Description

Fremgangsmåte for fremstilling av skalltak. Procedure for the production of shell roofs.

Denne oppfinnelse angår en fremgangsmåte for fremstilling, av skalltak, spesielt frittbærende skalltak, som er tauet i forskjellige retninger. This invention relates to a method for producing shell roofs, especially free-standing shell roofs, which are roped in different directions.

Skalltak av denne art, som i det ve-sentlige har form av en hyperbolisk para-boloid (og derfor kalles «Hyppar»-skalltak) egner seg spesielt godt for fremstilling i tre, og særlig når det gjelder prisen på det dertil nødvendige tremateriale har slike tak en fordel likeoverfor andre tak-konstruksjoner. Shell roofs of this type, which essentially have the shape of a hyperbolic paraboloid (and are therefore called "Hyppar" shell roofs) are particularly suitable for production in wood, and especially when it comes to the price of the necessary wood material such roofs an advantage over other roof constructions.

Saken er imidlertid den at takene The thing is, however, that the roofs

må fremstilles på byggestedet. De trelag som trenges for oppbyggingen av taket, bør for å oppnå en god forbindelse som er i stand til å oppta de opptredende krefter, limes på hverandre, hvilket er prak-tisk talt umulig under mindre gode kli-matiske forhold. Av denne grunn er slik skalltak ytterst kostbare når de en sjel-den gang kommer til anvendelse. must be produced on the construction site. The layers of wood needed for the construction of the roof should be glued to each other in order to achieve a good connection that is able to absorb the acting forces, which is practically impossible in less favorable climatic conditions. For this reason, such shell roofs are extremely expensive when they are rarely used.

Hensikten med oppfinnelsen er å an-vise en fremgangsmåte for fremstilling av skalltak i transportable deler, som, kan settes sammen på byggestedet uten bruk av et ekstrabygg. The purpose of the invention is to provide a method for producing shell roofs in transportable parts, which can be assembled on the building site without the use of an additional building.

Takets byggekostnader blir herved ve-sentlig redusert, og dessuten behøver de for fremstillingen av takene nødvendige fagfolk ikke sendes til byggestedet, og da delene ikke skal limes på hverandre på byggeplassen, kan man utelate den ellers nødvendige, provisoriske overdekning under byggingen. Fremgangsmåten ifølge oppfinnelsen karakteriseres ved at det på en bygningssjablon oppbygges en takplate ved sammenføyning av to eller flere på hverandre anbragte lag, hvilken plate deles i av to eller flere lag bestående plate-deler, og ved at en annen takplate, be-stemt til å anbringes over den førstnevn-te plate, likeledes fremstilles ved sam-menføyning av to eller flere lag, hvilken annen plate også oppdeles i deler, hvorpå de av deler bestående takplater på byggeplassen anbringes på hverandre og forbindes forskyvningsfast med hverandre. The construction costs of the roof are thereby significantly reduced, and furthermore, the professionals required for the production of the roofs do not need to be sent to the construction site, and as the parts are not to be glued together on the construction site, the otherwise necessary temporary covering during construction can be omitted. The method according to the invention is characterized by the fact that a roof plate is built up on a building template by joining two or more layers placed on top of each other, which plate is divided into plate parts consisting of two or more layers, and by another roof plate, determined to is placed over the first-mentioned plate, likewise produced by joining two or more layers, which second plate is also divided into parts, whereupon the roof plates consisting of parts on the building site are placed on top of each other and connected to each other in a displacement-proof manner.

Den ene takplate kan f. eks. oppta samtlige i taket opptredende trykkrefter, mens den annen takplate tjener til å oppta alle opptredende strekkrefter. One roof plate can e.g. absorb all compressive forces occurring in the roof, while the other roof plate serves to absorb all tensile forces occurring.

Da det herved mellom de to takplater innbyrdes bare opptrer forskyvnings-krefter, behøver de to plater ikke å limes på hverandre, og en sammennagling av platene er tilstrekkelig. Since only displacement forces occur between the two roof plates, the two plates do not need to be glued to each other, and nailing the plates together is sufficient.

Ifølge oppfinnelsen er det hensikts-messig at hver av platene oppdeles etter delelinjer som løper parallelt i forhold til hverandre. According to the invention, it is appropriate that each of the plates is divided according to dividing lines that run parallel to each other.

Et utførelseseksempel av oppfinnelsen An embodiment of the invention

er anskueliggjort på tegningene. is shown in the drawings.

Fig. 1 viser en bygning i perspektiv og utstyrt med et i forskjellige retninger buet skalltak, som er frittbærende. Fig. 2 viser et diagram av det i fig. 1 Fig. 1 shows a building in perspective and equipped with a shell roof curved in different directions, which is free-supporting. Fig. 2 shows a diagram of that in fig. 1

viste skalltak. showed shell roofs.

Fig. 3 viser i perspektiv det i fig. 1 viste skalltak, hvor konstruksjonen av taket fremgår ved at visse deler er bortskå-ret, og fig. 4 viser hvor enkelt et ifølge oppfinnelsen fremstillet skalltak kan transporteres. Fig. 3 shows in perspective what in fig. 1 showed a shell roof, where the construction of the roof can be seen by the fact that certain parts have been cut away, and fig. 4 shows how easily a shell roof manufactured according to the invention can be transported.

Det i fig. 1 viste tak er frittbærende og utformet som et såkalt «Hyppar»-skalltak. That in fig. 1 roof shown is free-supporting and designed as a so-called "Hyppar" shell roof.

Skalltaket er bare forankret til fun-damenter ved punktene a og b og er frittbærende ved punktene c og d. Belastnin-gen av taket vil forsøke å trykke punktene a og b fra hverandre, og fundamen-tene er derfor slik utformet og forankret at de er i stand til å oppta disse krefter. The shell roof is only anchored to foundations at points a and b and is free-supporting at points c and d. The load on the roof will try to push points a and b apart, and the foundations are therefore designed and anchored in such a way that they is able to absorb these powers.

Et slikt tak oppbygges først ved hjelp av bord, som strekker seg fra kantbj eiken b—d til kantbjeiken a—c. Disse bord har et nærmest rettlinjet forløp som antydet med linjene 1 i fig. 2. Over dette bordlag limes bord som strekker seg etter linjene 2 1 fig. 2 fra kantbjelken c—b til kantbj eiken aj—d. Det fremkommer altså to lag som er homogent forbundet med hverandre. Such a roof is first built up with the help of boards, which extend from the edge beams b—d to the edge beams a—c. These tables have an almost rectilinear course as indicated by the lines 1 in fig. 2. Above this board layer, boards are glued that extend along the lines 2 1 fig. 2 from the edge beam c—b to the edge bj spoke aj—d. This results in two layers that are homogeneously connected to each other.

Det er klart at det ikke er mulig å oppdele et på denne måte fremstilt skalltak i deler. It is clear that it is not possible to divide a shell roof produced in this way into parts.

I stedet for å holde bordene rettlinjet, som antydet ved linjene 1 og 2 i fig. 2, kan bordene også bøyes og anbringes da parallelt med linjene 3. Over disse bord kan det plaseres bord parallelt med linjene 4. De enkelte bord kan nå oppta kreftene i sin lengderetning. Instead of keeping the tables straight, as indicated by lines 1 and 2 in fig. 2, the tables can also be bent and placed parallel to the lines 3. Above these tables, tables can be placed parallel to the lines 4. The individual tables can now absorb the forces in their longitudinal direction.

Da det nå av samtlige etter linjene løpende bord oppbygges en flerlagig plate, og de to lag forbindes homogent med hverandre gjennom liming, kan denne plate oppta alle opptredende trykkrefter. As a multi-layer plate is now built up from all the boards running along the lines, and the two layers are connected homogeneously to each other through gluing, this plate can absorb all occurring pressure forces.

Denne plate er vist i den nedre del av fig. 3 og er festet til kantb jelkene 5 og 6. Platen består av et undre lag 7 og et øvre lag 8. Parallelt med linjene 4 (fig. 2) blir det på den første plate 7, 8 anordnet en annen plate, bestående av lagene 9 og 10. Også disse lag er forbundet homogent med hverandre gjennom liming. De to plater blir festet forskyvndngsfast, f. eks. ved nagling, på hverandre, idet også den av lagene 9, 10 bestående plate fast-settes på kantbjeikene. This plate is shown in the lower part of fig. 3 and is attached to the edge beams 5 and 6. The plate consists of a lower layer 7 and an upper layer 8. Parallel to the lines 4 (fig. 2), another plate is arranged on the first plate 7, 8, consisting of the layers 9 and 10. These layers are also connected homogeneously to each other through gluing. The two plates are secured against displacement, e.g. by riveting, on each other, as the plate consisting of the layers 9, 10 is also attached to the edge beams.

Når taket i det viste utførelseseksem-pel er ferdig oppbygget, vil den av lagene 7 og 8 bestående plate oppta trykkreftene og den av lagene 9 og 10 bestående plate oppta strekkreftene. When the roof in the embodiment shown is fully built, the plate consisting of layers 7 and 8 will absorb the compressive forces and the plate consisting of layers 9 and 10 will absorb the tensile forces.

Da takplatene består av flere lag er de formfaste. Platene kan oppdeles i deler, f. eks. i delene I og II. Oppdelingen kan foretas ved gjennomsagnlng, f. eks. ved delelinjen 11, eller idet bordene leg-ges mot hverandre. I det sistnevnte tilfelle kan bordene delvis overlappe hverandre, som vist ved delelinjen 12. As the roof panels consist of several layers, they are dimensionally stable. The plates can be divided into parts, e.g. in parts I and II. The division can be carried out by review, e.g. at the dividing line 11, or when the tables are placed against each other. In the latter case, the tables may partially overlap each other, as shown by the dividing line 12.

Da hver platedel består av flere lag, As each plate part consists of several layers,

er disse deler formfaste i seg selv. are these parts dimensionally stable in themselves.

Som det fremgår av fig. 4 kan plate-delene som skal danne det ferdige tak lett transporteres, og på byggestedet trenger bare kantbj eikene å anordnes i riktig stil-ling, hvorpå takdelene uten videre kan bringes på plass. As can be seen from fig. 4, the plate parts that will form the finished roof can be easily transported, and on the construction site only the edge braces need to be arranged in the correct position, after which the roof parts can be brought into place without further ado.
