Opfindelsen angår et nyt let konstruktionselement, særligt beregnet til dørkonstruktioner i vogne.The invention relates to a new lightweight construction element, especially intended for carriage door structures.

De tekniske krav, der stilles til et let konstruktions-5 element, særligt til konstruktion af vogndøre, er af forskellig art. Ved siden af vægten, skal den være selvbærende og korrosionsbestandig og have en minimal dimensionsforandring også ved intensiv solbestråling. Det skal derudover være egnet til til at kunne forarbejdes til 10 stor-formatede og bukkede overflader.The technical requirements for a lightweight structural element, especially for the construction of carriage doors, are of different kinds. Alongside the weight, it must be self-supporting and corrosion resistant and have a minimal dimensional change even in intense solar radiation. In addition, it must be suitable for processing into 10 large-format and curved surfaces.

Opfindelsen har til formål at angive et nyt let konstruktionselement, der har ovenfor nævnte egenskaber.The invention has for its object to provide a new lightweight construction element having the above-mentioned properties.

Dette formål opnås ifølge opfindelsen ved et let konstruktionselement, der har de i patentkrav 1 givne ejen-15 dommeligheder.This object is achieved according to the invention by a lightweight construction element having the characteristics given in claim 1.

Som bærende kerne anvendes skumstofpiader af sejhærdet materiale, fortrinsvis anvendes PVC-skumstof med lukket cellestruktur, der har en rumvægt fra 70 til 90 kg/m^. Tykkelsen af disse kerner kan efter behov varieres. I en 20 foretrukken udførelsesform anvendes en tykkelse fra 20 til 35 mm, og fortrinsvis en tykkelse fra 25 til 38 mm.As the core, foam pads of toughened material are used, preferably closed cell structure PVC foam having a weight range from 70 to 90 kg / m 2. The thickness of these cores can be varied as needed. In a preferred embodiment, a thickness of 20 to 35 mm is used, and preferably a thickness of 25 to 38 mm.

Det elastiske materiale består i en foretrukken udførelsesform af blødgjort polyvinylchloridskum eller af poly-ethylenskum med en vægtfylde på 30 til 60 kg/m^, og især 25 benyttes polyethylenskum.The resilient material consists in a preferred embodiment of plasticized polyvinyl chloride foam or of polyethylene foam having a density of 30 to 60 kg / m 2, and in particular polyethylene foam is used.

Tykkelsen af det elastiske materiale kan efter behov varieres. Tykkelsen af det elastiske materiale er mindre end den bærende kernes. I en foretrukken udførelsesform er tykkelsen 8-10 mm.The thickness of the elastic material can be varied as required. The thickness of the resilient material is less than that of the supporting core. In a preferred embodiment, the thickness is 8-10 mm.

Mellem de nævnte skummaterialer er der anbragt et mellemlag, der ved hjælp af klæbning er fastgjort til de to overflader på de to skumstof kerner. Især anvendes en 5 to-komponentlim på polyurethanbasis eller epoxibasis.Between the said foam materials is an intermediate layer which is fixed by means of adhesive to the two surfaces of the two foam core. In particular, a 5-component polyurethane-based or epoxy-based adhesive is used.

I dette dobbeltsandwich-materiale er der udsparet hulrum til anbringelse af beslag, der er beregnet til optagning af og videreførelse af kræfter. Hulrummene må være udformet således, at beslagene kan sættes ind fra siden med 10 det sejhærdede materiale og ind i det elastiske materiale.In this double sandwich material, cavities are provided for the placement of fittings intended to absorb and carry forward forces. The cavities must be designed so that the fittings can be inserted from the side with the toughened material and into the elastic material.

I en foretrukken udførelsesform rager beslagene ind i det elastiske materiale, omkring halvdelen af dettes tykkelse.In a preferred embodiment, the fittings project into the elastic material, about half its thickness.

Beslagene tjener til optagelse og fordeling af kræfter. Sådanne beslag er f.eks. dørophængninger, låseaggregater, 15 tætningsbærere osv.The brackets serve to absorb and distribute forces. Such fittings are e.g. door hinges, lock assemblies, 15 seal carriers, etc.

Beslagene er i en foretrukken udførelsesform fremstillet af letmetal eller et ikke rustende stål.The fittings are in a preferred embodiment made of light metal or a non-rusting steel.

Dobbeltsandwich-elementet inklusive beslagene er på begge sider forsynet med et tætningslag. Dette tætningslag samt 20 mellemlaget mellem det sejhærdede og det elastiske materiale kan bestå af et fiberforstærket kunststof, f.eks. glasfiberforstærket, og har en tykkelse på 1-2,5 mm eller kan bestå af et metal med en tykkelse fra 0,8 til 1,5 mm, fortrinsvis bestående af aluminium. Disse dæklag er plet-25 mæssigt forbundet med dobbeltsandwich-elementet ved limning, f.eks. med en to-komponentlim. På grund af denne konstruktion er dæklaget svømmende forbundet med det fleksible materiale. I en foretrukken udførelsesform er dæklaget på det fleksible skumstofmateriale derudover 30 fastgjort til to ind til hianden liggende indbyrdes berøringskanter.The double sandwich element including the brackets is provided on both sides with a sealing layer. This sealing layer as well as the intermediate layer between the toughened and the elastic material may consist of a fiber-reinforced plastic, e.g. fiberglass reinforced, and having a thickness of 1-2.5 mm or may consist of a metal having a thickness of 0.8 to 1.5 mm, preferably consisting of aluminum. These cover layers are stainably connected to the double sandwich element by gluing, e.g. with a two-component adhesive. Because of this construction, the cover layer is swimmingly connected to the flexible material. In a preferred embodiment, the cover layer of the flexible foam material 30 is additionally attached to two adjacent contact edges.
