The present invention utilizes the overlap joint of band pier nose vertical reinforcement certain-length, realizes the power transmission continuity of shear wall edge member vertical reinforcement, guarantees the supporting capacity of shear wall; Through surrounding expanded metal lath cavity pipe or wire gauze cavity pipe, continuous rectangular spiral hoop and prefabricated shear wall slab horizontal reinforcement; The edge concrete members is formed multiple constraint; Significantly improve concrete deformability; Guarantee the ductile performance of shear wall, and can further improve the overlap joint switching performance of band heading vertical reinforcement.
Adopt band heading vertical reinforcement in the shear wall edge member scope of the present invention, can improve its anchoring property, and can reduce overlap joint connection length, irritate pea gravel concreten (or grouting is expected) thereby reduce the back.
When wallboard of the present invention is prefabricated; Horizontal gib head lacing wire is set between the rectangular enclosure pipe; And with the reliable drawknot of shear wall horizontal reinforcement, realize edge member and the prefabricated overall operation of setting up wallboard, and avoid the edge member precast concrete prefabricated and afterwards concrete placing build the damage in the process.
As preferably, according to the shape and size of shear wall edge member, a plurality of rectangle steel expanded metals cavity pipes or wire gauze cavity pipe can be set flexibly, and fillet be set in rectangular enclosure limb portion, be convenient to the concrete trickling and build.
As preferably, the installation that bends inwards of the band heading vertical reinforcement of the prefabricated shear wall slab edge member of said lower floor has avoided the vertical reinforcement dislocation of prefabricated shear wall slab to arrange, simplifies precasting process.
Assembly concrete shear wall edge member joint construction of the present invention; Prefabricated shear wall slab layering is prefabricated, and prefabricated shear wall slab edge member adopts band heading vertical reinforcement, simultaneously; The top vertical reinforcement of prefabricated panel edge member stretches out certain-length; With the vertical reinforcement overlap joint of its prefabricated panel edge member bottom, upper strata, adopt a plurality of rectangle steel expanded metals cavity pipes or wire gauze cavity pipe to box out in the overlap joint scope, back perfusion pea gravel concreten (or contraction-free grouting concrete) with flexible size.Through reinforcing bar heading and certain lap length, satisfy the lapping and anchoring requirement of vertical reinforcement, realize the continuous power transmission of vertical reinforcement; In rectangle steel expanded metals cavity pipe or wire gauze cavity pipe, overlap joint vertical reinforcement arranged outside continuous rectangular spiral hoop; Expanded metal lath through surrounding the rectangular enclosure pipe or wire gauze, the multiple constraint of rectangular spiral hoop, prefabricated shear wall slab horizontal reinforcement and horizontal lacing wire continuously strengthen the concrete restraint performance of edge member.
Beneficial effect:(1) upper and lower layer prefabricated panel edge member vertical reinforcement of the present invention is through reinforcing bar heading and certain lap length; Realize the continuous force request of edge member vertical reinforcement; The reinforcing bar heading can effectively reduce lap length; Irritate pea gravel concreten amount (or irritating amount of slurry) thereby reduce the back, improve speed of application; (2) in expanded metal lath cavity pipe or the wire gauze cavity pipe, the continuous rectangular spiral hoop of overlap joint vertical reinforcement arranged outside; Expanded metal lath or wire gauze with the rectangular enclosure pipe; Back concrete placing to edge member provides strong constraint; When improving the deformability of irritating pea gravel concreten in the back, can further improve the overlap joint switching performance of vertical reinforcement; (3) according to the shape of edge member; The size and the number of rectangle steel expanded metals cavity pipe or wire gauze cavity pipe can be set flexibly; Roughness that the mesh of dependence expanded metal lath or wire gauze forms and wallboard are arranged at the wallboard horizontal reinforcement and the horizontal lacing wire of cavity pipe outer wall when prefabricated, guarantee the stressed jointly of each cavity pipe of its edge member, edge member and shear wall general place; (4) the prefabricated thin-wall plate between the rectangular metal mesh is provided with horizontal gib head lacing wire and strengthens, and avoids prefabricated and builds the concrete damage of process hollow lumen outer wall; (5) the edge member vertical reinforcement need not to shift to install, and after bending inwards through lower floor's prefabricated panel edge member vertical reinforcement, inserts in the metal bellows, with topmost edge member vertical reinforcement overlap joint, thereby simplifies precasting process.
