The device consists of a tool A having a self-tapping front part 1a and 1b, it is fed at its other end 5 by an injection system of known type 13, allowing the passage of a product under pressure 12 into an axial hole 6 and its diffusion via at least one hole 7 opening out between the self-tapping parts 1a and 1b, and its diffusion in the wood. The device allowing the screwing and unscrewing of the tool A in the wood consists of a mechanical or electromechanical drive element (screw-driving machine with an offset mandrel 8, 9, 11, 14). The method is particularly intended for the anti-parasite treatment of timber for construction.

Description

La présente invention est relative a un nouveau procédé d'injection directe, en profondeur et sous haute préssion, de produits tels que produits de traitements dans des matériaux tels que notament,le bois . Ainsi qu'au dispositif permettant la mise en oeuvre de ce nouveau procédé .  The present invention relates to a new process for direct injection, in depth and under high pressure, of products such as treatment products in materials such as wood. As well as the device allowing the implementation of this new process.

Ce nouveau procedé selon l'invention est caracterlse en ce qu'il permet l'injection sous haute pression des materiaux tels que notament le bois ( 40 a 1 0 barsi cm2 ) ,en une seule operation et par le meme outil par vissage( mecanique ou electro - mecanique )de celui-cl et par le passage a l'interieur meme de cet outil du produit injectable .Le procede selon l'invention est caracterlsé en ce que cet outil est constitue par un axe monobloc creux , pourvu sur sa partie externe avant d'un filetage pointu autotaraudant tel que celui d'une vis a bois d'on type connu . Ce filetage exterieur mal est percé dans sa partie centrale de plusieurs petits trous debouchant dans un trou axial .Ce trou axial étant relie directement a un systeme d'injection haute pression de produit ( raccord tournant et pistolet d'injection d'un type connu ) par un accouplement étan che haute pression ,situe 'a à l'extremite arriere de cet outil . Apres vissage complet dans le bois ,de la partie fileter de cet outil à la profondeur voulue ,le pistolet d'injection permet le passage du produit injectable dans le trou axial de l'outil et à travers les petits trous debouchants situés au centre de la partie filetee,et à sa diffusion sous pression dans les fibres du bois
Ces petits trous ,étant situes au centre de la partie filetee ,la partie arriere de ce filetage empeche tous refoulement du produit injecte , a l'exterieur-du bois
On comprend ansi que l'on puisse injecter sous pression directement des produits dans le bois a l'aide du meme outil et en une seule opération
Une fois l'injection proprement dite terminee , l'outil selon l'invention ainsi que son systeme d'injection , est retirecdu bois par simple devissage (mecanique ou electromecanique ) de celui-ci
Le nouveau dispositif selon l'invention , permetant l'application de ce nouveau procédé d'injection direct selon l'invention,est caracterisé en ce qu'il permet l'injection en profondeur sous haute pression ( 40 à 150 bars I cm2 ), de produits antipasitaires ou autres, dans les fibres de matériaux tels que par exemple, les bois d'assemblages de construction dans le Batiment(charpente, solivages, huisseries .... ect ), ou autres.This new process according to the invention is characterized in that it allows the injection under high pressure of materials such as wood (40 to 10 barsi cm2), in a single operation and by the same tool by screwing (mechanical or electro - mechanical) of it and by the passage inside this tool of the injectable product itself. The method according to the invention is characterized in that this tool is constituted by a hollow monobloc axis, provided on its part external front of a self-tapping pointed thread such as that of a wood screw of known type. This bad external thread is drilled in its central part with several small holes opening into an axial hole. This axial hole being directly connected to a high pressure product injection system (swivel connector and injection gun of a known type) by a high pressure waterproof coupling, located at the rear end of this tool. After complete screwing in the wood, of the threading part of this tool to the desired depth, the injection gun allows the passage of the injectable product in the axial hole of the tool and through the small through holes located in the center of the threaded part, and its diffusion under pressure in the wood fibers
These small holes, being located in the center of the threaded part, the rear part of this thread prevents all discharge of the injected product, outside of the wood
It is therefore understandable that one can inject pressure directly into the wood using the same tool and in a single operation
Once the injection proper is finished, the tool according to the invention as well as its injection system, is removed from the wood by simple unscrewing (mechanical or electromechanical) thereof.
The new device according to the invention, allowing the application of this new direct injection method according to the invention, is characterized in that it allows deep injection under high pressure (40 to 150 bars I cm2), of antiparasitic or other products, in the fibers of materials such as for example, the woods of construction assemblies in the Building (frame, joists, frames .... ect), or others.

L'originalite du dispositif selon invention,réside dans le fait, qu'il permet l'injection en profondeur sous haute pression des produits utilises, en une seule et unique opération. The originality of the device according to the invention lies in the fact that it allows the deep injection under high pressure of the products used, in a single operation.

Actuellement la technique la plus courament employez consiste à percer prealablement d'un trou borgne à un diametre defini, les éléments a traiter ,ensuite à procéder a la mise en place en force dans ces trous , de chevilles plastiques (injecteur plastique courament employé a l'aide d'un marteau et d'une bouterolle,et a proceder enfin ä l'injection proprement dite , à l'aide d'un mate- riel d'injection haute pression d'un systeme courant
Cette technique actuelle demande une main d'oeuvre considerable a cause des différentes phases prealables à l'injection proprement dite .D'autre part, elle nécessite l'emploi obligatoire d'injecteurs plastiques, dont le prix de revient cummulé constitue une charge financière importante pour l'entreprise . En outre ,cette technique actuelle cause un leger affaiblissement supplementaire aux éléments de bois souvent deja alternés par des parasites ou champignons,( percage des trous ).Y compris l'aspect ésthetique du fait que ces injecteurs 'etant à demeure dans le bois,restent visibles à la surface des eléments traités . Currently the most commonly used technique consists of drilling a blind hole to a defined diameter beforehand, the elements to be treated, then proceeding to the forceful installation in these holes, of plastic dowels (plastic injector commonly used in using a hammer and a dowel, and finally proceed to the injection proper, using high pressure injection equipment of a current system
This current technique requires a considerable workforce because of the different phases prior to the injection proper. On the other hand, it requires the compulsory use of plastic injectors, the cost of which cumulated constitutes a significant financial burden for the company . In addition, this current technique causes a slight additional weakening to the elements of wood often already alternated by parasites or fungi, (drilling holes). Including the aesthetic aspect of the fact that these injectors' being permanently in the wood, remain visible on the surface of the treated elements.

Le dispositif selon l'invention permet d'éffectuer l'injection sous pression des ces memes eléments de bois ou autre, en une seule et unique ope'ration
D'or d'une part , une econommie considérable de main d'oeuvre ( de l'ordre de 40 a 60 % ),d'autre part il dispense totalement de l'emploi des injecteurs plastiques ( d'ou une economie financiere considerable ), et ensuite , du fait qu'il altère moins physiquement et esth- etiquement les elements a traiter

This rotary connection thus allows the tool chuck assembly (A) to rotate freely relative to the fixed injection gun.
The device according to the invention is characterized in that the element (B) according to a mechanical variant, consists of a system analogous to a crankshaft, the mandrel of which will be drilled, thus allowing free passage and then the powerful grip between its bit, of tool (A).

Le branchement hydrolique de l'outil(A) sera constitué par un tuyaux blindé solidaire de (A),qui passera à 1' interieur du tube en"U"servant aussi de poignee rotative
Ce tuyaux sera relié à l'autre extremité du tube en"U", dans l'axe du mandrin,à un raccord tounant haute pression relié lui meme au pistolet d'injection qui servira aussi de poigneed'appui .Ce raccord tournant permetra de déssolidariser, dans le sens rotatif avec 360'de liberte tout en restant étanche , le dispositif selon l'invention, du pistolet d'injection
Le principe de fonctionnement du dispositif selon l'invention consiste en ce que 1 'outil(A) étant actionné au contact du bois,par un mouvement rotatif cree par l'action de l'élément (B),la partie filetée (la) de l'outil(A)pique dans le bois,et se visse dans celui-ci jusqu'a noyer com plètement dans la fibre les deux parties filetees(la et lb)
Ensuite ,une pression exercee sur la vachette du pistolet d'injection(13)qui est relie de facon étanche à l'outgitA), par l'intermediaire du raccord tournant haute pression(10) fait pénetrer sous pression le produit(12)qui passe alors à l'intérieur du trou central(6)et se diffuse sous forte pression ( de 40 alto bars/cm2 )à l'1ntérieur de la chambre formee par le diametre decolleté(2)entre les parties filetées (la et lb )par l'lntermediaire des petits trous (7)et se repand à l'interieur des fibres du bois
La deuxième partie fileté4 (Ib)de l'outil(A) interdit tout refoulement de produit injecte, à la surface du bois.The hydraulic connection of the tool (A) will be constituted by an armored tube integral with (A), which will pass inside the "U" tube also serving as a rotary handle.
This pipe will be connected at the other end of the U-shaped tube, in the axis of the mandrel, to a high pressure rotating connection itself connected to the injection gun which will also serve as a support handle. This rotating connection will allow disconnect, in the rotary direction with 360 ′ of freedom while remaining tight, the device according to the invention, from the injection gun
The operating principle of the device according to the invention consists in that the tool (A) being actuated in contact with the wood, by a rotary movement created by the action of the element (B), the threaded part (la) of the tool (A) sticks into the wood, and screws into it until completely drowning in the fiber the two threaded parts (la and lb)
Then, a pressure exerted on the cow of the injection gun (13) which is tightly connected to the outgitA), by means of the high pressure rotary connector (10) causes the product (12) to penetrate under pressure. then passes inside the central hole (6) and diffuses under high pressure (from 40 viola bars / cm2) inside the chamber formed by the neck diameter (2) between the threaded parts (la and lb) through the small holes (7) and spreads inside the wood fibers
The second threaded part4 (Ib) of the tool (A) prohibits any delivery of injected product to the surface of the wood.

Ensuite,une fois l'injection terminee, une action en mouvement rotatif en sens inverse de la première, par l'action de l'élément (B) permet le devissage de l'élément (A >
Le dispositif selon l'invention est caracterise en ce que l'outil (A) sera un outil interchangeable , et qu'a chaque type d'elements à traiter ( pannes , chevrons ,huisseries ...) dont la profondeur et l'epaisseur à traiter sera differente , pourra corespondre un outil (A) dont le diamètre des parties filetees (la et lb) ansi que celui des diamètres lisses(2 et 4 ) se situera entre 5 et 20 milEmet- res,dont le pas des filetages (la et lb) se situera entre 1 et 7 milimètres , et dont la longueur des parties ( la , lb , 2 , 4 et de la longueur totale de l'outil (A) ) pourra varier en fonction de la profondeur des elements a traiter .Then, once the injection is finished, an action in rotary movement in the opposite direction to the first, by the action of the element (B) allows the element (A>
The device according to the invention is characterized in that the tool (A) will be an interchangeable tool, and that each type of element to be treated (purlins, rafters, frames ...) including the depth and the thickness to be treated will be different, may correspond to a tool (A) whose diameter of the threaded parts (la and lb) as well as that of the smooth diameters (2 and 4) will be between 5 and 20 millimeters, including the thread pitch ( la and lb) will be between 1 and 7 millimeters, and the length of the parts (la, lb, 2, 4 and the total length of the tool (A)) may vary depending on the depth of the elements to be treated .
