Description

Technical Field

[0001] The invention relates to the technical field of cast-in-situ concrete sloping roof construction, in particular to a novel tool template for cast-in-situ sloping roof construction. Background Art

[0002] In the traditional building structure construction system, conventional sloping roof casting usually adopts the single-sided formwork method. After the bottom formwork is completed, the steel bars are tied and then cast. Although this method is simple, there are many factors that affect the casting quality. For example, the slope can only be controlled by adjusting the concrete mix ratio to control the slump and manual smoothing, and the concrete cannot be vibrated according to the conventional method, resulting in looseness. In general, the existing construction technology cannot guarantee the construction quality and is too dependent on the operating level of the construction workers. The single-sided formwork construction mainly relies on the concrete's own cohesion, the friction resistance of the formwork and the tensioning of the steel mesh to prevent the concrete from sliding down the slope. Before the concrete initially sets, the slow displacement of the concrete continues to occur, which can easily lead to loose concrete and leakage. The subsequent repair of the leak point is difficult to find, time-consuming and labor-intensive. For this reason, there is an urgent need to design a new tool-based formwork construction system for cast-in-place sloping roof construction. Summary of the Invention
