      Reinforced joint.
    OBJECT OF THE INVENTION
    The present specification defines a reinforced joint intended for the serial connection of pipes, preferably for glued pipes. and therefore the invention is intended for the civil works sector and more specifically for hydraulic pipeline assembly work.
    By means of the use of this reinforced joint, the joint area between the pipes is perfectly sealed, for which, prior to the connection of a pipe in the adjacent one, the joint is introduced in a simple and manual way in a groove of one of the pipes, and the correct tightness is achieved because said gasket has a flexibility similar to plastic gaskets which allows its installation manually, just as a gasket is obtained that has a high internal resistance only within reach of metal joints.
    BACKGROUND
    The joints for the connection of pipes are elements commonly known to the general public. They are generally referred to as gaskets, and are components that serve to ensure the tightness of the joint between two pipes. These joints have their reason for existence in the irregularity of the faces of the pipes, which means that by means of a joint it is possible to correct the possible failures that could exist in the manufacture of said pipes, as in certain pipes there is a difference in diameter that allows the coupling of one pipe with the next. Therefore, these elements save money in the machining of the joint surfaces because it does not require that the coupling between two pipes be completely accurate since said joints correct said possible failures and ensure the tightness of the hydraulic conduction, as well as allowing pipe typologies are developed that allow direct serial coupling between them, ensuring the tightness in said joint area.
    Depending on the type of union of the pipes, different types of joints arise, which have been subject to evolution and improvements over time. Specifically, the present invention is directed to glued pipes, that is, tubes that have a slight widening at one of their ends with a groove for housing joints that make the joint between the two pipes airtight when the next pipe is introduced.
    These tubes can be made of different materials, such as plastic, metal or cement, just as the uses can be diverse, such as transportation of drinking water, irrigation, recycled water or sanitation. In this regard, the two usual methods of installing joints for this type of driving, which is the automatic method with special tools and the manual method, should be highlighted first. Basically, the automatic method with special tools is a method used with steel seals or rings, known in the industrial field as a system "rieberquot ;, in which the pipe is heated, and with the help of special tools the gasket is introduced inside the tube and it adheres to the annular shape of the joint. On the other hand, the manual method is the conventional one for joints or plastic rings, and consists of bending the joint exerting a manual force such that the joint can be introduced into the glued tube, and once it is inside it stops exert said force and the gasket returns to its annular configuration and fits into the groove.
    It is important to say that while the metal or steel joints are elements that have not undergone any variation with respect to their annular and flat configuration, the plastic joints have been subject to different improvements. There has been evolution in the outer joints between pipes, such as the one defined in US4842305, or the one defined in ES2411468, which details an improved pipe clamp, although this type of outer joint is not optimal for the type of glued tubes. However, there has also been a sensitive evolution in the internal seals, in which it can be taken from conventional plastic and elastic seals, such as the one defined in register ES I 00 1991, in which an annular gasket of plastic material that is introduced into the groove enabled in the glued tube, such that when the next pipe is introduced, the joint contracts and the tightness of the joint area is secured; and in which registers with more sophisticated designs and designs have been developed, among which, for example, the seal of the EP02l1428 register in which an elastic joint with two widening of variable shapes at its ends that double can be defined containment against possible leaks; the joint defined in register ES233242 which defines a joint for pipes with a plurality of teeth or projections, which, as in the previous case, allow a good sealing of the joint area between two pipes; the register US20 130000 1821 in which a joint with perimeter gaps in one of its faces is defined in such a way that a vacuum or suction effect is generated against the face of the other pipe and the tightness is ensured; the US7328493 register defining a joint with different areas, such as for example one with a plurality of teeth and with differentiated ends, intended for joining pipes of a metallic nature, with which said joint zone is also secured; or the register US7845686 that defines a combined system of pipes with special grooves that require a joint with specific grooves for said connections, in which the joints are plastic and can have an area with particular teeth or widenings in different areas. In all existing antecedents, as can be seen, joints of a plastic and / or elastic nature are defined, which have a nexibility that allows them to be manually introduced, as well as to the adequacy of their position or shape so that the introduction from the next tube possible and ensure the tightness of the joint area.
    However, none of the previously defined joints have a high resistivity, and both in the case of being able to suffer unexpected solicitations, that the union is not perfect and the introduction of the next pipe can damage said joint, that the alignment between pipes is not correct, that the manual coupling in the grooving of the glued tube is not good due to a defect in the plastic material or in the grooving itself, or due to a bad coupling between the tubes can cause the joint to move, break , or it is deformed so that the joint is susceptible to not being airtight, and therefore it is common to see in the pipe assembly that when pressure tests are carried out, there are leaks in various joints due to these problems derived from low resistance .
    5 For this reason the need arises to develop a joint for coated pipesdefined below, which enjoys similar flexibility of jointsplastic which allows its installation manually, and also enjoys a highresistance only to the reach of steel joints which makes it resistant toactions not supported by plastic material joints. Taking into account the
    10 existing background and the solution described below, it can be emphasized that the present invention solves the problems existing in the joining of glued pipes and introduces an optimized sealing joint solution for the connection of pipes, in addition to its Easy installation reduces both investment and manufacturing costs.
    DESCRIPTION OF THE INVENTION
    The joint defined herein is a reinforced joint for the connection and coupling of glued pipes with which a perfect sealing of the joint area between said pipes is achieved due to the combination of the 20 previously defined characteristics of flexibility and high strength. Taking into account this essential aspect, this joint is a single piece with a flexible ring shape of a plastic or synthetic nature, such as rubber or rubber, which is internally reinforced by a rigid ring which gives it strength and rigidity during operation. This rigid ring is preferably of nature
    25 metal, like steel, and can also be made of high rigidity plastic. By combining both materials in a single piece, the joint is flexible enough to be manually placed in the groove of the coated tube, as well as being rigid enough to provide the joint with the qualities of rigid steel joints.
    In the definition of the joint, it is not only important to define the structure, which as it has just been exposed is a single piece composed of two different elements, a flexible body that incorporates a reinforcement in its core, but it is also important to define the External fonna necessary to ensure the correct tightness of the joint between the tubes.
    The reinforced joint is a single piece with a ring configuration that is installed in the groove contour of the end of the glued tube. This joint has a particular and necessary section, defined essentially in a flexible body with rounded contours and a high strength internal reinforcement.
    The body with rounded contours has a configuration that fits the groove of the glued tube. This implies that in its upper part there are two convergent faces with a rounded joint, therefore said flexible body of synthetic nature being in total contact with the groove located in the inner face of the glued tube. In its lower part, a horizontal and split base is defined in which, at an intermediate point, a triangular shaped tab protrudes. When the joint is in the resting position, the tab protrudes from the horizontal of the base. while when the board is working, that is. The union between both pipes is made, the flange is deformed towards its upper part so that the base of the flange is placed horizontally giving continuity to the horizontal base of the main body. In this way, when the joint is working, the base of the joint is horizontal in its entirety and is in full and direct contact with the outer face of the pipe that has just been introduced. This deformation is possible because as mentioned, the base is split, that is, it has a horizontal part but the other part of the base is open, so that there is an open area that hangs the area of the flange can be occupied when deformation occurs.
    At this point it is important to say that the deformation of the joint and the perfect fit or coupling with the walls of the tubes is because the material of the body is flexible and synthetic in nature. But to solve the problems derived from an excess of flexibility, in the present meeting there is the second basic element in its structure, which is the internal reinforcement, with which the problems indicated in the background section are solved.
    The internal reinforcement is an element that is located mainly in the part of the joint that is exposed to the blow or the introduction of the pipe, and that we have previously commented that it has a horizontal base. This reinforcement is in any section a flat element, like an iron, which extends obliquely inside the flexible body from the area of the joint where the pipe is introduced to the opening area of the body, or the area occupied by the deformation of the flange. In this way the reinforcement forces the gasket to remain in contact at its upper part with the groove of the glued tube and forces the horizontal base to remain in a horizontal position without the friction of the introduced tube twisting the lower part of the flexible body, it allows the flange to be able to deform properly in the open space enabled for that purpose in the body, and makes that once the tube has been introduced, the base of the body including the flange is in direct and total contact with the outer face of the tube inserted. By means of this reinforcement, the correct mechanical behavior of the joint is ensured against the efforts produced in the introduction of a tube into the other, as well as the joint can be reinforced against the tensions and pressures produced by the flow of the fluids that run through said pipes, taking into account that the junction zone between two pipes is a weak point in a hydraulic line.
    To better illustrate the previously described, it should be mentioned that the flexible body may vary in its composition depending on the type of fluid, temperature of this fluid or the exposure of the joint to the elements. The fluid used in conduits of coated tubes is generally potable water and sanitation, and therefore preferred compositions of the flexible joint body can be EDPM rubber, NBR rubber or silicone rubber. In all these cases, as defined above, the body is itself a flexible annular element of a plastic or synthetic nature, such as rubber or rubber. On the other hand, the main characteristic of the reinforcement is that of its high strength, for which it is considered that the preferred composition of said ring is steel, which to acquire the characteristics of slight elasticity must be tempered and tempered, of the type conventional used in elements such as springs, although the reinforcement can also be of other compounds with high resistance such as fiberglass or carbon fiber. Also in this case, the reinforcement must be an annular element that, although having a certain elasticity, is a strong and rigid element so that its correct function against the stresses that the joint assembly receives. The combination of the characteristics of the elements that make up the joint makes the reinforced joint meet all the necessary requirements for proper tightness in the union of glued pipes.
    In order to complete the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part thereof, with an illustrative and non-limiting character of lengths, sizes or contours.

    Description of the drawings
    Figure I represents the reinforced joint in perspective, and it can be seen how it is a single piece consisting of a body (1) with rounded contours that has a configuration that fits the groove of the glued tube, said body (1 being) ) a flexible element of a synthetic nature, and also constituted by an internal reinforcement (2) of high resistance. In addition, in the lower part of the body (1) there is a horizontal and split base from which a flange (3) with a triangular configuration and constituted by the same material as the body (1) stands out at an intermediate point. The body has an open area (not referenced) intended for the necessary deformation of the flange (3) when the union of the two pipes occurs. You can also see that the internal reinforcement
    (2) is an annular and flat element, like an iron, which is located mainly in the part of the joint that is exposed to the blow or the introduction of the pipe, the reinforcement (2) extending obliquely inside the body ( 1) flexible to the opening area of the body or the area occupied by the deformation of the flange. Taking into account the basic composition of the joint, it can be said that the assembly is a single piece that is arranged in the form of a ring, and that it is flexible due to the plastic nature of its body, and that it is reinforced by an internal reinforcement rigid which provides strength and rigidity during operation. By combining both materials in its structure, the joint is flexible as it can be placed manually in the groove of the glued tube, just as it is rigid so as to give the joint the qualities of the steel joints.
    Figure 2 represents the serial connection of two glued pipes (4 and 4 '), so that it can be seen that each pipe in a cup has at one of its ends a slightly widened area where a groove (5 and 5 ') in which the reinforced joint object of the present invention is located. The connection is simply by introducing the smooth end of a glued pipe (4 ') into the slightly widened part and which has the groove (5) of the previous glued tube (4) in which the joint object of the present has previously been manually introduced Invencion
    In Figure 3 it can be seen clearly how the reinforced joint, shaped by its flexible body (1) with an flange (3) and an internal reinforcement (2), is a single ring-shaped piece that is manually inserted inside of the glued tube
    (4) and is located in the groove (5), in such a way that in rest position the upper part of the reinforced joint adheres to the internal walls of said groove (5) pending the introduction of the next cased tube .
    Figure 4 is a representation that continues with the previous explanations and illustrates the section of the connection area between two glued pipes (4 and 4 ~), and represents the moment prior to the connection between said pipes and therefore represents the joint reinforced in rest position waiting for the connection between the tubes. In this figure it can be seen how the body (1) has the rounded contours and has a configuration that fits the groove (5) of the glued tube (4). This implies that in its upper part there are two converging faces (1 1 and 12) with a rounded joint, therefore said body (1) being flexible in total contact with the groove (5) located on the inner face of the glued tube . In its lower part a horizontal base (14) is defined and a part from which a flange (3) with a triangular configuration protrudes at a point. In this resting position it is noted that the base of the body (1) is open in such a way that there is an open area (1 3) destined to be occupied by the flange (3) when deformation occurs by the introduction of the glued tube. This figure also shows how the internal reinforcement (2) is located mainly in the part of the joint that is exposed to the blow or the introduction of the pipe (4 '), extending the reinforcement (2) obliquely inside the body (1) flexible to the opening area of the body or the area occupied by the deformation of the flange (3).
    Figure 5, as a continuation of the previous figure, represents the moment of connection between both pipes (4 and 4 '). This figure highlights how the flange (3) has been deformed and has occupied the open area (13) of the flexible body (1). At this time the board is working and ensuring the tightness, that is, the tab
    (3) deforms towards its upper part so that part of the flange is placed horizontally giving continuity to the horizontal base (14) of the main body. In this way, the joint is on its upper part joined to the internal face of the groove (5) of the glued tube (4) by its converging faces (1 1 and 12), and attached to the external face of the next coated rubble ( 4 ') by the horizontal extension of both the horizontal base (14) and the flange (3). At this point it can be seen how the internal reinforcement (2) ensures the correct mechanical behavior of the joint against the efforts produced in the introduction of a tube in the other, as well as allows the joint to be reinforced against stresses and pressures own produced by the currents of the fluids that run through said tubenas, taking into account that the area of union between two pipes is a weak point in a pipe.
    Figure 6 shows the necessary correlation between the dimensions of the groove (5) of the glued tube (4) and the reinforced joint. In particular, the angles of the convergent faces (1.1 and 12) can be observed with respect to the horizontal base (14) and its correlation with the angles of the internal faces of the groove (5) with respect to the horizontal surface of the tube (4) . It can be seen that there is an angle and that it is the angle of the converging face of the body (1) that makes a frontal stop with the face of the groove (5) of the glued tube (4) when the second tube e is inserted into the joint , this angle being and preferably in a range between 30 ° and 60 °. On the other hand
    there is an angle that is the angle of the converging face of the front body (1) that engages on the face of the groove (5) of the glued tube (4) in the part where the next tube is inserted, this being angle p preferably in a range between 300 and 60 °. Although both angles match the range, it stands out that they do not have to be equal. Finally, it can be seen how the internal reinforcement (2) extends obliquely inside the flexible body (1) to the opening area of the body or the area occupied by the deformation of the flange (3) generating an angle n that can be Consider how the bisector of the angle generated between the converging face of the front body (1) of which it remains is coupled on the face of the groove (5) of the cased tube (4) in the part where the next tube is inserted and the horizontal base, therefore it can be said that approximately n = pl2.
    Finally. Figure 7 shows a representation of the installation of a joint, which, as we have seen throughout the memory, is a manual installation, in which the joint is exerted a manual force (F) on a point of its contour and a defonation (6) is generated at that point of the joint in such a way that the joint as a whole acquires a bulging shape like a kidney_ Next, the joint is inserted into the groove of the coated tube. Once said manual force (F) is stopped and the gasket is in the groove. The joint returns to its conventional circular shape and adheres and completely attaches to the groove walls, ensuring the tightness at said point of connection between pipes.
    A preferred embodiment of the invention, taking into account the previous figures, can be defined as an annular gasket consisting of a flexible rubber body (1) with a flange (3) in its lower part and an internal steel reinforcement (2), having an open area (13) intended for deformation of the flange (3) by the insertion action of the next coated tube, in which the joint is inserted into a groove (5) of a coated tube (4), in such a way that the board has an angle
    and of 60 °, an angle pde 450 and an angle Q of 22 °, whereby a correct connection is obtained between the converging faces of the body (1) with the internal walls of the groove (5) and a strong connection against possible torsional stresses or pressure of the fluid due to the fact that once the next glued tube is introduced into the previous pipe, the body (1) and the flange defonation (3) generate horizontal surfaces, and therefore the entire contour of the body (1) is in contact with the two pipes, the reinforcement (2) ensures, reinforces and stiffens the assembly, and therefore a total tightness is achieved.
    Described sufficiently in what precedes the nature of the invention, taking into account that the terms that have been drafted in this specification should be taken in a broad and non-limiting sense, as well as the description of how to put it into practice, and, demonstrating which constitutes a positive technical advance, which is why registration is requested, being what constitutes the essence of the aforementioned invention, which is then specified in the following claims.
