The utility model relates to the technical field of drainage
branch pipe installation, and discloses a same-layer drainage
branch pipe installation frame which comprises a U-shaped frame, a lower arc plate is fixedly installed at the inner bottom end of the U-shaped frame, moving plates are connected to the symmetrical inner side walls of the two sides of the U-shaped frame in a sliding mode, an upper arc plate is jointly connected between the two moving plates, and the upper arc plate is located over the lower arc plate. The upper arc plate is matched with the lower arc plate, a
threaded pipe is rotationally connected into the U-shaped frame through a mounting plate, a
threaded rod is connected into the
threaded pipe in a threaded mode, and the lower end of the
threaded rod penetrates through a
pipe opening of the
threaded pipe, extends downwards and is connected with a connecting frame. According to the technical scheme, the U-shaped frame, the lower arc plate, the upper arc plate, the threaded pipe, the
threaded rod, the fixed rod, the movable plate, the driving rod, the buffer pipe, the buffer spring, the buffer rod, the buffer arc plate and other structures are matched with one another, so that the drainage
branch pipe can be fixedly installed, the damping effect on the drainage branch pipe can also be achieved, and therefore the applicability of the device is improved.
