Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the formwork elements are used in the manufacture of precast concrete usually arranged on vibrating tables in the concrete plants, that of using the compression for the purpose of shaping of the formwork elements are poured concrete.
  • the vibrating table usually consists of a supporting structure Steel beams and a steel plate forming the table top. to Simplification of the formwork removal and lifting of the hardened Concrete parts are often tiltable with their table top set up.
  • the vibrating tables are usually equipped with an excitation device in the form of arranged over the table top Equipped with external vibrators, which the supporting structure from the Steel beams and the table top can vibrate.
  • the external vibrators have an electric motor, pneumatic or hydraulic driven unbalances and are appropriately in attached to the supporting structure of the vibrating table.
  • EP-A-0 251 150 shows a device for receiving formwork elements for the production of components made of concrete with a load-bearing structural structure and an associated one, for compacting the still plastic concrete Flat formwork skin that can be set in vibration by means of a vibrating device. There are cushioning between the formwork skin and the structural structure Spacers inserted. The vibrating device engages bypassing the Spacers on the formwork skin.
  • the object of the invention is therefore to create a device which on the one hand has a uniform input of vibration energy ensures the liquid concrete and with high power density the compression time is reduced to a minimum, but on the other hand during the compression the formation of structure-borne noise in the Scarf and support structure, especially in the static structure, avoided and as far as possible the transition from structure-borne sound to airborne sound reduced.
  • the excitation device intervenes bypassing this Lanyards directly or indirectly on the formwork skin so that any sound transmission between the formwork skin and the structural structure is significantly reduced.
  • connection means are preferably between the formwork skin and the static structure as an intermediate layer arranged between them from body ball and vibration isolating Executed material (claim 3), and engages the excitation device through this intermediate layer to the formwork skin (Fig. 6).
  • the device according to FIGS. 1 and 2 has a static structure from steel beams 1a and one arranged on the beams, in Compacting operation horizontal plate 1b, which usually made of steel, but also of other high-quality materials Strength can be formed, and with through openings 1c is provided.
  • the static structure 1 can be one Act simple, undamped type vibrating table, in the table top 1b, the through openings 1c later have been cut into it.
  • the upper part of the static structure with the plate 1b can, as in Fig. 1 indicated, compared to a lower one firmly anchored to the ground Part 1d can be pivotally connected about a pivot axis 1e, handling the finished concrete component, in particular to facilitate its removal from the formwork.
  • An intermediate layer 2 is placed on the static structure 1 has through openings 2c, which are in the assembled Condition of the entire device with the openings 1c of the plate 1b of the static structure.
  • the intermediate layer has, as in Fig. 2 and 3 indicated, a honeycomb structure.
  • the properties of which are further below to be explained in more detail lies in the assembled state of the Device on a formwork skin 3, which is usually made of steel, but also from other materials with steel-like properties, e.g. made of glass fiber reinforced hard plastic can.
  • a formwork skin 3 which is usually made of steel, but also from other materials with steel-like properties, e.g. made of glass fiber reinforced hard plastic can.
  • On this formlining 3 are through the openings 1c Plate 1b and the openings 2c over the entire surface
  • the formwork 3 is distributed in the form of vibration exciters attached by external vibrators 4.
  • the intermediate layer 2 is a viscoelastic layer which Formwork skin 3 is supported from below without any other supporting structure and has a strength that withstands the mean surface pressure.
  • This viscoelastic layer significantly reduces the Transfer from the external vibrators 4 and the formlining 3 Structure-borne noise on the static structure below 1a, 1b, which is otherwise one of the main causes of noise emissions in the vicinity of the vibrating table or the receiving device is.
  • the intermediate layer favors the equalization and amplification of the vibration caused by the external vibrators 4 the formwork skin 3 above to stimulate the concrete compaction.
  • the viscoelastic intermediate layer 2 preferably consists of a gradient material that is in relative proximity to the formlining 3 is relatively soft and therefore mechanical properties which has the propagation of vibrations in it Favor formlining 3, and that on the of the static structure on the other hand, damping and plastic properties has the structure-borne noise transmission to the static structure 1a, 1b to be largely avoided.
  • These characteristics of Intermediate layer can be achieved in different ways e.g. in that different suitable raw materials together are connected or composite materials are used whose mechanical properties meet the requirements.
  • the desired properties of the intermediate layer can e.g. due to different additives in one another Height sections of an otherwise identical according to FIG. so monolithic base material existing intermediate layer become.
  • an intermediate layer with gradient properties 3 is to obtain the intermediate layer 2 to be built up from several layers one on top of the other. 3, three layers are provided. each of the three layers of the intermediate layer 2 lying one above the other depending on what the percentage of air spaces in it is how thick the layer is and what elastic properties the material used for them has different elastic and sound-absorbing properties, whereby here too the Formwork skin 3 facing top layer 2a relatively soft elastic in contrast, the middle layer has a larger modulus of elasticity and the bottom, the static structure 1a, 1b facing Layer mainly sound-absorbing and plastic properties which has primarily the structure-borne noise transmission prevent or at least significantly reduce the static structure.
  • the external vibrators 4 are preferably each located in them miniaturized frequency converters operated (not shown), which in connection with the external vibrators 4 a controlled system for the speed and thus for the force-excited vibration frequency exhibit. A remote control can then use it the frequency of the individual external vibrators is independent of each other can be adjusted, which makes the vibration profile even the formlining 3 is very accommodating.
  • the vibration transmission elements 5 are preferably designed in such a way that that this from them, the formwork skin 3 and the external vibrators 4 existing vibration system at the chosen, desired Excitation frequency comes into resonance, with which a strengthening of the Vibration excitation is achieved.
  • This strengthening of the Vibration excitation is achieved by optimizing the dimensions of the material and achieved the tuning of the frequencies so that the directly excited by the external vibrators 4, over the intermediate layer 3 formwork skin, e.g. a thickness of 5mm with a surface of several square meters, in resonance vibrations is offset, but by the special design the connection of the external vibrators to the formwork body 3 it is ensured via the vibration transmission elements 5 that structure-borne noise not or only very strongly damped on the existing structural structure 1a, 1b is transferred.
  • the invention is also particularly suitable for its application on existing vibrating tables that have no or only insufficient ones Have soundproofing, because with these vibrating tables besides the easy to dismantle the external vibrators from their previous positions only the existing table top with openings provided for performing the vibration transmission elements 5 must be to the existing vibrating table as a load-bearing structural structure to be able to use for the device according to the invention.
