Assembly interlocking prestressing force shear wall system and construction method thereof

Abstract

The invention discloses an assembly interlocking prestressing force shear wall system which comprises prestressing tendons 1, a cast-in-place foundation beam 2, sighting telescopes 4, combination wallboards 5, cast-in-place columns 3, a cast-in-place beam 15 and a cast-in-place floor slab 16. A concave-shaped frame is formed by the cast-in-place foundation beam 2 with a through hole 12 reserved and the cast-in-place columns 3. The combination wallboards 5 are embedded into the concave-shaped frame through the prestressing tendons 1. The sighting telescopes 4 are installed after the prestressing tendons are stretched and pulled. Then, the cast-in-place beam 15 and the cast-in-place floor slab 16 on a first floor and the cast-in-place columns 3 on a second floor are poured. A new concave-shaped frame is formed. Then, the combination wallboard 5 on the second floor is assembled. Construction of other floors is repetition of the process. Provided is a construction method of the assembly interlocking prestressing force shear wall system. The construction method comprises the steps of (a) preparation work, (b) foundation excavation, (c) pouring of foundation, the cast-in-place foundation beam 2 and the cast-in-place columns 3 on the first floor, (d) assembly of the combination wallboard 5 on the first floor, (e) pouring of the cast-in-place beam 15 and the cast-in-place floor slab 16 on the first floor and the cast-in-place columns 3 on the second floor, (f) assembly of the combination wallboard 5 on the second floor, and (g) construction on other floors.

Description

technical field [0001] The present application relates to a shear wall, more precisely an assembled interlocking prestressed shear wall system. Background technique [0002] At present, the shear walls, beams, and columns in construction projects are mostly cast-in-place. The cast-in-place shear walls are rigidly connected to the foundation and beams. On the one hand, the walls, foundation beams, and frame beams are limited. On the other hand, the wall has great lateral stiffness. Under the repeated action of earthquake load, the bending moment and shear force in the wall make it easy to form cross cracks, resulting in cracking of the shear wall and making the wall The bearing capacity of the body is reduced, and it is even destroyed in a major earthquake. Even if the damaged shear wall survives after the earthquake, its repair work is very difficult and uneconomical. In addition, cast-in-place shear walls require a large amount of formwork, and the construction speed is al...

Under the repeated action of earthquake load, the bending moment and shear force in the wall make it easy to form cross cracks, resulting in cracking of the shear wall and making the wall The bearing capacity of the body is reduced, and it is even destroyed in a major earthquake. Even if the damaged shear wall remains after the earthquake, its repair work is very difficult and uneconomical

In addition, cast-in-place shear walls require a large amount of formwork, and the construction speed is also greatly limited
