日本长谷工公司开发了可用于建造超高层大楼的新型钢筋混凝土技术,并且已经实际应用。新的制造程序是把钢筋扳成 X 形,交叉扎结,做成结实的柱状构造,周围围上增强钢筋后灌浇混凝土。钢筋混凝土构造比钢骨架结构造价便宜,但是由于强度问题,高层和超高层大厦不能采用钢筋混凝土结构。如果采用这项 X 形结构钢筋新技术,强度能够提
Hasegawa Corporation of Japan has developed a new type of reinforced concrete technology that can be used to build super high-rise buildings, and it has been put into practical use. The new manufacturing process is to pull the rebar into an X-shape, cross-knot, and make a strong columnar structure, surrounded by reinforced concrete and then poured concrete. The reinforced concrete structure is cheaper than the steel skeleton structure, but due to strength problems, high-rise and super-high-rise buildings cannot use reinforced concrete structures. If this new technology of X-shaped structural reinforcement is used, the strength can be improved.
