DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to new cellular structures for producing sustaining walls.
BACKGROUND ART
In my Canadian Patent 1,186,516, I disclose a cellular structure which comprises two straight embedding walls joined by a curved wall which forms the front of the cellular structure. In this type of module, the lateral pressure of the mass retained between the walls of the cellular structure maintains these walls stationary. Indeed, the lateral pressure exerted by the retained mass anchors the walls which retain this mass.
DISCLOSURE OF INVENTION
It is an aim of the present invention to provide new cellular structures for sustaining walls which use materials available on the market.
It is also an aim of the present invention to provide a cellular structure which is of great simplicity as much at the level of the manufacture of the structural elements which constitute the cellular structure as at the level of the carrying into effect thereof.
It is a further aim of the present invention to provide an economical cellular structure.
It is a still further aim of the present invention to provide a cellular structure for which the masonry of the face thereof may be carried out with different finishes.
According to the preceding aims, an advantageous embodiment of the invention includes a cellular structure for sustaining an embankment which comprises a substantially vertical facing structure and a pair of substantially vertical embedding structures made of lattices. Each embedding structure is adapted to be mounted to a respective vertical edge of the facing structure. The facing structure is adapted to define a facade of the cellular structure. The embedding structures are adapted to extend in the embankment.
Another advantageous embodiment of the invention includes a cellular structure for sustaining an embankment which comprises a substantially vertical facing structure and an embedding structure formed at least of one stirrup. The stirrup is adapted for connecting each of its two extremities to a respective vertical edge of the facing structure. The stirrup forms a U-shaped structure adapted to extend in a substantially horizontal way in the embankment. The facing structure is adapted to define a facade of the cellular structure.
Another advantageous embodiment of the invention includes a rigid cellular structure for sustaining an embankment which comprises at least one concrete foundation element and one facing element made of prefabricated concrete adapted to be fixed in a substantially vertical way to the foundation element with first connection means. A pair of embedding elements made of prefabricated concrete are adapted to be fixed in a substantially vertical way to the foundation element with second connection means.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view illustrating a series of cellular structures in accordance with a first embodiment of the present invention, wherein the facing and embedding structures are made of lattices;
FIG. 2 is a perspective view illustrating a second series of cellular structures in accordance with a second embodiment of the present invention, wherein the facing structures are lattices and the embedding structures are stirrups;
FIG. 3 is a top plan view illustrating the filling of the cellular structures of FIGS. 1 and 2 by way of a sunk framework, and also illustrating a facade of cast concrete;
FIG. 4 is a top plan view similar to FIG. 3, but wherein the facade is a masonry made of concrete blocks;
FIG. 5 is a perspective view similar to FIG. 1, but wherein the facing structure is constituted of independent bars;
FIG. 6 is a perspective view similar to FIG. 2, but wherein the facing structure is constituted of independent bars for receiving architectural concrete blocks;
FIG. 7 is a horizontal cross-section illustrating the structures described in FIGS. 5 and 6 and adapted with a facade made of concrete blocks;
FIG. 7a is a cross-section taken along lines 7a--7a of FIG. 7 and illustrating an assembly of the concrete block
