Why plywood is deformed

The building formwork project is a temporary support structure made according to the design requirements, so that the concrete structure and components are formed according to the specified position and geometric dimensions, maintain their correct position and bear the self-weight formwork of the building and the external load acting on it. The purpose of the formwork project is to ensure the quality and construction safety of the concrete project, speed up the construction progress, and reduce the cost of the project. However, plywood usually deforms after a period of use. What is the cause of plywood deformation? 1. Set up small steel molds, but not set up in accordance with the regulations, resulting in poor overall performance of the building. 2.
