Abstract ：As a result of the global urbanization's day-by-day expansion, the high-rise building increases day by day. Simultaneously domestic does not have the practical popular family tall building fire escape apparatus temporarily. But in the market exists the tall building fire escapes the installment existence price to be expensive, operation complex or flaws and so on installment difficulty. But this product has the structure regarding other same type product to be simple, easy to make, easy to realize the tendency from merits and so on control rate of descent. The design content includes: The tall building fire escapes the installment structural design, the steel wire recovery system's design. The design mainly divides into four parts: The first part is an introduction, the second part is the tall building fire escapes the installment present situation and the trend of development, the third part is design proposal sketch, the fourth part is designs the research the content. Finally also includes the concluding remark, the acknowledgment and the reference
