Description
Technical field
Building structure mounting technology field is the utility model is related to, is specifically related to a kind of the perpendicular of precast concrete shear wall
To overlap joint attachment structure.
Background technology
Precast concrete shear wall structure is a kind of structural system suitable for housing industrialization, fast with speed of application,
The characteristics of quality is easily controlled, and is saved the energy and water, is produced less building waste, and cost is relatively low；In addition, China is
Green building is greatly developed, the work progress of precast concrete shear wall structure has the characteristics of green construction, so sending out energetically
Exhibition precast concrete shear wall structure is the developing direction of following construction.
At present, vertically overlap joint connected mode is mainly reinforced bar sleeve grouting in the work progress of precast concrete shear wall
Connection and constraint slurry anchor overlap joint connected mode.The method safety of reinforced bar sleeve grouting connection vertical reinforcement is reliable, but sleeve stays in
The inside, cost is very high, and a reinforcing bar is to sleeve, and the bar diameter difference that sleeve diameter and needing connects is smaller, cuts
Reinforcing bar needs to be accurately positioned when power wall is equipped, and the bar diameter that sleeve connection technology needs is larger, and reserved reinforcing bar is short, spells
The correction of reinforcing bar deviation is more difficult during dress, and these all cause the problems such as connection workload is big, assembling construction speed is slow.Constraint slurry
The forming hole method of anchor overlap joint connected mode is to increase tie hoop outside built-in threaded steel pipe, again rotates threaded steel pipe after shaping
Extract out, and a reinforcing bar differs smaller to a hole, hole internal diameter and the bar diameter for needing to connect, reinforcing bar needs when shear wall is equipped
It is accurately positioned；So although cost decreases, this method tedious process, the bad control of technique, people is more consumed
Work；And the reinforcing bar length that needs are reserved is long, cost is still very high.
The content of the invention
The purpose of this utility model is exactly to solve the above-mentioned problems in the prior art, there is provided a kind of vertical overlap joint connection
Structure, fast using the precast shear wall low cost of the overlap joint attachment structure, assembling construction, connection workload is small.
To achieve the above object, technical solution of the present utility model is：A kind of precast concrete shear wall it is vertical
Overlap attachment structure, including on reserved multiple in more upper vertical reinforcements, more lower vertical reinforcements, upper strata precast shear wall bottoms
Small wedge-shaped hole to be provided, multiple injected holes and multiple slurry outlets under big；Every upper vertical reinforcement by two upper vertical bars side by side and
The upper horizontal bar composition of vertical bars end in connection two, every lower vertical reinforcement is by twice vertical bars ends of two lower vertical bars side by side and connection
The lower horizontal bar composition in portion；The upper vertical reinforcement stayed in wedge-shaped hole to be provided and the lower vertical reinforcement being inserted in wedge-shaped hole to be provided are taken
Connect；Injected hole and slurry outlet are all opened on the precast shear wall of upper strata, and injected hole is located at wedge-shaped hole to be provided lower end and reserved with wedge shape
Hole connects, and slurry outlet connects higher than wedge-shaped hole to be provided upper end and with wedge-shaped hole to be provided；In wedge-shaped hole to be provided, injected hole and slurry outlet
Fill strength cement-based grouting material or cement base high-strength grout.
Injected hole centre distance precast concrete shear wall wall bottom 3cm described above.
The lap of splice of upper and lower vertical reinforcement described above is not less than 200mm.
Wedge-shaped hole to be provided of the present utility model is big, and lower vertical reinforcement easily inserts hole to be provided, can improve precast shear wall
On-site consolidation speed；Slurry outlet can better control over compactness of grouting in wedge-shaped hole to be provided upper end, improve reinforcing bar and connect
Connect quality；Because two upper vertical bars are connected by upper and lower horizontal bar respectively with the end of two lower vertical bars, upper and lower vertical reinforcement intensity
Height, so the length of overlap joint can shorten, the length that lower vertical reinforcement stretches out lower floor's precast shear wall is short, and it is prefabricated to reduce lower floor
Disturbance of the shear wall in transport, hoisting process to reserved overhanging lower vertical reinforcement, reduces rectifying for the overhanging lower vertical reinforcement in scene
Positive workload, the on-site consolidation speed of precast shear wall is improved indirectly；The pre- of attachment structure is vertically overlapped using the utility model
Shear force wall reinforcing steel bar arrangement of reinforcement processed is small, can save the production cost of precast shear wall, and the engineering for reducing assembly of shear wall structure is made
Valency.In a word, the precast shear wall low cost of attachment structure overlapped using the utility model, assemble construction soon, connection workload is small.
