Definitions

  • the invention relates to a method and a device for anchoring ground anchors for rod-shaped objects, in particular posts and a ground dowel system for performing the same.
  • a ground socket which serves for quickly exciting and interchangeable receiving posts for traffic signs. It is a concreting sleeve of a cast body. In its upper part there is a thread under which the seat of a sleeve-like clamping ring is located. After the seal is inserted, a kind of hollow plug is loosely screwed into the thread. After setting in concrete and drying, the post is inserted into the hole of the hollow stopper in abutment. The hollow stopper is then tightened with a wrench over the wrench flats, pressing the clamping ring against the post and securing it.
  • ground dowels Apart from the attachment of a post in the ground dowel there is the problem that soil dowels of different lengths and shapes are needed. Furthermore, in a subsoil in which many supply lines run, a ground dowel should not damage them during insertion. Finally, since the ground dowels are cast in hardening material, such as concrete, the casting of viscous material promoting same configuration desired so that when introducing the anchor into the concrete no stability of the encapsulation affecting air bubbles remain in the concrete, but the concrete bubbles connects to the bottom tube of the anchor. In addition, the posts from the ground dowels should be reversibly removable - for example, if the post for work in the way or should be introduced only temporarily or damaged / kinked. Another problem is the orientation of a dowel, so that a post can be introduced vertically - this was previously problematic, as frequently deflecting objects prevented the vertical insertion when driving a dowel into the unpaved surface.
  • the inventive method and the ground dowel system is an aligned introduction of ground dowels with the least amount of mortar-like material adapted to a variety of requirements - such as the surface texture - with an effective, cost-effective operation and a modular device, the anchor system, in a compact and flush construction ,
  • a particular advantage of the invention is its aesthetically pleasing appearance, which is achieved by the use of pre-hole templates and excavation templates which avoid damaging the bore edge of the ceiling.
  • the pot of the dowel closes in an appealing manner with the hole in the ceiling, because of the templates damage to the ceiling by pre-puncture or further spaces is avoided.
  • the invention thus relates to a method for anchoring ground dowels for rod-shaped objects (4), in floors with a fixed surface (ceiling) (52) by means of a ground dowel system (1) with a bottom tube (2) for receiving a post portion, the cup-like Mounting flange (7) in the form of a pot open in the direction of the ground end of the ground anchor with a bottom (15) and a vertical annular wall (16), screw sleeves in the bottom of the pot (15), discharge openings (17) and has a closed end, with the steps : Making a defined circular cutout in the ceiling (52); Digging a shaft (51) in the bottom (50) below the circular section of the ceiling (52) whose cross section corresponds to the circular cutout in the ceiling (52) and whose length is sufficient for the bottom tube in the shaft is free to pivot; wherein the diameter of the circular section in the ceiling (52) by 1-10%, preferably 3- 6% greater than the diameter of the cup-like mounting flange (7), so that the dowel in the shaft (51) by 10
  • the dowel can be cast with little hardening material, because it is no concrete / mortar excess 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, what the invention allows.
  • the alignment of the anchor can be controlled in the usual way by means of a spirit level or a dragonfly on a rod inserted into the post opening.
  • the dowel is pivoted in the manner of a self-aligning bearing against the inner wall of the ceiling circular cutout and so vertically aligned.
  • the dowel can also be rotated within the guide formed by the ceiling circular cutout, if rectangular piles are to be fastened with a preferred direction - for example, in traffic signs.
  • a circular cutout of defined size is made in the ceiling of the fixed floor, the is only slightly larger than the diameter of the dowel flange, the inner wall of the circular cutout can act as a fulcrum in aligning the bottom tube introduced into a well dug below the circular cutout and prevent sinking of the flange in the moist hardenable material.
  • the floor pipe may be extended prior to insertion into the hoistway by at least one extension pipe having a bottom pipe earth end receiving opening and an extension pipe earth end is dug deeper according to the geometry of the extended bottom tube, wherein the shaft (51) is dug longer correspondingly longer than the extended bottom tube (2, 20).
  • only a basic dowel of predetermined length needs to be made, which can be modularly extended by attachable extension tubes.
  • the bottom tube (2) and / or the extension tube e (20) retaining means which make it difficult to move, twisting and pulling the ground anchor (1) against the soft material and prevent hardened material.
  • posts After setting in / pouring in the ground anchor, posts can be fixed in the anchor.
  • a post mounting with: a clamping ring (11) for the post and on the clamping ring (11) against the mounting flange (7) unscrewed clamping plate (8) with post opening and clamping screw holes (22); Inserting a post end through the clamping ring (11) and the clamping plate post opening (10) in the bottom tube opening, Tightening the clamping screws (9) against the screw sleeves in the mounting flange (7) under compression of the clamping ring (12) under adhesion to the post (30) instead.
  • This tensioner allows easy replacement of the posts and is robust to rear-end collisions - i. only the clamping device is deformed - the anchor remains unharmed.
  • a cover plate with screw holes (24) can be screwed onto the flange (7) while covering the post opening, if presently. no post is included in the dowel.
  • a particular advantage of the invention is that now the introduction of the posts is repeatable and automatable possible.
  • normative conditions of the post attachment can be created, as they are, for example, desired for participating in the road posts (eg traffic signs) or for uniform design of street furniture.
  • the bottom tube earth termination end is integral with the tube (2) and has a streamlined taper which is closed by forming into a round closed end or bent, cut unshaped bottom tube sections, or by a separate, end-capped, streamlined cap (40) is formed.
  • the at least one bottom pipe (2) and / or the extension pipe (20) can have flow-favorable anchoring elevations.
  • ground anchors are placed under the least possible burden on the environment by a repeatable approach and easily adaptable to changing, to be absorbed by them post and similar rod-shaped objects or loads to be absorbed without consuming to store.
  • floor pipes of a ground anchor can be provided with extension pipes of different lengths and possibly interchangeable tails, it is possible to provide a ground dowel system that can be easily adapted to local conditions and soil conditions.
  • extension tube at the ground end with a protruding anchoring bead for improved anchoring.
  • shaft 51 can be extended conically downward during its excavation, so that even the cured viscous material itself forms a second anchoring bead or cone and the overall system receives a high pull-out strength.
  • Possible materials for the system are corrosion-resistant, elastic materials, i.a. Steel, cast iron, sintered metal, aluminum, brass and high-strength plastics.
  • the shaft can be easily produced, as well as the cast-in anchors may also be easily removed together with the concrete from the ground - for example by means of a corresponding Drill bit or cup chisel.
  • An alignment of the ground dowel against the inner wall of the ceiling circular cut is possible in wet concrete effortlessly and with little effort - both in terms of height, as well as the direction and orientation of the anchor, if rectangular profiles are to be used.
  • Fig. 1 For example, there is schematically illustrated a method of aligning a ground anchor in a fixed ground. It is first made a circular cut from the ceiling 52 of a paved surface by means of a drill bit. In the next step, a slot 51 is dug under the circular cutout of approximately the same diameter as the circular cutout and approximately the length of the ground anchor. In the shaft then curable material - in this case, liquid concrete - filled. It is important to ensure that as much concrete is filled as it corresponds to the shaft volume minus the anchor volume. In this soft concrete Now a ground dowel 1 is pressed until its mounting flange 7 is in the ceiling 52.
  • bottom tube 2 displaces the concrete in the shaft, which flows upwards in the shaft, fills the shaft 51 up to the ceiling 52 and optionally swells out somewhat over the ceiling.
  • the concrete also flows around projections on the bottom tube 2, prevent the hardening of the concrete extraction and / or rotation of the bottom tube 2 and the bottom anchor 1.
  • An excess amount of concrete can be removed or leak through any existing discharge openings 26 in the cup-like mounting flange 7 and removed there.
  • the ground dowel 1 thus introduced into the moist concrete is now aligned perpendicularly in the shaft - for example by means of a known, in the bottom tube pluggable alignment with a circular level or spirit level (not shown).
  • a circular level or spirit level not shown.
  • the tough flowing concrete stabilizes the new position of the ground anchor 1 and is strengthened by the curing.
  • 7 functional parts on the ground dowel flange such as a clamping device or a cover 60.
  • the tensioning device has a clamping and reinforcing ring 13 which is shown as a symmetrical part. In the front, a clamping slot 12 is visible. Above the clamping ring 13 is the clamping plate 8, which has approximately the same outer diameter as the flange 7.
  • the clamping plate 8 is slightly angled in this embodiment for stiffening. It has countersunk holes for screws, so that after screwing in the screws, a flat surface is created. Above this is the rod-shaped object 4, which is to be fastened.
  • the clamping plate 8 is fixed with four screws 11 on the flange 7. In this case, the clamping ring 13 is activated and clamps the rod-shaped object.
  • Fig. 2 shows a ground anchor for use in the process of the invention in an exploded view with flange and clamping plate lot and an extension tube with a tip.
  • the clamping and reinforcing ring 13 is formed as a symmetrical double cone and is mounted in a conical shape of the flange inner opening.
  • the expanded bottom tube 2 and the clamping and reinforcing ring 13 form in the uppermost region of the flange 7, ie where the greatest bending forces occur, a stable stiffening. This stiffening transfers to the area of Clamping plate 8, the passage only a few millimeters from the surface of the mounting flange 7, whereby the lever arm when bending the rod-shaped article 4 is kept as small as possible.
  • the clamping plate 8 is stiffened by a bend and has the complete bottom cover and maximum stability the diameter of the outer contour of the flange 7. It clearly shows how the ending in a rounded tip ground anchor 1 in a widened in the upper region extension tube 20, in this embodiment also has a rounded tip produced by forming, can be introduced and thus extends the bottom tube 2.
  • Fig. 3 shows a detail of the device for fixing rod-shaped objects 4 after Fig. 1 in the closed state on average.
  • the biconical clamping and reinforcing ring 11 is approximately flush with the top of the clamping plate 8.
  • the recessed screws 9 are as in Fig. 2 tightened so that the angled clamping plate 8 is seated on the flange, the clamping plate 8 receives a bias in itself by the tightened screw.
  • Fig. 4 is shown a further embodiment of extension tubes - here with a separately formed streamlined cap 40 with a circumferential Anank ceremoniesswulst 42, which can be screwed onto the extension tube.
  • Fig. 5 shows an extension tube with attached cap 40, wherein the connection to the extension tube should not be limited to screwing - it can be attached in any other way - eg. By welding, soldering, press fit.
  • Fig. 5a 1 schematically shows the manufacture of an extension tube with molded cap 40, wherein a round closed end of the extension tube is made by cutting triangular cutouts and then forming by pressing the cut extension tube end against a mold.
  • Fig. 6 represents another part of the ground dowel system 1 according to the invention, the cover plate 60.
  • the embodiment of a cover plate 60 shown here by way of example is for secure covering of the ground dowel opening when the ground dowel 1 is not required for post 4, provided. It is slightly curved and has in this embodiment elevations on the surface that prevent slipping on the cover plate 60. Their holes with recesses allow the screwing of countersunk screws, which avoids stumbling over the dowel covered in this way and a visually appealing impression of the area equipped with the ground dowel with cover surface is achieved.
  • ground anchor system of the invention and the method of anchoring ground anchors a secure, detachable and well-aligned post anchoring device can be made.
  • Fig. 7 - 16 steps of an embodiment of the method according to the invention with a pre-drilling and excavation template.
  • a circular cutout in a ceiling 52 is produced with a punching bell 53 ( Figure 7 ) whose diameter is slightly larger than the pot diameter of a cup-like mounting flange 7 on the dowel 1 after the FIGS. 1 to 3 is - as in Fig. 7 shown.
  • excavation 56 and pre-hole templates are placed in the ceiling opening, in which embodiment the pre-hole template 54 removably rests on the excavation template 56.
  • Vorlochschablone 54 Through the Vorlochschablone 54 is centered by means of a Vorlochrohrs 55 punched a pre-hole in the ground, which transported in Vorlochrohr 55 travels up and removes ground, as in Fig. 9 indicated.
  • This pre-hole is subsequently extended with a suitable tool through the Aushubschablone 56 to about 1.5 times to double the diameter of the anchor 1 so for example.
  • rods or hand excavators With flat chisel, rods or hand excavators and by hand depending on the equipment and quality of the ground ( Fig. 10 ).
