DETAILED DESCRIPTION
[0054] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0055] Example 1
[0056] like Figure 1-Figure 3 As shown, this embodiment proposes a shock-absorbing and energy-absorbing anti-beam drop bearing, including an upper bearing plate 3, a flat slide plate 4, a sealing ring 5, a spherical crown lining plate 6, a spherical slide plate 7, a lower bearing plate 8, a spherical gasket 10, a pressure plate 11 and a U-shaped anti-beam drop device 12.
[0057] The upper support plate 3, the plane slide plate 4, the spherical cap lining plate 6, the spherical slide plate 7, and the lower support plate 8 are arranged in sequence from top to bottom. The plane slide plate 4 is fixed as a whole with the spherical cap lining plate 6 and contacts the upper support plate 3 to form a sliding pair, thereby realizing the horizontal displacement function of the support; the spherical slide plate 7 is fixed as a whole with the lower support plate 8 and forms a rotation pair with the spherical cap lining plate 6 to realize the rotation function of the support.
[0058] Sealing rings 5 are provided between the upper support plate 3 and the spherical cap lining plate 6 , and between the spherical cap lining plate 6 and the lower support plate 8 . The two sealing rings 5 are respectively located on the outer sides of the planar slide plate 4 and the spherical slide plate 7 .
[0059] The top of the upper support plate 3 is connected to the embedded steel plate 2 of the beam body through the upper anchor assembly 1, and the lower support plate 8 is connected to the pier through the lower anchor assembly 9, so as to transmit the horizontal force of the bridge.
[0060] The U-shaped anti-falling beam device 12 is arranged between the beam body embedded steel plate 2 and the lower support plate 8. In this embodiment, the U-shaped anti-falling beam device 12 is connected to the beam body embedded steel plate 2 and the lower support plate 8 respectively through connecting bolts 13.
[0061] The U-shaped anti-falling beam device 12 is provided with a strip hole 12-1, and the opening direction of the strip hole 12-1 is along the support and the direction of the bridge. The connecting bolt 13 is installed in the strip hole 12-1. Therefore, the U-shaped anti-falling beam device 12 can adapt to the displacement requirements of the bridge under normal circumstances. Under normal circumstances, the U-shaped anti-falling beam device 12 does not participate in the work.
[0062] A pressure plate 11 is provided between the U-shaped anti-falling beam device 12 and the connecting bolt 13, which is used to improve the force between the connecting bolt 13 and the U-shaped anti-falling beam device 12, improve the force surface reduction of the connecting bolt 13 caused by the strip hole 12-1, and at the same time improve the stress concentration problem of the U-shaped anti-falling beam device 12 at the connecting bolt 13, so that the U-shaped anti-falling beam device 12 is deformed along the entire edge of the pressure plate 11 during an earthquake, and the deformation and force are uniform. The pressure plate 11 is as Fig.13 and Fig.14 shown.
[0063] Furthermore, in order to prevent the U-shaped anti-falling beam device 12 from being continuously rubbed due to the deformation of the bridge and the rotation of the bearing during use, Fig.12As shown, a spherical washer 10 is arranged between the U-shaped anti-falling beam device 12 and the embedded steel plate 2 of the beam body, and between the pressure plate 11 and the connecting bolt 13. The two spherical washers 10 are arranged opposite to each other. When the beam body rotates and drives the support to rotate, the spherical washers 10 can adapt to the rotation of the upper structure to meet the normal rotation of the bridge. The spherical washers 10 are as shown in FIG. Fig.10 and Fig.11 shown.
[0064] like Figure 4-Figure 9 As shown, when the U-shaped anti-falling beam device 12 is arranged along the transverse direction of the bridge, it is set into a combination of a trapezoid and a long strip, and the strip hole 12-1 is opened along the support in the direction of the bridge; when the U-shaped anti-falling beam device 12 is arranged along the longitudinal direction of the bridge, it is set into a long strip, and the strip hole 12-1 is also opened along the support in the direction of the bridge.
[0065] The U-shaped anti-falling beam device 12 is a steel structure.
[0066] Furthermore, the U-shaped anti-falling beam device 12 has a U-shaped elevation and a rectangular, solid cylindrical or hollow circular tube cross section. Fig.15 The U-shaped anti-fall beam device 12 is shown with a solid cylindrical cross section. Fig.16 The U-shaped anti-fall beam device 12 is shown to have a hollow cylindrical cross-section, wherein the hollow portion thereof can be filled with other materials.
[0067] The utility model uses different U-shaped anti-falling beam devices 12 according to the structural form of the support, which can better adapt to the displacement, rotation and energy consumption function of the bridge under earthquake conditions.
[0068] Under normal circumstances, the bearing can meet the functional requirements of the bridge such as displacement, rotation, and horizontal bearing under normal circumstances; because the U-shaped anti-falling beam device 12 is provided with a strip hole 12-1, it can adapt to the displacement requirements of the bridge under normal circumstances, and the U-shaped anti-falling beam device 12 does not participate in the work. In the case of an earthquake, when the earthquake displacement exceeds the normal displacement, the U-shaped anti-falling beam device 12 starts to work, dissipating the earthquake energy through the plastic deformation of the steel parts, reducing the earthquake energy, and buffering the earthquake impact force. When the earthquake displacement reaches the designed buffering displacement of the U-shaped anti-falling beam device 12, the U-shaped anti-falling beam device 12 no longer moves, realizing the anti-falling beam function and preventing the bridge from falling.
[0069] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
