Space.For this reason, it may be necessary to a kind of Steel Bridge stealth bent cap structure for saving Urban Bridge down space.
Summary of the invention
The purpose of the present invention is to provide a kind of Steel Bridge stealth bent cap structure for saving Urban Bridge down space and its apply
Work method, structure is simple, promotes the height of pier stud, saves space under bridge, while construction method is easy.
Technical program of the present invention lies in：A kind of Steel Bridge stealth bent cap structure for saving Urban Bridge down space, including
The bent cap and longitudinally disposed girder being laterally arranged, the lower, transverse of the girder are provided with the space protruded into for bent cap, institute
It states bent cap to protrude into space and mutually weld with the bottom plate of girder, the lower end of bent cap is provided with pier stud, the top of bent cap and girder
Stiffener is provided between top plate.
Further, it is welded with a pair of of pier stud on the lower end surface of the bent cap, a pair of of girder, the master are provided on bent cap
Beam hole is vertically arranged on beam.
Further, the top plate of the girder is equipped with wing plate, mutually welds at the top of the wing plate and girder.
Further, the girder, bent cap and pier stud are made of Steel material respectively, the top of the bent cap and stiffener
It mutually welds, the top of the stiffener is mutually welded with the top plate of girder.
A kind of construction method of the Steel Bridge stealth bent cap structure of application saving Urban Bridge down space, including following step
Suddenly：
1）Girder lower part and beam section unwrapping wire positioning measurement corresponding with bent cap reserved one for protruding into the space of bent cap；
2）Bent cap is protruded on the bottom plate in space and being welded on girder；
3）After bent cap installs, stiffener is set between the top of bent cap and the top plate of girder, makes the top of bent cap and adds
The bottom of strong reinforcing bar is mutually welded, and the top plate of girder is mutually welded with the top of stiffener；
4）After stiffener is welded and fixed, start the lifting of girder, girder is lifted on the position of pier stud together with bent cap, welds
Splicing is completed at the bottom plate of bent cap and the top of pier stud.
Compared with prior art, the present invention has the following advantages that：Pass through the reserved bent cap of surveying setting-out on girder
Bent cap is mounted in the inner space of girder by space, by the Combination Welding of girder and bent cap, by the top of pier stud and bent cap and
Girder is grouped together, and bent cap is hidden into girder completely or partially, bent cap structure not visible from outside or can only see part lid
Girder construction promotes the height of pier stud, keeps bridge more beautiful, saves space under bridge.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is side view of the invention；
Fig. 3 is top view of the invention；
In figure：1- girder, 2- bent cap, 3- pier stud, 4- beam hole, 5- wing plate, 6- stiffener.
Specific embodiment
To make the foregoing features and advantages of the present invention clearer and more comprehensible, special embodiment below, and cooperate attached drawing, make detailed
It is carefully described as follows, but the present invention is not limited thereto.
Referring to figs. 1 to Fig. 3
A kind of Steel Bridge stealth bent cap structure for saving Urban Bridge down space, including the bent cap 2 that is laterally arranged and longitudinally disposed
Girder 1, the lower, transverse of the girder is provided with the reserved space protruded into for bent cap of measurement and positioning unwrapping wire, the bent cap
Protrude into space and mutually welded with the bottom plate of girder, the lower end of bent cap is provided with pier stud 3, the top plate of the top of bent cap and girder it
Between be provided with stiffener 6.So that bent cap is hidden into girder completely or partially, bridge is made to can't see the presence or only of bent cap
It can see part bent cap structure, bent cap and stiffener are hidden into together in girder space, are promoted the height of pier stud, are made bridge more
Beauty saves space under bridge.And girder and load thereon can be directly passed in pier stud, sheared and born at bent cap position
The effect of moment of flexure, the top that stiffener 6 is located at girder can bear the effect of pulling force, can also bear the effect of shearing.
In the present embodiment, it is welded with a pair of of pier stud on the lower end surface of the bent cap, a pair of of girder is provided on bent cap, it is described
Beam hole is vertically arranged on girder.
In the present embodiment, the top plate of the girder is equipped with both sides respectively to along the wing plate 5 extended, the wing plate and master
Back portion is mutually welded.
In the present embodiment, the girder, bent cap and pier stud are made of Steel material respectively, the top of the bent cap and reinforcement steel
Muscle mutually welds, and the top of the stiffener is mutually welded with the top plate of girder, improves bonding strength.
A kind of construction method of the Steel Bridge stealth bent cap structure of application saving Urban Bridge down space, including following step
