Description

Technical Field

[0001] The invention belongs to the technical field of construction, and in particular relates to a simple control device for adjusting the thickness of an underwater steel mesh protective layer. Background Art

[0002] Steel mesh, also known as welded steel mesh, is a widely used material in the construction industry. It is mainly composed of longitudinal and transverse steel bars arranged and welded at a certain distance, and has the advantages of high structural stability and uniform force. In concrete structures, the protective layer of steel mesh is a crucial component, and its thickness directly affects the durability and safety of the structure. The role of the protective layer is not only to provide effective protection for the steel bars to prevent them from being damaged by external moisture, carbon dioxide and other corrosive substances, but also to ensure the strength of the structure by evenly transferring external loads to the interior of the concrete.

[0003] Most of the existing steel mesh protective layer thickness control devices are designed for a fixed height, which makes the device lack flexibility in different construction requirements. During construction, the inability to quickly adjust the thickness can easily lead to problems with the protective layer being too thick or too thin. On the one hand, a protective layer that is too thin will reduce the corrosion resistance of the steel bars, and in severe cases may even cause concrete cracking and steel corrosion; on the other hand, a protective layer that is too thick will increase material costs and reduce construction efficiency. Therefore, there is an urgent need for a steel mesh protective layer thickness control device that can meet the needs of multiple scenarios and is simple to operate and flexible to adjust.
