Description

Technical Field

[0001] The invention belongs to the technical field of building seismic isolation, and in particular relates to reinforcement, earthquake prevention and earthquake-resistant devices for buildings such as bridges. Background Art

[0002] Earthquakes are common and extremely destructive natural disasters, and they are also sudden and unpredictable. my country is a country with a high building density and high volume ratio. Earthquakes are common, with a wide distribution range, high frequency, and high intensity. Every earthquake with a high intensity will cause incalculable loss of life and property to the people. Therefore, doing earthquake prevention and earthquake resistance work in advance is an important research topic in the field of civil engineering.

[0003] In addition to earthquakes, other forms of vibration are also everywhere, such as air flow, vehicle movement, noise, etc., which can cause buildings to vibrate. These ubiquitous vibrations not only affect the service life of buildings, but also affect the accuracy of equipment in buildings. Therefore, it is even more urgent to develop equipment for building shock absorption.

[0004] At present, common shock-absorbing systems include laminated rubber pad isolation systems, combined isolation systems, sliding friction isolation systems, etc. Their essence is to isolate the building from ground vibrations to provide appropriate damping or increase the flexibility of the system, thereby achieving the effect of reducing vibration.

[0005] No matter what specific structure the damping medium shock absorber is refined into, such as "viscous damping", "friction sliding damping", "frequency modulation damping", "metal mild steel damping", "bridge fluid viscous damping", "viscous damping wall", etc., they all carry seismic waves in one direction, and the damping medium requires a direction control device. However, seismic waves are precisely unpredictable, and this type of shock absorber cannot fundamentally solve the seismic waves coming from different directions. Therefore, it is very necessary to develop a shock absorbing device that can simultaneously reduce or absorb seismic waves from different directions. Summary of the invention

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

[0007] A lantern-type building shock absorber comprises an elastic vibration reduction component and a universal connection component;

[0008] The universal connection assembly comprises a ball joint seat, a ball joint cover and a ball head, wherein the ball joint seat and the ball joint cover are detachably connected, a cavity in the shape of a spherical segment is formed between the ball joint seat and the ball joint cover, the ball head is universally hinged with the cavity, and a screw portion is connected to one side of the ball head;

[0009] The elastic vibration reduction assembly includes a bowl-shaped fastener, a bowl-shaped coupling and a plurality of steel ropes, the bowl-shaped fastener and the bowl-shaped coupling are detachably connected, the plurality of steel ropes are evenly arranged around the circumference, one end of the plurality of steel ropes is clamped between a group of bowl-shaped fasteners and the bowl-shaped coupling, and the other end of the plurality of steel ropes is clamped between another group of bowl-shaped fasteners and the bowl-shaped coupling;

[0010] The ball joint seats of the two universal connection components are respectively connected to the building foundation and the building body, and the screw rod parts of the two universal connection components are respectively connected to the two bowl-shaped connectors one by one.

[0011] Furthermore, the contour lines of the outer surface of the bowl-shaped fastener and the inner surface of the bowl-shaped connector are both in the shape of the major axis end lines of an ellipse, and the major axes and focal points of the contour lines of the outer surface of the bowl-shaped fastener and the inner surface of the bowl-shaped connector coincide with each other, several steel ropes are in the shape of the minor axis end lines of an ellipse, and the elastic vibration damping assembly is in the shape of an ellipsoid.

[0012] Furthermore, the outer surface of the bowl-shaped fastener and the inner surface of the bowl-shaped coupler are circumferentially provided with a plurality of grooves adapted to the steel wire ropes, and a plurality of steel wire ropes are clamped in the grooves of the bowl-shaped fastener and the bowl-shaped coupler in a one-to-one correspondence.

[0013] Furthermore, the number of the steel wire ropes is at least three.

[0014] Furthermore, the steel wire rope is formed by twisting seven steel wires.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention can be used for the reinforcement, earthquake prevention and earthquake resistance of buildings. According to different installation positions, the device can be installed horizontally, vertically or at any angle. Since the ball head is spherical, it can realize rotation in any direction in the cavity formed between the ball joint seat and the ball joint cover. Therefore, no matter which direction the building is vibrated, the vibration will be transmitted to the ball head through the ball joint seat. After the ball head receives the vibration, it will be transmitted to several steel wire ropes through the ball joint connector and the bowl-shaped fastener. At the same time, since several steel wire ropes are evenly distributed around the circumference, several steel wire ropes can absorb the vibration energy transmitted from any direction. The steel wire rope has high elasticity and can withstand longitudinal force, lateral force or torsional force, and can also withstand the composite force of multiple forces. Since the shock absorber is lantern-shaped as a whole, each individual steel wire rope is like the "bow" of a bow and arrow, so each individual steel wire rope has a shock absorbing function, and the lantern-type shock absorber with multiple strands of steel wire ropes evenly arranged around the circumference also has a powerful shock absorbing function.

[0031] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0032] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection is a non-detachable connection including but not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection and welding connection. The detachable connection includes but not limited to conventional detachable methods such as bolt connection, snap connection, pin connection and hinge connection. When the specific connection method is not clearly defined, it is assumed that at least one connection method can be found in the existing connection methods to achieve the function, and those skilled in the art can choose according to their needs. For example: welding connection is selected for fixed connection, and bolt connection is selected for detachable connection.

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings. The following embodiments are provided to explain the present invention, but the present invention is not limited to the following embodiments.

[0034] Example: Figures 1 to 13 As shown, a lantern-type building shock absorber comprises an elastic vibration reduction component 2 and a universal connection component 1;

[0035] The universal connection assembly 1 includes a ball joint seat 3, a ball joint cover 4 and a ball head 5. The ball joint seat 3 and the ball joint cover 4 are detachably connected. A spherical cavity is formed between the ball joint seat 3 and the ball joint cover 4. The ball head 5 is universally hinged with the cavity. A screw portion 10 is connected to one side of the ball head 5.

[0036] The elastic vibration reduction assembly 2 includes a bowl-shaped fastener 6, a bowl-shaped coupling 8 and a plurality of steel wire ropes 7. The bowl-shaped fastener 6 and the bowl-shaped coupling 8 are detachably connected. The plurality of steel wire ropes 7 are evenly arranged around the circumference. One end of the plurality of steel wire ropes 7 is clamped between a group of bowl-shaped fasteners 6 and bowl-shaped couplings 8, and the other ends of the plurality of steel wire ropes 7 are clamped between another group of bowl-shaped fasteners 6 and bowl-shaped couplings 8.

[0037] The ball joint seats 3 of the two universal connection components 1 are respectively connected to the building foundation and the building body, and the screw parts 10 of the two universal connection components 1 are respectively connected to the two bowl-shaped connectors 8 in a one-to-one correspondence.

[0038] The outer surface of the bowl-shaped fastener 6 and the inner surface contour lines of the bowl-shaped coupler 8 are both in the shape of the major axis end lines of an ellipse, and the major axes and focal points of the outer surface of the bowl-shaped fastener 6 and the inner surface contour lines of the bowl-shaped coupler 8 coincide with each other, a plurality of steel ropes 7 are all in the shape of the minor axis end lines of an ellipse, and the elastic vibration damping assembly 2 is in the shape of an ellipsoid.

[0039] 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 rope 7. A plurality of steel wire ropes 7 are clamped in the grooves 9 of the bowl-shaped fastener 6 and the bowl-shaped coupler 8 one by one. The bowl-shaped fastener 6 and the bowl-shaped coupler 8 clamp the steel wire rope 7 through bolts and make the steel wire rope 7, the bowl-shaped fastener 6 and the bowl-shaped coupler 8 a whole.

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

[0041] The steel wire rope 7 is formed by twisting seven steel wires.

[0042] The invention can be used for reinforcement, earthquake prevention and earthquake resistance of buildings. According to different installation positions, the device can be installed horizontally, vertically or at any angle.

[0043] Since the ball head 5 is spherical, it can realize rotation in any direction in the cavity formed between the ball joint seat 3 and the ball joint cover 4. Therefore, no matter which direction the building is subjected to vibration, the vibration will be transmitted to the ball head 5 through the ball joint seat 3. After the ball head 5 receives the vibration, it is transmitted to the plurality of steel ropes 7 through the ball joint connector 8 and the bowl-shaped fastener 6. At the same time, since the plurality of steel ropes 7 are evenly distributed around the circumference, the plurality of steel ropes 7 can absorb the vibration energy transmitted from any direction.

[0044] The two ends of the present invention are symmetrical. According to the installation dimensions at both ends and the additional deformation length of the steel wire rope 7, the natural extension length of the shock absorber is made greater than the basic length of the connection between the two ends of the shock absorber. Under the restriction of the ball joint seats 3 at both ends, the elastic vibration reduction assembly 2 will become the shape of a lantern.

[0045] The steel wire rope 7 used in the present invention has high elasticity, which is different from other steel wire rope shock absorbing devices in the use of steel wire rope. The general steel wire rope shock absorbing device uses the steel wire rope to withstand lateral force or torsional force, and can only withstand lateral force or torsional force, and the force borne is in a single direction, while the present invention uses the steel wire rope 7 to withstand longitudinal force, lateral force or torsional force, and can also withstand the composite force of multiple forces. Since the shock absorber is lantern-shaped as a whole, each individual steel wire rope 7 is like the "bow" of a bow and arrow, so each individual steel wire rope 7 has a shock absorbing function, and the lantern-shaped shock absorber with multiple strands of steel wire ropes 7 evenly arranged circumferentially also has a powerful shock absorbing function.

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

[0047] The diameter, number of strands, and stiffness of the steel wire rope 7 need to be determined according to the level of vibration or the magnitude of vibration energy. The larger the diameter, the more strands, or the greater the stiffness of the steel wire rope 7, the higher the level of shock absorption. The number of strands of the steel wire rope 7 needs to be at least three. The more strands of the steel wire rope 7, the higher the level of shock absorption of the present invention can be. The magnitude of shock absorption energy is linearly related to the number of strands of the steel wire rope 7.

[0048] By changing one or more parameters among the diameter, length and 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-type shock absorber can be changed to absorb vibration energy of different levels.

[0049] The above embodiments are merely exemplary descriptions of the present invention and do not limit its protection scope. Those skilled in the art may also make partial changes thereto, which are within the protection scope of the present invention as long as they do not exceed the spirit of the present invention.
