Description
Technical field
The utility model is related to a kind of shear wall, the more particularly to attachment structure of shear wall and concrete secondary beam.
Background technology
Shear wall is to be primarily subjected to horizontal loading and the vertical lotus that wind load or geological process cause in house or structures
The wall of load, prevents structure shear from destroying, and is typically made by armored concrete.In following kind of engineering, it is desirable to shear wall
Poured prior to floor beam：
1st, the building of high-rise frame core wall structure, when building, is accelerating construction progress, the concrete core cylinder of high building
Shear wall is generally using the arrangement and method for construction of creeping formwork so that the contignation 3 ~ 5 of the advanced flooring of construction speed of Core Walls Structure shear wall
Layer.
2nd, the clear-water concrete structural wall of multilayer structure, to strengthen the airtight performance of template, is prevented in construction
Spillage, it is ensured that wall associative perception, it is desirable to after completing the overall pouring construction of dry concrete wall, then the building for carrying out outside functional areas
The construction of face beam slab.
In said structure, floor beam need could be constructed after shear wall concrete reaches preset strength, shear wall with it is rear
The node of casting concrete floor beam is a difficult point, and generally for this difficult point is avoided, floor beam generally selects girder steel, uses
The pre-embedded steel slab in shear wall, girder steel and pre-buried plate weld or bolted method, between such shear wall and floor beam
Connecting node is easier to treatment.But the cost of steel structure floor is higher.
When flooring secondary beam uses reinforced concrete structure, the connection of the shear wall and the secondary beam of after-pouring that first pour at present
The processing method of node is：
First pouring reinforcement concrete shear wall, after shear wall concrete reaches preset strength, by concrete secondary beam longitudinal direction
Reinforcing bar plants concrete shear within the walls in the way of bar planting, afterwards digs the contact surface of shear wall surface and concrete secondary beam
Hair, and the contact surface after dabbing is cleared up.Colligation concrete time beam steel simultaneously sets up template, last casting concrete secondary beam
And conserve.
Shortcoming is stated in the presence of shear wall and the connecting node of the secondary beam of after-pouring：
1st, concrete secondary beam longitudinal reinforcement is that concrete shear is planted in the way of bar planting within the walls, is needed during bar planting
Bar planting hole is opened up on concrete shear force wall.Reinforcing bar in shear wall is easy to be destroyed when bar planting hole is opened up, especially secondary beam
Position be exactly in when on shear wall sleeper position, the missing of reinforcing bar will bring hidden danger to the security of structure in sleeper.
2nd, bar planting is a kind of technology being bonded in reinforcing bar by chemical constitution glue in bar planting hole, to the quality of structure glue with
And the operating technology requirement of operator is higher, the quality control at scene is more difficult.
3rd, the vertical force of concrete secondary beam is to bond to pass to shear wall by the contact surface of secondary beam and shear wall, although
Dabbing treatment has been carried out to contact surface, but the reliability of the cohesive force of the contact surface of new-old concrete is also to be studied, secondary beam
Root easily becomes the weak spot of structure, when especially the larger load of secondary beam span is heavier, the safety stock of this connecting node
It is not enough.
4th, this node easily produces crack in stress at the contact surface of concrete secondary beam and shear wall, and influence is outer
See effect.
The content of the invention
The utility model technical problem to be solved first be to provide a kind of power transmission directly, possess reliable stress performance
The attachment structure of shear wall and after-pouring concrete secondary beam.Therefore, the utility model uses following technical scheme：
The attachment structure connects and vertical reinforcement and level is set in shear wall and after-pouring concrete secondary beam, the wall
Reinforcing bar, reserves pouring basin, concrete secondary beam of the shear wall in after-pouring concrete secondary beam after secondary beam in the attachment structure
Longitudinal reinforcement correspondence position sets connecting parts, and the collar extension of the connecting parts is flushed exposed to shear wall body surface and with metope,
Horizontal reinforcement and vertical reinforcement in wall expose to pour in the rear and stay rooved face.
Further, the after-pouring concrete secondary beam is provided with concrete secondary beam longitudinal reinforcement, and the concrete secondary beam is indulged
Mechanically connected with the collar extension of the connecting parts to reinforcing bar, the after-pouring concrete secondary beam is provided with the vertical muscle of anchoring, the anchoring is indulged
Muscle is mechanically connected with the internal orifice of the connecting parts, and in shear wall inner bending anchoring.
Further, being poured after described stays the width of groove fewer 50-100 millimeters than the width of after-pouring concrete secondary beam, after pour
Stay the height of groove fewer 150-200 millimeters than after-pouring concrete time depth of beam, after pour that to stay the depth of groove be 30 millimeters.
, in colligation, concrete cover to reinforcement thickness takes 30 for the shear wall horizontal reinforcement and shear wall vertical reinforcement
Millimeter.
Poured after described and stay groove to be located at secondary beam installation node middle part.
As a result of the technical solution of the utility model, the utility model is using concrete secondary beam longitudinal reinforcement by pre-
The connecting parts connection buried, is anchored directly to concrete shear within the walls, and the concrete shear force wall that pour completion will not be caused
Damage.Pour afterwards and stay shear wall horizontal reinforcement and shear wall vertical reinforcement in groove to expose, improve the contact surface of new-old concrete
The reliability of cohesive force, after pour stay groove presence make after pour secondary beam and be embedded into inside shear wall, it is ensured that the root of secondary beam with cut
Globality between power wall, this node is especially suitable for being used in the heavier shear wall of the larger load of span with after-pouring secondary beam
In connecting node, the construction quality of node structure is easily controlled, and with comparatively ideal outward appearance.
