step seven, binding reinforcing steel bars of the complex texture bare concrete structure on a construction site, and preparing a template for construction;
and step eight, conveying the combined template units to a construction site, assembling according to the serial numbers in sequence, and preliminarily fixing to form an integral combined template system.
2. The construction method according to claim 1, wherein the outer steel formwork system comprises an outer steel formwork, an inner lateral keel, an inner vertical keel, an outer lateral keel and an outer vertical keel, wherein the outer surfaces of the outer steel formwork are vertically crossed and equidistant to form a plurality of inner lateral keels and inner vertical keels, a plurality of outer lateral keels are arranged on the outer side of the inner vertical keel, and a plurality of outer vertical keels are arranged on the outer side of the outer lateral keels.
3. The construction method according to claim 2, wherein two ends of the inner side vertical keel are respectively provided with a transverse connection plate, the transverse connection plates are provided with bolt holes, and the upper and lower adjacent template units are connected through bolts on the transverse connection plates.
4. The construction method according to claim 2, wherein two ends of the outer lateral keels are respectively provided with a vertical connecting plate, the vertical connecting plates are provided with bolt holes, and the left and right adjacent template units are connected through bolts on the vertical connecting plates.
5. The method of construction of claim 2 wherein said outboard lateral keels are provided with a plurality of connectors, said outboard lateral keels being fixedly connected to the bent frame by said connectors.
6. The method of claim 1, wherein the glass fiber reinforced plastic lining board is made of polyester glass fiber reinforced plastic, epoxy glass fiber reinforced plastic or phenolic glass fiber reinforced plastic.
7. The method of claim 1, wherein the adhesive layer is one of epoxy glue, phenolic-acetal glue, quick setting acrylate glue, alpha-cyanoacrylate glue, or polyamino glue.
8. The construction method of claim 1, further comprising a step nine of spatially scanning the entire combined template system by using a three-dimensional scanner, calibrating the position accuracy thereof, and performing position adjustment of the template unit according to the scanning result, controlling the thickness of the reinforcement protection layer, and performing final fixation.
