Definitions

  • the invention relates to a drill stand for a drill, referred to in the preamble of claim 1. Art.
  • a drill stand z As for a portable drill, such as a drill stand for a core drill, has a foot part with a slot for fixing the drill stand to a substrate and a column attachment means for arranging and guiding the drill on. Through the slot in the foot part, for example, a chemically or mechanically anchored or anchored in the ground fastener is passed and the foot part clamped to this, so that the drill stand is releasably fixed to the ground. Subsequently, the desired hole is created with the drill. After completion of the drilling operation of the drill stand is released from the fastener and redefined for another hole to be created on a new, previously anchored in the ground fastener.
  • a foot part for a drill stand with a slot is known, which is fixed with a dowel pin as a fastener on the ground.
  • the foot part can be moved relative to the passed and fixed in the ground dowel pin along the extension of the slot and turned off about the axis of the dowel pin, which z. B. even with an inaccurately arranged attachment point allows within the existing positioning accuracy positioning of the drill stand or the drill.

  • a mounting part for fixing the foot part is at least partially arranged in the oblong hole of the foot part.
  • the mounting part has at least one opening for the passage of a fastening means for fixing the mounting part to the ground.
  • the foot part is displaceable to the mounting part.
  • the at least partially arranged in the slot of the foot part mounting part allows by the displaceability of the foot part to the mounting part a flexible positioning of the drill stand in a large area relative to the attachment point created by the fastening means.
  • Several, z. B. adjacent series drilling can be performed from an attachment point, which significantly reduces the amount of work to create these holes, as less assembly and disassembly work to determine the drill stand are needed.
  • In the inventive drill stand only small demands are made on the exact location of the attachment point to the location of the hole to be created, since any inaccuracies of the created attachment point can be easily compensated by the relative displacement of the foot part to the mounting part and the drill stand to the attachment point.
  • the position of the at least one opening for the passage of the fastening means in the mounting part is determined essentially by the type of arrangement of the slot in the foot part and the structural design of the mounting part. With more than one opening for the implementation of the fastener in the mounting part, the adjustability of the drill stand can be further improved or vary.
  • the foot part and the inventive drill stand as a whole are simple in construction and inexpensive to produce.
  • an attachment point for the drill stand is determined or measured on the underground to be provided with bores.
  • a hole is created in the ground.

At least the portion of the mounting part, which penetrates into the slot of the foot part, has a Clearrekkung which is tuned substantially to the corresponding, shorter extension of the elongated hole, so that the displacement and rotation of the foot part is ensured relative to the mounting part.
  • the opening in the mounting part is formed as a slot, which allows additional adjustability of the drill stand. Through the slot, the mounting part and the foot part can be moved relative to the attachment point and twisted around it.
  • the foot part and / or the mounting part are plate-shaped, so that the two parts have a low overall height and are designed to save weight.
  • the foot part and / or the mounting part are understood, in which the amount of material thickness substantially is smaller than the length and width extent or the size of the amount of the diameter.
  • the elongated hole in the foot part extends in the plane which is spanned by the surface of the foot part, from which the pillar fastening means protrudes, thus allowing easy mounting to the ground and a plurality of positions of the drill stand.
  • the mounting part has an outer contour with a circumferential step.
  • smaller dimension of the mounting part is adapted to the shorter dimension of the slot in the foot part, so that when clamping the mounting part of this section penetrates into the slot in the foot part and at least a surface portion of the mounting part in regions with a surface portion of the foot part comes into contact.
  • a small overall height of the two, mutually engaging parts can be realized.
  • the larger dimension of the mounting part can be matched to the shorter dimension of the slot in the foot part, so that the mounting part largely completely penetrates into the slot in the foot part and is absorbed by this.
  • a circumferential step is provided in the slot of the foot part.
  • the size of the depression thus created corresponds, for example, to the material thickness of the mounting part, so that the top side of the mounting part essentially coincides with the top side of the foot part and the mounting part is completely received in the oblong hole of the foot part. If the mounting part also has an encircling step on its outer contour, the thickness of the peripheral step perpendicular to the greater extent of the mounting part is chosen such that this area of the mounting part is received by the peripheral step and the section of the mounting part with the smaller dimension in the mounting part narrower part of the slot comes to rest in the foot part.
  • the mounting member is slidably disposed in the foot part via a groove / comb connection, whereby the mounting member is mounted captive in the foot part.
  • the at least one groove, z. B. a tuned to the configuration of the comb recess, for example, on the outer contour of the mounting part and the at least one comb, z. B. a projection is provided on the inner contour of the elongated hole in the foot part.
  • the at least one groove may be provided on the inner contour of the elongated hole in the foot part and the at least one comb on the outer contour of the mounting part.
