Description

Selvbærende takelement og takkonstruksjon med dette'element. Self-supporting roof element and roof construction with this element.

Den foreliggende oppfinnelse vedrører et selvbærende takelement med stor spennvidde, fremstilt av profilert plate og isoleringsmateriale.. Oppfinnelsen vedrører også en takkonstruksjon i hvilken dette element utnyttes, hvorved takkonstruksjonen får samme gode varmeisolerende egenskap som takelementet. The present invention relates to a self-supporting roof element with a large span, made of profiled plate and insulating material. The invention also relates to a roof construction in which this element is used, whereby the roof construction has the same good heat-insulating properties as the roof element.

Oppfinnelsen som nærmere definert i de etterfølgende krav, skal i det følgende beskrives med henvisning til teg-ningen, hvor The invention, as further defined in the subsequent claims, shall be described below with reference to the drawing, where

fig. 1 viser et takelement i tverrsnitt og inne-bygget i en takkonstruksjon, mens fig. 1 shows a roof element in cross-section and built into a roof structure, while

fig.. 2 viser samme element i lengdesnitt og like-ledes innbygget i en takkonstruksjon. Fig. 2 shows the same element in longitudinal section and likewise built into a roof structure.

Et takelement ifølge oppfinnelsen inneholder langsgående, bærende Z-profiler 1 hvilke danner elementets kanter. Z-profilen er i steget forsynt med et innad, mot elementet vendt trinn 2. Z-profilens nedre flens 3 er rettet innad mot elementet og dets kant 4 er bøyd utad og tilbake mot profilens steg. Z-profilens øvre flens er vendt utad fra elementet og dets kant- 6 er bøyd nedad. Elementets underside utgjøres av en profilert plate 7 med profileringen på tvers av elementet og festet ovenpå den ombøyde kant på den undre flens 3. Tverrgående hattprofiler 8' er festet på trinnet 2 i Z-profilens steg. Hattprofilene 8 understøtter A roof element according to the invention contains longitudinal, load-bearing Z-profiles 1 which form the edges of the element. In the step, the Z-profile is provided with a step 2 facing inwards towards the element. The Z-profile's lower flange 3 is directed inwards towards the element and its edge 4 is bent outwards and back towards the step of the profile. The upper flange of the Z-profile faces outwards from the element and its edge 6 is bent downwards. The underside of the element is made up of a profiled plate 7 with the profiling across the element and attached on top of the bent edge of the lower flange 3. Transverse hat profiles 8' are attached to step 2 in the step of the Z-profile. The hat profiles 8 support

elementets overflate bestående av langsgående profilert plate 9. Antall hattprofiler velges slik at tilstrekkelig bæreevne oppnås i overflaten. Den profilerte plate på overflaten er hensiktsmessig smalere enn elementet slik at elementets kanter forblir åpne. the element's surface consisting of longitudinally profiled plate 9. The number of hat profiles is chosen so that sufficient load-bearing capacity is achieved in the surface. The profiled plate on the surface is suitably narrower than the element so that the edges of the element remain open.

Elementets endeflater dekkes hensiktsmessig opp til trinnet i Z-profilens steg med plater 10,11 som ved hjelp av flensede kanter festes i Z-profilene. The element's end surfaces are appropriately covered up to the step in the Z-profile step with plates 10,11 which are attached to the Z-profiles by means of flanged edges.

Den profilerte plate 7,9 i overflaten utgjøres hensiktsmessig av trapesprofilert plate, hvilken likesom øvrige platedetaljer hensiktsmessig er forsinket og når det gjelder ytterflater endog plastbelagte. Sammenfestingen skjer hensiktsmessig ved nitting, men også liming eller sveising kan anvendes. The profiled plate 7,9 in the surface is suitably made up of a trapezoidal profiled plate, which, like other plate details, is suitably delayed and, in the case of outer surfaces, even plastic-coated. The joining is conveniently done by riveting, but gluing or welding can also be used.

Isoleringen utføres hensiktsmessig av mineralull idet en tykk mineralullplate 12 eller sprøytet løs ull legges i elementet opp til jevn høyde med trinnet i Z-profilens steg, hvoretter mineralullmatter 13 kledd med vindtett papir legges, mellom hatteprofilene ovenfor trinnet. Derved sørges det for at det etterlates et luftrom 15 under overflaten for at eventuell fuktighet skal kunne ventileres bort. Langs elementets kanter på en bredde som omtrent tilsvarer elementets tykkelse, legges mineralull 1^4 helt opp til elementets overflate. Under mineralullisoleringen plasseres en plastfolie 16 som trekkes opp langs Z-profilene og tapes fast i stegene. Herved kan det oppnås en fullstendig diffusjonstett konstruksjon ved sammensetting av elementene. The insulation is suitably made of mineral wool, as a thick mineral wool plate 12 or sprayed loose wool is placed in the element up to an even height with the step in the Z-profile step, after which mineral wool mats 13 covered with windproof paper are placed between the hat profiles above the step. This ensures that an air space 15 is left below the surface so that any moisture can be vented away. Mineral wool 1^4 is laid all the way up to the element's surface along the element's edges at a width that roughly corresponds to the element's thickness. A plastic foil 16 is placed under the mineral wool insulation, which is pulled up along the Z-profiles and taped to the steps. In this way, a completely diffusion-tight construction can be achieved when the elements are put together.

Takelementene ifølge oppfinnelsen kan gjøres med meget større lengde, f.eks. 10 meter og større. Derved kan de anvendes for tak med stor spennvidde og nå fra mønebjelke 17 til yttervegg 18. Sprekken ved mønebjelken fylles med isolering 19 og dekkes med en møneplate 20, hensiktsmessig en hattprofil, som tettes mot de profilerte overflater på elementene. The roof elements according to the invention can be made with much greater length, e.g. 10 meters and larger. Thereby, they can be used for roofs with a large span and reach from ridge beam 17 to outer wall 18. The crack at the ridge beam is filled with insulation 19 and covered with a ridge plate 20, suitably a hat profile, which is sealed against the profiled surfaces of the elements.

Takelementene plasseres ved siden av hverandre slik at Z-profilenes overflenser 5 dekker og fikserer hverandre. I skjøten innlegges hensiktsmessig et tettingsbånd. Over skjøten plasseres en mineralullisolering 21 som dekkes med en hattprofil av plate 22. Langs husets gavl 23 dekkes elementkanten av en med isolering fylt plateprofil 2^, som tjener som vindskive. Langs takets nedre kant legges elementene hensiktsmessig mot en isolert takrenne av plate 25. The roof elements are placed next to each other so that the Z profiles' top flanges 5 cover and fix each other. A sealing tape is suitably inserted into the joint. Above the joint, a mineral wool insulation 21 is placed which is covered with a hat profile of plate 22. Along the house's gable 23, the element edge is covered by a plate profile 2^ filled with insulation, which serves as a wind disc. Along the lower edge of the roof, the elements are appropriately placed against an insulated roof gutter made of plate 25.
