Ten working conditions for building formwork
Divide the construction area and section of the project to be built: reasonably determine the flow section of building formwork construction according to the form, characteristics and site conditions of the project structure, so as to reduce the investment of building formwork, increase the number of turnover, balance the work volume of process engineering (reinforcement, building formwork, concrete process), and ensure the project progress.

Key points of daily maintenance of pine building formwork
With the development of science and technology, pine building formwork is the most widely used building material in the construction industry and an indispensable part of building materials. However, if the storage and daily maintenance of the building formwork are not well done, it may be damaged or even broken during use, causing loss or even danger. Therefore, it is very important to do a good job in the transportation, storage and daily maintenance of building formwork.
