Climbing frame combination for building scaffold

The utility model discloses a climbing frame combination for a building scaffold, and relates to the field of building construction. Comprising a back plate, a guide rail and an anti-falling mechanism, one side of the back plate is fixedly connected with a supporting plate, one side of the supporting plate is fixedly connected with two connecting plates, one sides of the two connecting plates are both fixedly connected with the back plate, the guide rail is arranged on one side of the back plate, and the anti-falling mechanism comprises two movable blocks, a linkage block and a rotating wheel. By means of the design of the anti-falling mechanism, when the guide rail ascends, the movable blocks can be jacked upwards through the rotating wheels, synchronous ascending of the climbing frame along with the guide rail cannot be affected, and if the climbing frame is loosened, the movable blocks can be jacked upwards through the rotating wheels, so that the climbing frame is prevented from falling off. When the clim
