Definitions

  • the lattice bars are fastened in the frame in different ways.
  • the bars are rigidly connected to the frame.
  • spacers are provided which allow a certain freedom of movement for the grille, which enables thermal compensation. This compensation option is important if the grating and frame are made of different materials.
  • a cross slot (5) in the spacer bolt (1) extends over the lattice bar (3) and positions it in the lattice frame (2).
  • the spacer pin engages in a recess (7) in the lattice bar (3) and thus prevents the lattice bar (3) from being pulled out of the lattice frame (2).
  • a paste-like plastic (9) can be inserted between the bolt slots (5) and tubular bars (3) through a longitudinal hole (8) after the lattice frame (2) has been fitted with bars (3) and spacer bolts (1). After the plastic (9) has hardened, a non-positive connection is made between the spacer bolts (1) and the lattice bars (3), so that the pipe spacing grid remains positioned and fixed in the lattice frame (2) for the subsequent operations.
