Description

Method for preventing diaphragm plate from deforming during machining

Technical Field

The invention relates to the technical field of diaphragm plate processing, in particular to a method for preventing diaphragm plate processing deformation.

Background

At present highway steel bridge preparation processing need make the cross slab, and at the in-process of processing the cross slab, the support is improper often can appear, leads to the cross slab to warp because of self gravity, and simultaneously, when welding manhole ring, the inhomogeneous heating after welding also can lead to the cross slab to warp, has seriously influenced the processingquality of cross slab, consequently, this application provides one kind and prevents cross slab processing deformation method.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: aiming at the existing problems, the method for preventing the diaphragm plate from being deformed is provided, the deformation caused by self gravity and welding in the diaphragm plate machining process can be effectively prevented, and the machining and using quality of the diaphragm plate is ensured.

The technical scheme adopted by the invention is as follows: the utility model provides a prevent diaphragm plate processing deformation method adds man-hour to the diaphragm plate, sets up a rectangle frame platform in the below of diaphragm plate, the diaphragm plate is placed on rectangle frame platform, the manhole region on the diaphragm plate is located the rectangle region of rectangle frame bench, be provided with the billet on two long mesa of rectangle frame platform, the length of billet is the same with the long edge length of manhole, and the billet is parallel with the long edge of manhole, the lower terminal surface of diaphragm plate all contacts with the upper portion of rectangle frame platform and the upper portion of billet for diaphragm plate length direction's part forms an inclined plane, follows the edge welding manhole circle of manhole again, and before the welding, the contained angle between the manhole circle that the long edge of manhole corresponds and the part of diaphragm plate length direction is the obtuse angle.

According to the method for preventing the diaphragm plate from being deformed in the machining process, the thickness of the steel bar is 4 mm.

According to the method for preventing the diaphragm plate from being deformed, the horizontal distance between the steel bar and the long edge of the manhole is within the range of 5-10 mm.

According to the method for preventing the diaphragm plate from being deformed, the horizontal distance between the steel bar and the long edge of the manhole is 7 mm.

According to the method for preventing the diaphragm plate from deforming during processing, when the manhole ring is welded, the manhole ring at the long edge of the manhole is welded symmetrically, and then the manhole ring at the short edge of the manhole is welded symmetrically.

According to the method for preventing the diaphragm plate from being deformed during machining, four supporting columns are fixedly arranged at the lower part of the rectangular frame platform.

Compared with the prior art, the beneficial effects of adopting the technical scheme are as follows: the invention can effectively prevent the diaphragm plate from deforming due to self gravity and welding in the processing process, and ensures the processing and using quality of the diaphragm plate.
