[0021] As shown in Figure 1 , a support reinforcement retrofit device includes a U-shaped steel plate 1, a pier top steel plate 2, a pair of spherical supports 3, beam body anchor bolts 4, and pier top anchor bolts 5. The U-shaped steel plate 1 is arranged on the outer surface of the beam body, and the U-shaped steel plate 1 surrounds the bottom surface and the two side surfaces of the beam body. The spherical supports 3 are arranged on the inner side of the two side edges of the bottom surface of the U-shaped steel plate 1. The pier top steel plate 2 is arranged on the upper surface of the pier top. The upper surface of the spherical support 3 is connected to the bottom surface of the U-shaped steel plate 1, and the lower surface of the spherical support 3 is connected to the top surface of the pier top steel plate 2. The pier top steel plate 2 is connected to the pier top through the pier top anchor bolts 5, which are vertically connected. The U-shaped steel plate 1 is connected to the beam body through the beam body anchor bolts 4, which are arranged horizontally.
[0022] As shown in Figure 2 , the spherical support 3 includes an upper support 31, a spherical crown lining plate 32, and a lower support 33. The upper support 31 is a block structure and is inserted into the bottom surface of the U-shaped steel plate 1. The upper support 31 is arranged on the upper surface of the middle part of the spherical crown lining plate 32. The spherical crown lining plate 32 is a structure without a maximum diameter ball. The spherical surface of the spherical crown lining plate 32 is the lower surface. The maximum horizontal length of the upper support 31 is smaller than the diameter of the upper surface of the spherical crown lining plate 32. The lower support 33 is a block body with a groove on the surface matched with the lower surface of the spherical crown lining plate 32. The lower support 33 is arranged on the upper surface of the pier top steel plate 2.
[0023] A friction pair is arranged between the upper support 31 and the spherical crown lining plate 32, and between the spherical crown lining plate 32 and the lower support 33.
[0024] When the height from the pier, abutment to the beam bottom is small, and the entire spherical support cannot be installed, the original beam bottom embedded part and the upper support plate of the spherical support are removed. A protrusion is arranged on the spherical crown. A U-shaped steel plate is arranged on the beam, and a groove is opened on the bottom surface of the U-shaped steel plate to connect with the protrusion of the spherical crown, so that the resistance to horizontal force performance is greatly improved. The U-shaped steel plate and the two side surfaces of the beam body are connected by anchor bolts, which enhances the stability of the overall structure. When the bridge has a falling tendency due to earthquakes or external disasters, the connection of the U-shaped steel plate and the spherical crown limits the movement of the beam body, so that it will not fall.

[0026] A friction pair is arranged between the upper support 31 and the spherical crown lining plate 32 and between the spherical crown lining plate 32 and the lower support 33.
[0027] When the height of the pier and abutment to the beam bottom is sufficient to install the whole spherical support, the U-shaped steel plate is arranged on the beam, the threaded holes are drilled on the bottom of the U-shaped steel plate, and the spherical support is fixed on the beam bottom through bolt connection. The U-shaped steel plate and the two side surfaces of the beam body are connected through anchor bolts to enhance the stability of the whole structure. When the bridge has a falling tendency due to an earthquake or external disasters, the connection between the U-shaped steel plate and the spherical support limits the movement of the beam body so that it will not fall.
