Description
Technical field
The invention belongs to bridge expanssion joint technical fields, more particularly to a kind of modular multidirectional displacement comb plate, comb joint rubber slab
Bridge extension joint.
Background technique
Currently, the modular multi-directional deflection comb plate, comb joint bridge extension joint having been known is by Support bracket, rotation control
The compositions such as seat, shaft, movable fishback, water guide structure, fixed broach plate, T-bolt group and steel fiber reinforced concrete.When flexible dress
When setting load, movable fishback is occured bending and deformation by downward power, and movable fishback is rotated around main bridge side shaft, and load is unloaded
When going, movable fishback restores again because of the elasticity of its own.
In the transmitting of the power of whole device, entirely rigid transition, such as movable fishback in the junction of structural member and master
Metal friction will certainly be generated between bridge, rotation control seat and Support bracket, huge noise is generated, causes the rust of steel part
It loses, the rigid collision between steel part causes the fatigue damage of connecting portion, this outer shaft attachment has steel part bearing, and uses spiral shell
Bolt-lock is dead, can not achieve three-dimensional movement or three-dimensional moving range is minimum, can not adapt to the kinetic characteristic of bridge.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of reduction noise, it is able to achieve three-dimensional motion, with long service life
Modular multidirectional displacement comb plate, comb joint rubber slab bridge extension joint.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of modular multidirectional displacement comb plate, comb joint rubber slab bridge extension joint, including fixed broach plate, movable fishback,

Offset plate, lower basin seat are mounted on support supporting plate pre-buried on steel box-girder, and rubber slab is mounted between upper and lower basin seat, movable comb teeth
Plate is located in upper basin seat, and movable fishback is connect by multiple connection bolts with support supporting plate, connects the lower end installation pressure of bolt
Contracting spring simultaneously passes through nut check.
The multidirectional displacement comb plate, comb joint rubber slab bridge extension joint of invention unit formula, further, the steel box-girder and mixed
Rubber fastening band is installed between solidifying soil beam.
The multidirectional displacement comb plate, comb joint rubber slab bridge extension joint of invention unit formula, further, the rubber slab it is interior
Plurality of steel plates is arranged in portion interval.
The multidirectional displacement comb plate, comb joint rubber slab bridge extension joint of invention unit formula, further, the beams of concrete and
The multiple embedded ribs of setting in concrete layer, fixed broach plate are fixedly connected by installation bolt with embedded ribs.
The multidirectional displacement comb plate, comb joint rubber slab bridge extension joint of invention unit formula, further, the fixed broach plate
Stainless steel plate is set between concrete layer.
The multidirectional displacement comb plate, comb joint rubber slab bridge extension joint of invention unit formula, it is pre-buried in movable fishback and steel girder box
Support supporting plate between be mounted with rubber slab, by rubber slab transmit wheel act on the wheel load on movable fishback.When
When bridge floor has vehicle to pass through, telescopic device carries certain load, passes to rubber slab, rubber by movable fishback, upper basin seat
Plate is squeezed deformation, and rubber slab is flexible product, and damping action can be generated in the transmittance process of power, absorbs power, to vehicle
Buffer function is played to the impact force of bridge floor, avoids directly contacting between metal and metal, avoid generating between component
Corrosion, protects movable fishback and its lower support member, reduces noise, it is often more important that has fishback telescopic device
There is multidirectional displacement function, that is, adapts to the multidirectional displacement of bridge and displacement and the corner of all directions of generation, extend telescopic device
Service life, improve road-ability.
Modular multidirectional displacement comb plate, comb joint rubber slab bridge extension joint of the invention is made with reference to the accompanying drawing further
Explanation.
Detailed description of the invention
Fig. 1 is the main view of the multidirectional displacement comb plate, comb joint rubber slab bridge extension joint of invention unit formula；
Fig. 2 is the top view of the multidirectional displacement comb plate, comb joint rubber slab bridge extension joint of invention unit formula；
Fig. 3 is the cross-sectional view of rubber slab.
Specific embodiment
As shown in Figure 1 and Figure 2, the multidirectional displacement comb plate, comb joint rubber slab bridge extension joint of invention unit formula includes fixed comb
Concrete layer 7, beams of concrete 6 is arranged on beams of concrete 6 in tooth plate 1, movable fishback 2, upper basin seat 3, lower basin seat 4, rubber slab 5
With multiple embedded ribs 8 are set in concrete layer 7, between fixed broach plate 1 and concrete layer 7 be arranged stainless steel plate 9, fixed broach
Plate 1 is fixedly connected by installing bolt 10 with embedded ribs 8.
Lower basin seat 4 is mounted on support supporting plate 13 pre-buried on steel box-girder 11, rubber slab 5 be mounted on upper and lower basin seat 3,4 it
Between.As shown in connection with fig. 3, plurality of steel plates 51 is arranged in the inside interval of rubber slab 5.Movable fishback 2 is located in upper basin seat 3, activity
Fishback 2 is connect by multiple connection bolts 21 with support supporting plate 13, and the lower end installation compressed spring 22 of connection bolt 21 is simultaneously led to
