无粘结预应力技术是解决超大面积楼盖温度应力的新技术,这样可使结构受拉区域预先受到压应力作用,而这种压应力将能抵消一部分或全部由使用荷载或温度所产生的拉应力,从而推迟裂缝出现的时间和减小裂缝的宽度,提高结构的刚度。
Unbonded prestressing technology is a new technology that solves the thermal stress of oversized floor coverings so that the structural tensioned area is pre-stressed by compressive forces that will counteract some or all of the stress caused by service loads or temperatures Tensile stress, thereby postponing the occurrence of cracks and reducing the width of cracks to improve the structural rigidity.
