Definitions

  • the present invention relates to a stop body for concrete formwork mentioned in the preamble of claim 1. Art.
  • a stop body for concrete formwork which has a base body with a circular cylindrical outer wall, wherein the base body has a base for attachment to a component.
  • the outer wall forms a stop surface for concrete formwork.
  • a sleeve arranged, which has a passage opening for a fastening element and which defines a fastening axis of the stop body.
  • stop bodies are that it can lead to visibility problems when using them for column formwork, since the round stop body fill the corners between two shuttering walls respectively and thus little space is available, could flow into the concrete.
  • the object of the present invention is to provide a stopper body, which ensures good Wegsamkeit for flowing concrete when applied in the corners between two formwork walls.
  • an inventive stop body with the features of claim 1. Accordingly, a plurality of coaxial with the axis (or mounting axis) extending elongated stop points are provided, of which form at least two stop locations stop pairs, which lie in a common plane. Between the stop points thus results in an axially extending space for concrete.
  • this inventive design of the stopper body has a good Wegsamkeit for, the stopper body flowing around concrete, whereby the stopper body in the finished concrete column remain visually inconspicuous and thus there are no optical impairments more is coming. At the same time, however, a good functionality in terms of stability of the stopper body is still achieved over the shuttering walls.
  • each case two of the elongate stop locations form a stop pair which is arranged on a stop arm extending from a center, whereby the stability and robustness of the trough-shaped stop elements is increased.
  • the paired elongated stop points are arranged on trough-shaped stop elements, which are arranged at the center remote from the ends of the stop arms.
  • This configuration results in a high stability of the stop points coupled with a certain elasticity, which counteracts an unwanted breaking off stop points when striking a formwork stop.
  • the trough-shaped stop elements which run parallel to the axis or attachment axis, offer a sense of ease for flowing concrete.
  • the elongated abutment points lie on an enveloping circle which has a radius to the axis.
  • two adjacent stop points of the two stop arms lie in a common plane and can thus be used to support a shuttering wall.
  • a very stable support can be achieved if a support arm extending from the center is provided, which encloses an angle between 110 ° and 130 ° with the at least one stop arm.
  • the fastening part is arranged on the support arm, on which a fastening element can be arranged in order to fix the stop body to a component.
  • At least one support element protrudes from the support arm, as a result of which the forces can be transferred better and thus higher loads can be absorbed.
  • the stopper body 10 has a base 12 for attachment to a component, such. As a base plate, concrete ceiling or the like on. At least one approach surface is provided on the base 12 for this purpose.
  • the stopper body 10 has a z. B. sleeve-shaped fastening part 11, which defines an axis A and which has a passage opening 13 for a fastening element (not shown in the figures). Around the passage opening 13 around an abutment 14 is formed for the fastener.
  • the stopper body 10 has three branching off from a center 15 arms. Of these arms, two are designed as stop arms 18 and one as a support arm 19.
  • the stop arms 18 go over at their ends facing away from the center 15 in trough-shaped stop elements 17, whose outer edges extending in the axial direction in each case form first stop locations 16a and second stop locations 16b.
  • the stop arms 18 are at an angle alpha of 120 ° to each other, wherein also angle alpha in the range of 110 ° to 130 ° are possible. Between the elongated abutment points 16a, 16b axially extending free spaces are spanned, which provide a Wegsamkeit for flowing concrete.
  • the fastening part 11 with the passage opening 13 and the abutment 14 is arranged on the support arm 19, however, the fastening part 11 with the passage opening 13 and the abutment 14 is arranged. Furthermore, two support elements 20 are provided at the free end of the support arm 19, the feet 23 have to be supported on a component 50.
  • the support elements 20 are curved in a quarter-circle parallel to their extent in the direction of the axis A.
  • the support arm 19 is at an angle beta of 120 ° to the adjacent stop arm 18, wherein also beta angles in the range of 110 ° to 130 ° are possible.
  • the abutment points 16a, 16b designed as abutment edges and extending in the axial direction are all located on a common enveloping circle H whose center lies in the axis A and to which it has a radius R.
  • the radius R therefore also corresponds to the radial distance of the abutment points 16a, 16b to the axis A.
  • the geometry of the abutment points 16a, 16b with respect to the axis A is further selected such that the effective levers L1 of the abutment points 16a, 16b to a line perpendicular to the axis are preferably the same length as the effective lever L2 of the mutually adjacent abutment points 16a Both stop arms 18.
  • the stopper body 10 is thereby automatically aligned during infestation.
  • the median lines M of the trough-shaped stop elements 17, which run perpendicular to the axis A, are preferably at a right angle to one another.
  • Fig. 2 is the stopper body 10 on a component 50, such.
  • a component 50 such as a concrete ceiling, fastened, wherein the fastener was not shown for reasons of clarity.
  • At the stopper body 10 are two at a right angle to each other standing shuttering walls 30, which are respectively supported on the stop points 16 a, 16 b of a stop arm 18.
  • the formwork was also already poured with concrete 40, which envelops the stopper body 10 as far as possible. Only the stop edges or stop locations 16a, 16b are still visible after removal of the formwork.
