Apparatus for and a method of attaching items to curtain walling

A method of attaching items such as solar shading to curtain wall mullions of the kind herein defined, comprising the steps of:

• (a) selecting apparatus for attaching items such as solar shading to curtain wall mullions of the kind herein defined, the apparatus comprising:
• a bracket having a generally U-shaped formation at one end for fitting over the generally U-shaped formation of the glazing bar of a mullion,
• a substantially planar portion which, when the bracket is fixed to the mullion, projects forwardly of the glazing bar and in use between two adjacent glazing units, and
• a seal locating formation projecting laterally of the substantially planar portion, the generally U-shaped formation comprising a web-portion and two parallel or substantially parallel side portions, the web portion having an aperture therein above and/or below the substantially planar portion for receiving a self-tapping screw which can, in use, extend through the aperture and engage with the groove in the U-shaped formation of the glazing bar,
• (b) push fitting the generally U-shaped formation of the bracket over the U-shaped formation at the free end of the stem of the glazing bar of the mullion,
• (c) locating the self-tapping screw in the or at least one of the apertures in the web portion of the generally U-shaped formation of the bracket, and screw-threadably engaging the screw with the groove in the U-shaped formation of the glazing bar, and
• (d) connecting an item to the bracket.

Solar shading attached to curtain walling mullions by a method comprising the steps of:

• (a) selecting apparatus for attaching solar shading to curtain wall mullions of wall mullions of the kind herein defined, the apparatus comprising:
• a bracket having a generally U-shaped formation at one end for fitting over the generally U-shaped formation of the glazing bar of a mullion,
• a substantially planar portion which, when the bracket is fixed to the mullion, projects forwardly of the glazing bar and in use between two adjacent glazing units, and
• a seal locating formation projecting laterally of the substantially planar portion, the generally U-shaped formation comprising a web-portion and two parallel or substantially parallel side portions, the web portion having an aperture therein above and/or below the substantially planar portion for receiving a self-tapping screw which can, in use, extend through the aperture and engage with the groove in the U-shaped formation of the glazing bar,
• (b) push fitting the generally U-shaped formation of the bracket over the U-shaped formation at the free end of the stem of the glazing bar of the mullion,
• (c) locating the self-tapping screw in the or at least one of the apertures in the web portion of the generally U-shaped formation of the bracket, and screw-threadably engaging the screw with the groove in the U-shaped formation of the glazing bar, and
• (d) connecting an item to the bracket.
