Description

technical field [0001] The invention relates to a box body for building construction, in particular to a folding box and its application. Background technique [0002] In the current building construction, various box-shaped structural parts need to be used, but most of the box-shaped structural parts on the market are assembled from panels, which cannot be folded, which makes storage and transportation more troublesome. [0003] With the acceleration of urbanization and the rapid increase of urban infrastructure projects, it is necessary to use a large number of pile foundations to improve the safety factor of various buildings. An important part of testing whether various piles are qualified is loading inspection. The load is usually prefabricated concrete, concrete transportation Pile foundation inspection and hoisting take up 70% of the time and 50% of the cost of the pile foundation inspection work; taking a 500-ton pile and inspection as an example, it is normally allo...
