Abstract

Podne ploče dijele se u više skupina ovisno o materijalima od kojih se izvode ili načinu izvedbe. Podne ploče većinom se izvode od betona pogotovo armiranog betona kojeg karakteriziraju bolja trajnost i izdržljivost na određena opterećenja. Prvo se definira armaturni koš sastavljen od čeličnih šipki i mreža koji se formiraju u već postavljenom kalupu. Nakon postavljanja armature u kalup slijedi ugradnja betona i konačna obrada. Podjela armiranobetonskih podnih ploča ponajviše se odnosi na podjelu izvedbe dilatacijskih spojeva. Postoje različiti načini izvedbe ovisno o kojem materijalu je riječ ili položaju postavljanja dilatacijskih spojeva. Kod dilatacijskih spojeva pojavljuju se i mnogi problemi koji štetno djeluju na same ploče, radi toga je razvijena specifična izvedba armiranobetonskih podnih ploča, a to su ploče bez dilatacije. Njihova izvedba se temelji na adekvatnoj pripremi podloge, definiranju plastične mreže koja se sastoji od plastičnih cijevi i četverosmjernih spojnica, nakon toga se postavlja armaturna mreža te ugrađuje beton. Plastičnom mrežom dimenzija 1x1 m ostvaruju se mikropukotine u samom betonu te se time betonska ploča dijeli na kvadrate kojima se ostvaruje jednostavniji prijenos opterećenja. Karakteristike INB 06 sustava je da je utrošak manji, ugradnja brža te je sustav funkcionalniji u odnosu na klasičnu izvedbu podnih ploča.

Abstract (english)

Floor slabs are divided into several groups depending on the materials from which they are made or the method of execution. Floor slabs are mostly made of concrete, especially reinforced concrete, which is characterized by better durability and resistance to certain loads. First, the reinforcing cage is defined, composed of steel rods and meshes, which are formed in an already placed mold. After placing the reinforcement in the mold, concrete installation and final processing follow. The division of reinforced concrete floor slabs mainly refers to the division of the performance of expansion joints. There are different methods of execution depending on the material in question or the position of installation of the expansion joints. With expansion joints, there are many problems that have a detrimental effect on the panels themselves, for this reason, a specific version of reinforced concrete floor panels has been developed, which are panels without expansion. Their performance is based on the adequate preparation of the substrate, the definition of the plastic network consisting of plastic pipes and four-way connectors, after which the reinforcement network is installed and concrete is installed. With a plastic net measuring 1x1 m, microcracks are created in the concrete itself, and thus the concrete slab is divided into squares, which enable easier load transfer. The characteristics of the INB 06 system are that the consumption is lower, the installation is faster and the system is more functional compared to the classic design of floor slabs.
