Definitions

  • Length adjustable supports for concreting formwork are known in many types and on the market.
  • the support has a first pillar portion having a hollow cross-section at least in part of its length, and a second pillar portion telescopically slidably seated in the first pillar portion with a portion of its length.
  • a nut is attached so that it can be rotated but does not make relative movement relative to the first pillar portion.
  • the nut possesses on an axial Part of its length an internal thread which is in engagement with an external thread on the second support portion. As a result of rotation of the nut, the second support section can thus be moved further into the first support section or continue out of the first support section.
  • the invention has for its object to provide a length-adjustable support for concreting or for scaffolding in construction, which can be extended in a convenient manner to the particular desired length of use and thereby allows a precise fine extension and fine retraction.
  • both the coupling sleeve and the adjusting sleeve can, if desired, be carried out very easily with one hand. But you can also work, especially in the adjustment sleeve, with two hands and / or with a torque arm raising the applied torque.
  • the first support portion may be profiled at least in the said part of its length on the inner circumference and the second support portion in said part of its length on the outer circumference and corresponding to each other, that the second support portion is held rotationally relative to the first support portion. This makes the handling of the support particularly uncomplicated.
  • the first support portion distributed at least in part of its length around the outer circumference having an alternating sequence of longitudinal grooves and longitudinal elevations.
  • a lateral longitudinal gutter undercut can be formed.
  • the second support section may have a plurality of longitudinal elevations distributed over the outer circumference over at least part of its length. It is possible to make the embodiment such that the longitudinal elevations of the second pillar portion respectively project into an inside longitudinal groove of the first pillar portion which are respectively located at those positions where there are longitudinal elevations outside the first pillar portion. This is one of the ways in which the previously described, rotationally fixed holding of the second support section relative to the first support section can be carried out.
  • the externally threaded portion of the first support portion and / or the circumferentially extending ribs and / or grooves of the second support portion may each consist of a plurality of, over Scope distributed sectors be constructed. These sectors can be assigned to the longitudinal elevations on the outer circumference of the first support section and / or the longitudinal elevations on the outer circumference of the second support section. In this way, the production of the externally threaded section on the first support section and / or of the ribs and / or grooves on the second support section, which frequently takes place in a chip-making manner, is simplified.
  • the at least one, extending in the circumferential direction groove and / or rib of the coupling sleeve can be constructed of a plurality of sectors distributed over the circumference.

  • the coupling sleeve and / or Verstellmuffe consist of two halves, which are joined together at a running in the axial direction of the coupling sleeve or Verstellmuffe dividing plane.
  • This split design results in easier manufacturability of these sleeves, be it in particular when produced by cutting production or, in particular, when produced by injection molding or die casting.
  • the coupling sleeve may have at least one latching element, which cooperatively with a counterpart on the second support portion, the coupling sleeve releasably in a rotational angular position relative latched to the second support portion, in which said engagement with the ribs and / or grooves of the second support portion consists.
  • This facilitates the operation of the coupling sleeve, because the worker senses whether or not the coupling sleeve is in engagement with the ribs and / or grooves of the second support section.
  • unintentional disengagement with the ribs and / or grooves of the second support portion is more reliably avoided.
  • said engagement between the coupling sleeve and the Verstellmuffe may be formed by an annular groove / annular rib engagement. This is favorable in terms of production and can be realized in a particularly simple manner, in particular in the case of the above-mentioned split design of coupling sleeve and / or adjusting sleeve.
  • the internal thread of Verstellmuffe may be locked at the coupling sleeve opposite end against threaded engagement with the male threaded portion of the first support portion.
  • the barrier are radially inwardly leaking thread in front of said, opposite end of Verstellmuffe, or small grub screws, which screws into the respective end portion of the internal thread.
  • the locked in the end region female thread leads to the fact that you can not separate the Verstellmuffe towards the second support section from the first support section by unscrewing, not even unintentionally.
  • a first end component of the support be releasably secured.
  • a second end component of the support releasably secured be.
  • the support according to the invention which has the features of one or more of the above-mentioned embodiments, in the vast majority, substantially vertical or obliquely from top to bottom applications either with the "first support section below” or with the “second support section below "be used. Even in essentially horizontal applications, in most situations it does not matter which column end you take to the left and which column end you take to the right.
  • first component may have a hollow portion with an internal thread, which is in engagement with a further male threaded portion on the first support portion.
  • second support section second end component may have a hollow portion with inside at least one, extending in the circumferential direction groove and / or rib, which extends over only a portion of the circumferential length and at each appropriate rotational position of the head component relative to the second support portion is either in engagement or out of engagement with said ribs and / or grooves of the second support portion.
  • This hollow region can be constructed like the inside of the coupling sleeve.
  • the hollow portion of the head or foot component may also have one or more of the "optional features" disclosed in this application in the context of the coupling sleeve.
  • the first end component or the second end component may be a top component for co-operation with longitudinal beams of a concrete slab formwork, or a head component for co-operating with formwork slabs of a concrete slab formwork, or head stock for co-operation with side beams and / or formwork panels of a concrete slab formwork, or a head stock for angled connection to a concreting wall formwork.

  • the first support section 4 is hollow tubular and has four longitudinal elevations 20 distributed over its circumference and thus alternately four longitudinal grooves 22. At each transition from longitudinal elevation 20 to longitudinal channel 22, a lateral longitudinal gutter undercut 24 is formed. At those positions where there are longitudinal elevations 20 on the outside, longitudinal grooves 26, ie local radius enlargements, are present on the inside.
  • the outside longitudinal elevations 20 are bounded radially on the outside each by a circular arc
  • the outside longitudinal grooves 22 are radially outwardly bounded in each case circular arc
  • the inside longitudinal grooves 26 are radially outwardly bounded in each case arcuate, between the inside longitudinal grooves 26, the inner circumference of the first support section 4 in each case according to a circular arc limited outside.
  • the outer longitudinal elevations 20, the outer longitudinal grooves 22, the undercuts 24 and the inner longitudinal grooves 26 each extend over the entire length of the first support section 4.
  • the execution of the first support section 4 need not necessarily be so. You could z. B. only one in Fig. 1 Forming the upper part of the length of the first support portion 4 in this way.
  • the second support section 6 is also formed hollow tubular.
  • the cross section of the second support section 6 is bounded on the inside by a full circle.
  • the outer longitudinal projections 30 of the second support section 6 extend over its entire length.
  • the formation of the second support section 6 does not necessarily have to be this way.
  • Fig. 2c is easy to see how a partial length of the second support section 6 is telescopically received in the interior of a partial length of the first support section 4.
  • the longitudinal elevations 30 of the second support portion 6 fit with some play in the circumferential direction and with a slightly larger clearance in the radial direction in each case in an inner longitudinal groove 26 of the first support portion.
  • the second support section 6 - apart from the mentioned, small game in the circumferential direction - rotatably held in the first support section 4, but can be moved telescopically in the axial direction relative to the first support section 4.
  • the described embodiment further ensures that - apart from the described, small, radial clearance - the second support section 6 is coaxially held and guided in the first support section 4.
  • Fig. 3 It can be seen clearly that in each case an external thread section 34 is provided in the first support section 4 both in the upper end region and in the lower end region. Both externally threaded portions 34 are formed the same, so that only the upper one is considered in the following description.
  • the male threaded portion is divided into four sectors distributed over the outer circumference of the first pillar portion 4. These four sectors 36 are each assigned to an outer longitudinal elevation 20 of the first support section 4.
  • Fig. 3 is the length of the first support section 4 against the reality (as in Fig. 1 drawn) shortened.
  • the longitudinal elevations 30 have been machined so that an axially successive row of grooves 38 has been formed on each longitudinal elevation 30.
  • Two adjacent grooves 38 are separated from each other by a radially outwardly projecting rib 40.
  • the grooves 38 and the ribs 40 extend in the circumferential direction of the second support portion 6 and have no pitch when moving circumferentially along the grooves 38 and ribs 40.
  • the training does not necessarily have to be this way, you could z. B. allow a small slope, but would have to provide increased security against unwanted twisting of the coupling sleeve 8 relative to the second support section 6.
  • Whether one speaks of grooves 38 and / or ribs 40 is a matter of the reference surface. If one takes the outer radius of the longitudinal projection 30 as a reference plane, one has only grooves 38 and no ribs 40. If one takes the bottom of the grooves 40 as a reference surface, one has only ribs 40 and no grooves 38th
  • the coupling sleeve 8 is a total - roughly speaking - hollow-tube-like and consists of two practically identical halves 8a and 8b, which are joined to a running in the axial direction of the coupling sleeve 8 dividing plane 42, z.
  • Positioning pins 46 projecting into locating holes 48 in the other coupling sleeve half ensure accurate mutual positioning of the halves 8a and 8b.
  • the coupling sleeve 8 has - with the exceptions to be described below - a cylindrical inner surface. At four positions, which are distributed circumferentially about this inner circumference 50, there is a respective rib group 52. Each rib group 52 contains - in an axially extending row - three ribs 54 which are axially spaced apart from one another, to be described below. The ribs 54 extend in the circumferential direction and have no slope. The ribs 54, when measured in the axial direction, are so wide that each rib fits into a groove 38 of the second support section 6 with little play. The mentioned distances between the ribs 54 are so large that in each case with a small clearance a rib 40 of the second support section 6 fits.
  • the spacing spaces 56 between the ribs 54 could also be referred to as grooves.
  • ribs 54, grooves 56 and reference surface for the terms ribs and grooves the same applies, which has been said above in connection with the grooves 38 and ribs 40 on the second support portion 6.
  • the ribs 54 are sharpened so that they easily slip into three grooves 38 on the second support section 6 upon rotation of the coupling sleeve 8 relative to the second support section 6.
  • the ribs 54 are as it were connected by an axially extending web 58 with each other.
  • the clearance spaces / grooves 56 between the ribs 54 do not pass over the entire circumferential length of the ribs, but rather in front of, at the top in FIG Fig. 4 right, end of the ribs 54 stop.
  • the axially continuous ridge that closes the spacing spaces 56 at one end is to limit the rotational movement of the coupling sleeve 8 relative to the second pillar portion 6 counterclockwise when viewed from the top of the coupling sleeve 8 as soon as the ridge 58 abuts against the circumferentially facing end faces of ribs 40 on the second support portion 6.
  • the ribs 54 are so long that the rib group 52 fits with play into a circumferential spacing space 60 between two outer longitudinal elevations 30 (with the grooves 38 and the ribs 40). If all four rib groups 52 are each located in a clearance space 60, the second support section 6 is decoupled with respect to axial relative movement relative to the first support section 4 and can therefore either freely pushed further into the first support section 4 or pulled further out of the first support section 4 become. In contrast, when the coupling sleeve 8 is rotated about 45 ° relative to the second support portion 6, the ribs 54 come into grooves 38 of the second support portion 6. The second support portion 6 is coupled to the coupling sleeve 8 - in terms of axial relative movement.
  • the four rib groups 52 are uniformly distributed in the circumferential direction over the inner surface 50 of the coupling sleeve 8, so that the four Rib groups 52 are all at the same time either engaged with corresponding grooves 38 and ribs 40 or are out of engagement with the second support portion 6 because they are positioned in the clearance spaces 60.
  • the described function of the coupling sleeve 8 can also be achieved if, instead of the rib group 52, only a single rib 54 is present which, with a corresponding rotational position of the coupling sleeve 8, comes into only one groove 38 of the second column section 6.
  • the number of ribs 54 per rib group 52 is determined according to practical design considerations. Numbers other than three ribs 54 per rib group 52 as provided in the illustrated embodiment are possible.
  • a latching element 61 is present.
  • the latching element 61 is formed in the manner of a circumferentially extending leaf spring, which at its in Fig. 4 left end carries a radially inwardly projecting catch 62, which - viewed in axial plan view - is chamfered on both sides to the radially inner end.
  • the latching element 61 has the same radial thickness as the main portion of the coupling sleeve 8.
  • the resilient portion 64 of the latching element 61 goes to its in Fig. 4 right root integrally into the remaining coupling sleeve 8 via.
  • Axially above and axially below the resilient portion 64 is a gap to the remaining material of the coupling sleeve. Also in Fig. 4 in the circumferential direction to the left there is a distance between the catch 62 and the remaining material of the coupling sleeve. In this way, the catch 62 can move resiliently a bit radially outward compared to the drawn situation, until the addressed tip / end of the catch 62 substantially has come to the level of the inner surface 50 of the coupling sleeve 8.
  • the latching element 61 is positioned with its catch 62 in such a way that, when viewed from the disengaged position, viewed axially from above, the coupling sleeve Fig. 4 counterclockwise - rotates into the engaged position, the catch 62 then in the circumferential direction "behind” an outer longitudinal projection 30 of the second support portion 6 resiliently radially inwardly into the in Fig. 4 drawn position moves, so "circumferentially behind" this longitudinal survey 30 snaps.
  • the tip of the catch 62 on the radially outer side of one of the ribs 40 of the second support portion 6 had slid circumferentially along, which was possible by spring-out radially outward.
  • the design can be made such that the catch snaps "behind" the other end of the respective rib 40 as soon as the respective rib group 52 is out of engagement with grooves 38 / ribs 40 of the second support section 6.
  • the equipment of the coupling sleeve 8 with at least one latching element 61 has several advantages. On the one hand, there is greater certainty that the coupling sleeve 8 is accidentally turned to the disengaged position. On the other hand, the worker feels with a "click-feel" when he has the coupling sleeve 8 correctly turned into the engaged position or in the disengaged position.
  • latching element 61 in the manner of a leaf spring 64 and a catch 62, both z. B. integral with the remaining coupling sleeve 8 and z. B. plastic, is only one of the possibilities for realizing the Verrastungselement 61.

  • a typical example is empty scaffolding under bridge arches or in churches, if you have to perform work from the inside at the church ceiling. But you can also represent other types of scaffolds using inventive columns, z.
  • a "slice" 132 of a scaffold is shown.
  • One or more further discs 132 close at a distance in front of and / or behind the plane of the drawing.
  • the drawn disc 132 consists of two successive columns 2 left, two successive columns 2 right, and crossbars 134 between them.
  • the head component 14 of the lower support 2 is connected to the foot component 12 of the upper support 2, z. B. by means of bolts that go through the base plates 80 and 82.
  • the cross bar 134 which are each constructed in the manner of a truss, are formed at both ends so that these ends can reach into the outer longitudinal grooves 22 of the first support sections 4 and are held there because of the above-described undercuts 24 against lateral withdrawal.
  • On the uppermost cross bar 134 of the disc 132 may be placed on a floor covering of plate-like or screed-like elements.
  • the supports 2 Due to the length adjustability of the supports 2 according to the invention can compensate in particular uneven floors, so that the whole overhead column ends lie at least for a part number of the total columns in a common plane; The same applies at least for a number of parts of the crossbars 134. Furthermore, you can adjust the height level on which the very top end of each overall support, by means of the coupling sleeves 8 and the adjusting sleeves 10 exactly what z. B. is advantageous if the framework above a formwork z. B. should wear for a bridge arch.
  • Drawn scaffold plate 132 differs from that in Fig. 11 Drawn scaffolding plate 132, characterized in that instead of two, aligned with each other, first support sections 4 has provided an approximately twice as long, first support section 4. In this long, first support section 4, a second Staueraffabschitt 6 is telescopically inserted from below, and in the upper end of the first support section 4 from the top another, second support section 6 is telescopically inserted.
  • FIG. 13 illustrated hall 136 is constructed with two stands 132, of which each one frame 132 extends along a longitudinal boundary of the hall 136. In Fig. 13 you can see a "slice" of each frame 132. Further discs close in front of and behind the plane of the drawing.
  • the frameworks 132 have the same structure as those in FIG Fig. 11 drawn and described there framework 132. For the use of cross bars 134 that applies in connection with FIGS. 11 and 12 Said.
  • an inverted V-shaped roof construction 138 is placed on top of the scaffolds 132.
  • the four "hall walls” may be open or closed by panels inserted into the frameworks 132 or otherwise.
  • a grandstand 140 is drawn in horizontal view. Shown again is a "disc” of the grandstand 140, with more discs in front of and behind the plane of the drawing. It can be seen that the staircase-like structure of the grandstand 140 can be created with the supports 2 according to the invention in a particularly simple manner.
  • tribune 140 in turn cross bar 134 at appropriate locations in the plane of the disc and at right angles to this from support to support 2 are present.
  • a trench shoring 142 is shown in Fig. 15 .
  • a trench 144 extends in the soil 146, with the longitudinal extent of the trench 144 being at right angles to the plane of the drawing.
  • Down in the trench 144 is a sewer pipe 148th
  • the Grabenverbau 142 has as main components a strong, in Fig. 15 left plate 150 and a strong, in Fig. 15 right plate 152 on.
  • the plates 150 and 152 measured at right angles to the plane of the drawing, have a length of a few meters.
  • the trench structure 142 can be moved downwardly into the earth at a reduced spacing of the plates 150, 152 stepwise and in accordance with the progress of excavation of the trench 144, and can then be moved out of the first through the second support section 6 respectively Support section 4, and thus a moving apart of the plates 150, 152, the trench extension 142 with its plates 150, 152 press against the trench walls.
  • each of the Wenn istteil 12 and the head component 14 were provided in a longitudinally split design. It is emphasized that it is particularly the foot component 12 and / or the head component 14 alternatively in undivided Can realize performance. This is due to the absence of annular groove 70 and annular rib 72 (as described in connection with coupling sleeve 8 and adjusting sleeve 10, see Fig. 4 ) is even less problematic than in the coupling sleeve 8 and the adjustment sleeve 10.
