Technical Field
The invention relates to the technical field of assembled buildings, in particular to an assembled close-packed steel tube steel plate concrete shear wall for reversible construction.
Background
The reverse construction method of the high-rise building is an important construction method for solving the problem of land resource shortage of high-rise building in dense cities, and the method can be used for performing upper structure construction firstly and then (or synchronously) performing lower basement construction, so that more time is saved for the overall completion time of projects. In the implementation of the reverse construction method high-rise building, pile foundations are firstly constructed on the ground, and steel pipe columns of underground parts are hoisted to serve as vertical supports, so that after the underground soil discharge and the bottom plate are completed, reinforced concrete shear walls of the basement parts are positively constructed. In the traditional reverse working process of the basement, two major problems exist, namely when the number of layers of the upper structure is large, for example, when the number of layers of the upper structure is larger than 15, the reverse working process is poor in lateral resistance because the underground only has steel pipe columns as supports, and before the forward working shear wall of the basement is unfinished, the number of layers of the upper structure is limited, too many floors are not suitable to be built, and the overall finishing progress is slow to a certain extent; and secondly, the basement reinforced concrete wall is positively constructed in the later stage, the connection structure with the steel pipe column is complex, the underground operation is difficult, the implementation construction period is long, and the construction period is often a key node for limiting the whole construction period. Therefore, the shear wall member with better lateral force resistance and adaptability to reverse construction is sought to have great engineering significance.
In super high-rise buildings, as the building height is continuously increased, the cross section size of the reinforced concrete shear wall is gradually increased, so that the effective use area of the building is reduced, the self weight of the structure is increased, and the structural earthquake resistance and foundation are also adversely affected. The shear wall structure with high bearing capacity, ductility and construction efficiency has great significance.
In addition, horizontal effects on a port steel pile wharf, ship collision, sea waves, earthquakes and the like are often solved by applying inclined piles, but the inclined piles are difficult to apply and have long construction period, and meanwhile, the horizontal effects caused by the earthquakes are sometimes not well solved for the inclined piles in a high-intensity area. Therefore, the shear wall with good lateral force resistance, which is constructed in a reversible way, has good engineering significance.
Therefore, aiming at the wide application field, the assembled close-packed steel tube steel plate concrete shear wall capable of reversible construction is very necessary, and has great engineering significance.
