Description
Oppfinnelsen vedrorer et gitterverk for sideveis å understøtte The invention relates to a latticework for lateral support
en bunt langstrakte komponenter som forloper gjennom åpninger i gitterverket og deltar i en varmevekslingsprosess, spesielt kjernekraft-brennstoffelementer, hvor gitterverket er sammen- a bundle of elongated components that run through openings in the grid and participate in a heat exchange process, especially nuclear fuel elements, where the grid is con-
satt av to kryssende sett av innbyrdes parallelle bånd som forloper på samme nivå, og som er forsynt med kamliknende uttagninger som forloper over en halvdel av båndbredden, hvor nevnte bånd er koblet sammen med hverandre ved deres krysningspunkter ved hjelp av fire utadboyde festelepper. composed of two intersecting sets of mutually parallel bands running at the same level, and which are provided with comb-like recesses running over one-half of the band width, said bands being connected to each other at their crossing points by means of four outwardly curved attachment lips.
Gitterverk av dette slag har tidligere vist seg å være så kom-pliserte å fremstille at den tid som kreves, har gjort dem me- Lattices of this kind have previously proved to be so complicated to produce that the time required has made them me-
get kostbare. get expensive.
Ifolge oppfinnelsen foreslås at det innledningsvis nevnte gitterverk utfores slik at hvert bånd er forsynt med to slike lepper delvis stanset ut av båndet ved motsatte kanter av dette, og at leppene er boyd utad i motsatte retninger, hver i plan direkte tilliggende motsatte vegger av den kamliknende uttagning på en slik måte at den ene leppen ved den motsatte kant av kamstrimmelen enn uttagningen er lenger enn leppen som er plassert ved den andre kanten. According to the invention, it is proposed that the grid work mentioned at the outset be made so that each band is provided with two such lips partially punched out of the band at opposite edges thereof, and that the lips are bowed outwards in opposite directions, each in plane directly adjacent to opposite walls of the comb-like recess in such a way that one lip at the opposite edge of the comb strip from the recess is longer than the lip located at the other edge.
Ved hjelp av disse festelepper blir de innbyrdes kryssende bånd festet til hverandre. Den mest hensiktsmessige befestigelse fåes ved at befestigelsen av en leppe til et kryssende bånd skjer ved hjelp av punktsveising. With the help of these fastening lips, the mutually crossing bands are attached to each other. The most suitable fastening is achieved by the fastening of a lip to a crossing band using spot welding.
På denne måte blir det mulig å bygge opp et gitterverk ved hjelp av en enkel sveiseprosess, mens samtidig antall deler kan holdes forholdsvis lavt sammenlignet med vanlige punktsveisekonstruk-sjoner i hvilke strimlene eller båndene forenes med hverandre ved hjelp av U-formede forbindelsesstykker. Disse forbindelsesstykker har videre i praksis vist seg å medfore en ulempe ved at de lett blir boyet ut av form. In this way, it becomes possible to build up a grid using a simple welding process, while at the same time the number of parts can be kept relatively low compared to normal spot welding constructions in which the strips or bands are joined to each other by means of U-shaped connecting pieces. These connecting pieces have also been shown in practice to cause a disadvantage in that they are easily bent out of shape.
Den mest praktiske måte for å bringe disse kamliknende strimler til å gripe inn i hverandre på en slik måte at festepunktene for punktsveising blir liggende ovenfor hverandre, oppnås hvis leppene for en kamstrimmel ved motsatt beliggende kanter boyes utover i motsatte retninger. Dette skjer best ved at motsatt beliggende lepper boyes utover i plan som ligger direkte på veggene for et kamliknende innsnitt. The most practical way of bringing these comb-like strips to engage each other in such a way that the attachment points for spot welding lie above each other is achieved if the lips of a comb strip at opposite edges are bent outwards in opposite directions. This is best done by bending the opposite lips outwards in a plane that lies directly on the walls for a comb-like incision.
For å sikre at den overflate som er til disposisjon for befestigelse, fortrinnsvis ved punktsveising er stor nok i alle stillin-ger, gjores leppene lengre ved den ene kant av kamstrimmelen enn leppene på den annen kant. To ensure that the surface that is available for fastening, preferably by spot welding, is large enough in all positions, the lips are made longer at one edge of the comb strip than the lips on the other edge.
Det har vist seg at kamstrimler fremstilt på denne måte har en form således at samme slags strimler er tjenlige for alle båndene som anbringes i det indre av et gitterverk. It has been found that comb strips produced in this way have a shape such that the same kind of strips are useful for all the bands placed in the interior of a lattice work.
Sammenbyggingen tilveiebringes ved at i det minste to sett av innbyrdes parallelle kamstrimler skyves inn i hverandre på en slik måte at kamstrimlene for det ene sett, som alle er parallelle med hverandre, anbringes motsatt kamstrimlene for det annet sett. I et sett vil således de lange, utadboyede lepper ligge ved toppkanten, mens for det andre sett vil disse lepper ligge ved strimmelens bunnkant. The assembly is provided by at least two sets of mutually parallel comb strips being pushed into each other in such a way that the comb strips for one set, which are all parallel to each other, are placed opposite the comb strips for the other set. In one set, the long, outwardly curved lips will thus lie at the top edge, while for the other set these lips will lie at the bottom edge of the strip.
I det etterfblgende skal oppfinnelsen beskrives nærmere i for-bindelse med en typisk utforelsesform illustrert ved tegningene. In what follows, the invention will be described in more detail in connection with a typical embodiment illustrated by the drawings.
Fig. 1, 2 og 3 viser perspektivisk to innbyrdes kryssende bånd, hvilke sees sammenbygget i fig. 3 og i atskilt stilling i fig. Fig. 1, 2 and 3 show in perspective two mutually crossing bands, which can be seen assembled in fig. 3 and in a separate position in fig.
1 og 2. 1 and 2.
Fig. 1 viser en del av et kryssbånd slik dette er utformet på det sted hvor det krysser et kantbånd 2 (se fig. 2). De kryssbånd som heretter også er betegnet kamstrimler, er forsynt med lange, utoverbbyete lepper 4. Leppene 3 og 4 er anbragt på motsatte sidekanter 5 og 6 av kamstrimmelen og er også bbyete utover i forskjellige retninger. De lange lepper 3 tilveiebringer ved sin utadbbyning uttagninger 7 og de korte lepper 4 tilveiebringer uttagninger 8. Fra denne uttagning 8 forer en uttagning 9 opp i båndet. Denne sistnevnte uttagning har en bredde som nbyaktig svarer til det annet bånds tykkelse. Fig. 1 shows part of a cross band as it is designed at the place where it crosses an edge band 2 (see Fig. 2). The cross bands, which are hereafter also referred to as comb strips, are provided with long, outwardly curved lips 4. The lips 3 and 4 are placed on opposite side edges 5 and 6 of the comb strip and are also curved outwards in different directions. The long lips 3 provide, by their opening, recesses 7 and the short lips 4 provide recesses 8. From this recess 8, a recess 9 leads up into the belt. This latter cut-out has a width that roughly corresponds to the thickness of the second band.
Ved å sammenholde fig. 1 og 2, vil det sees at fig. 2 har prin-sipielt samme form som kamstrimmelen i fig. 1, men er et omvendt bilde av denne. Fig. 3 viser hvorledes det er mulig å bringe strimlene ifblge fig. 1 og 2 til å passe inn i hverandre ved å fore strimmelen 1 nedover kamstrimmelen 2. Da den lange utoverbbyete leppe som strekker seg gjennom uttagningen 8 for strimmelen 2, er bbyet mot venstre, fåes en festeflate 10 mellom innsiden 11 av leppen 3 og delen 12 på strimmelen 2. Samtidig dannes en andre festeposisjon mellom leppen 13 for strimmelen 2 og delen 14 av strimmelen 1. Fblgelig er det også mulig å til-veiebringe punktsveiseforbindelse ved 15 såvel som ved 12. Det samme gjelder befestigelsesstillingene på undersiden 16 av krysningspunktet. By comparing fig. 1 and 2, it will be seen that fig. 2 has basically the same shape as the comb strip in fig. 1, but is an inverted image of this. Fig. 3 shows how it is possible to bring the strips according to fig. 1 and 2 to fit into each other by guiding the strip 1 down the comb strip 2. As the long outwardly curved lip that extends through the recess 8 for the strip 2 is curved to the left, a fastening surface 10 is obtained between the inside 11 of the lip 3 and the part 12 on the strip 2. At the same time, a second attachment position is formed between the lip 13 for the strip 2 and the part 14 of the strip 1. Accordingly, it is also possible to provide a spot welding connection at 15 as well as at 12. The same applies to the attachment positions on the underside 16 of the crossing point.
, På denne måte kan fire punktsveisesteder fåes for hvert skjærings-punkt for et sett av kamstrimler , slik at man får en meget solid konstruksjon. , In this way, four spot welding locations can be obtained for each intersection point for a set of comb strips, so that a very solid construction is obtained.
