[0002] A REINFORCED WIRE NETTING

[0003] FIELD OF INVENTION

[0004] The present invention relates to a field of reinforced wire netting. More particularly, a reinforced wire netting comprising an array of wires arranged in a side-by-side relationship to form polygonal meshes and each intertwined with at least one adjacent longitudinal wire.

[0005] BACKGROUND OF THE INVENTION

[0006] Metal nettings or reinforcement nettings are typically used for innumerable civil protection and containment works. They may be used for, by way of example, containing escarpments, for producing mechanically stabilized earth, producing or reinforcing embankments or the likes. Such nettings may be anchored to the ground by means of metal stakes or other anchoring which constitute to nodal points of its structure. Typically, the strength of known nettings is not sufficient to withstand the stresses to which they are subjected and it is therefore necessary to superimpose reinforcing cables on the nets through the anchoring. In this case, previous iterations of such containment products tended to experience bulging on their outermost face when in an erected condition. This phenomenon causes early failure of the products as the infill material exerts pressure on a single wire.

[0007] Many technologies have been implemented to improve on reinforced wire nettings. A United States patent with publication no. US20210023605A1 discloses a metal net having entwined metal wires defining the meshes of the metal net comprising at least one elongate sensor element fixed integrally to the metal net, and is inserted into the net during the production thereof. The elongate sensor element may further comprise a wire of a material having a low coefficient of variation for the resistivity and a high gauge factor, preferably formed from constantan, or else may be of optical fibre or composite fibre type.

[0008] Another United States patent with publication no. US7325774B2 discloses a spiral double-twisted structure is provided having an n-th upper steel wire (An) and an n-th lower steel wire (Bn) which are paired with each other and rotated in one direction to form a front spiral twisted structure having a plurality of twists. Further, a k-th transverse steel wire (Ck) may be transversely inserted between the n-th upper steel wire (An) and the n-th lower steel wire (Bn) of the front spiral twisted structure. Additionally, the n-th upper steel wire (An) and the n-th lower steel wire (Bn) may be rotated in a direction opposite to the one direction after passing over the k-th transverse steel wire (Ck) serving as a centerline, in order to form a rear spiral twisted structure having a plurality of twists.

[0009] A European patent with publication no. EP0429106A1 discloses a method for reinforcing a top layer of a ground, which top layer consists of bitumen, asphalt of a hydrocarbon containing material of like nature, by fixing at least one reinforcing mat to the bearing surface or foundation of the ground to be reinforced and by then applying a layer of sufficient thickness to the foundation, so that the reinforcing mat is completely embedded in the top layer, whereby before applying the top layer, longitudinal elements are fitted that extend longitudinally of the reinforcing mat for fixing the reinforcing mat to the foundation and whereby these longitudinal elements are fixed to the foundation by means of fixing means.

US9469955B2 discloses a reinforced gabion comprising two adjacent walls with common edge manufactured using a single sheet of double twisted metal mesh fabric formed from metal wires which have two different diameters respectively corresponding to the two walls. Preferably, the metal mesh fabric has a mesh with at least one twisted side formed from at least two metal wires woven together in which each twisted side is aligned in the direction of the common edge between the two walls.

[0029] DETAILED DESCRIPTION OF THE INVENTION

[0030] Hereinafter, the invention shall be described according to the preferred embodiments of the present invention and by referring to the accompanying description and drawings. However, it is to be understood that limiting the description to the preferred embodiments of the invention is merely to facilitate discussion of the present invention and it is envisioned that those skilled in the art may devise various modifications without departing from the scope of the appended claim.

[0031] The invention will now be described in greater detail, by way of example, with reference to the drawings.

[0032] FIG. 1 illustrate a preferred embodiment of a reinforced wire netting incorporating aspects of the present invention. In this preferred embodiment, the reinforced wire netting may comprise of a plurality of wires, in particular metal wires la, lb, preferably made of steel or any type of malleable metal, with substantially high tensile strength for preventing early failure from external stresses or impact. The plurality of metal wires la, lb may include a first metal wire la and a second metal wire lb, each being arranged in a side-by-side relationship to one another to form a plurality of polygonal meshes 4, in which the metal wires la, lb are intertwined to form a plurality of spiral twisted structures. In a preferred embodiment, the metal wires la, lb may be coated with a polymer-type coating, such as, by way of example but not limited to, polyvinyl chloride (PVC) coating, electroplated or anodized metal coating, powder coating, or the likes. Preferably, the polygonal meshes 4 may be hexagonal -shaped, but alternative shapes like diamond-shaped meshes may be considered depending on requirement. Further, the spiral twisted structure may each define one of many intertwining regions 5, 6 where said spiral twisted structure may follow a single twisting direction, either clockwise or anticlockwise, in each intertwining region 5, 6. In this context, the intertwining of the first metal wire and the second metal wire forms a first intertwining region 5 for the reinforced wire netting. Additionally, the metal wires la, lb that form the polygonal mesh 4 through the spiral twisted structures have a diameter ranging between 1mm and 3mm, but is preferably below 3mm. The dimensions given hereinabove are only given by way of example.

[0033] In a preferred embodiment, the reinforced wire netting further comprising at least one longitudinal wire 2, preferably made of steel or any type of malleable metal with a high tensile strength. Preferably, the longitudinal wire 2 is intertwined with the first metal wire la at opposing ends of the reinforced metal wire netting, forming a second intertwining region 6. In this embodiment, the second intertwining region 6 is created by a plurality of twists of the first metal wire la around the longitudinal wire 2, and is preferably double-twisted, with the longitudinal wire 2 acting as an anchoring means for the first metal wire la to be intertwined to the second metal wire lb as in the first intertwining region 5, forming the spiral twisted structure that make up the plurality of polygonal meshes 4 thereafter. In this embodiment, the longitudinal wires 2 may have a diameter greater than 3mm, which is greater than the diameter of the metal wires la, lb. Alternatively, additional twists may be applied between the first metal wire la and the longitudinal wire 2 to increase security of said first metal wire la and said longitudinal wire 2. Similarly, the dimensions given hereinabove are only given by way of example.

[0034] In a preferred embodiment, the reinforced wire netting further comprising a plurality of reinforcement wires 3, which are configured to be transversely inserted through a space within the spiral twisted structure, in which the reinforcement wires 3 may be arranged in a position that is perpendicular to the metal wires la, lb and the longitudinal wires 2. Preferably, the reinforcement wires 3 may be a type of galvanized metal wire, preferably steel, that is coated in, by way of example, a zinc coating through means of hot-dip galvanizing or electroplating, in which the zinc coating may act as a sacrificial anode that corrodes preferentially over the underlying steel. In this embodiment, the first intertwining region 5 may be created by a plurality of twists, similar to the second intertwining region 6, but by the first metal wire la and the second metal wire lb around each other instead. In this embodiment, the first metal wire la and the second metal wire lb may be triply-twisted around one another, such that at least one reinforcement wire 3 may be inserted therethrough upon a first twist being applied between the first metal wire la and the second metal wire lb, with a second and third twists being subsequently applied to secure the reinforcement wire 3 in place while maintaining an equidistant space between the reinforcement wire 3 and each formed polygonal mesh 4. Further, the reinforcement wires 3 may also be equidistantly spaced from each other at a distance of less than one polygonal mesh 4 apart, as illustrated in FIG. 1.

[0035] Alternatively, the first metal wire la and the second metal wire lb may incorporate additional twists that may accommodate the insertion of more than one reinforcement wires 3 therethrough, resulting in improved structural integrity and improved resistance to deformation due to external impact or stresses. In this embodiment, the reinforcement wire 3 may have a diameter greater than 3mm, which is greater than both the metal wires la, lb and the longitudinal wires 2. Here as well, the dimensions given are only given by way of example.

[0036] FIG. 2A to FIG. 2C illustrate exemplary embodiments of the reinforced wire netting being used as an outermost face 7 of containment structures 8 of varying shapes, sizes, and operations. The containment structures 8 may be, by way of example but are not limited to, gabions which are wire mesh baskets that are typically fdled with stones or other materials for use in retaining walls, riverbank stabilization, erosion control, and noise barriers; geocontainers that are typically filled with materials such as soil or concrete; rockfall nets, or the likes. Advantageously, the configuration of the reinforced wire netting as explained above, eliminates the use of welded mesh panels for reinforcement. Naturally, many variations may be provided for without thereby departing from the scope of the present invention. For example, the reinforced wire netting which form the containment structures 8 may be arranged in different orientations, with the longitudinal wires 2 being positioned horizontally while the reinforcement wires 3 being still positioned at a right angle relative to the longitudinal wires and the metal wires la, lb.

[0037] The present disclosure includes as contained in the appended claims, as well as that of the foregoing description. Although this invention has been described in its preferred form with a degree of particularly, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangements of parts may be resorted to without departing from the scope of the invention.
