[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.
[0025] Figure 1 This is one of the structural schematic diagrams of the slope-type bearing of a highway bridge with a long longitudinal slope according to the preferred embodiment of the utility model; Figure 2 This is the second structural schematic diagram of the slope-type support of a highway bridge with a long longitudinal slope according to the preferred embodiment of the utility model.
[0026] like Figure 1 and Figure 2As shown, the slope bearing of a highway bridge with a long longitudinal slope in this embodiment is used to be arranged on a bridge pier 100, and includes an anchoring assembly 200, a bearing lower seat plate 300, an intermediate plate group 400 and a slope upper bearing plate 500. The bearing lower seat plate 300 is fixedly connected to the bridge pier 100 through the anchoring assembly 200, and the bearing lower seat plate 300 is connected to and supports the slope upper bearing plate 500 through the intermediate plate group 400; the slope upper bearing plate 500 is quadrilateral, and has a first side surface 501 and a second side surface 502 arranged along the longitudinal direction of the bridge, and has a third side surface 503 and a fourth side surface 504 perpendicular to the longitudinal direction of the bridge, and the height dimension of the first side surface 501 and the height dimension of the second side surface 502 increase in the same direction, and at least one of the height dimension of the third side surface 503 and / or the height dimension of the fourth side surface 504 is adaptively gradient. The utility model discloses a slope-type bearing for a highway bridge with a long longitudinal slope. The middle plate group 400 connects the bearing lower seat plate 300 and the slope-type upper bearing plate 500, which can more evenly transfer the load of the upper structure to the bridge pier 100 and reduce local stress concentration. The anchoring assembly 200 fixes the bearing lower seat plate 300 to the bridge pier 100, provides a stable anchoring effect, and enhances the overall stability of the bridge structure. The slope-type upper bearing plate 500 has a quadrilateral design, in which the height dimensions of the first side surface 501 and the second side surface 502 increase gradually, and at least one of the height dimensions of the third side surface 503 and the fourth side surface 504 is adaptively gradient. It can be easily identified by the increase in the height dimensions of the first side surface 501 and the second side surface 502 along the same direction. The composite slope direction of the slope bearing allows the bearing to be installed correctly, while enabling the bearing to adapt to the longitudinal slope of the bridge, ensuring the stability and continuity of the bridge in the slope change area; the adaptive gradient side design helps to reduce the deformation of the bridge under different slopes, maintain the geometric shape of the bridge and driving comfort; the design of the slope bearing takes into account the stress characteristics of the bridge on the longitudinal slope, which helps to improve the durability and service life of the bearing; when natural disasters such as earthquakes occur, the design of the slope bearing helps to absorb and disperse seismic energy and improve the seismic performance of the bridge; the design of the slope bearing of the highway bridge with long longitudinal slope comprehensively considers multiple factors such as the stability of the bridge structure, load transfer and durability, so as to adapt to the special needs of highway bridges in the longitudinal slope area.
[0027] like Figure 2As shown, in this embodiment, the height dimension of the third side 503 is adaptively gradient, and the height dimension of the first side 501 and the height dimension of the second side 502 both increase in the direction away from the third side 503. The bearing is allowed to adapt to the longitudinal slope change of the bridge, ensuring that the bearing can match the slope of the bridge, thereby ensuring that the horizontal and vertical forces of the bridge structure can be evenly transferred to the pier 100; as the height dimensions of the first side 501 and the second side 502 increase, the load can be more effectively transferred from the bridge to the bearing, and then from the bearing to the pier 100, reducing local stress concentration; the adaptive gradient height dimension helps to improve the stability of the bearing and the entire bridge structure, especially on bridges with larger slopes; by rationally designing the change in side height, the bearing can be reduced due to eccentric force or excessive shear force. The design of the bearings, which adapt to the longitudinal slope of the bridge, helps reduce material fatigue caused by uneven stress, thereby extending the service life of the bearings. The reasonable side height design simplifies the construction process and facilitates the inspection and maintenance of the bearings. The adaptive design helps reduce the bumpy feeling of vehicles on the bridge, improving driving stability and comfort. The height adaptability of the bearings helps to cope with the expansion and contraction of the bridge caused by changes in temperature and humidity, maintaining the normal use of the bridge. In the event of natural disasters such as earthquakes, this design helps the bearings absorb and disperse seismic energy, improving the seismic performance of the bridge. By adapting to the longitudinal slope of the bridge and the load transfer requirements, the safety, stability and durability of the bridge structure are improved, while also improving the driving experience.
[0028] like Figure 2As shown, in this embodiment, the corner edge between the third side surface 503 and the first side surface 501 is the edge with the smallest height, and the slope of the upper edge of the first side surface 501 from the third side surface 503 to the fourth side surface 504 is i1%. The i1% slope matches the longitudinal slope of the bridge bottom surface, allowing the bearings to adapt to the longitudinal slope of the bridge, enabling them to better withstand and distribute forces on the bridge structure along the slope, helping to improve the durability of the bearings and extend their service life. The slope design helps provide better adaptability and stability between the bearings and the bridge structure, especially on bridges with larger slopes. It can reduce the bumpy feeling when vehicles pass through the bridge, improving driving smoothness and comfort. The minimum height edge serves as the corner edge, which helps achieve more uniform stress distribution in the bearings and reduces potential damage caused by stress concentration. The clear slope and minimum height edge design facilitates precise installation during construction and simplifies subsequent maintenance. The bearing design takes into account the expansion and contraction of the bridge caused by temperature changes. The slope design helps the bearings adapt to this expansion and contraction, reducing structural problems caused by temperature changes. In the event of natural disasters such as earthquakes, it helps the bearings better absorb and disperse vibration, improving the seismic performance of the bridge. By considering factors such as the longitudinal slope of the bridge, stress distribution, and temperature changes, the performance of the bridge bearings and the overall safety, stability, and durability of the bridge are improved. Optionally, the slope i1% is not greater than 4%. Optionally, at the longitudinal slope position of the bridge approach, the slope i1% is not greater than 5%.
[0029] like Figure 2As shown, in this embodiment, the slope of the upper edge of the third side 503 from the first side 501 to the second side 502 is i2%. The slope i2% is a slope that matches the transverse direction of the bottom surface of the bridge. Taking into account the longitudinal slope characteristics of the bridge, the longitudinal slope of the bridge is adapted to ensure the rationality of load transfer through the gradual increase in the height dimensions of the first side 501 and the second side 502, as well as the adaptive gradual change in the height dimensions of the third side 503 and the fourth side 504; the adaptive height dimension gradient helps to achieve a more uniform load distribution on the support, improve the stability of the entire bridge structure, and the uniform load distribution helps to reduce the wear and aging of the support material and extend the service life of the support; the clear slope and height dimension design helps construction personnel to carry out precise installation according to the design requirements and simplify the later Maintenance work; the slope design helps reduce vehicle bumps on the bridge, improving driving smoothness and comfort; the bearing design takes into account the expansion and contraction of the bridge caused by temperature and humidity changes, adapting to these environmental changes and maintaining the normal operation of the bridge. In the event of natural disasters such as earthquakes, this design helps the bearings better absorb and disperse vibrations, improving the bridge's seismic performance. The bridge's longitudinal slope adaptability, load transfer, drainage performance, structural stability, durability, construction and maintenance ease, and driving comfort are comprehensively considered to meet the special needs of highway bridges with long longitudinal slopes. The slope i2% can optionally range from 1.5% to 3%.
