Power wall construction system, is vertically connected with joint structure method particularly to a kind of prefabricated assembled band concealed bracings overlapped shear wall.
Background technology
Prefabricated overlapped shear wall structural system (is connected two panels by lattice Steel bar rack by some prefabricated overlapping concrete walls sheets
Thickness is more than filling out the thickness component more than 100mm concrete composition in 50mm precast concrete thin plate, cavity), by various knots
Structure structure or device connect upper and lower wall sheet and form；Prefabricated overlapped shear wall structural system has that speed of application is fast, the construction period is short,
Environmental protection and making precision advantages of higher, in non-antidetonation area extensive application such as Europe.In recent years, domestic priority exists
The areas such as Anhui, Shanghai, Hunan are progressively promoted the use of.
The prefabricated overlapped shear wall structure that China promotes at present uses Germany technology, does not consider that geological process affects,
Therefore China's antidetonation area should not be directly applied to；The connected mode of existing prefabricated overlapped shear wall structure is broadly divided into two kinds: its
One is to arrange breach on pre-cast concrete walling sheet both sides, upper strata, the embedded bar on both sides and breach bar connecting in lower floor's body of wall,
Central region is connected by the embedded bar in wall sheet, then fills concrete in wall sheet cavity by upper and lower layer wall connecting
Integral；It two is at the pre-buried cyclic reinforcing rib leaked outside of prefabricated reinforced concrete wall enclosure, and lower floor's wall pre-embedded connects steel
Muscle overlaps through cyclic reinforcing rib indirectly with upper wall body.Use above-mentioned method of attachment it cannot be guaranteed that body of wall vertical reinforcement has up and down
Effect connects, and connecting joint point reliability is not good enough, deformability is poor, constrains the overall shock resistance of prefabricated overlapped shear wall structural system
Can, compared with integral cast-in-situ shear wall structure, the connection between existing prefabricated overlapped shear wall upper and lower wall sheet remains weak link.
Summary of the invention
This utility model, for the deficiencies in the prior art, proposes by high-strength bolt connected mode prefabricated assembled overlapping
Shear wall structure is attached assembly, and band concealed bracings overlapped shear wall wall sheet of the present invention is prefabricated in the factory, and wall sheet corner sets
Put breach and future insufficiency reinforcing bar, convex region vertical reinforcement and the upper and lower layer junction steel plate being reserved with bolt hole in the middle part of wall sheet
Welding, during site operation, wall sheet corner breach reserved steel bar overlaps indirectly with being connected reinforcing bar, upper and lower prefabricated overlapped shear wall wall sheet
Convex position is then vertically connected with steel plate by high-strength bolt anchoring and is allowed to form entirety.
This utility model is achieved through the following technical solutions:
A kind of prefabricated assembled band concealed bracings overlapped shear wall, including the reinforced concrete sandwich wall arranging band concealed bracings

The prefabricated overlapping wall sheet certain distance of layer；
The reinforced concrete sandwich shear wall of described band concealed bracings, in its X-shaped steel diagonal brace and sleeper, square steel tube uses L-angle steel
Welding；
Described band concealed bracings overlapped shear wall wall sheet, point inside and outside two pieces of precast concrete thin plates, lattice is set between thin plate
Reinforcing bar；
Described lattice reinforcing bar plays precast concrete thin plate effect inside and outside drawknot；
Described prefabricated assembled band concealed bracings overlapping body of wall is overlapped by breach reinforcing bar and connection reinforcing bar indirectly in indentation, there,
Middle part convex wallboard vertical reinforcement welds with upper and lower layer junction steel plate respectively, junction steel plate prepared screw-bolt hole；
High-strength bolt being vertically connected with prepared screw-bolt hole is connected through between described band concealed bracings overlapped shear wall wall sheet
Steel plate bolts；
Compared with the prefabricated construction using existing interconnection technique, prefabricated by connected mode of the present invention is folded
Combination shearing wall structure can ensure that upper and lower body of wall vertical reinforcement effectively connects and formed overall coordination effect, connects power transmission at node
Approach is reliable, meets the weak element structure design concept requirement of strong node, and the overall anti-seismic performance of structure is substantially improved；Meanwhile, adopt
Easy with the on-site consolidation of the prefabricated overlapped shear wall structure of upper and lower junction steel plate bolt interconnection technique, can significantly play prefabricated dress
The advantage that distribution structure speed of application is fast, possesses great engineering practical value.
