Definitions

  • the present invention relates to a formwork element and a formwork system for concrete construction.
  • Concrete structures such as floor / ceiling slabs are often concreted in several sections. Reasons for this are, for example, mixing new concrete or taking a break between pouring the individual sections. This creates construction joints that have to be sealed against moisture.
  • the shuttering elements used for this purpose are usually made of steel and have larger dimensions, which leads to a high weight and corresponding difficulties when used on the construction site.
  • the DE 20 2009 005 173 U1 also describes a permanent formwork for concrete construction with two formwork parts and a sheet metal strip designed as a flat water barrier.
  • the two formwork parts are aligned with one another lying in one plane, the sheet metal strip being arranged between the two formwork parts and perpendicular to the plane of the formwork parts.
  • the sheet metal strip protrudes on both sides over the level of the formwork parts.
  • the sheet metal strip has fastening elements on both of its surfaces for fastening the formwork parts, the formwork parts being connected to the sheet metal material strip in a force-locking manner in the fastening elements.
  • the floor / ceiling slabs to be concreted do not extend in their entire extent in one plane, but rather offset in the vertical direction.
  • the floor / ceiling plate thus has two flat sections which, as a rule, run parallel to one another, but are arranged offset from one another in the vertical direction.
  • the shuttering of the area in which the height offset of the floor / ceiling slab takes place and the sealing of this area against water is currently carried out with a great deal of work with the help of improvised formwork parts attached to one another at the construction site.
  • the invention as it is characterized in the claims, is based on the object of providing a formwork system by means of which vertically rebounding floor / ceiling panels can be paneled in a simple manner in the area of the projection and equipped with a water seal.
  • the formwork element according to the invention for concrete construction comprises a lower formwork part, an upper formwork part, a slotted formwork part, a horizontal sheet metal strip designed as a flat water barrier and a vertical sheet metal strip designed as a flat water barrier.
  • the lower formwork part, the upper formwork part and the slotted formwork part are arranged in a common plane, wherein the horizontal sheet metal strip is arranged between the formwork parts that it is aligned essentially perpendicular to the plane of the formwork parts and a first surface of the horizontal sheet metal material strip upper formwork part and the slotted formwork part faces and a second surface of the horizontal sheet metal strip faces the lower formwork part and the horizontal sheet metal material strip protrudes on both sides over the plane of the formwork parts.
  • the upper formwork part and the slotted formwork part are firmly connected to the first surface of the horizontal sheet metal strip and the lower formwork part is firmly connected to the second surface of the horizontal sheet metal strip.
  • the vertical sheet metal strip is arranged between the upper formwork part and the slotted formwork part that it is aligned essentially perpendicular to the plane of the formwork parts and a first surface of the vertical sheet metal material strip faces the upper formwork part and a second surface of the vertical sheet metal material strip faces the slotted formwork part is facing and the vertical sheet metal strip protrudes on both sides over the level of the formwork parts.
  • the upper formwork part is firmly connected to the first surface of the vertical sheet metal material strip and the slotted formwork part is firmly connected to the second surface of the vertical sheet metal material strip in the vertical direction via a portion of its extent extending from the first surface of the horizontal sheet metal material strip, the horizontal Sheet metal material strips and the vertical sheet metal material strips are arranged perpendicular to one another and are firmly connected to one another.
  • a slot-like recess is provided between the second surface of the vertical sheet metal strip and the slotted formwork part, the slot-like recess extending from the edge of the slotted formwork part facing away from the first surface of the horizontal sheet metal material strip over at least 3% of the vertical extent of the slotted formwork part.
  • Such a formwork system for concrete construction comprises at least one first formwork element according to the present invention and at least one second formwork element according to the present invention, the first formwork element and the second formwork element being arranged in relation to one another so that the vertical sheet metal strip of the first formwork element enters the slot-like recess of the engages the second formwork element and the vertical sheet metal strip of the second formwork element engages in the slot-like recess of the first formwork element.
  • the second surface of the vertical sheet metal strip of the first formwork element is then in contact with the second surface of the vertical sheet metal material strip of the second formwork element.
  • Such a formwork system constructed from two formwork elements according to the invention creates the possibility of encasing a vertically rebounding floor / ceiling panel in the region of the projection in a very simple way to provide a seal against water.
  • the cladding is done by two prefabricated standard elements delivered to the construction site, which only have to be plugged into each other in the manner described in order to get to a formwork that clad a vertically protruding floor / ceiling plate and equips it with a water barrier.
  • the formwork system can be adapted to any conceivable installation situation thanks to the different dimensions of the vertical sheet metal strips and the various formwork parts. Both the horizontal extension of the floor / ceiling plate and the height of the vertical offset can be simulated in a simple manner.
  • the prefabricated formwork elements only need to be manufactured according to the previously known dimensions of the floor / ceiling slab.
  • the shuttering parts of a shuttering element arranged on the two sides of a water barrier are usually arranged in a common plane.
  • An offset of the shuttering parts arranged on different sides of, for example, a seam sheet relative to one another does not bring any technical advantages, but the water barrier would have to be dimensioned wider accordingly so that it protrudes over the shuttering parts on both sides by the required amount. If, in the context of the present text, it is pointed out in the general description and in the exemplary embodiments that the lower formwork part, the upper formwork part and the slotted formwork part are arranged in a common plane, then the technical requirements mentioned are owed. An insignificant offset of the formwork parts of a formwork element relative to one another is of course covered by the present invention.
  • the height T of the slotted formwork part can vary over a wide range. Starting with an extension of a few 10 cm for concreting smaller steps up to an extension of 3 m or even 5 m for concreting entire building floors.
  • the slot-like recess which, as will be explained in more detail below, defines the overlapping area of two strips of sheet metal material designed as a water barrier, should extend over at least 100 mm in the vertical direction. In the case of formwork parts with a height T of several meters, it is therefore completely sufficient if the slot-like recess, as defined according to the invention, extends over at least 3% of the vertical extent of the slotted formwork part.
  • the formwork parts are preferably welded to the sheet metal strip. Since the formwork elements and the formwork system formed from these formwork elements must have sufficient stability, on the one hand, to be able to be installed on the construction site without any problems and, on the other hand, to be able to withstand the concrete pressure after pouring the in-situ concrete into the formwork, formwork parts and sheet metal strips must be firmly and permanently connected to one another. Welding the individual parts is particularly suitable for ensuring a stable connection.
  • the formwork parts comprise a lattice mat comprising transverse and longitudinal bars and a perforated metal sheet welded in between the transverse and longitudinal bars of the lattice mat.
  • the perforated metal sheet is particularly preferably an expanded metal sheet or a perforated sheet.
  • the cross bars of the metal grid are preferably welded to the longitudinal bars of the metal grid at their crossing points.
  • the transverse and longitudinal bars of the metal grid are also welded to the perforated metal sheet.
  • the openings are advantageously chosen large enough on the one hand to ensure a durable and stable connection of the concrete of the two adjacent concreting sections through the concrete slurry passing through, but on the other hand not so large that the concrete of the first concreting section can flow through the openings.
  • the thickness of the transverse and longitudinal bars of the metal grid and the distance between the transverse and longitudinal bars can be optimized.
  • At least one strip of sheet metal material is provided with a sealing coating on its first and / or second surface at least partially, preferably over the entire area.
  • the at least partial, preferably all-over, coating achieves a particularly good seal against water.
  • Another advantage is associated in particular with the coating of the vertical strips of sheet metal.
  • a formwork system according to the present invention has at least a first and at least a second of the formwork elements described above.
  • the first formwork element and the second formwork element are arranged in such a way that the vertical sheet metal strip of the first formwork element engages the slot-like recess of the second formwork element and the vertical sheet metal material strip of the second formwork element engages the slot-like recess of the first formwork element.
  • the second surface is then in this arrangement of the vertical sheet metal strip of the first formwork element in contact with the second surface of the vertical sheet metal material strip of the second formwork element. If the two vertical strips of sheet metal are now at least partially, preferably all over, equipped with a sealing coating which always has a certain stickiness, the two vertical strips of sheet metal are firmly connected to one another after their surfaces have been brought into contact, namely firmly glued to one another. This gives the entire formwork system additional stability when it is being set up. In addition, when vertical strips of sheet metal are glued together, the formwork system provides additional security against circulating water.
  • the sealing coating can in principle be applied to the sheet metal strip in any manner known to the person skilled in the art.
  • the sealing coating preferably has an adhesive layer for attachment to the sheet metal strip. Before it is applied to the sheet metal strip, the adhesive layer of the coating is usually covered with a paper strip. For attachment, the paper strip can then simply be peeled off the coating and the adhesive layer can be pressed onto the sheet metal strip. A durable connection between the coating and the sheet metal strip is created in a simple manner.
  • the coatings described in more detail below are usually materials that can be melted at higher temperatures without decomposition. Spraying the liquid coating material onto the sheet metal strip can therefore be used as a further preferred type of application of the coating to the sheet metal strip.
  • the coating material is sprayed onto the sheet metal strip with the aid of a spray nozzle, where it cools down and results in a solid sealing coating.
  • the coating is provided with a protective coating until it is used as part of a water barrier.
  • the materials used as the sealing coating give the coating in any case a sticky surface that bonds well with the poured concrete in a known manner. To protect these sticky surfaces, a layer of paper or a plastic film is usually used, which is then peeled off the coating before the concrete is poured.
  • the sealing coating ensures that the joint is sealed against water.
  • the surfaces of the coatings fit well with the Connect concrete on both sides of the joint.
  • the coating therefore has a sticky surface that bonds permanently to the adjacent concrete. If the expected shrinkage of the concrete occurs during hardening, the sealing coating on both sides of the formwork is pulled along by the concrete, with the thickness of the coating increasing. In this way, the sealing coating ensures that the joint is reliably sealed against water.
  • any type of coating which has the properties mentioned can be used as a sealing coating in the context of the present invention.
  • Coatings that essentially consist of butyl rubber, bentonite, bitumen rubber, a hot melt adhesive or a swellable plastic are particularly suitable.
  • "Swellable plastic” is understood to mean all conventional thermoplastic elastomers equipped with a swellable material. Swellable plastics can be obtained on the market in film form or in the form of tapes.
  • Butyl rubber is polyisobutylene that has been modified with resins and fillers (e.g. calcium carbonate).
  • Bitumen rubber is a product made from petroleum, the exact composition of which varies. Bentonite is a swellable mixture of different clay minerals. The main component is montmorillonite (60 - 80%), accompanying minerals are quartz, mica, feldspar, pyrite or calcite.
  • the thickness of the coating is chosen so that, on the one hand, the coating adheres to the hardening concrete even if the concrete shrinks, but on the other hand, no superfluous coating material is applied to the lost formwork.
  • the sealing coating preferably has a thickness between 0.1 mm and 5 mm, particularly preferably between 0.15 mm and 3 mm, in particular a thickness between 0.2 mm and 2 mm and particularly preferably a thickness between 0.5 mm and 1, 5 mm. A thickness of the sealing coating of around 1 mm has proven to be particularly advantageous.
  • the coating materials mentioned in the coating thicknesses mentioned can increase their volume by at least 50% and up to 100% under tensile loading. This ensures a good seal of the joint even if the concrete shrinks.
  • the slot-like recess extends from that of the first surface of the horizontal Sheet metal strip facing away from the edge of the slotted formwork part over at least 10% of the vertical extent of the slotted formwork part, particularly preferably over at least 25%, especially preferably over at least 50%, very particularly preferably over at least 70% and in particular over at least 90% of the vertical extent of the slotted formwork part .
  • the slot-like recess extends, starting from the edge of the slotted formwork part facing away from the first surface of the horizontal sheet metal strip, over a maximum of 95% of the vertical extent of the slotted formwork part, particularly preferably over a maximum of 80%, particularly preferably over a maximum of 50%, very particularly preferably over a maximum of 30% of the vertical extension of the slotted formwork part.
  • the present invention also includes all sensible combinations of the mentioned minimum and maximum values of the extent of the slot-like recess.
  • the slot-like recess extends starting from the edge of the slotted formwork part facing away from the first surface of the horizontal sheet metal strip, for example over at least 10% and a maximum of 95% of the vertical extent of the slotted formwork part or over at least 25% and a maximum of 80% of the vertical Expansion of the slotted formwork part or over at least 70% and a maximum of 95% of the vertical extent of the slotted formwork part.
  • all combinations of the mentioned minimum and maximum values of the extent of the slot-like recess that are sensible for the person skilled in the art are covered by the present invention.
  • the slot-like recess By dimensioning the slot-like recess, it must be ensured on the one hand that the vertical sheet metal strip of the first formwork element can engage sufficiently far into the slot-like recess of the second formwork element and that the vertical sheet metal material strip of the second formwork element can engage sufficiently far into the slot-like recess of the first formwork element. A sufficient overlap of the two vertical sheet metal material strips ensured in this way is necessary in order to ensure reliable sealing of the vertical section of the floor / ceiling plate in the area of its offset. On the other hand, the slot-like recess should not extend completely to the horizontal strip of sheet metal material, since then it would not be possible to fasten the vertical strip of sheet metal material to the slotted formwork part.
  • a slot-like recess is preferably provided between the first surface of the horizontal sheet metal strip and the slotted formwork part, the slot-like recess extending from the edge of the slotted formwork part facing away from the second surface of the vertical sheet metal material strip over a maximum of 50% of the horizontal extent of the slotted formwork part.
  • a slot-like recess is also preferably provided between the first surface of the horizontal sheet metal strip and the upper formwork part, the slot-like recess extending from the edge of the upper formwork part facing away from the first surface of the vertical sheet metal material strip over a maximum of 50% of the horizontal extent of the upper formwork part.
