The invention discloses a six-support lower bearing supporting type tower crane supporting system. The six-support lower bearing supporting type tower crane supporting system comprises a first horizontal supporting main beam, a second horizontal supporting main beam, a first horizontal oblique beam, a second horizontal oblique beam, a first horizontal connecting beam, a second horizontal connecting beam, a first horizontal oblique beam inclined strut, a second horizontal oblique beam inclined strut, a third horizontal oblique beam inclined strut and a fourth horizontal oblique beam inclined strut. For a supporting system with tower crane supports attached to main body structure columns, when a traditional supporting system containing three or four horizontal stress supports cannot be used due to the fact that the distance between the two columns is large, the supporting system adopts the two horizontal stress supports and four inclined supporting supports, the two horizontal stress supports at the ends of the first horizontal oblique beam and the second horizontal oblique beam are connected with a main body structure, and the problems that the distance between attachment points is large, and an occupied space is large are solved. Four lower inclined struts are adopted for supporting, a stable space structure system is formed, the stress of the single inclined strut is reduced, the counter force of the support is shared, and the reinforcing difficulty of the main body structure is reduced.
本发明公开了一种六支座下承支撑式塔吊支撑体系,包括:第一水平支撑主梁、第二水平支撑主梁、第一水平斜梁、第二水平斜梁、第一水平连系梁、第二水平连系梁、第一水平斜梁斜撑、第二水平斜梁斜撑、第三水平斜梁斜撑、第四水平斜梁斜撑。对于塔吊支座附着在主体结构柱上的支撑体系,由于两柱之间距离较大,无法使用传统含有三个或四个水平受力支座的支撑体系时,本发明支撑体系采用两个水平受力支座和四个斜撑支座,运用第一水平斜梁和第二水平斜梁端部两个水平受力支座与主体结构连接,解决附着点距离较大占用空间较大的问题。采用四根下斜撑支撑形式,形成稳定的空间结构体系,减小单根斜撑受力,分担支座反力,降低主体结构加固难度。
