Description
Forlengelsen, av betongpåler roed en. skjøt som tålerThe extension, of concrete piles roed en. joint that withstands
et moment, er i> de seneste år blrtt mer og mer a,lm.innel£g.a moment, in recent years is more and more a,lm.innel£g.
På grunn av de ;meget store varierende spenninger som oppstår under slagene, i* forhold til konstruksjonens statiske last, Due to the very large varying stresses that occur during the blows, in relation to the static load of the structure,
har det også forekommet vanskeligheter ved utførelsen av pålingsarbeidet med hensyn tiNl de for anvendelse godkjente typer forlengelse. there have also been difficulties in carrying out the piling work with regard to the types of extension approved for use.
De vesentligste "vanskeligheter har forekommet fra trekkspenninger som føres fra en påle til en annen under slagene. Disse spenninger, som f.eks. i betongpåler 0,2 5 The most significant difficulties have occurred from tensile stresses which are carried from one pile to another during the blows. These stresses, such as in concrete piles 0.2 5
x 0,2 5 m2 ofte overstiger.4 0 tonn, har man forsøkt å ta opp ved å bevirke i skjøten en tilsvarende forspenning, fordi den såkalte "klaring" eller forekomsten av mellomrom krever konstruksjonsholdbarhet og derved også vektøkning som igjen bevirker belastninger i betongkonstruksjonen ved frem-bringelsen av trykkbølgens refleksjonsfenomen for sekundær-spenninger. Forspenningen er frembragt ved konstruksjonens utformning i skjøtene under sammenføyningen (ABB- og A-skjøter), men kontrollen av.forspenningens grad har i praksis vært umulig. x 0.2 5 m2 often exceeds 4 0 tonnes, an attempt has been made to take up by causing a corresponding prestress in the joint, because the so-called "clearance" or the presence of spaces requires structural durability and thereby also an increase in weight which in turn causes stresses in the concrete construction by the production of the pressure wave reflection phenomenon for secondary voltages. The prestress is produced by the design of the construction in the joints during the joining (ABB and A joints), but control of the degree of the prestress has been impossible in practice.
Sammenføyningen ifølge oppfinnelsen er kjennetegnetThe joining according to the invention is characterized
ved at den egentlige skjøts sammenføyende skjøtedel stilles på plass og holdes der ved hjelp av et med gjenger forsynt ad-skilt sammenføynings- eller monteringselement. Således er det mulig å bestemme monteringselementets skruende kraft f.eks. in that the joining joint part of the actual joint is placed in place and held there by means of a separate jointing or assembly element provided with threads. Thus, it is possible to determine the mounting element's screwing force, e.g.
med en momentnøkkel og derved også forspenningen ved sammen-føyningens forlengelsesstenger. Et eget monteringselement gir. også mulighet for å forme de øvrige deler som hører til skjøtekonstruksjonen, på en hensiktsmessig måte, hvilket fremkommer som vektbesparelse av konstruksjonen. Da konstruksjonen kan dimensjoneres på en slik måte at den ved slaget fremkomne trekkbølgens oppstående maksimale spenninger holdes i låsedelene under materialets elastisitetsgrense tilsvarende den samrne bevirkede forspenning, kan "klaring" ikke opptre under slaget, hvilket igjen sikrer konstruksjonens dynamiske holdfasthet. with a torque wrench and thereby also the preload at the joint's extension rods. A separate mounting element provides. also the possibility of shaping the other parts that belong to the joint construction in an appropriate way, which appears as a weight saving of the construction. As the construction can be dimensioned in such a way that the maximum stresses arising from the tensile wave produced by the impact are kept in the locking parts below the material's elastic limit corresponding to the combined prestress, "clearance" cannot occur during the impact, which in turn ensures the dynamic holding strength of the construction.
Oppfinnelsen skal beskrives nærmere £ forbindelse med vedlagte tegninger, hvor fig. 1 viser sammenføyningsfordypningen i snitt,"hvor sammenføyningstappens åpning 10 og yegg-kons.truksjonen. 2,samt sammenføyningsskoen 1 er synlige. Fig. 2 er et planriss av sammenføyningsfordypningen sett ovenfra, hvor sammenføyningsstålets 4 g jengeforbindelse. i sammenføyningsfordypningens konstruksjon er synlig. Sammen-føyningsstålet kan også bindes sammen med konstruksjonen ved sveising. Fig. 3 viser sammenføyningsfordypningen i snitt, hvor sammenføyningstappens åpning 10 og sammen-føyningsstålets 4 sammenkobling, samt også fordypningen for monteringselementet som vist på fig. 9, fremgår. På fig. 4 er vist sammenføyningsfordypningen fra monteringselementets hull. Fig. 5 viser sammenføyningstappen ovenfra tilkoblets sammenføyningsskoen 1 og fig. 6 viser sammenføyningstappen i snitt, hvor koblingselementet som vist på fig. 8, eller koblingskilens åpning og sågar sammenføyningsstålets 4 sammenkobling med sammenføyningstappen er synlig. Fig. 7 viser ovennevnte konstruksjon i et snitt vinkelrett på den foregående. Fig. 10 viser sammenføyningskonstruksjonen bundet sammen til et funksjonerende element. Monteringselementet 9 er skrudd slik at det presser koblingskilen 5. Denne bevirker på sin side en løftende kraft over flaten 7 ti-1 sammenføyningstappen 3 og en nedover rettet kraft over flatene 8 til sammenføyningselementet 2, hvorved disse krefters innvirkning skaffer en forspenning ved sammen-føyningsskoenes felles flate 9.. Da strekkpåkjenningens -størrelse over sammenføyningsstålene 4 er mindre enn den frembragte forspenning, opptrer ikke den såkalte klaring, med andre ord forekommer det ikke bevegelse mellom sammen-fØyningsskoene. På fig. 11 er vist en mulig plassering av sammenføyningselementet i en sammenføyningssko 1 og på fig. The invention shall be described in more detail in connection with the attached drawings, where fig. 1 shows the joining recess in section, where the joining pin opening 10 and the yegg construction 2, as well as the joining shoe 1 are visible. Fig. 2 is a plan view of the joining recess seen from above, where the joining steel's 4 g male connection in the construction of the joining recess is visible. Together -the joining steel can also be joined to the construction by welding. Fig. 3 shows the joining recess in section, where the opening 10 of the joining pin and the connection of the joining steel 4, as well as the recess for the mounting element as shown in Fig. 9, can be seen. Fig. 4 shows the joining recess from the hole of the mounting element. Fig. 5 shows the joining pin from above connected to the joining shoe 1 and Fig. 6 shows the joining pin in section, where the connecting element as shown in Fig. 8, or the opening of the connecting wedge and even the connection of the joining steel 4 with the joining pin is visible. Fig. 7 shows the above construction in a section vi equal to the previous one. Fig. 10 shows the joining construction tied together into a functioning element. The mounting element 9 is screwed so that it presses the coupling wedge 5. This, in turn, causes a lifting force over the surface 7 of the joining pin 3 and a downwardly directed force over the surfaces 8 of the joining element 2, whereby the impact of these forces provides a pre-tension at the joining shoes joint surface 9.. Since the magnitude of the tensile stress over the joining steels 4 is less than the produced prestress, the so-called clearance does not occur, in other words, no movement occurs between the joining shoes. In fig. 11 shows a possible location of the joining element in a joining shoe 1 and in fig.
12 er vist en ferdig sammenføyning sett fra siden. 12 shows a finished joint seen from the side.
