Definitions

  • This invention refers to a procedure for installing a technical floor of the type mainly used in industrial or office premises, which includes the formation of a base structure, forming a structural filling and possibly a decorative covering, including opening systems for fitting different types of installations, such as electrical wiring or drainage conduits, as well as a structure for forming said base structure.
  • Technical floors can be defined as the type of flooring that allows access underneath these for fitting different types of installations. Though these can be removable, a permanent structure can also be set up.
  • Technological evolution meant that it was necessary for each machine or work station to have a set of conduits including, without implying any limitation thereby, electrical power and lighting connections, telephony, communications, water outlets or drains, pneumatic or hydraulic connections etc.
  • FIG. 1 shows an elevation of a basic unit of the technical floor of the invention, provided with a central opening for inspection;
  • FIG. 2 shows a plan view of the basic unit of the technical floor of FIG. 1 , on which a cladding for said floor can be fitted, such as a concrete casting;
  • FIG. 3 shows a plan view of a set of basic units set out in fitting position
  • FIG. 4 shows a cross-section of the technical floor of the invention in fitted position, provided with an inspection hatch and covered on the outside by cladding items such as tiles.
  • FIG. 5 shows a cross-section of a unit of the technical floor of the invention according to an embodiment in which the inspection hatch is formed by an exterior body and with an interior body like a basin supported on this, which forms a very strong opening for access to the interior space of the technical floor after pouring in concrete;
  • FIG. 6 shows a cross-section view of a unit of the technical floor according to the embodiment of FIG. 6 , but with the opening parts set out separately prior to being fitted and to pouring the concrete;
  • FIG. 7 shows a cross-section of the technical floor of the invention, according to what is represented in FIG. 1 , in which the central opening of the inspection hatch also includes a frame for supporting a cover;
  • FIG. 8 shows a frontal schematic view of an item for covering the lateral gaps in the technical floor units prior to concreting, providing with pre-cut zones for inserting tubes and other installations;
  • FIG. 9 shows a schematic cross-section view of an assembly of the technical floor of the invention provided with a support for connections, this support being raised over the height of the floor on which this is located;
  • FIG. 10 shows a schematic cross-section view of the support for connections of FIG. 9 ;
  • FIG. 11 gives a schematic plan view of the support for connections of FIGS. 9 and 10 .
  • a technical floor according to the invention consisting of a plurality of basic structural units 1 , normally made of a light plastic material, each of said units forming a surface determining a lower space 8 which determines a corresponding covering surface 2 at the top, as well as a lower edge 3 for supporting said unit 1 in the floor 13 .
  • Each unit 1 also includes an opening 10 , normally centred in this, said opening preferably being surrounded by a perimeter wall 9 .
  • the units 1 include cut-back portions for forming pillars.
  • the corners of each of the units are cut back by a portion 6 , so that the cut-back portions 6 of four adjacent units define a housing 12 for a filling material.
  • These portions can have a support base formed as a part of each unit 1 , or not have this, and have a wall for separation with the lower space 8 .
  • the upper surface has an upper edge 4 , able to be assembled with the corresponding adjacent unit 1 .
  • said edge 4 has a groove, so that the groove of one piece can be fitted together with the adjacent pieces.
  • each of the cut-back portions 6 also include an edge, identical to or different from the upper edge 4 , which is also able to fit into the adjacent unit 1 .
  • the coupling 16 of each item with the corresponding adjacent one is preferably by means of a male-female joint.
  • the properly assembled set of units 1 is deposited on the ground 13 .
  • a grid 11 of rods is fitted in order to constitute the reinforcement of the strong part of the technical floor according to the invention.
  • concrete 14 or some other similar material is poured onto the surface forming the set of units 1 . Since the cut-back parts 6 of the units adjacent to each vertex form a housing 12 , this housing will have the function of a strong pillar, whose strength will be distributed by means of the concrete at the top, leaving a continuous space at the bottom formed of the set of spaces 8 of the units 1 .
  • the openings 10 may include a protection cover (not shown) which prevents the concrete (or other material) from getting into the spaces 8 .
  • the concrete or strength-giving material poured into the set of spaces will have to reach and be left flush with the walls 9 of the opening 10 .
  • the height of said walls 9 or of the spaces 8 can be variable depending on the particular need of each application. That is, the height in an industrial area which has to support heavy machinery will have to be greater, both as regards the height of the space 8 for conduits and of the strength-giving layer than in a room intended for offices, for example.
  • the upper part of the technical floor can include an intermediate layer 15 for fitting a final floor 17 (that can be dismantled) or directly be said floor 17 .
  • the opening 10 is fitted with a frame item 18 , 20 , which comprises a reduction in its section on the inside (lower side).
  • the outer (upper) edge has a projection 19 with a greater section than the interior (lower) zone.
  • this defines a housing for a cover or lid 21 , which will be housed inside and could be withdrawn when this is considered appropriate.
  • a second type of frame piece 20 forms a housing for a basin, 22 , so that when the concrete is poured in, this basin will also be filled with concrete, giving the inspection hatch structural strength in accordance with the height of the layer of concrete and its reinforcement. The basin will be able to be taken out by simply pulling this, as there will be no cohesion between the basin and the frame.
  • this second type of frame piece 20 there is a normally circular protuberance 23 in the central part of the basin, with no significant effect on the structural strength, in which an extraction screw or hook is or can be housed.
  • the decreasing section can be conical or pyramidal, or stepped, either regularly or irregularly.
  • the concreting stage requires the lower spaces 8 located outside the assembly to be covered in order to prevent the poured concrete from getting into the interior (lower) zone of the technical floor, but without restricting the corresponding conduit characteristics.
  • the profile of the lower spaces 8 has been designed to include a set of tabs enabling a blocking piece 24 to be fitted.
  • the blocking piece 24 has an essentially identical section to that of the lower space in which this will be located, so that by means of the tabs set inside this lower space 8 the blocking piece 24 can be fitted into said unit 1 from below on the plane of the surface of the hollow space and at the same time, and after setting unit 1 in the floor its accidental withdrawal is practically impossible.
  • the blocking piece 24 includes a set of pre-cut zones 25 for allowing different wiring tubes or conduits through.
  • connection body 26 able to be fitted instead of a tile or covering slab of a technical floor which comprises a base 27 , that can be secured to the technical floor, for example by screwing this on, with a connection zone 29 .
  • This connection zone 29 is raised a few centimetres over floor level.
  • the connection zone 29 comprises a plurality of pre-cut areas 28 for fitting the corresponding connection bases.
  • the covering can be by means of assembled tiles or slabs.
  • the connection body 26 can also be fitted with means for assembly with the corresponding slabs or tiles.
  • the units 1 may have different heights depending on the application for which the technical floor is intended. For example, it will have to be higher if it has to contain drains than if only electrical wiring has to be allowed through.
  • the height of the frame 20 will also depend on the thickness of concrete required, and this will be determined depending on the strength characteristics required by the installation.
  • opening units 1 can be combined with other identical units not fitted with these hatches.
  • technical floors can be installed in building of several storeys or with limited free height. Particularly in these cases a technical floor should be installed in such a way that the weight, and in this case the layer of concrete poured in, is reduced as far as possible.
  • a body formed in a single piece made up of a set of units, at least one of these being openable, has been designed, so that apart from the angular spaces which will form the pillars of the assembly there are spaces for forming these pillars in multiple interior and perimeter zones other than the corners. This allows great strength through greater distribution of the loads.
  • the body described is as if at least one opening unit 1 were taken and possibly one or more non-opening units set adjacently, forming bodies of 1 ⁇ 2, 2 ⁇ 2, 2 ⁇ 3, 3 ⁇ 3 formed as a single piece.
  • a solution equivalent to the one in the present invention and which should thus be considered within its scope is that none of the pillars are set at the corners or the perimeter and the coupling between units or bodies of sets of units is done in places which are not crossed by said pillars.
