The usage habits and frequency of Film faced plywood in the Concrete building industry
It is said that there are significant differences between the north and south, both in terms of dietary and cultural habits. Today, we will talk about the usage habits of Film faced plywood in the north and south.
Film faced plywood
1、 Housing and bridge projects in the area south of the Yangtze River
1. For projects that do not require high requirements for the surface smoothness and flatness of concrete forming, pine eucalyptus red formwork Grade Film faced plywood is generally used as the top plate to reduce the cost of use. The top plate usually takes at least 7 days to remove, so projects that are slightly ahead of schedule will need to prepare several sets of top plates;
Buildings with less than 30 floors require a minimum of 10 uses of the pine eucalyptus red template, which can meet the requirements; If only 3 sets of templates are used for the roof of a building with more than 30 floors, the use of Film faced plywood must reach about 15 times. The pine eucalyptus laminated board can meet the requirements;
3. Wall panels and column formwork Grade Film faced plywood can generally be removed in three days, making turnover faster. Therefore, the use of pine eucalyptus red formwork Grade Film faced plywood for wall panels and column formwork Grade Film faced plywood can increase turnover by more than 5 times compared to top panels. The pine eucalyptus laminated board can be used as the top plate for 15 times, as the wall panel and column formwork Grade Film faced plywood for at least 20 times, and as the plastic covering formwork Grade Film faced plywood for more than 30 times. Therefore, if it is a high-rise building, the general construction party will choose pine eucalyptus laminated board or plastic covering formwork Grade Film faced plywood for the wall panel and column formwork Grade Film faced plywood , which can reduce costs.
Template overlay
2、 Housing construction projects in areas north of the Yangtze River
1. Poplar red templates with a turnover of less than 10 and melamine coated poplar boards with a turnover of less than 30 layers are commonly used;
If only 3 sets of templates are used for the roof of a building with more than 30 floors, the most commonly used is the phenolic resin poplar laminated board that has been rotated 15 times, which is purchased more frequently in Langfang, Shandong and Anhui provinces;
3. Phenolic glue laminated board and triamine glue poplar laminated board can be used for wall panels and column molds, with a turnover of more than 20 times. Plastic coated templates can also be used for turnover of more than 30 times.
In summary, the southern region mainly uses red templates and overlay templates combined with pine and eucalyptus, while the northern region tends to use poplar boards. This is actually related to the weather, because the weather in the south is humid, and poplar boards will become moldy and deformed when they come into contact with water, which is not suitable for poplar boards, resulting in differences between the north and south.
