Definitions

  • the invention relates to a formwork element as part of a lost Formwork for industrial floors made of concrete according to the preamble of claim 1, wherein the Formwork essentially from the edges of a Concrete field protective formwork element as well if necessary a shim, spacers, Sliding plates and sliding dowels exist, which Formwork element made of two edged profiles Metal sheet is made, which is vertical in the installed position directed legs almost without gap to each other are arranged and their horizontal legs are directed away from each other and the Form a footprint on the ground, whereby the free ends of the vertically directed legs folded at right angles away from each other are so that each profile section is approximately U-shaped is trained.
  • Such formwork elements are in the prior art Technology known for example from EP-A-410079.
  • Such industrial floors are used, for example, in Driving range of forklift vehicles, others Vehicles, especially in the area of shelf and High-bay systems or in cold stores and freezers used. It is essential that the individual Approximately concrete fields of the industrial floor be connected to each other without gaps, whereby the formwork elements protect the edges the concrete fields should be reached.
  • Industrial flooring in such a way that on one A film is applied to the surface then formwork elements are applied.
  • To the Formwork elements are arranged with sliding dowels the vertical legs of the formwork elements enforce sleeve-like formations. The Legs of each edged profile are through in Stiffeners spaced apart.
  • This training is largely a Edge protection of the edges of the concrete field formed so that damage to the edge of the Concretes only occur to a small extent.
  • the Formwork elements with the corresponding Concrete material of the concrete field are connected, can cause shrinking movements of the Concrete field follow without demolition between the concrete and the corresponding L-shaped Profile is coming.
  • the corresponding U-shaped profiles can be made from suitable metal sheet can be folded, being as Starting material with sheet steel, for example Corrosion protection or stainless steel is used can come.
  • the formation of profiles in the form of folded metal sheets is essential for that Training of the formwork element, as it is theoretically possible is rolled profiles use, but they are too heavy to manual laying of the formwork elements enable. It would also be the case with rolled profiles required, depending on the web height of the profile to hold different rolling tools.
  • the profiles from folded sheet metal can be made relatively lightweight are, so that the individual profile sections of one or two people are easy to handle, with a change in height of the web height same material cutting is possible. there only the leg length changes while the bridge height is then variable. So it's one inexpensive manufacturing and a assembly-friendly handling possible.
  • the edge of the joint cover profile can be in the finished concrete field either be embedded flush in the concrete mass, or, what is preferred, this Joint cover profiles are available with their sheet thickness over the surface of the concrete field, whereby then through the monolithic hard material coating the top of the concrete field flush connection to the joint cover profiles is achieved.
  • the wall thickness some of the profiles and / or joint cover profiles Is millimeters, preferably about 2 mm to 6 mm, in particular about 4 mm.
  • the wall thickness of the profiles should be such that that the profiles are sufficiently resilient is guaranteed, but also on the other hand it is ensured that the profiles with controllable forces can be folded. This has a profile thickness of approx. 4 mm emphasized particularly suitable.
  • the connecting means can for example Be plastic fasteners for proper connection of the profiles and are determined, but after concreting the Formwork elements the shrinkage-related Do not hinder relative movement, but at Such forces break or crack.
  • the formwork element 1 is part of a lost formwork for industrial floors Concrete.
  • the formwork consists essentially of the the edges of the respective concrete field protective formwork element 1 as well as in the Drawing further elements not shown, namely a washer, spacers, Sliding sheets, sliding dowels and reinforcing steel mats.
  • the formwork element 1 consists of two edged Profiles made of sheet steel, in the installed position vertically directed legs 2 approximately to each other are arranged without gaps and their lower horizontal legs 3 directed away from each other and the footprint on the ground form. For this purpose, these legs 3 are relatively long trained to keep the Formwork element 1 on the ground guarantee.
  • the free ends 4 of the vertically directed Leg 2 at the upper end of the formwork element are directed away from each other at right angles folded so that they are parallel to the legs 3 run.
  • Each section of the formwork element 1 is thus approximately U-shaped, the Length of the legs 3, 4 is not the same, but is different.
  • the joint cover profile consists of two flat bars 5, 6, one (5) of which on the profile end 4 of the first profile is fixed and over the joint gap 7 to over part of the profile end 4 of the second Profiles engages while their other (6) on the Profile end 4 of the second profile is fixed. Both Flat bars 5, 6 close in the target position narrow gap 8 between their abutting edges on.
  • the components of the joint cover profile 5, 6 are in the support area on the respective Profile end 4 with holes 9 and in Punching area by punching welding firmly connected to the profile end 4, the The weld is then flexed or is smoothed so that a flat Visible surface is formed. Furthermore, the Components 5, 6 of the joint cover profile on the respective profile ends 4 by means of welding points to be pinned to a pre-fixation before ensure final fixation.
  • the wall thickness of the profiles (2, 3, 4) and the Joint covering profiles 5, 6 is preferably about 4 mm.
  • the vertical legs 2 of the profiles are connected to one another by connecting means 10, after casting the lost formwork Concrete material with shrinkage Relative movement of the concrete formwork elements 1 break or tear so that the hold of the Formwork elements on the corresponding concrete mass is ensured and only the joint 7 between the profiles of the formwork element 1 itself slightly enlarged. This also increases the joint 8, wherein the joint gap above the one End 4 of a profile of the formwork element 1 lies.
  • the training according to the invention enables excellent protection of the edges of the respective concrete fields, the parting line 8 is relatively narrow, so that when No running over with vehicles or the like Chatter marks or the like are formed.
