Discussion on motivation control of the electricdriven fire roller shutter in Junyi Garden;

Problems arising in the auto-control process of the fire roller shutter are being discussed in this paper and measures in solving these problems are presented as well.

This paper probes into the linkage of the current auto-fire-alarming system with the fire equipment from aspects of the auto-spraying system, gas-extinguishing system, smoke prevention system, elevator; and fire-resisting rolling shutter, etc.

In these buildings, people used fire-resisting rolling shutter to replace the firewall as the partition facility to satisfy large space requirement.

In order to solve the problem of wasting water in cooling fire-resisting rolling shutter.

Based on the fire compartmentation principle,give a feasibility analysis and discusion,with a comparsion between the actual designing and regulatory should-be creteria of fire-proof roll screen designing regarding the Library of Songshan Lake divsion,also,seek a reasonable solution between practical technology and current regulation.

Study on main steel shaft design for fireproof rolling shutter door;

There are three kinds of fireproof door accommodated namely:the steel fireproof door,the fireproof and theftproof door and the composite steel fireproof rolling shutter door.
