The specification of wood square is usually 5* 10cm, which is actually not enough. The following ratio is considered as 5* 10cm.

The ratio of beam slab formwork with thickness less than 15cm to wood square is about 100㎡. Template 10~ 12m? Wood square,

For walls below 4.5m, 100㎡ template is 18~20m? Wood square.

Formwork and scaffold formed by concrete pouring can be divided into building formwork, building veneer, laminated board, double-sided film covering and double-sided film covering building formwork according to material properties. Building formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork and jumping formwork according to construction technology conditions.

Wood square component:
