Description

Technical Field

[0001] The invention relates to the technical field of civil engineering structure damping walls, and in particular to a high-performance sealed viscous damping wall. Background Art

[0002] A building damping wall is a safety device installed on a building to reduce earthquake damage. It is widely used in civil buildings, industrial buildings, bridges, etc. When an earthquake occurs, the damping wall absorbs and consumes the impact energy of the earthquake on the building structure to the maximum extent, greatly alleviating the impact and damage of the earthquake on the building structure.

[0003] However, existing building damping walls still have many defects, such as poor sealing performance of existing damping walls, easy contamination of silicone oil, which affects product performance, and conventional open damping walls cannot be tilted during hoisting, making assembly inconvenient. For this purpose, a damper with good sealing performance is selected; however, during installation, the embedded parts are prone to loosening between the wall, increasing the risk of the ear plate falling off and making it inconvenient to replace it later. Therefore, the existing needs are not met, and we propose a high-performance sealed viscous damping wall. Summary of the Invention

[0004] To this end, the present invention provides a high-performance sealed viscous damping wall to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: According to a first aspect of the present invention, a high-performance sealed viscous damping wall includes a viscous damper; Steel frames are symmetrically arranged at both ends of the viscous damper, and the outer sides of each steel frame are fixedly connected with ear plates; Embedded parts are provided on the wall, wherein the ear plate has a set hole, the inner wall of the top hole is slidably connected to the outer wall of the embedded part, and is fixed to the embedded part by a fixing cap and a thread; The gapless ball joint is set at the connection between the two ends of the viscous damper and the steel frame to realize the hinge connection between the viscous damper and the steel frame; The damping wall adapts to multi-directional displacement transmission through a gapless spherical joint and supports rotational or tilting installation.

[0006] Furthermore, a connection mechanism is provided between the embedded part and the wall; the connection mechanism includes: a mounting hole opened on the wall.

[0007] Furthermore, the connecting mechanism further comprises: The embedded fixing tube is fixed to the inner wall of the mounting hole of the wall; The conical sleeve is slidably connected to the inner wall of the embedded fixing cylinder, and a pin is provided on the outer wall of the conical sleeve. The inner wall of the embedded fixing cylinder is provided with a pin hole matching the pin; The cylindrical expansion sleeve is slidably connected to the inner wall of the conical sleeve, and the inner wall thereof is slidably connected to the embedded part; The insert sleeve is sleeved on the outer wall of the embedded part and is threadedly connected with the inner wall of the tapered sleeve.

[0008] Furthermore, the tapered sleeve comprises: annular fixing plate 1; an annular connecting plate fixedly connected to an inner side of the annular fixing plate; And elastic sheets distributed in an annular array are fixed to one end of the annular connecting plate away from the annular fixing plate; pins are arranged in an array on the outer wall of the elastic sheets.

[0009] Furthermore, a vertical guide groove is provided on the inner wall of the conical sleeve.

[0010] Furthermore, the outer wall of the cylindrical expansion sleeve is fixed with an annular array of guide blocks, and the guide blocks are slidably engaged with the guide grooves.

[0011] Furthermore, the embedded part includes an embedded rod and a frustum-shaped block fixed to the end of the embedded rod.

[0012] Furthermore, the insert comprises: The lower pressing cylinder has an inner wall provided with a limiting groove which fits the truncated cone block; The upper pressure cylinder is fixedly connected to the top of the lower pressure cylinder, and a channel is provided on its inner wall to fit the outer wall of the buried rod; The second annular fixing plate is fixedly connected to the top of the upper pressure cylinder.

[0013] Furthermore, the lower part of the inner wall of the embedded fixing cylinder is a truncated cone-shaped surface, the bottom end of the elastic sheet is fixed to the connecting block, and the inner side of the connecting block is provided with an inclined surface; the end of the truncated cone-shaped block away from the embedded rod is fixed to a truncated cone-shaped block, the outer wall of which is in line with the inclined surface; A mounting bracket is fixedly provided on the inner side of the ear plate; A disc spring is arranged between the outer side of the inserting tube and the mounting frame, and the disc spring is sleeved on the outer wall of the buried rod.

[0014] Furthermore, under extrusion conditions, the truncated cone-shaped stop block pushes the connecting block to expand 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 force.

[0015] The present invention has the following advantages: 1. This high-performance sealed viscous damping wall uses a gapless spherical joint to achieve a universal articulation between the viscous damper and the steel frame. This 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 orifice in the viscous damper efficiently converts vibration mechanical energy into heat energy dissipation, significantly reducing the acceleration and displacement response of the structure. The thermally sprayed zinc and paint anti-corrosion layer ensure long-term service in harsh environments. 2. This is a high-performance sealed viscous damping wall with a completely sealed structure. Compared with conventional open viscous damping walls, it avoids silicone oil contamination and better ensures product durability. The damping wall is easy to install on site and can be rotated and tilted according to actual site conditions. The steel frame side panels have test bench connection holes that can be directly connected to the test bench. After the experiment is completed, it can be directly removed and used on the project site, realizing non-destructive testing of the viscous damping wall. Multiple groups of viscous dampers are connected to the steel frame through gapless ball joints, which have good collaborative working performance. 3. This is a high-performance sealed viscous damping wall. The connection mechanism is achieved through the initial locking of the elastic sheet and pin of the tapered sleeve, the threaded pull-up fixation of the insert, and the adaptive radial locking triggered by the conical block and the inclined surface under the working load. The triple guarantee dynamically enhances the node's anti-shear ability and completely eliminates loosening and failure. The disc spring simultaneously absorbs impact energy and drives reset. Combined with the embedded parts positioning tolerance design, a highly reliable and low-maintenance damping wall system is realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0019] Embodiment 1; Reference Figures 1-12 A high-performance sealed viscous damping wall comprises a viscous damper 1, steel frames 3 mounted at both ends of the viscous damper 1, and lug plates 4 fixedly connected to the outer sides of each steel frame 3; an embedded part 5 is provided on the wall 7; a setting hole 671 is formed in the lug plate 4; the inner wall of the setting hole 671 is slidably connected to the outer wall of the embedded part 5; and the inner side of a fixing cap 68 is then threadedly connected to the outer wall of the embedded part 5 to secure it. A gapless spherical joint 2 is provided at the connection between the two ends of the viscous damper 1 and the steel frame 3; the viscous damper 1 and the steel frame 3 are hingedly connected by the gapless spherical joint 2; During use: two sets of gapless spherical joints 2 are symmetrically fixedly connected on the inner sides of the steel frames 3 on both sides. A viscous damper 1 is installed between the two sets of gapless spherical joints 2. The viscous damper 1 is anti-corrosive using hot-sprayed zinc and painted. The outer side of the steel frame 3 is connected to the ear plate 4, and the ear plate 4 is fixed to the wall through embedded parts 5. The damping wall is rotated and tilted according to the actual situation on site. Under the action of external loads such as earthquakes or wind loads, the wall 7 of the building drives the steel frame 3 to reciprocate. Since the inner side of the steel frame 3 is connected to the gapless spherical joint 2 and the viscous damper 1, a damping force is generated inside the viscous damper 1, which converts the vibration energy of the input structure into heat energy and consumes it, achieving the purpose of realizing linked energy consumption. The piston rod 104 of the viscous damper 1 drives the piston 103 to reciprocate in the cylinder 101 to consume energy; Specifically, the viscous damper 1 includes a cylinder 101; a piston 103 is slidably connected to the inner wall of the cylinder 101, and a piston rod 104 is fixedly connected to the middle of the piston 103; the interior of the cylinder 101 is filled with damping fluid, and the two sides of the cylinder 101 are sealed with a head 102. An extension tube 105 is provided at one end of the cylinder 101 to provide a movable space for the movement of the piston rod 104; The clearance-free spherical joint 2 includes two connecting rods 201, which are fixedly mounted at both ends of the viscous damper 1, that is, mounted at the output end of the piston rod 104 and the other end of the oil cylinder 101, respectively. The end of the connecting rod 201 away from the viscous damper 1 is fixedly connected to the ball 202; the inner side of the steel frame 3 is fixedly connected to the ball joint seat 203; the ball joint seat 203 is provided with a connecting groove 204; the inner wall of the connecting groove 204 is rotatably connected to the outer wall of the ball 202; Working principle: When the building undergoes inter-story displacement due to earthquake or wind load, the embedded parts 5 fixed on the walls 7 on both sides drive the ear plates 4 and the steel frame 3 to produce relative movement; this movement is transmitted to the two 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 throttle hole on the piston 103 (not shown in the figure), which is a conventional design, generating a strong viscous damping force; this damping force is always in the opposite direction to the movement speed of the piston 103, thereby effectively suppressing the vibration of the structure and converting the input Mechanical energy is converted into heat energy and dissipated; the design of the gapless ball joint 2 ensures that small rotations in any direction can be transmitted smoothly, avoiding bending moments and stress concentration at the connection points, and improving the adaptability of the damping wall 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 the effective transmission of force and the durability of the device; hot-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.

[0020] Example 2: The same as the first embodiment, furthermore: refer to Figure 1-3 、 Figure 10 A high-performance sealed viscous damping wall is provided with a telescopic sleeve 9 between two steel frames 3 and sleeved on the outside of the viscous damper 1; the telescopic sleeve 9 includes a sleeve 1 901 and a sleeve 2 902 respectively mounted on the two steel frames 3; the outer wall of the sleeve 1 901 is slidably connected to the inner wall of the sleeve 2 902; The telescopic sleeve 9 is anti-corrosive by hot-dip galvanizing process. The steel frame 3 is provided with an experimental connection hole, which can be directly connected to the experimental table. After the experiment is completed, it can be directly disassembled for on-site installation. Working principle: The telescopic sleeve 9 extends or contracts accordingly with the reciprocating motion of the steel frame 3. Its main function is to form a relatively closed protective space outside the viscous damper 1; The telescopic sleeve 9 can effectively prevent external dust, moisture, splashing objects, etc. from entering the viscous damper 1 and its connecting parts; especially the inside of the gapless ball joint 2, which significantly improves the sealing and protection level of the entire damping wall system, reduces maintenance requirements and extends its 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, thereby improving efficiency and reliability.

[0021] Example 3: The same as the first embodiment, furthermore: refer to Figures 1-12 A high-performance sealed viscous damping wall, wherein a connecting mechanism 6 is provided between an embedded part 5 and a wall body 7; the connecting mechanism 6 comprises a mounting hole 61 formed on the wall body 7; and a pre-buried fixing cylinder 62 fixedly mounted on the inner wall of the mounting hole 61; The inner wall of the embedded fixing cylinder 62 is slidably connected to a tapered sleeve 64; the outer wall of the tapered sleeve 64 is fixed with a pin 644; the inner wall of the embedded fixing cylinder 62 is provided with a pin hole 63 corresponding to the pin 644; The outer side of the ear plate 4 is fixedly connected to the mounting bracket 67; the four corners of the mounting bracket 67 are each provided with a fixing hole 671; The inner wall of the conical sleeve 64 is slidably connected to a cylindrical expansion sleeve 65; the inner wall of the cylindrical expansion sleeve 65 is slidably connected to the embedded part 5; the outer wall of the embedded part 5 is provided with an insert sleeve 66; the upper outer wall of the insert sleeve 66 is threadedly connected to the inner wall of the conical sleeve 64, thereby fixing the embedded part 5; The end of the embedded part 5 is passed through the fixed hole 671 and threadedly connected to the inner wall of the fixing cap 68 to fix it.

[0022] Specific: such as Figure 7As shown, the conical sleeve 64 includes an annular fixing plate 641, an annular connecting plate 642 fixedly connected to the inner side of the annular fixing plate 641, and elastic sheets 643 are distributed in an annular array on the end of the annular connecting plate 642 away from the annular fixing plate 641. Pins 644 are distributed in an array on the outer wall of the elastic sheet 643. Under normal conditions, the end of the elastic sheet 643 away from the annular connecting plate 642 is curled inward. The inner wall of the conical sleeve 64 is provided with a vertical guide groove 647. The outer wall of the cylindrical expansion sleeve 65 is slidably connected to the inner wall of the conical sleeve 64, and a guide block 651 is fixedly connected to the outer wall thereof; a plurality of guide blocks 651 are distributed in an annular array on the outer wall thereof; the number thereof corresponds to the number of guide grooves 647; like Figure 8 As shown: the embedded part 5 includes an embedded rod 501, and the end of the embedded rod 501 is fixedly connected to a truncated cone-shaped block 502; like Figure 9 As shown: the insert cylinder 66 includes a lower pressure cylinder 661, an upper pressure cylinder 662 fixedly connected to the lower pressure cylinder 661, and an annular fixing plate 663 fixedly connected to the upper pressure cylinder 662; the inner wall of the lower pressure cylinder 661 is provided with a limiting groove 664 that fits with the truncated cone block 502; the inner wall of the upper pressure cylinder 662 is provided with a channel 665; the inner wall fits with the outer wall of the buried rod 501; the outer wall of the upper pressure cylinder 662 is threadedly connected to the inner wall of the annular connecting plate 642 of the conical sleeve 64; During use: insert the conical sleeve 64 into the embedded fixing cylinder 62; the annular fixing plate 641 of the conical sleeve 64 is fixedly connected to the end of the embedded fixing cylinder 62 by bolts; insert the cylindrical expansion sleeve 65 into the conical sleeve 64; at the same time, insert the guide block 651 of the cylindrical expansion sleeve 65 into the guide groove 647 on the inner wall of the conical sleeve 64, thereby expanding the conical sleeve 64, pushing the elastic sheet 643 to open and driving the pin 644 to be inserted into the pin hole 63 to fix it; Then, insert the embedded part 5 into the cylindrical expansion sleeve 65, sleeve the insert 66 onto the outside of the embedded part 5, press the limiting groove 664 of the insert 66 against the truncated cone block 502, and screw the outer wall of the insert 66 to the inner wall of the conical sleeve 64; at the same time, fix the insert 66 to the wall 7 with bolts; thus, the embedded part 5 is fixed; Working principle: During installation, the elastic piece 643 of the conical sleeve 64 is forced to expand radially by inserting the cylindrical expansion sleeve 65, so that the pin 644 is stuck in the pin hole 63 of the embedded fixing cylinder 62, and the conical sleeve 64 is initially and reliably positioned in the embedded fixing cylinder 62; then the embedded part 5 is inserted, and the inserting cylinder 66 is screwed in; the limiting groove 664 of the downward pressing cylinder 661 of the inserting cylinder 66 clamps the truncated cone block 502 of the embedded part 5, and the threaded connection between the inserting cylinder 66 and the conical sleeve 64 produces a downward The tensioning force, on the one hand, pulls the embedded part 5 upward by limiting the groove 664 so that the conical block 502 at its end is close to the lower pressure cylinder 661, and on the other hand, fixes the insert cylinder 66 itself to the surface of the wall 7 through the annular fixing plate 663, and finally firmly clamps the embedded part 5 between the conical sleeve 64 and the insert cylinder 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 to complete the connection between the damping wall and the wall 7.

[0023] Further: Figure 5 、 Figure 6 The inner wall of the embedded fixed cylinder 62 is provided below the truncated cone-shaped surface 621; space is reserved; the bottom end of the elastic sheet 643 is fixedly connected to the connecting block 645; the inner side of the connecting block 645 is provided with a slope 646; The end of the truncated cone block 502 away from the buried rod 501 is fixedly connected to the truncated cone block 503; the outer wall of the truncated cone block 503 is in line with the inclined surface 646; At the same time, 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 buried rod 501; When in use, when the two walls 7 are subjected to vibration, the viscous damper 1 will be driven to expand and contract; when squeezed, the ear plate 4 squeezes the disc spring 69 through the mounting bracket 67, and at the same time provides a thrust to the buried rod 501 toward the inside of the wall 7; the buried rod 501 drives the truncated cone-shaped block 503 to move through the truncated cone-shaped block 502, and the truncated cone-shaped block 503 pushes the connecting block 645 to move outward by fitting with the inclined surface 646 of the connecting block 645, and the connecting block 645 drives the elastic sheet 643 to open outward, so that the pin 644 is more tightly inserted into the pin hole 63, making the installation more secure; Working principle: When the damping wall is working, the walls 7 on both sides undergo relative motion and extrusion, pushing the ear plate 4 and the mounting bracket 67 to move toward each other; the mounting bracket 67 compresses the disc spring 69 and pushes the embedded rod 501 of the embedded part 5 to move toward the inside of the embedded fixing tube 62 [i.e., the inside of the wall 7]; the embedded rod 501 drives the frustum-shaped stop block 503 at its end to move synchronously; the conical surface of the frustum-shaped stop block 503 contacts the inclined surface 646 of the connecting block 645 and produces a wedging effect, forcing the connecting block 645 and the elastic sheet 643 connected thereto to further expand radially outward. The expansion of the elastic sheet 643 causes the pin 644 on its outer wall to be embedded deeper and tighter into the pin hole 63 of the embedded fixing tube 62, forming an adaptive locking mechanism; the disc spring 69 plays a role in buffering and providing continuous preload in this process; The effect is: under the action of external loads, especially pressure, the connecting mechanism 6 can automatically generate additional radial locking force, so that the pin 644 and the pin hole 63 are more tightly engaged, 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 setting of the disc spring 69 can absorb part of the impact energy, and help the embedded parts 5 and the connecting mechanism 6 to reset after the load is released, reducing residual deformation; and through the cooperation of the tapered sleeve 64, the cylindrical expansion sleeve 65, and the insert 66, the on-site installation steps are simplified, and the positioning accuracy of the embedded parts has a certain tolerance; finally, the combination of the pin 644 locking, thread tightening and wedging effects provides multi-level fixing guarantees.
