Description

2354536 IMPROVED BUILDING SYSTEM The present invention is concerned with

improvements in or relating to building systems, and particularly, though not exclusively, to flooring systems, and related components.

In. situations in which it is required to lay upon an uneven substrate a floor arrangement having a level upper surface, it is well known to provide flooring devices which extend heightwise within a gap formed between the substrate and flooring supports therefor, the height of the flooring devices being selectable or adjustable according to the height of the gap at various appropriate locations.

Flooring panels are thus arranged to provide said required level surface and may comprise floor boards, panels or such like which may be supported by battens or other support means laid in a regular pattern across the floor area. It is, therefore, advantageous to provide a means for positioning the battens relative to the flooring devices which is compatible with the necessity to make adjustments to the height of the flooring devices where appropriate to accommodate unevenness in the substrate.

In traditional constructions it is common for concrete sub-floors to be uneven and outwith the relevant tolerances. There is thus generally a degree of stepping between adjacent units of the sub-floor and a measure of 2 longitudinal camber.

GB 2, 310, 227A and GB 2, 314, 351A (INSTAFIBRE) disclose a building component in combination with one or more spacers, the building component comprising a base element adapted to be positioned on a surface of a building structure and a pair of mutually spaced side members which project from the base element to define a longitudinal channel for receipt of a supporting batten to which a further surface layer may be secured, the building component being adapted to allow the insertion of each spacer between the base element and the supporting batten in a direction transverse to the longitudinal channel. In these documents one or both of the side members are adapted to deform resiliently in a direction transverse to that of the channel such that upon insertion each spacer is held within the building component by friction. It is noted that the building component may be formed from rubber crumbs. A number of disadvantages have become apparent in these components. For example, since friction is employed to hold the spacers in a component, such friction has to be overcome so as to insert each spacer. This may lead to repetitive strain injury of an installer. Further the rubber crumb component may flake leading to an untidy working area.

3 GB 2,321,07OR (DANSKIN) discloses a flooring component comprising a saddle member adapted to be positioned upon a support means provided between a substrate and a flooring member(s) to be supported above the substrate, said saddle member comprising a plate member, said plate member being provided with flange means extending substantially perpendicularly from marginal portions of a first surface of the plate member and adapted to engage said support means in use, and four L-shaped brackets extending outwardly of a second, opposite, surface of said plate member from positions extending inwardly of marginal portions of the plate member, each L-shaped member having a right-angled corner portion and being arranged so that said corners face each other in a spaced apart manner so as to define a cruciform channel therebetween.

Figure 1 shows of a saddle member, generally designated 2, for use in a building system according to a first embodiment of the present invention, moulded from suitable plastics material and comprising a plate member 4 a surface of which is provided with a downwardly extending flange means 6. It will be understood that the flange means 6 may be discontinuous if preferred. Upstanding brackets 8 are provided on an opposite surface of -the plate member 4, each bracket being L-shaped as may be seen from Figure 2 and arranged so as to provide a cruciform channel 10.

The brackets 8 which are, in this advantageous embodiment, moulded integrally with the plate member 4 may be of any selected height, A, B or C as will be explained below.

In use, the channel 10 will receive a through-batten, shown at 12 in broken lines in Figure 2 and in full lines in Figures 5 to 6 and where required will receive end 14 portions of one, or two, batten (s) 14 which will each abul- a side surface of the through-batten 12. As may be seen in Figure 6, the battens 12, 14 are suitable for supporting conventional floor boards 16.

The flange means 6 are provided in order to engage with an upper portion of a support means which may be in the form of a panel 18 as shown in Figure 6, or alternatively one or more stools, e.g. timber battens. A layer of resilient material may be provided on a lower surface of the panel 18 to contact the substrate S beneath.

Alternatively the panel 18 may be in direct contact with the substrate and optionally a layer of resilient material may be laid in the cruciform channel 10.

The substrate S is, e.g. a floor of a building structure, and it may therefore be necessary to vary the height of the assembly described above, so that an upper surface of the floor boards 16 will be substantially horizontally level. Packing pieces 22 are therefore provided to be placed in the channel 10 to a depth sufficient to compensate for the unevenness of the substrate. As can be seen in Figure 5, where a through batten 12 is to be supported, one or more rectangular packing pieces 22 may be suitable. At least one recess or hole 7 on a contacting surface 4 of the saddle member 2 is provided so as to receive a nipple 13 extending from packing piece 22, illustrated in Figures 3 (a) - (c). The is recess 7 and nipple 13 co-operate to locate the packing piece 22 at a pre-determined position relative to the saddle member 2. In this embodiment the nipple 13 is cylindrical with a diameter suitable for engaging in cylindrical recess 7. Furthermore, the packing piece 22 also has a recess 15 designed to engage a further nipple 13 extending from a second packing piece 22, as depicted in Figures 5 and 6.

In this way a number of packing pieces 22 may be placed in combination within the saddle member 2 to achieve levelling of uneven sub-floors. As no gluing of packing pieces 22 is normally required site installation is faster than alternative systems. Packing is generally permissible up to 5 mm below the top of shoulders of the saddle member 2.

As can be seen f rom Figure 2, in this embodiment the batten 12 runs perpendicular to the packing pieces 22.

However, it will be appreciated that the batten 12 may in some instances be run parallel to the packing pieces 22.

The packing piece 22, as illustrated in Figure 3 (b), may have a chamfered edge 17 to facilitate ease of offering of the packing piece 22 between the batten 12 and saddle member 2 or other packing piece 22, and thereby assist in placing the packing pieces 22 in the required positions.

Alternatively, the edge of the packing piece 22 may be wedged shaped 19 as depicted in Figure 3(d) 16 In areas where there is a particularly deep depression in the substrate, it may be found that so many packing pieces 22 are needed that the channel 10 is rendered unduly shallow unless the brackets 8 are- selected to have sufficient height, referring to Figure 1, say C rather than A or B. Saddle members 2 may be manufactured by a suitable moulding technique for example, with appropriate portions of the mould cavity blanked off in the regions of the brackets 8 to produce brackets 8 of a height corresponding to heights A, B or C as required. If preferred, where brackets 8 are moulded to the height C, reinforcement may be provided outwardly of the bracket 8 to resist unwanted flexing, as discussed in GB,321,070A (DANSKIN) In use, there is provided a plurality of building components each comprising a saddle member 2 including a channel 10 capable of receiving at least one packing piece 22. A plurality of packing pieces 22 are also provided, surfaces of the saddle member 2 and adjacent packing piece 22 and/or surfaces of adjacent packing pieces '22 which oppose one another, in use, being provided with interengaging means 7, 13, 15. A plurality of building components are positioned in a plurality of spaced rows over a surface of a building structure with said building components spaced longitudinally within each of the rows and the channels 10 of the building components of each row are aligned so as to define a longitudinal batten path.

17 One or more support battens 12 are placed along the batten path and one or more packing pieces 22 transversely inserted between the support battens 12 and the building components into the channels 10 such that the interengaging means 7, 13, 15 co-operate so as to locate each packing piece 22 at a predetermined position relative to the saddle member 2 or adjacent packing piece 22. One or more elements of a surface layer 16 are then secured to the support battens 12 to form the floor, wall or ceiling. In this embodiment the packing pieces 22 are advantageously offered into the channel 10 transversely to the batten 12.

However, it will be appreciated that in - certain circumstances it may be desirable to offer the packing pieces 22 into the channel 10 parallel to the batten 12.

is Referring now to Figure 7, there is shown a saddle member 2a, for use in a building system according to a second embodiment of the present invention. The saddle member 2a is substantially the same as the saddle member 2 of Figure 1, like parts being denoted by the same integers but suffixed with "a". However, saddle member 2a does not possess recess 7.

The packing pieces 22a, illustrated in Figures 8(a) (c), have extended lips 19a designed to overlap the edges of contacting surface 4a in channel 10a so as to locate the packing piece 22a at a pre-determined position relative to the saddle member 2a. The extended lips 19a are designed 18 so one end is complementary to the other thus, when a second packing piece 22a is placed on top of the first in an opposing orientation in a horizontal plane, the lips 19a of the adjacent packing pieces 22a engage and co-operate so as to provide an intimate contact between the packing pieces 22a thus locating the second packing piece. 22a at a pre-determined position relative to the first packing piece 22a as illustrated in Figures 9, 10 and 11. Moreover, it is to be understood that the saddle 2 depicted in Figures 1 and 2 may also be used in conjunction with packing pieces 22a.

Referring now to Figures 12(a) to 15, there is shown a building component for use in a building system according to a third embodiment of the present invention. As illustrated in Figures 13 to 15, saddle 2b is substantially similar to the saddle depicted in Figure 1, like parts being denoted by the same integers but suffixed with 'b' The packing piece 22b illustrated in Figures 12 (a) (c) incorporates the features of packing pieces 22 and 22a, so as to provide a nipple 13b, a recess 15b and lips 19b.

These are all formed so as to co-operate in a manner as described for the first and second embodiments of the present invention.

Referring to Figures 6, 11 and 15, a flooring member 16, 16a, 16b is provided. The flooring member 16, 16a, 16b may comprise 18mm or 22mm Type C4 Moisture Resistant Grade 19 chipboard manufactured to BS S669, tongued and grooved on all four sides and supplied in sheet size 2400 x 600mm, or alternatively WBP plywood tongued and grooved all round supplied in sheet size 2400 x 600mm.

The battens 12, 12a and 12b may be softwood support bearers and are placed within the saddle 2, 2a, 2b to support the flooring members 16, 16a, 16b and can be preservative treated if required. They are normally supplied in 1800mm lengths for ease of handling and the standard bearer heights are 22mm, 36mm and 52mm.

The saddle plate member 4, 4a, 4b may be 13 x 97mm in size and may be manufactured from tough injection moulded plastic with three different shoulder heights to accommodate the three standard batten 12, 12a, 12b sizes.

The ingenious design of the saddle plate 4, 4a, 4b means that it can also support cross noggins at access panels and perimeter bearers. The saddle plate 4, 4a, 4b may be glued on top of the resilient saddle support 18, 18a, l8b.

The packing pieces 22, 22a and 22b may be rigid, conveniently dimensioned to be a snug but loose fit within the channel 10 and may also be manufactured f rom tough injection moulded plastic.

The saddle supports 18, 18a, 18b may be variously manufactured from WBP plywood, oriented strand board (OSB) or softwood depending on the required floor height. All may have 9mm thick resilient acoustic foam adhered to the underside to assist impact sound resistance. A standard resilient saddle support 18, 18a, 18b height is 15mm inclusive of foam.

The building system of the present invention is particularly advantageous in providing partial access to services. The preferred saddle plate 4, 4a, 4b is designed to accept battens 12, 12a, 12b running in both directions where necessary to provide secure support for access panels. Access panels may be square edged and supported along all edges by battens 12, 12a, 12b. The panels may be secured, e.g. by screws.

The packing pieces 22, 22a and 22b assist in achieving the levelling of uneven sub-floors. The ingenious design of the various embodiments of the saddles 2, 2a and 2b and is packing pieces 22, 22a and 22b allows insertion of the packing pieces from the sides of the saddles 2, 2a and 2b, perpendicular to the length of the batten 12, 12a, 12b.

The advantage of this design is that the removal of the batten 12, 12a, 12b from the channel 10 in the saddle 2, 2a, 2b to insert packing pieces 22, 22a, 22b is not necessary; raising the batten 12, 12a, 12b to a height sufficient to accommodate the packing piece 22, 22a, 22b is only required. Moreover, the various embodiments of the packing pieces 22, 22a, 22b hereinbefore described assist in locating the packing pieces 22a, 22b, 22c at a pre determined position relative to the saddle member 2, 2a, 2b 21 or adjacent packing piece 22, 22a, 22b and are held in place without the need for adhesives.

Additionally, the design allows the packing pieces 22, 22a, 22b to be inserted and removed with relative ease by the user. This is particularly important for using the system on a large scale and repeated adjustments of the level of the flooring is necessary. The system, therefore, greatly reduces fatigue and the possibility of causing repetitive strain in3ury to the user.

Referring now to Figures 16 (a) to (c), there is shown a packing piece 22c for use in a building system according to a fourth embodiment of the present invention. As illustrated in Figures 16 (a) to (c), the packing piece 22c is substantially similar to the packing piece 22 depicted in Figures 3 (a) to (c), like parts being denoted by the same integers but suffixed with "c".

The packing piece 22(c) illustrated in Figures 16(a) to (c) incorporates a pair of protrusions 13c provided on a first surface of the packing piece 22c, and a pair of recesses 15c provided on a further surface of the packing piece 22c. Respective protrusions 13c oppose respective recesses 15c.

In use a plurality of packing pieces 22c may be provided for use with a suitably adapted saddle member (not shown) having recesses formed in a surface thereof for the acceptance of protrusions 13c from a first packingpiece 22 22c. As will be appreciated, since the packing piece 22c is substantially symmetrical, the orientation of the packing piece 22c when presented to the channel of the saddle member is immaterial since either end of the packing piece 22c may be inserted into the channel and the protrusions 13c of the packing piece 22c received either by the saddle or by an adjacent lower packing piece 22c.

Referring now to Figures 17(a) to (c), there is shown a packing piece 22d for use in a building system according to a fifth embodiment of the present invention. As illustrated in Figures 17 (a) to (c), packing piece 22d is substantially similar to the packing piece 22 depicted in Figures 3(a) to (c), like parts being denoted by the same integers but suffixed with "d".

is A similar advantage to the packing piece 22c of the previous embodiment is provided in that since the packing piece 22d is substantially symmetrical in nature, then the direction of insertion of the packing piece 22d into the channel of the saddle member is immaterial in stacking a plurality of packing pieces 22d. It will be appreciated that this advantage is of great benefit, in use, in that an installer does not require to carefully check the orientation of the packing piece 22c or 22d when presented to the saddle member.

Referring now to Figure 18, there is depicted a side view of a number (in embodiment four) of packing pieces 22d 23 of varying thicknesses. The plurality of packing pieces 22d comprise a set of packing pieces according to a fifth embodiment of the present invention. Each packing piece 22d of Figure 18 is of a different thickness, ani also of a different colour.

In use, therefore, a plurality of such packing pieces 22d may be provided so as to f orm a set of packing pieces 22d for use in a building system. The set of packing pieces 22d comprising a plurality of subsets, each subset comprising at least one packing piece 22d, the packing pieces 22d of each subset being of the same colour, and the packing pieces 22d of different subsets being of different colours. Thus the first, second, third, and fourth packing pieces 22d of Figure 18 may be of thicknesses of is 3mm, 4mm, 5mm, and 10m respectively, the first, second, third, and fourth packing pieces 22d further being of colours a, b, c, and d, respectively. Colours, a, b, C, and d, will be different and may be selected from, for example, green, blue, red, yellow, black, brown or white.

Provision of a colour coded set of packing pieces 22d may assist in ease of installation since a packing piece 22d of a particular colour will be easily recognised by an installer as a packing piece 22d of a particular thickness.

Referring now to Figures 19 to 23, there is shown a saddle member 2e and plurality of packing pieces 22e, for use in a building system according to a sixth embodiment of 24 the present invention. The saddle member 2e and packing pieces 22e are similar to the saddle member 2 and packing pieces 22 of Figures 1 to 6, like parts being denoted by the same integers but suffixed with "e".

As can be seen from Figure 20, saddle member 2e is provided with a pair of substantially symmetrically disposed holes 7e (or alternatively recesses). Further each packing piece 22e is provided with a corresponding pair of substantially symmetrically disposed protrusions 13e. Further on a surface opposing the protrusions 13e each packing piece 22e is provided with a corresponding pair of recesses 15e.

It will be appreciated that this arrangement allows each packing piece 22e to be inserted into the channel of is the saddle 2e in one of two opposing directions, such that an installer does not require to select a particular direction of insertion thereby leading to ease of installation.

It will be appreciated that various modifications may be made within the scope of the invention, and in particular that the invention may be employed in the forming of floors, walls and/or ceilings. For example, the interengaging means may comprise at least one recess or hole carried on the packing piece and at least one corresponding nipple or other suitably shaped protrusion formed in the saddle.
