Description

Technical Field

[0001] The invention relates to the technical field of large-diameter circular bridge deck processing, and in particular to a basket-shaped large-diameter circular bridge deck processing technology. Background Art

[0002] There are some structural differences between the flower basket-type large-diameter bridge deck and the conventional bridge deck. The top of the bridge deck support plate is a flat structure and the bottom is an arc-shaped structure. In addition, there are several circular holes in the middle of the upper position of the bridge deck. This circular hole structure is used for the subsequent installation of the anchor box structure. Therefore, in the process of processing the flower basket-type large-diameter bridge deck, the processing of the bridge deck is different from that of the conventional integral bridge deck. On the one hand, it is necessary to process the panel with the circular hole area separately, and on the other hand, it is necessary to ensure the strength requirements of the welding of the panel in the circular hole area. Therefore, a new processing technology is needed to solve the processing needs of the flower basket-type large-diameter circular bridge deck. Summary of the invention

The processed bridge deck is turned over and placed on the tire frame with the front side facing up, and the U-shaped ribs on the back of the bridge deck are located above the tire frame. The processed bridge deck support plate is inverted on the back of the bridge deck, and the U-shaped rib grooves and stiffening plate grooves on the bridge deck support plate correspond to the U-shaped ribs and stiffening plates on the back of the bridge deck respectively. The bridge deck support plate is fixed with tooling. After fixing, the bridge deck support plate and the bridge deck are welded to complete the overall assembly welding of the bridge deck.

[0013] Furthermore, after the overall welding of the bridge deck support plate unit is completed, stiffening ribs are welded on both side surfaces of the bridge deck support plate unit, and the two ends of the stiffening ribs are respectively welded to the back of the arc bottom plate and the bridge deck in subsequent welding.

[0014] The advantages of the present invention are:

[0015] 1) In the present invention, the bridge deck support plate is divided into several sections, and the U-shaped rib groove and the stiffening plate groove on the bridge deck support plate unit are directly cut together during cutting, thereby improving the overall processing efficiency. The bridge deck support plate unit is welded from both ends to the middle during welding, thereby improving the welding accuracy. In addition, the bridge deck is processed in sections, and the perforated panel unit area is separated out for cutting and welding, and the main panel unit is processed separately. After the two are processed, they are welded as a whole. This avoids the problem of inconvenient cutting of the overall panel and low efficiency caused by the conventional method of welding first and then cutting holes. BRIEF DESCRIPTION OF THE DRAWINGS
