Abstract
Изобретение относится к строительству и может быть использовано в железобетонных каркасах многоэтажных зданий и сооружений. Стык сборных колонн включает концевые участки 1 и 2 стыкуемых звеньев колонны. Участки 1 и 2 содержат оборванные у торцов стержни 3 и сварные сетки 4. На плоских торцах стыкуемых звеньев колонны посредством анкеров 5, количество которых определено расчетом в виде арматурных коротышей, прикреплены торцовые пластины 6. Торцовые пластины 6 звеньев 1 и 2 колонны объединены посредством шпилек или анкеров 12 крепежными 10 и регулировочными гайками 11. К торцовым пластинам 6 со стороны стыкового зазора 8 прикреплены компенсаторы в виде стальных листов 15. Между компенсаторами 15 на оси колонны размещена деформируемая центрирующая прокладка 14, выполненная из мягкой стали. Размеры прокладки 14 приняты такими, чтобы при действии полной расчетной проектной нагрузки на колонну напряжения в прокладке 14 превышали расчетный предел текучести, но были меньше 0,85R, где R- расчетное сопротивление стали по прочности на сжатие. Компенсаторы 15 выполнены из стали по прочности, превышающей прочности стали прокладки 14. Наибольший размер каждой стороны в их плоскости не должен превышать ширину прокладки 14 на величину более 3,0t в каждую сторону от граней прокладки 14 в исходном состоянии, где t - толщина листа компенсатора 15. Для наиболее эффективного восприятия бетоном сжимающих напряжений у торцов стыкуемых звеньев 1 и 2 колонны не менее половины анкеров 5, прикрепленных к пластинам 6, сосредоточено у оси колонны и размещено параллельно оборванным стержням 3 звеньев колонны. Способ устройства стыка обеспечивает включение в работу стыка под нагрузкой шпилек или анкеров 12The invention relates to the construction and can be used in the reinforced concrete frames of high-rise buildings and structures. The junction of prefabricated columns includes end sections 1 and 2 of the joined links of the column. Sections 1 and 2 contain rods 3 torn off at the ends and welded mesh 4. At the flat ends of the abutting links of the column by means of anchors 5, the number of which is determined by calculation in the form of rebar, end plates 6 are attached. or anchors 12 fastening 10 and adjusting nuts 11. To the end plates 6 from the butt gap 8 are attached compensators in the form of steel sheets 15. Between the compensators 15 on the axis of the column is placed a deformable centering p okladka 14 made of mild steel. The dimensions of the gasket 14 are taken such that under the action of the full design design load on the column, the stresses in the gasket 14 exceed the calculated yield strength, but are less than 0.85R, where R is the design steel resistance to compressive strength. Compensators 15 are made of steel for strength greater than the strength of steel of the gasket 14. The largest size of each side in their plane should not exceed the width of the gasket 14 by more than 3.0t in each direction from the edges of the gasket 14 in the initial state, where t is the thickness of the compensator sheet 15. For the most effective concrete perception of compressive stresses at the ends of the joined links 1 and 2 of the column, at least half of the anchors 5 attached to the plates 6 are concentrated along the axis of the column and placed parallel to the dangling rods of the 3 links of colo nna The method of the joint device ensures the inclusion of the joint under the load of studs or anchors 12
