DK 161851 BDK 161851 B

Den foreliggende opfindelse angår en forankring af en gevindstang ved hjælp af en compoundmasse i et borehul i en betondel.The present invention relates to anchoring a threaded rod by means of a compound mass in a borehole in a concrete part.

Til forankring af en gevindstang ved hjælp af en 5 kompoundmasse fremstilles først et borehul i det materiale, hvori forankringen skal foregå, og hvor diameteren er noget større end den udvendige diameter af gevindstangen. Dernæst indskubbes i borehullet en glasampul, der indeholder den af en polyesterharpiks, hærderen og tilslagsstoffer bestående 10 kompoundmasse. Med den i en boremaskine indspændte gevindstang knuses ampullen i borehullet og kompoundmassens komponenter aktiveres ved blanding. Efter afbinding af kompound-massen er gevindstangen fast indsat og forankret i borehul let. Forankringen beror i det væsentlige på en klæbeforbin-15 delse mellem kompoundmassen og borehullets væg. Den forbindelse bliver dog betydeligt mindre holdbar, når der forløber en revne gennem forankringsstedet. På grund af forstørrelsen af borehullet som følge af revnen løsner kompoundmassen sig fra borehullets væg, således at der kun foreligger små hol-20 dekræfter. På grund af denne omstændighed er forankringer i betonens trækzone, i hvilken der sædvanligvis findes revner, forbundet med en sikkerhedsrisiko.For anchoring a threaded rod by means of a compound compound, a borehole is first prepared in the material in which the anchorage is to be made and the diameter of which is somewhat larger than the outside diameter of the threaded rod. Next, a glass ampoule is inserted in the borehole containing the polyester resin, the hardener and additives comprising 10 compound mass. With the threaded rod inserted into a drill, the ampoule is crushed in the borehole and the components of the compound mass are activated by mixing. After bonding the compound mass, the threaded rod is firmly inserted and anchored in the borehole easily. The anchorage is essentially due to an adhesive connection between the compound mass and the borehole wall. However, this connection becomes significantly less durable as a crack passes through the anchorage site. Due to the enlargement of the borehole due to the crack, the compound mass loosens from the wall of the borehole so that only small hollow forces are available. Due to this circumstance, anchors in the concrete tensile zone in which cracks are usually found are associated with a safety risk.

Fra DE-A-3 325 800 kendes en forankring af en gevindstang i et borehul i en betondel ved hjælp af en 25 kompoundmasse, hvor borehullet er forsynet med en udvidelse i form af en underskæring. Gevindstangen har ved dens indføringsende et svingbart lejret vippeanker, som er indrettet til at svinges ud i en i tværsnit firkantet underskæring.From DE-A-3 325 800 an anchor of a threaded rod in a borehole in a concrete part is known by means of a compound compound, the borehole being provided with an extension in the form of an undercut. The threaded rod has at its insertion end a pivotally pitched rocker anchor which is arranged to be pivoted in a cross-sectional square cut.

Denne kendte forankring består af to dele og er dermed kost-30 bar at fremstille. Endvidere er fremstillingen af en sådan underskæring og indsættelsen af gevindstangen vanskelig.This known anchorage consists of two parts and is thus costly to manufacture. Furthermore, the preparation of such an undercut and the insertion of the threaded rod are difficult.

Endvidere kendes der fra DE-A-3 209 018 en forankring, ved hvilken der på indføringsenden af gevindstangen er udformet en konus, som er indrettet til at gribe ind i en 35 tilsvarende underskæring, hvor den kan sikres ved hjælp af en kompoundmasse, men denne forankring har imidlertid en spredebøsning, der på konventionel måde er skudt ned over gevindstangen, og som griber ind i underskæringen. Compound-Furthermore, from DE-A-3 209 018 an anchor is known in which a cone is arranged at the insertion end of the threaded rod adapted to engage a corresponding undercut where it can be secured by means of a compound mass, but however, this anchorage has a spreading bush, which is conventionally shot down over the threaded rod, which engages the undercut. Compound-

2 massen tjener herved til sikring af spredebøsningen på konussen, idet spredebøsningen ikke er ud i ét med gevindstangen.2 the mass thereby serves to secure the spreading bush on the cone, since the spreading bush is not integral with the threaded rod.

Den opgave, som ligger til grund for opfindelsen, er j 5 at muliggøre en forankring i trækzoner med en gevindstang og j kompoundmasse.The object of the invention is to enable anchoring in tensile zones with a threaded rod and compound compound.

I henhold til opfindelsen opnås dette ved, at en for- IAccording to the invention, this is achieved by providing a

ankring af den i indledningen til krav 1 angivne art er ejendommelig ved det i den kendetegnede del af krav 1 angiv-10 ne. Efter fremstilling af underskæringen i området ved borehullets bund med et til dette formål egnet bor gennemføres forankringen med den kendte fremgangsmåde. Gevindstangen drives så langt ind i borehullet, at konussen befinder sig i området ved underskæringen. Efter hærdningen danner den i ' 15 kompoundmassén indlejrede konus en på grund af sin form baseret fastlåsning. Når der optræder en revne gennem forankringsstedet, løsner kompoundmassén sig ganske vist fra borehullets væg, men så holdes nu gevindstangen fast ved sammenlåsningen i underskæringen, således at der trods revnedan-20 nelsen kan opnås høje hoIdeværdier. På grund af koniciteten i underskæringen bliver forøgelsen af borehullets størrelse udlignet ved en ringe udglidning. Også holdeværdierne i ikke revnet beton forbedres ved hjælp af løsningen ifølge opfindelsen, da der på grund af underskæringen og konussen på ge-25 vindstangen opstår en yderligere radial kraftkomponent.anchoring of the kind specified in the preamble of claim 1 is peculiar to that of the characterizing part of claim 1. After preparing the undercut in the area at the bottom of the borehole with a drill suitable for this purpose, the anchoring is carried out by the known method. The threaded rod is driven so far into the borehole that the cone is in the area at the undercut. After curing, the cone embedded in the '15 compound mass forms a latch due to its shape. When a crack occurs through the anchoring site, the compound mass is detached from the wall of the borehole, but the threaded rod is now held firmly by the interlock in the undercut, so that despite the crack formation, high head values can be obtained. Due to the conicity of the undercut, the increase in borehole size is offset by a slight slip. Also, the holding values in uncracked concrete are improved by the solution according to the invention, as a further radial force component is formed due to the undercut and cone on the threaded bar.

I henhold til en særlig udformning ifølge opfindelsen kan konusvinklen på gevindstangen svare til vinklen for underskæringen og den største konusdiameter omtrent svare til diameteren af borehullet. På grund af denne afstemning frem-30 kommer der også i området ved underskæringen en omslutning af gevindstangen med kompoundmasse af samme tykkelse som i det cylindriske skaftområde.According to a particular embodiment of the invention, the angle of the cone on the threaded rod may correspond to the angle of the undercut and the largest cone diameter approximately equal to the diameter of the borehole. Due to this tuning, an enclosure of the threaded rod with compound mass of the same thickness as in the cylindrical shaft region also appears in the area of the undercut.

I henhold til en komplettering ifølge opfindelsen kan gevindstangen umiddelbart foran konussen have et i diameter 35 reduceret afsnit. På grund af gevindstængerne transporteres kompoundmassén under blandingen i retning mod borehullets munding. Det i diameter reducerede, gevindløse afsnit virker som en transportspærring, således at underskæringen forbli-According to a supplement according to the invention, the threaded rod immediately in front of the cone may have a reduced diameter 35. Because of the threaded rods, the compound mass is transported during mixing in the direction of the borehole mouth. The diameter-reduced threadless section acts as a transport barrier, so that the undercut remains

3 ver fyldt med kompoundmasse også ved længere tids drejning af gevindstangen. For i dette område yderligere at sikre en forbindelse med gevindstangen kan det i diameter reducerede afsnit have omløbende riller.3 ver filled with compound mass also by prolonged rotation of the threaded rod. To further secure a connection with the threaded rod in this area, the diameter-reduced section may have circular grooves.

5 Endelig kan konussen på gevindstangen være forsynet med en ru overflade. På grund af denne ru overflade forbedres forbindelsen mellem konussen på gevindstangen og kompoundmassen.Finally, the cone on the threaded rod may be provided with a rough surface. Because of this rough surface, the connection between the cone of the threaded rod and the compound mass is improved.

I henhold til en særlig udformning ifølge opfindelsen 10 kan endefladen af konussen på gevindstangen være forsynet med i stjerneform forløbende kærve, der strækker sig frem til omkredsfladen af konussen. Ved hjælp af disse kærve opstår der skærekanter, der letter formalingen af glasampullen og blandingen af kompoundmassens komponenter. Endvidere op-15 står der på grund af kærvene gennembrydninger i området ved den største konusdiameter på gevindstangen, hvilket ved inddrivning af gevindstangen muliggør en opstigning af kompoundmassen over konussen i retning mod den cylindriske del af borehullet.According to a particular embodiment of the invention 10, the end surface of the cone of the threaded rod may be provided with a star-shaped groove extending to the circumferential surface of the cone. By means of these notches, cutting edges are formed which facilitate the grinding of the glass vial and the mixture of the components of the compound mass. Furthermore, due to the notches, breakthroughs occur in the region at the largest cone diameter of the threaded rod, which, by pushing the threaded rod, allows an increase of the compound mass over the cone towards the cylindrical part of the borehole.

20 Tegningen viser et udførelseseksempel på opfindelsen.The drawing shows an exemplary embodiment of the invention.

Forankringen af den med en konus 1 forsynede gevindstang 2 sker i et borehul 3, som i området ved borehullets bund er forsynet med en underskæring 4, der udvider sig i retning mod borehullets bund. Efter fremstilling af borehul-25 let anbringes en kompoundmasse 5 i borehullet 3 eksempelvis i form af en glasampul. Med en borehammer inddrives gevindstangen 2 i borehullet 3 og herved knuses glasampullen samtidig med, at kompoundmassens komponenter aktiveres ved blandingen. Gevindstangen er korrekt placeret, når konussen 30 1 på gevindstangen 2 befinder sig i området med underskærin gen 4. Dette kan eksempelvis være vist ved hjælp af en markering på gevindstangen. Det til konussen 1 tilsluttede, med omløbende riller 6 og i forhold til diameteren af gevindstangen 2 med reduceret diameter forsynede afsnit 7 danner 35 en transportspærring, således at underskæringen 4 forbliver fyldt med kompoundmasse også ved en for langvaring drejning af gevindstangen 2. Til forbedring af forbindelsen mellem konussen 1 på gevindstangen 2 og kompoundmassen 5 er konus-The anchoring of the threaded rod 2 provided with a cone 1 takes place in a borehole 3, which in the area at the bottom of the borehole is provided with a lower cut 4 which extends in the direction towards the bottom of the borehole. After preparation of the borehole, a compound mass 5 is placed in the borehole 3, for example in the form of a glass ampoule. With a drill hammer, the threaded rod 2 is driven into the borehole 3, thereby crushing the glass ampoule while activating the components of the compound mass during the mixing. The threaded rod is correctly positioned when the cone 30 1 of the threaded rod 2 is in the region of the undercut 4. This can be shown, for example, by means of a marking on the threaded rod. The cone 1 connected to the cone 1, with circular grooves 6 and in relation to the diameter of the reduced diameter threaded rod 2, 35 forms a transport barrier, so that the undercut 4 remains filled with compound mass even if the threaded rod 2 is too long rotated. the connection between the cone 1 of the threaded rod 2 and the compound mass 5 is the cone.
