Definitions

  • the invention relates to anchoring for crampons in parts of concrete or the like. With built-in parts to be fastened to a formwork, the crampons being connected to the built-in parts after the formwork has been removed.
  • an installation part made of a material with at least the compressive strength of concrete is arranged for each crampon with a fastening flange and a screw connection, and in that the installation part has a basic body running parallel to the fastening flange, which on its after Formwork visible side has three fastening points for the crampon as well as on its opposite concrete side at least one pullable dowel as the upper fastening point for the bolt-through screw connection and two pressure and thrust abutments as further, lower fastening points.
  • the installation part according to the invention can already be attached to a concrete wall with the permissible minimum wall thickness of approximately 80 to 100 mm, which is not possible with the two installation parts of the known anchoring.
  • DE-GM 77 12 733 describes anchor anchors which can be flush-mounted in a concrete structure for the subsequent fastening of connecting elements.
  • these anchor anchors are exposed to uncontrollable tensile, compressive and shear loads.
  • a crampon anchoring based on this principle would also be quite expensive because of the numerous welds on the built-in part and because of the large number of anchor dowels required for a crampon, in contrast to the anchoring for crampons according to the invention, and therefore unprofitable when used in large numbers.
  • a crampon can be attached to a concrete wall, as described for example in DE-PS 26 50 180.
  • a single screw is sufficient as a screw connection.
  • the abutments can be adjusted accordingly.
  • the dowel engages in the base body of the built-in part and is held in the bore by friction. This means that the anchorage can be pre-assembled before it is transported to the construction site. In addition, the dowel no longer needs to be specially secured against accidental falling out or sliding after the installation part has been attached to the formwork.
  • a wart-like projection forms an abutment on the built-in part behind the depressions on its concrete side.
  • the built-in part has on its concrete side wall-projecting strips with preferably dovetail-shaped cross-section as an abutment.
  • these strips serve to stiffen the base body of the built-in part against bending and / or twisting thereof.
  • the visible side of the built-in part after stripping is designed as a cylindrical surface, and that the surface of the mounting flange of the crampon which is in the position of use is curved accordingly.
  • This is a preparatory measure for a possible attachment of a crampon to a domed one, in particular concave wall surface, such as shaft walls or the like.
  • the built-in part rests on the formwork with a small area, but with a high surface pressure, when it is attached to it by means of tacking nails or the like, and thus prevents the flow of cement slurry onto the area of the base body framed by the web, where after stripping the surface of the mounting flange of the crampon comes to rest. This area then does not need to be specially cleaned.
  • the circumferential web would be an obstacle when the built-in part was shuttered. According to the invention it is therefore provided that a predetermined breaking line is provided between the web and base body of the built-in part, along which the web can be broken off if necessary. Then the surface of the base body lies directly against the formwork when the built-in part is shuttered.
  • the entire anchorage can be attached to such formwork by holding it to the formwork with the aid of a screw inserted through a hole in the formwork and screwed into the dowel.
  • the built-in part is made from an injection-moldable material, in particular from a thermosetting or thermoplastic.
  • a thermosetting or thermoplastic in particular from a thermosetting or thermoplastic.
  • FIG. 1 shows a built-in part 3 according to the invention with a dowel 10 passing through it in a bore 16 before being encased in the negative formwork for a wall 2, in particular a concrete wall or the like.
  • the commercially available dowel 10 has, at its end concreted in in the use position, a hook-shaped pinch 11 to increase its mounting in the wall 2 and an internal thread 14 formed on the end thereof from the front side thereof for a screw bolt 15 to be screwed into it.
  • the bore 16 of the installation part 3 has a shoulder 17 at about half its length, against which a collar 18 formed on the dowel 10 can be supported in the direction R, so that the dowel 10 against further pulling out in the direction R from the opening 16 of the installation part 3 is secured, as shown in Figs. 2, 4 and 13.
  • the installation part 3 also has two blind hole-like depressions 5, 6 arranged at a distance A from one another near its ends 19, 20.
  • two appropriately designed cams 7, 8, which are also arranged at a distance A from one another, of a crampon 9 to be attached to the mounting part 3 are mounted in such a way that the latter is fixed to the mounting part 3 in a manner that is safe from tipping and tilting, as shown in FIG. 13.
  • the installation part 3 has reinforcements 21, 22, 23 and reinforcing ribs 24, 25, 26, each with a dovetail cross-section, on its concrete side 37 in the region of the recesses 5, 6 and the bore 16, as shown in FIGS. 2 to 6.
  • the latter increases the dimensional stability of the built-in part 3.
  • this increases the adhesive surfaces of the built-in part 3, which are important for an intimate and permanent connection with the material of the wall 2 touching the built-in part 3 in its position of use.
  • the reinforcements 21, 22, 23 on the rear of the built-in part 3 ensure that the edges of the recesses 5, 6 provided on its front side do not break out if the cams 7, 8 of the crampon 9 attached to the mounting part 3 should exert particularly high loads on the edges of the recesses 5, 6 due to exceptional load cases.
  • the built-in part 3 still has two holes 27, 28 which penetrate it completely for nails or the like (not shown specifically here), by means of which the built-in part 3 on the negative formwork for the Wall 2 is tacked before it is made to fix it where it will be used later.
  • a crampon 9 in the Fjg. 7 and 8 are mostly used in manholes that are round in cross-section and have a diameter of, for example, 1000-1200 mm
  • the surface of the mounting flange 29 facing the shaft wall 2 is curved with a corresponding radius S.
  • the counter surface 30 corresponding to this surface of the fastening flange 29 can also be curved on the mounting part 3 with a corresponding radius S, if one so wishes.
  • the like. which are to be attached to a wall 2 by means of the inventive anchor 1, have on their wall facing side is usually an opening 31, preferably circular cross-section , through which the screw 12 can be passed, as shown in FIGS. 9 and 10.
  • a slot 32 which is open at the top in the position of use instead of an opening 31, without thereby affecting the safety of the holder and thus even the safety of people who would climb these ladders.
  • the embodiment with a slot 32 open at the top has the advantage that the S dough iron 9 can be assembled or removed without the screw connection 12 having to be opened completely, as is the case, for example, with a crampon 9 with a closed opening 31.
  • a recess 33 should be formed at the opening 31 or the slot 32 in order to offer the screw head or the nut of a screw connection 12 a smooth bearing surface 34, so that the screw connection 12 really is only subjected to tension and not additionally to bending.
  • the latter would be the case if the bearing surface for the screw head or the nut of a screw connection 12 were inclined with respect to the axis of the screw connection and the screw head would therefore only rest on one side.
  • the installation part 3 is provided on its side facing the crampon 9 to be fastened with a circumferential web 4, the circumferential edge of which - in contrast to the surface 30 arched with the radius S in the embodiment described above - lies in a flat surface .
  • a predetermined breaking line 36 is provided along the seam line between the web 4 and the surface 30, along which the web 4 can be broken off by means of a simple tool. If the installation part 3 were to be let in on a concavely curved wall surface, the web 4 could be a hindrance, at least in the formwork. In this case, the web 4 can be removed by breaking off along the predetermined breaking line 36.
  • the built-in part 3 can - in contrast to the embodiment of the subject matter of the invention described above and shown below in the drawing - have any other appropriate and reasonable shape and size, provided the type and size of the object to be fastened to it require this.
  • it is preferably made of a temperature, form, acid, alkali sea water and / or UV radiation resistant to hydrocarbons Stable, insensitive to mechanical stress, in particular impact-resistant material, especially made of plastic or metal.
  • the installation part 3 of the anchoring 1 according to the invention should preferably be made of a plastic made of a thermoset or thermoplastic.
  • other commercially available plastics can also be used here, provided that they only meet the requirements placed on them, as formulated above.
  • the anchoring according to the invention can also be applied to curved wall surfaces. It can be used on precast concrete elements, on manhole rings, dam structures, lock walls, on the wall surfaces of sewage treatment plants, supply tunnels, silos, towers and other structures in civil engineering.
