Description

Technical Field

[0001] The invention relates to the technical field of building roof panel installation, and in particular to a device and method for installing an outer decorative panel of a large cantilevered component of a roof eave. Background Art

[0002] The building roof adopts a sloping roof, and the structure at the eaves is cantilevered outward to form a flying eaves structure. The cantilevered structure is often long, and the lower part of the eaves is wrapped with metal plates or other exterior wall decoration materials. Because the cantilever is located at the top of the building and protrudes from the structure, the construction difficulty increases. The traditional approach is to use a ground scaffolding or a cantilevered scaffolding as a working platform for decoration construction.

[0003] This method of scaffolding construction, if the structural construction and the building construction units are the same or the construction time interval is small, can still use the structural construction scaffolding as the decoration work frame. However, it is often impossible to achieve this due to reasons such as division of work surfaces, inconsistent entry times, insufficient coordination between general and subcontractors, replacement of the construction entity, etc., and it is necessary to re-erect the work platform later.
