nævnte type, hvilken støbeleder ved enkle foranstaltninger gør det muligt at undgå de forannævnte ulemper.Against this background, the object of the invention is to indicate a completely new type and improved floor conductor of the type mentioned in the introduction, which by simple measures allows the casting member to avoid the aforementioned disadvantages.

Gulvlederen ifølge frembringelsen er kendetegnet ved, at nævnte foddel udgøres af en langsgående lodret kantdel, og at nævnte forkrøpninger af kropdelen udgøres af overvejende zig-zag-profilering, således at forkrøpningerne i brugssituationen danner feder/not-låsesamlinger ved støbelederens respektive sider mellem tilstødende betonplader. Ved enkle foranstaltninger opnås herved en helt ny type støbeleder, hvorved de nævnte ulemper ikke forekommer, idet en støbeleder fremstillet helt af tynd, f.eks. galvaniseret stålplade har en betydelig mindre egenvægt end en tilsvarende støbeleder med en fod- og kropdel af beton. Desuden er en støbeleder fremstillet af profileret stålplade temmelig robust, dvs. at den ikke er udsat for knækskader - som tilfældet ville være ved en tilsvarende støbeleder af beton.The floor conductor according to the invention is characterized in that said foot part is made up of a longitudinal vertical edge part and said crevices of the body part are predominantly zig-zag profiling, so that in the use situation the creases form spring / groove lock joints at the respective sides of the casting member between adjacent concrete pads. . By simple measures a whole new type of molding conductor is thereby obtained, whereby the disadvantages mentioned do not occur, as a molding conductor made entirely of thin, e.g. galvanized steel sheet has a considerably smaller intrinsic weight than a similar casting conductor with a concrete foot and body part. Furthermore, a casting conductor made of profiled steel sheet is rather robust, ie. that it is not prone to cracking - as would be the case with a similar concrete conductor.

Mere generelt har bølgelederen ifølge frembringelsen følgende fordele: - er let at pakke (sammenstable) for forsendelse - er mere ensartet (uanset størrelsen) - er nem at fremstille (bukkes eller valses) - har mindre materialeforbrug - er mindre udsat for at blive skæv - er relativ let (i forhold til stivhed) - er let at montereMore generally, according to the production, the waveguide has the following advantages: - is easy to pack (stackable) for shipping - is more uniform (no matter the size) - is easy to manufacture (bends or rolls) - has less material consumption - is less prone to warping - is relatively light (relative to stiffness) - is easy to assemble

Fortrinsvis er støbelederen ifølge frembringelsen desuden således udformet, at dens foddel, kropdel og øvre kantliste eventuelt er udformet med huller eller åbninger, der er indrettet til gennemføring af eventuelle i hovedsagen vandrette armeringsjem.Preferably, the casting conductor according to the invention is furthermore designed such that its base, body part and upper edge strip are optionally formed with holes or openings arranged for carrying out any generally horizontal reinforcement inserts.

Frembringelsen angår tillige en montageholder til brug ved montering af støbelederen ifølge frembringelsen og omfattende en holdedel for nævnte foddel af støbelederen, hvilken montageholder er kendetegnet ved, at holdedelen har overvejende vandret forløb og har en i hovedsagen lodret slidse til optagelse af foddelen, og at holdedelen desuden er indrettet til at kunne fikseres i variabel højde i forhold til en foddel af montageholderen.The invention also relates to a mounting bracket for use in mounting the molding guide according to the manufacture and comprising a holding part for said foot part of the molding guide, the mounting bracket being characterized in that the holding part has a predominantly horizontal course and has a substantially vertical slot for receiving the foot part, and that the holding part in addition, it is arranged to be fixed at variable height in relation to a foot part of the mounting bracket.

Hensigsmæssigt er montageholder ifølge frembringelsen udformet således, at nævnte foddel af montageholderen omfatter et første par af i hovedsagen lodrette opstandere, der mellem sig danner en i hovedsagen lodret styreslidse, hvori en styredel af holdedelen indgriber, samt et andet opstanderpar i afstand fra første opstanderpar, hvilket andet opstanderpar mellem sig danner en anden styreslidse, der forløber parallelt med førstnævnte styreslidse, og som er indrettet til at fastspænde holddelen, når denne er indstillet i højden ved hjælp af en fortrinsvis pladeformet kile, der fra siden indføres mellem første og andet opstanderpar.Conveniently, the mounting bracket according to the invention is designed such that said foot portion of the mounting bracket comprises a first pair of substantially vertical uprights forming between them a substantially vertical guide slot in which a guide portion of the holding portion engages, and a second upright pair spaced from the first upright pair, said second upright pair forming a second guide slot extending parallel to said first guide slot and adapted to clamp the holding member when adjusted in height by a preferably plate-shaped wedge inserted laterally between first and second upright pairs.

Med særlig fordel kan montageholder ifølge frembringelsen desuden være udformet således, at nævnte fortrinsvis pladeformede kile har flere fortrinsvis indbyrdes parallelle kileflader, der tillader højdeindstilling i flere trin, idet nævnte holdedel omfatter en ba-gudragende dele, f.eks. en vandret bolt, der samvirker med nævnte kileflader.With particular advantage, the mounting bracket according to the invention can furthermore be designed such that said preferably plate-shaped wedges have several preferably parallel wedge surfaces which permit height adjustment in several steps, said holding part comprising a bed-supporting parts, e.g. a horizontal bolt cooperating with said wedge surfaces.

En foretrukken montageholder 22 er vist i fig. 12. Montageholderen 22 omfatter en basisplade 24, hvorpå en lodret opstander 26 af firkantrør er fastsvejst. På opstanderen 26 er teleskopisk lejret en ligeledes rørformet styredel 27 for en vandret holdedel 28 med en lodret slidse 30, hvori en nedre foddel 4 af bølgelederen 2 kan fastspændes ved hjælp af en vingebolt 32. Som det desuden fremgår af fig. 13 er styredelen 27 for holdedelen 28 indrettet til at højdejusteres ved hjælp af en udragende del 34 f.eks. i form af en stilleskrue 36. Selve højdejusteringen af holdedelen 28 foregår ved hjælp af en pladekile 38, der ved bagsiden af styredelen 27 (modsat holdedelen 28) fra siden kan indføres i et styrespor 37 på foddelen 24. Pladekilen 38 omfatter to fortrinsvis parallelle kilekanter, nemlig en nedre kilekant 40 og en øvre kilekant 42, der kan samvirke med stilleskruen 36, hvilket gør det muligt ad to gange at opnå maksimal højdejustering, idet styredelen 27 for holdedelen 28 i første omgang højdejusteres maksimalt ved hjælp af den nedre kilekant 40 - efterfølgende evt. efter midlertidig fiksering - kan styredelen 27 kiles endnu højere op ved hjælp af den øvre kilekant 42.A preferred mounting bracket 22 is shown in FIG.
