Description
Oppfinnelsen vedrører en ankerbolt for forankring i en boring, med en spennbolt som har et gjengeparti og et derfra konusformet utvidet hodeparti og med en hylse med et innvendig gjengeparti og et tilgrensende, sektorformet utspilbart forankringsparti. The invention relates to an anchor bolt for anchoring in a borehole, with a tension bolt that has a threaded part and a cone-shaped extended head part from there and with a sleeve with an internal threaded part and an adjacent sector-shaped extendable anchoring part.
Slike ankerbolter er kjent. De har en hylse hvis forankringsparti danner en hul sylinder forsynt med akseparallelle slis-ser og med sirkulært tverrsnitt. Spennboltens gjengeparti blir fra forankringspartiets side skrudd inn i hylsens innvendige gjenger og de to deler innføres i en boring som en enhet. Der-etter dreies spennbolten ytterligere inntil den med sitt konusformede hodeparti spiler ut hylsens utspilbare forankringsparti og dermed forankrer hylsen i det omgivende materiale, Such anchor bolts are known. They have a sleeve whose anchoring part forms a hollow cylinder provided with axis-parallel slots and with a circular cross-section. The threaded part of the tension bolt is screwed from the side of the anchoring part into the internal threads of the sleeve and the two parts are inserted into a bore as a unit. The tension bolt is then turned further until, with its cone-shaped head part, it plays out the sleeve's extendable anchoring part and thus anchors the sleeve in the surrounding material,
som tre, sponplate eller betong. such as wood, chipboard or concrete.
Ulempen ved nevnte, konvensjonelle ankerbolt er at det er fare for at hylsen dreier med i boringen når spennbolten trekkes til, slik at hylsen ikke kan spiles ut og dermed ikke blir forankret. The disadvantage of the aforementioned, conventional anchor bolt is that there is a danger that the sleeve rotates with the bore when the tension bolt is tightened, so that the sleeve cannot be spread out and thus is not anchored.
Det er gjort forsøk på å forsyne hylsens overflate med en rif-ling, men selv dette har ikke alltid ført til ønsket resultat Forøvrig har en hylse med sirkulært tverrsnitt den ulempe at Attempts have been made to provide the surface of the sleeve with a knurling, but even this has not always led to the desired result. Otherwise, a sleeve with a circular cross-section has the disadvantage that
de utspilte, sirkelbueformede segmenter bare i liten grad har skarpe hjørner og kanter for forankring i materialet. the flared, circular arc-shaped segments have only a small amount of sharp corners and edges for anchoring in the material.
Fra DE-PS 65 940 er det kjent en befestigelsesbolt hvor det ved dennes fremre ende er anordnet et i retning forover utvidet, konisk parti som omgis av et antall langstrakte plater som ved sin bakre ende holdes sammen av en trådring. Ved tiltrekning av bolten ved hjelp av en mutter, forskyver bolten seg bakover slik at platene ved sin fremre ende blir skjøvet fra hverandre av det koniske parti og derved forankret i boringen. Totalt sett oppviser platene et stort sett polygonalt omriss. From DE-PS 65 940, a fastening bolt is known where at its front end there is arranged a forwardly extended, conical part which is surrounded by a number of elongated plates which are held together at their rear end by a wire ring. When the bolt is tightened by means of a nut, the bolt moves backwards so that the plates at its front end are pushed apart by the conical part and thereby anchored in the bore. Overall, the plates show a largely polygonal outline.
Denne løsning er ugunstig bl.a. fordi det er nødvendig å montere fem eller flere plater rundt bolten og holde disse sammen ved hjelp av en tråd. Denne tidkrevende fremstillingsmetode fører til relativt store fremstillingsomkostninger. Dertil er det fare for at de enkelte plater kan løsne fra bolten ved lagring og transport. En ytterligere ulempe består i at platene skyves fra hverandre ved boltens fremre ende, slik at de riktignok klemmes fast i boringen, men ikke forankres tilstrekkelig mot uttrekning. This solution is unfavorable i.a. because it is necessary to fit five or more plates around the bolt and hold them together with a thread. This time-consuming manufacturing method leads to relatively large manufacturing costs. In addition, there is a risk that the individual plates may loosen from the bolt during storage and transport. A further disadvantage is that the plates are pushed apart at the front end of the bolt, so that they are indeed clamped firmly in the bore, but are not anchored sufficiently against extraction.
Til grunn for oppfinnelsen ligger derfor den oppgave å utforme en ankerbolt som angitt i hovedkravets innledning, på en slik måte at den tillater momentan, sikker og varig forankring i materialet. The basis of the invention is therefore the task of designing an anchor bolt as stated in the introduction of the main claim, in such a way that it allows momentary, safe and permanent anchoring in the material.
Denne oppgave løses ved en ankerbolt av den innledningsvis nevnte type ved at hylsen har polygonalt tverrsnitt og i midtområdet av polygonets sider er forsynt med akseparallelle, forhåndssvekkede utspilingslinjer. This task is solved by an anchor bolt of the type mentioned at the outset in that the sleeve has a polygonal cross-section and in the central area of the sides of the polygon is provided with axis-parallel, pre-weakened expansion lines.
Hylsens polygonale, især sekskantede tverrsnitt hindrer effek-tivt enhver meddreining av hylsen når spennbolten trekkes til. Som følge av den polygonale tverrsnittsform oppnås dessuten på den utspilbare side av hylsen et antall ekstra, skarpe kanter The sleeve's polygonal, especially hexagonal cross-section effectively prevents any rotation of the sleeve when the tension bolt is tightened. As a result of the polygonal cross-sectional shape, a number of additional, sharp edges are also obtained on the unfoldable side of the sleeve
i in
som letter inntrengning i materialet og fastlåsing der. which facilitates penetration into the material and locking there.
Ved en foretrukken utførelsesform har hylsen i det utspilbare forankringsparti, med utgangspunkt i det gjengede parti, en konusformet utvidelse som samvirker med det konusformede hodeparti av spennbolten. Begge konusflater tilsammen muliggjør en myk, jevn utspiling av hylsen ved lite oppbud av krefter, slik at også dette reduserer faren for at hylsen ved dreining av spennbolten dreies med eller trekkes ut før forankring kan finne sted. In a preferred embodiment, the sleeve in the extendable anchoring part, starting from the threaded part, has a cone-shaped extension which cooperates with the cone-shaped head part of the tension bolt. Both cone surfaces together enable a soft, even expansion of the sleeve with little build-up of forces, so that this also reduces the risk of the sleeve being turned with or pulled out when the tension bolt is turned before anchoring can take place.
I de akseparallelle midtlinjer i polygonets flater er det for-trinnsvis anordnet spor, som kan ha V-formet tverrsnitt. Det er hensiktsmessig at spordybden og forløpet av den konusformede utvidelse i det indre av hylsens forankringsparti avstemmes slik til hverandre at begge i det vesentlige faller sammen i hylsens frie kant, slik at en momentan opprivning og spred-ning av hylsen er mulig der. In the axis-parallel center lines in the faces of the polygon, grooves are preferably arranged, which may have a V-shaped cross-section. It is appropriate that the groove depth and the course of the cone-shaped expansion in the interior of the sleeve's anchoring part are matched to each other in such a way that both essentially coincide in the sleeve's free edge, so that a momentary tearing and spreading of the sleeve is possible there.
Spennbolten, som er i og for seg kjent, kan være utformet slik at det konusformede utvidede hodeparti danner en glatt, sylindrisk spindel, i hvis ende det er anordnet en utvidelse i form av et sliss-skrue- eller innvendig 1sekskant-skruehode. The tension bolt, which is known per se, can be designed so that the cone-shaped extended head portion forms a smooth, cylindrical spindle, at the end of which an extension in the form of a slotted screw or internal 1-hexagon screw head is arranged.
Ytterligere detaljer ved oppfinnelsen vil fremgå av underkrave-ne. Further details of the invention will appear from the sub-claims.
I det folgende skal noen foretrukne utforelseseksempler av oppfinnelsen beskrives under henvisning til tegningen, hvor In the following, some preferred embodiments of the invention will be described with reference to the drawing, where
fig. 1 viser et partielt snitt av en anordning bestående av spennbolt og hylse for montering, fig. 1 shows a partial section of a device consisting of a tension bolt and sleeve for mounting,
fig. 2 er et oppriss i stbrre målestokk av hylsen, sett etter linjen 2-2 i fig. 1, fig. 2 is an elevation on a larger scale of the sleeve, seen along the line 2-2 in fig. 1,
fig. 3 er et partielt snitt av ankerbolten under tiltrekking, fig. 3 is a partial section of the anchor bolt under tightening,
fig. 4 er et snitt etter linjen 4-4 i fig. 3. fig. 4 is a section along the line 4-4 in fig. 3.
I fig. 1 er en hylse betegnet med 10 og en spennbolt med 12. Hylsen består i lengderetning av to partier, som i fig. 1 er betegnet med 14 til venstre, et parti med innvendig gjenging, og med 16 til hoyre, et utspilbart forankringsparti. Det innvendig gjengede parti 14 har en konsentrisk, aksial boring 18 med innvendig gjenging. Forankringspartiet 16 har en innvendig boring 20, som er konusformet utvidet mot den frie enden (mot hoyre i fig. 1). Boringens 20 konusvinkel er forholdsvis liten og kan f.eks. være 3-4° med henblikk på hylsens sentrale akse. Som vist i fig. 2, har hylsen 10 sekskantet tverrsnitt. In fig. 1, a sleeve is denoted by 10 and a tension bolt by 12. The sleeve consists in the longitudinal direction of two parts, as in fig. 1 is denoted by 14 on the left, a part with internal threading, and by 16 on the right, an extendable anchoring part. The internally threaded part 14 has a concentric, axial bore 18 with internal threading. The anchoring part 16 has an internal bore 20, which is cone-shaped and extended towards the free end (towards the right in Fig. 1). The bore's 20 cone angle is relatively small and can e.g. be 3-4° with respect to the sleeve's central axis. As shown in fig. 2, the sleeve 10 has a hexagonal cross-section.
I de langsgående midtlinjer av de seks flater som begrenser hylsen utad er det anordnet spor 22, som f.eks. kan ha V-formet tverrsnitt. In the longitudinal center lines of the six surfaces which limit the sleeve outwards, there is arranged groove 22, which e.g. may have a V-shaped cross-section.
Boringens 20 utvidelse og dybden av sporene 22 er avstemt slik på hverandre, at de i det vesentlige faller sammen, eller eventuelt er atskilt med en meget liten materialtykkelse som uten videre kan brytes i hoyre ende av hylsen, som vist i fig. 1. The expansion of the bore 20 and the depth of the grooves 22 are matched to each other in such a way that they essentially coincide, or are possibly separated by a very small thickness of material which can easily be broken at the right end of the sleeve, as shown in fig. 1.
Spennbolten som er vist til hoyre i fig. 1, har et gjengeparti 24 som er forsynt med utvendige gjenger, og et tilgrensende, avskåret konusformet hodeparti 26. Gjengepartiets 24 utvendige gjenger svarer til de innvendige gjenger i boringen 18. Det avskåret konusformede hodeparti 26 må ikke nodvendigvis ha en noyaktig konusflate, men kan også være skrådd eller avrundet på annen måte. Hodepartiet 26 går i det viste eksempel over i en sylindrisk spindel 28 med valgfri lengde og et tilgrensende hode 30 for inngrep med en skrutrekker eller en sekskantnokkel. I stedet for spindelen og hodet 30 kan det dog være anordnet andre elementer, som tillater dreining og avstotting av spennbolten 12 mot venstre i fig. 1. The tension bolt shown on the right in fig. 1, has a threaded portion 24 which is provided with external threads, and an adjacent, cut-off cone-shaped head portion 26. The external threads of the threaded portion 24 correspond to the internal threads in the bore 18. The cut-off conical head portion 26 does not necessarily have to have a precise conical surface, but can also be beveled or rounded in another way. In the example shown, the head portion 26 transitions into a cylindrical spindle 28 of any length and an adjacent head 30 for engagement with a screwdriver or a hex key. Instead of the spindle and head 30, however, other elements can be arranged, which allow turning and pushing back of the tension bolt 12 to the left in fig. 1.
Ved montering av ankerbolten ifolge oppfinnelsen fores forst det gjengede parti 24 gjennom forankringspartiet 16 og skrus inn i boringen 18, inntil det konusformede hodeparti 12 f.eks. hviler lost mot hoyre ende av hylsen. I denne stilling innfores hylsen og spennbolten som enhet i en boring. Det kan f.eks. dreie seg om en boring i en betongvegg eller i konstruksjons-deler av tre eller sponplate. Kasseformede mbbler kan f.eks. monteres idet det til enhver tid i en plate bores blindhull fra kantene, mens i rett vinkel tilgrensende plater forsynes med boringer med en forsenkning for hodet 30. Disse monteringsmu-ligheter er i og for seg kjent og derfor ikke nærmere vist. When installing the anchor bolt according to the invention, the threaded part 24 is first fed through the anchoring part 16 and screwed into the bore 18, until the cone-shaped head part 12 e.g. rests loosely against the right end of the sleeve. In this position, the sleeve and the tension bolt are inserted as a unit in a bore. It can e.g. involve a bore in a concrete wall or in construction parts made of wood or chipboard. Box-shaped mbblers can e.g. is mounted by drilling blind holes from the edges at any time in a plate, while at right angles adjacent plates are provided with holes with a recess for the head 30. These mounting options are known in and of themselves and are therefore not shown in more detail.
Enheten av hylsen 10 og spennbolten 12 innfores i boringen, inntil hodet 30 er i anlegg mot et egnet anslag, f.eks. bunnen i en blindboring. Når spennbolten 12 i denne stilling dreies videre, vil hylsen 10 på grunn av gjengeinngrepet mellom det gjengede parti 24 og boringen 18 bli trukket til og samtidig utspilt, som vist i fig. 3. Ved denne utspiling vil forankringspartiet 16 rives opp i området for sporene 22 (fig. 2) og danne enkelte segmenter 32 (fig. 2). Disse segmentene trenger pro-gressivt inn i materialet i tilgrensende boringsvegg, slik at hylsen forankres i boringen. Derved fremkommer i det vesentlige den stilling som er vist i fig. 4. The unit of the sleeve 10 and the tension bolt 12 is inserted into the bore, until the head 30 is in contact with a suitable abutment, e.g. the bottom of a blind borehole. When the tension bolt 12 in this position is turned further, the sleeve 10 will, due to the threaded engagement between the threaded part 24 and the bore 18, be pulled to and at the same time expanded, as shown in fig. 3. During this expansion, the anchoring part 16 will be torn up in the area of the grooves 22 (fig. 2) and form individual segments 32 (fig. 2). These segments progressively penetrate the material in the adjacent borehole wall, so that the sleeve is anchored in the borehole. Thereby essentially the position shown in fig. 4.
Hylsens 10 tverrsnittsform ifolge oppfinnelsen har ikke bare den fordel at meddreining av hylsen under tiltrekkingen ute-lukkes. Av fig. 4 fremgår at de enkelte segmenter 32 danner et stbrre antall skarpe kanter enn det f.eks. er tilfelle ved sylindriske, utspilbare hylser. Disse skarpe kantene letter inn-trengningen i materialet i boringens vegg og dermed hylsens forankring. The cross-sectional shape of the sleeve 10 according to the invention not only has the advantage that rotation of the sleeve during tightening is excluded. From fig. 4 it appears that the individual segments 32 form a greater number of sharp edges than e.g. is the case with cylindrical, expandable sleeves. These sharp edges facilitate the penetration of the material into the wall of the bore and thus the anchoring of the sleeve.
Ankerbolten ifolge oppfinnelsen muliggjor f.eks. en hjornefor- The anchor bolt according to the invention enables e.g. a corner for-

Etter forankring sitter hylsen 10 fast i tilhorende boring. Den vil fortsatt sitte fast i boringen, hvis spennbolten 12 skrus ut og eventuelt skrus inn igjen senere. After anchoring, the sleeve 10 is fixed in the corresponding bore. It will still be stuck in the bore, if the tension bolt 12 is unscrewed and possibly screwed back in later.
