Curtain wall system with anti-rolling shear block

摘要

A curtain wall has a plurality of hollow, extruded vertical and horizontal members. The members have a pair of spaced retainer walls which engage a shear block with a pair of tabs that twist locks onto the retainer walls before fastening the block to the member. A second member slips over the block and is fastened by screws. The abutment of the tabs limits rotation of the block and attached member, providing support for a glazing panel attached to the members. The members have longitudinal recesses accommodating wiring that may be covered with a cover. A bracket interacting with the retainer walls like a shear block may also be used.

主权项

1. A structure, comprising:
a first member having a portion with a C-shaped cross-sectional shape and a pair of retainer walls, a first of the pair of retainer walls attached at a first end of the C-shaped portion and extending at an angle relative thereto, a second of the pair of retainer walls attached at a second end of the C-shaped portion and extending at an angle relative thereto, the pair of retainer walls extending in a direction toward one another; a shear block with a base portion having a pair of tabs extending therefrom in opposite directions, the tabs separated from a remainder of the base portion by reliefs, a connector portion extending from the base portion distal to the pair of tabs in a direction perpendicular to the tabs, each relief accommodating a corresponding retainer wall of the pair of retainer walls, capturing the corresponding retainer wall between the tab and the remainder of the base portion with the tabs extending in a direction parallel to an intermediate portion of the C-shaped portion between the first end and the second end thereof and positioned between the intermediate portion and the retainer wall, coupling the shear block to the first member; a second member having a hollow therein, the connector portion of the shear block matingly received in the hollow.
