Definitions

  • the invention relates to a method for at least partly embedding a slab comprising a top side and a bottom side in a substrate containing a type of sand, with the method at least comprising: placing the bottom side of the slab against the substrate.
  • the invention further relates to an apparatus for at least partly embedding a slab comprising a top side and a bottom side in a substrate.
  • a slab is understood to mean a slab which is, for instance, manufactured from a type of stone and/or concrete.
  • the term slab also includes steel or plastic slabs. Such slabs are used in civil engineering and other construction activities. Such a slab can have a weight of some hundreds to some thousands of kilograms. The dimensions can differ from slab to slab.
  • Such a method is known per se and is often used in the preparation of a ground on or over which, for instance, a traffic route is constructed.
  • a truck in some cases a train, or another vehicle generating vibration when moving
  • the vibrations supplied to the slab when such a vehicle is being moved over or along the slab result in a compaction of the sand present between the slabs and/or under the slab near the longitudinal edges of the slab.
  • sand needs to be regularly supplied to a substrate located near a longitudinal edge or circumferential edge of the slab.
  • each vibration treatment given to the slab by means of one of the above vehicles it is assessed whether the compaction of the sand under the slab has been effected to a desired extent. This may, for instance, be done by determining whether sand should be supplied to the substrate located near the longitudinal edge of the slab to compensate for the compaction of the sand present under the slab. If, after a vibration treatment, compared to a previous vibration treatment, there is no change in the substrate located near the longitudinal edge of the slab, it is assumed that the sand present near the longitudinal edges of the slab will hardly or not compact any further. If this is the case, no sand needs to be added to the substrate located near the longitudinal edge of the slab. The slab is then embedded to the desired extent.
  • the drawback of a known method is that the time taken up by this method depends on the frequency at which one of the above-mentioned vibration-generating vehicles moves over or along the slab. It is possible that a train or a truck needs to be moved over or along the slab as many as five to ten times before the desired extent of embedding of the slab can be achieved. After each passing of one the above-mentioned vehicles, it needs to be examined whether sand needs to be added to compensate for the compaction of the sand under the slab. This requires manpower and time. In other words, the known method is a time-consuming and expensive method.
  • the invention contemplates meeting the above-mentioned problem.
  • the object of the invention is achieved by a method according to the invention which is characterized in that the method further comprises transmitting vibrations to the slab by means of a vibrator which is substantially fixated with respect to the slab.
  • the slab in the substrate By means of a method according to the invention, it is possible to embed the slab in the substrate to the desired extent within a short space of time.
  • the vibrations are simply transmitted from the vibrator substantially fixed with respect to the slab, to the slab.
  • the sand Prior to the transmission of the vibrations or during the transmission of the vibrations to the slab, the sand can be supplied to the substrate located near the longitudinal edge of the slab.
  • the time between turning on the vibrator for transmitting vibrations to the slab and turning off the vibrator can be limited to a much shorter space of time than the space of time that is needed for embedding the slab by means of the known method.
  • a slab weighing 800 to 2000 kg can be embedded to the desired extent in a substrate containing a type of sand within a space of time of tens of seconds or less.
  • the time needed for embedding corresponds to the time needed for a vibration-generating vehicle to be able to pass over or along the slab many times. Usually, this involves much more time than tens of seconds.
  • the method according to the invention offers the advantage that the embedding of the slab can be scheduled, since it only depends on the availability of the vibrator substantially fixated with respect to the slab.
  • the embedding depends on the availability of the vibration-generating vehicles for transmitting vibrations to the slab when these vehicles are moving over or along the slab. In other words, the method according to the invention is faster and less expensive.
  • DE 10105587 discloses a method for embedding paving stones. Said method comprises placing a vibrating body on a top side of the paving stones and, while providing a limitation to sideways movement of the vibrating body, glidingly moving said vibrating body over the top of the paving stones.
  • DE3324441 discloses a movable apparatus for transporting concrete parte, provided with at least one suction cup for lifting said concrete parts.
  • the vibrations from each vibrator are transmitted to a suction cup applied against the top side of the slab.
  • a suction cup applied against the top side of the slab.
  • the method further comprises maintaining a vacuum in a room bounded by the slab and the suction cup.
  • This makes it possible to move a very heavy slab. It is also possible to transmit vibrations to this very heavy slab via the suction cup. This is because, due to the vacuum created in the room, the slab and the suction cup will be sucked against each other such that, during the method, the slab and the suction cup can be considered a rigid whole. The vibrations transmitted from each vibrator to the suction cup will hardly be damped by the suction cup.
  • the suction cup may be provided with a substantially rigid plate-shaped frame having a first side and a second side located substantially opposite the first side, the first side being provided with the at least one vibrator and the second being provided with recesses for forming the room.
  • a rigid slab is eminently suitable for transmitting vibrations to the slab.
  • the at least one vibrator has been provided against the first side of the frame, so that the vibrations from each vibrator are directly transmitted to the frame.
  • the method also comprises preventing air from leaking into the room by means of a band provided on a circumferential edge of the second side of the frame, which band is substantially manufactured from a compressible material.
  • the method may also comprise determining a depth over which the slab is embedded in the substrate.
  • the determination may take place visually on the basis of a marking provided on a longitudinal edge of the slab.
  • Fig. 1 shows, in perspective, an apparatus 1 for at least partly embedding, in a substrate 2, a slab 3 manufactured from, for instance, a type of stone and/or concrete, which slab comprises a top side 4 and a bottom side 5.
  • the apparatus 1 is provided with at least one suction cup 6 which, in use, is fixatable against the top side 4 of the slab 3.
  • the suction cup 6 is provided with a vibrator 7 substantially fixated with respect to the suction cup 6 for, in use, transmitting vibrations to the slab 3 via the suction cup 6.
  • the suction cup 6 is provided with two vibrators 7.
  • the suction cup 6 is provided with means 8 for connecting a vacuum pump (not shown) by means of which, in use, a vacuum can be maintained in a room 9 bounded by the slab and suction cup 6 (see Fig. 3 and Fig. 4 ).
  • the suction cup 6 is provided with a substantially rigid plate-shaped frame 10 having a first side 11 and a second side 12 located substantially opposite the first side.
  • the first side 11 is provided with two vibrators 7 and the second side is provided with recesses 13 for forming the room 9 (see Fig. 3 and Fig. 4 ).
  • the frame 10 comprises a frame plate 14 which is provided with plates 15 on the second side 12 of the suction cup 6 for, in use, maintaining a distance between the frame plate 14 and the slab 3 manufactured from a type of stone and/or concrete when the suction cup 6 has been applied against the slab 3. As is shown in Figs. 3 and 4 , this results in the room 9 bounded by the slab and the suction cup when the suction cup has been applied against the slab 3. It could also be said that the recesses 13 on the second side 12 of the plate-shaped frame 10 are located between the plates 15 provided against the frame plate 14.
  • the frame plate 14 comprises openings 30.
  • the frame 10 designed as a suction cup is provided with an air discharge connection extending from positions in the recesses 13, through the frame, to the means 8 for connecting a vacuum pump.
  • the means 8 are designed as outlets to which vacuum lines 16 can be connected.
  • the vacuum lines 16 form an air discharge connection between the outlets and the vacuum pump not shown.
  • the outlets further have an air discharge connection through the plate-shaped frame 10 to the recesses 13, that is, in use, the rooms 9.
  • the frame plate 14 is provided with perforations for obtaining the openings 30.
  • Apparatus 1 is further provided with a band 17 provided along a circumferential edge 21 of the second side 12 of the frame 10 (see Fig. 3 and Fig. 4 ).
  • the band 17 is closed upon itself and substantially manufactured from a compressible material for, in use, preventing air from leaking into the room.
  • the compressible material preferably substantially contains rubber.
  • the band 17 is provided with a side 18 substantially facing the slab, which side comprises pores.
  • the band can be manufactured from a rubber comprising pores.
  • the band 17 closed upon itself may be provided with an inside 19 and an outside 20 which each comprise a skin which substantially seals the pores (not shown).
  • the frame comprises a U-section 22 extending along the circumferential edge 21 of the frame 10, in which U-section the band 17 is included.
  • the band 17 is provided with a band side 18 facing the slab 3 in which recesses (not shown) have been provided. These recesses allow the compressible band to deform easily and to remain connected to the surface of the slab 3 when that surface has been provided with relief.
  • the apparatus 1 is provided with two vibrators 7 substantially fixated with respect to the suction cup 6 for, in use, transmitting vibrations to the slab 3.
  • the vibrators have been provided against the first side 11 of the frame 10.
  • the vibrators 7 are electric vibrators.
  • each vibrator is provided with an eccentric (not shown) which rotates in use for the purpose of generating the vibrations.
  • the eccentrics are arranged such that, in use, they each rotate in a substantially vertically located plane. It is still more preferred that, in use, the eccentrics rotate in the same plane.
  • the eccentrics preferably rotate towards each other.
  • the fluid connection already discussed can also be described as an air discharge connection between the second side 12 of the plate-shaped frame 10 and the means 8 for connecting the vacuum pump.
  • means are included for weakening an airflow.
  • the means for weakening an airflow comprise a buffer room 23.
  • the buffer room 23 is at least partly designed as a hollow beam.
  • at least a part of this hollow beam extends parallel to the slab 3 in a longitudinal direction.
  • the hollow beam also has a strengthening function for the plate-shaped frame. This promotes the rigidity of the plate-shaped frame.
  • the hollow beams 23 are connected to one another by means of a fluid connection.
  • the air to be discharged from the rooms 9 can end up in the hollow beams 23 via the perforations in the frame plate 14 and then be exhausted therefrom via the outlets 8 connected to the hollow beams 23 by and in the direction of the vacuum pump (not shown).
  • the suction cup is provided with hoisting means 24 for placing the suction cup 6.
  • Hoisting means may be designed such that the suction cup 6 with the slab 3 fixedly sucked against it in use can also be moved.
  • the apparatus is by no means limited to the embodiment shown hereinabove.
  • the apparatus may also be provided with an assembly comprising first means which, in use, have a fixed position with respect to the suction cup 6 and second means which are designed such that, in use, these second means assume a fixed position with respect to the substrate 2.
  • This assembly may be designed to stop the transmission of vibrations to the suction cup 6 when the first and second means have reached a predetermined height relative to each other.
  • Such an assembly may, for instance, comprise a feeler and a contact point. It is also possible for the assembly to comprise a laser and a laser light detector.
  • the method for at least partly embedding a slab comprising a top side and a bottom side in a substrate containing a type of sand comprises at least placing the bottom side of the slab against the substrate and transmitting vibrations to the slab by means of a vibrator substantially fixated with respect to the slab.
  • this method is carried out using the apparatus 1.
  • the suction cup 6 is placed against the top side of the slab 3 such that a room 9 is formed.
  • the means 8 for connecting a vacuum pump will be connected to a vacuum pump. By means of the vacuum pump, air is exhausted from the room 9. This causes the top side 4 of the slab 3 and the suction cup to be sucked against each other.
  • the atmospheric pressure which is higher than the pressure of the vacuum in room 9 presses the slab and the suction cup against each other. It is then possible to place the bottom side 5 of the slab 3 against the substrate 2 by means of the hoisting means 24. Then, by means of the at least one vibrator 7 fixated with respect to the slab 3, vibrations can be transmitted to the slab 3. The vibrations from each vibrator are transmitted to the suction cup 6 applied against the top side 4 of the slab 3. The vacuum pump maintains a vacuum in the room 9 bounded by the slab 3 and the suction cup 6.
  • the suction cup 6 is provided with a rigid plate-shaped frame 10 having a first side 11 and a second side 12 located substantially opposite the first side 11.
  • the first side 11 is provided with the at least one vibrator 7 and the second side 12 is provided with recesses 13 for forming a room 9.
  • the prevention of air leaking into the room 9 takes place by means of a band 17 provided on or along a circumferential edge 21 of the second side 12 of the frame 10, which band is manufactured substantially from a compressible material.
  • a band is used as described in the description of the apparatus 1.
  • the vibrators 7 are provided against the first side 11 of the frame so that the vibrations can be transmitted directly from each vibrator 7 to the suction cup 6.
  • Each vibrator 7 is preferably provided with an eccentric (not shown) which rotates for the purpose of generating the vibrations.
  • the eccentrics each rotate in a substantially vertical plane. A proper embedding of the slab and/or compaction of the sand present under the slab 3 takes place when the eccentrics rotate in the same plane.
  • the direction of rotation of the vibrators 7 provided against the first side 11 of the frame 10 is preferably such that, looking at the top side of the slab 3, the eccentrics rotate towards each other.
  • the method may further comprise: determining a depth over which the slab is embedded in the substrate. This determination may take place visually on the basis of markings provided on a longitudinal edge of the slab 3. However, it is also possible for the determination to take place by means of an assembly comprising first means having a fixed position with respect to the slab and second means having a fixed position with respect to the substrate. The assembly has been designed to stop the transmission of vibrations to the slab when the first and second means have reached a predetermined height relative to each other. Examples of such an assembly have been discussed in the description of the apparatus 1. In many cases, the bottom side 5 of the slab will be smaller than the top side 4. In other words, the slab will be provided with a sloping longitudinal edge.
  • sand is provided against or near the longitudinal edge of the slab.
  • the provision of sand takes place only once.
  • Two slabs can be embedded such that the top sides form virtually one continuous surface.
  • the sand is provided a single time on or in a joint present between the slabs. Providing the sand may be done near the arrow Z shown in Fig. 4 .
  • the invention is not limited to the method shown. It is, for instance, possible for the vibrators to be provided at some distance from the first side 11 of the frame instead of directly against the first side 11 of the frame. It is then, of course, required that such a medium is present between each vibrator 7 and the first side of the frame 10 that vibration generated by each vibrator 7 can be transmitted to the frame 10 designed as a suction cup and the slab 3.
  • the vibrations may be generated by means of electrically driven eccentrics, pneumatically driven eccentrics or hydraulically driven eccentrics, by rotation of the eccentrics. It is also conceivable that vibrations are generated without using eccentrics. It will be clear that, after embedding the slab 3 to a sufficient extent, the suction cup 6 is removed from the slab 3 by letting airflow into the room 9.
  • the suction cup may then be removed from the slab 3 without the slab 3 changing position.
  • the method can largely be carried out automatically.
  • the removal of the suction cup 6 from the slab 3 can take place without manual operations by a worker stationed near the slab 3.
  • Operating the vacuum, hoisting the suction cup, and operating the vibrators will have to be done by a worker.
  • these operations can be carried out remotely from the slab. This promotes safety.
  • adding sand to the substrate near a longitudinal edge of the slab 3 is carried out automatically.
  • the method may also provide such a step.
  • the apparatus may be designed such that sand can be added to the substrate located near the longitudinal edge of the slab prior to or during vibration. The supply of sand can stop automatically when it has been determined that the slab has been embedded to a sufficient extent.
