Problems solved by technology
[0004] However, the above-mentioned commonly used shear wall production methods determine that only one side of the steel mesh on the prepared shear wall is reliably connected to the truss reinforcement, while the other side of the steel mesh is not connected to the truss reinforcement. , it is difficult to form an effective lateral constraint between the prefabricated wall panels on both sides, which greatly weakens the connection performance between the steel truss and the steel mesh in the prefabricated wall panels, and reduces the seismic performance of the overall structure of the shear wall
At the same time, due to the poor lateral restraint between the prefabricated wall panels on both sides, when the concrete in the middle cavity is poured, the lateral effect on the prefabricated wall panels on both sides is significant, which affects the stability of the entire laminated wall to a large extent sex

Embodiment Construction
[0044] Such as Figure 1 to Figure 3 As shown, the double-sided laminated shear wall with two-way connection ties of the present invention includes prefabricated panels on both sides of the shear wall, a steel truss 2 and / or connection ties 3 arranged between the two prefabricated panels, and cast-in-place concrete6 between two prefabricated panels.
[0045] The prefabricated panel includes a first panel 11 and a second panel 12, and a first reinforcing mesh sheet 51 and a second reinforcing mesh sheet 52 are respectively laid in the first panel 11 and the second panel 12.
[0046] The connecting bars include a first bar 3 and a second bar 4. The shapes of the first bar 3 and the second bar 4 can be the same or different, and they are arranged in groups of two and overlapped, such as Figure 4 to Figure 8 shown.
[0047]The first tie bars 3 are linear or spiral, arranged perpendicular to the first panel 11, evenly arranged in the first panel 11, and can be arranged in a matr...

The invention relates to the technical field of superimposed shear walls and discloses a double-sided superimposed shear wall with bidirectional connecting tensile reinforcements and a construction method thereof. The superimposed shear wall with the bidirectional connecting tensile reinforcements comprises prefabricated panels on both sides of the shear wall and cast-in-place concrete between thetwo prefabricated panels, and further comprises the connecting tensile reinforcements arranged between the two prefabricated panels; the connecting tensile reinforcements comprise first tensile reinforcements and second tensile reinforcements, wherein the first tensile reinforcements and the second tensile reinforcements are arranged in pairs and overlapped, and are arranged perpendicular to theprefabricated panels. The double-sided superimposed shear wall with the bidirectional connecting tensile reinforcements is simple in structure, beneficial for mechanized and batch production, high inlateral restraint and good in anti-seismic performance.
Description
technical field [0001] The invention relates to the technical field of laminated shear walls, in particular to a double-sided laminated shear wall with two-way connecting ties and a construction method thereof. Background technique [0002] The double-sided laminated shear wall structure is a semi-prefabricated and semi-cast-in-place concrete structure, which absorbs the advantages of cast-in-place concrete structures and precast concrete structures. It has the characteristics of high-quality prefabricated components and good integrity of cast-in-place connections, and is suitable for housing industrialization demand, has been more and more used in the field of construction. [0003] At present, the production methods of double-sided laminated shear walls at home and abroad generally include arranging steel bars, pouring concrete on one side, vibrating the concrete, curing, pouring concrete on the other side, turning over the poured concrete slab and pressing it into a prede...
