Abstract
The utility model discloses a kind of cable-stayed type bridge earthquake resistance components, and including girder and bridge pier, wherein being equipped with brace in the both sides of the bridge pier, the both ends of the brace are hinged by bottom of the connects bearing respectively with the side of the bridge pier and girder；Connecting hole is equipped in the connects bearing, perforation is equipped at the both ends of the brace, the connecting hole connect rod iron connection with being punched through；The connects bearing includes connecting seat and joint face, the joint face is vertically set on the connecting seat, the connecting hole is located on the joint face, when there is earthquake, pass through the effect of brace, power horizontal seismic force being converted on vertical direction is offset using the gravity of bridge floor in itself, ensures that safety of the bridge in earthquake.
Description
Technical field
The utility model is related to a kind of bridge earthquake resistance component, especially a kind of cable-stayed type bridge earthquake resistance component.
Background technology
At present, bridge earthquake resistance system majority still uses anti-seismic stop structure, i.e., under geological process, the plastic deformation of bridge,
Energy consumption position is predominantly located at bridge pier, for such system, bridge pier at the corresponding hold-down support of beam structure by seismic force compared with
Greatly, it is generally the case that when pier stud is higher, under E2 seismic force effects, the horizontal anti-seismic ability of hold-down support longitudinal direction block is not
It meets the requirements, the corresponding bridge pier horizontal displacement in hold-down support place, seismic force are also larger, and seismic resistance calculation is difficult to meet the requirements.
Utility model content
The technical assignment of the utility model is to be directed to more than the deficiencies in the prior art, and provides a kind of cable-stayed type bridge earthquake resistance
Component.
Technical solution is used by the utility model solves its technical problem：A kind of cable-stayed type bridge earthquake resistance component, packet
Girder and bridge pier are included, wherein being equipped with brace in the both sides of the bridge pier, the both ends of the brace pass through connects bearing point
Bottom not with the side of the bridge pier and girder is hinged.
It is further improved：Connecting hole is equipped in the connects bearing, perforation is equipped at the both ends of the brace, it is described
Connecting hole connect rod iron connection with being punched through.
It is further improved：The connects bearing includes connecting seat and joint face, and the joint face is vertically set on the company
On joint chair, the connecting hole is located on the joint face.
It is further improved：The connecting hole is bar hole, in the connection rod iron peripheral hardware rubber sleeve.
The advantages of the utility model：When there is earthquake, by the effect of brace, horizontal seismic force is converted into vertical side
Upward power is offset using the gravity of bridge floor in itself, ensures that safety of the bridge in earthquake.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 be the utility model bridge floor by earthquake effect when force analysis figure.
Fig. 3 is the structure diagram of the utility model connects bearing.
Fig. 4 is the connection diagram of the utility model brace connects bearing.
Specific embodiment
The utility model is described below with reference to the accompanying drawings of the specification.
As shown in the figure, a kind of cable-stayed type antidetonation bridge, including bridge floor 1 and bridge pier 2, wherein equal in the both sides of the bridge pier 2
Equipped with brace 4, the both ends of the brace 4 by connects bearing 3, respectively with the side of the bridge pier 2 and the bottom of bridge floor 1
It is hinged；Connecting hole 30 is equipped in the connects bearing 3, perforation 40, the connecting hole 30 are equipped at the both ends of the brace 4
It is connect with perforation 400 by pitman 5；The connects bearing packet 3 includes connecting seat 32 and joint face 31, and the joint face 31 is vertical
It is arranged on the connecting seat 32, the connecting hole 30 is located on the joint face 31；The connecting hole 30 is bar hole, in institute
State 5 peripheral hardware rubber sleeve of pitman.
Its operation principle is：Such as Fig. 2, when earthquake causes 1 horizontal direction of bridge floor to move, if bridge floor 1 is to move right,
The brace 4 for being now placed in 1 right side of bridge floor will be by a power to the right, and is located at the brace 4 in 1 left side of bridge floor, because
Its bottom is hinged with the connects bearing in left side 3, be located in this way left side brace 4 will using the bottom of brace 4 as the center of circle,
Start to turn right, if the brace 4 in left side is to turning right, then the top of left side brace 4 be just necessarily required to
Upper movement, at this time due to the top for thering is bridge floor 1 to be pressed in brace 4 so that the brace 4 in left side can not move up rotation, from
And realize the stabilization to bridge floor 1, if the moving direction of bridge floor 1 is to the left, principle with to the right when be the same.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly used in
Other related technical areas are equally included in the patent within the scope of the utility model.
