This invention concept pertains to a quickly-erectable jack of all purposes, though their size and type would vary based on the purpose of the jack. Like a car jack, the quick jack would be a jack that can be erected quickly, such as in instances where it is necessary to prop up large objects, such as parts of collapsed buildings after an earthquake. Since the buildings would vary in size and height, and the damages could vary, there are a lot of things to consider when designing the quick jack. You’d also have to consider that if you shift the weight from upper floors onto something that is likely to crush someone below, this also presents a problem. However, the concept as it is having been explained in as much detail as is necessary to consider the design, and a suitable purpose has been specified.
Systems to consider would be pneumatic, hydraulic, mechanical, and chemical – such as the expansion of gasses quickly upon an element’s interaction with water or air or some other chemical.
Sizes and purposes of quick jacks could vary widely based on the purpose, weight of the payload being lifted, intended elevation height, intended elevation slope, and the size of the cross members.
Multiple quick jacks could be used to lift an entire building, or sections of an entire building. There would be a system that would control the elevation and slope of multiple quick jacks for this purpose.
