Technical Field

[0001] This application relates to the technical field of bridge bearings, and particularly to a bridge bearing protection device. Background Art

[0002] A bridge bearing is an important structural component connecting the upper and lower structures of a bridge. It is located between the bridge and the cushion stone and can reliably transfer the loads and deformations (displacements and rotations) borne by the upper structure of the bridge to the lower structure of the bridge. It is an important load-transfer device for bridges. There are two types: fixed bearings and movable bearings.

[0020] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0021] In the description of this application, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are all based on the attached Figure 1 , and are only for the convenience of describing this application 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 to this application.

[0022] As Figure 1-2 shown, a bridge bearing protection device includes a rubber cylinder 5 and two sets of circumfixing components for fixing both ends of the rubber cylinder 5; the circumfixing component includes a mounting plate 1 and a connecting ear 3. There are two mounting plates 1, and the two ends of one mounting plate 1 are detachably connected to the two ends of the other mounting plate 1 one by one. After the two mounting plates 1 are connected, they are fixed to the connecting plate of the bearing in a rectangular or circular shape.

[0023] Specifically, both ends of the rubber cylinder 5 can be fastened to the two connecting plates of the bridge bearing by two sets of fastening components. Each fastening component includes two mounting plates 1 that are detachably connected, which is convenient for assembly and can adapt to the shape of the connecting plate to fasten the rubber cylinder 5 to the bridge bearing.

[0024] Furthermore, a pressure strip 2 is fixedly connected along the inner side of the mounting plate 1.

[0025] Specifically, the pressure strip 2 arranged along the inner side of the mounting plate 1 can further press the rubber cylinder 5 on the bridge bearing, increasing the sealing performance and reducing the corrosion of the bridge bearing.

[0026] Furthermore, connecting ears 3 are integrally formed at both ends of the mounting plate 1 and are connected by bolts 4. The bolts 4 fasten the connecting ears 3 at both ends of the two mounting plates 1 together, enabling the mounting plates 1 to be surrounded and installed on the connecting plate of the bridge bearing.

[0027] Furthermore, flanges 6 that turn outwards are provided at both ends of the rubber cylinder 5. The flanges 6 are fastened to the outside of the mounting plate 1 by pressing plates 7, and the pressing plates 7 are fastened to the mounting plate 1 by fasteners 8.

[0028] Specifically, both ends of the rubber cylinder 5 have flanges 6 that turn outwards. After the fastening components fasten both ends of the rubber cylinder 5, the outwards-turned flanges 6 are pressed against the outside of the mounting plate 1 through the flanges 6, and then the fasteners 8 are used to fasten the pressing plates 7 to fasten the flanges 6, further preventing both ends of the rubber cylinder 5 from falling off.

[0029] Furthermore, the mounting plate 1 is semi-circular or "U"-shaped, and the two mounting plates 1 of the fastening component form a circle or a rectangle to adapt to the shape of the connecting plate of the bridge bearing.

[0030] Furthermore, a salt spray resistant coating is provided on the outside of the rubber cylinder 5 to increase the salt spray resistance performance, improve the service life, and increase the protection life.

[0031] Furthermore, the rubber cylinder 5 is a cylinder with both ends open to fit the connecting plates of the bridge bearing. The two connecting plates of the bridge bearing are located at the open ends of both ends of the rubber cylinder 5, and other components are located inside the rubber cylinder 5. The rubber cylinder 5 protects the bridge bearing through sealing to reduce corrosion.

[0032] In the above structure, one end of the rubber cylinder 5 is fixed on the lower plate of the support by combining and surrounding it with two pressing strips 2, and the other end of the rubber cylinder 5 is fixed on the upper plate of the support by combining and surrounding it with two pressing strips 2. The two pressing strips 2 are fixedly connected together by tightening the connecting ear 3 with bolts 4. At the same time, the pressing strip 2 inside the mounting plate 1 presses the rubber cylinder 5 on the support to ensure the sealing performance. Then, the flanges 6 at both ends of the rubber cylinder 5 are turned outwards, and the pressing plate 7 is pressed against the outside of the mounting plate 1. Then, the pressing plate 7 is fastened to the mounting plate 1 by using the fastener 8, so that the pressing plate 7 presses the flange 6 to prevent it from falling off. Through the above operations, protection can be formed outside the bridge support to prevent the salt spray from damaging the support. At the same time, the flexibility of the rubber cylinder 5 will not affect the support of the bridge by the support.

[0033] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed.
