Description
Knutepunktforbindelse for trekonstruksjoner. Node connection for wooden constructions.
Oppfinnelsen vedrører en knutepunktforbindelse for trekonstruksjoner med en notforsynt gurt og to strebere som er forbundet innbyrdes samt med gurten ved hjelp av sammenliming, hvorved det ved hjelp av endene til hosliggende strebere dannes minst en i en gurtnot inntredende tapp, hvor streberendene fortrinnsvis er forbundet med hverandre, ved hjelp av minisinker. The invention relates to a node connection for wooden constructions with a grooved girth and two struts which are connected to each other and to the girdle by means of gluing, whereby at least one pin entering a girth groove is formed with the help of the ends of adjacent struts, where the strut ends are preferably connected to each other , using mini sinks.
Knutepunktforbindelser av denne type er tidligere kjent og har den fordel at de har relativt store limflater og dermed også en stor bæreevne. Node connections of this type are previously known and have the advantage that they have relatively large adhesive surfaces and thus also a large load-bearing capacity.
Da sammenlimingen, av slike forbindelser bestandig skjer uten tverrpress, har nå imidlertid de kjente utførelser den vesent-lige ulempe at kappenes tykkelse må tilsvare notbredden med en nøyak-tighet som bare vanskelig er oppnåelig ved trebearbeidelse'uten at det treffes spesielle tiltak. As the gluing of such connections always takes place without transverse pressure, the known designs now have the significant disadvantage that the thickness of the sheaths must correspond to the groove width with an accuracy that is only difficult to achieve in woodworking without special measures being taken.
Også den kjente -kileforsinking kan ikke fjerne denne ulempe, idet de ved de enkelte sinker opptredende tverrtrykk i det vesent-lige opphever hverandre <p>g innpasningens nøyaktighet bare kan unngås f. eks. ved anvendelsen av todelte gurter. Bortsett fra dette fører den nødvendige sinkebredde til tilsvarende brede gurter eller til en avgjørende reduksjon av limflaten. Even the known -wedge countersinking cannot remove this disadvantage, as the transverse pressures occurring at the individual counters essentially cancel each other <p>g the accuracy of the fit can only be avoided, e.g. when using two-part belts. Apart from this, the required zinc width leads to correspondingly wide belts or to a decisive reduction of the adhesive surface.
Videre er det kjent å forbinde de to gurter med hverandre ved hjelp av en skaftforbindelse. Med denne forbindelse kan det rik-tignok med hensyn til limflaten og bæreevnen oppnås resultater som i hvert fall er likeverdige med kileforsinkingen, uten at det derved er nødvendig å underskride de vanlige toleranser ved trebearbeidelse for tapp- og notbredden. Denne løsning har imidlertid den ulempe at streberendene, betinget av skaftforbindelsen, nødvendiggjør en komplisert bearbeidelse. Furthermore, it is known to connect the two belts with each other by means of a shaft connection. With this connection, with respect to the adhesive surface and the load-bearing capacity, results can be achieved that are at least equivalent to the wedge delay, without it being necessary to thereby fall below the usual tolerances in woodworking for the tenon and groove width. However, this solution has the disadvantage that the strut ends, conditioned by the shaft connection, require complicated processing.
Ved alle disse kjente forbindelser skjer sammenlimingen av streberendene, henholdsvis tappene tii streberne med gurtene utelukk-ende over sideflatene til de nevnte deler, mens endeflatene ikke bi-drar til forbindelsen. In all of these known connections, the joining of the strut ends, respectively the pins of the struts with the belts, takes place exclusively over the side surfaces of the parts mentioned, while the end surfaces do not contribute to the connection.
Hensikten med oppfinnelsen er å tilveiebringe en knutepunktforbindelse av den innledningsvis nevnte type, som er overlegen i forhold til de kjente såvel med hensyn til limflate som også bære-kraft og også i fremstilling, hvor også endeflatene til streberendene og tappene benyttes til kraftoverføring. The purpose of the invention is to provide a junction connection of the type mentioned at the outset, which is superior to the known ones both with regard to the adhesive surface as well as bearing capacity and also in manufacturing, where the end surfaces of the struts and pins are also used for power transmission.
Denne hensikt blir oppnådd ifølge oppfinnelsen ved at tappen er forbundet med gurten ved hjelp av i notbunnen til noten samt på endeflaten til den i noten inntredende tapp anordnede minisinker. Fordelaktig inneslutter den mot notbunnen vendte flate av streberenden med endeplaten til den samme en vinkel a mindre enn 90°. Ved hjelp av minisinkene på endeflaten mellom gurten og tappen til streberen blir det ikke bare oppnådd en bedre fastholding av denne i gurten mot uttrekning, men fremfor alt også oppnådd en øking av for-bindelsens stivhet på en slik måte at ved innvirkning av en enkeltlast mellom strebertilslutningene at gurtdelene er mer motstandsdyktige. Det er derved også mulig på undergurten til en slik fremstilt bærer å la krefter innvirke som belaster hele bæreren på bøyning. Minisinkene mellom streberendene bringer videre den fordel at limflatene mellom disse er 60 % større enn limflatene ved kileforsinking. For det and-re, er limflaten mellom tappen til streberen og gurten 25 - 30 % stør-re pr. tapp enn den ved skaftforbindelse mellom streberendene. This purpose is achieved according to the invention by the pin being connected to the girth by means of mini-sinks arranged in the groove bottom of the groove and on the end surface of the pin entering the groove. Advantageously, the surface of the strut end facing the bottom of the groove includes with the end plate of the same an angle a of less than 90°. With the help of the mini-sinks on the end surface between the belt and the pin of the strut, not only is a better retention of this in the belt against pull-out achieved, but above all also an increase in the stiffness of the connection is achieved in such a way that upon impact of a single load between the connections strive that the belt parts are more resistant. It is thereby also possible to allow forces to act on the lower belt of such a manufactured carrier which stress the entire carrier in bending. The mini-sinks between the ends of the struts also bring the advantage that the adhesive surfaces between these are 60% larger than the adhesive surfaces in case of wedge countersinking. Secondly, the adhesive surface between the pin of the strut and the belt is 25 - 30% larger per taper than that at the shaft connection between the strut ends.
Oppfinnelsen er i det følgende nærmere forklart ved hjelp av et utførelseseksempel som er fremstilt på tegningen, som viser: The invention is explained in more detail in the following with the help of an embodiment shown in the drawing, which shows:
fig. 1 et snitt parallelt til streberplanet langs linjen fig. 1 a section parallel to the strike plane along the line
I - I på fig. 3, I - I in fig. 3,
fig. 2 et snitt langs linjen II - II på fig. 1 og fig. 3 et snitt langs linjen III - III på fig. 1. fig. 2 a section along the line II - II in fig. 1 and fig. 3 a section along the line III - III in fig. 1.
I det viste utførelseseksempel er endene til streberparene betegnet med 1, henholdsvis 2 og gurten med 3. Hver streberende har to sinker la og lb, henholdsvis 2a og 2b, som er begrenset av hver gang to til streberplanet og dermed til sideveggene til gurtnotene 4 parallelle ytterflater 6 og et endeplan 8. På endeplanet 8 er det anbragt en miniforsinking 75 som har en dybde på ca. 7 nir.: og en spiss-avstand på ca. 2 mm. De overfor hverandre liggende sinker til de to strebere danner en i en av de halvmåneformede noter til gurten inn-passende tapp, hvorved sinkene med sine med miniforsinking 7 utstyrte endeplan 8 vil ligge på hverandre. Selvfølgelig kan sinkene imidlertid også være forbundet med hverandre ved hjelp av en av^ de kjente forbindelsestyper. In the embodiment shown, the ends of the brace pairs are denoted by 1, respectively 2 and the girth by 3. Each girder has two sinkers la and lb, respectively 2a and 2b, which are limited by each time two to the girder plane and thus to the side walls of the girth notches 4 parallel outer surfaces 6 and an end plane 8. On the end plane 8 is placed a mini countersinking 75 which has a depth of approx. 7 nir.: and a tip distance of approx. 2 mm. The countersunks of the two struts form a fitting pin in one of the half-moon-shaped grooves of the girth, whereby the sinkers with their end planes 8 equipped with mini countersinking 7 will lie on top of each other. Of course, however, the zincs can also be connected to each other by means of one of the known connection types.
I notbunnen til de halvmåneformede noter 4 til gurten 3 er det en miniforsinking 93 som svarer til miniforsinkingen 7 på streberendene. -På endeflaten til tappen til de to strebere blir det i bue-form - omtrent etter skjemaet til en kopifreser - utformet en motfor-sinking til den på bunnen til noten 4 anordnede miniforsinking. Den mot motbunnen i hver not vendte flate 5 til tappene på streberendene 1, 2 inneslutter for å oppnå en bedre tilpassing til formen til notbunnen en vinkel a til notbunnen mindre enn 90° med endeflatene 8 til streberendene 1, 2. In the groove base of the crescent-shaped grooves 4 of the girth 3, there is a mini countersinking 93 which corresponds to the mini countersinking 7 on the strut ends. - On the end surface of the pin of the two struts, a counter-countersinking is designed in an arched shape - roughly according to the scheme of a copy milling cutter - to the mini-sinking arranged on the bottom of the note 4. In order to achieve a better adaptation to the shape of the groove bottom, the surface 5 of the tabs on the strut ends 1, 2 facing the opposite bottom in each groove encloses an angle a to the groove bottom less than 90° with the end surfaces 8 of the strut ends 1, 2.
De to streberendene 1 og 2 blir for dannelsen av to tapper som består av en sinke fra hver streberende skjøvet mot hverandre og tappene innsettes i de to noter til gurten 3 etter at notveggene samt ytterflåtene 6 og minisinkene 7} 9 på forhånd er påstrøket et egnet lim. The two strut ends 1 and 2 are pushed towards each other to form two studs consisting of a sinker from each strut and the studs are inserted into the two grooves of the girth 3 after the groove walls as well as the outer rafts 6 and the mini sinkers 7} 9 have previously been coated with a suitable glue.
Ved hjelp av knutepunktforbindelsen ifølge oppfinnelsen blir det oppnådd et særlig gunstig snittpunkt for kraftlinjene til streberne med 0-fasen til gurten. With the help of the node connection according to the invention, a particularly favorable point of intersection is achieved for the lines of force of the struts with the 0 phase of the girth.
Oppfinnelsen er også anvendbar med de samme fordeler for tre tapper eller bare en tapp pr. streberpar. The invention is also applicable with the same advantages for three pins or only one pin per striving couple.
Av oversiktsgrunner ble i lengdesnitt de på grunn av kile-. forsinkingen skrå flater skravert i fiberretning. Ved .krysningen av denne skravering er kileforsinkingstilslutningene tydelig synlige. For reasons of overview, they were in longitudinal section because of wedge-. the delay inclined surfaces shaded in fiber direction. At the intersection of this shading, the wedge delay connections are clearly visible.
