Composite plastic plate, preparation method, template and shaping method

Abstract

The invention provides a composite plastic plate, a preparation method, a template and a shaping method, and belongs to the technical field of construction mold engineering. The invention can realize the preparation of the composite plastic plate and the shaping of the composite plastic formwork, contact the concrete through the plastic surface layer, enhance the tensile performance through the first fiber layer and the second fiber layer, and enhance the tensile performance through the mesh reinforcement layer and shear performance, reduce and avoid mold expansion or local swelling caused by the heat and expansion of concrete; and when bending is required, after cutting the reinforcing ribs, it can be easily bent through the bending groove set at the reinforced base It can form a curved surface or a corner shape without splicing, and there is no seam; when no bending is required, the reinforcing rib can avoid the stress concentration at the bending groove, thereby avoiding local deformation; at the same time, the reinforced layer of mesh reinforcement and the plastic surface The layer is a layered structure, and the materials of the plastic surface layer and the mesh reinforcement layer can be different, which is beneficial to saving resources and reducing costs.

Description

technical field [0001] The invention belongs to the technical field of architectural mold engineering, and more specifically relates to a composite plastic plate, a preparation method, a template and a shaping method. Background technique [0002] Utilizing molds (i.e. templates) to cast is the main means of controlling body shape in concrete engineering. Existing concrete templates mainly include traditional steel templates, wooden templates and bamboo plywood, and new PVC plastic templates. [0003] In the past, during the construction of substation civil concrete works, due to the heavy weight of steel formwork and high manufacturing and maintenance costs, wood formwork or bamboo plywood was often used for panels. Improper or long-term immersion in water, the turnover will not exceed 2 times, and it is easy to degumming, drumming, shelling, and cracking. When reassembling, the board seams are difficult to handle, and the thickness tolerance is not easy to grasp, resulting...
