Definitions

  • the invention relates to a device for connecting a tie rod with a Frame for holding grates.
  • Gratings are used to cover drainage channels, light or sewer shafts used.
  • the manholes or drainage channels are usually made of concrete.
  • To fix the grids on the shafts or channels are on these frames intended.
  • the connection between the frames and the concrete is made via Tie rod.
  • the well-known tie rods consist of a socket, which in a in the frames intended hole is inserted. To ensure a stable connection between tie rods and the frame, the socket is riveted to the frame. On the grate opposite side is a monier iron inserted into the socket, which with the socket is riveted. To screw the gratings to the tie rods, you can insert in the socket Internal thread may be provided.
  • the known tie rods for frames have one Series of disadvantages. First of all, the production is complex and consequently expensive. In addition, the tie rod is not releasably connected to the frame, so that an exchange of the frame or tie rod is not possible. Furthermore, one Cleaning the thread provided in the socket is only possible by burning out, since the dirt accumulated in the socket cannot run off. That too is Retaining force of the tie rod in the concrete is relatively low, since the iron is no means for Has increased holding force.
  • the invention seeks to remedy this.
  • the invention is based on the object to create a tie rod for frames, which is inexpensive to manufacture and in Assembly is easy. According to the invention, this object is achieved by a solvable Connection between the tie rod and the frame released.
  • the tie rod is inserted into the frame.
  • the tie rod preferably has wings which are arranged below on the frames Grasp tongues. Through the tongues and the wings is a simple and at the same time stable detachable connection created between tie rod and frame.
  • a projection is provided on the tie rod, which in a recess in the frame protrudes.
  • the tie rod is supported by this training at another point on the frame, which ensures increased stability is.
  • the tie rod has heads which are provided with holes in the Frame correspond. Through this correspondence, the heads dip into the Drilled holes partially assembled, creating an accurate Fixing the tie rod to the frame is guaranteed.
  • openings are provided in the tie rod. With the help of the perforations, the hardening of the tie rod in the concrete is increased, because when the tie rod is inserted into the liquid concrete, the openings are fills and ensures increased traction.
  • Teeth are preferably arranged on the tie rod. The teeth lead to one further increase in the tensile force of the tie rod after the concrete has hardened.
  • the length of the tie rod is variable. This is the Device can also be used with channels or shafts of different heights.
  • a nut is inserted into the tie rod, which is held releasably by supports.
  • the mother is the possibility created to screw a grating to the tie rod.
  • the nut has the shape of a plate in which the radial Thread slots are cut. This configuration makes it simple Guaranteed insertion of the nut into the tie rod.
  • the radially arranged slots a drain of water and dirt contained therein, so that contamination and thus inhibition of the screw function is prevented.
  • the tie rod is essentially a pressed part with a U-shaped profile made. Due to the production as a pressed part Material and production costs significantly reduced.
  • the frame 1 chosen as an exemplary embodiment consists of a multiply folded frame Metal strips.
  • a tie rod 2 is releasably attached.
  • Frame 1 and Tie rods 2 are made of galvanized material in the embodiment.
  • the frame 1 has an H-shaped cross section in the exemplary embodiment (FIG. 1). It is made of a metal strip, which is folded once by 180 °, so that Place two folded sections 111, 112 together. These together adjacent sections 111, 112 form a vertical leg 11 of the Frame 1 off. By kinking the free end of section 112 by 90 ° is a Leg 12 formed. The free end of the leg 12 is in the opposite Direction also bent by 90 °, so that the leg 12 is horizontal Section 121 and a vertical section 122.
  • Area of section 111 includes the frame 1 in the installed state the end of shafts or drainage channels facing the frame in order to ensure an exact To ensure that frame 1 is fixed on the shafts or drainage channels.
  • the frame 1 can also have an L-shaped cross section exhibit. In this case, frame 1 is on the shafts or gutters arranged without laterally embracing them.
  • a hole 13 is arranged in section 121 in leg 12 of frame 1.
  • two are on both sides of the hole 13 Tongues 14 from section 121 of leg 12 in the direction of tie rod 2 (Fig. 4].
  • a horizontal region 141 is formed at each of its free ends.
  • the leg 12 in its section 121 approximately each arranged between hole 13 and tongue 14, holes 16, the diameter is smaller than that of the hole 16 in the exemplary embodiment.
  • At the transition from horizontal section 121 to vertical section 122 of leg 12 is one Recess 15 provided (Fig. 3).
  • the tie rod 2 is made as a pressed part. It has a U-shaped cross section Profile, which is formed from two legs arranged parallel to each other, the are connected by a central part.
  • the tie rod 2 consists essentially a head part 21 facing the frame 1 and a head part 21 adjoining shaft 22 (Fig. 1).
  • the head part 21 is on its side facing the frame 1 with a plate 211 provided (Fig. 4).
  • the head plate 211 has a hole 212 which is assembled Condition aligned to the hole 13 of the frame 1 is arranged.
  • the top plate 211 has the longitudinal center line of the sides 1 arranged vertically Wings 213, which reach under the tongues 14 of the frame 1; the wings 213 rest the horizontal region 141 of the tongues 14.
  • the head plate 211 On the frame 1 facing On the side, the head plate 211 has heads 215 which align with the bores 16 of the frame 1 correspond.
  • On the legs of the head part 21 are at a distance from the head plate 211 on the sides facing each other support 216 is provided. in the Embodiments are the supports 216 by punching spherical layers Surveys realized.
  • the head part 21 On a parallel to the longitudinal center line of the frame 1 arranged side is provided on the head plate 211, a projection 214 which in the recess 15 of the frame 1 protrudes (Fig. 3).
  • the head part 21 On his facing away from the frame 1 At the end, the head part 21 has a base plate 217 (FIGS. 1 and 2). in the The embodiment is the base plate 217 from which the legs of the shaft connecting body punched out on three sides and 90 ° in the direction of Leg folded made. As a result, there is a recess in the base body 218 caused.
  • the shaft 22 of the tie rod 2 is substantially triangular on the legs Taper 221 arranged. On those continuing in shaft 22 Legs 222 teeth are arranged. In the exemplary embodiment, the teeth 222 are in provided at regular intervals. However, they can also be irregular be arranged. In the base body connecting the legs, the shaft 22 Openings 223 are provided. Through teeth 222 and openings 223 is an increased hardening between concrete and Tie rod guaranteed. As a result, can be exerted on the frame 1 even at high Forces secure fastening of the frame 1 with the help of the tie rods 2 become.
  • a nut 23 is held in the form of a plate by the supports 216.
  • the mother 23 has a hole 231 into which an internal thread is cut (FIG. 3 and 4).
  • Two slots 232 are cut radially to the hole 231 in the plate.
  • the slots 232 are diametrically opposed in the exemplary embodiment arranged and protrude into the hole 231.
  • the mother 23 points to the Legs of the head portion 21 adjacent sides chamfer 233, with which the Nut 23 rests on the supports 216 of the head part 21.
  • the nut 23 and the spherical segment-shaped supports 216 there is the possibility to clean the tie rod or nut after unscrewing one Fastening the grate serving screw and after removing the grate knock the nut 23 out of the frame in the direction of the base plate 217, if pulling out in the direction facing away from the base body is not possible is.
  • the nut 23 is only required if there is a grate with the frame or the Tie rod to be screwed. If a screw connection is not necessary, it can the mother 23 is eliminated. In addition, it is possible to replace others with one mother Locks for the grate provide a comparable holding force on the Exercise rust.
