Description

Technical Field

[0001] The present invention relates to the technical field of energy dissipation and vibration reduction of building structures, and more particularly to a connecting wall suitable for a small-output plate-type damper. Background Art

[0002] A low-output plate damper is a device used for structural shock absorption and buffering. It mainly dissipates structural vibration energy through bending deformation or frictional sliding of metal plates, thereby reducing the vibration response of the structure. Its core feature is "low output", that is, the force it can withstand and transmit is relatively small, which is suitable for scenarios with low shock absorption requirements and small loads.

[0003] The utility model patent with patent application publication number CN220704820U discloses a wall-type damper installation structure, including an upper steel frame embedded in the upper pier, a lower steel frame embedded in the lower pier, and a damper located between the upper pier and the lower pier. Upper embedded plates and lower embedded plates are embedded in the upper pier and the lower pier, and the upper embedded plates and the lower embedded plates are respectively connected and fixed to the top and bottom ends of the damper; the upper steel frame includes multiple steel supports, and the outer sides of the multiple steel supports are provided with reinforcing rib rings for connection support.

[0004] However, in actual use, the load transmitted by the small-output plate damper is relatively small. If it is constructed using traditional connections such as heavy concrete walls and all-steel structure walls, it will lead to excessive strength of the connection structure, excessive weight, high cost, and mismatch with the damper output, thereby affecting the overall shock absorption effect and easily causing damage. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a connecting wall suitable for a small-output plate-type damper to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a connecting wall suitable for a small-output plate-type damper, comprising a damping layer, a lower wall assembly, an upper wall assembly, an upper beam, and a lower beam; flexible filling layers are fixedly provided on the side walls of the damping layer, the lower wall assembly, and the upper wall assembly; the bottom and top ends of the damping layer are fixedly connected to the lower wall assembly and the upper wall assembly, respectively;

[0007] One end of the lower wall assembly is fixedly connected to the lower beam body, and a beam embedded steel plate is fixed inside the lower beam body. Short positioning steel bars for positioning are welded on the beam embedded steel plate and the damping layer. The short positioning steel bars cooperate with the lower wall assembly and the upper wall assembly.

[0008] Preferably, the damping layer includes a composite buffer body and a damper lower steel plate and a damper upper steel plate located at two ends of the composite buffer body.

[0009] Preferably, the lower wall assembly includes a first masonry, a first side steel plate symmetrically arranged on both sides of the first masonry, a second masonry fixed to the top of the first masonry, and a first annular steel bar. The first masonry is fixedly connected to the embedded steel plate of the beam through a tie bar, and the second masonry is connected to the lower steel plate of the damper.

[0010] Preferably, both ends of the first side steel plate are welded to the beam embedded steel plate and the damper lower steel plate respectively.

[0011] Preferably, there are several first annular steel bars, which are evenly distributed along the height direction of the first masonry and the second masonry, and the binding ends of two adjacent first annular steel bars are in opposite directions.

[0012] Preferably, the upper wall assembly includes a third masonry, second side steel plates symmetrically arranged on both sides of the third masonry, and a fourth masonry built on the top of the third masonry;

[0013] The fourth masonry is provided with second annular steel bars evenly arranged along the height direction, and the second annular steel bars are fixedly connected to the second side steel plate;

[0014] The third masonry and one end of the second side steel plate are both fixedly connected to the damper upper steel plate.

[0015] Preferably, a top embedded part is fixedly connected inside the upper beam body, and the fourth masonry body and the second side steel plate are fixedly connected to the upper beam body through the top embedded part.

[0016] Technical effects and advantages of the present invention:

[0017] 1. The present invention avoids the risk of cracking caused by insufficient lateral stiffness and dispersed load transfer in pure masonry structures through the provision of composite buffers, flexible filling layers, lower wall components, upper wall components, and short positioning steel bars. It also solves the problems of inaccurate positioning of connection parts and large construction errors. Furthermore, the entire structure does not require conduit concrete, but is built by brickwork, saving costs and overall weight. It avoids the material waste and excessive deadweight problems of traditional heavy walls. Furthermore, the provision of multiple composite buffers enables the wall to effectively buffer and release forces at different angles through its own deformation, further extending the service life of the wall.

[0018] 2. In the present invention, the two ends of the first side steel plate respectively form a vertical rigid skeleton with the embedded steel plate of the beam and the steel plate under the damper, which directly bears part of the lateral force, avoids the masonry from cracking due to insufficient lateral rigidity, and at the same time can restrain the deformation of the masonry and improve the overall stability; the first annular steel bar can disperse the vertical force and avoid local stress concentration. At the same time, the adjacent binding ends are in opposite directions, and can evenly apply annular constraint force to prevent the steel bars from loosening or the masonry from being cracked. The two work together to make up for the defects of weak shear and bending resistance of the masonry, and enhance the structural safety and service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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] As attached Figure 1-5A connecting wall suitable for a small-output plate damper is shown, comprising a damping layer 1, a lower wall assembly 2, an upper wall assembly 3, an upper beam, and a lower beam, wherein reinforcing ribs are embedded in the upper and lower beams. Flexible filling layers are fixedly provided on the side walls of the damping layer 1, the lower wall assembly 2, and the upper wall assembly 3. The flexible filling layers are filled with flexible material. By filling the flexible material into the gaps and side walls of the damping layer 1, the lower wall assembly 2, and the upper wall assembly 3, when the entire wall is subjected to force, the flexible filling layer can also partially buffer the force received, thereby reducing the burden on the damping layer 1, improving the buffering effect of the wall, and increasing its service life.

[0027] The bottom and top ends of the damping layer 1 are fixedly connected to the lower wall assembly 2 and the upper wall assembly 3 respectively; one end of the lower wall assembly 2 is fixedly connected to the lower beam body, and a beam embedded steel plate 4 is fixed inside the lower beam body. Short positioning steel bars for positioning are welded to the beam embedded steel plate 4 and the damping layer 1, and the short positioning steel bars cooperate with the lower wall assembly 2 and the upper wall assembly 3.

[0028] Specifically, the damping layer 1 includes a plurality of composite buffer bodies 11 and a damper lower steel plate 12 and a damper upper steel plate 13 located at both ends of the plurality of composite buffer bodies 11. When the structure is subjected to vibration or impact loads, the composite buffer body 11 absorbs and consumes energy through its own deformation, thereby reducing the vibration response of the structure, playing the role of shock absorption and seismic isolation, and protecting the main structure from damage caused by excessive loads. In addition, the arrangement of multiple composite buffer bodies 11 enables the wall to effectively buffer and release forces at different angles through its own deformation, further increasing the service life of the wall.

[0029] Specifically, the lower wall assembly 2 includes a first masonry 21, a first side steel plate 22 symmetrically arranged on both sides of the first masonry 21, a second masonry 23 fixed to the top of the first masonry 21, and a first annular steel bar 24. The first masonry 21 is fixedly connected to the beam embedded steel plate 4 through tie bars, and the second masonry 23 is connected to the damper lower steel plate 12. The first masonry 21 is the lower foundation masonry, which is fixed to the beam embedded steel plate 4 through tie bars, bears the upper load and transmits it to the beam body; the first side steel plates 22 are symmetrically arranged on both sides thereof to enhance lateral stability, assist in dispersing the load and serve as a construction positioning reference; the second masonry 23 is built on the top of the first masonry 21 and is directly connected to the damper lower steel plate 12 to transfer the load; the first annular steel bar 24 is distributed along the height of the masonry and is fixed to the first side steel plate 22, combining the masonry and the steel plate into a whole.

[0030] Specifically, the upper wall assembly 3 includes a third masonry 31, second side steel plates 32 symmetrically arranged on both sides of the third masonry 31, and a fourth masonry 33 built on top of the third masonry 31. Second annular steel bars 34 are evenly arranged inside the fourth masonry 33 along the height direction, and the second annular steel bars 34 are fixedly connected to the second side steel plates 32. One end of the third masonry 31 and the second side steel plates 32 are welded to the damper upper steel plate 13. A top embedded part 35 is fixedly connected to the upper beam body. The fourth masonry 33 and one end of the second side steel plate 32 are fixedly connected to the upper beam body through the top embedded part 35, and can be fastened by bolts or welding. The first masonry 21, the second masonry 23, the third masonry 31, and the fourth masonry 33 are all constructed by stacking bricks. Compared with a single concrete pouring, the overall construction is simpler and more convenient, with lower construction costs and faster construction time, thus saving time and cost.

[0031] The short positioning steel bars on the lower steel plate 12 of the damper will correspond to the preset position at the top of the first masonry 21 or the welding mark of the first side steel plate 22. The second masonry 23 can be directly built along the steel bar contour, or aligned with the welding position of the first side steel plate 22 to ensure the precise connection between the masonry and the side steel plate and the lower steel plate to avoid misalignment. Similarly, the short positioning steel bars on the upper steel plate 13 of the damper correspond to the installation positions of the upper masonry and the side steel plate to guide the docking of the upper structure and the damper to ensure the alignment of the upper and lower force transmission paths.

[0032] After the fourth masonry 33 is subjected to force, the fourth masonry 33 transmits the force downward to the third masonry 31, and the second side steel plates 32 on both sides are subjected to force synchronously. The second annular steel bars 34 in the fourth masonry 33 pull the steel plates on both sides to transmit the force more evenly downward. The force is then transmitted to the upper steel plate 13 of the damper. After the composite buffer body 11 absorbs part of the energy, the remaining force is transmitted to the second masonry 23 of the lower wall assembly 2 through the lower steel plate 12 of the damper. After the second masonry 23 is subjected to force, it transmits the force to the first masonry 21 below. The first side steel plates 22 on both sides share part of the force. The first annular steel bars 24 tighten the first masonry 21 and the second masonry 23 to ensure that the force is transmitted downward smoothly. Finally, the first masonry 21 transmits all the force to the beam embedded steel plate 4 through the tie bars, and then the force is dispersed by the lower beam body.

[0033] It is worth noting that by setting the lower wall component 2, the upper wall component 3 and the short positioning steel bars, the risk of cracking caused by insufficient lateral stiffness of the pure masonry structure and dispersed load transfer is avoided, and the problems of inaccurate positioning of the connection parts and large construction errors are solved. At the same time, through the coordinated force of the masonry and the steel plate, the load requirements of the small-output damper are adapted, avoiding the material waste and excessive self-weight problems of traditional heavy walls.

[0034] The ends of the first side steel plate 22 are welded to the beam embedded steel plate 4 and the damper lower steel plate 12. There are a plurality of first annular steel bars 24, which are evenly distributed along the height of the first masonry 21 and the second masonry 23, and the binding ends of two adjacent first annular steel bars 24 are in opposite directions.

[0035] It is worth noting that the two ends of the first side steel plate 22 form a vertical rigid skeleton with the beam embedded steel plate 4 and the damper lower steel plate 12 respectively, which directly bears part of the lateral force to avoid the masonry from cracking due to insufficient lateral stiffness. At the same time, it can also restrain the deformation of the masonry and improve the overall stability; the first annular steel bar 24 can disperse the vertical force to avoid local stress concentration. At the same time, the adjacent binding ends are in opposite directions and can evenly apply annular constraint force to prevent the steel bars from loosening or the masonry from being cracked. The two work together to make up for the defects of the masonry's weak shear and bending resistance, and enhance the structural safety and service life.
