What is the reason for the less use of wood formwork during construction?
1. The wood construction template is unstable after water expansion, resulting in a series of problems such as rubber layer loss effect, stratification, corner tilt, template deformation and so on;
2. Exposure, especially after water contact, is the most important factor of template deformation and the main cause of angle stratification;
3. The raw data, glue quality and pressure size in the thermal pressing process are also the main reasons for the stratification of the later template;
4, formwork in the contact of cement, concrete and other corrosive materials, and the maintenance of incorrect formwork to form corrosion, Angle and concrete pulp contact, resulting in stratification phenomenon;
5. In the installation process, the level of workers is also a very important factor, random sawing, cutting, violent demolition, violent strike, and management personnel did not optimize the template planning, no number processing, etc., these are also the factors leading to the decline in the number of template turnover;
6. The formwork and concrete are contacted for too long, the bond is too tight, and the mold disassembly is difficult, resulting in the tear of the formwork surface layer.
In summary, the non-standard structure caused damage to the surface layer of the template, so that the water absorption, instability, warping, tearing, stratification, deformation caused by the template, directly leading to the reduction of the template. The amount of the template turnover rate. In the future for a long time in the future, wooden building formwork will also be dominant in the template market, we Guangxi building formwork manufacturers can do, is nothing more than control product quality, research the process of wooden formwork processing and manufacturing in the use of template progress.
