The invention relates to a construction method for preventing deformation of a full-width superstructure, which comprises the following steps: step 1, in a sectional assembly stage, after assembly and positioning are completed, arranging an auxiliary support between a lower opening of a longitudinal bulkhead without a solid rib plate and a lower opening of a peripheral wall of the superstructure; step 2, carrying out segmented assembly welding, and releasing the support of the auxiliary support after the assembly welding is completed; 3, after the stress of the superstructure is released, the construction precision of the superstructure is measured and corrected; 4, resetting and supporting the auxiliary support; and 5, the superstructure is hoisted, and the auxiliary supports are dismantled before hoisting and hook loosening. According to the method, the stress is released by dismounting the auxiliary support, so that the situation that the assembly stress cannot be released due to the existence of the auxiliary support is avoided, the influence of the existence of the auxiliary support on the construction precision measurement of the upper construction section is further avoided, the upper construction section is in a natural state, and the accuracy of precision measurement correction is improved.

    本发明涉及一种全宽型上层建筑防止变形的施工方法,包括:步骤1、在分段装配阶段,装配定位完成后,在上层建筑未设置实肋板的纵向舱壁下口和外围壁的下口之间设置辅助支撑;步骤2、进行分段的装配焊接,待装配焊接完成后,解除辅助支撑的支撑;步骤3、待上层建筑应力释放完成后,对上层建筑进行建造精度测量及修正;步骤4、辅助支撑复位支撑;步骤5、对上层建筑进行吊装,吊装松钩前拆除辅助支撑。本发明通过拆除辅助支撑进行应力释放,避免由于辅助支撑的存在导致装配应力无法释放,进而避免由于辅助支撑的存在对上建分段的建造精度测量产生影响,使得上建分段处于自然状态下,提升精度测量修正的准确性。
