Description
7903560-6 någon kraft av betydelse, som skulle klyva konstruktionen och utbryta åt sig tillräckligt djupa spår, i vilka kilbu1ua1sâsom tidigare känt sitter fast med kilstyckets hjälp. Kilstycket for- mas så, att dess tungor till först intränger i långsamt sluttan- de vinkel i borrhålets vägg och böjer sig sedan småningom i borr- hålets riktning, varvid materialet lossnar lätt från spåren. Kil- styckets slutdel kan utformas så, att dess tungor kan böja sig yt- terligare något tillbaka inåt, så att de mellan sig fastlåser kil- stycket och tillsammans bildar för kilbulten en ankardel av be- tydligt större vidd än borrhålets diameter. Plats på borrhålets botten för det av kilbulten från tungspåren lösgjorda materialet erhålles genom att förse kilstycket med en tillräckligt avsmalnad fot, som vilar mot borrhålets botten. Kilbulten kan vid behov för- ses med ytter- och innergängor och dess kluvna ände kan delas i hå eller flera mejselformade tungor. 7903560-6 any force of significance which would split the structure and break out sufficiently deep grooves, in which wedge bolts, as previously known, are fixed with the aid of the wedge piece. The wedge piece is shaped so that its tongues first penetrate at a slowly sloping angle into the borehole wall and then gradually bend in the direction of the borehole, whereby the material detaches easily from the grooves. The end part of the wedge piece can be designed so that its tongues can bend further back inwards, so that they lock the wedge piece between them and together form for the wedge bolt an anchor part of considerably greater width than the diameter of the borehole. Space on the bottom of the borehole for the material released by the wedge bolt from the tongue grooves is obtained by providing the wedge piece with a sufficiently tapered foot, which rests against the bottom of the borehole. The wedge bolt can, if necessary, be provided with outer and inner threads and its split end can be divided into hollow or several chisel-shaped tongues.
Ritningen visar ett exempel på en kilbult, som har fastsatts i ett borrhål med förfarandet enligt uppfinningen. I fig. 1 har kilbul- ten placerats i borrhålet före dess fastsättning genom slag och i fig. 2 ses kilbulten efter den uppfinningsenliga fastsättningen.The drawing shows an example of a wedge bolt which has been fixed in a borehole with the method according to the invention. In Fig. 1 the wedge bolt has been placed in the borehole before its fastening by stroke and in Fig. 2 the wedge bolt is seen after the fastening according to the invention.
Tungorna 2 i kilbultens kluvna ände har utformats som eggen på en mejsel, genom att böja deras spetsar något utåt och avfasa dem så, att vinkeln mot borrhålets vägg är spetsig. För att underlätta brytning av lösgörbart material från borrhålsväggen har bultens tungdel gjorts smalare på bägge sidor om bulten och tungornas bak- rekanter ännu smalare än framkanterna. Kilstycket har utformats så, att det vid kilbuüens fastsättning genom slag tvingar de mej- selformade tungorna 2 att intränga i borrhålets vägg i svagt lu- tande vinkel och böjer sig sedan efter kilstyckets 3 form i samma riktning som borrhålet och slutligen ytterligare tillbaka något in- åt, varvid kilstycket 3 låses fast mellan tungorna 2 så, att det icke ens kan lossna på grund av eventuell vibration. Samtidigt som tungorna 2 utbryter spår åt sig i borrhålets vägg, skjuter de framför sig materialet som de lösgjort från borrhålets vägg till borrhålets botten, där tillräckligt stort utrymme 4 reserverats bredvid kilstyckets 3 avsmalnade fot.The tongues 2 at the split end of the wedge bolt have been designed as the edge of a chisel, by bending their tips slightly outwards and chamfering them so that the angle to the wall of the borehole is acute. To facilitate breaking of detachable material from the borehole wall, the tongue part of the bolt has been made narrower on both sides of the bolt and the rear edges of the tongues even narrower than the front edges. The wedge piece has been designed so that when the wedge arch is fastened by impact, the chisel-shaped tongues 2 force to penetrate the wall of the borehole at a slightly inclined angle and then bend according to the shape of the wedge piece 3 in the same direction as the borehole. whereby the wedge piece 3 is locked between the tongues 2 so that it cannot even come loose due to possible vibration. At the same time as the tongues 2 break out grooves in the borehole wall, they push the material they have detached from the borehole wall to the bottom of the borehole, where sufficient space 4 is reserved next to the tapered foot of the wedge piece 3.
