[0023] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: Reference Figure 1-Figure 3 A highway pile-plate structure with a pin-bolt rubber bearing comprises: a pile foundation 1, a rubber bearing 2, a pin 3 and a highway plate 4. Multiple groups of the pile foundations 1 are equidistantly buried in a soft base layer. The top of each pile foundation 1 is connected to a rubber bearing 2, and the top of the rubber bearing 2 is connected to a highway plate 4. The highway plate 4 and the upper part of the pin 3 are plugged in and matched, the rubber bearing 2 is plugged in and matched with the middle part of the pin 3, and the lower part of the pin 3 is threadedly connected to the top of the pile foundation 1. The diameter of the middle part of the pin 3 is smaller than the diameter of its upper and lower parts.

[0025] The principles and beneficial effects of the above scheme are:

[0026] Multiple groups of pile foundations 1 are buried in the soft base layer. The top of the pile foundation 1 is connected to the highway slab 4 through a rubber bearing 2. The upper part of the pin 3 is plugged into the highway slab 4, and the pin 3 and the rubber bearing 2 are plugged into each other. The lower part of the pin 3 is threadedly connected to the top of the pile foundation 1. The diameter of the middle part of the pin 3 is smaller than the diameter of its upper and lower parts. When the structure is not affected by an earthquake, the pin 3 anchors the highway slab 4 and bears the load together to ensure the structural rigidity. When an earthquake occurs, the pin 3 is subjected to shear force until the middle part of the pin 3 is damaged and sheared. After the pin 3 is sheared, the rubber bearing 2 continues to maintain the connection between the highway slab 4 and the pile foundation 1. By arranging the pin bolt 3 and the rubber bearing 2 to cooperate with each other to anchor the highway slab 4 and the pile foundation 1, the stability of the structure before an earthquake is increased. When the pin bolt 3 is sheared off by the shear force during the earthquake, the rubber bearing 2 absorbs most of the vibration. After the pin bolt 3 is sheared off, the highway slab 4 and the pile foundation 1 are continued to be connected through the rubber bearing 2, ensuring that the highway slab 4 will not fall off after the earthquake, thereby improving the stability of the structure; the diameter of the middle part of the pin bolt 3 is smaller than the diameter of its upper and lower parts. When an earthquake occurs, the middle part of the pin bolt 3 can guide the shearing direction and prevent the rubber bearing 2 from being damaged when the pin bolt 3 is sheared off.

[0027] Example 2: Reference Figure 1-Figure 3 The highway plate 4 includes: a highway plate iron plate 5 and a plate body 6. The top of the rubber bearing 2 is connected to the bottom end of the highway plate iron plate 5, and the top of the highway plate iron plate 5 is connected to the plate body 6. A second mounting hole 16 is opened on the plate body 6. The bottom end of the second mounting hole 16 is coaxially connected with a through hole 17. A second through hole 18 is opened on the highway plate iron plate 5. The through hole 17 and the second through hole 18 are both plugged into the upper part of the pin 3.

[0028] The principles and beneficial effects of the above scheme are:

[0029] A through hole 17 is opened on the plate body 6, and a second through hole 18 is opened on the highway plate iron plate 5. The through hole 17 and the second through hole 18 are both plugged into the upper part of the pin 3. The setting of the through hole 17 and the second through hole 18 increases the stability of the pin 3.

[0030] Example 3: Reference Figure 1-Figure 3 The rubber bearing 2 includes: a rubber block 7, an upper top plate 8 and a lower top plate 9. The bottom end of the highway iron plate 5 is connected to the upper top plate 8, and the bottom end of the upper top plate 8 is connected to the lower top plate 9 through the rubber block 7.

[0031] The upper top plate 8 is provided with a third through hole 19 , the rubber block 7 is provided with a fourth through hole 20 , and the lower top plate 9 is provided with a fifth through hole 21 . The third through hole 19 , the fourth through hole 20 and the fifth through hole 21 are all plugged into and matched with the middle portion of the pin 3 .

[0032] The principles and beneficial effects of the above scheme are:

[0033] The highway plate iron plate 5 inside the highway plate 4 is connected to the upper top plate 8, which increases the stability of the connection between the rubber bearing 2 and the highway plate 4 and reduces the difficulty of installing the rubber bearing 2 and the highway plate 4; the upper top plate 8 and the lower top plate 9 are respectively located at the top and bottom ends of the rubber block 7, which increases the wear resistance of both ends of the rubber block 7. At the same time, the upper top plate 8 and the lower top plate 9 can evenly distribute the load on the rubber block 7, thereby improving the service life of the rubber block 7. The through hole three 19, the through hole four 20 and the through hole five 21 are all plugged into the middle part of the pin bolt 3. The through hole three 19 and the through hole five 21 fix the middle part of the pin bolt 3, and the through hole four 20 covers the middle part of the pin bolt 3, further increasing the stability of the pin bolt 3 when anchoring the highway plate 4 and the pile foundation 1 before the earthquake.

[0034] Example 4: Reference Figure 1-Figure 3 The pile foundation 1 includes: a pile top plate 10, the bottom end of the lower top plate 9 is connected to the top of the pile top plate 10, and a screw hole 22 is opened on the pile top plate 10, which is threadedly connected to the threaded section at the bottom of the pin 3.

[0035] The pile foundation 1 further includes a pile column 11 . The bottom end of the pile column top plate 10 is connected to the top end of the pile column 11 . A mounting hole 23 is formed at the top end of the pile column 11 . The mounting hole 23 is plugged into the bottom end of the pin 3 .

[0036] The principles and beneficial effects of the above scheme are:

The screw hole 22 on the pile top plate 10 is concentric with the mounting hole 23 and the through hole 5 21. The threaded section at the lower part of the pin 3 can be threadedly connected with the screw hole 22 to ensure the stability of the pin 3 in the vertical direction after installation. The mounting hole 23 can accommodate the bottom end of the pin 3. Under the premise of ensuring that the length of the threaded connection between the threaded section at the lower part of the pin 3 and the top plate of the pile top plate 10 is sufficient to prevent the pin 3 from falling off, the mounting hole 23 can guide the bottom end of the pin 3 during installation, reduce the thickness of the pile top plate 10, improve the rationality of the structural design, and reduce the cost of manufacturing the pile top plate 10.

[0038] The upper top plate 8, the lower top plate 9 and the pile top plate 10 are all made of steel.

[0039] Example 5: Reference Figure 1-Figure 3 The top of the pin 3 is coaxially provided with a sealing disk 12, the side wall of the sealing disk 12 is sealed with the inner wall of the second mounting hole 16, and the bottom surface of the sealing disk 12 is in contact with the bottom wall of the second mounting hole 16.

[0040] The principles and beneficial effects of the above scheme are:

[0041] A second mounting hole 16 is provided on the plate body 6. The second mounting hole 16 is concentric with the through hole 17. The bottom end of the second mounting hole 16 is coaxial with the through hole 17. A sealing disk 12 is coaxially installed on the top end of the pin 3. The sealing disk 12 seals the second mounting hole 16 to prevent rainwater or debris from entering the through hole after the pin 3 is installed.

[0042] Example 6: Reference Figure 1-Figure 3 The top surface of the sealing disk 12 is coaxially provided with a nut 13 , and the nut 13 is arranged in the second mounting hole 16 .

[0043] The principles and beneficial effects of the above scheme are:

[0044] A nut 13 is coaxially mounted on the top surface of the sealing disk 12 , and the operator can use a hexagonal sleeve or a polygonal sleeve to screw the pin 3 , making it easy to install and remove the pin 3 .

[0045] Example 7: Reference Figure 1-Figure 3 The top of the threaded section at the bottom of the pin 3 is provided with a chamfer 14.

[0046] The bottom end of the threaded section at the lower part of the pin 3 is provided with a chamfer 15 .

[0047] The principles and beneficial effects of the above scheme are:

[0048] When the pin 3 is disassembled, the chamfer 14 can prevent the through hole 4 from being scratched by the threaded section at the bottom of the pin 3. When the pin 3 is installed, the chamfer 15 can prevent the through hole 4 20 from being scratched by the threaded section at the bottom of the pin 3, thereby increasing the service life of the rubber block 7.
