The traditional wood templates and steel templates are gradually replaced by plastic templates. The plastic template has the advantages of light weight, simple processing technology, high repeated utilization and the like, and is increasingly widely applied.

b. notch is opened at the vertex angle of the building template to be butted, a rectangular through hole penetrating through the panel of the building template is formed in each notch, two inner sides of the rectangular through hole are inner side walls of the panel, and two outer sides of the rectangular through hole are exposed frames; a boss is arranged on the frame;
c. assembling and splicing two building templates, and enabling two notches at the vertex angles of the building templates to be in butt joint to form an axisymmetric notch;
d. wedging the manufactured connecting piece into the notch of two building templates to be butted from top to bottom, respectively inserting vertical inserting posts at two ends of the bridge seat into corresponding rectangular through holes, enabling the bridge seat to span over the frame outside the two rectangular through holes, and clamping a boss on the frame in a rectangular groove pit at the bottom of the bridge seat; the top surfaces of the bridge seat and the vertical inserted column are flush with the front surface of the building template panel, and the T-shaped edge on the bridge seat is matched with the reinforcing rib on the front surface of the building template panel;
e. the building templates to be butted are respectively spliced and butted in groups in the transverse direction and the longitudinal direction, so that the longitudinal and transverse mutual splicing of the building templates is realized.
6. The method for butt-joint connection of building templates according to claim 5, wherein in the step a, the top of the chamfer on the vertical plug is cut into the vertical plug body, and a triangular limit transition surface is formed between the top of the chamfer and the outer edge of the vertical plug; in the step b, a limiting surface is arranged at the bottom of the intersection of the two inner edges of the rectangular through hole; in the step d, after the connecting piece is wedged into the notch, the limiting transition surface at the outer edge of the vertical inserted column is clamped on the limiting surface of the rectangular through hole.
7. The method for butt-joint connection of building templates according to claim 5, wherein in the step a, an edge of a top surface of the outer expansion of the vertical inserted column is parallel to a transverse edge of an end surface of the bridge seat, and a side surface of the vertical inserted column where the edge of the top surface is located and an immediately adjacent end surface on the bridge seat form a first step surface; the other top edge of the outer expansion of the vertical inserted column is parallel to the long edge of the top surface of the bridge seat, and the side surface of the vertical inserted column where the top edge is positioned and the side surface of the bridge seat where the long edge of the top surface is positioned form a second step surface; in the step b, in the rectangular through hole, a convex block along the outer edge direction is arranged at the joint of one inner edge and the outer edge, and a step surface is formed between the side surface of the convex block and the side surface of the inner edge; the other part of the inner edge connected with the outer edge is provided with a back hook edge along the outer edge direction, and a step surface is formed between the end surface of the back hook edge and the side surface of the inner edge; in the step d, after the connecting piece is wedged into the notch, the first step surface is clamped at the step surface between the end surface of the back hook side and the side surface of the inner side, and the second step surface is clamped at the step surface between the side surface of the protruding block and the side surface of the inner side.
8. The butt-joint connection method of building templates according to claim 5, wherein in the step a, an inner edge obliquely opposite to an outer edge of the vertical inserted column forms a right-angle clamping edge at a vertex angle of the rectangular groove pit; in the step b, the boss is of a right-angle structure, and two right-angle edges of the boss are respectively positioned on two right-angle edges outside the rectangular through hole; in the step d, after the connecting piece is wedged into the notch, the clamping edges at the top angles of the rectangular grooves at the bottom surface of the bridge seat are correspondingly clamped at the inner top angles of the bosses.
