Definitions

  • the invention relates to a reinforcement cage comprising an upper reinforcement profile and a lower reinforcement profile, optionally at least one insulating body in which the upper reinforcement profile and the lower reinforcement profile are embedded, as well as tension and compression reinforcement elements, which are arranged on the upper reinforcement profile and / or lower reinforcement profile.
  • reinforcing elements can lead to a cold bridge being formed between an exterior area such as a concrete slab and an interior area such as a floor slab by the steel reinforcements normally used, which of course is undesirable.
  • reinforcement baskets were developed. Different variants of reinforcing baskets are in particular the EP 1 151 167 A1 can be seen, in which also further prior art is shown.
  • a reinforcement cage of the type mentioned wherein an upper reinforcement profile and a lower reinforcement profile are each U-shaped. These two reinforcement profiles are connected to each other via a vertical connecting plate. While the reinforcing profiles mainly absorb tensile and compressive forces, the connecting plate according to EP 1 151 167 A1 in particular to absorb shear forces.
  • the object of the invention is to provide a reinforcing cage of the type mentioned, in which can be dispensed with a connecting plate between the reinforcement profiles, without this being at the expense of higher heat conduction through the reinforcing cage.
  • the reinforcing cage of the type mentioned above the upper reinforcement profile and / or the lower reinforcement profile at least substantially closed and / or formed with a central web.
  • an appropriate measure such as the formation of at least the upper or lower reinforcing profile with a closed cross-section also shear forces can be better absorbed than before, so that even with the elimination of a connecting plate between the reinforcement profiles, the reinforcement profiles can be structurally relatively thin, so no increased heat conduction occurs.
  • the same mass can be better distributed to improve the thrust load without a disadvantage would be associated with a higher heat conduction. Closed cross-sectional profiles or at least substantially closed cross-sectional profiles are preferred.
  • a central web in at least one of the reinforcing profiles, which preferably extends vertically along a vertical axis of the reinforcing cage.
  • the upper reinforcing profile and / or the lower reinforcing profile are preferably formed closed. It is particularly preferred that both reinforcing profiles are the same, that is each formed closed.
  • the reinforcement profiles are formed, for example, with the cross-sectional profile of an I-beam.
  • the upper reinforcement profile and the Lower reinforcement profile results in the advantage of a small-scale production, since the reinforcement profile for the top and the bottom is cut off only from a semi-finished product. It then follows that the upper reinforcement profile and the lower reinforcement profile are formed with the same cross-section normal to a longitudinal axis of the reinforcing cage.
  • the reinforcing profiles are designed in part with a cross section which is partially open at most up to 25%, preferably up to 20%, in particular up to 15% open, the at least one opening of the upper reinforcement profile of the at least one opening of the lower Reinforcement facing, although other positions are possible.
  • the upper reinforcement profile and / or lower reinforcement profile are rectangular or square in cross-section.
  • the two reinforcing profiles are again formed the same. Due to the closed training in a rectangular shape or optionally in square shape shear forces can be particularly well absorbed.
  • the required additional tension and compression reinforcement elements are particularly easy to attach to the reinforcement profiles.
  • An attachment of the tension and compression reinforcement elements can be made cohesively, for example by welding or gluing.
  • non-positive and / or positive connections such as screw, which allows greater flexibility for attaching the tensile and compressive reinforcement elements with variable size and / or shape, depending on the load profile.
  • suitable receptacles with internal thread or the like are provided on the reinforcement profiles.
  • other hollow profiles can be used.
  • the reinforcement profiles are usually made of a non-rusting material, such as a stainless steel.
  • the reinforcement profiles may also consist of a non-metallic or only partially metallic material.
  • Alternative materials are, for example, glass fiber reinforced plastic, composite materials of organic fabrics and metals or reinforced plastics of any type. Corresponding materials are suitable due to a low Thermal conductivity in principle particularly good and provide with suitable material setting or combination and the required properties for a sufficient power or transmission safe.
  • a connection of the tension and compression elements with the reinforcement profiles depends on the materials. Are reinforcing profiles formed of a stainless steel and are also the tensile and compressive reinforcement elements of a preferably stainless steel before, in particular, a welding in question. If other material combinations are given, it is usually necessary to switch to other types of connection than a material connection. In particular, plug and screw connections come into question, especially when components made of a glass fiber reinforced plastic to be connected to components made of a stainless steel. A coupling is usually done via suitable recordings that can be arranged on the reinforcement profiles.
  • a reinforcing cage according to the invention can have a large number of upper reinforcing profiles and lower reinforcing profiles. However, it is particularly preferred if a reinforcement cage has only a single upper reinforcement profile and a single lower reinforcement profile. This results in a einrippige training of the reinforcement cage.
  • Upper reinforcement profile and lower reinforcement profile are preferably arranged one above the other along a vertical axis of the reinforcing cage.
  • the einrippige training of the reinforcing cage is advantageous in that in each case a reinforcement cage with a rib can be positioned at a location exactly where force is to be absorbed or transferred.
  • an arrangement with a plurality of reinforcing cages consist, each reinforcement cage with a single upper reinforcement profile and an opposite lower reinforcement profile is formed and the reinforcing baskets are at least partially spaced from each other.
  • FIG. 1 an inventive reinforcement cage 1 is shown in cross section.
  • Fig. 2 shows a side view of the reinforcing cage 1.
  • the reinforcing cage 1 has an upper reinforcement profile 2 and a lower reinforcing profile 3.
  • the upper reinforcement profile 2 is arranged above the lower reinforcement profile 3.
  • tensile and pressure reinforcing elements 5, 6, 7, 8 are arranged on both sides of a vertical axis V on the upper reinforcing profile 2 and on the lower reinforcing profile 3.
  • an insulating body 4 is provided, which surrounds upper reinforcement profile 2 and lower reinforcement profile 3 in regions in the center.
  • the insulating body 4 is located at the later installation at a transition between an outdoor area and an interior of a building.
  • the upper reinforcement profile 2 runs like the lower reinforcement profile 3 through the insulating body 4 therethrough.
  • Both the upper reinforcing profile 2 and the lower reinforcing profile 3 and the tension and compression reinforcement elements 5, 6, 7, 8 protrude on one side into an inner area and on the other side into an outer area of the components to be concreted.
  • the tensile and compressive reinforcement elements 5, 6, 7, 8, which are shown only in the connection area to the reinforcement profiles 2, 3, can extend substantially horizontally, but can also be bent by bending at a suitable location for example 90 °, for example when a Wall element is to be connected to a ceiling element.
  • both the upper reinforcement profile 2 and the lower reinforcement profile 3 in cross-section to a longitudinal axis L of the Reinforcing basket 1 formed with a rectangular profile, which is closed.
  • a connecting plate for connecting the upper reinforcement profile 2 with the lower reinforcement profile 3 can therefore be omitted.
  • This allows in particular a simplified attachment of the insulating body 4, which usually consists of a variety of items. Now, if there is a free space, the items can be positioned much faster. In addition, less work is required in the production of the reinforcement cage 1, because a composite sheet does not have to be separately connected to the reinforcement profiles 2, 3, for example by welding.
  • FIG. 3a to 3i Further possible cross-sectional profiles for the reinforcement profiles 2, 3 are shown.
  • the alternative cross-sectional profiles are all closed or essentially closed or provided with a preferably vertical web 9.
  • a special case of a closed profile is in Fig. 3i represented, namely a rod made of solid material, which has no openings.
  • the concept here is in all cases, on the one hand, to distribute the available mass so that there is a favorable power distribution, but on the other hand there is no disadvantageous higher heat conduction between an outer area and an inner area due to the distribution of the same mass. The distribution of mass is thus optimized with respect to both aspects.
  • both the upper reinforcement profile 2 and the lower reinforcement profile 3 are made of a non-rusting material.
  • a non-rusting material for this purpose, in particular a stainless steel in question.
  • other materials which bring the required high load capacity in all stress areas (tension, pressure and thrust).
  • fiber-reinforced plastics or the like come into question. If components made of different materials are connected to each other, in addition to a cohesive connection other types of connections are possible. In particular, a combination of a non-positive and a positive connection can be selected. Possible variants are plug-in or screw connections.
