Definitions

  • the invention relates to a ceiling switch table arrangement according to the preamble of claim 1.
  • Such ceiling switch table arrangements are available in different versions known (DE-OS 26 48 281; DE-OS 29 00 305; DE 38 43 336 C1).
  • the main problem with such ceiling switch table arrangements consists in the fact that the supports are largely rigid on the one hand connected to the support frame stiffening the ceiling switch table must be, but on the other hand after dismantling the supports from the ceiling control table, if possible, no components below from the ceiling control table should be in order to be transported by truck or by the Storage of a small stack height of several stacked table tops to reach.
  • a generic ceiling switch table arrangement is from DE-OS 28 24 106 known. With it, the joint sleeves are above the counterpart support piece support plate downwards, to which the Transition support piece support plate of the supports is attached.
  • the aim of the present invention is a ceiling switch table arrangement to create the genus mentioned, in which the unfolded and supports that support the overhead formwork table are particularly resistant to bending connected to the ceiling control table or its support frame are, at the same time a space-saving stackability of several ceiling switch tables is guaranteed.
  • the support plates by means of appropriately stable intermediate components Ultimately, it can be fixed to the support frame of the ceiling control table or connected to the components attacking the upper end of the supports is the mutual hanging and locking the support plates achieved extremely high rigidity.
  • the minimum stack height of the ceiling formwork tables designed according to the invention is both simple hanging and swiveling the supports are possible without any problems, and it will also be locked optimal bending rigidity guaranteed.
  • the training according to the invention also allows two yoke beams to be arranged close together and assign a single counter-support piece to these double beams.
  • transition support is preferred primarily firmly connected to the upper area of the supports, so that in general Existing head plate of the supports only secondary at most is involved in the rigid mounting of the supports.
  • the provision of the actuating lever according to claim 10 has the advantage that the unlocking from below by means of a rod or the like can be done by simply moving the operating bracket is pushed up.
  • the locking can expediently simply done by the fact that the operating bracket due to the Weight force swings down and thus engages the locking lever the associated support plate brings.
  • the hooks on the upper support plate and the hook counter bearings are preferred attached to the lower support plate as in claim 11 is defined.
  • the counter-supports can be attached to numerous different Positions between cross beams are attached. Likewise, those with the mounting brackets to form a frame on any Places between two adjacent cross beams, so that the counter-supports practically at any desired location can be attached to the underside of a ceiling control table.
  • the supports usually have top plates at the top and bottom.
  • the upper head plates on the underside of the support plates of the transition support piece issue.
  • the head plates accept this way a rigid mounting of the supports without being overloaded become.
  • the embodiment variant according to claim 16 can achieve that when pivoting the supports from the tilted, suspended position in the working position of the locking process automatically is possible.
  • the locking lever can automatically in the locking position grab.
  • a ceiling formwork table 13 consists of a formwork skin 42 the underside of which is arranged parallel to one another at the same distance Cross members 33 and below the cross members 33 perpendicular to them arranged yoke beams 34, each of two closely side by side arranged individual carriers can exist. That way a stable one, also suitable for taking up large quantities of concrete Ceiling switch table 13 formed.
  • the ceiling control table 13 is not supported by four at the bottom on one shown document standing telescopic supports 11, the bottom and top completed by head plates 39 running perpendicular to the column axis are. In their upper end region, the supports 11 are fixed to one Transition support piece 12 connected, which in turn on a counter-support piece 14 is releasably attached, which by means of support elements 31 and Support beam 32 between the cross beams 33 and the yoke beams 34 so is arranged and braced that it is an integral part of the ceiling switch table 13 forms.
  • two supporting beams 32 are parallel to each other attached to mounting tabs 35 extending perpendicular to them.
  • the length of the support beam 32 or the distance between the two Support beam 32 to a support frame 41 supplementary connecting straps 35 is such that it corresponds to the distance between two cross members 33, so that the support frame 41 according to Figure 7 just between two adjacent Cross member 33 fits and on this above the yoke member 34 by means of Bores 43 and screws, not shown, can be attached.
  • Prefers are the connecting tabs 35 in the manner shown Angle profiles formed, one leg of Figure 7 on the lower Spar 44 of the cross member 33 can rest, making a flawless and particularly stable mounting of the support beams 32 on the cross members 33 is guaranteed.
  • the support beams 32 themselves are designed as U-profiles which are open to one another and have several continuous mounting holes at regular intervals 36 on.
  • FIG. 3 that which is to be fastened at the bottom to the supporting beam 32 according to FIG Counter-support piece 14 is shown, which - as is also shown in FIGS up to 7 - from a flat, horizontal counterpart support plate 16, two of whose long sides project vertically upward Cheeks 19 and support elements projecting vertically upwards 31 exists, which in turn by a lower T-profile 38 and each at their vertical end 37 fasteners are formed, which in later assembly according to Figures 5, 6 and 7 in each a pair of superimposed holes 36 of the support beam 32 are introduced, whereupon according to Figure 7 on the above with thread provided bolts 37 bracing nuts 45 are screwed on.
  • the Bolts 37 must therefore be threaded at least in their upper end region be provided.
  • the cheeks 19 are in the manner shown in FIGS. 3, 5 and 6 formed in the manner of a flat triangle with a rounded top and point to them in the area of the short sides of the support plate 16 ends located essentially upwardly extending hooks 17 on.
  • the support plate 16 extends on both sides approximately up to Height of the hook 17 and has right next to the hook 17 Cutouts 23 on.
  • the T-profiles 38 are vertical on the central transverse axis 21 of the support plate 16 arranged, in such a way that the T-center bar on the inside the cheeks 19 abuts and is welded there.
  • Below are the profiles 38 on the support plate 16 and are also preferably welded there.
  • the crossbars of the T-profile 38 face each other and parallel to each other. Their distance is chosen so that there is a straight line between them a double yoke support 34 fits, as can be seen in FIG. 1. Due to the design described, the counter support piece 14 1 pushed onto a double yoke support 34 from below be, the vertical support members 31 between two cross members 33 protrude upwards, where a support frame 41 according to FIG. 2, 7 is fastened, the bolts 37 pass through two of its pairs of bores 36. The distance between the support beams 32 of the support frame 41 thus corresponds the distance between the bolts 37.
  • a bracing nut 45 is placed on the bolts 37 from above screwed.
  • the counter-support plate 16 of pulled below against the double yoke beam 34 and firmly clamped against it.
  • the crossbars of the profiles 38 are laterally on the yoke beam 34 at.
  • the arrangement carries out Support frame 41 and counter-support member 14 also essential for stability of the lower frame of the ceiling switch table 13.
  • the counter-support 14 practically only the thickness of the counter-support plate 16 down over the yoke beam 34 stands out. Since the thickness of the support plate 16 is only about 8 mm, is the protrusion downwards over the ceiling control table 13 practically negligible.
  • the cheeks 19 including the hooks 17th extend from the support plate 16 only upwards and not downwards protrude.
  • Figure 4 shows the transition support piece 12, which according to Figure 1 is firmly connected to the upper end portion of a support 11 and is designed so that it with the counter-support piece 14 after Figure 3 can be releasably connected from below.
  • the essential part of the transition support piece 14 is a horizontal one flat support plate 15 of a thickness of about 6 mm, which is somewhat wider and shorter than the counter-support plate 16 of Figure 3 is. Cheeks 20 are on the long sides of the support plate 15 turned above. The distance between the cheeks 20 is chosen so that when Applying the transition support piece 12 to the counter support piece 14 Cheeks 20 according to Figures 5, 6 on the outside of the triangular cheeks 19 of the counter-support piece 14 come to rest. The cheeks are 20 much lower than the cheeks 19 and have a parallel to the plane of the support plate 15 extending upper edge 20 '.
  • the lower support plate 15 has only one end a pair of hook counter bearings 18. Between the diagonally upwards bent tabs 22 and the associated cheeks 20 is located below the hook counter-bearing 18, a slot 46, the size of which is so dimensioned is that a hook 17 can be inserted there.
  • a holder 29 is preferably attached by welding, which has essentially U-shaped horizontal cross sections.
  • the holder 29 On his closed side, the holder 29 has a vertically extending prismatic Indentation 47 of such dimensions that supports 11 differ Cross-section (round, angular) and different dimensions can be included in it.
  • two clamps 30 arranged one above the other are provided, which by only indicated bolts 48 (see also FIG. 6) the upper one used Can clamp the end region of a support 11 against the recess 47, so that the holder 29 practically an integral part of the support 11th forms.
  • the clamps 30 are also designed in their cross section so that they support different cross-sectional shapes and sizes on the holder 29 can set.
  • two locking levers 24 can be pivoted about a transverse axis 26 arranged, which above the pivot axis 26 each have a latch 25, the locking lever pivoted up 24 overlaps the support plate 15, as can be seen in FIG. 4.
  • the two locking levers 24 are located on the other side of the transverse axis 26 around the holder 29 extending actuating bracket 27 fixed connected with each other. In this way, the weight of the Actuating bracket 27, the locking lever 24 in the one shown in Figure 4 Position pivoted, if the transition support piece 12 as in Figure 4 is shown, is arranged vertically.
  • the latches 25 have a snap-in bevel 40, the Meaning is explained below. It is important that the locking lever 24th by any restoring force, which is also provided by a restoring spring Can be made available, in each case to that shown in Figure 4 Lock position to be biased.
  • the dimensioning of the individual components of the transition support piece 12 can be found in the following functional description.
  • the already with the support frame 41 and the counter-support pieces 14 provided ceiling switch table 13, for example, by a Crane held at a certain height that is greater than the length the supports to be attached 11.
  • an operator can each have a top with a transition support Take 12 provided support 11 in hand and at more or less inclined support 11 the hook counter-bearing 18th lead over a pair of hooks 17 of the counter-support piece 14, the Pass the hook 17 through the slots 46 (FIG. 4). Once the hook 17 are passed through the slots 46, the operator relieve the relevant support 11 somewhat, whereupon the Hook counter bearing 18 in the recess located behind the hook 17 49 ( Figure 3).
  • the supports 11 are released from the ceiling formwork table 13 in that for example by means of a rod of the actuating bracket 27 (FIGS. 4, 5, 6, 7) is pushed up, causing the latch 25 from the top Release support plate 16. Then the support 11 can then the pair of hooks 17 are pivoted to which the lower one Support plate 15 is attached. The locking lever 25 are down pivoted and thus completely disengaged from the upper Support plate 16.
  • the supports 11 can now be pivoted into the horizontal for transport must, however, if they are at the overhead table during transport 13 should remain, in a suitable manner on the ceiling control table 13 are attached so that the hook counter bearing does not unhook 18 from the hook 17.
  • the supports 11 are separate from Ceiling switch table 13 can be transported, as is preferred simply unhook the hook counter bearing 18 from the hook 17.
  • the ceiling formwork tables with practically none Overhang of components down for transport to Available. Because there is no protrusion of the counter supports 14 down can thus a minimum stack height when Transport can be achieved.
  • the high rigidity of the arrangement of the supports 11 on the ceiling formwork table 13 is primarily due to the close contact of the support plates 15, 16 achieved, of importance also by the Training brought about positive contact between the transition support piece 12 and counter-support 14 is.
  • the lateral form closure of the two support plates 15, 16 is due to the abutment of the cheeks 19, 20 reached during the positive engagement in the longitudinal direction by the attack the hook 17 on the hook counter bearings 18 and the system of Bottom of the groove 54 ( Figure 5) between the locking lever 24 and the latch 25 on the opposite edge 50 ( Figure 3) of the support plate 16 is reached.
  • the invention ensures thus not only an easy to assemble and easy to remove and special rigid arrangement of supports 11 on the ceiling control table 13, but also an extremely universal use for a wide variety of types of supports 11 and ceiling formwork tables 13.
  • the Support plates 15, 16 are relatively large. Your dimensions can e.g. about 15 cm x 25 cm.
  • the width of the support plates 15, 16 is ultimately predetermined by the width of the double yoke beam 34 largely standardized in the formwork techniques in question and are standardized.
  • Support plates 53 may be arranged with the support plate 15 or the holder 29 are welded. As a result, the rigidity of the arrangement further increased.
