Abstract
A prefabricated roof is made of a number of pieces for lightness in installation, the pieces being trays connected together with engaged ribs and grooves in edge flanges. These ribs and grooves ensure alignment and help in providing weather tight sealing. Insulation 54 may be provided in the trays and a bead of sealant 42 may be provided between a rib and groove. <IMAGE>
Description
ROOFS
This invention relates to pre-fabricated roof units as used for domestic home extensions such as porches or garden rooms. These are conveniently made of material known as GRP, that is synthetic resinous materials reinforced by glass fibres in felt-like cloth layers.
These materials can be laid into moulds if required and can be sandwich filled with insulation materials, and then cured so as to give a virtually finished article comprising a ceiling and roof with a facia ready for assembly in situ. The weight factor and also the need to avoid severe flexing in installation may call for a large number of workmen solely for the operation of lifting the pre-fabricated roof from ground level to the required position. The weight also restricts the size which is possible. The object of the invention is to solve these problems.
According to the invention, a pre-fabricated roof comprises a plurality of separate units adapted to be assembled together in situ to form an effectively one piece roof, and characterised in that each unit comprises at least one flange extending along the length or width of the unit, each flange of one unit abutting a corresponding flange of the next adjacent unit when the roof is assembled, and each two said adjacent flanges being provided with inter-engageable male and female parts which when so engaged at least assist in alignment of the two adjacent flanges.
Preferably each unit has a facia along the edge oi edges which are part of the exposed periphery of the assembled roof, and said flanges are along the edge or edges which extend across that periphery from one side to the other, and the flanges and facia are of similar height. Then, each unit is a tray-like piece comprising a base - which effectively forms the ceiling of the room when the roof is installed, with an upstanding flange about the entire periphery. The tray may collect rain water upon its entire area and this may be channelled by a gully or gutter groove provided in the tray. Adjacent trays may be bolted together so that a pair of flanges are face-to-face; one flange may have a rib along part of its length and the other a groove likewise positioned and aligned, so that when the rib is in the groove the flanges are known to be aligned.
According to an important feature of the invention the rib and grooves are of different cross section and not entirely complementary, so that a bead of sealant can be laid in the groove prior to assembly, and when the bolts or like are tightened, this will trap a known cross-section of the sealant to make a good seal between the two flanges. Preferably the groove is arcuate e.g.
semi-circular and the rib is partly of the same shape and dimensions but has a secant-like flat so that a gap will exist between the flat on the rib and the centre of the arc of the groove, to receive the sealant.
The rib and groove may extend along a straight line parallel to the side edges of the flange i.e. the top and bottom of the flange when the roof is in use, and according to another feature of the invention the terminal portions of the rib and groove are inset from the ends of the flange; this makes accurate lengthwise alignment easier in assembly. Preferably the flanges are pre-drilled for the bolts in the precise positions needed for accurate assembly as a further aid to correct alignment.
The material of each tray-like part may be patterned to provide ceiling ornamentation; the upper side of each tray may have gravel or like chips bonded in during manufacture.
One embodiment of the invention is described with reference to the accompanying drawings wherein:
Figure 1 is an exploded view of a roof;
Figure 2 is an enlarged scale fragmentary perspective view, also shown in the parts exploded;
Figure 3 is a further enlarged section showing joint parts;
Figure 4 is similar to Figure 3 but showing the assembled joints; and
Figure 5 shows a modification.
In the drawings, Figure 1 shows three pieces which are used to make a roof. Each is a shallow tray. Part 10 is a substantially semi-circular tray, to be assembled to a series of like rectangular trays 12 14. The semicircular tray will have only one ribbed or grooved flange 16 extending diametrically and the facia 18 about the remainder of its periphery may be made ornate to give a finished look to the roof from the exterior of the building. Each of the rectangular trays will have the same ornate appearance on their facias 20 at two opposite end edges to be aligned with ends of the semi-circular arc, and the rib and groove on the two other edge flanges 24-30. Any required length may be made by assembly together of sufficient units 12 to provide the required length of roof.Unit 14 could be identical to unit 12 although as illustrated it differs by the provision of an integral rain water drain connection 32. Each unit has apertures 34 to be connected in series to allow rain to drain from all of the trays through the connection 32 to a down spout, not shown.
Turning now to the joint features, each flange has a rib or groove arranged for automatic alignment of the units. Figure 2 shows how the rib and groove terminate short of the ends of the flange for longitudinal alignment, and also the holes 40 for the fixing bolts and nuts.
Figure 3 shows a bead of sealant 42 laid in the groove, and Figure 4 shows it squeezed into a film over a substantial area to make the seal. Capping strip 44 improves appearance and provides further sealing against weather.
Figure 5 shows the mentioned modification in which the groove 50 is larger than the rib 52 in order to trap a more substantial fillet of sealant in the groove.
In order to provide thermal insulation, blocks of suitable insulant 54 may be infilled or laid in the trays, before or after the GRP is cured. The covers 56 may be further GRP material laid on the insulant and rain water gullets. extending between the openings 34 may be formed or provided in the covers. In one possibility the insulant extends over the whole of the area of the roof except the gulley.
Claims (4)
1. A pre-fabricated roof comprising a plurality of separate units adapted to be assembled together in situ to form an effectively one piece roof, and characterised in that each unit comprises at least one flange extending along the length or width of the unit, each flange of one unit abutting a corresponding flange of the next adjacent unit when the roof is assembled, and each two said adjacent flanges being provided with inter-engageable male and female parts which when so engaged at least assist in alignment of the two adjacent flanges in two directions namely along the length and width of the flanges.
2. A roof as claimed in Claim 1 wherein each rib and groove terminate short of the ends of the flange in or on which it is provided.
3. A roof as claimed in Claim 1 wherein the rib and groove are of different cross-sections.
4. A prefabricated roof system substantially as described with reference to the drawings.
