Description
Technical field
The present invention relates to the vertical method of attachment of fabricated shear wall, belong to interface drum that a kind of recruitment shape steel is connected with steel pipe protruding and be provided with the vertical method of attachment of assembling shear wall of bending reinforcing steel bar.
Background technology
Connection in assembling concrete shear wall structure system between each precast shear wall member is key link, at present, the vertical modes such as main employing sleeve connects, the connection of slurry anchor of installing of assembly concrete shear wall, level of processing and the required precision of these connected modes to member is high, or work progress impact loaded down with trivial details, that be subject to construction quality is large, cost is high, and at concrete joint surface, ftracture too early, easily occur even slippage of straight joint.
Summary of the invention
The object of the present invention is to provide the vertical method of attachment of a kind of easy construction, cost fabricated shear wall relatively low, that have better performance, to solve, the work progress that traditional shear wall method of attachment exists is loaded down with trivial details, cost is high, the problems such as straight joint easily appear in concrete joint surface.
The technical solution used in the present invention is as follows:
Work shape steel and steel pipe framework interface drum are convexly equipped with diagonal reinforcement assembling shear wall, the protruding interface of drum of the work shape steel arranging bottom upper strata precast shear wall mainly comprises, the vertical distribution reinforcement of body of wall, body of wall horizontal distribution reinforcing bar, structure hole, body of wall bottom; Lower floor's precast shear wall mainly comprises the protruding interface of drum at the vertical distribution reinforcement of steel pipe, body of wall, body of wall horizontal distribution reinforcing bar that top arranges, structure hole, body of wall top; Between levels body of wall, be ater-casting, horizontal reinforcement and bending reinforcing steel bar are set in ater-casting.
Pre-buried work shape steel dimensions should be supporting with steel pipe sizes, and 45 degree breach are cut in work shape steel termination, facilitates it to insert in steel pipe.
Pre-buried work shape steel extension elongation should be identical with ater-casting height, and pre-buried steel pipe extension elongation is roughly the half of ater-casting height.
Hole is left in steel pipe both sides, and the hole length of side or diameter dimension must not be less than rear pouring concrete maximum size of coarse aggregate.
Precast wall body upper and lower surface is that new-old concrete bonding surface place arranges special matsurface, and the height of matsurface drum projection is not less than 10mm.
Reserved upper and lower elongated structure hole in precast wall body, structure bore dia is not less than 100mm.
Levels body of wall vertical reinforcement extension elongation must not be less than the colligation lap length of code requirement.
Described work shape steel and steel pipe framework interface drum are convexly equipped with the practice of diagonal reinforcement assembling shear wall, carry out as follows:
A precast wall body, the docking of b levels body of wall, c concreting.
During precast shear wall, bilateral symmetry is arranged horizontal distribution reinforcing bar and vertical distribution reinforcement, and middle part service sleeve, longitudinally connects body of wall, the pre-buried work shape steel in body of wall bottom, body of wall top embedded steel tube; Concreting, precast shear wall upper and lower surface is shaped to the interface of tape drum projection by template, then extracts sleeve pipe out, forms structure hole; By the downward concreting in structure hole in precast shear wall, form ater-casting; Before structure hole is watered completely, stop fluid concrete, wait until when more last layer body of wall is built and fill up.
When precast wall body connects, top work shape steel inserts in the steel pipe of bottom, and at corresponding bolt hole, place connects with bolt; The reserved vertical reinforcement of levels body of wall overlaps in the colligation of place, ater-casting, and becomes reinforcing cage with the horizontal reinforcement colligation arranging herein.
The method that the present invention has adopted structural steel connecting member and overlap joint reinforcing bar to combine, in upper strata precast shear wall bottom, work shape steel is set, at lower floor's precast shear wall top, steel pipe is set, after docking, with bolt, connect again, reserved vertical distribution reinforcement adopts colligation overlap joint, place, ater-casting arranges bending reinforcing steel bar, and bonding surface is shaped to the protruding interface of drum by template in addition.
Concrete joint surface shear behavior is determining structural integrity, bearing capacity and the anti-seismic performance after splicing.This precast shear wall upper and lower surface is shaped to the protruding interface of drum (concavo-convex size is not less than 10mm) by template, can be better and rear pouring concrete combination, strengthen its shearing resistance effect, and improve the integrality performance of the structure after shear wall splicing simultaneously.
Precast wall body adopt top work shape steel to insert in the steel pipe of bottom and with bolt further fixing mode connect, can not only strengthen interface shearing-resistance effect, also can make shear wall under curved scissors effect, bring into play better unbending, prevent that interface, shear wall two ends from too early tensile failure occurring and accelerating shear failure.
The vertical distribution reinforcement of levels body of wall, at place, ater-casting colligation overlap joint, has been avoided the loaded down with trivial details work progresss such as sleeve grouting, has improved speed of application.Because work shape steel is elongated at place, ater-casting, and steel pipe only some, at steel tube end part, form plane of weakness, bending reinforcing steel bar is set one herein, can make up the shear-carrying capacity of weakness, while effectively alleviating shear failure, diagonal crack carries out simultaneously.
Place, ater-casting configuration template carries out shutoff, by the structure hole concrete perfusion of upper strata body of wall, concrete fills up the space between ater-casting and work shape steel and steel pipe, before watering completely, circular hole stops concrete perfusion, wait until when more last layer body of wall is built and fill up, strengthen contacting between ater-casting and precast wall body, stop interface crack and slide under shearing action.
