过去铁路施工用房都用临时房屋和帐篷。临时房屋一般需要大量木材,不但费工、修建工期长,而且在迁移时还要报废大批材料。帐篷虽然能灵活搬运,然而造价也高,使用寿命短,需要消耗大量的棉布和羊毛。为了多快好省地解决施工用房问题,我们进行了活动房屋设计。 一、我们设计了两种活动房屋。一是全装配的;二是只供应拆装式骨架,围护结构留待施工时就地取材加以解决。 活动房屋设计,需要特别注意运输和拆装的问题。构件类型和零件应尽量减少,以便利互换和简化安装手续,同时要尽量减小运 In the past, railway construction houses used temporary houses and tents. Temporary housing generally requires a large amount of wood, which not only requires labor and construction, but also requires scrapping of large quantities of materials during the relocation. Although the tents can be handled flexibly, the cost is high and the service life is short, requiring the consumption of a large amount of cotton cloth and wool. In order to solve the problem of construction houses more quickly and efficiently, we designed a mobile home. First, we designed two types of mobile homes. First, it is fully assembled; second, it only supplies dismantled skeletons, and the retaining structure is left to be used when the construction is completed. Mobile home design requires special attention to transportation and disassembly issues. Component types and parts should be minimized to facilitate interchange and simplify installation procedures while minimizing shipments
