The reinforced concrete coupled shear wall and the hole connecting beam in the wall type frame are weak parts of the shear wall structure, and the rigidity, the strength and the deformability of the reinforced concrete coupled shear wall have great influence on the seismic performance of the shear wall.
From a structural safety perspective, since the wall limbs bear horizontal and vertical loads, which are the main components of the structure, the destruction of which often results in the collapse of the superstructure without support, resulting in the overall destruction of the structure, which can result in significant casualties and property damage. From the viewpoint of structural restoration, since the wall bears the huge pressure generated by the dead weight of the superstructure, the damage of the wall is usually difficult to restore or the restoration cost is huge, so that even if the structure is not damaged, the repair work is difficult or the restoration cost is increased. From the perspective of structural seismic resistance and energy consumption, because the shear wall is the main component of building bearing and lateral force resistance, the normal use and safety of the structure are seriously influenced by the yield and even damage of the shear wall.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments disclosed below.
Referring first to fig. 1 to 5, an embodiment of the present invention provides a coupled shear wall structure that can be repaired after an earthquake of a coupling beam floor slab, and the coupled shear wall structure mainly comprises a shear wall main body 1, a coupling beam and a floor slab. The shear wall body 1 can be a steel pipe concrete combined shear wall, and mainly comprises a plurality of vertical steel pipes connected side by side and concrete filled in and out of the steel pipes, and reinforcing steel bar reinforcing structures such as stirrups can be arranged outside the steel pipes.
The connecting beam is a combined connecting beam and consists of a connecting beam rigid section 21 and a connecting beam replaceable section 22. One side of the connecting beam rigid section 21 is fixedly connected with the shear wall main body 1 on the corresponding side, and when the shear wall main body 1 is a steel pipe concrete combined shear wall, one side of the connecting beam rigid section 21 is fixed with a steel pipe (the outermost steel pipe) in the steel pipe concrete combined shear wall. This even roof beam rigidity section 21 can adopt T shaped steel, includes a curb plate and a medium plate that sets up along curb plate perpendicular bisector, and this curb plate is used for connecting even removable section 22 of roof beam, and one side and the steel pipe welded fastening of keeping away from the curb plate of this medium plate.
The rigidity of the connecting beam rigid section 21 is higher, the rigidity of the connecting beam replaceable section 22 is lower, and the connecting beam replaceable section 22 is detachably connected between the two connecting beam rigid sections 21 on two sides through the bolt 222, so that the connecting beam replaceable section 22 yields before the connecting beam rigid section 21 in the earthquake process, and can be detached and replaced through the bolt 222 connection after the earthquake. The removable section 22 of this link beam can adopt the I-steel, including both sides pterygoid lamina and the middle web that sets up along the perpendicular bisector of both sides pterygoid lamina, and both sides pterygoid lamina is connected with the curb plate of both sides T shaped steel through bolt 222 respectively, corresponds to seting up the hole that supplies bolt 222 to wear to establish on pterygoid lamina and the curb plate, and the cooperation has the nut on the bolt 222. The middle plate of the T-shaped steel and the web plate of the I-shaped steel are positioned on the same vertical surface. When the connecting device is connected, the bolt 222 sequentially penetrates through the side plate and the wing plate and is screwed and fixed by the nut after penetrating out of the wing plate, so that the nut can be conveniently unscrewed on one side of the connecting beam replaceable section 22 afterwards, and the connecting beam replaceable section 22 is taken down from the connecting beam rigid section 21 for replacement.
Furthermore, the top elevation of the wing plates at the two sides of the connecting beam replaceable section 22 is higher than that of the middle web plate thereof, so that a rectangular installation space is formed; the top of the web is provided with a horizontal connecting plate on which a split bolt 221 is arranged.
The floor slab part is composed of a combined type coupling beam floor slab and a peripheral common floor slab 33, the combined type coupling beam floor slab comprises a replaceable floor slab 31 connected to the coupling beam replaceable section 22 and a repairable floor slab 32 constructed around the shear wall main body 1, a gap exists between the repairable floor slab 32 and the replaceable floor slab 31, the common floor slab 33 is located on the periphery of the repairable floor slab 32 and is far away from the shear wall main body 1, specifically, the longer the distance is determined according to the anti-seismic performance, the better the anti-seismic performance is, but the larger the consumption of the repairable floor slab 32 is, otherwise, the closer the distance is, the lower the anti-seismic performance is, but the consumption of the repairable floor slab 32 can be saved, but no matter how far the distance is, the repairable floor slab 32 is arranged on the periphery of the shear wall main body 1, and even the common floor slab 33 is arranged on the periphery of the repairable floor slab 32.
Preferably, the repairable floor 32 is a cast-in-place ECC concrete floor, ECC (ECC) concrete, that is, ductile high-performance concrete, which is high-toughness concrete, has strong deformability, does not generate through cracks after earthquake, only generates a large amount of micro cracks, and can be repaired by spraying ECC concrete. The ordinary floor slab 33 is an ordinary cast-in-place concrete floor slab.
The repairable floor 32 is poured on the coupling beam rigid section 21 at the periphery of the shear wall main body 1, and in order to enhance the concrete combining capacity, a stud 211 is arranged at the top of the coupling beam rigid section 21.

By adopting the coupling shear wall structure with the repairable coupling beam floor slab after the earthquake, under the action of the earthquake, the detachable floor slab is deformed and damaged only along with the replaceable section of the coupling beam because a gap exists between the detachable floor slab and the repairable floor slab. Meanwhile, the constraint on the ECC floor is released due to the existence of the gaps, and the deformation of the ECC floor on the upper part of the connecting beam is reduced. Due to the ultra-strong deformability of the ECC, within the range of 2% of the interlayer displacement angle, the ECC concrete floor can not be irreparably damaged, and can be repaired after an earthquake. And the common floor slab at the distance is not damaged due to small deformation. Therefore, after earthquake, the ECC floor can be repaired only by replacing the detachable floor and spraying ECC concrete to repair the ECC floor.
The replaceable coupled shear wall structure of the coupling beam floor slab after earthquake is suitable for being applied to earthquake-resistant areas, can reduce damage of the earthquake to buildings, and shortens the repairing time of the buildings.
