Prefabricating large openings in concrete frames (002)
The facade of the Broadwalk House building stands out for having exploited to the maximum the potential of prefabricated concrete panels.
The speed on the execution of the building was decisive in the decision making. This requirement led to resort to prefabrication of both the structure and the enclosure.
Being a façade where the hollow dominates, the panels were designed as concrete frames that surround large windows. About two-thirds of the surface of the panel is glass. The use of the panels speeded up the process and facilitated the assembly thanks to a clever strategy: the blind small panel that covers the windowsill is a guide for the placement of the upper panel, while transmitting its weight to the slabs. A rod located on the edge of the windowsill panel guides the correct positioning of the top panel that simply attaches to the structure of the building to avoid leaning, supporting all its weight in the bottom panel.
