Definitions

  • the present invention is concerned with a method for the casting of concrete products by means of continuous slide-casting in which the concrete mix is compacted by displacing one or several walls of the slide-casting mould structure.
  • the invention is also concerned with a device for the casting of concrete products by means of continuous slide-casting, wherein the device includes longitudinal walls as well as, inside the said walls, one or several forming members that form cavities.
  • An aim of the present invention is to provide a casting method in which the compacting takes place at the same time both efficiently and free of noise. At the same time, the quality of the face of the product is improved as compared with the products manufactured by means of the prior-art technique.
  • a method of casting a concrete product by means of continuous slide-casting is one in which the concrete mix is subjected to pressure by means of a spiral screw means, the concrete mix is compacted by forcible displacement of one or more longitudinal walls and one or more cavities are formed in the product by means of one or more forming members provided between the walls with a top wall of the longitudinal walls being positioned above the one or more forming members; in which each forming member is moved to alter the angle of its longitudinal axis in relation to a predetermined articulation point; and in which the concrete mix is compacted by the top wall being repeatedly forcibly displaced along the same predetermined path of movement.
  • a device for the casting of aconcrete product by means of continuous slide-casting comprises a plurality of longitudinal walls including a top wall, means for forcibly displacing at least one of the walls to compact the concrete mix, spiral screw means for feeding the concrete mix, and one or more forming members, provided between the walls, for forming cavities in the concrete product, with the top wall being positioned above the forming members; in which each forming member is movable to alter the angle of its longitudinal axis in relation to a predetermined articulation point; and in which the displacement means is arranged to drive the top wall repeatedly along the same predetermined path of movement.
  • the amplitude of the displacement of the top wall is remarkably high, being reduced to zero at the trailing end. In other words, the movement becomes smaller towards the trailing end of the top wall, which acts as a compacting mechanism. If required, a so-called levelling board follows after the compacting board.
  • the machine is provided with one or several spiral screws 2, which are in such a way conical that they become larger towards the final end of the machine.
  • a cavity mandrel 3 is fitted, which is, if required, followed by a follower tube 4.
  • the rear end of the cavity mandrel 3 is fixed, e.g., by means of a ball joint or equivalent mode of fastening which permits a change in the angle of the axis, and the forward end of the mandrel performs an eccentric movement relative the longitudinal axis and compacts the mix around the cavity.
  • the device is provided with a compacting board 5 and side boards 6. Behind the compacting board 5, there is a levelling board 8.
  • the machine moves on a base 9, being supported on wheels 10, in the direction indicated by the arrow.
  • the compacting board 5 is, by its trailing end, fixed to a horizontal transverse shaft 11.
  • the front end of the compacting board is connected to a motor 14 in a suitable way, e.g. by the intermediate of an arm 12 and an eccentric cam 13.
  • the front end of the board is displaced back and forth up and down.
  • the path of movement is illustrated as a side view in the bottom part of Fig. 2.
  • Towards the trailing end, the movement of the board is reduced to zero.
  • the movement may be synchronized with the eccentric movement of the cavity mandrel 3 so that the rising and falling of the board take place at the same time as the rising and falling of the cavity mandrel.
  • the frequency of the movement of rising and falling of the board may also differ from the frequency of the movement of the mandrel, and they may be in a suitable mutual relationship. In this way, in the portion of the slab placed above the cavities, in the mix, a shearing movement is produced, which, together with the pressure produced by the screws and with the movement of the mandrels, compacts the mix.
  • the direction of movement of the board may, however,, also be contrary to the movement of rising and falling of the mandrel.
  • a groove former 30 is connected with the board 5 by means of a lever arm 29, the said groove former 30 moving along with the board 5 up and down.
  • the final end of the groove former is linked to the side board 6 by means of a pin 31. In this way, the movement of the groove former is at the initial end at the maximum and at the final end zero.
  • This groove former promotes the compacting of the slab at the lateral areas of the slab.
  • the transverse shaft 11 at the trailing end of the board 5 is attached to an articulated arm 15, whose top end is attached to a transverse shaft 16.
  • the front end of the board 5 is displaced by means of an eccentric cam 17 along a path of movement revolving around a transverse shaft.
  • the movement of the trailing end of the board is in the vertical direction zero, but in the horizontal direction the length of the path of movement corresponds to the stroke length provided by the eccentric cam when the articulated arm 15 swings around the shaft 16.
  • the path of movement of the board is illustrated as a side view in the bottom part of Fig. 4.
  • the trailing end of the board 5 is attached to a vertical shaft 18 by means of a ball joint 21 or equivalent.
  • the front end of the board 5 is attached to an eccentric cam 20 by the intermediate of a transverse arm 19, the said eccentric cam 20 providing a horizontal transverse movement back and forth for the front end of the board.
  • the movement is zero at the ball joint 21, but at the sides of the board mainly movement in the longitudinal direction of the slab.
  • the direction of movement of the front end of the board 5 is contrary to the lateral movement of the mandrel 3, but the direction may also be the same.
  • the path of movement of the board is illustrated as viewed from the top in the bottom part of Fig. 6.
  • the compacting plane 5 is supported by means of two vertical shafts 22. At the lower end of each shaft 22, there is an eccentric cam 23, which brings the plane 5 into a horizontal grinding movement.
  • the path of movement is illustrated as a top view in the bottom part of Fig. 10.
  • the lateral component of the movement of the board may be either of opposite direction or of the same direction compared with the horizontal component of the movement of the front end of the mandrels 3.
  • one or, side by side, several eccentric cams 24 synchronized with each other are connected with the front end of the compacting plane 5, which said eccentric cams 24 revolve eccentrically relative the longitudinal axis 25.
  • the front end of the board 5 receives a rotary movement so that it rises and falls and moves to both sides. In other words, the movement takes place in a vertical transverse plane.
  • the trailing end of the board 5 is supported at the middle preferably, e.g., by means of a ball joint 21 so that the movement of the plane 5 at the joint is zero but, at the trailing end at the sides of the board, longitudinal movement.
  • the movement of the board 5 may be synchronized and either of the same direction or of opposite direction relative the movement of the mandrels 3.
  • the compacting board unit 5 consists, e.g., of three subsequent transverse beams 5', which are attached to two or more longitudinal binder beams 27 by means of articulated joints 26. At their trailing ends, the binder beams are attached to vertical shafts 28. By means of an arm 19 and an eccentric cam 20, the system of beams is brought into a transverse horizontal movement, which is reduced towards the trailing end. The movement may be synchronized and either of opposite direction or of the same direction relative the horizontal component of the movement of the mandrels 3.
  • the movement of the compacting board 5 may be synchronized with the movement of the mandrels 3, being either of the same direction or of opposite direction.
  • the movements may also have a certain other phase angle.
  • the frequency of the movement of the compacting board 5 may also differ from the frequency of the movement of the mandrels 3. This is accomplished by selecting the speeds of rotation of the eccentric cams appropriately.
  • the movement of the mandrels 3 may also be a movement taking place relative a vertical or horizontal shaft placed at the trailing end.
  • the groove formers 30 may also be used in the devices of the other embodiments, besides that shown in Figures 2 and 3.
