Description

Fremgangsmåte ved fremstilling av konstruksjonselementer. Procedure for manufacturing structural elements.

Foreliggende oppfinnelse angår en The present invention relates to a

fremgangsmåte ved fremstilling av konstruksjonselementer, som består av to eller procedure for the production of construction elements, which consist of two or

flere med mellomrom anordnede plater, multiple spaced plates,

mellom hvilke er anbragt et innlegg bestående av i bølgeform pressede strimler av between which is placed an insert consisting of strips pressed in wave form

hensiktsmessig materiale, f. eks. kryssfinér. appropriate material, e.g. plywood.

Strimlenes bølgetopper blir hensiktsmessig limt fast til platene, og dette må The wave crests of the strips are appropriately glued to the plates, and this must

skje under utøvelse av et visst trykk. Da strimlene imidlertid har en viss bøyelighet, happen under the application of a certain pressure. However, since the strips have a certain flexibility,

som kanskje ikke er like stor for alle strimler, vil det kunne inntreffe at det plateformede konstruksjonselement under pres-ningen ikke får jevn tykkelse eller at det ikke blir plant. Foreliggende oppfinnelse which may not be the same for all strips, it could happen that the plate-shaped structural element does not have a uniform thickness during pressing or that it does not become flat. Present invention

har til hensikt å sikre, at konstruksjons-elementet overalt får samme tykkelse og dessuten blir helt plant, og karakteriseres is intended to ensure that the construction element has the same thickness everywhere and is also completely flat, and is characterized

ved at det mellom platene anbringes løse in that loose ones are placed between the plates

list- eller klossformede avstandsstykker, som anordnes i mellomrommene mellom de bølgeformede strimler, hvilke avstandsstykker fjernes efter at konstruksjons-elementet er ferdigpresset og sammenlimt. strip- or block-shaped spacers, which are arranged in the spaces between the corrugated strips, which spacers are removed after the structural element has been pressed and glued together.

Oppfinnelsen er anskueliggjort på hosstående tegning, hvor Fig. 1 i perspektiv viser en del av et konstruksjonselement med listformede avstandsstykker, mens Fig. 2, likeledes i perspektiv, viser en annen utførelsesform av et konstruksjonselement med avstandsstykker i form av klosser. The invention is illustrated in the accompanying drawing, where Fig. 1 in perspective shows part of a construction element with strip-shaped spacers, while Fig. 2, likewise in perspective, shows another embodiment of a construction element with spacers in the form of bricks.

I fig. 1 betegner 1, 2 og 3 tre plater, In fig. 1 denotes 1, 2 and 3 three plates,

mellom hvilke er anbragt parallelle, av kryssfinér eller annet materiale bestående between which are placed parallel, made of plywood or other material consisting

bølgeformede strimler 4, som har en viss av-stand fra hverandre og hvis bølgetopper 8 er fastlimt til platene. Da limingen må wave-shaped strips 4, which have a certain distance from each other and whose wave crests 8 are glued to the plates. Then the gluing must

foregå under utøvelse av et visst trykk på ytterplatene 1 og 3 kan man risikere at det take place while exerting a certain amount of pressure on the outer plates 1 and 3, there is a risk that

plateformede konstruksjonselement på grunn av strimlenes bøyelighet ikke blir jevntykt overalt og at det ikke blir helt plant. For å hindre dette anbringes det mellom platene løse avstandsstykker i form av lister 5, som i det viste tilfelle forløper parallelt med strimlene 4 i mellomrommene mellom disse. Listenes tykkelse vinkelrett på platene er valgt således, at det under sammenpresningen kun utøves et så stort trykk på strimlenes bølgetopper som det kreves for limingen, så at bølgestrimlene plate-shaped construction element, due to the flexibility of the strips, the thickness is not uniform everywhere and that it is not completely flat. To prevent this, loose spacers in the form of strips 5 are placed between the plates, which in the case shown run parallel to the strips 4 in the spaces between them. The thickness of the strips perpendicular to the plates is chosen so that during the compression only as much pressure is exerted on the wave crests of the strips as is required for the gluing, so that the wave strips

ikke blir bøyet i nevneverdig grad. Kon-struksjonselementets tykkelse vil således is not bent to any significant extent. The thickness of the structural element will thus

bestemmes av avstandslistenes tykkelse, og elementet blir helt plant da strimlene ikke kan bøyes i forskjellig grad under pres-ningen og limingen. Avstandslistene kan også være anordnet på andre måter enn vist i fig. 1. is determined by the thickness of the spacer strips, and the element becomes completely flat as the strips cannot be bent to different degrees during the pressing and gluing. The distance strips can also be arranged in other ways than shown in fig. 1.

Ved konstruksjonselementer, hvor bølgestrimlene krysser hverandre som vist In the case of structural elements, where the wave strips cross each other as shown

ved 4 og 6 i fig. 2, kan det være vanskelig å få anbragt langstrakte avstandslister. at 4 and 6 in fig. 2, it may be difficult to place elongated distance strips.

Man kan da anvende avstandsstykker i Spacers can then be used i

form av løse klosser 7, som anbringes på passende steder mellom platene. form of loose bricks 7, which are placed in suitable places between the plates.

Da såvel listene 5 som klossene 7 er Then both the lists 5 and the blocks 7 are

løse, kan de fjernes når elementet er ferdig. solve, they can be removed when the item is finished.
