Description
Anordning ved forbindelsesplater for trekonstruksjonsdeler. Device for connecting plates for wooden construction parts.
Denne oppfinnelse vedrorer forbindelsesplater for sammen-fbyning av trevirke og spesielt forbindelsesplater av den type som omfatter en metallplate som er stanset for å fremstille fremspring av hovedsakelig trekantet form som rager frem fra en side av platen og praktisk talt i rett vinkel med dens overflate. I bruk festes forbindelsesplatene på motstående sider av og tversover skjoten mellom trestykkene som de skal forbinde. This invention relates to connecting plates for joining wood and in particular to connecting plates of the type comprising a metal plate which is punched to produce protrusions of substantially triangular shape projecting from one side of the plate and practically at right angles to its surface. In use, the connecting plates are fixed on opposite sides of and across the joint between the pieces of wood that they are to connect.
Tidligere kjente forbindelsesplater består hovedsakelig av to typer, nemlig (a) en hvor en plan plate er stanset med spikerliknende fremspring over en dei av eller hele dens overflateareal, hvilke fremspring utforer en dobbelt funksjon ved å tilveiebringe motstand mot avskjæring og mot uttrekning av fremspringene hvilket ville resultere i brudd av forbindelsen, og (b) en hvor platen er stanset fra stålplate med uregulert plaserte korte fremspring formet spesielt for å motstå avskjæring, hvilken plate på sin side må festes til trevirket ved særskilte for hånd inndrevne spiker for å sikre riktig kontakt mellom platen og overflaten av trevirket som forenes. Previously known connecting plates consist principally of two types, namely (a) one in which a flat plate is punched with nail-like protrusions over some or all of its surface area, which protrusions perform a dual function of providing resistance to shearing and to pulling out of the protrusions which would result in breaking the joint, and (b) one where the plate is punched from steel plate with irregularly spaced short projections specially shaped to resist shearing, which plate in turn must be fixed to the wood by special hand-driven nails to ensure proper contact between the plate and the surface of the wood being joined.
Foreliggende oppfinnelse vedrbrer en forbindelsesplate forsammenfbyning av trevirke, spesielt takstoler og andre lastbærende bygningskonstruksjoner hvilken plate har korte fremspring eller spisser anordnet rundt et., staset hull, skåret ut langs linjer som fortrinnsvis, skjærer.hverandre og bbyet i rett vinkel mot minst en side og som« er buet i tverrsnitt svarende tii omkretsen av det stansede hull, og oppfinnelsen utmerker seg ved at platen også er forsynt med.et antall rektangulære, tynne og lange spikerliknende fremspring som likeledes er utstanset i platen og utbbyet i rett vinkel med platen. The present invention relates to a connecting plate for connecting wood, especially roof trusses and other load-bearing building structures, which plate has short protrusions or points arranged around a staggered hole, cut out along lines which preferably intersect each other and bent at right angles to at least one side and which" is curved in cross-section corresponding to the circumference of the punched hole, and the invention is distinguished by the fact that the plate is also provided with a number of rectangular, thin and long nail-like projections which are likewise punched in the plate and bent out at right angles to the plate.
De spikerliknende fremspring er fortrinnsvis formet med avskrånede spisser for derved å avbbye de spikerliknende fremspring svakt og., derved motstå uttrekning, av trevirket, og kan være forster-ket mot bbyning ved å være formet med en langsgående fordypning,f.eks. kan hvert spikerliknende fremspring være bbyd i tverretningen for å få en buet, V-formet eller annen kanalform.f The nail-like protrusions are preferably shaped with beveled tips in order to deflect the nail-like protrusions weakly and thereby resist pulling out of the wood, and can be reinforced against bending by being shaped with a longitudinal recess, e.g. each nail-like projection may be bent transversely to obtain a curved, V-shaped or other channel shape.f
Platene er fortrinnsvis fabrikert fra en rull av strimmel-formet metall som enten avskjæres i krevde lengder for å danne de individuelle plater eller utstyres med svekningslinjer for å mulig-gjøre at en stanset lengde av strimmelen kan holdes på lager og bry-tes av for å skaffe enkelte plater av busket lengde eller stbrrelse; for bruken. The sheets are preferably fabricated from a roll of strip-shaped metal which is either cut to required lengths to form the individual sheets or provided with lines of weakness to enable a punched length of strip to be kept in stock and broken off to obtain individual plates of bushy length or stem length; for use.
Forbindelsesplaten ifblge oppfinnelsen kan også være utstyrt med både korte og spikerliknende fremspring på begge overflater. The connection plate according to the invention can also be equipped with both short and nail-like protrusions on both surfaces.
Oppfinnelsen skal i det fblgende beskrives nærmere under hen-visning til tegningen hvor fig. 1. er et irontriss av en. utfbrelses-form av en forbindelsesplate av metall i henhold til oppfinnelsen, fig. Z et sideriss av fig. 1, fig. 3 et forstbrret per^spektivriss av fremspringene bak platesiden, fig. k et rammeverk (del av en tak-stol) som viser et typisk arrangement hvori forbindelsesplatene bru-kes for å forbinde tredeler, fig. 5 et snitt langs linjen V - V i fig. som viser en typisk buttskjbt, og fig. 6 et perspektivriss av en annen utforelse hvori fremspringene er anordnet på begge overflater av platen. The invention will be described in more detail in the following with reference to the drawing where fig. 1. is an iron triss of one. embodiment of a metal connecting plate according to the invention, fig. Z is a side view of fig. 1, fig. 3 is an enlarged perspective view of the protrusions behind the plate side, fig. k a framework (part of a roof truss) showing a typical arrangement in which the connecting plates are used to connect wooden parts, fig. 5 a section along the line V - V in fig. which shows a typical buttskjbt, and fig. 6 is a perspective view of another embodiment in which the protrusions are arranged on both surfaces of the plate.
I fig. 1 - 5 er en metallplate 1 som med mellomrom er utstyrt med stansede hull 2 for å fremstille trekantformede frem- In fig. 1 - 5 is a metal plate 1 which is equipped with punched holes 2 at intervals to produce triangular front-
spring k på en side hvilke fremspring bringer hullenes omkrets til spring k on one side which protrusions bring the circumference of the holes to
å være hovedsakelig av sirkulær form. Mellom noen av de stansede hull som danner de trekantede fremspring k er stanset spikerliknende fremspring 3 med storre lengde enn fremspringene k og som hvert er formet med en avstivningsfordypning 12 i lengderetningen og ender med en avskrånet spiss 13. Både de trekantede og de spikerliknende fremspring strekker seg i rett vinkel fra en overflate av platen. being mainly circular in shape. Between some of the punched holes that form the triangular protrusions k are punched nail-like protrusions 3 with a greater length than the protrusions k and each of which is shaped with a stiffening recess 12 in the longitudinal direction and ends with a beveled tip 13. Both the triangular and the nail-like protrusions extend itself at right angles from one surface of the plate.
Fig. 2 viser forholdet mellom de korte trekantformede fremspring k og de langs spikerliknende fremspring 3, av hvilke de fbrste fremspring tilveiebringer motstand mot overflateglidning og de spikerliknende fremspring vedlikeholder overflatekontakt mellom metall-""-platen og trestykkene. Fig. 3 viser et perspektivriss av fremspringene k av et av de stansede hull 2 og en av spikerne 3. Fig. 2 shows the relationship between the short triangular projections k and the longitudinal nail-like projections 3, of which the first projections provide resistance to surface sliding and the nail-like projections maintain surface contact between the metal "" plate and the wooden pieces. Fig. 3 shows a perspective view of the projections k of one of the punched holes 2 and one of the nails 3.
Forbindelsesplaten ifblge oppfinnelsen tilveiebringer en hby grad av skjærutvikling i alle retninger av treets fibre som folge av de korte trekantformede fremspring k, og de i ett med platen ut-formede spikerliknende fremspring 3 vedlikeholder den viktige kontakt mellom overflaten. Disse spikerliknende fremspring, som er mindre i antall enn hvis de også skulle tilveiebringe hele motstan-den mot avskjæring eller forskyvning, tilveiebringer derfor mindre svekkelse av trevirket ved perforering enn ved tidligere konstruk-sjoner. The connecting plate according to the invention provides a high degree of shear development in all directions of the wood's fibers as a result of the short triangular projections k, and the nail-like projections 3 formed in one with the plate maintain the important contact between the surface. These nail-like protrusions, which are smaller in number than if they were also to provide the entire resistance to cutting or displacement, therefore provide less weakening of the wood by perforation than with previous constructions.
Kjente plater av den forannevnte type (a) må festes i stil-ling ved bruk av presser av den type som har vertikalt pressebord da det ikke er mulig som folge av fremspringenes lengde, å feste disse plater under anvendelse av ea,_.presse ay valsetypen. Known plates of the aforementioned type (a) must be fixed in position using presses of the type that have a vertical press table, as it is not possible, as a result of the length of the protrusions, to fix these plates using a press ay the roller type.
De kjente plater av type (b) kan påfbres ved en av de nevnte pressetyper men innebærer den ulempe at de enkelte plater må fast-,-, spikres for hånd på treverkets begge sider. The known plates of type (b) can be applied by one of the mentioned press types, but this entails the disadvantage that the individual plates must be fixed, nailed by hand on both sides of the wood.
Platene ifblge oppfinnelsen kan, skjbnt de er ideelle for bruk med en vertikal tryMqpresse, også brukes vedban valseprésse ved ■ delvis inndrivning av de lange spikerliknende fremspring med en ham-mer for valsingen. The plates according to the invention, although they are ideal for use with a vertical printing press, can also be used with a rolling press by ■ partially driving in the long nail-like protrusions with a hammer for the rolling.
Et trekk ved platen ifblge oppfinnelsen, er (fens evne til å frembringe belastningsmbnstret i en hvilken som helst retning av fibrene med forbundet effektivitet, de trekantformede fremspring rundt omkretsen av de sirkulære utstansninger tilveiebringer bety-delig motstand mot glidning (skjæring) på treverkets overflate på grunn av at et stort areal av platen til enhver tid vil være i kontakt med ethvert fibermateriale som frembringer den stbrste motstand mot glidning. A feature of the plate according to the invention is its ability to provide load support in any direction of the fibers with associated efficiency, the triangular protrusions around the circumference of the circular punches provide significant resistance to sliding (cutting) on the surface of the wood on due to the fact that a large area of the plate will at all times be in contact with any fibrous material which produces the strongest resistance to sliding.
En annen ting med hensyn til strukturen av selve tremateri-alet er at spikerliknende fremspring taper deres effektivitet ved reduserte belastningsfaktorer og en tendens til å splitte jo nærmere de er plasert endene eller kantene av trevirket, som skal for-bindes eller skjotes. Faktorere påvirkes mere ved dybden av inn-trengning enn ved svakheten av materialet og maksimal fordel oppnåes ved å frembringe skjærmotstand nær trevirkets overflate, spesielt nær enden eller kanten og oppnåes med en plate ifblge oppfinnelsen. Another thing with regard to the structure of the wood material itself is that nail-like protrusions lose their effectiveness at reduced load factors and tend to split the closer they are placed to the ends or edges of the wood to be joined or spliced. Factors are affected more by the depth of penetration than by the weakness of the material and maximum benefit is achieved by producing shear resistance near the surface of the wood, especially near the end or edge and is achieved with a plate according to the invention.
Virkningen av de lange spikerliknende fremspring er begren-set til å vedlikeholde kontakt mellom platen og trevirket for å frembringe maksifftl kraftoverfbring tversover skjoten. De avskrånede spisser 13 på de lange spikerliknende fremspring 3 sbker å avbbye disse fremspring når de drives inn i trevirket og medvirker derved til å motstå uttrekning og således vedlikeholde maksimum overflatekontakt. Avskråningen kan orienteres i motsatte retninger på fremspringene 3 således at par av disse fremspring vil avbbyes i motsatte retninger for videre medvirkning til å hindre uttrekning. The effect of the long nail-like protrusions is limited to maintaining contact between the board and the wood in order to produce maximum force transmission across the joint. The beveled tips 13 on the long nail-like projections 3 tend to deflect these projections when they are driven into the wood and thereby help to resist pulling out and thus maintain maximum surface contact. The bevel can be oriented in opposite directions on the projections 3 so that pairs of these projections will be deflected in opposite directions to further contribute to preventing extraction.
Den av et antall bestående sirkulære utstansriinger avstiver platen The one of a number of circular cutouts stiffens the plate
i lengden og bredden o^'fijbr at dens motstandsdyktighet mot uttrekning bæres ay alle kontaktpunkter. in the length and width o^'fijbr that its resistance to withdrawal is carried ay all contact points.
Fig. 6 viser en annen utfbrelse hvori platen i ex- utstyrt med trekantedefremspring ' i o;; spikerliknende fremspring 3 på Degge overila t.er. Ved bruk aiiMlnyos denne pla te in cl lo in to tre s tykker for a feste disse side mo t side, unton platen s trekker seg over en skjot mellom to tilgrensende trestykker"på en eller begge sider av flaten eller ei. Fig. 6 shows another embodiment in which the plate i ex- equipped with triangular projections ' i o;; nail-like projections 3 on Degge overila t.er. When using aiiMlnyos this plate in cl lo in two wood s thick to fasten these side by side, unton the plate s pulls over a joint between two adjacent pieces of wood"on one or both sides of the surface or not.
Det vil forståes at forskjellige endringer kan foretas. således kan f. eks. hver l hull 2 stanses for å da/me et spikerliknende fremspring j så veJ. som et antall korte f r ein spring k. i stedet for at spissene på spikerliknende fremspring er avskrådd kan de lia pii-spissliknende ender. It will be understood that various changes may be made. thus, e.g. each l hole 2 is punched to give a nail-like projection j so veJ. as a number of short f r ein spring k. instead of the tips of nail-like protrusions being bevelled, they may have pii-tip-like ends.
