The support frame is fixed in the foundation pit, the gas pipeline is fixed on the support frame, and the gas pipeline is suspended through the support frame. The existing support frame for gas pipeline installation is generally a simple clamp structure, and the gas pipeline is directly placed in the clamp. This installation method has a poor effect on the fixation of the gas pipeline, the gas pipeline has poor stability, and the construction efficiency is relatively low.

[0003] The existing patent CN202321887969.6 discloses a gas pipeline support that is easy to adjust, including a base plate, a fixing rod, an upper threaded rod and a support bracket; a screw is fixed in the middle of the upper end of the base plate, and the upper end bearing of the fixing rod is connected to the upper threaded rod, and the upper end of the upper threaded rod is threadedly connected to the support bracket; a protective support is rotatably connected to the left and right sides of the support bracket; two limit rods are respectively welded to the left and right sides of the upper end of the base plate, and a push rod is passed through the middle of the limit rod, and the push rod pushes the support bracket; the mounting frame is sleeved on the outside of the base plate; the airbag and the shock absorber are both arranged at the inner bottom of the mounting frame, and the support bracket is damped by the arrangement of the airbag and the shock absorber.
