The purpose of this utility model is for the deficiencies in the prior art, provides a kind of prefabrication and assembly construction concrete shear force wall edge joint position syndeton.
The technical solution adopted in the utility model is: a kind of prefabrication and assembly construction concrete shear force wall edge joint position syndeton, comprise top, shear wall upper strata precast wall body, bottom, shear wall upper strata cast-in-situ wall, shear wall lower floor precast wall body, concrete short column or angle steel, pouring hole, vertical reinforcement and sleeper district stirrup, the vertical reinforcement of described shear wall upper strata top precast wall body and shear wall lower floor precast wall body is in the cast-in-situ wall inside lap of bottom, shear wall upper strata, in the cast-in-situ wall of bottom, shear wall upper strata, sleeper district is provided with sleeper district stirrup, work the described concrete short column of building temporary support effect or angle steel is arranged in the cast-in-situ wall of bottom, shear wall upper strata, pouring hole is provided with between the Qiang Zhi distribution reinforcement district reinforcing bar of top, described shear wall upper strata precast wall body.
A method of attachment for above-mentioned prefabrication and assembly construction concrete shear force wall edge joint position syndeton, comprises the following steps:
1) shear wall each layer body of wall employing top is prefabricated, bottom is cast-in-place; First the vertical reinforcement of top, shear wall upper strata precast wall body vertical reinforcement and shear wall lower floor precast wall body is overlapped in cast-in-place district;
2), during assembling, utilize concrete short column or angle steel as the temporary support of top, shear wall upper strata precast wall body;
3) arrange pouring hole between the Qiang Zhi distribution reinforcement district reinforcing bar of top, shear wall upper strata precast wall body, after treating that the overlap joint of above-mentioned vertical reinforcement completes, in pouring hole, concreting is to cast-in-place district and vibration compacting, forms bottom, shear wall upper strata cast-in-situ wall.
The utility model shear wall each layer body of wall top is prefabricated, and bottom is cast-in-place.During assembling, utilize precast concrete short column or angle steel as the temporary support of top, upper strata precast shear wall, support upper wall body, the logical high pouring hole concreting arranged by Qiang Zhi distribution reinforcement district, top extremely cast-in-place district vibration compacting.Concrete short column or angle steel according to top dry wall limb size and weight, can optimize short column size, quantity and spacing or angle steel model, quantity and bridging layout etc.Cast-in-place district is arranged at the stressed larger root of each story shear wall limb, and can arrange reasonable altitudes according to bar gauge and diameter.
The beneficial effects of the utility model: 1. utilize concrete short column or angle steel as the temporary support of upper wall body, reduce setting up of job site temporary support; 2. cast-in-place district is arranged at the stressed larger root of each story shear wall limb, by the reasonable setting of cast-in-place district height, can ensure overlap joint reinforcing steel bar bear continuity, thus guarantee the globality that this placement members is stressed; 3. cast-in-place district concrete monobloc cast makes piece moves, and improves rigidity and the supporting capacity of shear wall edge joint position; 4. utilize the pouring hole be arranged in upper wall body, ensure that the convenience of site operation.
