Exterior feature matches with framework of steel reinforcement shape.
Preferably, in order to ensure beam sections bottom plate, roof steel bar binding precision, the precise positioning card slot is uniformly arranged
Match on horizontal chassis and top plate moulding bed, and with beam sections bottom plate, roof steel bar lashing location.
Preferably, in order to meet the needs of site operation, the main body moulding bed is consistent with the quantity of segment beam forms.
Compared with prior art, the usefulness of the utility model is:It can be designed according to template system, equally by reinforcing bar tire
Frame is divided into equivalent moulding bed, and corresponding beam sections changes of section mode, sets limiting slot number and position, corresponding different template
System carries out corresponding reinforcing bar binding installation, guarantees to position the segment beam steel in multiple sections, has saved construction cost, reduces
High-altitude working safety risk, improves construction quality and effect.
