Definitions

  • the invention relates to a reinforcement element for concrete construction in the form of a Head bolt, which consists of a rod-shaped section with a terminal Cross-sectional expansion exists.
  • Such head bolts are mainly used for the transmission of pressure and Shear forces used, but can also transmit tensile forces. Mainly they are used as shear reinforcement or punching shear reinforcement for concrete components used, also as a pressure or transverse force rod in insulating bodies between a building ceiling and a protruding balcony slab.
  • reinforcement bars have been used, especially when it comes to corrosion resistance or low heat conduction, also from glass fiber reinforced Made of plastic. It is thermosetting plastic, which is used to achieve the desired strength a glass fiber content of about 50% to 80% having. Since thermoset cannot be deformed afterwards, reinforcement elements have so far been used made of glass fiber reinforced plastic only in the form of rods constant cross section.
  • the present invention is based on the object of a reinforcement element in the form of a headed bolt, in which at least the head, So the final cross-sectional expansion made of glass fiber reinforced plastic consists.
  • the head bolt should pull in due to high force absorption also distinguish in the printing direction and be rationally producible.
  • the cross-sectional expansion has sleeve-like extension extending along its axial bore, in a length that is at least about three times, preferably corresponds at least approximately to four times the diameter of the bore. This gives a large positive engagement surface between the two Share and therefore a correspondingly high power transmission.
  • the sleeve-like extension in Direction of the cross-sectional expansion has an increasing wall thickness, is conical and towards its end at an angle of less than 90 degrees, especially less than 60 degrees in the cross-sectional expansion transforms.
  • the present invention also relates to an insulating body, which is equipped with the above-mentioned reinforcement elements, and between two components to be insulated, in particular a building ceiling and one Balcony slab, is installed.
  • the corrosion-resistant properties come here of glass fiber reinforced plastic and its low thermal conductivity particularly advantageous.
  • the reinforcement element according to the invention can in the insulating body for the transmission of tensile, compressive and transverse forces be used.
  • Figures 1 to 3 each show only one end - designed as a head a reinforcement element. The other end can look the same, can but also be designed differently or run out as a normal reinforcing bar.
  • the reinforcement bar or its rod-shaped section shown is 1 designated, the terminal cross-sectional expansion with 2. As you can see, acts the cross-sectional expansion 2 is an independent part. It has no longer the conventional shape, but a sleeve-like extension 2a, with which it also encloses the rod-shaped section 1.
  • the profiling 4 and 5 is formed by threads. It would therefore be possible to extend the cross-section 2 with its sleeve-like Screw extension 2a onto the rod-shaped section 1 and then connect both parts together. But it is usually cheaper that To insert the end of the rod-shaped section 1 into an injection mold and the cross-sectional expansion 2 with its sleeve-like extension 2a in spray molten state.
  • the sleeve-like extension 2a preferably also has on its outside a certain profiling in order to favor their later connection with the concrete. For this purpose, it has several successive, graduated in diameter Sections 6 and 7, their diameters in the direction of the cross-sectional expansion 2 gradually increases, then at an angle of less to transition into cross-sectional extension 2 as 60 degrees.
  • Fig. 1 the sections 6 are by a helical circumferential step separated from one another, while in FIGS. 2 and 3 the sections 7 by several circular steps are separated. Of course here are any other profiling is also possible.
  • insulating bodies 4 and 5 show the use of the head bolts described above for insulating bodies.
  • These insulating bodies are between a building ceiling and one protruding balcony slab installed to the heat flow between the two components to minimize. They are usually with reinforcement elements for transmission equipped with tensile, compressive and transverse forces.
  • an insulating body 10 can be seen is arranged between a balcony slab 11 and a building ceiling 12.
  • the Insulating body 10 contains, as usual, horizontally continuous in its upper region Tension rods 13, transverse force rods 14 running obliquely in the central region and pressure bars 15 running horizontally in the lower region.
  • Fig. 4 shows an alternative for the formation of the head bolts.
  • Fig. 5 shows the shear force rod with normal perpendicular to the rod axis End up.
  • the plastic used for the present application exists in the case the rod-shaped section 1 from about 50% to about 80% glass fibers, moreover made of thermoset plastic, in the case of the sprayed-on head part, i.e. the end part Cross-sectional expansion 2 and its sleeve-like extension 2a about 20% to about 60% glass fibers, otherwise made of thermoplastic.
  • Fig. 6 shows the vertical section through a bar 21, in which the four each perpendicular to each other and parallel to the outer sides of the beam 21 Head bolts 22 serve as a replacement for a bracket that is static dimensioned bending reinforcement that extends horizontally in the beam, to tie up.
  • FIG. 7 which is also a vertical section through shows a horizontally projecting bracket 32 connected to a column 31, the head bolts 33 serve to absorb the bending forces of the bracket 32 and transmitted to the column 31 or its reinforcement 34, the headed bolts Components usually referred to as anchors replace those in the upper one Bracket area under tension and in the lower bracket area under pressure become.
  • FIG. 8 also shows a rigid corner 41 in a vertical section shown, in which the head bolts 42 according to the invention are used to Brackets usually used at this point to replace as reinforcement.
  • FIG. 9 shows head bolts according to the invention 51, 52, which are arranged in a ceiling 54 supported on a support 53 are and here between an upper grid reinforcement layer 55 and a extend lower grid reinforcement layer 56.
  • the head bolts 51, 52 serve here as shear reinforcement or punching shear reinforcement elements and wear the forces between the slab and the column are trussed away from the column from the outside, so that the column cannot be punched through the ceiling becomes.
  • the diameter increases at the end favor Head the head bolts 51, 52 to transfer the force to the respective lattice reinforcement layers.
