Description
Wada znanych zelbetonowych stropów bel¬ kowych jest brak poprzecznego ankrowania, wskutek czego stropy te przeginaja sie pod obciazeniem. Wynalazek usuwa te wade przez zastosowanie poprzecznego ankrawania i konsoli.Istota wynalazku polega na zaoszczedze¬ niu w znacznej mierze materialów, w calosci zas drzewa. Po ulozeniu belek strop jest natychmiast w calej pelni uzywalny bez ja¬ kiegokolwiek oszalowania.Na rysunku fig. 1 przedstawia poprzecz¬ ny przekrój belki z uzbrojeniem. W górnej czesci belki znajduja sie strzemiona a, wy¬ stajace po obu obrzezach i tworzace po ulo¬ zeniu dalszych belek otwór 6, przez który przesuwa sie zelazo ankrowe c (fig. 3).Fig. 2 przedstawia izometrycznie gotowa belke z lozyskami f oraz konsolami e, któ¬ re w odstepach 1 m wykonywa sie przy wy¬ robie belek. Poza ankrowaniem konsole e stanowia dalsze zabezpieczenie przeciw wy¬ gieciu. Lozyska f belek sa pelne. Belka, uwidoczniona na fig. 1, jest wykonana z ce¬ mentu i zwiru oraz uzbrojona zelazem g wedlug obliczen statycznych, przy czym strzemiona a wbudowuje sie w odstepach 30 cm przez cala dlugosc belki, a konsole c, uzbrojone zelazem; w odstepach 1 m.Wreszcie fig. 3 przedstawia izometrycznie poprzeczny przekrój ulozonych • belek. Po ulozeniu belek i przesunieciu zelaza ankro- wego c przez otwory b zalewa sie powsta¬ jace wglebienie d betonem. •Belki wedlug wynalazku sluza do kon¬ strukcji stropów i dachów. W zastosowa- PLA disadvantage of the known reinforced concrete beam ceilings is the lack of transverse anchoring, as a result of which the ceilings bend under load. The invention overcomes these disadvantages by using transverse trimming and a console. The essence of the invention consists in saving largely materials, and entirely wood. After the joists have been installed, the floor is immediately fully usable without any formwork. In the drawing, Fig. 1 shows the cross-section of the reinforcement beam. In the upper part of the beam, there are stirrups a, protruding on both edges and creating an opening 6 after placing further beams, through which ankle iron c passes (Fig. 3). 2 shows isometrically a finished beam with bearings f and consoles e, which are made at 1 m intervals for the production of beams. In addition to locking, the consoles provide a further protection against bending. The bearings of the beams are full. The beam, shown in Fig. 1, is made of cement and gravel and reinforced with iron g according to static calculations, the stirrups a being built in 30 cm intervals through the entire length of the beam, and the consoles c, reinforced with iron; at intervals of 1 m. Finally, Fig. 3 shows an isometrically cross-section of the arranged beams. After arranging the beams and moving the ankle iron c through the holes b, the resulting cavity d is poured with concrete. • The beams according to the invention are used in the construction of ceilings and roofs.
