Description

[0002] With the development of metal material science, stainless steel composite steel plates have been gradually widely used in steel structure projects such as railway bridges and special functions. Stainless steel composite steel plates not only solve the problem of anti-corrosion and rust prevention of steel plates well, but also eliminate the pollution caused by paint coating. In order to ensure the safety of the project structure and reduce the project cost, without wasting the raw materials of stainless steel composite steel plates, it is necessary to process the stainless steel composite plates into corrugated shapes to increase the stiffness of the stainless steel composite plates under the condition of a unit plate thickness and increase the strength of the bridge structure. The first domestic steel structure aqueduct project adopted the corrugation and forming technology of large-size medium-thick stainless steel composite steel plates with an area of 21.35 m of 7000mmX3050mmX24mmm 2 and a thickness of 24 mm for the first time in China. Due to the elastic fluctuation of the corrugated plates after processing and forming, when the corrugated plates and the bottom plates (stainless steel composite steel plates) are assembled by milling the groove openings, micro-adjustments and precise assembly are required. In order to avoid the damage to the stainless steel composite plates caused by the high temperature of stainless steel thermal correction, it is necessary to adopt effective control process measures to solve the manufacturing and processing of the corrugated plate blocks on the side walls of the world-class steel structure aqueduct.

[0032] Embodiment 1:

[0033] The auxiliary tooling for assembling the stainless steel composite corrugated wall plates for bridges in this embodiment is as Figures 1 - 3 shown. The tooling is made of H-shaped steel with a cross-sectional height of 500 mm and 300 mm. Due to the large specifications and plate thickness of the stainless steel composite corrugated plate, the tooling needs to have sufficient stiffness. The base 1 is 7500 mm long and 4000 mm wide. At both ends of the base 1 in the width direction, H-shaped steel with a cross-sectional height of 500 mm is used, and in the middle length direction, "H"-shaped steel with a cross-sectional height of 300 mm is used for connection; there are "H"-shaped steel columns 4 with a height of 1200 mm and a cross-sectional height of 300 mm at the four corners. Baffles 8 and 9 are welded on the inner side of the columns 4, 50 mm and 320 mm away from the ends. On the 500 mm "H" side in the width direction at both ends of the base 1, a reference line plate 6 is welded, and a reference line 13 is drawn on the reference line plate 6 as the reference line for loading, adjustment, bar marking, and assembly. Before drawing the reference line 13, the tooling must be adjusted using a level.

[0034] After placing the stainless steel composite corrugated plate 10 on the tooling, adjust the stainless steel composite corrugated plate (the height of the corrugated plate is a fixed value) with the reference lines 13 at both ends of the tooling to determine the deviation amount and the adjustment position; install the movable crossbeam 4, and add a pressing tool 5 directly below the movable crossbeam 4. In this embodiment, the pressing tool is a jack. Add pressing points and the number of pressing points above and below the stainless steel composite corrugated plate 10 according to the deviation value to complete the precise adjustment of the corrugation of the corrugated plate by 0.5 mm to 1 mm. Compare the corrugation of the adjusted stainless steel composite corrugated plate 10 with the machined grooves on the upper cover plate 11 and the lower cover plate 12 of the stainless steel composite plate or perform machining to open grooves, so that the corrugation of the stainless steel composite corrugated plate 10 fits better with the groove shapes of the upper cover plate 11 and the lower cover plate 12.

[0035] Based on the best fit between the corrugation of the stainless steel composite corrugated plate 10 and the groove shapes of the cover plates 11 and 12, perform welding. The welding points are spot-welded on the base layer side, and the cutting line in the length direction is marked.

[0036] Remove the jack and the movable crossbeam 4, so that the assembled side wall plate can be lifted and unloaded.

[0037] If necessary, a lengthening rod 7 can be added to the pressing tool 5 to increase the stroke of the pressing tool 5.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
