Definitions

  • This invention relates to floor panels, particularly of the kind used in industrial situations, such as in the provision of gratings supported on structural elements, in the provision of walkways, platforms, and access flooring, hereinafter referred to as a floor panel of the kind specified.
  • One kind of floor panel of the kind specified comprises longitudinal beams, conventionally of T-section secured together at successive positions along the length by transverse bars to provide a transversely and longitudinally extensive grating.
  • This construction is utilised in the provision of open flooring, in which the longitudinal beams bear downward load to provide a grating, whilst the transverse bars are intended primarily to hold the longitudinal beams in the required relative positions.
  • Such a floor panel is disclosed in our UK Patent No. 2036149 (WO-A-78/00002).
  • a floor panel of this type suffers from the disadvantage that it is necessary to assemble the floor panels, and this is a time consuming operation.
  • CA-A-989134 is an assembled structure made up of a plurality of adhesively secured together assembled components. It discloses flooring made up of a plurality of "grate” sections, each "grate” section being assembled from a plurality of relatively narrow T-shaped flooring members, which may have one or two vertical support members, in which the floor members must be assembled together and held to tie bars by adhesive. The "grate” sections are joined together by separate clips. Such individual flooring members are described as being made by pultrusion. The flooring suffers from the same disadvantages as discussed hereinbefore and in particular requires assembly from a plurality of components and application of adhesive.
  • EP-A-413 500 is another assembled structure made up of a plurality of adhesively secured together components. It discloses a building system made by pultrusion having a curved top surface with two opposed side walls and a plurality of shorter ribs. It is generally unsuitable for use as a floor panel which is transversely extensive as it is supported only by opposite side walls. The T-shaped shorter members are assembled, by sliding engagement, with transverse stiffeners. In all cases it is intended that the described wall member is connected via separate connector plates and adhesive to other identical wall members to provide a transversely extensive floor panel.
  • EP-A-108 576 discloses another assembled structure made up of a plurality of planks which must be assembled to adjacent planks using separate connector members to provide a transversely extensive floor panel.
  • the individual planks are made as a rigid hollow structure filled with plastic foam, although the walls are made of pultruded material.
  • Another floor panel of the kind specified utilises moulded floor panels, the size of which is limited essentially by the size of moulding it is possible to make economically.
  • an elongate floor panel comprising a plate part having beam parts depending downwardly from, and integral therewith, the panel having been moulded in one piece by a pultruding operation, characterised in that the plate part is transversely and longitudinally extensive having an upper surface which provides a generally planar and continuous floor surface and said beam parts comprise a pair of end longitudinally extending beam parts and a plurality of intermediate longitudinally extending beam parts, the beam parts being of equal depth and each pair of adjacent beam parts defining therebetween a channel which extends from end-to-end of the beam parts, the end beam parts having each means for the connection with a contiguous panel.
  • the panel may have end beam parts having a configuration whereby a tongue portion of one panel can be received in a groove portion of an adjacent panel.
  • the panel may be provided with a longitudinally extending groove portion on one side and a longitudinally extending tongue portion at the other side whereby the tongue portion and groove portion of one panel may interengage with a groove portion and tongue portion respectively of two other adjacently juxtaposed panels to transfer load between the adjacent panels.
  • Intermediate longitudinal beam parts may be of inverted T-shape in cross-section, a stem of the T is being integral with the plate part and a head of the T providing oppositely directed flanges at the ends of the beam parts remote from the plate part.
  • the upper face of the floor surface is provided with longitudinal ribbing or other protruberences, to improve grip.
  • the plate part may be provided with a plurality of apertures intermediate the beam parts.
  • the apertures may be punched apertures.
  • the panel may comprise fibre reinforced synthetic plastics material with the fibres aligned or substantially aligned in the longitudinal direction of the panel thereby improving the strength of the panel.
  • the pultruding operation may cause the fibres to become aligned or more aligned in the longitudinal direction.
  • the reinforcing fibres may comprise uni-directional rovings to provide properties in the longitudinal direction of the member and continuous strand mat to provide transverse properties.
  • the plastics material may comprise polyester or vinylester resin and may also comprise at least one of filler, pigments, curing agents and processing aids as appropriate and ultra-violet inhibitor.
  • the panel may have a surface veil of polyester non-woven fabric which encases the fibre reinforcement and provides a layer of resin at the surface of the panel.
  • the veil may be capable of providing additioal protection against ultra-violet degradation, preventing fibre blooming and increasing corrosion resistance.
  • the plate may comprise from the top surface downwardly,
  • the filaments and the rovings may comprise glass filaments and rovings respectively.
  • a floor according to the first aspect of the invention wherein the or each panel is supported on supports with the beam parts lowermost and engaging the supports and with the floor surface uppermost.
  • the floor panel shown in Figure 7, which is not part of the claimed invention, comprises a plurality of elongate bars 10 secured together at spaced intervals by transverse bars 12, the upper limb 11 of the longitudinal beams cooperating together to provide a floor surface having gaps 13 between adjacent longitudinal beams.
  • an elongate floor panel 20 is provided, having been made in one piece by a pultruding operation, from glass fibre reinforced plastics material.
  • the panel 20 comprises a transversely and longitudinally extensive plate part 21 having an upper surface 22 which provides a generally planar and continuous floor surface.
  • a plurality of longitudinally extending beam part 23, 23 a , 23 b are arranged.
  • first and second end beam parts 23 a , 23 b are of the same shape which, in end elevation and in cross-section, is of inverted T-shape each having a vertically downwardly depending stem 24 formed integrally at one end with the plate part 21 and at the lower end a transversely extending head 25.
  • the first beam part 23 a has a configuration so as to provide a longitudinally extending rib or tongue portion 26 whilst the second end beam part 23 b has a configuration to provide a longitudinally extending groove portion 27. Accordingly, a tongue portion 26 of one panel 20 can be received within the groove portion 27 of an adjacent panel so that a load can be transferred between adjacent panels.
  • Suitable clip means may be provided to clip interengaged end beam parts 23 a , 23 b together or any other suitable means may be provided to join adjacent panels together, or separate joining means may not be provided, reliance being placed on the fixing of the panels to a support structure to maintain the parts in a desired juxtaposition.
  • the beam parts 23, 23 a , 23 b provide resistance to deformation of panel part 21 under load.
  • Elongate ribs 28 are provided on the upper surface 22 to improve grip although, if desired, the other patterns of ribbing or other grip providing means may be provided, or indeed omitted in any particular application.
  • a plurality of apertures 29 are provided distributed throughout the extent of the plate part 21, as shown in Figure 1.
  • each aperture 29 is identical and comprises semi-circular longitudinally opposite ends interconnected by parallel side wall parts.
  • Provision of apertures permits drainage of water from the panel and also reduces the weight of the panel.
  • the apertures 29 are made by punching and each aperture in a row may be punched at the same time and thus a relatively rapid rate of production may be achieved. If desired, suitable sealant may be provided to the walls of the punched apertures.
  • the panel is arranged to be supported on a support structure 30 with the undersurface 31 of the heads 25 engaging the upper surface of the support structure 30.
  • a fixing clip assembly shown generally at 32 in Figure 5, is provided to fix the panel to the support 30.
  • the clip assembly 32 comprises a glass fibre reinforced plastic holder plate 33 which engages the upper surface 34 of flanges 35 of the heads 25.
  • a stainless steel bottom clip 36 is clamped beneath a flange 37 of the support structure 30 by a screw 38 and nut 38 a , access to the head 39 of the screw being provided through one of the apertures 29.
  • To assemble the fixing assembly the screw 38 is inserted through the holder plate 33 and the stainless steel bottom clip 36 and the nut 38 a engaged with the screw.
  • the assembly is then slid along the flanges 35 to the desired location and then a plodring, not shown, may be positioned on the support 30.
  • the fixing assembly 32 is then slid into position, as shown in Figure 5 a and then the screw 38 is rotated with a screwdriver from above through the aperture 29 with nut 38 a being prevented from rotation by the configuration of the bottom clip 36.
  • any other suitable means for holding the panel to a support structure may be provided.
  • the plate part 21 has the following structure. Starting at the top surface 22, there is a 20g/m 2 chemical resistant surface veil 40 of a polyester non-woven fabric to encase the glass fibre reinforcement and add a layer of resin to the surface. This is to provide additional protection against ultra-violet degradation, to prevent the fibre blooming and increase corrosion resistance.
  • the uppermost mat 41 a extends downwardly over the side edges 43 of the plate part 21 and over a majority of the tongue part 26 and groove part 27.
  • a further 600g/m 2 E glass continuous filament mat 44 c is overlapped by an end part of the mat 41 a in the groove 27 and extends around the head 25 of the associated beam part 23 b and provides a third mat for the plate portion 21 beneath the mats 44 a , 44 b .
  • a further similar mat 44 d extends around the next adjacent beam part 23 and overlaps an end part 44 c ' of the mat 44 c , the mats 44 a , 44 b being deflected as shown to make the undersurface 47 of the plate part 21 between the beam parts 23 planar.
  • An end part 44 d ' of the mat 44 d is similarly overlapped by a further mat 44 e which extends around the next adjacent beam part 23 and this is repeated across the transverse extent of the panel.
  • a penultimate beam part 23 has a further mat 44 f .
  • the uppermost mat 41 a extends past the majority of the tongue portion 26 and overlaps an end part of a further mat 44 g which overlaps an end part 44 f ' of the mat 44 f .
  • a polyester surface veil 40 extends over the whole of the external surface of the panel including the beam parts.
  • Each beam part 23, 23 a , 23 b in addition to the polyester mats 44 c - f previously described, comprises uni-direction E glass rovings 45 to fill.
  • the above mentioned mats and rovings reinforce a suitable synthetic plastics resin such as polyester or vinylester resin which may also comprise pigment, curing agent and processing agent as appropriate, as well as ultra-violet inhibitor to impart resistance to the effects of ultra-violet radiation.
  • a suitable synthetic plastics resin such as polyester or vinylester resin which may also comprise pigment, curing agent and processing agent as appropriate, as well as ultra-violet inhibitor to impart resistance to the effects of ultra-violet radiation.
  • the panel may have, for example, three mats above the rovings or may contain more than four and three mats respectively above and below the rovings. If desired more layers of rovings may be provided between different mats.
  • the beam parts may have more mats distributed as desired.
  • the mats and rovings may be made of other suitable material.
  • the panels described hereinbefore have a cross-sectional area of approximately 5200mm 2 and may be 500mm wide, 40mm deep and 6 metres long.
  • the panel has a weight of approximately 20kgs per square metre which is considerably lighter than the equivalent steel panel, which is of a weight of approximately 81kgs.
  • the above mentioned 20kg weight is the weight prior to the provision of apertures 29. Of course, the weight is further reduced when the panel is thus slotted.
  • the panel of the present invention being a one-piece construction, has the necessary strength and deflection resistance without any need to assemble individual components, thereby avoiding problems hitherto associated with jointing.
  • the invention provides the benefit of a moulded floor panel, with the benefits of an elongate assembled floor panel, without the need for assembly, particularly in that gaps between the longitudinal beams is obviated.
  • the panel is made by a pultrusion process in which the mats and rovings are fed into a pultrusion die together with the resin, there being means continuously to draw the mats and/or rovings through the die.
