Definitions

  • connection cage having an insulating body for thermal insulation and a reinforcement structure penetrating the insulating body, the reinforcement structure having an upper reinforcement profile and a lower reinforcement profile which protrude from the insulating body.
  • connection baskets In order to carry out such a connection with thermal insulation, so-called connection baskets were developed. These are usually formed with an insulating body, through which reinforcing profiles are passed, in order to connect a concrete slab and the other end of the reinforcing profiles, for example a building ceiling, to one end of the reinforcing profiles, so that the insulating body is arranged between them for thermal insulation. At least one upper reinforcement profile is often provided as a tension chord for the transmission of tensile forces and at least one lower reinforcement profile is provided as a compression chord for the transmission of compression forces. Horizontal connection reinforcements for moment transfer usually connect to the upper and lower reinforcement profiles.
  • horizontal bars running parallel to the respective longitudinal axis of the reinforcement profile are often welded to the upper reinforcement profile and the lower reinforcement profile.
  • the shear force is transmitted via local bending of the reinforcement profiles.
  • several horizontal bars welded to the upper and lower reinforcement profile can be included with stirrups. This prevents it from breaking out of the concrete.
  • connection baskets are often very well suited to absorbing and transmitting moments, but are usually less efficient in terms of shear force transmission.
  • connection basket of the type mentioned at the outset, which enables a high level of practical use.
  • the upper reinforcement profile and/or the lower reinforcement profile in a respective cross section has a profile shape that is open transversely to a height direction, preferably in a longitudinal direction, of the insulating body.
  • connection cages are often very well suited for absorbing and transmitting moments, but are generally less efficient with regard to dissipating transverse forces or are not optimized with regard to such.
  • connection baskets there is often oversizing at positions at which a particularly pronounced transmission of lateral forces is required. This regularly generates unnecessary material and cost expenditure.
  • connection cages which are optimized with regard to an efficient transmission of lateral forces
  • an advantageous use optimization can be achieved. It has been shown that a pronounced transfer of lateral force or load increase can be achieved if the upper reinforcement profile and/or lower reinforcement profile has a profile shape that is open transversely to the height direction, preferably in the longitudinal direction or longitudinal axis direction, of the insulating body. A momentary transfer is not in the foreground.
  • a connection reinforcement aligned in the longitudinal direction of the reinforcement profiles, in particular horizontally, adjoining the upper or lower reinforcement profile is not required. However, it is possible that such is additionally provided. For efficient production, it is favorable if the upper and lower reinforcement profiles are designed with the same profile shape.
  • the top and bottom reinforcement profiles may have different orientations of the opened profile shapes, although a substantially the same orientation is preferred.
  • the upper and lower reinforcement profile in the respective cross section each have a profile shape that is open in a longitudinal direction of the insulating body.
  • the longitudinal directions of Insulator, to which an alignment of the profile shapes refers, can be parallel or antiparallel to one another, with a parallel alignment or an identical alignment of the profile shapes of the upper and lower reinforcement profile being preferred.
  • Height direction usually designates a direction orthogonal to the longitudinal axis of the insulating body and orthogonal to the longitudinal axis of the upper or lower reinforcement profile.
  • the upper reinforcement profile and lower reinforcement profile are generally arranged at a distance from one another in the height direction, it being possible for them to be arranged laterally offset from one another in the longitudinal direction of the insulating body. It is preferred if the upper and lower reinforcement profiles are arranged in such a way that they are arranged essentially on a line aligned in the vertical direction.
  • the upper and lower reinforcement profiles are preferably aligned essentially parallel to one another.
  • the longitudinal direction of the insulating body usually designates those directions which are parallel to a longitudinal axis of the insulating body.
  • the profile shape of the upper or lower reinforcement profile is usually implemented in that the reinforcement profile has a profile contour in the respective cross section, which is formed with two directly or indirectly connected segments, which form an opening in the profile contour, in particular to an area surrounded by the profile contour .
  • the opening is aligned transversely to the height direction, preferably in a longitudinal direction or longitudinal axis direction, of the insulating body.
  • the profile shape is essentially double-T-shaped, I-beam-shaped, V-shaped, C-shaped or U-shaped.
  • two legs forming the segments can be implemented in a practical manner, which form the opening oriented transversely to the vertical direction.
  • the upper reinforcement profile and the lower reinforcement profile are connected to one another by one or more transverse bars which are usually spaced apart from one another.
  • the function of the crossbars can thus be that known from the prior art stirrup connections or hook connections in the context of a horizontal connection reinforcement welded to reinforcement profiles.
  • the upper and lower reinforcement profile, which is connected by at least one crossbar, is also referred to as a reinforcement profile pair.
  • the crossbar or crossbars are preferably arranged outside of the insulating body and preferably at a distance from it.
  • the upper reinforcement profile and the lower reinforcement profile are connected to one another along their longitudinal axes by a plurality of transverse bars spaced apart from one another, with the transverse bars preferably being aligned essentially parallel to one another.
  • the transverse rods are usually located on the same side of the insulating body for reasons of simple production.
  • the respective transverse bar is aligned essentially orthogonally to the longitudinal axis of the upper reinforcement profile and/or lower reinforcement profile connected by the transverse bar.
  • an oblique arrangement of the transverse rods is also possible, in which case they can then preferably be arranged in parallel.
  • the respective transverse bar is connected to the upper reinforcement profile and lower reinforcement profile in the region of its ends.
  • the crossbar(s) are preferably connected to the reinforcement profiles in a materially bonded manner, in particular by welding or gluing.
  • the transverse bar can end flush with the ends of the upper and lower reinforcement profiles in the longitudinal direction of the reinforcement profiles. End areas or ends usually designate those areas or sections of a respective reinforcement profile which have a maximum distance from the insulating body along the longitudinal extent of the reinforcement profiles.
  • a first transverse bar is connected to the end regions of the upper and lower reinforcement profiles and a further transverse bar is connected further inwards towards the insulating body with the upper and lower reinforcement profiles.
  • An outer transverse bar or end bar can be arranged in the area of one end of the reinforcement profile in the longitudinal direction, whereas an inner transverse bar is arranged in an area close to the insulating body. This can be implemented on one or two opposite sides of the insulating body.
  • at least one crossbar is in is connected to an outer third of a length between the end and the insulator transition of the respective upper and lower reinforcement profile.
  • the crossbar arrangement described applies to at least one, in particular a majority, preferably all, of the pairs of reinforcement profiles.
  • the respective crossbar connecting the upper and lower reinforcement profile is connected to the upper or lower reinforcement profile on a side opposite the opening of the profile shape or profile contour of the upper and/or lower reinforcement profile.
  • the upper or lower reinforcement profile is formed with a C-shaped profile
  • the crossbar is connected to the reinforcement profile on a base surface of the profile shape from which the legs of the C-shape protrude.
  • the legs of the C-shape, which form the opening, are preferably aligned essentially in a longitudinal direction of the insulating body.
  • crossbars which connect the same upper and lower reinforcement profile or reinforcement profile pair to one another are connected to the respective reinforcement profile on the same reinforcement profile side. It is favorable if the respective transverse bar connects the upper and lower reinforcement profiles of a respective reinforcement profile pair to one another on the same reinforcement profile side. It is advantageous if the openings of the upper and lower reinforcement profile of a respective reinforcement profile pair are directed essentially in the same direction. It has proven useful if crossbars connecting different pairs of reinforcement profiles are arranged on the same side of the respective reinforcement profiles. This enables greater efficiency in production. It is expedient if the openings of the upper reinforcement profiles or lower reinforcement profiles are directed essentially in the same direction.
  • the reinforcement structure has the aforementioned configuration on at least one side, preferably on two opposite sides, of the insulating body - i.e. the connection cage, in particular on the respective side, at least one or more upper reinforcement profiles protruding from the insulating body and at least one or more from the insulating body protruding lower reinforcement profiles, wherein the upper and/or lower reinforcement profiles in a respective cross section have a profile shape that is open transversely to the height direction, preferably in a longitudinal direction, of the insulating body. At least one upper and one lower reinforcement profile can then be connected to one another on at least one or both sides of the insulating body with one or more transverse rods, as explained in particular above.
  • the upper and lower reinforcement profiles extend completely through the insulating body, so that they protrude from the insulating body on opposite sides of the latter.
  • a section of the upper or lower reinforcement profile can be encased by the insulating body.
  • tension and pressure reinforcement elements are attached to the reinforcement profiles. These can be attached in a material-to-material, non-positive and/or form-fitting manner. In order to achieve a sufficiently high level of lateral force transmission, however, these are not absolutely necessary.
  • the reinforcement profiles and/or crossbars are made of a non-rusting material, for example stainless steel. It can be advantageous to use sections of the upper or lower reinforcement profiles made of a non-metallic material,
  • fiber-reinforced for example fiber-reinforced, in particular glass-fiber-reinforced or basalt-fiber-reinforced plastic.
  • the distance between the upper edge of the upper reinforcement profile and the lower edge of the lower reinforcement profile of a respective pair of reinforcement profiles is 50 mm to 150 mm, in particular 90 mm to 120 mm, preferably about 110 mm. It is expedient if immediately adjacent upper or lower reinforcement profiles or adjacent pairs of reinforcement profiles are at a distance of 50 mm to 1500 mm, in particular 70 mm to 600 mm, preferably 100 mm to 200 mm.
  • the crossbars are usually outside of the insulator and are usually spaced from it.
  • the transverse bars usually have a diameter of between 5 mm and 21 mm, for example between 7 mm and 15 mm, preferably around 10 mm.
  • the diameters of the crossbars can be the same or different, for example 8 mm and 10 mm. It has proven useful if the insulating body has a width of between 50 mm and 210 mm, in particular 70 to 100 mm, preferably about 80 mm. The width runs orthogonally to the direction of the longitudinal axis and the direction of height of the insulating body, generally essentially parallel to the longitudinal axes of the reinforcement profiles.
