Definitions

  • the present invention relates to a cage for containing stone materials for use in making dry stone wall structures, such as enclosure or retaining walls for steep and loose ground.
  • cages for containing loose stone materials for use in building dry stone wall structures as mentioned above are formed using flexible wire meshes, which are folded into box-like configurations, i.e. having cubic or cylindrical shapes, leaving an open portion, which is designed to allow the stone material to be introduced therein and to be later closed by tying the mesh wires.
  • the cages constructed according to the above discussed prior art suffer from the drawback of being somewhat deformable when they are empty, which makes it difficult to fill them with stone materials, and are still deformed when filled, especially under the compression stresses acting upon them when they are stacked to form a dry stone wall structure.
  • Such cages also have the drawback of not being easily handled by common lifting machines, as they have no strong coupling features for connection of the arms of the lifting machines.
  • Cages are also known, whose walls are formed with grids of crossed wire elements, which are connected, at their intersections, for example by welding, to form rectangular meshes, see e.g. JP 2015 094169 A .
  • the object of the present invention is to provide a cage for containing stone materials for use in building dry stone wall items, such as enclosure or retaining walls for loose ground, that can obviate the drawbacks of prior art cages and particularly can achieve proper alignment and connection of both longitudinally adjoined cages and superimposed cages, thereby strengthening the dry stone wall.
  • the cage of the invention which is generally designated by numeral 1
  • the cage of the invention has the configuration of a parallelepiped with rectangular walls, two of which, referenced 2 and 3, form longer sides, mainly extending in a longitudinal direction, as compared with the end walls 4 and 5 whose width sets the width of the cage structure and the thickness of stone wall structure to be formed.
  • the other walls, referenced 6 and 7 form the base of the cage and the cover, the latter being opened, as shown in Figure 1 , to pour the stone materials, generally referenced 8, into the cage.
  • All the walls of the parallelepiped configuration are flat and are formed using wire elements 9 perpendicularly crossed with wire elements 10 to form rectangular meshes 11. At their intersections the wire elements 9 and 10 are connected by conventional means, such as by welding.
  • the walls 2 and 3 that mainly extend in a longitudinal direction may have a curved profile, with their concave side facing the interior of the cage.
  • the aforementioned wire elements 9 and 10 may be advantageously made from galvanized aluminum, with a diameter ranging from 4 to 10 mm, preferably of 6 mm.
  • the meshes formed by the wire elements preferably have a size of 19 x 200 mm, and are arranged over a surface of 1000 x 1998 mm for each of the walls 2 and 3 that form the pair mainly extending in a longitudinal direction.
  • the cage comprises a plurality of bracing tie rods 12 between the walls mainly extending in a longitudinal direction, which are connected to the wire elements 10 by bending the ends of each tie rod into hooks.
  • the opposed walls 4 and 5 located at the ends of the walls 2 and 3 mainly extending in a longitudinal direction, are equipped with respective tubular rod elements 14 and 15, which are rigidly fixed to their respective walls, e.g. by welding on the wire elements 9 and 10 of the walls, such that they are located within the cage, with a vertical orientation relative to the base wall 6.
  • the tubular element 14 has openings 16 and 17 at its ends and the tubular element 15 has similar end openings 18 and 19, which can be all accessed from the outside of the cage, from the bottom 6 and the cover 7 respectively, through special spaces that are left open by the wire elements 9 and 10 of their respective walls.
  • the tubular elements 14 and 15 have an inner axial cavity with a four-sided, particularly square, cross section, although different geometric configurations may be also envisaged, e.g. polygonal or circular configurations.
  • the cage of the invention also comprises at least one pair of rod-like elements 20 and 21 in the form of posts, whose cross section conforms with that of the axial cavity of the tubular elements 14 and 15 with a smaller size, such that they can be telescopically introduced into the axial cavities as more clearly shown hereinafter.
  • the cage of the invention further comprises a plurality of coupling members 22, which are used to lift it by mechanical means, each comprising a plate-like portion 23 with slots 24, and a comb-like arrangement 25 with hook-like teeth 26, extending along the edge 23a of the plate-like portion 23.
  • the coupling members 22 are fixed to the edges of the cage 1 by fitting the hooks 26 of the comb 25 into corresponding meshes 11, proximate to the edges of the top side of the walls 2 and 3, in adequate positions for the slots 24 to engage and cooperate with the coupling devices of the lifting machines.
  • a cage 1 of the invention may be placed in a position in which a stone wall structure is designed to be formed, e.g. as shown in Figure 8 , to act as a base cage, and the portions 27 and 28 of the rod-like posts 20 are fitted into the respective tubular elements 14 and 15 toward the tip-like ends thereof, referenced 29 and 30 respectively.
  • the remaining axial portions 31 and 32 of the posts 20 and 21, terminating with the tipless ends 33 and 34, are separated by respective peripheral ribs 35 and 36, allowing abutment against the edge of openings 17 and 19 of the tubular elements 14, 15 when the posts are inserted therein.
  • the aforementioned ribs 35, 36 are placed on the posts 20, 21 for the portions 27 and 28 to be long at least 60% the overall length of their respective posts.
  • This length in a preferred embodiment, is equal to 1000 nm.
  • the portions 31 and 32 of the pair of posts 20 and 21 for the base cage 1, are intended to be fitted into the laying ground of said cage 1 which is designed to accomplish the base task of the stone wall structure to be built.
  • the base cage 1 may be fixed to the support surface also by means of plates, not shown, which are welded to the tubular element 14 and to the tubular element 15 that are fixed to the (reinforced concrete) understructure, by means of threaded bars and resin or by means of mechanical plugs, that are not shown because they have a conventional construction
  • Further base cages 1 may be laid in longitudinally adjoined positions, depending on the length of the stone wall structures to be formed, i.e. laid with the wall (5) at the end of said side walls (2, 3) mainly extending in a longitudinal direction of one cage adjacent to the wall (4) at the end of said side walls (2, 3) mainly extending in a longitudinal direction of the other cage.
  • proper horizontal alignment is obtained by connecting together two adjacent cages using a connecting fork device, as shown in Figure 9 and generally designated by numeral 37, i.e. by introducing the teeth 38 and 39, joined together by the plate 40 of the connection device 37, into the top opening 18 of the tubular element 15 of a first cage and into the top opening 16 of the tubular element 14 of the other adjoining cage respectively.
  • the cage 1a which is identical to the cage 1, is lifted by means of the coupling members 22 and is placed on top of the cage 1, with the portions 27 and 28 of the posts 20 and 21 fitted into the bottom openings 17, 19 of the tubular elements 14 and 15 of the cage 1a.
  • the structure has walls with even surfaces and well defined corners, and has an aesthetically pleasant appearance.
