Description

(54) КРЕПЬ ПОДГОТОВИТЕЛЬНЫХ ВЫРАБОТОК(54) STRONGHOOD OF THE PREPARATORY WORKS

II

Изобретение относитс  к горному делу и может быть использовано при креплении горных вьфаботок рамной крепи с гибкой рулонной зат жкой.The invention relates to mining and can be used in the fastening of mountain mount frame lining with a flexible reel.

Известна крепь подготовительных выработок по авт. св. № 378626, включающа  рамы крепи и гибкую рулонную зат жку с соединительными узлами.Known lining preparatory workings of ed. St. No. 378626, which includes support frames and a flexible roll tightening with connecting nodes.

Целью изобретени   вл етс  надежное закрепление конпов и стыков полос гибкой рулонной зат жки.The aim of the invention is to securely fasten the sleeves and the seams of the flexible coil bands.

Это достигаетс  тем, что прижимной элемент выполнен упругим, а его поперечное сечение соответствует форме профил  шахтной крепи.This is achieved by the fact that the clamping element is made elastic, and its cross section corresponds to the shape of the shaft support profile.

На чертеже изображена предлагаема  крепь подготовительных выработок.The drawing shows the proposed lining preparatory workings.

Крепь состоит на рамы 1, упругого прижимного элемента 2, между которыми зажимаетс  полоса зат жки 3 с помощью болта 4 и гайки 5. Вначале производитс  закрепление стыков и конпов полос зат жки . Затем между концами полос зат жки ее закрепление и нат жение.The support consists of a frame 1, an elastic clamping element 2, between which the fastening band 3 is clamped with the help of a bolt 4 and a nut 5. First, the joints and the fastening of the fastening strips are fixed. Then, between the ends of the bands of tightening, its fastening and tension.
