Abstract

A honeycomb hollowed-out type grating tubular double-steel-plate concrete composite shear wall comprises steel pipe concrete end columns, honeycomb hollowed-out steel plates and honeycomb hole tie steel plates, the honeycomb hollowed-out steel plates are thin steel plates provided with holes arranged in an orthogonal array mode, and the two honeycomb hollowed-out steel plates are arranged in front of and behind the left steel pipe concrete end column and the right steel pipe concrete end column. A plurality of honeycomb hole tie steel plates are arranged between the two honeycomb hollowed-out steel plates, the honeycomb hollowed-out steel plates, the honeycomb hole tie steel plates and the honeycomb hollowed-out steel plates are welded to form honeycomb hollowed-out grating tubular wallboards, the wallboards are welded and spliced to form L-shaped, T-shaped and cross-shaped shear walls, concrete is poured into the pipes, and the honeycomb hollowed-out grating tubular double-steel-plate concrete composite shear wall system is formed. The honeycomb hollow-out steel plate is adopted, a large amount of steel is saved, the hoisting weight is reduced, the problem that welding construction of an internal tie steel plate is difficult is solved, the steel bar truss floor bearing plate is placed in a hole of the honeycomb hollow-out steel plate, the problem of bearing connection of a reinforced concrete floor is solved, and the honeycomb hollow-out grating tubular wallboard is also used as a vertical temporary support. A plurality of floors are constructed at the same time, and a super high-rise building can be rapidly built.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a combined shear wall structure, in particular to a honeycomb hollowed-out grid tubular double steel plate concrete combined shear wall and a preparation method thereof. Background technique [0002] As the crystallization of modern construction technology, super high-rise buildings enhance the image of cities and countries. As the height of the building increases, the horizontal seismic action will increase significantly, and a lateral-force shear wall structural system must be installed to resist strong earthquakes. [0003] The lateral stiffness and seismic ductility of the shear wall structure are very critical factors in the structural design of super high-rise buildings. The concrete shear wall has the advantage of high lateral stiffness, but its seismic ductility is poor; the pure steel plate shear wall has good seismic ductility. advantages, but its lateral rigidity is low...

AI Technical Summary

Problems solved by technology

[0004] At present, some problems have been encountered in the popularization and application of double steel plate concrete composite shear walls in super high-rise buildings, and its structural construction technology is not mature enough

The traditional double-steel-steel-concrete composite shear wall requires a large amount of steel, high cost, poor economic index, and heavy hoisting weight; in order to avoid the buckling of the outer steel plate, the traditional double-steel-concrete composite shear wall needs It is necessary to install internal tie steel plates. However, due to the thinner wall of the shear wall and the narrow internal space, the welding construction of the tie steel plates is very difficult. Therefore, a large number of studs have to be welded inside the steel plates, which is laborious; It is difficult to connect the double steel plate concrete composite shear wall structure and the reinforced concrete floor structure. The outer side of the double steel plate concrete composite shear wall adopts a whole steel plate. At the floor, the reinforced steel bars of the reinforced concrete floor structure cannot penetrate the double steel plate Concrete composite shear walls lead to difficulties in the anchorage construction of reinforced concrete floor structures
