Embodiment Construction

[0021] In order to better understand the present invention, below in conjunction with embodiment and accompanying drawing, technical scheme of the present invention is described further (as Figure 1-8 shown).

[0022] A bridge cornice decorative plate welding method is characterized in that it comprises the following steps:

[0023] Step 1. Cut the steel plate material A (that is, the steel plate with a thickness between 4mm and 8mm) into the required decorative plates B and C according to specific needs;

[0024] Step 2. Use a hammer to release the internal stress of decorative panels B and C around the decorative panels B and C, and level them (after the decorative panels are cut, the decorative panels B and C will be uneven because they are thin and the temperature is too high) ;

[0025] Step 3. Use low-voltage current for imposition welding of the leveled decorative panels B and C, and then use a hammer to hit the weld 1 on the welded part to release the internal stres...

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 [0001] The invention relates to a welding method for a bridge cornice decorative plate, in particular to a method for anti-deformation welding of a thin steel plate for an urban highway bridge cornice decorative plate. Background technique [0002] In bridge engineering, overhangs are generally provided on both sides of the outer web, especially in urban highway bridges. For the sake of overall beauty, decorative panels are generally arranged under the overhanging eaves. The decorative panels are generally cut and welded by steel plates with a thickness between 4mm and 8mm. Among them, the welding and forming of the decorative plate is extremely important, which involves the beauty of the entire bridge. Large deformation will occur in steel plate blanking, splicing and other processes: after cutting the decorative plate, the decorative plate will be uneven due to its thinness and high temperature; Sometimes and more difficult. Usually, the decorative panel...
