Description

Technical Field

[0001] The utility model belongs to the technical field of bridge supports, and in particular relates to a support stabilizing device and a bridge support. Background Art

[0002] The bridge bearing is an important structural component connecting the upper and lower structures of the bridge, and is located between the bridge and the pad stone. The bridge bearing can transfer the load and deformation (displacement and rotation) borne by the upper structure of the bridge to the lower structure of the bridge, and is an important force transmission device of the bridge. The existing seismic isolation rubber bearing has uniform shear stiffness in all directions. During the installation of the seismic isolation rubber bearing, the shear deformation of the bearing will be caused by the swing of the beam body when the beam falls. Due to the viscoelasticity of the bearing rubber material itself, the self-resetting ability of the bearing is weak, which can easily lead to difficulty in returning the bearing to the correct position, and the anchor hole is out of position, increasing the difficulty of construction. In addition, during the normal use of the bearing, the beam body is prone to lateral displacement due to the side wind of the bridge. Utility Model Content

DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Please also read Figures 1 to 6, a support stabilization device provided by the utility model is now described. The support stabilization device is arranged between the top plate 11 and the bottom plate 12 of the seismic isolation rubber support 1, and the support 1 stabilization device includes an upper fixing frame 2, a lower fixing frame 3 and a support stabilization module 4; the upper fixing frame 2 includes a first connecting portion 21 and a first adjusting portion 22; the first connecting portion 21 is connected to the top plate 11 of the seismic isolation rubber support 1; the lower fixing frame 3 includes a second connecting portion 31 and a second adjusting portion 32; the second connecting portion 31 is connected to the bottom plate 12 of the seismic isolation rubber support 1; the top and bottom of the support stabilization module 4 are respectively provided with an upper adjustment space 411 and a lower adjustment space 412; the first adjusting portion 22 is located in the upper adjustment space 411, and the width of the first adjusting portion 22 is smaller than the width of the upper adjustment space 411; the second adjusting portion 32 is located in the lower adjustment space 412, and the width of the second adjusting portion 32 is smaller than the width of the lower adjustment space 412.

[0033] The utility model provides a support 1 stabilization device. Compared with the prior art, when installing the seismic isolation rubber support 1, the positioning block 51 can constrain the displacement of the support 1 along the bridge direction; by setting the upper adjustment space 411, the lower adjustment space 412, the first adjustment part 22 and the second adjustment part 32, the lateral stability of the support 1 can be ensured, and the lateral displacement of the support 1 can be controlled within a preset range; after the first adjustment part 22 contacts the side of the support stabilization module 4, the support stabilization module 4 will provide a reaction force to the first adjustment part 22, thereby facilitating the self-reset of the support 1 and returning the support 1 to the correct position. Through the above-mentioned settings of the present application, the support 1 can be assisted to return to the correct position, the situation of anchor hole misalignment can be reduced, and the construction difficulty can be reduced.

[0034] It should be noted that when an earthquake occurs, if the shear force of the support 1 is greater than a preset value, the connection between the first adjustment portion 22 and the first connection portion 21 breaks, or the connection between the second adjustment portion 32 and the second connection portion 31 breaks, which can make the seismic isolation rubber support 1 in a free state to achieve the effect of seismic isolation. During normal use, since the support stabilization module 4 can provide a reaction force to the first adjustment portion 22 and the second adjustment portion 32, it can help the support 1 to reset itself and reduce the situation where the seismic isolation rubber support 1 has a large displacement.

[0035] In some embodiments, Figures 1 to 6As shown, the support stabilization module 4 includes two parallel side panels 41 and a support portion 42 connected between the two side panels 41; the top of the support portion 42 is an upper adjustment space 411, and the bottom of the support portion 42 is a lower adjustment space 412; the top of the second adjustment portion 32 is in contact with the bottom of the support portion 42, and a gap is formed between the bottom of the first adjustment portion 22 and the top of the support portion 42. The top of the second adjustment portion 32 is connected to an elastic plate 33, which is an arc-shaped structure, and the convex surface of the elastic plate 33 is in contact with the support portion 42. The support portion 42 and the side panels 41 can be fixed by bolts or rivets. The side panels 41 are spring steel plates, and the upper fixing frame 2 and the lower fixing frame 3 are both arranged side by side.

[0036] It should be noted that when the support 1 turns a corner, the top plate 11 and the bottom plate 12 of the support 1 will be relatively tilted; by providing an elastic plate 33 on the second adjustment portion 32 and forming a gap between the first adjustment portion 22 and the support portion 42, the support stabilization module 4 can adapt to the turning angle of the support 1.

[0037] In some embodiments, Figures 1 to 6 As shown, the number of lower fixing frames 3 is greater than one, and the number of lower fixing frames 3 is an odd number; the second adjustment portion 32 on the lower fixing frame 3 at the middle position is connected with an arc-shaped protrusion 34, and the arc-shaped protrusion 34 contacts the support portion 42; the second adjustment portions 32 on the remaining lower fixing frames 3 are connected with an elastic plate 33, and the elastic plate 33 is an arc-shaped structure, and the convex surface of the elastic plate 33 contacts the support portion 42.

[0038] It should be noted that, by providing the arc-shaped protrusion 34 on the second adjustment portion 32 at the middle position, after the support 1 turns a corner, a relative inclination occurs between the top plate 11 and the bottom plate 12 of the support 1, at which time one end of the support portion 42 is pressed downward and the other end is tilted upward, that is, the support portion 42 can rotate around the arc-shaped protrusion 34 at the middle position. Through the above-mentioned configuration of the present application, the support stabilization module 4 can adapt to the turning angle of the support 1.

[0039] In some embodiments, Figures 1 to 6As shown, the support 1 stabilization device also includes a pre-positioning structure 5 arranged in the upper adjustment space 411 and the lower adjustment space 412, and the pre-positioning structure 5 includes four positioning blocks 51 respectively arranged at the four corners of the support stabilization module 4, and each positioning block 51 is connected to the support stabilization module 4 by bolts; wherein, the positioning block 51 located in the upper adjustment space 411 contacts the side of the first adjustment part 22, and the positioning block 51 located in the lower adjustment space 412 contacts the side of the second adjustment part 32; after the support 1 stabilization device is installed, the bolts 52 of the upper adjustment space 411 and all the positioning blocks 51 are separated from the side plate 41, and the bolts 52 of the lower adjustment space 412 are retained; through the above-mentioned arrangement, during normal use, the bolts 52 in the lower adjustment space 412 can limit the second adjustment part 32 in the direction along the bridge.

[0040] It should be noted that, during the installation of the support 1, the positioning block 51 can position the first adjustment portion 22 and the second adjustment portion 32 to restrict the displacement of the support 1 along the bridge direction. After the support 1 is installed, the four positioning blocks 51 and the four bolts 52 are all removed, and then the two bolts 52 in the lower adjustment space 412 are installed to the original position.

[0041] Specifically, a mounting hole is provided on the side plate 41 at a position corresponding to the positioning block 51 , and after the threaded end of the bolt 52 passes through the through holes on the two side plates 41 , the positioning block 51 is fixed between the two side plates 41 through the cooperation of the nut and the bolt 52 .

[0042] In some embodiments, Figures 1 to 6 As shown, a force limiting groove 23 is provided at the connection between the first connecting portion 21 and the first adjusting portion 22; a force limiting groove 23 is provided at the connection between the second connecting portion 31 and the second adjusting portion 32; the length of the first adjusting portion 22 is smaller than the length of the first connecting portion 21, and the length of the second adjusting portion 32 is smaller than the length of the second connecting portion 31.

[0043] It should be noted that, in this embodiment, the above fixing frame 2 is used as an example for explanation; by setting a force limiting groove 23 at the connection between the first connecting part 21 and the first adjusting part 22, and the length of the first adjusting part 22 is less than the length of the first connecting part 21, therefore, after the first adjusting part 22 contacts the side plate 41 and the shear force of the first adjusting part 22 is greater than the preset value, the first adjusting part 22 and the first connecting part 21 will break at the position of the force limiting groove 23, so that the seismic isolation rubber bearing 1 is in a free state, and the seismic isolation effect can be achieved.

[0044] In addition, the upper fixing frame 2 and the lower fixing frame 3 have the same structure. This embodiment is described by taking the upper fixing frame 2 as an example. The first connecting portion 21 can be a plate-like structure or other shapes. The first connecting portion 21 is fixed to the top plate 11 of the seismic isolation rubber bearing 1 by bolts. The first adjusting portion 22 can be fixedly connected to the first connecting portion 21 or detachably connected. The first adjusting portion 22 can be a plate-like structure or a columnar structure.

[0045] When the first adjustment part 22 is a columnar structure, the force limiting groove 23 is a conical groove, that is, one end of the first adjustment part 22 is a conical surface, and the small end of the conical surface of the first adjustment part 22 is connected to the first connecting part 21; a conical force limiting groove 23 is formed between the conical surface of the first adjustment part 22 and the first connecting part 21.

[0046] Based on the same inventive concept, the present application also provides a bridge bearing, including a bearing 1 body and two sets of bearing 1 stabilizing devices, wherein the two sets of bearing 1 stabilizing devices are respectively arranged on opposite sides of the bearing 1 body.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
