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 reinforcing structure for a rear opening in a shear wall and a construction method of the reinforcing structure. The reinforcing structure comprises an original wall, a floor slab and a structural steel frame for reinforcing, wherein the structural steel frame comprises steel angles and flat steel and covers the edge of the rear opening, and the steel angles and the flat steel are fixed at the rear opening through anchor bolts and high-strength plate bolts; and the steel angles are arranged on two sides of the wall, the vertical and horizontal junction position of the steel angles is welded and outwards extends along the opening, vertical legs are cut off from the extending part, the steel angles on two sides are connected through batten plates, the batten plates and the steel angles are in groove welding, the contact positions of the bottoms of the steel angles and the floor slab adopt flat groove welding through local cut steel angle lacing bars and the steel angles on two sides, and the flat steel is arranged on the floor slab on two sides of the wall. Cut-off reinforcing steel bars in the original wall are reinforced with plug welding matched with the structural steel frame after the ends of the reinforcing steel bars are reserved, anchoring steel angles are added between the bottom of the floor slab and the lower wall, two legs attached to the wall surface are connected by high-strength bolts and connected with the floor slab and the flat steel through the high-strength plate bolts.
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 ...
