Definitions

  • the present invention relates to a method for reinforcing concrete slabs in the range of support elements, in particular columns and support walls, with reinforcing elements, each consisting of a longitudinally stable flexible band-shaped base body, whose two end portions are each formed as a loop which in the relaxed state of a Have width a and which are introduced into the concrete to be reinforced plate.
  • the concrete slabs which can be designed as floor slabs on which supporting elements, or as ceiling slabs, which are supported by supporting elements, can be selectively reinforced by reinforcements or other reinforcing elements known are, for example, reinforcing baskets, which are embedded in the concrete to be concreted. All these reinforcing elements have the goal of being able to initiate the support forces acting through the supports or supporting walls on the concrete slab in the best possible way in the concrete slab in order to avoid local overloading or even punching of the columns by the concrete slab.
  • the concrete plate holes are mounted, which are arranged correspondingly obliquely, and in which tie rods are inserted, which are provided on the concrete plate on both sides projecting ends with anchor heads, which supported on the respective surface of the concrete slab are.
  • the tension element can be tensioned by appropriately equipped anchor heads, the hole can be filled with a mortar-like mass.
  • tie rods are used in accordance with appropriate holes in the concrete slab, which are designed dowel-like. But these have the disadvantage that in many cases the power transmission is not optimal, since the force application points are not exactly defined.
  • the object of the present invention is therefore to provide a method for reinforcing concrete slabs in the region of support elements, with which reinforcing elements, each consisting of a longitudinally stable flexible band-shaped base body, and whose two end portions are each formed as a loop, in an optimal manner can be used in the concrete to be reinforced plate, and with which the forces can be optimally absorbed.
  • the solution of this object is achieved in that in the concrete plate for each reinforcing element, a bore is mounted, which is inclined from the pressure side surface inclined towards the corresponding support member, and having a diameter d, which is smaller than the width a the relaxed loop that the drilled end surface of the bore is drilled out that one of the loops of the reinforcing member is compressed and inserted through the bore until this loop reaches the bore and widens that at least the drilled end portion of the bore with a mortar-like Mass is filled and that the other loop of the reinforcing element is fixed in an anchor head, which is supported on the pressure-side surface of the concrete slab.
  • the anchoring elements can be inserted from one side into the concrete slabs, the force absorption area is precisely defined, so that an optimal reinforcement is guaranteed.
  • the bore is performed continuously through the concrete plate, and the boring of the pressure-side surface of the concrete plate opposite surface is performed, which simplifies the production of the bore for receiving the reinforcing element, but requires that the concrete slab of accessible from both sides.
  • the filling of the hole with the mortar-like mass is carried out by an injection process.
  • a further advantageous embodiment of the inventive method is carried out in that the reinforcing element is tensioned after curing of the mortar-like mass and after attachment to the anchor head.
  • the desired voltages can be obtained thereby, on the other hand, it is also possible to retighten a reinforcing element inserted appropriately into the concrete slab even after a prolonged period of use.
  • a simple connection between the anchor head and reinforcing element is obtained in that the anchor head is equipped with a bolt which is inserted into the other loop of the reinforcing element.
  • the reinforcing elements inserted into the holes are mounted in the concrete plate in such a way that the inclination angle ⁇ with respect to the pressure-side surface is about 30 ° to 60 °.
  • a band of carbon fiber reinforced plastic is used as the reinforcing element, which on the one hand enables a large force absorption and on the other hand allows easy handling, in particular also with regard to the weight of the respective band.
  • reinforcing elements are corrosion resistant and fatigue resistant.
  • Fig. 1 is a concrete plate 1 can be seen, which is supported by a support member 2.
  • This support member 2 may for example be a support, but it may also be a support wall or the like.
  • the concrete plate 1 is reinforced in the area of the support element 2 in a known and not shown manner with appropriate reinforcements, for example by so-called reinforcement baskets.
  • Such a concrete plate 1 can be additionally reinforced in the region of the support elements 2.
  • holes 3 are mounted in the concrete slab. These bores 3 are arranged inclined from the pressure-side surface 4 of the concrete slab 1 at an angle ⁇ against the corresponding support element 2. The angle ⁇ can be about 30 ° to 60 °.
  • These bores 3 have a diameter d, the end side 5 of the respective bore 3 facing away from the pressure-side surface 4 is drilled to a larger diameter than the diameter d. This trained as a blind hole 3 with the drilled end portion 5 ends below the upper reinforcement layer of the concrete slab 1, a "violation" of the same is thereby excluded.
  • a concrete plate 1 can be seen, which, as in Fig. 1 is shown supported by a support member 2.
  • the holes 3 are passed through the concrete plate 1 in this illustrated embodiment, these holes 3, if the accessibility of this allows, can be attached from both sides of the concrete slab 1, the pressure-side surface 4 opposite end portions 5 can be drilled on the pressure-side surface 4 opposite surface 6 of the concrete slab.
  • the positions of the reinforcement layers can be detected by known methods, so that the holes can be passed through spaces of these reinforcement layers.
  • a reinforcing element 7 consists of a longitudinally stable flexible band-shaped main body 8, whose two end portions are each formed as a loop 9 and 10 respectively. In the relaxed state, both loops 9 and 10 have a width a which is greater than the diameter d of the respective bore 3.

The reinforcing element 7 can then be inserted into the bore 3, as shown in FIG Fig. 3 is apparent.
  • a respective reinforcing element 7, as it is Fig. 3 has been described, in a corresponding manner in a bore 3 according to Fig. 2 be introduced.
  • the respective reinforcing element 7 is inserted as far into the corresponding hole 3, until the one loop 10 enters the drilled end region 5. In this end region 5 then this loop 10 expands again to a width which is greater than the diameter d of the bore. 3
  • the drilled end region 5 and at least the adjoining region of the bore 3 is then filled with a mortar-like mass 11.
  • This can be done for example in a known manner by injecting this mortar-like mass into the bore 3.
  • this other loop 9 of the reinforcing element 7, which protrudes from the concrete slab 1 is fastened to a respective anchor head 12.
  • This anchor head 12 has in a known manner a bolt 13 which can be inserted into the other loop 9 of the reinforcing element 7 and which can also be moved in a known manner by means of clamping means 14 such that the reinforcing element 7 is tensioned.
  • clamping can be achieved in a known manner via a mounted on the anchor head additional device, which is hydraulically driven, for example.
  • other suitable anchor head types could be used.
  • the remaining area of the bore 3 can still be filled with a mortar-like mass 11.
  • This mortar-like mass may have a different composition and / or consistency than the mortar-like mass, with which the drilled end portion 5 is filled.
  • Such a hole for a concrete plate has a thickness of about 300 mm, for example, has a total length of 550 mm.
  • the boring of the end region 5 is carried out over a length of 100 mm, for example.
