Definitions

  • the invention relates to an anchor bolt for anchoring with a bore, with a clamping bolt which has a threaded section with a head section which is widened conically therefrom, and a sleeve with an internal thread section and an adjacent, sector-shaped anchoring section.
  • Such an anchor bolt is known for example from DE-OS 28 34 241.8 of the applicant.
  • additional anchoring such as with soft or brittle materials. With such materials, either the case may occur that the sleeve is not sufficiently held in the bore receiving it, so that it rotates when trying to tension the anchor bolt, or that the expanded sleeve does not find sufficient support in the wall material of the bore and is pulled out.
  • the invention is therefore based on the object of improving the mountability and pull-out strength of the generic anchor bolt.
  • a further anchoring element is, for example, a further clamping bolt which largely corresponds to the clamping bolt which is present anyway, but does not have a head, but instead has a threaded blind hole entering from the rear end.
  • the front threaded section of the other clamping bolt can be screwed into this threaded hole as far as it will go, so that both clamping bolts can be rotated as one unit.
  • An expandable sleeve is also provided on the threaded section of the further clamping bolt, so that two sleeves can be expanded simultaneously.
  • a further anchoring element can consist of a sleeve made of sheet metal, plastic or the like, which can be contracted and thus expanded in the axial direction, which has a threaded section in the front end face and surrounds the arrangement of the tensioning bolt and the expandable sleeve before assembly.
  • additional sleeves are suitable, for example, for anchoring to hollow walls.
  • the lengthening threaded section can also be formed on the anchoring member itself and can be screwed into the front end of the sleeve.
  • additional anchoring members can be provided in particular if the fixing of the sleeve in the direction of rotation is to be improved. This can be the case, for example, with gas concrete or other porous building materials.
  • FIG. 1 illustrates in a partial representation a first embodiment of the invention
  • Fig. 4 schematically illustrates a third embodiment of the invention
  • Fig. 1 there is first a clamping bolt on the right side
  • clamping bolt 10 shown with an expandable sleeve 12 This arrangement of clamping bolt and sleeve is known as such from the aforementioned DE-OS 28 34 241.
  • the threaded portion 14 of the clamping bolt 10 has a greater length, so that it emerges from the sleeve 12 to the front even when it is not expanded.
  • Additional anchoring members can be provided on the free end of the threaded section 14 protruding forward from the sleeve 12.
  • the front end of the threaded portion 14 carries a further clamping bolt 16, which differs from the clamping bolt 10 in that a head 18 is missing and instead a threaded blind hole 20 in the rear end face of the enlarged Kopfab section 22 is provided.
  • the head section 22 merges into a threaded section 24 in a conical surface 26.
  • the threaded portion 24 in turn carries an expandable sleeve 28 which corresponds to the sleeve 12.
  • the sleeves 12 and 28 are preferably rotated onto the threaded section 14 and 24 into the rear end position, preferably outside of a borehole, and the threaded section 14 is screwed in to the bottom of the threaded blind bore 20. After insertion of the entire arrangement, both clamping bolts 10, 16 can be rotated synchronously with one another, so that the remaining sleeves 12, 28 are spread synchronously.
  • the chain of clamping bolts and sleeves can be extended further in a corresponding manner if necessary.
  • FIG. 2 and 3 show the anchor bolt according to the invention in combination with an additional anchoring sleeve 30, which is suitable for cavity walls.
  • the anchoring sleeve 30 consists in particular of sheet metal or plastic and has a number of longitudinal slots 32 which permit extensive expansion according to FIG. 3.
  • a threaded section 36 which interacts with the front end region of the threaded section 14 of the clamping bolt 10 (FIG. 3).
  • hooks 83 At the rear end of the anchoring sleeve 30 there are hooks 83 which serve for anchoring in the material of the wall 40.
  • the sleeve 12 When the clamping bolt 10 is turned, the sleeve 12 is raised according to FIG. 3. At the same time, it presses the anchoring sleeve 30 outwards, which, however, is additionally compressed and thus spread by the interaction of the threaded section of the clamping bolt 10 and the threaded section 36 in the bottom 34 of the anchoring sleeve.
  • the anchoring sleeve 30 finally takes on a mushroom-like shape, which enables secure anchoring behind hollow walls 40.
  • FIG. 4 time an alternative embodiment of the invention, in which the threaded portion of the clamping bolt, not shown here, does not protrude forward over the sleeve 12, but is so short in relation to the sleeve that it has its front end in the expanded state of the sleeve not reached.
  • an anchoring wedge 42 is screwed into the threaded section of the sleeve 12 from the front, on the rear side of which there is a short threaded stub 44 which is screwed into the sleeve 12 from the front as far as it will go can.
  • This anchoring wedge digs sharply into a wall material, particularly porous wall material, and prevents the sleeve from rotating when the clamping bolt is tightened.
  • the anchoring wedge may also have a different, sharp-edged cross-sectional shape, e.g. Have a star shape or the like.
  • the cross-sectional shape of the anchoring sleeve is preferably polygonal. This means in particular that a round or only slightly corrugated cross-sectional shape of the anchoring sleeve is not sufficient for a secure fixing in the direction of rotation.
  • the cross section of the anchoring sleeve allows numerous modifications. For example, the sides of the polygon can be slightly curved inwards or outwards. Cross-sectional shapes with sharp-edged outer contours are preferred.
  • the conical shape at the transition between the head section and the threaded section of the clamping bolt also permits certain modifications compared to the exact shape of the truncated cone.
  • fillets can be provided at least in the transitions between the threaded section, the cone and the head section.
  • FIG. 5 shows a further exemplary embodiment of the invention, in which the additional anchoring member is designed as a clamp 68, which extends from the end face over the sleeve and whose legs extend in the longitudinal direction on the outer surface of the anchor bolt.
  • This embodiment is specifically intended for such bolt connections in which a rotationally fixed connection of the components to be connected is important, for example for fastening furniture knobs to a door or feet on a base part of a piece of furniture or for fastening rungs of a shelf construction in which the Anchoring takes place from the front of the rung.
  • FIG. 1 shows the attachment of a furniture knob 50 to a door 12 with the help of an anchor bolt 54 according to the invention, which projects into a blind hole 51 of the furniture knob.
  • the anchor bolt 54 comprises a clamping bolt 56 with a threaded section 58 and a conically widened head region 60 with a countersunk head 62, and a sleeve 64 with a spread anchoring region split into individual claws 66.
  • the U-shaped bracket 68 extends over the bottom of the blind hole
  • the two legs of the bracket 68 extend on the outside of the sleeve 64 through a space formed between the spread claws 66 and protrude laterally of the anchor bolt 54 into a bore 53 in the door 52.
  • the distance between the outer edges of the both legs of the U-shaped bracket 68 is slightly larger than the diameter of the blind bore 51 and the bore 53.
  • the two legs are held apart by the sleeve 54 or by the clamping bolt 56 and are in the wall of the holes 51,53 forming Wood of the furniture knob 50 or the door
  • the legs of the bracket 68 are fixed in this manner in a rotationally fixed manner with respect to the furniture knob 50 and with respect to the door 52. Since the legs of the bracket 68 are embedded in the surrounding material, bending them is practically impossible. In this way it is prevented that the furniture knob 50 can be rotated with respect to the door 52. In particular, this precludes the furniture knob, together with the sleeve 64, from being unscrewed from the threaded section 58 of the clamping bolt 56.
  • the clamping bolt 56 is rotatable between the legs of the bracket 68, the furniture knob can be unscrewed from the inside of the door 52 with the aid of a screwdriver engaging the countersunk head 62.
  • the embodiment of the anchor bolt according to the invention, the mode of operation in Figure 1 was illustrated by the attachment of a furniture knob on a door, can also be used for the rotationally fixed connection of other components that can also consist of materials other than wood.
  • the sleeve 64 the claws 66 of which are not yet spread apart, is struck together with the partially screwed-in clamping bolt 56 and with the clamp 68 attached through the mutually aligned bores of the components to be connected. Subsequently, the clamping bolt 56 is further screwed into the sleeve 64 in the usual manner, thereby spreading the claws 66 for anchoring this sleeve.
  • FIGS. 6 and 7 show a view and a cross section of the clamp 68, which is formed by a U-shaped wire with a diamond-shaped or square cross section.
  • the sleeve 64 preferably has a number of grooves 70 on its outer surface, which extend over the entire length of the sleeve 64.
  • the grooves 70 serve on the one hand to weaken material in the anchoring area of the sleeve 64 in such a way that the anchoring area tears open along these grooves due to the internal pressure of the clamping bolt 56 and divides into individual claws 66.
  • the grooves 70 give the legs of the U-shaped bracket 68 guidance. As shown in FIG.
  • the limbs of the clamp 68 engage with one edge each in one of the grooves 70 and thus form a toothing of the sleeve 64 with the wood surrounding it. This prevents the sleeve 64 from rotating when the clamping bolt 56 is screwed in.
  • the diamond-shaped or square cross section of the legs of the clamp 68 also facilitates the penetration of an edge of these legs into the material of the components to be connected to one another.
  • FIGS. 8 and 9 show another embodiment of the clip which extends over the sleeve 64.
  • the perspective in Figure 8 The clip shown and designated 32 has a plurality of legs 74 and is made from a sheet-metal stamped part 72 'partially shown in FIG.
  • the stamped part 72 ' comprises an annular central region 76 *, from which radiate strips 74' extend.
  • the strips 74 ' are angled in the manner shown in FIG. 8 and then form the legs 74 of the clamp 72.
  • the number of legs 74 is in principle arbitrary, but preferably corresponds to the number of claws 66 or grooves 70 of the sleeve 64.
  • FIG. 1 Another exemplary embodiment of the anchor bolt according to the invention is shown in FIG.
  • an anchor bolt 84 projects into an end blind bore 81 of a rung 80, for example a shelf construction.
  • the rung 80 is fastened in a rotationally fixed manner to a spar 82 with the aid of the anchor bolt 84.
  • the anchor bolt 84 differs from the anchor bolt 54 shown in FIG. 5 in that the tension bolt is designed as an elastically stretchable tension member 86. The remaining parts of the anchor bolt that are already known from the preceding description should not be discussed again.
  • the tension member 86 comprises a clamping piece 88 with a threaded section 90 and a conically enlarged section 92 and a bolt 94 with a threaded section 96, a conically enlarged section 97 and a countersunk head 98.
  • the enlarged section 92 of the clamping piece 88 has a recess 100 in an end face .
  • the recess 100 has a circular cross section and is provided with an internal thread.
  • the threaded portion 96 of the bolt 94 is screwed into the nut 102.
  • a suitable, for example hexagonal cross-section of the recess 100 in the area of the nut 102 prevents the nut 102 from being caught in the Screwing the threaded portion 96 rotates.
  • a ring 104 with an external thread is screwed into the threaded section of the recess 100.
  • the threaded section 96 is surrounded in the area between the nut 102 and the threaded ring 104 by a number of curved clamping rings 106 which press the nut 100 and the threaded ring 104 apart. If the bolt 94 with the threaded section is screwed further into the nut 102, the distance of this nut from the threaded ring 104 is reduced and the clamping rings 106 are elastically deformed.
  • the clamping piece 88 is displaced in the direction of the bolt 94 by the force of the clamping rings acting on the threaded ring 104. Since the clamping piece 88 is fixedly connected to the rung 80 by the sleeve 64, the rung 80 is tensioned against the spar 82 in this way.
  • the bracket 68 ensures that the rung 80 cannot be rotated about its longitudinal axis.
  • the embodiment of the anchor bolt according to the invention shown in FIG. 10 offers the advantage that the one produced between two components Connection is flexible but non-rotatable.
  • the elastic tension member can also be formed in that an elastic connecting piece is fastened between two legs of a tensioning bolt, which can be made of spring steel, for example, and is shaped in such a way that it also fits the head region of the head Torque acting torque can not be rotated.
