Opfindelsen angår et bølgeformet bånd til anvendelse i bygningskonstruktioner såsom tage og vægge med planbeklædning, f.eks. krydsfiner, spånplader, brædder, plane tagplader, hvor båndet placeres på oversiden af en underliggende konstruktion eksempelvis et træskelet eller spær mellem denne og planbeklædningen, så der fra den ene til den anden side af båndene dannes tværstillede kanaler i anlæg med den underliggende konstruktion samt tilsvarende tværstillede kanaler under planbeklædningen, ligesom opfindelsen angår en bygningskonstruktion med sådant bånd.The invention relates to a wavy band for use in building structures such as roofs and walls with flat cladding, e.g. plywood, particleboard, boards, flat roofing sheets where the strip is placed on the upper surface of an underlying structure, for example a wooden skeleton or rafter between it and the floor covering, so that from one to the other side of the strips, transverse channels are formed in systems with the underlying structure and the like. The invention relates to a building structure with such a strip.

I ansøgerens DK-patentskrift nr. 122 831 er der beskrevet en tagkonstruktion, hvori der anvendes bølgeformede bånd, hvor bølgerne står vinkelret på båndenes længderetning. Udover i tagkonstruktioner anvendes båndene tillige i vid udstrækning ved brædde- og pladebeklædning af vægge, f.eks. facadevægge og indvendig beklædning af kældervægge, hvor en ventilering af konstruktionen er absolut påkrævet. Ansøgeren har udøvet opfindelsen og fremstillet et sortiment af bånd af galvaniseret stålplade med forskellig godstykkelse og med forskellige bølgehøjder og båndbredde.Applicant DK Patent No. 122,831 discloses a roof structure employing corrugated strips, the waves being perpendicular to the longitudinal direction of the strips. In addition to roof structures, the strips are also widely used in wall and slab cladding of walls, e.g. facade walls and interior lining of basement walls, where a ventilation of the structure is absolutely required. The applicant has practiced the invention and manufactured an assortment of galvanized steel sheet strips of varying thickness and of different wave heights and bandwidths.

Med den stigende erkendelse af nødvendigheden af udluftning af selve bygningskonstruktionerne, navnlig på den kolde side af isoleringslag, er bevidstheden skærpet omkring at etablere og holde et hulrum intakt mellem isoleringslagets overside og f.eks. tagdækningslagets underside. Det skal bl.a. ses i sammenhæng med, at bygninger i dag generelt gøres tættere end førhen og samtidig anvendes tykkere isoleringslag. Hvor man tidligere så at isoleringslaget i tagkonstruktioner var tyndere eller kun lige så tykt som spærtræets højde, ser man nu at isoleringslaget er tykkere end spærtræets nødvendige bærehøjde. Alt dette tenderer til, at man anvender bølgeformede bånd med større bølgehøjde for at.få en bedre udluftning. Dette afstedkommer så et andet problem,With the increasing recognition of the necessity of venting the building structures themselves, especially on the cold side of insulation layers, awareness has been sharpened around establishing and keeping a void intact between the top of the insulation layer and e.g. the underside of the roofing layer. It should include can be seen in the context that buildings are generally made closer than before and thicker insulation layers are used at the same time. Where it was previously seen that the insulation layer in roof structures was thinner or only as thick as the height of the rafter, it is now seen that the insulation layer is thicker than the required height of the rafter. All of this tends to use wavy bands with greater wave height to get better venting. This then causes another problem,

2 nemlig at bølgerne bliver så høje, at mus, rotter, småfugle og lignende uønskede dyr får friere adgang til konstruktionen. Bortset fra de umiddelbare gener, kan de ødelægge konstruktionen og særlig farligt bliver det, hvis dyrene begynder at gnave i den elektriske installation.2 that the waves become so high that mice, rats, small birds and similar undesirable animals are given more free access to the structure. Apart from the immediate nuisance, they can destroy the construction and become especially dangerous if the animals start gnawing in the electrical installation.

Formålet med opfindelsen er at angive en sådan udformning af båndene, at ventilationstværsnittet kan øges uden at give smådyr og -fugle friere adgang til konstruktionen. Den opgave løses ifølge opfindelsen ved, at udforme de bølgeformede bånd, så bølgerne danner en skrå vinkel, fortrinsvis på ca. 45° i forhold til båndets længderetning. Da bølgerne har et skråt forløb i forhold til båndets længderetning, kan båndene lægges oven på hinanden, når disse vendes, så bølgerne går skråt henholdsvis i den ene og den anden retning, hvorved bølgerne kommer til at ride oven på hinanden. Ventilationstværsnittet bliver da dobbelt i forhold til et enkelt bånd, men uden at åbningerne øges tilsvarende. Det skrå forløb af bølgerne har desuden den fordel, at trædefladen alt andet lige bliver større. I tagkonstruktioner ved skotrender og lignende steder kan båndene vendes, så vand og fygesne ikke så let fanges, men tværtimod afvises.The object of the invention is to provide such a design of the belts that the ventilation cross section can be increased without giving small animals and birds more access to the construction. The task according to the invention is solved by forming the wavy bands so that the waves form an oblique angle, preferably of approx. 45 ° relative to the longitudinal direction of the belt. As the waves have an oblique gradient with respect to the longitudinal direction of the belt, the bands can be laid on top of each other as they are turned, so that the waves are inclined in one and the other direction, whereby the waves will ride on each other. The ventilation cross-section then becomes double in relation to a single band, but without increasing the openings accordingly. In addition, the sloping course of the waves has the advantage that the tread surface everything else just becomes larger. In roof structures at footpaths and similar places, the straps can be turned so that water and the pigeons are not so easily caught, but on the contrary rejected.

På tegningens fig. l er i perspektiv vist et stykke af et bånd udformet ifølge opfindelsen med bølger, der danner en vinkel på ca. 45° med båndets længderetning.In the drawing FIG. 1 is a perspective view of a piece of a band formed according to the invention with waves forming an angle of approx. 45 ° with the longitudinal direction of the belt.

Fig. 2 viser to sådanne bånd anbragt ovenpå hinanden, hvor bølgerne rider bølgetop mod bølgetop.FIG. 2 shows two such bands arranged one on top of the other, with the waves riding wave peak towards wave peak.

Båndene finder især anvendelse ved flade tage eller tage med undertag af krydsfinér eller lignende samt ved trævægbeklædning.The strips are especially applicable for flat roofs or roofs with the exception of plywood or the like and for wooden wall coverings.
