Abstract
Description
[0001] technical field
[0002] The invention relates to a rolling device, in particular to a straight thread rolling machine integrated machine. Background technique
[0003] In civil construction, rebar is steel for reinforced concrete and prestressed reinforced concrete, with a circular or sometimes square cross-section with rounded corners. Including plain round bars, ribbed bars, twisted bars. There are many types of steel bars, usually classified by chemical composition, production process, rolled shape, supply form, diameter, and use in structures. The steel bar for reinforced concrete refers to the straight or coiled steel used for reinforced concrete reinforcement, and its shape is divided into two types: smooth round steel bar and deformed steel bar. Steel bars mainly bear tensile stress in concrete. Due to the effect of the ribs, the deformed steel bar has a greater bonding capacity with the concrete, so it can better withstand the external force. Steel bars...
