Opfindelsen angår en dragerforskalling med forskallingsplader for dragerens tilnærmelsesvis lodrette sideflader og med en nederste til fastholdelse af et tilnærmelsesvis vandret forskallingsdæk for dragerbunden tjenende tværdrager, der med sine ender rager ud forbi 5 de lodrette forskallingsplader, og i hvert af sine udragende endeområder har et opadragende afstivningselement, der strækker sig ind i forskallingspladernes område, og af hvilke i det mindste det ene afstivningselement kan forskydes på tværdrageren i dennes længderetning.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a carrier formwork having formwork plates for the substantially vertical side surfaces of the carrier and with a lower for retaining an approximately horizontal formwork deck for carrier-based transverse supports extending at its ends beyond the vertical formwork plates, and in each of its protruding end regions. extending into the area of the formwork plates and of which at least one stiffening element can be displaced on the transverse carrier in its longitudinal direction.

Fra FR-A-742.281 kendes en dragerforskalling af denne art. Denne • kendte dragerforskalling har den ulempe, at der skal anvendes komplicerede afstivningselementer til afstivning af de lodrette forskallingsplader, der blot består af træplader, og at der desuden 15 skal anvendes to oven over hinanden beliggende tværdragere, af hvilke den øverste understøtter forskallingsdækket, medens den nederste tjener til at bære afstivningselementerne for de lodrette forskallingsplader. Afstivningselementerne er anbragte parvis, for at den øverste og den nederste tværdrager skal kunne gribe ind 20 mellem disse. Endvidere skal disse afstivningselementer være forsynede med udragende lasker med huller for søm til forbindelse af træpladerne med afstivningselementerne.From FR-A-742,281 a kite formwork of this kind is known. This known carrier formwork has the disadvantage of having to use complicated stiffening elements for stiffening the vertical formwork plates consisting only of wooden boards, and in addition that two superimposed transverse supports, of which the upper one supports the formwork deck, must be used, while the lower serves to support the stiffening elements for the vertical formwork plates. The stiffening elements are arranged in pairs so that the upper and lower transverse supports can engage 20 between them. Furthermore, these stiffening elements must be provided with protruding holes with holes for nails to connect the wooden boards with the stiffening elements.

Ifølge en i fig. 3 i det nævnte FR-A-742.281 vist udførelsesform er 25 det ganske vist muligt at nøjes med en enkelt vandret tværdrager, men til gengæld nødvendiggør denne udførelsesform en kompliceret indstillings- og holdeanordning mellem det ene af de på tværdrageren anbragte afstivningselementer og en i forhold til dette forskydelig anslagsplade til fastgørelse på forskall ingspladerne.According to one of FIG. 3 of said embodiment shown in FR-A-742.281, it is possible to settle for a single horizontal transverse carrier, but on the other hand this embodiment requires a complicated adjustment and holding device between one of the stiffening elements arranged on the transverse carrier and a relative to this slidable impact plate for attachment to the formwork plates.

Man har i mange år så vidt muligt anvendt forskallingsplader med kantribber i stedet for forskallingsplader i form af simple træpla der. Fra DE-A-3 403 148 kendes en dragerforskalling, ved hvilken der til forskallingen for dragerens tilnærmelsesvis lodrette sideflader 35 anvendes forskallingsplader, der ved deres kanter har på støbefladen tilnærmelsesvis vinkelrette kantribber. Som forskallingsdæk for undersiden af drageren anvendes ligeledes med kantribber forsynede forskallingsplader, der ved hjælp af hjørneskinner skal forbindes med de lodrette forskallingsplader. Dette betyder, at disse nedersteFor many years, as far as possible, formwork boards with edge strips have been used instead of formwork boards in the form of simple wooden boards. From DE-A-3 403 148 there is known a carrier formwork, in which the formwork is used for the formwork for the approximately vertical side surfaces of the carrier 35, formwork plates having their edges on the molding surface at approximately perpendicular edges. The formwork deck for the underside of the carrier is also used with edge strips formwork boards which must be connected to the vertical formwork boards by means of corner rails. This means that these are the bottom

2 forskali ingsplader bestemmer bredden af drageren. Endvidere danner kantribberne fremspring på den bort fra støbefladen vendende side af forskallingspladerne, således at de fra det nævnte FR-A-742.281 kendte afstivningsorganer ikke uden videre kan bringes i anlæg mod 5 et af sådanne forskallingsplader dannet forskallingsdæk.2 grinding plates determine the width of the carrier. Furthermore, the edge strips form projections on the side facing away from the molding plate so that the stiffening means known from the aforementioned FR-A-742,281 cannot be brought into contact with any formwork deck formed by such formulation plates.

Formålet med opfindelsen er derfor at tilvejebringe en dragerforskalling af den indledningsvis nævnte art, med hvilken der med ens forskallingselementer, der i det mindste ved deres kante har vin-10 kel ret på støbefladen stående kantribber med fastgørelsessteder, kan fremstilles forskallinger for forskelligt brede dragere, samtidig med at de fordele bibeholdes, som opnås ved anvendelsen af de kendte 1 forskali ingsplader med kantribber. D.v.s. at disse forskallingsplader, der i forvejen føres på lager og også anvendes til det øvrige 15 støbearbejde, også skal kunne anvendes til forskallinger til støbning af dragere, således at dyrt tømrerarbejde undgås ved forskalling af dragere. Endvidere skal disse lodrette forskali ingsplader med kantribber på trods af kantribberne kunne afstives ved hjælp af afsti vn i ngsorganerne.The object of the invention is therefore to provide a carrier formwork of the type mentioned in the introduction, with which, with even formwork elements, which are at least at their edges perpendicular to the casting surface, with fastening locations, formulations can be made for different wide carriers. while retaining the advantages obtained by the use of the prior art 1 grating strips. I.e. that these formwork plates, which are already in stock and also used for the other 15 casting work, should also be applicable to formwork for molding of carriers, so that expensive carpentry work is avoided by formwork of carriers. In addition, despite these edge ribs, these vertical formwork plates with edge strips must be able to be stiffened by means of stiffeners in the cutting members.

Denne opgave løses ifølge opfindelsen ved, at hvert afstivningsorgan er udformet som en flange med mindst ét fastgørelsessted til forbindelse med dertil svarende forbindelsessteder på tilnærmelsesvis vinkelret på forskallingsdækket stående kantribber på forskallings-25 pladerne, og at hver flange ved den mod den anden flange vendende side og umiddelbart oven over tværdrageren, der forbinder flangerne med hinanden, har en ved kanten åben udsparing til optagelse af den på tværs forløbende nederste kantribbe af de lodrette forskallings-plader på en sådan måde, at flangerne når hen til nær bagsiden af 30 det af forskallingspladerne med kantribberne dannede forskal1 ings-dæk.This task is solved according to the invention in that each stiffening member is formed as a flange with at least one attachment point for connection with corresponding connection points at approximately perpendicular to the formwork deck on the formwork plates and that each flange at the opposite flange faces and immediately above the transverse carrier connecting the flanges to each other has an open-cut recess for receiving the transverse lower edge rib of the vertical formwork plates in such a way that the flanges reach near the rear of that of the formwork plates. with the edge ribs, formwork tires formed.

Ved hjælp af disse ejendommeligheder i kombination opnås, at afstivningselementerne, selv når de lodrette forskallingsplader har 35 kantribber, på sikker og enkel måde kan fastgøres til de lodrette forskallingsplader og understøtte disse. Det er en særlig fordel, at flangerne trods forskallingspladernes nederste kantribbe nemt kan bringes i indgreb og forbindes med fastgørelsesstedet på en lodret kant- eller afstivningsribbe på det af forskallingspladerne dannedeBy means of these peculiarities in combination, it is achieved that the stiffening elements, even when the vertical formwork plates have 35 edge strips, can be securely and easily attached to the vertical formwork plates and support them. It is a particular advantage that, despite the lower edge ribs of the formwork plates, the flanges can be easily engaged and connected to the attachment point on a vertical edge or stiffening rib formed by the formwork plates.

3 forskallingsdæk. Dermed er nødvendigheden af en fastgørelse af forskallingspladerne til afstivningselementerne ved hjælp af søm elimineret. Samtidig er den fordel bibeholdt, at bredden af dragerforskallingen på enkel måde kan tilpasses efter behov.3 formwork tires. Thereby, the necessity of attaching the formwork plates to the stiffening elements by stitching is eliminated. At the same time, the advantage is maintained that the width of the kite formwork can be easily adjusted as needed.

5 I det mindste, den ene flange kan fordelagtigt have to oven over hinanden anbragte fastgørelsessteder, fortrinsvis fastgørelseshuller til anbringelse på en lodret kant- eller afstivningsribbe på en forskallingsplade i dragerforskallingen. Herved opnås der også i 10 dette område en fast og sikker forbindelse med tværdrageren og det vandrette forskallingsdæk, der understøttes på denne.At least, one flange may advantageously have two superposed mounting locations, preferably attachment holes for mounting on a vertical edge or stiffening rib on a formwork plate in the carrier formwork. This also provides in this area a firm and secure connection with the transverse carrier and the horizontal formwork deck supported on it.

Fastgørelsesstederne kan særligt fordelagtigt være nøglehulformede huller, i hvilke bolte med tværstifter kan indsættes og drejes til 15 låsning. Sådanne fastgørelsesbolte, som kendes fra DE-A-21 37 505 har vist sig at være velegnede til fastgørelse af forskallingsplader med kantribber til hinanden og til fastgørelse af tilbehørsdele på disse forskallingsplader. Ved udformningen af fastgørelsesstederne som nøglehulformede huller, der passer til boltene, kan disse bolte 20 også anvendes ved dragerforskallingen ifølge opfindelsen.The attachment points can be particularly advantageous for keyhole holes in which bolts with cross pins can be inserted and turned for locking. Such fastening bolts known from DE-A-21 37 505 have been found to be suitable for attaching formwork plates with edge strips to each other and for attaching accessory parts to these formwork plates. In designing the attachment points as keyhole holes to fit the bolts, these bolts 20 may also be used in the carrier formwork according to the invention.

Til opnåelse af en enkel konstruktion kan flangerne bestå af fladt materiale, såsom plademateriale, fladjern, profiljern eller lignende og i brugssti 11 ingen ligge an med et kantområde af deres flade side 25 mod den flade side af kantribben eller en afstivningsribbe på forskallingspladen, hvorunder flangernes fastgørelseshuller er bragt til dækning med fastgørelseshullerne i denne kant- eller afstivningsribbe. Ved en passende materialetykkelse af disse flanger, der tilnærmelsesvis svarer til tykkelsen af forskallingspladernes 30 ribber, kan de til fastgørelse af sådanne forskallingsplader til hinanden bestemte bolte anvendes uden særlig tilpasning.For a simple construction, the flanges may consist of flat material, such as sheet metal, flat iron, profile iron or the like and in the use path 11, none abut an edge area of their flat side 25 against the flat side of the edge rib or a stiffening rib on the formwork plate, under which the flanges mounting holes are covered with the mounting holes in this edge or stiffening rib. At a suitable material thickness of these flanges approximately equal to the thickness of the ribs of the formwork plates 30, they can be used for attaching such formwork plates to one another without special adjustment.

En udførelsesform af opfindelsen er ejendommelig ved, at tværdrageren i brugsstillingen er anbragt på højkant, d.v.s. set i tværsnit 35 med sin med fastgørelsesstederne forsynede flade side tilnærmelsesvis lodret, og at flangerne ligger an mod denne flade side. Derved opnås den fordel, at den med fastgørelsesstederne udformede flig af tværdrageren selv danner afstivningen og fordelagtigt kan overføre kræfterne fra flangerne.An embodiment of the invention is peculiar in that the transverse carrier in the position of use is placed upright, i.e. seen in cross section 35, with its flat side provided with the fastening points approximately vertical, and that the flanges abut against this flat side. Thereby, the advantage is obtained that the tab formed by the transverse carrier forms the brace itself and can advantageously transfer the forces from the flanges.

Det er her fordelagtigt, dersom tværdrageren har mindst én afstivningsflig på sin flade side, fortrinsvis den bort fra indgrebsstedet med flangen vendende side. Derved forøges stabiliteten også i tilnærmelsesvis vandret retning.It is advantageous here if the transverse carrier has at least one stiffening tab on its flat side, preferably the one away from the point of engagement with the flange facing side. Thereby, the stability is also increased in an approximately horizontal direction.

En særlig enkel fremstilling opnås, dersom tværdrageren er udformet som en profilskinne, f.eks. som en vinkel- eller U-skinne, hvis flig eller flige danner afstivningsfligen eller -fligene.A particularly simple preparation is obtained if the transverse carrier is designed as a profile rail, e.g. as an angular or U-rail whose tab or tab forms the stiffening tab or tabs.

10 Ifølge en anden udførelsesform kan tværdrageren til forstærkning af afstivningen neden under en vandret, flad skinne have to vinkel -skinner, hvis lodrette flige danner afstivningsflige. Vinkelskinnerne kan ligge med deres lodrette flige vendende mod hinanden, og eventuelt kan der til yderligere forstærkning være fastgjort for-15 trinsvis indsvejst et fladjern mellem disse lodrette vinkelflige.According to another embodiment, the transverse carrier for reinforcing the stiffening beneath a horizontal flat rail may have two angular rails whose vertical tabs form stiffening tabs. The angle rails may lie with their vertical tabs facing each other, and optionally a further flat iron may be welded between these vertical angular tabs for further reinforcement.

Ifølge en fordelagtig udførelsesform af dragerforskali ingen ifølge opfindelsen er endeområdet af tværdrageren forlænget ud forbi flangens indgrebssted med drageren og har mindst ét fastgørelsessted 20 for den ene ende af en skråstiver, der ved sin anden ende indgriber med den lodrette forskallingsplade. En sådan udformning er især fordelagtig til støbning af dragere med stort tværsnit, hvor der ved forskallingen og støbningen optræder store kræfter.According to an advantageous embodiment of carrier formwork according to the invention, the end region of the transverse carrier is extended beyond the engagement point of the flange with the carrier and has at least one attachment point 20 for one end of an inclined strut which engages at its other end with the vertical formwork plate. Such a design is particularly advantageous for molding of large cross-sectional carriers, where large forces occur during formwork and casting.

25 Enden eller enderne af skråstiveren kan fordelagtigt være udformede med lasker og være forsynede med mindst ét hul, der passer til fastgørelseshullerne i tværdrageren og/eller i forskallingspladens ribber. Derved lettes monteringen. Skråstiverens effektive længde kan være variabel ved hjælp af en række fastgørelsessteder på selve 30 skråstiveren og/eller tværdrageren. Derved muliggøres en tilpasning efter dragere med forskellig højde og dermed tilsvarende forskelligt dimensionerede forskal1 ingsplader.Advantageously, the end (s) of the slanting brace may be formed with grooves and be provided with at least one hole to fit the fastening holes in the transverse carrier and / or in the formwork plate ribs. This makes mounting easier. The effective length of the inclined strut may be variable by means of a number of attachment points on the inclined strut and / or the transverse support itself. This makes it possible to adapt to carriers of different height and thus different dimensioned formwork panels.

Tværdrageren kan være en vinkel- eller U-skinne og på begge i 35 tværsnit fortrinsvis vinkelret på hinanden stående flige have fastgørelsessteder, fortrinsvis huller, for flangerne og/eller afstivningsribber. Derved opnås ikke blot en meget stiv udformning af tværdrageren, men også at flanger, afstivningsribber og lignende valgfrit kan forbindes med den øverste i tværsnit vandrette fligThe transverse carrier may be an angular or U-rail and, at both cross sections, preferably at right angles to each other, have attachment points, preferably holes, for the flanges and / or stiffening ribs. This results in not only a very rigid design of the transverse carrier, but also that flanges, stiffening ribs and the like can optionally be connected to the upper horizontal tab in cross section.

5 eller med den i tværsnit lodrette flade side af denne tværdrager.5 or with the cross-sectional vertical flat side of this transverse carrier.

Ved hjælp af opfindelsen opnås en dragerforskalling, der på enkel måde kan ændres i sin bredde i små trin og endvidere opnås, at der 5 til undersiden af drageren kan anvendes et meget billigt forskallingsdæk, således at forholdsvis dyre forskallingsplader undgås ved dette sted. Endvidere kan forskallingen monteres på enkel måde, og tværdrageren giver på grund af sin udformning en god afstivning af hele dragerforskallingen.The invention provides a carrier formwork which can be easily changed in its width in small steps and furthermore that a very cheap formwork deck can be used for the underside of the carrier, so that relatively expensive formwork panels are avoided at this location. Furthermore, the formwork can be mounted in a simple manner, and the transverse carrier gives a good stiffening of the entire carrier formwork due to its design.

10 I det følgende forklares opfindelsen nærmere under henvisning til tegningen. På tegningen viser: fig. 1 en dragerforskalling set fra enden med tværdra-15 geren og fastgørelsesflangerne set fra siden, fig. 2 en plantegning af den i fig. 1 viste tværdrager, fig. 3 tværdrageren set fra enden, 20 fig. 4 et til fig. 1 svarende billede af en ændret udførelsesform for dragerforskallingen, hvor fastgørelsesstederne for flangerne og skråstiverne er anbragte i en i tværsnit lodret flig af tværdrageren, 25 fig. 5 den i fig. 4 viste tværdrager set fra enden, og fig. 6 et sidebillede af en skråstiver til forbindelse af den frie ende af tværdrageren med det øverste kantområde af en lod-30 ret forskallingsplade.The invention will now be explained in more detail with reference to the accompanying drawings. In the drawing: FIG. 1 is a side view of a carrier formwork with the transverse carrier and the attachment flanges viewed from the side; FIG. 2 is a plan view of the embodiment of FIG. 1, FIG. 3 is an end view of the transporter; 4 is a view of FIG. 1 is a similar view of a modified embodiment of the carrier formwork, where the attachment points of the flanges and oblique struts are arranged in a transverse vertical section of the transverse carrier; FIG. 5 is the one shown in FIG. 4 is an end view, and FIG. 6 is a side view of an inclined strut for connecting the free end of the transverse support to the upper edge region of a vertical formwork plate.

En i sin helhed med 1 betegnet dragerforskalling har til forskalling for de lodrette sideflader af drageren forskallingsplader 2, der ved deres kanter har vinkelret på deres forskallingsdæk 3 stående 35 kantribber 4 samt eventuelt parallelt med disse forløbende afstivningsribber, der krydser hinanden og har fastgørelsessteder 5 i form af nøglehul formede huller. Til dragerforskallingen 1 hører endvidere en med 6 betegnet tværdrager, der fastholder og forbinder de lodrette forskallingsplader 2 og desuden understøtter og bærer et på DK 163444 B i ! 6 j tværdrageren liggende vandret forskallingsdæk 7 for undersiden af i drageren.A carrier formwork, referred to in its entirety as 1, has formwork for the vertical side surfaces of the carrier formworking plates 2, which at their edges are perpendicular to their formwork deck 3, 35 edge ribs 4 and optionally parallel to these extending stiffening ribs which intersect and have fastening points 5 in shape of keyhole shaped holes. In addition, the carrier formwork 1 includes a cross carrier designated by 6, which retains and connects the vertical formwork plates 2 and furthermore supports and carries one on DK 163444 B i! 6 j transverse carrier horizontal formwork deck 7 for the underside of the carrier.

Som vandret forskallingsdæk 7 er simple forskali ingsplader eller 5 forskallingsbrædder, der svarer til bredden af drageren, tilstræk- i kelige.As horizontal formwork deck 7, simple formwork panels or 5 formwork boards corresponding to the width of the carrier are sufficient.

Den til forbindelse af dragerforskallingens lodrette forskallings-plader 2 og til understøtning af forskallingsdækket 7 tjenende 10 tværdrager 6 rager med sine ender 6a ud over siderne af forskallingspladerne 2 og har i hvert af disse udragende endeområder 6a en 1 opadragende flange 8, der når op i området ved de lodrette kantribber 4 eller ved afstivningsribber på forskallingspladerne 2 og kan forbindes med disse. Flangerne 8 har i det viste udførelseseksempel 15 hver to fastgørelsessteder, der er udformede som huller, og svarer til fastgørelsesstederne henholdsvis hullerne 5 i forskallingspladernes kantribber 4. De i højre og venstre side af fig. 1 og 2 viste forbindelsesflanger 8 kan, som det senere beskrives nærmere, for- · skydes på tværdrageren 5 i dennes længderetning.The transverse carrier 6 for supporting the formwork vertical formwork plates 2 and for supporting the formwork deck 7 extends with its ends 6a beyond the sides of the formwork plates 2 and has in each of these protruding end regions 6a an upwardly extending flange 8 the area by the vertical edge ribs 4 or by stiffening ribs on the formwork plates 2 and can be connected thereto. The flanges 8, in the embodiment shown in Fig. 15, each have two fastening points which are designed as holes and correspond to the fastening places respectively the holes 5 in the edge strips of the formwork plates 4. The right and left sides of fig. 1 and 2, as will be described later, can be displaced on the transverse carrier 5 in its longitudinal direction.

20 I fig. 2 ses, at tværdrageren 6 i sin overside har to rækker af fastgørelsessteder i form af nøglehul formede huller 9, og at også den forskydelige flange 8 har dertil passende fastgørelsessteder i form af nøglehul formede huller 10. Flangen 8's fastgørelseshuller 10 25 befinder sig i vinkelret fra flangen udragende forbindelsesplader 11, der passer til oversiden af tværdrageren 6. Derved fås en meget stabil forbindelse af denne forskydelige flange 8 med tværdrageren 6, idet der findes to rækker af fastgørelseshuller 9 og også hver af flangen 8's mod hver sin side udragende holdeplader 11 har et hul 30 10. Der kan således anvendes to bolte med tværstifter eller i det mindste én bolt med en tværstift og en styrebolt til fiksering af flangen 8, der jo desuden med to bolte fastgøres til ribben 4.In FIG. 2 it can be seen that the transverse carrier 6 has two rows of fastening points in its upper side in the form of keyhole shaped holes 9, and that also the displaceable flange 8 has suitable fastening points in the form of keyhole shaped holes 10. The fastening holes 10 of the flange 8 are perpendicular connecting plates 11 extending from the flange to fit the upper side of the transverse carrier 6. This provides a very stable connection of this displaceable flange 8 with the transverse carrier 6, there being two rows of fastening holes 9 and also each of the flange 8's holding plates 11 projecting on each side has a hole 30 10. Thus, two bolts with cross pins or at least one bolt with a cross pin and a guide bolt can be used for fixing the flange 8, which in addition is secured with two bolts to the rib 4.

Derved opnås en fast forbindelse med tværdrageren 6 og samtidig en god afstivning.Thereby, a firm connection is obtained with the transverse carrier 6 and at the same time a good stiffening.

Tværdrageren 6 har, som vist i fig. 3, ved sin underside i det mindste en i tværsnit lodret afstivningsflig 12. Denne strækker sig i det væsentlige ind under fastgørelsesflangen 8, således at 35As shown in FIG. 3, at its bottom side, at least one transverse stiffening tab 12. In vertical section, it extends substantially below the fastening flange 8, such that 35

7 kræfterne fordelagtigt kan overføres fra flangerne 8 til denne afstivningsflig 12.7 the forces can be advantageously transferred from the flanges 8 to this stiffening tab 12.

I det viste udførelseseksempel opnås afstivningen af tværdrageren 6 5 ved hjælp af to vinkel skinner 13, der er anbragte neden under en vandret fladskjnne 14, og vinkel skinnen 13's vandrette flige 13a er forbundne med denne fladskinne 14, f.eks. ved svejsning, medens de lodrette flige 13b hører til forstærkningsfligen 12. Mellem disse flige 13b er der til yderligere afstivning og forstærkning af 10 afstivningsfligen 12 indsvejst fladjern 15.In the illustrated embodiment, the stiffening of the transverse carrier 65 is achieved by two angular rails 13 positioned below a horizontal flat rail 14, and the horizontal lugs 13a of the rail 13 are connected to this flat rail 14, e.g. by welding, while the vertical tabs 13b belong to the reinforcing tab 12. Between these tabs 13b there are further flat iron 15 welded and reinforced by 10 stiffening tabs 12.

Det ses navnlig i fig. 3, at der på denne måde opnås en tværdrager 6, der har et højt modstandsmoment og en god stivhed.It is particularly seen in FIG. 3, a cross carrier 6 having a high resistance torque and good stiffness is obtained in this way.

15 Flangerne 8 består ligeledes af fladt materiale, såsom fladjern, plader eller profilflige og ligger i deres brugsstilling med et kantområde af deres flade side an mod den flade side af forskallingspladen 2's kant-eller afstivningsribbe 4. Ved deres mod hinanden vendende kantområder har flangerne 8 umiddelbart oven over 20 oversiden af tværdrageren 6, der forbinder dem med hinanden, en ved kanten åben udsparing 16, der optager den på tværs forløbende nederste kantribbe 4 af den pågældende forskallingsplade 2. Derved opnås, at flangerne 5 med deres kantområde kan nå ind nær bagsiden af forskallingspladen 2' s forskallingsdæk, således at der fås den 25 størst mulige overlapning mellem flangerne 8 og ribberne 4.The flanges 8 are also made of flat material, such as flat irons, plates or profile tabs, and lie in their position of use with an edge area of their flat side against the flat side of the edge or stiffening rib 4 of the formwork plate 2. immediately above the top 20 of the transverse carrier 6 connecting them to each other, a recess 16 open at the edge which accommodates the transverse lower edge rib 4 of the respective formwork plate 2. Thus, the flanges 5 with their edge area can reach close to the back of the formwork plate 2's formwork deck so that the greatest possible overlap is obtained between the flanges 8 and the ribs 4.

Afstandene mellem hullerne 9 i tværdrageren 6 muliggør en trinvis ændring af dragerbredden i passende små trin. Samtidig kan indstillingen og monteringen gennemføres meget enkelt og hurtigt, samtidig 30 med at der alligevel kan overføres tilstrækkeligt store kræfter. Anvendelsen af vandrette forskallingsplader, der sædvanligvis kun findes med større dimensioneringsspring til forskalling af forskelligt brede dragere, er undgået.The distances between the holes 9 in the transverse carrier 6 allow a stepwise change of the carrier width in appropriate small steps. At the same time, the setting and mounting can be carried out very easily and quickly, while at the same time sufficiently large forces can be transferred. The use of horizontal formwork plates, which are usually found only with larger dimension leaps for formwork of variously wide supports, has been avoided.

35 I fig. 4-6 ses en ændret udførelsesform for opfindelsen, der især er egnet til problemløs forskalling af større dragere og til at optage de derved optrædende større kræfter.35 In FIG. 4-6, there is shown a modified embodiment of the invention, which is particularly suitable for the trouble-free formwork of larger carriers and for absorbing the larger forces resulting therefrom.

Som det ses, er tværdrageren 6 i dette tilfælde i sin brugsstillingAs can be seen, in this case the cross carrier 6 is in its position of use

8 anbragt på højkant, d.v.s. med sin med de som nøglehul formede huller 9 udformede fastgørelsessteder forsynede flade side tilnærmelsesvis lodret, og at flangerne 8 ligger an mod denne flade side. Dette ses navnlig i fig. 5.8 mounted on a high edge, i.e. the flat side provided with the key holes formed in the keyhole 9 is approximately vertical, and the flanges 8 abut this flat side. This is particularly seen in FIG. 5th

Fig. 5 viser endvidere, at tværdrageren 6 i dette udførelseseksempel ved sin flade side på den bort fra indgrebssiden med flangerne 8 vendende side har forstærkningsflige 12, der i dette tilfælde, hvor tværdrageren 6 er drejet 90° ud af den i fig. 1 og 3 viste stilling, 10 ligger tilnærmelsesvis vandret. Dette opnås ved, at tværdrageren 6 i dette tilfælde er en profilskinne, nemlig en U-skinne, hvis flige danner forstærkningsfligene 12.FIG. 5 further shows that in this embodiment the transverse carrier 6 has at its flat side, on the side facing away from the engagement side with the flanges 8, reinforcing tabs 12, in which case the transverse carrier 6 is rotated 90 ° out of the one shown in FIG. 1 and 3 are approximately horizontal. This is achieved by the transverse carrier 6 being in this case a profile rail, namely a U-rail, whose tabs form the reinforcing tabs 12.

I fig. 4 ses, at endeområdet 6a af tværdrageren 6 er forlænget ud 15 forbi tværdragerens indgrebssted med flangen 8 og i det foreliggende tilfælde også i dette område 6a har fastgørelsessteder i form af huller 9 til fastgørelse af den ene ende af en skråstiver 17, der med sin anden ende indgriber med den lodrette forskallingsplade 2 i dennes øverste kantområde. Skråstiverne 17's ender er laskeformede 20 og udgøres af flad jern 18 og har mindst ét nøgl ehul formet hul 19, der passer til fastgørelseshullerne 9 i tværdrageren 6 og forskallingspladerne 2's ribber 4. Eventuelt kan disse lasker 18 også have flere huller 19 efter hinanden, således at deres effektive længde kan ændres, dersom der skal anvendes forskallingsplader 2 med andre 25 dimensioner, eller flangen 8 skal forskydes på tværdrageren 6. Ved en sådan række af huller 9 kan skråstiveren 17 dog også følge en sådan forskydning ved forskallingsplader 2 med uændrede dimensioner.In FIG. 4, it is seen that the end region 6a of the transverse carrier 6 is extended beyond the engagement point of the transverse carrier with the flange 8 and in the present case also in this region 6a has fastening points in the form of holes 9 for attaching one end of an inclined support 17, which with its the other end engages with the vertical formwork plate 2 in its upper edge region. The ends of the oblique struts 17 are lattice-shaped 20 and are flat iron 18 and have at least one key hole-shaped hole 19 that fits the fastening holes 9 in the transverse carrier 6 and the ribs of the formwork plates 2. Optionally, these latches 18 may also have several holes 19 in succession, thus that their effective length can be changed if formwork plates 2 with other dimensions are to be used or the flange 8 must be displaced on the transverse support 6. However, for such a series of holes 9, the inclined support 17 can also follow such displacement at formwork plates 2 with unchanged dimensions.

Skråstiveren 17's fastgørelseslaske 18, der kan fastgøres til 30 tværdrageren 6, ligger i brugsstilling an mod den samme i tværsnit lodrette flade side som flangerne 8, og begge skråstiveren 17's fastgørelseslasker 18 ligger i brugsstillingen i det viste udførelseseksempel i et for disse lasker 18 og flangerne 8 fælles lodret plan, der er vinkelret på de lodrette forskallingsplader 2's for-35 skallingsdæk. Derved opnås at kraftoverførslen både til flangerne 8 og til skråstiverne 17 sker i dette plan.The slanting bracket 17 of the slanting bracket 18, which can be fastened to the transverse carrier 6, is in position of use against the same transverse vertical side face as the flanges 8, and both the slanting brackets 17 of the slanting bracket 17 are in the use position in the illustrated embodiment in one of these latches 18 and the flanges 8 common vertical plane perpendicular to the formwork deck of the vertical formwork plates 2. This results in the transfer of power to both the flanges 8 and to the oblique struts 17 in this plane.

I fig. 4 er begge flangerne 8 forskydelige i tværdrageren 6's længderetning. Dersom man tænker sig udførelsesformen ifølge fig. 1 9In FIG. 4, both flanges 8 are displaceable in the longitudinal direction of the transverse carrier 6. If one considers the embodiment of FIG. 1 9

DK 163444 BDK 163444 B

og udføre!sesformen ifølge fig. 4 kombineret, kan tværdrageren 6 være en vi nkel skinne eller eventuelt en U-skinne, der i de to vinkelret på hinanden stående grene har fastgørelsessteder i form af huller 9 for flangerne 8 og/eller skråstiverne 17, der så på pas-5 sende plader eller lasker kan have fastgørelsessteder, der passer til fastgørelsessteder på denne tværdrager 6. Det ville endog være tænkeligt at udforme enden af skråstiveren 17 og også forankringen af flangen 8 vinkelformet for yderligere at forstærke kraftoverførslen.and the embodiment of FIG. 4 combined, the transverse carrier 6 may be a single rail or, optionally, a U-rail having, in the two perpendicularly adjacent branches, mounting locations in the form of holes 9 for the flanges 8 and / or the oblique struts 17 which then fit plates or lugs may have attachment locations suitable for attachment locations on this transverse carrier 6. It would even be conceivable to design the end of the oblique strut 17 and also the anchorage of the flange 8 angularly to further enhance the power transmission.
