Tube-frame-supporting type hydraulic climbing integral steel platform formwork truss layer construction method

The invention provides a tube-frame-supporting type hydraulic climbing integral steel platform formwork truss layer construction method. A tube-frame-supporting type hydraulic climbing integral steel platform formwork comprises a steel platform system and a tube frame supporting system. The steel platform system is located on the upper portion of the tube frame supporting system and the upper side of a core tube construction floor. The steel platform system comprises a plurality of steel platform units and connecting beams, the steel platform units are connected into the integral steel platform, and steel deck plates are further arranged on the integral steel platform to form a construction platform. The construction method includes: demounting all the steel deck plates and the connecting beams interfered with the truss layer step by step; lifting up all assemblies of the truss layer from a cavity into core tubes step by step; after lifting, restoring part of the steel deck plates and connecting beams which are demounted in the above step to mounting, and connecting all the assemblies, lifted in place, of the truss layer and fixedly connecting the assemblies of the truss layer with shear walls of the core tubes to form the truss layer finally. By the application of the construction method, construction safety is effectively guaranteed, and construction circle is shortened.
