Above-ground wildfire shelter with steel a-frame structure

Abstract

An above-ground, A-frame wildfire shelter designed to withstand extreme wildfire conditions is disclosed. The structure is fireproof and is fabricated entirely from non-combustible metals to ensure durability under severe thermal exposure. The A-frame roof configuration offers significant advantages, including reduced gravitational load and inherent angular bracing, as the opposing rafters support one another. Roofing panels are mounted directly to the rafters for structural integrity. To address prolonged exposure to temperatures approaching 1,000° C., the design incorporates passive cooling through hollow, rectangular rafters. These rafters facilitate airflow, drawing cooler air from near ground level and discharging heated air above the roofline. Additionally, the A-frame geometry can be scaled to accommodate an integrated off-grid electrical system, enabling geothermal cooling to mitigate soak-back heat within the shelter.
