Definitions

  • the present invention relates to what is claimed in the preamble and is therefore concerned with the battery formwork of precast concrete parts.
  • Battery circuit arrangements are known. They already serve to be able to economically manufacture a large number of precast concrete parts on construction sites in a short time. This affects e.g. elongated precast concrete parts such as Beams, semi-finished beams, purlins and supports of general building construction, which are installed in large numbers for each building without any significant change to each other. However, this also includes ram piles for the foundation formation and / or noise barrier elements.
  • a battery formwork arrangement can be filled with concrete from above and rotated after the precast concrete parts have hardened, so that the concrete parts then fall down after they are released from the chamber.
  • the precast concrete parts are typically removed from the formwork chamber with power, i.e. by means of actuators.
  • the aim should be to achieve a production technology that is also suitable for others on a large scale on or on construction sites
  • a site size of more than 100 m 3 of precast volume is typically relevant here.
  • the object of this invention is to provide something new for commercial use.
  • the present invention thus proposes, in a first basic concept, a battery formwork arrangement with at least one formwork chamber and an actuator for supporting precast concrete parts at a location at which it is provided that the actuator acts as an upwardly acting actuator and the formwork chamber or arrangement is designed to remove the formwork.
  • the present invention is therefore based on the knowledge that the savings from bulky or wide prefabricated parts by stripping several parts at the same time with just one hand movement is not as great as with many small parts, but nevertheless allows considerable savings with suitable series production, unless it is rotated like in State of the art, * but a different approach is realized.
  • an actuator can also be used to act against gravity and additionally serves to overcome the adhesive forces, that is to say only to release it from the shape, but not to remove it from it.
  • the formwork chamber will then be open at the top, i.e. it will not be turned into a position with the side open at the bottom.
  • an operating mode which consists of this can be preferred not to turn the formwork, but to push the concrete parts out of the formwork by means of particularly strong actuators for stripping so that a hoist can lift the beam without having to pull the static friction and the adhesive forces to the formwork wall.
  • the dead weight does not have a relieving effect, but rather a strain on the actuator. It is astonishing here that there is at most a slight component deformation even in the case of actuators with a small area, so that there is no risk of destruction of the finished part.
  • a particularly preferred variant can be provided with an element that is height-adjustable and pressure-transmitting, for example, by means of a thread
  • the actuators can be arranged on a base frame that is connected to a battery formwork substructure in a tensile manner.
  • combinations of threads and sleeves can be used to attach the stamp.
  • the actuators will typically act hydraulically. This allows the use of a robust technology that is suitable for use on construction sites and in which, in particular, pressure equalization between different actuators is achieved when working with several actuators without having to undertake considerable control efforts. In addition, the work safety required even at high hydraulic pressures can be easily achieved. Special measures for occupational safety are preferred in hydraulics, e.g. to prevent hydraulic oil from spurting out even over longer strokes under a typical water column of 1000 to 7000 m. Encapsulation of lines, counterbalance valves, flow limiters, etc. are representative here. - _.
  • the base frame is particularly torsion-proof to enable it to be set up on an uneven surface without any formwork chamber deformation.
  • a multifunction device used in the production of concrete parts is preferably used for the invention supplemented with a lifting device.
  • This lifting device then preferably lifts several reinforcement cages at the same time, for example. from a pre-arranged shelf in which the iron maker can either prefabricate or also deliver prefabricated and store it in a defined manner so that the subsequent reinforcement installation can then be automated or accelerated.
  • the multifunction device is self-propelled, in this case it is also preferred to create an off-road capability so that the surroundings do not have to be specially prepared for use. You get a self-propelled, all-terrain gantry crane with multi-functional quality.
  • a tower crane covers very large construction site areas with effective radii of typically 30 to 55 m. It is also particularly suitable, since the usual approach of the mobile cranes is no longer necessary, for example for smaller assembly files, which typically do not fill up a whole day and therefore require the start-up and shutdown efforts of mobile cranes.
  • the prefabricated concrete parts should therefore preferably be moved with a maximum of two stops from manufacture to the place of installation, regardless of the type of crane used. , ... -
  • a plurality of shuttering chambers are provided in a battery shuttering arrangement, in particular at least two shuttering chambers parallel in the longitudinal direction, in order to produce a plurality of identical or similar components at the same time.
  • the battery formwork arrangement of the present invention is preferably used for repetitive structures and the formwork chamber mern make it possible to either produce several identical components or components that differ in height and / or length, but not in width. This is preferred because the width variation requires different side wall layers and is therefore more complex to implement.
  • the formwork chambers can be formed with a variable geometry, which means that it is possible to choose a system battery formwork arrangement that works from the construction site
  • displaceable side and / or wall elements can be provided and / or inserts or floor formwork can be provided which are suitable for producing the desired elements.
  • Such walls are present.
  • These displaceable side and / or wall elements can be provided in particular on a base frame or base frame, specifically by means of detachable means.
  • a modular formwork system is obtained which can be removed from the top and reinforced from above.
  • the walls can be moved between several cycles, but not for demoulding.
  • the battery formwork arrangement now proposed is particularly preferred when wider components are to be produced, in particular those with a width of more than 40 cm and more preferably more than 50 cm.
  • the arrangement is currently particularly economical if a volume of at least 0.5 m 3 , preferably from Im 3 is reached and is then even more economical than the known battery rotary formwork.
  • the formwork can be made much easier in any case if the vertical walls of the finished parts have an inclination of about 1:20. If the incline is over 1:40, the formwork is not made much easier; if it is below 1:10, there is no further relief, but an unhelpful change in shape due to walls that are too flat does. The provision of a fall facilitates the stripping, so that movement of the walls for the purpose of stripping is no longer necessary.
  • the wall position only if one or more other precast concrete parts are to be manufactured, that is to say to leave the wall stationary and / or unchanged during the actual production cycle.
  • the actuator which is preferably provided for overcoming adhesive forces between the walls or floor and the precast concrete part, is omitted and instead the higher forces during stripping, which are to be overcome by means of the lifting arrangement, are permitted.
  • Protection is therefore also generally claimed for a method for producing an elongated precast concrete part, it being provided that near the construction site, in particular at a simply equipped production site, where appropriate and preferably also under the open sky, a slack reinforcement is placed in a variable form and with concrete is shed. It was recognized here that the rotary shell production of the invention preferred for railway sleepers can also be used for other, in particular elongated precast concrete parts such as ram piles, purlins and the like.
  • the elongated prefabricated concrete parts can be manufactured with the same shape and / or in a different shape from each other end to end and / or long side to long side in a battery mold.
  • a formwork form which has a stable, preferably also torsionally rigid base module, on which a plurality of formwork chambers are provided in an independent form.
  • These formwork chambers are preferably assembled modularly, which enables the production of smaller series even in conventional building construction with the arrangement described. In this way, purlins, beams or long supporting pieces can be manufactured in order to to preserve filigree repetitive structures.
  • the formwork elements can be combined in various ways, which allows the flexible pre-assembly of a form, for example in a warehouse for component formwork modules, after which it is possible to manufacture exactly the required, different parts from one another at the construction site. It should be pointed out that in the individual formwork modules which are attached to a base module or underframe, floors which can be displaced in height in particular can be used instead of known insert boxes. Preferred elements are all elements particularly known from frame formwork.
  • a particularly preferred effect of arranging displaceable, stable and load-bearing side walls is that the main surface of the expensive formwork work has been inserted into a simple, flexible and construction site-compatible system.
  • a coupling of several battery formworks in their length is preferably made possible, which reduces the incorrect assignment due to part lengths which are unfavorable compared to the battery length (example: 3 instead of only 2 6.00 m long parts per lane can now fit in 2 coupled 10 long batteries).
  • the mold can be cleared from the top in a particularly preferred variant, which also ensures that the mold is completely filled.
