Description

i DK 167404 B1in DK 167404 B1

Den foreliggende opfindelse angår et system omfattende en sammensat bjælke og en sammensat plade til anvendelse i tage, lofter eller gulve i bygninger, som består af en sammensat bjælke, sammensatte plader og støbte komponenter, som bæres af den, og hvor den sammen-5 satte bjælke er dannet af en eller flere profil pi ader. Udtrykket sammensat plade indbefatter her også en betonplade støbt på forspændte hule plader.The present invention relates to a system comprising a composite beam and composite panel for use in roofs, ceilings or floors of buildings consisting of a composite beam, composite panels and molded components supported by it and wherein the composite beam is formed by one or more profile pi veins. The term composite slab here also includes a concrete slab molded on prestressed hollow slabs.

Sammensatte plader og bjælker og deres systemer kendes fra FI 10 patentansøgningerne nr. 862035, 863396 og fra US patentskrift nr.Composite panels and beams and their systems are known from FI 10 Patent Applications Nos. 862035, 863396 and from US Pat.

2.064.910. Endvidere er profil formsystemerne kendt fra EP patentpublikation nr. 240857 og fra FI patent nr. 63465 i almindelighed beliggende indenfor opfindelsens område. I FI patentansøgning nr.2064910. Furthermore, the profile molding systems are known from EP Patent Publication No. 240857 and from FI Patent No. 63465 generally located within the scope of the invention. In FI patent application no.

86035 er foreslået et system, hvor formen af den sammensatte bjælke 15 er sammensat af to tynde galvaniserede stål pi ader, der er forbundet med hinanden underneden. Støbning finder sted ovenpå enheden dannet af den sammensatte plade og den sammensatte bjælke og skaber således en monolitisk konstruktion. Den sammensatte bjælke skal her armeres separat, til trods for at forbindelsesstederne under den sammensatte 20 bjælke danner en vedhængende kant. Armering kræves i selve bjælken, i dens fastgørelse til den sammensatte plade og på bjælken som øvre overf1 adearmering.86035 is proposed a system in which the shape of the composite beam 15 is composed of two thin galvanized steel pads connected to each other below. Molding takes place on top of the unit formed by the composite plate and the composite beam, thus creating a monolithic construction. Here, the composite beam must be reinforced separately, despite the fact that the connection points below the composite beam form an adherent edge. Reinforcement is required in the beam itself, in its attachment to the composite plate and on the beam as upper surface reinforcement.

FI patentansøgning nr. 875327 viser et betonrammesystem, hvor 25 bjælkekomponenten, der er åben forneden, er støbt i forvejen, og sammensatte plader er understøttet på flangeelementer dannet i dens nederste sektion, og hvor enheden dannet af de sammensatte plader og rammebjælken er støbt ud i et, så at konstruktionen har god brandbeskyttelse. I konstruktionerne i henhold til fig. 8,9 og 10 er 30 hverken vedhængningen af det indre af bjælken og mellem den sammensatte bjælke og de sammensatte plader fuldstændig.FI Patent Application No. 875327 discloses a concrete frame system in which the beam component, which is open at the bottom, is molded in advance and composite plates are supported on flange elements formed in its lower section, and where the unit formed by the composite plates and the frame beam is cast out. one, so that the construction has good fire protection. In the structures of FIG. 8,9 and 10, neither the adhesion of the interior of the beam and between the composite beam and the composite panels is complete.

Formålet med den foreliggende opfindelse er at opnå en mere effektiv enhed dannet af en sammensat bjælke og sammensatte plader, hvor 35 konstruktionshøjden især kan være mindre end tidligere. Hovedtræk kene ved opfindelsen fremgår af patentkravene. I systemet ifølge opfindelsen binder stængerne eller boltene, som går gennem bjælken, bjælkekonstruktionen og pladerne så godt, at pladekomponenterne bærer trykkraften i retning af bjælken over en stor bredde. I dette DK 167404 B1 2 tilfælde stiger den neutrale akse betydeligt, når højden af træksiden vokser proportionalt. Opfindelsen kan også anvendes, når en boltekonstruktion anvendes i systemet til at holde de forskellige komponenter sammen. Hvis den tværgående armering er gjort tilstræk-5 kel i g lang, kan den også virke som øvre overfladearmering. Den bliver imidlertid mest fordelagtigt fremstillet separat.The object of the present invention is to obtain a more efficient unit formed by a composite beam and composite panels, the construction height in particular being smaller than before. The main features of the invention are set forth in the claims. In the system of the invention, the rods or bolts passing through the beam bind the beam structure and the plates so well that the plate components carry the compressive force in the direction of the beam over a wide width. In this case, the neutral axis increases significantly as the height of the traction side increases proportionally. The invention may also be used when a bolt structure is used in the system to hold the various components together. If the transverse reinforcement is made sufficient in g long, it can also act as upper surface reinforcement. However, it is most advantageously manufactured separately.

Opfindelsen skal herefter forklares nærmere under henvisning til tegningen, som viser forskellige udførelsesformer ifølge opfinde!-10 sen, idet fig. 1 viser systemet i forbindelse med en sammensat bjælke, der er åben på undersiden, fig. 2 den udførelsesform, der betragtes som den bedste, 15 fig. 3 et tværsnit i fig. 2 og fig. 4 systemet i forbindelse med hule plader.The invention will now be explained in more detail with reference to the drawing, which shows various embodiments of the invention, FIG. 1 shows the system in connection with a composite beam open on the underside; FIG. 2 shows the embodiment which is considered the best, FIG. 3 is a cross-sectional view of FIG. 2 and FIG. 4 system for hollow plates.

Det på tegningen viste system består af et sammensat bjælkeprofil 2 og sammensatte plader 1, som bæres på flangen 3 af bjælkeprofilet.The system shown in the drawing consists of a composite beam profile 2 and composite plates 1 which are supported on the flange 3 of the beam profile.

20 Det sammensatte bjælkeprofil 2 er forudstøbt og indbefatter en støbt komponent 11. På dette trin er tværgående stålstænger 8 også anbragt i det sammensatte bjælkeprofil 2. Disse forbliver inden i den støbte komponent 9 og virker som øvre overfladearmering af den kontinuerlige plade ved understøtningsstedet. De tværgående stålstænger 8 er 25 anbragt gennem huller 5, som er dannet tæt ved den øverste overflade 4 af den sammensatte bjælke 2. Den sammensatte bjælke har her forspændingselementer 6,7 og 10.The composite beam profile 2 is pre-cast and includes a molded component 11. At this stage, transverse steel bars 8 are also placed in the composite beam profile 2. These remain within the molded component 9 and act as upper surface reinforcement of the continuous plate at the support site. The transverse steel bars 8 are arranged through holes 5 formed close to the upper surface 4 of the composite beam 2. The composite beam here has biasing elements 6,7 and 10.

De tværgående stålstænger 8 har herved driftsfunktioner. Udover at 30 de virker som øvre overfladearmering for den kontinuerlige plade ved understøtningsstedet, forbinder de pladen med den sammensatte bjælke, og for det tredie virker de som adhæsion for den indvendige støbte masse 11 i den sammensatte bjælke til det sammensatte bjælkeprofil 2.The transverse steel bars 8 hereby have operating functions. In addition to acting as upper surface reinforcement for the continuous plate at the support site, they connect the plate to the composite beam, and thirdly, they act as adhesion for the inner molded mass 11 of the composite beam to the composite beam profile 2.

35 På grundlag af praktiske forsøg anvendes opfindelsen bedst i overensstemmelse med fig. 2. Den sammensatte bjælke er her profiler som et retvinklet hatteprofil, hvis nederste sektion indbefatter flangekomponenter, ovenpå hvilke det er muligt at anbringe de DK 167404 Bl 3 sammensatte pladeprofiler. En bjælke med en samlet højde på 280 mm er forsynet med gennemgående stålstænger, der er 420 mm lange og har en diameter på 16 mm. Bjælkeprofilet 12 er forudstøbt, og de tværgående stålsstænger binder betonen fast til profilet. Den færdige 5 sammensatte bjælke sættes på plads, og de sammensatte plader 1 anbringes ovenpå flangerne 15. Derefter finder udstøbning sted, som følge af hvilket den støbte komponent 9 danner en enhedsstruktur ovenpå de sammensatte plader 1 og den sammensatte bjælke. Det er mest fordelagtigt at anvende stålnet som overfladearmering 13. Denne 10 strækker sig til hver side af bjælken over ca. en fjerdedel af spændvidden, ca. 0,3 gange bredden af spændvidden af trykoverfladen kan overføres fra pladen til bjælken, når adhæsionen mellem bjælken og pladen er perfekt. Fig. 3 viser den principielle fordeling mellem tryk og træk i en rammekonstruktion i henhold til opfindelsen.35 On the basis of practical experiments, the invention is best used in accordance with FIG. 2. The composite beam is here profiles as a right-angled hat profile, the lower section of which includes flange components, on top of which it is possible to affix the DK 167404 Bl 3 composite plate profiles. A beam with a total height of 280 mm is provided with through steel bars 420 mm long and 16 mm in diameter. The beam profile 12 is pre-cast and the transverse steel bars tie the concrete to the profile. The finished 5 composite beam is put in place and the composite plates 1 are placed on top of the flanges 15. Then molding takes place as a result of which the molded component 9 forms a unit structure on top of the composite plates 1 and the composite beam. It is most advantageous to use steel mesh as a surface reinforcement 13. This 10 extends to each side of the beam over approx. one quarter of the span, approx. 0.3 times the width of the span of the pressure surface can be transferred from the plate to the beam when the adhesion between the beam and the plate is perfect. FIG. 3 shows the principle distribution between pressure and tension in a frame structure according to the invention.

15 Trykoverfladearealet strækker sig stærkt til pladesektionerne, i hvilket tilfælde selve den sammensatte bjælke på træksiden virker mere effektivt.The pressure surface area extends strongly to the plate sections, in which case the composite beam itself on the pull side acts more efficiently.

I et tilfælde kan de sammensatte pladeprofiler også erstattes af 20 hule plader 17, fig. 4. Disse er anbragt på en tilsvarende måde ovenpå flangen 15 på den sammensatte bjælke, men hulrummene ved deres ender er åbne over en afstand på 50-100 cm. Langsgående stænger 18 er skubbet ind fra denne åbning. Disse skal derpå bøjes nedad, hvilket ikke er en optimal løsning ud fra adhæsionssynspunk-25 tet, men det er et kompromis, som denne konstruktion kræver. Under støbning bliver enderne af hulrummene i de hule plader fyldt med beton, hvorefter de vil modstå langsgående sammentrykning.In one case, the composite plate profiles may also be replaced by 20 hollow plates 17; 4. These are similarly arranged on top of the flange 15 of the composite beam, but the voids at their ends are open over a distance of 50-100 cm. Longitudinal bars 18 are pushed in from this opening. These must then be bent downwards, which is not an optimal solution from the point of view of adhesion, but it is a compromise that this construction requires. During casting, the ends of the cavities in the hollow slabs are filled with concrete, after which they will withstand longitudinal compression.

Det skal specielt bemærkes, at de sammensatte bjælkeprofiler også 30 ,kan samles af to eller flere dele, i hvilket tilfælde boltene, som anvendes til at samle dem, kan virke som de tidligere nævnte tværgående stålstænger, med hvilke midler en eller flere af de forannævnte opgaver kan udføres. På den anden side kan hver tværgående stang eller bolt kun strække sig til den ene side af bjælken, men 35 når efter hinanden følgende stænger strækker sig til hver side efter tur, opnås armering på begge sider i denne henseende.In particular, it should be noted that the composite beam profiles 30 may also be assembled by two or more parts, in which case the bolts used to assemble them may act as the aforementioned transverse steel bars by which means one or more of the aforementioned tasks can be performed. On the other hand, each transverse rod or bolt can only extend to one side of the beam, but when successive rods extend to each side in turn, reinforcement is achieved on both sides in this regard.
