Description
Den foreliggende oppfinnelse vedrører en bueforme for anvendelse ved bygging av hvelvinger. The present invention relates to an arch form for use in the construction of vaults.
En bueforme som har vist seg meget vellykket, er kjentAn arch form which has proved very successful is known
fra GB-patentskrift 1.590.298, og er i en modifisert utførelses-form beskrevet i europeisk patentsøknad 81305476-4. Det er solgt mange slike bueformere som er fremstilt av flatt strekkmetall av liten maskevidde og som er egnet for anvendelse sammen med finfraksjons-gips. Det er imidlertid et behov for bueformere som er egnet for grovfraksjons-gips og det er konstatert at grovfraksjons-gips ikke vil vedhefte tilfredsstillende til finmasket strekkmetall. from GB patent 1,590,298, and is in a modified embodiment described in European patent application 81305476-4. Many such arch formers have been sold, which are made of flat expanded metal of small mesh size and which are suitable for use together with fine-fraction gypsum. There is, however, a need for arch formers that are suitable for coarse fraction plaster and it has been established that coarse fraction plaster will not adhere satisfactorily to fine-mesh tensile metal.
Det er av den grunn blitt eksperimentert med grovmasket strekkmetall med åpninger som har en største lengde av 6-9 mm og en største bredde av 3-5 mm, f.eks. 7,87 x 3,81 mm med en strengbredde av 1,52 mm og en -tykkelse av 0,6 mm. Dette har vist seg å være tilfredsstillende for gipsmaterialet. Experiments have therefore been carried out with coarse-mesh expanded metal with openings that have a maximum length of 6-9 mm and a maximum width of 3-5 mm, e.g. 7.87 x 3.81 mm with a strand width of 1.52 mm and a thickness of 0.6 mm. This has proven to be satisfactory for the plaster material.
Det var imidlertid umulig å tilvirke bueformere ved anvendelse av vanlige metoder, f.eks. på en Pittsburgh-maskin, fordi de kappete ender ble fastsittende i maskinen. However, it was impossible to manufacture bow formers using common methods, e.g. on a Pittsburgh machine, because the cut ends got stuck in the machine.
Dette har nødvendiggjort en fullstendig nytenkning og det er, over et tidsrom av 18 måneder, utført tallrike, mislykkete eksperimenter som har kostet flere tusen pund, i bestrebelser på å fremstille bueformere av grovmasket strekkmetall. Bukling av metallet var årsak til mye besvær, da det er vanskelig å ut-forme flenser på krumme kanter. Massivt metallblikk ble også forsøkt brukt, men uten hell. This has necessitated a complete rethink and, over a period of 18 months, numerous, unsuccessful experiments have been carried out, costing several thousand pounds, in efforts to produce arch formers from coarse-mesh expanded metal. Buckling of the metal caused a lot of trouble, as it is difficult to design flanges on curved edges. Solid sheet metal was also tried, but without success.
Det er nå utviklet en fremgangsmåte som er velegnet for produksjon i stor målestokk. A method has now been developed which is suitable for production on a large scale.
Ifølge den foreliggende oppfinnelse er det frembrakt en bueformer med fire identiske deler som hver for seg omfatter According to the present invention, a bow former has been produced with four identical parts which each separately comprise
a) en vertikalvegg med en bueformet underkant som er omgitt a) a vertical wall with an arched lower edge which is surrounded
av en horisontal flens,of a horizontal flange,
b) en bueformet horisontalvegg som forløper rettvinklet mot vertikalveggen, og c) en kantvulst med et oppadragende parti rundt vertikalveggens underkant, som kjennetegnes ved at horisontalveggens b) an arc-shaped horizontal wall that extends at right angles to the vertical wall, and c) an edge bead with a rising part around the lower edge of the vertical wall, which is characterized by the horizontal wall's
randsone er beliggende under vertikalveggens flens, og at kantvulsten innbefatter en glatt, plan flens som forløper mellom vertikalveggens flens og horisontalveggens randsone, og edge zone is located below the flange of the vertical wall, and that the edge bead includes a smooth, flat flange that extends between the flange of the vertical wall and the edge zone of the horizontal wall, and
at flensene og randsonen er sammenføyd med et antall gjennomgående kramper. that the flanges and the edge zone are joined with a number of continuous crampons.
Oppfinnelsen vil bli nærmere beskrevet i det etterfølgende under henvisning til de medfølgende tegninger, hvori: Fig. 1 viser et perspektivriss av en bueformer ifølge oppfinnelsen, hvor imidlertid kantvulsten er utelatt. Fig. 2 viser et perspektivriss av en av de fire deler. Fig. 3 viser et riss som illustrerer en fremgangsmåte til utforming av en flens. The invention will be described in more detail below with reference to the accompanying drawings, in which: Fig. 1 shows a perspective view of a bow former according to the invention, where, however, the edge bead is omitted. Fig. 2 shows a perspective view of one of the four parts. Fig. 3 shows a diagram illustrating a method for designing a flange.
Bueformeren består av fire identiske deler 10 som hver omfatter en plan vertikalvegg 11 med bueformet underkant 12 The arch former consists of four identical parts 10, each of which comprises a flat vertical wall 11 with an arched lower edge 12
som er forbundet med en bueformet horisontalvegg 13 som forløper rettvinklet mot vertikalveggen. Disse vegger er tilvirket av flatt strekkmetall som i et spesielt tilfelle har åpningsdimensjoner 7,87 mm x 3,81 mm. Istedenfor en randdeformasjon innbefatter veggen 13 en randsone 19 som er beliggende i plan med resten av veggen og derved forløper parallelt med og under flensen . which is connected by an arc-shaped horizontal wall 13 which extends at right angles to the vertical wall. These walls are made of flat expanded metal which in a special case has opening dimensions of 7.87 mm x 3.81 mm. Instead of an edge deformation, the wall 13 includes an edge zone 19 which is located flush with the rest of the wall and thereby runs parallel to and below the flange.
Vertikalveggens underkant går over i en horisontal flens 16. The lower edge of the vertical wall merges into a horizontal flange 16.
En kantvulst 20 omfatter et kort, bueformet veggparti 23 som omgir underkanten av veggen 11, og et horisontalt underparti 22, et kortere vertikalt parti 21 og en horisontal flens 24 som er meget kortere enn før og anordnet i form av en glatt, plan flens (dvs. ikke tilbakefoldet over seg selv slik som tidligere). Flensen 24 befinner seg mellom flensen 16 og randsonen 19. An edge bead 20 comprises a short, arc-shaped wall part 23 which surrounds the lower edge of the wall 11, and a horizontal lower part 22, a shorter vertical part 21 and a horizontal flange 24 which is much shorter than before and arranged in the form of a smooth, flat flange ( i.e. not folded back over itself as before). The flange 24 is located between the flange 16 and the edge zone 19.
Flensene 16 og 24 og randsonen 19 er sammenstiftet medThe flanges 16 and 24 and the edge zone 19 are stapled together with
to rekker av kramper 26 ved hjelp av en såkalt stiftemaskin. Dette har vist seg å være enklere enn den tidligere anvendte punktsveising, og derved unngås den korrosjon som opptrer ved punktsveising, og det er ingen punktsveiser som må overmales. Krampene i den ene rekke kan være forskjøvet i forhold til kram- two rows of staples 26 using a so-called stapling machine. This has proven to be simpler than the previously used spot welding, thereby avoiding the corrosion that occurs with spot welding, and there are no spot welds that need to be painted over. The cramps in one row may be shifted in relation to the cramp-
pene i den annen rekke.pretty in the second row.
Flensen 16 er opprettet på en bueformet kant 12, og dette medfører visse vanskeligheter, men er gjennomført ved at de to plater 10 og 11 plasseres mellom to klemplater 28 og 29 (fig. 3) med motsvarende bueflater 30 og 31. Platenes 10 og 11 randsoner som rager ut over bueflåtene 30 og 31, åpnes utad og flat-trykkes mot bueflåtene 30 og 31 ved hjelp av en valse 35. The flange 16 is created on an arc-shaped edge 12, and this entails certain difficulties, but is accomplished by placing the two plates 10 and 11 between two clamping plates 28 and 29 (fig. 3) with corresponding arc surfaces 30 and 31. The plates 10 and 11 edge zones that protrude above the bow rafts 30 and 31 are opened outwards and pressed flat against the bow rafts 30 and 31 by means of a roller 35.
Vulsten 20 er fremstilt av småmasket, flatt strekkmetall,The bead 20 is made of fine-mesh, flat expanded metal,
og dette utføres som tidligere på en Pittsburgh-falsemaskin med flensbøyerhjul som atskiller seg fra dem som anvendes på en Pittsburgh-f alsskjøt-formermaskin. Åpningene i vulsten kan ha dimen-sjoner av 3-4 mm x 1,5-2,5 mm, eksempelvis 3,18 x 2,03 mm x 0,79 strengbredde x 0,6 mm strengtykkelse. and this is carried out as before on a Pittsburgh folding machine with flange bending wheels different from those used on a Pittsburgh folding joint forming machine. The openings in the bead can have dimensions of 3-4 mm x 1.5-2.5 mm, for example 3.18 x 2.03 mm x 0.79 strand width x 0.6 mm strand thickness.
Delene kan fremstilles av materiale med tett, galvanisk ytterbelegg. The parts can be made of material with a tight, galvanic outer coating.
