The utility model relates to a subway station construction field especially relates to a big template of steel wood combination that subway open cut station structure was used, and solve present big steel form and have recycle and be worth low, many, the high scheduling problem of maintenance cost of turnover number of times, including two vertical steelframes, two horizontal steelframes, horizontal steelframe is fixed from beginning to end with vertical steelframe and is constituted rectangle template steelframe, first location notch is offered at the interval on vertical steelframe, run through in the first location notch of every group that to set up vertical side stupefied, vertical square stupefied both ends are fixed through two first baffles and two vertical steelframes respectively, second location notch is offered at the interval on two horizontal steelframes, run through in the notch of every group second location that to set up horizontal side stupefied, horizontal square stupefied both ends are fixed through two second baffles and two horizontal steelframes respectively. Simple structure adopts on -the -spot concatenation equipment, overcomes the problem of the big template on -site Assembly of steel wood combination difficulty, has reduced workman's intensity of labour, can demolish when finishing using, and reuse, it is energy -concerving and environment -protective.
