Construction Study On Large Span Structure Of Double-lager Grids And Flat Slab System

In progress analysing and studying to the structure system of the steel network , has been in progress analysing contrasting to two kinds of different steel network structure construction plans, and the measure that has put forward the more excellent steel network construction plan and ensures the construction quality .By way of experiment and constructions with two steel network engineerings, has been in progress analyzing and studying to steel network efficacy by different types putting up and boundary condition and the aspects have carried on analysis research to the stress influence of distribution etc during different types are supported to steel network, and from steel network has been in progress the analysis with steel quota and economy . Combining the items of the construction : the steel networks of the engineering at Hebei University Gym Activity Center , and the engineering at the Hebei Economics University student dining room , the networks have been making , installing and reach in anticorrosive and the fire prevention etc aspects ,the follows research analysis gone forward the line , and detailedly expound steel network pledges construction quality and technical measure. The research for the application and construction of large span concrete structure of hollow plate prestressed with unbonded tendons has been in progress to the fooding and drunking engineer of the 54th Research Institute of Electronics Information Ministry of China ,and conclude a series of more excellent construction technologies with accelerating construction progress and improving structure efficacy.
