Description

FIXING DEVICE WITH SLIDING CONDUITS IN PARTICULAR FOR POSTS. - - - - - - - - - - - - - - - - - - - - -

The invention relates to the equipment of posts stressed by horizontal or oblique loads.

The known devices have the major drawback of being made by two or more identical or different elements welded between them, which does not make them reliable when they are placed in the ground using a ram because a risk of weld rupture subsist

According to known devices, in general, whenever there is a desire to enclose a given area, appropriately spaced posts, most often metallic, placed in the ground using diced concrete, which support for example a wire mesh. This will more often be the case, along certain expressways, such as motorways, railways, etc. or to limit prohibited access, forest areas, plantations, etc ...

The known devices, although effective, are particularly off-putting and costly in terms of their implementation.

Indeed, each load take-up post requires the development after earthwork of a hole in which the post is positioned and then permanently fixed by pouring a concrete, most often forming a dice, When it is necessary to install very long palisades or barriers sometimes covering several hundred kilometers, the difficulties are most numerous and unexpected, often linked to the consistency of the soles used. In addition, such an essentially artisanal installation is necessarily of a particularly high cost and of a particularly slow implementation.

These difficulties can be very widely accentuated when the installation of such fences is carried out in underprivileged countries where cement and water are lacking and where despite everything, a need to fence a specific area is necessary for economic or security reasons,

By way of example, which can be very extensively supplemented, the installation of elements such as poles is carried out in most sectors: airports, motorways (fences and security barriers) railways , delimitation of plantations, forestry operations, telephone, electric poles, road signs, terminals, urban shelters, advertising signs, in the latter case and in order to comply with the regulations in force and certain safety standards, these signs must be able withstand winds of the order of 180 lia / hour, which requires very complex and most often unsightly winding of said panels, In urban areas, the installation of certain elements such as panels, urban shelters , etc ... is made more difficult by the consistency of the receiving soils, most often concreted or asphalted on cement gravel. This requires relatively large earthmoving means, binding in the final implementation, in the immediate environment and which, therefore, are necessarily reflected in the particularly high and long construction costs.

According to certain known means for delimiting polygons or fixing palisades, vertical tubes often inserted into the ground are then used, at their lower end with an anchorage to protect them from being torn away, however these means have never really given satisfaction and we had to use stabilizers to replace these anchoring means.

The stabilizing members also known, are composed either of horizontal metal plates having folded corners or sides and a central bore to receive the central post, the entire plate then to be buried entirely in the ground; either of two trapezoidal metal plates and each having two parallel slots so that each plate can be engaged one in the other so as to form a central part describing a square or a parallelogram and serving to surround the post to be fixed , These stabilizing means, although interesting, do not allow resumption of significant loads, require a particular implementation and have only one purpose, moderately stabilize a vertical element, such as a post, The aim of the present invention is to overcome the drawbacks of known devices and allows the production of a fixing device with sliding sheaths for fixing, without sealing, elements such as posts in a simple, quick, safe and inexpensive manner, thereby making it possible to to realize in eminently advantageous conditions, very long lengths of installation of fence or other.

To this end, the invention relates to a fixing device with sliding sheaths for fixing without sealing elements such as posts, characterized in that it is constituted by two or more identical metallic or other elements forming a sliding wing and elastic sheath. , symmetrical, asymmetrical, sliding with respect to one another, without having to be joined to one another by welding, embedding, stapling or the like, with or without folds over the upper projection of the lateral part of the wing.

The invention is shown by way of nonlimiting example, in the appended drawings in which: FIG. 1a represents two elements forming slides,

FIG. 1b is an alternative embodiment with three elements forming slides, FIG. 1c represents four elements placed in the ground and provided with a load take-up post, the arrows representing all the lines of force acting on each composite element of the fixing device,

FIG. 1d is an alternative embodiment of the fixing device using four slide elements,

FIG. 1e is another alternative embodiment of the wing element forming a slide,

FIG. 2a represents an advertising pole put in place using the fixing device according to the invention,

FIGS. 2b, 2c, 2d, 2e represent, without limitation, a series of applications of the fixing device according to the invention,

- Figures 3a to 3d schematically illustrate the different phases of the method of implementing the fixing device according to the invention, - Figures 3e schematically illustrate the different phases of the process of implementing the fixing device according to the invention on a hard support.

According to a characteristic of the invention, as shown in Figures 1a to 1d, the fastening device 1 comprises two or more identical elements made of metal or other, having the shape of a wing 2 provided with a slide 3 in part central so that each element can slide thanks to their respective slide one in the other or one in the other, without having to be joined by welding, embedding or other, which makes it possible to obtain a device for robust fastening fast and economical, interesting as shown in Figure 2a most sectors, such as advertising, agriculture, industries, etc ...

The upper part of the lateral projection of the wing 2 may include a fold 4 provided for example with a tapped orifice 5 for immobilization allowing attachment any element above the ground, such as cleanliness terminal, bus shelters, etc.

According to another characteristic of the invention, the part forming a slideway 3 of each element, is obtained by folding, profiling, stretching, electroforming or the like, so as to constitute a central element forming a sleeve 6 intended to receive a load take-up post. 7 of appropriate section, The lower part of the wing element

2 with slide, constitutes a penetration and sectioning tool,

According to another characteristic of the invention, as shown in FIG. 1c, each element forming a sliding wing 2 comprises a vertical lateral projection forming one or more right or oblique angles 8 relative to the slide of the post 7 so as to create a or several force polygons, resistant to the reaction of a horizontal or oblique traction by the mass of its volume of the soil requested in compression and tearing,

The vertical lateral projection of the wing 2 can be produced as required, so as to have a flat, wavy, striated, rib, or even perforated profile for certain particular uses.

According to another characteristic of the invention, as shown in FIG. 1e, the vertical lateral projecting part of the wing 2 with slide 3 has a rib profile representing one or more axes of penetration and the lower ends of these ribs are made of so as to present a tip 1 6.

Similarly, the lower part or penetration contact line of the wing 2 with slide, can be produced horizontally, inclined or in any intermediate form, such as concave, convex or angular.

This penetration contact line constitutes a tool, and for this purpose, the lower part of the wing 2 with slide can be sharpened, serrated or recharged. managed to obtain a high performance tool according to the range of uses sought.

According to another characteristic of the invention, the lower part 9 of the wing element 2 with slide forming a sheath 6 can be produced horizontally or obliquely.

- A horizontal execution avoids the slight gyration caused by the oblique point of the wing element 2 representing a thread.

An oblique embodiment has the advantage of causing on the wing 2 a deformation by a slight movement of gyration making seek the center of gravity of the mass of the volume of compressed earth on a line, no longer horizontal, but oblique in depth.

According to another characteristic of the invention, each wing element 2 is combined by sliding so as to constitute a sheath 6 allowing the establishment of a post 7 for load recovery, This sheath 6 is elastic both axially as roundabout, which is of considerable importance for the implementation of the device according to the invention. This axial and gyratory elasticity allows almost immediate adjustments each time they are required, which saves considerable time.

The section of the sheath 6 of the wing element 2 constituted by the slide 3 obtained for example by folding, can be in a nonlimiting manner, represented by any geometrical figure, such as round, square, rectangular, octagonal, triangular or other and this section can be sized large or small depending on the desired use. Thus, the section will be reduced for a load take-up post for trellising while it will be more important for the installation for example of a telephone post.

According to another characteristic of the invention, as shown in Figures 3a to 3d, relates to a method and means for implementing the device fixing sleeve with sliding sheath, for fixing, without sealing, elements such as posts,

To this end, one or more elements 1 forming a sliding wing are put into the ground, using means adapted for this purpose. Preferably as illustrated in FIG. 3a, a hydraulic unit 11 of small size, very handy, with a power of the order of 140 bars or an electric generator will be used.

A tool also suitable, consisting of a hydraulic mixer 12, a striking rate of the order of 1300 strokes / minute, provided with a driving guide 13, allows direct installation of the elements 1 wings in a medium mechanical soil, without rocky or hard consistency such as topsoil with or without stone, clay soil, marl, chalk, coated, asphalt, serious cement, stabilized earth, etc ...

The driving guide 13 is produced in a shape and a section which varies according to the section of the element 1 sliding wing to be driven into the ground.

The fitting operation, as illustrated in FIGS. 3b to 3d of the element 1 sliding wing, is carried out by prior positioning of the sheath or sheath 6 on the guide 13 for driving in the hydraulic mixer 12.

After pressing in, the beater and tool assembly 12 and 13 are released by sliding so as to leave in the ground, the wing element 1 which remains trapped in it. The fixing device is then operational and ready to receive by introduction into the sheath 6, a load take-up post 7.

According to another characteristic of the method and of the implementing means in accordance with the invention, the insertion of a sliding wing element 1 of large section, in a medium mechanical soil, is carried out as shown in FIGS. 3a to 3d thanks to the realization of a pilot hole using a drill bit not shown tee, in line with the post a. set up, so as to destructure by this front hole the central core. Once the pilot hole has been made, an element 1 forming a sliding sheath is positioned on the driving guide 13 of the hydraulic mixer 12, the sheath guide assembly is then pushed into the ground using the hydraulic mixer 12, then released then the beater and tool assembly 12 and 13 by sliding, so as to leave in the ground the element 1 wing which remains trapped in it.

According to another characteristic of this process, the insertion of a sheath element 17 on a hard support such as rock, sandstone, granite, concrete, cement, etc. as shown in Figures 3e, is effected by the making a pilot hole using a drill bit 14 and an impression made using a tool 18 with carbide tip, of adequate section. ι Then the sheath 17 is positioned forming a slide on the driving guide 13 of the hydraulic mixer 12, the sheath guide assembly is forcibly pushed into the ground, using the hydraulic mixer 12, then the assembly is released. beater and tool 12 and 13 by sliding so as to leave the sheath element 17 in the ground, which is then ready to receive a load-taking post.

The invention generally applies to most sectors, such as advertising, public works, agriculture, industries, industrial buildings, dwellings, etc.
