We know that is more rain in the south, the north edge is dry, so under the condition of the two extremes of construction must be more careful, you know fangyuan mould production buildings cylindrical formwork material of wood products, if can not contact the rain for a long time, although the quality of our building formwork is stable, can short time, long steel formwork is also not line, for construction unit it is necessary to find a storage warehouse, moreover, the cylindrical wooden formwork are vertical storage, this way can save a lot of space, shard deposit is very flexible.
Before the frame column is installed, it is necessary to pop out the axis of the column and the surrounding edges on the layer first.

From the modeling of special parts encountered in the process of die support, such as bridge column parts and special arc formwork, it takes a lot of manpower and methods to realize the die support of these parts by using steel formwork.
