It is bridge seam 3 between bridge 1 and right bridge 2, its left bridge 1 side relative with right bridge 2 is installed by the first built-in fitting 4
There is the first fixture 5, the relative side of the first fixture 5 on left bridge 1 and right bridge 2 is " u "-shaped groove-like structure, so
Setting enable to polyurethane foam 6 by left bridge 1 and when pullling of right bridge 2 so that the first fixture 5 mitigate
Connection when pullling power and between polyurethane foam 6 between the both sides of polyurethane foam 6 and left bridge 1 and right bridge 2 at bonding
More stablize, the top of the inner side of bridge seam 3 is filled with polyurethane foam 6, and the first fixture 5 is wrapped in the interior of polyurethane foam 6
Portion, the top of polyurethane foam 6 is provided with resistance to compression backing plate 7 by fixing screws 8, and resistance to compression backing plate 7 spreads for load-bearing resistance to compression polyethylene
Road backing plate, its resistance to compression backing plate 7 is rectangle platy structure, and the top of resistance to compression backing plate 7 is evenly distributed with the groove of rhombus, and this sets
The contact area that can increase between bullet modeling rubber 9 and resistance to compression backing plate 7 is put, is increased and is hindered between bullet modeling rubber 9 and resistance to compression backing plate 7
Power, prevents resistance to compression backing plate 7 from the both sides of displacement resistance to compression backing plate 7 occur respectively positioned at the top of left bridge 1 and the top of right bridge 2,
Rubber 9 is moulded in the top of resistance to compression backing plate 7 filled with bullet, and the inner chamber of bullet modeling rubber 9 is respectively equipped with the first steel plate 10 and the second steel plate 11,
The part of the first steel plate 10 and the second steel plate 11 is evenly distributed with spring 12, and the first steel plate 10 and the second steel plate 11 are moulded positioned at bullet respectively
It is parallel to each other between position of the inner chamber of rubber 9 near top and the position near bottom, and the first steel plate 10 and the second steel plate 11.
The top of left bridge 1 and right bridge 2 is equipped with roadbed 17, the road on the roadbed 17 on left bridge 1 and right bridge 2
The relative side of base 17 is equipped with fill concrete 13, and fill concrete 13 is located at the both sides that bullet moulds rubber 9, fill concrete 13
The second fixture 15 is provided with by the second built-in fitting 14 near the side of bullet modeling rubber 9, the second of the left side of bullet modeling rubber 9 consolidates
Determine the bottom of the bottom of part 15 and second fixture 15 on bullet modeling rubber 9 right side by expansion bolt 16 respectively with left bridge
1 top is mutually fixed with the top of right bridge 2, and the second fixture 15 on the fill concrete 13 of bullet modeling rubber 9 both sides is all provided with
The inner chamber in bullet modeling rubber 9 both sides is put, a part of second fixture 15 in bullet modeling rubber 9 inner chamber is " u "-shaped structure, and this sets
Put the fastness that can increase and be connected between the second fixture 15 and bullet modeling rubber 9.
The first fixture 5 that the utility model passes through the setting on left bridge 1 and right bridge 2 so that poly- in bridge seam 3
Bonding strength between urethane foam 6 and left bridge 1 and right bridge 2 is further improved, and is effectively prevented polyurethane

The second fixture 15 for setting of side, the connection for enabling to bullet to mould between rubber 9 and fill concrete 13 more entered one
The reinforcing of step is, it is necessary to further illustrate：When bridge is produced because of vibrations to bullet modeling rubber 9 to be pullled, on its fill concrete 13
The second fixture 5 can effectively to bullet modeling rubber 9 both sides involve, effectively reduce bullet modeling rubber 9 with filling
Dynamics is pullled at bonding between concrete 13, the bonding that effectively prevent between elastomer rubber 9 and fill concrete 13 goes out
Now loosen, in addition, moulding the first steel plate 10 and the second steel plate 11 that are set inside rubber 9 by bullet, then coordinate the first steel plate 10
And second spring 12 set between steel plate 11 so that bullet moulds the non-deformability of rubber 9, and anti-pressure ability, and elasticity is recovered
Ability is all greatly improved.
The bridge composite seamless expansion joint, when using, because bullet modeling rubber 9 is internally provided with the first steel plate 10 and the second steel
Plate 11, significantly increases the resistance to compression that bullet moulds rubber 9, the ability of resistance to deformation, meanwhile, the first steel plate 10 and the second steel plate 11 it
Between set spring 12 so that the bridge composite seamless expansion joint be hit by a bullet modeling rubber 9 recovery capability be greatly improved, when
When vehicle passes through the bridge composite seamless expansion joint, its wheel is applied to the power on bullet modeling rubber 9, inside its bullet modeling rubber 9
The first steel plate 10 for setting, between the second steel plate 11 and the first steel plate 10 and the second steel plate 11 in the presence of spring 12, effectively
The deformation extent that bullet moulds rubber 9 is reduced, while in the presence of spring 12 so that bullet modeling rubber 9 can not only quick-recovery soon
Original state, while effective cushioning effect can also be played, in addition, when bridge is in vibrations, 2 pairs of bullets of its left bridge 1 and right bridge
When modeling rubber 9 is pullled（The dynamics pullled acts predominantly on the position mutually binded between bullet modeling rubber 9 and fill concrete 13
On）, because the side of the second fixture 15 is arranged on the inner chamber that bullet moulds rubber 9, opposite side is arranged on fill concrete 13, and by
The part being located in bullet modeling rubber 9 in the second fixture 15 is " u "-shaped structure, so that the second fixture 15 can be effective
A part of sharing to act on and pull power at bullet modeling rubber 9 and fill concrete 13 mutually bonding, it is to avoid bullet is moulded rubber 9 and is filled
Loosening occurs in bonding between concrete 13, and extension bullet moulds the service life of rubber 9, and extension bullet moulds the maintenance period of rubber 9.
In sum：The bridge composite seamless expansion joint, by the first fixation set on left bridge 1 and right bridge 2
Part 5 so that the polyurethane foam 6 and the connection between left bridge 1 and right bridge 2 filled in bridge seam 3 are more firm, while setting
The second fixture 15 put, effectively can mould the connection between rubber 9 and fill concrete 13 and further be added to bullet
Gu, coordinate the first steel plate 10 set in bullet modeling rubber 9 inner chamber, the second steel plate 11 and in the first steel plate 10 and the second steel plate 11
Between set spring 12 so that during the bridge composite seamless expansion joint use, reached long service life, resistance to deformation energy
Power is strong and effect of damping, so that effectively solving, bridge expansion joints without seals service life of the prior art is short and resistance
The weak problem of shape ability.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out various changes in the case where principle of the present utility model and spirit is not departed from, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
