C. supporting the precast concrete inter-window wall by using diagonal braces;
D. pouring floor flanges on the structural steel beams to enable the precast concrete inter-window wall, the concrete floor and the structural steel beams to be connected with each other;
E. removing bottom dies and diagonal braces of the floor flanging after the floor flanging is hardened;
F. and an outer aluminum plate covering line, heat preservation rock wool, a fireproof gypsum board and an inner window board are arranged in the precast concrete inter-window wall.
Further, the surface of the concrete floor needs to be subjected to galling treatment.
Furthermore, the precast reinforcing steel bars of the precast concrete window partition wall are embedded into the flanging of the floor slab and are tightly combined with the flanging of the floor slab.
Furthermore, an external line interface, a window frame interface, a heat preservation rock wool interface and a window board interface are arranged on the outer surface of the precast concrete window wall, and the interfaces are sequentially used for installing an external line, a window frame, heat preservation rock wool and an inner window board.
Further, the wall between the precast concrete windows is internally provided with a sleeve for temporary supporting a stay bar and a sleeve for hoisting, the sleeve for temporary supporting the stay bar is used for installing an inclined stay bar in a matched mode, and the sleeve for hoisting is used for hoisting the wall between the precast concrete windows in a matched mode by a crane.
The invention has the beneficial effects that:
this structure has combined the advantage of prefabricated wallboard and cast-in-place wall between window, through the construction process of reserving reinforcing bar and floor turn-ups in inboard and pouring, changes the point load of traditional link plate into the line load, uses the structure arrangement of reinforcement that leads to the length to bear the moment of flexure that the part produced of encorbelmenting to make the wall body more firm.
