[0002] Chinese patent application No. 201711450219.1 discloses a hanging and fixing device for a siphonic roof rainwater drainage system. The device includes multiple hanging components spaced apart along a horizontal pipe. The top of each hanging component is fixed to the roof structure via a connector. The lower parts of the multiple hanging components collectively suspend an energy-dissipating rod and the horizontal pipe. The energy-dissipating rod is positioned above and horizontally to the horizontal pipe. Each hanging component, from top to bottom, consists of a connecting plate, a hanging rod, a rod clamp, an intermediate connecting rod, and a pipe clamp. This invention simultaneously provides the functions of suspending and fixing the horizontal pipe of the siphonic roof rainwater drainage system and dissipating energy from pipe vibration and thermal expansion and contraction. It effectively prevents the direct impact of pipe vibration and thermal expansion and contraction on the building structure, protecting the building structure's safety and preventing deformation and displacement of the pipe system. The device features a simple structure, clear force transmission, precise positioning, strong connection, and convenient installation.
