Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel trusses, in particular to a steel truss for overpass construction with good corrosion resistance. Background Art
[0002] Steel trusses refer to trusses made of steel. Steel trusses are often used as the main load-bearing components in roof structures, crane beams, bridges and hydraulic gates of industrial and civil buildings. Various towers, such as mast towers, TV towers and transmission line towers, often use spatial steel trusses composed of three-sided, four-sided or multi-sided plane trusses. During the construction of overpasses, steel trusses need to be built to bear the load.
[0003] The constructed steel trusses are generally large in size and used for outdoor load-bearing. When encountering rainy and snowy weather, the steel trusses are prone to rust, which in turn reduces the service life of the steel trusses and reduces their supporting strength, which can easily cause safety hazards. Therefore, the corrosion resistance of the steel trusses is particularly important. Traditional steel trusses often use anti-corrosion paint sprayed on the surface of the steel trusses to isolate the steel trusses from external water. However, during construction, the steel trusses are inevitably bumped by other workpieces, causing part of the anti-corrosion paint to fall off, making the part easy to rust, resulting in poor corrosion resistance of this method. Therefore, it is necessary to design and modify the steel trusses used for overpass construction with good corrosion resistance to effectively prevent the phenomenon of poor corrosion resistance. Utility Model Content
[0004] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a steel truss for overpass construction with good corrosion resistance, which has the advantage of good corrosion resistance and solves the problem that traditional steel trusses often adopt anti-corrosion paint sprayed on the surface of the steel truss to isolate the steel truss from external water, but during construction, the steel truss is inevitably bumped by other workpieces, causing part of the anti-corrosion paint to fall off, and then making the part easy to rust, thereby making this method have poor corrosion resistance.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel truss for overpass construction with good corrosion resistance, comprising a construction frame, the construction frame comprising a main support rod and a secondary support rod, the main support rod comprising a steel pipe, the surface of the steel pipe is fixedly connected with a first corrosion-resistant layer, the inner wall of the steel pipe is fixedly connected with a second corrosion-resistant layer, the secondary support rod comprises a steel rod, the surface of the steel rod and the surface of the first corrosion-resistant layer are both fixedly connected with a third corrosion-resistant layer.
[0006] As a preferred embodiment of the present invention, the first corrosion-resistant layer is cut from an aluminum alloy tube.
