Definitions

  • the subject of the invention is a preparation and transport installation from a mortar to the place of use.
  • the invention is specially adapted for the use of plasters facade but can also be used for the realization of floors, walls, ceilings or slabs, indoors or outdoors.
  • the old technique still used for weak construction sites importance, consists in first of all preparing a mass of dry mortar by mixture with cement of a sand having the desired particle size and of it add water as needed.
  • Such a device comprises a mixer into which the sand and cement or ready-mixed mortar, to mix them with water and the mixture is then poured into a through hopper in a pumping device, for example screw or compressed air, which feeds a projection lance.
  • a pumping device for example screw or compressed air, which feeds a projection lance.
  • the silo pours out, by a hopper, to the lower part of an inclined conveyor-metering device, which dumps dry plaster in a predosing container closed at its base by a stop device for supplying a mixer conveyor associated with projection means.
  • solid materials not consistent such as sand, gravel or even a ready-to-use mortar, can be delivered in flexible containers often called “big bags", containing, for example, one to two tonnes of product.
  • JP-2001-269558 shows such arrangement in which a flexible container is placed by means of lifting on a support provided at the top of an enclosure reserve in which it empties entirely.
  • the spilled material collects in the bottom of the hopper-shaped enclosure, from which the material is taken up and reassembled by an inclined conveyor which opens out in a mixing and pumping device for the mortar thus produced.
  • Such a device is quite bulky and expensive and, so far, it had not seemed profitable to provide such means on a construction site low or medium importance such as a detached house or a small building for which it seemed preferable to use the methods usual by making the mortar on site or by using a mortar ready to use delivered in 30 kg bags.
  • Another problem is that it is often asked to make facade coatings colored in the mass. For that, we can pre-stain the dry mortar in the factory by mixing an additive or a coloring pigment with the constituents, in particular, in the case where use a ready-to-use mortar. We then deliver bags to the site corresponding to the requested color but, when it is necessary to realize several colors, it is necessary to plan the number of bags necessary for each with the risk of delaying work if the number of bags ordered is not not enough or, conversely, to have unused bags.
  • the invention makes it possible to solve these problems thanks to an installation simple and compact, allowing the use, even for construction sites low or medium importance, flexible containers for the supply of materials or ready-to-use mortar, retaining the possibility of adjustment of the composition making it possible in particular to guarantee the color of the coating.
  • such an installation can be powered by flexible “big bag” containers without the need for important lifting and allows to precisely control the proportions of constituents so as to obtain a great regularity of the shade obtained, by carrying out, if necessary, coloring on site with the mortar.
  • the invention makes it possible to solve such problems thanks to a versatile and autonomous installation, easy and economical to use, able to adapt to a wide variety of circumstances and any importance.
  • the invention therefore relates, in general, to an installation of preparation, transport and installation of a mortar, which can be supplied by means of a flexible container filled with dry matter and consisting of an envelope having an upper part provided with a suspension from a lifting means which supports each container to lift it above a reserve hopper into which it pours the material through a lower container emptying orifice, said hopper having a lower part connected by a means for removing the material to a mixing device associated with a pumping device for pressure supply of a mortar transport line leading to the place of use.
  • each container is extended downward by an elongated sheath having an upper end plugged into the drain port and a lower end that goes down in the reserve hopper up to a mass of reserve material formed in said hopper, so that, during the emptying of the dry matter, this forms, inside the connecting sheath, a continuous column which gradually flows into the mass of material in reserve, as and measurement of its evacuation to the receiving section of the device of mixing.
  • the reserve hopper may have a capacity less than the volume of material dryer transported in a container.
  • the lifting means include a means of progressive lifting of the flexible container, at as the material is emptied, so as to compensate the lengthening of the container envelope while maintaining a difference of substantially constant level between the container drain port and the lower end of the sheath opening into the mass of material contained in the hopper.
  • the container suspension member can advantageously be connected to the lifting means by an elastic member tared determining the lifting of the suspension member as and when measurement of the emptying of the container.

  • the mixing device comprises a sheath tubular centered in a longitudinal median plane of the platform and having an inlet port placed in the central part of the platform below reserve hopper and an outlet opening into the device pumping, the latter being mounted at a longitudinal end of the platform.
  • the sheath of the mixing includes a first part limiting a reception room of the material and a second part limiting a mixing chamber of the material and articulated around a vertical axis on the first part so as to be able to be folded back into the carriage transport position, releasing the platform a space on which the pumping device can be raised, the latter being articulated around a horizontal axis on the end longitudinal of the platform.

  • the lifting crane comprises means for adjusting the boom level between a lowered position of taking over a container on a storage area and a raised position for emptying the container in the hopper.
  • this means of adjusting the level of the boom can be ordered according to the variation in weight of the container so as to determine a progressive lifting of the suspension organ as and when measure of the lightening of the container.
  • the container lifting and suspension means include a boom having an inner end hinged about a horizontal axis on the carriage and an outer end provided with a suspension member for a container and means for controlling the pivoting of the boom between a position lowered support by the suspension member of a container placed on a storage area and a raised position for emptying the container.
  • the lifting arrow forms a articulated gantry spanning the platform and comprising a cross horizontal carrying a container hanger and two arms articulated respectively, around aligned horizontal axes, on the two lateral sides of the platform and on which two jacks are supported of the gantry pivoting.
  • the two arms of the gantry can be formed each of two parts mounted sliding on one another and associated with sliding control means for adjusting the length of said arms as a function of a variation in the weight of the container suspended from the crosses.
  • the arrow can pivot between a first position lowered towards a longitudinal end of the container handling platform, a raised position of container emptying and a second position lowered to the other longitudinal end of the platform for transporting the trolley from one place of use to another.

  • the installation according to the invention is specially adapted for flexible container feeding, it can however, by simple and quick modifications, be fueled also, either from a silo associated with a means of evacuation opening directly into the reserve hopper after separation of the lifting means, either by means of a mortar transport member wet type "spinning top" the mortar being poured directly at the entrance of the pumping device, after separation of the mixing device.
  • Figure 1 there is shown schematically a first mode of realization of the invention, applied to a site of low or medium importance such as the construction of a single house A.
  • the installation according to the invention can be supplied in flexible containers filled with a large quantity, for example from 500 kg to 2 tonnes of dry matter such than a ready-to-use mortar.

  • the invention makes it possible to produce a particularly compact arrangement in which all means necessary for the preparation and installation of the mortar, are grouped together on a mobile carriage B which can thus be easily moved from one place of use to another without worrying about the importance of the site.
  • this mobile carriage essentially comprises a frame 1 forming a horizontal platform substantially rectangular in shape and resting on the ground by one or two axles, respectively one or two rear axles 11 which support the main part of the load and, at the front, a steerable “jockey” wheel 12 which is articulated around a vertical axis and can be oriented by a drawbar 13.
  • the chassis 1 is advantageously held by crutches 14 of adjustable level, which are raised when the carriage moves.
  • Such containers generally have, when full, a roughly square shape, which makes it easier to place them next to the other, on soil S, as shown in Figures 1 and 3.
  • the mobile carriage B brought in tow on site is therefore placed and oriented so that it can move along or in front of this row of containers.
  • Each container consists of a flexible envelope 7 in the form large bag provided, at its upper part, with hanging means such as straps 71 and the lower part of which forms a substantially flat bottom 72 provided, in its central part, with a drain orifice 70.
  • the bottom 72 of the envelope 7 of the container is extended by an elongated sheath 73 having an upper end plugged into drain port 70 and a lower end going down inside a reserve enclosure 3 up to the level of its part lower hopper-shaped 3.
  • This elongated sheath 73 is equipped with a closure means removable not shown in the drawing and which can be constituted, simply, a link that can be opened by hand.
  • the material M contained in the casing 7 pours out through the lower orifice 70 and the sheath 73 and forms a mass M 2 which rises, in the lower part 31 of the hopper 3, including the lower end of the sheath 73. Therefore, if the flow stops by itself as long as this mass M 2 is not discharged, the sheath 73 being filled with a column M 1 of material.
  • the reserve enclosure 3 forms a hopper mounted on a lateral part 16 of the chassis 1 of the carriage extending on the side of the steering axle 12 by relative to the lifting means which is mounted in the central part 15 of the platform and will be described later.
  • the hopper 3 is centered on the longitudinal axis 10 of the chassis 1 of the carriage and advantageously has a truncated pyramid shape inverted with a square base and limited by four flat faces which converge down to a rectangle-shaped outlet port 32 elongated, placed in a plane inclined to the horizontal.
  • Hopper 3 is, on the other hand, oriented so that the vertical median plane P1 of the orifice 32 makes an angle K with the vertical median plane P of the carriage B.
  • the square base of the hopper 3 is located in a horizontal plane, slightly above the upper face of chassis 1 of the carriage and is preferably closed by a cover 33 consisting of a flat wall at the center of which is formed an introduction orifice 34 centered on an axis vertical 10 placed in the longitudinal median plane P of the carriage.
  • This orifice 34 has a diameter equal to that of the drain sheath 73 a container C, which can thus enter the interior of the hopper 3 when the container C, suspended from the lifting means 2, is centered on the axis 10 of the hopper, in the position shown in Figure 2.
  • the hopper 3 is associated with a seat belt allowing safe access below the container C and constituted, for example, a circular tube 35 fixed by legs on the frame 1 to a short distance, for example ten centimeters, above the cover 33 of the hopper 3.
  • container C is not placed on the tube 35 which is simply a seat belt but remains suspended, permanently by lifting means 2 by straps 71.

  • the suspension member 23 can thus move radially, along the arrow 21, between an internal position 23a and an external position 23b.
  • the suspension hook placed in its external position 23b therefore describes a circular path T shown in phantom in Figure 3.

After removing these containers, it is possible to put the carriage B back on its wheels and move it longitudinally to cover other containers in the row.
  • the containers are lifted by means of the jack 24 for adjusting the height of the boom 21, which is first placed in the low position F 1 to bring the hook 23 above a container C in the row and hang the suspension straps 71, then raised to its high position F 2 , by lifting the container C.

Since the flexible envelope 7 of the container is stretched when the container is full and tends to lengthen when it empties , it is necessary to compensate for this elongation by raising the suspension point 23 of the container as and when emptying 70 to a substantially constant level.
  • the means 24 of adjustment of the level of the jib 21 of the crane 2 which can be a jack hydraulics controlled by a microprocessor depending on the variation, measured by a sensor, of the weight of container C suspended on the hook of the crane.

  • the calibration of the springs corresponds to the weight of a full container C.
  • the elastic member 27 is adjusted so that the bottom 72 of the container passes just above the seat belt 35.
  • the suspended container is then connected to the reserve hopper 3 by the sheath 73 which can be opened.
  • the weight of the container C decreases and the hook 23 rises upwards under the action of the calibrated suspension member 27, accompanying the narrowing of the envelope 7 of the container whose flattened shape 7 'is indicated in phantom in figure 2.
  • the lower orifice 70 of the casing 7 remains at a substantially constant level and the sheath 73 is filled with a column of material 71 which flows as this material M 2 is extracted by the evacuation means 4 which will be described later.
  • the drain sheath 73 can have a fairly small diameter, for example, of about 1/4 or 1/5 of that of the bottom 72 of container C when it is full.
  • the reserve hopper 3 can have a reduced volume since it must simply contain a reserve mass M 2 sufficient to serve as a buffer in order to continue feeding the mixing device 5 for the time necessary for replacing d 'a container.

  • the device mixing which consists, as before, of a tubular sleeve 51 associated with means for conveying the material between an inlet orifice 55 and an outlet 56, is centered on the longitudinal axis 10 of the platform, the inlet orifice 55 being placed in the center thereof and the orifice of outlet 56 at the longitudinal end of the platform.
  • the device of mixing therefore extends over the lateral part 16 of the platform, the means for controlling the control operation 8 being placed, as before, on the second lateral part 17.
  • the reserve hopper 3 is placed above the device 5 and is connected to the inlet tubing 55 so as to lead directly into the receiving section 52 of the mixing 5.
  • the drain sheath 73 is then shorter and the means 4 can be removed, the material flowing from the container being taken care of directly in the receiving section by the organ for conveying the material associated with the tubular sheath 51.
  • the pumping device 6 is fixed on the end longitudinal of part 16 of platform 1, below the orifice of output 56 of the mixing device 5.
  • the arrow 2 ′ can have a variable length, the two arms 21'a, 21'b being made up of two telescopic parts sliding one inside the other and each associated with a 24 'cylinder not shown in detail, which adjusts the level of the suspension 23 'depending on the weight variation of container C, at by means of a regulation system in position and pressure of the cylinders 24 ' comprising a microprocessor associated with a sensor for measuring weight variations of the container suspended from the hook 23 '.
  • a regulation system in position and pressure of the cylinders 24 ' comprising a microprocessor associated with a sensor for measuring weight variations of the container suspended from the hook 23 '.
  • the 24 'cylinders allow completely fold the two arms 21'a, 21'b and the gantry 2 'can be folded back over the control means 8, in the position shown in Figure 7.
  • the sleeve 51 of the mixing device 5 can advantageously be made up of two parts 52, 53 constituting respectively the receiving chamber and the mixing chamber and hinged on each other around a vertical axis so that the part of mixing 53 can be folded down along the receiving part 52 in thus freeing up, at the longitudinal end of the platform 1, a space free on which the pumping device 6 can be raised, the latter being articulated around a horizontal axis 60 on the corresponding longitudinal side of platform 1.
  • the dry matter is supplied by a transportable silo 7 ′ mounted on legs which span the platform 1 so that the orifice outlet 70 'from the silo opens above the reserve hopper 3.
  • the installation can also be supplied with mortar wet prepared in advance and delivered to the site by a truck of the type "Concrete mixer".
  • the pumping 6 must simply be fitted with an extension 66 in which opens the chute of the router, the mortar thus spilled being immediately taken over by the pumping device to be projected by lance D.
  • evacuation devices 4, mixing and pumping 6 can be provided to convey a material dried. If the installation is supplied with ready-to-use mortar, we could therefore, in known manner, transport the dry matter to the lance 65 and introduce the water necessary for leaving it, just before the projection.
