Definitions

  • the invention relates to a device for the central insertion of a sheeting support into an earth borehole.
  • the beams or shoring supports of the screed walls are inserted into previously drilled holes. These boreholes can be 10m deep.
  • Beam screed walls were previously mainly characterized by the fact that the screed walls themselves had to be cut to size on site because it is usually extremely difficult to arrange the column spacing so precisely that prefabricated shoring walls could also be used. So far, one was essentially dependent on wood as a building material for the shoring walls, which in turn required a corresponding number of supports, which made the shoring very expensive. Attempts have been made, e.g. Reinforced concrete slabs can be used in U-shaped cross-sections, but these types of shoring could not prevail because they still required wedging of the shoring walls on the supports and correspondingly large spacing tolerances or appropriately large flanges of the shoring. This meant that these types of installation were still too cost-intensive and, since wedging had to be done by hand, was not safe enough because the personnel had to work in the unprotected construction pit.
  • the present invention has for its object to provide a possibility, known from the channel shoring shoring elements, namely shoring supports with essentially form-fitting guides for shoring panels guided therein not only in the channel shoring, but also in large construction pits as a one-sided support, in particular also as a reusable support to be able to use.
  • This device is clamped to the lower end of a shoring support and lowered together with it into the earth borehole. As soon as the support sits on the bottom of the borehole, the centering pistons of the device are extended, which are supported on the circumference of the borehole and center the lower end of the shoring.
  • suitable alignment devices e.g. B. laser devices
  • the shoring support is fixed vertically and then e.g. in a mortar, foundation concrete or the like placed on the borehole.
  • suitable measures e.g. Severing the column base or the like, which is not the subject of the invention here.
  • the device according to the invention has the advantage that it is now possible to use supports in the screed shoring in which prefabricated shoring panels can be inserted in a form-fitting manner, ie in which the shoring panels are fixed both perpendicular to their surface and in the direction of their longitudinal extent. This eliminates the wage, labor and risk of wedging the shoring panels in the unprotected excavation pit. It is also possible to work with larger column spacings, and thus with fewer shoring columns and bores in the ground, which on the one hand ensures further economy and faster installation. Furthermore, the shoring material can also be used several times with low personnel expenditure, whereas it has been common up to now the case was that the lining material remained in the ground.
  • the device according to the invention consists of an annular support housing 1, the outer diameter of which is slightly smaller than the diameter of an earth borehole at the construction site. However, the inner diameter of the support housing 1 is larger than the cross section of a shoring support 2 to be inserted into an earth borehole. In the support housing 1 there is an annular insert base 3, the inside diameter of which is also larger than the cross section of a shoring support 2.
  • a fixed stop 8 which is adjustable in elongated holes 7 and which can engage on one side of the installation support 2 to be inserted.
  • the fixed stop diametrically opposite is a pressure-actuated tensioning piston 9 which is guided in a cylinder 10 fastened to the insert base 3 and on on the other side the shoring can attack.
  • the fixed stop 8 and the tensioning piston 9 together form a clamping device.
  • Below the insert base 3 there are also control blocks 11 for the pressure medium supply line to the one.
  • centering pistons 13 On the underside of the insert base 3 there are furthermore radially aligned lifting cylinders 12 with centering pistons 13, which can be moved outwards through openings 14 in the wall of the support housing and are essentially designed like the centering pistons 5. These centering pistons 13 are used for rough centering, the centering pistons 5 on the top of the insert base 3 for fine or subsequent centering.
  • the support housing 1 has on its upper side support eyes 15, into which the holding cables 16 engage.
  • the necessary electrical power lines 17 and the pressure medium lines 18, 19 intended for the forward and return flow of the pressure medium cylinders also go up.
  • the device 22 according to the invention is first placed on approximately 50 cm high wooden blocks or the like.
  • the centering pistons 5 and 13 are retracted so that the outer surface of the support housing 1 is smooth.
  • the tethers 16 are laid out laterally.
  • a shoring support 2 is threaded vertically from above into the clear space between the fixed stop 8 and the tensioning piston 9 and placed on the floor. Now the cylinder 10 is actuated so that the shoring support 2 is firmly clamped.
  • the shoring support 2 with the device 22 clamped thereon is introduced into the earth borehole 20 (Eig.5) and lowered to the foundation filling 21.
  • the tethers 16 are tracked by hand.
  • the centering pistons 13 are first moved outwards against the wall of the borehole 20 for rough centering. Subsequently, fine centering is carried out by means of the centering piston 5 with the aid of a spirit level or a laser device. If the sheeting support 2 has reached its predetermined position, the clamping connection between the clamping device 8, 9 and the sheeting support 2 is released. The support column 2 can then in the. Foundation filling 21 are drained and takes a precisely centered position in the earth borehole 20. The shoring support 2 is then released from the hoist 23.
