Abstract
The utility model belongs to the technical field of bridge pier columns, and particularly relates to a double-row four-inclined-leg steel structure gate-type pier. The double-row four-inclined-leg steel structure gate-type pier comprises a number zero block and a steel cover beam. The two ends of the bottom of the steel cover beam are connected with a left-row pier column and a right-row pier column respectively. The bottom of the left-row pier column and the bottom of the right-row pier column are provided with a left bearing platform and a right bearing platform respectively. The left-row pier column comprises a first left pier column and a second left pier column. The top of the first left pier column and the top of the second left pier column intersect with each other at one end of the bottom of the steel cover beam, the bottom of the first left pier column and the bottom of the second left pier column are connected with the two ends of the left bearing platform respectively. The right-row pier column comprises a first right pier column and a second right pier column. The top of the first right pier column and the top of the second right pier column intersect with each other at the other end of the bottom of the steel cover beam, the bottom of the first right pier column and the bottom of the second right pier column are connected with the two ends of the right bearing platform respectively.

Description
Technical field
The utility model belongs to bridge pier column technical field, is specifically related to a kind of double four battered leg steel work gate-type piers.
Background technology
The bridge pier of existing continuous rigid frame and beam portion material are concrete structure, and mostly are only post bridge pier.While crossing over road interchange in city, partial continuous rigid frame bridge pier adopts concrete gate-type pier, but mostly is medium and small span continuous rigid frame.In the time that continuous rigid frame span increases, because pier load in continuous rigid frame is large, high to deformation requirements, concrete gate-type pier can not meet stressed and deformation requirements.Simultaneously, because No. 0 piece of continuous rigid frame is concrete structure, when construction, need set up falsework, take existing road under bridge, existing road is disturbed greatly, for addressing this problem, existing often according to road interchange need to adopt longspan structure cross over, be arranged in outside road by bridge pier, and the construction space of reserved No. 0 piece, but can increase like this bridge cost and difficulty of construction.
Summary of the invention
The purpose of this utility model is exactly the deficiency existing in order to solve above-mentioned background technology, the double four battered leg steel work gate-type piers that a kind of cost is low, construction speed is fast are provided, when it is applied to complicated Interchange Ramp, can reduce main span bridge span, avoid adopting the interference of long-span bridge girder construction to existing road.
The technical solution adopted in the utility model is: a kind of double four battered leg steel work gate-type piers, comprise that No. 0 piece and one end are horizontally through the steel bent cap at No. 0 piece middle part, two ends, described steel bent cap bottom are connected with respectively a left side hesitate pier stud and right row's pier stud, pier stud and the right row's pier stud bottom of hesitating, a described left side is respectively equipped with left cushion cap and right cushion cap, the described left side pier stud of hesitating comprises the first left pier stud and the second left pier stud, and described the first left pier stud is connected with left cushion cap two ends respectively in one end, steel bent cap bottom, bottom with the second left pier stud roof intersection; Described right row's pier stud comprises the first right pier stud and the second right pier stud, and described the first right pier stud is connected with right cushion cap two ends respectively in the steel bent cap bottom other end, bottom with the second right pier stud roof intersection.
Further, the spacing that hesitate between pier stud and right row's pier stud top in a described left side is less than the spacing of hesitating between pier stud and right row's pier stud bottom in a left side.
Further, between described the first left pier stud and the second left pier stud, between the first right pier stud and the second right pier stud, between the first left pier stud and the first right pier stud, the middle part between the second left pier stud and the second right pier stud is equipped with middle cross beam.
Further, on described left cushion cap and right cushion cap, be equipped with pre-embedded bolt, the described left side pier stud of hesitating is connected with left cushion cap and right cushion cap respectively by pre-embedded bolt with right row's pier stud bottom.
Double four battered leg steel work gate-type piers of the present utility model, ride over institute across on existing ring road when construction, avoided dexterously complicated Interchange Ramp; The bent cap of bridge pier and four pier studs form the stool of similar four leg, stressed clear and definite, have solved pier in existing Long Span Continuous Rigid-Frame Structure and adopt the problem of the stressed and modified difference of concrete gate-type pier; Steel work gate-type pier crossbeam adopts steel-concrete combined structure simultaneously, the double operation platform doing as No. 0 piece of beam portion of steel bent cap base plate, permanent structure and temporary structure are effectively combined, not only guarantee the rigidity of structure, and avoid the cast-in-place essential support of piece No. 0, avoid sealing ring road, in work progress, still can guarantee the unobstructed of ring road under bridge.
To complicated urban Interchange, in the time planning to build circuit and be inclined cross existing road, adopt the utility model can avoid long-span bridge girder construction, reduce investment, accelerating construction progress, reduces the interference to existing road, has wider application prospect in inter-city passenger rail.
