Description
(54) МЕЖГОРИЗОНТНОЕ ЖЕЛЕЗОБЕТОННОЕ ПЕРЕКРЫТИЕ ПРИ ОТРАБОТКЕ ЩИТОВОЙ СИСТЕМОЙ КРУТЫХ ПЛАСТОВ(54) INTERGORIZONT REINFORCED CONCRETE OVERLAYING AT DEVELOPMENT OF SHIELD SYSTEM OF RACK
II
Изобретение относитс к средствам поддерживани межгоризонтных целиков угл при отработке щитовой системой крутых пластов, а именно к межгоризонтным железобетонным перекрыти м.The invention relates to the support of long-distance coal pillars during the development of steep seams by the shield system, namely to inter-horizontal reinforced concrete floors.
Известно межгоризонтное перекрытие из .сборного железобетона, включающее балки и стойки, образующие треугольные рамы, при этом балки выполнены Г-образной формы и укреплены на опорных плитах 1|.The inter-horizontal overlap of prefabricated reinforced concrete is known, which includes beams and pillars forming triangular frames, while the beams are L-shaped and fixed on the support plates 1 |.
Недостатками такого перекрыти вл ютс громоздкость конструкции и невозможность использовани при переменной мощности пласта.The disadvantages of such an overlap are the cumbersome structure and the impossibility of using it at a variable reservoir thickness.
Наиболее близким по технической сущности и достигаемому результату вл етс межгоризонтное железобетонное перекрытие при отработке щитовой системой крутых пластов, включающее замоноличенный бетоном арматурный каркас и анкеры, установленные в боковых породах в несколько р дов 2.The closest in technical essence and the achieved result is the mezhgorontny reinforced concrete overlap during the development of steep seams by the shield system, including reinforced framework reinforced with concrete and anchors installed in lateral rocks in several rows 2.
Недостаток известного перекрыти здключаетс в том, что дл его креплени к боковым породам необходимо разделывать специальные ннщи, что увеличивает трудоемкость работ. Кроме того, при измен ющейс мощности пласта усложн етс и повышаетс трудоемкость монтажа арматурного каркаса .A disadvantage of the known overlap is that in order to attach it to side rocks, it is necessary to cut up special tools, which increases the complexity of work. In addition, with varying thickness of the formation, the complexity of mounting the reinforcement cage increases.
Цель изобретени - снижение трудоемкости работ при возведении перекрыти .The purpose of the invention is to reduce the complexity of the work during the construction of the ceiling.
Эта цель достигаетс тем, что перекрытие по высоте снабжено металлическими по са- . мн, которые горизонтально прианкерованы к боковым породам, а арматурный каркас выполнен из стальных канатов, которые приJ peплeны к по сам.This goal is achieved by the fact that the overlap in height is provided with metal over the a-a. PL, which are horizontally anchored to the side rocks, and the reinforcement cage is made of steel ropes, which are attached to themselves.

На чертеже изображено межгоризонтное железобетонное перекрытие.The drawing shows inter-horizontal reinforced concrete floor.
Межгоризонтное железобетонное перекрытие состоит нз металлических по сов I, прикрепленных анкерами 2 к кровле и почвеThe inter-horizontal reinforced concrete slab consists of metal cores I, attached by anchors 2 to the roof and the ground
15 пласта, стальных канатов 3 в качестве арматуры и бетонного заполнени 4. Металлические по са имеют поперечное сечение в форме угольников, в боковых полках которых предусмотрены отверсти дл пропуска канатов 3. Дл лучшего воспри ти раст гивающих,15 layers, steel ropes 3 as reinforcement and concrete filling 4. The metal panels have a cross section in the form of squares, in the side shelves of which there are holes for the passage of the ropes 3. In order to get a better view of stretchers,
20 изгибающих и касательных напр жений KaV наты 3 расположены по нормали, падению ттласта и под углом, образу пространственную рещетку.The 20 bending and tangential stresses of KaV Nata 3 are located along the normal, the fall of the ttlast and at an angle, forming a spatial grid.
