Abstract
Способ восстановления работоспособности аварийной железобетонной консоли колонны, утратившей работоспособность в результате коррозии бетона и арматуры, заключающийся в том, что механизировано на заводе металлоконструкций изготавливают сборную обойму, состоящую из швеллеров и швеллерообразных гнутых сборных элементов с соосными совпадающими отверстиями в полках и соединительных листах, удаляют защитный слой бетона (толщиной 60…75 мм) по контуру консоли, промывают очищенную поверхность, транспортируют готовые части сборной обоймы в цех, охватывают верхней частью сборной обоймы на отметке перекрытия площадки колонну, совмещают отверстия в вертикальных полках верхней части сборной обоймы и соединяют их болтами в замкнутую обойму, гарантировано затягивают гайки гайковертом, мостовым краном потягивают замкнутую обойму вверх с зазором до подкрановой балки 350…400 мм, подвешивают ее на проектной отметки на рихтующих тягах присоединяют снизу под аварийной консолью болтами к обойме наклонный фиксирующий упор и днища из листов, присоединят бетонопроводы к патрубкам обоймы, нагнетают через них в обойму способом «снизу вверх» мелкозернистый, расширяющийся бетон, а после схватывания бетона преобразуют железобетонную консоль в единую трубобетонную консоль, устанавливают под подкрановой балкой на опорные столики обоймы пару автомобильных гидродомкратов, ослабляют гайки на анкерных болтах подкрановых балок, парой гидродомкратов поддомкрачивают соединенные подкрановые балки на проектную величину Δ, затягивают и контрят гайки контргайками, полностью восстанавливают несущую способность аварийной консоли и �A method for restoring the emergency emergency reinforced concrete console of a column that has lost its operability as a result of corrosion of concrete and reinforcement, which consists in the fact that mechanically, a prefabricated ferrule consisting of channels and channel-shaped bent prefabricated elements with coaxial matching holes in the shelves and connecting sheets is manufactured a layer of concrete (60 ... 75 mm thick) along the contour of the console, wash the cleaned surface, transport the finished parts of the precast cage to ex, they cover the column with the top of the collar at the mark of overlapping the platform, align the holes in the vertical shelves of the top of the collar and bolt them into a closed collar, they are guaranteed to tighten the nuts with a wrench, with a bridge crane pull the closed collar up with a gap to the crane beam of 350 ... 400 mm , suspend it at the design mark on the leveling rods, attach an inclined fixing stop and bottoms from sheets from below under the emergency console with bolts to the cage, attach concrete pipelines to the casing nozzles, fine-grained, expanding concrete is pumped through them into the cage in a “bottom-up” manner, and after setting the concrete, the reinforced concrete cantilever is converted into a single cantilever cantilever, a pair of hydraulic jacks are installed under the crane beam on the cage support tables, the nuts on the anchor bolts of the crane gates are loosened, a couple the connected crane beams by the design value Δ, tighten and counter the nuts with locknuts, completely restore the bearing capacity of the emergency console and
