REINFORCED CONCRETE ELEMENT CONNECTION METHOD Russian patent published in 2009 - IPC E04B1/38 

FIELD: construction industry.

SUBSTANCE: invention refers to construction industry, and namely to construction of town underground shallow objects. Method of connecting horizontal or inclined reinforced concrete bored piles to vertical ones at underground shallow objects involves zero platform design, vertical reinforced bored piles arranged within the shallow object area, reinforced concrete plate with openings, which is arranged on the bored piles, subsequently down-going earth excavation within each layer, sub-grading at the level of the next flooring, indentation in vertical bored piles, placing some part of flooring reinforcement in indentation, and flooring concreting. In reinforcement cage of bored pile, before the latter is lowered into the well, above or below future indentation there rigidly fixed is a through element, e.g. a piece of tube with the compression strength that is not lower than compression strength of concrete taken out for indentation. Future connection points to the flooring are restricted from above and from below by filling those with easy-removable material e.g. foam plastic or foam plexus, or erection foam, etc., which is removed on the next layer.

EFFECT: reducing labour cost, and improving safe work when attaching vertical reinforced concrete elements to horizontal ones.
