Problems solved by technology
[0003] Aiming at the situation that the door and window openings are added to the original anti-seismic wall in the anti-seismic reinforcement and reconstruction of old houses due to lighting and building function requirements, thereby weakening the bearing capacity of the shear wall in the original structure, a rear opening of the shear wall is proposed. Hole reinforcement structure and its construction method to solve the technical problem that the strength of the shear wall will not be weakened after the hole is opened

Embodiment Construction
[0031] A reinforcement structure with openings behind the shear wall, see Figure 1 to Figure 5 shown. Including the original wall 1 and the floor 2, the original wall 1 is provided with a rear opening 4, and also includes a steel frame for reinforcement. and the flat steel 6 are respectively fixed at the rear opening 4 by anchor bolts 8 and through-plate high-strength bolts 10 (such as figure 1 shown). Wherein, angle steel 5 comprises the angle steel 5 that is arranged on both sides and top side of rear opening 4, and the angle steel 5 on every side is two rows, is arranged in original wall body 1 inside and outside both sides respectively (such as figure 2 shown). The vertical and horizontal junctions of the angle steel 5 on both sides and the top side of the rear opening 4 are welded to each other, and the long limbs of the angle steel 5 attached to the wall extend outward along the rear opening 4 to form an extension 12 . The angle steel 5 long limbs attached to the w...

The invention relates to a rear opening reinforcement structure of a shear wall and a construction method thereof, comprising an original wall body, a floor slab, and a steel frame for reinforcement. The profiled steel frame is composed of angle steel and flat steel, which is wrapped around the edge of the door and window opening, and fixed at the rear opening by anchor bolts and high-strength bolts through the plate. The angle steel is arranged on both sides of the wall, and its longitudinal and horizontal junctions are welded together and should extend outward along the opening. The extension part should cut off the vertical limbs, and the angle steels on both sides are connected by patch plates. The contact between the bottom of the angle steel and the floor slab is welded with partial amputation angle steel strips, the angle steel on both sides and the cutout, and the flat steel is arranged on the floor on both sides of the wall. The cut steel bars in the original wall are left to be reinforced with drilled plugs and welded to the shaped steel frame. An anchor angle steel is added between the bottom of the floor and the lower wall, and the two limbs attached to the wall are connected with high-strength bolts and attached to the floor. The two limbs are connected with the floor slab and flat steel with high-strength bolts through the plate.
Description
technical field [0001] The invention relates to a reinforcement structure with openings behind a shear wall and a construction method thereof, belonging to the technical field of reinforcement and transformation. Background technique [0002] As the main wall in the house that bears the horizontal force generated by wind or earthquake, the shear wall is widely used in the building structure. However, when the existing buildings are reinforced and reconstructed by methods such as jacket reinforcement, the shear wall will be affected by the sunlight. and building function needs to open door openings and window openings, but the reinforcement and size of the shear wall have been fixed. If openings are opened for the shear wall due to the functional requirements of the owner, the load bearing capacity of the shear wall in the original structure will be greatly reduced Therefore, it is particularly important to take necessary reinforcement measures after the opening of the shear ...
