[0002] During the construction of a building, the height of the building is constantly increasing, and a device that can provide a safe working platform for construction workers is required. The scaffolding can be erected according to different building heights and shapes, enabling construction workers to carry out construction operations at various height levels, such as building walls, installing doors and windows, and performing exterior wall decoration. At the same time, for some complex building structures, such as cantilevered parts and pitched roofs, the scaffolding can provide flexible support and operating space to ensure the smooth progress of construction.

[0003] After retrieval, the text of the publication number "CN221567830U" mentions "a scaffolding for building construction, including a working platform, a support frame, a ladder, and a limit lock. The working platform is detachably connected to the upper end of the support frame. A slide rail is provided inside the working platform, and both ends of the slide rail are closed. There is an opening in the middle of one side of the working platform. A pulley is provided on the ladder, and the ladder is slidably installed in the slide rail of the working platform. The pulley is in sliding fit with the slide rail. A limit lock is provided at the opening of the slide rail on the working platform. The limit lock includes a rotating block and a screw. One end of the rotating block is rotatably installed on the working platform. The rotating block contacts the end face of the ladder. A through hole is provided at the other end of the rotating block, and the screw is installed on the working platform through the through hole. When it is necessary to get on and off the scaffolding, the ladder is pulled out to the edge of the working platform and rotated downward to rest on the ground to form an inclined upward ladder, which is convenient for people to get on and off. When the scaffolding is not in use, the ladder is pulled back into the working platform, which does not occupy space and is convenient for transportation." When in use, compared with the prior art, the scaffolding for building construction of the present utility model is provided with a ladder that can slide inside the working platform of the scaffolding.
