Opfindelsen angår en sammensat gulvkonstruktion ifølge krav l's indledning.The invention relates to a composite floor structure according to the preamble of claim 1.
Såkaldte sammensatte gulvkonstruktioner er støbt ved hjælp af en profileret plade, som en arbejdsplatform og en permanent 5 form. Når den støbte sammensætning/beton er hærdet samvirker den profilerede plade med betonen. Den profilerede plade er normalt ikke i stand til at bære· lasten af den våde beton, som udlægges i forbindelse med betonstøbningsoperationer, hvorfor det er nødvendigt at understøtte konstruktionen ne-10 denfra. Opgaven med at understøtte eller tilsvarende at bære en for nylig støbt betongulvkonstruktion er både dyr og tidskrævende. Derudover er det kun muligt at støbe et gulv eller dæk ad gangen, da det er nødvendigt, at et underliggende gulv opnår en vis grad af bærbarhed eller mekanisk styrke før det 15 er i stand til at modstå de kræfter, der udøves af et overliggende gulv og overføres via støtteorganer eller lignende bæreorganer, der anvendes til at bære det. Bygningskonstruktionstidsplanen som helhed styres således i det væsentlige af processen med at støbe betongulvkonstruktionerne.So-called composite floor structures are molded using a profiled sheet, such as a work platform and a permanent mold. When the cast composition / concrete is cured, the profiled plate interacts with the concrete. The profiled slab is usually not capable of carrying the load of wet concrete laid in connection with concrete casting operations, which is why it is necessary to support the structure from below. The task of supporting or correspondingly carrying a recently cast concrete floor construction is both expensive and time consuming. In addition, it is only possible to mold one floor or deck at a time, as it is necessary for an underlying floor to achieve some degree of portability or mechanical strength before it is able to withstand the forces exerted by an overlying floor. and transmitted via supporting means or similar supporting means used to support it. Thus, the building construction schedule as a whole is essentially guided by the process of casting the concrete floor structures.
20 Fra WO Al 84/02734 kendes en kassette til dannelse af en form til brug ved fremstilling af lofter. Kassetten består af en nedre plade og en øvre plade. Den nedre plade har bukkede sideflige, som åbner mulighed for dels sammenkobling af flere kassetter og dels indstøbning i beton. Efter anbringelse af 25 kabler eller isolerende materiale oven på den nedre plade fastgøres den øvre plade ved under snapvirkning at blive ført i indgreb med den nedre plades sideflige.20 From WO A1 84/02734 a cassette for forming a mold for use in the manufacture of ceilings is known. The cassette consists of a lower plate and an upper plate. The lower plate has curved side tabs, which allow for the interconnection of several cassettes and partly for concrete casting. After placing 25 cables or insulating material on top of the lower plate, the upper plate is fastened by engaging the side plate with the side plate under snap action.
Formålet med opfindelsen er at tilvejebringe en sammensat gulvkonstruktion, som under betonstøbningsstadiet er i stand 30 til at modstå samme bærespændinger, som den færdige gulvkonstruktion, således at behovet for at støtte konstruktionen nedenfra elimineres. Dette formål opnås med en sammensat gulvkonstruktion, som har de i de efterfølgende krav angivne karakteristiske træk.The object of the invention is to provide a composite floor structure which, during the concrete casting stage, is able to withstand the same load-bearing stresses as the finished floor construction, so that the need to support the construction from below is eliminated. This object is achieved with a composite floor structure which has the characteristic features of the following claims.

En fordel, der opnås ved hjælp af opfindelsen, er at den muliggør, at en bygning kan rejses på en meget mere effektiv måde end det tidligere har været muligt som følge af den kendsgerning, at det ikke længere er nødvendigt at afstive 5 eller understøtte gulvkonstruktionen nedenfra. F.eks. muliggør opfindelsen, at gulvkonstruktionerne i en fleretages bygning kan fremstilles kontinuerligt helt op til bygningens tag, idet alle gulvkonstruktionerne støbes efterhånden i rækkefølge. Opfindelsen muliggør således besparelse af tiden, og 10 at det involverede arbejde kan udføres på en mere effektiv og rationel måde. En sammensat gulvkonstruktion ifølge opfindelsen kræver mindre armering og betyder derfor besparelser som følge af mindre materialeforbrug.An advantage obtained by means of the invention is that it enables a building to be erected in a much more efficient way than has previously been possible due to the fact that it is no longer necessary to stiffen 5 or support the floor construction from below. Eg. The invention enables the floor structures in a multi-storey building to be manufactured continuously up to the roof of the building, all the floor structures being gradually molded in sequence. The invention thus enables saving of time and the work involved can be carried out in a more efficient and rational way. A composite floor construction according to the invention requires less reinforcement and therefore means savings due to less material consumption.
En udførelsesform for opfindelsen beskrives nærmere nedenfor 15 under henvisning til tegningen, hvor fig. 1 viser en del af en sammensat gulvkonstruktion ifølge opfindelsen, set i tværsnit, fig. 2 en perspektivisk afbildning af den del af gulvkonstruktionen, der er vist i fig. l, og 2 0 fig. 3 og 4 tværsnit af dele af andre udførelsesformer for den sammensatte gulvkonstruktion ifølge opfindelsen.An embodiment of the invention is described in more detail below with reference to the drawing, in which: FIG. 1 is a cross-sectional view of part of a composite floor structure according to the invention; FIG. 2 is a perspective view of the part of the floor structure shown in FIG. 1, and FIG. 3 and 4 are cross sections of parts of other embodiments of the composite floor construction according to the invention.
Opfindelsen indebærer, at der først konstrueres en gulvkonstruktion af præfabrikerede sandwichelementer, som fungerer som en form, og som er konstrueret til at samvirke med beto-25 nen på en sådan måde, at der opnås en ideel sammensat gulvkonstruktion. Selvom sandwichelementerne er tilstrækkeligt stærke og stive til at modstå kortvarige belastninger vil elementernes kernemateriale krybe med tiden, hvorved sandwichelementerne bliver uegnede som langtids-gulvkonstruktio-30 ner.The invention involves first constructing a floor structure of prefabricated sandwich elements which act as a mold and which are designed to cooperate with the concrete in such a way that an ideal composite floor structure is obtained. Although the sandwich elements are sufficiently strong and rigid to withstand short-term loads, the core material of the elements will shrink over time, making the sandwich elements unsuitable as long-term floor structures.
Fig. 1 viser to op til hinanden stødende sandwichelementer 1, 3 DK 174207 B1 som, selvom det ikke er vist, kan placeres på et antal primærbjælker, og som er indbyrdes forbundet langs deres lange sidekanter, således at der dannes en støbeplatform.FIG. 1 shows two adjacent sandwich elements 1, 3, which, although not shown, can be placed on a number of primary beams and which are interconnected along their long side edges to form a molding platform.
Sandwichelementet 1 kan være præfabrikeret og omfatte en øvre 5 plade 2, fremstillet af f.eks. metalplade eller stålplade, en kernedel 3, fremstillet af et letvægtsmateriale, såsom ekspanderet polystyren, polyurethan eller mineraluld, og en nedre plade 4, fremstillet af f.eks. metalplade eller stål-plade. Pladerne 2 og 4 er forbundet med kernen 3 ved hjælp af 10 limning, sammensmeltning eller adhæsion.The sandwich element 1 may be prefabricated and comprise an upper plate 5 made of e.g. a sheet metal or steel sheet, a core portion 3, made of a lightweight material such as expanded polystyrene, polyurethane or mineral wool, and a lower sheet 4 made of e.g. metal plate or steel plate. The plates 2 and 4 are connected to the core 3 by means of bonding, fusion or adhesion.
Langs kernes 3 langsgående sidekanter er der tilvejebragt en underskæring 10. Den nedre plades 4 langsgående sidekanter har en udadragende del 11, som ender i en vinkelbukket endedel, som omfatter betonindgrebsorganer i form af huller 13, 15 således at der opnås det bedst mulige indgreb af elementet med betonen. Den øvre plade 2 er langs dens langsgående sidekanter forsynet med en udadragende del 14, som er bukket lidt nedad, og som også har betonindgrebsorganer i form af huller 15 til opnåelse af det bedst mulige betonindgreb.Along the longitudinal side edges of the cores 3, an undercut 10 is provided. The longitudinal side edges of the lower plate 4 have an outwardly projecting portion 11 which ends in an angled end portion which comprises concrete engaging means in the form of holes 13, 15 to obtain the best possible engagement of the element with the concrete. The upper plate 2 is provided along its longitudinal side edges with an outwardly extending portion 14, which is slightly bent, and which also has concrete engaging means in the form of holes 15 for obtaining the best possible concrete engagement.
20 Sandwichelementerne 1 anbringes på primærbjælkerne og forbindes med hinanden ved hjælp af en forbindelsesliste 20, som er skruet fast til de udadragende dele 11 af de op til hinanden stødende sandwichelementer 1, således som det fremgår af fig.20 The sandwich elements 1 are placed on the primary beams and connected to one another by means of a connecting strip 20 which is screwed to the outwardly extending parts 11 of the adjacent sandwich elements 1, as can be seen in FIG.
1 og 2. Når sandwichelementerne er forbundet med hinanden, 25 enten ved hjælp af forbindelseslisterne eller ved direkte at være skruet fast til hinanden, er der tildannet en stiv pladelignende konstruktion, som stabiliserer hele rammeværket, indtil det efterfølgende påstøbte beton har fået tilstrækkelig mekanisk styrke.1 and 2. When the sandwich elements are connected to each other, either by means of the connecting strips or by being screwed directly to each other, a rigid plate-like structure is formed which stabilizes the entire framework until the subsequent cast concrete has sufficient mechanical strength. .
30 De således indbyrdes forbundne sandwichelementer l er herefter klar til støbningen af beton 90, eventuelt efter udlægningen af yderligere armeringer (ikke vist), idet betonen udfylder spalterne imellem de op til hinanden stødende sand- DK 174207 B1 4 wichelementers 1 kerner 3 til et niveau 91, som er antydet ved hjælp af en. stiplet linie i fig. 1. Efter påstøbningen af betonen 90 er der opnået en yderst effektiv sammensat gulvkonstruktion, hvori betonen 90 indgriber med de udadragende 5 dele 11 af den nedre plade 4, og hvori betonen 90 også er i indgreb med de udadragende dele 14 af den øvre plade 2. Den nedre plade optager trækkræfter fra bøjningsmomenter. Den ovenpå liggende beton optager trykkræfter fra bøjningsmomenter, og den imellem sandwichelementerne værende beton over-10 fører forskydningskræfter imellem den nedre plade og det ovenpå liggende beton, eventuelt forstærket med forskydningsarmeringer. Kernens 3 eventuelle tendens til at sætte sig modvirkes af betonens 90 indgreb med underskæringer 10 i kernerne 3.30 The interconnected sandwich elements 1 are then ready for the casting of concrete 90, possibly after the laying of additional reinforcements (not shown), the concrete filling the gaps between the adjacent sandy cores 3 to a level 91, which is suggested by one. dotted line in fig. 1. After the casting of the concrete 90, a highly effective composite floor structure is obtained in which the concrete 90 engages with the protruding 5 parts 11 of the lower plate 4 and wherein the concrete 90 also engages the protruding parts 14 of the upper plate 2. The lower plate absorbs tensile forces from bending moments. The concrete on top absorbs compressive forces from bending moments and the concrete between the sandwich elements transfers shear forces between the lower plate and the concrete on top, possibly reinforced with shear reinforcements. The tendency of the core 3 to settle is counteracted by the engagement of the concrete 90 with cuts 10 in the cores 3.
15 Fig. 3 viser en anden udførelsesform, hvori de nedre pladers 4' udragende dele 11' er bukket således, at de muliggør, at op til hinanden stødende sandwichelementer 1' kan skrues sammen uden brug af separate forbindelseslister. De udragende dele 11' og 14' af denne udførelsesform har også betonind-20 grebsorganer i form af huller 13' og 15'. Betonniveauet 91 er vist ved hjælp af en stiplet linie.FIG. 3 shows another embodiment in which the protruding parts 11 'of the lower plates 4' are bent so that adjacent sandwich elements 1 'can be screwed together without the use of separate connecting strips. The protruding parts 11 'and 14' of this embodiment also have concrete engaging means in the form of holes 13 'and 15'. The concrete level 91 is shown by a dotted line.
Fig. 4 viser en anden udførelsesform, hvori de udragende dele 11" af de nedre plader 4" er bukket således opad, at betonindgrebsorganerne/ -hullerne 13" vil være placeret over den 25 øvre plades 2" lodrette niveau. De udragende dele 14" af de øvre plader 2" er alle bukket således opad, at betonindgrebs-organerne/ -hullerne 15" vil være placeret over den øvre plades 2" lodrette niveau. Denne udførelsesform muliggør opnåelse af tæt anlæg imellem de respektive sandwichelementers 1” 30 langsgående sidekanter. Dette muliggør samtidigt, at sammenhængende eller op til hinanden stødende sandwichelementer 1" kan skrues sammen ved deres udragende dele 11" inden for området af deres indbyrdes anlæg. Betonniveauet 91 er vist ved hjælp af en stiplet linie. Figuren viser også armeringsstæn-35 ger 80, som strækker sig igennem huller 13". I tilfældet af 5 DK 174207 B1 denne udførelsesfonn optager den udadfoldede nedre plade de forskydningskræfter, som virker imellem den nedre plade og det støbte beton.FIG. 4 shows another embodiment in which the protruding parts 11 "of the lower plates 4" are bent upwards so that the concrete engaging means / holes 13 "will be placed above the vertical level of the upper plate 2". The projecting portions 14 "of the upper plates 2" are all bent upwardly so that the concrete engaging means / holes 15 "will be placed above the vertical level of the upper plate 2". This embodiment allows for tight fitting between the longitudinal side edges of the respective sandwich elements 1 ”30. This simultaneously allows coherent or adjacent sandwich elements 1 "to be screwed together by their protruding parts 11" within the area of their mutual abutment. The concrete level 91 is shown by a dotted line. The figure also shows reinforcing bars 80 extending through holes 13 ". In the case of this embodiment, the unfolded lower plate absorbs the shear forces acting between the lower plate and the cast concrete.
I overensstemmelse med den foreliggende opfindelse er der 5 opnået en sammensat gulvkonstruktion, hvori det overliggende beton optager trykkræfter og de respektive sandwichelementers nedre plade optager trækkræfter. Sandwichelementets kerne fungerer i princippet som letvægtspiller, som åbner mulighed for at der opnås en gulvkonstruktion af en passende tykkelse 10 med hensyn til stivhed og styrke, uden at den bliver unødvendig tung. Det ligger naturligvis inden for opfindelsens idé at udelukke de udadragende dele og indgrebsorganerne på den øvre plade.In accordance with the present invention, a composite floor structure is obtained in which the overlying concrete absorbs compressive forces and the lower plate of the respective sandwich elements absorbs tensile forces. In principle, the core of the sandwich element functions as a lightweight peeler, which allows for a floor construction of a suitable thickness 10 in terms of rigidity and strength to be obtained, without being unnecessarily heavy. It is, of course, within the idea of the invention to exclude the protruding parts and the engaging means of the upper plate.
Derudover kan naturligvis den øvre plade, kernen og den nedre 15 plade i sandwichelementet være af andre materialer end dem, der er nævnt ovenfor, uden at man herved afviger fra opfindelsens idé.In addition, of course, the upper plate, the core and the lower plate of the sandwich element may be of materials other than those mentioned above, without departing from the spirit of the invention.
Det ligger også inden for opfindelsens idé at ændre konstruktionen af de udragende dele i forbindelse med både den nedre 20 plade og den øvre plade. Konstruktionen af betonindgrebsorganerne kan naturligvis også ændres, og de viste huller kan f.eks. erstattes med tunger, tappe, prægninger, foldninger eller lignende .It is also within the idea of the invention to change the construction of the protruding parts in connection with both the lower plate and the upper plate. The structure of the concrete engagement means can of course also be changed, and the holes shown can e.g. be replaced with tongues, pins, embossings, folds or the like.
Den øvre plade kan også være bibragt en profileret struktur, 25 som fremmer dens evne til at optage trykkræfter, der optræder, medens betonen støbes. Om ønsket kan den øvre plade være forsynet med prægninger over hele dens overflade med det formål at fremme samvirkningen imellem den sammensatte gulvkonstruktions komponenter. Om ønsket kan den nedre plade også 30 være givet en profileret struktur og forsynet med prægninger ud over det, der er vist som eksempel i figurerne. Den sammensatte gulvkonstruktion ifølge opfindelsen kan om nødvendigt være yderligere forstærket ved at inkludere armerings- DK 174207 B1 6 stænger eller en anden passende form for armering.The upper plate may also be provided with a profiled structure which promotes its ability to absorb compressive forces occurring while casting the concrete. If desired, the upper plate may be embossed over its entire surface for the purpose of promoting the interaction between the components of the composite floor structure. If desired, the lower plate 30 may also be given a profiled structure and provided with embossings in addition to that shown by way of example in the figures. If necessary, the composite floor structure of the invention may be further reinforced by including reinforcing bars or other suitable form of reinforcement.
Opfindelsen er derfor ikke begrænset til de viste og beskrevne udførelsesformer, da ændringer og modifikationer kan foretages inden for de efterfølgende kravs beskyttelsesområde.The invention is therefore not limited to the embodiments shown and described, since modifications and modifications may be made within the scope of the appended claims.
