FR2651258A1 - Omega-shaped construction element intended mainly for supporting earth masses - Google Patents

Abstract

- The element, characterised by its OMEGA shape, is produced from vibrated concrete, which is possibly tinted throughout. The stack of the elements laid down alternately on each row, and associated with a filling material makes it possible to produce gravity walls. The element consists of: - two struts (1) extended by two legs (3) located orthogonally, the oblique shape of which increases the filler/concrete friction, the legs constituting two anchoring points in the filler. - A front face (2) holding the filler material inside the element and providing an aesthetic appearance for the wall. - A partial bottom (4) on the front part of the element opposing the vertical compacting of filler inside the wall. - The rear part is hollowed out (6) for the incorporation of reinforced concrete posts. - Two channels (5) cut in the legs allowing concrete, geotextile, or geomeshwork blocks to be fastened mechanically. The main uses are: - support, sound-attenuation walls, buttresses for passages, walls, window boxes.

Description

- ELEMENT GEOMEGA
The present invention relates to a multifunction element for the support of land and for the construction of various works.

Land support is traditionally carried out using elements of variable shape which, stacked, allow the raising of walls. However, these elements do not allow the realization of other more elaborate works and present a certain number of disadvantages as for their stability in original configurations different from the elevation of simple retaining walls.

It was therefore a question of finding an element having a shape allowing it to adapt to new configurations while preserving qualities of stability without defect.

According to a first characteristic, the element takes the form of OMEGA. This form has the advantage of offering two parts or curved legs and therefore a double base or seat which provides better stability.

These two legs, according to a second characteristic, end in two feet which have a triple function: - Provide an anchoring or harpoon effect in the ground horizontally.

- Ensure a land grab vertically thanks to its projecting parts.

- Receive a location or engraving to allow 3a realization of work.

- Represent a large seat surface at the end of the element.

According to a third characteristic, the interior of the element is partially closed by a bottom, thus forming a soil retention tank which, by its weight, ensures stability.

In this background is made a light for the fixing of element involved in the realization of certain tupe of work.

According to a fourth characteristic, the element consists of a raised front part which ensures: - The front face of the wall, variable according to particular embodiments.

- The seat of the other stacked elements - The stop of the upper elements.

 (Figure l) shows in perspective the original shape of the element.

 k figure 2) represents a plan view in which the engravings and the light are notably apparent (Fig. 3 and 4). represents the front part of the element or visible part, side opposite to the embankment in its curved or rounded variant.

According to the characteristics of the OMEGA element, the elevation of walls is obtained by successive stacking of elements arranged in staggered rows. The laying of each pile or rows is followed by a filling of compacted fill. This technique results in the elevation of so-called modular walls.

The originality of this element consists: - In the possibility, with the same element achievable in industrial quantity:
To build retaining walls or weight or gravity walls: 1) Inclination can vary from 50 to 90 2t Vegetable, that is to say that according to (Figure 5) in the
front formed by the external face of the stacked elements
find occupied surfaces Far the earth or embankment and
that vegetation can develop there.

(. Figure 6) is another re-representation from the
variant offeredue by the rounded facade.

(. figure 9) represents the alignment of the elements for

(- figure 10) represents the positioning of the elements
to get a concave wall.

get a convex wall.

3) To make straight, inclined, concave or
convex.

With the same element and according to the characteristics offered
by the light arranged in the bottom of the element, it is
possible to realize:
4) vertical walls which cannot be vegetated, i.e.
full, incorporating a plate secured to the element to
using a metal or resin pin. In this case none
earth backfill is only visible on the facade according to (. figure 1-2.)
5) The element can allow the realization of a wall to
variable thickness thanks to the addition of a block of
reinforcement whose mechanical anchoring is ensured by
engravings made in the element. (figure 13 A - 13 B)
represent this characteristic.

6) .t figure 14 A) and (. Figure 14 B) represent the
characteristic that the element can also be
secured to geotextile sheets which are fabrics
high resistance at the back of the interior side wall. This
device for increasing stability.

7) According to a new characteristic, thanks to the shape
internal and external of the element jamb it is possible
to integrate a vertical structure of reinforced concrete or post.

This vertical structure increases the load
allowed in pressure and shear, which will be useful
in the various jobs of the OMEGA element.

This vertical structure being cast in the same shape
of the OMEGA element which constitutes a lost formwork. The (figure 1.5) represents this characteristic.

The OMEGA element, for information, is made of standard concrete
B 30 vibrated if necessary tinted in the mass.

(fig'-l5: A) represents a road underpass
consists of vertical elements with plate and tablecloth
integrated geotextile as well as a post structure
incorporated. (figure i5B) represents the underpass seen
in plan.

The general design of the element represents a
outcome in the search for the support surface
optimal upper elements; because this stacked element is
subjected mainly to compression efrorts
concentrated on the bearing surface.

The larger this area, the less the risk of breakage
are important.

The present invention relating to the grouping on a single element of the ten (10) following characteristics, and the
realization of multiple works or multiple applications.

1 Large bearing surface allowing a
wall (fruit) tilt from 50 to 90 without compromising the
stability by total or partial use of this surface
support.

2 Consequently of the 1 optimization of the resistance to
compression by the choice of the shape of the element offering a
excellent surface / volume ratio.

3 Element allowing the realization of straight, concave walls
or convex.

 4 Element allowing the realization of green walls.

5 Element allowing the realization of solid vertical walls
by incorporating plaques.

6 Element designed for the production of thick walls
variable by mechanical attachment of reinforcement block
7 Element designed for the mechanical attachment of
geotextile intended to reinforce stability.

8 Shape of the element allowing the incorporation of a
vertical structure in reinforced concrete with lost formwork.

9 Shape of the element's legs which allow
stable nesting of elements for the realization of walls
double sided.

10 Element allowing the realization of solid walls by installation
contiguous vertical or inclined elements.

The OMEGA or GECMEGA element is particularly intended for public procurement of road stabilization, embankments, construction of bridges or structures.

By way of nonlimiting example, the basic element will have dimensions 50X60X25 Cm.
