Description

Technical Field

[0001] This invention relates to the field of damping wall technology in civil engineering structures, specifically to a high-performance sealed viscous damping wall. Background Technology

[0002] Damping walls for buildings are safety devices installed on buildings to mitigate earthquake damage. They are widely used in civil buildings, industrial buildings, and bridges. When an earthquake occurs, damping walls absorb and dissipate the impact energy of the earthquake on the building structure to the maximum extent, greatly mitigating the impact and damage of the earthquake on the building structure.

[0003] However, existing building damping walls still have many defects. For example, existing damping walls have poor sealing performance, silicone oil is easily contaminated, which affects product performance, and conventional open damping walls cannot be tilted during hoisting, making assembly inconvenient.

[0004] Therefore, a damper with good sealing performance is selected; however, during installation, the embedded part is prone to loosening between itself and the wall, increasing the risk of the ear plate falling off; at the same time, it is not convenient to replace it later.

[0005] Therefore, since it does not meet the existing requirements, we propose a high-performance sealed viscous damping wall. Summary of the Invention

[0006] Therefore, the present invention provides a high-performance sealed viscous damping wall to solve the above-mentioned problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] According to a first aspect of the present invention, a high-performance sealed viscous damping wall includes a viscous damper;

[0009] A steel frame symmetrically arranged at both ends of the viscous damper, with an ear plate fixedly connected to the outer side of each steel frame;

[0010] An embedded part installed on the wall has a set hole on the ear plate. The inner wall of the set hole is slidably connected to the outer wall of the embedded part and is fixed to the embedded part by a fixing cap through a thread.

[0011] A backlash-free ball joint is installed at the connection points between the viscous damper and the steel frame at both ends to achieve a hinged connection between the viscous damper and the steel frame;

[0012] The damping wall is adapted to multi-directional displacement transmission through a gapless ball joint and supports rotational or tilted installation.

[0013] Furthermore, a connection mechanism is provided between the embedded part and the wall; the connection mechanism includes: an installation hole opened on the wall.

[0014] Furthermore, the connecting mechanism also includes:

[0015] Pre-embedded fixing cylinders are fixed to the inner wall of the mounting holes in the wall;

[0016] A tapered sleeve is slidably connected to the inner wall of a pre-embedded fixing cylinder, and a pin is provided on its outer wall. A pin hole matching the pin is opened on the inner wall of the pre-embedded fixing cylinder.

[0017] A cylindrical support sleeve is slidably connected to the inner wall of a conical sleeve, and the inner wall of the sleeve is slidably connected to an embedded part.

[0018] The insert is fitted onto the outer wall of the embedded part and threadedly connected to the inner wall of the tapered sleeve.

[0019] Furthermore, the tapered sleeve includes:

[0020] Circular fixing plate one;

[0021] An annular connecting plate fixedly connected to the inner side of the annular fixing plate;

[0022] And elastic sheets arranged in a ring array are fixed to the end of the ring connecting plate away from the ring fixing plate; pins are arranged in an array on the outer wall of the elastic sheets.

[0023] Furthermore, a vertical guide groove is formed on the inner wall of the conical sleeve.

[0024] Furthermore, the cylindrical support sleeve has a fixed annular array of guide blocks on its outer wall, and the guide blocks are slidably engaged with the guide grooves.

[0025] Furthermore, the embedded part includes an embedded rod and a frustum-shaped block fixed to the end of the embedded rod.

[0026] Furthermore, the insert includes:

[0027] The pressure cylinder has a limiting groove on its inner wall that fits into the frustum-shaped block;

[0028] The upper pressure cylinder is fixedly connected to the top of the lower pressure cylinder, and its inner wall has a channel that fits with the outer wall of the buried rod.

[0029] The second annular fixing plate is fixedly connected to the top of the upper pressure cylinder.

[0030] Furthermore, the lower part of the inner wall of the pre-embedded fixing cylinder is a frustum-shaped surface, the bottom end of the elastic sheet is fixed with a connecting block, and the inner side of the connecting block is provided with an inclined surface; the end of the frustum-shaped block away from the embedded rod is fixed with a frustum-shaped abutment, and its outer wall fits with the inclined surface;

[0031] A mounting bracket is fixedly installed on the inner side of the ear plate;

[0032] A disc spring is provided between the outer side of the insert and the mounting bracket, and the disc spring is sleeved on the outer wall of the embedded rod.

[0033] Furthermore, under extrusion conditions, the frustum-shaped abutment pushes the connecting block radially through the inclined surface, forcing the pin to be deeply embedded in the pin hole, while the disc spring provides buffering and reset preload.

[0034] The present invention has the following advantages:

[0035] 1. This high-performance sealed viscous damping wall achieves universal hinge connection between the viscous damper and the steel frame through a gapless ball joint. It not only effectively transmits multi-directional seismic or wind-induced loads, but also eliminates bending moment stress concentration at the connection point, significantly improving adaptability to inter-story displacement and installation errors. The nonlinear damping force generated by the damping fluid flowing through the piston throttling orifice inside the viscous damper efficiently converts vibration mechanical energy into heat energy dissipation, greatly reducing structural acceleration and displacement response. Its thermal sprayed zinc and paint anti-corrosion layer ensure long-term service in harsh environments.

[0036] 2. This high-performance sealed viscous damping wall features a completely sealed structure, which, compared to conventional open viscous damping walls, avoids silicone oil contamination and better ensures product durability. The damping wall is easy to install on-site; it can be rotated or tilted according to actual site conditions. The steel frame side plates have connection holes for experimental platforms, allowing direct connection. After testing, the wall can be directly removed and used on-site, enabling non-destructive testing of the viscous damping wall. Multiple sets of viscous dampers are connected to the steel frame via gapless ball joints, exhibiting excellent synergistic performance.

[0037] 3. This high-performance sealed viscous damping wall has a connection mechanism that uses the initial locking of the elastic plate of the conical sleeve and the pin, the threaded lifting and fixing of the insert, and the adaptive radial locking triggered by the frustum-shaped stop block and the inclined surface under working load. This triple protection dynamically enhances the node's resistance to pull-out shear and completely eliminates loosening failure. The disc spring synchronously absorbs the impact energy and drives the reset. Combined with the positioning tolerance design of the embedded parts, a highly reliable and low-maintenance damping wall system is achieved. Attached Figure Description

[0051] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Example 1;

[0053] Reference Figures 1-12A high-performance sealed viscous damping wall includes a viscous damper 1 and steel frames 3 installed at both ends of the viscous damper 1. Each steel frame 3 has an ear plate 4 fixedly connected to its outer side. An embedded part 5 is provided on the wall body 7. A setting hole 671 is opened on the ear plate 4. The inner wall of the setting hole 671 is slidably connected to the outer wall of the embedded part 5. Then, the inner side of the fixing cap 68 is threadedly connected to the outer wall of the embedded part 5 to fix it.

[0054] The two ends of the viscous damper 1 are respectively provided with gapless ball joints 2 at the connection points with the steel frame 3; the viscous damper 1 and the steel frame 3 are hinged by the gapless ball joints 2;

[0055] In use: Two sets of gapless ball hinges 2 are symmetrically fixedly connected on the inner side of the two steel frames 3. A viscous damper 1 is installed between the two sets of gapless ball hinges 2. The viscous damper 1 is protected against corrosion by hot spray zinc and paint. The outer side of the steel frame 3 is connected to the ear plate 4. The ear plate 4 is fixed to the wall by embedded parts 5. The damping wall can be rotated and tilted according to the actual site conditions. Under the action of external loads such as earthquakes or wind loads, the building wall 7 drives the steel frame 3 to reciprocate. Since the inner side of the steel frame 3 is connected to the gapless ball hinges 2 and the viscous damper 1, the viscous damper 1 generates damping force inside, which converts the vibration energy of the input structure into heat energy and consumes it, so as to achieve the purpose of linkage energy consumption.

[0056] The piston rod 104 of the viscous damper 1 drives the piston 103 to reciprocate within the oil cylinder 101, consuming energy.

[0057] Specifically: the viscous damper 1 includes a hydraulic cylinder 101; a piston 103 is slidably connected to the inner wall of the hydraulic cylinder 101, and a piston rod 104 is fixedly connected to the middle of the piston 103; the hydraulic cylinder 101 is filled with damping fluid, and the two sides of the hydraulic cylinder 101 are sealed with end caps 102; an extension pipe 105 is provided at one end of the hydraulic cylinder 101, and the extension pipe 105 provides space for the movement of the piston rod 104;

[0058] The backlash-free ball joint 2 includes two connecting rods 201, which are fixedly installed at both ends of the viscous damper 1, that is, respectively installed at the output end of the piston rod 104 and the other end of the cylinder 101.

[0059] A ball 202 is fixedly connected to the end of the connecting rod 201 away from the viscous damper 1; a ball joint seat 203 is fixedly connected to the inner side of the steel frame 3; a connecting groove 204 is provided on the ball joint seat 203; the inner wall of the connecting groove 204 is rotatably connected to the outer wall of the ball 202.

[0060] Working principle: When the building experiences inter-story displacement due to earthquake or wind load, the embedded parts 5 fixed to the two side walls 7 drive the ear plates 4 and steel frame 3 to move relative to each other; this movement is transmitted to both ends of the viscous damper 1 through the gapless ball joint 2, forcing the piston rod 104 to reciprocate relative to the cylinder 101; when the piston 103 moves in the cylinder 101 filled with damping fluid, the damping fluid is forced to flow through the throttling orifice on the piston 103 (not shown in the diagram, a conventional design), generating a strong viscous damping force; this damping force is always opposite to the direction of the piston 103's movement speed, thereby effectively suppressing structural vibration and converting the input... Mechanical energy is converted into heat energy and dissipated; the design of the gapless ball joint 2 ensures smooth transmission of small rotations in any direction, avoiding bending moments and stress concentrations at the connection, and improving the damping wall's adaptability to installation errors and complex deformations; the viscous damper 1 has stable nonlinear damping characteristics, which can significantly reduce the acceleration and displacement response of the structure under earthquakes and wind vibrations; the gapless ball joint 2 ensures effective force transmission and device durability; thermal spraying zinc and paint anti-corrosion treatment ensure the long-term service performance of the viscous damper 1 in harsh environments; the installation method is flexible and can be rotated or tilted according to space requirements.

[0061] Example 2:

[0062] Basically the same as in Example 1, but further: referring to Figure 1-3 , Figure 10 A high-performance sealed viscous damping wall, wherein a telescopic sleeve 9 is provided between two steel frames 3 and sleeved on the outside of the viscous damper 1; the telescopic sleeve 9 includes a sleeve one 901 and a sleeve two 902 respectively installed on the two steel frames 3; the outer wall of the sleeve one 901 is slidably connected to the inner wall of the sleeve two 902.

[0063] The telescopic sleeve 9 is protected against corrosion by hot-dip galvanizing. The steel frame 3 has experimental connection holes, which can be directly connected to the experimental table. After the experiment is completed, it can be directly removed and used for on-site installation.

[0064] Working principle: The telescopic sleeve 9 extends or shortens accordingly with the reciprocating motion of the steel frame 3. Its main function is to form a relatively sealed protective space outside the viscous damper 1;

[0065] The telescopic sleeve 9 effectively prevents external dust, moisture, splashes, etc. from entering the viscous damper 1 and its connecting parts; especially inside the gapless ball joint 2, it significantly improves the sealing and protection level of the entire damping wall system, reduces maintenance requirements, and extends service life; the hot-dip galvanizing process further enhances its corrosion resistance; the experimental connection hole design on the steel frame 3 facilitates the mechanical performance testing and verification of the damping wall before leaving the factory or before installation. After the test is completed, it can be directly used for engineering installation without replacing parts, improving efficiency and reliability.

[0066] Example 3:

[0067] Basically the same as in Example 1, but further: referring to Figures 1-12 A high-performance sealed viscous damping wall, wherein an embedded part 5 is provided with a connection mechanism 6 between the embedded part 5 and the wall body 7; the connection mechanism 6 includes an installation hole 61 opened on the wall body 7; and a pre-embedded fixing cylinder 62 fixedly installed on the inner wall of the installation hole 61.

[0068] The inner wall of the pre-embedded fixing cylinder 62 is slidably connected to a conical sleeve 64; the outer wall of the conical sleeve 64 is fixedly provided with a pin 644; the inner wall of the pre-embedded fixing cylinder 62 is provided with a pin hole 63 corresponding to the pin 644.

[0069] The outer side of the ear plate 4 is fixedly connected to the mounting bracket 67; fixed holes 671 are provided at the four corners of the mounting bracket 67;

[0070] A cylindrical support sleeve 65 is slidably connected to the inner wall of the conical sleeve 64; an embedded part 5 is slidably connected to the inner wall of the cylindrical support sleeve 65; an insert 66 is sleeved on the outer wall of the embedded part 5; the upper outer wall of the insert 66 is threadedly connected to the inner wall of the conical sleeve 64, thereby fixing the embedded part 5.

[0071] The end of the embedded part 5 is threaded through the fixed hole 671 and connected to the inner wall of the fixing cap 68 to fix it.

[0072] Specifically: such as Figure 7 As shown: The conical sleeve 64 includes an annular fixing plate 641, an annular connecting plate 642 is fixedly connected to the inner side of the annular fixing plate 641, and elastic sheets 643 are arranged in annular array at the end of the annular connecting plate 642 away from the annular fixing plate 641. Pins 644 are arranged in an array on the outer wall of the elastic sheets 643. In the normal state, the end of the elastic sheet 643 away from the annular connecting plate 642 is curled inward. Vertical guide grooves 647 are opened on the inner wall of the conical sleeve 64.

[0073] The outer wall of the cylindrical support sleeve 65 is slidably connected to the inner wall of the conical sleeve 64, and a guide block 651 is also fixedly connected to its outer wall; multiple guide blocks 651 are distributed in a ring array on its outer wall; the number corresponds to the number of guide grooves 647.

[0074] like Figure 8 As shown: Embedded part 5 includes embedded rod 501, and a frustum-shaped block 502 is fixedly connected to the end of embedded rod 501;

[0075] like Figure 9As shown: The insert 66 includes a lower pressing cylinder 661, an upper pressing cylinder 662 fixedly connected to the lower pressing cylinder 661, and an annular fixing plate 663 fixedly connected to the upper pressing cylinder 662; the inner wall of the lower pressing cylinder 661 is provided with a limiting groove 664 that fits into the frustum-shaped block 502; the inner wall of the upper pressing cylinder 662 is provided with a channel 665; the inner wall fits into the outer wall of the embedded rod 501; the outer wall of the upper pressing cylinder 662 is threadedly connected to the inner wall of the annular connecting plate 642 of the conical sleeve 64;

[0076] In use: Insert the conical sleeve 64 into the pre-embedded fixing cylinder 62; the annular fixing plate 641 of the conical sleeve 64 is fixedly connected to the end of the pre-embedded fixing cylinder 62 by bolts; insert the cylindrical expanding sleeve 65 into the conical sleeve 64; at the same time, insert the guide block 651 of the cylindrical expanding sleeve 65 outward into the guide groove 647 on the inner wall of the conical sleeve 64, thereby expanding the conical sleeve 64, pushing the elastic plate 643 to open and driving the pin 644 to be inserted into the pin hole 63 to fix it.

[0077] Then, the embedded part 5 is inserted into the cylindrical expansion sleeve 65, the insert 66 is sleeved on the outside of the embedded part 5, the limiting groove 664 of the insert 66 is pressed against the frustum block 502, and the outer wall of the insert 66 is threaded to the inner wall of the conical sleeve 64; at the same time, the insert 66 is fixed to the wall 7 with bolts; thereby fixing the embedded part 5.

[0078] Working principle: During installation, the cylindrical expansion sleeve 65 is inserted, forcing the elastic plate 643 of the conical sleeve 64 to expand radially, causing the pin 644 to engage in the pin hole 63 of the pre-embedded fixing cylinder 62, thus achieving initial reliable positioning of the conical sleeve 64 within the pre-embedded fixing cylinder 62; subsequently, the embedded part 5 is inserted, and then the insert 66 is screwed in; the limiting groove 664 of the pressing cylinder 661 of the insert 66 engages the frustum-shaped block 502 of the embedded part 5, and the threaded connection between the insert 66 and the conical sleeve 64 generates a downward... The tension, on the one hand, pulls the embedded part 5 upward through the limiting groove 664 so that its end frustum block 502 is tightly attached to the lower pressure cylinder 661; on the other hand, the annular fixing plate 663 fixes the insert 66 itself to the surface of the wall 7, and finally the embedded part 5 is firmly clamped and fixed between the conical sleeve 64 and the insert 66; finally, the end of the embedded rod 501 of the embedded part 5 passes through the fixed hole 671 of the mounting bracket 67 of the ear plate 4 and is locked by the fixing cap 68, thus completing the connection between the damping wall and the wall 7.

[0079] Further: such as Figure 5 , Figure 6 The inner wall of the pre-embedded fixing cylinder 62 is provided with a frustum-shaped surface 621 to allow space for future use; a connecting block 645 is fixedly connected to the bottom end of the elastic sheet 643; the inner side of the connecting block 645 is provided with an inclined surface 646.

[0080] A frustum-shaped block 502 is fixedly connected to a frustum-shaped abutment 503 at one end away from the embedded rod 501; the outer wall of the frustum-shaped abutment 503 fits into the inclined surface 646.

[0081] Meanwhile, a disc spring 69 is provided between the outer side of the insert 66 and the mounting bracket 67; and the disc spring 69 is sleeved on the outer wall of the embedded rod 501.

[0082] During use; when the two walls 7 are vibrated, the viscous damper 1 will extend and retract; during compression; the ear plate 4 compresses the disc spring 69 through the mounting bracket 67, and at the same time provides a thrust to the embedded rod 501 in the direction of the interior of the wall 7; the embedded rod 501 drives the frustum block 503 to move through the frustum block 502, and the frustum block 503 pushes the connecting block 645 to move outward by engaging with the inclined surface 646 of the connecting block 645, and the connecting block 645 drives the elastic plate 643 to open outward, so that the pin 644 is inserted more tightly into the pin hole 63, making the installation more secure;

[0083] Working principle: When the damping wall is working, the two walls 7 undergo relative motion and compression, pushing the ear plate 4 and the mounting bracket 67 to move towards each other; the mounting bracket 67 compresses the disc spring 69 and pushes the embedded rod 501 of the embedded part 5 to move inward towards the inside of the pre-embedded fixing cylinder 62 [i.e., towards the inside of the wall 7]; the embedded rod 501 drives the frustum-shaped abutment 503 at its end to move synchronously; the conical surface of the frustum-shaped abutment 503 contacts the inclined surface 646 of the connecting block 645 and generates a wedging effect, forcing the connecting block 645 and the elastic plate 643 connected to it to expand further outward radially. The expansion of the elastic plate 643 causes the pin 644 on its outer wall to be embedded deeper and tighter into the pin hole 63 of the pre-embedded fixing cylinder 62, forming an adaptive locking mechanism; the disc spring 69 plays a role in buffering and providing continuous preload during this process;

[0084] The effects are as follows: Under external loads, especially pressure, the connecting mechanism 6 can automatically generate additional radial locking force, making the engagement between the pin 644 and the pin hole 63 more tight, significantly improving the pull-out and shear resistance of the connection node under dynamic loads, effectively preventing loosening and failure, and greatly enhancing the reliability and safety of the connection between the damping wall and the main structure; at the same time, the disc spring 69 can absorb some of the impact energy and help the embedded part 5 and the connecting mechanism 6 to reset after the load is released, reducing residual deformation; and through the cooperation of the conical sleeve 64, the cylindrical expansion sleeve 65, and the insert 66, the on-site installation steps are simplified, and there is a certain tolerance for the positioning accuracy of the embedded part; finally, the combination of the locking of the pin 644, the thread tightening and wedging effects provides multi-layered fixing protection.
