Abstract
The utility model discloses an assembled corrugated steel web plate box girder, belonging to the field of a combined box girder structure. The technical problem that the corrugated steel web plate box girder is inconvenient to transport is solved. The technical scheme is adopted as follows: the assembled corrugated steel web plate box girder structurally comprises an upper wing plate, a flat bottom plate steel box body and left and right corrugated steel web plates; the assembled corrugated steel web plate box girder also comprises convex rib plates; the convex rib plates are fixed on the upper surface of the bottom plate steel box body, and are symmetrically arranged along the axial direction; convex ribs with cavities are formed by the convex rib plates; the lower ends of the left and right corrugated steel web plates are welded with the convex rib plates; and the upper ends of the left and right corrugated steel web plates are connected with the upper wing plate by virtue of connecting plates. The assembled corrugated steel web plate box girder has the beneficial effects that each spare part is fabricated by adopting a factory, the transportation efficiency of the corrugated steel web plate box girder can be effectively improved by a field installation mode, the corrugated steel web plates are connected with the bottom plate steel box body through the convex rib plates, and cracking or local carbonization of concrete when the corrugated steel web plate box girder is directly welded with the bottom plate steel box body can be prevented.
Description
Technical field
The utility model belongs to combined box beam structure field, is specifically related to a kind of pin-connected panel Wavelike steel webplate case beam of being convenient to transportation.
Background technology
The structure of Wavelike steel webplate steel case combined box beam comprises under casing, upper flange and the Wavelike steel webplate that connects under casing and upper flange, and this composite beam of steel box adopts and is prefabricated in the factory, assembled, concrete cast.Then be transported to construction ground and install, but because combined box beam assembles, take volume large, conevying efficiency is not high.Therefore need to design a kind of demountable assembled steel case combined box beam of being convenient to transportation.
Summary of the invention
The present invention is for addressing the above problem, designed a kind of pin-connected panel Wavelike steel webplate case beam, increased junction plate and convex tendon plate on the basis of original structure, Wavelike steel webplate case beam can be assembled at the scene, greatly improve conevying efficiency, but also reduced the deflection in whole assembling process.
For reaching goal of the invention, the technical solution adopted in the utility model is: a kind of pin-connected panel Wavelike steel webplate case beam, structure comprises upper flange, flat Bottom Board Steel casing and left and right Wavelike steel webplate, key is: also comprise convex tendon plate, described convex tendon plate is fixed on the upper surface of Bottom Board Steel casing and along its axial direction, is symmetrical arranged and forms the fin with cavity, and weld with described convex tendon plate the lower end of described left and right Wavelike steel webplate, upper end is connected with upper flange by junction plate.
Further, convex tendon plate is dovetail groove shape, in the cavity that described convex tendon plate and Bottom Board Steel casing form, is cast with concrete.
Further, in described Bottom Board Steel casing, location is welded with power transmission muscle and in casing, is cast with concrete.
Further, the upper end of one end of described junction plate and left and right Wavelike steel webplate is welded and fixed, and the other end is fixed by bolt or holdfast or welding and upper flange.
Further, between described junction plate and left and right Wavelike steel webplate, be provided with reinforcing rib.
The utility model beneficial effect is: each component adopt produce in factory, field erected mode can effectively improve the conevying efficiency of Wavelike steel webplate case beam, Wavelike steel webplate is connected with Bottom Board Steel casing by convex tendon plate, concrete cracking or local charing in the time of can preventing direct and Bottom Board Steel welding box body.
Below in conjunction with accompanying drawing, the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, the 1st, upper flange, the 2nd, Bottom Board Steel casing, the 3rd, left and right Wavelike steel webplate, the 4th, junction plate, the 5th, power transmission muscle, the 6th, convex tendon plate, the 7th, concrete, the 8th, reinforcing rib.
The specific embodiment
Referring to accompanying drawing, a kind of pin-connected panel Wavelike steel webplate case beam, structure comprises upper flange 1, flat Bottom Board Steel casing 2 and left and right Wavelike steel webplate 3, key is: also comprise convex tendon plate 6, described convex tendon plate 6 is fixed on the upper surface of Bottom Board Steel casing 2 and along its axial direction, is symmetrical arranged and forms the fin with cavity, and the lower end of described left and right Wavelike steel webplate 3 is connected with upper flange 1 by junction plate 4 with described convex tendon plate 6 welding, upper end.Left and right Wavelike steel webplate 3 is not directly welded and fixed with Bottom Board Steel casing 2, can prevent from making concrete seven cracking or local charing, the situation that causes whole case beam strength to reduce with 3 welding of left and right Wavelike steel webplate after Bottom Board Steel casing 2 from having poured into concrete seven.Left and right Wavelike steel webplate 3 is welded and fixed rear Pumping concrete 7 by convex tendon plate 6 and Bottom Board Steel casing 2, efficiently solves this problem.
Convex tendon plate 6 is dovetail groove shape, in the cavity that convex tendon plate 6 and Bottom Board Steel casing 2 form, is cast with concrete seven.In the cavity forming at convex tendon plate 6 and Bottom Board Steel casing 2, fill concrete 7 has further promoted the intensity of convex tendon plate 6.
The interior location of described Bottom Board Steel casing 2 is welded with power transmission muscle 5 and is cast with concrete seven.
The upper end of one end of described junction plate 4 and left and right Wavelike steel webplate 3 is welded and fixed, and the other end is fixing by bolt or holdfast or welding and upper flange 1.
3 of described junction plate 4 and left and right Wavelike steel webplates are provided with reinforcing rib 8.Inclination junction plate is set on junction plate 4, at inclination junction plate and 4 of junction plates, reinforcing rib 8 is set.The concentrated impact on its intensity of stress in the time of can avoiding reinforcing rib 8 to be directly welded and fixed with left and right Wavelike steel webplate 3.
The utility model is in the specific implementation: upper flange 1, Bottom Board Steel casing 2, left and right Wavelike steel webplate 3, junction plate 4 are good in factory process, wherein, in the manufacturing process of Bottom Board Steel casing 2, first convex tendon plate 6 are welded in Bottom Board Steel casing 2.Then each part is transported to job site assembling, Wavelike steel webplate 3 one end and 6 welding of convex tendon plate, the other end is by junction plate 4 and connector and upper flange 1 are connected and fixed accordingly.Every section of case beam has been assembled fill concrete 7 in the cavity that backward convex tendon plate 6 and Bottom Board Steel casing 2 form.
