    The invention relates to a device for connecting reinforced concrete slabs to a wall or ceiling construction of reinforced concrete, with an insulating body for thermal insulation and a reinforcement member having tensile and pressure reinforcing elements.
    In addition to the largest possible thermal insulation effect such devices must generally take high bending and transverse force stresses. The field of application is very diverse and includes applications with cantilevered as well as supported balcony and terrace slabs, continuous panels leaving the building envelope, support areas for loggias, thermal separation of attics and parapets up to consoles and wall panels.
    There are facilities for cantilevered reinforced concrete slabs are known, the overhead tensile reinforcement is formed depending on the Tragfähigkeitsstufe. In the transitional area of the thermal insulation level, a rebar of stainless steel is used. This is e.g. connected by resistance pressure welding with a subsequent rebar. Shear bars are made in the same stainless steel quality as the tie rods, with the connection to the • · · * * • · · · ·
    Connection reinforcement is again done by welding. As a thermal insulation material in the transition region, for example, polystyrene foam can be used. In these modules are integrated, for example, micro-steel fiber-reinforced high-performance fine concrete in the pressure zone.
    The well-known products, also known as "insulating baskets" have in common that the bending capacity decreases with increasing thermal resistance. The absorption of the lateral force is realized differently in the products. For some products, the lateral force is absorbed by stirrups. Insulating baskets of the applicant have a frame construction which transmits both moments and shear forces. Another solution consists in the arrangement of thrust plates, which are also decoupled from the torque transmission used to absorb the lateral force. The transverse force transmission by means of brackets or shear plates has a positive effect on the deformation behavior, since negligible shear distortions occur as a result of the higher shear stiffness in the transition region. In frame-like support systems, however, an additional deformation from the transverse force component is always to be considered. Systems that decouple moments and shear forces are generally preferred in terms of adaptation to the stresses. • »* #» φ · * · ι ft * * * *
    However, a disadvantage of the known devices is generally the lack of decoupling the torque and shear force capacity and the complex production.
    The invention aims to significantly improve the thermal insulation in the transition region of the insulating baskets and to increase the flexibility of the connection device so that similar to a modular system a variety of geometric constraints can be realized with one and the same product with simple assembly steps using high performance materials. The product should be optimized to such an extent that the economy of the product can be increased by simple grading options to adapt to the respective load capacity requirements.
    A connection device according to the invention of the type specified in the introduction is characterized in that the reinforcement part closed loops of fiber plastic tensile reinforcement elements and bending pressure thrust elements with variable profiles made of ultra high strength concrete (UHPFRC), wherein the horizontally arranged loops in the insulating body between the to be connected reinforced concrete slab and the wall or ceiling construction stored and the bending pressure thrust elements are integrated into the insulating body.
    According to a preferred embodiment of the invention, the closed loops of the tensile reinforcement consist of • t •
    made of carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GRP).
    According to a further feature of the invention, the bending pressure thrust elements consist of UHPFRC quality concrete.
    The invention and further features thereof are described below with reference to exemplary embodiments with reference to the drawings.
    Fig. 1 is a schematic side view of a device according to the invention; Fig. 2 is a principle front view of the device; Fig. 3 is a plan view of the device; Fig. 4 is another embodiment in plan view; Fig. 5 is a principle perspective view; Fig. 6 shows a section and Fig. 7 is a plan view of a development of the device according to the invention.
    The connection device for reinforced concrete slabs 1 shown in the drawings on a wall or ceiling construction 2 has an insulating body 3 for thermal insulation and a reinforcement part 4. The reinforcement part 4 consists in the tension zone of closed loops 4 'of, for example, fiber plastic for connection to the plate reinforcement and in the bending pressure push zone of differently profiled elements 4 " made of ultra-high-strength concrete (UHPFRC - Ultra High Performance Fiber Reinforced Concrete). The ends of the loops 41 are engaged with U-shaped brackets 5 of the connection reinforcement. I I · fl 4 • r '* 5 * - • * * * · · i
    Compared to stainless steel reinforcing bars, the invention enables lower cross-sectional areas and significantly reduced heat loss as well as a high adaptability to the load capacity due to different loop geometries. According to the invention, an endless loop, for example made of CFK or GFK, can be provided for the transmission of the tensile forces. The production of the loop can in particular be carried out with longitudinally oriented fibers in the loop direction, which are wrapped by a 90 ° twisted fiber layer, whereby sufficiently high transverse compressive strength is achieved. The formation of the loop allows power transmission despite the poor bond between the concrete and the loop. By changing the loop geometry, the carrying capacity can be easily adapted to the respective requirements. The most important influencing parameters are the loop height and the loop radius. With these two sizes, the deflection stresses on the surrounding concrete and thus also the transverse compressive stress on the loop are controlled. The UHPFRC pressure elements located at the extreme pressure edge provide a large internal lever arm which minimizes the forces acting on the supporting elements. FIGS. 3 and 4 show differently designed connection devices according to the invention. · »4 ··· * ·

    In the context of the invention, the thermal insulation performance can be significantly increased by the use of high performance materials UHPFRC and CFK / GFK. By forming a released compression belt of tapering UHPFRC elements, the required concrete volume and at the same time the heat loss surfaces can be minimized.
    In order to reduce the load transfer area between normal concrete and bending pressure thrust elements 4 " can enlarge these UHPFRC elements at the ends and preferably also profiled or with an upstanding triangular rib 4 '" be provided, as in particular Figs. 5 to 7 show. Through this "dog bone" shape, the heat conduction is kept low.
    Due to the extremely high tensile strength of CFRP / GFRP, the cross sections of the tension elements 4 'can be reduced in such a way that the heat insulation body is hardly interrupted. The heat conduction through the tension member is greatly reduced compared to stainless steel due to the very small heat transfer surface in total.
    Furthermore, the construction according to the invention enables an economic gradation of the load capacity. For example, with a flexural strength in the range of, for example, 50 kNm / m, twice the equivalent thermal resistance (insulation thickness, e.g., 8 cm) over existing products is expected. These excellent features result mainly from • * * * * • • • * • * '' / / ** ** * * * * * * * * * * * * * * * * * «« «* f the use of materials with very high strengths, whereby small cross-sections are required and thus the heat-insulating body is only slightly weakened.
    Another great advantage of the invention can be found in the production of insulating baskets. All welding work, which is required for the previously used products, is eliminated. Since the assembly is simplified, especially labor costs can be greatly reduced.
    The invention is intended to enable use in passive houses. A prerequisite for the passive house standard is an annual heating requirement of 15 kilowatt hours per m2 per year, which means a considerable energy saving compared to the low-energy house.
    By using the high strength CFRP material in the tensile area and UHPFRC in the pressure area and the corresponding savings in steel results in a significant improvement in the environmental sustainability of the product, since the energy required for the production of 1 m3 UHPFRC only 5% of the energy required for the production of the same amount of steel with the same compressive strength.
