Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to an adjustable support for civil engineering construction. Background Art

[0002] The support also refers to "scaffolding", which is a term in the construction industry and specifically refers to the temporary support erected when building a building. This support will be removed as the building is completed. The support is an indispensable construction equipment during the construction process and provides assistance for the operation of workers. However, when the existing support is used for repairing and painting the building wall, substances such as cement need to be used, but it requires the cooperation of ground personnel to transfer it to the operator on the support. For heavier objects, it is easy to be dangerous during the transfer. And in some building construction sites, there may be a situation where the support is used on an inclined ground. Obviously, under such conditions, most supports cannot keep the support platform horizontal, which is not conducive to the installation of the support. Content of the Utility Model
