    Bamboo gray screwed joint system
    DESCRIPTION
    TECHNICAL SECTOR
    The present invention relates to a system of bolted joints of metal parts for bamboo gray hair. This system turns out to be a system applicable to all types of bamboo structures whatever their geometry.
    BACKGROUND OF THE INVENTION
    At present, simpler joining methods are used but they do not provide high security. It is common to find the bamboo gray hair tied with braided rope straps between the gray hairs. The resistance of the same depends on the skill of the operator since there is no standardized method to perform this operation. In addition to the fact that the material has a greater friction wear and in many cases it is a natural material, so if it is not well treated, it can deteriorate more quickly.
    Another method that can be found usually consists of sectioning the gray hair to couple them together and join them by means of through screws. In some cases the ends are solidified by cement mortar. This method provides rigidity and safety but also weighs the structure, so it greatly limits its size and complexity.
    These past methods have deficiencies in terms of flexibility of use, handling and weight.
    explanation of the invention
    The proposed invention provides a system of bolted joints for bamboo gray hair comprising a set of metal parts mounted on a section of solid cane with polymer in which a metal rod and a prism are embedded

    metallic at its end which is fixed to the bamboo letter by means of a through screw that covers the entire channel transversely.
    Through the joint use of polymer, rod and metal prism attached to the bamboo cane we managed to increase the stiffness in the bamboo sections that support the joints without increasing the weight of the structure and reducing the consolidation time.
    The bolted joint system facilitates the assembly of the structure and allows the development of different designs using the pieces in combination. With the use of meteoric parts for bamboo card joints, we get these joints to have greater strength and durability.
    DESCRIPTION OF THE DRAWINGS
    To complement 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 of said description, where the following is illustrated and not limited to, :
    Figure 1.- Shows a front view of the bamboo letter (20) with a set of pieces of the invention.
    In section A we observe three of the elements that make up the invention. It shows the metal rod (17) that is embedded with polymer (23) in the bamboo letter (20) fixing it inside a metal prism bored in its base to embed the metal rod (17) and fixed to the bamboo letter (20) by means of a through screw (19) transversely to the bamboo letter (20) and to the prism. On the edge of the bamboo letter (20) where the metal rod is inserted we place a metal cone (5) that provides an aesthetic finish. Section B is composed at the top of the bamboo letter (20) by a longitudinal metal piece (9) with a curved surface at its base and perforated at the ends thereof, and a longitudinally located lug with an undulation at the top and three through holes to which the fork (11) is attached in the center although this piece allows up to three forks thanks to the three holes in the lug. At the bottom of the bamboo letter (20) we can see a curved longitudinal metal piece (8) with hollow cylinders at the ends of its base that are introduced into the

    bamboo cane (20) allowing the fixing of the metal part (9) to the bamboo cane (20), to which the necessary forks are added The metal part (9) and (8) are joined together by screws introducing them from the holes in the base of the metal part (9) to the hollow cylinders of the part (8).
    Figure 2.-We can see a transverse code of the bamboo cane (20) in which the details of the invention that remain within the bamboo cane (20) are appreciated. The metal rod (17) embedded with polymer (23) from one end of the bamboo cane (20), leaving a part of it outside it for attachment to other parts and at the other end coupled to the metal prism ( 1) that is inside the bamboo cane and acts as a stop for the metal rod (17). For the anchoring of the metal rod (17) and the metal prism (1) we use a through screw (19) that crosses the bamboo cane (20) transversely and crosses the metal prism (1) together with the rod forming a T. At the end of the bamboo cane where the metal rod (17) is inserted, we place a perforated metal cone at its apex to introduce the metal rod giving a more static finish to the section.
    Figure 3.-Union of metal parts (9 and 10). In the upper part of the bamboo cane (20) we observe the longitudinal metal piece (10) with a curved surface at the base of which it has two threaded hollow cylinders that are inserted into the bamboo caria (20) and corrugated lug with central perforation for coupling the fork (11). In the lower part of the bamboo cane we find the longitudinal metal piece (9) with curved surface perforated at the ends of its longitudinal axis and corrugated lug with three perforations to which fork (11) is attached. The metal parts (10 and 9) are joined together by means of a screw (22) inserted from the metal part (9) to the metal part (10) fixing both pieces (10 and 9) to the bamboo cane (20).
    Figure 4.- Shows a section of the union of two bamboo faces (20) by means of through screw (18) and solidified with polymer (23), being a realization that corresponds to the state of the known technique ".
    Figure 5.- Shows the union of several bamboo faces (20). By using a metal part (4) composed of three axes forming a star with three arms pierced at its ends with two lugs coupled parallel to each other with

    undulations in the upper part and three interns in each of the lugs we can join several bamboo cafes (20) from their ends. Bamboo cafes (20) at their ends are prepared according to FIG. 2. Joining three bamboo gray hair lengthwise and adjusting them on the same piano at its ends we place the metal piece (4) by introducing the metal rod into the holes of the base of the metal piece (4) fixing both elements by rosea. For a more aesthetic finish we put metal caps (21) at the ends of the bamboo cane (20), leaving these between the metal piece (4) and the bamboo cane (20). In the lugs of the metal piece (4) we place forks (11) and to these forks new bamboo cafes (20) are prepared prepared with the shape of FIG2 introducing the metal rod (17) of each of them in the forks (11 ) chosen.
    Figure 6. - It shows the union of several bamboo gray hair (20) through the use of a metal piece (3) in the form of two three-leaf clovers that cross perpendicularly along the central axis. In each of the leaves of both shafts a through hole is made resulting in the option of adding up to six forks to the same piece (11, 12, 13, 14, 15 and 16) depending on the need posed by the structure. In this figure we can see how two forks are added from the metal part (3); to the right fork with angle of 45 ° (15) and to the left double fork (13) that allows the union of two more forks. As we have explained about the metal part (3), the 45 ° fork (15) is joined together by joining both parts together by means of a bolt. The metal rod (17) of the bamboo card (20) is inserted into the fork (15). The end of the bamboo cane (20) that is attached to the fork (15) is embellished by a metal cover (21). Towards the left side of the metal part (3) we also have double fork (13) joining both pieces by bolt. To the double fork (13) we add a fork with Angle of 45 ° (15) in which the metal rod (17) of the bamboo cane (20) embellished at the end that joins the fork (15) is inserted by a metal cover.
    Figure 7.- It shows the union of bamboo gray hair (20) by means of the use of a metal piece (6) in the form of a cross with equal arms with two lugs with undulations in the upper part coupled parallel to each other to one of the axes of the piece. In each of the ends of the base of the metal piece (6) a groove is made to join the metal rod (17) of the bamboo cane (20). To each lug of the piece
    metal (6) through holes are used to couple forks (11, 12 and 15). In the figure we can see how in one of the lugs a 90 ° fork (12) has been attached to which the metal rod (17) of the bamboo bed is attached
    (twenty) . In the other lug of the metal part (3) three forks (11, 11 and
    5 15) to which three bamboo cahas (20) are attached by introducing the metal rods
    (17) in each of them. All bamboo boxes (20) are embellished at the end near the joining pieces (6, 11, 11, 12, 15) by metal covers
    (twenty-one) .
    10 Figure 8.- It shows the unibn of four bamboo cahas (20) through the use of metallic piece (7) composed of a longitudinal axis with two lugs coupled parallel to each other to the axis of the piece. At the ends of the base of the metal part (7) two through grooves are made to join the metal rods (17) of the bamboo boxes (20). The lugs have through holes to add the 15 forks and a wavy shape at the top for a greater range of rotation of the elements. In the figure we see two bamboo cahas (20) attached to the metal piece (6) by the metal rods (17). To the lugs of the metal part (7) two forks have been added. A fork with a 90 ° angle (12) to which the metal rod (17) of ia caha de bamboo (20) is attached, and another angle fork of 20 60 ° (16) to which the rod is added metal (17) of the bamboo bed (20).
    PREFERRED EMBODIMENT OF THE INVENTION
    25 For the assembly of the invention, we begin by preparing the sections of the bamboo boxes that will be part of the joints. The preparation consists of embedding a rod and metallic prism in the bamboo caha with the desired depth and fix both elements to the bamboo caha by means of a screw that crosses the bamboo caha across the width and crosses the prism attached to the metal rod and solidifying the entire 30 section with polymeric material.
    For the union of bamboo boxes, two or more elements will be used, using at least one base piece of unibn with lugs and a fork. These base pieces of unibn consist of one b plus axes, depending on the number of cahas to be joined. Both the lugs and the bases of the base pieces of unibn have 35 holes made that allow the union with the forks connecting to these
