Description

DK 152145 BDK 152145 B

Opfindelsen vedrører et støtteapparat til et forskallingselement eller et lignende byggeelement som angivet i indledningen til krav 1.The invention relates to a support apparatus for a formwork element or a similar building element as set forth in the preamble of claim 1.

Fra DE-AS 22 65 406 og DE-AS 26 48 281 kendes 5 støtteapparater af denne art, som specielt anvendes til understøtning af loftsforskallingselementer. Disse støtteapparater har et støttehoved (støtteleje), der fastgøres til den bære- eller støttekonstruktion, der skal understøttes. Støtterøret er fastgjort dre-10 jeligt til støttehovedet, så det kan anbringes i horisontal stilling. Det er på denne måde efter endt forskallingsarbejde muligt at bringe et loftsforskallingselement ud af f.eks. vinduet i en nybygning, uden at støttehovedet behøver løsnes fra loftsforskal-15 lingselementet. De kendte apparat har på støttehovedet en støtteplade, hvorfra fire profilstivere vender. Disse nedadgående stivere er i deres nederste ende fast forbundne ved hjælp af vinkeljern eller på-svejste broer. Støtterøret, der forløber mellem dis-20 se stivere, er i et enkelt plan drejeligt om en lejetap og bliver i arbejdsstilling sikret mod utilsigtet drejning ved hjælp af en føringsmuffe. Ved de kendte støtteapparater er det en ulempe, at støtterøret kun er drejeligt om en fast akse hvilket vil sige i kun 25 én retning, og at svingområdet på grund af støttehovedets konstruktion er begrænset.. Dette medfører, at støtterørerne, som på sådanne støtteapparater er anbragt i det samme vertikalplan på loftsforskallingselementet, i sammenklappet tilstand indbyrdes for-30 styrrer hinanden og dermed besværliggør håndteringen af loftsforskallingselementet. Det er ganske vist principielt muligt at skille støtterøret fra støttehovedet, men så er det ved genanvendelse nødvendigt at udføre monteringsarbejde, f.eks. indsættelse af 35 støtterøret i drejelejet.From DE-AS 22 65 406 and DE-AS 26 48 281 5 support devices of this kind are known, which are especially used for supporting ceiling formwork elements. These support devices have a support head (support bearing) that attaches to the support or support structure to be supported. The support tube is pivotally attached to the support head so that it can be placed in a horizontal position. In this way it is possible, after finishing formwork, to bring out a ceiling formwork element from e.g. the window of a new building without the support head having to be detached from the ceiling formwork element. The known apparatus has on the support head a support plate from which four profile springs face. These downwardly extending struts are fixed at their lower ends by means of angular irons or welded bridges. The support tube extending between these struts is rotatable in a single plane about a bearing pin and is secured in working position against accidental rotation by means of a guide sleeve. In the known support devices, it is a disadvantage that the support tube is only rotatable about a fixed axis, that is, in only one direction, and that the swivel area due to the structure of the support head is limited. This means that the support tubes which on such support devices are placed in the same vertical plane on the ceiling formwork element, in a collapsed state interferes with each other and thus makes the handling of the ceiling formwork element difficult. It is, in principle, possible to separate the support tube from the support head, but then in case of recycling it is necessary to carry out assembly work, e.g. insertion of the 35 support tube into the swivel.

Med opfindelsen anvises et støtteapparat af den indledningsvis nævnte art, hvor det er enkelt at indsætte støtterøret og hvor dette inden for et bredt område kan svinges i flere retninger.The invention discloses a support apparatus of the kind mentioned above, where it is easy to insert the support tube and where it can be pivoted in a wide range in a wide range of directions.

5 Et mål med opfindelsen er følgelig at angive et støtteapparat af den indledningsvis nævnte art, på hvilket støtterøret kan drejes i flere retninger, og på hvilket indsættelse af støtterøret er enkel.Accordingly, an object of the invention is to provide a support apparatus of the kind mentioned at the outset, on which the support tube can be rotated in several directions and on which insertion of the support tube is simple.

Dette opnås ifølge opfindelsen ved, at støt-10 teapparatet er udført på den i den kendetegnende del af krav 1 angivne måde.This is achieved according to the invention in that the support apparatus is constructed in the manner specified in the characterizing part of claim 1.

I underkravene angives der fordelagtige udførelsesformer for opfindelsen.The subclaims disclose advantageous embodiments of the invention.

Ifølge opfindelsen er der angivet en konstruk-15 tion af støtteapparatet, hvor støtterøret ikke forløber centralt mellem flere af støttehovedets stivere, men hvor støttehovedet i nærheden af den ene ende har et leje til støtterøret. Støttehovedet er dermed ikke placeret symmetrisk om støtterørets akse, 20 men er forsat til den ene side herfor. Støttehovedet har en øvre rammedel, hvorfra to stivere fører nedad og er fastgjort til en holder. Denne holder har et slidsestyr, hvorigennem støtterøret i arbejdsstillingen forløber. Indsætning af støtterøret i slidse-25 styret går forholdsvis let fra hånden. Støtterørets øvre ende angriber på et anlæg i støttehovedet. Ved fjernelse af støtterøret tages dette ud af slidsesty-ret og kan derefter svinges eller drejes i vilkårlige retninger.According to the invention, there is disclosed a construction of the support apparatus in which the support tube does not extend centrally between several of the support head struts, but where the support head has a bearing for the support tube near one end. The support head is thus not symmetrically positioned about the axis of the support tube, but is positioned to one side thereof. The support head has an upper frame portion from which two struts lead downwards and are attached to a holder. This holder has a sliding guide through which the support tube in the working position extends. Inserting the support tube into the slot guide is relatively easy from the hand. The upper end of the support tube attacks an abutment in the support head. When removing the support tube, this is taken out of the slot guide and can then be swiveled or turned in any direction.

30 Ved en videre udførelsesform for opfindelsen er der til holderen fastgjort en tredie stiver, som forløber på den ene side af det af begge de andre sti-In a further embodiment of the invention, a third strut is attached to the holder which extends on one side of it by both of the other struts.

3 vere dannede plan. Denne tredje stiver har specielt vist sig fordelagtig, når der med støtteapparatets øvre rammedel understøttes en eller to bjælker, og der over disse bjælker og vinkelret derpå forløber 5 andre dragere. Den tredje stiver kan med en befæstelsesplade fastgøres til disse dragere, hvorved støtteapparatet understøtter såvel bjælkerne som drager-ne. Befæstelsespladen på denne tredje stiver er fortrinsvis drejelig, for at pladen ved en vilkårlig 10 stilling af den tredje stiver til enhver tid kan tilpasses undersiden af en drager. Længden af denne tredje stiver er afpasset, så den rager op over det øvre rammeelements støtteplan og dermed når op til den højere liggende drager.3 springs formed plan. This third strut has proved particularly advantageous when one or two beams are supported with the upper frame part of the support apparatus, and 5 other supports extend over these beams and perpendicularly thereafter. The third strut can be attached to these supports by means of a fastening plate, whereby the supporting apparatus supports both the beams and the supports. Preferably, the fastening plate of this third strut is rotatable so that the plate can be adapted at any time to the third strut at any time on the underside of a carrier. The length of this third strut is adjusted so that it protrudes above the support frame of the upper frame member and thus reaches the higher-lying kite.

15 Støtterøret har i sin øvre ende en aftagelig flange, hvormed belastningen fra anlægget i den øvre rammedel overføres til støtterøret. Om støtterøret er lagt en løkke, således at det udtagne støtterør i påkommende tilfælde vil hænge i denne løkke. Løkken er 20 fastgjort til støttehovedet, så støtterøret og det tilhørende støttehoved ikke tilfældigt falder fra hinanden.The support tube has a removable flange at its upper end, whereby the load from the abutment in the upper frame portion is transferred to the support tube. Whether the support tube is a loop so that the removed support tube will hang in that loop, if applicable. The loop is attached to the support head so that the support tube and associated support head do not fall apart at random.

På den øvre rammedel er fastgjort en spænde-plade, som udgør anlægget. Denne spændeplade har en 25 central åbning, i hvilken der kan skrues en gevindboldt .Attached to the upper frame portion is a clamping plate which constitutes the plant. This clamping plate has a central opening in which a threaded bolt can be screwed.

Gevindbolten tjener for det første til fastgørelse af støttehovedet til bjælken, og for det andet bliver der på dens nedre ende skruet et centre-30 ringsstykke, som griber ind i den øvre ende af støtterøret, og som sikrer dette mod forskydning.Firstly, the threaded bolt serves to secure the support head to the beam, and secondly, a centering piece is screwed at its lower end which engages the upper end of the support tube and secures it to shear.

Gevindbolten har i sin øverste ende en slids, hvori et kileelement kan indsættes. Dermed er en hurtig fastgørelse til de understøttede bjælker mulig.The threaded bolt has a slot at its upper end into which a wedge element can be inserted. This enables fast attachment to the supported beams.

I en videre udførelsesform for opfindelsen er 5 der på spændepladen sat en fodplade. Denne konstruktion gør det muligt at tilpasse støttehovedet til vilkårlige faconer af bjælker eller dragere, idet det udelukkende ergrundpladen, der skal udskiftes.In a further embodiment of the invention, a foot plate is provided on the clamping plate. This construction makes it possible to adapt the support head to any shapes of beams or carriers, with the sole base plate to be replaced.

I endnu en udførelsesform for opfindelsen er 10 den med slidsestyret forsynede holder, hvori støtterøret er styret, udstyret med en låsemekanisme, der holder støtterøret i slidsestyret, og som f.eks. kan være udført som sakseplader. Disse sakseplader er hængslede, så de kan lukkes om det i slidsestyret 15 siddende støtterør og sikre dette mod at glide ud af slidsestyret. For tilpasning til forskellige støtterørsdiametre har saksepladerne flere på en cirkelbue liggende låsehuller.In yet another embodiment of the invention, the slit-guided holder in which the support tube is guided is provided with a locking mechanism which holds the support tube in the slit guide, and as e.g. can be made as scissors. These scissor plates are hinged so that they can be closed about the support tubes seated in the slot guide 15 and secure this against sliding out of the slot guide. For adaptation to different supporting pipe diameters, the scissor plates have several locking holes lying on a circular arc.

Til fastgørelse af dragere på den tredje sti-20 ver kan denne tredje stiver på enden have fastgjort en svingbøjle eller en drejelig vinkel. Ved hjælp af svingbøjlen er fastgørelse af en drager med f.eks. firkantprofil særlig enkel. Svingbøjlen drejes, så drageren med sin. grundflade kan indføres i bøjlen.For attaching supports to the third strut, this third strut on the end may have secured a pivot bracket or a pivoting angle. By means of the swing bracket, attaching a carrier with e.g. square profile particularly simple. The swivel bracket is turned so that the kite with its. ground surface can be inserted into the hoop.

25 Dernæst drejes bøjlen og griber i denne drejede stilling med overgribende ender over drageren og holder dermed den øvre ende af den tredje stiver til denne drager.25 Next, the hoop is rotated and engages in this pivotal position with horizontal ends over the carrier, thus holding the upper end of the third strut to this carrier.

Yderligere enkeltheder ved opfindelsen bliver 30 i det følgende nærmere beskrevet og uddybet ved hjælp af de på tegningen viste udførelseseksempler.Further details of the invention will be described and elaborated upon in the following by means of the exemplary embodiments shown in the drawing.

Fig. 1 viser et eksempel på et støtteapparat ifølge opfindelsen. Støtteapparatet er sammensat af et støtterør 1 og et støttehoved 2. Støttehovedet 2 har en øvre rammedel 3, 25 fra hvis ene ende en diagonalt forløbende stiver 5 og fra hvis anden ende en lodret stiver 4 fører nedefter. Ved den nedre ende af stiverne 4 og 5 er anbragt en holder 8, som er forsynet med et slidsestyr 7. I dette slidsestyr 7 befinder støtterøret 1 sig. I arbejdsstil-30 ling ligger den øvre ende af støtterøret 1 mod etFIG. 1 shows an example of a support apparatus according to the invention. The support apparatus is composed of a support tube 1 and a support head 2. The support head 2 has an upper frame member 3, 25 from one end of which is a diagonally extending strut 5 and from whose other end a vertical strut 4 leads downwards. At the lower end of the struts 4 and 5 is arranged a holder 8, which is provided with a slot guide 7. In this slot guide 7 the support tube 1 is located. In working position, the upper end of the support tube 1 lies against one another

6 anlæg 6 på den øvre rammedel 3. I det viste tilfælde er anlægget 6 en spændeplade, som er svejst på den øvre rammedel. Støtterøret 1 er for at opnå en bedre kraftfordeling i sin øvre ende forsynet 5 med en flange 16 udført som en ydre ringflange, der i arbejdsstilling ligger an mod undersiden af spæn-depladen 6. I udførelsen i fig. 6 er flangen en slags adaptor, der er aftagelig forbundet med støtterøret 1. Hertil har flangen 16 en om den øvre ende af 10 støtterøret 1 gribende muffeformet rørforlængelse 16a, der griber om en ydre ringformet fortykkelse la på støtterøret, og neden for fortykkelsen sikrer støtterøret 1 mod forskydninger i aksial retning, dvs. mod at løsne sig, ved hjælp af radialt indadrettede 15 bolte eller lignende. Specielt ved udførelsesformen i fig. 6 er det hensigtsmæssigt, hvis flangen 16 har et kantet, fortrinsvis kvadratisk grundsnit.6 abutment 6 on the upper frame member 3. In the case shown, abutment 6 is a clamping plate which is welded on the upper frame member. In order to achieve a better distribution of force at its upper end, the support tube 1 is provided with a flange 16 constructed as an outer annular flange, which in working position abuts the underside of the clamping plate 6. In the embodiment in fig. 6, the flange is a kind of adapter removably connected to the support tube 1. For this purpose, the flange 16 has a sleeve-shaped tubular extension 16 gripping around the upper end of the support tube 1, which engages an outer annular thickness 1a of the support tube, and below the thickening secures the support tube. 1 against shifts in axial direction, i.e. against loosening, by means of radially inwardly 15 bolts or the like. Especially in the embodiment of FIG. 6, it is convenient if the flange 16 has an angular, preferably square, section.

Spændepladen 6 er udført med en central gennembrydning 11, som har indvendigt gevind 13. Som 20 specielt fig. 1 og 10-13 viser, er udførelsen således, at der neden for gennembrydningen 11 er et med det indvendige gevind 13 forsynet rørstykke, som f.eks. er svejst til spændepladen 6. I dette indvendige gevind skrues gevindbolten 14, så den både ned- og 25 opefter stikker frem fra spændepladen 6. På den nedre ende af gevindbolten 14 skrues et centreringsstykke 15, som er tilpasset støtterøret l's indre diameter. Støtterøret 1 griber om dette centreringsstykke 15 og er derved sikret mod forskydning. Por 30 at lette tilpasningen er centreringsstykket 15 somThe clamping plate 6 is provided with a central breakthrough 11, which has an internal thread 13. As 20 especially FIG. 1 and 10-13, the embodiment is such that, below the breakthrough 11, there is a pipe piece provided with the internal thread 13, such as e.g. is welded to the clamping plate 6. In this internal thread, the threaded bolt 14 is screwed so that it protrudes downwards and upwards from the clamping plate 6. On the lower end of the threaded bolt 14 is screwed a centering piece 15 adapted to the inner diameter of the support tube 1. The support tube 1 engages this centering piece 15 and is thereby secured against displacement. Pore 30 to facilitate alignment is centering piece 15 which

7 vist i fig. 10-13 forsynet med en konisk del 15a.7 shown in FIG. 10-13 provided with a tapered portion 15a.

Gevindbolten 14 har i sin øverste ende en spalte 25, hvorigennem et kileelement 26 kan stikkes.The threaded bolt 14 has at its upper end a slot 25 through which a wedge member 26 can be inserted.

5 Af fig. 1 ses det videre, at der er en tredje stiver 9, som i forhold til det af stiverne 4 og 5 dannede plan stikker ud på den ene side heraf.5 From FIG. 1, it is further seen that there is a third strut 9 which protrudes on one side thereof relative to the plane formed by strut 4 and 5.

Denne tredje stiver 9 tjener ligeledes til fastgørelse af støttehovedet 2 til forskallingselementet, 10 f.eks. et loftsforskallingselement. Stiveren 9 er fortrinsvis s/ingbar, idet dens omdrejningsakse 91 forløber parallel med det af stiverne 4 og 5 dannede plan.This third strut 9 also serves to attach the support head 2 to the formwork element, 10 e.g. a ceiling formwork element. The strut 9 is preferably adjustable, with its axis of rotation 91 extending parallel to the plane formed by strut 4 and 5.

Den tredje stiver 9 har i sin yderste ende 15 en fastgørelsesplade 10, som fortrinsvis ved hjælp af et hængsel 90 er fastgjort til denne ende (fig. 4).The third strut 9 has at its outer end 15 a fastening plate 10, which is preferably secured to this end by means of a hinge 90 (Fig. 4).

Fig. 2 viser flere enkeltheder på støtteapparatet ifølge opfindelsen. I den viste situation er støtterøret 1 i sin arbejdsstilling, hvorved flangen 20 16 nedefra ligger an mod spændepladen 6. Spændepla- den 6 har ribber 61, der forløber i samme retning som den øvre rammedel 3. Ribberne 61 tjener til at optage to U-profiler og sikre støttehovedet mod forskydning.FIG. 2 shows several details of the support apparatus according to the invention. In the illustrated situation, the support tube 1 is in its working position whereby the flange 20 16 from below abuts against the clamping plate 6. The clamping plate 6 has ribs 61 extending in the same direction as the upper frame member 3. The ribs 61 serve to receive two U profiles and secure the support head against displacement.

25 Holderen 8 har en spærremekanisme 80 til at holde støtterøret 1 på plads i slidsestyret 7.The holder 8 has a locking mechanism 80 for holding the support tube 1 in place in the slot guide 7.

I udførelserne i fig. 2, 8 og 9 er spærremekanismen 80 udført ved hjælp af på holderen 8 anbragte sakseplader 20, 21, der er drejelige om en lejetap 29.In the embodiments of FIG. 2, 8 and 9, the locking mechanism 80 is provided by means of scissor plates 20, 21 arranged on the holder 8 pivotally about a bearing pin 29.

30 Disse sakseplader 20, 21 har låsehuller 24, hvor-These scissor plates 20, 21 have locking holes 24,

DK 152145BDK 152145B

8 med saksepladerne kan sikres mod at springe op. Derved forhindres støtterøret 1 i at glide ud af slidsestyret 7. Låsehullerne 24 er anbragt på en cirkelbue for ved isætning af bolte 24a (fig. 2) at 5 muliggøre låsning af støtterør 1 med forskellige diametre.8 with the scissor plates can be secured against jumping. Thereby, the support tube 1 is prevented from sliding out of the slot guide 7. The locking holes 24 are arranged on a circular arc to enable locking of the support tube 1 with different diameters 5 by inserting bolts 24a (Fig. 2).

I udførelsen i fig. 4 er låsemekanismen 80 udført med styr 82 bestående af to på hver sin side af slidsestyret 7 anbragte og fra holderen 8 opad 10 forløbende styrebolte eller skinner med indbyrdes voksende afstand, hver især med et centreringselement 83, som kan bevæges op og ned, hvorved de to kloformede centreringselementer fra hver sin side ligger an mod støtterøret 1, jvf. fig. 9a. De kæbelignende 15 centreringselementer 83 har glideelementer 84, f.eks. glidesko eller -muffer, som er i indgreb med styrene 82. Af fig. 4 fremgår endvidere, at centre-ringselementeme 83 til fastholdelse af disse i centreringsstilling står i forbindelse med et spærre-20 arrangement 85, som har en også fra holderen 8 opad forløbende klemplade 86, der har åbninger 87 i forskellige højder til indsætning af et ovenfra på centreringselementerne anliggende og til låsemekanismen 85 hørende holdeelement 88. Derved er der på begge 25 sider af den som modhold til holdeelementet 88 virkende klemplade 86 lejer 89 til det indsatte holdeelement 88, hvilket sidste er udført som en kile. Denne form for låsning er i forhold til de drejelige sakseplader 20, 21 betydelig mere robust, .In the embodiment of FIG. 4, the locking mechanism 80 is provided with guide 82 consisting of two on each side of the slot guide 7 and spaced guide bolts or rails extending upwardly from each holder 8 upwardly, each with a centering element 83 which can be moved up and down, two claw-shaped centering elements on each side abut the support tube 1, cf. 9a. The jaw-like centering members 83 have sliding members 84, e.g. sliding shoes or sleeves which engage the guides 82. 4 further shows that the centering members 83 for holding them in the centering position are connected with a locking arrangement 85 which has a clamping plate 86 extending upwardly of the holder 8 having apertures 87 at different heights for inserting a top view. abutting on the centering members and holding member 88 of the locking mechanism 85. Thus, on both 25 sides of the clamping plate 86 acting against the holding member 88, bearing 89 of the inserted holding member 88, which is last constructed as a wedge, is provided. This kind of locking is considerably more robust with respect to the rotary scissor plates 20, 21.

9 liggør en endnu lettere og hurtigere håndtering end de som støtterør markedsførte bygningsstøtter.9 provides even easier and faster handling than the building supports marketed as support pipes.

Ved en i fig. 4a vist i forhold til fig. 4 ændret udførelsesform består låsemekanismen 85 af 5 i styrene 82 i forskellige højder anbragte boringer 82a, som ved tilpasning til forskellige støtterørsdiametre vil komme til at ligge oven-og nedenfor glideelementerne 84, og hvorigennem der kan indsættes et som en U-formet dobbeltstikbolt udført låseelement 10 88a. Det ovenfor glideelementet 84 indstukne kortere ben af låseelementet 88a forhindrer centreringselementerne 83 i at vandre opad og dermed åbne sig, medens det neden for glideelementet 84 indstukne længere ben af låsestykket tjener som anlæg for gli-15 deelementerne 84.In one of FIG. 4a shown in relation to FIG. 4, the locking mechanism 85 consists of 5 in the guides 82 at different heights bores 82a which, when adapted to different supporting pipe diameters, will lie above and below the sliding elements 84 and through which a locking element made as a U-shaped double bolt can be inserted. 88a. The shorter legs of the locking member 84, which is cut above the locking member 88a, prevents the centering members 83 from moving upwards and thus opening up, while the longer legs of the locking member, which are arranged below the sliding member 84, serve as abutments for the sliding members 84.

Som det kan ses i fig. 2, er der om støtterøret 1 lagt en løkke 22, der er fastgjort til en karabinhage 23. Karabinhagen 23 er hægtet i en udsparing i den øvre rammedel 3.As can be seen in FIG. 2, a loop 22 is attached to the support tube 1 which is attached to a carabiner 23. The carabiner 23 is secured in a recess in the upper frame part 3.

20 Skal støtterøret 1 fjernes, så åbnes sakse pladerne 20, 21 henholdsvis centreringselementerne 83 på holderen 8, og støtterøret 1 tages ud af slidsestyret 7. Da det udtagne støtterør 1 nu kun er fastgjort til den øvre rammedel 3 med den neden 25 for flangen 16 liggende løkke 22 og karabinhagen 23, kan det drejes og lægges i vilkårlige retninger, f.eks. parallelt med den øvre rammedel 3's længdeakse. Støtterøret l's bevægelighed er kun begrænset af det af stiverne 4, 5 og 9 dannede treben, som dog 30 stadigvæk tillader støtterøret at dreje igennem en vinkel på ca. 270°.20 If the support tube 1 is to be removed, the scissors plates 20, 21 and the centering elements 83 are opened on the holder 8, respectively, and the support tube 1 is taken out of the slot guide 7. Since the removed support tube 1 is now only attached to the upper frame part 3 with the bottom 25 for the flange 16 lying loop 22 and carabiner 23, it can be rotated and laid in any direction, e.g. parallel to the longitudinal axis of the upper frame portion 3.
