The invention discloses a connecting structure for a fair-faced concrete template. The connecting structure comprises templates, wherein two rubber blocks are bonded on the templates which are arranged in an angle of 90 degrees; screw caps are embedded into the tips of the rubber blocks; and L-shaped connecting blocks of which the inner surfaces form an included angle of 90 degrees are provided with bolt holes which form an included angle of 90 degrees together, are not in the same plane and are opposite to screw cap holes in the tips of the rubber blocks respectively. The connecting structure has the remarkable advantages of reliable connection and long service life.
