*门零售

锅炉房、变压器室等与其他部位之间应采用耐火极限不**的*隔墙和的不燃性楼板分隔。在隔墙和楼板上不应开设洞口，确需在隔墙上设置门、窗时，应采用***门、窗。

疏散走道在*分区处应设置常开***门。

剧场、电影院、礼堂确需设置在其他民用建筑内时应采用耐火极限不**的*隔墙和***门与其他区域分隔。

要保证*门的性能就要有正确的保护措施，在搬运的时候应该先垫起，再进行搬运，放的时候要注意垫平并排放整齐。门扇安装完成以后再检查一下，看看保护膜有没有损坏，门面上有没有污渍，发现问题要尽快解决。组装好的门面一定要放好，把门扇锁起来，避免被碰着磕着。在后的时候要在门的外面包上保护膜，搬运的时候千万不能把保护膜弄坏。
