Secondly, the existing building construction load-bearing frames have certain defects. Tools and building materials on the construction site ground cannot be quickly transferred from low places to high places on the load-bearing frames, and require manual handling, which results in low work efficiency. However, during the use of the construction load-bearing frame, the working standing area and its construction range are very limited and fixed. It is impossible to expand the construction range at high places. It is necessary to re-switch the working position of the load-bearing frame at lower places, which affects the impact to a certain extent. When it comes to construction efficiency.

After the construction load-bearing frame is placed, the problem of instability occurs. It is often necessary to put something on it to keep it stable. This is not only troublesome, but also has certain safety hazards and poor usability, so it is necessary to improve it.
