Definitions

  • the present invention relates to a sliding formwork machine for making concrete pavements, of the type comprising a main frame provided with contact members with the ground spaced transversely and allowing it to advance on the ground, two lateral shutters spaced transversely and extending longitudinally between the members in contact with the ground, a main extrusion plate extending transversely between the lateral forms and forming with them a sliding form in the form of a tunnel for the extrusion of a mass of concrete and the molding thereof into a thick slab as the machine advances, the main extrusion plate being mounted vertically movable relative to the main chassis, adjustment means mounted between the main chassis and the main plate extrusion to adjust the height thereof relative to the ground and, consequently, the thickness of the slab to a chosen value, and supply and dist means ribution of concrete arranged at the front of the main frame to deliver said mass of concrete on the ground in front of the main extrusion plate.
  • Slipform machines are well known (see US Patent 4073592, US 4312602, US 4025217, U S 3 1 77 784 and DE 2108846).
  • machines of the "Guntert and Zimmerman" type are known in particular. They are in particular described by Messrs RAY and Charonnat on pages 99-132 of the Liaison Bulletin Laboratory Highways, n e 95, May-June 1968 Reference 2 231. They are used to make concrete pavement, reinforced or no, at high rates of up to 200 m 3 per hour with a minimum of human intervention. If the concrete is not reinforced, the concrete is poured directly in front of the machine by means of trucks.
  • the reinforcements are placed in front of the machine as and when they advance, In the latter case, the trucks no longer have direct access to the extrusion plate of the machine and we must have use of a lateral feed (see Figure 9, page 104, in the aforementioned Bulletin), composed of a receiver hopper offset laterally to receive the concrete from the trucks, and feed and distribution belts to transport the concrete from the receiving hopper and distribute it in front of the extrusion plate.
  • a lateral feed see Figure 9, page 104, in the aforementioned Bulletin
  • the longitudinal reinforcements must be positioned at regular intervals in the transverse direction over the entire width of the surface to be concreted and adjusted in height by elements called "spacers" serving both as reinforcements transverse and support for longitudinal reinforcement.
  • the object of the present invention is to remedy these drawbacks by positioning the longitudinal reinforcements, in height and in separation, only in the immediate vicinity of the extrusion plate, without using spacers.
  • the machine according to the present invention is characterized in that it comprises an additional extrusion plate which extends transversely between the lateral forms and which is located at a distance in front of the main extrusion plate and at a height from the ground which is lower than that of the main extrusion plate, and in that the concrete supply and distribution means are arranged to deliver a mass of concrete on the ground also in front of the additional extrusion plate.
  • the present invention is based on the observation that the concrete layer obtained at the outlet of an extrusion plate is compact and hard enough to support the weight of objects placed on it.
  • the additional extrusion plate (first extrusion plate considering the direction of advance of the machine) which is located one or two meters in front of the main extrusion plate (second extrusion plate considering the direction of advance of the machine)
  • first extrusion plate considering the direction of advance of the machine
  • second extrusion plate considering the direction of advance of the machine
  • the main extrusion plate then makes it possible to mold a second layer of concrete, over the first layer of concrete and the inserts placed on it, and to achieve the total thickness of concrete desired for the final slab. In these conditions, it becomes possible to dispense with the spacers which were previously necessary to support the longitudinal reinforcement at the desired height. As a result, the problem of installing spacers over the entire width of the surface to be concreted is completely eliminated.
  • transverse reinforcements For positioning the longitudinal reinforcement at regular intervals over the entire width of the surface to be concreted and for positioning it at the desired height, it suffices to provide guide elements, spaced transversely, which are fixed to the additional extrusion plate substantially in the plane of its underside or below it.
  • a distributor of transverse reinforcements can be provided immediately behind the additional extrusion plate for depositing transverse reinforcements on the longitudinal reinforcements, across them, one by one at a rate depending on the speed of advance of the machine.
  • Figures 2a, 2b and 2c are partial views, on a larger scale and in section along lines a, b and c, respectively, of Figure 1.
  • FIG. 3 shows, on a larger scale, a part of the machine of FIG. 1.
  • Figures 4 and 5 schematically show, respectively from the front and from above, the machine of Figure 1.
  • Figure 6 is a view similar to Figure 1 showing a variant.
  • Figures 7a, 7b and 7c are views similar to Figures 2a, 2b and 2c, respectively in the case of the machine of Figure 6.
  • FIG. 8 schematically shows, from above, the machine of FIG. 6.
  • Figure 9 is a view similar to Figure 3 showing another embodiment of the guide elements associated with the additional extrusion plate for guiding the longitudinal reinforcement.
  • FIG. 10 is a perspective view showing, on a larger scale, a guide element used in the machine of FIG. 9.
  • Figures 11 and 12 show how the longitudinal reinforcement can be released from the guide elements.
  • Figure 13 is a sectional view along line XIII-XIII of Figure 9, showing another detail of the machine.
  • the machine represented in FIGS. 1, 4 and 5 comprises a main chassis 1 provided with two tracks 2 which are driven by a motor (not shown) and which allow the machine to advance on the ground, two lateral forms 3, located respectively near the tracks 2, and a main extrusion plate 4, which extends transversely between the side forms 3 and which forms with them a sliding form in the form of a tunnel.
  • the main extrusion plate 4 is carried by an auxiliary chassis 5 which is mounted vertically movable relative to the main chassis 1 and whose height position can be adjusted by means of four hydraulic cylinders 6 (only two of the cylinders 6 are visible in Figure 4).
  • a servo system (not shown) which comprises wires stretched above the ground on each side of the machine and feelers in contact with the wires and which acts on the supply of hydraulic fluid to the jacks 6, makes it possible to maintain the auxiliary frame 5 and, consequently, the main extrusion plate 4 at a predetermined level by the tensioned wires and thus guarantee the uniformity of the upper surface of the concrete slab molded by the machine despite the irregularities of the ground encountered by the tracks 2 during the advance of the machine.
  • the machine shown in Figures 1, 4 and 5 further comprises a lateral feed device 7 for bringing concrete to the front of the main extrusion table 4 and for distributing it over the entire width of the latter between the side forms 3.
  • the lateral feed device 7 comprises an auxiliary frame 8, the rear end of which is connected to the main frame 1 and the front end of which is provided with two wheels 9, a receiving hopper 11 which extends laterally outward from one side of the front part 8a of the auxiliary frame 8, another hopper 12 mounted in the front part of the auxiliary frame 8 between the wheels 9, an endless belt 13 for transporting concrete from the receiving hopper 11 into the hopper 12, and an endless distributor belt 14 for transporting the concrete backwards from the hopper 12 to a location in front of the main extrusion table 4.
  • the distributor belt 14 is pivotally mounted on the auxiliary frame 8 by means of an articulation 15 of vertical axis and being able to move relative to the auxiliary frame 8 in the longitudinal direction of the machine.
  • the other end of the distributor belt 14 is suspended from the cables 16 from a carriage 17 which can be moved by drive means (not shown) in a reciprocating movement along a transverse gantry 18 which is part of the auxiliary chassis 8 .
  • a ramp of vibrating needles 19 capable of emulsifying the concrete when they are vibrated, is mounted just in front of the main extrusion plate 4,
  • the machine further comprises an additional extrusion plate 21, which extends transversely between the side forms 3 approximately 1 to 2 meters in front of the main extrusion plate 4 and, of course, in front of the ramp of vibrating needles 19.
  • Another ramp of vibrating needles 21, identical to the ramp 19, is mounted in front of the extrusion plate 21.
  • the tubes 23 extend longitudinally forward beyond the area into which the mass of concrete is poured onto the ground by the distributor belt 14, and they are fixed in their front part to a transverse vertical plate 25 (figure 1), which delimits the aforementioned zone towards the front and which is fixed to the side forms 3. As shown in FIG. 3, the tubes 23 extend rearwards to the rear edge of the extrusion plate 21 .
  • the extrusion plate 21 is carried by an auxiliary frame 26 ( Figure 3) which is mounted vertically movable between the side forms 3 by means of slides (not shown). Screw jacks (not shown), carried by the side forms 3 and which can be actuated manually or automatically by motors, make it possible to adjust the height position of the auxiliary frame 26 and, consequently, the height position of the plate d extrusion 21 and tubes 23 relative to the ground, therefore the thickness of the layer of concrete extruded and molded by the extrusion plate 21.
  • the loader 27 is essentially constituted by a casing 29 which extends over the entire width of the extrusion table 21 between the side forms 3 and which is provided, at its upper part with a pivoting cover 31 making it possible to introduce therein a reserve of transverse reinforcements 28.
  • the casing 29 has an opening 32 located just behind the rear edge of the extrusion plate 21 and the rear orifice of the tubes 23.
  • the opening 32 is provided with a hatch or valve (not shown) which is repeatedly opened and closed by appropriate control members at a rate depending on the speed of advance of the machine, in order to deposit the transverse reinforcements 28 one by one on the longitudinal reinforcements 24 with a predetermined spacing.
  • a hatch or valve (not shown) which is repeatedly opened and closed by appropriate control members at a rate depending on the speed of advance of the machine, in order to deposit the transverse reinforcements 28 one by one on the longitudinal reinforcements 24 with a predetermined spacing.
  • the auxiliary chassis 8 has, in its front part 8a, a width that is narrower than the distance between the side forms 3. Under the front part 8a of the auxiliary chassis 8 are fixed other tubes or trumpets 33, spaced transversely, to guide) the longitudinal reinforcements 24.
  • the number of tubes 33 is equal to the number of tubes 23 of the first set of tubes, and they are divided into two groups, namely a first group of tubes 33a which are spaced transversely across the entire width between the wheels 9 and which are axially aligned with corresponding tubes of the first set of tubes 23, and a second group of tubes 33b, which correspond to the remaining tubes of the first set of tubes 23 and which are offset from these remaining tubes towards the center line longitudinal of the machine so as to also be between the wheels 9 of the auxiliary chassis 8, As is more particularly visible in FIGS. 1 and 5, the second group of tubes 33b is located in front of the first group of tubes 33a,
  • the machine further comprises a deflector 34, which is located immediately behind the discharge end of the distributor belt 14 and which can pivot around a transverse horizontal axis 35 between a first position (shown in line solid in Figure 1), in which the concrete from the distributor belt 14 is directed towards the main extrusion plate 4, and a second position (shown in phantom in Figure 1) in which the concrete is directed towards the plate extrusion 21.
  • the deflector 34 can be pivotally mounted either on the support structure of the distributor belt 14, in which case the deflector 34 has substantially the same width as the distributor belt 14, or on the auxiliary frame 8, in which case the deflector 14 extends over the entire width between the side forms 3.
  • the trucks come in reverse and unload the concrete into the receiving hopper 11.
  • the concrete is then transported by the feed belt 13 to the hopper 12 from where it is transported by the distributor belt 14 which distributes it, in combination with the deflector 34, either in front of the main extrusion table 4, or in front of the additional extrusion table 21,
  • FIG. 2a shows the first layer of concrete 36 being formed by the extrusion table 21.
  • the longitudinal reinforcements 24 are respectively supported by the tubes 23 in which they slide freely.
  • FIG. 2b is a theoretical cross section of the first layer of concrete 36 in the interval between the two extrusion tables 21 and 4, As can be seen from FIG. 2b, the longitudinal reinforcements 24 are deposited in the hollow impressions 37 left by the tubes 23 during the previous phase. The longitudinal reinforcements 24 are thus perfectly positioned in height h and in spacing e.
  • the transverse reinforcements 28 are deposited one by one by the loader 27 and are also perfectly positioned at regular intervals in the longitudinal direction by the loader 27. All the longitudinal and transverse reinforcements 24 and 28 then rest on the first layer of concrete 36 exiting from the extrusion plate 21 before entering the inter-plate area for bringing and vibrating the concrete in front of the main extrusion plate 4.
  • FIG. 2c shows the second layer of concrete 38 being formed by the main extrusion plate 4.
  • the second layer 38 is extruded and molded above the first layer 36 so as to reach the total thickness H desired for the reinforced concrete slab and, simultaneously, the longitudinal and transverse reinforcements 24 and 28 are embedded between the two layers 36 and 38.
  • the height of the extrusion plate 21 is for example adjusted in such a way so that the height h at which the longitudinal reinforcement 24 is located is approximately equal to half the thickness H of the final reinforced concrete slab.
  • the additional extrusion plate 21 and the auxiliary chassis 26 which supports it have a height significantly lower than the height of the main extrusion plate 4 and of the auxiliary chassis 5.
  • the additional extrusion plate 21 has, in its front part and in its upper part, a wedge shape. This reduced height and this wedge shape allow the excess concrete which is in front of the additional extrusion plate 21 to pass over the latter towards the action zone of the main extrusion table 4. This allows to balance the pressures exerted on the top and on the bottom of the additional extrusion plate 21 and thus gain on the inertia of the structure. This results in a gain in the weight of the material and in the penetration forces into the mass of concrete to be extruded.
  • the sliding formwork machine of the present invention makes it possible to dispense with the spacers which were previously necessary to support the longitudinal reinforcements 24 and which at the same time served as transverse reinforcements, all the longitudinal reinforcements 24, including the lateral reinforcements, can be brought back between the wheels 9 of the auxiliary chassis 8 of the lateral feeding device.
  • This makes it possible to reduce the width of the area occupied by the longitudinal reinforcements 24 at the front of the machine and, consequently, to facilitate the movement of trucks.
  • the lateral feed device 7 shown in FIGS. 1, 4 and 5 has, in its front part 8a_, a width equal to that of the previously known lateral feed devices, it could have an even smaller width.
  • the longitudinal reinforcements 24 would then be brought to the front of the machine over an area of even narrower width and the receiving hopper 11 could then be practically entirely within the width of the area between the two tracks 2.
  • the machine could work on construction sites where the space available is even narrower.
  • the sliding formwork machine of the present invention has two extrusion plates, it allows, with a few modifications which will be described below with reference to Figures 6 to 8, to deposit one on the other two different layers of concrete, with or without reinforcement, whereas previously, it was necessary to use two separate machines working one behind the other to perform this operation.
  • the machine represented in FIGS. 6 and 8 is practically identical to that represented in FIGS. 1, 4 and 5, except that its lateral feeding device 7 comprises another receiving hopper 41, fixed to the front part 8a of the auxiliary chassis 8 and extending laterally outward from the other side thereof, a hopper 42 disposed next to the hopper 12, and another endless belt 43, which extends transversely from a location at the - below the receiving hopper 41 to a location above the hopper 42.
  • the hoppers 12 and 42 could be constituted by a single hopper divided by a longitudinal central wall.
  • the distributor belt 14 is divided into two parts 14a and 14b which extend longitudinally side by side. Part 14 & of the distributor belt extends from a location below the hopper 12 to a location adjacent to the extrusion plate 21, in front of it, while part 14b of the distributor belt s 'extends from a location below the hopper 42 to a location adjacent to the extrusion plate 4, in front thereof.
