Concrete formwork demolding structure and construction method thereof
The invention relates to the technical field of concrete pouring construction, in particular to a concrete formwork demolding structure and a construction method corresponding to the demolding structure. The demolding structure sequentially comprises concrete, an isolation layer, a bubble layer and a formwork from inside to outside. The isolation layer is arranged between the bubble layer and the concrete, and adhesion between the concrete and the bubble layer is avoided; a plurality of bubbles are flatly laid on the inner surface of the formwork to form the bubble layer, and when concrete is poured, the volume of the bubbles is reduced due to pressure, and wrinkles are formed on the surface. The pressure of the concrete can press the isolation layer on the bubble layer, and bubbles of the bubble layer can form concave-convex marks on the surface of the concrete to improve the roughness of the surface of the concrete; meanwhile, the volume of the bubbles is shrunk under pressure, wrinkles are formed on the surface, the wrinkles can also form indentations on the surface of the concrete, and the surface roughness of the concrete is further improved. Bubbles expand to separate the formwork from concrete during formwork removal, so that damage to the concrete by using a crow bar for formwork removal is avoided.
本发明涉及混凝土浇筑施工技术领域，特别是涉及混凝土模板脱模结构以及脱模结构所对应的施工方法。脱模结构由内到外依次包括混凝土、隔离层、气泡层和模板；隔离层，设置在气泡层和混凝土之间，避免混凝土与气泡层发生粘连；气泡层，多个气泡平铺设置在模板的内表面组成气泡层，混凝土浇筑时气泡受压体积缩小并在表面形成褶皱。混凝土的压力会将隔离层压紧在气泡层上，气泡层的气泡会在混凝土表面形成凹凸痕迹提高混凝土表面的粗糙度；同时气泡受压体积收缩，并在表面形成褶皱，这种褶皱同样会在混凝土表面形成压痕，进一步提高混凝土表面粗糙度。拆模时气泡膨胀让模板与混凝土脱离，避免使用撬杠脱模损坏混凝土。
