Problems solved by technology

Among them, recycled PVC plastic formwork and FRP formwork are both reusable formwork, but due to the strong bond between the formwork and concrete, it is difficult to disassemble, affecting the construction period, and the cost is high; Corrosion causes the formwork to be scrapped, and the weight causes high construction strength and other disadvantages; the wooden formwork is light in weight and easy to process, but it is flammable and cannot be used as a disposable formwork
[0003] In order to overcome the defects of the above-mentioned formwork, the current one-time building formwork adopts the method of superimposing light-burned powder and glass fiber cloth at intervals. The strength performance of this formwork is poor, and the manufacturing process requires high requirements, which is prone to cracks

Abstract

The invention relates to a manufacturing method of a one-off construction shuttering; wherein, the material of shuttering is magnesium chloride, magnesia and glass fibre cloth; and the manufacturing method the shuttering mainly includes following steps: firstly, magnesium chloride solution and magnesia solution which are in same weight are mixed into pasty mass; and then, the external surface of a mold is evenly coated with release agent; and then the pasty mass made by mixing the magnesium chloride solution and the magnesia solution together is coated on the release agent; after that, a layer of glass fiber cloth is covered and pressed tightly; then predetermined thickness can be obtained by repeating the processes; and under certain conditions, the mold is shaped and can be released; finally, the demoulded shuttering is kept in shade and finished and polished into products after being totally solidified. The shuttering provided by the invention has rich materials and simple manufacturing art and can effectively reduce construction cost; besides, after finishing the construction and installation, the shuttering does not need to be dismounted, thereby shortening the construction period; moreover, the shuttering is light and has high stiffness and good fireproof performance; the shuttering can not crack easily; and the external appearance of the shuttering is white, thereby avoiding the decorating construction.

Description

technical field [0001] The invention relates to a manufacturing method of a disposable building formwork in the field of building materials. Background technique [0002] In order to save materials, reduce costs, and reduce building weight, the construction industry has adopted a one-time construction formwork instead of formwork for construction, and achieved good results. At present, the formwork used in the construction industry is mainly divided into the following types in terms of materials: (1). Recycled PVC plastic formwork; (2). Steel plate formwork; (3). Glass fiber reinforced plastic formwork; (4). Wooden formwork Formwork. Among them, recycled PVC plastic formwork and FRP formwork are both reusable formwork, but due to the strong bond between the formwork and concrete, it is difficult to disassemble, affecting the construction period, and the cost is high; Corrosion causes the formwork to be scrapped, and the heavy weight causes high construction strength and ot...
