Definitions

  • the invention relates to a leveling and pulling device according to the preamble of claim 1.
  • the device is used both for leveling or leveling surfaces made of solid bodies, for example laths, and for removing or smoothing surfaces made of granules such as gravel or sand or malleable masses such as concrete or mortar.
  • material is used for the granulates and masses mentioned.
  • two boards or strips are used for screeding in a very simple way, which, standing on one of their long edges, are placed parallel to each other at a certain distance on the surface and their upper edges serve as rails for guiding a screed board, with which the between The material present on the rails is leveled on its surface.
  • This known pulling device has the particular disadvantage that after it has been removed, long recesses remain in the material that reach down to the substrate.
  • a pulling device in which a tubular frame has longitudinal bars resting on stands, which serve as rails for a skimming board. Since the skimming board is pulled over the upper edge of the longitudinal bars, impressions from the longitudinal bars remain in the material even with this device after it has been removed.
  • the document DE2912906A1 discloses a similar device in which two slide rails are supported on uprights. A screed is arranged between the running rails and is equipped with rollers that roll on the top of the running rails. Areas to the side outside the running rails cannot be peeled off with this device.
  • the invention is based on the object of proposing a pulling device which overcomes the disadvantages of the known devices.
  • the device can also be used to pull off areas that are laterally outside the guide rails.
  • Figure 1 shows in a perspective representation an overall view of a first embodiment of the pulling device according to the invention.
  • the device contains two Guide rails 1, which are arranged parallel to one another in the figure, but this is not essential for the function of the device.
  • Each guide rail 1 rests on two supports 2, which support the guide rail 1 at a distance above the ground.
  • the two guide rails 1 are connected to one another by two spacers 3, which are arranged parallel to one another in the figure, but this is not absolutely necessary for the device to function.
  • a peeling rail 4 At a distance below the guide rails 1 and approximately at right angles to them is a peeling rail 4 with the help of two in Figure 1 Suspensions 5, which are not visible, are connected to the guide rails 1.
  • two optional wings 6 protruding at right angles are shown on the peeling bar 4, which can support the distribution of the material to be peeled off, especially in the edge area of the surface to be peeled off.
  • the wings 6 can also be used to attach a hand planing or milling machine, for example to level the battens.
  • the peeling bar 4 protrudes laterally clearly beyond the guide rails 1, so that material can also be withdrawn from the side of the guide rails 1.
  • the supports 2 are each arranged on the outer side of the guide rails 1.
  • the puller bar 4 can first be moved on one side past a support 2 by being shifted sideways until one of its ends can be moved past the relevant support 2.
  • the other end of the pull-off rail 4 is then moved in opposite directions. As a result, areas that lie in front of or behind the supports 2 in the direction of the guide rails 1 can also be removed.
  • Figure 2 shows an excerpt from Figure 1 in the area of the suspension 5 on an enlarged scale.
  • the double arrows 8 to 10 indicate how the peeling bar 4 is movable with respect to the guide rails 1, namely displaceable in the direction of the guide rails 1 (double arrow 8), whereby the peeling bar 4 is not necessarily moved parallel to itself, but along the left and right guide rail 1 is displaceable by different amounts.
  • the pull-off rail 4 can also be displaced at right angles to the guide rails 1 (double arrow 9) and pivoted upward (double arrow 10).
  • the material to be smoothed can be optimally distributed, in particular at the beginning of the smoothing process.
  • the purpose of the holes 7 in the Guide rails is discussed below in connection with the Figures 4 and 5 explained.
  • Figure 3 shows in one orientation accordingly Figure 2 on a further enlarged scale, the suspension 5 without guide rail and pull-off rail.
  • a first pair of rollers 11 which according to the first embodiment according to the Figures 1 to 6 inside the in Figure 6 shown profile of the guide rail 1 is received, arranged and allows the translational displacement of the peeling rail 4 along the guide rails 1 according to the double arrow 8 in Figure 2 .
  • the second pair of rollers 14 can be rotated relative to the first pair of rollers 11 about a vertical axis 17, so that the angular position of the puller rail 4 with respect to the guide rails 1 can deviate from the right angle.
  • the second pair of rollers 14 can be pivoted about a horizontal axis 18 in order to facilitate the initial coarse distribution of the material to be smoothed.
  • a latching device 19 can be provided for this purpose.
  • a support roller 12 is visible, which is intended to support the suspension 5 within the profile of the guide rail 1, namely on an intermediate wall 31 ( Figure 6 ), to be supported.
  • the axis of the support roller 12 is guided in an elongated hole 13 so that its position can be adjusted such that the pair of rollers 11 is guided in the profile of the guide rail 1 without play, but can also evade if a small foreign body gets into the profile.
  • the support roller 12 is advantageously biased by a spring (not shown).
  • the axis of the support roller 15 is guided in an elongated hole 16 so that its position can be adjusted in such a way that the pair of rollers 14 is guided without play in the profile of the puller bar 4.
  • the support roller 15 is also advantageously biased by a spring (not shown).
  • a support 2 on a section of a guide rail 1 is shown in perspective.
  • a connection part 20 is detachably connected to the guide rail 1 by means of a screw connection 21 which penetrates the previously mentioned holes 7.
  • the "leg" of the support is designed in the example as a threaded spindle 22, which is axially in the connection part 20 guided, rotatable spindle nut 23 is added.
  • connection between the threaded spindle 22 and the spindle nut 23 can be disengaged, for example as in the document, in an embodiment not shown CH420572A described.
  • a tip 24 arranged at the lower end of the threaded spindle 22 is preferably equipped with a conical thread, as is common, for example, with wood screws.
  • the tip 24 can be screwed into the ground, for example a formwork.
  • a foot or a mounting bracket can also be provided with which the device is anchored, for example, on a beam.
  • the upper end of the threaded spindle 22 in the figure can be provided with a slot, internal or external hexagon or similar coupling means for engaging a tool for screwing in the tip 24.
  • connection point between one of the guide rails 1 and a spacer 3 is shown in perspective.
  • a connection part 25 is detachably connected to the guide rail 1 by means of a screw connection 21 which penetrates the previously mentioned holes 7.
  • a support plate 26 serves to support the spacer 3 and has a screw connection 27 with which the spacer 3 is fixable.
  • An elongated hole 29 in the spacer 3 allows precise alignment.
  • Figure 6 shows, in perspective, a section of a profile from which the guide rails 1 and / or the pull-off rail 4 can be made.
  • the profile preferably has at least one partition 31 which separates a cavity 30, as well as a continuous longitudinal slot 32 on the lower side in the figure 32 at the top of the profile. In this embodiment, they are rollers 11, 14 of the suspension 5 received in the cavity 30 of the profile.
  • Figure 7 shows an alternative embodiment of the profile from which the guide rails 1 and / or the puller rail 4 can be made.
  • Holding parts 33 which carry two guide tubes 34, are attached to the outside of the profile at intervals.
  • the rollers 11, 14 of the suspension 5 must be arranged in pairs at a vertical distance so that they accommodate the guide tubes 34 between them.
  • the guide rails 1 do not necessarily have to be aligned parallel to one another and the spacers 3 do not have to be oriented parallel to one another and at right angles to the guide rails 1. It is only important that the supports 2 are oriented more or less perpendicular to the base, which can be easily adjusted by means of the elongated holes 28, 29 described.
  • the device can not only be used for leveling and leveling horizontal surfaces, but can also be used on inclined surfaces, vertical surfaces, for example walls, and also overhead, for example for smoothing or sliding ceilings.
  • the device can easily be dismantled into its individual parts and stored and transported in a space-saving manner.
