Description

Technical Field

[0001] The utility model relates to the technical field of steel frame structures, in particular to a light steel keel with an anti-cracking structure. Background Art

[0002] Traditional wooden keels are not durable enough and are easily affected by moisture, swelling and deformation. With the rise of light steel keels, their high durability and earthquake and compression resistance are deeply loved by people and gradually replace wooden keels.

The stress generated over time will cause the keel to deform, leading to cracking of the top gypsum board. It is not only unsightly but also poses a major safety hazard. Therefore, it is very important to prevent it from cracking. Utility Model Content
