Abstract

The invention discloses a method for manufacturing a high-strength railway reinforcing mesh. The method comprises the following steps that step 1, a steel bar straightening machine is utilized to straighten a steel bar, and then the steel bar is cut into segments according to the size; step 2, the segmented steel bars are added to a diluted hydrochloric acid solution to be oscillated for 2-4h andtaken out to be dried; step 3, the surfaces of the steel bars are coated with an ethyl cellulose alcohol solution and dried to obtain coated steel bars; step 4, the coated steel bars are straightenedand cut into reinforcing rods, the reinforcing rods are arranged to form a mesh structure, and connecting points of the reinforcing rods are marked; step 5, ethyl cellulose on the surfaces of the reinforcing rods at the connecting points is removed by using ethanol, and then the connecting points are subjected to abrasion cutting to form grooves; step 6, the interiors of the grooves are coated with a neoprene adhesive, assembly is performed to form a mesh structure, and the peripheries of the connecting points are welded and solidified; and step 7, a layer of high-density polyethylene film issprayed on the surface of a prefabricated steel mesh, and then illumination is performed for 1-2h to obtain the high-strength railway reinforcing mesh. The method solves the problem of corrosion of the reinforcing mesh in the concrete setting process.

Description

technical field [0001] The invention belongs to the technical field of metal materials, and in particular relates to a method for manufacturing high-strength railway reinforcement mesh. Background technique [0002] Steel mesh, also known as welded steel mesh, steel welded mesh, etc., is a mesh in which longitudinal steel bars and transverse steel bars are arranged at a certain distance and are at right angles to each other, and all intersections are welded together. The application of reinforced welded mesh in my country is still in its infancy. At present, the proportion of my country's application amount to the total amount of steel bars is less than one-tenth. In the early 1990s, welded steel mesh was listed as a key promotion project by the National Science and Technology Commission and the Ministry of Construction, and national standards and regulations were formulated. Our country's infrastructure construction is developing rapidly, and the state's investment in infr...
