5. A method for preparing the honeycomb hollow-out grid tubular double-steel-plate concrete composite shear wall of claim 1, wherein the method comprises the following steps: the method comprises the following steps:
the method comprises the following steps: blanking rectangular steel pipes of concrete filled steel pipe end columns (1) in a steel structure processing factory according to design requirements, processing and manufacturing honeycomb hollowed steel plates (2) and honeycomb hole tie steel plates (3) in the factory, and firmly welding the rectangular steel pipes of the left concrete filled steel pipe end column (1) and the right concrete filled steel pipe end column (1), the front honeycomb hollowed steel plate (2) and the rear honeycomb hole tie steel plates (3) by using holes of the honeycomb hollowed steel plates (2) to form a honeycomb hollowed grid tubular wallboard (A);
step two: conveying the honeycomb hollowed-out grid tubular wall board (A) to a construction site of a super high-rise building, hoisting the honeycomb hollowed-out grid tubular wall board (A) in place, welding and assembling a plurality of honeycomb hollowed-out grid tubular wall boards (A) to form an L-shaped shear wall, a T-shaped shear wall and a cross-shaped shear wall, installing a wall hole sealing counter-pulling small template (5) to cover holes of a honeycomb hollowed-out steel plate (2), and pouring in-pipe concrete (4) in a cavity of the honeycomb hollowed-out grid tubular wall board (A) to form a honeycomb hollowed-out grid tubular double-steel plate concrete combined shear wall system;
step three: placing the steel bar truss floor bearing plate in the hole of the honeycomb hollowed steel plate (2), binding a floor slab steel bar mesh, and pouring floor slab concrete to form a reinforced concrete floor slab (6);
step four: on the construction site of a super high-rise building, a plurality of floor structures are simultaneously and alternately operated for construction, a honeycomb hollowed-out type grid tubular wallboard (A) is hoisted and welded in place on the upper floor, a steel bar truss floor bearing plate is placed in a hole of a honeycomb hollowed-out steel plate (2) on the floor, a floor reinforcing mesh is bound, concrete (4) in a pipe is poured on the lower floor, and the floor concrete is poured, so that the super high-rise building structure can be quickly built until the roof of the building structure is sealed.
