Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a rotatable universal steel guide beam. Background Art

[0002] With the rapid development of the national economy, the national infrastructure construction has made great strides forward, and a large number of bridge constructions have sprung up one after another. Steel bridge construction has been widely used in the construction of cross-river and cross-line bridges due to its short construction period and simple construction process. The installation and construction forms of steel structure bridges are becoming more and more diversified. When the on-site installation conditions of steel beams are good, the construction site can be leveled and hardened, and a crane can be used for in-situ installation; when the on-site installation environment is relatively harsh (such as crossing rivers, gullies, and roads, and traffic diversion is impossible), the top-pushing construction method is required for on-site installation of steel beams.

[0003] Whether it is a walking-type jacking or a dragging-type jacking installation, the steel guide beam is installed in the forward direction of the overall steel beam jacking. The steel guide beam crosses the upper pier in advance to support the steel beam to cross, avoid the main beam from deflecting and overturning, and ensure the safety of the steel beam jacking construction. Steel beams are of various forms, with different cross-section types, widths, and heights. The corresponding steel guide beams are also very different in size and form, resulting in conventional steel guide beams being mostly one-time investments. The processing and production of steel guide beams is labor-intensive and material-intensive, which not only affects the overall progress of the jacking construction, but also greatly increases the cost of construction measures. Therefore, a universal steel guide beam that can be turned over is needed. Utility Model Content
