Definitions

  • the present invention relates to a method for treating bricks made of clay and baked in the oven.
  • clay bricks baked in the oven which are suitable for interior facing and exterior facing can be classified according to their shaping process and according to their cooking process.
  • Salvaged bricks are kiln-baked clay bricks that are salvaged from building demolition. They are separated from each other and cleaned. Remains of mortars adhere to it to a limited extent. They are used in new building sites in rustic or historic style, where no specific requirement can be posed with regard to the similarity of the bricks to be implemented and those of existing buildings. New facade bricks can also be used, but it is obviously impossible to obtain the appearance of old masonry with new bricks.
  • the salvaged bricks present their prolonged exposure to the weather for several years, demolition work, loading, transport, unloading and cleaning, chipping and irregular shapes and a rough appearance on the facing surface.
  • Document DE-A-2922393 discloses a process for lapping the edges of concrete pavers used to cover the ground of tracks or certain covered spaces, in order to prevent walkers from tripping.
  • the concrete pavers are rolled on top of each other in a rotary drum at smooth wall.
  • the body of the pavement does not undergo any deterioration and neither does it take on an old or rustic appearance.
  • the present invention seeks to remedy this drawback and proposes a method and a device for giving new bricks the appearance of old facade bricks, presenting various kinds of damage, a rough appearance on the facing faces, worn sides. and rounded like those which appear following demolition, change and unloading work, cleaning and exposure for several years to bad weather.
  • fresh baked bricks are placed on a conveyor belt which leads them into a sandblasting tunnel and a blowing tunnel in order to remove all traces of sand.
  • the addition of mortar to the drum can be carried out after the treatment of the bricks in the drum where they fall on each other, but it is preferably carried out at the same time as the above treatment.
  • the addition of mortar can also be carried out during or after the pouring of the bricks, or during the stacking of the bricks, in which case the bricks are treated layer by layer.
  • the present invention also relates to a device for the treatment of bricks according to the method according to the invention.
  • An example device includes a tunnel with a sandblasting device which projects sand onto the bricks to give them a tarnished appearance over time, similar to the appearance of bricks subjected to weathering.
  • the bricks are then placed in a drum provided with various obstacles, spikes and irregularities which entrain the bricks one on the other so that they lose their sharp edges and undergo degradation in the bricks even similar to those caused during the work of demolition.
  • the device is provided with a means intended to bring mortar, aggregates or a mixture of these and optionally water into the drum.
  • the drum is supported on rubber wheels so as to obtain agitation of the drum.
  • Figures 1 to 4 show various stages of the method according to the invention.
  • a device is shown by way of example.
  • Figures 1, 3 and 4 are side elevational views of an exemplary device, partially broken away in Figure 3, while Figure 2 is a partially broken away end view of the device from which a closing valve.
  • the fresh bricks 2 baked in the oven are placed on a mobile support constituted for example by a conveyor belt 13 which leads the bricks into a sanding tunnel 4 using sand and compressed air and a blowing tunnel 22 intended to remove all traces of sand by projection of compressed air.
  • the sand and debris from bricks are collected in tanks 30, 31 arranged under the tunnels 4 and 12 above.
  • the bricks are then placed in another mobile support constituted for example by a drum which is driven in rotation so as to cause the bricks 2 to fall on each other, during a determined time interval, during which the bricks 2 lose their sharp edges and undergo degradations giving them the appearance of old bricks or a rustic appearance.
  • another mobile support constituted for example by a drum which is driven in rotation so as to cause the bricks 2 to fall on each other, during a determined time interval, during which the bricks 2 lose their sharp edges and undergo degradations giving them the appearance of old bricks or a rustic appearance.
  • the drum 1 is driven in rotation using a motor 3.
  • This motor 3 is fixed on a tilting table 10 which carries a certain number of supports 11 provided with rubber wheels 12.
  • the supports 11 have an upper surface which follows the shape of the outer surface of the drum 1.
  • Several rubber wheels 12 are mounted on axes distributed along this surface, so as to maintain the drum on the frame.
  • the aforementioned wheels 12 can rotate about an axis B-B parallel to the axis A-A. It is possible to obtain a movement agitating the drum 1.
  • the cylindrical drum carries at each end an annular flange 20 which bears against guide wheels 27.
  • the guide wheels 27 are mounted on axes 23 fixed to supports 21. These guide wheels fulfill the function of stops to prevent any movement of the drum 1 in a direction perpendicular to the rotational movement of the drum 1.
  • the drum 1 is for example provided, on the inner side with various kinds of removable obstacles, unevenness and projections 5 (see FIG. 2).
  • the protrusions 5 are exchangeable obstacles which can have various shapes and dimensions and are generally made of steel and are detachably mounted, so that they can be easily removed and exchanged.
  • the drum 1 has two openings 6, 7 which are closed by means of a valve 8.
  • the valve 8 consists of a plate which can slide along the rail groove 9.
  • the valve 8 is raised to introduce therein the bricks brought by a conveyor belt 13.
  • the bricks are possibly moistened.
  • the speed of rotation which is required by the obstacles or projections 5 is adapted to cause the desired chipping.
  • the type of treatment, the speed of rotation and the duration of the treatment are determined according to the kind of brick and the desired result.
  • the parameters can for example be determined experimentally beforehand or be modified on the basis of intermediate visual controls.
  • the instructions can also be programmed in advance and controlled for example by a computer staff.
  • a quantity of mortar is brought into the drum in solid or liquid form.
  • the mortar adheres locally to the bricks 2 so that, after treatment, bricks are obtained which have the appearance of recovery bricks lined with particles of hardened mortar which adhere to them.
  • the dosage, color and composition of the mortar can naturally be adapted to obtain the desired or required result.
  • the mortar which adheres to the bricks 2 can, under ideal conditions and in the absence of bad weather, harden, which improves the quality and the adhesion of the mortar to the brick.
  • This mortar can be brought into the drum 1 using a screw pump 17 and a flexible pipe 18 (see Figure 3).
  • the drum 1 After completion of the treatment, the drum 1 continues to rotate slowly.
  • the drum 1 is raised in the pouring position using a jack 15.
  • the frame 10 is connected to a frame 13 mobile mounted on wheels by an axis 14 and the cylinder 15 by which the frame can tilt relative to the frame 13 around the axis 14 (see arrow D in Figure 4) to facilitate the removal of bricks from the drum.
  • the valve 8 is then opened.
  • the bricks 2 are poured from the drum 1 which rotates slowly.
  • the bricks preferably fall from the drum onto an inclined, movable net 16 or onto a second conveyor belt 20 ′ which brings the bricks 2 to the warehouse.
  • the bricks produced have all the properties of recent bricks. Thanks to the fact that only very good quality bricks 2 are taken into account for the aging process, a qualitatively perfect elite product is ensured. This product has never been subjected to natural decline or prolonged heat from bad weather and despite this it has rustic properties and the beauty of reclaimed bricks.
  • the finished product is applicable for interior and exterior siding and it can replace the salvaged brick for which there is a shortage on the market.
  • the bricks are optimally mixed in the drum by various movements, which has the advantage that color differences no longer appear in the plane of the facade.
  • the stones can be subjected to a preliminary examination so that the required requirements can be met.
