按层数多寡而言,国内建筑可试作如下区分:2～3层为低层建筑,4～7层为多层建筑;9～11层为中高层建筑;13～16层为高层建筑;18层以上为超高层建筑。近十余年来,数量可观的高层建筑已在我国一些大城市里拔地而起,其比重在某些大城市里有继续增长的趋势。本文综合介绍钢筋混凝土结构高层及超高层建筑施工用的国产及进口自升塔式超重机,详细列举其型号规格及技术性能,供读者在组织施工时参考,并对使用中的几个主要问题提出一些看法。
According to the number of floors, domestic buildings can be tried to distinguish between: 2 to 3 floors for low-rise buildings, 4 to 7 floors for multi-storey buildings; 9 to 11 floors for high-rise buildings; 13 to 16 floors for high-rise buildings; 18 Above the floors are super high-rise buildings. In the past decade or so, a considerable number of high-rise buildings have risen in some of China’s major cities, and their proportion has continued to increase in some large cities. This article comprehensively introduces domestic and imported self-elevating tower type super heavy machines used in the construction of high-rise and super high-rise buildings for reinforced concrete structures, enumerates their model specifications and technical performance in detail, provides readers with reference during the organization of construction, and discusses several major issues in use. Make some comments.
