Abstract

Изобретение относится к строительству и предназначено для использования в железобетонных каркасах многоэтажных зданий и сооружений при стыковке элементов сборных колонн. Предлагаемый стык сборных железобетонных колонн (фиг. 1) включает концевые участки нижней 1 и верхней 2 колонн. Концевые участки колонн содержат стержни 3 продольной арматуры, поперечную в виде хомутов 4 и косвенную арматуру в виде сварных сеток 5. На торце верхней 2 колонны закреплены закладные детали в виде стальных листов 6. Крепежные шпильки 7 с винтовой нарезкой закреплены в угловых нишах 8 верхней 2 колонны посредством крепежных 9 и юстировочных 10 гаек к стальным листам 6. Межторцовый зазор заполнен бетоном 11 и косвенной арматурой в виде сварной сетки 5. У торца нижней 1 колонны по углам установлены стальные муфты. Каждая муфта 12 вдоль вертикальной оси снабжена отверстием 13 с резьбой, и закреплена в бетоне посредством анкерных стержней 14, прикрепленных к ней на сварке. Шпильки 7 понизу жестко закреплены на резьбе 13 в муфтах 12. Торец 15 нижней колонны 1 выполнен бетонным. Муфты 12 понизу могут иметь хвостовик 17. Муфты 12 также могут быть изготовлены заодно с крепежными шпильками 7, как единое целое. В межторцовом зазоре в предлагаемом стыке могут быть послойно размещены плоские цементно-волокнистые или асбестоцементные листы 18 с промежуточными слоями 19 полимерраствора между ними. В промежуточных слоях 19 полимерраствора для повышения несущей способности стыка может быть размещено косвенное армирование в виде перфорированных стальных листов 20. Изобретение обеспечивает сокращение металлоемкости стыка, сокращение трудозатрат при изготовлении колонн вследствие упрощения армирования.The invention relates to the construction and is intended for use in the reinforced concrete frames of high-rise buildings and structures when joining elements of prefabricated columns. The proposed joint of precast concrete columns (Fig. 1) includes the ends of the lower 1 and upper 2 columns. The end sections of the columns contain rods 3 longitudinal reinforcement, transverse in the form of clamps 4 and indirect reinforcement in the form of welded meshes 5. At the end of the upper 2 columns are embedded fixtures in the form of steel sheets 6. Fastening studs 7 with screw thread fixed in corner niches 8 upper 2 columns by means of fastening 9 and adjusting 10 nuts to the steel sheets 6. The inter-face clearance is filled with concrete 11 and indirect reinforcement in the form of welded mesh 5. Steel couplings are installed at the end of the bottom 1 column. Each coupling 12 along the vertical axis is provided with a threaded hole 13, and is fixed in the concrete by means of anchor rods 14 attached to it in welding. The studs 7 to the bottom are rigidly fixed to the thread 13 in the sleeves 12. The end face 15 of the lower column 1 is made concrete. The sleeves 12 may have a shank 17 to the bottom. The sleeves 12 may also be made integral with the fastening pins 7 as a whole. In the interfacing gap in the proposed joint, flat cement-fibrous or asbestos-cement sheets 18 can be placed in layers with intermediate layers 19 of the polymer solution between them. In the intermediate layers 19 of the polymer solution to increase the bearing capacity of the joint, indirect reinforcement can be placed in the form of perforated steel sheets 20. The invention provides for reducing the metal intensity of the joint, reducing labor costs in the manufacture of columns due to the simplification of reinforcement.
