Definitions

  • the invention relates to the field of the building and more particularly relates to the manufacture of wall coverings.
  • a wall cover also called “chaperone” or “couvertine” is a construction element designed to be placed on the upper face of an exterior wall or wall to protect it against the elements, namely against rain and humidity.
  • the wall coverings are generally obtained by molding a suitable material, for example concrete, resin concrete, reconstituted stone, clay, etc. They can also be made in the form of profiles of metal or metal alloy or plastic.
  • These wall coverings have a width or depth greater than that of the wall to exceed the plumb of the latter. Drip edges are generally formed on the longitudinal edges of the wall cover to facilitate the flow of rainwater, without runoff on the vertical faces of the wall.
  • the invention relates here to the manufacture of wall coverings from a pasty mixture hardened to the desired shape, in particular, but not limited to, a pasty mixture of the concrete type.
  • each wall cover is molded into a two-part mold comprising a mold and a counter mold, at least one of which is moved by means of a jack or the like. It is also known to manufacture wall coverings by using individual molds without counter-molds, and with a more fluid pasty mixture.
  • the wall coverings thus molded generally have a large thickness and dimensions subject to variations.
  • these traditional wall coverings are relatively heavy and difficult to handle.
  • the object of the invention is in particular to overcome the aforementioned drawbacks.
  • the manufacture of wall coverings according to the invention is carried out by a continuous process, the pasty mass being cast and spread continuously on the molds, arranged one after the other, as and when they are displacement in translation.
  • the continuous layer thus deposited is compacted and then cut transversely each time between two successive molds to obtain individual molds each covered with a layer of pasty material of finite length, which corresponds to the shape of a wall cover.
  • the resulting wall cover has precise and regular dimensions, unlike traditional molded products.
  • the invention relates to an installation for manufacturing wall coverings, for the implementation of the method defined above, in which a pasty mixture is used which is put into a desired shape and then cured.
  • the invention also relates to the wall coverings obtained by the method or by the installation of the invention.
  • FIG. 1 shows in side view an installation 10 for the manufacture of wall coverings according to the invention.
  • the installation 10 comprises a sliding track 12 comprising sliding rails 14 arranged in a substantially horizontal position as shown in FIG. figure 3 .
  • This sliding path serves to move in continuous translation of individual molds 16 (four in number on the figure 1 ) as a result of each other.
  • These individual molds have in plan view a rectangular general shape defined by two longitudinal sides and two transverse sides. The molds come in simple contact between them at their respective ends, that is to say by their transverse sides. They are moved in translation in the direction of the arrow F1, that is from left to right on the figure 1 under the action of a displacement member 18, shown schematically here. This displacement member makes it possible to move the molds continuously or discontinuously on the sliding rails 14.
  • the displacement member 18 is constituted by a thrust member, namely a jack 20, for example of hydraulic or pneumatic type, having a push rod 22 terminated by a stop 24 adapted to bear against an end of a mold to move it in the direction of the arrow F1, at the same time as the other molds located in front of it.
  • a thrust member namely a jack 20, for example of hydraulic or pneumatic type, having a push rod 22 terminated by a stop 24 adapted to bear against an end of a mold to move it in the direction of the arrow F1, at the same time as the other molds located in front of it.
  • the speed of displacement of the molds imposed by the displacement member 18 is controlled and may be, for example, of the order of 15 to 25 meters per minute, this range of values being given for information only.
  • the installation further comprises a kneading and pouring device 26 arranged above the sliding track 12 and molds 16 and intended to deposit and form a continuous layer C of a pasty mass P on the individual molds 16 as and as they move.
  • This device 26 comprises a distribution hopper 28 of pasty mass in which is placed a mixer (not shown).
  • the pasty mass is a pasty mixture of thick consistency intended to be spread on the molds and then shaped to the desired profile, the mixture must retain its shape, without sinking or spreading during a subsequent phase of curing, generally by drying at room temperature. 'outdoors.
  • the pasty mass may be, for example, concrete, resin concrete, reconstituted stone, clay mix, and the like.
  • the pasty mass P is then subjected to the action of a compaction device 30 capable of giving a determined profile to the layer C which is deposited on the individual molds in a continuous manner.
  • the compacting device comprises at least one compaction roller 32 of selected profile adapted to conform the upper part of the wall coverings. This roller 32 is rotated in the direction of the arrow F2 around a horizontal axis XX. This compacting roller 32 is followed by a smoothing member 34, also called smoother.
  • the compaction roller 32 and the smoothing member 34 make it possible to give the desired profile to the upper part of the wall covering, ie to the part that will be exposed to the weather, while the molds serve to shape the part. inferior, that is to say the one that will be sealed on a wall.
  • the installation 10 further comprises a cutting device 36 capable of transversely cutting the continuous layer C between two successive molds 16 in order to obtain individual molds each covered with a pasty material layer of finite length, that is to say having the same length as the individual mold, which corresponds to the shape of a wall cover 38.
  • the operation of the cutting device 36 is synchronized with the displacement of the molds in translation, so that the cutting takes place each time between the respective ends of two successive molds.
  • This cutting of the pasty layer makes it possible to cut this pasty layer in the connection zone of two molds, which makes it possible to obtain individual molds each covered with a finite length of pasty mass.
  • These individual molds can then be sent to a storage area (not shown) for hardening the wall coverings.
  • This hardening is generally done by drying in the open air and is followed by demolding.
  • FIG 4 shows an exemplary embodiment of a mold 16 and a compacting roller 32 associated to give a wall cover 38 a double slope section, here two symmetrical slopes.
  • the compaction roller 32 has a shape with two inverted cones 40 and 42 arranged between two flanks 44. of circular shape which have a diameter greater than that of the cones 40 and 42 in their region of larger diameter.
  • the cones 40 and 42 are intended to form the upper part 46 of the wall covering, that is to say the part in the form of a double slope, while the sides 44 of the roll make it possible to form the edges 48 of the wall coverings.
  • the mold 16 comprises an upper surface 50 generally convex, provided with ribs and / or grooves to form the lower portion 51 of the wall cover.
  • the upper face 50 of the mold is connected to two longitudinal edges 52 which contribute to the formation of the wall cover in the region of its edges 48, as will be seen later.
  • the figure 5 shows another embodiment in which the roller 32 makes it possible to form a flat or trapezoidal shape.
  • the roll 32 is formed by a central cylindrical portion 54 surrounded by two frustoconical portions 56 and 58, themselves surrounded by two flanks 44.
  • the upper portion 46 of the wallcover 38 has a flat or trapezoidal section profile. .
  • the figure 6 shows another embodiment wherein the roller 32 has a portion 60 having substantially a general shape diabolo to give the upper portion 46 of the wall cover a rounded section profile.
  • compaction roller 32 is designed to give the desired profile to the wall covering, for example at a slope, with two slopes (symmetrical or not), with a rounded, flat or trapezoidal shape, the list of these forms not being not exhaustive.
  • flanks 44 of the roll 32 make it possible to form the edges 48 of the wall covering over a height of several centimeters in order to give the proportions of a conventional wall covering, for example made of concrete, despite the small section of the wall cover and made.
  • the lower portion 51 of the wall cover is formed by the mold which allows to create ribs and / or grooves for a better sealing of the wall cover on a wall or wall by means of a laying mortar. These ribs make it possible to obtain a better seal in the laying mortar as well as a better resistance to bending.
  • the upper face 50 and the longitudinal edges 52 of the mold 16 also contribute to forming two lateral drip 62 in the lower part of the wall cover.
  • the upper portion 46 of the wall cover is double slope and the slope of each drip 62 (angle A) is identical to the slope of the upper portion 46 of the wall cover (angle B). This makes it possible to stack the wall coverings, once hardened and dried, by increasing and distributing the support surfaces.
  • the figure 8 shows an alternative embodiment in which the longitudinal edges 52 of the mold 16 each have a longitudinal rib 64 projecting to form two grooves 66 forming drops of water in the lower part of the wall cover to prevent the runoff of rain water on the wall. On the figure 8 only one of the two longitudinal grooves 66 is visible, the drawing being in partial section.
  • the figure 9 shows that the compaction roller 32 has a rounded connection region 68 between the cone 40 ( figure 3 ) and the flank 44, which makes it possible to create a longitudinal edge 70 of profile rounded between the upper portion 46 and the edge 48 of the wall cover. Such a possibility is offered regardless of the profile of the compacting roller 32.
  • the cutting device 36 comprises at least one knife 72 with vertical movement and two knives 74 with horizontal movement.
  • the knife 72 comprises a blade 76 provided for cutting the layer of pasty mass on the upper part 46 of the wall cover, while the knives 74 each comprise a blade 78 provided for cutting the layer of pasty mass on the sides, it is to say in the region of the songs 48 of the wall cover.
  • These knives are actuated by appropriate members, for example cylinders, in the direction indicated by the arrows of the figure 10 . They are synchronized with the displacement of the molds so that the cutting is carried out each time between two successive molds. For this, one can provide probes (not shown) for detecting the junction area of two molds to trigger the actuation of the knives.
  • the cutting device 36 has only one knife 72 with vertical displacement. However, it is possible to provide several knives.
  • the knife 72 has a rounded base 80 in the upper part of the blade 76. It is the same for the knives 74 which have similar rounded bases. In this way, the wall coverings will have a rounded edge 82 at each end, in the transverse direction.
  • FIGS. 12 and 13 respectively show a top view and a bottom view in perspective of a wall cover according to the invention, in the example a wall cover section double slope. It can be seen that the wall cover has a ribbed lower portion 76.
  • the wall coverings can thus be formed continuously with various shapes, especially as to their section. Generally, these wall coverings will have a typical length of 30 cm to 1 m for a width of 20 to 40 cm, these values being given here for information only.
  • a concrete is advantageously used.
  • a typical mixture consists of silico-limestone aggregates with a continuous particle size of 0 to 3 mm, 52.5 R class Portland cement, plasticizer and water. This mixture can be colored by mineral pigments if necessary.
  • the drying is preferably carried out in the open air in appropriate storage areas for a period of the order of 8 to 48 hours depending on the external conditions. It is also possible to carry out the drying in an oven.
  • Wall coverings can be made with a wide variety of shapes and sizes and with less thickness than traditional wall coverings.
  • the resulting wall coverings are lighter than traditional concrete wall coverings and easier to handle.
  • Wall coverings have precise and regular dimensions unlike traditional molded products.
