Description

Technical Field

[0001] This invention relates to the field of viscous damping wall technology, specifically a prefabricated insert-type viscous damping wall. Background Technology

[0002] Inserted plate viscous damping walls are a type of highly efficient energy dissipation and vibration reduction device. Their core working principle is to utilize the shear deformation of a high-viscosity liquid during motion to dissipate the energy input to the structure by earthquakes or wind loads. Inserted plate viscous damping walls consist of three core components:

[0003] The outer steel box and the viscous liquid: The outer steel box is a sealed box made of welded steel plates, usually fixed to the lower floor or frame beam, forming a relatively closed "cavity"; the viscous liquid is sealed inside the outer steel box and is a high-viscosity, non-flammable organosilicon or similar polymer material.

[0004] Metal shear plate: An internal component made of high-strength steel plate, shaped like a "plug plate", fixed to the upper floor or frame beam and inserted from the top down into an outer steel box filled with viscous fluid;

[0005] Auxiliary components include injection ports, positioning bolts, sealing caps, and anti-pull-out devices, which are used to ensure the normal operation and maintenance of the device.

[0006] The specific energy consumption process is as follows:

[0007] Initial state: The plate-type viscous damping wall does not provide calculable static stiffness, so under wind or minor earthquakes, it will not significantly change the vibration period and original mechanical properties of the main building structure;

[0008] Energy dissipation: When an earthquake or strong wind occurs, there will be relative movement (velocity difference) between the upper and lower floors of the building. This relative velocity forces the fixed internal steel plate of the upper floor to perform reciprocating shearing motion in the lower outer steel box filled with viscous fluid.

[0009] Energy conversion: The movement of the internal steel plates causes the high-viscosity viscous liquid to undergo severe shear deformation; the internal friction between liquid molecules and between the liquid and the steel plates generates resistance (i.e., damping force) to the movement of the steel plates, and in this process, the mechanical energy of the building vibration is converted into internal energy (heat energy) and consumed.

[0010] Achieving vibration reduction: Through this "viscous energy dissipation" mechanism, the seismic or wind-induced vibration energy input to the structure is effectively consumed, thereby significantly reducing the dynamic response and deformation that the main structure needs to withstand. This energy dissipation efficiency is very high. Related studies have shown that under certain conditions, it can significantly increase the first-order mode damping ratio of the structure from 1.4% to 17%.

[0011] Traditional insert-plate viscous damping walls have a damping force that is positively correlated with shear velocity. Under small displacements such as wind vibration or minor earthquakes, the shear plate moves slowly, the output force is small, and the effect is limited. Based on this, in order to enable the damping wall to work fully under small excitations and significantly improve the vibration reduction effect, a prefabricated insert-plate viscous damping wall is provided. Summary of the Invention

[0012] The purpose of this invention is to provide a prefabricated insert-type viscous damping wall in order to solve the problems mentioned above.

[0013] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated insert-type viscous damping wall, comprising a viscous damping wall composed of an outer steel box and a metal shear plate, wherein a lower connecting plate and a top width plate are respectively fixed at the upper and lower ends of the outer steel box, the outer steel box is installed to the lower floor through the lower connecting plate, and the metal shear plate is horizontally slidably installed inside the outer steel box and extends through the outer steel box and the lower connecting plate to the top of the lower connecting plate;

The upper connecting plate is fixed to the upper floor surface, and the fourth ear seat is symmetrically fixed to both ends of the bottom of the upper connecting plate.

[0016] A range extender drive assembly is provided between the upper connecting plate and the outer steel box. The range extender drive assembly is connected to the first lug, the third lug, and the fourth lug, and is used to extend the small displacement of the upper connecting plate to the metal shear plate to achieve a large displacement between the metal shear plate and the outer steel box.

[0017] The bottom of the upper connecting plate is fixed with a fifth ear at the outer end of the two fourth ear seats, and the top two ends of the top wide plate are fixed with second ear seats. When the range extender drive assembly is disassembled and replaced, the second ear seat and the fifth ear seat are connected and fixed by the first adjustable connecting assembly, and the second ear seat and the third ear seat are connected and fixed by the second adjustable connecting assembly.

[0018] A quick-release pin assembly is provided between the range extender drive assembly and the first, third, and fourth lugs, between the first adjustable connecting assembly and the second and fifth lugs, and between the second adjustable connecting assembly and the second and third lugs. The quick-release pin assembly is used to enable quick assembly and disassembly of the range extender drive assembly, the first adjustable connecting assembly, and the second adjustable connecting assembly.

[0020] Two support shafts are provided, and the two support shafts are vertically distributed and fixed to the rear end face of the inner wall of the transmission box;

[0021] The transmission pinion and transmission gear are fixedly connected by a connecting sleeve, and the transmission pinion and transmission gear are rotatably mounted on the outside of the upper support shaft as a whole.

[0022] The driven large gear and driven small gear are fixedly connected by a connecting cylinder, and the driven large gear and driven small gear are rotatably mounted on the outside of the lower support shaft as a whole;

[0023] The support shaft is located above the driven large gear and does not contact it, while the transmission large gear meshes with the driven small gear;

[0024] The transmission rack and driven rack are vertically parallel and distributed inside the transmission box and extend through both ends of the transmission box to the outside of the transmission box. The first connecting lug is symmetrically fixed to both ends of the transmission rack and driven rack.

[0025] The transmission rack and the driven rack have annular tooth grooves formed in the middle. The transmission rack is distributed above the support shaft and meshes with the support shaft. The driven rack is distributed below the driven large gear and meshes with the driven large gear.

[0026] The second connecting ear is provided in four parts, and the four second connecting ears are fixed to the bottom of the transmission box in a matrix arrangement;

[0027] The transmission box is located between the upper connecting plate and the outer steel box, and the four second connecting ears are respectively installed on the inner side of the four first ear seats. The first connecting ears at both ends of the driven gear are respectively connected to the two third ear seats on the top of the metal shear plate, and the two ends of the transmission gear are respectively connected to the two fourth ear seats at the bottom of the upper connecting plate.

[0028] The transmission structure, consisting of a transmission rack, a transmission pinion, a transmission gear, a driven pinion, a driven gear, and a driven rack, is used to convert the small displacement of the upper connecting plate into the large displacement of the metal shear plate.

[0029] As a further embodiment of the present invention: a front cover plate is installed on the front end face of the transmission box through a flange structure, and two support sleeves are fixed on the rear end face of the front cover plate. The two support sleeves are respectively sleeved with two support shafts and fit against the front end faces of the transmission large gear and the driven small gear.

[0030] As a further embodiment of the present invention: both the first adjustable connecting assembly and the second adjustable connecting assembly are composed of an adjusting cylinder, a connecting screw, a piston block, and a third connecting lug;

[0031] The connecting screw is provided in two parts, and the two connecting screws are symmetrically threaded to both ends of the adjusting cylinder. The helical directions of the outer threads of the two connecting screws are opposite. The rotation of the adjusting cylinder relative to the two connecting screws is used to move the two connecting screws away from each other or closer to each other.

[0032] The piston block is fixed to one end of the two connecting screws located inside the adjusting cylinder, and the piston block is slidably connected to the inner cavity of the adjusting cylinder.

[0033] The third connecting lug is symmetrically fixed to one end of the two connecting screws located outside the adjusting cylinder.

[0034] As a further embodiment of the present invention: the quick-connect pin assembly includes a through hole, an arc-shaped pin block, and a fastening bolt;

[0035] The insertion through hole is opened at the front end of the first ear seat, the second ear seat, the third ear seat, the fourth ear seat, and the fifth ear seat and extends completely to the rear end;

[0036] The arc-shaped pins are arranged in pairs. After the two arc-shaped pins pass through the insertion hole and the corresponding first connecting ear, second connecting ear, and third connecting ear, they are inserted between the two arc-shaped pins by fastening bolts and screwed together with the arc-shaped pins. This is used to realize the connection and assembly of the first connecting ear, second connecting ear, third connecting ear and viscous damping wall and upper connecting component.

[0039] When the two arc-shaped threaded sleeves are fitted together, the outer diameter of the two limiting half-rings is smaller than the inner diameter of the insertion hole, allowing them to pass smoothly through the insertion hole.

[0040] When the fastening bolt is inserted into the two arc-shaped threaded sleeves, the two limiting half-rings are engaged in the annular grooves and the two polygonal half-blocks are engaged in the polygonal grooves, which are used to achieve axial and rotational limiting of the arc-shaped threaded sleeves.

[0046] Compared with the prior art, the beneficial effects of the present invention are:

[0047] 1. By setting up a range extender drive assembly, the small displacement input from the upper floor can be mechanically amplified and transmitted to the metal shear plate. This allows the metal shear plate to still obtain a large shear stroke and movement speed under small displacement excitations such as wind vibration or small earthquakes, thereby fully stimulating the energy dissipation capacity of the viscous damping material and significantly improving the damping effect of the damping wall under small vibrations.

[0048] 2. By setting the first adjustable connection component and the second adjustable connection component, before replacing the range extender drive component (3), the upper connecting plate and the top width plate are rigidly locked and the top width plate and the metal shear plate are rigidly locked respectively by the above-mentioned adjustable connection components, which effectively prevents the installation reference from shifting due to the continuous deformation of the building structure or the sinking of the shear plate by its own weight, and ensures that the new component can be accurately aligned and installed.

[0049] 3. By setting up a quick-release pin assembly, the outer diameter of the two arc-shaped pins after merging is smaller than that of the insertion through hole, allowing them to be easily inserted. After tightening the fastening bolt, they open radially, achieving both axial locking (the limiting half-ring is inserted into the annular groove) and circumferential locking (the polygonal half-piece is inserted into the polygonal groove). During disassembly, the fastening bolt can be loosened in the opposite direction to pull it out. The entire process requires no special tools, and connection or separation can be completed within seconds, greatly improving the replacement efficiency of the range extender drive assembly.

[0067] Please see Figures 1 to 9 In this embodiment of the invention, a prefabricated insert-type viscous damping wall includes a viscous damping wall 1 composed of an outer steel box 101 and a metal shear plate 106.

The outer steel box 101 is installed to the lower floor through the lower connecting plate 102.

[0072] A quick-release pin assembly 4 is provided between the range extender drive assembly 3 and the first ear seat 104, the third ear seat 107, and the fourth ear seat 202; between the first adjustable connecting assembly 5a and the second ear seat 105 and the fifth ear seat 203; and between the second adjustable connecting assembly 5b and the second ear seat 105 and the third ear seat 107.

[0074] Two support shafts 302 are provided, and the two support shafts 302 are vertically distributed and fixed to the rear end face of the inner wall of the transmission box 301;

[0075] The transmission pinion 303 and the transmission gear 304 are fixedly connected by a connecting sleeve, and the transmission pinion 303 and the transmission gear 304 are rotatably mounted on the outside of the upper support shaft 302 as a whole.

[0077] The support shaft 302 is located above the driven large gear 305 and they do not contact each other, while the transmission large gear 304 meshes with the driven small gear 306;

[0078] The transmission rack 307 and the driven rack 308 are vertically parallel and distributed inside the transmission box 301 and pass through both ends of the transmission box 301 to the outside of the transmission box 301. The first connecting lug 309 is symmetrically fixed at both ends of the transmission rack 307 and the driven rack 308.

[0079] The transmission rack 307 and the driven rack 308 have annular tooth grooves formed in the middle. The transmission rack 307 is located above the support shaft 302 and meshes with the support shaft 302. The driven rack 308 is located below the driven large gear 305 and meshes with the driven large gear 305.

[0080] Four second connecting ears 312 are provided, and the four second connecting ears 312 are fixed to the bottom of the transmission box 301 in a matrix arrangement.

[0081] The transmission box 301 is located between the upper connecting plate 201 and the outer steel box 101, and the four second connecting ears 312 are respectively installed on the inner side of the four first ear seats 104. The first connecting ears 309 at both ends of the driven rack 308 are respectively connected to the two third ear seats 107 at the top of the metal shear plate 106, and the 109 at both ends of the transmission rack 307 are respectively connected to the two fourth ear seats 202 at the bottom of the upper connecting plate 201.

[0082] The transmission structure, consisting of a transmission rack 307, a transmission pinion 303, a transmission gear 304, a driven pinion 306, a driven gear 305, and a driven rack 308, is used to convert the small displacement of the upper connecting plate 201 into the large displacement of the metal shear plate 106.

[0083] In this embodiment, it should be further explained that: Figure 1 The viscous damping wall 1 shown, which consists of an outer steel box 101, a metal shear plate 106, a lower connecting plate 102, and a top width plate 103, is a mature existing structural technology in the field. Its internal structure, sealing method, and basic viscous energy dissipation principle are well known to those skilled in the art and are not the innovation of this invention. Therefore, they will not be described in detail here.

[0084] This prefabricated insert-type viscous damping wall amplifies the small displacement of the upper floor to the large displacement of the metal shear plate 106 through the range extender transmission component 3. During disassembly and replacement, the adjustable connection components (5a, 5b) are used to temporarily lock the key components, and the quick-release pin assembly (4) is used to achieve quick disassembly and assembly. The working principle of its viscous damping wall 1 during use is as follows:

[0085] When the building experiences wind vibration or a minor earthquake, the upper floor causes the upper connecting plate 201 to undergo a slight displacement. The upper connecting plate 201 is connected to the first connecting ear 309 at the end of the transmission rack 307 via two fourth ear seats 202. Therefore, the upper connecting plate 201 drives the transmission rack 307 to move horizontally synchronously. After that, the transmission operation is as follows.

[0086] The annular tooth groove of the transmission rack 307 meshes with the transmission pinion 303, driving the transmission pinion 303 to rotate → the coaxial transmission gear 304 rotates → the transmission gear 304 meshes with the driven pinion 306, driving the driven pinion 306 to rotate → the coaxial driven gear 305 rotates → the driven gear 305 meshes with the driven rack 308, thereby driving the driven rack 308 to move;

[0087] Due to the difference in the number of teeth between the large transmission gear 304 and the driven small gear 306, and the meshing between the driven large gear 305 and the driven rack 308, the displacement of the driven rack 308 is ultimately amplified (relative to the input displacement of the transmission rack 307).

[0088] At the same time, the two ends of the driven toothed rod 308 are connected to the third ear seat 107 on the top of the metal shear plate 106 through the first connecting ear 309, thereby driving the metal shear plate 106 to perform a large-stroke reciprocating shearing motion in the outer steel box 101, which greatly improves the viscous energy consumption efficiency.

[0089] When it is necessary to disassemble the range extender drive assembly 3, first install the first adjustable connecting assembly 5a, so that it connects the fifth ear 203 and the second ear 105, so that the upper connecting plate 201 is rigidly fixed to the top width plate 103 at the top of the outer steel box 101 to prevent the upper layer from shifting.

[0090] At the same time, the second adjustable connecting component 5b is installed to connect the second ear 105 and the third ear 107, locking the position of the metal shear plate 106 relative to the outer steel box 101 to prevent it from sinking or shifting.

[0091] Then, by quickly disassembling the connection between the range extender drive assembly 3 and each lug via the quick-release pin assembly 4, the transmission box 301 can be removed for repair or replacement.

[0092] During restoration, first install the new range extender drive assembly 3, then remove the adjustable connection assemblies (5a, 5b) to complete the non-destructive replacement.

[0093] Please refer to this carefully. Figures 1 to 5 The front end face of the transmission box 301 is fitted with a front cover plate 310 via a flange structure. The rear end face of the front cover plate 310 is fixed with two support sleeves 311. The two support sleeves 311 are respectively sleeved with two support shafts 302 and fit against the front end face of the transmission large gear 304 and the driven small gear 306.

[0094] In this embodiment: the rear ends of the two support shafts 302 inside the transmission box 301 are fixed to the inner wall of the box, and the front ends are suspended. The front cover plate 310 is sealed to the front end face of the transmission box 301 through a flange. The front cover plate 310 closes the box 301 to prevent impurities from entering the box 301.

[0095] In addition, the two support sleeves 311 are respectively fitted on the support shaft 302 and abut against the front end faces of the transmission large gear 304 and the driven small gear 306, thereby achieving axial positioning of the gear assembly and preventing the gear assembly from moving axially along the support shaft 302.

[0096] Meanwhile, radial auxiliary support is provided for the support shaft 302 to reduce the deflection deformation at the cantilever shaft end and improve transmission accuracy and service life;

[0097] It should also be noted that existing seals are provided at the contact points between the transmission box 301 and the transmission rack 307 and driven rack 308 to ensure good sealing and dust prevention.

[0098] Please refer to this carefully. Figures 8 to 9 The first adjustable connecting assembly 5a and the second adjustable connecting assembly 5b are both composed of an adjusting cylinder 501, a connecting screw 502, a piston block 503, and a third connecting lug 504.

[0099] There are two connecting screws 502. The two connecting screws 502 are symmetrically threaded to both ends of the adjusting cylinder 501, and the helical directions of the outer threads of the two connecting screws 502 are opposite. The rotation of the adjusting cylinder 501 relative to the two connecting screws 502 is used to move the two connecting screws 502 away from each other or closer to each other.

[0100] The piston block 503 is fixed to one end of the two connecting screws 502 located inside the adjusting cylinder 501, and the piston block 503 is slidably connected to the inner cavity of the adjusting cylinder 501.

[0101] The third connecting ear 504 is symmetrically fixed to one end of the two connecting screws 502 located outside the adjusting cylinder 501.

[0102] In this embodiment: the threads of the two connecting screws 502 are turned in opposite directions. When the adjusting cylinder 501 is rotated, the two screws extend outward or retract inward at the same time, so as to achieve stepless length adjustment.

[0103] Before replacing the range extender drive assembly 3, connect the third connecting ear 504 to the corresponding ear seat respectively, rotate the adjusting cylinder 501 to tension the assembly, thereby making the first adjustable connecting assembly 5a rigidly lock the upper connecting plate 201 and the top width plate 103, and the second adjustable connecting assembly 5b rigidly lock the top width plate 103 and the shear plate 106.

[0104] This ensures that the positions of the upper connecting plate 201 and the shear plate 106 remain unchanged, so as to facilitate the convenient installation of the new range extender drive assembly 3.

[0105] Please refer to this carefully. Figure 1 , Figure 2 , Figure 6 , Figure 7The quick-release pin assembly 4 includes a through hole 401, an arc-shaped pin block 404, and a fastening bolt 405;

[0106] The insertion through hole 401 is opened at the front end of the first ear seat 104, the second ear seat 105, the third ear seat 107, the fourth ear seat 202, and the fifth ear seat 203 and extends completely to the rear end;

[0107] The arc-shaped pins 404 are arranged in pairs. After the two arc-shaped pins 404 pass through the insertion hole 401 and the corresponding first connecting ear 309, second connecting ear 312, and third connecting ear 504, the fastening bolt 405 is inserted between the two arc-shaped pins 404 and threadedly connected and tightened to realize the connection and assembly of the first connecting ear 309, second connecting ear 312, and third connecting ear 504 with the viscous damping wall 1 and the upper connecting component 2.

[0108] The front ends of the first ear seat 104, the second ear seat 105, the third ear seat 107, the fourth ear seat 202, and the fifth ear seat 203 are provided with polygonal grooves 402 that are concentrically distributed with the insertion through hole 401, and the rear ends of the first ear seat 104, the second ear seat 105, the third ear seat 107, the fourth ear seat 202, and the fifth ear seat 203 are provided with annular grooves 403 that are concentrically distributed with the insertion through hole 401.

[0109] The arc-shaped pin block 404 is composed of an arc-shaped threaded sleeve 4041, a polygonal half-block 4042, and a limiting half-ring 4043. The polygonal half-block 4042 and the limiting half-ring 4043 are respectively fixed to the front and rear ends of the arc-shaped threaded sleeve 4041.

[0110] When the two arc-shaped threaded sleeves 4041 are fitted together, the outer diameter of the two limiting half-rings 4043 is smaller than the inner diameter of the insertion hole 401, so they can pass smoothly through the insertion hole 401.

[0111] When the fastening bolt 405 is inserted into the two arc-shaped threaded sleeves 4041, the two limiting half-rings 4043 are engaged in the annular groove 403 and the two polygonal half-pieces 4042 are engaged in the polygonal groove 402, which are used to realize the axial and rotational limiting of the arc-shaped threaded sleeves 4041.

[0112] In this embodiment: Traditional pins require integral insertion and the use of cotter pins, which is time-consuming to assemble and disassemble. This invention adopts a split arc-shaped pin block 404 structure:

[0113] After the two arc-shaped pins 404 are combined, their outer diameter is smaller than the inner diameter of the insertion through hole 401, so they can be easily inserted into the through holes of each ear seat and connecting ear. After insertion, the fastening bolt 405 is screwed between the two arc-shaped threaded sleeves 4041. The bolt head is spread open or tightened by the thread, so that the diameters 404 of the two arc-shaped pins are opened.

[0114] After opening, the rear limiting semi-ring 4043 is engaged in the annular groove 403 to achieve axial locking, while the front polygonal half block 4042 is engaged in the polygonal groove 402 to achieve circumferential locking.

[0115] During disassembly, loosen and remove the fastening bolt 405 by rotating it in the opposite direction. The arc-shaped pin 404 will retract radially, allowing the entire assembly to be pulled out. The entire process requires no special tools and can be completed in seconds, greatly improving on-site replacement efficiency.

[0116] Please refer to this carefully. Figure 1 , Figure 2 , Figure 8 The second ear seat 105 and the third ear seat 107 are each provided with two insertion holes 401, and the two insertion holes 401 are vertically distributed.

[0117] The first connecting lug 309 on the driven gear 308 is connected to the upper insertion through hole 401 on the third lug 107;

[0118] The two third connecting ears 504 on the first adjustable connecting assembly 5a are respectively connected to the upper insertion through holes 401 on the fifth ear seat 203 and the second ear seat 105;

[0119] The two third connecting ears 504 on the second adjustable connecting assembly 5b are respectively connected to the lower insertion through hole 401 on the second ear seat 105 and the lower insertion through hole 401 on the third ear seat 107.

[0120] In this embodiment: the second ear seat 105 and the third ear seat 107 are provided with two independent insertion holes 401, which respectively undertake different connection tasks:

[0121] The upper hole of the third ear seat 107 connects to the first connecting ear 309 at the end of the driven toothed rod 308, transmitting the amplified displacement to the shear plate;

[0122] The upper hole of the second ear seat 105 → connects to one end of the first adjustable connecting component 5a, and then connects to the fifth ear seat 203 to lock the upper connecting plate 201;

[0123] The lower hole of the third earpiece 107 connects to one end of the second adjustable connecting component 5b;

[0124] The lower hole of the second earpiece 105 connects to the other end of the second adjustable connecting component 5b;

[0125] This layered design avoids interference between different functional links, allowing the working link (range extender) and the temporary locking link (adjustable component) to coexist in the same lug without affecting each other.

[0126] Please refer to this carefully. Figures 1 to 2The arc-shaped pin 404 and the fastening bolt 405 corresponding to the first ear seat 104 pass through the first ear seat 104 aligned front and back, and the arc-shaped pin 404 on the first ear seat 104 does not contact the upper surface of the metal shear plate 106.

[0127] In this embodiment: With this structure, the transmission box 301 can be installed by means of two sets of arc-shaped pins 404 and fastening bolts 405;

[0128] Meanwhile, the metal shear plate 106 needs to slide laterally without friction during operation. If the pin assembly comes into contact with it, it will generate additional resistance or even jam. The arc-shaped pin block 404 on the first ear seat 104 does not come into contact with the upper surface of the metal shear plate 106. The reserved gap ensures that the shear plate can move freely, while avoiding the collision and wear between the pin and the shear plate due to vibration, thus improving the durability of the system.

[0129] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
