Building scaffold

The utility model discloses a building scaffold which comprises a scaffold body and guardrails, the guardrails are fixedly connected to the two sides of the surface of the scaffold body, supports are fixedly connected to the two sides of the bottom end of the scaffold body, a connecting plate is rotatably connected to the interior of a middle frame of the support on one side, a plurality of cross rods are fixedly connected to a middle frame of the support on the other side, and the cross rods are fixedly connected to the bottom end of the scaffold body. And pulleys are fixedly connected to the periphery of the bottom end of the frame body. When the scaffold connecting device is used, the connecting plate, the fixing hooks and other structures are arranged, and when a plurality of scaffolds are used for working at the same time, the connecting plate can be rotated to the transverse position and is fixedly clamped to a transverse rod of another scaffold, so that two scaffolds are stably connected, and the scaff
