Technical field
The present invention relates to a kind of U rib production equipment, especially a kind of mould of U ribs of steel box girder production.
Background technique
In recent years, with the development of the social economy, the needs to transport development are growing, metallurgy, welding, design and frame
If construction technology is also being constantly progressive, the development that the construction of domestic and external big-span steel bridge is advanced by leaps and bounds, wherein
Orthotropic steel bridge deck refers to the bridge deck structure for being supported on and being put more energy on diaphragm plate by opening or silent ribbed stiffener, which has certainly
Many advantages, such as heavy and light, large carrying capacity, big across footpath, especially suitable in Longspan Bridge, showing good economy
And applicability, it is widely used in Large Span Bridges it is characterized in that large-scale plate sheet welding box-shaped steel structure, mainly by pushing up
The composition such as plate, bottom plate, diaphragm plate, midfeather, top plate and bottom plate, inclined bottom plate generally use U rib longitudinally to put more energy into, on the inside of steel box-girder
Along bridge to being arranged in juxtaposition, the thickness of U rib determines that length is generally identical as steel box-girder, leads to according to the top that is supported, base plate thickness
It crosses two side angle weld seams to weld together with top, bottom plate, to increase the overall stiffness of steel box-girder.
There are mainly two types of the production and processings of present country U rib: roll bending formation and bending and molding.Roll bending U rib uses roll bending material
Material is suitable for producing in enormous quantities using the online production Mold Making of continuous modification.Bending U rib, plate production in use, utilizes
The pressure of bending machine needs bending and molding twice, is suitable for small lot and produces, but due to needing bending twice, it is difficult to guarantee molding
Precision, and production efficiency is slow, and U rib stress release after molding is unable to control, and after production, leaves to form U rib stress
Release, this needs to operate master worker with enough experiences, and labor intensity is larger, and therefore, the equipment that small lot produces U rib need to be into one
Step improves.
Summary of the invention
In view of the above-mentioned problems, purpose of the present invention is to provide a kind of U ribs of steel box girder systems to solve the defect of the prior art
The mould of work can effectively solve the problems, such as that existing equipment production efficiency is low, be difficult to ensure formed precision and stress is unable to control.
To achieve the above object, the technical scheme is that, a kind of mould of U ribs of steel box girder production, including upper mold
With lower mold, the upper mold includes convex mould and attachment base, and attachment base lower central position is welded on the top of convex mould, convex
The symmetrical two sides of pattern lower end are in arc surface plush copper, and lower mold includes concave base, connecting plate and limiting device, and connecting plate is welded on
The lower part of concave base, limiting device are symmetrically welded at concave base upper surface, and the centre of concave base is in the U-type groove of perforation, on
Mold arc surface plush copper is placed in the U-shaped groove of lower mold center just above, mutually agrees with lower mold, the lower end surface of convex mould with
There is the gap of U rib thickness between the groove of concave base.
The configuration of the present invention is simple is reasonable, easy to produce, easy to operate, at low cost, by convex mould on mould and concave base into
Row production, can make U rib one-pass molding, improve production efficiency and size is accurate, shorten fabrication cycle, greatly reduce
The working strength of worker, works well, and is suitable for small lot production.
Detailed description of the invention
Fig. 1 is front view of the invention.
Fig. 2 is side view of the invention.
Fig. 3 is U rib structure figure (enlarged drawing) of the invention.
Fig. 4 is U rib side view of the invention.
Specific embodiment
It elaborates below in conjunction with attached drawing and concrete condition to a specific embodiment of the invention.
It is provided by Fig. 1-4, a kind of mould of U ribs of steel box girder production, including upper mold and lower mold, the upper mold include
Convex mould 1 and attachment base 1-1, attachment base 1-1 lower central position are welded on the top of convex mould 1, and 1 lower end of convex mould is symmetrical
Two sides are in arc surface plush copper, and lower mold includes concave base 2, connecting plate 2-1 and limiting device 2-2, and connecting plate 2-1 is welded on concave
The lower part of seat 2, limiting device 2-2 are symmetrically welded at 2 upper surface of concave base, and the centre of concave base 2 is in the U-type groove of perforation,
Upper mold arc surface plush copper is placed in the U-shaped groove of lower mold center just above, mutually agrees with lower mold, the lower end of convex mould 1
There is the gap of 3 thickness of U rib between face and the groove of concave base 2.
To guarantee better implementation effect, the attachment base 1-1 be by 3 vertically uniformly distributed the first steel plate 1-1-3 with
And first horizontally the second steel plate 1-1-1 and third steel plate 1-1-2 of steel plate 1-1-3 upper and lower ends welding constitute, it is vertical
