Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, and particularly relates to a portable construction platform. Background Technique

[0002] The construction platform is an important facility indispensable in the construction process. It provides a stable working space and safety protection for construction workers, helps construction workers carry out construction operations at high altitudes, and ensures the safety of construction. There are many types of construction platforms. The patent with the patent publication number CN213015294U discloses a construction platform that is easy to move. Although the construction platform mentioned in the above patent can help construction workers carry out construction operations at high altitudes, it has the problem of large volume and inconvenient transportation. When it is necessary to transport the construction platform to different regions, the construction platform mentioned in the above patent often requires a large transport vehicle for transportation. In the current market, in order to facilitate transportation, there are also assembled construction platforms.
