The utility model relates to a fastener-type steel pipe scaffold formwork support applicable to a skeleton reinforced concrete girder. The support is formed by erecting steel pipes with the specifications of Phi 48*3.5; all joints are connected by fasteners; the support has the specifications of longitudinally 34 spans and transversely 4 spans and has a support height of 10.3m; upright tubes have a step of 1.2m; the upright tubes have longitudinal spacings of 0.6m and have transverse spacings of 0.6m; the upper part of the support is provided with an adjustable bracket; double 70mm*150mm aluminium beams are used as girders of a bracket formwork on the adjustable bracket; the bottom of the adjustable bracket is inserted into the support to be fixed; the adjustable bracket extends out of the upright tube steel pipes by 0.2m and can be adjusted in a range of 0.2m; the skeleton reinforced concrete girder is arranged at the upper part of the support; and in the constructing process, the dead weight of concrete is loaded on the formwork and a load transferred onto the upright tubes by the formwork is half of the total dead weight load of the concrete. The fastener-type steel pipe scaffold formwork support has a safe and firm structure and is suitable to apply to a large-section and large-span skeleton reinforced concrete girder formwork supporting system.
