Definitions

  • the invention relates to a modular formwork system for forming a formwork for the production of ring anchors, ring beams or lintels made of concrete, having at least a first formlining holding element and a formlining, in which at least one first formlining holding element has at least one formlining receptacle, so that a formlining can be set at a defined location.
  • a well-known formwork is in the DE 202 12 134 U1 described, which comprises the formwork by means of two edge plates, which are connected to one another by screwed-on U-brackets made of sheet steel and which can be placed or attached to the masonry, whereby additional stabilizing brackets can be provided, which are used when pouring the concrete into the formwork space formed by the edge plates prevent the edge panels from spreading.
  • Prefabricated formwork is typically assembled by the manufacturer.
  • For formwork for ring anchors, the required stability is achieved through factory assembly.
  • the US 3,778,020 A describes a formwork clip as a base element made of plastic that is used to hold vertical wall elements.
  • the plastic element is attached to a ground foundation.
  • the formwork holder is arranged above a concrete foundation. In principle, it is possible to arrange several formwork elements one above the other in a vertical direction.
  • the DE 200 16 264 U1 describes a mounting element for fastening permanent formwork to masonry. It is a prefabricated system that can be used on a construction site when fully assembled.
  • the formwork system should be easy and inexpensive to transport and cause low storage costs.
  • a modular formwork system for concrete parts in particular ring anchors or ring beams including lintel covers, is intended as the upper end of a masonry structure; which comprises formwork modules in the form of at least one first holding element, which supports both the economical production of the formwork skin on the construction site and the holding of the reinforcements.
  • the formwork system consists of a first formwork module, usually the lower holding element and a further holding element in the form of an upper holding element.
  • a shear reinforcement retaining element can also be used.
  • the holding elements are preferably made of plastic. Due to the comparatively low mechanical requirements for the holding elements, practically all materials can be used that support the shaping of the holding elements. For example, resin-bound green compacts, plastic recycling material of any density or plastics with embedded residues of wood or paper materials (in practical terms stretched plastic), other composite materials or metal or stainless steel can be used. Also conceivable are holding elements that are made based on pressed (waste) paper with the addition of a binder, whereby there must be at least temporary resistance to liquid.
  • the basic idea according to the invention is the realization of a formwork system through a modular structure of the holding elements, which implement both holding tasks for the actual formlining as well as for the reinforcement.
  • the reinforcement is also modular, meaning that the reinforcement elements for the longitudinal and shear reinforcement are not formed in one piece by a reinforcement cage, but are inserted into the holding elements as separate elements on the construction site.
  • the formlining can be made from EPS, PUR or other insulation panels, fiber cement panels or composite panels, for example from fiber cement and insulation materials. Wood materials or plastics are also suitable. Concrete primers can be provided on the outside and/or inside to ensure a better bond (inside) to the concrete or (outside to) plaster.
  • the inventive design of the formwork system opens up a variety of technical and economic advantages. Cost advantages arise from the simplified production option as mass-produced goods with a simple structure (which do not have to be assembled into partially finished products in the factory). Transport and storage costs are reduced compared to existing formwork systems and the on-site assembly or installation of the reinforcement on the construction site takes less time and is therefore less labor intensive.
  • the included fixings for the reinforcing elements designed as individual elements to be installed eliminate the time-consuming and costly weaving of reinforcement cages and the installation of spacers to maintain the necessary concrete cover, which is required in the prior art. Due to the modular design, it is only necessary to produce, transport and provide the upper and lower mounting elements as well as the optional floor parts as a lower formwork skin to bridge openings, such as a lintel, for the different wall thicknesses. It is also conceivable to produce the upper and lower holding elements in two parts in such a way that they can then be plugged together and have locking provisions for the different (masonry) widths. It would then no longer even be necessary to produce, transport and maintain the upper and lower holding elements for each individual (masonry) width.
  • the side formlining and the holding elements for fixing the shear reinforcements are independent of the wall thickness of the concrete part to be produced and therefore do not have to be manufactured, transported and maintained separately for each wall thickness.
  • the complex and cost-intensive factory manufacturing of the various factory-assembled U-formworks for the different wall thicknesses, as well as their cost-intensive transport, maintenance and storage, are no longer necessary.
  • the lower retaining elements are first placed on the top of the wall.
  • the lower mounting elements are designed in a U-shape for mounting on the edge of the wall, so that there is a clamp-like situation that corresponds to the width of the wall.
  • the legs of the U-shaped component of the lower holding element rest against each other on the side wall walls and in this way fix the lower holding element.
  • Holes can be provided on the underside in the lower mounting elements in order to enable additional or alternative fastening independent of the fixing by the legs, for example using steel nails, screws or impact dowels, if, for example, there are high mechanical requirements for the connection of the lower mounting element to the masonry .
  • the distance from a first lower holding element to further lower holding elements is i. depending on the geometric conditions of the concrete part and the size of the formwork panels to be used. d. R. about 50 cm or more.
  • the lower mounting elements can support receptacles or holes for a template for the exact positioning of the lower mounting elements with one another.
  • the lower holding elements have receptacles for fixing the elements of the longitudinal reinforcement, which are usually formed by BSt500S reinforcing bars according to DIN 488, which ensure the required concrete cover.
  • the side formwork is inserted, which forms the formlining.
  • the side formwork is supported by the formwork panels z. B. made of fiber cement and are usually 25 cm high or higher.
  • the shear reinforcement retaining elements are then attached to the formwork panels (side formwork) on the inside of the formlining by attaching them to the side formlining on both sides.
  • Formlining receptacles are formed by a likewise clamp-like and U-shaped area of the shear reinforcement retaining elements, so that fastening is possible by pushing the formlining receptacle onto the formlining.
  • the shear reinforcement holding elements are used to fix and position the shear reinforcement, which are designed as U-shaped elements consisting of a BSt500S reinforcing bar, primarily with a thickness of 8 mm, and are installed in the formwork system in different, preferably two, orientations.
  • the U-shaped reinforcing elements are inserted with the cross legs downwards into the receptacles provided on the shear reinforcement holding elements, so that the closed sides of the U-shaped elements lie in the direction of the lower holding elements.
  • the longitudinal reinforcement is inserted into the receptacles of the lower retaining elements.
  • the subsequent assembly step is the installation of the upper mounting elements.
  • the upper mounting elements have receptacles for the upper longitudinal reinforcement, which is also installed. If shear reinforcement is required, a second shear reinforcement element is then also inserted adjacent to the first shear reinforcement element in designated receptacles of the shear reinforcement holding elements, with the open side of the U-shaped bracket of the second shear reinforcement element pointing downwards.
  • the concrete can be poured into the switched-on room. After the concrete has hardened, external parts of the formwork system can be removed using predetermined breaking points.
  • the formwork skin can be used again after dismantling or it can remain on the concrete part as so-called lost formwork. If the formwork skin has been created with its inner edge flush with the outer edge of the masonry, the formwork skin can be removed after concreting and reused. If the formwork skin has been implemented with its outer edge flush with the outer edge of the masonry, it remains on the concrete part as “lost formwork”.
  • All holding elements of the formwork system according to the invention are designed with regard to the relative positioning means of the reinforcements in such a way that the required concrete cover is reliably achieved in all assembly situations and geometric conditions of the concrete part to be produced.
  • Figure 1 shows a front view of the lower holding element (10).
  • the lower holding elements (10) which are preferably installed several times in the formwork system, fix the side formlining, which essentially consists of formwork panels (right and left of the axial direction of the concrete component), either as a conventional formlining (inner edge of the formwork skin flush with the outer edge of the masonry, not shown), which is according to is removed after concreting, or as lost formwork (outer edge of formwork skin flush with the outer edge of masonry, Fig. 1 shows this situation), which remains in the concrete part.

  • the lower holding elements (10) have receptacles (11, 11') on both sides for two reinforcement elements.
  • the overlap length is understood to mean the overlap dimension of the round or profile bars that form the longitudinal reinforcement elements. If these elements were only placed together at the front, no tensile force transmission would be possible at these points, so an overlap is created to prevent this.
  • the lower holding elements (10) are attached from above to the masonry on which the concrete part is to be concreted, for example as a ring anchor or ring beam.
  • the lower tabs (12) can be equipped with a threading bevel (13) in the lower area.

  • the lower mounting elements (10) can have fastening points on the underside (15), such as holes, through which they can be fixed to the masonry with steel nails or hammer dowels or similar if necessary in addition to or as an alternative to the fixing as a result of the tabs (12). .
  • the underside (15) of the lower holding elements (10) can have a rough surface in order to enable the lower holding elements (10) to be glued to the masonry using, for example, tile or PU adhesive or other adhesives.
