    Method for unwinding a meshed structure on a surface and a system of
    unwind of a meshed structure
    OBJECT OF THE INVENTION
    The purpose of the present application is to register a method for unwinding a meshed structure on a surface, as well as a meshed structure, for example, metal for the formation of a slab.
    More specifically, the invention proposes the development of a method for unwinding a meshed structure on a surface, being formed by a plurality of transverse rods fixed longitudinally to each other, which is previously wound in the form of a coil before being extended on a surface.
    BACKGROUND OF THE INVENTION
    In the construction of buildings as well as other constructions it is well known to use slabs formed by meshed structures that can have considerable dimensions depending on the construction in which it is applied.
    Such meshed structures are transported from the point of manufacture to the point to be placed in a wound form in order to reduce the size of storage and transport in special vehicles. Thus, to carry out its placement on a surface it is necessary to use a large number of operators to unwind the meshed structure that must adopt a position with a bent back that can result in injuries or muscle aches in the operators, especially when it comes to meshed structures that have varying dimensions in width and length.
    In addition, the applicant is not currently aware of an invention that has all the features described herein.

    The present invention has been developed in order to provide a method that is configured as a novelty within the field of application and resolves the aforementioned drawbacks, also providing other additional advantages that will be apparent from the accompanying description. continuation.
    It is therefore an object of the present invention to provide a method for unwinding a meshed structure on a surface, being formed by a plurality of transverse rods fixed longitudinally to each other, for example by means of longitudinal wire rods, metal strips, etc. , which is previously wound in coil form before being extended on a surface, characterized by the fact that it comprises the following steps:
    - fixing one end of at least one sling at the end of the meshed structure that is located inside the coil in a rolled condition, such that the body of the sling runs longitudinally along the entire length of the meshed structure , Y
    - coupling the opposite end of the sling to a liftable external means, such that as the end of the sling is elevated the meshed structure is unwound along the surface on which it rests.
    Thanks to these characteristics, it is possible to facilitate the deployment and assembly of a meshed structure on a surface, such as those used in the formation of slabs used in the construction of a building that avoids or reduces the need to use a large number of Operators for the deployment or unwinding operations of the meshed structure. The fact of reducing the number of operators increases the safety in a work since it prevents a number of operators from being in contact with metal parts (wires that are part of the meshed structure) and can suffer cuts or wounds.
    It is another object of the invention to provide a system for unwinding a metal mesh structure for floors, for example, a structure formed from a plurality of longitudinally fixed cross rods, and is characterized by the fact that it includes at least one sling that It has one of its ends attached to one end of the metal mesh structure, the length of the sling being equal to or greater than the length

    of the meshed metal structure in an extended or deployed condition, such that the opposite end of the sling includes fastening means provided to engage an external lifting means.
    According to an embodiment of the invention, the aforementioned fastening means may be comprised of an eyelet that facilitates the attachment to a hook, for example, of a lifting crane.
    According to an embodiment of the invention, the sling has a width between 5mm and 300mm.
    Similarly, the sling can have a thickness in a range between 0.5mm and 7mm.
    Other features and advantages of the method and structure object of the present invention will be apparent from the description of a preferred but not exclusive embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which:
    BRIEF DESCRIPTION OF THE DRAWINGS
    Figure 1.- It is a perspective view of a sling that is part of a system according to the present invention;
    Figure 2.- It is a schematic elevation view of a rolled coil-shaped mesh structure according to the invention; Y
    Figure 3.- It is a schematic view of a sequence of the method according to the invention in which the directions of advance of the meshed structure and the lifting means acting on a sling linked to the meshed structure are indicated by arrows.
    DESCRIPTION OF A PREFERRED EMBODIMENT
    In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.

    In Figure 2 a sling can be seen that forms part of a metal structure for slabs, generally indicated by reference (2), said structure (2) being formed from a plurality of transverse rods (21) spaced apart from each other. . With particular reference to the sling (1) it comprises a flexible elongated main body (10) in which one of the ends of the sling is attached to one end of the metal structure by means of an eyelet termination (11) (see Figure 1), the sling having a length that is equal to or greater than the length of the metal structure in an extended or deployed condition. The opposite end of the sling (1) also includes fastening means, in this case an eyelet (12) which allows the sling to be coupled to an external lifting means, such as a conventional crane used in building construction. Mention that the terminations with eyelets (11, 12) can be made without folding the tape or folding the tape on itself, and instead of an eyelet a shackle, hook, carabiner, etc. could also be used.
    To facilitate the understanding of the elements shown in Figure 2, the sling (1) has been represented in broken lines.
    The sling (1) is made of synthetic materials, such as polyester, polypropylene, continuous filament polyamide with high tenacity that can have a width between approximately 5mm and 300mm while it can have a thickness between 0.5mm and 7mm ., and it is placed in the meshed structure during its manufacturing process, which optimizes the production process.
    In Figure 3, a sequence of the method of the invention can be seen more clearly, which is intended to unwind a meshed metal structure used for forging, which is previously wound in the form of a coil before being extended on a horizontal or substantially work surface. horizontal. In this way, firstly an end (11) of a sling is fixed at the end of the meshed structure that is located inside the coil in a rolled condition, such that the body of the sling runs longitudinally along of the entire length of the meshed structure.
    Subsequently, and as can be seen in Figure 3, the opposite end (12) of the sling is coupled to the (1) elevating external means, such that as the end (12) of the
    Sling (1) is raised the meshed structure (2) is unwound along the surface on which it rests.
    The details, shapes, dimensions and other accessory elements used in the method of the invention may be conveniently substituted by others that do not depart from the scope defined by the claims included below.
