(64) Bærende element, især til lofts- og tagkonstruktioner.(64) Support element, especially for ceiling and roof structures.

Den foreliggende opfindelse angår et bærende element, især til lofts- og tagkonstruktioner, hvor i hvert fald trækzonen er placeret i en armeret betondrager, som i hvert fald for trækzonens vedkommende er indstøbt i et bjælkeformet legeme .The present invention relates to a supporting element, in particular to ceiling and roof structures, in which at least the towing zone is located in a reinforced concrete carrier which is at least for the towing zone embedded in a beam-shaped body.

Det er til fremstilling af dækkonstruktioner kendt at benytte hullegemer eller -sten af tegl eller beton. Disse elementer udlægges på en forskalling, hvorefter der i hulrummene mellem hulstenene udstøbes beton for den egentlige dækkonstruktion. Man kan også anbringe sådanne hullegemer mellem præfabrikerede bæreelementer på passende udkragninger eller flanger på bæreelementerne og derefter udstøbe beton i hulrummene mellem de præfabrikerede elementer og hullegemerne .The use of hollow bodies or bricks of bricks or concrete is known for the manufacture of tire structures. These elements are laid out on a formwork, whereupon concrete is cast for the actual tire construction in the cavities between the hollows. It is also possible to place such hollow bodies between prefabricated supporting elements on suitable projections or flanges on the supporting elements and then cast concrete into the voids between the prefabricated elements and the hollow bodies.

2 141342 I alle disse tilfælde er det, fordi hullegemer kun kan fremstilles med ringe bredde, ikke muligt at vælge større ribbeafstande. For at afhjælpe denne mangel har man foreslået at slå bro over gabet mellem to ribber ved hjælp af to hulsten. Dette kræver, at der træffes særlige foranstaltninger. Eksempelvis kan der på forskallingen lægges to spejlsymmetriske hulsten ved siden af hinanden, sådan at de i den færdige dækkonstruktion støtter som hvælvinger mod stålbetonribberne, eller man kan ophænge to spejlsymmetriske tegllegemer på passende fremspring eller flanger på bæreelementerne, der er udlagt i passende afstand, således at legemerne også har støtter hvælvet mellem elementerne. På grund af den ringe formnøjagtighed for sådanne teglhullegemer forekommer imidlertid den ulempe, at der i stødfugen mellem legemerne kun forekommer punktvis berøring og dermed for store belastninger.In all these cases, because the hollow bodies can only be made with a small width, it is not possible to choose larger rib spacings. To remedy this deficiency, it has been proposed to bridge the gap between two ribs using two hollows. This requires special measures to be taken. For example, two mirror-symmetrical hollows may be laid next to each other on the formwork so as to support the finished deck structure as vaults against the steel concrete ribs, or two mirror-symmetrical tile bodies may be hung on suitable projections or flanges on the supporting elements laid at a suitable distance. that the bodies also support the vault between the elements. However, due to the poor shape accuracy of such brick cavity bodies, the disadvantage is that in the butt joint between the bodies there is only point-wise contact and thus excessive loads.

Til i hvert fald delvis undgåelse af denne ulempe er det kendt inden indbygning i dækkonstruktionen at forbinde de to hulsten og at udforme de to mod hinanden liggende flader med udskæringer og noter, således at der afgrænses et hulrum, der fyldes med beton.For at least partial avoidance of this disadvantage, it is known to incorporate the two hollows before incorporation into the tire structure and to design the two opposite surfaces with cuts and grooves, so that a cavity filled with concrete is defined.

Bortset fra vanskeligheden ved fremstillingen har disse kendte bærende elementer også den ulempe, at vægten er stor.Apart from the difficulty of manufacture, these known supporting elements also have the disadvantage that the weight is large.

Dette er uheldigt såvel under transport som ved oplægning af elementerne.This is unfortunate both during transport and when laying the elements.

Der kendes også bærende elementer, hvor formsten er •kombineret med en forspændt drager, hvor formstenen i det væsentlige kim omhyller dragerens trækzone. Sådanne elementer er på grund af deres ringe højde forholdsvis lette og derved lette at transportere og udlægge, men de har den store ulempe, at der i den færdige bjælke optræder betragtelige trækspændinger i fugen mellem det færdige element og den på fabrikations- eller brugsstedet yderligere anbragte beton. En væsentlig ulempe er det også, at de forspændte elementer ved montagen skal understøttes, fordi deres bæreevne på grund af den ringe statiske højde ikke er tilstrækkelig til at optage montagebelastningen eller endog egenvægten.Carrying elements are also known in which the moldstone is • combined with a prestressed carrier, the moldstone substantially germinating the carrier's drawing zone. Due to their low height, such elements are relatively light and thereby easy to transport and lay, but they have the great disadvantage that considerable tensile stresses in the joint between the finished element and the place of manufacture or use are present in the finished beam. concrete. A major disadvantage is also that the biased elements at the mounting must be supported, because their bearing capacity due to the low static height is not sufficient to absorb the mounting load or even the weight.

Alle de kendte elementer har endvidere den ulempe, at de er forholdsvis dårligt varmeisolerende, således at der må træffes særlige isoleringsforanstaltninger. Endvidere er 3 141342 varmeledningsegenskabeme for dragerne og stenene forskellige.Furthermore, all the known elements have the disadvantage that they are relatively poorly heat insulating, so that special insulation measures must be taken. Furthermore, the thermal conductivity properties of the dragons and stones are different.

Dette kan i visse tilfælde medføre kondensvandsdannelse ved undersiden af loftet. Det er derfor nødvendigt at forsyne undersiden med et ensartet isoleringslag, hvilket naturligvis' medfører forøgede omkostninger.This can in some cases cause condensation to form at the underside of the ceiling. It is therefore necessary to provide the underside with a uniform insulating layer, which of course will incur increased costs.

Formålet med opfindelsen er at anvise et præfabrikeret bærende element, hvor de nævnte ulemper er undgået, især således at en lofts- eller tagkonstruktion med en homogen, ensartet varmeisolerende underside kan fremstilles uden brug af afstivninger.The object of the invention is to provide a prefabricated supporting element, whereby said disadvantages are avoided, especially so that a ceiling or roof structure with a homogeneous, uniform heat insulating underside can be manufactured without the use of braces.

Dette opnås ifølge opfindelsen ved den i kravet anviste konstruktion.This is achieved according to the invention by the construction according to the claim.

På grund af det lette byggemateriales ringe vægt kan det bjælkeformede legeme have en forholdsvis stor bredde, således at lofts- eller tagkonstruktionen kan opbygges hurtigt og let uden brug af afstivninger. Da de bjælkeformede legemer lægges tæt ved siden af hinanden, opnås en upåklagelig gennemgående underside.Due to the light weight of the lightweight building material, the beam-shaped body can have a relatively large width, so that the ceiling or roof structure can be built quickly and easily without the use of stiffeners. As the beam-shaped bodies are placed close to each other, an impeccable through-side is obtained.

Fordelagtigt er sidefladerne på det bjælkeformede legeme profilerede, således at en sideflade på et legeme passer ind i isidefladen på et nabolegeme, hvorved der opnås et godt forband mellem naboelementerne.Advantageously, the side surfaces of the beam-shaped body are profiled so that a side surface of a body fits into the ice side surface of a neighboring body, thereby obtaining a good bond between the neighboring elements.

De bjælkeformede legemer kan eksempelvis have savtakkede langsgående ribber, eller den ene sideflade kan have mindet en not og den anden sideflade en heri passende fjer.The beam-shaped bodies may, for example, have saw-cut longitudinal ribs, or one side surface may have a groove and the other side surface a suitable spring.

Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor fig. 1 viser et snit gennem et element ifølge opfindelsen, fig. 2 og 3 tilsvarende snit gennem andre udførelsesformer, og fig. 4 og 5 snit gennem to loftskonstruktioner, hvori indgår elementer ifølge opfindelsen.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail in connection with the drawing, in which: FIG. 1 shows a section through an element according to the invention; FIG. 2 and 3 show similar sections through other embodiments; and FIGS. 4 and 5 are sections through two ceiling structures incorporating elements according to the invention.

Det i fig. 1 viste element omfatter en ståltrådskonstruktion 1, hvis trækzone er anbragt i en betondrager 2. Denne betondrager er indstøbt i et bjælkeformet legeme 3 af skumbeton.The FIG. 1 comprises a steel wire structure 1, the tensile zone of which is arranged in a concrete carrier 2. This concrete carrier is embedded in a beam-shaped body 3 of foam concrete.

Den øverste del af legemet 3 virker ved fremstilling af et dæk som betonfortrængningslegeme, hvorved uønskede betonvedhæft-ninger i den neutrale zone tindgås. Udformningen som betonfortrængningslegeme kan også være sådan, at der på oversiden af legemet 3 findes tværribber, udskæringer eller skråribber.The upper part of the body 3 acts in the manufacture of a tire as a concrete displacement body, thereby eliminating unwanted concrete adhesions in the neutral zone. The design as a concrete displacement body may also be such that on the upper surface of the body 3 there are transverse ribs, cuts or oblique ribs.

141342 4141342 4

Den nederste del af legemet 3 giver en isolerende, ensartet loftsflade.The lower part of the body 3 provides an insulating, uniform ceiling surface.

I stedet for ståltrådskonstruktionen 1 med den trækzonen omgivende betondrager 2 kan benyttes enhver anden kendt drager.Instead of the steel wire structure 1 with the concrete zone 2 surrounding the tensile zone, any other known carrier can be used.

Således er i fig. 2 vist en T-formet betondrager 4 med en langsgående armering i trækzonen, hvorved dragerens 4 lodrette krop 6 rager ud af det bjælkeformede legeme 3. Endvidere har ved denne udførelsesform legemets 3 ene sideflade en not 7* medens den anden sideflade har en ribbe eller fjer 8, der kan bringes i indgreb med noten 7 på et nabolegeme.Thus, in FIG. 2 shows a T-shaped concrete support 4 with a longitudinal reinforcement in the pull zone, whereby the vertical body 6 of the support 4 protrudes from the beam-shaped body 3. Furthermore, in this embodiment one side surface of the body 3 has a groove 7 * while the other side surface has a rib or feathers 8 which can be engaged with the groove 7 on a neighboring body.

Fig. 3 viser en udførelsesform med en betondrager 9, der har såvel langsgående armering 5,10,11 som tværarmering 12. Også ved denne udførelsesform er den i trækzonen værende del af betondrageren 9 omhyllet af et bjælkeformet legeme 3. Legemets 3 sideflader har her savtakformede langsgående ribber 13» således at sammenstødende sideflader på to nabolegemer passer ind i hinanden.FIG. 3 shows an embodiment with a concrete support 9 having both longitudinal reinforcement 5,10,11 and cross reinforcement 12. Also in this embodiment, the part of the concrete support 9 which is in the tensile zone is enclosed by a beam-shaped body 3. The lateral surfaces of the body 3 have saw-shaped longitudinal ribs 13 'so that adjacent side surfaces of two neighboring bodies fit together.

Fig. 4 viser et snit gennem en del af en loft^konstruktir>n med elementer ifølge opfindelsen. Elementerne svarer i det væsentlige til det i fig. 2 viste, men undersiden af de bjælkeformede legemer er her hvælvet.FIG. 4 shows a section through part of a ceiling structure with elements according to the invention. The elements correspond substantially to that of FIG. 2, but the underside of the beam-shaped bodies is arched here.

Opbygningen af en loftskonstruktion med elementer ifølge opfindelsen er yderst enkel. De enkelte elementer lægges, uden brug af støttekonstruktioner, ved siden af hinanden på de forhåndenværende mure. Som vist i fig. 4 kan der over elementerne udstøbes et betonlag 15, der omhyller de udragende dele 6 af betondragerne 4, således at betonlaget 15 sammenbinder disse.The construction of a ceiling structure with elements according to the invention is extremely simple. The individual elements are laid next to each other on the existing walls, without the use of supporting structures. As shown in FIG. 4, a concrete layer 15 can be cast over the elements, which encloses the projecting parts 6 of the concrete supports 4, so that the concrete layer 15 joins them.

Det er ikke nødvendigt, at dele af betondragerne rager uden for de bjælkeformede legemer 3. Fig. 5 viser således et snit gennem en del af en loftskonstruktion, hvor elementernes betondragere 4 er fuldstændigt indstøbt i de bjælkeformede legemer 3 af skumbeton. Ved den i fig. 5 viste udførelsesform er elementernes sideflader savtakkede som i fig. 3.Det i fig. 4 viste betonlag er udeladt ved den i fig. 5 viste udførelsesform, der til gengæld har et isolerende lag 16, eksempelvis et pudslag på undersiden.It is not necessary that parts of the concrete supports extend outside the beam-shaped bodies 3. Figs. 5 thus shows a section through a part of a ceiling structure where the concrete supports 4 of the elements are completely embedded in the beam-shaped bodies 3 of foam concrete. In the embodiment shown in FIG. 5, the side surfaces of the elements are sawed as in FIG. 3. The FIG. 4 is omitted from the concrete layer shown in FIG. 5, which in turn has an insulating layer 16, for example a plaster layer on the underside.
