FRONT ELEVATION OR GLASS ROOF IN FIRE-PROOF VARIANT OF IMPLEMENTATION

摘要

construction industry. SUBSTANCE: front elevation or glass roof includes supporting structure made of sections of posts and cross-bars in which sections of posts and cross-bars are limited by field of frame fitted with fireproof glazing. Sections of posts and cross-bars should be manufactured of aluminum to form closed structural systems subject to joint treatment for use in fire-proof structures. Sections of posts and cross-bars have shaft shape carrying static loads which is embraced by U-shaped hollow chamber in area of its outer walls to take formed articles produced from hydrophilic adsorbent with high water content suppressing heating. Connection lintels which secure insufficient heat flow from outer wall of hollow chamber to section of shaft shape are provided between outer U-shaped wall of hollow chamber and shaft shape. EFFECT: crystallized water is released when hydrophilic adsorbent is activated by rise of temperature and is used to cool metal structures. 19 cl, 12 dwg
