Description

Technical Field

[0001] The utility model relates to the field of building construction, and more particularly to a foldable construction frame. Background Art

[0002] During construction, a common tool used to achieve sufficient height is the construction frame, also known as scaffolding. It is used to support personnel and materials during the construction or restoration of a building. Construction is prone to accidents due to its high concentration of open-air and elevated work, high production volume, low degree of mechanization, and complex processes, as well as the influence of natural climate and human factors.

[0003] Existing construction frames are generally made of multiple steel pipes and fasteners. They are extremely cumbersome to assemble and disassemble, and require a lot of time and manpower. Moreover, when the construction frames are used after assembly, their height cannot be adjusted due to their fixed structure, which makes the construction frames less practical. At the same time, in order to prevent them from moving during use, most existing construction frames are not equipped with moving wheels. Therefore, when the construction frames need to be moved, they can only be carried, which reduces the overall construction efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a movable and conveniently foldable construction frame.

[0005] The foldable platform is a platform with a plurality of support columns and a plurality of cross bars arranged between the support columns and evenly distributed. The foldable platform comprises a plurality of first and second movable columns, each of which is a plurality of hooks adapted for use with the cross bars on one side and a plurality of latches adapted for use with the cross bars on the other side. The foldable platform is a platform with a plurality of support columns and a plurality of cross bars arranged between the support columns and evenly distributed.

[0006] The utility model is further configured as follows: a sliding device is provided at the bottom end of the support column, the sliding device includes a pulley arranged in the support column and a connecting rod fixedly connected to the pulley and having a diameter smaller than the inner diameter of the support column, and the connecting rod is arranged in the support column.
