AI Technical Summary
In existing technologies, wooden or plastic separator strips are prone to deformation or displacement during the construction of concrete protective layers, resulting in uneven separator joints, difficulty in removal, and impact on waterproofing performance and decorative effect. Furthermore, these resources are difficult to reuse.
A roof concrete protective layer expansion joint construction device using adjustable support bases and lifting components. The expansion joint is fixed by the adjustable support base and separated from the top support by the lifting component, ensuring accurate and straight positioning of the expansion joint. The expansion joint is designed as a hollow steel component to improve stability and is suitable for concrete protective layers of different thicknesses.
It achieves precise positioning and straight, aesthetically pleasing separation joints, ensures accurate control of the concrete protective layer thickness, avoids resource waste, improves waterproof performance and decorative effect, and facilitates removal and reuse.
