Research on the construction technology of plastic formwork
The core tip: the plastic formwork support system sets the view of large steel templates and the wood templates are easy to support and flexible.
1. Process principle of plastic formwork
The plastic formwork support system has the advantages of large steel formwork and wood formwork, which is easy to support and flexible. The splicing of plastic formwork can be directly fixed to the wooden square by iron nails (see figure l, figure 2). According to the size of concrete members, the size of various models can be combined in the longitudinal and arbitrary direction, and the construction is convenient, and the concrete forming size can be more accurate by using special clamp. Through the use of plastic templates, the concrete appearance quality can be guaranteed, the construction operation is more convenient than steel templates, wood templates, bamboo templates.
Second, low foaming multi-layer plastic building template production process and operation points
The production process and operation points of low-foamed multi-layer plastic building templates belong to the product patent and have been certified by scientific and technological achievements. The process flow of the plastic building formwork is shown in figure 3.
Open mode:
1. Control the time of mold removal. When the concrete is completely set, the concrete will be separated from the template automatically and the process will be faster and easier.
2. The disassembly template must have the demolition order signed by the construction technology department.
3. The demolition of the bottom die shall be carried out in accordance with the requirements of gb5020204-2002 construction quality acceptance of the concrete structure construction. The working class group shall make the application for removal of the application for approval by the technical director of the project department.
4. The work of the formwork shall follow the support of a working class group to perform the operation of the supporting module and the module, and shall follow the principle of the support of the dissection and lateral support of the bracket and the vertical support.
5. Clean the working face after the plastic template is removed, no ash and other garbage, and the surface of the concrete shall not be brushed and removed.
Materials and equipment
Material preparation: low foaming multi-layer plastic building template, channel steel, Angle steel, wood square, nail, bolt, steel bar, sponge bar.
