  • a landing sill 11 is provided in a floor portion of the landing doorway 2.
  • a door leg 12 is provided to a lower end portion of each landing door 7 inserted into the landing sill 11.
  • Such a landing door apparatus has a so-called ship-lap structure, in which the door side fire prevention members 8 oppose the vertical frame fire prevention members 6 and in which the door upper portion fire prevention member 10 opposes the top frame fire prevention member 9. Further, when warpage is generated in the landing doors 7 by fire, the door side fire prevention members 8 are engaged with the vertical frame fire prevention members 6, and the door upper portion fire prevention member 10 is engaged with the top frame fire prevention member 9, thereby preventing the landing doors 7 from getting out of place. Due to this construction, the requisite fire prevention performance is provided.
  • the above-described fire prevention structure can be easily applied to a new landing door apparatus.
  • it is necessary to replace all of the jamb 3 and the landing doors 7 or perform a large-scale additional installation work, resulting in an increase in time, labor, and cost.
  • it takes time and labor to perform installation and adjustment.
