Big mould of steel

Produce contradiction and need the on -the -spot trompil of big mould of steel to cause the problem of the downgrade of big mould of steel and concrete with split bolt to built -in fitting among the prior art, the utility model provides a big mould of steel and preparation, application method, big mould of steel is last to be equipped with a plurality of split bolt holes that are used for setting up split bolt, the top in last every the split bolt hole of big mould of steel is equipped with one the 2nd split bolt hole, perhaps the below in every split bolt hole is equipped with one the 2nd split bolt hole, when consequently using the fixed big mould of steel of split bolt, can choose one wantonly in an adjacent split bolt hole and the 2nd split bolt hole, can effectively avoid the position with the built -in fitting interference, thereby it overlaps the problem of interfering promptly with the split bolt position to have solved the built -in fitting at big mould of steel preprocessing in -process, avoid that
