Description

Cieglo to laczy sie nastepnie do beda¬ cych .na wyposazeniu kolejki lubków mocujacych jezdna szyne.Montaz kolejki w wyrobisku nachylonym w obu¬ dowie stalowej odbywa sie lacznie ze wzmocnie¬ niem obudowy wyrobiska. W tym celu, jak przed¬ stawiono na rysunku, do koncówki kotwy pomie¬ dzy zawiesiem z uchem a stropem zaklada sie strzemie (5) mocujace i usztywniajace obudowe wy¬ robiska. Strzemie w przeciwnym do swojego otworu koncu ma wyprofilowane zagiecie (6), którym obej¬ muje stropnice obudowy usztywniajac ja i zabez¬ pieczajac przed dzialaniem sil osiowych i skosnych starajacych sie przesunac odrzwia obudowy. Po przeciwnej stronie otworu, strzemie (5) ma ele¬ ment usztywniajacy powodujacy utrzymanie kon¬ strukcji w polozeniu równoleglym do stropu. Ele¬ ment zawieszenia kolejki, rur, przenosników czy kabli, w postaci rozprezonej kotwy (1), w górnej swojej czesci posiada znana w swej istocie glowice (7) rozprezona w górotworze i stanowiaca czesc nosna zawieszenia. W dolnej czesci kotew (1) ma gwint, na który zaklada sie strzemie jak równiez zawiesie dociskane do stropu nakretka. Koncówka kotwy (1) wystajaca z otworu ma wykonany kwa¬ drat za pomoca którego rozpreza sie kotew w gó- 5 rotworze.Sposób wedlug wynalazku umozliwia pewne i szybkie zamocowanie urzadzen transportowych, rur posadzkowych, lutni wentylacyjnych czy prze¬ nosników tasmowych a nawet kabli. Jest to malo 10 pracochlonny proces wykonania robót, które do chwili obecnej wymagaly znacznych wysilków i dlu¬ giego czasu wykonania. 15 PL PLThis warmth is then connected to the louvers, which are equipped with the railway, which fasten the running rails. The assembly of the railway in the pit inclined in the steel casing is performed together with the reinforcement of the pit lining. For this purpose, as shown in the drawing, stirrups (5) are attached to the end of the anchor between the lifting eye and the roof, to fix and stiffen the workings. The stirrups at the end opposite to their opening have a profiled bend (6), which covers the canopy of the housing, stiffening it and preventing the action of axial and oblique forces trying to move the housing doorway. On the opposite side of the opening, the stirrup (5) has a stiffening element to keep the structure parallel to the ceiling. The suspension element of the railway, pipes, conveyors or cables, in the form of an expanded anchor (1), in its upper part has the head (7) known in its essence, stretched in the rock mass and constituting part of the suspension carrier. In the lower part of the anchors (1) there is a thread on which a stirrup is placed, as well as a sling pressed against the ceiling by a nut. The end of the anchor (1) protruding from the opening has a square with which the anchors expand in the top. The method according to the invention allows for secure and quick fastening of transport devices, floor pipes, ventilation ducts or belt conveyors and even cables. It is a little labor-intensive process of carrying out the works, which, until now, required considerable efforts and a long time of execution. 15 PL PL
