Prikaz problemaView the problem
Na tržišču ni najti pločevine namenjene za konstrukcijski sistem sovprežnih stropov, katera bi z armaturo in strnjenim betonom tvorila sovprežno konstrukcijo in bi hkrati.No sheet metal is found on the market intended for the structural system of composite ceilings, which would form a composite structure with reinforcement and solidified concrete and would simultaneously.
služila kot delovna platforma, služila kot opaž za beton, ki pri zmernih razponih ne potrebuje dodatnega podpiranja, služila kot natezna armatura, bila oblikovana tako, daje možno nanjo s spodnje strani enostavno pritrjevati lažja bremena, kot so na primer inštalacije in po potrebi spuščeni stropovi in daje oblikovana tako, da ima dekorativni videz.served as a working platform, used as a formwork for concrete that does not require additional support at moderate spans, served as a tensile reinforcement, designed so that lighter loads such as installation and lowered ceilings can be easily attached to it from the underside and it is designed to have a decorative appearance.
Za zagotavljanje zgoraj navedenega, je do sedaj bilo potrebno montirati več elementov, kar pomeni hkrati večji strošek, več potrebnega časa pri montaži, večjo porabo materiala.To ensure the above, so far, more elements have had to be assembled, which means at the same time more cost, more time required for installation, more material consumption.
Stanje tehnikeThe state of the art
Pregled literature nakazuje široko uporabo različnih vrst opažev za beton.The literature review indicates the widespread use of different types of concrete formwork.
Za opaže za beton se običajno uporabljajo:The following are commonly used for concrete formwork:
plošče (npr. iz lesa), ki jih je potrebno dodatno podpirati in se po določenem času snamejo (hkrati s podporami) nosilci in polnila (npr iz opeke in betona), ki jih je potrebno v času izdelave stropa dodatno podpreti tovarniško pred-izdelani betonski elementi, ki se izdelajo v tovarniških obratih in se dostavijo na gradbišče ....panels (eg of wood) which need to be further supported and after a certain time the supports and fillers (eg of brick and concrete) are removed (at the same time as supports), which need to be supported at the factory prefabricated during the ceiling production concrete elements that are manufactured at factory sites and delivered to a construction site ....
Za montažo stropov je v literaturi najti veliko vrst različnih profilov oziroma profilirane pločevine, ki pa hkrati ne zagotavlja, lastnosti delovne platforme, možnosti uporabe kot armature za beton in nimajo hkrati ustreznih lastnosti, da bi bile uporabne kot natezna armatura.For the installation of ceilings, many types of different profiles or profiled sheets are found in the literature, which at the same time does not provide the characteristics of the work platform, the possibility of being used as concrete reinforcement and not having the appropriate properties to be used as a tensile reinforcement.
Za razvod inštalacij (električnih, telekomunikacijskih, računalniških ...) je v literaturi prav tako najti različne vrste in oblike kanalov, vendar pa ni najti elementa, ki bi kot en izdelek združeval vse navedene funkcionalne lastnosti ob hkrati optimirani obliki za dobro nosilnost in majhni porabi materiala.There are also various types and shapes of ducts for the installation of electrical (telecommunication, computer ...) divisions, but no element can be found that combines all of the above functional features as one product with optimized design for good load capacity and small consumes material.
Opis nove rešitveDescription of the new solution
Predstavljen izum predstavlja novo izvedbo elementa visokoprofilirane pločevine za sovprežne stropove, oziroma je namenjena za konstrukcijski sistem sovprežnih stropov. Predstavljena visokoprofilirana pločevina skupaj z armaturo in strjenim betonom tvori sovprežno stropno ploščo in ima v fazi izgradnje sledeče značilnosti:The present invention represents a new embodiment of an element of high-profiled sheet metal for ceilings, or is intended for the structural system of composite ceilings. The high-profiled sheet metal presented together with the reinforcement and hardened concrete forms a composite ceiling slab and has the following characteristics during the construction phase:
služi kot delovna platforma služi kot opaž za beton, ki pri zmernih razponih ne potrebuje dodatnega podpiranja služi kot natezna armatura ima dekorativni videzserves as a working platform serves as a concrete formwork that does not require additional support at moderate spans serves as a tensile reinforcement with a decorative appearance
- je oblikovana tako, da je možno nanjo s spodnje strani enostavno pritrditi lažja bremena kot so npr. inštalacije in spuščeni stropovi- it is designed in such a way that it is easy to attach lighter loads to it from the underside, such as eg. installations and suspended ceilings
Visokoprofilirana pločevina je oblikovana tako, da ob čim manjših stroških izdelave in ob čim manjši porabi materiala zagotavlja čim večje nosilnosti in hkrati ohranja zgoraj navedene lastnosti.High-profiled sheet metal is designed to ensure maximum load-bearing capacity while minimizing material consumption while maintaining the above characteristics.
Predmet izuma je obravnavan z zahtevnimi numeričnimi simulacijami, rezultati katerih so potrjeni z eksperimentom. Na osnovi numeričnih in eksperimentalnih analiz je ugotovljeno, da predstavljena visokoprofilirana pločevina zagotavlja zahtevane nosilnosti brez dodatnega podpiranja v fazi montaže in betoniranja:The subject of the invention is addressed by complex numerical simulations, the results of which are confirmed by experiment. Based on the numerical and experimental analyzes, it is concluded that the high-profile sheet metal presented provides the required load-bearing capacity without additional support during the assembly and concreting phase:
pri razponu 3,5 m pri višini profilov vsaj 74 mm inat a span of 3,5 m with a profile height of at least 74 mm and
- pri razponu 5,0 m pri višini profilov vsaj 110 mm (seveda obojno pri optimirani profilaciji in lastnostih pločevine)- at a range of 5.0 m with a profile height of at least 110 mm (of course both with optimized profiling and sheet metal properties)
Oblika profilacije pločevin je prilagojena predvsem montažnem stanju, kjer je potrebno zagotoviti nosilnost pri kar največjem razponu. Glavna parametra visokoprofilirane pločevine sta tako višina prečnega prereza, kakor debelina pločevine. Za nosilnost v sovprežnem stanju je poleg debeline betonske plošče pomembna tudi odpornost na vzdolžni strig, ki je poleg adhezijske vezi med betonom in pločevino odvisna tudi od oblike vtiskov na stojinah pločevine, ki s svojo obliko prispevajo k večji odpornosti. Pri optimiranju oziroma končnem oblikovanju visokoprofilirane pločevine so predvsem izstopali naslednji parametri:The shape of the profile of the sheets is especially adapted to the mounting condition, where it is necessary to ensure load capacity at the widest possible range. The main parameters of the high-profile sheet metal are both the height of the cross-section and the thickness of the sheet. In addition to the thickness of the concrete slab, the resistance to longitudinal shear is also important for the load-bearing capacity of the concrete slab, which, in addition to the adhesive bond between the concrete and the sheet, also depends on the shape of the impressions on the sheet pillars, which by their shape contribute to greater resistance. In optimizing or finishing the design of the high-profile sheet metal, the following parameters stood out in particular:
- omejitev višine: za zagotavljanje zadovoljivih mehanskih lastnosti se je izkazalo, da je minimalna višina profilov 74 mm pri razponu 3,5 m (brez vmesnih podpor), oziroma 110 mm pri razponu 5,o m (brez vmesnih podpor).- height restriction: in order to ensure satisfactory mechanical properties, the minimum profile height has been shown to be 74 mm at a range of 3.5 m (without intermediate supports), or 110 mm at a range of 5, o m (without intermediate supports).
- razmerje širine zgornje proti spodnji pasnici: pri ožji spodnji pasnici je poraba betona manjša, vendar se lahko nosilnost zaradi nesimetričnosti prereza zmanjša, pa tudi požarna odpornost je manjša, težje je tudi vgrajevanje čepov.- ratio of the width of the upper to the lower lane: in the narrower lower lane, the consumption of concrete is lower, but the load bearing capacity can be reduced due to the asymmetry of the cross-section, as well as the fire resistance is lower, and the use of plugs is more difficult.
- zagotavljanje odpornosti na vzdolžni strig med pločevino in betonom: pri odprtih profilih je ta manjša kot pri zaprtih. Pri tipičnih zaprtih profilih je spodnja pasnica zelo široka, kar zagotavlja veliko požarno odpornost, vendar tudi večjo težo plošče, kar se pozna pri lastnostih v montažnem stanju. Prikazana izvedbena primera (visokoprofilirani pločevini z višino profilov 74 in 110 milimetrov) sta zasnovana tako, da optimalno združujeta pozitivne lastnosti odprtih in zaprtih oblik.- Provision of resistance to longitudinal shear between sheet and concrete: for open profiles this is lower than for closed profiles. With typical closed profiles, the lower lane is very wide, providing high fire resistance, but also greater panel weight, as is known in the assembly state. The embodiments shown (high profiled sheets with profile heights 74 and 110 mm) are designed to optimally combine the positive properties of open and closed shapes.
- optimirani e oblike za zagotavljanje enostavnega pritrjevanja lažjih bremen na so vprežni strop: za montažo inštalacij, spuščenih stropov oz. drugih bremen, ki ne presegajo predpisane točkovne obremenitve (na primer 1 kN) sta pločevini oblikovani tako, da je mogoče enostavno pritrjevanje z zatikanjem oz. enostavnimi sistemi pritrjevanja.- optimized e forms to ensure easy attachment of lighter loads to the carriage ceiling: for installation of installations, suspended ceilings or. other loads not exceeding the prescribed point load (for example, 1 kN), the sheets are designed in such a way that they can be easily fastened by pinching or. simple attachment systems.
- optimiranie naklona stojine za zagotavljani e mehanskih lastnosti: kot ustrezen se je pri različnih dimenzijah in profilacijah visokoprofilirane pločevine (kakor tudi pri obeh predstavljenih izvedbenih primerih) izkazal 70(+-5)° naklon stojine. Z večjim naklonom stojine se doseže večja odpornost profila na vnos koncentrirane sile (reakcije nad podporami) v montažnem stanju.- optimization of the slope for the mechanical properties to be guaranteed: 70 (+ - 5) ° of the slope proved to be appropriate for the various dimensions and profiles of the high-profile sheet metal (as well as for the two examples presented). The greater the slope of the stand, the higher the resistance of the profile to the intake of concentrated force (reaction over supports) in the mounting state.
optimiranie ojačitve v pasnicah: z optimiranjem ojačitev se povečuje togost in lokalna stabilnost pločevine. Ojačitve so izvedene tako, daje z obliko napravljen kompromis med nosilnostjo profilacije in porabo materiala. Prav tako so ojačitve optimirane tako, da z večjimi ojačitvami ni mogoče doseči bistveno večje nosilnosti.optimization of reinforcement in the lanes: optimizing the reinforcement increases the stiffness and local stability of the sheet. The reinforcements are designed in such a way as to make a compromise between the load-bearing capacity of the profiling and the material consumption. Reinforcements are also optimized so that substantially higher payloads cannot be achieved with larger reinforcements.
Podrobneje je bistvo izuma pojasnjeno v nadaljevanju z opisom izvedbenih primerov in priloženih skic, pri čemer so skice del pričujoče patentne prijave in je na skicah prikazano:The essence of the invention is explained in more detail below with a description of the embodiments and the accompanying drawings, the drawings being part of the present patent application and the drawings show:
Skica 1 prikazuje visokoprofilirano pločevino 1, zgornjo pasnico 2, spodnjo pasnico 3, stojina 4, ojačitev pasnice 5, izboklina na stojini 6.Figure 1 shows the high-profile sheet 1, the upper belt 2, the lower belt 3, the web 4, the reinforcement of the web 5, the bulge on the web 6.
Skica 2 prikazuje visokoprofilirano pločevino 1, zgornjo pasnico 2, spodnjo pasnico 3, stojina 4, ojačitev pasnice 5, izboklina na stojini 6.Figure 2 shows the high-profile sheet 1, the upper belt 2, the lower belt 3, the web 4, the reinforcement of the web 5, the bulge on the web 6.
Skica 3 prikazuje visokoprofilirano pločevino.Figure 3 shows the high-profile sheet metal.
V prvem izvedbenem primeru prikazanem na sliki 1 je prikazan izvedbeni primer z nižjo nosilnostjo. Prikazana visokoprofilirana pločevina 1 zagotavlja zahtevane nosilnosti pri optimirani profilaciji in lastnostih pločevine brez dodatnega podpiranja v fazi montaže in betoniranja pri razponu 3,5 m pri višini profilov vsaj 74 mm. Pločevina ima povsem originalno obliko z izbočeno obliko profila v območju zgornje pasnice 2. Oblika omogoča boljšo povezavo med betonom in pločevino v vertikalni smeri in posledično tudi večjo odpornost na vzdolžni strig. Dobra stran take izbočene oblike je, da zmanjša prosto višino stojine 4 oz. da deluje kot ojačitev. Spodnja pasnica 3 in zgornja pasnica 4 imata v sredini polja trikotno ojačitev 5 (eno ali več), ki zmanjšuje vpliv lokalnega izbočenja. Spodnja pasnica je v izvedbenem primeru nekoliko ožja, s čimer se zmanjša lastna teža betona za montažno stanje. Pri izvedbi obešanja bremena na profilacijo je možno izdelati enostavno varianto z zatikanjem. V stojine so vtisnjene izbokline na stojini 6 K oblike, ki povečujejo odpornost pločevine na vzdolžni strig. V izvedbenem primeru je višina visokoprofilirane pločevine 74 mm, širina zgornje pasnice 118,85 mm, širina spodnje pasnice 100 mm. Trikotne ojačitve so izvedene v obliki pravokotnega trikotnika s pravim kotom na sredini ojačitve in globino oziroma višino 10 mm. Stojini s pasnicama zavzemata kot 70° (oziroma 110°). Vrhova izboklin na zgornji pasnici sta na višini 62 mm, njuna razdalja pa je 127,59 mm. Celotna širina posameznega profila znaša 255,95 mm. Notranji kot izboklin na zgornji pasnici zavzema 100 °. Višina izbokline gledano vzporedno s stojino je 8 mm, vse zaokrožitve na predmetu izuma pa so izvedene z radijem 3,6 mm. Bistvene lastnosti prikazane visokoprofilirane pločevine bistveno ne odstopajo pri ohranitvi dimenzij oziroma naklonskih kotov v področju +- 10°.The first embodiment shown in Figure 1 shows a lower carrying embodiment. High-profiled sheet 1 shown provides the required load-bearing capacity for optimized profiling and sheet-metal properties without additional support during the assembly and concreting phase at a range of 3.5 m at a profile height of at least 74 mm. The sheet metal has a completely original design with a convex shape profile in the area of the upper lane 2. The shape allows for a better connection between the concrete and the sheet in the vertical direction and consequently also greater resistance to the longitudinal shear. The good side of such a protruding shape is that it reduces the free height of the stand 4 oz. that it acts as a reinforcement. The lower lane 3 and the upper lane 4 have a triangular reinforcement 5 (one or more) in the middle of the field which reduces the effect of the local projection. The lower lane is slightly narrower in the embodiment, thus reducing the concrete's own weight for the assembly condition. When carrying out the loading of the load on the profile, it is possible to produce a simple variant with a pin. The projections are embossed with 6K-shaped projections that increase the resistance of the sheet to the longitudinal shear. In the embodiment, the height of the high-profile sheet is 74 mm, the width of the upper lane 118.85 mm, the width of the lower lane 100 mm. Triangular reinforcements are made in the form of a right-angled triangle with right angles in the middle of the reinforcement and a depth or height of 10 mm. The webs with belts stand at 70 ° (or 110 °). The tips of the projections on the upper lane are at a height of 62 mm and their distance is 127.59 mm. The total width of each profile is 255.95 mm. The inner bulge on the upper lane is 100 °. The height of the bulge when viewed parallel to the web is 8 mm, and all roundings on the subject matter of the invention are made with a radius of 3.6 mm. The essential characteristics of the high-profiled sheet shown do not significantly deviate while maintaining the dimensions or inclination angles in the + - 10 ° range.
V drugem izvedbenem primeru prikazanem na sliki 2 je prikazan izvedbeni primer z višjo nosilnostjo. Prikazana visokoprofilirana pločevina 1 zagotavlja zahtevane nosilnosti pri optimirani profilaciji in lastnostih pločevine brez dodatnega podpiranja v fazi montaže in betoniranja pri razponu 5,0 m pri višini profilov vsaj 110 mm. Pločevina ima povsem originalno obliko z izbočeno obliko profila v območju zgornje pasnice 2. Oblika omogoča boljšo povezavo med betonom in pločevino v vertikalni smeri in posledično tudi večjo odpornost na vzdolžni strig. Dobra stran take izbočene oblike je, da zmanjša prosto višino stojine 4 oz. da deluje kot ojačitev. Spodnja pasnica 3 in zgornja pasnica 4 imata eno ali več trikotnih ojačitev 5, ki zmanjšujejo vpliv lokalnega izbočenja. Spodnja pasnica je v izvedbenem primeru nekoliko ožja, s čimer se zmanjša lastna teža betona za montažno stanje. Pri izvedbi obešanja bremena na profilacijo je možno izdelati enostavno varianto z zatikanjem. V stojine so vtisnjene izbokline na stojini 6 K oblike, ki povečujejo odpornost pločevine na vzdolžni strig. V izvedbenem primeru je višina visokoprofilirane pločevine 110 mm, širina zgornje pasnice 135 mm, širina spodnje pasnice 100 mm. Trikotne ojačitve so izvedene v obliki pravokotnega trikotnika s pravim kotom na sredini ojačitve in globino oziroma višino mm. Stojini s pasnicama zavzemata kot 70° (oziroma 110°). Vrhova izboklin na zgornji pasnici sta na višini 84,06 mm, njuna razdalja pa je 153,28 mm. Celotna širina posameznega profila znaša 294,11 mm. Notranji kot izboklin na zgornji pasnici zavzema 100°. Višina izbokline gledano vzporedno s stojino je 10 mm, vse zaokrožitve na predmetu izuma pa so izvedene z radijem 3,6 mm. Bistvene lastnosti prikazane visokoprofilirane pločevine bistveno ne odstopajo pri ohranitvi dimenzij oziroma naklonskih kotov v področju +- 10°.In the second embodiment shown in Figure 2 an embodiment with a higher load capacity is shown. High-profiled sheet 1 shown provides the required load-bearing capacities with optimized profiling and sheet properties without additional support during the assembly and concreting phase at a range of 5.0 m with a profile height of at least 110 mm. The sheet metal has a completely original design with a convex shape profile in the area of the upper lane 2. The shape allows for a better connection between the concrete and the sheet in the vertical direction and consequently also greater resistance to the longitudinal shear. The good side of such a protruding shape is that it reduces the free height of the stand 4 oz. that it acts as a reinforcement. The lower lane 3 and the upper lane 4 have one or more triangular reinforcements 5 that reduce the impact of the local projection. The lower lane is slightly narrower in the embodiment, thus reducing the concrete's own weight for the assembly condition. When carrying out the loading of the load on the profile, it is possible to produce a simple variant with a pin. The projections are embossed with 6K-shaped projections that increase the resistance of the sheet to the longitudinal shear. In the embodiment, the height of the high-profile sheet metal is 110 mm, the width of the upper lane is 135 mm, the width of the lower lane is 100 mm. Triangular reinforcements are made in the form of a right-angled triangle with right angles in the middle of the reinforcement and depth or height mm. The webs with belts stand at 70 ° (or 110 °). The tops of the projections on the upper lane are 84.06 mm high and 153.28 mm apart. The total width of each profile is 294.11 mm. The inner bulge on the upper lane is 100 °. The height of the bulge when viewed parallel to the web is 10 mm, and all roundings on the subject matter of the invention are made with a radius of 3.6 mm. The essential characteristics of the high-profiled sheet shown do not significantly deviate while maintaining the dimensions or inclination angles in the + - 10 ° range.
Na sliki 3 je prikazana visokoprofilirana pločevina opisana v drugem izvedbenem primeru.Figure 3 shows the high-profile sheet metal described in another embodiment.
Razumljivo je, daje mogoče opisano rešitev izvesti tudi v drugačni oblikovni izvedenki, ki ne spreminja bistva izuma.It is to be understood that the described solution can also be implemented in a different design that does not alter the essence of the invention.
