Definitions

  • the present invention relates to a method of manufacturing a building element imitating a stack of dry stones, as well as an installation making it possible to implement this method.
  • the applicant begins by placing the stones - for example granite-cut waste - side by side on the bottom of a mold whose top is open and whose sides have an identical shape. to that of the element to be manufactured. It possibly places on the layer of stones a metal reinforcement intended to improve the mechanical resistance of the finished element, then pours fluid cement into the mold. After setting the cement by drying, it removes the finished element from the mold.
  • the stones for example granite-cut waste - side by side on the bottom of a mold whose top is open and whose sides have an identical shape.
  • the invention aims to solve these problems by proposing a manufacturing process of the kind mentioned which is easy and economical to implement and which makes it possible to obtain finished elements of very good quality, with a low percentage of scrap, while being suitable for medium or large series production.
  • the meshes of the grid constituting the mold base are naturally determined according to the average dimensions of the stones used, so that they do not allow the smallest of these stones to pass, while being large enough not to obstruct the passage water jets to remove excess cement.
  • a metal reinforcement for example a trellis or a mesh
  • the compression of the cement in the mold can be carried out by means of a movable pressure plate, parallel to the bottom of the mold in the form of a grid, this pressure plate constituting in a way the cover of the mold.
  • the projection of water onto the stones through the grid is preferably done in two phases, a washing proper by pressurized water jets, followed by rinsing by sprinkling in rain (by production of droplets).
  • the installation which is also the subject of the invention, and which makes it possible to implement this process, is characterized in that it comprises a series of movable molds placed one after the other on a track bearing, the latter passing through a series of successive stations in which the various steps of manufacturing the element are carried out, conveying means being provided which make it possible to transfer the molds from station to station.
  • each mold is composed of two distinct parts capable of being joined to one another: - an upper part in the form of a frame whose internal shape corresponds to the contour of the element; - a lower part carrying the bottom in the form of a grid and provided with wheels ensuring its rolling on the track.
  • the cement compression device which equips the installation, advantageously comprises a carriage guided in translation parallel to the track and arranged to accompany the mold during the cement compression and water spraying stages, as well as a press plate movable relative to the carriage, means being provided for moving this press plate against the mold in order to compress the cement therein.
  • the building element 1 shown in Figure 1 is a generally rectangular plate, dimensions 50 x 25 x 8 cm; the opposite small sides 12-13 of this plate are zigzag shaped.
  • This element is essentially made of cement 11 but is provided on one of its faces with a layer of exposed stones 10 just seated and practically contiguous, retained by the cement.
  • cement is meant not only the actual cement (mixture of calcium carbonate and aluminum silicate), but in general any curable binder which can be used in construction, for example concrete.
  • a metal reinforcing frame 14 such as a lattice of crisscrossed welded iron bars for example.
  • the stones 10 are for example waste from the size of granite, pebbles, shales, white stones from Touraine, etc. Their dimensions are chosen according to local availability and / or the desired construction style.
  • the assembly of the elements 1, for the realization of a construction is done in a similar way to the assembly of concrete blocks or traditional slabs, using mortar, cement or mortar.
  • the interlocking of the zigzag edges of two contiguous plates, during their assembly, makes it possible to hide the joints between the plates, giving the construction the appearance of a stack of particularly aesthetic dry stones.
  • This type of prefabricated element can be used for the construction of buildings and various pavements, in particular of walls or low walls, chimneys, barbecues, wells, steps and pavements for gardens and pedestrian ways.
  • the mold shown in FIGS. 2 and 3 consists of an upper part 2 and a lower part 3.
  • Part 2 has the form of a frame having two opposite sides 20 rectilinear and two other sides 21, 22 in broken lines, the shape and the dimensions of the interior space delimited by these sides corresponding to the outline of element 1 that we want to manufacture.
  • the lower part 3 also has the shape of a frame, of dimensions equal to or slightly greater than those of the frame 2; this frame 3 supports a horizontal grid 30 which consists of two crossed series of parallel bars.
  • the mold part 3 is mounted on two pairs of idler wheels, which are guided in translation on a pair of horizontal rails 4, this part 3 therefore constituting a mobile carriage.
  • Figure 4 illustrates the procedure for manufacturing a building element of the kind shown in Figure 1, using the mold which has just been described; this figure schematically shows the various stations of the installation making it possible to implement this process.
  • the track 4 of the carriage 3 travels all of the stations where the various stages of manufacturing the element 1 will be carried out.
  • a plurality of identical molds 2-3 are provided, which can circulate one after the other on track 4, this to avoid time dead at each work station.
  • a suitable conveyor such as a movable chain 40 fitted with pusher cleats 41 (partially shown) makes it possible to drive the molds into the installation, from station to station; the molds move from left to right in Figure 4; the speed of their movement is for example of the order of 0.1 to 0.2 m / s.
  • the installation comprises a station (II) equipped with a washing device 6 and an adjuvant spraying device 7, both arranged above the trajectory of the molds; these devices are fitted with downwardly directed liquid spray nozzles.
  • the installation includes a station (IV) equipped with a cement compression device 5, placed above the trajectory of the molds.
  • This comprises a carriage 51 fitted with wheels 55 and guided in translation on a horizontal track 56, parallel to track 4.
  • Track 56 consists of upper and lower rails 560 respectively 561, which positively hold the wheels 55 to both up and down.
  • This device 5 also includes a pressure plate 50 carried by the carriage 51 and movable in translation relative to the latter in the vertical direction.
  • Vertical columns 54 guide the plate 50 relative to the carriage 51, while a double-acting hydraulic cylinder 52 ensures the movement of the plate 50, by means of a cylinder rod 53.
  • the pressure plate 50 is a rectangular plate of dimensions slightly larger than those of frame 2.
  • a square piece 57 On the top of the carriage 51 is fixed a square piece 57 to which is attached the free end of a horizontal control rod 58.
  • the latter constitutes the rod of a hydraulic or pneumatic cylinder, single acting, arranged to move positively the carriage 51 in the opposite direction to that of the mold 2-3 (arrow H), and so as not to hinder the movement of said carriage - by putting its piston chamber at atmospheric pressure - when the latter moves in the same sense as the mold (arrow I).
  • a station (V) Immediately downstream of the station (IV) is a station (V) equipped with a washing device 8 and a rinsing device 9, these two devices being located below the trajectory of the molds, and being provided with water spray nozzles which are directed upwards.
  • the stroke of the jack 59 is sufficient to allow the carriage 51 to pass vertically over the two devices 8 and 9.
  • Appropriate control members make it possible to start the projection devices 6, 7, 8 and 9 and the jacks 52, 59 in synchronism with the passage of the molds in the installation.
  • An operator located at the first station places the upper part 2 on the lower part 3 of a mold, and fixes it there by means of the clamping members provided for this purpose.
  • the mold 2-3 then passes to the station (II) under the devices 6 and 7 which respectively, by spraying water, wash the stones 10 (as well as, if necessary, the frame 14) and, by spraying, coat them with an appropriate adjuvant of known type intended to promote the bonding of the cement.
  • the upper part 2 of the mold is filled with fluid cement which covers the stones 10 and the frame 14 (station (III)).
  • This filling can be carried out either manually by one or more operators, or automatically by means of a discharge hopper placed above the trajectory of the molds, or even semi-automatically.
  • the mold filled with cement then arrives at the compression station (IV), the pressure plate 50 is lowered by extension of the jack 52, so as to come to bear against the mass of cement 11 (arrow J). It follows a pressurization of the cement which is forced to occupy completely and homogeneously the entire interior space of the mold, the cement seeping in particular from top to bottom between the stones 10 to the grid. 30 ; during this compression, the plate 50 plays the role of the mold cover and shapes the internal face of the element 1.
  • the compression force developed on the cement by the plate 50, and transmitted to the carriage 51, is absorbed by the upper rails 561 of the track 56, so as to prevent the carriage from being raised.
  • the device 5 accompanies the mold in its translational movement on track 4, while the piston chamber of the jack 59 is brought to atmospheric pressure (arrow I).
  • This assembly thus crosses the station (V) (arrow K) where the visible part of the stones 10, bearing against the grid 30, is washed and then rinsed by successive jets of water at high and low pressures produced by the devices 8, respectively 9.
  • the washing jets remove the cement which has infiltrated not only on the visible parts of the stones, but also which has lodged in the interstices separating the stones up to the grid 30, cement which could remain visible on the product. finished and remove from it its appearance of dry stones.
  • This washing is preferably done at an adjustable pressure, so that the power of the jets can be adapted to the fluidity of the cement and to the sizes of the stones used; As an indication, the pressure of the water jets is for example between 0.5 and 5 ⁇ 105 Pa.
  • the subsequent rinsing by droplets of water with the aid of the device 9 is intended to remove stains and splashes of cement which may remain after washing, or which may be produced by this washing itself.
  • the jack 59 which had retracted as a result of the advance of the carriage 51 (itself driven by the mold 2-3) is put in extension, causing the return of the device 5 to the station (IV) (arrow M). This device is then ready to act on the next mold.
  • the mold 2-3 is then sent (arrow N) to a storage and drying area not shown, for example on a drying carousel where the setting of the cement takes place.
  • a storage and drying area not shown, for example on a drying carousel where the setting of the cement takes place.
  • an operator demoulds the finished element 1; the extraction of the element from the mold is facilitated by the fact that this mold is in two parts, the latter being able to be advantageously separated for demolding.
  • the raceway 4 is preferably a closed circuit, which allows the empty mold 3-4 to be brought back to station 1 after demolding, this empty mold then being ready to receive a new load.
  • the molds are not necessarily fixed on the carriages but can be simply placed on them.
  • the grid constituting the bottom of the mold is not necessarily formed of crossed bars.
  • the term "grid” means any perforated plate capable of properly retaining the stones and the cement in the mold while allowing the passage of the jets of washing water.
