  • connection strip according to the invention for ceiling formwork has several spaced-apart coupling areas for engagement with column heads of formwork columns along its length.
  • connection strip according to the invention can be used for ceiling formwork for pouring concrete. But it can also be used for other ceiling formwork, e.g. B. for the temporary undertaking of a ceiling construction for repair work.
  • the connection strip according to the invention can be used to accomplish the connection of a first structure to a second structure during construction work.
  • the first structure can, for. B. be an arrangement of elements of the ceiling formwork

  • connection strip according to the invention can have a plurality of spaced-apart coupling areas for positive engagement with support heads of formwork supports along its length.
  • the form-fitting engagement can be such that it acts in terms of forces essentially in the longitudinal direction of the terminal block; Positive locking with regard to forces acting in other directions can be provided, but does not have to be.
  • the aforementioned, spaced-apart coupling regions include one end coupling region in each of the two longitudinal end regions of the connection strip.
  • the two end coupling areas can, but need not, be the only coupling areas of the terminal block.
  • the connection strip spans the distance between a first formwork prop and a second formwork prop.
  • the respective end coupling area can be designed in such a way that the connection strip in the state coupled to the respective support head either essentially covers only half of the width of the support head - measured in the longitudinal direction of the connection strip - or covers this width of the support head as a whole.
  • the mentioned half-overlap creates an easily practicable possibility of realizing a continuation with a further connection strip in the longitudinal direction of the connection strip.
  • the mentioned full coverage is particularly advantageous if there is no continuation with another connection strip, z. B. because the terminal block is there at the end of a building wall.
  • connection strip between the two end coupling areas has at least one intermediate coupling area for engagement with the prop head of a formwork prop, wherein the intermediate coupling area can, but does not have to have, a design different from the design of the end coupling areas .
  • the connection strip interacts with three or more formwork supports.

  • the mentioned introduction area / receiving area interventions which can be designed as form-fitting interventions, but do not have to, can be implemented in a simple manner during the assembly of the connection strip on the column heads of formwork props.

  • the terminal block according to the invention can furthermore be characterized in that it has, in cross section, one leg that is horizontal in use and one that is vertical in use; and that at least a part of the coupling regions is positioned laterally on the leg which is vertical in use.
  • This basic shape of the connection strip is a good prerequisite for secure positioning of the connection strip on the formwork supports.
  • the terminal block according to the invention can have a main body made of metal, in particular made of aluminum including aluminum alloys.
  • the main body can be a metal extrusion to which other parts are attached.

  • the connection strip is a functional component of the formlining of the slab formwork in use.
  • the top of the connection strip can be equipped with a formwork skin. This can be achieved in that a formlining strip is attached at the top.
  • connection strip according to the invention can have at least one contact area which is provided for contact with a wall, in particular a building wall.
  • connection strip according to the invention can also be characterized in that the distances between the coupling areas are such that engagement with column heads of formwork props is possible, which are at the center distance for the width of ceiling formwork panels.
  • the connection strip embodied in this way through its assembly on the column heads of the respective formwork props, forces the formwork props to be at defined center-to-center distances that correspond to the width of the ceiling formwork panels.
  • the ceiling formwork panels adjoining the connection strip can be set up in a particularly simple manner.
  • connection strip according to the invention can also be characterized in that, when coupled to the respective support head, it essentially covers only half of the width of the support head - measured transversely to the longitudinal direction of the connection strip. This does not rule out that the width measured transversely to its longitudinal extent is greater than half of the mentioned support head width, in which case part of the width of the connection strip protrudes beyond the support head.
  • the so-called "half-coverage" makes it possible to cover the other half of the column head width by the edge area of a shuttering panel or the corner areas of two shuttering panels next to one another.

  • the vertical leg 6 of the connection strip 2 In the direction of double arrow A in Fig. 14 , ie transversely to the longitudinal extension of the connection strip 2, the vertical leg 6 of the connection strip 2 is locked between the positioning extension 72 and the surface of the second wall 54 facing the room.
  • the terminal block 2 more specifically its horizontal leg 4, essentially only covers half the width of the relevant support head 61, 63, 81 - measured transversely to the longitudinal extension of the terminal block 2, so that the other half of this width is covered by an edge region a laid ceiling formwork panel 40 or by two corner areas 90 and 92 of two ceiling formwork panels 40 laid next to one another can be covered.
  • the upper sides of the connection strip 2 and the mentioned ceiling formwork panels 40 lie in a common plane and together form part of a shaping surface for concrete directly adjacent to one another.
  • first support 60 and the second support 62 are equipped with an adjustment option for the height position of the support heads 61 and 63, in the illustrated embodiment by means of an external thread on the upper end area of a lower support section 85, and one with it internally threaded sleeve 82 located in threaded engagement, the upper end face of which acts on a bolt 84 which passes through one of several horizontal bores in an upper support section 86.
  • a height adjustment of the respective support head 61 or 63 by turning the internally threaded sleeve 82 is called "spindles".
  • FIG. 9 The third phase shown in the drawing, two additional supports 80 have been placed between the two supports 60 and 62.
  • the other supports 80 are constructed in the same way like the supports 60 and 62, but without the stand security 64.
  • the support head 81 has been brought into positive engagement with a receiving area 83 with one of the two intermediate coupling areas 22. This engagement is best seen in Figures 16 and 17 .
  • the receiving area 83 used for this intervention is - in the viewing direction of FIG Fig. 17 - Bounded on the left and right by a jaw 85 protruding upwards and, with the exception of its foot area, sloping away to the outside.
  • the receiving area 83 of the relevant further support 80 for the intermediate coupling area 22 of the terminal strip 2 designed as an insertion area is a differently designed receiving area than the receiving area 70 described above for the end coupling area 20 of the connecting strip designed as an insertion area 2.
  • the two further supports 80 are inevitably at a center distance of 1 m between them and the in Fig. 9 right, further support 80 necessarily at a center distance of 1 m to the support 62.
  • the center-to-center distance is somewhat smaller than 1 m (because the connection strip 2 completely covers the width of the support head 61 measured in the longitudinal direction of the connection strip 2).
  • the engagement of the coupling areas 20 and 22 of the terminal block 2 with the four support heads 61, 63, 81, 81 of the four supports 60, 62, 80, 80 assigned to the terminal block 2 enforce or define that the supports are all in the described Center distances.
  • the further supports 80 can each be set up by one person working alone.
  • the other supports 80 are spindled to the correct height.
  • a holding element 86 has been attached to the second wall 54.
  • the holding element 86 has the shape of a substantially vertically extending rail.
  • the holding element 86 has a lug 88 which is displaceable in the longitudinal direction of the holding element 86 and which, in the extended direction, is State goes against the side face of the vertical leg 6 of the terminal block 2 facing away from the second wall 54 (see in particular Fig. 16 ). In this way, the holding element 86 holds the connection strip 2 against the second wall 54.
  • a ceiling formwork panel 40 with two corner areas 90 and 92 is hung on the prop head 61 of the first prop 60 and on the prop head 81 of the further prop 80 adjacent thereto.
  • the four jaws 76 which are present on the side of the respective support head 61 or 81 facing away from the second wall 54, have partial areas that protrude upwards above the level of the support surface 78, and also have points pointing towards the terminal block 2 , small noses 90 each at the top.
  • the corner areas 90 and 92 of the ceiling formwork panel 40 can thus each be suspended in the space between the positioning extension 72 and the upwardly projecting areas of the jaws 76.
  • the corner area 90 occupies the entire width of the prop head 61 - measured in the longitudinal direction of the connection strip 2 - and the corner area 92 only occupies half the width of the prop head 81 - also measured.
  • the suspended ceiling formwork panel 40 initially hangs downward.
  • the ceiling formwork panel 40 with its two other corner areas 94 and 96 is pivoted upwards, with the help of a formwork aid 66.
  • a formwork aid 66 is already in connection with Fig. 7 has been described.
  • the rod-like shuttering aid 66 telescopically consists of two sections which can be displaced relative to one another, so that the effective length of the shuttering aid 66 can be adjusted.
  • the shuttering aid 66 By means of the shuttering aid 66, a working person can pivot the ceiling shuttering panel 40 into an essentially overall horizontal position or beyond it upward.
  • a further support 80 is then positioned at the corner region 94 adjacent to the first wall 52 (as shown in the result in the sixth phase of FIG Fig. 12 ).
  • the prop head 81 of this further prop 80 is designed like the previously described prop heads 61, 63, 81, 81, so that a form-fitting engagement between the corner area 94 and the prop head 81 of the further prop 80 placed last is possible.
  • Fig. 11 one can also see that two further ceiling formwork panels 40 have been suspended from the column heads 81 and 63 of the two further columns 80 and the second column 62, respectively with the two corner areas 90 and 92.
  • Fig. 12 In the sixth phase shown in the drawing, the second formwork panel 40 has been pivoted upwards and a further joint support 80 has been brought into position for the corner area 96 of the first formwork panel 40 and for the corner area 94 of the second formwork panel 40.
  • the further supports 80 of the second column row which is a little more than a formwork panel length away from the second wall 54, are spindled so that the formwork panels 40 of this first formwork panel row are all overall horizontal.
  • the visible partial area of a ceiling formwork which contains four supports 60, 62, 80, 80 next to the second wall 54 and a second row of columns 98 spaced from the second wall 54 in the described manner, and three ceiling formwork panels 40, can continue in the longitudinal direction of the second wall 54 be extended.
  • a support with stability is placed next to the second wall 54, essentially at a distance of the length of a further connection strip 2.
  • the further connection strip 2 in alignment with the connection strip 2 described so far, is placed on two supports in the manner described.
  • the first row of ceiling formwork panels 40 can then be built up further along the second wall 54.
  • the sub-area of the ceiling formwork containing a first row of ceiling formwork panels 40 can also be further built with a second, third, etc. row of ceiling formwork panels 40.
  • the ceiling formwork panels 40 are hooked into the nozzle heads 81 of the second row of supports 80 in the manner described, pivoted upwards and supported with supports 80 at the upwardly pivoted corner areas. In this way you can continue working until the entire slab formwork is completed, if necessary with the help of fitting pieces.
  • connection strip 2 and the described number of coupling regions 20 and 22 of the connection strip 2 are an exemplary embodiment. According to the invention, longer or shorter connection strips 2 are also provided.
  • the number of coupling areas 20 and 22 depends on which ceiling formwork panel widths and for how many Ceiling formwork panels 40, the connection strip 2 is designed. Terminal strips 2 are also possible which have only two end coupling areas 20 and no intermediate coupling area 22, that is to say are designed only for a single ceiling formwork panel width. It is also possible to design connection strips 2 in such a way that the coupling areas have different distances from one another, so that ceiling formwork panels 40 of different widths are connected to one and the same connection strip 2.
  • the edge beam which is assigned to the two corner areas 90 and 92 of the relevant ceiling formwork panel 40, comes to a lower position.
  • the relevant ceiling formwork panel 40 can be pivoted downwards with its two corner areas 94 and 96 without an edge area of the formwork skin of the ceiling formwork panel 40 adjacent to the connection strip 2 digging into the concrete of the poured ceiling from below.
  • the ceiling formwork panel 40 can now be pivoted downward with its corner areas 94 and 96 with the aid of the formwork aid 66.
  • the corner areas 90 and 92 are then unhooked from the column heads 61 and 81, and the ceiling formwork panel 40 is removed.
  • the further supports 80 are removed. For this, their prop heads 81 are screwed down a little. Then the further supports 80 can be conveniently removed. The retaining element 86 is removed. Now the arrangement of the end supports 60 and 62 and the terminal strip 2 stands for itself, and one can easily proceed to the removal of these parts. The prop heads 61 and 63 are screwed down a little. With the help of a shuttering aid 66, the connection strip 2 is removed in the opposite way to that described for erection.
  • connection strip 2 can be combined with many types of column heads, also with other types of ceiling shuttering panels.
  • the connection strip 2 according to the invention can also be used in this environment.
  • the connection strip 2 according to the invention can also be used for ceiling formwork in which one does not want to work with early stripping.
