Den foreliggende opfindelse angår et forankringssæt fortrinsvis til forankring i betonbygningsdele og bestående af en sprededyvel og en befæstigelsesskrue, idet sprededyvlen er af formstof og til inddrejning og udspænding af befæstigelsesskruen har en langsgående glat' boring eller spalte.The present invention relates to an anchoring set preferably for anchoring in concrete building parts and consisting of a spreading devil and a fastening screw, the spreading devil being of plastic and for turning and tightening the fastening screw having a longitudinal smooth bore or gap.
Forankringen af sprededyvler af formstof sker i almindelighed ved inddrejning af træskruer, der som bekendt er forsynet med et gevind med skarp profil. Ved inddrej-ningen trænger gevindprofilets skarpe kant dybt ind i dyvelmaterialet, hvilket medfører en svækkelse af dyvlens tværsnit. Denne svækkelse er normalt af mindre betydning, fordi dyvlens godstykkelse er væsentligt større end gevinddybden. I øvrigt er spredevirkningen i almindelighed baseret på, at dyvlens boring er mindre end skruens kernediameter, således at spredevirkningen først og fremmest skyldes en udspiling på grund af indkiling af skruens kerne i dyvlens opslidsning eller boring. Et eksempel på en sådan udspredning af dyvler er beskrevet i fransk patentskrift nr 2.310.490.The anchoring of plastic spreading devils is generally done by turning in wood screws which, as is well known, are provided with a sharp profile thread. Upon recess, the sharp edge of the threaded profile penetrates deep into the dowel material, causing a weakening of the dowel cross section. This weakening is usually of minor importance because the thickness of the dowel is substantially greater than the thread depth. Moreover, the spreading effect is generally based on the fact that the bore of the devil is smaller than the core diameter of the screw, so that the spreading effect is primarily due to a flushing due to the insertion of the core of the screw into the slit slit or bore. An example of such a spread of dowels is described in French Patent Specification No. 2,310,490.
Der kendes andre gevindformer end det skarpe træ-skruegevind. Fra britisk patentskrift nr 733.587 kendes skruer med rundgevind indrettet til fastgørelse i trædyvler. Disse skruer indsættes i borehuller, der i forvejen er forsynet med et indvendigt gevind, og formålet med fremgangsmåden er at forhindre, at træet i dyvlerne splin-tres, idet træets langsgående fibre overskæres, hvilket ville resultere i en reduktion af holdeværdien.Threads other than the sharp wood screw thread are known. From British Patent Specification No. 733,587 are known screws with round thread arranged for fastening in wood devils. These screws are inserted into bore holes already provided with an internal thread, and the purpose of the method is to prevent the wood in the dowels from being shattered, cutting the longitudinal fibers of the wood, which would result in a reduction in retaining value.
Formålet med den foreliggende opfindelse er at tilvejebringe et forankringssæt, der er egnet til gennemstiks-montage, dvs., at dyvlen kun er ubetydeligt større end skruens største diameter, på en sådan måde, at der både i hårde og mindre hårde materialer opnås gode holdeværdier.The object of the present invention is to provide an anchoring set suitable for piercing mounting, i.e., that the die is only slightly larger than the largest diameter of the screw, in such a way that good holding values are obtained in both hard and less hard materials. .
Der tilstræbes altså den egenskab ved forankringssættet, at der ved hårde materialer, der kan tåle et stort spre-detryk, opnås et kraftigt tryk mod borehulsvæggen, medens der i blødere materialer opnås en større udspredning, men 148666 2 et· mindre tryk mod borehulsvæggen.Thus, the aim of the anchoring set is to be that, for hard materials that can withstand a large spread pressure, a strong pressure is obtained against the borehole wall, while in softer materials a larger spread is obtained, but a smaller pressure against the borehole wall.
Ifølge opfindelsen opnås dette ved, at befæstigel-sesskruen, hvis kernediameter tilnærmelsesvis er den samme som den indvendige diameter af sprededyvlens langsgående boring, har rundgevind samt en med et tilspidset gevindudløb forsynet skruespids, idet sprededyvlens spalte er udformet som mod enderne begrænset indslidsninger, langs Hvilke der er placeret en liste, hvis længde svarer til indslidsningerne.According to the invention, this is achieved by having the fastening screw, the core diameter of which is approximately the same as the inside diameter of the longitudinal bore of the spreading drill, has a round thread and a screwed point with a tapered thread outlet, the spreader of the spreading cutter being formed as ends along the ends. a list is placed whose length corresponds to the incisions.
Det tilspidsede gevindudløb ved skruespidsen bevirker, at skruen umiddelbart lader sig indsætte, og at udspilingen af dyvlen kan påbegyndes, idet listerne forhindrer en meddrejning af dyvlen. På grund af gevindformen fordres der et meget stort tryk til at deformere dyvlens formstof omkring gevindets kant. Kun hårde materialer i borehulsvæggen vil være i stand hertil, og i disse tilfælde vil dyvelmaterialet presses sammen i gevindets fordybninger under et meget stort tryk. Mindre hårde materialer vil ikke kunne holde til et sådant tryk, og dyvlen vil derfor under en mindre deformation henover gevindets kant blive udspilet tilsvarende og derved sikre en god fastkiling i materialet. Forankringssættet giver således en så at sige automatisk tilpasning til det materiale, hvori borehullet er fremstillet, og yder derfor stor modstand mod udtrækning under alle forhold.The tapered thread outlet at the screw tip causes the screw to be inserted immediately and playback of the dowel can be started, the moldings preventing the rotation of the dowel. Due to the thread shape, a very large pressure is required to deform the fabric of the devil around the edge of the thread. Only hard materials in the borehole wall will be capable of this, and in these cases the dowel material will be compressed in the recesses of the thread under a very high pressure. Less hard materials will not be able to withstand such pressure, and therefore, during a minor deformation over the edge of the thread, the die will be played out accordingly, thus ensuring a good wedge wedge in the material. Thus, the anchoring set provides an almost automatic adaptation to the material in which the borehole is made, and therefore provides great resistance to extraction under all conditions.
Endvidere kan i henhold til en komplettering i-følge opfindelsen den udvendige diameter af sprededyvlen tilnærmelsesvis svare til den udvendige diameter af gevindet. Den samme udvendige diameter af dyvlen og befæ-stigelsesskruen muliggør anvendelsen af et gennemgående med samme diameter forsynet borehul i genstanden, som skal befæstiges, og i murværket, hvilken boring lader sig gennemføre i en enkelt arbejdsgang. Befæstigelsesskruen ligger herved umiddelbart an mod væggen af genstanden, som skal fastgøres, og ved en dybere indsat dyvel også an mod væggen af borehulsmundingen i murværket, således at bøjningspåvirkninger i videst muligt omfang udelukkes. Ved denne udformning fremkommer der desuden en særdeles stærk 148666 3 udspænding og fastkiling af dyvelmaterialet i gevindgængerne, således at der endog kan opnås usædvanligt høje holdekræfter.Furthermore, according to a supplement according to the invention, the outside diameter of the spreading devil can approximately correspond to the outside diameter of the thread. The same outside diameter of the dowel and the mounting screw allow the use of a through-diameter borehole in the article to be fastened and in the masonry, which bore can be completed in a single operation. The fastening screw hereby abuts immediately against the wall of the object to be attached, and by a deeper inserted dowel also against the wall of the borehole orifice in the masonry, so as to exclude bending effects as far as possible. In addition, this design results in a very strong tensioning and wedging of the dowel material in the threaded threads, so that even exceptionally high holding forces can be obtained.
På tegningen er der vist et udførelseseksempel på forankringssættet ifølge opfindelsen.The drawing shows an exemplary embodiment of the anchoring set according to the invention.
Forankringen af dyvlen 1 ifølge opfindelsen kræver at der i væggen 2 og i genstanden 3, som skal befæstiges, er anbragt et borehul 4, som har en til den udvendige diameter af dyvlen 1 svarende diameter gennemgående over hele dens længde. Befæstigelsesskruen 5 har på dens modsat hovedet 6 vendte ende et rundgevind 7, der til formindskelse af inddrejningsmodstanden løber ud ved skruens spids 8 i en tilspidsning.The anchoring of the dowel 1 according to the invention requires that a borehole 4 having a diameter corresponding to the outside diameter of the dowel 1 throughout its length is arranged in the wall 2 and the object 3 to be attached. The fastening screw 5 has on its opposite head 6 an end of a round thread 7 which, in order to reduce the turning resistance, extends at the tip of the screw 8 in a taper.
Efter indføring af dyvlen 1 i borehullet 4 inddrejes befæstigelsesskruen 5 til forankring af genstanden 3 i dyvlen. Da kernediameteren af befæstigelsesskruen 5 svarer til den indvendige diameter af den langsgående boring 9 i dyvlen 1, graver gevindprofilet sig ved indskru-ningen af befæstigelsesskruen under samtidig fortætning og fastkiling af dyvelmaterialet mellem gevindflankerne og borehullets væg ind i dyvelformstoffet. I blødt murværk fremkommer der på grund af aksialt forløbende og i retning mod dyvlens ender begrænsede indslidsninger 10 en udspredning, der bevirker en holdekraft, som supplerer holdekraften fra udbugtninger 11 ud for gevindtoppene.After inserting the die 1 into the borehole 4, the fixing screw 5 is tightened to anchor the object 3 in the die. Since the core diameter of the fastening screw 5 corresponds to the inside diameter of the longitudinal bore 9 in the dowel 1, the threaded profile engraves itself by screwing in the fastening screw while simultaneously densifying and wedging the dowel material between the threaded flanks and the borehole wall into the dowel mold. In soft masonry, due to axially extending and towards the ends of the devil, limited incisions 10, there is a spread which produces a holding force, which supplements the holding force of bends 11 next to the threaded peaks.
Som drejesikring i bløde og til udfyldning af ind-slidsningerne 10 i hårde materialer er der langs indslids-ningerne en på langs af slidskanterne forløbende liste 12, der dels tjener til afstivning i drejeretningen,og ved forankring i hårde materialer til bedre ombøjning ind i ind-slidsningerne er forsynet med et trekantprofil.As soft turning rotation and for filling the slits 10 in hard materials, along the slits there is a longitudinal groove 12 extending along the slits, which partly serves for stiffening in the direction of rotation, and by anchoring in hard materials for better bending into the The slots are provided with a triangle profile.
Til forankring af dørrammer eller vinduesrammer kan dyvlen være forsynet med en ind i genstanden 3, som skal fastgøres, indgribende forlænget hals 13. Ved diameterforhold, som svarer til det viste udførelseseksempel mellem befæstigelsesskruen og dyvlen, er det gevindløse skaft 14 af befæstigelsesskruen 5 reduceret i forhold til den udvendige diameter af gevindet 7 med vægtykkelsen af den forlængede halsdel.For anchoring of door frames or window frames, the dowel may be provided with an elongated neck 13. engaging in the object 3 to be fixed in the case of diameters corresponding to the illustrated embodiment between the fastening screw and the dowel, the threadless shaft 14 of the fastening screw 5 is reduced. relative to the outer diameter of the thread 7 with the wall thickness of the elongated neck portion.
