Description

Jedna z najslabszych stron obecnego budownictwa sa legairy, t j. ukladane w nasypie beleczki z drzewa miekkiego lub twardego, do których przybija sie gwoz¬ dziami podloge.Grzyb domowy, próchnica i tym podob¬ ne szkodniki zwykle od legarów rozpoczy¬ naja swoje dzielo zniszczenia, igdyz tam znajduja podstawowe warunki swego roz¬ woju: brak swiatla, brak przewiewu — wilgoc.Stworzenie lepslzych warunków dla le¬ garów jest prawie niemozliwe: gdy urza¬ dzi sie przewiew, itraci sie na cieple po¬ mieszkania; zupelne, wkoncu, usuniecie wilgoci jest watpliwe — osobliwie przy po¬ dlogach, które musiza byc zmywane, gdyz woda dostaje sie podczas mycia* do nasypu i przy braku przewiewu tworzy wilgoc.Najpe"wniejszem wyjsciem z tego jest zwiekszenie trwalosci legarów przez wyko¬ nanie ich z materjalu odporniejszego od drzewa, który to materjal musi zarazem pozwalac na wbijanie gwozdzi podlogo¬ wych.Zagadnienie to rozwiazuje wynalazek niniejszy.Legar wykonuje sie jako belke betono¬ wa lub zelazobetonowa o specjalnej bu¬ dowie, widocznej i lafwo zrozumialej z przekrójów poprzecznych, przedstawio¬ nych na fig. 1, 2 i 3 rysunku. Belke zabe-tonowuje sie dwoma odmiennemi miesza- njnami^ a mianowicie: czesc dojifa b *belki wykonuje sie ze zwyklego betonu cementowo-zwirowego— czesc zas górna a betonuje sie mieszanina umozliwiajaca wbijanie gwozdzi (np. ce¬ ment z zuzlem lub trocinami, lub tez za¬ prawa cementowo-wapienna).Fig. 1, 2, 3 uwidoczniaja trzy odmienne sposoby wykonania legarów wedlug wyna¬ lazku: na fig. 1 wykonano czesc „a" na cala szerokosc belki, a na fig. 2 czesc „a" wy¬ stepuje jako Wkladka wbetonowana w czesc „6", przyczem ^wkladka ta moze byc wykonana nawet z drzewa, jak to uwidocz¬ niono na fig. 3. PLOne of the weakest points of the present-day building industry is the legaires, i.e. the soft or hardwood bars laid in the embankment, to which the floor is nailed with nails. They never find the basic conditions for their development there: no light, no air draft - moisture. It is almost impossible to create better conditions for the loggers: when there is a draft, it wastes to the warmth of the apartment; Complete removal of moisture is doubtful - especially with floors that need to be washed, because water gets into the embankment during washing * and creates moisture in the absence of air draft. The best way out of this is to increase the durability of the joists by finishing They are made of a material more resistant than wood, which at the same time must allow for driving floor nails. This problem is solved by the present invention. The brick is made as a concrete or iron-concrete beam with a special structure, visible and easily understandable from the cross-sections, 1, 2 and 3 of the drawings. The beam is concreted with two different mixers, namely: part of the dojifa b * of the beam is made of ordinary cement-gravel concrete - and the upper part is concreted with a mixture enabling driving nails (e.g. cement with slag or sawdust, or also cement-lime mortars) Fig. 1, 2, 3 show three different ways of making the joists according to the invention : in fig. 1 part "a" has been made to the entire width of the beam, and in fig. 2 part "a" appears as a concrete insert in part "6", because this insert can even be made of wood, as will be shown Is shown in Fig. 3.
