Abstract
Calcareous kerbstone appearance restoration involves playing jet of flame produced by oxyacetylene burner over surface
Description
La présente invention a pour objet un procédé pour la réfection et l'entretien de revêtements, en roche calcaire. I1 est fréquent d'utiliser des roches calcaires taillées ou travaillées comme revêtement dans la construction, que se soient des revêtements horizontaux, bancs, margelles, bordures ou des revêtements verticaux, façades, encadrements de fenêtres ou portes, angles d'immeuble, etc.
Après un certain nombre d'années, cinq à dix ans, ces roches se salissent et ont un aspect noir peu plaisant. On est donc conduit à retailler ces roches pour leur redonner leur aspect d'origine. Ces opérations de retaillage sont très longues et pénibles et souvent nécessite la dépose des pierres ou bordures, le travail ne pouvant pas être exécuté sur place.
La présente invention tente de remédier à ces inconvénients par un procédé qui se caractérise par le fait que la ou les surfaces apparentes au moins de la roche sont chauffées par un jet de flamme, pour faire éclater sa couche superficielle et lui redonner ainsi son aspect de roche taillée d'origine.
Le présent procédé qui consiste à faire éclater à la flamme une pellicule de roche sur la face visible, à rafraîchir peut être appliqué à la réfection ou à l'entretien périodique de revêtement en roche calcaire verticaux ou horizontaux.
L'aspect des surfaces de roche ainsi taillées est très semblable à une roche taillée à la broche mais il est évident que ce ravallement s'effectue beaucoup plus rapidement qu'un retaillage manuel à la broche.
Un autre avantage de ce procédé réside dans le fait que le flammage peut s'effectuer sur place, même sans déplacer ou desceller les blocs de roche, ce qui entraîne également une économie de temps et de mains d'oeuvre considérable.
Une application particulière de ce procédé est la réfection des bordures de trottoir qui peut se faire soit après avoir déposé les blocs de roche, généralement du granit, soit directement sur place en protégeant le revêtement de la route pour ne pas le faire fondre.
Pour mettre en oeuvre ce procédé on fait passer très près de la surface de la roche à nettoyer un brûleur oxy-acétylénique diffusant une flamme à environ 3000 degré centigrade et qui fait éclater des particules de roche. On dirige de préférence le brûleur obliquement par rapport au fil de la roche.
Ce procédé permet d'obtenir une surface rafraîchie d'une grande régularité tout en conservant l'aspect rustique du travail manuel à la broche.
REVENDICATIONS
I. Procédé pour la réfection et l'entretien de revêtements en roche calcaire, caractérisé par le fait que la ou les surfaces apparentes au moins de la roche sont chauffées par un jet de flamme, pour faire éclater sa couche superficielle et lui redonner ainsi son aspect de roche taillée d'origine.
11. Application du procédé selon la revendication I, à la réfection des bordures de trottoir.
SOUS-REVENDICATIONS
1. Procédé selon la revendication I, caractérisé par le fait qu'on dépose des blocs de roche à traiter avant leur traitement thermique.
2. Procédé selon la revendication I, caractérisé par le fait qu'on effectue le traitement thermique des roches lorsque celles-ci occupent leur place dans la construction.
3. Procédé selon la sous-revendication 1 ou la sous-revendication 2, caractérisé par le fait que la flamme est diffusée par un brûleur oxy-acéthylénique.

The present invention relates to a process for the repair and maintenance of coatings made of limestone. It is common to use cut or worked limestone rocks as coating in construction, whether they are horizontal coverings, benches, copings, borders or vertical coverings, facades, window or door frames, building corners, etc.
After a number of years, five to ten years, these rocks get dirty and have an unpleasant black appearance. We are therefore led to re-cut these rocks to restore them to their original appearance. These re-cutting operations are very long and painful and often require the removal of stones or borders, the work not being able to be carried out on site.
The present invention attempts to remedy these drawbacks by a method which is characterized by the fact that at least the visible surface (s) of the rock are heated by a jet of flame, in order to burst its surface layer and thus restore its appearance. original cut rock.
The present process which consists in bursting with a flame a film of rock on the visible face, to be refreshed, can be applied to the repair or to the periodic maintenance of vertical or horizontal limestone rock coating.
The appearance of the rock surfaces thus cut is very similar to a rock cut with a spindle, but it is obvious that this resurfacing takes place much more quickly than a manual re-cutting with a spindle.
Another advantage of this process lies in the fact that the flaming can be carried out on site, even without moving or unsealing the blocks of rock, which also results in a considerable saving in time and manpower.
A particular application of this process is the repair of sidewalk edges which can be done either after depositing the rock blocks, generally granite, or directly on site by protecting the road surface so as not to melt it.
To carry out this process, an oxy-acetylene burner is passed very close to the surface of the rock to be cleaned, diffusing a flame at approximately 3000 degrees centigrade and which bursts rock particles. The burner is preferably directed obliquely with respect to the grain of the rock.
This process makes it possible to obtain a refreshed surface of great regularity while maintaining the rustic aspect of manual spindle work.
CLAIMS
I. Process for the repair and maintenance of limestone rock coverings, characterized by the fact that at least the visible surface (s) of the rock are heated by a jet of flame, to burst its surface layer and thus give it back its aspect of cut rock of origin.
11. Application of the method according to claim I, to the repair of curbs.
SUB-CLAIMS
1. Method according to claim I, characterized in that blocks of rock to be treated are deposited before their heat treatment.
2. Method according to claim I, characterized in that the heat treatment of the rocks is carried out when the latter occupy their place in the construction.
3. Method according to sub-claim 1 or sub-claim 2, characterized in that the flame is diffused by an oxy-acetylene burner.
