Theoretical Analysis And Applied Research On Fabricated Tower Crane Base Of Steel Cross-beam

Fabricated steel tower crane foundation makes use of high-strength bolt to assemble and connect into a whole with the help of steel not reinforced concrete structures. Compared with the in-situ reinforced concrete foundation, it can aovid the impact from climatic conditions, shorten the construction period. Moreover, steel components can be reused to reduce cost. At the same time, it's convenient to install and disassemble and beneficial to envrioment. Therefore, this new type of fabricated steel tower crane foundation is a new technology that possesses bright market prospects, great vale of research and socioeconomic benefits.Based on the summary of the tower crane foundation at home and abroad, this paper conductes a systemic dissertation on the key issues of fabricated steel tower crane foundation, including characteristics, scope, basic principles and key points in construction,etc.This paper is based on existing tower crane research, designing a new type of fabricated steel tower crane foundation through theoretical research, design calculation, structural testing to solve the problem concerning dimension, structure, piling capacity of the steel tower crane base cross beam, and connectivity of support pillar,etc. It provides a theoretical basis and related design formulas for engineering applications.Furthermore, it is gradually spread for application and accelerates technological innovation of Construction.At the end of the paper, it draw some conclusions and gave recommendations on the basis of research and analysis, which may help to develop and improve fabricated tower crane foundation to a certain degree.
