Description

Technical Field

[0001] The utility model relates to a bottom plate scribing device for steel structure processing, and relates to the field of steel structure processing and manufacturing. Background Art

[0002] Bridge design and construction is a field involving multiple complex engineering problems, and the design of bridge alignment is particularly important. The alignment of a bridge not only affects its structural performance and aesthetics, but also directly relates to the construction difficulty and cost control. When the bridge bottom plate adopts a plate unit structure, the complexity of its design and construction will further increase.

[0003] In the design of the bridge bottom plate, if there is a horizontal curvature, it will make the assembly of the bottom plate units more difficult. The existence of the curvature means that the bottom plate units are no longer simple planar structures, but need to be designed and manufactured according to a specific curvature. Such design requirements not only increase the manufacturing difficulty, but also improve the requirements for construction accuracy.

[0004] The scribing of the assembly line of the bottom plate ribs is a key step in the construction process. In the bottom plate units with curvature, the accuracy of the assembly line scribing directly affects the stability and load-bearing capacity of the entire bridge structure. If the assembly line scribing is inaccurate, it may lead to insecure connections between the bottom plate ribs, and even cracks or fractures may occur under stress, thus affecting the service life and safety of the bridge.

[0005] In order to realize the scribing of steel structure plates, a bottom plate scribing device for steel structure processing is designed. Content of the Utility Model

The adjustable component is adjustably arranged on the horizontal pipe. The fixed bearing installation pipe is perpendicular to the horizontal pipe. The fixed bearing is fixedly installed on the fixed bearing installation pipe. A scribing space for the bottom plate is formed between the fixed bearing and the adjustable component. A scribing component corresponding to the scribing space is sleeved on the horizontal pipe.

[0008] The adjustable component includes a moving adjustment sleeve and a moving bearing mounting tube. The moving adjustment sleeve is sleeved on the cross tube, and the moving adjustment sleeve is slidably matched with the cross tube. On the moving adjustment sleeve, a moving adjustment screw is radially installed along the moving adjustment sleeve. After passing through the moving adjustment sleeve, the moving adjustment screw is movably matched with the cross tube and abuts against or moves away from the cross tube. A moving bearing mounting tube is also installed on the moving adjustment sleeve. The moving bearing mounting tube is arranged parallel to the fixed bearing mounting tube. A moving bearing is installed on the moving bearing mounting tube, and the bottom plate is placed between the fixed bearing and the moving bearing.
