t 3 2 145267t 3 2 145267
Fra beskrivelsen til U. S. A.-patent nr. 3.246.843 kendes en fastspændingsanordning, hvor det isolerende legeme er fastklæbet til oversiden af den bøjleformede metalliste, som er asymmetrisk i forhold til bolteaksen, hvilket bevirker en usymmetrisk fordeling af fastklemningskræfterne og en vis uligevægt af disse, som kan fremkalde skadelige materialespændinger i de sammenspændte dele.From the disclosure of U.S. Patent No. 3,246,843, a clamping device is known in which the insulating body is adhered to the upper surface of the sheathed metal strip which is asymmetrical with respect to the bolt axis, causing an asymmetrical distribution of the clamping forces and some unbalance thereof. which can cause harmful material stresses in the clamped parts.
Opfindelsen har til formål at afhjælpe disse ulemper, hvilket opnås ved de i kravets kendetegnende del angivne foranstaltninger.The invention aims to overcome these disadvantages, which is achieved by the measures specified in the characterizing part of the claim.
Herved vil de opståede lodrette trykkræfter overføres homogent og symmetrisk til svellens skulderfladeområde igennem dettes til den lodrette skulderflade grænsende øverste vandrette overflade og tilsammen med de vandrette trykkræfter danne imod svellens indre rettede resulterende kræfter, hvilket fjerner brudrisikoen i det forholdsvis sarte kantområde af svellen, ligesom trykkræfterne vil fordele sig symmetrisk på begge sider af bolten efter fastspændingen.Hereby, the resulting vertical compressive forces will be applied homogeneously and symmetrically to the swell's shoulder surface area through its upper horizontal surface adjacent to the vertical shoulder surface and together with the horizontal compressive forces will form against the swelling's internal directed resultant forces, thus removing the risk of fracture in the relatively delicate marginal area, will distribute symmetrically on both sides of the bolt after clamping.
Opfindelsen forklares nærmere nedenfor i forbindelse med tegningen, hvor: fig. 1 viser et lodret snit gennem en udførelsesform for et elastisk og isolerende fastspændingsorgan ifølge opfindelsen, anbragt på en betonsvelle, fig. 2 et tilsvarende organ, anvendt på en metalsvelle, og fig. 3 en anden udførelsesform for et fastspændingsorgan, anvendt på en betonsvelle.The invention is further explained below in connection with the drawing, in which: FIG. 1 shows a vertical section through an embodiment of an elastic and insulating clamping member according to the invention, arranged on a concrete slab; FIG. 2 shows a similar means applied to a metal sleeve; and FIG. 3 shows another embodiment of a clamping member applied to a concrete slab.
1 fig. 1 ses en betonsvelle 1, på hvilken der hviler en skinnefod 2 på en isolationsplade 3.1 FIG. 1 shows a concrete slab 1 on which a rail foot 2 rests on an insulation plate 3.
I den støbte svelle 1 findes et hul 4 til passage for en bolt 5 med et som en hammer formet hoved 6, der på kendt måde er fastholdt i en holdeplade 7. 1 svellen 1 findes udstøbt en anlægsflade 8, der er dannet af et bryst i den øverste del af hullet 4, og som danner en toplansvinkel, hvis kant er parallel med skinnen.In the molded sleeper 1, a hole 4 is provided for passage of a bolt 5 with a hammer-shaped head 6, which is in a known manner retained in a holding plate 7. 1 the sleeve 1 is found cast a abutment surface 8 formed by a chest in the upper portion of the hole 4, forming a top plane angle whose edge is parallel to the rail.

Mellem syellens anlægsflade 8 og en lodret kant 9 på skinnefoden 2 er anbragt en spændeklods 10, fremstillet ved støbning eller presning af en plast eller syntetisk harpiks med passende isolerende egenskaber, eller på basis af en vulkaniseret elastomer eller andet materiale, der har den fornødne mekaniske styrke.Between the abutment surface 8 of the sleeve and a vertical edge 9 on the rail foot 2 is arranged a clamping block 10, made by molding or pressing a plastic or synthetic resin with suitable insulating properties, or on the basis of a vulcanized elastomer or other material having the necessary mechanical strength.
Spændeklodsen 10 har omtrent form som et parallelepipedum, som har et omtrent centralt hul 11.The clamping block 10 has approximately the shape of a parallelepipedum which has an approximately central hole 11.
Spændeklodsen 10 har to i ét med den fremstillede vinger 12 og 13» der rager ud fra klodsens øverste del til hver side af denne.The clamping block 10 has two in one with the manufactured wings 12 and 13 extending from the upper part of the block to each side thereof.
Yderenderne af vingerne 12 og 13 har en opstående kant 14, og deres overflade er fortrinsvis svagt konkav med frembringers parallelle med skinnen.The outer ends of the wings 12 and 13 have an upright edge 14, and their surface is preferably slightly concave with generators parallel to the rail.
Den ene sideflade 15 på klodsen 10 ligger an mod anlægsfladen 8 i svellen 1, medens den anden sideflade 16 ligger an mod skinnefoden 2*s kant 9. Yingerne 12 og 13 strækker sig henholdsvis mod skinnefoden 2 og svellens overflade ved anlægsfladen 8.One side surface 15 of the block 10 abuts the abutment surface 8 of the sleeper 1, while the other side surface 16 abuts the edge of the rail foot 2 *. The gutters 12 and 13 extend respectively towards the rail base 2 and the surface of the swell at the abutment surface 8.
På vingerne 12 og 13 er mellem kanterne 14 anbragt en metalplade 17» fortrinsvis af fjederstål, med et centralt hul 18.On the wings 12 and 13 is arranged between the edges 14 a metal plate 17 »preferably of spring steel, with a central hole 18.
Bolten 5 går gennem klodsen 10, hullet 18 i pladen 17 og bærer en møtrik 19.The bolt 5 passes through the bracket 10, the hole 18 in the plate 17 and carries a nut 19.
Når møtrikken 19 spændes til, bøjes pladen 17 nedefter, svarende til formen af vingerne 12 og 13's konkave overflade, hvorved skinnefoden 2 spændes mod svellen 1 og med sin kant 9 holdt til anlæg med sidefladen 16 på klodsen 10.As the nut 19 is tightened, the plate 17 bends downward, corresponding to the shape of the concave surface of the wings 12 and 13, whereby the rail foot 2 is tensioned against the sleeper 1 and with its edge 9 held to abut with the side surface 16 of the bracket 10.
længden af klodsen 10, målt parallelt med skinnefodens kant - og skinnelegemets længdeakse -, svarer omtrent til den tilsvarende dimension af anlægsfladen 8 og vælges tilstrækkelig stor, f.eks.the length of the block 10, measured parallel to the edge of the rail foot - and the longitudinal axis of the rail body - corresponds approximately to the corresponding dimension of the abutment surface 8 and is chosen sufficiently large, e.g.
80 mm, til at de tryk, der udøves af sidefladerne 15 og 16, ved virkningen af på skinnen virkende tværkræfter, særligt i kurver, ikke overskrider de arbejdsudsving ved kompression, som det valgte isolationsmateriale kan tåle uden at flyde ud.80 mm, so that the pressure exerted by the side surfaces 15 and 16, by the action of transverse forces acting on the rail, especially in curves, does not exceed the working fluctuations by compression which the chosen insulating material can withstand without flowing out.

Ved den i forbindelse med en typisk metalsvelle i fig. 2 viste udførelsesform hviler spændeklodsen 10 indirekte på svellen 21 ved hjælp af et mellemstykke 22, der tjener til at danne en anlægsflade 28 for en sideflade 25 på klodsen.In connection with the typical metal swell of FIG. 2, the clamping block 10 rests indirectly on the sleeper 21 by means of an intermediate piece 22 which serves to form a abutment surface 28 for a side surface 25 of the block.
Mellemstykket 22 er f.eks. af metal og bærer et fremspring 23» som rager ned gennem et hul 24 i svellen, og stykkets anlægsflade 28 er omtrent vinkelret på svellen og ligger parallelt med skinnen og danner anlæg for sidefladen 25 af spændeklodsen 10.The intermediate piece 22 is e.g. of metal and carries a projection 23 »which projects down through a hole 24 in the sleep, and the abutment surface 28 of the piece is approximately perpendicular to the sleep and lies parallel to the rail and forms abutment for the side surface 25 of the clamping block 10.
længden af sidefladen 25 og anlægsfladen 28, målt parallelt med skinnelegemets akse, er valgt tilstrækkelig stor til, at sammentrykningerne af det syntetiske materiale klodsen er fremstillet af, ligger inden for dets elasticitetsområde og under de værdier, der kan medføre blivende formforandringer ved udflydning med tryk. Afstanden mellem skinnefodens kant og anlægsfladen 28 er valgt således, at der på tværs af skinnen opretholdes en passende elasticitet som funktion af isolationsmaterialets elasticitetsmodul i klodsen.the length of the side surface 25 and the abutment surface 28, measured parallel to the axis of the rail body, is chosen sufficiently large that the compressions of the synthetic material are made of the block are within its range of elasticity and below the values which can cause permanent shape changes upon flow with pressure . The distance between the edge of the rail foot and the abutment surface 28 is chosen such that a suitable elasticity is maintained across the rail as a function of the modulus of elasticity of the insulating material in the block.
Skinnens lodrette stilling på svellen er sikret elastisk med bolten 5 - vist utilspændt i fig. 2 -, hvis møtrik ligger an mod * f jederstålpladen 17. Den korrekte tilspænding er let at konstatere, hvis man har givet pladen 17 et sådant udgangsprofil over oversiden af vingerne, mod hvilke den lægger sig an, at der mellem pladen og klodsen fremkommer et spillerum J midt mellem pladens anlægspunkter. Dette spillerum J, i det i fig. 2 viste tilfælde, fremkommer på grund af vingeoversidens konkave form, og denne krumning er beregnet således, ligesom spillerummet J> at pladen i hele sin længde lægger sig an mod klodsen, og spillerummet J forsvinder, når bolten spændes til, og den tilsvarende lodrette kraft, der overføres til skinnefoden, har nået den krævede værdi.The vertical position of the rail on the sleepers is secured elastically with the bolt 5 - shown unfastened in fig. 2 - if the nut abuts against the spring steel plate 17. The correct tightening is easy to ascertain if the plate 17 has such an output profile over the top of the wings against which it assumes that a plate is formed between the plate and the bracket. clearance J in the middle of the plate's contact points. This clearance J, in the embodiment shown in FIG. 2, due to the concave shape of the wing surface, and this curvature is calculated, as is the clearance space J> that the plate is in full length against the block and the clearance J disappears when the bolt is tightened and the corresponding vertical force that is transferred to the rail foot has reached the required value.
Den fjedrende plade 17 har tre funktioner.The resilient plate 17 has three functions.
Den giver på i og for sig kendt måde fastgørelsen den ønskede elasticitet i lodret retning samtidigt med, at spillerummet J, der be- 5 1Λ5267 stemmer den reelle spændekraft for bolten på samme måde som et dynamometer kan reguleres.It provides, in a manner known per se, the desired elasticity in the vertical direction, at the same time that the clearance J, which determines the real tension of the bolt in the same way as a dynamometer can be controlled.
Den fordeler spsendekraften fra bolten på vingerne 12 og 13 ved hjælp af klodsens store isolerende flader, og de tryk, der virker på vingerne, kan således begrænses til en antagelig værdi, som ikke medfører udflydning ved sammentrykning.It distributes the clamping force of the bolt to the blades 12 and 13 by means of the large insulating surfaces of the block, and the pressures acting on the blades can thus be limited to an acceptable value which does not result in flow by compression.
Den beskytter den del af klodsen, der ligger mellem kanten af skinnefoden og anslagsfladen på mellemstykket, idet pladen 17 danner en bro mellem anlægsstederne på skinnen og mellemstykket 22, medens spillerummet J bevirker, at enhver risiko for en sammenspænding, der medfører blivende formforandring på pladen 17 så vel som på den isolerende klods, er udelukket.It protects the part of the bracket which lies between the edge of the rail foot and the abutment surface of the spacer, the plate 17 forming a bridge between the abutment points of the rail and the spacer 22, while the clearance space J causes any risk of a collision causing permanent shape change on the plate. 17 as well as on the insulating globe, are excluded.
Pig. 3 viser en udførelsesform til anvendelse på en betonsvelle 31 af kendt art, som ved fremstillingen er forsynet med en indefter buet anlægsflade 38 til optagelse af en vulst på en metal-spændeklods af kendt art.Pig. 3 shows an embodiment for use on a concrete slab 31 of known kind, which in the manufacture is provided with an inwardly curved abutment surface 38 for receiving a bead on a metal clamping block of known kind.
I dette tilfælde har klodsen 10 i ét med den og med en tykkere vinge 13 en afrundet knast 33 med en flade 35, hvis form svarer til formen af anlægsfladen 38 på svellen.In this case, the bracket 10 has one at a time with it and with a thicker wing 13 a rounded cam 33 with a surface 35, the shape of which corresponds to the shape of the abutment surface 38 of the sleeper.
