Definitions
- the invention relates to a fastener with the features of the preamble of claim 1.
- Such a fastener for anchoring in a borehole is known from the published patent application DE 40 11 229 A1.
- the fastener shown in this document is particularly suitable to plate-like components, such as natural stone slabs to attach to a load-bearing construction.
- the fastening element is designed as an undercut anchor and has a shank portion and a spreading element. At the shank portion, a spreader widening in diameter is arranged at its introduction end at the front end, with which the spreader element can be expanded.
- the shank portion also has a load engaging means at a rear part.
- the expansion element consists of a wire ring with bent towards the front, in the direction of the expansion body arcuate Sp Drjopen with two webs, which are connected by a U-shaped yoke at the front end.
- the U-shaped yoke is in an unexpanded state on the spreader.
- On the shank portion of the fastener also an expansion sleeve is arranged. If the expansion sleeve is moved in the axial direction along the shaft section in the direction of the conical expansion body, then the expansion sleeve pushes the expansion element over the expansion body widening in the insertion direction, whereby the expansion lugs are spread open in such a way that they at least partially fill the undercut of a borehole. By spreading the Sp Drownlappen the fastener is anchored positively in the borehole.
- a drilling tool For the production of the well, a drilling tool is used which, depending on the degree of wear, creates a relatively wide or narrow hole. In the case of a relatively wide borehole, it may occur in the known fastening element that the expansion element does not completely bridge the space between the expansion element and the wall of the borehole so that the fastening element does not have a firm seat in the borehole.
- the object of the invention is therefore to provide a fastener for the tolerances of the drilling tool are not critical. This object is achieved by a fastener with the features of claim 1.
- the fastening element according to the invention for anchoring in a borehole comprises a shank portion and a spreading element. An expansion body for spreading the expansion element is arranged on the shaft section.
- the shaft portion is in particular designed as a cone bolt, with a conical, in particular truncated cone-like expansion body, which widens in the insertion direction and is arranged on the insertion side front end of the shaft portion.
- the shank portion also has a load engagement means, such as a thread.
- the expansion element is typically sleeve-shaped, wherein "sleeve-shaped" means that the expansion element substantially surrounds the shaft section in the circumferential direction
- the spreader element has a plurality of arcuate spreader tabs, one spreader tab each being formed by two webs connected by a yoke, in particular the webs and the yoke of a spreader tab
- the webs of the expansion tabs jointly clamp a lateral surface of the expansion element, which is rotationally symmetrical to the longitudinal axis of the fastening element or cone.
- Characteristic of the fastening element according to the invention is the special design of the yoke of one or more of the expansion lugs.
- the yoke of at least one expansion lobe has a curvature which projects beyond the lateral surface in the radial direction.
- the radial extent of the yoke is greater than the thickness of the material of the yoke in the radial direction, whereby it is achieved that a part of the expansion lobe in the region of the yoke in the expanded state further projects into the borehole, in which the fastening element is introduced.
- the expansion tab can thus bridge the space between the borehole wall and the spreader in a relatively wide hole, so that the fastener has a tight fit in the borehole.
- the yoke forms the front end of the expansion lobe.
- the expansion lobe when the expansion lobe is spread, the yoke widens furthest in the radial direction from the longitudinal axis of the anchor and is moved furthest toward the borehole wall.
- the apex of the arcuate curvature is directed radially outwardly away from the spreader body. The apex of the vault is then as the first part of the yoke on a borehole wall.
- the arcuate curvature extends substantially in the circumferential direction.
- the curvature is uniaxial and bridge-shaped in the circumferential direction.
- the curvature acts in the radial direction due to its geometric configuration as a spring.
- the curvature extends substantially in the manner of a bridge in one direction, for example in the circumferential direction, the curvature acts as a leaf spring.
- the fact that the curvature acts as a spring in the radial direction has the advantage that the yoke can adapt to the size and shape of the borehole during spreading. If the yoke had been adapted to the size of a large borehole only by material thickening or massive embossing, then this would result in additional undesirable expansion forces in a narrow borehole if the fastener were to be completely distended.
- the buckle Due to the geometric configuration of the buckle as a spring adjustment with relatively little force is possible.
- the spring is compressed radially into a narrow hole without any spreading forces of appreciable size.
- the curvature is relatively elastic and easily deformable, so that it acts even at low forces in the radial direction as a spring.
- the expansion tab is designed such that the expansion tab tapers in the direction of its free end.
- this is the webs connecting Yoke U- or V-shaped and forms the feed side front end of the expansion lobe.
- the expansion element of the fastening element according to the invention has a closed, annular base body at its rear end in the direction of insertion, on which side the expansion tabs are arranged.
- the closed body ensures that the spreader is not pulled over the spreader even at high loads and the fastener is securely anchored.
- the expansion element of the fastening element according to the invention is a stamped part, in particular a stamped and bent part, which is made of metal. This allows a simple and inexpensive production of the expansion element and the fastening element according to the invention.
- Figure 2 is a partially sectioned view of the fastener.
- the figures show an inventive fastener 1 in an unexpanded state, as it can be inserted in the direction of the direction of insertion E in a not shown well.
- the introduction direction E is parallel to the longitudinal axis A of the fastening element 1.
- the fastening element 1 is formed as an undercut anchor for anchoring in an undercut hole, not shown.
- the fastening element 1 consists of a shaft portion 2, a spreader 3 and an expansion sleeve 4th
- the shank portion 2 is a cone bolt with a cylindrical portion 5 and a conical portion 6 adjoining it on the insertion side, the diameter of which increases in the direction of insertion E.
- the conical portion 6 forms an expansion body 8, which is formed as a truncated cone and which forms the front end of the shaft portion 2.
- the expansion body 8 By the expansion body 8, the expansion element 3 is spread when it is pushed in the direction of the insertion direction E on the conical section 6.
- the cylindrical portion 5 has a load engagement means 7 in the form of an external thread.
- the load application means 7 serves, for example, for fastening the fastening element 1 to a load-bearing construction (also not shown).
- the expansion element 3 has at its rear end an annular base body 10, which comprises the cylindrical portion 5 of the shaft portion 2 as a closed sleeve annular.
- On the main body 10 are four spreading tabs Einbring detox arranged 11 which are spaced apart by recesses 12 in the circumferential direction.
- the expansion tabs 11 each have an opening 13 in the form of an all-round opening, which is arranged approximately centrally in the respective expansion tabs 11.
- the Sp Drettilappen 11 are thus arcuate, wherein a Sp Dr Dr 11 is formed by two webs 14 and a U-shaped yoke 15, wherein the yoke 15, the two webs 14 connects to each other.
- the yoke 15 forms the front end of the Sp Schwarzlappens 11, which tapers due to the U-shaped configuration of the yoke 15 in the direction of its front end.
- the webs 14 of the expansion tabs 11 together span a lateral surface M of the expansion element 3, which is rotationally symmetrical to the longitudinal axis A of the fastening element 1 and conical. In other words, the webs 14 lie on the lateral surface M of a body rotationally symmetrical to the longitudinal axis.
- the yoke 15 has an arcuate curvature 17, which projects in the radial direction R over the lateral surface M and extends substantially uniaxially in the circumferential direction.
- the vertex 18 of the bulge 17 has in the radial direction R outwardly from the spreader 8 away.
- the outwardly projecting curvature 17 acts in the radial direction as a leaf spring, which can compensate for tolerances in the width of the borehole.
- the radial extent of the yoke 15 is greater than the material thickness of the yoke 15, so that the apex 18 of the bulge 17 rests against the borehole wall even with a relatively wide borehole.
- the leaf-spring-like curvature 17 is compressed in the radial direction, so that the expansion element 3 also passes over the expansion body 8 as planned in a narrow borehole can be pushed without undesirable large constraining forces arise in the material of the borehole wall.
- the curvature can be relatively easily compressed in the radial direction.
- Wire-like here means that the yoke 15 has a cross-section whose dimensions are relatively small relative to the extent of the yoke 15.
- the ratio of the extent Aj of the yoke 15 in the circumferential direction to Material thickness dj of the yoke 15 in the radial direction R is about 2.5 / 1.
- the expansion sleeve 4 is formed as a hollow cylindrical body, wherein the cavity formed as a cylindrical bore 16 has an inner diameter substantially equal to the outer diameter of the cylindrical portion 5 of the shaft portion If the expansion sleeve 4 is displaced in the direction of the insertion direction E by an axial force, which is applied, for example, by an impactor, not shown, the expansion sleeve 4 pushes the expansion element 3 over the expansion body 8, so that the expansion tabs 11 in the radial direction R be spread.
- the fastener 1 In order for a set in a borehole and splayed fastener 1, a nut, not shown, can be screwed onto the designed as an external thread load engagement means 7, without the fastener 1 rotates in the borehole, the fastener 1 has a rotation.
- the first part of the rotation is a nose-like increase 9 on the conical portion 6 of the expansion body 8.
- the anti-rotation transmits a torque applied by a nut on the spread spreader 3 by frictional engagement on the borehole wall, not shown. Since the expansion element 3 of the fastening element 1 according to the invention rests firmly against the borehole wall due to the curvature 17, co-rotation of the fastening element 1 in the borehole is reliably prevented.
- the expansion element 3 of the fastener 1 is made as a stamped bent part of metal.
- the shank portion 2 is also made of metal and is produced inexpensively by cold mass forming.
- the expansion sleeve 4, however, consists of a fiber-reinforced plastic and is produced by injection molding.
- the Fastening element according to the invention is inexpensive to produce and due to its design powerful and easy to assemble.
