Definitions

  • the invention relates to construction materials and more particularly the manufacture of slabs or copings used in particular for swimming pools.
  • the slabs are obtained in the press from a concrete plant where a high manufacturing cost.
  • the product obtained is therefore very heavy, which poses real problems for transport, considerably increasing costs.
  • the slabs or copings obtained are quite fragile, so that at the time of their handling, storage, or transport, significant risks of scratches and crumbling may appear. Indeed, no means of protection is provided.
  • the invention is therefore set to remedy these drawbacks in a simple and effective manner.
  • the problem which the invention proposes to solve is to avoid damaging the slabs or curbs when stacking the elements acting as molds.
  • a peripheral edge is formed projecting from the hollow internal impression, in a horizontal plane, to constitute a support rim; external vertical wings are formed projecting from the periphery, under said peripheral rim, said wings being able to bear on the peripheral rim of another element arranged in superposition.
  • the problem posed is solved in that the vertical wings extend beyond the bottom of the element thus ensuring good air circulation between the stacked elements to solve the problem of drying the product.
  • Another problem which the invention proposes to solve is that of being able to produce a hanging drop directly at the time of the manufacture of the coping;
  • the element has, in a manner parallel to one of the edges of the hollow internal imprint, an insert capable of producing, after demolding, a hanging drop, in particular in the case of a coping.
  • the bottom of the volume is horizontal or inclined, the vertical wings being the same length so that the squared supporting rim remains in a horizontal plane.
  • Another problem which the invention proposes to solve is to obtain a coping, the various edges of which, in particular the edges situated beneath the said coping, are largely rounded to avoid any risk of snagging and possible injury.
  • a part of the mold, in particular at the level of the opening of the hollow imprint has, directly or in an attached manner, at least one flexible and profiled tongue situated at the level of the edges to present the rounded part considered.
  • the element according to the invention therefore acts as a lost mold by constituting a protective shell for the transport, storage and handling of the slabs or copings while avoiding, under these conditions, damaging the product. It also appears that immediately after the molding operation as such, it is possible to handle, store and / or transport the product, without having to wait for the latter to be completely dry.
  • Figure 1 is a perspective view of an embodiment of the element according to the invention shaped for the manufacture of a coping.
  • Figure 2 is a cross-sectional view taken along line 2-2 of Figure 1 after pouring the concrete for the production of the coping.
  • Figure 3 is a perspective view of the curb obtained.
  • Figure 4 is a cross-sectional view of the shaped element for the production of a slab.
  • Figure 5 is a sectional view showing the stacking of several elements according to the invention.
  • the element according to the invention designated as a whole by (1) is shaped to delimit a hollow internal footprint (1a) corresponding to the dimensions and shapes of the slab with the coping to be obtained after pouring the concrete.
  • the element (1) is obtained by injection of a plastic material and constitutes a lost mold.
  • a peripheral rim (1b) is formed projecting from the internal cavity (1a) to form a horizontal support rim.
  • this rim (1b) are formed overflowing the periphery of the element (1), vertical wings (1c) capable of bearing on the peripheral rim of another superimposed element (Figure 5).
  • the vertical wings (1c) project from the bottom of the element (1) so as to leave remaining, after stacking of several elements (1) (FIG. 5), a separation interval (e) to allow the free circulation of air to improve concrete drying.
  • the internal imprint (1a) of the element (1) is generally quadrangular in particular rectangular or square.
  • the edges or edges of the imprint (1a) are rounded.
  • the lateral edges (1a1) and (1a2) of the imprint (1a) have a different thickness to correspond to the profile in section of said coping to be obtained. It therefore appears that the bottom of the imprint (1a) is inclined relative to the vertical wings (1c) which are of the same length so that the squared support rim remains in a horizontal plane ( Figure 2). Obviously, in the case where we want to obtain a slab, the footprint (1a) is thick constant with a horizontal bottom relative to the support plane delimited by the vertical wings.
  • the element (1) has, in a parallel manner to one of the edges of the recess (1a), an insert ( 2) in the form, for example, of a rod of cylindrical section capable of producing, after demolding, a hanging drop (G).
  • the insert (2) is preferably mounted removably for demolding
  • the element (1) as defined by the characteristics of the invention makes it possible to produce slabs and copings in a particularly simple, rapid and efficient manner. For this, it suffices to pour, automatically or manually, inside the hollow cavity (1a), the necessary quantity of concrete (B).
  • the element (1) thus furnished can be handled immediately with a view to its storage or transport, the slab or coping obtained being perfectly protected by said element (1).
  • the vertical wings are supported during the vertical stacking of several elements on the horizontal peripheral rim (1b) thus avoiding any contact with the concrete which is not yet completely dry. The separation interval between each of the elements thus superimposed facilitates the drying of the slab or coping obtained.
  • This tongue is formed directly or in a manner related to the level of one of the external edges of the indentation (1a) ( Figure 1).
