Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a strength testing device for steel structures. Background Technology

[0002] Steel structures are structures made primarily of steel, typically hot-rolled steel plates, shaped steel (such as I-beams, channel steel, angle steel, H-beams, etc.), and cold-formed thin-walled steel, which are widely used in many engineering fields such as buildings, bridges, and large stadiums.

[0003] After the steel structure is fabricated, it is essential to test its strength. However, the commonly used strength testing devices have obvious shortcomings, such as the lack of auxiliary material feeding function. The materials involved in steel structure fabrication are often quite heavy, and relying on manual material feeding is not only time-consuming and labor-intensive, but also extremely inefficient. Therefore, we propose a strength testing device for steel structures. Utility Model Content

This solves the problem that common strength testing devices currently have obvious shortcomings, such as the lack of assisting in material feeding. The materials involved in steel structure processing are often quite heavy, and relying on manual feeding not only consumes a lot of time and energy, but is also extremely inefficient.
