As long as all by the protection of Patent Law in the scope of the claims of the utility model.
As shown in Figure 1 to Figure 3, a kind of expanded joint structure applied to bridge, including left matrix 1, right matrix 2, bloom 3,
Cover board 4 and connector 5, the right side of the left matrix 1 and the left side of right matrix 2 are oppositely arranged to form expansion joint, the steel
Block 3 is placed in the expansion joint, and the cover board 4 is covered on the expansion joint, and the connector 5 includes big sleeve 51, small set
Cylinder 52 and spring 53, the small sleeve 52 are inserted into the big sleeve 51, the outer diameter of the small sleeve 52 and the big sleeve 51
Internal diameter it is equal, the spring 53 is inserted into the small sleeve 52, and one end of the spring 53 is resisted against the small sleeve 52
Bottom, the other end are resisted against the bottom of the big sleeve 51, between the cover board 4 and the left matrix 1, the cover board 4 and institute
It states between right matrix 2, between the cover board 4 and the bloom 3, between the left matrix 1 and the bloom 3 and the bloom
It is connected by the connector 5 between 3 and the right matrix 2, but the dimensions of connector 5 that they are used is different
Sample, the big sleeve 51 of the connector 5 and the root of small sleeve 52 are individually fixed in the connecting component of its connection, specifically
It can be by the way of welding.
Under this structure setting state, the cover board 4 forms expansion joint and protects, described in the pressure that undertakes pass through connection
Part 5 is mainly transferred to the bloom 3, the left matrix 1 and right matrix 2 and is connect by connector 5 with bloom 3, in the horizontal direction
On certain fixed effect is generated to bloom 3 so that the bloom 3 is difficult to move in the horizontal direction.
The big sleeve 51 and small sleeve 52 are cylindric, the big sleeve 51 and the small sleeve 52 that one end has opening
Spring 53 can be formed and be protected, while also can avoid spring to a certain extent in radially fixed spring 53 of spring 53
53 run-off the straights and the transmission effect of influence power, can coat appropriate between the big sleeve 51 and the contact surface of small sleeve 52
Lubricating oil.
Further, the end of the big sleeve 51 and the end of small sleeve 52 are pasted equipped with shock ring 54, the damping
Ring 54 uses rubber material.When the impact force being subject to is larger, the big sleeve 51 and 52 relative motion of small sleeve, the big set
The end of cylinder 51 may collide with the surface of connecting component, and the end of the small sleeve 52 may be with the bottom of big sleeve 51
It collides, the shock ring 54 is set, the damage collided to big sleeve 51 and small sleeve 52 can be effectively reduced, can also be had
Effect reduces the noise generated when collision.
Further, the upper surface of the left matrix 1 is equipped with the first sealing ditch 11, and the longitudinal section of the first sealing ditch 11 is taken turns

Left bending degree is gradually increased, and the length direction of the second sealing ditch 21 is parallel with the width direction of the right matrix 2.Herein
Under structure setting, hindered first by the first sealing ditch 11 and the second sealing ditch 21 to expansion joint direction flowing water
Gear flows into the first sealing ditch 11 and the second sealing ditch 21, and when the traveling due to vehicle generates vibration, water is easier from curved
Qu Chengdu flows out in lesser direction the first sealing ditch 11 and the second sealing ditch 21, i.e., flows to the direction far from the expansion joint
The first sealing ditch 11 and the second sealing ditch 21 out, it follows that the first sealing ditch 11 and the second sealing ditch 21 can
It realizes to the good protecting effect in the expansion joint, water can be effectively reduced and enter expansion joint, cause the corrosion of expansion joint component.
Further, the right end edge of the first sealing ditch 11 is equipped with the first damping block 12, the second sealing ditch 21
Left end edge be equipped with the second damping block 22.The effect of first damping block 12 and the second damping block 22 is first is that be and institute
The first sealing ditch 11 and the cooperation of the second sealing ditch 21 are stated, further water is stopped to enter in expansion joint, expansion joint is formed and is protected；Two
Be when the cover board 4 bears biggish strength be deformed with left matrix 1 or right matrix 2 collision when, first damping
Block 12 and the second damping block 22, which can be formed the cover board 4, to be stopped, and left matrix 1 or the right side described in 4 direct collision of cover board are avoided
Matrix 2, and reduce the generation of noise.
Further, first damping block 12 and the second damping block 22 are all made of rubber material.
It further, further include left plate 6, right steel plate 7, the first pre embedded bolt 81, the first nut 82, the second pre embedded bolt 91
With the second nut 92, first pre embedded bolt 81 is inserted into the left matrix 1 by the right side of the left matrix 1, and described the
One pre embedded bolt 81 passes through the left plate 6, and first nut 82 cooperates with first pre embedded bolt 81 by the left steel
Plate 6 is fixed on the right side of the left matrix 1, and second pre embedded bolt 91 is inserted into the right matrix 2, and described second is pre-
Screw rod 91 is buried across the right steel plate 7, second nut 92 cooperates with second pre embedded bolt 91 consolidates the right steel plate 7
Due on the left side of the right matrix 2.The left plate 6 and right steel plate 7 can reinforce the structural strength at expansion joint, and promotion is stretched
Contract the ability to ward off risks stitched.
The above-mentioned description to embodiment is to understand convenient for those skilled in the art and using originally practical new
Type, person skilled in the art obviously easily can make various modifications to embodiment, and described herein general
Principle is applied in other embodiments without having to go through creative labor.Therefore, the utility model is not limited to the above embodiments,
