Definitions

  • the present invention relates to a glazing panel. More particularly, the present invention relates to a multi-walled glazing panel suitable for use as a roof light or like structure. The present invention also provides a method of attaching a multi-walled glazing panel to a support structure.
  • roof lighting enables daylight to be effectively transmitted or admitted into buildings.
  • One type of roof lighting includes at least one multi-walled glazing panel supported by a support structure, which is locatable on the roof of a building.
  • Such support structures generally comprise a plurality of bar members located at either side of the multi-walled glazing panel and which are adapted to receive such panels.
  • bar members are commonly referred to in the industry as glazing bars and come in various shapes and sizes. It is to be understood that such panels can be located on any part of a building or like structure.
  • a known type of multi-walled glazing panel 100 includes a plurality of, or at least two, horizontal sheet members 101, separated from one another by vertical interconnecting walls 102, such walls 102 defining channels 103 running along the length of the multi-walled glazing panel 100.
  • multi-walled glazing panels 100 of this type are made from the extrusion of a polycarbonate material, and the thickness of such panels can range from 4 millimeters up to approximately 30 millimeters.
  • a major advantage of this type of multi-walled glazing panel is that they provide good heat insulation and light transmission and consequently, can assist with savings in energy costs. Moreover, and as such glazing panels are extremely light in weight, less stress is exerted by them on the surrounding structures of the building to which they are attached and consequently, it is believed that they may actually extend the life of a building to which they are attached.
  • the present invention addresses the problem outlined above.
  • the sides of the multi-walled glazing panel of the present invention which are to be attached to the support structure, are reinforced, same is less likely to come free from the support structure when an object falls thereon. Therefore, it is believed that the present invention increases the overall safety of using such multi-walled glazing panels as part of a roof light or like structure.
  • same acts as a mechanical restraint and moreover, enhances the inherent rigidity of the multi-walled glazing panel, thereby increasing the resistance to the dislocation of the glazing panel from the support structure.
  • both of the above factors result in a high percentage of the energy of the falling object being transferred to, and absorbed by, the support structure, which can safely absorb such energy without the dislodgment of the glazing panel therefrom.
  • the sides of the multi-walled glazing panel which are attachable to the support structure are reinforced with reinforcement means which are locatable within the multi-walled glazing panel.
  • the reinforcement means comprises a bar of metal, preferably extruded commercial grade aluminium. It is to be understood that the bar may be of any other suitable material exhibiting the desired rigidity, for example, polycarbonate.
  • the reinforcement means is sized to fit snugly within a channel provided within the multi-walled glazing panel, but not too snugly so that same is difficult to insert into said channel. This has the advantage in that same is easy to locate within the glazing panel.
  • the reinforcement means is of such a size that it is concealed by the portion of the support structure to which it is fixed. This has the advantage in that the reinforcement means cannot be seen from either above or below and hence, does not affect the aesthetic qualities of the glazing panel, nor hinder the transmission of light therethrough.
  • a roof light incorporating a multi-walled glazing panel in accordance with the present invention.
  • 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 Figure 2.
  • 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.
  • 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.
  • 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.
  • 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.
  • a clearance hole or aperture is provided through the top of each jaw 21 and through the top layer of the glazing panel 10, followed by a tapping hole through the reinforcement bar 15.
  • Such an aperture is preferably provided on both sides of the glazing panel 10 in a central position along the length of each glazing bar 20 and immediately over the center of the reinforcement bar 15.
  • Fixing means 22, such as a self tapping screw is then driven into the assembly of the glazing bar 20, panel 10 and reinforcement bar 15, until the head of the screw 22 sits on the surface of the glazing bar 20.
  • such screw 22 is not tightened to such an extent that free thermal movement of the glazing panel 10 is hindered, that is, when fixed to its respective glazing bar 20.
  • U-profile capping members 25 are then placed at either end of the glazing panel 10.
  • the protrusion of the reinforcement bar 15 beyond the end of the panel 10 is intended to act as a restraint by contact with the U-profile capping members 25, thus preventing any sideways movement of the reinforcement bar 15.
  • a side of the panel 10 is locatable between a jaw or clamp portion 31 provided by a base member 35 and capping bar 34 of a glazing bar 30.
  • the panel 10 and reinforcement bar 15 are fixed to the glazing bar 30 via fixing means 32, such as a self-tapping screw, which passes through an aperture provided in a surface of a upper seal 36a into the panel 10 and reinforcement bar 15.
