(54) СПОСОБ ГЕРМЕТИЗАЦИИ ШВОВ СБОРНЫХ ЖЕЛЕЗОБЕТОННЫХ КОНСТРУКЦИЙ(54) METHOD FOR SEAMING SEAMS OF COMBINED REINFORCED CONCRETE STRUCTURES
1one
Изобретение относитс к строительству и может быть использовано дл герметизации швов сборных железобетонных конструкций , например лотков оросительных систем , и гидротехнических сооружений.The invention relates to the construction and can be used to seal the seams of precast concrete structures, such as irrigation systems, and hydraulic structures.
Известен способ герметизации швов сбор- 5 ных железобетонных конструкций, включающий установку в шве герметизирующей прокладки 1.A known method of sealing the seams of prefabricated reinforced concrete structures, including the installation of a sealing strip 1 in the seam.
Недостатком этого способа вл етс низка герметизируюш.а способность шва Q вследствие возможности фильтрации воды по границе прокладки и бетона.The disadvantage of this method is the low sealing ability of the seam Q due to the possibility of filtering water along the gasket and concrete.
Известен также способ герметизации швов сборных железобетонных конструкций , включающий предварительное нанесение на поверхности стыкуемых элементов 5 грунтовочного сло на основе битумно-каучуковой композиции и основного герметизирующего сло на основе битума, каучука, вулканизирующей добавки, органического растворител и минеральных наполните- 20 лей 2.There is also known a method of sealing the seams of precast concrete structures, including the preliminary application on the surfaces of the abutting elements 5 of a primer based on a bitumen-rubber composition and the main sealing layer on the basis of bitumen, rubber, a vulcanizing additive, an organic solvent and mineral fillers 20.
При завершении процессов вулканизации основной сло способен самосто тельно сохран ть приданную форму в широком диапазоне температур (до -flOO°C). Процесс вулканизации при повышенной температуре воздуха, например в услови х Средней Азии, длитс 10-15 сут, а сразу же после нанесени этого сло он имеет теплостойкость 50°С, что обуславливает вытекание состава из шва, особенно вертикального. Поэтому дл предотвращени вытекани состава необходимо предусмотреть меры, например ограждение шва опалубкой.At the completion of the vulcanization processes of the base layer, it is able to independently maintain the given shape in a wide range of temperatures (up to -flOO ° C). The vulcanization process at elevated air temperatures, for example, under conditions of Central Asia, lasts 10-15 days, and immediately after the application of this layer it has a heat resistance of 50 ° C, which causes the composition to leak out of the seam, especially the vertical one. Therefore, to prevent the composition from leaking out, it is necessary to take measures, for example, to fence the seam with formwork.
Цель изобретени - упрощение технологии герметизации при повышенных температурах воздуха.The purpose of the invention is to simplify sealing technology at elevated air temperatures.
Цель достигаетс тем, что на поверхность основного герметизирующего сло нанос т эпоксидную композицию.The goal is achieved by applying an epoxy composition to the surface of the main sealing layer.
На подготовленные поверхности стыкуемых железобетонных элементов нанос т грунтовочный слой, содержащий компоненты в соотношении, мас.%:On the prepared surfaces of the joined reinforced concrete elements, a primer layer is applied, containing the components in a ratio, wt.%:
