(5) ТРАПЕЦИЕВИДНАЯ КРЕПЬ ГОРНЫХ ВЫРАБОТОК(5) KEYSTONE MEASURING STRIP

. .

Изобретение Относитс к подземной добычи полезных ископаемых и предназначено дл креплени горных, выработок.Известна трапециевидна крепь, ; пригодна дл креплени горных выработок значительной ширины и имеюща верхн к, усиленный шатровым элементом, подпирающим своими подкосами верхн к снизу 1.The invention relates to underground mining and is intended to mount mining workings. Known trapezoidal lining,; suitable for fastening mines of considerable width and having an upper to it, reinforced by a tent element, supporting by its struts upper to the bottom 1.

Однако эта крепь не обеспечивает надежное поддерживание выработки большого пролета, поскольку по своей конструкции она предусматривает соединение подкосов под серединой верхн ка.However, this lining does not provide reliable maintenance of the development of a large span, since by its construction it provides for the connection of the struts under the middle of the upper ka.

Известна трапециевидна крепь горных выработок, включающа стойки, верхн к и соединенный с ним усили- . вающий элемент, посредством узлов креплени , расположенный над верхн ком , ст жки, узлы податливости 2.A trapezoidal support of mine workings is known, comprising struts, upper and connected with it. A tangent element, by means of attachment points, located above the top, of the tie bar, flexibility nodes 2.

Однако известна крепь не предназначена дл креплени участков выработки большой ширины и не обладает большой несущей способностью.However, the known lining is not intended for fastening large-width production areas and does not have a large bearing capacity.

Цель изобретени - упрощение сборки крепи и повышение несущей способности .The purpose of the invention is to simplify the lining assembly and increase the carrying capacity.

Эта цель достигаетс тем, что , крепь снабжена подкосами и Z-обраэной стойкой, а усиливаюп й элемент выполнен 8 виде шатра, при этом Z-образна стойка установлена между This goal is achieved by the fact that, the lining is equipped with struts and a Z-shaped strut, and the reinforcement element is made 8 of a tent shape, with the Z-shaped strut mounted between

10 вершиной шатрового элемента и верхн ком , а подкосы выполнены из спаренных отрезков спецпрофил и закреплень одними концами на стойках, а доугими - на верхн ке в месте скре15 плени его с шатровым элементом.10 with the top of the tent element and the top panel, and the struts are made of paired special profile segments and fastened with the ends on the racks, and with the tips on the top in the place where it is covered with the tent element.

На фиг. 1 изображена крепь с детал ми; на фиг, 2 - разрез А-А на фиг. 1.FIG. 1 shows lining with details; FIG. 2 is a section A-A in FIG. one.

Крепь содержи т верхн к 1, узлы The support contains top to 1, knots

Claims

20 2 compliance, gusset 3, struts kf stand 5, reinforcing the top to 1 tent element 6, the top of which is fastened with a Z-shaped stand 7 39 with Ear 1, Schitter element with its curved ends of the inclined racks 6 embedded in the top to 1, B in turn, the upper to 1 at the same points is inserted into the ends of the struts C and all three parts are tightened by the straps 3. The support works as follows. The vertical load on the support is perceived largely by the reinforcing element b, transmitting it, by virtue of its hipped construction, from the middle of the top 1 at the midpoint of its half-span and through the under braids k brought down to these points, then to the pillars S To strengthen the tent element itself, there is a Z shaped vertical pillar 7, which can be used to accept both compressive stresses from the top of the tent element and growth Guivative loads when lowering the middle of the cusp 1. In the latter case, the bent ends of the Z-shaped stand must be attached to the ph1 and the tent element 6, for example, with straps (not shown), the tent element b, the vertical Z-shaped stand 7 can be connected This connection is preferable from the point of increase in the carrying capacity of the reinforced upper support. To prevent excessive slippage of the ends of the tent element b and the struts on the top 1i and the rack 5 | on the latter and the upper 4 ko, slippage limiters can be arranged, for example, in the form of weld tides, the invention will increase the effective maintenance of the roof of workings with a large cross section and provide the ability to perceive more significant rock pressure from the top. Formula of Invention Trapezoid lining of mine workings, comprising racks, upper and connected with it reinforcing element, by means of lashing fasteners located above the upper crown, strapping, compliance nodes, is different from the fact that, in order to simplify lining assembly and increase bearing capacity, the lining is equipped with struts and a 2-shaped stand, and the reinforcing element is designed as a tent, while the Z-shaped stand is installed between the top of the tent element and the top one, and the struts are made of paired special profile and zack sections Replenished by some ends on racks, and by others - on the top in place where it was fastened with a tent element. .
