Tehnička zadaća Technical task

Predmet izuma je suhomontažna armirano betonska roštiljna ploča sa dvodijelnim blokom kao nosivom ispunom. Postavljanje ploče predviđeno je ručno bez ili s minimalnim podupiranjem i bez ikakve oplate. Glavni nosivi sustav ploče je čelično - betonski roštilj u koji se umeću dvodijelni predgotovljeni armirano betonski blokovi. Monolitizacijom se popunjavaju glavna i poprečna rebra te spojevi među blokovima. Donja ploha donjeg bloka s donjom plohom gredica i ležajnica formira strop pripravan za žbukanje. Gornja ploha gornjeg bloka zajedno s gornjim dijelom rebara i spojnica među blokovima formira završnu plohu AB ploče. The subject of the invention is a drywall reinforced concrete grill plate with a two-part block as a load-bearing filling. Placing the panel is planned manually without or with minimal support and without any formwork. The main supporting system of the slab is a steel-concrete grill into which two-part prefabricated reinforced concrete blocks are inserted. Main and transverse ribs and joints between blocks are filled with monolithization. The lower surface of the lower block together with the lower surface of the beds and beds forms a ceiling ready for plastering. The upper surface of the upper block together with the upper part of the ribs and the joints between the blocks forms the final surface of the AB plate.

Stanje tehnike State of the art

Premda se danas u svijetu u rabi veliki broj različitih ručno montažnih stropova, predloženi sustav originalna je novost jer je koncipiran kao roštiljni s dvodijelnim armirano betonskim blokom kao ispunom a k tome je još i potpuno ili u visokom stupnju samonosiv u svim fazama građenja. Najbliži po koncepciji rješenja su: sitnorebrasti PALK strop iz HP-P960170A, lakobetonski strop Ytong Portugal, FERT opekarski montažni strop, lakobetonski zidani strop iz HP- P970336A. Although a large number of different hand-assembled ceilings are used in the world today, the proposed system is an original innovation because it is designed as a grill with a two-part reinforced concrete block as filling, and it is also completely or to a high degree self-supporting in all phases of construction. The closest solutions in terms of concept are: fine-ribbed PALK ceiling from HP-P960170A, lightweight concrete ceiling Ytong Portugal, FERT brick prefabricated ceiling, lightweight concrete masonry ceiling from HP-P970336A.

Bit izuma The essence of invention

Bit izuma je u kombiniranoj primjeni predgotovljenih dvodijelnih armirano betonskih blokova kao ispune i nosivog elementa i predgotovljenih potpuno armiranih betonskih gredica. S time je postignut samonosivi nosivi kostur koji je ujedno oplata za daljnji rad na monolitizaciji konstrukcije. Ležajnice kao predgotovljeni elementi zajedno s blokovima formiraju oplatu za poprečna rebra. Monolitizacijom se dobiva roštiljni sustav s tlačnom pločom na gornjem kraju. The essence of the invention is in the combined application of prefabricated two-part reinforced concrete blocks as filling and load-bearing element and prefabricated fully reinforced concrete slabs. With this, a self-supporting load-bearing skeleton was achieved, which is also a formwork for further work on monolithic construction. The beds as prefabricated elements together with the blocks form the formwork for the transverse ribs. Monolithization results in a grill system with a pressure plate on the upper end.

Način industrijske primjene Method of industrial application

Način industrijske primjene izuma u najširem smislu je očigledan. Nova suhomontažna armirano betonska ploča po dijelovima može se proizvoditi u mini pogonima. Prilagodljiva je za novi način građenja raznovrsnih stropnih krovnih i sličnih konstrukcija. Podupiranje do raspona od 3.0 m nije potrebno a preko toga raspona do raspona od 7.5 m samo na jednom mjestu. Gredice imaju nadvišenje tako da se nakon izvedbe i opterećivanja konstrukcija progiblje u približno horizontalan položaj. The way of industrial application of the invention in the broadest sense is obvious. The new dry-cast reinforced concrete slab can be produced in parts in mini-plants. It is adaptable to a new way of building various ceiling, roof and similar structures. Supporting up to a span of 3.0 m is not necessary, and over that span up to a span of 7.5 m only in one place. The beams have an overhang so that after construction and loading, the structure sags to an approximately horizontal position.
