Description

Technical Field

[0001] The utility model relates to the technical field of construction frames, in particular to a building construction frame. Background Art

[0002] Construction scaffolds are used in many construction projects. They are temporary facilities that play a particularly important role in building installation and construction. Their stable and safe construction scaffolds can play a role in safety protection for construction operators. At the same time, the construction scaffolds must also be easy to use. Therefore, there is a need for a construction scaffold that is safe and meets the work needs of users.

[0003] The utility model with publication number CN219298744U discloses a construction frame, comprising two support plates, both ends of the support plates are fixedly connected to connecting plates, and also comprises an adjustment assembly fixedly installed between the two connecting plates, the adjustment assembly 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 is fixedly connected to a rotating shaft at the end head, 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 two-way telescopic plate is fixedly installed between the two connecting plates;

[0004] In the above technical solution, by holding the power-assisting handle, the rotating shaft is driven to rotate, thereby rotating the belt. Even if the rotating shafts installed at both ends of the support plate rotate simultaneously, the two self-locking threaded rods are driven to rotate simultaneously inside the threaded barrel. 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 from the threaded barrel is adjusted, that is, the distance between the two support plates is adjusted, which drives the bidirectional telescopic plate to be stretched or contracted, thereby adjusting the length of the bidirectional telescopic plate, that is, adjusting the support length of the construction frame, increasing or reducing the support area for workers' work, and can be adjusted according to the number of workers required to work on the construction frame, so that the workers have enough space to stand and do not have to crowd each other, causing the risk of falling. However, although the construction frame is provided with an adjustable telescopic plate to provide workers with free space and avoid 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, the construction frame will still shake, which is very unsafe. In addition, the materials and accessories needed in the work process cannot be transported up from the bottom in time, and the workers have to go down to get the materials and then go up to work, which not only wastes time but also increases the labor intensity of the workers.
