Definitions

  • the invention relates to a seat and / or stair step for grandstands according to the preamble of claim 1.
  • a seat and / or stair step which has three projections on one side which cooperate with corresponding recesses of seat and / or stair steps arranged next to it in such a way that the steps can be aligned with one another.
  • the projections are each of circular cross-section and are brought into engagement with the corresponding, likewise circular recesses of adjacent steps by moving seat and / or stair steps to be arranged next to one another.
  • a disadvantage of such an arrangement is that the two steps to be arranged next to one another must be completely and flush aligned with one another before the projections and the respectively associated recesses are engaged, in order to be able to insert the projections into the respective recesses.
  • this shifting process it is inevitable that the bed or the binder on which such a seat and / or stair step is to be arranged is pushed into the gap between the adjacent step elements, so that the latter is not complete and flush can be pushed together. In this case, there remains a gap in which dirt can accumulate or through which liquid or moisture can enter or exit.
  • the object of the invention is to provide a seat and / or stair step of the type mentioned at the outset, which enables simple and precise laying, wherein individual seat and / or stair steps to be arranged next to one another should be able to be connected directly and flush to one another.
  • At least one further recess is provided laterally in the seat and / or stair element, which is or are elongated and extends or extends approximately vertically.
  • the at least one further projection and a recess provided in the adjacent seat and / or stair step can be displaced vertically in this recess.
  • the further projections of the finished part come into contact with the final assembly at least at one end of the respectively assigned recess.
  • Such a configuration of the recess makes it possible for the first projection to be introduced into the first recess in a pivoted form of the seat and / or stair step and for the step pivoted upwards to be pivoted downward only in the fully engaged, axial end position .
  • the further projection comes into contact with one end of a recess in such a way that the seat and / or stair steps arranged next to one another can be aligned flush with one another in the desired manner.
  • a simple and precise laying of the seat and / or stair steps is thus possible, with a direct and flush lining up of the individual seat and / or stair steps being ensured.
  • polymer concrete for the seat and / or stair treads results in a light installation weight which greatly reduces the stress on the installation personnel.
  • a lighter installation weight also enables more efficient installation. Elaborate hoists are not required such.
  • the production from polymer concrete enables compliance with very low tolerances. This enables installation with fewer "measuring points", which further reduces the effort.
  • the further recess (s) are open at the bottom and are designed such that the projection associated with a further recess can be inserted into the respective recess from below and upon final assembly of the finished part at the upper end of the respective one Recess to the system.
  • a further advantageous embodiment is characterized in that the further recess (s) is closed circumferentially and is or are designed such that the finished part, when the further projection rests on the respective upper end of the associated recess, of an adjacent one located in its end position Finished part is pivoted upwards relative to its end position and is in its end position when the further projection abuts the respective lower end of the same recess.
  • the front end of the horizontal leg is flush with the front of the vertical leg of the prefabricated component located below. This prevents a protruding edge and the formation of drip noses. It is also not possible to tear the front edge of the prefabricated part out of the concrete bed by grasping it.
  • At least one projection is formed at the upper end of the vertical leg, which cooperates approximately appropriately with the recess on the underside of the horizontal leg of the prefabricated part arranged below. Precise alignment of the finished parts can therefore also take place in the direction of the horizontal leg if they are sunk into the soft surface.
  • the projections and the recesses are conically shaped, so that there is an automatic centering when interacting and mortar or sand residues do not significantly hinder the fitting.
  • the horizontal and / or vertical legs are shaped like a bowl with a cavity facing downwards or backwards.
  • This finished part can therefore be manufactured with a relatively small thickness, the reinforced wall (shell edge) ensuring sufficient rigidity.
  • the shell shape also has the advantage that an effective bond with the concrete can take place.
  • This composite is further strengthened by an embodiment of the invention, according to which the rear side of the vertical leg has a horizontally extending, elongated, preferably triangular or trapezoidal depression or groove in the lower region.
  • the horizontal leg is relatively deep, particularly in the case of seat steps, it can be expedient according to one embodiment of the invention if at least one rib running parallel to the horizontal leg is formed on the underside of the horizontal leg.
  • the rib forms a reinforcement of the seat and contributes to better anchoring in the concrete.
  • one embodiment of the invention provides that a foundation support is provided which is shaped like the vertical leg of the prefabricated part and has a widened contact area.
  • the upper edge of the foundation support is provided with a projection similar to the vertical leg of the L-shaped prefabricated part, so that a form fit can take place with the underside of the horizontal leg.
  • a hollow block step for attachment to the top of the horizontal leg near the vertical leg is provided according to one embodiment of the invention, the depth of which is significantly smaller than the length of the horizontal leg. It is preferably about half of the horizontal leg.
  • the hollow block step is preferably box-shaped and can be attached, for example, by gluing to the steps.
  • the surface of the finished part is water-repellent, but non-slip. At least the front end of the horizontal Thighs are sufficiently rounded so that users' clothing is protected.
  • An L-shaped prefabricated part 10 made of polymer concrete has a vertical leg 12 and a horizontal leg 14. At least the front or upper side of the leg 12, 14 has a smooth surface without the possibility of water absorption. In addition, polymer concrete is absolutely frost and de-icing salt resistant.
  • the legs 12, 14 are shaped like a shell with a cavity 16 or 18 facing backwards or downwards. A circumferential edge 20 or 22 remains, which has a correspondingly greater thickness and thus the Legs 12, 14 gives the necessary stability.
  • the edge 22 of the horizontal leg 14 is provided in the rear area on the sides with a trapezoidal recess 24.
  • On the underside of the seat of the horizontal leg 14 is approximately in the middle of the cavity 18th a longitudinally extending rib 26 is formed, which enables an improvement in stability and a better anchoring in the concrete.
  • the vertical leg 12 is shaped at an angle of less than 90 ° relative to the horizontal leg 14. Accordingly, the rear wall in the cavity 16 is inclined to the vertical, so that an effective anchoring in the concrete is also achieved at this point.
  • This is further reinforced by a groove with a trapezoidal cross section in the transition between the horizontal leg 14 and the vertical leg 12 at the rear, as shown at 28.
  • a rounded transition 30 is provided on the front side between the vertical leg 12 and the horizontal leg 14. The front edge of the horizontal leg 14 is also clearly rounded, as shown at 32.
  • two spaced projections 34 are formed on the upper side of the vertical leg 12, which cooperate with a recess 36 on the underside at the front end of the horizontal leg 14 of the prefabricated part arranged above.
  • a projection 40 of circular circumference On one side of the horizontal leg 14 in the area of the vertical Leg is formed a projection 40 of circular circumference, which fits into a corresponding recess 42 on the opposite side of an adjacent finished part 10. This can be seen in FIG. 6.
  • Fig. 4 it can be seen that on the underside of the horizontal leg 14 has a reinforcement in the corners at the front end, as shown at 46. As shown in FIGS. 10 and 11, this can have two downwardly projecting “feet” 60 for improved anchoring in the concrete.
  • FIG. 7 shows a partial side view of an L-shaped prefabricated part 10 'with a vertical leg 12' and a horizontal leg 14 ', which largely resemble the prefabricated part according to FIGS. 1 to 6.
  • a circumferentially circular projection 50 is formed on one side at the front end of the horizontal leg, which cooperates with a correspondingly shaped recess in the adjacent prefabricated part, similar to the interaction of the projection and 6.
  • a downwardly open vertical U-shaped elongated recess 52 is formed on one side, into which a projection of the adjacent finished part engages when the finished parts are placed against one another, which increases
  • the prefabricated part is tilted upwards when the projection 50 and the corresponding recess have already been engaged.
  • the finished part 10 'to be laid is then laid, the projection 50 acts as an axis of rotation until the projection of the adjacent finished part abuts the upper end of the recess 52. Then the two finished parts are aligned with each other.
  • the abutment of the projection of the adjacent prefabricated part in the recess 52 is indicated by dashed lines at 54.
  • the bottom 8 shows how a number of prefabricated parts 10 are used to lay a row of seat steps.
  • the laying takes place on an embankment 60, which is provided with a gravel fill 62. Concrete 64 is applied to the gravel fill, into which the individual finished parts 10 are sunk.
  • the top step can be formed exclusively by a horizontal leg 60, which is also designed as a finished part and has a shape similar to the horizontal leg of the finished part 10.
  • the lower seat step 10 is supported by a foundation support 68, which has projections on the top corresponding to that vertical leg 12 of the finished part 10. At the lower end, the foundation support 68 is provided with a widened contact surface 70 on both sides.
  • the foundation support 68 is longer than the height that each horizontal leg of the lower seating level has over a paved surface 72. This provides secure support the seating level. This design also prevents the foundation support from being removed by hand.
  • FIG. 9 shows the arrangement according to FIG. 8 in perspective. It can be seen that the individual finished parts 10 are arranged offset from level to level. A projection 34 cooperates with the horizontal leg of a prefabricated part 10, while the other cooperates with the adjacent prefabricated part.
  • hollow block steps 74 are placed on the horizontal legs or on the seat surfaces, which can have a box-shaped profile. The open side faces the seat. The hollow block steps 74 are placed against the horizontal leg and laid over a predetermined width, so that a staircase is created in the area of the seat steps.
