Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] The present invention includes a first prefabricated shear wall 1 and a second prefabricated shear wall 2. The two prefabricated shear walls have a joint 10 of 15mm, and both have notches, and the two notches are cast-in-place concrete 3 , the first hidden column stirrup 4 at the cast-in-place notch is placed after the two prefabricated wallboards are assembled. The first prefabricated shear wall 1 has a 30 mm thick straight section thin arm 8 and a first horizontal steel bar 5, the straight section thin arm 8 acts as a formwork, and the first horizontal steel bar 5 extends to the edge of the straight section thin arm 8 for bending, The straight length after bending is not less than 10d (d is the diameter of the horizontal steel bar).

[0014] The second prefabricated shear wall 2 has a 30mm thick L-shaped thin arm 9, a second horizontal steel bar 6 and a second con...

Abstract

The invention discloses a horizontal joint of an L-shaped shear wall. The horizontal joint comprises a first precast shear wall and a second precast shear wall. A first notch is arranged on a joint side of the first precast shear wall and is provided with a straight thin wall, a second notch is arranged on a joint side of the second precast shear wall and is provided with an L-shaped thin wall, a seam is reserved at connection of the first precast shear wall and the second precast shear wall, cast-in-site concrete is arranged in the first notch and the second notch, a first embedded column hoop and an embedded column vertical reinforcing steel bar are arranged in the cast-in-site concrete, a second embedded column hoop and a second horizontal reinforcing steel bar are arranged in the second precast shear wall, the second horizontal reinforcing steel bar extends to the edge of the L-shaped thin arm to bend, a first horizontal reinforcing steel bar is arranged in the first precast shear wall, and the first horizontal reinforcing steel bar extends to the edge of the straight thin wall to bend. The whole L-shaped shear wall is high in external force bearing, and the structure of the joint is simple in structure, convenient to construct and low in cost.

Description

technical field [0001] The invention relates to a horizontal connection node of an L-shaped shear wall, which belongs to the technical field of building structures. Background technique [0002] Shear walls are walls made of reinforced concrete. A structure composed of shear walls that bears vertical and horizontal actions is called a shear wall structure. The shear wall has a large anti-lateral stiffness, and it is mainly used to resist horizontal action and bear vertical action; the wall is also used as a maintenance and building separation component. The shear wall structure can be built very high and is mainly used for residential construction with 12-30 floors. The shear wall structure is a structure in which reinforced concrete wall panels replace the beams and columns in the frame structure as the main load-bearing components of the building. Because the horizontal shear force that high-rise buildings have to resist is mainly caused by earthquakes, compared with ot...
