Description

Technical Field

[0001] The invention belongs to the technical field of shock-absorbing buildings, and in particular relates to a damping and shock-absorbing assembled prefabricated shear wall. Background Art

[0002] Shear walls are used in houses or buildings to bear horizontal loads caused by wind loads or earthquakes. They are also called earthquake-resistant walls. Unlike heavy walls, shear walls mainly bear vertical loads. In order to build buildings quickly, prefabricated walls are transported to the installation site for assembly. In order to improve the earthquake resistance of shear walls, dampers are installed at the shear wall connecting beams for shock absorption.

[0003] The Chinese invention application with application number "CN202010830646.8" discloses a composite friction damper, including an upper connecting plate and a lower connecting plate, wherein the upper connecting plate is provided with a central core plate and two large side plates, and the lower connecting plate is provided with two friction plates. The friction plate of the above invention will generate friction, and the elastic plate will be slightly deformed accordingly. There will be no cold bonding or cold solidification between the central core plate and the two friction plates, and between the two large side plates and the two friction plates, thereby optimizing the load bearing capacity;

[0004] Friction dampers are generally installed in buildings, so they need to be used for a long time. The number of frictions between the friction plates on both sides and the friction steel plate in the middle will be very large, especially in areas with strong winds or frequent earthquakes. The friction plates on both sides and the friction steel plate in the middle will be worn and thinned during the friction process. This will cause the friction dampers in some areas with strong winds or frequent earthquakes to fail prematurely. After failure, since there will be no friction damping, the seismic resistance of the shear wall may decrease. Because the friction surfaces are all inside the friction damper, the operation and maintenance personnel cannot quickly discover and replace or repair them. Summary of the invention

[0038] The piston shaft 34 is located on the side of the waterproof breathable valve 35 close to the prefabricated wall 1. A waist-shaped movable groove 37 is opened in the middle of the friction steel plate 31. The friction steel plate 31 is movably connected with the limiting rod 36 through the waist-shaped movable groove 37. The mounting shell 32 can move along the waist-shaped movable groove 37 through the limiting rod 36.

[0039] A drawstring 6 is fixedly connected to one side of the bevel rack 2 45 near the spring assembly 1 44, and a support block 61 is fixedly connected to the spray pipe 25 near the drawstring 6, and the drawstring 6 is sleeved on the surface of the support block 61;

[0040] In this embodiment, the prefabricated wall 1 is prefabricated and the damping mechanism 3, the gas transmission mechanism 4, the adjustment mechanism 5, and the pull rope 6 are installed with the prefabricated wall 1, and then the prefabricated wall 1 is installed in the building. At this time, except for the water storage tank 21, the delivery pipe 22, the one-way water inlet valve 23, and the plug 24 located at the bottom of the prefabricated wall 1, the other components are located at the connecting beam of the prefabricated wall 1, and the other side of the connecting beam can be connected to other prefabricated walls 1 or other structures in the building;

[0041] When the prefabricated wall 1 bears a relatively small daily horizontal load, such as a wind load, the friction plate 56 is driven to fit with the friction steel plate 31 only by the thrust generated by the reset spring 2 52 and the spring assembly 2 54. At this time, the friction damping force is moderate. When the prefabricated wall 1 vibrates slightly, the friction steel plate 31 and the mounting shell 32 are relatively displaced. The friction steel plate 31 fits with the friction plate 56 to generate friction damping, thereby reducing the shock of the prefabricated wall 1. In addition, the piston shaft 34 does not move much in the piston cylinder 1 33 and will not cross the waterproof breathable valve 35.

[0042] When an earthquake or a very large wind load occurs, the amplitude of the shaking of the prefabricated wall 1 increases, thereby increasing the relative displacement distance between the friction steel plate 31 and the mounting shell 32. At this time, the friction steel plate 31 drives the piston shaft 34 to pass over the waterproof breathable valve 35. After the piston shaft 34 passes over the waterproof breathable valve 35, a sealed space is formed between the piston shaft 34 and the piston plate 1 42, thereby pushing the piston plate 1 42 to move in the direction of the piston cylinder 2 46. Moreover, through the clamping of the bevel rack 2 45 and the bevel rack 1 43, the piston plate 1 42 can only drive the piston plate 2 47 to move in the direction of the piston cylinder 2 46 at this time.

[0043] When the bevel rack 1 43 moves, it drives the piston plate 2 47 to move in the inner cavity of the piston cylinder 2 46, and pushes the air in the inner cavity of the piston cylinder 2 46 into the inner cavity of the piston cylinder 3 51 along the connecting pipe 48, thereby increasing the air pressure in the inner cavity of the piston cylinder 3 51. The higher air pressure drives the piston plate 3 53 and the spring assembly 2 54 to drive the locking assembly 55 to push the friction plate 56 and the friction steel plate 31 to fit more closely, thereby increasing the friction damping force. In this way, when the daily shock absorption bears horizontal loads, the moderate friction damping force of the friction steel plate 31 and the friction plate 56 is used to reduce shock and dissipate energy. When the horizontal load on the prefabricated wall 1 increases, the fit between the friction plate 56 and the friction steel plate 31 is increased, thereby increasing the friction damping force, thereby avoiding the friction plate 31 and the friction plate 56 from always keeping a close fit, resulting in the friction plate 56 and the friction steel plate 31 also suffering from greater wear under the daily smaller shaking amplitude, thereby reducing the service life.

[0044] When the friction plate 56 needs to be reset, the pull rope 6 is pulled to drive the cone rack 2 45 and the cone rack 1 43 to separate. At this time, the piston plate 1 42 is reset by the elasticity of the reset spring 1 41, and the piston plate 2 47 is reset. When the piston plate 2 47 is reset, more air in the inner cavity of the piston cylinder 3 51 returns to the inner cavity of the piston cylinder 2 46 through the connecting pipe 48;

[0045] After the friction plate 56 has been used for a long time, the wear between the friction steel plate 31 and the friction plate 56 will increase, and the thickness of the friction plate 56 will decrease. At this time, the elasticity of the return spring 2 52 drives the piston plate 3 53, the spring assembly 2 54, the locking assembly 55, and the friction plate 56 to move toward the friction steel plate 31, so that the friction steel plate 31 can always keep in contact with the friction steel plate 31 with a small damping. At this time, the external air is sucked into the inner cavity of the piston cylinder 3 51 through the one-way intake valve 511, so that the inner cavity of the piston cylinder 3 51 keeps a normal pressure state during daily use, so that when the friction plate 56 is worn, it can also keep in contact with the friction steel plate 31, avoiding the situation that the friction damping force decreases after wear;

[0046] When the friction plate 56 is completely worn out, the locking assembly 55 loses the limit of the friction plate 56. At this time, the spring assembly 2 54 releases its elasticity to drive the reminder tube 552 to pass through the plurality of circular plug-in slots 57 and be located outside the mounting shell 32. At this time, the bright color of the reminder tube 552 reminds the maintenance personnel, so that they can be informed more quickly and intuitively that replacement is required, so that the maintenance personnel can avoid not knowing whether the friction plate 56 is completely worn out because they cannot observe the inside of the mounting shell 32.

[0047] Furthermore, the load-bearing tube 551 is located between the plurality of circular insertion grooves 57, thereby making the friction steel plate 31 and the mounting shell 32 rigidly connected, thereby achieving effective support for the prefabricated wall 1 through the rigid connection even after the friction damping performance is lost.

[0048] Embodiment 2

[0049] like Figures 1 to 7 As shown, an embodiment of the present invention provides a damping and shock-absorbing assembled prefabricated shear wall, the heat dissipation mechanism 2 includes a water storage tank 21, the water storage tank 21 is fixedly connected to the bottom of the prefabricated wall 1, the top of the piston cylinder 33 is fixedly connected to a delivery pipe 22, the bottom of the delivery pipe 22 is fixedly connected to a one-way water inlet valve 23, the bottom of the delivery pipe 22 is located at the bottom end of the inner cavity of the water storage tank 21, the top of the water storage tank 21 is plugged with a plug 24, the end of the piston cylinder 33 away from the limit rod 36 is fixedly connected to a spray pipe 25, and the end of the spray pipe 25 close to the piston cylinder 33 is fixedly connected to a one-way water outlet valve 26.

[0050] The heat dissipation mechanism 2 further includes a heat sink 27, which is fixedly connected to a side of the mounting plate 58 away from the friction steel plate 31 and is located outside the mounting shell 32, and the spray pipe 25 is located above the heat sink 27;

[0051] In this embodiment, when the piston shaft 34 moves in the inner cavity of the piston cylinder 33 toward the piston plate 42, the water in the inner cavity of the water storage tank 21 is drawn into the inner cavity of the piston cylinder 33 along the one-way water inlet valve 23 and the delivery pipe 22 through the delivery pipe 22 and is located on the side of the piston shaft 34 away from the piston plate 42. When the piston shaft 34 moves in the inner cavity of the piston cylinder 33 away from the piston plate 42, the water in the inner cavity of the piston cylinder 33 is squeezed out along the spray pipe 25 and the one-way water outlet valve 26 and sprayed onto the surface of the heat sink 27. Then, the heat generated by the friction plate 56 during the friction process is dissipated into the air through the heat sink 27, thereby avoiding the situation where the temperature between the friction plate 56 and the friction steel plate 31 is high, resulting in a decrease in friction damping performance.

[0052] Working principle and use process: When making the prefabricated wall 1, the damping mechanism 3, the gas transmission mechanism 4, the adjustment mechanism 5, the pull rope 6 are installed with the prefabricated wall 1. When in use, the prefabricated wall 1 is installed in the building. At this time, except for the water storage tank 21, the delivery pipe 22, the one-way water inlet valve 23, and the plug 24 located at the bottom of the prefabricated wall 1, other components are located at the connecting beam of the prefabricated wall 1;

[0053] When the prefabricated wall 1 is bearing a daily small horizontal load, the prefabricated wall 1 vibrates slightly, at which time the friction steel plate 31 and the mounting shell 32 are relatively displaced, and the displacement is small, and the thrust of the return spring 2 52 and the spring assembly 2 54 drives the friction plate 56 to contact the friction steel plate 31. When the friction steel plate 31 moves slightly, the damping force between the friction plate 56 and the friction steel plate 31 is moderate, and the prefabricated wall 1 is damped by the friction damping between the friction plate 56 and the friction steel plate 31.

[0054] When the friction steel plate 31 and the mounting shell 32 are relatively displaced, the friction between the friction steel plate 31 and the friction plate 56 will increase the heat of the friction plate 56 and the friction steel plate 31, and will also drive the piston shaft 34 to move slightly in the inner cavity of the piston cylinder 33, and will not cross the waterproof breathable valve 35. When the piston shaft 34 moves in the direction of the waterproof breathable valve 35, the water in the inner cavity of the water storage tank 21 is pumped out through the delivery pipe 22 and the one-way water inlet valve 23, and the pumped water is transported to the inner cavity of the piston cylinder 33 along the delivery pipe 22. When the piston shaft 34 moves in the direction of the waterproof breathable valve 35, the water in the inner cavity of the piston cylinder 33 is squeezed out along the spray pipe 25 and the one-way water outlet valve 26 and sprayed onto the surface of the heat sink 27, so that the heat of the friction plate 56 is transferred to the external air through the heat sink 27 for heat dissipation.

[0055] When an earthquake occurs or the wind volume is large, the horizontal load on the prefabricated wall 1 is large, and the amount of shaking of the prefabricated wall 1 increases, so the relative displacement between the friction steel plate 31 and the friction plate 56 increases, and the piston shaft 34 will pass over the waterproof breathable valve 35. After the piston shaft 34 passes over the waterproof breathable valve 35, a sealed space will be formed between the piston shaft 34 and the piston plate 1 42, and then the piston plate 1 42, the bevel rack 1 43, and the piston plate 2 47 are pushed toward the direction of the connecting pipe 48. At this time, the bevel rack 1 43 and the bevel rack 2 45 are clamped together. , so that the bevel rack 1 43 will be locked after moving, and when the piston plate 2 47 moves in the inner cavity of the piston cylinder 2 46, the air in the inner cavity of the piston cylinder 2 46 will be transported to the inner cavity of the piston cylinder 3 51 along the connecting pipe 48, thereby increasing the amount of gas in the inner cavity of the piston cylinder 3 51 and raising the air pressure. The piston plate 3 53 is pushed by the higher air pressure, and the friction plate 56 is pushed to fit more closely with the friction steel plate 31 through the spring assembly 2 54 and the locking assembly 55, thereby increasing the friction damping force between the friction plate 56 and the friction steel plate 31;

[0056] After the large shaking ends, the maintenance personnel pulls the pull rope 6 downward to move the bevel rack 2 45 toward the direction of the spring assembly 1 44;

[0057] When the friction plate 56 has been used for a long time, the friction plate 56 will gradually become thinner due to the friction with the friction steel plate 31. At this time, the elasticity of the return spring 2 52 can drive the friction plate 56 to always fit the friction steel plate 31 with less damping. When the friction plate 56 is completely worn out, the elasticity of the spring component 2 54 drives the locking component 55 to pass through the multiple circular plug-in grooves 57, so that the reminder tube 552 is located on the outside of the installation shell 32. At this time, the more eye-catching color of the reminder tube 552 is used to remind the operation and maintenance personnel, and the load-bearing tube 551 is located between the multiple circular plug-in grooves 57 to lock the installation shell 32 and the friction steel plate 31, so that the friction steel plate 31 and the installation shell 32 become rigidly connected to support the connecting beam of the prefabricated wall 1.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
