- the sill part shield member 124 is attached to the lower part 110b of the hall door 110, and the sill part shield member 124 is moved from the base end 124a to the distal end 124b.
- the mounting position is adjusted within the range of the mounting hole 124c in the direction toward it.
- the degree of sealing between the lower part 110b of the hold door 110 and the sill 106 is adjusted to an optimal state.
- the optimum degree of sealing means that the gap formed between the hold door 110 and the entrance 104 is closed, the ventilation between the hoistway 102 and the elevator hall 103 is shut off, and the door pocket part is shielded.
- the material 123 is pressed against the side 105b of the three-sided frame 105, and the tip 124b of the sill shield 124 is pressed against the upper surface 106a of the sill 106 with a strength that does not hinder the opening and closing operation of the hold door 110. I do. If the curtain plate shielding material 122, the door pocket shielding material 123, and the sill shielding material 124 are bonded and fixed to the respective push plates 126, 128, and 130 in advance, mounting work can be performed easily. it can.
- the mounting holes 123b and 124c of the door pocket shielding material 123 and the sill shielding material 124 are formed in an oblong shape. Is formed. Therefore, before shipping from the factory, the door bag shielding material 123 and the sill shielding material 124 should be installed until they are temporarily fixed at the center of the mounting holes 123b and 124c, and the on-site work is limited to the adjustment work only. , Work on site can be reduced.
- the smoke shield device 120 including the door stop portion shielding material 121, the curtain plate portion shielding material 122, the door pocket portion shielding material 123, and the sill portion shielding material 124 is provided.
- the hoistway 102 side force can also perform the mounting work and the adjusting work. Therefore, after the assembly of the basket room 140 is completed and the elevator can be operated, the ceiling of the basket room 140 is used as a scaffold, and the smoke shield device 120 is also attached or adjusted on the hoistway 102 side. Can be done. Further, the smoke shielding device 120 can be replaced at the time of maintenance or the like.
- the three-sided frame installation process S5 and the header mounting process S6 and the sill mounting process S7 and the hold-aper installation process S8 and the smoke shielding device installation process S9 are performed in advance at the factory, and the three-way frame 105 and the sill 106 and the hold-ahead are mounted. It is also possible to bring it into the hoistway 102 and attach it in the state of a unit in which the 110 and the smoke shielding device 120 are combined. In this case, on-site work is only required to check and fine-tune the operation of the hold door 110 and to check the airtightness and fine-tuning of the smoke shield device 120! Is done.
- the assembling procedure shown in FIG. 27 shows an example of the assembling procedure of the elevator 101 with the smoke shield device.
- the attachment of the smoke shield device 120 is performed before the hold-a attaching process.
- the ceiling of the basket room 140 can be used as a scaffold to perform the installation work of the smoke shielding device 120.
- the airtightness between the elevator hall and the hoistway is improved with a simple configuration and without deteriorating the appearance, and the hoistway in the event of a fire in the elevator hall is improved.
- the chimney can be prevented from becoming a chimney and the development of fire can be suppressed.
- the disaster prevention device described above can be applied as a disaster prevention device for a sliding door that requires airtightness.
