Definitions

  • the invention relates to a connection formwork for use in the area of the joint between two adjoining concrete slabs which are connected to one another by at least one connecting bolt or mandrel bridging this joint, which is embedded on one side of the joint in the concrete slab there and on the other side of the joint slidably engages in the concrete slab there by means of a sliding guide.
  • the object of the invention is to show a connection formwork which enables the concreting of adjoining concrete slabs in one operation and thus a faster and more rational production of concrete slabs.
  • connection formwork is formed according to the characterizing part of claim 1.
  • Connection formwork in the sense of the invention is to be understood as a lost formwork which already contains all the elements necessary for the formation of the joint between two adjacent concrete slabs, including the at least one connecting bolt and the associated sliding sleeve.
  • the at least one connecting bolt which, like the associated sleeve with its longitudinal extension, is arranged perpendicular to the wall element of the formwork, is used to hold the respectively adjacent concrete slabs together after their completion so that these concrete slabs move in the direction to be able to move the longitudinal extent of the at least one connecting bolt (in the event of temperature fluctuations), but the plates cannot move relative to one another in the direction perpendicular to the at least one connecting bolt.
  • connection formwork In the connection formwork according to the invention, at least two or more than two connecting bolts with associated sliding sleeves are preferably provided.
  • the wall element of the connection formwork according to the invention preferably consists of at least one profile element, which is made from a flat material, preferably sheet steel, by bending and which forms the side of the wall element to which the at least one sliding sleeve is attached. In addition to this profile element, at least one further plate-shaped element is then used.
  • the wall element of the connecting formwork according to the invention is preferably designed such that it has two profile elements made of flat material on both sides of a central plate-shaped element.
  • the legs are provided on the upper and lower longitudinal edge of the wall element and serve on the one hand to support the formwork (legs on the lower longitudinal side of the wall element ) and on the other hand as peel-off edges when concreting the slabs (legs on the upper long side of the wall element).
  • the joint or connection formwork 1 shown in the figures makes it possible to concretely connect two adjoining concrete slabs (for example a roadway, a ceiling, etc.) at the same time, with the formwork 1 producing the joint required between these plates in the connection area.
  • the formwork 1 consists essentially of two profiles 2 and 3, which are each made of sheet steel by bending.
  • the two U-profiles 2 and 3 have the same design in the embodiment shown, ie they each consist of two legs 4 extending in the longitudinal direction of the respective profile and a yoke surface 5 connecting these legs to one another.
  • the width of the latter determines the height of the profiles or profile elements 2 and 3 and thus the height of the formwork 1 perpendicular to its longitudinal extent.
  • the legs 4, each extending over the entire length of the formwork 1, are arranged such that each leg 4 of a profile 2 or 3 lies in one plane with the corresponding leg of the other profile 3 or 2 and the legs 4 on each profile 2 or 3 protrude beyond the side of the yoke surface 5 facing away from the other profile 3 or 2.
  • a plate 6 is arranged, which consists of a suitable, elastic material and whose thickness ultimately determines the width of the joint formed between the adjoining concrete slabs.

With this mounting flange 8 ', each sliding sleeve 8 is attached in the manner described later on the side facing away from the plate 6 of the yoke surface 5 of the profile 3.
  • each connecting pin 10 extends in such a way that it takes up by far the largest part of the length of the body 8 ', but with a distance determining the stretching range from the closed, the profile 3 remote end of the body 8 'ends.
  • Each connecting bolt 10 is also through corresponding openings 11 in the two profiles 2 and 3 or in their yoke surfaces 5 as well as in the plate 6 that it protrudes with a predetermined length over the side of the yoke surface 5 of the profile 2 facing away from the plate 6.
  • a bayonet-type locking mechanism is formed there, namely in that at least two are offset by 180 ° about the axis of the opening 11 Regions 12, the material of the profile element 3 is pressed out or deformed such that the regions 12 protrude beyond the side of the yoke surface facing away from the plate 6, the regions 12 thus form tab-like projections, behind which two diagonally opposite corners of the fastening flange 8 'can snap in .
  • the mounting flange 8 ⁇ is otherwise with its body 8 'facing away from the yoke surface 5.
  • a structural steel fabric 15 formed by a plurality of intersecting structural or reinforcing steels 13 and 14 is fastened in a suitable manner, for example by spot welding.
  • an angled length 15 ' which lies essentially in the plane of the lower leg 4
  • the structural steel fabric 15 stands over the side of the profile 3 facing away from the plate 6.
  • Each in the area of a sliding sleeve 8 is a perpendicular to the longitudinal extension of the formwork 1 structural steel 14 bent at one end up and forms a holder 14 'with this end.
  • a connecting bolt 16 made of plastic is provided, which is arranged with a head 16 'inside the body 8' and protrudes beyond the end of the body 8 '.
  • the bolt 15 is there provided with an opening 17 through which the holder 14 'forming the length of the structural steel 14 extends and in which this holder 14' can be fixed by means of a wedge 18, also made of plastic.
  • the formwork 1 is placed on the base 19, on which concrete slabs are to be erected, in the area of the expansion joint required between two adjacent concrete slabs in such a way that the wall element formed by the yoke surfaces 5 and the plate 6 adjusts the course of the expansion joint between the two adjacent ones Forms plates and the angled length 15 'of the steel mesh 15 is located on the bottom 19.
  • the lower legs 4 form at least part of the footprint of the formwork 1.
  • the upper legs 4 serve as stripping edges when concreting.
  • the formwork 1 with the section 15 ' can be fixed on the substrate 19.
  • the use of the structural steel mat 15 not only enables this fixing, but the structural steel mat 15 also achieves sufficient strength or rigidity for the holder 14 '.
  • Fig. 5 shows in section a joint or connection formwork 1a, which in turn consists essentially of the plate 6 made of elastic material and two wall elements 20 and 21, of which the wall element 20 of the yoke surface 5 of the profile 2 and the wall element 21 of the yoke surface 5 of the profile 3 of the formwork 1 corresponds.
  • the wall elements 20 and 21 are made from flat blanks from a suitable flat material, preferably from sheet steel.
  • these blanks are rectangular blanks which lie with their longer side perpendicular to the plane of the drawing in FIG. 5 and with their two shorter narrow sides in planes parallel to the plane of the drawing in FIG. 5.
