Prestressed construction process for building high-rise building structure
The invention discloses a prestressed construction process for building a high-rise building structure. All steel wire ropes in prestressed tendons are dispersedly anchored through first anchor bearing plates and corresponding first anchorage devices, so that the problem that stress on the surrounding structure of the first anchor bearing plates is concentrated after tension releasing is avoided; all the first anchor bearing plates are arranged along the spherical surface, i.e. the bearing surfaces of all the first anchor bearing plates are supported by an imaginary sphere, so that the stress is more uniform, and the stability of the anchoring structure is facilitated; and second anchor bearing plates, cavity molds and templates are relatively fixed, so that holes, through which the prestressed tendons can penetrate, of the second anchor bearing plates, the cavity molds and the templates are not staggered, the prestressed tendons can be arranged to be perpendicular to the outer surfaces of the templates all the time, the process requirement is met, and accurate implementation of prestress of the high-rise building structure is guaranteed. The prestressed construction process has the advantages of simple steps, convenience in operation and good effect.
本发明公开了一种用于建筑高层建筑结构的预应力施工工艺，通过所述第一锚垫板及对应的所述第一锚具对预应力筋中所有所述钢丝绳进行分散锚固，避免了放张后对所述第一锚垫板周围结构应力集中的问题；所有所述第一锚垫板沿球面设置，即所有所述第一锚垫板的承力面被一个假想的球体顶住，受力更加均匀，利于锚固结构的稳定；通过将所述第二锚垫板、所述穴模和所述模板相对固定，使得所述第二锚垫板、所述穴模和所述模板用于穿过所述预应力筋的孔位不能发生错位，使得所述预应力筋能够一直垂直于所述模板外表面设置，满足工艺要求，确保高层建筑结构的预应力准确实施，该施工工艺步骤简单，操作方便，效果良好。
