Abstract

A roof structure comprises roofing sheets (102) supported between glazing bars (104) and has an eaves structure comprising an eaves beam (106) adapted for securing bars (104) at any desired angle, the eaves beam having relatively pivotable parts (116, 122) one of which has means for securing bolts (130) which secure glazing bars (104). The bolt-securing means may be a channel along which the bolts are slidable. <IMAGE>

Description

Title: Roofs DESCRIPTION This invention concerns roofs and, in particular, concerns conservatory roofs.

Conservatory roofs are often constructed these days from polycarbonate roofing sheets supported between glazing bars. Special arrangements are required for eaves of such roofs and it is such arrangements that are objects of this invention.

According to the invention there is provided a roof structure comprising roofing sheets supported between glazing bars and having an eaves structure comprising an eaves beam adapted for securing bars thereto at any desired angle, the eaves beam comprising first and second parts pivotable relative to each other, wherein one of said parts has means for retaining bolts which secure the glazing bars.

In the case of the eaves structure according to the invention it is preferred that the eaves beam has means for retaining securing bolts, such as in a channel thereof, to which bolts the glazing bars may be secured.

Preferably such channels are shaped whereby bolts may only be slid into position along a channel. The preferred channel has a longitudinal rib therein on which a slotted bolt head can locate. Also the channel edges preferably have inwardly extending lips to prevent withdrawal of a bolt past them.

Other preferred features of the invention will be apparent from the following exemplary description given with reference to the accompanying drawings, in which: Figure 1 is a section through a conservatory eave; and Figure 2 is a partially cut-away view of the eave of Figure 1.

Referring to Figures 1 and 2 of the accompanying drawings, a pitched conservatory roof is formed of parallel glazing bars 100 supporting polycarbonate roofing sheets 102 thereon and retained by PVC cappings 104. The glazing bars 100 are secured at their lower ends on an eaves beam 106.

The eaves beam 106 sits on a window profile 110 and comprises a first generally L-section part 112 one limb 114 of which sits on the window profile and the other limb 116 extends upwards. At its upper end the limb 116 has a hooked or curved formation 118 on which locates a cooperating formation 120 of second eaves part 122 so that the relative angle of the first and second parts to each other may be altered to suit the desired roof pitch.

The second eaves part 122 also has a channel 124 formed therein. The channel has an internal longitudinal rib 126 formed therein and has inwardly extending lips 128 so that bolts 130 can be retained therein. The bolts 130 have to be slid into position in the channel. The bolts 130 are secured through the glazing bars 100 by means of nuts (not shown) thereon.

On the inwards face of the first part 112 of the eaves beam are serrated projections 132 which locate into corresponding slots 138 of a cladding member 134.

On the outwards face of the part 112 is another serrated projection 140 into which locate gutter brackets 142.

The gutter brackets 142 also have a hooked part 144 that locates in the channel 124 of the eaves beam. At their other end the brackets 142 have a hooked portion 146 over which a hooked portion 148 of gutter 150 locates.

The gutter 150 at its other side locates in a space 152 provided in the brackets 142.

Finally, the glazing bars are capped at their ends by end plates 156.

Claims

1. A roof structure comprising roofing sheets supported between glazing bars and having an eaves structure comprising an eaves beam adapted for securing bars thereto at any desired angle, the eaves beam comprising first and second parts pivotable relative to each other, wherein one of said parts has means for retaining bolts which secure the glazing bars.

2. A structure as claimed in claim 1, wherein a first part of the eaves beam has a curved formation and the second part has a cooperating formation thereby enabling the relative angle of the first and second parts to each other to be altered to the desired roof pitch.

3. A structure as claimed in claim 1 or 2 wherein the bolts are retained in a channel of said eaves beam part.

4. A structure as claimed in claim 3, wherein the channel is shaped whereby bolts are slidable into position along the channel.

5. A structure as claimed in claim 4, wherein the channel has a longitudinal rib therein on which a slotted bolt head is locatable.

6. A structure as claimed in claim 3, 4, or 5 wherein the channel has inwardly extending lips.

7. A roof structure substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.
