Definitions

  • the present invention refers, as its title indicates, to improvements introduced into machines for the continuous manufacture of concrete parts, of the type which include a chassis movable on rails which define a track on which are placed tensioned wires forming the reinforcement of the concrete parts to be obtained, this chassis being supported by an upper hopper for receiving the concrete, a fixed hopper for supplying a vibrator mold, a front retaining mold, a vibrator mold provided cores for forming concrete parts and a posterior mold, also provided with cores, for refining the parts; the improvements of the invention relate to the means of traction of the machine, the attachments and the sizing of the vibrator mold and of the refiner mold, the fixing of the cores of the vibrator mold, the lateral closing of the molds, the guidance and the traction of the hopper configuration, the hopper configuration and the actuation of an anterior wire guide.
  • Patent of Invention 428477 referring to a "Process for the continuous manufacture of beams, posts, plates and the like in concrete", an installation is described consisting of rails anchored to the ground, between which are placed longitudinally a series of cables tensed which form armor on which the concrete is poured, by means of a machine provided with the relevant hoppers and lower molds, so that, moving forward, the machine forms the beams or the reinforced elements.
  • the machine described in this patent already envisages the use of three molds: a front mold, a central mold or vibrator, provided with cores or walls which define the section of the part to be obtained and a posterior mold or refiner; it also envisages the use of two hoppers: a fixed one, which pours the concrete onto the armor formed by the cables and the other mobile or overload, which feeds the previous one.
  • the cores which form and refine the concrete parts are respectively integral with the vibratory and the refining mold and, therefore, if one wishes to change the type of part to be formed, it is necessary to completely release these molds and to raise the machine, these remaining deposited on the ground, which makes it particularly difficult to center and assemble the new molds.
  • the vibrator mold has a large capacity, which causes a significant problem since when the machine At the end of the runway, throw the concrete that remains inside to prevent it from setting.
  • the refining mold presents the problem that the concrete which forms the part, on leaving the mold, spreads, which makes it difficult to obtain a certain precision in the dimensions of the parts obtained.
  • the rolling means of the machine are hidden under the bench, which makes it difficult for the operator of the crane bridge to correctly position these rolling means on the rails when the track machine is changed. , with the resulting loss of time.
  • the upper hopper is the cause of retentions in the concrete, which makes it difficult to unload, by the fact that it only moves by a single push cylinder which acts on its central area; in the fixed hopper which feeds the vibrator mold, concrete retains also occur, determined, on the one hand, by its configuration, and on the other, by the vibrations transmitted to it by the vibrator mold, which determines its turn the preliminary compaction of the concrete inside this fixed hopper.
  • the chassis rolling means are composed of wheels mounted on three axes, two front and one rear, and drive wheels which are placed at the rear end of the machine, mounted on a balance which is actuated by a hydraulic cylinder, which makes it possible to vary the height of these driving wheels, by placing them in an operational position or in a non-operational position.
  • Both the wheels of the anterior fixed axle and the drive wheels are in visible positions, which facilitates the centered positioning of the machine on the rails.
  • the lateral zones of the chassis, comprised between the rolling means have their lower end on a higher plane. as the wheels to prevent the deposition and setting of the concrete thereon, facilitating access to the closing side rubbers.
  • the central mold or vibrator has supports adjustable in height with respect to this mold, which are fixed to the chassis of the machine with the interposition of the corresponding elastic elements, intended to prevent the transmission of vibration from the mold to the chassis.
  • the machine has at its front end a folding wire guide, which is actuated automatically by means of a hydraulic cylinder, ensuring its correct positioning relative to the part to be formed by the machine; as an option, this wire guide can be adjustable both vertically and laterally.
  • Another of the improvements included in the invention consists in that the cores of the central mold are fixed thereto, with a possibility of extraction, preferably by means of screwed elements, which makes it possible to vary the profile of the parts. to form, changing only the cores and, therefore, it is not necessary to change the entire mold, as happens with known machines.
  • the invention provides that the vibrator mold has a length less than that of known machines and that the cores which are placed inside have in their front region a wedge-shaped portion, which causes that there is no no concrete retainers inside, the quantity of concrete retained by this mold when the machine reaches the end of the runway is minimal.
  • This vibrator mold is supplied, as on known machines, by a fixed mold placed between the upper hopper and this mold, with the particularity that the upper hopper moves by the action of the two hydraulic cylinders which act on the sides of this, preventing their interference in the discharge of concrete to the fixed hopper; the other particularity is that the fixed hopper has three inclined sides, which converge towards the lower zone, while the posterior side is vertical, which makes it possible to reduce the capacity of the hopper and to facilitate the descent of the concrete towards the vibrator mold .
  • the lateral closing of the molds, to prevent the concrete from coming out from below the sides is produced by rubber profiles which are pressed in an oblique direction by a metal angle integral with the manual actuation cylinders.
  • the refining mold is mounted on a projecting portion of the chassis and is fixed there by its upper zone, which makes it possible to extract this mold from the upper zone of the machine, keeping it stationary.
  • This refining mold has at its rear end a concrete relaxation box to counteract the expansion of the latter at the outlet of the machine, by obtaining greater precision in the dimensioning of the parts to be obtained; this relaxation box has on its upper surface longitudinal sections of a small thickness for the exit of the air entrained by the concrete, preventing that cannot occur defects on the profile of the part to be obtained.
  • the nuclei housed at the interior has a slight reduction in section in order to obtain this relaxation effect of the concrete.
  • the machine for the continuous production of concrete parts has a frame (1), on which is mounted by the upper part an upper hopper (2), by which the load of the concrete and which is responsible for feeding the fixed hopper (3).
  • the upper hopper (2) is actuated by two hydraulic cylinders (2a) which act on the sides of the latter preventing them from being a hindrance during the unloading of the concrete to the fixed hopper (3).
  • the fixed hopper (3) has its inclined and converging sides towards the lower zone, with the exception of the rear side (3a) which is vertical, in order to obtain a reduction in its capacity and facilitate the descent of the concrete towards its lower zone .
  • a retaining mold (4) On the chassis (1) are mounted on the lower level a retaining mold (4), a vibrator mold (5) which is fed by the hopper (3) and a refiner mold (6).
  • the retaining mold (4) placed in the anterior zone of the machine comprises a trap door (7) with vertical displacement, responsible for preventing the advancement of the concrete deposited in the vibrator mold (5) and a foldable trap door (8) ;
  • the hatch (7) is actuated by a hydraulic cylinder (7a) placed vertically in the central zone thereof and its movement is guided by the set of levers (9), while the hatch (8) is actuated by a cylinder hydraulic (8a).
