Abstract: A sloped wall structure is formed from a plurality of rafters arranged in spaced, parallel inclined attitude extending from a lower support surface upwardly to a higher support surface. Anchor clips are positioned at the lower end of each rafter and pivotally connect each rafter to the lower support surface. Similar anchor clips are optionally connected to the upper ends of each rafter and are also pivotally connected to the upper support surface. A baffle plate extends laterally across the wall structure and covers the lower ends of each rafter structure and supports the glass panes or other infill material at the lower edge of the wall structure.
