Construction method for integrally jacking and replacing new steel roof and old steel roof
The invention discloses a construction method for integrally jacking and replacing a new steel roof and an old steel roof. The construction method mainly comprises the following steps of integrally assembling the new steel roof on an assembling jig frame under the old steel roof; arranging an integral jacking system; jacking the new steel roof to the bottom of the old steel roof through the jacking system, and arranging profile steel brackets I; arranging a plurality of profile steel brackets II; removing the connection between the old steel roof and peripheral permanent structures; jacking the new steel roof and the old steel roof together, and enabling the new steel roof to be jacked to the designed elevation; fixing the new steel roof; and cutting and disassembling the old steel roof onan operation platform provided by the new steel roof. The construction method is slightly influenced by weather factors, the requirement for cranes is low, and an internal building structure is fullyprotected in the construction process; and besides, the new steel roof provides a safe operation platform for the dismantling work of the old steel roof, the safety problem of aloft work is solved, the dismantling difficulty of the old steel roof is reduced, a plurality of working surfaces can be constructed at the same time, and the construction efficiency is effectively improved.
本发明公开了一种新老钢屋盖整体顶升更换施工方法，主要包括如下步骤：在老钢屋盖正下方的拼装胎架上进行新钢屋盖整体拼装；设置整体顶升系统；利用顶升系统顶升新钢屋盖至老钢屋盖底部，设置型钢支托一；设置若干型钢支托二；去除老钢屋盖与外围永久结构的连接；新钢屋盖与老钢屋盖一起顶升，使新钢屋盖顶升至设计标高；固定新钢屋盖；在新钢屋盖提供的操作平台上对老钢屋盖进行切割解体。所述施工方法受天气因素影响较小，对起重机要求低，施工中内部建筑结构得以充分保护；而且，新钢屋盖为老钢屋盖的拆除工作提供了一个安全的操作平台，解决了高空作业的安全问题，降低了老钢屋盖拆除难度，可以使多个工作面同时施工，有效提高了施工效率。
