Abstract

Kaszt górniczy, stosowany w podziemnych zakladach górniczych do podparcia stropu, sklada sie belek (1, 2, 3, 4, 5), ulozonych w warstwach jedna na drugiej, poprzecznie usytuowanych. Krzyzujace sie belki kolejnych warstw w miejscu styku posiadaja wreby (6) o dlugosci co najmniej równej szerokosci belek, pozwalajace na wzajemne przenikanie belek na glebokosc dostateczna dla uzyskania styku dolnych i górnych powierzchni najblizszych sobie równoleglych belek kasztu. Ulozone jedna na drugiej belki tworza sciany (I, II III, IV, V), polaczone ze soba w wyniku wzajemnego przenikania belek kolejnych warstw i skrzyzowane pod dowolnym katem. W swojej konstrukcji kaszt zawiera belki (7), uksztaltowane z polaczonych ze soba trwale elementów.The mining castle, used in underground mining plants to support the roof, consists of beams (1, 2, 3, 4, 5), arranged in layers on top of each other, transversely located. The intersecting beams of successive layers at the point of contact have notches (6) with a length at least equal to the width of the beams, allowing mutual penetration of the beams to a depth sufficient to obtain the contact of the lower and upper surfaces of the nearest parallel beams. Placed on top of each other beams form walls (I, II III, IV, V), connected to each other as a result of mutual penetration of beams of successive layers and crossed at any angle. In its construction, the castle contains beams (7), formed of permanently connected elements.
