Fremstilling af vægelement i sandwichkonstruktion samt sAdantManufacture of wall element in sandwich construction as well as sAdant
VÆGELEMENTwall
Den foreliggende opfindelse angår en særlig fremgangsmåde til fremstilling af et 5 termisk isoleret vægelement i sandwichkonstruktion, et anlæg til fremstilling af et J sådant vægelement samt selve vægelementet.The present invention relates to a particular method for producing a thermally insulated wall element in sandwich construction, a plant for producing such a wall element, and the wall element itself.
Baggrund 10 Det er i dag kendt at samle færdige vægelementer på værksted til senere montering på byggestedet, hvor disse vægelementer er fremstillet i en sandwichkonstruktion bestående af to yderplader og et afstandsgivende skelet mellem disse, fx af trærigler, samt en dampspærre, fx en kraftig plasticdug, placeret på den side af vægelementet, der vil vende mod den side af byggeriet, hvor damptrykket er højst, dvs. hvor 15 elementet anvendes som en ydervæg vil dampspærren være placeret på den inderste yderplades inderside for at forhindre kondensation af vandddamp i skelettet. Yderplademe er normalt fastgjort til skelettet ved hjælp af skruer, der føres gennem yderplademe og ind i skelettet. Der kan yderligere være tilvejebragt isoleringsmateriale, fx mineraluld, mellem yderplademe for termisk og eventuel 20 akustisk isolering.Background 10 It is known today to assemble finished wall elements in the workshop for later installation at the construction site, where these wall elements are manufactured in a sandwich structure consisting of two outer plates and a spacer skeleton between them, for example of wooden bars, as well as a vapor barrier, for example a strong plastic tablecloth. , located on the side of the wall element which will face the side of the building where the vapor pressure is highest, ie. where the element is used as an outer wall, the vapor barrier will be located on the inside of the inner outer plate to prevent condensation of water vapor in the skeleton. The outer plates are usually attached to the skeleton by means of screws which pass through the outer plates and into the skeleton. Insulation material, for example mineral wool, may be further provided between the outer panels for thermal and possibly acoustic insulation.
Kort beskrivelse af opfindelsenBrief Description of the Invention
Med den nærværende opfindelse tilvejebringes isolerede vægelementer, der er limet 25 sammen, hvorved det er muligt at opnå en lufttæt konstruktion, således at en dampspærre er unødvendig, i modsætning til det kendte vægelement, der er skruet sammen, hvorved der dannes åbninger hvor damp kan trænge igennem. Isoleringsmateriale indsprøjtes i vægelementets hulrum, som efterfølgende forsegles. Yderligere er det limede element mere rengøringsvenligt, idet der ikke forefindes de 30 fordybninger, der eller dannes ved skruerne, med mindre disse udsparties. Limning anses normalt ikke for at være anvendelig til at samle isolerede vægelementer med 2 DK 176189 B1 rigelskelet, idet den tid, det tager at udlægge mineraluldsmåtter mellem rigleme nødvendiggør, at der anvendes en lim med en lang åbningstid, dvs. hvor der kan gå lang tid mellem limpåføring og sammenpresning af de elementer, der skal limes sammen, hvilket igen medfører en lang pressetid i størrelsesordnen 6-8 timer. Med 5 fremgangsmåden ifølge den nærværende opfindelse kan anvendes en limtype med kort åbningstid, fx 20 minutter, og dertil hørende kort pressetid fx 20 minutter, t hvilket medfører en hurtig og rationel arbejdsgang og en meget fordelagtig udnyttelse af produktionsudstyret.The present invention provides insulated wall elements glued together, thereby providing an airtight construction so that a vapor barrier is unnecessary, as opposed to the known wall element screwed together, thereby creating openings where steam can be formed. penetrate. Insulating material is injected into the cavity of the wall element, which is subsequently sealed. Further, the glued member is more clean-friendly as there are no 30 recesses formed or formed by the screws unless these are cut out. Bonding is usually not considered to be useful for assembling insulated wall elements with the 2-frame 171 skeleton, since the time it takes to lay mineral wool mats between the ridges necessitates the use of a glue with a long opening time, ie. where there can be a long time between glue application and compression of the elements to be glued, which in turn causes a long pressing time in the order of 6-8 hours. With the method of the present invention, a glue type having a short opening time, e.g., 20 minutes, and associated short pressing time, e.g., 20 minutes, can be used, which results in a fast and rational operation and a very advantageous use of the production equipment.

Det er principielt underordnet om dysen indføres igennem topremmen eller bundremmen.In particular, the present invention relates to a method of manufacturing a wall element comprising the steps of providing a wall element comprising a first outer plate and a second outer plate which are substantially the same extent and positioned together, and a plurality of elongated ridges bonded between inner faces of these two outer plates, said bars having two parallel, opposite faces extending longitudinally of said bars, said bars being arranged along a first outer edge and an opposing second outer edge of said first outer plate, so that substantially unbroken top and bottom straps are formed along the first outer edge and the second outer edge, respectively, and a plurality of the straps are further arranged to extend 20 parallel to each other and substantially perpendicular to the top and bottom straps so that they form essentially uninterrupted parallel line runs between the top and bottom straps, and so it is directed that each of the parallel bolt courses abut substantially close to both the top and bottom straps, forming at least one in the substantially 25 airtight chamber between the two outer plates, the top and bottom straps and the unbroken parallel bolt strips, and insulate the wall member by in each such chamber, through an aperture formed in the top belt (respectively in the bottom belt), introducing a nozzle arranged on an elongated feeding device, the nozzle being guided near the bottom belt (and the top belt respectively) and an insulating material being injected into the chamber during gradual withdrawal of the nozzle; so that the chamber is substantially completely filled with the insulating material, after which the nozzle is withdrawn from the chamber and the opening in DK 176189 B1 3 top strap (respectively in the bottom strap) is sealed. It is in principle minor whether the nozzle is inserted through the top belt or bottom belt.
Yderplademe kan fx være af krydsfiner, fx vandfast krydsfiner, men det foretrækkes 5 at anvende plader af træspåner med et indhold af 15-40 vægtprocent, fortrinsvis 25-j 35 vægtprocent cement, såsom 30 vægtprocent, og med en tykkelse på 8 til 20 millimeter, fortrinsvis på 10 til 16 millimeter, såsom 12 millimeter. Hver af yderplademe, dvs. den første yderplade og den anden yderplade, kan hver især bestå af et antal delplader, typisk af standardstørrelsen 120 gange 240 centimeter eller 10 plader udskåret heraf, til dannelse af store vægelementer. Kanterne hvor delplademe stødes sammen kan eventuelt fuges med en fugttætnende fugemasse.The outer panels may, for example, be made of plywood, e.g. waterproof plywood, but it is preferred to use wood chip boards having a content of 15-40% by weight, preferably 25-35% by weight of cement, such as 30% by weight, and having a thickness of 8 to 20 millimeters. , preferably of 10 to 16 millimeters, such as 12 millimeters. Each of the outer plates, ie. the first outer plate and the second outer plate, each may consist of a plurality of subplates, typically of the standard size 120 by 240 centimeters or 10 plates cut therefrom, to form large wall elements. The edges where the subplates are pushed together can optionally be sealed with a moisture-sealing sealant.
Rigleme er fortrinsvis fremstillet af træ, hvor det foretrækkes at anvende træ af styrkeklasse Kl 8, fx i form af lange rigler, der er fingersamlet i længderetningen, 15 men andre rigler, fx galvaniserede stålrigler kan anvendes. Vægelementemes samlede tykkelse er typisk mellem 50 og 350 millimeter.The bars are preferably made of wood, where it is preferred to use timber of strength class 8, for example in the form of long bars which are longitudinally joined together, but other bars, eg galvanized steel bars can be used. The total thickness of the wall elements is typically between 50 and 350 millimeters.
Isoleringsmaterialet er fortrinsvis et granulært materiale, fortrinsvis træuld, der er brandimprægneret, fx. med ammoniumpolyfosfat, men der kan fx også anvendes 20 granuleret mineraluld, brandimprægneret papiruld eller et opskummende materiale. Imprægneret træuld har desuden fordelagtige egenskaber med hensyn til brandhæmning og til fugtighedsregulering, idet træulden kan optage og afgive fugt, der trænger igennem væggen, og hindrer dermed kondensering i træskelettet, hvilket kan føre til råd.The insulating material is preferably a granular material, preferably wood wool, which is fire impregnated, e.g. with ammonium polyphosphate, but for example 20 granular mineral wool, fire impregnated paper wool or a foaming material can also be used. In addition, impregnated wood wool has advantageous properties with regard to fire retardation and moisture control, as the wood wool can absorb and release moisture penetrating the wall, thus preventing condensation in the wood skeleton, which can lead to advice.

When all the rows are placed according to a predetermined arrangement, the second outer plate is applied by the robot 5, and an element conveyor 9 leads the wall element 3 to the press 10, where the two outer plates are pressed against each other with a predetermined force for a predetermined time, e.g., 20 minutes, so that the bonding between the 20 outer plates and the strips achieves the required strength. The element conveyor 9 guides
vægelementet 3 videre til isoleringspladsen 11, hvor der dels dannes åbninger i Ithe wall element 3 further to the insulation site 11, where apertures are formed in I
topremmen 12 og tværremme 13, dels indføres dysen (ikke vist) på en teleskopstang j til isolering af samtlige hulrum i vægelementet, og endeligt afproppes de dannede åbninger i topremmen 12. Endeligt føres vægelementet 3 ud over enden af 25 elementtransportøren 9 og vendes til lodret stilling og transporteres bort til lager.top strap 12 and transverse straps 13, and partly the nozzle (not shown) is inserted on a telescopic rod j to insulate all of the cavities in the wall element, and finally the formed openings in the top strap 12. Finally, the wall element 3 is passed beyond the end of the element conveyor 9 and is turned vertically. position and transported away to warehouse.
Med fremstillingsmetoden ifølge den nærværende opfindelse er det blevet muligt at fremstille de isolerede, limede vægelementer på én produktionslinje, idet presning tager forholdsvis kort tid, og de enkelte trin dermed tager omtrent samme tid, hvilket 30 er en forudsætning for at anvende én produktionslinje og for den deraf følgende automatisering af processen.With the manufacturing method of the present invention, it has become possible to produce the insulated, glued wall elements on one production line, with pressing taking relatively short time, and the individual steps thus taking approximately the same time, which is a prerequisite for using one production line and for the resulting automation of the process.
