Abstract

The invention concerns a form attachment to be used for casting electricity boxes in wall or ceiling elements. The form attachment consists of a cover 1 intended to be secured on the mould, and a bolt 2 which is integral with the cover and is provided with a spike channel 5 and threads. When the cover 1 is secured on the mould, the box 10 is engaged on the bolt 2 and locked with a nut 8 on the underside of the box 10. After casting, the form is dismantled and the attachment is unthreaded from the box 10, the nut 8 remaining under the box and sealing off the hole in its base. <IMAGE>

Description

467 ses g “ Figurerna 1 och 2 visar ett formfäste enligt uppfinningen, i en skuren sidovy respektive i en vy sedd rakt uppifrån, medan fig 3 visar formfästet med en monterad elektrisk dosa. 467 is seen g “Figures 1 and 2 show a mold bracket according to the invention, in a cut side view and in a view seen straight from above, respectively, while Fig. 3 shows the mold bracket with a mounted electrical box.

I figurerna betecknar l ett lock med en integrerad bult 2 och en fästplugg 3. 4 och 6 betecknar tätningskanter på locket, 5 en spikkanal, 7 vingar, 8 en mutter, 9 en spik och 10 konturen av en elektrisk dosa.In the figures, 1 denotes a lid with an integrated bolt 2 and a fastening plug 3. 4 and 6 denote sealing edges on the lid, 5 a nail channel, 7 wings, 8 a nut, 9 a nail and the contour of an electrical box.

Formfästet enligt uppfinningen fungerar på följande sätt: Fästet i sin helhet, med undantag för muttern 8, fästs vid gjutformen. I det fall denna är av stål, införs fästpluggen 3 i ett hàl i formen och en spik 9 slås in genom spikkanalen 5 fràn fästets baksida. Om gjutformen däremot är en trä, knips fästpluggen 3 av och spiken 9 slås in i trävirket. Sedan fästet fixerats pà gjutformen, görs ett hål i botten på dosan så att den kan träs pà bulten 2, tills dosans öppning kommer till anliggning mot locket l, vars form är anpassad till dosöppningen. För att säkerställa tätningen och samtidigt styra dosan till rätt läge, är locket 1 på undersidan försett med en runt om gående kant 4, som kommer till anliggning mot dosöppningens innerkant. Muttern 8 skruvas därefter pà bulten 2 och spännes fast mot dosbotten så att dosans öppning tätande pressas mot locket 1. Muttern 8 är utformad så att den avtätar hålet i dosbotten och kan även utgöras av en kupolmutter, som då innesluter spikhuvudet.The mold bracket according to the invention works as follows: The bracket in its entirety, with the exception of the nut 8, is fastened to the mold. In case this is made of steel, the fastening plug 3 is inserted into a hole in the mold and a nail 9 is driven in through the nail channel 5 from the back of the bracket. If, on the other hand, the mold is a wood, the fastening plug 3 is cut off and the nail 9 is driven into the wood. After the bracket has been fixed to the mold, a hole is made in the bottom of the box so that it can be threaded onto the bolt 2, until the opening of the box comes into contact with the lid 1, the shape of which is adapted to the can opening. To ensure the seal and at the same time guide the can to the correct position, the lid 1 on the underside is provided with a circumferential edge 4, which comes into abutment against the inner edge of the can opening. The nut 8 is then screwed onto the bolt 2 and clamped against the can bottom so that the opening of the can is pressed sealingly against the lid 1. The nut 8 is designed so that it seals the hole in the can bottom and can also consist of a dome nut, which then encloses the nail head.

Tack vare inspänningen med muttern mot dosbotten erhålles en mycket säker fasthållning av dosan och en helt tät anslutning mellan dosöppning och lock.Thanks to the clamping with the nut against the dose bottom, a very secure holding of the box and a completely tight connection between the dose opening and the lid is obtained.

Sedan gjutningen slutförts borttas formen och eftersom in- fästningen av locket i formen utgörs av ett spikförband, sker detta jämförelsevis lätt. Sammanhàllningen av fäste och dosa däremot sker med hjälp av ett starkare skruvförband. Därefter demonteras formfästet fràn dosan genom vridning med hjälp av vingarna 7 i locket. Muttern 8 blir kvar inne i betongen och avtätar hålet i dosbotten. För att säkerställa en god isoler- vv - » u. v» -5 467 563 ing är muttern 8 lämpligen försedd med en integrerad bricka med större diameter pà sin mot dosbotten vända sida.After the casting has been completed, the mold is removed and since the attachment of the lid to the mold consists of a nail joint, this is comparatively easy. The fastening of the bracket and box, on the other hand, takes place with the help of a stronger screw connection. Then the mold bracket is disassembled from the box by turning by means of the wings 7 in the lid. The nut 8 remains inside the concrete and seals the hole in the dose base. To ensure good insulating vv - »u. V» -5 467 563 ing, the nut 8 is suitably provided with an integrated washer of larger diameter on its side facing the dose base.

Dosan är nu ren och klar för ledningsdragning. Sedan denna slutförts kan, om så önskas, fästet åter skruvas i för skydd av dosan tills den slutliga monteringen av strömbrytare eller dylikt skall ske.The box is now clean and ready for wiring. After this has been completed, if desired, the bracket can be screwed in again to protect the box until the final installation of a switch or the like is to take place.

Enligt en alternativ metod förmonteras fäste och dosa, varef- ter hela enheten fästs pà gjutformen. Vid detta förfarande krävs dock en mutter med genomgående hål för att möjliggöra spikningen.According to an alternative method, the bracket and box are pre-assembled, after which the entire unit is attached to the mold. In this procedure, however, a nut with through holes is required to enable nailing.

För att förhindra att lockets l försänkning fylls med material under gjutningen, vilket skulle kunna försvåra utskruvningen, finns en runt om gående kant 6 på lockets översida, som säker- ställer tätningen mot gjutformen.To prevent the recess of the lid 1 from being filled with material during casting, which could make it difficult to unscrew, there is a circumferential edge 6 on the upper side of the lid, which ensures the seal against the mold.
