Изобретение относится к горной промышленности, к анкерной крепи горных выработок. Распорный анкер включает стержень с распорной втулкой из эластичного материала, надетой на трубку скольжения, концентрично охватывающей стержень, имеющий головку на одном конце и резьбу на другом конце, на котором навинчена муфта, соединенная резьбой со штангой. Головка выполнена в виде закрепленной шайбы, имеющей вырез на контакте со стержнем, в который вставлен клин, размещенный между эластичной втулкой и стержнем, на который надета на интервале между эластичной втулкой и муфтой проставка высотой, равной величине навинчивания стержня в муфту, причем трубка скольжения выполнена в виде антифрикционного покрытия, например, в виде слоя мыла.The invention relates to the mining industry, to the anchor lining of mine workings. The expansion anchor includes a rod with a spacer sleeve made of an elastic material, worn on a slip tube, concentrically covering the rod, having a head at one end and a thread at the other end, at which the coupling is screwed, connected by a thread with a rod. The head is made in the form of a fixed washer having a notch on the contact with the rod into which a wedge is inserted, placed between the elastic sleeve and the rod, which is placed on the interval between the elastic sleeve and the coupling spacer with a height equal to the amount of screwing the rod into the coupling, and the sliding tube is made in the form of an anti-friction coating, for example, in the form of a layer of soap.
