Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a combined foundation construction frame for civil engineering. Background Technology

[0002] In the field of civil engineering construction, foundation construction scaffolds are an important tool to ensure construction safety and efficiency. They are used to allow workers to stand upright and carry out construction operations after foundation excavation.

[0003] However, traditional foundation scaffolding is mostly a fixed design, with its support height determined at the factory, making it impossible to flexibly adjust according to actual construction needs. This leads to construction workers having to frequently hoist and replace scaffolding of different heights when dealing with foundation trenches of varying depths to meet construction requirements. This replacement operation is not only time-consuming, but also, because the height of fixed scaffolding is not adjustable, construction workers may have to use unsuitable scaffolding when the depth of the foundation trench changes, thus increasing construction risks.

[0004] Therefore, in order to solve the problem of adjusting the construction height of the foundation construction frame, this utility model proposes a new design scheme for a combined foundation construction frame for civil engineering. Utility Model Content
