Definitions

  • the invention relates to a spatial structure built up of a support body to be placed on a support surface; a reinforcing layer to be arranged over the support body; and a curable substance to be poured over the reinforcing layer.
  • the invention also relates to a method for constructing a spatial structure, comprising the steps of:
  • Such a spatial structure is generally known. It is frequently used in the construction industry for constructing structures having a convex (synclastic) or a cylindrical shape. When a reinforcing layer (or reinforcing net) arranged over an inflatable construction is used, however, only shapes comprising a circle or a segment of a circle can be realised. Accordingly, only a limited number of shapes can be realised with the current, known structures, and consequently it is the object of the invention to provide a more versatile spatial structure which makes it possible to realise other shapes as well.
  • the spatial structure is characterised in that the support body is made up of several support elements, and in that the reinforcing layer comprises a net structure, which has been pre-tensioned to a specific surface contour, with the inflatable support elements giving the reinforcing layer its shape.
  • At least one support element is furthermore configured as a membrane that can be inflated with a medium.
  • inflatable support elements or forms
  • pre-tensioned reinforcing layer configured as a net structure arranged thereover makes it possible to realise various types of shapes.
  • synclastic convex
  • cylindrical shapes but also anticlastic or concave shapes.
  • the spatial structure is characterised in that the pre-tensioned surface contour comprises at least the minimum surface area between one or several surface points and/or one or several surface lines.
  • the reinforcing layer is given its shape by being tensioned.
  • the shape of the net will in that case form the minimum surface area between a number of given elements.
  • the shape of the mesh in tensioned condition is different from said minimum surface shape on account of
  • Said pre-tensioned surface contour may furthermore be influenced in that according to the invention one or more lines of tension are created over the pre-tensioned surface contour.
  • said at least one line of tension can create a deformation in the reinforcing layer towards or away from the inflatable form, so that this also makes it possible to design the spatial structure to comprise various concave or convex shapes.
  • the reinforcing layer may be provided with one or more tensionable cables, which may or may not be incorporated in the reinforcing layer, whilst in another embodiment, with which various concave or convex shapes can be realised, the reinforcing layer is tensionably attached to the support surface.
  • the curable substance is a grout, for example concrete, but the curable substance may also be a synthetic material, for example a polymer resin.
  • the curable substance is ice.
  • the invention also relates to a method for constructing a spatial structure, which method is according to the invention characterised by the further step of forming a surface contour counteracting the shape of the inflated support body in the reinforcing layer configured as a net structure prior to the execution of step iii).
  • numeral 10 indicates a spatial structure according to a first embodiment, which is built up of a reinforcing layer 11 to be arranged over an inflatable form 12 that can be placed on a support surface 1.
  • the inflatable support body 12 is made up of several, three in this embodiment, inflatable support elements 12a-12c.
  • the inflatable support elements 12a-12c may have identical dimensions but also mutually different dimensions in order to thus realise random, irregular shapes of the spatial structure.
  • the reinforcing layer 11, which is provided with a net structure is tensioned over the inflatable support body 12 and fastened down near the ends or edges 11a-11c. In this way it is possible to realise not only a convex (synclastic) shape at the location where the reinforcing layer 11 is arranged over the inflatable support elements 12a and 12c, but also a concave (anticlastic) shape, as is indicated at 11 b in figure 1.
  • a self-supporting spatial structure By subsequently applying a curable substance, such as a grout, a polymer resin or ice, to the pre-tensioned net structure 11, a self-supporting spatial structure can be realised, after which the various inflatable support elements 12a-12c can be deflated and be removed from the spatial structure.
  • a curable substance such as a grout, a polymer resin or ice
  • FIG. 2 A different shape of a spatial structure is shown in figure 2, in which the inflatable support body 12 is made up of four inflatable support elements 12a-12d, so that a more complex spatial structure can be realised by fastening down the tensioned reinforcing layer 11 at the edges 11a-11c.
  • the spatial structure comprises a number of convex (synclastic) portions as well as a few concave (anticlastic) portions 11 b.
  • FIG. 1 A similar embodiment comprising four inflatable support elements 12a-12d is disclosed in figure 3.
  • Figure 4 discloses yet another, more symmetric spatial structure made up of three inflatable support elements 12a-12c to obtain a convex shape alternated with a concave (anticlastic) shape 11 b-11 b'.
  • figures 5 and 6 show embodiments in which the reinforcing layer in the form of a net structure is deformed in outward direction by a pillar 20 (figure 5) or a post 20 (figure 6).
  • the shape of the spatial structure of the illustrated embodiments is realised by the shapes of the support elements on the one hand and by fastening down the tensioned reinforcing layer at the edges 11 a-11 b on the other hand, it is also possible to influence the shapes by creating lines of tension in the reinforcing layer 11, for example by providing the reinforcing layer with cables 20, which are tensioned somehow or other, for example pulled upwards or downwards, as is shown in figure 7.
