Background technology
For the bent cap of bridge substructure, often both sides respectively set one of block wall to prevent earthquake at the top of bent cap When girder occur laterally to fall beam destruction because of vibration, serve the traditional horizontal block design of effect of limitation beam body lateral displacement It is to improve intensity by increasing the sectional dimension and the ratio of reinforcement of block, its anti-seismic performance is improved with this.
But the effectiveness that the collision for keeping out girder during macroseism generation just with reinforced concrete block rises is limited , anti seismic efficiency can not be obviously improved with the raising of the sectional dimension and the ratio of reinforcement of block, when macroseism occurs, bridge Collapsed because girder laterally falls beam, the accident for causing whole life traffic lines to be interrupted still constantly occurs.
A large amount of engineering practices that bridge lateral block shock resistance is designed are shown, under geological process, with earthquake motion Influence, structure can occur non-directional displacement and then produce collision, and impact moment impact is huge, causes to rush horizontal block Hit, frequently result in block and hit and split, sever and crash, cause substructure to be damaged and laterally fall beam destruction, therefore in actual design It is middle that block is set to imaginable flexibility block, and the detail structure of block is optimized help to lift the anti-of bridge transverse gear block Shock stability.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of horizontal block of Urban Bridge superhigh tenacity concrete Construction, effectively to slow down Beam pounding, prevents from laterally falling beam destruction, to ensure that girder remains to normal work under severe earthquake action.
It is as follows that the utility model solves the technical scheme that its technical problem used:
The horizontal block construction of Urban Bridge superhigh tenacity concrete of the present utility model, including it is arranged at the longitudinal two ends of bent cap Horizontal block entity, it is characterized in that:The bottom of the horizontal block entity is provided with leg post along its length separately, Horizontal block entity and leg post are reinforced concrete structure, are formed by superhigh tenacity is concrete prefabricated;The corresponding portion of the bent cap Position offers corresponding with each leg post and adaptation joggle hole, and horizontal block entity is arranged on lid by leg post, the assembling of joggle hole Liang Shang.
The beneficial effects of the utility model are that block energy assembled is arranged on bent cap, can easily be installed, be changed, and are kept off Block is seamlessly connected bent cap, and the extraction-resistant behavior of block is good;Horizontal block entity and leg post are formed by superhigh tenacity is concrete prefabricated, Good toughness, deflection is larger, is caused laterally to fall beam destruction by being difficult entirely ineffective after Beam pounding, therefore can effectively improve The shock resistance of horizontal block, efficiently solves ordinary reinforced concrete by broken after Beam pounding, so as to lose antidetonation limit The problem of position effect.
Brief description of the drawings
This specification includes following three width accompanying drawing:
Fig. 1 is the front view of the horizontal block construction of the utility model Urban Bridge superhigh tenacity concrete;
