【Abstract】：Aiming atsetting andoptimizationdesignofredoorinthenarrow spaceofthecontactpassage，taking the actual project as an example，basedon.summing up the requirements of fire door setting，the relationship between fire door seting and special lining segment opening size，and the disadvantages of oblique fire door setting insmallspace of contact channel，it is proposed forthe first time thatunder the premise that the opening size of special lining segment and the headroom size in the contact channel are limited，the space of spacer spaceinsteel pipe segment is used to meet the needs of widening fire dooropenings in smallspace.Then reasonably set the fire door optimization scheme.
