Definitions

  • the present invention relates to a method and a device for producing hollow bodies, in particular containers made of concrete.
  • Containers for storing bulk goods and liquids, especially large containers, are mostly made of steel or plastic, less often of concrete. While steel has to be protected against rust, which involves costs, plastics, at least as far as surface quality is concerned, are much more durable. Because of their low strength, plastics require high material strength and are becoming increasingly expensive due to the shortage of petroleum.
  • the aim of the invention is to propose a method for producing containers made of concrete, which avoids the difficulties mentioned and is characterized by a high speed and simplicity, and the device required for this.
  • the shape-changing shell consists of an elastic organic material, preferably based on isoprene; such as natural or synthetic rubber, rubber and the like.
  • inflatable sleeves can be made from rubber or other isoprene-like materials that take on a preferred shape when inflated depending on the pressure intensity. So you can inflate dallons, which have a round shape at a certain low internal pressure, which changes into a very oval shape when the pressure is increased.
  • the targeted change in shape in the event of pressure increase is planned in the production of balloons which serve as toys, namely the thickness and nature of the base material are selected locally so that the desired final shape is obtained when a reference pressure is exceeded inside the balloon.
  • the basic idea of the invention is to make use of this technology in order to find simple and easy-to-use concrete molds that can be reused many times in the course of a coating process.
  • the volume of the shape-changing shell is increased by pneumatically changing the internal pressure.
  • an empirically determined inuc pressure can be set to convert the shell into the desired shape, specifically as the next pressure controlled by means of a pressure relief valve.
  • the coating with colloidal concrete can also be carried out in stages and the newly applied concrete layers can be provided with one or more reinforcements, preferably in the form of steel wire fibers or fabrics, between individual stages.
  • the device for carrying out the method according to the invention is characterized in that a shape-changing shell (1) or (2) made of elastic organic material has a collar (10) which is inserted between two concentric carrying and clamping rings (11), the inner one King carries a cover (15) into which a nozzle (20) opens, which is connected via a hose (21) to a pump (21), while the outer ring is attached to a suspension frame (0).
  • This device which is easy to handle and maintain, also has the advantage that it requires minimal space.
  • the largest space is taken up by the finished containers, while the shape-changing shells, regardless of the caliber, also take up little space in larger quantities, unlike conventional concrete molds.
  • FIG. 1 shows a non-limiting embodiment of the device according to the invention.
  • the shape-changing shell (1) or (2) is attached to a support or suspension frame (0).
  • the latter is shown on the left in the image in the pressure-free state (la) or (2a), while on the right in the image the same shell is shown under pressure in its operating mode (1b) or (2b).
  • the bowl (1) represents the basic shape for an essentially cylindrical, tapering container, which can be used, for example, for storing bulk goods such as grain and the like. can serve, while the shell (2) is used to produce a pear-shaped container, for example. As an underground oil container in question.
  • the bowl is provided with a collar (10) which is inserted in a clamping and support ring (11) with a cover (15).
  • the internal pressure rises from the atmospheric pressure (po) to the empirically determined operating pressure (px), which is maintained by means of the pressure relief valve (12) and at which the shell has the desired shape.
  • the lifting platform (40) is raised, the container is picked up, the pressure release valve (13) is opened and the lifting platform (40) is lowered.
  • the container is then removed and the same process can start again.
  • the pressure-generating medium is generally air. However, it is not unreasonable, especially for the production of containers of smaller caliber, to provide liquids as a pressure-generating medium, provided that the shell used has the properties required for this.
  • the containers produced according to the invention can be used practically without any special finishing measures.
  • a water-repellent additive to the colloidal concrete, at least in the exposed layers.
  • Alkali silicates such as water glass or similar products customary on the market can be considered as such.
  • the lost protective cover which in this case can only be described as lost in relation to the protection of the shape-changing shell.
  • the protective cover can therefore remain inside the container and can be attached to the inner wall with a resin cover if necessary.
  • the weight ratios must be kept in mind when carrying out the method according to the invention for producing more or less thick-walled containers. If you reach a certain concrete layer thickness, you may consider interrupting the spraying process so that the form is not unduly stressed. Accordingly, the existing casing will be allowed to harden, be pulled out and subsequently thickened, or at least the bottom of the container will be finished in order to enable a support for supporting the container and then produce the desired wall thickness.
