1. enhanced modular fire prevention extract duct, comprise extract duct, inside casing and pillar, it is characterized in that:

  • square frame shape section extract duct (1) relies on gluing, screw or nail catcher to connect to form by four blocks of glass magnesium plates, and the outer wall that the first party shaped as frame that is positioned at square frame shape section extract duct (1) strengthens inside casing (3) or second party shaped as frame enhancing inside casing (4) matches with the inwall of square frame shape section extract duct (1);

    Described first party shaped as frame strengthens the following thickness of the top thickness of (3) four side plates of inside casing greater than four side plates, four inwalls that the first party shaped as frame strengthens inside casing (3) constitute up-small and down-big square taper, and four right angles that the first party shaped as frame strengthens inside casing (3) all are provided with square corner post or triangle corner post;

    Described second party shaped as frame strengthens the following thickness of the top thickness of (4) four side plates of inside casing less than four side plates, four inwalls that the second party shaped as frame strengthens inside casing (4) constitute up big and down small square taper, and four right angles that the second party shaped as frame strengthens inside casing (4) all are provided with square corner post or triangle corner post;

    That the inwall on square frame shape section extract duct (1) top relies on is gluing, screw or nail catcher positioning and fixing first party shaped as frame strengthen inside casing (3), and that the inwall of square frame shape section extract duct (1) bottom relies on is gluing, screw or nail catcher positioning and fixing second party shaped as frame strengthen inside casing (4);

    Be provided with pillar (6) between four corresponding right angles of first party shaped as frame enhancing inside casing (3) and second party shaped as frame enhancing inside casing (4), pillar (6) both ends of the surface strengthen four corresponding right angles that inside casing (3) or second party shaped as frame strengthen inside casing (4) with the first party shaped as frame that reclines mutually respectively and rely on gluing, screw or nail catcher fixedly connected, and two right angle facades of pillar (6) rely on gluing, screw or nail catcher to fixedly connected with square frame shape section extract duct (1) inwall that reclines mutually respectively;

    The even Distribution and localization of the outer wall fastening alkali proof fiber grid cloth cover (2) of square frame shape section extract duct (1), the top, a side of square frame shape section extract duct (1) is avoided alkali proof fiber grid cloth cover (2) and first party shaped as frame enhancing inside casing (3) and is provided with air inlet port (5).
