Definitions

  • the present invention relates to a shelter structure, in particular for electrical equipment, for example for telecommunications systems, normally known with the English term "shelter”.
  • WO2007144913Al in the name of the same applicant describes a particularly advantageous shelter having a modular structure, that is to say consisting of a series of elements assemblable, even in the place of use, extremely fast to assemble and suitable for making shelters of different sizes, as needed.
  • the shelter structure described rests on the ground by means of support feet screwed to the frame of the structure.
  • the purpose of the present invention is to provide a shelter structure which effectively permits a reduction of installation times and costs, even when the ground conditions of the site do not allow it to be merely laid on the ground.
  • Figure 1 is an exploded perspective view of the support frame and reinforced concrete base of the shelter structure according to the invention
  • Figure 1a is an enlarged view of the detail in the box in figure 1 ;
  • Figure 2 is a section of a shelter according to the invention when assembled
  • Figure 2a is an enlarged view of the detail in the box in figure 2 ;
  • Figure 3 shows the reinforced concrete base in a ground view
  • Figure 3a is an enlarged view of the detail in the box in figure 3 ;
  • Figure 4 shows the base in a side view
  • Figure 5 is a cross-section of the base along the line E-E in figure 4 ;
  • Figure 5a shows an enlarged view of the detail in the box in figure 5 .
  • the shelter structure according to the present invention is globally denoted by reference numeral 1 and comprises a load-bearing frame 10, which supports the floor 20, the walls 30 and the roof 40 of said structure, a base in prefabricated reinforced concrete 50 suitable for being transported and laid on a support plane of the shelter, and attachment means suitable to connect said base in reinforced concrete 50 to said load-bearing frame 10.
  • the base in reinforced concrete 50 is in the form of a cement plate, reinforced with at least one metal mesh 52, preferably a double mesh, building before realisation of the excavations suitable for housing the shelter, as a separate and independent unit from said excavation, and suitable for being transported to the place of use and simply laid on a support plane, without the need to be anchored to said plane.
  • the reinforced concrete base 50 is a shape and size substantially equal to that of the floor plan of the shelter structure, for example a square floor plan.
  • the thickness of said base is 5 to 10cm, for example equal to 7cm.
  • the (double) metal mesh has a link having a diameter of 8mm.
  • the base in reinforced concrete 50 is screwed to the load-bearing frame 10.
  • the frame may therefore be anchored to the base directly in the place of use, rapidly and without the need for special equipment or skills.
  • the load-bearing frame has a base comprising angular connection joints 12 supporting horizontal bars 14 acting as sides of said base
  • the reinforced concrete base 50 is screwed to said angular joints 12.
  • angular anchorage plates 54 are drowned in the reinforced concrete base screwed to said angular connection joints 12. Said angular anchorage plates 54 are screwed to the angular joints 12 by means of a locking screw 56 which traverses a through hole 54' made in the angular plates 54 and screws into a threaded hole made in the angular joints, as shown for example in figure 1a .
  • the anchorage plates 54 are square and are positioned at the corners of the base, so as to be flush with the sides of said base.
  • said angular anchorage plates 54 are coplanar with the upper surface of the reinforced concrete base so as to abut with the lower surface of the angular connection joints 12.
  • the reinforced concrete base has an access channel 51 below each angular plate 54 so as to permit the insertion of the locking screws 56 from below.
  • said access channel 51 extends in height all along the thickness of the base. Consequently, once the base has been laid on the support plane and the load-bearing frame has been positioned over such base, the labourer can easily insert a hand under the anchorage plates and insert the locking screws in the respective threaded holes.
  • the anchorage plates 54 comprise, along the sides facing inwards, that is in contact with the reinforced concrete base, vertical walls 55 extending for example all along the thickness of the base and delimiting the access channel 51 for screwing of the locking screws.
  • reinforcement plates 60 are drowned in the reinforced concrete base 50 near the corners of said base.
  • Said reinforcement plates 60 are preferably made of steel, have a thickness generally ranging from 5 to 10 mm and are traversed by a plurality of through holes 61 so as to be tightly drowned in the concrete.
  • the reinforcement plates 60 are placed in contact with the metal mesh 52, for example, are welded to each other, so as to further stiffen the structure and, as will be explained below, provide an electrical connection for the earthing of the reinforced concrete base 50.
  • the outermost corner of the reinforcement plates is recessed so as to couple geometrically with the vertical walls 55 of the anchorage plates 54.
  • the vertical walls of the anchorage plates are welded to the reinforcement plates, so that the anchorage plates and reinforcement plates are positioned and drowned as a single body in the concrete of the base.
  • the reinforced concrete base 50 there is at least one through aperture 70 for the passage of cables 72 or other means between the inside of the structure and the ground which the base rests on.
  • the cables can be made to pass from the floor of the shelter without perforating the side walls 30, so that such walls are entirely utilisable throughout their width.
  • a braided copper wire 80 is drowned in the reinforced concrete 50 for the earthing of the structure.
  • said braided copper wire 80 is in electrical contact with the metal mesh 52 which in turn is electrically connected to the reinforcement plates 60 and then to the angular anchorage plates 54. Since the latter are, by means of the blocking screws 56, electrically connected to the support frame 10 which has its own earthing circuit thanks to the braided copper wire 80 the reinforced concrete base 50 has the same earthing potential as the load-bearing frame 10.
  • each one of these has three arms orthogonal to each other and extending in the three spatial directions x, y and z.
  • the load-bearing frame 10 of the shelter structure then comprises a series of hollow horizontal bars 14 suitable for being fitted at the ends to the horizontal arms of said angular joints 12 and a series of hollow vertical uprights 16 suitable to be fitted at the ends to the vertical arms of said joints.
  • the structure lastly comprises a plurality of rectangular panels suitable to form respectively the walls 30, the ceiling 40 and the floor 20 of the shelter.
  • Each of the horizontal bars 14 has longitudinally, that is in the direction of its horizontal extension and preferably all along its length, an outer vertical support shoulder 14' of the vertical panels acting as walls 30 of the structure.
  • Each of said horizontal bars 14 further defines a horizontal shelf 14" for supporting the horizontal panels acting as floor 20 or the horizontal panels acting as roof (depending on whether it is a bar of the perimeter of the base or of the ceiling of the structure).
  • the horizontal shelves 14" of the horizontal bars of two opposite sides of the base of the structure support intermediate horizontal bars 15 having a " ⁇ " section such as to permit the support of multiple panels acting as floor 20.
  • the height of the horizontal shelf 14" in relation to the base in reinforced concrete 50 and the height of the intermediate horizontal bars 15 define the height of the cavity 21 between the base 50 and the floor 20 of the shelter. Thanks to such cavity 21, the floor 20 is not directly in contact with the base in reinforced concrete 50 and, in the event of flooding, the cavity 21 acts as an out and out trap to prevent the floor from getting wet except when the level of water exceeds the height at which the bottom of the door of the shelter is placed, that is to say the height of the floor of the shelter in relation to the ground.
  • the horizontal bars 14 and the uprights 16 are further secured to the angular joints by means of cross screws which connect the end portions of said bars and uprights to the respective arms of the joints.
  • a foot for the support of the shelter structure on the ground may be screwed.
  • the same shelter structure may be supported, depending for example on the ground where it is to be located, either by the reinforced concrete base or by simple support feet.
  • the realisation and installation of the shelter structure according to the invention therefore foresees the realisation of the entire structure in the factory, in particular the load-bearing frame and the base in reinforced concrete.
  • the load-bearing frame and the base in reinforced concrete are then transported to the installation site of the structure; the base in reinforced concrete is positioned in the excavation, on a support plane made previously and without the need for anchorage.
  • the load-bearing frame can be attached to the base in reinforced concrete, for example by screwing.
  • the other elements of the shelter structure such as the panels forming the floor, the walls and the roof, can be connected to the load-bearing structure.
