Abstract
The invention relates to a method for welding bridge cornice decorative sheets, in particular to a reversible deformation welding method for city highway bridge cornice decorative sheet light steel plates. The method for welding the bridge cornice decorative sheets is characterized by including the following steps that first, a steel plate material A is cut into the required decorative sheet B and C according to the specific needs; second, the peripheries of the decorative sheet B and C are knocked with a hammer to release the internal stress of the decorative sheet B and C so that the decorative sheet B and C can be levelled; third, the levelled decorative sheet B and C are spliced and welded by using a low-voltage current, welded joints at the welding positions are knocked with the hammer to release the internal stress so that the sheets can be levelled, the voltage of the low-voltage current is 23-25V and the current of the low-voltage current is 180-200A; and fourth, plug welding holes are formed in the positions, connected with a steel angle and cornice flange, of the decorative sheet B and C, and accordingly the decorative sheet B and C can be fixedly welded with the steel angle and cornice transverse partition flange through the plug welding holes.
Description
Technical field
The present invention relates to bridge cornice decorative panel welding method, be specifically related to Urban Road-Highway Bridges and cornice decorative panel sheet metal
Reversible deformation welding method.
Background technology
In science of bridge building, web both sides are equipped with cornicing the most outside, particularly in Urban Road-Highway Bridges.In order to whole
Body is attractive in appearance, typically arranges decorative panel below cornicing, and decorative panel is typically by thickness steel plate cutting welding between 4mm-8mm
Become.Wherein decorative panel welding fabrication and important, relates to the attractive in appearance of whole bridge.All can in the operation such as steel plate cutting, splicing
Produce bigger deformation: because relatively thin and the too high meeting of temperature cause decorative panel uneven after decorative panel cuts；And because weld seam is subject to
Thermal contraction, can make decorative panel arch camber, and the later stage processes time-consuming and difficulty is bigger.Operate decorative panel and tabula edge of a wing weldering of cornicing at ordinary times
Connecing, inside can only be with angle steel part spot welding because of narrow space, and last weld seam bulge occurs after will causing decorative panel welding, depression
Etc. problem.My company's ring road in main road, Changfeng engineering is more, and decorative panel deformation process of cornicing consumes a large amount of manpower and materials, because of
This is necessary to take a kind of scientific and reasonable and practical welding method, enables engineering to be smoothed out.
Summary of the invention
For above-mentioned technical problem, it is an object of the invention to provide a kind of bridge and cornice decorative panel welding method, the party
Method solves the steel plate problem on deformation when cutting, welding, meets and produces needs, improves production efficiency.
For achieving the above object, the technical solution used in the present invention is:
A kind of bridge cornices decorative panel welding method, it is characterised in that it comprises the following steps:
Step one, according to specific needs steel plate materials A is cut into required decorative panel B and C；
Step 2, use iron hammer to tap release decorative panel B and C internal stress in decorative panel B and C surrounding, smoothed；
Step 3, decorative panel B and C of smoothing uses low-voltage current carry out layout welding, then welding position is used iron hammer
Tap weld seam release sheet material internal stress to be smoothed；Described low-voltage current refers to voltage 23-25V and electric current 180-200A；
Plug welding hole is offered at step 4, the position being connected with angle steel and the edge of a wing of cornicing on decorative panel B and C, will dress by plug welding hole
Plaque B and C is welded and fixed with angle steel and the tabula edge of a wing of cornicing.
Described decorative panel B and C is rectangle, and a wherein length of side of decorative panel B and C is equal, and decorative panel B and C is equal
Limit be welded to each other.
The invention has the beneficial effects as follows: the bridge of the present invention cornice decorative panel welding method solve steel plate cutting, weldering
Problem on deformation when connecing, meets and produces needs, improves production efficiency.1, described method is simple, it is easy to operation；2, add plug welding hole to prevent
The welding deformation that only decorative panel surrounding weld seam causes, reversible deformation effect is ideal, reduces the input of personnel；3, later stage school is reduced
Positive quantity, drastically increases production efficiency.

Detailed description of the invention
In order to be more fully understood that the present invention, below in conjunction with embodiment and accompanying drawing, technical scheme is done further
(as shown in figures 1-8) is described.
A kind of bridge cornices decorative panel welding method, it is characterised in that it comprises the following steps:
Step one, according to specific needs by steel plate materials A(i.e. thickness steel plate between 4mm-8mm) cut into required dress
Plaque B and C；
Step 2, use iron hammer to tap release decorative panel B and C internal stress in decorative panel B and C surrounding, smooth and (decorating
Because of relatively thin after plate cutting, the too high meeting of temperature causes decorative panel B and C injustice)；
Step 3, decorative panel B and C of smoothing uses low-voltage current carry out layout welding, then welding position is used iron hammer
Percussion weld seam 1 discharges sheet material internal stress and is smoothed (because of weld seam heat shrinkable, can make decorative panel arch camber)；Described low-voltage electricity
Stream refers to that voltage 23-25V and electric current 180-200A(steel plate materials A is the thinnest, and electric current easily punctures steel plate materials A too greatly)；
Plug welding hole 2 is offered at step 4, the position being connected with angle steel D and the edge of a wing of cornicing on decorative panel B and C, will by plug welding hole 2
Decorative panel B and C and angle steel D and the tabula edge of a wing of cornicing are welded and fixed.
Described decorative panel B and C is rectangle, and a wherein length of side of decorative panel B and C is equal, and decorative panel B and C is equal
Limit be welded to each other.
The Application Example being only the present invention described above, can not limit the right model of the present invention with this certainly
Enclose, the equivalence change therefore made according to scope of the present invention patent, still belong to protection scope of the present invention.
