The invention belongs to the technical field of building construction, particularly relates to a jacking and extending system and a tower crane dismantling method, and provides the following scheme aiming at the problems that in the prior art, standard knots are difficult to carry, and time and labor are wasted during installation and dismantling of the standard knots: the jacking and extending system comprises a tower crane main body and a jacking cross beam slidably arranged on the outer wall of the tower crane main body in a sleeving manner, the tower crane comprises a tower crane body, the tower crane body is formed by vertically stacking a plurality of standard knots, a plurality of three-rod supports are fixedly connected into the standard knots, and the connecting structures are arranged in the standard knots and used for fixedly connecting every two vertically-adjacent standard knots. According to the jacking device, the jacking cross beams are arranged on the standard knots, the two vertically adjacent standard knots are in butt joint, in addition, the limiting effect on the standard knots and the jacking cross beams can be achieved, the jacking cross beams are prevented from shaking during sliding, the standard knots can be moved easily through clamping of the U-shaped clamping buckle frames on the standard knots, and carrying can be completed without too much manpower.
本发明属于建筑施工技术领域,尤其是一种顶伸系统及塔吊拆除方法,针对现有技术中标准节搬运困难,标准节安装、拆卸费时费力的问题,现提出如下方案,其包括:塔吊主体以及滑动套设在塔吊主体外壁的顶升横梁,所述塔吊主体由多个标准节上下叠加形成,所述标准节内固定连接有多个三杆支架,连接结构,设置在标准节内,用于将上下相邻两个标准节进行固定连接,本发明中,通过滑动横梁、导向槽和顶块的配合不但能够方便对标准节的搬运,以及对上下相邻两个标准节进行对接,另外还能够对标准节和顶升横梁起到限位作用,防止顶升横梁在滑动时出现晃动,且在U型卡扣架对标准节的卡接能够轻松的对标准节进行移动,无需过多人工便可完成搬运。
