Description

Technical Field

[0001] The utility model relates to the field of bridge piers, in particular to a bridge pier support with shock absorption function. Background Art

[0002] Small and medium-span beam bridges are widely used in my country and are a crucial component of the country's increasingly developed road transportation network. Cylindrical piers are a common substructure for these bridges. These piers are bonded to the abutment, transferring loads from the bridge's superstructure to the foundation through the piers, ensuring the bridge remains operational. Support structures protect the piers.

[0003] According to a Chinese patent publication number CN108691266B, a multi-directional shock-absorbing device for bridge piers is disclosed. Under normal use, the shock-absorbing device maintains elasticity and does not affect the normal operation of the bridge piers. Under the action of seismic loads, the pier body will produce horizontal displacement. When the displacement is too large, the shock-absorbing device will yield while the outer support device remains elastic. The shock-absorbing device uses elastic-plastic deformation to perform reciprocating hysteresis energy dissipation, thereby dissipating seismic energy and reducing the horizontal displacement of the bridge pier.

[0004] In response to the above-mentioned disclosed patent content, a bendable elastic part is provided to play a shock-absorbing role, but the elastic part can only play a buffering and shock-absorbing role once, causing the elastic part to undergo more serious deformation. When the elastic part undergoes serious deformation, it may break, making it difficult for the elastic part to recover and continue to play a shock-absorbing role, thereby affecting the buffering and shock-absorbing and use effect of the support structure. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a bridge pier support with shock absorption, so as to solve the technical problem that when elastic parts are used for buffering and shock absorption, they may break and cause damage if severe deformation occurs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge pier support with shock absorption, comprising a pier, a steel plate is provided on the top of the pier, and a sleeve and a support sleeve are provided on the top of the steel plate respectively, a limiting ring and a second airbag ring are installed between the sleeve and the support sleeve, two fixing rings are provided on the inner wall of the sleeve, and a first airbag ring is provided between the two fixing rings, a plurality of shock-absorbing springs are also provided under the inner wall of the sleeve, and one end of the shock-absorbing spring is connected to the inner ring, the outer wall of the inner ring is provided with a plurality of pressure rods extending to the outside of the sleeve, and a push ring is installed at one end of the pressure rod.

[0007] By adopting the above technical solution, when the inner ring moves, it will squeeze the shock-absorbing spring, causing the shock-absorbing spring to be compressed, so as to play a buffering role.

[0008] Furthermore, a plurality of air tubes are provided between the first airbag ring and the second airbag ring.

[0009] By adopting the above technical solution, when the second airbag ring is compressed, the air inside it will enter the first airbag ring through the trachea, thereby causing the first airbag ring to expand.

[0010] Furthermore, one side of the push ring is connected to the inner wall of the second airbag ring, and the height of the second airbag ring is greater than that of the first airbag ring.

[0011] By adopting the above technical solution, the movement of the pressure rod can drive the push ring to move, and the push ring squeezes the second airbag ring, so that the second airbag ring is compressed.

[0012] Furthermore, a pier column is provided on the top of the pier, and fastening bolts extending into the interior of the pier are installed on the steel plate.

[0013] By adopting the above technical solution, it is convenient to install the steel plate on the pier by fastening bolts, thereby improving the stability of the steel plate.

[0014] Furthermore, a connecting ring is provided on the outer wall of the pier, and a plurality of elastic members are installed between the connecting ring and the sleeve ring.

[0015] By adopting the above technical solution, when the pier column is displaced horizontally, the elastic member will be squeezed, causing the elastic member to deform and thus play a shock-absorbing role.

[0016] Furthermore, a plurality of reinforcing ribs are installed on the outer wall of the support sleeve.

[0017] By adopting the above technical solution, the provision of reinforcing ribs can improve the compressive strength of the support sleeve and increase the service life of the support sleeve.

[0018] Furthermore, the elastic member is a C-shaped steel structure, and a plurality of the elastic members are distributed on the outer wall of the connecting ring in a ring array.

[0019] By adopting the above technical solution, the C-shaped steel structure is provided so that the elastic member can be deformed.

[0020] Furthermore, the inner ring fits against the outer wall of the pier.

[0021] By adopting the above technical solution, when the pier column is vibrated and horizontally displaced, the pier column will push the inner ring to move, and the movement of the inner ring will drive the pressure rod to move, so that the pressure rod will drive the push ring to move.

[0022] Furthermore, the first airbag ring is located on the outer wall of the pier, and four inner rings are provided, and the four inner rings form a circular ring shape.

[0023] By adopting the above technical solution, when the pier column undergoes horizontal displacement and contacts the first airbag ring, it will squeeze the first airbag ring, causing the first airbag ring to be compressed and at the same time protecting the pier column.

[0024] In summary, the present invention has the following beneficial effects:

[0025] The utility model is provided with a first airbag ring, a second airbag ring, an inner ring, a push ring, a pressure rod and an air tube. When the pier column undergoes horizontal displacement, it will push the inner ring to move, and the inner ring will push the push ring to move through the pressure rod and squeeze the second airbag ring, so that the second airbag ring is compressed, so as to have a buffering effect on the pier column. At this time, the air in the second airbag ring will enter the interior of the first airbag ring through the air tube, thereby causing the first airbag ring to expand. When the pier column contacts the first airbag ring, it will squeeze the first airbag ring, so that the first airbag ring is compressed, so as to cooperate with the second airbag ring to buffer the vibration of the pier column. The secondary buffering effect can improve the protective effect of the support. At the same time, the cooperation of the first airbag ring and the second airbag ring can avoid serious deformation of the elastic part, avoid damage to the elastic part, and thus increase the service life of the elastic part.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The following describes an embodiment of the present invention based on its overall structure.

[0034] Example 1:

[0035] A bridge pier support with shock absorption, such as Figure 1-Figure 5 As shown, it includes a pier 1, a steel plate 3 is provided on the top of the pier 1, and a ring 5 and a support sleeve 6 are respectively provided on the top of the steel plate 3, a limiting ring 11 and a second airbag ring 12 are installed between the ring 5 and the support sleeve 6, two fixing rings 7 are provided on the inner wall of the ring 5, and a first airbag ring 8 is provided between the two fixing rings 7, and a plurality of shock-absorbing springs 10 are also provided under the inner wall of the ring 5, and one end of the shock-absorbing spring 10 is connected to an inner ring 9, which will squeeze the shock-absorbing spring 10 when it moves, so that the shock-absorbing spring 10 is compressed to play a buffering role.

[0036] See Figure 1-Figure 4 There are multiple air tubes 17 between the first airbag ring 8 and the second airbag ring 12. When the second airbag ring 12 is compressed, the air inside it will enter the first airbag ring 8 through the air tube 17, thereby causing the first airbag ring 8 to expand. One side of the push ring 14 is connected to the inner wall of the second airbag ring 12. The height of the second airbag ring 12 is greater than the height of the first airbag ring 8. When the pressure rod 13 moves, it can drive the push ring 14 to move, and the push ring 14 squeezes the second airbag ring 12, so that the second airbag ring 12 is compressed. The outer wall of the inner ring 9 is provided with multiple pressure rods 13 that penetrate to the outside of the ring 5, and a push ring 14 is installed at one end of the pressure rod 13.

[0037] See Figure 1-Figure 3 A pier column 2 is provided on the top of the pier 1, and fastening bolts 4 extending to the inside of the pier 1 are installed on the steel plate 3, which makes it convenient to install the steel plate 3 on the pier 1 through the fastening bolts 4, thereby improving the stability of the steel plate 3. The inner ring 9 fits the outer wall of the pier column 2. When the pier column 2 is vibrated and horizontally displaced, the pier column 2 will push the inner ring 9 to move, and the inner ring 9 moves and drives the pressure rod 13 to move, so that the pressure rod 13 drives the push ring 14 to move. The first airbag ring 8 is located on the outer wall of the pier column 2. There are four inner rings 9, and the four inner rings 9 form a circular ring. When the pier column 2 is horizontally displaced and contacts the first airbag ring 8, it will squeeze the first airbag ring 8, so that the first airbag ring 8 is compressed, and at the same time it can protect the pier column 2.

[0038] Example 2:

[0039] On the basis of the above-mentioned embodiment 1, in order to improve the shock absorption effect of the supporting structure, the following structure is provided.

[0040] See Figure 1-Figure 3A connecting ring 16 is provided on the outer wall of the pier 2, and a plurality of elastic members 15 are installed between the connecting ring 16 and the collar 5. The elastic member 15 is a C-shaped steel structure. The plurality of elastic members 15 are distributed in a circular array on the outer wall of the connecting ring 16. The C-shaped steel structure is provided so that the elastic member 15 can be deformed. When the pier 2 is displaced horizontally, the elastic member 15 will be squeezed, causing the elastic member 15 to deform and thus play a shock-absorbing role.

[0041] Example 3:

[0042] On the basis of the above-mentioned embodiment 1, in order to improve the compressive strength of the support sleeve 6, the following structure is provided.

[0043] See Figure 1-Figure 3 The outer wall of the support sleeve 6 is installed with multiple reinforcing ribs 18. The setting of the reinforcing ribs 18 can improve the compressive strength of the support sleeve 6 and increase the service life of the support sleeve 6.

[0044] The working principle of the present invention is as follows: first, the arrangement of the sleeve ring 5 and the support sleeve 6 can protect the pier column 2. When the pier body is subjected to seismic load, the pier body will produce horizontal displacement. When the pier column 2 is displaced horizontally, it will push the inner ring 9 to move. The inner ring 9 pushes the push ring 14 to move through the pressure rod 13 and squeezes the second airbag ring 12, so that the second airbag ring 12 is compressed, so as to play a buffering role for the pier column 2. At this time, the air in the second airbag ring 12 will enter the first airbag ring 8 through the air tube 17, thereby causing the first airbag ring 8 to expand. When the pier column 2 contacts the first airbag ring 8, it will squeeze the first airbag ring 8, so that the first airbag ring 8 is compressed, so as to cooperate with the second airbag ring 12 to buffer the vibration of the pier column. At the same time, it will squeeze the elastic member 15, so that the elastic member 15 is deformed, so as to cooperate with the airbag ring to play a buffering role for the pier column 2 and prevent the elastic member 15 from being severely deformed and causing breakage and damage.
