The utility model belongs to the technical field of tunnel invert side wall and packing construction formwork, especially, relate to a realize whole template device of quick construction of inverted arch. Whole template device, include the inverted arch and fill integrative template, crane beam crossbeam, flexible roof beam, template angle adjustment mechanism, lift cylinder, flexible hydro -cylinder and crane beam longeron, the crane beam crossbeam adopts hollow structure, crane beam crossbeam both ends are inside to be equipped with flexible roof beam, flexible roof beam passes through template angle adjustment mechanism with inverted arch side wall and fill integrative template and link to each other two two crane beam longerons of parallel arrangement between the crane beam crossbeam, flexible hydro -cylinder setting is in the inverted arch and fill integrative template and the crane beam longeron between, be equipped with the lift cylinder on the crane beam longeron. The utility model discloses reduced artifical intensity, improved the efficiency of construction, degree of automation is higher, has solved because angular discrepancy that self amount of deflection of flexible roof beam produced.
