Description
1"? 50 'bf '63 47 58 49 diverse intryckningar eller utbuktningar i plåten anses gripa tag i betongens undersida. Denna metod och används ej i vägbroar. farbaneplattan med armering som momentstyvt homogena betongbalkar. Ett annat vanligt sätt är att använda sig av stålbalkar, t ex I-balkar, där överflänsen ansluter till en underliggande flexibel livplåt. Den förra konstruktionen är gppfinningens andamal och viktigaste kännetecken Ändamålet med uppfinningen är att Uppfinningen utgor ett nytt satt att balk och farbaneplatta säkerställs i denna skjuvarmering utan Samverkan mellan konstruktion ej med studs, spjälkarmering och med en speciell typ av skruvförband, som först överför skjuvkrafterna från balkarna till de på dessa utlagda stälkassetterna, som sträcker sig från balk till balk och dessutom kragar ut utanför dessa. Kassetterna kan sedan p g a stor egen styvhet i farbaneplattans plan fördela skjuvkrafterna på en större bredd av farbaneplattan. Till skjuvförbandet mellan kassett och balk används en grov gängpressande specialskruv med härdad spets. Tillsammans med en distansplåt, som samtidigt utgör kvarsittande mall för skruvgruppen, alternativt andra distanselement, uppnås en extremt hög utmattningshållfasthet i förbandet, vertikalt uppåt sig sträckande kantflänsar, därefter snett inåt, uppåt och företrädesvis symmetriskt, sig sträckande överflänsar, som avslutas med vertikalt sig uppåtsträckande delar med uppåt öppna urtag för armeringsjärn. De snett inåt och uppåt riktade flänsarna utgör mothåll för den gigg som används för borrning genom såväl kassett somm balkfläns. Den plana underflänsen betongen. Spalten mellan kassettens undersida och balken kan tätas med lim eller fogmassa, ytbeläggning. 1 "? 50 'bf '63 47 58 49 various indentations or bulges in the plate are considered to grip the underside of the concrete. This method and is not used in road bridges. The siding plate with reinforcement as momentarily rigidly homogeneous concrete beams. Another common way is to use steel beams The former construction is the spirit and most important feature of the invention. , slatted reinforcement and with a special type of screw joint, which first transfers the shear forces from the beams to those on these laid cassette cassettes, which extend from beam to beam and also collars out beyond these. The cassettes can then, due to their own rigidity in the plane plate plane, distribute the shear forces on a larger width of the tread plate.To the shear connection between cassette and b alk uses a coarse thread-pressing special screw with a hardened tip. Together with a spacer plate, which at the same time constitutes a retaining template for the screw group, alternatively other spacer elements, an extremely high fatigue strength is achieved in the joint, vertically upwardly extending edge flanges, then obliquely inwards, upwards and preferably symmetrically, extending upflanges terminating vertically. parts with upwardly open recesses for rebar. The obliquely inwardly and upwardly directed flanges form an abutment for the gig used for drilling through both the cassette and the beam flange. The flat lower flange the concrete. The gap between the underside of the cassette and the beam can be sealed with glue or sealant, surface coating.
IQ ZO Zl ll ZÖ s 501 sas Kraftöverföringen inom farbaneplattan förbättras med uppfinningen på följande sätt. Betongens bristfälliga förmåga- att uppta tvärkrafter ersätts av den sammantagna bärförmågan hos kassettens kantflänsar, snett uppåt sig sträckande överflänsar och uppåt sig sträckande avslutande delar. Farbaneplattan kan därigenom göras tunnare än normalt. Samverkanskrafter mellan stål och betong överförs effektivt genom mekanisk anliggning mellan urtagens vertikala kanter och armeringsjärnen.IQ ZO Zl ll ZÖ s 501 sas The power transmission within the tread plate is improved with the invention in the following manner. The concrete's inadequate ability to absorb transverse forces is replaced by the total load-bearing capacity of the edge flanges of the cassette, obliquely upwardly extending upper flanges and upwardly extending terminating parts. The tread plate can thereby be made thinner than normal. Interaction forces between steel and concrete are efficiently transmitted through mechanical abutment between the vertical edges of the recesses and the reinforcing bars.
Kassettens utsträckta form i höjdled gör att krafterna överförs nära den nivå i farbaneplattan där betongtryckresultanten ligger.The extended height of the cassette means that the forces are transmitted close to the level in the tread plate where the concrete pressure resultant is located.
Kassettens godstjocklek är sä stor att all dragarmering i plattans underkänt i brons tvärriktning ersätts med kassettens underfläns. Genom att kassettens underfläns kan ta upp hela dragkraften i tvärsnittet uppnås maximal inre hävarm och maximal momentupptagande förmåga. Även vid moment med omvänt tecken uppnås maximal momentupptagande förmåga, eftersom kassettens underfläns ensam kan ta upp tryckkraften av momentet. Kassettens snett inåt och uppåt riktade flänsar tillsammans med den reducerade armeringsmängden möjliggör en säkrare betonggjutning och ger en farbaneplatta med högre kvalitet. Farbaneplattan får alltså en mycket god förmåga att uppta höga koncentrerade punktlaster genom den extremt goda förmågan att vid en given plattjocklek uppta såväl moment som tvärkraft.The wall thickness of the cassette is so large that all tensile reinforcement in the failure of the plate in the transverse direction of the bronze is replaced by the lower flange of the cassette. Because the cassette's lower flange can absorb the entire tensile force in the cross section, maximum internal lever and maximum torque-absorbing ability are achieved. Even with torque with the reverse sign, maximum torque-absorbing ability is achieved, since the lower flange of the cassette alone can absorb the compressive force of the torque. The cassette's obliquely inward and upwardly directed flanges together with the reduced amount of reinforcement enable a safer concrete casting and provide a tread plate with higher quality. The siding plate thus has a very good ability to absorb high concentrated point loads through the extremely good ability to absorb both moment and transverse force at a given plate thickness.
Kantbalkens form samt det förhållandet att betong och skruvar i farbaneplattan skyddas av den täta undersidan och det isolerande tätskiktet på ovansidan gör att betong, skruvar och armering får ett på alla sidor gott skydd mot tösalter, urlakning och karbonatisering.The shape of the edge beam and the fact that concrete and screws in the tread plate are protected by the dense underside and the insulating sealing layer on the upper side means that concrete, screws and reinforcement get good protection against thawing salts, leaching and carbonation on all sides.
Används betongfyllda balkar med tvá närliggande livplåtar uppnås betongbalkbrons fördelar ur temperaturutjämningssynpunkt, vilket ofta ger enklare och billigare landfästen, lager och övergàngsanordningar. Samtidigt fås, med eller utan betongfyllnad, en konstruktion med god vridstyvhet och stabilitet samt stälbalkbrons fördelar med låg vikt och hög förtillverkningsgrad. Enligt uppfinningen ger det speciella skruvförbandet tillsammans med kassettens dimensioner och form full samverkan mellan balk och farbaneplatta i brons längsled samtidigt som infästningen kan utformas så flexibel att den kan uppta horisontalkrafter och moment från balkarna utan att skadliga tvångskrafter uppträder i kassetter och skruvar.If concrete-filled beams with two adjacent lifeplates are used, the advantages of the concrete beam bronze are achieved from a temperature equalization point of view, which often provides simpler and cheaper land anchors, bearings and transition devices. At the same time, with or without concrete filling, a construction with good torsional rigidity and stability is obtained, as well as the advantages of the steel beam bronze with low weight and high degree of prefabrication. According to the invention, the special screw connection together with the dimensions and shape of the cassette provides full cooperation between beam and tread plate in the bronze longitudinal direction while the attachment can be designed so flexible that it can absorb horizontal forces and moments from the beams without harmful coercive forces appearing in cassettes and screws.

Beskrivning av utföringsexempel barbalkar(3) gjuts en brofarbana(1) av betong. Betongen(l7) gjuts på tvärs balkarna(3) skruvade stàlkassetter(2). De från balkarna utkragande kassetterna(2) avslutas med en kantbalk (fig 8). Pâ farbaneplattans ovansida finns ett isolerande symmetriskt, sig sträckande överflänsar(10), som avslutas med vertikalt sig uppàtsträckande delar(11) med uppåt öppna urtag(l2) för armeringsjärn(13).Description of exemplary embodiments Bar beams (3) cast a bridge bridge track (1) of concrete. The concrete (l7) is cast on steel cassettes (2) screwed across the beams (3). The cassettes (2) projecting from the beams are finished with an edge beam (Fig. 8). On the upper side of the tread plate there is an insulating symmetrical, extending upper flanges (10), which terminate with vertically extending parts (11) with upwardly open recesses (l2) for rebar (13).
När ett antal kassetter(2) har lagts ut pâ bärbalkarna(3) skruvas dessa fast med skruvförbandet enligt figur 2. För att flänsar(9) under montaget används ett specialverktyg figur 4(14). Skruvhál borras samtidigt genom kassetternas(2) underf1äns(8) och bärbalkarnas(3) överfläns enligt figur 5, 6, och 7. Därefter skruvas grova gängpressande skruvar(4) med härdad spets(5) med hjälp av luftdrivna eller elektriska skruvdragare genom kassett och överfläns. Mellan skruvskallen 5 501 sas och kassettens underf1äns(8) monteras ett distanselement, på bilden visat som en plåtma1l(6) som har till uppgift att exakt placera skruvarna(4) så att rätt flexibilitet uppnås.When a number of cassettes (2) have been laid out on the support beams (3), these are screwed on with the screw connection according to figure 2. For flanges (9) during assembly, a special tool figure 4 (14) is used. Screw holes are drilled simultaneously through the lower flange (8) of the cassettes (2) and the upper flange of the support beams (3) according to Figures 5, 6, and 7. Then coarse threaded screws (4) with hardened tip (5) are screwed through cassette by means of air-driven or electric screwdrivers and upper flange. A spacer element is mounted between the screw head 5501 and the lower flange (8) of the cassette, shown in the picture as a sheet metal grinder (6) which has the task of accurately placing the screws (4) so that the correct flexibility is achieved.
Kassetten(2) fördelar ut krafterna på brons bredd och överför med anliggningstryck(fig 7) krafterna till farbaneplattan(fig 10). Alternativa distanselement(7) kan användas. Kassettens undersida och bärbalkens översida kan tätas med lim eller fogmassa(fig 14).The cassette (2) distributes the forces on the width of the bronze and transfers the forces to the tread plate (Fig. 10) with abutment pressure (Fig. 7). Alternative spacers (7) can be used. The underside of the cassette and the upper side of the support beam can be sealed with glue or sealant (fig. 14).
När kassetterna(2) är monterade på bärbalkarna(3) och kantbalkarna är monterade på kassetterna med självgängande skruv(fig 8) monteras armeringen i kassetternas(2) urstansade hack(12). Armeringens(13) uppgift är att enligt figur 9 dels säkerställa samverkan mellan betongen(17) och stàlkassetterna(2), dels utgöra armering(13) i brons längsled.When the cassettes (2) are mounted on the support beams (3) and the edge beams are mounted on the cassettes with self-tapping screws (Fig. 8), the reinforcement is mounted in the punched notches (12) of the cassettes (2). The task of the reinforcement (13) is to, according to Figure 9, partly ensure cooperation between the concrete (17) and the steel cassettes (2), and partly constitute reinforcement (13) in the longitudinal direction of the bronze.
När kassetterna(2) är monterade och armeringen(13) är utförd gjuts brofarbanan med betong(17). Slutligen pàförs ett isolerande tätskikt(19) som kan vara slitbetong eller asfalt.When the cassettes (2) are mounted and the reinforcement (13) is done, the bridge deck is cast with concrete (17). Finally, an insulating waterproofing layer (19) is applied, which can be abrasive concrete or asphalt.
Några icke begränsande förslag vad gäller material och dimensioner skall även här nämnas. Kassetten(2) utförs i stålplàt med en godstjocklek på 4-7 mm. Kassettens(2) totala höjd kan vara 110-130 mm, höjden från underflänsen till den symmetriskt inåtgående flänsen(10) är 80-100 mm och kassettens totala bredd uppgår till 400-450 mm. De urstansade hacken(12) på kassettens övre avslutande fläns har ett inbördes avstånd på 50 mm. De urstansade hackens kanter är vertikala och horisontella. Skruven i hàllfasthetsklass 10.9 utföres med M- gänga 12-16 mm.Some non-limiting proposals regarding materials and dimensions should also be mentioned here. The cassette (2) is made of sheet steel with a wall thickness of 4-7 mm. The total height of the cassette (2) can be 110-130 mm, the height from the lower flange to the symmetrically inwardly extending flange (10) is 80-100 mm and the total width of the cassette is 400-450 mm. The punched notches (12) on the upper end flange of the cassette have a mutual distance of 50 mm. The edges of the punched notches are vertical and horizontal. The screw in strength class 10.9 is made with M-thread 12-16 mm.
Samverkanstekniken med det beskrivna skruvförbandet och stàkassetter monterade på bärbalkar kan även användas till liknande konstruktioner, exempelvis parkeringsdäck och bjâlklag där tunga truckar och lastfordon används.The interaction technology with the described screw connection and standing cassettes mounted on supporting beams can also be used for similar constructions, for example parking decks and joists where heavy trucks and lorries are used.
