<p>A curtain wall comprises a framework of elongate main frame members defining cells in which infill panels are clamped by auxiliary frame members secured to the front of the framework. The panels are sealed in the cells by gaskets on the frame members. To prevent the weight of unclamped panels from distorting the auxiliary members and their securing screws, they rest on support elements projecting forwardly from slots in the transverse main frame members at the bottoms of the cells. The elements may relieve the auxiliary members entirely, or may rest on them when they are secured. Alternatively the panels may rest on the auxiliary members which transmit their weight to the support elements. The support elements and/or further locating elements can act to align the main and auxiliary members and guide the screws during construction.</p> |
