Definitions

  • the present invention relates to a machine for cutting building materials by means of a cable or abrasive wire forming a closed loop driven in circulation and in traction by the movement of a driving pulley around which circulates the cable or the abrasive wire and which is mounted on a mobile carriage moving along an elongated frame by means of a linear drive device.
  • the cutting, for a total or partial demolition, of the materials of a building or a work poses more and more problems, especially in reinforced concrete constructions of great thickness where the use of diamond discs of large diameters poses many problems with training, dimensions and noise.
  • Machines are also known using an abrasive helical wire, more recently a diamond cable, driven in circulation by a drive device with several pulleys mounted on a tractor means moving on rails placed on the ground, as and when cutting progress (EP-A-0 078 920).
  • the pulleys are simple pulleys and the length of the cables is chosen according to the size of the cut.
  • diamond cables which are more efficient but more expensive
  • the reduction in the length of the loop is obtained by cutting and joining the ends by means of screwing or crimping. Given the size of such facilities, they are used almost exclusively in the operation of open pits where there are few or no space limitations for move the tractor device. In addition, this tractor device cannot move in all directions, in particular vertically.
  • the purpose of the present invention is to allow construction materials to be cut by means of an abrasive wire or cable, without limitation and in all positions, thicknesses less than or greater than 60 cm, in a limited space allowing in particular its use for inside standard constructions.
  • the machine must therefore have a small footprint and a reduced weight.
  • This machine can be used in all positions, especially in vertical, horizontal or oblique position.
  • the cable slack winding system using two grooved pulleys allows the same fixed length of cable or abrasive wire to be used from start to finish.
  • Figure 1 is a perspective view of the machine in horizontal use.
  • FIGS 2 to 5 schematically illustrate four successive working phases of the machine.
  • the machine shown in Figure 1 comprises an elongated rigid frame 1 of aluminum provided with a base plate and support 2 perpendicular to the axis of the frame.
  • This frame carries a carriage 3 which can move in two slides 4 and 5 of the frame. These slides, having a U-shaped profile, could also serve as rolling tracks for a carriage 3 provided with rollers. In all cases the carriage is retained in all directions transverse to the frame, so that the frame can be used in any position.
  • the carriage 3 is attached the ends of a chain 6, a single strand of which is visible in FIG. 1, a chain driven by a motor 7 fixed on the base plate 2 and passing over a return 8 mounted at the other end of the built.
  • the carriage 3 carries a drive pulley 9 provided with several grooves and driven by a hydraulic or electric motor. On the carriage 3 is also mounted a crazy grooved pulley 11 between the driving pulley 9 and the base plate 2. Instead of a single grooved pulley it is of course possible to use several pulleys with a single groove, this both for the pulley 9 as for the pulley 11.
  • an abrasive cable 12 for example a diamond cable.
  • FIGS. 2 to 5 It is desired to cut a section 13 from a concrete wall.
  • the installation of the machine consists in applying its base plate 2 against the wall and in anchoring this plate by expanding plugs using the holes 14 provided therein for this purpose.
  • Figure 2 can be both a plan view and an elevational view. Holes 15 and 16 are drilled in the wall to be cut through which the cable 12 is first opened. Then connect the ends of the cable 12 so as to form a closed loop which is passed once around the pulleys 9 and 11 of the carriage 3. If the section 13 to be cut is smaller we will wind the cable 12 once again around the pulleys 9 and 11. The cable 12 is tensioned by means of the drive chain 6 of the carriage.
  • the motor 10 is started, which has the effect of driving the cable 12 in circulation and of initiating the section 13 to be cut.
  • the cable 12 is kept taut by simultaneously advancing the carriage 3 towards the end of the frame 1, in the direction of the arrow, by means of the motor 7.
  • the motor 10 is stopped and the carriage (3) is brought back to the base plate 2.
  • the cable slack 12a is wound up around the pulleys 9 and 11 so as to form a taut outer loop ( Figure 4). Then repeat the operations according to Figure 2 to cut out the rest of section 13 ( Figure 5).
