Definitions

  • the invention relates to a fastening anchor for performing work on a concrete wall or concrete ceiling.
  • a fastening anchor for performing work on a concrete wall or concrete ceiling.
  • the formwork of ceilings or floors that are placed on concrete walls is considered.
  • Such anchoring anchors can also be used in connection with suspended ceilings or for attaching pipelines to concrete walls or concrete ceilings.
  • a fastening anchor which consists of a sleeve which can be concreted into the concrete wall and has an anchoring pin made of steel which penetrates the sleeve transversely to its longitudinal direction; this anchoring pin in turn serves as an anchor for an eyelet-like fastener to be inserted into the interior of the sleeve.
  • the object of the invention is to improve this known sleeve principle in such a way that the individual parts of the fastening anchor can be manufactured more cheaply and more stably.
  • the fastening anchor which consists of a concrete that can be concreted into the concrete wall or ceiling, is provided with an anchoring element and a insertable into the concreted sleeve and lockable in the anchoring element of the sleeve
  • the sleeve is a first Section with an essentially slit-shaped cross-sectional profile and an adjoining, serving as anchoring element, second section with an expanded, preferably circular or approximately circular cross-sectional profile and that the fastening member consists of a rod or tube which has one or at its insertable end into the sleeve has several, transversely to the longitudinal direction of the rod or tube, the slot profile of the sleeve adapted anchoring members and the other, protruding from the sleeve end for a clamp or screw connection gnet is trained.
  • a clamping connection can be carried out with the fastening member
  • its end protruding from the sleeve is expediently eyelet-shaped, for. B. for pressing a wedge.
  • the end of the fastening member protruding from the sleeve has an internal or external thread.
  • the sleeve For better anchoring of the sleeve in the concrete, it is advisable to provide it with a reinforcing flange at its end, namely on the part which has a circular or approximately circular cross-sectional profile. Furthermore, it is advisable to provide that cavity of the sleeve, which has a circular or approximately circular cross-sectional profile, with one or more transverse limiting tabs, which then serve as a stop for the rotational movement of the fastening element to be inserted.
  • the sleeve itself is expediently made of plastic, namely by injection molding. It is provided with access covers on both sides, which are adapted to the respective cross-sectional profiles.
  • the invention Compared to the known fastening anchor consisting of a sleeve and a fastening element, the invention has the advantage that the slot-shaped profile of the front part of the sleeve only results in a smaller opening in the concrete wall than in the known arrangement. Since the central bulge of the slot only needs to be so large that the shaft of the fastening element has about a play of 1 mm, a guide for the fastening element is also provided inside the sleeve.
  • the fastener to be inserted into the sleeve is expediently made of malleable cast iron.
  • this link from normal steel or even from flat iron, in which case the stamping method would be used in the production. 5 - 10 mm thick flat iron could be used as the starting material for this.
  • FIG. 1 of the drawing is a side view

  • the sleeve to be concreted into the wall is designated 13. It consists of the two sections 1 and 2, which merge into one another. These two sections differ from each other in their profile.
  • the profile of section 1 is approximately slot-shaped, as can be seen in FIG. 2.
  • the adjoining profile 2, on the other hand, is circular or approximately circular.
  • Both resulting openings of the sleeve 13 are covered by the cover 3 and 3a. While the cover 3a only has the task of closing the sleeve 13 against the penetration of concrete, the cover 3 is used to hold the sleeve 13 during the concreting process. Accordingly, the cover 3 has a thickness of approximately 20 mm. It is attached to the formwork board with the help of pins or nails, then the sleeve is attached to the cover 3.
  • FIG. 3 From Fig. 3 the formation of an eyelet-like fastening member 14 can be seen, which is inserted into the concreted-in sleeve 13.
  • This link consists of the eyelet 5, a shaft 6 and an anchoring pin 7.
  • these parts can be manufactured individually and then assembled, for example by welding the tubular shaft 6 into the eyelet 5 and then the Pin 7 is driven into a bore in the shaft 6.
  • the part shown in FIG. 3 will expediently be produced in one operation, for example in malleable cast iron.
  • Fig. 4 is the application of an attachment consisting of the parts shown in Figs. 1, 2 and 3 anchor explained.
  • the eyelet-like fastening member 14 is inserted into the sleeve 13 concreted into the concrete wall 8, such as a key in a keyhole. After insertion of this link, it is rotated by 90 °, so that the anchoring pin 7 is locked in the sleeve part 2.
  • the formwork board 10 can then be attached to the concrete wall 8 and wedged using a further spacer 15 and a U-rail 11 using a wedge 12 inserted into the outer part 5.
  • the wedge 12 After pouring the ceiling to be placed on the concrete wall, the wedge 12 is knocked out so that the formwork board 10 can be removed. Subsequently, the eyelet-like fastening member 14 is removed from the sleeve by rotation through 90 ° and the sleeve opening is closed with the aid of the cover 3.
  • FIGS. 5 and 6 are perspective representations of the sleeve shown in FIGS. 1 and 2 in a view drawn on a smaller scale than in FIGS. 1 and 2.
  • Fig. 7 another embodiment of a fastening member is drawn and in Fig. 8 the attachment of a casing with such a fastening member.
  • the circular cross-sectional profile 2 has a reinforcing flange 16 on its outer edge.
  • one or more limiting tabs 17 are provided, which serve as a stop.
  • the sleeve is provided on both open sides with caps 3 and 3a, the shape of which is adapted to the cross-sectional profiles.
  • Fig. 7 an embodiment for the fastening member is drawn, which is inserted into this sleeve after concreting the sleeve shown in Figs. 1, 2, 5 and 6.
  • This fastening member is composed of the two parts 18 and 19, the part 18 is expediently made in malleable cast iron and carries the anchoring member 20 at its end.
  • the diameter of the shaft 18 must be smaller than the inner diameter 4 of the sleeve part 1 (FIG. 2) so that this part can be rotated after it has been inserted into the slot-shaped part 1 of the sleeve.
  • the anchoring member 20 has a span, which must be less than the inner diameter of the circular sleeve part 2.
