Definitions
- the invention relates to a length-adjustable support, in particular ceiling prop for formwork, comprising a hollow outer profile, in which an inner profile is axially displaceable is arranged, wherein the inner profile a variety of Has pegging holes.
- Adjustable supports are used in particular in construction used for slab formwork on a variety adjustable supports can be placed. To get one on a variety of length-adjustable supports The exact length of the slab formwork must be adjusted individual supports can be set very precisely. Usually the length-adjustable supports are fine-tuned additionally with the help of a suitable Leveling instrument.
- International application WO 93/20 311 discloses one adjustable support according to the generic term of Claim 1 and describes a height-adjustable support for Formwork in construction, on the outer circumference of the inner tube a scale is arranged in the longitudinal direction. This can the length-adjustable support without any additional aids the desired length can be set because the respective Read the total length of the support directly and open the support the desired gauge block must be set to the centimeter.
- a separate measurement scale can be done by the Attach a tape measure by printing one or done by impressing a scale.
- the Attaching a measuring tape requires your own Manufacturing step to attach the same by a separate tape measure intensely with the support over the entire Length is connected and is protected from the fact that the Telescoping the prop is damaged or becomes illegible.
- the invention has for its object an integrated Propose adjustment aid for telescopic supports that is simple is to manufacture and a simple rough adjustment one adjustable support allowed.
- both hollow outer profile and the inner profile an annular Cross-section.
- they are optical effective deformations or stamped.
- Either an embossing in which a deformation within the wall of the processed material, as well as deep embossing, where the wall of the processed material deforms itself as well as punching are easy to do Manufacturing processes that work together with the formation of the Stake holes can be made. Therefore, under Use one of the above molding processes the optically effective deformations in the production of the Inner profile can be integrated.
- Another advantage lies in that the durability of the deformations thus formed is equal to the life of a length-adjustable support.
- they are optical deformations in the immediate vicinity of the Stake holes arranged. This has the advantage that the operating personnel the subject of the invention on very can handle easily. To make a rough adjustment of the To make the length of the adjustable support, everyone will coarsely adjustable supports except for a peg hole pulled out of the same marker.
- optical deformations are 90 degrees radial staggered to the peg holes, this comes an ergonomically favorable attitude of the operating personnel counteracting this by the optically acting deformations Has eyes and a safety pin from the side into one can insert the desired peg hole.
- the optically effective deformations are preferably in one periodically recurring sequence along the inner profile arranged.
- the optically acting deformations in Form of the digits 0 to 9 or in the form of letters or Form symbols.
- This can be a rough setting several spaced apart adjustable in length Supports, which are each brought to the same rough dimensions should be simplified by making all the length adjustable For example, prop up to one with the letter D marked peg hole.
- prop up to one with the letter D marked peg hole At a periodically recurring sequence of numbers from 0 to 9 is true a mix-up of marked out holes possible due to the relatively large distance from Stakeout holes with the same marking, however unlikely.
- the optically effective deformations preferably have a Expansion with respect to the axial direction of the inner profile of 10 mm to 20 mm, preferably about 15 mm. This is one given sufficient size to visually see the deformations easily recognizable, at the same time the deformations however not so large that it becomes a notable one Weakening of the inner profile comes.
- the support has a Threaded spindle for fine adjustment.
- a threaded spindle for fine adjustment can length-adjustable support according to the invention to an exact Length measure. This allows one on one Large number of adjustable formwork supports using a measuring device such as one Leveling device, through the fine adjustment of the individual, load-bearing, length-adjustable supports in a desired Location.
- Knurling preferably runs in the longitudinal direction of the Inner profile in the area of optically effective deformations. This can be in different knurls and corrugations be executed over the entire length of the inner profile are arranged and highlighting the optical Deformations in the form of the embossed markings serve.
- a length-adjustable support is shown, the is generally designated by reference number 10.
- the length-adjustable support consists of a base plate 12, which is rigidly connected to an outer profile 14, for example by a circumferential weld seam.

- the inner profile slidably arranged in the outer profile 14 is formed in terms of its outer dimension that it on the one hand, can be easily inserted into the outer profile 14, on the other hand also through the inner wall of the outer profile to be led. Therefore, in the illustrated embodiment also formed the inner profile in the form of a tube and has an annular cross section.
- the inner profile 20 has a variety of. Stake holes 22, which are essentially in equal distance from each other and with respect to their axes are formed parallel to each other in the inner profile.
- optically acting Deformations are on the outer Circumferential surface of the inner tube 20 optically acting Deformations 24, the outer in the example shown Have the shape of the digits 8 and 9.
- This optically acting Deformations are preferably caused by embossing, i.e. H. one Deformation within the wall of the pipe due to deep Embossing, d. H. a deformation of the wall of the tube, or formed by punching.
- the advantage of embossing or punching the optically acting Deformation lies in the fact that the Production process for the inner profile very simple and therefore can be designed inexpensively.
- the inner profile 20 is preferably formed by that a flat sheet metal strip is deformed into a round tube and along the resulting longitudinal seam is welded. Punching the Holes are made in the flat sheet metal strip, so that the manufacturing the adjustable length support according to the invention additionally the shaping of the optically effective deformations is required.
- optically effective deformations can be done in one common work step, or directly downstream work step, during or after punching the peg holes. This means that the flat sheet metal strip before it is deformed into a round tube and is welded with the punched out holes as well as punched optical markings or with the punched peg holes and embossed optical Markings.
- a rough adjustment of that shown in Fig. 1 adjustable support 10 is made by a provided bolt through the pin hole 22 in Inner profile 20 is inserted and usually against unintentional falling out is secured.

- each have optical markings in the form can be represented by any number Have shape and, for example, different geometric Shapes or symbols such as polygons, circles, ovals, Line markings or the like, but also various Letters or a combination of the above Opportunities.
- FIG. 3 shows a cross section through that in FIG. 2 inner profile 20 shown along the line A-B.
- the The representation scale of FIG. 3 does not correspond to that of FIG. 2.
- the sectional view shown in FIG. 3 becomes clearly that the inner profile 20 from a thin-walled tube exists that has a weld seam 26 in the longitudinal direction. While inside the tube a little There may be weld overhang, the steel pipe planed on the outside so that the weld seam does not protrude forms the outer surface.
- These indentations can, like already explained above, only within the wall of the tube, but also to a deformation of the entire wall thickness of the pipe. That in Fig. 3
- the example shown shows a deep embossing in which the Wall of the tube is deformed. As from the drawing can be seen, forms along the inner circumference of the Pipe an inward bulge 24 of the Inner profile 20, which is characterized by the deep embossing in the form of Number 1 mark formed in Fig. 2 is generated.
- Fig. 4 shows a further embodiment of a adjustable support according to the invention.
- a knurling or corrugation 30 in Longitudinal direction of the inner profile 20 in the area of the optical acting deformations.
- These knurls or Corrugations 30 serve the optical deformations in To emphasize the shape of the embossed digits 24 optically.
- the outer profile is 14 provided with an elongated hole 32 through which the Locking pin it reaches through.
- the elongated hole serves one Fine adjustment using an adjusting sleeve 36 too allow on an external thread of the outer profile 14th is applied and axially displaceable on this.
- the adjusting sleeve 36 becomes axial relative to it
- Outer profile 14 moves, the one on the top of the Adjustment sleeve 36 overlying pins 34 also with this is also moved, whereby a fine adjustment of the Total length of the telescopic support is reached.
- 5a shows a side view of a section of the Inner profile 20 with a pin hole 22 and assigned optically effective deformations 24 in the form of the number 1. How 5a can be seen, they are optical deformations 24 not only directly to the stake hole 22 assigned, but also offset by 90 ° in the same way this. Each in the area of optically effective deformations 24 is a corrugation 30 along the marking 24 of the inner profile applied. This can regardless of Position of the operator the extent of the extension of the telescopic support be clearly recognized from every side.
- Fig. 5b shows a horizontal in the installed position Section through the inner profile shown in Fig. 5a through the Center of the peg hole 22.
- Fig. 5b are the Areas with knurling or corrugation applied as dash-dotted lines shown. These run each time in the area of the pin holes 22 and 90 ° offset to these.
- the width of the knurls or corrugations 30 can be determine the area through the center angle ⁇ is between 10 ° and 30 °, preferably about 20 °.
