DK 159562 BDK 159562 B
Opfindelsen angår et præfabrikeret pladeelement af komposit-typen til anvendelse inden for byggeindustrien, f.eks. som bjælkelag, i vægge og lofter, og af den i krav l's indledning angivne art.The invention relates to a prefabricated composite type element for use in the construction industry, e.g. as beams, in walls and ceilings, and of the kind specified in the preamble of claim 1.
5 Præfabrikerede bygningselementer tilstræbes i stadigt større udstrækning inden for byggesektoren, og flere forskellige typer forekommer på markedet idag. De bjælkelagselementer, som anvendes, er letbetonelementer eller er opbygget af tynde betonlag i kombination med tværgående træstykker.5 Prefabricated building elements are increasingly being sought in the construction sector, and several different types are on the market today. The joists used are lightweight concrete elements or are made up of thin concrete layers in combination with transverse pieces of wood.
10 Ulempen med disse kendte elementer er dog bl.a. at de er begrænset fritbærende og har en forholdsvis høj egenvægt.10 However, the disadvantage of these known elements is, inter alia, that they are limited free-bearing and have a relatively high self-weight.
Andre ulemper ved forud kendte elementer af denne art er, at installation af el- og VVS-amlæg besværliggøres, og at visse begrænsninger:fremstår, når det gælder om at vælge ma- 15 teriale til en bærende konstruktion oven over et bjælkelag af denne type.Other disadvantages of prior art elements of this kind are that installation of electrical and plumbing systems is made difficult and that certain limitations: appear when it comes to choosing material for a supporting structure over a beam layer of this type .
På markedet findes også præfabrikerede bjælkelagselementer helt fremstillet af træ, som dog praktisk taget udelukkende anvendes af fabrikanter af monteringsfærdige træhuse.Also available on the market are prefabricated joists made entirely of wood, which are, however, practically exclusively used by manufacturers of ready-made wooden houses.
20 Fra tysk offentliggørelsesskrift nr. 2 413 645 kendes en betonplade med hatteformede bjælker, som er anbragt på betonpladens underside. Problemet med at kunne optage bøjningsmomenter er imidlertid ikke bilevfet løst med dette element, der således ikke er egnet til at fungere som fritbærende bjælkelagselement.20 From German Publication No. 2,413,645, a concrete slab with hat-shaped beams is known, which is placed on the underside of the concrete slab. However, the problem of being able to absorb bending moments is not solved with this element, which is thus not suitable to function as a freestanding beam layer element.
25 Deti eri'jformålet med opfindelsen at tilvejebringe et element med så stor fleksibilitet som muligt kombineret med lav egenvægt.It is the object of the invention to provide an element of as much flexibility as possible combined with low self-weight.
Dette opnås,i idét pladeelementet ifølge opfindelsen er ejendommeligt ved, at elementet yderligere omfatter to tværgåen- 30 de, armerede, støbte betonbjælker, som er^anbragt ved hverThis is achieved in that the slab element according to the invention is characterized in that the element further comprises two transverse, reinforced, cast concrete beams, which are arranged at each

Ifølge en foretrukket udførelsesform for opfindelsen er pla-den og de støbte bjælker fremstillet af letbeton.According to a preferred embodiment of the invention, the slab and the cast beams are made of lightweight concrete.
Tyndpladeprofilerne udgør elementets primære bøjspændings-optagende enheder, de støbte kortendebjælker udgør overfladeelementets primære understøtning, og de støbte mellembjælker udgør overfladeelementets primære sammenføjnings- 1° » .The thin-plate profiles constitute the element's primary bending stress-absorbing units, the molded short end beams constitute the primary support of the surface element, and the molded intermediate beams constitute the primary joint of the surface element 1 °.
enheder.units.
Mellembjælkerne giver desuden nødvendig indre afstivning og kan også fungere som mellemstøtte, når overfladeelementerne er oplagt på flere end to understøtninger.The intermediate beams also provide necessary internal stiffening and can also act as intermediate supports when the surface elements are laid on more than two supports.

Pladetykkelsen skal fortrinsvis ligge inden for intervallet 20 - 100 mm.The plate thickness should preferably be within the range of 20 - 100 mm.
Pladen og de støbte bjælker skal være armerede. Når flere end to understøtninger udnyttes, kompletteres pladensThe plate and the cast beams must be reinforced. When more than two supports are utilized, the plate is supplemented

Ifølge yderligere en foretrukket udførelsesform for opfindelsen er de tværgående bjælkers armering heltrukket fra elementets ene langside til den anden og løber da gennem i tyndpladeprofilerne udstansede huller.According to a further preferred embodiment of the invention, the reinforcement of the transverse beams is fully extended from one longitudinal side to the other and then runs through holes punched in the thin plate profiles.

De mellemliggende støbte tværbjælker kan ved deres udformning gøres fritbærende over forholdsvis store spændvidder. Dette medfører bl.a., at elementerne bliver stivere, dvs. mindre nedbøjning og fjedren, samt at de mellemlig-30 gende understøtninger, når overfladeelementet anvendes som bjælkelag oplagt på flere end to understøtninger, kan udgøres af en søjle. Den indbyrdes afstand mellem søjlerne kan da gå op til ca. 4 meter.The intermediate molded crossbeams can be rendered free-bearing over relatively large widths in their design. This means, among other things, that the elements become stiffer, ie. less deflection and the spring, and the intermediate supports when the surface element is used as a beam layer laid on more than two supports can be constituted by a column. The distance between the columns can then go up to approx. 4 meters.

Eksempel på konstruktioner, hvortil det omhandlede overfladeelement kan anvendes, er fladbærelag, såsom bjælkelag, loftlag, tage, altaner, lette brokonstruktioner og vægge, såsom facadeelementer til beboelsesbygninger, 5 industribygninger og landbrugsbygninger og som støtte element, f.eks. i bassiner og silobygninger.Examples of structures to which the present surface element can be used are flat support layers such as beams, ceilings, roofs, balconies, lightweight bridge structures and walls, such as facade elements for residential buildings, industrial buildings and agricultural buildings and as a supporting element, e.g. in basins and silo buildings.
Overfladeelementet ifølge opfindelsen opviser en række fordele. Det har stor bæreegenskab og kan gøres fritbærende med store spændvidder i forhold til egenvægten. Med en 2 o 2 lø egenvægt på ca. 0,7 - 0,9 kN/m og en nyttelast på 1,5 kN/m kan spændvidder op til mindst 8,4 m klares, dvs., svarende til bredden på et normalt småhus.The surface element according to the invention has a number of advantages. It has great carrying capacity and can be carried freely with large widths in relation to the weight. With a 2 o 2 run weight of approx. 0.7 - 0.9 kN / m and a payload of 1.5 kN / m can span up to at least 8.4 m, ie, corresponding to the width of a normal small house.
Endvidere har overfladeelementet ifølge opfindelsen stor 19 fleksibilitet, og et og samme element, som kan klare store, frie spændvidder, kan også lægges op som kontinuerlig bjælke på flere støtter eller fungere som konsol ved f.eks, en indspændt altan eller en bro.Furthermore, the surface element according to the invention has great flexibility and one and the same element, which can handle large, free spans, can also be laid up as a continuous beam on several supports or act as a bracket, for example, on a suspended balcony or a bridge.
Samme element, som kan optage vertikale byrder i f.eks. et bjælkelag, kan anvendes som fgcedeelementi f.eks. en 20 industrihal, og meget store højder på elementerne kan derved klares. Begrænsningerne ligger hovedsageligt i transportapparaterne, men højder på 12-15 m kan klares.Same element that can absorb vertical loads in e.g. a beam layer, can be used as a floor element e.g. a 20 industrial hall, and very high heights of the elements can thereby be cleared. The restrictions are mainly in the conveyors, but heights of 12-15 m can be handled.
Når overfladeelementerne anvendes som bjælkelag oplagt på flere end to understøtninger, dvs. som kontinuerlig 25 bjælke, kan midterunderstøtningen udgøres af søjler med en indbyrdes afstand på ca. 4 meter på grund af, at overfladeelementets mellemliggende tværbjælker kan gøres fritbærende over forholdsvis store spændvidder.When the surface elements are used as joists laid on more than two supports, ie. as a continuous beam, the center support can be made up of columns with a spacing of approx. 4 meters because the intermediate cross beams of the surface element can be freely supported over relatively large spans.
Ved anvendelse af overfladeelementet ifølge opfindelsen 3Q som bjælkelag i f.eks. småhuse, har det også følgende fordele. Form og konstruktion tillader vindtætte tilslut- 4Using the surface element according to the invention 3Q as a beam layer in e.g. cottages, it also has the following advantages. Form and construction allow windproof connections 4

ninger mod ydervæggene og frembyder ingen begrænsninger i valg af materiale i bærende vægge oven over bjælkelaget. Stor frihed ved el- og VVS-installationer foreligger takket være pladeprofilernes udformning. Endvidere er ned-^ bøjning og fjedren ringe i forhold til den frie spænd vidde, og elementet viser også g0d egnethed for bearbejdning ved, at det lader sig gøre at sømme, skrue, save og hugge.against the outer walls and present no restrictions on the choice of material in load-bearing walls above the joists. Great freedom in electrical and plumbing installations exists thanks to the design of the plate profiles. Furthermore, deflection and spring are poor in relation to the free span, and the element also shows good suitability for machining by being able to nail, screw, saw and chop.
Yderligere ejendommeligheder ved elementet ifølge opfindelsen fremgår af de uselvstændige krav.Further peculiarities of the element according to the invention appear from the dependent claims.

Opfindelsen vil nu blive nærmere forklaret under henvisning ’til tegningen, som viser en udførelsesform for elementet ifølge opfindelsen, idet: 15 fig. 1 viser et perspektivbillede af et overfladeelement ifølge opfindelsen, og fig. 2 viser et tværsnit af elementet taget langs linien II-II i fig. 1.The invention will now be explained in more detail with reference to the drawing, which shows an embodiment of the element according to the invention, in which: 1 shows a perspective view of a surface element according to the invention, and FIG. 2 shows a cross section of the element taken along line II-II of FIG. First
I fig. 1 vises overfladeelementet ifølge opfindelsen, betegnet med 1. En støbt plade 2 danner elementets-øvexste overflade 3. På langs gående tyndpladeprofiler 4 strækker sig over hele overfladeelementets længde og er ved enderne indstøbte i tværgående, støbte bjælker 5, 6 af beton.In FIG. 1, the surface element according to the invention is indicated by 1. A molded plate 2 forms the outermost surface of the element 3. Longitudinal thin plate profiles 4 extend over the entire length of the surface element and are embedded at the ends in transverse cast beams 5, 6 of concrete.
Mellem de tværgående bjælker ved overfladeelementets kortender er der anordnet yderligere tværgående bjælker 7, 8, 25* også disse af beton.Between the transverse beams at the short ends of the surface element, further transverse beams 7, 8, 25 * are also provided of concrete.
I fig. 2 vises et tværsnit af overfladeelementet ifølge opfindelsen, taget langs linien II-II i fig. 1. Heraf fremgår, at pladen 2 er armeret og fortrinsvis med et rudearmeringsnet 9. Også de tværgående bjælker 5-8 er 30 armerede. For opnåelse af maksimal holdbarhed og styrke i de støbte, tværgående bjælker er disse fortrinsvis ar- 5In FIG. 2 shows a cross section of the surface element according to the invention, taken along line II-II in FIG. 1. From this it can be seen that the plate 2 is reinforced and preferably with a pane reinforcement mesh 9. Also the transverse beams 5-8 are reinforced. For maximum durability and strength in the molded transverse beams, these are preferably mounted.

merede med en armering, som er heltrukket fra elementets ene langside til den anden, og som derved løber gennem huller, som er udstansede i tyndpladeprofilerne.with a reinforcement, which is completely drawn from one longitudinal side to the other, and thereby runs through holes punched in the thin plate profiles.
De på langs gående profiler udgøres af tyndpladeprofiler 4a-4d, som i den viste udførelse er udformet med en krop 10 med tremmeværkslignende konstruktion. Profilens frie kant har en U-formet kantafstivning 11, mens dens indstøbte kant har en enkelt foldning med huller til samvirke mellem beton og plade. Ved de skråstivere i profilerne, som danner tremmeværket, er. pladen udadbøjet 12a-d, hvorved der opnås en yderligere afstivning.The longitudinal profiles are made up of thin-plate profiles 4a-4d, which in the illustrated embodiment are formed with a body 10 of truss-like construction. The free edge of the profile has a U-shaped edge support 11, while its embedded edge has a single fold with holes for interaction between concrete and slab. By the oblique struts in the profiles that form the trunk are. the plate bends outwardly 12a-d, thereby providing a further stiffening.
Som omtalt i indledningen er ifølge en foretrukket udførelsesform for opfindelsen såvel plade som tværbjælker støbt af letvægtsbeton. Pladen og bjælkerne er armerede, 15 hvilket også er nævnt ovenfor, passende med et 4 mm armeringsnet .As mentioned in the introduction, according to a preferred embodiment of the invention, both slab and cross beams are molded from lightweight concrete. The plate and beams are reinforced, which is also mentioned above, suitably with a 4 mm reinforcement mesh.

Letbetonens densitet gåråop til ca. 800-1100 kg/m , hvilket svarer til ca. to gange træets densitet, men mindre end halvdelen af densiteten for almindelig beton. Dette gør, at overfladeelementet ifølge opfindelsen får en 20 ,2 egenvægt, som er så lav som ca. 0,70-0,90 kN/m , og den fritbærende længde kan gøres så lang som 8,4 m ved en nyttelast på 1,5 kN/m , dvs. hvad der kræves ifølge bygge-normerne for småhusbjælkelag. Dette skal sammenlignes med et element med lignende udformning fremstillet af konventionel beton, hvilket skulle få en eqenvæqt, som over-25 stiger nyttelasten.The density of lightweight concrete goes up to approx. 800-1100 kg / m, which corresponds to approx. twice the density of the wood, but less than half the density of ordinary concrete. This causes the surface element according to the invention to have a 20, 2 eigenweight which is as low as approx. 0.70-0.90 kN / m, and the free-bearing length can be made as long as 8.4 m at a payload of 1.5 kN / m, ie. what is required according to the building standards for small-house beams. This is to be compared to a similarly constructed element made of conventional concrete which should have an even weight exceeding the payload.
Pladen 2 danner således elementets overflade 3 og fordeler nyttelasten og optager trykspændinger fra bøjende momenter. De på langs gående tyndpladeprofiler har til 30 opgave at optage bøjnings- og forskydningsspændinger, mens de tværgående, mellem kortendebjælkerne liggende bjælker bidrager med en indre afstivning af det enkelte 6The plate 2 thus forms the surface 3 of the element and distributes the payload and absorbs compressive stresses from bending moments. The longitudinal thin plate profiles have 30 tasks for absorbing bending and shear stresses, while the transverse beams located between the short end beams contribute to an internal stiffening of the individual 6

element samt muliggør sammenføjning af flere elementer på en sådan måde, at et vist moment kan optages også af disse mellemliggende bjælker. De tværgående, mellemliggende bjælker har desuden stor betydning for elementets håndter- barhed, f.eks. ved vending og løftning.element as well as enabling multiple elements to be joined in such a way that a certain amount of torque can be absorbed by these intermediate beams as well. The transverse intermediate beams are also of great importance for the manageability of the element, e.g. by turning and lifting.

De ved elementets korte ender støbte bjælker har flere forskellige for opfindelsen væsentlige funktioner. Disse bjælker er sammenholdende og hviler mod understøtningerne, der som nævnt kan udgøres af parallelle, på langs gående vægge i et småhus. Ved at pladeprofilerne er støbt ind i disse, tværgående kortendebjælker, kan disse afstive tyndpladeprof ilerne samtidigt med, at de tætner mod understøtningen og kantbeklædningen. Desuden danner de understøtning for bærende vægge i etagen oven over bjælkelaget, når overfladeelementet anvendes som bjælkelag.The beams cast at the short ends of the element have several different functions essential to the invention. These beams are coherent and rest against the supports, which, as mentioned, can be made up of parallel, longitudinal walls in a small house. By molding the plate profiles into these transverse short end beams, these can support the thin plate profiles while simultaneously sealing against the support and edge cladding. In addition, they form support for supporting walls in the floor above the beam layer when the surface element is used as a beam layer.
1515
Med en pladetykkelse på 30-60 mm opnås alle de ovenfor beskrevne fordele, samtidig med, at der fås et element med minimal vægt.With a sheet thickness of 30-60 mm, all the advantages described above are obtained, while obtaining a minimum weight element.
Ved fremstillingen af overfladeelementet ifølge opfindelsen sammenstøbes betonpladen og de to kortendebjælker samt tværbjælkerne af beton med tyndpladeprofilerne på en sådan måde, at fuld samvirken mellem betonen og tyndplade-profilerne opnås. I tilfælde, hvor overfladeelementet er beregnet til at blive anvendt som bjælkelagselement, kan tyndpladeprofilerne ifølge en udførelsesform for opfindelsen forspændes, så at de udøver en konstant bøje-spænding på det færdige element.In the manufacture of the surface element according to the invention, the concrete slab and the two short end beams as well as the cross beams of concrete are molded with the thin slab profiles in such a way that full interaction between the concrete and the slab profiles is achieved. In cases where the surface element is intended to be used as a beam layer element, the thin plate profiles according to one embodiment of the invention can be prestressed so that they exert a constant bending stress on the finished element.
For fiksering og distancering af tyndpladeprofilerne i den støbeform, som anvendes, og i hvilken elementet fremstilles med den øverste overflade nedad, forsynes tyndpladeprof ilernes på langs gående indstøbningskant med ind-30 fæstningselementer, i det mindste et i hver ende. Disse elementer kan bagefter også udnyttes for løftning af de færdige overfladeelementer.For fixing and spacing the thin plate profiles in the mold used and in which the element is made with the upper surface facing down, the thin plate profiles along the longitudinal molding edge are provided with fastening elements, at least one at each end. Afterwards, these elements can also be utilized for lifting the finished surface elements.
77
DK 159562 BDK 159562 B
De mellemliggende tværbjælker af beton forsynes i begge ender med indstøbte befæstningeselementer, som ved montering af de færdige overfladeelementer ifølge opfindelsen anvendes tilisammenføjning af op til hinanden liggende overfladeelementer.The intermediate concrete beams are provided at both ends with molded fastening elements which, when mounting the finished surface elements according to the invention, are used to join adjacent surface elements.
Ved fremstillingen kan den støbte betonplade også forsynes med materialer til optagelse og afgivelse af varmeenergi, og endvidere kan det færdige overfladeelement forsynes med varme- oq/eller lydisolation i rummet mellem pladeprofi- 10 lerne.In the manufacture, the cast concrete slab can also be provided with materials for absorbing and delivering heat energy, and furthermore, the finished surface element can be provided with heat and / or sound insulation in the space between the slab profiles.
Med hensyn til tyndpladeproflierne vises kun en tænkt udførelsesform på tegningen. Det skal dog bemærkes, at det udstansede mønster kun er fremkommet for at opnå lavest mulig egenvægt og lavest mulig materialeforbrug samt 15 delvis for at tilvejebringe størst mulig frihed ved installationer. I visse tilfælde kan det dog være formålstjenligt at udnytte en profil med ugennnembrudt li-v eller med andet mønster.With regard to the thin plate profiles, only one intended embodiment is shown in the drawing. It should be noted, however, that the die-cut pattern is only produced to achieve the lowest possible weight and lowest possible material consumption, and partly to provide maximum freedom in installations. In some cases, however, it may be expedient to utilize a profile with an unbroken body or other pattern.
I det viste udførelseseksempel har profilernes fri® kant 20 en U-formet kantafstivning 11. Dette er imidlertid ikke helt nødvendigt, idet kantafstivningen kan bestå alf en enkelt foldning.In the illustrated embodiment, the free edge of the profiles 20 has a U-shaped edge support 11. However, this is not absolutely necessary, since the edge support can consist of a single fold.
Den indstøbte, på langs gående kant kan også have tein ll-formet kantafstivning, selv om den i det viste eksempel 25 udgøres af en enkelt foldning med udstansninger føir at tilvejebringe størst mulig- samvirken mellem plade (øg beton.The embossed, longitudinal edge may also have tine II-shaped edge stiffening, although in the example shown 25 it is constituted by a single folding with punches to provide the greatest possible interaction between slab (reinforced concrete).
Tyndpladeprofilernes tværsnit kan også varieres, hvorved en foretrukket form er en Z-profil, men også en U-iprofil 30 fungerer tilfredsstillende.The cross-sectional profiles of the thin-plate profiles can also be varied, whereby a preferred shape is a Z-profile, but also a U-profile 30 functions satisfactorily.
