近年来，随着高层建筑的大量兴建和施工速度的加快，相应地发展了大模板施工工艺。采用泵送混凝土进行大模板施工，稍加振捣就能保证混凝土的均匀性和密实性。在拆模后，大模板施工的混凝土表面平整光洁，能较好的避免蜂窝，麻面等弊端。同时，大模板施工能提高拆模速度，... In recent years, with the large-scale construction of high-rise buildings and the acceleration of construction speed, large formwork construction technology has been developed accordingly. The use of pumped concrete for large formwork construction and slight vibration can ensure the uniformity and compactness of the concrete. After the mold is removed, the concrete surface of the large formwork construction is smooth and smooth, which can better avoid the disadvantages of honeycombs and pockmarks. At the same time, large formwork construction can increase the speed of demolding,...
