Compared with the prior art, the invention has the beneficial effects that:
1. When the combined connection mode of the buckling type connecting piece and the end connecting piece is adopted and the end connecting piece is in a replaceable connection mode, in the earthquake action process, when the tensile force born by the end of the wall body is not higher than the sliding threshold value of the friction plate and other parts, the friction plate and the clamping plate do not slide relatively, the buckling type connecting piece enables the upper fastener and the lower fastener to form a whole through the buckling piece squeezing device, horizontal shearing force under the earthquake action is effectively resisted, and the strength, the rigidity and the bearing capacity of the whole shear wall under the normal use state and the small earthquake action are fully ensured under the combined action of the buckling type connecting piece and the end connecting piece.
When the force born by the end part of the wall exceeds the sliding threshold value of parts such as friction plates and the like, the friction plates with long round holes and the clamping plates slide relatively to drive the connecting plates to deform, the end connecting pieces preferentially dissipate earthquake energy through sliding friction and metal deformation, and when a large earthquake occurs, the friction plates and the energy-consumption clamping plates of the end connecting pieces slide relatively more until the high-strength screw is limited by the long round holes of the friction plates, the screw and the hole walls are extruded, and the extrusion force and the friction force act together to improve the bearing capacity of the wall; meanwhile, gaps exist between the upper fasteners and the lower fasteners which are buckled and arranged in the middle of the wall body, friction extrusion is carried out under the action of a medium-intensity earthquake, metal deformation is generated to a certain extent, earthquake energy is further dissipated, the buckling piece squeezing device is still in a working state at the moment, the strength and the integrity of the buckling type connecting piece are maintained, and the shearing resistance of the shear wall is not greatly influenced;
Through the design, the end connecting piece is preferentially subjected to energy consumption under the conditions of small earthquake and medium earthquake, severe damage to the shear wall is prevented, and the end connecting piece and the buckling connecting piece jointly play the role of energy consumption during the medium strong earthquake, so that the grading and regional energy consumption according to the earthquake energy input is realized, and the bearing capacity, the ductility, the energy consumption capacity and other anti-seismic performances of the shear wall are improved.
2. When the end connecting piece is selected, a square placing cavity is arranged in the plastic hinge area of the basement to place the end connecting piece. The concrete shear wall foot area is often severely damaged by buckling of the steel bars and large-area stripping of concrete during an earthquake, so that the repair is difficult. The invention realizes the detachable connection by connecting the upper connecting seat and the lower connecting seat through the high-strength bolts, the connecting plates and the energy consumption clamping plates, when an earthquake happens, the connecting plates at two sides are subjected to metal deformation, the energy consumption clamping plates and the friction plates slide relatively to generate friction energy consumption, so that the earthquake energy is dissipated, the damage of the earthquake energy is concentrated in the end connecting pieces of the plastic hinge areas, the main body part of the concrete shear wall is protected to a certain extent, the connecting plates at two sides only need to be replaced after the earthquake, and the purpose of quick repair can be realized by fixing the energy consumption clamping plates again; after a major earthquake, the invention adopts a fully assembled connecting structure, so that the buckling type connecting piece can be disassembled simultaneously to replace the whole wall body seriously damaged by the main body under the necessary condition, thereby improving the reusability, reducing the cost of repairing after the earthquake and enhancing the maintainability after the earthquake.
3. The novel fully-assembled horizontal connecting structure is adopted, the replaceable energy-consuming end connecting piece is adopted at the wall end, and the buckling type connecting mode is adopted in the middle of the wallboard, so that the traditional bolt box type connecting mode is broken through, the problem that box type connection is difficult to align with a bolt hole from top to bottom is solved, the installation mode of pushing in from the side is changed, the installation fault-tolerant space is improved, the novel fully-assembled horizontal connecting structure is suitable for assembly type installation in a compact environment, and the installation construction difficulty is reduced; because of adopting fully-assembled connection, the installation is simple and convenient, the wet operation such as cement mortar is not required, reliable connection can be realized only by installing bolts and buckling piece squeezing devices, the difficulty of an assembly process is reduced, the pollution to the environment is reduced, the construction efficiency is improved, and the mechanization degree is high; meanwhile, the main stress members of the structure are all positioned on the outer side of the wall body concrete, so that the main stress members can be conveniently detected and monitored in the construction and use processes, the construction quality is ensured, and a basis can be provided for state monitoring under normal use and repair and identification after an earthquake.
4. The middle part of the wallboard adopts the upper fastener and the lower fastener to carry out preliminary double-hand-simulated buckling type connection, so that the out-of-plane instability of the wall body in the installation process can be prevented to a certain extent; the upper wall body and the lower wall body are horizontally pushed into and buckled with each other and then are connected and fixed by adopting the embedded screw rods, and the design of the guide holes facilitates the guide positioning and fixing of the screw rods; after the buckling is finished, the first screw sleeve and the second screw sleeve can move back by rotating the adjusting screw, so that the first screw sleeve and the second screw sleeve are fully abutted against the upper fastener and the lower fastener, the horizontal shearing force is effectively resisted, and the shearing damage at the joint of the shear wall is prevented; when encountering strong shock, the wall body is subjected to larger displacement, but the rigidity and the integrity of the buckling type connecting piece can be well guaranteed by the arrangement of the horizontal adjusting rod, on the premise that the upper buckle piece and the lower buckle piece which are arranged in a buckling mode are mutually extruded and rubbed to generate deformation, the energy brought by the earthquake can be well consumed, the energy consumption capability and the ductility of the fabricated concrete shear wall are effectively improved, and the good anti-seismic performance and the safe and reliable structure of the building are guaranteed to a certain extent. After earthquake, the buckled connecting piece is pre-pressed and fixed mainly through the modes of bolt fixing and rotary jacking, after earthquake, the wall body can be pushed out along the guide Kong Fanxiang after the earthquake is slightly loosened by only rotating the horizontal adjusting rod and the nut reversely, the disassembly and the replacement of the whole wall body are convenient, the end connection can be realized by only disassembling the bolts and the connecting steel plates, the advantage of easy assembly of the fully assembled connecting form is fully exerted,
5. When the fully assembled anti-seismic connecting piece is selected, the double-layer thin backing plate with smaller rigidity and the bolt with low strength are adopted for connection, and during anti-seismic, the double-layer backing plate is buckled and deformed before the yielding damage of the bolt by designing the size of the connecting end plate assembly hole and the thickness of the backing plate, so that the energy brought by the earthquake is dissipated to a certain extent, and the structure is ensured not to be subjected to brittle failure before the yielding damage of the bolt, and the sudden failure of the horizontal connecting piece is prevented; meanwhile, the assembly holes with larger sizes on the connecting end plates can also improve the fault tolerance rate of the components during assembly.
6. According to the invention, the initial rigidity of the shear wall can be effectively ensured through the fixed connection of the end connectors at the two sides of the wall, the problem that the horizontal joint openings of the end parts are overlarge when the buckling type connectors are singly used in an earthquake is avoided, the concrete at the wall foot is crushed, peeled and damaged too early, the ductility of the structure is improved, and the buckling type connectors are helped to fully exert the earthquake resistance.
