Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to the field of concrete column corner protection technology, specifically an adjustable and modular concrete column corner protection device. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called the "construction site" or "building site."

[0003] Currently, at construction sites, concrete column corner protection is typically achieved using concrete column corner protection strips. These strips are usually made of KT board and are attached to the concrete column using double-sided tape. However, this method often presents several problems. For example, long-term exposure to outdoor or harsh environments can cause the KT board to age and lose its protective effect. Ordinary double-sided tape can also cause the KT board to peel off over time. Strong double-sided tape can damage the KT board when it is peeled off, making it unusable. Furthermore, strong double-sided tape can leave residue on the concrete column, which is difficult to clean.

[0004] Therefore, it is desirable to provide a concrete column external corner protection device that is not easily damaged, requires no adhesive, is easy to install and dismantle, and can be reused. Utility Model Content
