Description
Technical field
The utility model is related to one kind being used for civil engineering bridge technology field, be more particularly to a kind of butterfly shape steel web
The mixed combination main beam structure of steel-.
Background technology
Beam bridge is so that by the girder based on curved, as the bridge of supporting member, middle girder refers in bridge superstructure
In, it supports various loads and is passed to the beam of pier, platform.Different by material character by girder, bridge structure generally can be divided into
Wooden bridge, masonry bridge, reinforced concrete girder, steel bridge, steel-concrete combined structure bridge etc..
Steel-concrete combined structure beam bridge be by steel and two kinds of concrete girder material of different nature, it is combined made of one
Kind beam bridge structure form.Since it takes full advantage of steel tensile strength and the high material property of concrete crushing strength, the two
Between combined by shear connector it is integral, avoid beam bridge concrete in tension cracking the problem of, have reasonable stress, shape
Advantage beautiful, easy for construction.
Traditional steel-concrete composite beam bridge girder structure generally has T-type combination beam, concrete slab steel box-girder, waveform
Steel web box girder, steel truss combination beam etc..T-type combination beam, composite beam of steel box dead weight are larger, and due to for real fu jie structure, wind resistance
It can force difference；Although steel truss combination beam greatly reduces compared with solid web girder weight, since web is steel truss, bearing capacity is relatively
It is small.Thus on the whole, the main deficiency of traditional steel concrete composite structure beam bridge is：（1）Conduct oneself with dignity larger（2）Wind loading rating is poor
（3）Bearing capacity is smaller（4）Good appearance degree needs to be further increased.
So in this background, develop a kind of dead weight compared with light, wind loading rating is good, reasonable stress and good appearance it is new
The mixed combination main beam structure of butterfly shape steel web steel-, has great practical value.
Utility model content
The purpose of this utility model is to be to provide a kind of mixed combination main beam structure of butterfly shape steel web steel-, overcomes traditional steel
The mixed main beam structure that combines is from the problem that great, wind loading rating is small, bearing capacity is low.
To achieve the goals above, the utility model uses following technical measures：
A kind of butterfly shape steel web steel reinforced concrete combines main beam structure, including concrete roof, concrete floor, butterfly steel web,
Be located by connecting reinforcing bar, top plate prestress wire, baseboard prestress steel strand wires, and the butterfly shape steel web includes two row, two row
Butterfly steel web is mutually parallel, and each column butterfly steel web is arranged along the longitudinal direction of concrete roof and concrete floor；,
It is equipped with web hole at the top and bottom of the butterfly shape steel web, butterfly shape steel web passes through the steel that is located by connecting across web hole
Muscle is connected with concrete top, bottom plate to form that steel-is mixed to combine main girder frame.
Further, the concrete roof, concrete floor prestress pipe in be embedded with prestress steel twist
Line, after pipeline pneumatic mortar, after so that prestress wire and top, underplate concrete is combined into entirety, with top, underplate concrete,
The common bearing load of butterfly shape steel web.
Further, the butterfly shape steel web is 2-3cm thickness plain plates, and cross section is butterfly.
Further, each column butterfly shape steel web includes multiple butterfly-type steel plates, and multiple butterfly shape steel webs are sequentially arranged.
Further, the prestress wire includes more, along the longitudinal direction of concrete roof and concrete floor
Direction is arranged.
Further, the bottom of the concrete roof is set there are two downwardly convex radian；The concrete floor
Top also be provided with two radians to raise up, the two row butterfly shape steel webs are arranged on the radian in two protrusions.
The utility model has the following advantages compared with the existing technology：
（1）Butterfly shape steel web can also be both pressurized with tension, and main beam structure stress is more reasonable, with conventional upper
Steel-mixes frame combination beam and compares, and improves beam body bearing capacity；
（2）Web uses butterfly-type steel plate, solves real abdomen steel plate concrete composite beam bridge and is highly prone to Wind effects
Deficiency, and material utilization amount is less, has good engineering economy；
（3）It is more beautiful that butterfly shape steel web steel-mixes main beam structure appearance.
