Abstract

Фрикционный болт (10) для сцепления посредством трения с внутренней поверхностью канала, высверленного в поверхности породы, содержащий удлиненную, преимущественно цилиндрическую трубу (11), которая выполнена с возможностью радиального расширения. Труба содержит передний конец (12) и задний конец (13) . Расширительное устройство (14) расположено внутри трубы для приложения нагрузки, стремящейся радиально расширить по меньшей мере один участок трубы. Удлиненный натяжной элемент (19) расположен продольно внутри трубы и соединен в или около одного конца натяжного элемента с расширительным устройством и соединен в или около противоположного конца натяжного элемента с анкерным устройством (13). Натяжной элемент выполнен с возможностью расширять расширительное устройство и оставаться соединенным между расширительным устройством и анкерным устройством, пока расширительное устройство расширено. Расширительное устройство содержит пару расширительных элементов (15, 16), первый из которых закреплен относительно трубы, а второй прикреплен к удлиненному натяжному элементу, причем приведение в движение натяжного элемента вызывает относительное перемещение между первым и вторым расширительными элементами, чтобы вызывать расширение расширительного устройства.
