Description

Technical Field

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

[0002] Architectural decoration is the abbreviation of architectural decoration engineering. Architectural decoration is a process of various treatments of the internal and external surfaces and spaces of a building using decorative materials or ornaments in order to protect the main structure of the building, improve the physical properties and usage functions of the building and beautify the building. In the process of architectural decoration, a construction frame is needed to support the construction workers, so as to facilitate the construction workers to carry out construction on the building.

[0003] The Chinese utility model patent application publication CN 221298558 U discloses a building decoration construction frame. Although it is convenient for construction workers to replace the take-out box, the construction frame often needs to be moved and its position changed during use. Most existing construction frames rely on manual movement, and a few construction frames rely on bottom rollers for movement. However, manual movement of the scaffolding requires a lot of effort, which is not labor-saving and inconvenient to move. Although the construction frame with rollers installed at the bottom is convenient to move, its fixed support capacity is greatly reduced, and it may even move during use, making the construction frame unstable and possibly causing injury to users. Therefore, there is a problem of inconvenience in moving the construction frame. In addition, in some indoor construction, a construction frame is required for high-altitude construction. Since most existing construction frames are temporarily built, it is time-consuming and labor-intensive, and the use effect is poor. Therefore, there is a problem that the construction frame is inconvenient to cope with different construction heights. In summary, the utility model has the problems of inconvenience in moving the construction frame and the inconvenience in coping with different construction heights. Utility Model Content
