Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a building vibration reduction support. Background Art

[0002] Vibration is a common natural and man-made phenomenon. Whether it is a natural disaster earthquake or various vibration pollution generated in people's production and life, if it cannot be effectively controlled, it will bring harm to people's life, health and property. Therefore, various forms of earthquake-resistant and vibration-reducing bearings are widely used in various buildings such as buildings, bridges, and railroads.

[0003] When the existing vibration-damping bearing is in use, the vibration-damping rubber pad is generally installed under the supported object for support, based on the "flexible earthquake resistance" principle to consume vibration energy, thereby reducing the vibration of the building. However, when an earthquake or a subway passes by, not only horizontal vibration but also vertical vibration will be generated. However, the vibration-damping rubber pad generally only reduces the horizontal earthquake effect of the building, and cannot reduce the vertical vibration of the building caused by the subway passing along the subway line. The vibration reduction effect is poor and it is not convenient to use. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a building vibration reduction support to solve the problem that the horizontal and vertical vibrations cannot be reduced simultaneously by only using the vibration reduction rubber pad.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions: a building vibration reduction support, comprising a horizontal base, a concrete column and a wall to be supported, the concrete column and the wall to be supported are respectively arranged below and above the horizontal base, a vibration reduction rubber pad is installed on the top of the horizontal base, a mounting plate is installed on the top of the vibration reduction rubber pad, the mounting plate is installed in cooperation with the wall to be supported by fixing bolts, and a vibration reduction mechanism is arranged on the horizontal base;

[0006] The vibration reduction mechanism includes two movable grooves opened on the top of the horizontal base, and main viscous damping rods are arranged in the two movable grooves. Connecting blocks are installed on the sides of the mounting plate away from each other, and ball grooves are opened at the bottom of the two connecting blocks. Universal balls are movably installed in the two ball grooves. The two universal balls are respectively installed on the ends of the two main viscous damping rods. A secondary vibration reduction assembly adapted to the main viscous damping rod is arranged on the horizontal base, and the horizontal base is installed in cooperation with the concrete column through a fixing assembly.

[0008] Preferably, the elastic unit includes buffer springs respectively mounted on the back and side of the moving block, and the other ends of the two buffer springs are respectively mounted on the side inner wall of the movable groove and the side wall of the movable box.

[0009] Preferably, the fixing assembly includes four anchor columns fixed to the top of the concrete column, the outer walls of the four anchor columns are provided with clamping holes, the top of the horizontal base is provided with four avoidance holes matched with the anchor columns, the top of the horizontal base is provided with four slide grooves, the relative inner walls of the four slide grooves are provided with sliding rods, the four slide rods are slidably sleeved with L-shaped clamping blocks matched with the clamping holes, and the horizontal base is provided with a driving unit that enables the four L-shaped clamping blocks to move simultaneously.

[0012] The beneficial effects of the utility model are as follows:

[0013] The utility model can reduce vibration in the horizontal direction through the vibration-damping rubber pad. At the same time, the vibration-damping rubber pad will move when it is vibrated. The movement of the vibration-damping rubber pad will cause the main viscous damping rod to be forced to contract through the connecting block and the universal ball, thereby causing the main viscous damping rod to reduce vibration for vertical vibration. At the same time, the main viscous damping rod will move when it is forced. At this time, the moving block and the movable box will move together.

The vibration reduction effect is better and at the same time it can prevent the main viscous damping rod from being damaged due to excessive pulling force caused by the inability to move horizontally with the mounting plate.

[0014] The utility model can make two threaded blocks approach each other through the knob and the bidirectional screw rod. The approach of the two threaded blocks to each other will cause the two connecting plates to move. The movement of the two connecting plates will cause the four L-shaped clamping blocks to enter and penetrate the clamping holes on the four anchor rods, so that the horizontal base can be fixed to the concrete column from four directions at one time, reducing the fixing time and facilitating installation and construction. At the same time, the bidirectional screw rod can be further fixed by tightening bolts to prevent the bidirectional screw rod from rotating itself and affecting the fixing effect.

[0020] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0021] Figures 1 to 4 It is the best embodiment of the utility model, and the following Figures 1 to 4 The utility model is further described.

[0022] A building vibration-damping support, comprising a horizontal base 1, a concrete column 12 and a wall 13 to be supported, wherein the concrete column 12 and the wall 13 to be supported are respectively arranged below and above the horizontal base 1. Specifically, the concrete column 12 and the wall 13 to be supported are prior art and will not be described in detail herein. A vibration-damping rubber pad 2 is installed on the top of the horizontal base 1, and a mounting plate 3 is installed on the top of the vibration-damping rubber pad 2. The mounting plate 3 is installed in cooperation with the wall 13 to be supported by fixing bolts, and a vibration-damping mechanism is arranged on the horizontal base 1.

[0023] The vibration reduction mechanism includes two movable grooves opened on the top of the horizontal base 1, and main viscous damping rods 9 are arranged in the two movable grooves. Specifically, the main viscous damping rod 9 is a prior art, and is composed of a cylinder body, a piston, a piston rod and a viscous fluid filled in the cylinder body. When in use, the energy input by the earthquake can be converted into heat energy and dissipated, thereby reducing the seismic response of the structure. Connecting blocks 10 are installed on the sides of the mounting plate 3 away from each other, and ball grooves are opened at the bottoms of the two connecting blocks 10. Universal balls 11 are movably installed in the two ball grooves. The two universal balls 11 are respectively installed at the ends of the two main viscous damping rods 9. A secondary vibration reduction component compatible with the main viscous damping rod 9 is arranged on the horizontal base 1, and the horizontal base 1 is installed in cooperation with the concrete column 12 through a fixing component.

[0024] In this solution, the horizontal base 1, the vibration-damping rubber pad 2, the mounting plate 3, the main viscous damping rod 9, the connecting block 10, the universal ball 11, and the concrete column 12 are arranged to facilitate vibration reduction in the horizontal and vertical directions.

[0025] Specifically, when vibration occurs, the vibration-damping rubber pad 2 will reduce vibration from the horizontal direction to reduce the horizontal shear force of the vibration-supporting wall 13. At the same time, it can reduce vibration from the vertical direction through the mounting plate 3, the main viscous damping rod 9, the connecting block 10 and the universal ball 11, thereby reducing horizontal and vertical vibrations and achieving a better vibration reduction effect.

[0026] The secondary vibration reduction assembly includes two fixed rods respectively installed on the relative inner walls of the two movable grooves, and a moving block 4 is slidably sleeved on each two matching fixed rods. The side inner walls of the two movable grooves are installed with first auxiliary viscous damping rods 5, and the two moving blocks 4 are respectively installed on the ends of the two first auxiliary viscous damping rods 5. The sides of the two moving blocks 4 are respectively installed with second auxiliary viscous damping rods 7, and the ends of the two second auxiliary viscous damping rods 7 are respectively installed with movable boxes 8, and the two main viscous damping rods 9 are respectively installed on the bottom inner walls of the two movable boxes 8, and elastic units are provided on the two moving blocks 4.

[0027] In this solution, the movable block 4, the first auxiliary viscous damping rod 5, the second auxiliary viscous damping rod 7 and the movable box 8 are arranged to facilitate the secondary vibration reduction.

[0028] Specifically, when the vibration-damping rubber pad 2 is performing vibration reduction, the mounting plate 3 will be displaced horizontally, which will cause the main viscous damping rod 9 to move. When the main viscous damping rod 9 moves, the movable box 8 will move. At this time, the first auxiliary viscous damping rod 5 and the second auxiliary viscous damping rod 7 will convert the force of the movable box 8 to achieve secondary vibration reduction. At the same time, the main viscous damping rod 9 can be moved to avoid the main viscous damping rod 9 being unable to move horizontally with the mounting plate 3, causing excessive pulling force and resulting in damage.

[0029] The elastic unit includes buffer springs 6 respectively mounted on the back and side of the moving block 4 , and the other ends of the two buffer springs 6 are respectively mounted on the side inner wall of the movable groove and the side wall of the movable box 8 .

[0030] In this solution, by providing the buffer spring 6, a certain buffer effect is increased, and at the same time, it is convenient to reset the movable box 8.

[0031] The fixing assembly includes four anchor columns 14 fixed to the top of the concrete column 12, the outer walls of the four anchor columns 14 are provided with clamping holes, the top of the horizontal base 1 is provided with four avoidance holes matched with the anchor columns 14, the top of the horizontal base 1 is provided with four slide grooves, the relative inner walls of the four slide grooves are installed with sliding rods, the four slide rods are slidably sleeved with L-shaped clamping blocks 15 matched with the clamping holes, and the horizontal base 1 is provided with a driving unit that enables the four L-shaped clamping blocks 15 to move simultaneously.

[0032] In this solution, the horizontal base 1 is conveniently connected to the concrete column 12 by providing the anchor column 14 , the slide rod and the L-shaped block 15 .

[0033] Specifically, the driving unit can make the L-shaped block 15 pass through the hole on the anchor column 14. At this time, the horizontal base 1 cannot be moved, so there is no need to rotate multiple bolts for fixing, which reduces the fixing time.

[0034] The driving unit includes a groove opened on the top of the horizontal base 1, and a bidirectional screw rod 16 is rotatably installed on the relative inner wall of the groove. One end of the bidirectional screw rod 16 extends to the outside of the horizontal base 1 and is installed with a knob. Two threaded blocks 17 are threadedly sleeved on the bidirectional screw rod 16, and connecting plates 18 are installed on the sides of the two threaded blocks 17. Two L-shaped blocks 15 on one side are installed on the side of one of the connecting plates 18.

[0035] In this solution, the two-way screw rod 16, the knob, the threaded block 17 and the connecting plate 18 are arranged to facilitate the simultaneous movement of the four L-shaped blocks 15.

[0036] Specifically, the connecting plate 18 can be moved by the bidirectional screw rod 16, the knob and the threaded block 17. The movement of the connecting plate 18 will cause the four L-shaped blocks 15 to move simultaneously, thereby fixing the horizontal base 1 to the concrete column 12 from four directions at one time, reducing the fixing time and facilitating installation and construction.

[0037] A threaded hole is provided on the side of the horizontal base 1 , and a fastening bolt 19 is movably installed on the threaded hole. The end of the fastening bolt 19 is tightly pressed against the bidirectional screw rod 16 .

[0038] In this solution, the fastening bolts 19 are provided to facilitate fixing the bidirectional screw rod 16 , thereby preventing the bidirectional screw rod 16 from rotating itself and causing the L-shaped block 15 to move, thereby affecting the fixing effect.

[0039] In summary: when the utility model is in use, first align the four avoidance holes on the horizontal base 1 with the four anchor columns 14 on the concrete column 12, then place the horizontal base 1 on the concrete column 12, and then turn the knob. The rotation of the knob will cause the two-way screw rod 16 to rotate, and the rotation of the two-way screw rod 16 will cause the two threaded blocks 17 to move. The movement of the two threaded blocks 17 will cause the two connecting plates 18 to move. The movement of the two connecting plates 18 will cause the four L-shaped blocks 15 to move, and then the four L-shaped blocks 15 move and enter and pass through the holes on the four anchor columns 14 at the same time, so that the horizontal base 1 can be fixed to the concrete column 12 from four directions at one time, reducing the fixing time and facilitating installation and construction. When the horizontal base 1 is installed, the mounting plate 3 and the wall to be supported 13 are installed by fixing bolts for vibration reduction support.

[0040] When vibration occurs, the vibration will be transmitted to the horizontal base 1 through the concrete column 12 and the anchor column 14. At this time, the vibration-damping rubber pad 2 plays a certain vibration-damping role, reducing the horizontal shear force of the vibration-damping supporting wall 13. At the same time, the vibration-damping rubber pad 2 will be horizontally displaced by the horizontal earthquake. When the vibration-damping rubber pad 2 is horizontally displaced, the mounting plate 3 will move. The movement of the mounting plate 3 will cause the universal ball 11 to be horizontally displaced through the connecting block 10. The movement of the universal ball 11 will cause the main viscous damping rod 9 to be forced to contract. At this time, the main viscous damping rod 9 will convert the energy and then reduce the vertical vibration. At the same time, when the vibration-damping rubber pad 2 is horizontally and longitudinally displaced, the universal ball 11 will be horizontally and longitudinally displaced through the mounting plate 3 and the connecting block 10. The horizontal and longitudinal displacement of the universal ball 11 will cause the main viscous damping rod 9 to be moved through the fixed rod, the moving block 4 and the movable box 8. It is subjected to force and moves horizontally and longitudinally. At this time, the first auxiliary viscous damping rod 5 and one of the buffer springs 6 are subjected to force. The force on the first auxiliary viscous damping rod 5 and one of the buffer springs 6 will transform the horizontal and longitudinal force, and then reduce the horizontal and longitudinal vibration. When the vibration-damping rubber pad 2 is displaced horizontally and laterally, the main viscous damping rod 9 will be subjected to force and move horizontally and laterally through the second auxiliary viscous damping rod 7, the movable box 8 and the universal ball 11. At this time, the second auxiliary viscous damping rod 7 and another buffer spring 6 are subjected to force. The force on the second auxiliary viscous damping rod 7 and another buffer spring 6 will transform the horizontal and transverse force, and then reduce the horizontal and transverse vibration, thereby playing the role of secondary vibration reduction, with better vibration reduction effect, and at the same time avoiding the main viscous damping rod 9 from being unable to move horizontally with the mounting plate 3 due to excessive pulling force and damage.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
