Definitions

  • the invention relates to a method for anchoring floor dowels for rod-shaped objects in floors with a fixed ceiling by means of a floor dowel system and a floor dowel system for implementing the same.
  • Floor dowels are known DE 10240586A1 for fastening rod-shaped objects, e.g. B. pipe posts in the paved ground with a pipe with a cylindrical inner opening for receiving the rod-shaped object.
  • the pipe has a tip with several folds forming tapered grooves and at its upper end a flange part with a radially facing wall and a clamping plate running parallel to the flange part with a through opening that can be fastened to the flange part via clamping screws and a clamping ring Pressure-resistant and flexurally resistant material between the flange part and the clamping plate, which surrounds the post in the area of the inner opening of the flange and the passage of the clamping plate.
  • Such devices for fastening rod-shaped objects in the ground consist of a tube with a point at its front end pointing in the direction of impact.
  • a cup-shaped flange is provided at the rear end of the tube.
  • the device is supplemented by an elastic clamping element that encompasses the post between the flange part and the clamping plate, by means of which a non-positive fastening of the post is achieved by pressing.
  • a ground socket which is used for the quick-release and replaceable mounting of posts for traffic signs. It is a concreting sleeve made of a cast body. In its upper area there is a thread under which the seat of a collar-like clamping ring is located. After the seal has been inserted, a kind of hollow plug is loosely screwed into the thread. After setting in concrete and drying out, the post is inserted into the hole in the hollow plug as far as it will go. The hollow plug is then tightened with a wrench over the wrench flats, the clamping ring pressing against the post and securing it.
  • ground foundations and concreting sleeves have disadvantages, in particular the use of an unnecessarily large amount of concrete is to be criticized, which seals the ground and leads to difficulties in removing the device.
  • the method according to the invention and the floor dowel system make it possible to insert floor dowels in an aligned manner with the least amount of mortar-like material, adapted to the most varied of requirements - such as the nature of the subsoil - with an effective, cost-effective method of operation and a modular device, the dowel system, in a compact and floor-flush design .
  • a particular advantage of the invention is its aesthetically pleasing impression, which comes about through the use of pre-hole templates and excavation templates, which avoid damage to the drilling edge of the ceiling.
  • the pot of the dowel fits nicely with the hole in the ceiling, because the templates prevent damage to the ceiling through holes or further spaces.
  • the invention thus relates to a method for anchoring floor dowels for rod-shaped objects (4) in floors with a fixed surface (ceiling) (52) by means of a floor dowel system (1) with a floor tube (2) for receiving a post section that has a pot-like Mounting flange (7) in the form of a pot with a base (15) and a vertical ring wall (16), screw sleeves in the pot base (15), relief openings (17) and a closed earth end, which is open in the direction of the earth end of the floor plug, and has the steps : Producing a defined circular section in the ceiling (52); Digging a shaft (51) in the ground (50) under the circular section of the ceiling (52), the cross section of which corresponds to the circular section in the ceiling (52) and the length of which is sufficient for the floor pipe to be freely pivotable in the shaft; wherein the diameter of the circular section in the ceiling (52) is 1 - 10%, preferably 3 - 6% larger than the diameter of the pot-like fastening flange (7), so that
  • the anchor can be cast with little hardening material, because no concrete / mortar excess is necessary.
  • the concrete / mortar often used as a viscous material is not an environmentally friendly material and should therefore be used as little as necessary, which enables the invention.
  • the alignment of the dowel can be checked in the usual way by means of a spirit level or a spirit level on a rod inserted into the post opening.
  • the dowel is swiveled in the manner of a self-aligning bearing against the inner wall of the ceiling circular section and thus aligned vertically.
  • the dowel can also be rotated within the guide formed by the circular cut-out in the ceiling, if rectangular posts are to be fastened with a preferred direction - for example with traffic signs.
  • the soil pipe can be fastened after alignment without the use of unnecessarily large quantities of hardenable material.
  • an unnecessarily large amount of concrete was poured into the hollow space excavated without any special geometrical specifications - an environmentally harmful waste of material that also led to problems when aligning the dowel.
  • the dowel in the method according to the invention has only limited possibilities of movement due to the defined shaft geometry and geometry of the ceiling cutout and is pivoted against a support on the inner wall of the circular cutout in the ceiling, its alignment and its attachment by hardening the material is easy and material-saving.
  • the ground pipe can be lengthened by at least one extension pipe with a receiving opening for the ground pipe earth end and an extension pipe earth end before it is introduced into the manhole, the manhole then is excavated deeper in accordance with the geometry of the extended soil pipe, the shaft (51) being excavated correspondingly longer than the extended soil pipe (2, 20).
  • only a basic dowel of a predetermined length has to be produced, which can be extended in a modular manner by means of attachable extension tubes.
  • the floor tube (2) and / or the extension tube (20) have retaining devices which make it difficult to move, twist and pull out the floor anchor (1) against the soft material and prevent it when the material is hardened.
  • These are streamlined projections and / or depressions, around which the curable material can be surrounded without the formation of bubbles or pockets can flow and harden.
  • These retaining devices make it difficult to move, twist and pull out the floor anchor (1) against the hardening material and help maintain the aligned position until the hardening material / concrete is solid.
  • a post fastening is applied with: a clamping ring (11) for the post and a clamping plate (8) with a post opening and clamping screw bores (22) that can be screwed onto the clamping ring (11) against the fastening flange (7); Insertion of a post end through the clamping ring (11) and the clamping plate post opening (10) into the floor pipe opening,
  • clamping screws (9) are tightened against the screw sleeves in the fastening flange (7) while compressing the clamping ring (12) and frictionally engaging the post (30).
  • This tensioning device enables easy replacement of the posts and is robust against rear-end collisions - i.e. only the clamping device is deformed - the anchor remains intact.
  • a cover plate with screw holes (22) can be screwed onto the flange (7) while covering the post opening, if at present no post is included in the anchor.
  • a particular advantage of the invention is that it is now possible to insert the posts in a repeatable and automated manner.
  • standardized conditions for post fastening can be created, such as are desired, for example, for posts participating in road traffic (e.g. traffic signs) or for a uniform design of street furniture.
  • the ground pipe earth termination end is integral with the pipe (2) and has a streamlined taper, which is closed by reshaping to a round closed end or bent, cut out, unformed soil pipe sections or by a separate, aerodynamically shaped cap attached to the earth end (40) is formed.
  • the at least one floor tube (2) and / or the extension tube (20) can have anchoring elevations that are favorable to the flow of the ground for stronger fastening of the floor anchor system.
  • floor dowels are introduced with the least possible impact on the environment by a repeatable procedure and can be easily adapted to changing posts and similar rod-shaped objects or loads to be accommodated without having to operate expensive storage.
  • floor pipes of a floor plug can now be provided with extension pipes of different lengths and, if necessary, interchangeable end pieces, it is possible to create a floor plug system that can be easily adapted to the local conditions and soil conditions.
  • extension pipe at the end of the earth with a protruding anchoring bead for improved anchoring.
  • the shaft can also be widened conically downwards during its excavation, so that the hardened viscous material itself also forms a second anchoring bead or cone and the overall system has a high tear-out strength.
  • Possible materials for the system are corrosion-resistant, elastic materials, including Steel, cast iron, sintered metal, aluminum, brass and high-strength plastics.
  • the shaft can both be easily produced and the cast-in dowel can also be easily removed from the ground together with the concrete - for example by means of a corresponding Drill bit or chisel. Aligning the floor anchor against the inner wall of the ceiling circular cutout is effortless and with little effort in damp concrete - both in terms of the height and the direction and orientation of the anchor if rectangular profiles are to be used.
  • a method for aligned anchoring a ground anchor in a paved ground is shown schematically.
  • a section of a circle is produced from the ceiling 52 of a paved base by means of a drill bit.
  • a shaft 51 is dug under the circular segment of approximately the same diameter as the circular segment and approximately the length of the floor dowel.
  • Hardenable material - in this case liquid concrete - is then poured into the shaft. It is important to ensure that about as much concrete is poured in as it is The shaft volume minus the dowel volume.
  • a floor dowel 1 is now pressed into this soft concrete until its fastening flange 7 lies in the ceiling 52.
  • Its bottom pipe 2 displaces the concrete in the shaft, which flows upwards in the shaft, fills the shaft 51 up to the ceiling 52 and possibly oozes out a little over the ceiling.
  • the concrete also flows around projections on the soil pipe 2, which prevent the soil pipe 2 and the soil anchor 1 from being pulled out and / or rotated after the concrete has hardened.
  • An excess amount of concrete can be removed or can emerge through any existing relief openings 26 in the pot-like fastening flange 7 and be removed there.
  • a streamlined design of the bottom tube - for example, a rounded tip and streamlined projections - can prevent the formation of bubbles in the concrete when the dowel 1 is pressed in, thus increasing the stability and quality of the concrete casting.
  • the soil dowel 1 thus introduced into the damp concrete is now aligned vertically in the shaft - for example by means of an alignment device, known per se, which can be plugged into the soil pipe and has a circular level or spirit level (not shown).
  • the new position of the floor anchor 1 is stabilized by the tough concrete flowing in and is strengthened by the hardening.

  • the clamping and reinforcing ring 13 is designed as a symmetrical double cone and is mounted in a conical shape of the flange inner opening.
  • the bottom tube 2 and the tensioning and reinforcing ring 13 form a stable one in the uppermost area of the flange 7, ie where the greatest bending forces occur Stiffening. This stiffening is transferred to the area of the clamping plate 8, which is only a few millimeters away from the surface of the fastening flange 7 at the passage, whereby the lever arm is kept as small as possible when the rod-shaped object 4 is bent.
  • the clamping plate 8 is stiffened by a bend and has the diameter of the outer contour of the flange 7 for complete floor covering and maximum stability.
  • the floor dowel 1 which ends in a rounded tip, is inserted into an extension tube 20 widened in the upper area, which in this embodiment also has a rounded tip produced by reshaping, can be introduced and thus extends the bottom tube 2.
  • Fig. 3 shows a detail of the device for fastening rod-shaped objects 4 according to FIG Fig. 1 when closed in section.
  • the double-conical clamping and reinforcing ring 11 is approximately flush with the top of the clamping plate 8.
  • the countersunk screws 9 are as in FIG Fig. 2 tightened so that the angled clamping plate 8 is seated on the flange edge, the clamping plate 8 being pretensioned by the tightened screw.
  • FIG. 4 Another embodiment of extension tubes is shown - here with a separately designed flow-enhancing cap 40 with a circumferential anchoring bead 42, which can be screwed onto the extension tube.
  • Fig. 5 shows an extension tube with attached cap 40, the connection of which on the extension tube should in no way be limited to screwing - it can be fastened in any other way - for example by welding, soldering, press fit.
  • Figure 5a shows schematically the production of an extension tube with a molded cap 40, a round closed end of the extension tube being produced by cutting out triangular cutouts and then reshaping by pressing the cut-out extension tube end against a mold.
  • Fig. 6 represents a further part of the floor dowel system 1 according to the invention, the cover plate 60.
  • the embodiment of a cover plate shown here as an example 60 is provided for securely covering the floor plug opening when the floor plug 1 is not required for post 4. It is slightly curved and, in this exemplary embodiment, has elevations on the surface that prevent slipping on the cover plate 60.
  • Their bores 22 with depressions allow countersunk screws to be screwed in, which prevents stumbling over the dowel covered in this way and a visually appealing impression of the surface equipped with the floor dowel with cover is achieved.

  • the excavation template 56 can prevent injury to and damage to the ceiling opening.
  • the overburden is then removed from the shaft 51 ( Fig. 11 ) - this can be done manually, as shown here. However, it can also be removed using an industrial vacuum cleaner or other cleaning equipment - depending on the nature of the soil and the tools available. Then a predetermined amount of liquid concrete is poured into the opening, the liquid concrete level here being below the ceiling 52 ( Fig. 13 ).
  • the ground anchor 1 In the viscous liquid, the ground anchor 1 is pressed in, displacing the concrete ( Figs. 14, 15 ), Here some concrete escapes from relief openings 26 of the pot 7 and on the edge of the pot. The adhesive forces and the weight of the anchor 1 prevent it from floating up. As in Fig. 16 shown, an alignment rod with a circular level is then inserted into the anchor and the anchor 1 is aligned in the damp concrete. The alignment of the anchor remains due to the adhesive forces and the buoyancy of the hollow anchor 1 until the liquid concrete hardens.
