Description
Technical field
This utility model relates to bridge structure technical field, particularly relates to a kind of bridge twin shaft pier bracing means.
Background technology
In existing overhead bridge structure, bracket structure is due to can so that elevated bridge saves bent cap at transition pier place, and the omission of bent cap simplifies structure, has saved raw material, reduces cost, thus is constantly subjected to the favor of Bridge Design teacher.
But, along with China's expanding economy, vehicle flowrate and vehicle load on elevated bridge increase day by day, and the shortcoming of bracket structure also comes out gradually.Such as, when the bracket structure that elevated bridge uses upper and lower bracket to connect, due to the setting of horizontal block, working place only only small around the bearing between bracket, bring great inconvenience to the replacing of bearing.Meanwhile, the restriction of working place is easily caused by the dead angle of routine servicing, and the safe operation for bridge brings certain hidden danger.Additionally, due to the increase of vehicle flowrate on elevated bridge, the durability of bracket structure reduces.
Therefore, those skilled in the art need research a kind of simple in construction, convenient for installation and maintenance, safe and reliable bridge structure badly.
Utility model content
Because the drawbacks described above of prior art, the utility model proposes a kind of simple in construction, convenient for installation and maintenance, safe and reliable bridge twin shaft pier bracing means.
For achieving the above object, this utility model provides a kind of bridge twin shaft pier bracing means, including steel corbel bent cap, being provided with two anchor ears in described steel corbel bent cap, described steel corbel bent cap is arranged in twin shaft pier and is fixedly connected on described twin shaft pier by being arranged in the securing member of described anchor ear；The top of described steel corbel bent cap is provided with bearing, is additionally provided with bearing cushion block between described bearing and described steel corbel bent cap；The top of described steel corbel bent cap is additionally provided with for limiting the limited block that bridge superstructure moves.
In some preferred implementations, described securing member is crab-bolt.
In some preferred implementations, between described bearing and described bridge superstructure, it is provided with steel plate.
In some preferred implementations, between the contact surface of described bridge superstructure and described limited block, it is provided with rubber blanket.
The beneficial effects of the utility model:
Said structure of the present utility model designs, owing to bearing to be arranged at the both sides of stub, and the arranged outside at stub has steel bracket structure, change the overlaying relation of existing highway bridge superstructure and bearing, it is arranged on the same level line of stub both sides by bearing, thus changing the stress of bridge superstructure, decreasing the stress of bridge superstructure, reducing the probability that bridge superstructure occurs to destroy.Additionally, the change of support position relation, expand spacing horizontal between bearing, add the ability of bridge structure antidumping, improve the safety of bridge application.
It addition, be provided with steel plate between bearing and bridge superstructure, the setting of steel plate, simplify the difficulty that height of support adjusts.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to be fully understood from the purpose of this utility model, feature and effect.

Detailed description of the invention
As shown in Figures 1 to 7, the present embodiment proposes a kind of bridge twin shaft pier bracing means, including two stubs 1 (i.e. twin shaft pier), steel corbel bent cap 2, bearing 3 and bearing cushion block 4.
As shown in Figure 4, two anchor ears 21 it are fixedly installed in steel corbel bent cap 2.As it is shown in fig. 7, anchor ear 21 is made up of the steel construction 211 that two halves are circular, the steel construction 211 of two halves circle is fixed as one by two securing members.
In other embodiments, the cross section of anchor ear 21 can adopt different version, such as rectangle etc. according to the shape of stub.
As shown in Figure 3 and Figure 5, steel corbel bent cap 2 is arranged in two stubs 1, and is fixedly connected on two stubs 1 by being arranged in the multiple crab-bolts 22 being used as securing member of anchor ear 21.
As depicted in figs. 1 and 2, the top of the steel corbel bent cap 2 of each stub 1 both sides is respectively arranged with a bearing 3, is additionally provided with bearing cushion block 4 between bearing 3 and steel corbel bent cap 2.According to the differing heights between bridge superstructure A and stub 1, it is possible to adopt the cushion block of differing heights, simplify the installation difficulty of bearing.
By above-mentioned structural design, bearing is moved on to from the top of stub the both sides of stub, change the overlaying relation of existing highway bridge superstructure A and bearing, it is arranged on the same level line of stub both sides by bearing, thus changing the stress of bridge superstructure, decrease the stress of bridge superstructure, reduce the probability that bridge superstructure occurs to destroy.Additionally, the change of support position relation, expand spacing horizontal between bearing, add the ability of bridge structure antidumping, improve the safety of bridge application.
As shown in Figure 6, in order to the movement of bridge superstructure is reasonably limited, the upper end of steel corbel bent cap 2 is additionally provided with for limiting the limited block 6 that bridge superstructure moves.
As in figure 2 it is shown, for the mobile space increasing bridge superstructure A, reduce the friction between bridge superstructure A and limited block 6, be provided with rubber blanket 7 between the contact surface of bridge superstructure A and limited block 6.The effect of rubber blanket is the effect of impact between buffering bridge superstructure and limited block.
In order to simplify the adjustment difficulty of height of support further, between bearing 3 and bridge superstructure A, it is provided with steel plate 8.
Preferred embodiment of the present utility model described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in the protection domain being defined in the patent claims.
