Description
(54) МЕТАЛЛИЧЕСКАЯ КРЕПЬ(54) METAL STRAP
Изобретение относитс к креплению горных выработок.The invention relates to the fastening of mine workings.
Известны конструкции металлических крепей и специрофил , включающие отдельные элементы соединени узлами податливости 1.Designs of metal supports and special profiles are known, including individual elements of the connection by nodes of compliance 1.
При таком исполнении в узлах податливости возникают изгибающие моменты и не обеспечиваетс посто нное сопротивление крепи.With this design, bending moments occur in the nodes of compliance, and the support is not permanently supported.
Известны конструкции металлических крепей из спецпрофил , включающие узлы податливости , выполненные из отдельных элементов, соединенных замками, и средство дл сн ти изгибающих моментов с замков 2.Structures of metal supports made of special profiles are known, including nodes of compliance made of separate elements connected by locks, and means for removing bending moments from locks 2.
В этой крепи несуща способность зависит от качества сварных соединений гибкой пластины с элементами крепи и с бащмаком. Больщое количество элементов в податливых узлах усложн ет конструкцию.In this lining, the bearing capacity depends on the quality of the welded joints of the flexible plate with lining elements and with the basemack. The large number of elements in the pliable assemblies complicates the design.
Целью изобретени вл етс повыщение надежности и упрощение конструкции.The aim of the invention is to increase reliability and simplify the design.
Это достигаетс тем, что средство дл сн ти изгибающего момента образовано посредством клиновидного паза, который выполнен в наружном элементе узла податливости.This is achieved in that the means for removing the bending moment is formed by means of a wedge-shaped groove which is made in the outer element of the compliance node.
, На фиг. 1 изображен узел податливости крепи; на фиг. 2 - разрез по А-А фиг. 1., FIG. Figure 1 shows the support knot; in fig. 2 is a section along A-A of FIG. one.
Металлическа крепь из спецпрофил из элементов и узлов податливости. Узел податливости выполнен из отдельных элементов 1 и 2, установленных внахлестку и соедин емых замками 3, у наружного элемента 1 имеютс фиксаторы 4. Наружный элемент снабжен средством дл сн ти изгибающего момента в виде клиновидного паза 5, расположенного ниже фланцев спецпрофил 6 перпендикул рно к продольной оси наружного элемента.Metal lining of special profile of the elements and nodes of compliance. The compliance unit is made of separate elements 1 and 2, overlapped and connected by locks 3, the outer element 1 has locks 4. The outer element is equipped with means for removing the bending moment in the form of a wedge-shaped groove 5 located below the flanges of the special profile 6 perpendicular to the longitudinal axis of the outer element.
Сопр жение граней клиновидного паза 5 выполнено плавным без острых углов. Глубина клиновидного паза 5 обычно меньще рассто ни от днища спецпрофил до его фланцев 6, это обеспечивает необходимый запас прочности в опасном сечении. Благодар фиксаторам 4 замки 3 смещаютс вместе с наружным элементом 1 без перекосов.The junction of the faces of the wedge-shaped groove 5 is smooth without sharp corners. The depth of the wedge-shaped groove 5 is usually less than the distance from the bottom of the special profile to its flanges 6, this provides the necessary margin of safety in a dangerous section. Due to the clips 4, the locks 3 are displaced together with the outer element 1 without distortions.
