Temporary pier elevation determination method for girder few-fulcrum erection method
The invention discloses a temporary pier elevation determination method for a girder few-fulcrum erection method, which comprises the following steps of: sequentially numbering each temporary pier as Nj along the girder erection direction, j = {1, 2, 3...}; according to the linear relation between the deflection of the maximum cantilever state before the main beam is erected to the temporary pier Nj and the height of a pad needing to be arranged on the temporary pier Ni when the main beam is just erected on the temporary pier Nj, the total height delta hi of the pad of the temporary pier Ni when the main beam is just erected on the temporary pier Nj is calculated, and i = {1, 2, 3...} and ilt; j; and the delta hi and the beam bottom elevation f0 manufactured at the temporary piers Ni according to the line shape of the main beam are overlapped, and the elevation Hi of each temporary pier Ni when the temporary piers Nj are arranged on the main beam is obtained. According to the method, a reserved height empirical value does not need to be used, the more accurate temporary pier elevation can be obtained, the construction efficiency and the construction precision of girder erection are improved, and smooth erection of the girder is ensured.
本发明公开了一种用于主梁少支点架设法的临时墩标高确定方法，包括：对各临时墩沿主梁架设方向依次编号为Nj，j＝{1,2,3…}；根据主梁架设至临时墩Nj前最大悬臂状态的挠度与主梁上临时墩Nj时需要在临时墩Ni设置的抄垫高度成线性关系，计算主梁刚好上临时墩Nj时临时墩Ni的抄垫总高度Δhi，i＝{1,2,3…}且i
