DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As illustrated in FIG.
2, a multi-walled polycarbonate glazing panel 10 in accordance with the present invention includes a plurality of horizontal sheet members 11, separated from one another by vertical interconnecting walls 12, such walls 12 defining channels 13 running the length of the multi-walled glazing panel 10.
Additionally, and in order to reinforce the sides or side portions of the panel 10 which are to be attached or supported by a support structure, such as a glazing bar, same is further provided with reinforcement bars 15 which are insertable into channels 13 located at either side of the panel 10.
For illustration purposes, only one of such bars 15 is shown in FIG.
2.
As illustrated in FIGS.
3 and 4, each side of the panel 10 is locatable between the jaw or clamp portion 21 of a glazing bar 20 of the interlocking type, sold by us under the name "MULTI-LINK-PANEL INTERLOCKING MODULAR GLAZING SYSTEM", which is the subject of our European Patent No.
0473321.
As shown, the panel 10 and reinforcement bars 15 are fixed to the glazing bar 20 via fixing means 22, such as a self tapping screw, which passes through an aperture provided in a surface of the jaw 21 into the panel 10 and reinforcement bar 15.
As shown in FIG.
4, the bar 15 can be located in either of the channels 13 directly adjacent the glazing bar 20.
Additionally, the bar 15 is located within the confines of the jaw 21 of the glazing bar 20 and hence, is concealed.
Once each side of the glazing panel 10 is fixed to its respective glazing bar 20, via reinforcement bars 15, a U-profile capping member 25 is placed on either end of the glazing panel 10.
In order to install a multi-walled polycarbonate glazing panel 10 as shown in FIGS.
2 and 3, a reinforcement bar 15 is inserted into a channel 13 at each side of the panel 10 which are to be fixed to the glazing bars 20 of a support structure.
It is preferable that the length of the reinforcement bar 15 is selected such that when located within the glazing panel 10, same protrudes at both ends thereof, preferably by about 4 mm
