Definitions

  • This descriptive report refers to a refinement in metal reinforcements, composed of claws that at their ends interwoven with a single cable threaded behind the tension claws that is subsequently covered by a layer of polyurethane or other class of synthetic material, presenting a set of sieve mesh by vibration, providing polyurethane with the figure of the mold prepared for this purpose in which the tension clamps and the cable both covered by the polyurethane mesh act as metallic elements, avoiding the elastic deformations characteristic of the synthetic material mesh and providing a robust consistency.
  • the general purpose of the present invention is to provide an armature support with tension claws and cable to integrate them in a mesh of polyurethane or other synthetic material that we solve or refine in a simple way and with economic assembly the problems previously raised.
  • This assembly is done by presenting on the tension claws, bent at an acute angle and located at both ends, crimping a single cable that links from one to the other through the holes presented as a comb on the shortest side of the angle , while the longer side has holes torn as an eight with its curved and larger ends, which connects on one side of the end with a slot that serves to thread the single cable when introduced through the hole torn as a eight and pass it through the inside of the tension claw, this cable will have a distance of passage according to the size of the grading mesh.
  • the distance between tension claws is obtained by means of provisional mounting shims that keep the determined distance between claws fixed and with this the positioning of the cable is started by fixing it on the initial claw with the shipments of the cable itself to the opposite claw, passing from a hole to another threading through The groove and changing the face of the claw through the torn hole, following the cable with return to the initial claw and so on until all the surface of the armature is completed in parallel, whose only final cable is clamped on the cables centered in the holes end of the corresponding tension claw.
  • the cable conduction throughout its route is carried out through the lower and outer part, except when passing through the torn holes in the form of eight that passes inside the claws that have a wide radius that eliminates any possibility of cutting and The same happens with the cable passage holes that have two round countersunk holes avoiding the live corners, both in the comb-like holes and the torn holes in the way of eight. It has been demonstrated in the laboratory resistance tests that in the torn holes in the form of a comb forming passages, the cable has less than five times the tensile force between the claws based on the physical laws of the cables wound to a drum, drumming the external curvature of the stress load.
  • the position of the cables allows to center them left or right with precision on the mold before casting the polyurethane or synthetic resin, also allows to increase with ease and low cost the number of cable passages between claws to achieve the total force of sufficient tension without risk of breakage. It is an added advantage that the polyurethane or resin fully encapsulates the metal armor which, as said, consists only of the two tension claws with their corresponding holes and a single cable.
  • Fig. 1 is a set of the screen mesh (1) showing the interlocking of the cable (3), in correspondence with the tension claws (2), with a schematically cut detail of the sieve (4).
  • Fig. 2 corresponds to the longitudinal section of the mesh assembly (1), one end is sectioned by the cable through zone (3) while at the other end the section crosses the mesh (4) where the calibrated sieve holes (4.1).
  • Fig. 3 comprises a perspective detail of the mesh itself (4) where the holes (4.1) that classify the size (P) to be screened of aggregates or other products are observed.
  • Fig. 4 is a perspective view with the detail of one end of the tension claw (2), in which the single cable (3) is connected over the holes presented as a comb (2.1), to continue threading through the passage of a groove (2.4) of a width slightly greater than the diameter of the cable to the torn hole (2.5) and alternatively with the holes of the opposing tension claw with the same procedure and with the distance or passage (P) according to the mesh, observing the generous radius (2.3) and the chamfers (2.2) of the different holes where the cable (3) is pressed.
  • Fig. 5 contemplates an enlarged section detail of the holes (2.1 and 2.5) in which its cable positioning contour is rounded (2.2), to prevent the cutting effect on the tensioning of the cable (3), likewise the passage of the cable (3) is observed, through the torn hole in the form of eight (2.5) passing from the outer face of the pressure claw to its inner face.
  • Fig. 6 contains a figure in plan with the development of the sheet of the pressure claw (2) of the metal armor before being bent, the comb-shaped holes (2.1) are observed while in the opposite end the holes torn in the form of eight (2.5) all of them with the chamfers (2.2), the figure completes the grooves (2.4) of a width greater than the diameter of the cable, which allow the threading of the single cable (3) of The mesh
  • the simple embodiment of the screen mesh assembly (1) comprising the independent manufacture of the claws or tension jaws (2), composed of a sheet bent at an acute and wide angle can be observed bending radius with uneven sides and presenting parallel and equidistant open holes (2.1) on the shorter side, with rounded countersunk holes (2.2) both inside and outside, while on the longer side of the acute angle it has holes torn in the form of eight (2.5), also with the perimeters of contact with the rounded countersunk cable (2.2), as well as a grooves (2.4), of width slightly greater than the diameter of the cable (3), which allows threading and the passage of the outer face to the inner one, avoiding forcing the tension claw when tensioning the mesh in the working position with the sieve; on the other hand, the situation of the holes (2.1 and 2.5) with a passage (P) are those that determine the position of the holes (4.1) classifiers of the size of the aggregates or other materials to be screened that are deposited on the sieve mesh (4).
  • a tension claw (2) is arranged on a mounting table on each side according to the desired length of the screen mesh and by means of provisional mounting shims allow maintain the desired distance and start the assembly or threading of the single cable, whose initial end is fixed (3.1) by the cable itself in its round trips on the open holes (2.1) with passage (P) through the torn holes ( 2.5) by changing the cable of its external contour to the inside of the claws or tension jaws (2), and with this we avoid that the direct effort of the tensioning force is supported by the wing that provides the tension clamp itself, passing through both the cable (3) from one end to the other through the open holes (2.1), forming a comb crossing the torn holes (2.5), all these holes have two rounded chamfers (2.2), this cable (3) goes from a hole to another in parallel with a passage (P) determined by the sieve of the screen mesh (4) until the entire surface of the reinforcement is completed, whose end end is fixed (3.1) by the cables centered on the end holes of Ia ga corresponding voltage (2).
  • the materials preferably in the case of the claws or jaws (2) will be made of laminated and bent laminated steel sheet with a generous radius while the cable (3) will be of commercial interwoven steel wires, the sieve of the mesh (4) it will be cast with synthetic material preferably of polyurethane.

Abstract

L'invention concerne une amélioration apportée à des armatures métalliques, caractérisée par l'utilisation de pinces, lesquelles sont entrelacées les unes avec les autres au niveau de leurs extrémités avec un câble unique enroulé derrière les pinces de tension qui est par la suite recouvert par une couche de polyuréthanne ou d'un autre type de matière synthétique, pour former un ensemble maille de tamisage pour une classification par vibrations. Le polyuréthanne et la forme du moule spécialement préparé dans laquelle les pinces de tension et le câble recouverts par le tamis en polyuréthanne font office d'éléments métalliques, ce qui permet d'éviter les déformations élastiques propres au tamis en matière synthétique et d'obtenir une consistance robuste.
