Description

A GLAZING BAR AND A METHOD FOR USING THE GLAZING BAR

BACKGROUND

The disclosure herein relates to roof covering, more specifically to glazing bars and installing a glazing with the glazing bars.

A glazing bar is a bar or a rigid supporting strip between adjacent panes of glass or similar thin panels, configured to be attached between two adjacent beams. The glazing bar has usually a uniform profile along its length.

Traditionally glazing bars are first attached to a roof beam. A conventional glazing bar supports the glass panes that are lowered onto the glazing bar. The assembly is completed by a top bar that is attached to the glazing bar from above, thereby clamping adjacent glass panes to the glazing bar. Much of the work is done from above the roof. A worker must operate on a sloped, sometimes slippery roof surface. The glass panes may not be suitable to withstand worker’s weight. Therefore assembling a glazed roof from above requires a lot of protective gear and fall protection.

US4189882A discloses roofing means including a roof panel. Means are provided for securing the roof panel onto a roof frame including elastic clamping

N means joining the panel in tensioned relation to the frame and a deformable 5 elastic sealing member secured between the clamping means and the panel = and covering the clamping member.

S SUMMARY

This summary is provided to introduce a selection of concepts in a simplified form that will be further described below in the detailed description. This summary is intended to neither identify key features or essential features of the claimed subject matter nor to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all of the disadvantages noted in any part of this disclosure.

A glazing bar and a method for using the glazing bar are disclosed hereinafter.

The glazing bar has a first groove configured to receive a glass pane. The glazing bar has a base and a first extension extending downwards, providing an

L-shaped support against a roof beam.

The glass pane may be inserted to the first groove by pushing it through a sealing that provides sufficient grip to the glass pane. A second glazing bar is attached in a similar manner to an opposite edge of the glass pane, thereby forming a glazing assembly. The glazing bars provide an inverted L-shaped support on both sides of the glass pane.

The glazing assembly may be assembled at a ground level. The glazing assembly may then be lifted onto adjacent roof beams, as the inverted L- shaped supports keep the glazing assembly in place. Alternatively, the glazing assembly may be pushed up onto the adjacent roof beams down from the eaves’ side. The glazing assembly is secured to the roof beam from below, by a fastening device through the first extension to the roof bar, for example by a coach bolt or screw.

Adjacent glass panes may be assembled into similar glazing assemblies and pushed onto the roof beams. In some embodiments, the arrangement leaves 3 portion of the roof beam open upwards. This is solved by a finishing strip that 3 25 may be pushed into a strip grooves that are at a top portion of the glazing bar, o opposite to the first groove. The strip grooves of two adjacent glazing bars over one roof beam are facing each other. The finishing strip may be pushed

E simultaneously to both strip grooves. The finishing strip prevents rain, dirt or

J debris falling onto the roof beam. 3 30 In one embodiment, the glazing bar comprises two adjacent extensions, configured to provide inverted U-shaped support for the roof beam. The glazing bar comprises two opposite grooves for glass panes, enabling assembly of larger roof portions at once. The assembly comprising multiple glass panes may be pushed onto multiple roof beams from below, from the eaves’ side.

The pane may be made of glass, plastic or any durable light-permeating sheet material. In one embodiment the pane is a corrugated sheet of PVC light covering. Examples of applications are glazed terraces or patios.

The assembly method may be completed without accessing the rooftop, using only light scaffolding or ladders. The glazing bar described herein enables assembling glazing over one storey buildings in a simplified and safe manner as the worker may operate from below the roof glazing, without stepping on the roof. Some examples of panes may be slippery or not suitable to be walked on.

Many of the attendant features will be more readily appreciated as they become better understood by reference to the following detailed description considered in connection with the accompanying drawings. The embodiments described below are not limited to implementations which solve any or all the disadvantages of known glazing bars.
