Abstract

The invention is a thin, reinforced construction slab consisting of at least two sub-slabs (11, 12) that are laminated around the reinforcement (13) by means of gluing.<IMAGE>

Description

15 20 25 30 35 8107643-2 Detta problem har nu lösts genom att, såsom anges i efterföl- jande patentkrav 1, varje delskiva är försedd med hanterings- armering, varvid samtliga delskivors hanteringsarmering tillsammans utgör åtminstone en del av byggskivans total- armering. This problem has now been solved in that, as stated in the appended claim 1, each sub-panel is provided with handling reinforcement, wherein the handling reinforcement of all sub-panels together form at least a part of the total reinforcement of the building board.

Hanteringsarmeringen kan bestå av remsor av glasfibertrâd eller av glasfiberband, som limmas till delskivan eller fås att vidhäfta denna vid gjutningen.The handling reinforcement can consist of strips of fiberglass wire or of fiberglass strips, which are glued to the partial board or made to adhere to it during casting.

Om hanteringsarmeringen anbringas i form av t.ex. parallella remsor med inbördes mellanrum, kan remsbredden och mellan- rummen anpassas så att vid sammanläggning av två delskivor dessas hanteringsarmeringar tillsammans kommer att utgöra den kompletta byggskivans totalarmering eller en del därav.If the handling reinforcement is applied in the form of e.g. parallel strips with mutual spaces, the strip width and the spaces can be adapted so that when joining two sub-panels, their handling reinforcements together will form the total reinforcement of the complete building board or part thereof.

Hanteringsarmeringen kan också bestå av i betongen inblandad glas-, plast- eller metallfiber.The handling reinforcement can also consist of glass, plastic or metal fiber mixed into the concrete.

Uppfinningen skall i det följande närmare belysas under hän- visning till bifogade ritning, på vilken fig. 1-6 i perspektiv visar olika utföringsformer av dels färdiga byggskivor dels delskivor enligt uppfinningen.The invention will be further elucidated in the following with reference to the accompanying drawing, in which Figures 1-6 show in perspective different embodiments of partly finished building boards and partly partial boards according to the invention.

Fig. 1 visar en byggskiva, bestående av två delskivor 11 och 12, av vilka den övre skivan 12 visas delvis uppbruten, och vilka medelst ett icke närmare visat limskikt är laminerade kring en av flera armeringstrådar 13 bestående armering.Fig. 1 shows a building board, consisting of two sub-boards 11 and 12, of which the upper board 12 is shown partially broken, and which by means of an adhesive layer (not shown in more detail) are laminated around a reinforcement consisting of several reinforcing wires 13.

Fig. 2 visar en delskiva 21 med spår 22 för längsgående tråd- armering. Två sådana spårförsedda skivor 21 kan sammanlimmas till en komplett byggskiva med armeringstrådar inlagda i spåren 22.Fig. 2 shows a sub-disc 21 with grooves 22 for longitudinal wire reinforcement. Two such grooved sheets 21 can be glued together into a complete building board with reinforcing wires inserted in the grooves 22.

Fig. 3 visar en delskiva 31 med utbredd armering i form av en folie 32, kring vilken skivan 31 och en ytterligare slät skiva är avsedda att genom limning lamineras. 10 15 20 25 30 8107643-2 Fig. 4 visar en delskiva 41 med hanteringsarmering - 1 detta fall i form av tre parallella armeringsremsor eller -band 42, 43, 44, som med mellanrum 45, 46 är limmade pâ skivan 41.Fig. 3 shows a partial disc 31 with extended reinforcement in the form of a foil 32, around which the disc 31 and a further smooth disc are intended to be laminated by gluing. Fig. 4 shows a sub-disc 41 with handling reinforcement - in this case in the form of three parallel reinforcement strips or strips 42, 43, 44, which are glued to the disc 41 at intervals 45, 46.

Denna hanteringsarmering behöver inte vara dimensionerad för att delskivan skall kunna klara större pâkänningar än den normala hanteringen vid tillverkning av en komplett byggskiva kräver.This handling reinforcement does not have to be dimensioned for the partial board to be able to withstand greater stresses than the normal handling when manufacturing a complete building board requires.

Såsom framgår är emellertid remsorna i fig. 4 osymmetriskt lagda, så att en remsa 42 sträcker sig utefter delskivans ena långkant, medan mellan den tredje remsan 44 och skivans andra lângkant finns ett mellanrum 47. Bredden av detta mel- lanrum 47 är, liksom av mellanrummen 45 och 46 mellan remsor- na 42 och 43 resp. 43 och 44, väsentligen lika med remsornas bredd. Genom detta osymmetriska arrangemang kan tvâ lika delskivor 41 limmas med hanteringsarmeringarna mot varandra, så att den ena delskivans mellanrum 47 hamnar mot den andra delskivans armeringsband 42, den ena delskivans armeringsband 44 mot den andra delskivans mellanrum 45 o.s.v.. Härigenom erhåller den färdiga byggskivan en armering, som består av delskivornas hanteringsarmeringar och kan utgöra byggskivans färdigarmering eller kan ytterligare kompletteras.As can be seen, however, the strips in Fig. 4 are laid asymmetrically, so that a strip 42 extends along one long edge of the sub-disc, while between the third strip 44 and the other long edge of the disc there is a gap 47. The width of this gap 47 is, as of the spaces 45 and 46 between the strips 42 and 43, respectively. 43 and 44, substantially equal to the width of the strips. By this asymmetrical arrangement, two equal sub-panels 41 can be glued with the handling reinforcements against each other, so that the space 47 of one sub-panel ends up against the reinforcement band 42 of the other sub-panel, the reinforcement strip 44 of one sub-panel against the space 45 of the other sub-panel, etc. , which consists of the sub-panels' handling reinforcements and can constitute the building board's finished reinforcement or can be further supplemented.

Fig. 5 visar en delskiva 51 med hanteringsarmering i form av i betongen inblandade fibrer 52.Fig. 5 shows a sub-disc 51 with handling reinforcement in the form of fibers 52 mixed into the concrete.

Fig. 6 slutligen, visar ett exempel på en av tre delskivor 81, 82 och 83 bestående byggskiva. Delskivorna 82 och 83 visas delvis uppbrutna, så att i detta fall längsgående tråd- armering 84 resp. 85 mellan skivorna 81 och 82 resp. 82 och 83 blivit synlig. Armeringarnas 84 och 85 tyngdpunkt faller i huvudsak i den kompletta byggskivans mitt. Liksom vid de övriga exemplen är delskivorna limmade till varandra och kring armeringen. 10 15 20 25 30 35 8107643-2 Såsom framgår är emellertid remsorna i fig. 4 osymmetriskt lagda, så att en remsa 42 sträcker sig utefter delskivans ena långkant, medan mellan den tredje ramsan 44 och skivans andra långkant finns ett mellanrum 47. Bredden av detta mel- lanrum 47 är, liksom av mellanrummen 45 och 46 mellan remsor- na 42 och 43 resp. 43 och 44, väsentligen lika med remsornas bredd. Genom detta osymmetriska arrangemang kan två lika delskivor 41 limmas med hanteringsarmeringarna mot varandra, så att den ena delskivans mellanrum 47 hamnar mot den andra delskivans armeringsband 42, den ena delskivans armeringsband 44 mot den andra delskivans mellanrum 45 o.s.v.. Härigenom erhåller den färdiga byggskivan en armering, som består av delskivornas hanteringsarmeringar och kan utgöra byggskivans färdigarmering eller kan ytterligare kompletteras.Fig. 6 finally, shows an example of a building board consisting of three sub-panels 81, 82 and 83. The sub-discs 82 and 83 are shown partially broken, so that in this case longitudinal wire reinforcement 84 resp. 85 between the discs 81 and 82 resp. 82 and 83 become visible. The centers of gravity of the reinforcements 84 and 85 fall mainly in the middle of the complete building board. As with the other examples, the sub-panels are glued to each other and around the reinforcement. As can be seen, however, the strips in Fig. 4 are laid asymmetrically, so that a strip 42 extends along one long edge of the sub-disc, while between the third strip 44 and the other long edge of the disc there is a gap 47. The width of this gap 47 is, as well as of the gaps 45 and 46 between the strips 42 and 43 resp. 43 and 44, substantially equal to the width of the strips. By this asymmetrical arrangement, two equal sub-panels 41 can be glued with the handling reinforcements against each other, so that the space 47 of one sub-panel ends up against the reinforcement band 42 of the other sub-panel, the reinforcement strip 44 of one sub-panel against the space 45 of the other sub-panel, etc. , which consists of the sub-panels' handling reinforcements and can constitute the building board's finished reinforcement or can be further supplemented.

Pig. S visar en delskiva 51 med hanteringsarmering i form av i betongen inblandade fibrer 52.Pig. S shows a sub-disc 51 with handling reinforcement in the form of fibers 52 mixed into the concrete.

Fig. 6 visar ett exempel på hur två byggskivor 61 och 62 en- ligt uppfinningen kan fogas till varandra. Båda skivorna är i gränsområdet mellan resp. delskivor försedda med längs ski- vornas långkanter löpande spår 63. Formen på tvâ sådana mitt för varandra befintliga spår motsvarar formen på en lös fjä- der 64, som vid fogning av flera skivor tjänar som styrning mellanpskivorna.Fig. 6 shows an example of how two building boards 61 and 62 according to the invention can be joined to each other. Both discs are in the boundary area between resp. sub-discs provided with grooves 63 running along the long edges of the discs. The shape of two such opposite grooves corresponds to the shape of a loose spring 64, which when joining several discs serves as a guide for the intermediate discs.

Fig. 7 visar ett annat exempel på hur två byggskivor 71 och 72 enligt uppfinningen kan sammanfogas. De båda skivornas delskivor är härvid limmade till varandra med någon förskjut- ning, så att trappstegsliknande långkanter erhålles, vilka då skivorna förs mot varandra ger en överlappande fog.Fig. 7 shows another example of how two building boards 71 and 72 according to the invention can be joined together. The sub-panels of the two panels are glued to each other with some displacement, so that step-like longitudinal edges are obtained, which when the panels are moved towards each other give an overlapping joint.

Fig. 8, slutligen, visar ett exempel på en av tre delskivor 81, 82 och 83 bestående byggskiva. Delskivorna 82 och 83 vi- sas delvis uppbrutna, så att i detta fall längsgående trådar- mering 84 resp. 85 mellan skivorna 81 och 82 resp. 82 och 83 blivit synlig. Armeringarnas 84 och 85 tyngdpunkt faller i 8107643-2 huvudsak i den kompletta byggskivans mitt. Liksom vid de övriga exemplen är delskivorna limmade till varandra och kring armeringen.Fig. 8, finally, shows an example of a building board consisting of three sub-panels 81, 82 and 83. The sub-discs 82 and 83 are shown partially broken, so that in this case longitudinal wire reinforcement 84 resp. 85 between the discs 81 and 82 resp. 82 and 83 become visible. The centers of gravity of the reinforcements 84 and 85 fall in 8107643-2 mainly in the middle of the complete building board. As with the other examples, the sub-panels are glued to each other and around the reinforcement.
