The invention discloses an anti-seismic support and hanger device for pipelines. The device includes supporting C-shaped steel arranged on the top and bottom of an airduct, fixing screw rods arrangedon the left and right sides of the airduct, and airduct anti-seismic lateral supports arranged on the top supporting C-shaped steel; the fixing screw rods pass through the supporting C-shaped steel arranged on the top and bottom and are tightly fixed by using I-shaped hex nuts, standard elastic washers, plain washers and pressure plates from outside to inside; the airduct anti-seismic lateral supports are fixed on the top supporting C-shaped steel through V-shaped stiffening bolts; and the airduct is fixedly connected to the supporting C-shaped steel through fixing members and full-threaded hexagonal head bolts. The device is long in service life without welding; the replacing of airduct supports is not needed when the airduct needs to be replaced; the device can be dismounted and recombined, so that the device is convenient in installation and convenient for the operation of construction workers; and the device is simple in structure and strong in practicality, so that the purpose ofimproving the deficiency of the prior art can be achieved.
