The typical galvanized cold-rolled steel sheet with the thickness of 0.5mm, for example, the Q235B strength Z100 galvanized cold-rolled steel sheet is selected to replace the environmental protection function of a wood template material, and compared with other non-dismantling templates, the mechanical property is excellent, the dead weight is light, the material cost is lower, the excellent shaping function is realized, and the good anticorrosion and durable functions are realized. The size of each direction and the connection assembly precision of the adjacent templates 1 are less than 1.0 mm. In practice, the precision of the cutting process of the produced template reaches 0.1 mm. The splicing positions of the adjacent templates of the column and the beam can be fixedly connected into a whole by adopting a connecting piece.

The cross section of a building component such as a column, a beam, a wall and a plate is rectangular, a corner support 3 is arranged at a corner, the corner support 3 is an assembled long straight section with a right angle at the outer corner of the cross section, an assembled long straight rod square tube with a rectangular cross section is preferred, no modulus specification limitation exists, a galvanized straight welded steel tube can be typically adopted, adjacent corner supports 3 in the same direction are fixedly connected in an aligned mode through a connecting piece or a fastening piece, the corner supports are directly output by a numerical control device which is butted aiming at a design drawing of a construction target and are manufactured without a reworking site, for example, the cross section specification is 50mm in length, 50mm in width, 2mm in thickness and +/-0.5 mm in length machining error. The material is Q235B strength Z100 galvanized steel sheet. The material has the advantages of good corner positioning function, relatively low material cost, standardized reusability and good corrosion resistance and durability.

The outer side of the template 1 is closely adjacent to a face support 2, the face support 2 preferably adopts a glass fiber reinforced plastic grating plate which takes glass fiber reinforced plastics with the thickness of 50mm as raw materials, the longitudinal strip spacing of the grating is 50mm, the transverse strip spacing of the grating is 50mm, the grating is directly output by numerical control equipment which is butted according to a design drawing of a construction target and is manufactured without a construction site, and the length processing error is +/-2.0 mm.
