Description

The present invention relates to a device for limiting or even eliminating all sources of accelerated corrosion at the feet of posts, posts, markers, posts related to road signs, streetcar, streetlights and the like, fixedly positioned on sidewalks or pedestrian paths. .

To date, to my knowledge, there is no existing device of this type of protection against external corrosion due to external attacks of all types of liquids with main corrosive tendency creating migrating and deteriorating infiltrations of these signals at the base level. The device according to the invention overcomes these disadvantages. 11 has in fact according to a first characteristic an elastomer rubber ring E.P.D.M. (ethylene-propylene-diene-monomer), anti ozone and ultraviolet, extruded or molded from an appropriate shore ensuring a perfect connection between the bottom of emergent structures of all forms a priori conventional, adapting to all types of soils in which the latter would be implanted and whose sealing and perfect connection would be ensured, both by the form of the invention and by means of two-component glues or other appropriate. According to particular embodiments: - The device, curved triangular shape and sloping from top to bottom allows outward flow of the base to protect against corrosion of all types of liquids (canine urine in principle, detergents used for cleaning, rainwater and runoff, powerful jets of cleaning sprays by trucks in the city or agglomeration, and other sources of corrosive nature). it is in this case to avoid all types of sneaky infiltration - which, if they are not visible in evidence - undermine the submerged supports or causing rust and weakening in the short term! This phenomenon of active corrosion, apparent at first sight on the surface by the traces of rust, must see its coefficient obligatorily multiplied in the zones situated in wet basement and confined without any aeration. - Different rings of standard models can be made by extrusion directly in the factory, namely the square gray or green markers (8.5 x 8.5 cm) of sides placed on the sidewalks, as well as the round posts of 10 cm. 0 gray or bald gray, round gray and low gray posts measuring 22 cm from 0, the base of the various signposts supports placed along the tramway tracks as well as at all intersections and other pole locations related to the road signs (0 6 cm) as well as those of street lamps (or street lights) of various 0 lighting placed along the passage of the tracks of the tramway (011.3 cm. and 36), pedestrian and disabled safety barriers, motorcycles , and other media to protect in order to prolong their life and reduce their frequency of replacement. The aforementioned colors and currently applied are indicative to better visualize the existing and may vary from one agglomeration or city to another, the purpose of the device of the invention is primarily to protect the base elements above listed or other of different diameters or shapes; Some poles are 0 superior and octagonal can also be treated by the method defined as follows. - 2

- A variant according to the invention consists in the linear manufacture of the compact elastomeric rubber profile (EPDM). The latter being cut to non-standardized dimentions and ends rabbits and polymerized using contact adhesives, bi-components or cyanocrylates of strong adhesion.

This would actually be the case to consider for the base of some streetlights of the Tramway which have a collar wider width about 1 m. of the ground, as well as for other structures that do not allow simple dressing of the preformed ring which is the object of the object of the invention. The base cateners supports and cable supports also.

The sealing of the ring now located at the base of the posts, posts and posts to be protected will be made by strong-setting glues, and the bonding to the ground by gel or dual-component glues, resins, bitumens, for the purpose of adhere perfectly on all supports, even when they are implanted on soils comprising a slight slope or peatonal passage in pelletized rubber or other sol of special character. In some cases, an adjustable circle of lost material of the desired diameter of 1. or 1.5 cm in height may be affixed to the ground in order to avoid unsightly and costly surpluses and overflows, to eliminate unnecessary sagging and to achieve Substantial savings of products and present a finished job !.

Depending on the quantities to be treated, special molds of varying sizes can be made to avoid this additional strapping operation. The invention therefore makes it possible to make the existing existing installations benefit by protecting them in advance from an inevitable corrosion and also preserve the oldest ones, for a price which is certainly lower than that of the replacement and thus to realize substantial savings in terms of short, long and medium term compared to a premature change, following the time of application. The accompanying drawings illustrate the invention: - Figure 1 shows in section the device of the invention. FIG. 2 represents the adhesive surfaces of the device of the invention to the various emergent structures to be protected. According to a second variant, the protective device which is the subject of the invention may be completed by a strapping of 0, which is greater and variable (high 1 / 1.5 cm), retaining the excess of chosen adhesive products thus ensuring more resistant floor sealing. This technique will find especially its reason for large diameters !. With reference to the sketches 1 and 2, the device comprises in its upper part a primary sealing lip (1) bonded and perfectly contiguous 10 mm. height, an intermediate portion with toric pins (2), a second lower lip glued (3) 15 mm. width, as well as a horizontal surface grooved (4) of contact with the different types of soils through the aforementioned binders (gel glues, two-component glues, resins .... - Before any application of the ring of the device of the invention on a painted support, it will be necessary to sand lightly with glass paper and degrease before final establishment.

For an oxidized or rusted, but unbored substrate, more vigorous sanding will be required, or even sandblasting, followed by a rust remover / fixer and degreasing prior to application of the sealant claimed by the invention.

By way of non-limiting example the protective ring will have dimensions of the order of 65 mm. for the height and 45mm for the width on the ground, with a thickness of 5 mm at each end of the curved triangle of the base in contact with the ground. as well as its upper part to protect vertical runoff from possible canines, rainfalls or other! The form of the invention being that of a triangle whose diagonal is concave, sealing tapes made according to the model of the invention can be made to meet all forms of various applications, of any nature and lengths can be applied according to specific specifications to meet all types of sealing required.

The device according to the invention is particularly intended for the protection of the visible base of immersed structures in order to prevent their corrosion in the first place of external appearance, but especially to avoid invisible and proliferating internal corrosion due to infiltration. and constant moisture held in the soil, thereby decreasing their shelf life, conservation and efficiency over time and requiring regular replacement, for lack of regular maintenance, tedious and expensive .. All this could be avoided by a simple joint !, such as the subject and the perspective of the invention. A flange adapting perfectly to all the desired diameters, dimensions and figures of the parts to be protected in case of paint maintenance or other types of interventions could be provided to protect the seal so that the latter can be preserved. partly its physical properties as well as its intact aesthetic appearance in relation to the posts, terminals, and all emerging bases protected by the principle of the invention.
