Cast-in-place strip connections have the following significant disadvantages: the upper wall body is difficult to fix in the construction process, and 100 percent of the upper wall body is overlapped with the same section during connection; the concrete on the top surface of the cast-in-place belt is difficult to pour compactly. The application of sleeve grouting connection and preformed hole slurry anchor lapping is relatively wide, but the defects that the sleeve and the preformed hole are thick and the thickness of a protective layer is too small exist. In addition, the former has higher requirements on grouting materials, and the common fair-faced concrete in engineering is difficult to meet the requirements; if a large number of jacks are reserved in a wall body which is not too thick, the construction difficulty is high, and the holes are easy to damage in the transportation process, so that the connection performance of the components is influenced.
The dry connection mainly comprises bolt connection, key slot connection and the like, and is not widely applied at present. The pure bolt connecting bolt is easy to loosen and fall off under dynamic load, and the durability and reliability of the pure bolt connecting bolt are difficult to reach the standard. The key groove has good connection performance, but is mainly used in a large assembly plate structure.
In addition, the assembled double-steel-plate shear wall is commonly used in high-rise and super high-rise structures, and the vertical connection of the assembled double-steel-plate shear wall needs higher shear resistance than that of the common assembled concrete shear wall.

The invention is suitable for the vertical connection of the double-steel-plate concrete shear wall, particularly can be applied to the vertical connection of the double-steel-plate concrete shear wall with the damping interlayer, and further can be applied to the vertical connection of the double-steel-plate concrete shear wall with the damping interlayer of the outer concrete layer.
As shown in fig. 6-7, the double-steel-plate concrete shear wall with the damping interlayer of the outer wrapping concrete layer comprises a concrete core layer, a steel plate layer, the damping interlayer and an outer wrapping concrete layer which are sequentially arranged from inside to outside, wherein two sides of the steel plate layer are respectively connected with a steel tube concrete bundle, a concrete core is poured between the steel plate layer and the steel tube concrete bundle, and the double-steel-plate composite shear wall with the damping interlayer embedded with the outer wrapping pressure-bearing non-tensioned concrete further comprises a top plate and a bottom plate which are respectively connected to the top and the bottom of the wall body.
The steel plate layer comprises two parallel steel plates. The damping interlayer comprises two parallel damping interlayers, and the damping interlayer is located between the steel plate layer and the outer concrete coating layer. The outer concrete layer comprises two parallel concrete layers which are respectively wrapped outside the two damping interlayers.
The double-steel-plate combined shear wall with the externally-wrapped pressure-bearing non-tensile concrete embedded damping interlayer is formed by connecting constraint pull rod assemblies.
The outer concrete layer comprises a plurality of outer reinforced concrete layer units, and the corners of the outer reinforced concrete layer units are of fillet structures.
The outer-coated reinforced concrete layer units adopt a compression-resistant tension-free design, namely, four corners of each outer-coated concrete layer unit adopt a fillet design, gaps are reserved between the outer-coated concrete layer units and the steel tube concrete bundles and between adjacent outer-coated concrete layer units, and damping materials are filled in the gaps. Due to the design, the outer concrete coating is not directly connected with the steel tube concrete bundles on two sides, and the outer concrete coatings on the top and the bottom have smaller cross-sectional areas, so that the outer concrete coating does not directly bear horizontal load and cannot generate or generate smaller horizontal tension-compression deformation; and then make outsourcing concrete layer only bear vertical load, great promotion the vertical bearing capacity and the anti-seismic performance of wall body.
The concrete-filled steel tube bundle comprises six concrete-filled steel tube bundle units, and the number of the two sides of the wall body is three respectively.
The steel pipe concrete bundle is a wall edge constraint component and consists of profile steel and concrete poured therein, and the thickness of a single steel pipe concrete bundle unit is equal to that of the wall, so that the wall is convenient to assemble and construct; and the other four steel tube concrete beam units extending out of the plane improve the bending resistance, torsional rigidity and overall stability of the wall body.
The damping interlayer and the filled damping material are high damping rubber materials or foamed aluminum materials.
The thickness of the damping interlayer is 10-20 mm. The hysteresis energy consumption of the rubber material is utilized to convert the mechanical energy generated by the structural vibration into internal energy, thereby reducing the dynamic response of the structure and simultaneously increasing the out-of-plane anti-explosion and anti-impact performance of the wall body.
On one hand, the filled damping material can avoid direct contact between adjacent outer concrete layer units and between the outer concrete layer and the steel tube concrete bundle, so that the outer concrete layer does not directly receive horizontal load, namely, the influence of horizontal tension on the outer concrete layer is reduced. On the other hand, the filled damping can also play a damping role, and the reaction of the wall under the action of earthquake or explosion is reduced. In addition, the filled damping is flexibly arranged, if bolts are required to be arranged on the top plate and the bottom plate to connect the upper wall body and the lower wall body, the bolts can be arranged firstly, and then the rest gaps are filled with damping materials.
A plurality of bolt holes are formed in the corresponding positions of the steel plate layer, and the constraint pull rod assembly penetrates through the steel plate layer through the bolt holes and is connected with the steel plate layer in an anchoring mode through bolts.
The restraint pull rod assembly comprises a restraint pull rod and a plurality of screw caps, and the size of the restraint pull rod is matched with the size of a hole formed in the steel plate layer. The spacing of the restraint pull rods is not more than 100mm, the length of the restraint pull rods is equal to the spacing between two steel plates of the steel plate layer plus the thickness of the outer concrete layer on two sides to the thickness of the outer concrete layer, the thickness of the outer concrete layer is about 30mm, namely the restraint pull rods extend into the outer concrete layer in the thickness direction and are welded with a reinforcing mesh in the outer concrete layer to form a reinforcing cage, and the integrity of the wall body is enhanced.
The top plate and the bottom plate are steel plates, and the thickness of the top plate and the bottom plate is 25-35mm, preferably 30 mm. The top plate and the bottom plate are in direct contact with the outer concrete layer. The purpose is to transmit the vertical load to the outer concrete layer and exert the compression resistance of the outer concrete layer. In addition, the top plate and the bottom plate play the roles of top sealing and bottom sealing, and meanwhile, the standardized steel plates are also beneficial to the connection and assembly between the walls.
The connecting component disclosed by the invention is used for vertical connection, so that the defect of reduced bearing capacity caused by the embedded damping interlayer can be overcome, and the shear-resistant bearing capacity is improved.
Of course, the foregoing is only a preferred embodiment of the invention and should not be taken as limiting the scope of the embodiments of the invention. The present invention is not limited to the above examples, and equivalent changes and modifications made by those skilled in the art within the spirit and scope of the present invention should be construed as being included in the scope of the present invention.
