Abstract
Description
447 280 2 vögen vilket inneburit att man antingen tvingats välja relativt dyra isolationsmaterial med god vörmeisolationsförmåga eller billigare med sömre isolationsförmåga men som måste läggas i tjockare skikt. 447 280 2 the road, which has meant that one has either been forced to choose relatively expensive insulation materials with good thermal insulation capacity or cheaper ones with poorer insulation capacity but which must be laid in thicker layers.
Syftet med föreliggande uppfinning ör att åstadkomma en vürmeiso- lerad vögbana dör vörmeisolationen kan utgöras av ett billigt material med relativt låg hållfasthet. Syftet har uppnåtts genom uppfinningen som innefattar ett eller flera lastbörande organ samt vörmeisolering och som könnetecknas av att det lastbörande organet utgörs av ett på markunderlaget stående och mot marken öppet hölje som sträcker sig i vögens löngdriktning och vilket ör fyllt med en vörmeisolering. Genom att höljet tar upp och fördelar belastningen från fordonen kan en vörmeisolation med relativt hög isolationsförmåga men relativt låg hållfasthet användas.The object of the present invention is to provide a heat-insulated road surface where the heat insulation can be constituted by an inexpensive material with relatively low strength. The object has been achieved by the invention which comprises one or more load-bearing members and thermal insulation and which is characterized by the load-bearing member consisting of a casing standing on the ground and open to the ground which extends in the longitudinal direction of the carriage and which is filled with thermal insulation. Because the housing absorbs and distributes the load from the vehicles, a thermal insulation with a relatively high insulation capacity but relatively low strength can be used.
Ett annat syfte med uppfinningen ör att medge användning av sk. porbetong, i synnerhet på plats tillverkad skumbetong, som värme- isolation. Skumbetong tillverkas genom att piska in luft i en ce- ment-vattenblandning i vilken tillsatts ett luftporbildande medel.Another object of the invention is to allow the use of so-called aerated concrete, especially foam concrete produced on site, as thermal insulation. Foam concrete is made by whipping air into a cement-water mixture in which an air-pore-forming agent has been added.
Genom att piska in mer luft minskar man betongens densitet och håll- fasthet men ökar dess vürmeisolationsförmåga. Höljet utgör härvid en kvarsittande gjutform för vörmeisolationen efter det att denna hördats till fast form utöver det att det upptar belastning från fordon på vögen. Uppfinningen beskrivs nedan i form av ett ut- föringsexempel i anslutning till bifogade figurer.By whipping in more air, you reduce the density and strength of the concrete but increase its heat-insulating ability. The casing here constitutes a fixed mold for the thermal insulation after it has been sounded to a solid form in addition to absorbing load from vehicles on the road. The invention is described below in the form of an exemplary embodiment in connection with the accompanying figures.
Figur 1 visar ett tvärsnitt genom en vügbana.Figure 1 shows a cross section through a cradle path.
Figur 2 visar två höljen anordnade på stödsocklar.Figure 2 shows two housings arranged on support bases.
Vögbanan enligt figur 1 består av två i vügens löngdríktning,ut- med varandra anordnade höljen 1, respektive innefattande en i huvudsak horisontellt anordnad toppdel 2 samt två mot toppdelen svagt lutande sidodelar 3. Höljets l samtliga delar utgörs av korrugerad stålplåt anordnad med sina åsar och kanaler i huvud- sak vinkelrätt mot vögens löngdriktning. Höljets 1 sidodelar 3 är placerade på stödsocklar 4 utmed sidodelarnas 3 nedre kant.The roadway according to Figure 1 consists of two longitudinal directions of the road, mutually arranged casings 1, respectively comprising a substantially horizontally arranged top part 2 and two side parts 3 sloping slightly towards the top part. The parts of the casing 1 consist of corrugated steel plate arranged with their ridges and channels substantially perpendicular to the longitudinal direction of the road. The side parts 3 of the housing 1 are placed on support bases 4 along the lower edge of the side parts 3.
»IN 447 280 Stödsocklarna 4 ör i sin tur placerade på markunderlaget som av- jümnats För ändamålet. Vid vögbanans mitt utnyttjas en gemensam stödsockel för de mot varandra stående sidodelarna 3. Stödfyllnad 5 är påfylld mot samtliga sidodelar 3 och håller höljet 1 på plats under påfyllning av en vörmeísolation 6 som tillföres genom öpp- ningar i toppdelen 2 men som ej visas i figurerna. En slitbana 7 är slutligen anbringad på toppdelarna 2 samt på stödfyllningen mellan de båda míttre sidodelarna 3. Slitbanan kan t ex utgöras av asfalt. Stödfyllningen mellan de båda mittre sídodelarna kan lik- som vörmeísolationen 6 utgöras av skumbetong.»IN 447 280 The support plinths 4 are in turn placed on the ground surface that has been leveled For the purpose. At the middle of the roadway a common support base is used for the opposite side parts 3. Support filling 5 is filled against all side parts 3 and holds the housing 1 in place while filling a thermal insulation 6 which is supplied through openings in the top part 2 but not shown in the figures. . A tread 7 is finally applied to the top parts 2 and to the support filling between the two central side parts 3. The tread can for instance consist of asphalt. The support filling between the two middle side parts can, like the thermal insulation 6, consist of foam concrete.
