Opfindelsen angâr en loftsforskallingsdrager, der forbinder to af loftsforskallingens understptningsdragere med hinanden, og sammen med tilsvarende naboloftsforskallingsdragere i mellemrummet mellem loftsforskallingsdrageren og disse naboforskallingsdragere 5 fastholder og bærer dermed flugtende forskallingsplader, og hvilken loftsforskallingsdrager ved hver ende har et fastg0relsesorgan eller fastgprelsessted til lpsbar forbindelse med understotningsdragerne, og hvilken loftsforskallingsdragers længde og dermed afstanden mellem fastgprelsesorganerne eller fastgprelsesstederne er indstil-10 Telig, fortrinsvîs trinlpst indstillelig, hvorhos det ene af loftsforskall ingsdragerens fastgorelsesorganer er anbragt pâ et ende-stykke pà enden af et fpringsrpr, der sammen med dette endestykke fores forskydeligt i dets længderetning i en fdring i loftsforskallingsdrageren, og der pâ foringsrorets modsat endestykket beliggende 15 ende er anbragt et anslag, som begrænser foringsrorets udtrækslæng-de, idet det samvirker med et i loftsforskallingsdrageren anbragt modanslag, der har en mindsteafstand fra loftsforskallingsdragerens âbning, gennem hvilken foringsroret udtræder af loftsforskallingsdrageren.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a ceiling formwork carrier connecting two of the ceiling formwork supports to each other, and together with corresponding neighboring formwork supports in the space between the ceiling formwork carrier and these adjacent formwork supports 5, and which length of the ceiling formwork carrier and thus the distance between the securing means or the fixing points is adjustable, preferably stepwise adjustable, whereby one of the ceiling formwork's fastening means is arranged on an end piece at the end of a fastening screen, which is connected together with this its longitudinal direction in a casing in the ceiling formwork carrier, and a stop is arranged on the casing opposite the end piece, which limits the casing length of the casing. they cooperate with a counter-impact arranged in the ceiling formwork carrier having a minimum distance from the opening of the ceiling formwork carrier through which the casing exits the ceiling formwork carrier.
20 Fra beskrivelsen til tysk patent nr. 30 03 682 kendes loftsforskallingsdragere, der kan anbringes mellem understotnings-dragere og fastgores til disse og har en fast længde. Da den ind-byrdes afstand mellem understotningsdragerne kan variere, idet en fast afstand ikke altid passer til bygværkets stdrrelse, og i det 25 mindste to understotningsdragere derfor kan hâve en afvigende, indbyrdes afstand, er det i praksis ogsâ allerede kendt at udforme loftsforskallingsdragere pâ en sâdan mâde, at de ved udtrækning af to dele i forhold til hinanden kan indsti 11 es i længden. Den ud-trækkelige del har sædvanligvis et udvendigt tværsnit, der tilnær-30 melsesvis svarer til dragerens indvendige tværsnit. Dette har den ulempe, at dragerdelene har en forholdsvis ringe stivhed og desuden forhindrer en afstivning især i det omrâde af drageren, i hvilket den forskydelige del indtræder i den ovrige del af drageren. Da drageren, navnlig nâr den for at danne bro over storre afstande 35 foroges i sin længde, fâr en mindre bæreevne og dermed en begrænset evne til at optage tværkræfter, er disse kendte konstruktioner utilfredsstillende pâ grund af deres ringe stivhed.20 From the specification of German Patent No. 30 03 682 there are known ceiling formwork supports which can be placed between supporting supports and fastened thereto and have a fixed length. Since the mutual distance between the support beams can vary, since a fixed distance does not always correspond to the size of the structure, and at least two support supports can therefore have a different, spaced distance, it is in practice already known to form ceiling formwork supports on a in such a way that, by extension of two parts, they can be adjusted lengthwise. The extensible portion usually has an outer cross-section that corresponds approximately to the inner cross-section of the carrier. This has the disadvantage that the carrier parts have a relatively low stiffness and, moreover, prevent a stiffening especially in the area of the carrier in which the slidable part enters the other part of the carrier. As the carrier, especially as it is increased to length over its length to bridge larger distances 35, has a lower bearing capacity and thus a limited ability to absorb cross-forces, these known structures are unsatisfactory due to their low rigidity.
Formai et med opfindelsen er derfor at tilvejebringe en loftsforskallingsdrager af den indledningsvis nævnte art, der selv 2It is therefore an object of the invention to provide a ceiling formwork carrier of the kind mentioned above, which itself
DK 156447 BDK 156447 B
ved indstilling til sin stirste længde har en god tvær- og længde-stivhed samt en god modstandsdygtighed mod vridning. Samtidig skal drageren nemt kunne îndstîlies og muliggire en problèmes anbrin-gelse af et forskallingsdæk pâ den udtrukne del.when adjusted to its rigid length has a good transverse and longitudinal stiffness as well as a good resistance to torsion. At the same time, the carrier must be able to easily adjust and enable a problem of affixing a formwork tire to the extended portion.
5 Denne opgave lises ifilge opfindelsen ved, at forskallings- dragerens udtrækkelige del har mindst to fpringsrpr, der ligger ved si den af hinanden i et med forskallingsdækket parallelt plan og begge er forbundne med endestykket.5 This object is claimed in accordance with the invention in that the extendable part of the formwork carrier has at least two spring springs which lie adjacent to one another in a parallel plane parallel to the formwork cover and both are connected to the end piece.
To ved siden af hinanden beliggende fpringsrdr har den 10 fordel, at de tilsammen danner fire tilnærmelsesvis vinkelret pà forskallingsdækket anbragte rorvægge, hvorved der fâs en tilsvarende god optagelse af tværkræfter. Samtidig er der i me!1emruimnet mellem disse firingsrir plads til eventuelt npdvendige forstærkninger af selve drageren. Endvidere kan der pâ oversiden af sâdanne to parai-15 Telle rir nemt anbringes et forskallingsdækstykke, der sâledes alene ved denne anbringelsesmâde orienteres korrekt.Two adjacent spring springs have the advantage that they together form four approximately roughly perpendicular to the formwork deck, so that a corresponding good absorption of transverse forces is obtained. At the same time, in the space between these quadrilateral spaces there is room for any necessary reinforcements of the carrier itself. Furthermore, on the upper side of such two para-15 Teller rides a formwork cover piece can easily be placed, which is thus only properly oriented in this method of application.
Det er særligt fordelagtigt, dersom de parai1elle firingsrir er udformede som firkantrdr, fortrinsvis rektangulære rpr, hvis bredeste sider forl0ber tilnærmelsesvis vinkelret pâ forskallings-20 dækket. Herved opnâs, at rirene kan optage store belastninger og bijningskræfter i disse retninger, og at de pverste flade sider danner en god understptningsflade for et forskallingsdæk, der skal pâlægges ved udtrukne firingsrir. De vinkelret pâ forskallingsdækket stâende brede sider af firkantrirene danner fire flige, der især 25 virker afstivende mod udbijning af den udtrukne drager.It is particularly advantageous if the parallel quadrilaterals are designed as square tubes, preferably rectangular tubes, whose widest sides extend approximately perpendicular to the formwork deck. This provides that the riders can absorb large loads and bending forces in these directions, and that the upper flat sides form a good support surface for a formwork tire to be applied by extended quadrants. The wide sides of the rectangular deck perpendicular to the formwork deck form four tabs which, in particular, act as a stiffener against the provision of the drawn kite.
Udfprelsesformer for opfindelsen, der er af betydning, dels til opnâelse af en let udtrækkelighed af drageren og del s for dragerens stabilitet, er angivet i underkravene 3-9.Embodiments of the invention which are of importance, in part to obtain a slight retractability of the carrier and part s for the stability of the carrier, are set out in subclaims 3-9.
Navnlig ved kombination af enkelte eller flere af de foran 30 beskrevne og i de 0vrige underkrav angivne ejendommeligheder og foranstaltninger opnâs en loftsforskallingsdrager, der kan indstil-les trinlpst i sin længde og selv ved stirst mulig længdeudtrækning bibeholder en stor bijningsstivhed, idet to parallelle fpringsrir med lodrette sidevægge ogsâ giver en god bijningsstivhed og pâ grund 35 af den mindstelængde, hvormed firingsrprene i udtrukket stilling stadig fastholdes i loftsforskallingsdrageren, sammen med deres firinger ogsâ afstiver dragerens fpringsomrâde. Derved bibeholdes ogsâ en let gang af firingsrirene ved forskydningen, idet denne konstruktion af loftsforskallingsdrageren pâ grund af sin gode evne 3In particular, by combining some or more of the properties and measures described above and in the other subclaims described above, a ceiling formwork support can be obtained which can be adjusted stepwise in its length and even when staggered possible lengthening retains a large bending stiffness, with two parallel spring rows with vertical sidewalls also provide good bending stiffness and due to the minimum length at which the firings in the extended position are still retained in the ceiling formwork carrier, together with their firings also stiffens the wearer's spring area. This also maintains a slight movement of the quadruplets during the displacement, this construction of the ceiling formwork carrier due to its good ability 3

I det fplgende forklares opfindelsen og de for denne væ-sentlige enkeltheder nærmere under henvisning til tegningen. Pâ 5 tegningen viser:In the following, the invention and the details of this essential are explained in more detail with reference to the drawing. The 5 drawing shows:
Fig. 1 en perspektivisk tegning af en loftsforskallings-drager if0lge opfindelsen i udtrukket stilling, fig. 2 et længdesnit gennem den i fig. 1 viste udtrukne drager, og 10 fig. 3 i st0rre mâlestok et tværsnit gennem loftsforskal- lingsdrageren i omrâdet ved de udtrækkelige f0-ringsrpr.FIG. 1 is a perspective view of a ceiling formwork carrier according to the invention in an extended position; FIG. 2 is a longitudinal section through the embodiment of FIG. 1, and FIG. 3 on a larger scale, a cross-section through the ceiling formwork carrier in the area of the extendable liner.
En i sin helhed med 1 betegnet drager tjener til at forbinde ikke nærmere viste understptningsdragere for loftsforskallinger med 15 hinanden, sâledes at der mellem sâdanne dragere kan fastg0res dermed flugtende forskallingsplader. Forskallingspladerne kan f.eks. ved hjælp af kantribber ved deres sidekanter forbindes med drageren l's længdesider 2. Drageren 1 har selv ved sin overside et forskal = lingsdæk 3. Det ses navnlig i fig. 1 og 2, at længden af dragsrsn 1 20 og dermed afstanden mellem dens fastgprelsessteder 4, ved hvîlke den kan bringes i indgreb med understptningsdragerne, er indstillelig.A kite in its entirety designated as 1 serves to connect unshown support beams for ceiling formwork which are not shown in detail, so that escaping formwork plates can be fixed between such supports. The formwork plates can e.g. by means of edge ribs at their lateral edges are connected to the longitudinal sides of the carrier 1. The carrier 1 has a front cover tire 3 even at its upper side. 1 and 2, that the length of the pull cord 1 20, and hence the distance between its attachment points 4, at which it can be engaged with the support supports, is adjustable.
Af fig. 1 og 2 fremgâr, at det ene af fastgprelsesstederne 4 er anbragt pà et endestykke 5, der er anbragt pà to i et med for-skallingsdækket 3 parallelt plan ved siden af hinanden liggende 25 fpringsrpr 6. Disse fpringsrpr 6 kan sammen med endestykket S forskydes i deres længderetning i forhold til en fpring i loftsfor» skallingsdrageren 1 og pâ fpringsrprene 6's modsat endestykket S beliggende ender, som er optaget i drageren l's Indra, er anbragt et anslag 7, som begrænser f0ringsr0rene 6's udtrækslængde, idel det 30 samvirker med et modanslag 8, der er anbragt i drageren 1 og har en mindsteafstand fra drageren l's udgangsâbning 9. I fig. 1 og 2 ses tydeligt, at fpringsrprene 6 i deres udtrukne stilling stadig befinder sig med en betydelig længde i det indre af loftsforskal-lingsdrageren, sâledes at dette sted forbliver bpjningsstift.In FIG. 1 and 2, it is apparent that one of the attachment points 4 is arranged on an end piece 5, which is arranged on two adjacent side of the shell cover 3 parallel to the shell cover 3. These spring rings 6 can be displaced together with the end piece S in their longitudinal direction with respect to a spring in the ceiling liner 1 and on the opposite ends of the liner 6, which is accommodated in the Indra of the liner 1, a stop 7 is placed which limits the length of the liner 6 as it cooperates with a liner. 8, which is disposed in the carrier 1 and has a minimum distance from the outlet opening 9 of the carrier 1. 1 and 2, it is clearly seen that the spring bars 6 in their extended position are still a considerable length in the interior of the ceiling formwork support, so that this place remains opening pin.
35 I det viste udf0relseseksempel er de parai1 elle fpringsrpr 6 udformede som firkantrpr, hvis flade sider 6a forl0ber parallelt med dragerens forskallingsdæk 3, og hvis flade sider 6b er vinkelrette pâ forskallingsdækket 3. Fladsiderne 6 danner sâledes en god under-st0tningsflade for en forskallingsplade 10, der skal placeres oven 4In the illustrated embodiment, the parallel spring springs 6 are formed as square springs whose flat sides 6a extend parallel to the formwork deck of the carrier 3 and whose flat sides 6b are perpendicular to the formwork deck 3. The flat sides 6 thus form a good support surface 10 to be placed above 4
DK 156447 BDK 156447 B
pâ den udtrukne del af fpringsrprene 6. Endvidere giver firingsrp-rene 6's fladsider eller vægge 6b en god afstivning, idet de, som det ses i fig. 3, har en st0rre bredde end de andre fladsider 6a.on the extended portion of the latches 6. Furthermore, the flat sides or walls 6b of the latches 6 provide a good support, as as seen in FIG. 3, has a greater width than the other flat sides 6a.
Anslaget 7 dannes af en plade, der strækker sig over de 5 modsat endestykket 5 beliggende indvendige endeflader af rprene 6 og er forbundet fortrinsvis sammensvejst med rprene og danner bro over mellemrummet mellem disse. Modanslaget 8 er et mellem fpringsrprene 6 til drageren 1 fastgjort indvendigt organ, der samtidig forbinder og forstærker vandrette fpringsplader 11 og 12, der senere beskrives 10 nærmere. Derved opnâs desuden, at hele drageren 1 i sit forskyd-nings- og fpringsomrâde fâr en ekstra forstærkning, der fordelagtigt ligger mellem fpringsrprene 6, hvor der i tilfælde af Jeun en enkelt forskydelig dragerdel, der ville udfylde hele dragerens indvendige tværsnit, ikke ville være plads til en sâdan forstærkning.The abutment 7 is formed by a plate extending over the inner end faces of the bars 6 opposite the end piece 5 and preferably connected together by the bars and bridging the gap therebetween. The counter stop 8 is an inner member attached between the latching racks 6 to the carrier 1, which simultaneously connects and reinforces horizontal latching plates 11 and 12, which will be described in greater detail later. This also provides that the entire carrier 1 in its shear and spring area has an additional reinforcement advantageously located between the spring racks 6, where in the case of Jeun a single displaceable carrier portion that would fill the entire internal cross-section of the carrier would not be room for such reinforcement.
15 Til f0ring og afstivning af f0ringsr0rene 6 er der endvidere i loftsforskallingsdrageren 1 anbragt de i det foregâende nævnte plader 11 og 12, hvis indbyrdes afstand svarer til den udvendîge tykkelse af fpringsrdrene 6, hvilket ses særligt tydeligt i fig. 2.In addition, for the lining and stiffening of the casing pipes 6, the above-mentioned plates 11 and 12 are arranged in the ceiling formwork support 1, whose spacing corresponds to the external thickness of the spring pipes 6, which is particularly evident in FIG. 2nd
Det er ogsâ her fordelagtigt, at f0ringsr0rene har et firkantet 20 tværsnit, fordi pladerne 11 og 12 pâ denne mâde kan ligge tæt men dog med et til forskydeligheden tilstrækkeligt spillerum mod de flade sider 6a.It is also advantageous here that the guide tubes have a square 20 cross-section, because in this way the plates 11 and 12 may lie close, but with a sufficient clearance for the sliding, against the flat sides 6a.
F0ringspladerne 11 og 12 er anbragte i loftsforskallings-drageren 1 parai!elt med forskallingsdækket 3. Den i brugsstillingen 25 0verste f0ringsplade 11 har ved enden af loftsforskallingsdrageren 1 en opretstâende kant 13 som anslag for forskallingsdækket 3 samt for en eventuel yderligere forskallingsplade 10, der i loftsforskal-lingsdragerens udtrukne stilling skal anbringes oven pâ de udtrukne f0ringsr0r. Kanten 13 ender i samme h0jde som endestykket 5, sâledes 30 at disse to dele flugter med hinanden i dragerens sammenskudte stilling, hvor de ligger an mod hinanden.The liner plates 11 and 12 are arranged in the ceiling formwork carrier 1 parallel to the formwork deck 3. The upper liner plate 11 in the operating position 25 has at the end of the ceiling formwork carrier 1 an upright edge 13 as a stop for the formwork deck 3, and for any additional formwork plate 10, the extended position of the ceiling formwork support shall be placed on top of the extended casing. The edge 13 ends at the same height as the end piece 5, so that these two parts align with each other in the pivotal position of the carrier where they abut.
Loftsforskallingsdrageren l's sidevægge 2 har til forbin-delse med fastgprelseselementer til tilslutning af forskallingspla-der en i det viste udf0relseseksempel gennemgâende længdeslids 14, 35 hvilket ligeledes letter en tilpasning efter forskellige længder af loftsforskallingsdrageren 1 og deraf resulterende forskellige fastgprelsessteder.The side walls 2 of the ceiling formwork carrier 1 have for connecting formwork elements for connection of formwork plates a longitudinal slit 14 which is shown in the illustrated embodiment, which also facilitates an adaptation to different lengths of the ceiling formwork support 1 and resulting different fixing points.
Endestykket 5 til forbindelse med fastgprelsesstederne pâ en understptningsdragers bærehoved er en i tværsnit L-formetThe end piece 5 for connection to the attachment points on the support head of a support carrier is an L-shaped cross-section
DK 156447 BDK 156447 B
5 vinkelskinne, hvis ene gren 5a dækker endesiderne af f0ringsr0rene 6 og fikserer rprene i forhold til hinanden, og hvis anden gren 5b som fastg0relsesflange er forsynet med fastg0relsessteder 4, fortrinsvis huiler. Pâ tegningen ses et mellern de to f0ringsr0r 6 anbragt 5 forstærkningselement 15, der griber om vinkelskinnen.5 is an angular rail whose one branch 5a covers the end sides of the guide tubes 6 and fixes the ropes relative to each other, and if the second branch 5b is provided with fastening points 4, preferably by means of fastening flanges. The drawing shows a middle 5 of the two guide pipes 6, 5 reinforcing element 15 which grips the angular rail.
Det fremgâr navnlig af fig. 3, hvorledes de i tværsnit fir-kantede og dermed i aile retninger meget stive f0ringsr0r pâ for-delagtig mâde f0res ved tre sider, hvorunder den mellem rdrene anbragte fdring samtidig danner modanslaget 8 til begrænsning af 10 rdrenes udtrækslængde og desuden forstærker loftsforskallingsdrage-ren i dette omrâde. Ved opfindelsen er der sâledes opnâet en lofts-forskallingsdrager, der selv i sin stdrste længde har en god stiv-hed, uden at der kræves dyre indvendige rammer eller lignende forstærkningsmidler, idet de val.gte konstruktionselementer til 15 fpringen og til anslaget samtidig btdrager til afstivning og for-stærkning af drageren i fpringsomrâdet.This is particularly apparent from FIG. 3, in which, in cross-sectional and thus in all directions, very rigid casings are advantageously fed at three sides, during which the suspension arranged between the springs simultaneously forms the counterstroke 8 for limiting the extraction length of the 10 pipes and further enhances the ceiling formwork carrier. this area. The invention thus provides a ceiling formwork support which, even at its highest length, has a good stiffness without requiring expensive interior frames or similar reinforcing means, the selected structural elements for the spring ring and for the impact simultaneously contribute to stiffening and strengthening of the carrier in the spring area.
