Description

Technical Field

[0001] This invention relates to a template, specifically a concrete building template for civil engineering and its application method. Background Technology

[0002] The role of concrete formwork in civil engineering is mainly reflected in the following aspects: 1) Ensuring structural geometry: Through precise panel design, formwork ensures that the shape, size, and position of concrete structures and components meet design requirements, avoiding structural deviations caused by construction errors. 2) Bearing construction loads: Formwork must possess sufficient strength, rigidity, and stability to withstand the self-weight of concrete, construction loads, and lateral pressure during pouring, preventing structural deformation or collapse. 3) Controlling construction quality: Formwork provides a stable forming environment for concrete hardening, ensuring the structural appearance quality, such as surface flatness and verticality. 4) Improving construction efficiency: Formwork typically adopts a tool-like design, with simple construction and multiple reuses, significantly accelerating construction progress and reducing project costs.

[0003] Existing concrete formwork for civil engineering projects has several shortcomings. First, it cannot monitor pressure and temperature parameters in different zones and adjust the pressure and temperature in real time according to the characteristics of the concrete solidification process. Second, it cannot quickly demold the concrete slab after it has been formed.

[0004] Therefore, the known concrete building formwork has all the aforementioned inconveniences and problems. Summary of the Invention
