Support-free construction method and structure for high-altitude large-cantilever steel beam
The invention discloses a support-free construction method and structure for a high-altitude and large-cantilever steel beam. The construction method comprises the following steps that S1, a proper support-free structure is selected; s2, a stand column assembly of a support-free structure is arranged on the outer frame main steel beam; s3, the non-cantilever section steel beam and the stand column assembly are connected through a first pulling assembly of a supporting-free structure; s4, the large cantilever section steel beam and the stand column assembly are connected through a second pulling assembly of a supporting-free structure, and then the large cantilever section steel beam and the outer frame main steel beam are welded and fixed; s5, according to the steps S2 to S4, installation of adjacent large cantilever section steel beams is completed; then, secondary beams between the adjacent large cantilever section steel beams are installed; s6, according to the steps S2 to S5, installation of the remaining large cantilever section steel beams and secondary beams is completed; s7, after the whole structure is connected, unloading is conducted one by one, and the support-free structures are dismantled; the method is beneficial to improving the construction efficiency, reducing the construction cost and ensuring the construction safety.
本发明公开了一种高空且大悬挑钢梁的免支撑施工方法及结构，施工方法包括以下步骤：S1、选用合适的免支撑结构；S2、在外框架主钢梁上设置免支撑结构的立柱组件；S3、用免支撑结构的第一拉结组件，将非悬挑段钢梁与立柱组件连接起来；S4、再用免支撑结构的第二拉结组件，将大悬挑段钢梁和立柱组件连接起来，之后，将大悬挑段钢梁与外框架主钢梁焊接固定；S5、按照S2～S4步骤，完成相邻大悬挑段钢梁的安装；之后，再安装相邻大悬挑段钢梁之间的次梁；S6、按照S2～S5步骤，完成剩下的大悬挑段钢梁和次梁的安装；S7、整体结构连接完成后，逐一卸载，拆除免支撑结构；该方法有利于提高施工效率，降低施工成本，保证施工安全。
