Изобретение относитс к горной нромышленности , в частности дл использовани в горных выработках в рамной железобетонной, металлической и податливых креп х.The invention relates to the mining industry, in particular for use in mine workings in frame reinforced concrete, metal and flexible supports.
Известны шахтные зат жки, выполненные в виде плиты.Known mine tightening, made in the form of a plate.
Предложенна зат жка отличаетс от известной тем, что одна из сторон выполнена с отогнутой продольной гранью. Это обеспечивает смещение зат жки относительно рам крепи и одной относительно другой при осадке Кровли.The proposed tightening differs from that known in that one of the sides is made with a bent longitudinal face. This ensures that the fixture is displaced relative to the support frames and one relative to the other during the draft of the Roof.
На фиг. 1 Изображена предложенна зат жка; на ф,иг. 2 - .податлива крепь с зат жкой,FIG. 1 Depicts the proposed tightening; on f, ig. 2 - compliant fastener with tightening,
Зат жка 1 представл ет собой плоский элемент продольна грань 2 - отогнута; зат жка может быть изготовлена из стеклопластика, асбестоцемента и других материалов.Gag 1 is a flat element; the longitudinal face 2 is bent; the puff can be made of fiberglass, asbestos cement and other materials.
Устанавливаютс зат жки по длине внахлестку , при этом они могут смещатьс одна относительно другой.Overlapping puffs are installed overlap in length, and they can be displaced one relative to another.
Зат жка работает следующим образом.Zatka works as follows.
Во врем горного давлени на крепь при достижении максимальных нагрузок происходит смещение элементов рамы в узлах 3. При этом размер рамы по периметру уменьшаетс , в результате чего расположенные по периметру рамы зат жки занимают новое положение, смеща сь одна за другую.During rock pressure on the lining, when the maximum loads are reached, the frame elements in the nodes 3 are displaced. At the same time, the frame size around the perimeter decreases, with the result that the puffs located along the perimeter occupy a new position, shifting one after the other.
Предмет изобретени Subject invention
Шахтна зат жка дл горных выработок, выполненна в виде плиты, отличающа с тем, что, с целью обеспечени возможности ее смещени относительно рам крепи и одной относительно другой при осадке кровли, одна сторона зат жки выполнена с отогнутой продольной гранью.The mine tightening for mine workings, is made in the form of a plate, characterized in that, in order to allow it to be displaced relative to the support frames and one relative to the other during the roof draft, one side of the assembly is made with a bent longitudinal face.
