Abstract
Изобретение относитс к горному делу и м.б. использовано при креплении капительных и подготовительных выработок, проводимых по породам средней и низкой прочности. Цель изобретени - повышение жесткости крепи и ее несущей способности. Металлоанкерна крепь состоит из верхн - ка 1 и стоек (С) 2, зат жек 3, хомутов 4, планок (П) 5 с отверсти ми 6, гаек и анкеров (А) 8. Последние установлены по периметру крепи и проход т через отверсти 6 тех П 5. с которыми не взаимодействуют хомуты 4. П 5, сквозь которые проход т А 8. в местах соединени верхн ка 1 со стойками 2 жестко присоединены к боковым полкам спецпрофил С 2. Верхн к 1 своими торцами взаимодействует с торцами П 5 в местах их соединени с С 2. 3 ил.The invention relates to mining and m. used for fastening of capital and preparatory workings carried out on rocks of medium and low strength. The purpose of the invention is to increase the rigidity of the support and its carrying capacity. Metal anchor lining consists of top 1 and racks (C) 2, tacks 3, clamps 4, strips (P) 5 with holes 6, nuts and anchors (A) 8. The latter are installed along the perimeter of the lining and pass through the holes 6 of those P 5. with which the collars do not interact. 4. The P 5 through which the A 8 pass. 8. At the junction points of the top 1 with the pillars 2, special profile C 2 is rigidly attached to the side shelves. in the places of their connection with С 2. 3 Il.
