Description

Technical Field

[0001] The present invention belongs to the field of post-opening shear walls, and in particular relates to a post-opening shear wall opening wrapping type bonded steel reinforcement structure and a construction method. Background Art

[0002] Shear walls are the main shear walls in houses that withstand horizontal forces generated by wind or earthquakes. They are widely used in high-rise building structural systems, such as frame shear wall structures and simplified structures. In actual building structures, shear walls will have door openings and window openings due to lighting and building function needs. These openings will be considered in advance in the building structure design. Designers often take reinforcement measures such as hidden columns or hidden beams at weak parts of the openings to ensure the resistance of the shear walls.

[0003] However, in the renovation and reinforcement projects of existing buildings, the reinforcement and dimensions of the shear walls are already fixed. If openings need to be made in the shear walls due to the functional requirements of the owner, the bearing capacity of the shear walls in the original structure will be greatly reduced. Therefore, reinforcement measures should be taken after the openings in the shear walls to ensure the performance of the original structure. Therefore, how to reinforce the shear wall openings after the openings are made is a technical problem that needs to be solved urgently in the existing technology. Summary of the Invention

[0004] To achieve the above objectives, the present invention first proposes a post-opening shear wall opening wrapped steel-bonded reinforcement structure and construction method that ensures the reinforcement effect and the performance of the original structure.

[0005] The present invention relates to a post-opening shear wall opening wrapped type bonded steel reinforcement structure, comprising an inner support plate and an outer cover plate. A post-opening slot is provided in the middle of the shear wall, and the inner support plate matches the size and shape of the inner side wall of the slot. The inner support plate is arranged on the inner side wall of the slot, and the inner support plate and the shear wall are fixedly connected by a first bolt.

[0006] The outer cladding plate is a plate body with an opening in the middle that matches the size of the slot hole. An insertion plate arranged perpendicular to the outer cladding plate is fixed at the middle opening of the outer cladding plate and on each inner side edge. A slot that matches the size and position of the insertion plate is opened on at least one outer side of the inner support plate. The outer cladding plate is inserted into the slot of the inner support plate through the insertion plate, and the outer cladding plate and the shear wall are fixed by fixing parts. Angle plates matching the corner shape are provided at the corners where the inner support plates are connected. Inner lining plates are arranged on the inner support plates and between adjacent angle plates. The angle plates and the inner lining plates press the insertion plates on the outer cladding plate into the slots of the inner support plates, and the angle plates and the insertion plates arranged at the position of the angle plates are fixed to the inner support plates by second bolts, and the inner lining plates and the insertion plates arranged at the position of the inner lining plates are fixed to the inner support plates by third bolts.

[0007] In this embodiment, the inner support plate and the outer cladding plate are both made of steel plates.

[0008] In this embodiment, the slot is provided on the inner side wall of the inner support plate, the plug-in board matches the slot in size, and after the plug-in board is inserted into the slot, the upper surface of the plug-in board is flush with the outer surface of the inner side wall of the inner support plate.

[0009] In this embodiment, the fixing member is a fifth bolt, and the outer panel and the shear wall are fixedly connected by a plurality of fifth bolts, and the bolt bodies of the fifth bolts penetrate the outer panel and are fixed to the shear wall.

[0010] In this embodiment, the inner support plate is four independent steel plates whose sizes match the four inner side walls of the slot hole, or the inner support plate is an integral annular plate whose size and shape match the inner side wall of the slot hole.

[0011] In this embodiment, a filling layer is provided in the gap between the inner support plate and the shear wall.

[0012] In this embodiment, second slots are provided on the outer cladding plate near the four corners, and second reinforcing plates are fixedly connected on the inner side walls of the second slots at the four corners, and the shape of the second reinforcing plates matches the shape of the second slot corners; first slots are provided on the outer cladding plate near the left and right sides of the slot hole, and first reinforcing plates are fixedly connected on the inner side walls of the first slots at the four corners; the shape of the first reinforcing plate matches the shape of the first slot corners; grooves connected to the first slot are symmetrically provided on the outer side walls of the outer cladding plate on both sides near the first slot, and a pressure plate spanning the first slot is arranged between the two grooves on the outer cladding plate, and the pressure plate is fixedly connected to the outer cladding plate by a fourth bolt, and the bolt body of the fourth bolt penetrates the outer cladding plate and is fixed to the shear wall.

[0013] The present invention also includes a post-opening shear wall opening wrapping type steel bonding reinforcement construction method, which specifically includes the following steps:

[0014] a. According to the required hole size, a slot hole is excavated at the specified location on the shear wall. After the slot hole is excavated, a slotted bolt hole is then made at the specified location on the shear wall. Four inner support plates are respectively attached to the four sides of the inner wall of the slot hole. The inner support plates are then fixed to the inner wall of the slot hole with the first bolts. The diagonal parts of the inner support plates are then welded.

[0015] b. Install the outer cover plate between the shear wall and the inner support plate. During installation, insert the insert plate on the outer cover plate into the slot on the surface of the inner support plate, and then use the fifth bolt to penetrate and connect the outer cover plate to the shear wall;

[0016] c. Install the four angle plates at the four corners of the inner support plate in the slot, and then use the second bolt to fix the angle plates and the corresponding inserts on the inner support plate;

[0017] d. Install the inner lining plate on the inner support plate and between adjacent angle plates, and then use the third bolt to fix the inner lining plate and the insert plates at the corresponding positions of the inner lining plate to the inner support plate.

[0018] Compared with the prior art, the present invention has the following significant advantages:

[0019] 1. The present invention fixes the inner support plate inside the slot hole, strengthens the connection of the four corners of the adjacent inner support plates by means of angle plates, and then inserts the fixed side of the L-shaped outer panel into the slot of the inner support plate, so that the supporting side of the outer panel is covered on the shear wall outside the slot hole, and the outer panel is fixedly connected to the inner support plate, and then the fixed side of the outer panel is pressed tightly by the inner lining plate fixed to the inner support plate, so that the inner support plate and the outer panel are connected as a whole. Through such an arrangement, the inner support plate provides a preliminary support to the vertical and horizontal directions of the inside of the slot hole, and at the same time, the force exerted on the inner support plate is transmitted to the outer panel, thereby ensuring that the slot hole position is effectively supported and the performance of the original structure is ensured;

[0020] 2. A plurality of first slots and second slots are provided on the outer cladding plate. The setting of the first slots and the second slots reduces the weight of the outer cladding plate. At the same time, the reinforcing plates provided at the inner corners of the first slots and the second slots are used to offset the loss of bearing capacity caused by the slots on the outer cladding plate. At the same time, a pressure plate is fixed on the first slot along the force direction of the outer cladding plate, thereby improving the bearing capacity of the outer cladding plate, ensuring the supporting performance, and ensuring the reinforcement effect.
