Description

DK 161900 BDK 161900 B

Opfindelsen angår en loftsforskailing med bomme, der ved deres øverste ende har en forskallingsplade, og med dragere eller lignende, der forbinder bommene, samt med forskallingsplader, der kan fastgøres mellem dragerne flugtende med disse, og hvis kanter i 5 forskallingspladernes brugsstilling ligger an mod dragernes kanter, hvorhos bommen har et også under forskalling og afforskalling fastliggende uindstilleligt bæreelement med en neden under dettes forskallingsplade anbragt fastgørelsesindretning til indgreb med drageren ved hjælp af en til en løsbar forbindelse udformet flange eller en 10 lignende fastgørelsesansats.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a ceiling formwork with booms having at their top end a formwork plate and with supports or the like connecting the booms, and with formwork plates which can be fixed between the drawers flush with them, and whose edges in the position of the formwork plates abut the supports. edges, wherein the boom has a non-adjustable support element, which is also fixed during formwork and shaking, with a fastening device arranged underneath its formwork plate for engagement with the carrier by means of a flange designed for a detachable connection or a similar fastening device.

En sådan loftsforskalling kendes fra beskrivelsen til tysk patent nr. 3.003.682. Ved denne har hver drager ved sin ende en flange, der griber ind under undersiden af bæreelementets fastgørelsesindretning og kan forbindes løsbart med denne, idet forbindel-15 sesorganer, fortrinsvis forbindelsesbolte, nedefra stikkes lodret gennem denne flange. Ved denne udformning udsættes selve forbindelsesbolten ganske vist kun for trækkræfter, men ved anvendelse af sådanne forbindelsesbolte med tværstifter, der stikkes gennem nøglehulformede huller og drejes til låsestilling, udsættes tværstifterne i 20 boltens drejede stilling for tværgående overklipningskræfter. Når disse forbindelsesbolte skal løsnes, kan det endvidere, selvom boltene er drejelige, være vanskeligt at trække boltene ud, idet de kan være fastklemt i de huller, som hver bolt er ført igennem. Da den støbte flade ligger umiddelbart oven over boltene, er der i et sådant tilfælde 25 ingen mulighed for at anvende et slagværktøj.Such ceiling formwork is known from the specification of German Patent No. 3,003,682. At this end, each carrier has at its end a flange which engages underneath the underside of the carrier member's attachment and can be releasably connected thereto, with connecting means, preferably connecting bolts, projected vertically through this flange from below. In this embodiment, the connecting pin itself is subjected only to tensile forces, but by using such connecting pins with cross-pins inserted through keyhole-shaped holes and rotated to the locking position, the cross-pins in the turned position of the bolt are subjected to transverse clipping forces. Furthermore, when these coupling bolts are to be loosened, even though the bolts are pivotal, it may be difficult to pull out the bolts as they may be trapped in the holes through which each bolt is passed. Since the cast surface lies immediately above the bolts, in such a case 25 there is no possibility of using a impact tool.

Formålet med opfindelsen er derfor at tilvejebringe en loftsforskalling af den nævnte art, der har de samme fordele som den kendte loftsforskalling med hensyn til en let gennemførelse af forskallingsarbejdet og en fremstilling på enkel mide af de tilhørende forskal-30 lingsdele, men som derudover også er nem at afforskalle. Endvidere skal det opnås, at forskallingsarbejdet kan gennemføres af en enkelt person.The object of the invention is therefore to provide a ceiling formwork of the aforementioned kind which has the same advantages as the known ceiling formwork in terms of easy execution of the formwork work and a simple preparation of the associated formwork parts, but which is also easy to peel off. Furthermore, it must be achieved that the formwork work can be carried out by a single person.

Denne opgave løses ifølge opfindelsen ved, at bæreelementet i det mindste ved sin ene side og drageren ved sin mod denne side af 35 bæreelementet vendende endeflade er forbundne med hinanden over en påhægtningsforbindelse, med hvilken drageren i det mindste foreløbigt kan fastgøres svingbart til bæreelementet, og idet den føres af på-hængslingsforbindelsen kan svinges opad til en brugs- og fastgørelsesstilling, hvor i det mindste dragerens modsat påhægtningsforbindelsenThis object is solved according to the invention in that the carrier element is at least at one side and the carrier at its end face facing the side of the carrier element is connected to one another over an attachment connection with which the carrier can at least provisionally be pivotally attached to the carrier element, and being guided by the suspension connection can be pivoted upwards to a use and fastening position, where at least the carrier's opposite the attachment connection

2 beliggende ende med sin fastgørelsesflange kan forbindes med det næste bæreelement.2 with its attachment flange may be connected to the next support member.

Herved opnås, at drageren med sin ene ende først kan ophænges i skrå eller endog lodret stilling på et bæreelement og deref-5 ter svinges op i sin vandrette brugsstilling og fastgøres til det næste bæreelement. Dette kan gennemføres af en enkelt person alene. Derudover opnås ved hjælp af den førte og definerede påhægtningsforbin-delse også en lettere afforskalling.Hereby it is achieved that the carrier with its one end can first be suspended in an oblique or even vertical position on a support element and then swung up into its horizontal position of use and attached to the next support element. This can be done by a single person alone. In addition, by means of the guided and defined hook-up connection, a slight shake-off is also achieved.

Ganske vist er det fra beskrivelsen til tysk patent nr.Admittedly, from the specification to German patent no.

10 2.311.544 kendt ved en bom for forskallingsdragere til en loftsfor skalling af en anden art at anbringe en påhægtningsforbindelse mellem bæreelementet og drageren. Denne påhægtningsforbindelse ved hver ende af drageren tjener imidlertid som den eneste fastgørelse, og på bæreelementet er en i en koncentrisk cirkel liggende not og på drage-15 ren et passende fremspring til indgreb med denne not nødvendig, hvilket på grund af fremstillingsbetingede tolerancer kan medføre unøjagtighed i dragerens flugtende stilling på grund af spillerum i sideretningen i forhold til bæreelementet. Endvidere ligger drageren først med tilstrækkelig sikkerhed fast på bæreelementet, når hele 20 forskallingen er færdigfremstillet, hvilket medfører, at dragere under affors kal lingen og senere også under affors kali ingen af forskallingsplader ligger frit, kun løst hvilende i deres påhængslingsnoter. Da der til afforskallingen af dragerne er anbragt lodrette noter på bæreelementerne, der skal drejes ind under påhægtningsfremspringene, er 25 der desuden fare for, at en sådan i retningen nedad gennemgående udsparing i en uheldig drejningsstilling vil kunne medføre en utilsigtet frigørelse af dragere. Ved forskallingen ifølge den foreliggende opfindelse er i det mindste én fastgørelsesflange i brugsstillingen fikseret foruden påhægtningsforbindelsen.10,311,544 known by a boom for formwork supports for a ceiling scaling of a different kind to provide an attachment connection between the support member and the carrier. However, this fastening connection at each end of the carrier serves as the sole attachment, and on the carrier element a groove in a concentric circle and on the carrier an appropriate protuberance for engagement with this groove is necessary, which due to manufacturing tolerances may cause inaccuracy in the dragging position of the carrier due to lateral clearance relative to the support member. Furthermore, the carrier is only firmly attached to the support element when the entire 20 formwork is finished, which means that the carriers are free of all formwork plates during the process and later also under the work potassium, only loosely resting in their hanging notes. Furthermore, since the peel-offs of the dragons have vertical grooves on the supporting elements to be rotated under the locking projections, there is a danger that such a recess in the downward direction in an unfortunate turning position may result in an unintentional release of bearers. In the formwork of the present invention, at least one attachment flange in the position of use is fixed in addition to the attachment connection.

50 Endvidere kendes hvert sit forskallingssystem af en anden art fra det tyske offentliggørelsesskrift nr. 2.927.116 og beskrivelsen til tysk patent nr. 3.316.557, hvor drageren ganske vist over en påhægtningsforbindelse er forbundet med et bæreelement, men hvor bæreelementet er indstilleligt i højden, således at bæreelementet sam-55 men med drageren efter sammenhægtningen forskydes opad til brugsstilling og ved afforskalling atter forskydes i retningen nedad. Ved disse udformninger er sådanne påhægtningsforbindelser og altså ikke mindst én fastgøreisesflange som ved løsningen ifølge den foreliggende opfindelse anbragt på hver af dragerens ender og på dertil passende50 Furthermore, each formwork system of a different kind is known from German Patent Specification No. 2,927,116 and the specification to German Patent No. 3,316,557, in which the carrier is connected to a support element over an attachment connection, but where the support element is adjustable in height. , so that the carrier element together with the carrier after the joint is displaced upwards to the position of use and, when peeled off, is again displaced in the downward direction. In these embodiments, such attachment joints and thus at least one fastening flange as in the solution of the present invention are disposed on each of the ends of the carrier and suitably therefor

3 steder på bæreelementerne.3 places on the support elements.

En særlig sikker og præcis fiksering af drageren opnås ifølge opfindelsen, dersom drageren og bæreelementet også i området ved deres påhægtningsforbindelse har en flangeforbindelse med hinan-5 den, der kan låses i dragerens brugsstilling. Påhægtningsforbindelsen tjener så især til en let anbringelse og aftagning af drageren under henholdsvis forskallings- og afforskallingsarbejdet, idet drageren først ved hjælp af denne forbindelse kan fikseres foreløbigt ved sin ene ende og derefter fastlåses ved den modsatte ende og derpå også 10 fastlåses i området ved påhægtningsforbindelsen. I brugsstillingen optages kræfterne af flangeforbindelserne.A particularly secure and precise fixation of the carrier is achieved according to the invention if the carrier and the carrier element also have in the area of their attachment a flange connection with each other which can be locked in the position of use of the carrier. In particular, the fastening connection serves to facilitate the easy placement and removal of the carrier during the formwork and peel-off work, the carrier first being able to be provisionally fixed at its one end and then locked at the opposite end and then also locked in the area of the fastening connection. . In the position of use, the forces are absorbed by the flange connections.

Bæreelementet kan ifølge opfindelsen ved sine to over for hinanden beliggende forbindelsesendeflader for dragerene have en påhægtningsanordning for påhægtningsforbindelsen. Dette medfører 15 den fordel, at brugeren ikke behøver at være opmærksom på, om det pågældende bæreelement er rigtigt orienteret med dets påhægtningsanordning, idet det også ved en stilling, hvor det er drejet 180° vil passe til den pågældende drager.According to the invention, the carrier member can have a hooking device for the hooking connection at its two opposite end faces of the supports. This gives the advantage that the user does not need to be aware of whether the carrier in question is properly oriented with its locking device, as it will also fit in the position of the carrier in question at a position where it is turned 180 °.

Ifølge en fordelagtig udførelsesform for opfindelsen, der 20 især letter afforskallingen selv ved noget fastklemte fastgørelsesbolte, er ejendommelig ved, at fastgørelsesflangerne på bæreelementet og drageren i tværsnit forløber ovenfra og nedad. Derved får fastgørelsesboltene en tilnærmelsesvis med forskallingsdækket parallel eller kun lidt i forhold til dette skråt liggende orientering, således at 25 deres ender, dersom en bolt er fastklemt, kan udsættes for slagpåvirkning med et slagværktøj. Herved opnås et væsentligt lettere affors kali ingsarbejde. Endvidere opnås, at det her er selve fastgørelses- eller låsebolten, der påvirkes af tværkræfter, hvilket er en fordel, idet bolten selv kan optage større tværkræfter end dens 30 tværstift.According to an advantageous embodiment of the invention, which in particular facilitates the peel-off even by somewhat clamped fastening bolts, is characterized in that the fastening flanges of the support element and the carrier cross section from top to bottom. Thereby, the fastening bolts get approximately with the formwork deck parallel or slightly in relation to this oblique orientation, so that their ends, if a bolt is clamped, can be subjected to impact with a percussion tool. This results in a considerably easier affair for potassium removal. Furthermore, it is achieved that here the fastening or locking bolt itself is influenced by transverse forces, which is an advantage, since the bolt itself can absorb greater transverse forces than its 30 cross-pins.

En særlig udførelsesform for en loftsforskalling af den indledningsvis nævnte art er ifølge opfindelsen ejendommelig ved, at bæreelementets fastgørelsesflange har en hældning fra bæreelementets forskallingsplade i retningen hen mod bommen, og at den dermed 35 korresponderende flange på enden af drageren har en tilsvarende hældning, hvorhos bæreelementets modsat hinanden beliggende forbindelsesflanger ligger nærmere hinanden med deres nederste kanter end med deres øverste kanter. Dette letter afforskallingen betydeligt, fordi dragerens flange allerede hælder noget i den retning, i hvilkenAccording to the invention, a particular embodiment of a ceiling formwork of the type mentioned above is characterized in that the supporting flange of the support member has a slope from the formwork plate of the support element in the direction towards the boom, and that the corresponding flange at the end of the carrier has a corresponding inclination, wherein the supporting element opposite connecting flanges lie closer together with their lower edges than with their upper edges. This greatly facilitates the shelling, because the kite's flange is already inclined in the direction in which

4 den, efter at forbindelsen er løsnet, skal svinges nedad om påhægt-ningsforbindelsen. Endvidere får forbindelsesboltene derved et lidt skråt forløb, der ikke forringer den lette afforskalling og stadig muliggør anvendelse af et slagværktøj og gør indsætningen af boltene 5 lidt nedefra og opad nemmere.4 it, after the connection is loosened, must be swung downward about the attachment connection. Furthermore, the connecting bolts thereby have a slightly oblique course which does not detract from the light shedding and still allows the use of a impact tool and makes the insertion of the bolts 5 slightly lower and upward.

Udførelsesformer for opfindelsen, især med hensyn til pihægtningsforbindelsen, er angivet i kravene 5-16.Embodiments of the invention, particularly with respect to the hook attachment compound, are set forth in claims 5-16.

Især ved kombinationer af enkelte eller af alle de foran beskrevne og i kravene angivne ejendommeligheder og foranstaltninger 10 opnås en loftsforskalling, ved hvilken fordelene ved den fra beskrivelsen til tysk patent nr. 3.003.682 kendte loftsforskalling bibeholdes, og hvor forskalling og afforskalling desuden- ved hjælp af på-hægtningsforbindelsen ifølge opfindelsen kan gennemføres af en enkelt person alene. Den anden person, der ved den kendte loftsforskalling 15 skal hjælpe til med at fastholde drageren, bliver praktisk taget erstattet af påhægtningsforbindelsen. På"trods heraf formindskes også faren for ulykker, fordi påhægtningsforbindelsen er tilstrækkelig sikker, og det desuden undgås, at to betjeningspersoner skal tage hensyn til hinanden.Especially by combinations of some or all of the properties and measures described above and in the claims 10, a ceiling formwork is obtained, in which the advantages of the ceiling formulation known from the specification of German Patent No. 3,003,682 are retained and where formwork and peel-off also the use of the attachment compound of the invention can be carried out by a single person alone. The second person, who, by the known ceiling formwork 15, is to assist in holding the carrier, is practically replaced by the hook-up connection. Despite this, the danger of accidents is also reduced because the attachment connection is sufficiently secure and it is also avoided that two caretakers have to take each other into consideration.

20 I det følgende forklares opfindelsen nærmere under henvis ning til tegningen. På tegningen viser: fig. 1 et perspektivisk billede nedefra af et bæreelement ifølge opfindelsen, fig. 2 ligeledes et perspektivisk billede nedefra i noget 25 mindre målestok af en til det i fig. 1 viste bære element passende drager ifølge opfindelsen, fig. 3 et til fig. 2 svarende billede af en ånde udførelsesform for en drager ifølge opfindelsen, der kan forlænges teleskopagtigt og ligeledes passer til 30 det i fig. 1 viste bæreelement, og fig. 4 et srdebillede af en l'oftsforskalling ifølge opfindelsen med et bæreelement og fra hver side af dette udgående dragere i brugsstilling.In the following, the invention is explained in more detail with reference to the drawing. In the drawing: FIG. 1 is a bottom perspective view of a carrier according to the invention; FIG. 2 also shows a perspective view from below on a somewhat smaller scale of one for the one in FIG. 1, carrying elements according to the invention according to the invention; FIG. 3 is a view of FIG. 2 is a similar view of a spirit embodiment of a carrier according to the invention which can be extended telescopically and likewise fits the embodiment of FIG. 1, and FIG. 4 is a side view of an air-formwork according to the invention with a support element and from each side of this supporting carrier in use.

En i sin helhed med 1 betegnet loftsforskalling har bomme 35 2, der ved deres øverste ende har en forskallingsplade 3. Bommen 2 har i udførelseseksemplet et i dets helhed med 4 betegnet bæreelement, der til sammenkobling med den egentlige bom 2 ved sin underside neden under en forskallingsplade 3 har en indstiksdel 5, således som antydet i fig. 4.A ceiling formally referred to as 1 in its entirety has booms 35 2, which at their upper end have a formwork plate 3. Boom 2 has in the exemplary embodiment in its entirety a 4, a supporting element, which for coupling with the actual boom 2 at its bottom side below a formwork plate 3 has a plug portion 5, as indicated in FIG. 4th

Til loftsforskallingen 1 hører endvidere dragere 6, der forbinder de med bæreelementerne 4 forsynede bomme 2 med hinanden, samt endvidere pi tegningen ikke nærmere viste forskallingsplader, der kan fastgøres mellem dragerne 6 flugtende med disse, og 5 hvis kanter i forskallingspladernes brugsstilling ligger an mod dragerne 6's kanter 7.In addition, the ceiling formwork 1 includes supports 6 which connect the booms 2 provided with the supporting elements 4, and furthermore in the drawing no formwork plates not shown which can be fixed between the supports 6 flush with them, and 5 whose edges in the position of the formwork plates abut the supports. 6's edges 7.

Neden under forskallingspladen 3 har bæreelementet 4 fastgørelsesindretninger til indgreb med forskallingsdrageren, der igen som fastgørelsesansats har en til løsbar forbindelse udformet flange 8.Below the formwork plate 3, the carrier element 4 has fasteners for engagement with the formwork carrier, which again has as a fixing element a flange 8 formed for a detachable connection.

10 Ifølge fig. 4 forløber fastgørelsesflangerne 8 pi bæreelemen tet 4 og dragerne 6 set i tværsnit ovenfra og nedad. De til forbindelsen af flangerne 8 med hinanden tjenende fastgørelsesbolte 9 kan dermed forløbe vandret eller i hvert fald på en sådan måde, at deres modsat bolthovedet 10 beliggende ender er tilgængelige for et slag-15 værktøj, hvilket letter afforskallingen, selv dersom en bolt 9 skulle være fastklemt i forbindelseshullerne 11.10 According to FIG. 4, the attachment flanges extend 8 p in the support member 4 and the supports 6 in cross-section from top to bottom. The fastening bolts 9 serving to connect the flanges 8 can thus extend horizontally or at least in such a way that their ends located opposite the bolt head 10 are accessible to a stroke tool, which facilitates the shaking even if a bolt 9 should be trapped in the connection holes 11.

Bæreelementet 4 og drageren 6 er ved deres mod hinanden vendende endesider forbundne med hinanden ved hjælp af en på-hægtningsforbindelse 12, hvis enkelte dele ses i fig. 1-3, og hvis 20 funktionsmåde er vist i fig. 4. Ved hjælp af denne påhægtningsforbin-delse 12 er drageren 6 i det mindste foreløbig fastgjort drejeligt til bommen 2 henholdsvis bæreelementet 4. Denne påhægtningsforbindelse 12 tillader endvidere, at drageren svinges op i den i fig. 4 viste brugs-og fastgørelsesstilling, hvorunder påhægtningsforbindelsen 12 25 fører drageren på en sådan måde, at den når ind i den ønskede flugtende stilling i forhold til den næste bom 2 og dennes bæreelement 4. Derefter kan den modsat påhægtningsforbindelsen 12 beliggende ende af drageren forbindes med fastgørelsesflangen 8 på det næste bæreelement 4.The support member 4 and the carrier 6 are connected to each other at their opposite end sides by means of an attachment connection 12, the individual parts of which are seen in FIG. 1-3 and whose operation is shown in FIG. 4. By means of this hook-up connection 12, the carrier 6 is at least provisionally fastened pivotally to the boom 2 and the support element 4. This hook-up connection 12 further permits the carrier to pivot in the position shown in FIG. 4 and the position of attachment 12, under which the attachment connection 12 25 guides the wearer in such a way that it reaches the desired flush position with respect to the next boom 2 and its supporting element 4. Thereafter, the opposite end of the attachment connection 12 can be connected. with the mounting flange 8 on the next support member 4.

30 I fig. 4 ses, at drageren 6 og bæreelementet 4 også i området ved deres påhægtningsforbindelse 12 har en flangeforbindelse med hinanden, der i drageren 6's brugsstilling kan låses ved hjælp af bolte 9. For at det ved opstillingen af forskallingen ikke skal være nødvendigt at anbringe hvert bæreelement 4 i en bestemt stilling med 35 dets påhægtningsside, men derimod at gøre det muligt at anvende bæreelementet i en stilling, hvor det drejet 180°, har bæreelementet 4 ved begge sine over for hinanden beliggende sideflader til forbindelsen med en drager 6 en påhægtningsanordning for påhægtningsforbindelsen 12, der beskrives nærmere i det følgende.In FIG. 4, it is seen that the carrier 6 and the carrier element 4 also have a flanged connection with each other in the area of their locking connection, which in the position of use of the carrier 6 can be locked by means of bolts 9. In order that it is not necessary to place each carrier element when setting the formwork 4 in a particular position with its hook side, but to enable the carrier to be used in a position where it is rotated 180 °, the carrier 4 at both its opposite side faces to the connection with a carrier 6 has a hook device for the hook connection. 12, which will be described in more detail below.

Som pihægtningsforbindelse 12 er der på den ene del anbragt en på tværs af drageren 6's svingningsretning og orientering forløbende holdebolt 13, og pi den anden del anbragt en dertil passende krog 14, der kan gribe om holdebolten 13, og hvis kroggab, 5 som det ses i fig. 4 samt fig. 2 og 3 i det væsentlige vender nedad. Pihægtningsforbindeisen 12's drejningsakse 15 befinder sig, som vist i fig. 4, neden under flangeforbindelsen og dennes låseorgan tilnærmelsesvis i højde med den nederste kant 8a af fastgørelsesflangen 8. Derved er det uden videre muligt, efter at flangeforbindelserne er 10 løsnet, at svinge en drager 6 nedad. om. sia påhægtningsforbindelse 12, hvorunder også flangerne 8 frigøres fra hinanden i området ved pihægtningsforbindeisen 12.As one hook-up connection 12, one pivoting bolt 13 is arranged transversely of the pivoting direction and orientation of the carrier 6, and on the other part is provided a suitable hook 14 which can grip the retaining bolt 13 and whose hook gap 5 is as seen. in FIG. 4 and FIG. 2 and 3 essentially face down. The pivot joint 15 of pivot joint 12 is as shown in FIG. 4, below the flange connection and its locking member approximately at the height of the lower edge 8a of the fastening flange 8. This makes it possible, after the flange connections 10 are loosened, to swing a carrier 6 downwards. about. a sealing connection 12, during which the flanges 8 are also released from each other in the region of the sealing connection ice 12.

Det er særligt hensigtsmæssigt, dersom påhægtnmgsforbin-delsen 12's holdebolte 13 på bæreelemeatet 4 og påhægtningskrogen 15 eller -krogene 14 ved den ene endeflade af drageren 6, således som det også ses i udførelseseksemplet, rager ud fra den ene endeflade af drageren 6. Derved opnås, at bæreelementet 4 også kan anvendes ganske nær en væg, uden at udragende kroge virker forstyrrende. Påhægtningsforbindelsens holdebolt eller holdebolte 13 er anbragt 20 inden for omkredsen af bæreelementet 4's forskallingsplade 3 neden under denne. Bæreelementet 4's fastgørelsesflange 8 er i sit højere end holdebolten eller holdeboltene 13 beliggende område udformet med udsparinger 16 i det viste udførelseseksempel slidser, i hvilke påhægt-ningskrogene 14 kan indføres. I udførelseseksemplet ses, at drageren 25 6 ved den til pihægtningsforbindeisen 12 tjenende ende har i det mindste to parallelt i afstand fra hinanden anbragte kroge 14. Bæreelementet 4's endeflange 8 har derfor også to slidser 16 til indførslen af disse kroge 14. På bæreelementet 4 kunne der være anbragt i det mindste én parallelt med fastgørelsesflangen 8‘s plan forløbende gen-30 nemgående holdebolt 13. I det viste udførelseseksempel er der imidlertid anbragt to fra bæreelementet 4's sidevægge 17 udgående med hinanden flugtende boltdele 13, der skal samvirke med drageren 6's kroge 14. Da en flangeforbindelse i brugsstillingen overfø?er kræfterne mellem drageren og bæreelementet, er sådanne forholdsvis korte 35 bolte 13 tilstrækkelige.It is particularly convenient if the retaining bolts 13 of the attachment compound 12 on the support member 4 and the attachment hook 15 or hooks 14 at one end face of the support 6, as also seen in the embodiment, protrude from one end face of the support 6. The support member 4 can also be used quite close to a wall without protruding hooks. The retaining bolt or retaining bolt 13 of the fastening connection is disposed 20 within the circumference of the formwork plate 3 of the support member 4 below it. The fastening flange 8 of the support element 4 is formed in its region higher than the retaining bolt or retaining bolts 13 with recesses 16 in the illustrated embodiment slots into which the hook hooks 14 can be inserted. In the exemplary embodiment, it is seen that the carrier 25 6 at the end serving to the hook-up connection ice 12 has at least two spaced hooks 14. The end flange 8 of the support member 4 therefore also has two slots 16 for the insertion of these hooks 14. On the support member 4 at least one through 30 retaining bolt 13 running parallel to the plane of the fastening flange 8, however, in the illustrated embodiment, two bolt parts 13 projecting from one another of the supporting members 4 which are flush with the hooks of the carrier 6 are arranged. 14. Since a flange connection in the position of use exerts the forces between the carrier and the support member, such relatively short bolts 13 are sufficient.

20 Derved opnås, at brugeren først kan ophænge denne udtrækkelige drager 6 på et bæreelement 4 og derefter trække den udtrækkelige del 19 ud til den nødvendige længde hen til det næste bæreelement 4 og fastgøre den til dette.In this way, it is achieved that the user can first hang this retractable carrier 6 on a support member 4 and then extend the extendable member 19 to the required length to the next support member 4 and attach it to it.

Ifølge opfindelsen kan der fordelagtigt på den teleskopagtigt 25 forlængerbare drager 6‘s udtrækkelige del 19 ved et endestykke 22, der afslutter denne udtrækkelige del 19‘s føringsrør 21, være anbragt en kasseformet forlængelse 23, der ved sin ende har en forbindelsesflange 8, som er forsynet med fastgørelsesanordningen 11 til forbindelse med bæreelementet 4, og befinder sig i afstand fra 30 enden af føringsrøret eller føringsrørene 21. Herved opnås, at forbindelsesbolten 9's modsat bolthovedet 10 beliggende ende er tilgængelig for at slagværktøj, dersom affors kali ingen volder vanskeligheder.According to the invention, advantageously, on the telescopic 25 extensible carrier 6 extendable portion 19 at an end piece 22 terminating this extensible portion 19 guide tube 21, a box-shaped extension 23 having at its end a connecting flange 8 may be provided. is provided with the fastener 11 for connection with the support member 4, and is spaced from the end of the guide tube or guide tubes 21. Hereby it is obtained that the opposite end of the connecting bolt 9 is accessible for impact tools if the barrel of the barrel does not cause any difficulties.

Som allerede nævnt opnås forbindelsen af fastgørelsesflangerne 8 med hinanden og deres sammenlåsning ved hjælp af nøglehul-35 formede huller 11 som fastgørelsessteder og fastgørelsesbolte 9 med tværstifter, der er antydet i fig. 4.As already mentioned, the connection of the fastening flanges 8 to each other and their interlocking are achieved by means of keyhole-shaped holes 11 as fastening points and fastening bolts 9 with cross pins indicated in FIG. 4th
