Definitions

  • the invention relates to a formwork for producing beams on concrete ceilings, with two formwork elements arranged at a variable distance from each other, each having an approximately vertical formlining, and with height-adjustable supports for a formwork panel to be arranged horizontally.
  • This formwork should be suitable both for the manufacture of the joists together with the concrete ceiling and for the separate manufacture of joists, for example before the actual concrete ceiling is poured.
  • the formwork for joists to be attached to concrete ceilings was formed from three individual formwork boards, which are held together by clamps encompassing them. Extensive work is required on site to prepare such formwork.
  • the clamps have to be installed close to each other and are usually mounted on beams that run parallel to the joists and also serve as formwork beams for the ceiling formwork. Before shuttering, the clamps must be adjusted to the cross-sectional dimension of the beam in question.
  • the invention has for its object to provide an easy-to-use, consisting of only a few parts joist formwork, which does not require special beam yokes for hanging and which can be easily adjusted or adjusted to the desired cross-section of the joist in the working position.
  • the invention creates a beam formwork that is self-supporting and therefore does not require any specially designed beam yokes for hanging. Rather, the joist formwork according to the invention can be supported directly on the floor, i.e. it can be placed on the usual tubular steel supports without the need for intermediate beams.
  • the sides of the formwork consist of finished self-supporting formwork panels, which can be assembled in any length from individual panel pieces, while for the Ab support the horizontal lower formwork panel in height adjustable supports are provided by means of a grid.
  • the connecting elements holding the individual lateral formwork panels together are preferably designed as a frame, the frame being provided with sliders which can be adjusted on it and to which adjacent panel elements are fastened.
  • the distance between the side formwork elements or formwork panels can be changed without having to make any changes to the support itself, because each frame rests with its two outer ends on tubular steel supports, the mutual spacing of which need not be changed, if you adjust the slider on the frame.
  • an adjustment of the cross-section of the girder to be produced with the girder formwork according to the invention is also still possible when the girder formwork is already in the working position.
  • the height of the lower formwork panel of the formwork can also be changed or adjusted at the place of use, simply by repositioning the supports provided for its support.
  • the joist formwork according to the invention therefore does not need to be preassembled outside the place of use and then brought to the place of use by means of a lifting device. Rather, you can bring the few individual parts of this joist formwork directly to the place of use and only then assemble and bring them into the desired mutual position.
  • the frames are first placed on tubular steel supports and then the side formwork parts or formwork panels are attached and brought to their desired mutual distance before the horizontal formwork panel is inserted as the last assembly step. The procedure can be reversed when stripping. Since no additional formwork beam yokes are required to support the joist formwork, the joist formwork according to the invention differs fundamentally from the known prior art.
  • two frames are first set up on four tubular steel supports at the desired height, whereupon the side formwork elements or formwork panels are hung between these two frames. Then the joist formwork is extended by attaching additional formwork panels in the free stem until the desired length is reached. Finally, the horizontal lower formwork panels or floor panels are inserted. The formwork is removed in the reverse order, with the individual components of the formwork being able to be reassembled to form a new joist formwork elsewhere after cleaning. You don't need a crane to do this is available for other work. If the crane is free, it can of course also be used for the transport of the individual elements of the beam formwork according to the invention.
  • bars are used as lateral Schalelemte together with the frame parts.
  • This embodiment is preferably used in the compensation area, ie only where the angular side formwork panels of the above-described embodiments do not fit due to their length.
  • the formlining is formed from formwork panels and squared timbers.
  • this embodiment can also be used as an independent joist formwork wherever the use of formwork panels is dispensed with.
  • the frame parts together with the vertically arranged bars take over the support function for the formwork skin materials to be installed at the construction site instead of formwork panels.
  • a side switch panel 1 of the girder formwork is shown, which consists of a skeleton frame 2 made of aluminum profile and has a formwork skin 3 that is protected on all sides are.
  • reversible supports 6 serve to support the lower formwork panel forming the bottom of the beam formwork.
  • the formwork panels 1 are held together, for example, by means of frames 7, one of which is shown in FIG. 2.
  • This frame 7 is equipped with a total of four sliders 8 adjustable on it.
  • Each slider 8 contains openings 9 for inserting the clamping bolts 5
  • Formwork panels 1 and can be pinned by means of a plug pin 10 in a hole pattern 12 on the frame spar 11, on which it can be moved.
  • the upper spar 11 of the frame 7 is provided at both ends with an outwardly projecting extension 13, on the underside of which there is a pin 14 which fits into the central opening on the head part of a steel pipe support.
  • Fig. 3 it can be seen how the two side formwork panels 1 are braced with a frame 7 by means of the clamping bolts 5 via the slide 8.
  • the free space 15 of the formwork provided for producing the girder has the height H and the width B.
  • the width B can be changed by means of the hole pattern 12, simply by pulling the plug pin 10 and moving the relevant slider 8 over a suitable hole in the hole pattern 12 and then inserting the plug pin 10 again.
  • the height H can be changed by repositioning the supports 6 in the grid 17.
  • the height of the lower formwork plate 16 also by different thickness, longitudinally or transversely arranged documents 18 between the individual public Solutions 19 of the grid 17 can be adjusted. Only when the thickness of the base 18 should correspond to the distance between two holes 19 is the support 6 repositioned, so that its plug pin 6a is in the next hole 19. Near the lower end, the support 6 is provided with a centering pin 6b which can engage in a deeper hole 19 of the hole pattern 17 in order to prevent the support 6 from tipping over.
  • the vertical bar 20 shown in FIG. 5 in two views offset by 90 ° to one another has a short arm 21 and a longer arm 22, which are each provided with fastening plates 23.
  • the bolt 20 In the angled node area 24, the bolt 20 has bearings 25.
  • compensating lengths can be bridged when formwork is being used, just as it is possible to construct under-beam formwork of any cross-section using construction site means.
  • Fig. 6 shows the practical use of the bolt 20 of one of the formwork Unterzu g- in bridging of g seeks to length 27.
  • the formwork surface 28 to be compensated is formed by a formwork skin 29 cut at the construction site and by means of squared timbers 30 which are attached to the fastening plates 23, so that the whole is supported by bolts 20.
  • Through the openings 26 of the lower arms 21 and 22 of the latch 20 are
  • the adjoining panel 1 is attached on the other side of the slide 8 by means of the bolt 4 located there.
  • the frames 7 are supported with the extensions 13 of the upper spars 11 on tubular steel supports 32.
  • the short arm 21 of the latch 20 carries the formwork skin 29, while in the cross section 34 shown on the right in FIG. 6 the long arm 22 of the latch 20 points upwards and accordingly the short arm 21 carries the connection to frame 7.
  • Figures 7 to 9 show the structure of the beam formwork in the free porch.
  • two frames 7 are arranged on tubular steel supports 32, each of which is provided with a support frame 35.
  • Fig. 8 shows that the next frame 7 is then attached and supported on simple tubular steel supports 32.
  • the support frame 35 can be implemented to stabilize the side of the new steel pipe supports.
