Problems solved by technology

[0007] 1) The size of the support is too large;
[0008] 2) It is difficult to set the stiffness of the horizontal direction of the support;
[0009] 3) Due to the lack of vertical rigidity of urban bridges due to the use of rubber bearings, traffic vibration pollution is caused;
[0010] 4) A certain pier or several piers of a bridge are seriously damaged, while other piers are not damaged, and the force cannot be coordinated
[0011] The design idea of ​​the existing bearing is to combine the conventional function of the bearing a

Embodiment 1

[0047] Such as figure 2 with image 3 As shown, the embodiment of the present invention provides a bridge support device installed between the bridge pier 1 and the superstructure 5 . The device includes: a supporting base 2 , a vibration-isolation bearing 3 and an installation base 4 .

[0048] Pier 1 is at the bottom of the bridge and provides support for the entire bridge. The piers 1 support the superstructure 5 of the bridge by means of supporting means.

[0049]The upper end of the bridge pier is provided with a boss for installing the support support 2, one end of the support support 2 is fixed on the above-mentioned boss, and the other end is fixedly connected with the superstructure 5 . The support base 2 is used to undertake conventional functions, and has the functions of bearing the vertical load, rotation and horizontal movement of the bridge superstructure. During an earthquake, the anti-pull function of the support device belongs to the vertical load, which...

Embodiment 2

[0060] Such as Figure 5 with Image 6 As shown, the difference between embodiment 2 and embodiment 1 is that the mounting base 4 is fixed above the pier 1, the mounting base 4 is located in the middle of the two supporting bases 2, and the shock-isolation bearing 3 is fixed on the side of the mounting base 4 on the upper surface. Image 6 The dotted line in represents the superstructure of the bridge, and one end of the isolation bearing 3 is fixedly connected to the lower surface of the superstructure of the bridge.

[0061] Such a design can make the shock-isolation support 3 bear a small part of the vertical load, and minimize the vibration caused by traffic. However, the main function of the shock-isolation bearing 3 is still to bear horizontal loads.

[0062] On the other hand, an embodiment of the present invention provides a method for installing the above device, including steps:

[0063] 1. Install one end of the supporting support above the pier, and connect the...

Embodiment 3

[0067] Such as Figure 7 As shown, the embodiment of the present invention provides a bridge supporting device. The difference between this device and Embodiment 1 is that the mounting base 4 and the supporting base 2 are arranged at intervals, and the left and right sides of the mounting base 4 in the middle are equipped with shock-absorbing bearings 3 . Such a structure is more suitable for bridges located in high-earthquake areas.

[0068] On the other hand, an embodiment of the present invention provides a method for installing the above device, including steps:

[0069] 1. Install one end of the supporting support above the pier, and connect the other end to the superstructure.

[0070] 2. Install the mounting seat on the top of the bridge pier, and arrange the mounting seat and the supporting support at intervals.

[0071] 3. Install one end of the shock-isolation support on the side surface of the mounting base, and connect the other end to the upper structure.

Abstract

The invention discloses a bridge supporting device, an installation method thereof and a bridge supporting system. The bridge supporting device comprises supporting bearings, seismic isolation bearings and installation seats, wherein the supporting bearings are fixed on a bridge pier and fixedly connected to an upper structure; the installation seats are fixed on the bridge pier and positioned onthe sides of the supporting bearings; and the seismic isolation bearings are fixed to the installation seats and fixedly connected to the upper structure. The bridge supporting device, the installation method thereof and the bridge supporting system separate the conventional functions from the seismic isolation function of the bearings. The whole bridge supporting system has a simple structure, greatly decreases the bridge cost and reduces traffic pollution.

Description

technical field [0001] The invention belongs to the technical field of bridge support devices, and in particular relates to a bridge support device, an installation method and a bridge support system which separate the conventional function of a support from the auxiliary function during an earthquake. Background technique [0002] The bridge bearing is set between the superstructure of the bridge and the bridge piers, which plays the role of connecting the upper and lower, and is the key component of the bridge. Bridge bearings transfer various loads from the bridge superstructure to the piers. The general functions of the bearing include vertical load bearing function, rotation function and horizontal movement function. The normal function of the bearing can ensure the stability of the bridge under daily load. [0003] The auxiliary damping function of the support during earthquake includes: horizontal load bearing function, spring function and pull-out resistance functi...
