Definitions

  • the invention relates to an anchoring element which can be fastened in wall surfaces for a climbing device with an internal reinforcement made of metal with at least one installation end and with an anchoring sleeve made of plastic which is firmly seated at the installation end and which has a front end cone, a middle one adjoining the end cone and with Cross ribs provided anchoring part and a rear sealing collar.
  • Stirrups with anchoring elements of this type are known, for example, from French patents 2,071,601 and 2,440,461.
  • the plastic protective cover is drawn onto a straight reinforcement bar or a reinforcement tube and then cold-formed together to form the stirrup.
  • the anchoring sleeves with a press fit are then pushed onto the free ends of the reinforcing bar in such a way that the free protective covering is sealingly covered by the free end of the anchoring sleeve.
  • the wall surfaces can consist of masonry, concrete, wood or comparable materials.
  • the anchoring element fastened by driving into boreholes in the wall surfaces or by inserting it into the concrete mass to be poured should also lie tightly against the wall surface with the sealing collar of the anchoring sleeve in order to prevent the penetration of corrosive or decomposing media into the hole wall surrounding the anchoring sleeve.
  • the present invention has for its object to provide an anchoring element of the type described above, which ensures a secure seal even with different shapes or radii of the wall surfaces.
  • the anchoring sleeve has retaining members behind the anchoring part, and that the sealing collar is designed as a soft elastic, freely adjustable and tight-fitting elastomer sleeve on the retaining members.
  • the elastomer cuff can be adapted or deformed around the anchoring sleeve, be it on a flat or curved wall surface, and thereby an effective and permanent seal can be achieved.
  • the elastomer sleeve also represents a stop for a prefabricated manhole shape.
  • the retaining members for the elastomer sleeve are formed by a large number of closely spaced, continuously circumferential circular ring ribs and grooves, while the inside of the elastomer sleeve has a number of annular grooves and ribs, which cooperate with the retaining members in a double manner to form a sealing toothing .
  • the circular ribs and grooves of the retaining members define a large number of parallel planes which are all perpendicular to the axis of the anchoring sleeve, while those through the individual inner ribs and grooves certain planes of the elastomer machine, depending on the position of the elastomer sleeve, can also run obliquely to the axis of the anchoring sleeve (FIG. 7).
  • the retaining elements have the function of sealing ribs in particular: opposite the wall surfaces if they are partly in the fastening hole for the anchoring sleeve, and opposite the elastomer sleeve if they are at least partially enclosed by the latter.
  • the retaining members have an outer diameter that is slightly, e.g. by 1 to 2 mm, larger than that of the immediately adjacent transverse rib or transverse rib segments of the anchoring part, the triangular profile of the retaining members in radial section corresponding to that of the transverse ribs on the anchoring part.
  • the retaining members consist of two groups of circular lips with different fineness and if the outer diameter of both groups is the same.
  • the first group which can consist, for example, of three to five circular, continuous circular ribs, has a coarser pitch in the axial direction of, for example, 3 to 5 mm with a depth of the grooves in between of 1.5 and 3 mm.
  • the first group is preferably also used for sealing against the wall surface or the fastening hole.
  • the second group for example, from a variety Geometrically similar circular ring lips can have a finer pitch in the axial direction, so that 20 to 40, preferably about 30 circular ring lips fall to an axial length of 30 mm, the depth of the grooves lying between being about 0.20 to 0.80 mm can.
  • This second group is preferably used for adjustment and sealing against the elastomer sleeve.
  • transverse ribs of the anchoring part by a plurality of rib segments which follow one another in the circumferential direction at short intervals, as is known per se from DE-PS 22 54 550.
  • the main advantage associated with this is that due to the subdivision of the transverse ribs into rib segments, a harder elastic starting material for the entire plastic protective jacket can be selected than would be the case with continuous transverse ribs on the anchoring part.
  • the rib segments are individually deformable and anchor themselves better in the wall hole without their Deformation would have an impact on neighboring segments.
  • the rib segments show a triangular profile, the back of which is perpendicular and the base of which is or lies parallel to the axis of the leg or anchoring sleeve.
  • the third side of the triangular profile is inclined from the outside inwards and from the back to the front to the axis of the leg.
  • a position of the connecting arms between the tread piece and the fastening legs perpendicular to the leg axes creates the prerequisite for a safe, error-free driving of the anchoring sleeves of the stirrup into the wall holes, which are known to be somewhat smaller in diameter.
  • the U-shaped stirrup 1 Seen from the outside, the U-shaped stirrup 1 according to FIG. 1 consists of two mutually parallel, horizontal fastening legs 2, 3 and a central, transversely oriented, horizontal tread piece 4 that is bent down relative to the fastening legs 2, 3.
  • the cross section of the stirrup 1 is essentially circular.
  • the stirrup 1 has a tubular or full-rod-shaped, rigid inner reinforcement 5 made of metal or a metal alloy and a protective sheath 6 surrounding the inner reinforcement 5 made of plastic, as well as, in each leg end area, an anchoring sleeve firmly seated on the inner reinforcement 5 7.
  • This anchoring sleeve 7, which is also made of plastic, has a front end cone 8, a central, possibly tapering slightly towards the front, adjoining the end cone 8, provided with transverse ribs 9, anchoring part 10 and a sealing collar 11 placed at the rear.
  • the protective sleeve 6 and the anchoring sleeve 7, with the exception of the sealing collar 11, are designed as a one-piece protective jacket 12 which surrounds the correspondingly pre-shaped inner reinforcement 5 and which, for has been applied by an injection molding process.
  • the anchoring sleeve 7 behind the anchoring part 10 has a section provided with two groups of retaining members 13 and 18, on which the sealing collar 11 designed as a soft elastomer sleeve lies tightly and is freely adjustable and in the set position by the retaining members 13 and / or 18 is held.
  • the retaining members 13 of one group are formed by a plurality of closely spaced, alternating circular ring ribs and grooves, which run continuously around the circumference of the anchoring sleeve 7 and perpendicular to its axis.
  • a number of annular ribs 15 are provided, which cooperate elastically with the retaining members 13 and / or 18 to form a sealing toothing.
  • the transverse ribs 9 of the anchoring part 7 are formed by a plurality of rib segments 16 which follow one another in the circumferential direction at short intervals, the individual rib segments lying on circles being arranged parallel to one another.
  • the rib segments 16 of adjacent transverse ribs 9 are arranged at an angle to one another, so that a gap 17 between two adjacent segments 16 of the same transverse rib 9 is covered by a segment 16 of the adjacent transverse rib 9.
  • the retaining members 18 are provided, which are likewise formed by a plurality of continuously rotating, annular ribs, the outer diameter of which is slightly larger than that of the immediately adjacent transverse rib 9.
  • the retention members 18 of the other group cover an area that is about a quarter in length up to a third of the length of the area occupied by the transverse ribs 9.
  • the retention members 13 directly adjoin the adjacent retention members 18.
  • the outer diameter of the retaining members 13 is preferably the same size as that of the retaining members 18, so that - as already mentioned - the sealing collar 11 can also seat sealingly on the retaining members 18.
  • the sealing collar 11 has a wide sealing flange 19 with a flat front surface 20 (in a relaxed state).
  • the fastening limbs 2, 3 are connected to the transverse tread piece 4 via perpendicular, downwardly bent, vertical connecting arms 21, 22, which is also essentially perpendicular to the connecting arms 21, 22.
  • each vertical connecting arm 21, 22 which has a flat stop surface 25 or 26 which is perpendicular to the axis of the leg and which corresponds to that (26 or 25) of the other connecting arm (22 or 21) associated stop (24 or 23) and serves as a protective cushion for hammer blows.
  • the stirrup described is torsion-resistant and corrosion-resistant in itself and also against the wall surfaces surrounding it. It can be hammered into wall surfaces made of concrete, masonry, wood or comparable material with the appropriate holes or inserted in prefabricated manhole forms using the wet process or installed on the construction site. Due to the previous shape of the inner reinforcement made of steel, chrome steel or aluminum (alloy) and the subsequent sheathing with e.g. molten polyethylene by means of high pressure, a homogeneous, tight-fitting elastic jacket is obtained which is neither brittle, so sensitive to impact, nor can it be infiltrated by corrosive media.
  • the anchoring sleeve 7 according to FIG. 4 is in this case designed as an individual part and can be used both in connection with a stirrup 1 according to FIGS. 1 to 3 and in connection with a ladder bracket 30 according to FIG. 6.
  • the anchoring sleeve 7 has a longitudinal bore 27 for pressing in or hammering in the installation end 5a of the internal reinforcement 5. Behind the retaining members 18 there is a cylinder surface 28, the diameter of which corresponds to that at which the retaining members 13 are located in FIG Outer diameter of the retention
  • the sealing collar 11 can at least partially support or fix sealingly on the cylinder surface 28 (see FIG. 7).
  • the cylinder surface 28 merges by means of a transition cone 29 into the end face of the anchoring sleeve 7, in which the opening of the longitudinal bore 27 is located.
  • FIG. 6 shows how the end of the inner reinforcement 5 facing away from the installation end 5a can be designed as a pipe clamp 31 for the clamping of a ladder stile 32, which is indicated by dashed lines.
  • the pipe clamp 31 consists in a conventional manner of a half-shell 31a fixedly connected to the inner reinforcement 5 and a movable half-shell 31b which can be braced by means of a tension screw 33.
  • a complete anchoring element is created by driving the inner reinforcement 5 into the anchoring sleeve 7.
  • the sealing collar 11 ( Figure 5) can then be opened from the front, i.e. slide on the end cone 8.
  • the cylindrical wall surface 34 of a shaft which is perpendicular to the plane of the drawing, is indicated by a dashed circular line, to which the axis of the anchoring sleeve 7 runs eccentrically or on a chord. It can be seen in which elastic deformation compared to the initial shape shown in FIG. 5, the sealing collar 11 can be applied to this wall surface 34 in order to ensure a tight and optically clean closure.
