Background
Shear walls are important components of assembled high-rise and super high-rise concrete buildings, and at present, the assembled shear walls at home and abroad mainly adopt two modes, namely a full-section prefabricated reinforced concrete shear wall and a double-faced superposed shear wall, wherein the double-faced superposed shear wall is increasingly used due to the advantages of good structural performance, low manufacturing cost and the like.
Traditionally, a double-sided superimposed shear wall is made up of a first wall panel, a second wall panel and a steel reinforcement cage connected between the first wall panel and the second wall panel. The more common forming and manufacturing modes are two types: firstly, manufacturing two steel bar meshes and connecting tie bars, and pouring and forming a first wallboard and a second wallboard in turn in a turning mode; however, due to the limitation of the concrete construction process, the size of a single double-sided superposed shear wall cannot be very large, so that the construction efficiency of the fabricated concrete building is influenced, and the manufacturing mode uses a large amount of steel and the field welding workload is large, so that the manufacturing cost is high; the other type is that two reinforcing mesh sheets are manufactured respectively, one reinforcing mesh sheet is provided with a reinforcing truss or a connecting tie bar, a first wallboard is poured and formed firstly, then the reinforcing truss or the connecting tie bar of the first wallboard is pressed into concrete of a second wallboard before the second wallboard is poured and initially set, and therefore the two wallboards are connected into a whole in a pulling mode. However, the depth of the steel bar truss or the connecting tie bar pressed into the second wallboard is limited, and the steel bars of the two wallboards are not connected, so that the bending rigidity of the formed double-sided superposed shear wall is poor, and the structural stability and reliability are weak.

With continued reference to fig. 4 and 6, in one embodiment, first prefabricated wall panel 10 and second prefabricated wall panel 40 are identical in construction and are arranged in mirror image. Specifically, the first prefabricated wall panel 10 includes a first prefabricated panel 11, and a first longitudinal bar 12 embedded in the first prefabricated panel 11, and the first steel bar truss 20 includes a first horizontal steel bar 21 embedded in the first prefabricated panel 11 and arranged to intersect with the first longitudinal bar 12, a first truss web rib 22 connected to the first horizontal steel bar 21 and extending perpendicularly out of the first prefabricated panel 11, and a first chord member steel bar 23 connected to the first truss web rib 22. The first longitudinal bars 12 and the first horizontal bars 21 are vertically arranged and fixed into a whole in a welding or binding mode to form the steel mesh sheet, namely, the steel skeleton of the first prefabricated panel 11 is formed. It should be noted that the steel mesh is mainly because the thickness of the first prefabricated panel 11 is small, and the thickness is usually 40mm to 90 mm. First truss web reinforcement 22 just can be connected fixedly through first horizontal reinforcement 21 and first vertical muscle 12, realizes that first steel bar truss 20 is connected fixedly with first prefabricated wallboard 10 pre-assembly, and first chord member reinforcing bar 23 then stretches into through first truss web reinforcement 22 and pours the chamber 70 in to can fully combine with the concrete, and then can improve coincide shear wall's structural strength and bending stiffness. The second prefabricated wall panel 40 comprises a second prefabricated panel 41 and a second longitudinal bar 42 embedded in the second prefabricated panel 41, and the second steel bar truss 50 comprises a second horizontal steel bar 51 embedded in the second prefabricated panel 41 and arranged to intersect with the second longitudinal bar 42, a second truss web rib 52 connected with the second horizontal steel bar 51 and extending perpendicularly out of the second prefabricated panel 41, and a second chord steel bar 53 connected with the second truss web rib 52; the first truss web 22 and the second truss web 52 are horizontally and longitudinally spaced apart in an overlapping arrangement. Since the structural composition and the component arrangement of the second prefabricated wall panel 40 are the same as those of the first prefabricated wall panel 10, the same technical effects as those of the first prefabricated wall panel 10 can be obtained, and thus the description thereof is omitted.
However, in the above embodiment, the first truss web 22 and the second truss web 52 have a corrugated structure. By adopting the corrugated structure, the first truss web rib 22 and the second truss web rib 52 can be further increased in contact area with concrete, and the binding force is improved, so that the structural strength of the superposed shear wall is improved. Of course, in other embodiments, the first and second truss webs 22, 52 may have other configurations, such as arcuate, square wave, etc., and remain within the scope of this application.
As shown in fig. 2, it should be noted that, by arranging first steel-bar truss 20 and second steel-bar truss 50 in a longitudinally spaced-apart overlapping manner, it is possible to prevent interference of the two truss steel bars in the horizontal direction when first prefabricated wall panel 10 and second prefabricated wall panel 40 are assembled on site; secondly, the overlapping relation of the truss reinforcing steel bars can be continued to the two prefabricated wall boards, the binding force between the two prefabricated wall boards and the concrete in the longitudinal direction is improved, and the bending rigidity of the two prefabricated wall boards is further improved.
As shown in fig. 1, in particular, in order to be able to adapt to the different thicknesses of the superposed shear wall, the arrangement positions of the first chord reinforcing steel bars 23 and the second chord reinforcing steel bars 53 have flexible variability. In one embodiment, the first chord rebar 23 is proximate to or abutting the second prefabricated panel 41 and the second chord rebar 53 is proximate to or abutting the first prefabricated panel 11.

As shown in fig. 3, in another embodiment, when the wall thickness of the composite shear wall is greater than 400mm, the space of the casting cavity 70 becomes larger, the concrete slurry to be cast increases, and the first chord member 23 needs to be arranged to cross the thickness center line of the composite shear wall and to be close to the second precast panel 41; the second chord rebar 53 crosses the thickness centerline of the laminated shear wall and is positioned proximate to the first precast panel 11. So, first chord member reinforcing bar 23 and second chord member reinforcing bar 53 can regard as interior drainage horizontal muscle, act as the fashioned skeleton role of concrete, improve the structural strength and the rigidity in superimposed shear wall middle part. Preferably, the thickness of the composite shear wall is divided into three equal parts, and the first chord reinforcement 23 is positioned at one of the three equal parts of the wall thickness and across one half line of the wall thickness, with the first chord reinforcement 23 positioned adjacent to the second precast panel 41. Similarly, second chord rebar 53 is also positioned at the other trisection of the wall thickness and across half-way of the wall thickness, with second chord rebar 53 positioned adjacent first precast panel 11. Through the structural arrangement, the first truss web rib 22, the second truss web rib 52, the first chord member steel bar 23 and the second chord member steel bar 53 are uniformly arranged in the middle areas of the first prefabricated panel 11 and the second prefabricated panel 41, so that the combination uniformity of the first truss web rib, the second truss web rib, the first chord member steel bar 23 and the second chord member steel bar 53 with concrete can be ensured, and further, the balance of the mechanical properties of all parts of the superposed shear wall is ensured.

In this way, the current superposed shear wall can be anchored into another adjacent superposed shear wall through the first anchoring section 121 and the second anchoring section 421, which extend out of the ends, so as to realize quick and reliable assembly and connection between the superposed shear walls.
