高层建筑钢结构施工方法的变革,使楼板工程的做法发生变化,其主要意义在于促进施工工序安排合理化,其施工速度是钢结构吊装以后大量后继工程能否迅速展并的关键。楼板工程有压型钢板复合楼板、预制楼板、叠合楼板和普通现浇楼板等数种。 1.复合楼板在钢结构高层办公楼工程中,压型钢板复合楼板是采用最多的一种,原因是这种楼板系统(包括吊顶)特别有利于复杂的各种管线系统的铺设;在施工速度、简易程度、安全性和综合效果上都优于其他系统。其特点是:
The transformation of construction methods for high-rise building steel structures has changed the practice of floor slab construction. Its main significance is to promote the rationalization of construction process arrangements. The construction speed is the key to the rapid development of a large number of subsequent projects after steel structures are hoisted. There are several types of floor slabs, including pressed steel composite floor slabs, prefabricated floor slabs, superposed floor slabs, and cast-in-place floor slabs. 1. Composite floor slabs In the high-rise steel office building project, the pressure-laminated steel composite floor slab is one of the most used because the floor slab system (including suspended ceilings) is particularly advantageous for the laying of complex pipeline systems; It is superior to other systems in terms of simplicity, safety, and overall effectiveness. Its characteristics are:
