Definitions

  • the present invention relates to a raised-access floor.
  • This raised access floor has optimal characteristics as regards fire resistance by virtue of its particular configuration, and protection against fractures, wear and abrasion, in particular during its handling and assembly, which also determines a greater durability which leads to lower costs.
  • the raised-access floor is a system which arises from the need to conceal the large number of installations present in working areas, technical rooms or other places where there is a great density of cables, piping and ducts of various types.
  • the raised-access floors for interiors enable the distribution of installations under the floor, whilst making them quickly and simply accessible, allowing a convenient access to the installations at the same time as an easy and fast replacement of parts.
  • the slabs or boards that form this type of floor are normally placed without the need for gluing on a height-adjustable steel structure or pedestal, achieving a firm false floor on the existing deck.
  • the inspectable raised-access floor is adaptable to any class of space and constructions and is generally composed of slabs of standard measurement on said pedestal creating a chamber (plenum) which defines a free space under the slabs which enables the placement of telephony, electricity, water, air conditioning installations, etc.
  • the slabs can be configured in different materials which do not always properly adjust and/or require coatings for their protection and adjustment, which on occasions require later grinding treatment, which are particularly expensive.
  • the raised-access floor has the problem that is deforms and melts, and it therefore hinders the passage of fire brigades.
  • EP1022400 which describes a composite refractory building material that is a material in which a reinforcing layer composed of a thermosetting resin and a mineral fiber is provided on at least one side of a porous inorganic core material such as a plasterboard. A plurality of plasterboards may be laminated. A covering layer for preventing a plaster powder from flying may be formed on a butt end surface of a refractory composite constructional material. A patterned layer or an electromagnetic wave shielding layer may be provided on a refractory composite constructional material.
  • a resin composition comprising a thermosetting resin and an elastic polymer has the nail endurance force. This resin composition may be impregnated into a porous substrate or a fibrous substrate and cured to make a molded sheet which may be laminated on a core material to make a molded plate.
  • the present invention is defined by a raised-access floor according to claim 1, having improved characteristics, among others, as regards fire resistance.
  • the raised access floor comprises a slab which incorporates a core of any material, whether porous or not, in which case it may have a porous primer, which may be, for example, a stony, ceramic, fibre, wood or other material, comprising in its edges a covering or layer of thermosetting resin, which may have a thickness in the order of between 1 and 1.5 mm for example, and which guarantees its hermetic sealing, and it comprises metal supports which emerge from the lower surface of the core and determine an elevation of the core and, therefore, a space between supports which allows, for example, the passage, of ducts, pipes or cables.
  • a porous primer which may be, for example, a stony, ceramic, fibre, wood or other material, comprising in its edges a covering or layer of thermosetting resin, which may have a thickness in the order of between 1 and 1.5 mm for example, and which guarantees its hermetic sealing
  • metal supports which emerge from the lower surface of the core and determine an elevation of the core and, therefore, a space between supports which allows, for example
  • the supports determine the permanent lift of the slab and, therefore, the floor.
  • the metal character of the supports guarantees this lift, since the supports are not going to be affected by the fire, whilst the fire consumes the melting materials in the environment, maintaining unalterable the stability of the floor, which would facilitate the passage, for example, of the fire brigades.
  • the metal supports also allow establishing an earth connection of the slab.
  • the metal supports may consist, for example, of bushings of hexagonal configuration or another, and its internal bore may or may not be threaded. Furthermore, the way in which the joint of the supports to the core is established may be, for example, by gluing or by moulding.
  • feet which allow a greater height elevation of the slab and which are fundamentally formed by a tubular metal piece which would remain underneath and in contact with the metal support in order to provide continuity in its earthing, as well as provide it with stability.
  • the tubular parts of the feet house bolts which protrude by at least one of their ends and which are designed to thread in the threaded bores of the metal supports.
  • the tubular parts may be coated with a resin and have hexagonal configuration, and they may protrude with respect to the resin, for example, by one of its ends, so that they allow its gripping by a tool that provides the turning and, therefore, the consequent displacement and positioning in height of the foot with respect to the support.
  • the raised access floor incorporates metal blocks which may be manufactured by plate stamping, wherein each block consists of several housings designed to receive the feet of adjacent slabs the corners of which join in a same point. In this way, with a block positioned in accordance with the corner of each slab, it guarantees the positioning and adjustment of the slabs that join in each block, and therefore, their assembly and dismantling.
  • This first layer of resin may be crystallized with silica load.
  • it may incorporate a second layer of resin, applied on the first layer, which would give the core elasticity and could be formed by an epoxy of elastic components.
  • the first and the second layer of resin may cover part of the supports, leaving one/some of said supports with the end of the metal surface of the bushing uncovered.
  • the raised access floor comprises a slab provided with a core (1) which is coated in its edges by a layer of thermosetting resin (2), and which shows, in figure 2 , metal supports (3) which emerge from the lower surface of the core (1), which determine an elevation of the core (1).
  • the lower surface of the core (1) of the slab represented in figure 2 is covered by a first layer of resin (4) which is in turn extended around the metal supports (3) so that they define protuberances (5) which cover at least partially at least part of said metal supports (3).
  • the metal supports (3) of figure 2 have an inner threaded bore (6) designed to receive a bolt (7) which forms part of a foot (8), represented in figures 3 and 4 .
  • the foot (8) comprises a tubular metal piece (9), as observed in figure 3 or 4 , provided with an inner thread (10) which houses said bolt (7) and a resin coating (11) which surrounds said tubular metal piece (9).
  • tubular metal piece (9) has a hexagonal configuration, which allows its gripping by a tool so that it regulates the height and positioning of the foot (8) with respect to the metal support (3) by the introduction or extraction of the bolt (7) to/from the inner threaded bore (10).
