[0002] A bridge pier is a structure that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation. The abutment is located at both ends of the bridge. The bridge pier is located between the two abutments. The function of the bridge pier is to support the bridge span structure. The intermediate support structure of a multi-span bridge is called a bridge pier. Bridge piers are divided into solid piers, column piers, bent caps, etc.; existing bridge piers mainly consist of a pier cap and a pier body. The abutment mainly consists of a pier cap and a abutment body. The function of the pier cap is to evenly disperse the large and concentrated force transmitted by the bridge span support to the pier body and the abutment body; Most bridge construction is achieved by splicing sections of bridge segments. The head end of one bridge segment and the tail end of another bridge segment are placed on the pier cap to achieve splicing;

[0003] However, when a minor earthquake occurs on the ground under the pier cap, it will cause the bridge segment to move left and right, front and back. In severe cases, the bridge segment will fall, causing a major accident.

[0004] In view of the above problems, the present utility model is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a pier cap structure for earthquake resistance and preventing beam boxes from falling, which is used to solve the problems mentioned in the background technique.

[0006] To solve the above technical problems, the present utility model provides the following technical solutions.

[0007] The present utility model provides a pier cap structure for earthquake resistance and preventing beam boxes from falling, including a pier cap body, a support beam and a second cushion block. A first water trough is arranged at the center of the upper surface of the pier cap body, and the first water trough is arranged along the front-back direction of the pier cap body. Second water troughs are vertically arranged at the center positions of the front and back of the pier cap body. Both ends of the first water trough are respectively communicated with the tops of the two second water troughs;

[0008] Two side stoppers are symmetrically arranged at the left and right positions of the upper surface of the pier cap body. The side stoppers are perpendicular to the upper surface of the pier cap body. The surface of the side stopper close to the first water trough is flat, and the two left and right side stoppers are aligned;

[0009] Two first cushion blocks are also symmetrically arranged at the left and right positions of the upper surface of the pier cap body. The first cushion blocks are located between the side stoppers and the first water trough;

[0010] The support beams are arranged on both sides of the front and back of the pier cap body, the second cushion blocks are arranged on the upper surface of the support beams, and the upper surfaces of the second cushion blocks and the first cushion blocks are at the same vertical height.

[0011] Preferably, the front end and the rear end of the first water tank respectively penetrate through the front and the back of the pier cap body, the upper end of the second water tank penetrates through the upper surface of the pier cap body, the lower end of the second water tank penetrates through the lower surface of the pier cap body, and the width of the second water tank is smaller than that of the first water tank.

[0012] Preferably, the support beam is in an inverted "L" shape, the vertical part of the support beam is installed on the front and back of the pier cap body through the first bolts, a backing plate is arranged on the upper surface of the horizontal part of the support beam, and the backing plate is fixed on the lower surface of the second cushion block through the second bolts.

[0013] Preferably, a support rod is arranged between the lower end of the vertical part and the front end of the horizontal part of the support beam, and the support rod is in an inclined shape.

[0014] Preferably, two support beams are arranged on the left side of the front, the right side of the front, the left side of the back, and the right side of the back of the pier cap body.

[0015] Preferably, the edge of the first cushion block is close to the first water tank.

[0016] Preferably, the width of the upper surface of the pier cap body gradually decreases from the upper surface to the lower surface.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The front end of one bridge section and the tail end of another bridge section are installed on the pier cap body. When the ground under the pier cap body shakes, in the left-right direction, there are two side blocks symmetrically arranged, and the side blocks play a limiting role on the front end and the tail end of the bridge section, so that the two bridge sections will not fall from the left side and the right side of the pier cap body;

[0019] The two second cushion blocks on the front and the two second cushion blocks on the back increase the support distance of the pier cap body in the front-back direction. When the two bridge sections shake back and forth, it is very difficult for the bridge sections to fall from the two second cushion blocks on the front and the two second cushion blocks on the back;

[0020] On the premise that the thickness of the pier cap body is not increased, two second cushion blocks are added at the front and the back, so that the front-back support distance is increased.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0028] As Figures 1-3 shown, a pier cap structure for earthquake-resistant and anti-beam box dropping includes a pier cap body 1, a support beam 2 and a second cushion block 23. A first water trough 11 is provided in the center of the upper surface of the pier cap body 1, and the first water trough 11 is arranged along the front-rear direction of the pier cap body 1. Second water troughs 12 are vertically arranged at the central positions of the front and rear of the pier cap body 1. Both ends of the first water trough 11 are respectively connected to the tops of the two second water troughs 12. When there is accumulated water at the junction position of the two bridge sections 3, the accumulated water can be drained through the first water trough 11 and the second water trough 12, preventing rainwater from accumulating on the pier cap body 1;

[0029] On the upper surface of the pier cap body 1, two side stoppers 13 are symmetrically arranged at the left and right positions. The side stoppers 13 are perpendicular to the upper surface of the pier cap body 1. The surface of the side stopper 13 close to the first water tank 11 is flat. The two left and right side stoppers 13 are aligned. The two side stoppers 13 play a role in limiting the left and right positions of the two bridge sections 3, preventing the junction position of the two bridge sections 3 from falling from the left and right sides of the pier cap body 1;

[0030] On the upper surface of the pier cap body 1, two first cushion blocks 14 are also symmetrically arranged at the left and right positions. The first cushion blocks 14 are located between the side stoppers 13 and the first water tank 11. The first cushion blocks 14 are made of materials with buffering performance;

[0031] The support beams 2 are arranged on both the front and back sides of the two sides of the pier cap body 1. The second cushion blocks 23 are arranged on the upper surfaces of the support beams 2. The upper surfaces of the second cushion blocks 23 are at the same vertical height as the upper surfaces of the first cushion blocks 14, or the second cushion blocks 23 are slightly lower than the first cushion blocks 14 in the vertical height. That is, the first cushion blocks 14 play a supporting role, and the second cushion blocks 23 mainly increase the distance of the pier cap body 1 in the front and back directions, preventing the two bridge sections 3 from falling directly after leaving the first cushion blocks 14.

[0032] The front end and the rear end of the first water tank 11 respectively penetrate through the front and back surfaces of the pier cap body 1. The upper end of the second water tank 12 penetrates through the upper surface of the pier cap body 1, and the lower end of the second water tank 12 penetrates through the lower surface of the pier cap body 1. The width of the second water tank 12 is smaller than the width of the first water tank 11.

[0033] The support beam 2 is in an inverted "L" shape. The vertical part of the support beam 2 is installed on the front and back surfaces of the pier cap body 1 through the first bolt 20. The upper surface of the horizontal part of the support beam 2 is provided with a backing plate 22, and the backing plate 22 is fixed to the lower surface of the second cushion block 23 through the second bolt 24.

[0034] A support rod 21 is arranged between the lower end of the vertical part and the front end of the horizontal part of the support beam 2. The support rod 21 is in an inclined shape.

[0035] Two support beams 2 are arranged on the left side of the front, the right side of the front, the left side of the back, and the right side of the back of the pier cap body 1.

[0036] The edge of the first cushion block 14 is close to the first water tank 11; the width of the upper surface of the pier cap body 1 gradually decreases from the upper surface to the lower surface.

[0037] In summary: The front end of one bridge section 3 and the tail end of another bridge section 3 are installed on the pier cap body 1. When the ground under the pier cap body 1 shakes, in the left and right directions, there are two symmetrically arranged side stoppers 13. The side stoppers 13 play a role in limiting the front end and the tail end of the bridge section 3, so that the two bridge sections 3 will not fall from the left and right sides of the pier cap body 1;

[0038] The supporting distance of the pier cap body that increases in the front-back direction due to the two second cushion blocks 23 on the front side and the two second cushion blocks 23 on the back side makes it difficult for the bridge section 3 to fall off the two second cushion blocks 23 on the front side and the two second cushion blocks 23 on the back side when the two bridge sections 3 sway back and forth;

[0039] On the premise that the thickness of the pier cap body 1 does not increase, adding the two second cushion blocks 23 at the front and back increases the front-back supporting distance. In this way, when the ground shakes, the front end of one bridge section 3 and the tail end of another bridge section 3 are also less likely to fall off the second cushion blocks 23;

[0040] The first cushion block 14 is made of a material with buffering performance. In this way, when the vehicle passes through the junction position of the two bridge sections 3, the first cushion block 14 can reduce the impact force on the pier cap body 1, and the entire pier cap structure is more stable.

[0041] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
