Abstract

The present invention concerns a method and an arrangement for processing surplus concrete slurry, comprising a frame (3) and a number of shuttering forms (4) for concrete slurry, which can be removed from the frame (3), which frame (3) is suitable to be transported by means of a motorized vehicle provided with a trailer, such as a truck or a tractor, wherein the frame is provided with support elements (5a,5b) for positioning the shuttering forms (4) on the frame and with coupling elements (6) for coupling and uncoupling of the frame to the trailer.

Description

  • The present invention concerns a method and an arrangement for processing surplus concrete slurry.
  • Surplus concrete slurry originates from an excess concrete slurry which needs to be prepared to be sure to finish a concrete work on a building site within a certain time period. Because of the manufactured overproduction per concrete mixer or concrete work, a considerable amount of concrete per concrete mixing plant is produced daily, the processing possibilities of which usually mean an environmental-economical loss. Processing usually means pouring this concrete slurry into so-called slabs or the upgrading of the concrete slurry in the concrete mixing plant into more suitable building elements. Usually, pouring of this surplus is the most economical solution for a concrete mixing plant, but this is surely detrimental from an environmental point of view. The object of the present invention is to provide an arrangement and a method for upgrading and processing of this surplus concrete slurry, which resolves, at least partly the aforementioned disadvantages.
  • To this end, in a first aspect, the invention provides an arrangement comprising a frame and a number of shuttering forms for concrete slurry, which can be removed from the frame, which frame is suitable to be transported by means of a motorized vehicle provided with a trailer, such as a truck or a tractor, wherein the frame is provided with support elements for positioning the shuttering forms on the frame and with coupling elements for coupling and uncoupling the frame to the trailer.
  • The use of such a frame, for example having the form of a carriage, provides the logistic advantage that such an arrangement can be temporarily left alone on a concrete construction site. Hence, the invention provides the advantage that on a concrete construction site an excess concrete shuttering forms on the frame is provided. With each surplus concrete slurry per concrete mixer, this surplus is transported in the shuttering forms.
  • Gradually, in the course of the activities, these shuttering forms are filled up, each time with a surplus of concrete slurry. For each frame a number of shuttering forms may be provided, enough for the daily amount, to receive the excess concrete slurry per concrete work. The invention further provides the logistic advantage that the excess concrete slurry does not need to be returned to the concrete mixing plant, but may be processed on the spot at the concrete construction site. When the daily activities and the filling up of the shuttering forms has ended, the concrete slurry is left to cure at least partially, preferably for 6 to 12 hours. Subsequently, the device is retrieved generally the next morning, whereby optionally an empty arrangement is provided again for the surplus concrete slurry of a subsequent time period.
  • In a second aspect, the invention provides a shuttering form suitable to be transported in series on the common frame. Shuttering forms are generally known. The shuttering form according to the present invention is characterized in that the bottom side of the bottom of the shuttering form is provided with support profiles which are preferably U-shaped and which extend in the transverse direction of the shuttering form.
  • Preferably, the shuttering form is provided with a coating, such as a concrete form oil. Preferably, the shuttering form comprises one trapezoid-shaped groove and a corresponding trapezoid-shaped tongue to improve the stackability. Preferably, the tongue/groove is provided in the middle of the side walls of the shuttering form.
  • In a third aspect, the invention provides a method for processing a curable material, for example surplus concrete slurry, comprising the steps of:
    • providing a number of shuttering forms on a transportable frame,
    • transporting the frame provided with the shuttering forms to a surplus concrete slurry site,
    • filling the shuttering forms with the surplus concrete slurry at the surplus concrete slurry site,
    • optionally post-processing the concrete slurry in the shuttering forms, by vibration or other compaction methods,
    • at least partially curing the concrete slurry in the shuttering forms,
    • retrieving and transporting the frame provided with the at least partially filled shuttering forms to a further processing site,
    • removing the shuttering forms from the frame,
    • dismantling the obtained building elements and
    • cleaning and subsequently, optionally treating again the empty shuttering forms which are to be placed on the frame again, such that the steps mentioned above may be conducted again.
  • Some embodiments of the invention are elucidated by means of the figures wherein :
    • Figure 1 shows a perspective view of an arrangement according to the invention,
    • Figure 2 shows a schematic sectional view of a preferred embodiment of the shuttering form according to the invention,
    • Figure 3 shows a face view of the shuttering form according to the invention and
    • Figure 4 shows a perspective view of the obtained building element from a preferred embodiment of the shuttering form according to the invention.
  • An arrangement 1 according to the invention is composed of a frame 3 provided with a number of shuttering forms 4 for surplus concrete slurry. The shuttering forms are removably provided on the frame 3. To this end, the frame 3 is provided with support elements 5 onto which the shuttering forms 4 rest. The frame 3 has the shape of an open carriage and is at the front provided with coupling elements 6 having the form of a hook means 6a, to be placed in a simple manner on a trailer using a crane jib or a winch. To this end, the frame may also advantageously be provided at the back end with one or more rolling or sliding means 17. Such means are known from the container industry, for example containers for construction rubble. The frame 3 comprises essentially two longitudinally extending and mutually parallel beams or profiles 7 provided with pairs of parallel cross beams or profiles 5a, 5b. These cross beams 5 are suitable for the support of the shuttering forms 4. For a good support of the shuttering forms 4 on the cross beams 5, one, and preferably two profiles 9a, 9b are provided on the bottom 8 of the shuttering form 4, which match in shape and size the support elements 5a, 5b of the frame 3. The support profiles 9 are also suitable to be transported using the forks of a lift fork truck. To this end, they may be designed as a U-shaped profile. The shuttering forms 4 are movable in the transversal direction of the frame 3. Once positioned on the frame 3, they may be optionally better secured to the frame using securing systems 14.
  • The shuttering forms 4 comprise at least one tongue 10 and one corresponding groove 11. Hence, the obtained concrete elements 15 are mutually stackable. Preferably, the tongue/groove arrangement is trapezoid-shaped. Every suitable dimension may be provided, for example 60/60/120 cm or 40/40/120 cm or 80/80/120 cm. The shuttering forms 4 are open at the top and provided with five walls 12 coupled to the bottom 8 by means of hinges 13. The shuttering form may be provided with a clamping means 15 for mutually tightening the side walls 12.
