超高层全现浇混凝土结构全高垂直度控制技术

Control technology of full-hight verticality of super-tall cast-in-situ concrete structure

根据现场实际情况,建立了高精度的测量控制网,将基准点引测到施工作业面,垂直度采用内外校核控制法,使主楼的各大角和电梯井道垂直度得到了有效和精确控制,从而使整个钢筋混凝土结构的最终全高垂直度的测量精度高于设计和规范要求。

According to the site actual situation, this paper established high accuracy measuring control nets, lead the datum mark to construction operation, vertical degree used inside and outside check method, made effective and precise control to each big angle and lift well vertical of the main building, so that made the measurement accuracy of finally full-hight verticality of entire reinforced concrete was higher than the requirement of design and specification.
