AI Technical Summary
In the construction of large LNG storage tanks, it is difficult to accurately control the thickness of the concrete cover for steel bars, especially in the construction of walls with varying thickness and uniform thickness. Conventional supports cannot ensure that the thickness of the concrete cover for steel bars is within the design range, which leads to the tilting of the steel bars and affects the construction quality.
An auxiliary support for controlling the thickness of the protective layer of the outer steel reinforcement of an LNG storage tank is designed. It adopts abutment component one and abutment component two connected by connecting screws. The spacing between the components is adjustable. The steel reinforcement is supported by a mirror structure and a U-shaped structure to prevent the steel reinforcement from tilting. The steel reinforcement tail material is used to process threads to achieve stable support.
It effectively controls the thickness of the concrete cover for reinforcing bars, ensuring it remains within the design range, improving construction quality, expanding the scope of application of the support, facilitating the adjustment of construction spacing, preventing the reinforcing bars from tilting, and utilizing waste reinforcing bars to process threads, thereby enhancing the stability of the support.
