Description

Technical Field

[0001] The utility model relates to the technical field of shear wall connection, in particular to a vertical connection structure of a prefabricated shear wall. Background Art

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are the primary walls in buildings or structures that bear horizontal and vertical loads (gravity) caused by wind or earthquakes, preventing shear damage. They are generally made of reinforced concrete and are divided into two types: plane shear walls and cylindrical shear walls. Plane shear walls are used in reinforced concrete frame structures, slab-type structures, and beamless floor systems, while cylindrical shear walls are used in high-rise buildings, tall structures, and suspended structures. They are surrounded by partition walls for elevator rooms, stairwells, equipment, and auxiliary rooms. The cylindrical walls are all cast-in-place reinforced concrete walls. Their stiffness and strength are greater than those of plane shear walls, and they can withstand greater horizontal loads.

[0003] However, the existing vertical connection structures of some precast shear walls fail to fully consider various potential loads and stress conditions during design or construction, resulting in insufficient load-bearing capacity in practical applications. The connectors themselves are insufficiently strong to support the expected loads, and the connection method can lead to stress concentration or uneven distribution, thereby reducing the stability of the overall structure. To address these shortcomings, a vertical connection structure for precast shear walls is proposed to address these issues. Utility Model Content

[0004] In order to make up for the above deficiencies, the present invention provides a vertical connection structure of a prefabricated shear wall, aiming to improve the problem of insufficient bearing capacity and instability of the vertical connection structure of some prefabricated shear walls in the prior art after the connection is completed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The vertical connection structure of a prefabricated shear wall comprises an upper shear wall and a lower shear wall, wherein the upper shear wall is provided with a plurality of bolt holes 1, the lower shear wall is provided with a plurality of bolt holes 2, the bottom of the upper shear wall is fixedly connected to a steel plate 1, the steel plate 1 and the interior of the lower shear wall are both fixedly connected to a plurality of reinforcing ribs 1, the top of the lower shear wall is fixedly connected to a steel plate 2, the steel plate 2 is fixedly connected to the interior of the upper shear wall with a plurality of reinforcing ribs 2, the upper shear wall and the lower shear wall are both threadedly connected to a plurality of fastening bolts, the steel plate 1 and the steel plate 2 are both provided with a plurality of bolt holes 3, the steel plate 1 and the steel plate 2 are provided with a plurality of docking holes, the steel plate 1 and the steel plate 2 are internally threadedly connected to a plurality of reinforcing bolts, and a sealing component for waterproofing is provided on the adjacent side of the upper shear wall and the lower shear wall;

[0007] As a further description of the above technical solution:

[0008] The sealing assembly includes a sealing frame, the upper and lower sides of which are respectively fixedly connected to the adjacent sides of the upper shear wall and the lower shear wall, and the left and right sides of the sealing frame are both provided with a pouring port;

[0009] As a further description of the above technical solution:

[0010] The outer portion of the first steel plate is slidably connected to the inner portion of the lower shear wall, and the outer portion of the second steel plate is slidably connected to the inner portion of the upper shear wall;

[0011] As a further description of the above technical solution:

[0012] The outer portions of the first and second reinforcing ribs are both slidably connected to the interior of the docking hole, and the outer portion of the fastening bolt is threadedly connected to the interior of the third bolt hole;

[0014] The external threads of the reinforcing bolts are connected to the inside of the second steel plate and the first steel plate, and the external threads of the reinforcing bolts are connected to the inside of the sealing frame.

[0015] The utility model has the following beneficial effects:

[0016] 1. In this utility model, by installing steel plates 1 and 2 between the upper and lower shear walls and securely connecting multiple reinforcing ribs 1 and 2 within these steel plates, a secure connection between the shear walls is achieved. During the connection process, the reinforcing ribs slide into the docking holes of the opposing steel plates, increasing the contact area and dispersing stress, thereby significantly enhancing the overall stability of the structure. The use of fastening bolts and reinforcement bolts further ensures a tight connection between the upper and lower shear walls. This makes the connection between the upper and lower shear walls more stable and reliable, capable of withstanding heavy loads and external forces.

[0017] 2. In this utility model, the interior of the sealing frame is filled through the pouring port, ensuring the tightness of the joint between the upper and lower shear walls, effectively preventing moisture penetration and improving the waterproof performance of the structure. This not only protects the interior of the shear wall from moisture, extending the service life of the structure, but also helps maintain a dry environment inside the building, avoiding problems such as mold and corrosion caused by moisture intrusion.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 3The present invention provides an embodiment of a vertical connection structure of a prefabricated shear wall, comprising an upper shear wall 1 and a lower shear wall 2. The upper shear wall 1 is butted against the lower shear wall 2 to form the entire shear wall. A plurality of bolt holes 3 are provided inside the upper shear wall 1, and a plurality of bolt holes 4 are provided inside the lower shear wall 2. A steel plate 5 is fixedly connected to the bottom of the upper shear wall 1. During the butting process, the reinforcing rib 6 inside the upper shear wall 1 is fixed to the inside of the steel plate 5 by welding. The top of the reinforcing rib 6 inside the lower shear wall 2 slides into the bottom side of the butt hole 10 in the steel plate 5 and is then fixed with bolts, thereby enhancing the connection stability of the shear wall. The exterior of steel plate 1 (5) is slidably connected to the interior of lower shear wall 2. Multiple reinforcing ribs (6) are fixedly connected to the interior of both steel plate 1 (5) and lower shear wall 2. The exterior of reinforcing ribs (6) inside upper shear wall 1 is welded to the interior of steel plate 1 (5). The top of lower shear wall 2 is fixedly connected to steel plate 2 (7). The exterior of steel plate 2 (7) is slidably connected to the interior of upper shear wall 1. During the docking process, reinforcing ribs (14) inside lower shear wall 2 are welded to the interior of steel plate 2 (7). The bottom of reinforcing ribs (14) inside upper shear wall 1 slides into the interior bottom side of docking hole 10 in steel plate 2 (7), and is then secured with bolts, thereby enhancing the stability of the shear wall connection. Multiple reinforcing ribs (14) are fixedly connected to the interior of steel plate 2 (7). The exterior of reinforcing ribs (14) inside lower shear wall 2 is welded to the interior of steel plate 2 (7). The bottom of reinforcing ribs (14) inside upper shear wall 1 slides into docking hole 10 inside steel plate 1 (5). The outer portions of the reinforcing rib 1 6 and the reinforcing rib 2 14 are both slidably connected to the inner portion of the docking hole 10;

[0027] Reference Figures 3 to 5 The upper shear wall 1 and the lower shear wall 2 are both internally threaded with multiple fastening bolts 8. Bolt hole 1 3 is used for threaded connection with fastening bolts 8, and bolt hole 2 4 is used for threaded connection with fastening bolts 8. Multiple bolt holes 3 9 are provided inside both steel plate 1 5 and steel plate 2 7. The external threads of fastening bolts 8 are connected to the internal threads of bolt holes 3 9. Fastening bolts 8 fasten the upper shear wall 1 to steel plate 1 5 and the lower shear wall 2 to steel plate 2 7 from the front and back sides, respectively. Multiple docking holes 10 are provided inside steel plate 1 5 and steel plate 2 7. Docking holes 10 are used to slide reinforcement ribs 1 6 and reinforcement ribs 2 14 into the docking holes, thereby enhancing the stability of the shear wall connection. Multiple reinforcement bolts 11 are also threaded inside steel plate 1 5 and steel plate 2 7. Reinforcement bolts 11 are important components for secondary connection at the middle of the docking point between the upper shear wall 1 and the lower shear wall 2, making the connection more stable. The external threads of the reinforcing bolt 11 are connected to the inside of the steel plate 2 7 and the steel plate 1 5;

[0028] Reference Figure 1 、 Figure 2 and Figure 4A sealing component for waterproofing is provided on the adjacent side of the upper shear wall 1 and the lower shear wall 2.

The external thread of the reinforcing bolt 11 is connected to the inside of the sealing frame 12. A pouring port 13 is provided on both sides of the sealing frame 12. The interior of the sealing frame 12 is filled through the pouring port 13, so that the joint between the upper shear wall 1 and the lower shear wall 2 can be effectively sealed.

[0029] Working principle: When the upper shear wall 1 and the lower shear wall 2 need to be docked, the steel plate 15 at the bottom of the upper shear wall 1 can be aligned to the inside of the lower shear wall 2, and at the same time, the top of the reinforcing rib 16 inside the lower shear wall 2 can be aligned to the docking hole 10 inside the steel plate 15, and the bottom of the reinforcing rib 2 14 inside the upper shear wall 1 can be aligned to the docking hole 10 inside the steel plate 2 7. Then, the upper shear wall 1 can be placed downward, so that the reinforcing rib 1 6 and the reinforcing rib 2 14 can slide into the inside of the docking hole 10, and the steel plate 15 can enter the inner part of the lower shear wall 2. The steel plate 2 7 enters the interior of the upper shear wall 1, and then the upper shear wall 1 and the steel plate 1 5 as well as the lower shear wall 2 and the steel plate 2 7 can be fastened together from the front and rear sides respectively by the fastening bolts 8. Then, a secondary connection can be made in the middle of the joint between the upper shear wall 1 and the lower shear wall 2 by the reinforcing bolts 11, so that the connection can be made more stable. After the reinforcing bolts 11 and the fastening bolts 8 are connected, the interior of the sealing frame 12 can be filled through the pouring port 13, so that the joint between the upper shear wall 1 and the lower shear wall 2 can be effectively sealed.
