Lightweight galvanized steel springboard and processing process thereof

Abstract

The invention discloses a lightweight galvanized steel springboard and a processing process thereof, relating to the fields of building construction and ship building devices. The lightweight galvanized steel springboard of the invention uses steel SGC570, the steel springboard has a reverse-concave cross section, supporting feet at both sides are in a box-shaped structure, grooves are arranged at the bottoms of the supporting feet, end plates are arranged at both ends of the steel springboard, transverse rib plates are alternately arranged on the bottom of the steel springboard, and cold-extrusion punch holes are arranged on the surface of the steel springboard. The supporting feet and longitudinal ribs of the lightweight galvanized steel springboard of the invention are formed together with the body through once cold bending and pressing, which avoids the processing defects of the product, avoids the welding strength requirement, increases the strength, ensures the sheet smoothness and improves the whole bearing capability. According to the invention, the steel thickness can be reduced to 1 / 2.4 by substituting steel SGC570 for steel Q235, thus the consumption of iron ore and the waste of energy are reduced, the needs of practical use by reasonable design can be met.

Description

technical field [0001] The invention relates to the fields of building construction and ship repairing equipment, in particular to a light-duty galvanized steel springboard used in building construction and ship repairing and its processing technology. Background technique [0002] Our country is now in a period of rapid development. The rapid development of the construction industry and the shipbuilding industry has led to the rapid industrialization of the construction field. Most of the modern construction industry and shipbuilding industry have abandoned the traditional small workshop construction equipment, such as the traditional construction industry, Most of the springboards used in the shipbuilding industry are bamboo and wooden springboards. Although new and industrialized construction equipment is used now, such as steel springboards, the technical standard of the steel springboard is still the ministerial standard (YBJ211-88) formulated in 1988, and Q235 steel is...

AI Technical Summary

Problems solved by technology

Although new and industrialized construction equipment is used now, such as steel springboards, the technical standard of the steel springboard is still the ministerial standard (YBJ211-88) formulated in 1988, and Q235 steel is used , the use of this material and standards on strength, deflection, safety performance, disassembly and assembly, product shape and other standards no longer meet the needs of the current market. Although the steel springboard prepared by using Q235 can meet the actual needs, but the plate is thick and heavy, which is not only wasteful resources, and the dismantling burden of the steel springboard is heavy

With the development of the market and industry, although new steel products appear, how to make the steel as a steel springboard and how to ensure the mechanical properties of the steel springboard are still unsolved problems in this field
