Abstract
Способ полной разгрузки железобетонной консоли колонны от воздействий подкрановых балок, утратившей несущую способность, в результате коррозии бетона и арматуры, заключающийся в том, что защитный слой бетона выше уступа колонны и в промежутке между смежными подкрановыми балками и верхней частью колонны удаляют, а поверхность промывают водой, в промежутке устанавливают опорное кольцо (центратор) из стальной трубы и заполняют его мелкозернистым расширяющимся бетоном, устанавливают на центратор центральную опорную балку, выступающую своими консолями с одной и другой стороны колонны, отличающийся тем, что устанавливают анкерную балку с тыльной стороны колонны, соединяют эти балки друг с другом горизонтальными тягами с шайбами и гайками, устанавливают боковые щеки и замыкают обойму вокруг верхней части колонны, способом «снизу вверх» нагнетают мелкозернистый расширяющийся бетон в круговую щель между обоймой и колонной, при начале схватывания бетона затягивают гайки на горизонтальных тягах, дополнительно уплотняют бетон прессованием, после твердения бетона подвешивают на тягах к выступающим концам центральной балки неравноплечие рычаги управления, по обе стороны колонны, ориентируя короткие плечи под смежные подкрановые балки, не затягивая присоединяют эти плечи к подкрановым балкам домкратными болтами, работающими на сжатие, а длинные плечи их поводят под анкерную балку обоймы, и также присоединяют их домкратными болтами, концы рычагов соединяют друг с другом и образуют замкнутую рамку управления, устанавливают ее в проектное положение, а затем механизированно регулируют домкратные болты коротки� The method of complete unloading of the reinforced concrete console of the column from the effects of crane beams, which has lost bearing capacity, as a result of corrosion of concrete and reinforcement, namely, that the protective layer of concrete is removed above the ledge of the column and in the gap between adjacent crane beams and the upper part of the column, and the surface is washed with water , in the interval, establish a support ring (centralizer) from a steel pipe and fill it with fine-grained expanding concrete, install a central support beam protruding on the centralizer they are consoles on one and the other side of the column, characterized in that they install an anchor beam on the back of the column, connect these beams to each other by horizontal rods with washers and nuts, install side cheeks and close the clip around the top of the column, from the bottom up fine-grained expanding concrete is pumped into a circular slit between the holder and the column, at the beginning of concrete setting, tighten the nuts on horizontal rods, additionally compact the concrete by pressing, after hardening the concrete I suspend on the rods to the protruding ends of the central beam, unequal control levers, on both sides of the column, orienting the short shoulders under adjacent crane beams, without tightening, connect these shoulders to the crane beams with compression jack bolts, and their long shoulders lead under the anchor beam of the cage, and they are also connected with jack bolts, the ends of the levers are connected to each other and form a closed control frame, set it to the design position, and then the jack bolts are mechanically adjusted
