Their stable and safe construction scaffolds will play a role in safety protection for construction operators. At the same time, the convenience of using the construction scaffolds must be ensured. Therefore, there is a need for a construction scaffold that guarantees safety and meets the work needs of users. The invention with the publication number CN219298744U discloses a construction frame, comprising two support plates, both ends of the support plates are fixedly connected with connecting plates, and also comprises an adjustment component fixedly installed between the two connecting plates, the adjustment component comprises a threaded cylinder fixedly installed on one side surface of the connecting plate, a self-locking threaded rod is rotatably connected inside the threaded cylinder, one end of the self-locking threaded rod passes through the connecting plate, and a rotating shaft is fixedly connected to the end head of the end, a belt is rotatably connected to the outer surface of the rotating shaft, one end of the rotating shaft is fixedly connected to a limiting ring, climbing frames are fixedly installed on the upper surfaces of the two support plates, connecting plates are welded to the upper surfaces of the two climbing frames, and a bidirectional telescopic plate is fixedly installed between the two connecting plates; In the above technical solution, by holding the power-assisting handle, the rotating shaft is driven to rotate, thereby causing the belt to rotate, even if the rotating shafts installed at both ends of the support plate rotate at the same time, thereby driving the two self-locking threaded rods to rotate simultaneously inside the threaded barrel, and the two self-locking threaded rods are respectively engaged with the threaded barrel at the same time, and the length of the self-locking threaded rod extending out of the threaded barrel is adjusted, that is, the distance between the two support plates is adjusted, and the two-way telescopic plate is driven to be stretched or contracted, so that the length of the two-way telescopic plate can be adjusted, that is, the support length of the construction frame is adjusted, and the support area for the workers' work is increased or reduced. It can be adjusted according to the number of workers who need to work on the construction frame, so that the workers have space to stand and do not need to crowd each other to cause the risk of falling; however, although the construction frame is provided with an adjustable telescopic plate to provide workers with space and no crowding, during use, since there is no fixing device at the bottom of the construction frame and the workers need to walk back and forth on it when working, it will still cause the construction frame to shake, which is very unsafe, and the material accessories needed in the work process cannot be transported from the bottom in time, and going back and forth to get the materials and then going up to work not only wastes time but also increases the labor intensity of the workers.
