Definitions

  • the invention relates to a connection formwork for use in the area of the joint between two adjoining concrete slabs.
  • connection formwork which consists of a wall element which, with its thickness, determines the width of the joint.
  • the sliding sleeves are attached to one side of this wall element.
  • a connecting bolt with part of its length engages in each of these sliding sleeves. With the other part of its length, each connecting bolt is passed through an opening in the wall element and projects beyond the other side of the wall element.
  • connection formwork which is a lost formwork and which already contains all the elements necessary for the formation of the joint between two adjacent concrete slabs, makes it possible to concreting adjacent slabs in one operation and thus in a quick and efficient manner.
  • the connecting bolts and the associated sliding sleeves create a bond between the adjacent concrete slabs in such a way that these concrete slabs can move in the direction of the longitudinal extension of the connecting bolts (in the event of temperature fluctuations), so that the joint acts as an expansion joint, but the slabs move vertically cannot move to the connecting bolts.
  • the object of the invention is to further develop a connection formwork of the type mentioned at the outset that, with an optimal design of the joint between two concrete slabs and with the full effectiveness of this joint as an expansion joint, all elements of the connection formwork are reliably fixed to the wall element.
  • connection formwork is formed according to the characterizing part of claim 1.
  • connection formwork In the connection formwork according to the invention, an angle profile is provided on both sides of the wall element in the area of the upper longitudinal edge of this wall element, which extends in the direction of the upper longitudinal edge.
  • the angle profiles In the case of finished concrete slabs, the angle profiles form a strip embedded in the respective concrete slab, which protects the edge at the connecting joint between the concrete slabs. This results in an optimal design of the joint. Thanks to the connecting elements, the angle profiles are reliably fixed even when the connection formwork is not yet installed. Since the connecting elements break at the specified tensile and / or compressive force, the function of the joint as an expansion joint is nevertheless ensured.
  • the wall element of the connecting formwork according to the invention consists, for example, 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 on 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.
  • the yoke surface 5 of a profile 2 or 3 abuts against each surface side of the plate 6 extending over the entire length of the formwork 1, specifically with the side facing away from the legs 4.
  • the yoke surfaces 5 and the plate 6 form the wall element of the formwork 1.
  • each sliding sleeve 8 On the side facing away from the plate 6 of the yoke surface 5 of the profile 3, a plurality of sliding sleeves 8 made of plastic are fastened, in such a way that each sliding sleeve 8 lies with its longitudinal extension perpendicular to the plane of the yoke surface 5 and thus also perpendicular to the longitudinal direction of the formwork 1.
  • Each sliding sleeve 8 is made in one piece with a sleeve-like body 8 'which is open at one end and closed at the other end and with a square fastening flange 8' ', the latter protruding radially beyond the open end of the sleeve-like body 8'. With this fastening flange 8 ', each sliding sleeve 8 is fastened in the manner described later on the side of the yoke surface 5 of the profile 3 facing away from the plate 6.
  • a 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 at a distance determining the expansion range from the closed end, which is distant from the profile 3 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 around the axis of the opening 11 against each other by 180 ° offset areas 12, the material of the profile element 3 is pressed out or deformed such that the areas 12 protrude beyond the side of the yoke surface facing away from the plate 6, the areas 12 thus form tab-like projections, behind which two diagonally opposite corners of the fastening flange 8 ′′ can snap into place. Otherwise, the fastening flange 8 ′′ lies with its side facing away from the body 8 ′ against 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 legs 4, the structural steel fabric 15 projects beyond the side of the profile 3 facing away from the plate 6.
  • a structural steel 14 extending perpendicular to the longitudinal extent of the formwork 1 is bent at one end and forms a holder 14 'with this end.
  • the closed end of the body 8' of the sliding sleeve in question is then fixed in an adjustable manner, so that the sliding sleeve 8 held with its flange 8 '' on the profile 3 and with its other end adjustable on the holder 14 'and the one in it provided connecting bolts 10 can be aligned exactly perpendicular to the yoke surfaces 5.
  • a connecting pin 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 length of the structural steel 14 forming the holder 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 slab 6 adjusts the course of the expansion joint between the two adjacent ones Forms plates and the angled length 15 'of the structural steel fabric 15 is at the bottom of the support 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 can be fixed with the section 15 '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 holders 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.
  • the of the wall elements 20 and 21 are in the in The embodiment shown in FIG. 5 is only angled at its lower longitudinal edge there, ie each has an angled portion 22 corresponding to the leg 4.
  • each wall element 20 or 21 bears against the inner surface of a leg 23 'of an angle profile 23 made of steel.
  • Each angle profile 23 preferably produced by hot rolling, extends perpendicular to the plane of the drawing in FIG. 5 and lies flat with the outer surface of the leg 23 'against a surface side of the plate 6.
  • each angle section 23 points away from the plate 6.
  • the legs 23 'perpendicular to the planes of the plate 6 thus correspond to the upper legs 4 of the profiles 2 and 3 of the connection formwork 1.
  • the angle profiles 23 have on their legs 23' and 23 '' a compared to the thickness of the wall elements 20 and 21 much greater thickness.
  • the legs 23 ' lie with their upper side in alignment with the upper side of the respective concrete slab and thus form a strip which is concreted into the respective concrete slab and protects the edge at the connecting joint between the concrete slabs.
  • the two angle profiles 23 are provided with a plurality of screw bolts 24 Nut threads 25 connected to each other or to each other with plate 6 in between tense.
  • the bolts are made of steel, ie preferably made of stainless steel.
  • the nut threads 25 are each frustoconical or conical and made of plastic or another material, which guarantees a strength, in particular in the area of the thread of the nut thread piece 25, which ensures the fixing of the angle profiles 23 in the case of the not yet installed formwork 1a, when installed Formwork, that is to say in the case of finished, adjoining concrete slabs but in the event of temperature-related changes in the slab size in the area of the thread, so that despite the original connection or bracing of the angle profiles 23 by means of the screw bolts 24 and the nut threads 25, a change in the width of the slab 6 expansion joint formed is possible. It is also important in the embodiment shown that each nut thread piece 25 tapers to the adjacent leg 23 ', i.e.
  • each screw bolt 24 is not exposed in the area of the nut thread piece 25, ie via the nut thread piece 25 does not protrude and this nut thread piece also bears against the adjacent leg 23 ', so that the respective screw bolt 24 is embedded with its head only in one concrete slab, but not in the other of the two concrete slabs.
  • each bolt 26 is welded at one end to each angle profile 23, which extend obliquely downward from this leg 23''in such a way that each bolt 26 is level with the Top of the associated leg 23 '' encloses an angle of approximately 450, which opens towards the side facing away from the plate 6.
  • Each bolt 26 is provided with a head 27.
  • the bolts 26 reliably anchor each angle section 23 in the concrete of the respective slab. Furthermore, it is also possible to connect the reinforcing bars of the respective concrete slab by welding with the bolts 26 or their heads 27, as is shown for the reinforcing steel 28.
  • the formwork 1a in turn has the sliding sleeves 8, which are provided on the wall element 21, and the associated connecting bolts 10, each of which extend into a sliding sleeve 8 and are passed through the plate 6 and the wall element 20 and with their other end over that of the plate 6 protrude away from the wall element 20.
