Abstract

Ett sandwichelement (11) för byggnadsändamål innefattar två färgbelagda plåtar (12,13)Iimmade till en kärna (14) av isolering. isoleringen består av ett antal bredvid varandrahoplagda stavar (15) och i anliggningen mellan stavarna ligger armeringsjärn (16,17)infällda i urfrästa kanaler (18,19) för att öka sandwichelementets motstånd mot yttre våld. A sandwich element (11) for building purposes comprises two color-coated plates (12, 13) glued to a core (14) of insulation. the insulation consists of a number of rods (15) stacked next to each other and in the abutment between the rods reinforcing bars (16,17) are recessed in milled-out channels (18,19) to increase the sandwich element's resistance to external force.

Description

537 543 Beskrivning av visat exempel på uppfinningen Figur 1 visar ett sandwichelement 11 som exempelvis kan vara 1200 mm brett och 6-12 meter långt. Figur 2 visar sandwichelementet i sektion. Det består av två yttre skikt 12,13 av varmförzinkad och färgbelagd stålplåt som är limmad till en kärna 14 av isolerings- material, exv mineralull eller expanderad polystyren. Kärnan består av ett antal längs- gående stavar 15 av isolering som är lagda tätt bredvid varandra och i anliggningsytan mellan två stavar ligger armeringsjärn 16,17. Description of the illustrated example of the invention Figure 1 shows a sandwich element 11 which can, for example, be 1200 mm wide and 6-12 meters long. Figure 2 shows the sandwich element in section. It consists of two outer layers 12,13 of hot-dip galvanized and color-coated steel sheet which is glued to a core 14 of insulating material, eg mineral wool or expanded polystyrene. The core consists of a number of longitudinal rods 15 of insulation which are laid close next to each other and in the contact surface between two rods there are reinforcing bars 16,17.

Figur 3 visar en av stavarna 15 med armeringsjärnen 16,17 i urfrästa spår 18,19 i ena ytan som ska anligga mot angränsande stav. När man har urfrästa spår som bildar kanaler på detta sätt kan man sticka in armeringsjärnen genom kanalerna i färdigt element och man behöver inte nödvändigtvis i förväg bestämma om elementen ska ha armering eller inte eller vilka element som behöver ha armering. Det kan slutanvändaren bestämma vid byggnationen. Sandwichpanelerna monteras vanligen på pelare med omkring 25 cm mellanrum mellan ändarna. Detta mellanrum isoleras och täcks efter monteringen.Figure 3 shows one of the rods 15 with the reinforcing bars 16,17 in milled grooves 18,19 in one surface which is to abut against the adjacent rod. When you have milled out grooves that form channels in this way, you can insert the rebar through the channels in the finished element and you do not necessarily have to decide in advance whether the elements should have reinforcement or not or which elements need reinforcement. The end user can decide this during construction. The sandwich panels are usually mounted on pillars with about 25 cm spacing between the ends. This space is insulated and covered after installation.

Kanalerna kan även användas för dold installation; en del av dem kan exempelvis förses med plaströr för senare montering av kablar.The ducts can also be used for concealed installation; some of them can, for example, be provided with plastic pipes for later mounting of cables.

Figur 4 visar änden på en sandwichpanel. Den har en ändplåt 22 med hål för armerings- järnen vars utstickande ändar är förankrade i ändplåten på något sätt, exempelvis med stukning eller med muttrar. Vid mineralullsisolering kan man även använda svetsning.Figure 4 shows the end of a sandwich panel. It has an end plate 22 with holes for the reinforcing bars, the protruding ends of which are anchored in the end plate in some way, for example by upsetting or with nuts. Welding can also be used for mineral wool insulation.

Armeringsjärnen är således hopfästa med varandra genom att vara fästa i ändplåten 22.The reinforcement bars are thus fastened to each other by being fastened to the end plate 22.

När isoleringen utgörs av mineralull skär man ut stavarna ur en skiva och vrider dem ett kvarts varv så att fiberriktningen kommer att ligga i längsgående plan vinkelrätt mot plåtarna, dvs med fibrer riktade tvärs plåtarna såsom indikeras i figurerna 2 och 3.When the insulation consists of mineral wool, cut the rods out of a board and turn them a quarter turn so that the fiber direction will be in the longitudinal plane perpendicular to the plates, ie with fibers directed across the plates as indicated in Figures 2 and 3.

Därigenom får mineralullsisoleringen förbättrad bärighet.As a result, the mineral wool insulation has improved bearing capacity.

Som visas i figur 2 har plåtarna 12,13 spont med en not 20 i ena änden och en fjäder 21 i andra änden. I noten finns en ej visad tätningslist. Ett sandwichelement staplas med plåtarnas not 20 nedåt på ett liggande undre element som har plåtarnas fiäder 21 uppåt så att skarven blir tät och inte kan ta in vatten.As shown in Figure 2, the plates 12,13 have tongue and groove with a groove 20 at one end and a spring 21 at the other end. There is a sealing strip (not shown) in the note. A sandwich element is stacked with the groove 20 of the plates downwards on a horizontal lower element which has the springs 21 of the plates upwards so that the joint becomes tight and cannot take in water.
