Temporary supporting device in construction of cantilever inclined steel structure

The utility model discloses a temporary supporting device in cantilever inclined steel structure construction, and belongs to the technical field of cantilever beam installation. Comprising a fixed bottom plate, a supporting rod is arranged on the fixed bottom plate, one end of the supporting rod is rotationally connected with the fixed bottom plate, the other end of the supporting rod is used for abutting against a cantilever beam, limiting blocks are symmetrically arranged on the outer side of the supporting rod, and inclined holes with the same inclination angle as the cantilever beam are formed in the middles of the limiting blocks. The supporting rods are located in the inclined holes, the symmetrically-arranged limiting blocks are detachably connected, and limiting mechanisms used for limiting sliding of the limiting blocks are symmetrically arranged on the two sides of the fixed bottom plate. The technical scheme is used for solving the problem that the inclination angle of the cantilever beam is diffi
