Temporary supporting structure for beam formwork installation

The invention discloses a temporary supporting structure for beam formwork installation. The temporary supporting structure comprises an installation plate, a fixed plate, a movable plate and a bottomplate, wherein the installation plate is provided with a bottom supporting mechanism and a side face supporting mechanism; the bottom supporting mechanism comprises a supporting plate and an angle adjusting rod; and the angle adjusting rod is rotationally connected with the installation plate and the supporting plate. During use, a motor drives a pull rod to rotate, the movable plate moves alongthe pull rod, accordingly, the height position of the installation plate is adjusted, and the supporting plate can stably support the bottom plate. A torque wrench is matched with a bolt head to enable the angle adjusting rod to rotate, a worker can conveniently adjust the angle of the supporting plate relative to the installation plate, the supporting plate can better fit bottom plates of different radians, and the suppor
