Construction method of multilayer steel-concrete structure semi-top-down design

Abstract

The application discloses a kind of multilayer steel concrete structure semi-reverse construction design construction methods, it is related to building steel structure construction technical field.The method includes construction column lower foundation and hoists steel column, forms combined foundation to column foot by outer wrapping concrete reinforcement, hoists all floor steel beam column to form frame, preferentially lays roof layer to exempt from formwork steel bar truss floor slab to form temporary closed water surface, installs roof sliding hook system, utilizes the hoisting system to efficiently complete lower each floor floor construction under indoor environment, finally removes temporary facilities to complete main body.The application realizes that main structure is closed water, construction environment is fundamentally improved, measure cost is significantly saved and period is effectively shortened by semi-reverse process of roof first and lower part, in combination with overturning resistance design of outer wrapping combined column foundation, detachable sliding hook transportation system, with the outstanding advantages of high efficiency, low carbon and safety.
