| With the vigorous development of China’s construction industry, the increasing scale construction projects, particularly steel construction also By the people’s attention, steel installation technology matures, the country has built a large number of technically complex infrastructure, the Olympic project, large-scale public works and high-rise steel structure works, significantly improved our overall national strength and improve the substance of the people and cultural life of urban and rural areas has been significantly improved, reflecting the domestic steel engineering installation technical level to start a new situation. Because space is relatively large span steel structure, diversity, structural complexity of installation and construction techniques put forward higher requirements, must be carefully analyzed and compared various construction programs, according to engineering practice, considering various factors, choose to meet the requirements of the program. Thesis project examples for the installation of steel structure technology research, has good application value.Paper summarizes the construction method of steel structure hoisting, and expounds the slitting machine(block) installation, high bulk, high slip method, integrally jack-up method and integral lifting method and integral lifting method, net shell structure "fold expansion" integral lifting method of steel structure construction methods, such as the applicable conditions of these methods are put forward. Thesis combines with shenzhen podium steel truss steel structure engineering of a building as an example, from the podium of the general situation and the engineering characteristics of the steel truss, steel structure construction layout principles, the construction division, general layout and so on has carried on the detailed introduction;On the podium steel truss hoisting scheme selection, mechanical layout, the installation of the steel truss, the installation of skirt building steel column, steel column hoisting process, steel column lifting point set and temporary connection, the installation of the steel process and installation of steel beam and support jig system installation and removal, etc are analyzed and summarized, summarizes the installation technology of steel truss structure process; Using the finite element software SAP2000 and rapid Morgain structure design software key support in the process of steel truss hoisting jig design, support bracket in unloading process and the stress analysis of bearing capacity of concrete beam and then selected the meet the requirements of the engineering construction hoisting plan; Last to skirt welded steel truss structure construction process and security has carried on the detailed analysis, this paper make the welding quality in construction process of engineering guarantee.Through this project of steel structure engineering construction hoisting technology research, helps to deepen understanding of steel structure project construction lifting technology, but also for the future this kind of steel structure engineering construction is of certain reference significance. |
