Definitions

  • the present invention relates to a device for exposing the reinforcing bars of concrete piles, with a supporting device in the form of a box-shaped frame with a central passage for the pile to be processed and crushing tools arranged on the supporting device in the region of the central passage, each crushing tool using a piston cylinder -Aggregates is driven, wherein means are available to selectively supply a pressure fluid to the aggregate, the crushing tools being arranged on all sides distributed over the circumference of the central passage.
  • the piston-cylinder units are arranged horizontally, ie in the working position of the device. Each unit is equipped with a piston with a penetration tip. If the piston is pressurized by a pressure fluid, it penetrates into the respective concrete pile in order to burst open the concrete to expose the reinforcing iron. Accordingly, the piston-cylinder units must each be arranged in such a way that the tips mentioned penetrate into a pile to be machined in areas between the respective reinforcing bars, otherwise the reinforcing bars are damaged.
  • the circuit of the pressure fluid of the known device is such that the pistons were extended independently of one another, so that the device could not necessarily center around the concrete pile, so that the penetration points of the tips were not always between respective ones Reinforcing irons were produced, which in turn led to the risk of damage to reinforcing irons.
  • the aim of the invention is to remedy the disadvantages mentioned above.
  • the device according to the invention is characterized by the features of claim 1.
  • each breaking tool is designed as a rocker-shaped chisel with a cutting edge, which is at the end opposite the respective cutting edge on the piston Cylinder unit is articulated and is pivotally mounted in the frame at a point located between this articulation point and the cutting edge in the frame about an axis of rotation which runs at least approximately parallel to the longitudinal central axis of the frame.
  • the chisels and their piston-cylinder units can be pivoted in one plane (usually horizontal plane) at right angles to the longitudinal center axis of the frame and thus to the concrete pile.
  • reference numeral 3 denotes a box-shaped frame, which is, for example, a welded steel structure.
  • the longitudinal central axis of this frame 3 is designated by the reference number 11.
  • the frame 3 has a central passage 4 for a concrete post 2 to be processed, which is shown in dot-dash lines and has the greatest possible thickness in FIG. 1, but has a smaller thickness in FIG. 2 in another example.
  • the frame 3 has a square passage 4, see also FIG. 2.
  • the right-hand side of FIG. 1 shows the rest position and the left-hand side shows the working position of the unit 6.
  • the piston-cylinder unit 6 is articulated at the end 9 of a breaking tool 5.
  • This breaking tool 5 is a two-armed, rocker-shaped Chisel formed and has two cutting edges 7, 8 ( Figure 2).
  • the chisel 5 is mounted in the frame 3 at a point 10 located between its two ends.
  • the axis of rotation 14 of the rocker-shaped breaking tool 5 located at the point 10 extends at least approximately at right angles to the longitudinal central axis 11 of the frame 3.
  • the chisel 5 has the two lever arms 19 and 20 with respect to the point 10, ie with respect to the axis of rotation 14.
  • the lever arm 19 is longer as the lever arm 20.
  • the cutting edges 7, 8 of a chisel 5 lie at least approximately parallel to the axis of rotation 14 of this chisel 5.
  • the assembly 6 is articulated at the point 13 on the frame 3.
  • This point 13 is higher than the axis of rotation 14.
  • the piston-cylinder unit 6 is now arranged in such a way that its longitudinal center axis 12 is inclined to the longitudinal center axis 11 of the frame 3 and no longer runs at right angles thereto. This results in a considerable saving of space in the horizontal direction and, furthermore, each piston-cylinder unit 6 can be dimensioned so large that it can also exert the necessary high compressive force because the height of the frame 3 is practically no narrow limits.
  • each chisel 5 is fork-shaped and has two cutting edges 7, 8. This form of training allows a safe penetration into the concrete without destroying the reinforcement 1.
  • the supply of the hydraulic fluid to the four piston-cylinder units 6 contains a liquid quantity regulator 22, which ensures that the same quantity of hydraulic fluid is supplied to each piston-cylinder unit 6.
  • a liquid quantity regulator 22 ensures that the same quantity of hydraulic fluid is supplied to each piston-cylinder unit 6.
  • the breaking tool 5 is designed as a fork-shaped chisel and thus has two cutting edges 7, 8, which allows the chisel to penetrate deep into the concrete without damaging the reinforcement 1.
  • the width of the chisel 5 or of the cutting edges 7, 8 can be selected completely independently of the size of the piston-cylinder unit 6, with which a respective adaptation to predetermined distances between the reinforcing bars 1 can be carried out without further ado.
  • the controller for the hydraulic quantity ensures that all four units 6 and thus all crushing tools 5 each carry out the same stroke, so that automatic centering and no lateral displacement of the device relative to the pile 2 takes place.
  • FIGS 3 and 4 now show something in one on a larger scale, a chisel-shaped breaking tool 5, which is equipped with crushing members 15, 16.
  • the shattering members 15, 16 are plates arranged on the top of the breaking tool 5 and projecting therefrom, each with a cutting edge 17.
  • the cutting edge 17 runs parallel to the plane of the plate 15 or 16.
  • the plates with their cutting edges 17 are from the respective cutting edges 7, 8 arranged set back.
  • the cutting edges 17 run inclined to the upper side 18 of the breaking tool 5 and thus also inclined to the vertical 21.
  • the angle ⁇ is in the range from 0 to 30 °.
  • the vertical 21 is perpendicular to the top 18.
  • the cutting edge 17 runs, as can be seen from FIG. 3, inclined to the upper side 18.
  • the two end positions of the breaking tool 5 are shown in FIG. 1, and it is obvious that when the chisel-shaped breaking tool 5 is pivoted in, the cutting edges 17 of the shattering members 15, 16 at a changing angle on the part to be machined Apply pile section.
  • the force vectors due to the contact pressure of the shattering members 15, 16 must now prevail in the part of the pile sheave to be shattered, on the basis of which the pile sheave actually breaks. It has been found that the best result is achieved if the cutting edge 17 is inclined with respect to the vertical 21 at an angle in the range from 0 to 30 °. This is an angle in the range from 90 to 60 ° with respect to the side 18.
  • the angle ⁇ is chosen to be larger, ie the edge 17 has a relatively weak inclination with respect to the side 18, the vertically directed force vectors would predominate in the section of the pile to be separated, so that the pile washer would only be raised and not broken.
