The utility model relates to the technical field of building wall waterproof structure, specifically is a kind of wall flashing element connecting structure, including wall, the horizontal purlin of being located in wall upper and the sandwich panel being connected with horizontal purlin, the outside of wall is provided with outer decorative layer, the bottom end of sandwich panel is connected with the "Z" shape flashing support, the end of flashing support away from sandwich panel is connected with flashing plate, and the upper end of flashing plate is connected with flashing support by fastener, and the bottom end of flashing plate extends to the outside of outer decorative layer. By first flashing support installation in the bottom end of sandwich plate, and flashing plate can be in the size measurement when wall starts to build, after measuring, it is processed again by factory, to reduce error, and after wall is completely built, it is installed again, since the installation position of flashing support and flashing plate is in the outside of wall, the problem that installation is inconvenient due to insufficient operation space is avoided.

This invention provides a conveniently maintained positioning presser foot, comprising a presser foot bracket, a connecting block, a presser foot plate, and a limiting baffle. The connecting block is rotatably connected to the top of the presser foot bracket via a rotating shaft, and a spring is provided between the presser foot bracket and the connecting block. The bottom of the presser foot bracket has a mounting groove, and the top of the presser foot plate is fitted into this groove. A T-pin is provided on one side of the limiting baffle, and a rotation limiting hole is opened on the presser foot bracket. The T-pin passes through the rotation limiting hole, allowing the limiting baffle to be rotatably connected to the presser foot bracket. A spindle is located above the side of the presser foot bracket closest to the limiting baffle, and a torsion spring is fitted on the spindle. The two ends of the torsion spring are fixed to the presser foot bracket and the limiting baffle, respectively. This invention, by providing a mounting block on the top of the presser foot plate, utilizes the elastic deformation of the material to make the presser foot plate detachable, facilitating replacement and avoiding the inconvenience of replacing the entire presser foot assembly due to wear, thus reducing replacement costs.
