Definitions

  • the present invention which is intended to be protected as utility model, relates to a fence used for closing, made of non-metallic material.
  • this fence is specifically designed for closing and protection of railway lines, it can also be used for any other type of precinct required to be fenced and protected, such as a school, a farm, a port, etc.
  • fences used for closing are made mainly of iron.
  • the metal fences although they have great strength and resistance, have significant drawbacks, since they are susceptible to corrosion, especially if they are located near the sea, and further require the maintenance of exterior paint and are even stolen to be sold as scrap, etc.
  • the present invention describes enclosure fences with a non-metallic composition, which avoids the aforementioned problems while retaining their mechanical properties over their metal counterparts.
  • the present invention relates to a fence for urban or rural closings formed by a structure comprising some square section tubes or uprights among which are arranged a series of vertical bars crossed by at least one horizontal bar linking together said vertical bars and also with the uprights.
  • Each upright lies on an anchoring part through which the fence is fixed to the ground, wall or surface on which it is located.
  • the fence can be as long as desired, inserting uprights every certain number of vertical bars, so that although the fence has a great length is fully threaded through the anchoring parts that support the uprights.
  • the fence of the present invention having the structure described above is mainly composed of unsaturated polyester resin and non-alkaline glass fiber strands.
  • the percentage of resin of unsaturated polyester resin ranges from 30-55%, but preferably is 50%.
  • the percentage of non-alkaline glass fiber on the fence ranges preferably between 40-45%.
  • the fence of the present invention has a green color, although it is possible a wide range of colors according to the desired pigmentation.
  • the fence is made up of some square section uprights (1) that lie on the anchoring elements (4). These anchoring elements are screwed to the ground, wall or surface where the fence is placed. Between the uprights (1) a series of vertical bars (2) with I-shape section are arranged, which are crossed by two horizontal bars (3), one upper and one lower and which, in turn, pass through the uprights (1). In this preferred embodiment there are ten vertical bars (2) between two uprights (1).
  • the fence can be made longer by including a higher number of uprights (1) among which the vertical bars (2) are arranged.
  • the fence is composed of 50% of unsaturated polyester resin and 40-45% of non-alkaline glass fiber strands. The rest is formed by other components.
  • the fence with this composition in addition to presenting great advantages, as mentioned above, has excellent mechanical properties: tensile strength, resistance, compression strength... comparable to those of iron.
  • Example 1 a "tensile strength and density test" on the fence of the present invention is shown.
  • the samples consist of two fence elements of about 60 cm in length and 1 m in height. From these samples the test specimens described below were extracted:
  • One of the anchor brackets of the fence was carved to obtain a piece of tube with a square section of medial side of 674 mm and 115 mm of length with which its density and compressive strength was determined.
  • the tensile strength was determined in a multi-test press with a capacity of 100 kN, similarly to how is described in the UNE-EN 527-5 ISO Standard on determining the tensile properties of unidirectional composite plastics reinforced with fiber. In this test only the value of the maximum stress withstood by the specimens (in MPa) has been collected.
  • the compressive strength test of the supports has been carried out in a compression press with a capacity of 3000 kN, applying the load on two opposite planes of the walls of the carved tube, i.e. as if it were a crushing test, similarly to the method described in the UNE-EN 802 Standard for piping systems in plastic materials but determining, in this case, the maximum load (in kN) that the tube withstands in this arrangement before rupture.
  • the density has been determined by means of the hydrostatic balance following the widely standardized procedure for many materials such as, for example, that described in the UNE 53526 standard for elastomers.
  • Table 1 Test Specimens Maximum tensile strength (MPa) Individual values Mean value TRACTION T1 515.6 487.7 T2 459.8 Table 2 Test Specimens Density (kg/m 3 ) Individual values Mean value DENSITY D11 '1,840 D12 1,840 D21 1,840 1,820 D22 1,770
