Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building seismic isolation, and particularly relates to a reinforcing, shockproof and anti-seismic device for buildings such as bridges. BACKGROUND

[0002] Earthquake is a common and destructive natural disaster, and is sudden and unpredictable. China is a country with high building density and volume rate, and earthquakes occur frequently, with wide distribution, high frequency and great intensity. Each time a large-intensity earthquake occurs, it will cause immeasurable loss of life and property, so it is an important research topic in the field of civil construction to make preparations for earthquake prevention and resistance in advance.

[0003] In addition to earthquakes, other forms of vibration are ubiquitous, such as air flow, vehicle travel, noise, etc., which will cause vibration of buildings. These ubiquitous vibrations not only affect the service life of buildings, but also affect the accuracy of equipment in buildings, so it is particularly urgent to develop equipment for building vibration reduction.

[0004] At present, common damping systems include laminated rubber pad seismic isolation system, combined seismic isolation system, sliding friction seismic isolation system, etc., and the essence of all of them is to isolate the building from ground vibration to provide appropriate damping or increase the flexibility of the system, so as to reduce vibration.

[0005] Regardless of the specific structure of the damping medium shock absorber, such as "viscous damping", "friction sliding damping", "frequency modulation damping", "metal soft steel damping", "bridge fluid viscous damping", "viscous damping wall", etc., it is a one-way bearing seismic wave, and the damping medium needs a direction control device. However, the earthquake wave is unpredictable, and this type of shock absorber cannot fundamentally solve the earthquake wave from different directions. Therefore, it is necessary to develop a shock-absorbing device that can simultaneously reduce or absorb earthquake waves from different directions. SUMMARY

[0006] The purpose of the present application is to solve the problems of the prior art, and to provide a lantern type building shock absorber which is simple in structure, safe and reliable, and convenient to adjust. The technical scheme adopted by the present application is as follows:

[0007] A lantern type building shock absorber, comprising an elastic damping assembly and a universal connecting assembly;

[0008] The universal connecting assembly comprises a spherical hinge seat, a spherical hinge cover and a ball head, the spherical hinge seat and the spherical hinge cover are detachably connected, a spherical hollow cavity is formed between the spherical hinge seat and the spherical hinge cover, the ball head is universally hinged with the cavity, and a screw rod part is connected to one side of the ball head;

[0009] The elastic damping assembly comprises a plurality of steel wires, a bowl-shaped fastener and a bowl-shaped coupler, the bowl-shaped fastener and the bowl-shaped coupler are detachably connected, the plurality of steel wires are circumferentially and uniformly arranged, one end of each of the plurality of steel wires is clamped between a group of the bowl-shaped fasteners and the bowl-shaped coupler, and the other end of each of the plurality of steel wires is clamped between another group of the bowl-shaped fasteners and the bowl-shaped coupler.

[0010] The ball joint seats of the two universal connecting assemblies are respectively connected with the building foundation and the building body, and the screw rods of the two universal connecting assemblies are respectively connected with the two bowl-shaped couplers.

[0011] Further, the outer surface of the bowl-shaped fastener and the inner surface of the bowl-shaped coupler are both in the shape of the long axis end of an ellipse, and the long axis and the focus of the outer surface of the bowl-shaped fastener and the inner surface of the bowl-shaped coupler are coincident, and the plurality of steel wires are in the shape of the short axis end of an ellipse, and the elastic damping assembly is in the shape of an ellipsoid.

[0012] Further, the outer surface of the bowl-shaped fastener and the inner surface of the bowl-shaped coupler are respectively circumferentially provided with a plurality of grooves matched with the steel wires, and the plurality of steel wires are one-to-one correspondingly clamped in the grooves of the bowl-shaped fastener and the bowl-shaped coupler.

[0013] Further, the number of the steel wires is at least three.

[0014] Further, the steel wires are twisted from seven steel wire materials.

[0015] Compared with the prior art, the beneficial effects of the present application are as follows:

[0016] The present application can be used for reinforcing, shockproofing and anti-seismic of buildings, and can be installed horizontally, vertically or at any angle according to different installation positions. Since the ball head is spherical, it can rotate in any direction in the cavity formed between the ball joint seat and the ball joint cover, so that the building can transmit the vibration to the ball head through the ball joint seat no matter in which direction the vibration is, and the ball head can transmit the vibration to the plurality of steel wires through the ball joint coupler and the bowl-shaped fastener. Since the plurality of steel wires are circumferentially and uniformly arranged, the plurality of steel wires can absorb the vibration energy transmitted from any direction. The steel wires have high elasticity and can bear longitudinal force, transverse force or torsional force, or a composite force of multiple forces. Since the shock absorber is in the shape of a lantern, each single steel wire is like a “bow” of a bow and arrow, so each single steel wire has a damping function, and the lantern-type shock absorber with multiple circumferentially and uniformly arranged steel wires has strong damping function.

[0033] The present application will be further described in detail below with reference to the accompanying drawings, the following examples are an explanation of the present application, and the present application is not limited to the following examples.

[0034] Embodiment: as shown in the drawing, a lantern type building shock absorber comprises a elastic damping assembly 2 and a universal connecting assembly 1; Figures 1-13 The universal connecting assembly 1 comprises a spherical hinge seat 3, a spherical hinge cover 4 and a ball head 5, the spherical hinge seat 3 and the spherical hinge cover 4 are detachably connected, a spherical cavity is formed between the spherical hinge seat 3 and the spherical hinge cover 4, the ball head 5 is universally hinged with the cavity, and one side of the ball head 5 is connected with a screw rod part 10;

[0035] The elastic damping assembly 2 comprises a bowl-shaped fastener 6, a bowl-shaped coupler 8 and a plurality of steel wire ropes 7, the bowl-shaped fastener 6 and the bowl-shaped coupler 8 are detachably connected, the plurality of steel wire ropes 7 are circumferentially uniformly arranged, one end of the plurality of steel wire ropes 7 is clamped between a group of the bowl-shaped fastener 6 and the bowl-shaped coupler 8, and the other end of the plurality of steel wire ropes 7 is clamped between another group of the bowl-shaped fastener 6 and the bowl-shaped coupler 8;

[0036] The spherical hinge seats 3 of the two universal connecting assemblies 1 are respectively connected with the building foundation and the building main body in correspondence, and the screw rod parts 10 of the two universal connecting assemblies 1 are respectively connected with the two bowl-shaped couplers 8 in one-to-one correspondence.

[0037] The outer surface of the bowl-shaped fastener 6 and the inner surface profile of the bowl-shaped coupler 8 are both in the shape of the long axis end line of an ellipse, and the long axis and the focus of the outer surface of the bowl-shaped fastener 6 and the inner surface profile of the bowl-shaped coupler 8 are coincident, the plurality of steel wire ropes 7 are in the shape of the short axis end line of an ellipse, and the elastic damping assembly 2 is in the shape of an ellipsoid.

[0038] The outer surface of the bowl-shaped fastener 6 and the inner surface of the bowl-shaped coupler 8 are respectively circumferentially provided with a plurality of grooves 9 adapted to the steel wire ropes 7, the plurality of steel wire ropes 7 are clamped in the grooves 9 of the bowl-shaped fastener 6 and the bowl-shaped coupler 8 in one-to-one correspondence, and the bowl-shaped fastener 6 and the bowl-shaped coupler 8 realize clamping of the steel wire ropes 7 through the bolts and make the steel wire ropes 7, the bowl-shaped fastener 6 and the bowl-shaped coupler 8 into an integral whole.

[0039]

[0040] ​The number of the steel wire ropes 7 is at least three.

[0041] The steel wire rope 7 is twisted by seven steel wire strands.

[0042] The present application can be used for reinforcement, shockproof and anti-shock of buildings, and the device can be installed horizontally, vertically or at any angle according to the installation position.

[0043] Since the ball head 5 is spherical, it can rotate in any direction in the cavity formed between the ball hinge base 3 and the ball hinge cover 4, so that the building can transmit the vibration to the ball head 5 through the ball hinge base 3 no matter in which direction the vibration is, and the ball head 5 can transmit the vibration to the steel wire ropes 7 through the ball hinge coupling 8 and the bowl-shaped fastener 6, and since the steel wire ropes 7 are uniformly distributed in the circumference, the steel wire ropes 7 can absorb the vibration energy transmitted from any direction.

[0044] The two ends of the present application are symmetrical, and the natural extension length of the shock absorber is greater than the length of the two end connection bases by adding the deformation length of the additional steel wire ropes 7 according to the installation size of the two ends, and under the limitation of the two end ball hinge bases 3, the elastic shock absorbing assembly 2 will become a lantern shape.

[0045] The steel wire rope 7 used in the present application has high elasticity, which is different from the use of other steel wire rope shock absorbing devices. The general steel wire rope shock absorbing device uses the steel wire rope to bear the horizontal force or the torsional force, and can only bear the horizontal force or the torsional force, and the force is single direction, while the present application uses the steel wire rope 7 to bear the longitudinal force, the horizontal force or the torsional force, and can also bear the composite force of multiple forces. Since the shock absorber is in the shape of a lantern as a whole, each single steel wire rope 7 is like a "bow" of a bow and arrow, so each single steel wire rope 7 has a shock absorbing function, and the lantern type shock absorber with multiple circumferentially uniformly arranged steel wire ropes 7 also has a strong shock absorbing function.

[0046] The universal connecting assembly 1 used in the present application is different from the function of the ball hinge used in general devices, and the ball hinge used in general devices basically only needs to bear the function of omnidirectional rotation, while the universal connecting assembly 1 used in the present application not only needs to bear the function of omnidirectional rotation, but also needs to bear the omnidirectional force and transmit the force to the steel wire rope 7.

[0047] The diameter, number of strands and rigidity of the steel wire rope 7 need to be determined according to the grade of vibration or the size of vibration energy, and the greater the diameter or the more the number of strands or the greater the rigidity of the steel wire rope 7, the higher the grade of shock absorption. The number of strands of the steel wire rope 7 needs to be at least three, and the more the number of strands of the steel wire rope 7, the higher the grade of shock absorption of the present application, and the size of the shock absorbing energy is in a linear relationship with the number of strands of the steel wire rope 7.

[0048] By changing one parameter or several parameters of the diameter, length, stiffness of the steel wire rope 7, or changing the number of strands of the steel wire rope 7, the overall stiffness of the lantern shock absorber can be changed to absorb different levels of shock energy.

[0049] The above embodiments are only illustrative of the present application and do not limit the protection scope thereof, and a person skilled in the art can also make changes to parts thereof, as long as the changes do not exceed the spirit and essence of the present application, and are within the protection scope of the present application.
