[0029] The tongue and groove structure of the both ends of the template is formed by female end connecting plate 2 and male end connecting plate 3, in the process of template assembly, the positioning strip 32 is aligned with the positioning groove 23, the positioning strip 32 is clamped in the positioning groove 23, the female end connecting plate 2 and the male end connecting plate 3 of the two templates are kept in alignment by the cooperation of the positioning strip 32 and the positioning groove 23, the position of the splicing part is self-corrected in the process of template assembly, and the panel seam after assembly is flat and free of errors; when the female end connecting plate 2 and the male end connecting plate 3 are aligned and spliced, the female end plate body 21 and the male end plate body 31 fill the gap of the splicing surface by the sealing strip 4, the sealing strip 4 is arranged at the edge of the template, and the problem of template slurry leakage is solved; the appearance of the formed concrete is improved, and the construction efficiency is improved.

[0030] The sealing strip 4 includes a mushroom-shaped sealing edge 41 and a fixing groove 42, the mushroom-shaped sealing edge 41 is connected in the sealing groove 22, and the fixing groove 42 is arranged at the both side edge positions of the mushroom-shaped sealing edge 41, the contact area of the sealing strip 4 and the sealing groove 22 is increased by the mushroom-shaped sealing edge 41, and the sealing effect of the sealing strip 4 on the gap is improved.

[0031] The female end connecting plate 2 further includes a notch clamping strip 24, the notch clamping strip 24 is arranged on the inner side of the opening of the sealing groove 22, the notch clamping strip 24 is connected with the fixing groove 42, the notch clamping strip 24 is clamped in the fixing groove 42, the sealing strip 4 is clamped tightly in the sealing groove 22, and the sealing strip 4 is prevented from falling off.

[0032] The bottom of the mushroom-shaped sealing edge 41 is provided with a sealing surface 43, and the inside of the mushroom-shaped sealing edge 41 is provided with a buffer through hole 44. The sealing surface 43 is flush with the side surface of the female end plate body 21, and abuts against the side surface of the male end plate body 31. The sealing surface 43 tightly presses the side surface of the male end plate body 31, so that the contact surface of the male end plate body 31 and the female end plate body 21 is kept sealed. The buffer through hole 44 forms a hollow structure inside the sealing strip 4, so that the sealing strip 4 generates a rebounding elastic force when the sealing surface 43 is subjected to pressure, and the cooperation between the sealing surface 43 and the contact surface of the male end plate body 31 is more tight.

[0033] The center of the splicing surface of the female end plate body 21 and the male end plate body 31 is provided with a ventilation groove 5. The same height position of the surface of the female end plate body 21 and the male end plate body 31 is provided with a ventilation groove 5.

[0035] A plurality of groups of fixed crosspieces 8 are arranged on the side surface of the template main body 1. The fixed crosspieces 8 are parallel to each other. The fixed crosspieces 8 are used as the connecting mechanism of the template main body 1 and the supporting bracket.

[0036] The fixed crosspiece 8 includes a crosspiece main body 81, a fixed clamping groove 82 and a plurality of groups of fixed holes 83. The fixed clamping groove 82 is arranged on the top of the crosspiece main body 81. The plurality of groups of fixed holes 83 are arranged on the side surface of the crosspiece main body 81. The crosspiece main body 81 can be cooperated with the external supporting bracket through the clamping force, or can be fixed with the external supporting bracket through the bolt, so as to facilitate the installation, fixation and supporting operation of the whole template.

[0037] The female end connecting plate 2 and the male end connecting plate 3 at both ends of the template main body 1 cooperate to form a tongue-and-groove structure for template splicing, and when in use, the female end connecting plate 2 and the male end connecting plate 3 are positioned in cooperation, the connecting position of the female end connecting plate 2 and the male end connecting plate 3 is sealed by the sealing strip 4, and the problems of template assembly error and pouring leakage are solved.

[0038] The above merely describes the preferred embodiments of the present application, which are merely illustrative but not restrictive. It is understood by those skilled in the art that many changes, modifications and even equivalents can be made to the present application within the spirit and scope of the present application, but all will fall within the protection scope of the present application.
