Specifically, as shown in FIGS. 1 and 3, the first smoke shield 17 is a leaf spring 20 detachably fixed to the upper frame 10 of the three-way frame 8 by a known fixing means such as a screw. And a sliding member 21 attached to the free end of the leaf spring 20. When the two landing doors 7A and 7B are closed, the leaf spring 20 has a length that exceeds the entire length of the upper edge of the landing doors 7A and 7B. The sliding member 21 is in pressure contact. The sliding member 22 is also detachably supported on the upper edge portions of the landing doors 7A and 7B, to which the sliding member 21 is pressed, so as to be sandwiched between holders 23A and 23B such as spring materials.

  Furthermore, the sliding member 21 of the first smoke shield 17 is placed on the upper end of the door side of each landing door 7A, 7B via an L-shaped mounting bracket 24 as shown in FIGS. A closing member 25 serving as a door-side closing body having a vertical surface that slides and a horizontal plane continuous to the vertical surface is attached. The closing member 25 is attached to be adjustable in the vertical direction of the door and the thickness direction of the door. The closing member 25 supports a moquette sheet 26 from the surface facing the sliding member 21 to the lower surface.

As shown in FIGS. 4, 6 and 7, the second smoke shields 18 </ b> A and 18 </ b> B include the door side end of each landing door 7 </ b> A and 7 </ b> B and the door side end of the vertical frame 9 </ b> A (9 </ b> B) of the three-side frame 8. It is comprised by the 1st-3rd closing member 27-29 provided between these. The first closing member 27 is an L-shaped cross section that is fixed at the door pocket side ends of the landing doors 7A and 7B to the lower side of the closing member 25 with bolts or the like so as to be adjustable in the vertical direction along the height direction of the door. Formed. The second closing member 28 is supported by a bolt or the like so as to be adjustable in the door moving direction on the first closing member 27, and has an L-shaped cross section having a vertical surface protruding to the vertical frame 9A (9B) side of the three-side frame 8. I am doing. Here, the first closing member 27 and the second closing member 28 constitute a door side closing body. The third closing member 29 serving as the fixed-side closing body is supported by a bolt or the like on the door-side end of the vertical frame 9A (9B) of the three-sided frame 8, and is perpendicular to the vertical surface of the second closing member 28. It has an L-shaped cross section with a surface. Among them, the closing members 27 and 28 are configured so as to be in contact with the upper surface and the floor surface of the sill 11 at the lower ends, and therefore, the rubber plates 30A and 30B are interposed. Two closing members 27,
It projects downward from 28.

  On the other hand, the third smoke shields 19A and 19B are provided between the door shoes 15 (15A and 15B) and 16 (16A and 16B) and the door shoes 15A and 16A, as shown in FIGS. And the closing bodies 31A and 31B that block the space between the door shoes 15B and 16B. The door shoes 15A, 15B, 16A, 16B and the closing bodies 31A, 31B are formed of an elastic member and low friction sheets 32A, 32B provided on the surface thereof. The low friction sheets 32A and 32B are made of, for example, a polytetrafluoroethylene sheet, and the elastic member covers the surface in contact with the vertical wall of the sill groove 11G, thereby reducing friction with the sill groove 11G.

The door shoes 15 and 16 and the closing bodies 31A and 31B configured as described above are held on the vertical side of the L-shaped mounting bracket 33, and the horizontal side is supported by the lower ends of the landing doors 7A and 7B. The lower ends of the landing doors 7A and 7B have a horizontal side 7a bent at a right angle, and the horizontal side of the mounting bracket 33 is placed on the horizontal side 7a. Stud bolts 33a and 33b are erected on the horizontal side of the mounting bracket 33 with an interval in the door moving direction. Further, the fixing bracket 34 is fixed by fixing means such as a bolt B across the U-shaped bent portions on both sides in the width direction of the landing doors 7A and 7B. The fixing bracket 34 is also L-shaped, the vertical side is fixed to the door, and the horizontal side of the mounting bracket 33 is supported by the horizontal side. The fixing bracket 34 is also fixed to the horizontal side 7a at the lower end of the landing doors 7A and 7B. That is, the stud bolts 7b are erected at positions corresponding to both ends of the horizontal side 7a of the landing doors 7A and 7B in the door moving direction. A bolt hole 34b that penetrates the stud bolt 7b is provided in the fixing bracket 34, and the horizontal side of the fixing bracket 34 is fixed to the horizontal side 7a by fastening a nut (not shown).

Further, the horizontal side of the mounting bracket 33 is formed shorter than the interval between the stud bolts 7b, and the stud bolts 33a and 33b are erected there. In order to allow the stud bolts 33a and 33b to pass therethrough, a bolt hole 35a,
35b is provided. By attaching stud bolts 33a and 33b to these bolt holes 35a and 35b and fastening them with nuts N (FIG. 3), the mounting bracket 33 is fixed to the lower ends of the landing doors 7A and 7B.

  By the way, of the bolt holes 35a and 35b of the fixing bracket 34, one bolt hole 35b is an arc-shaped long hole centered on the other bolt hole 35a. By making the long holes in this way, even if the landing doors 7A and 7B are deformed and the door shoes 15A-16A and the door shoes 15B-16B and the sill groove 11G are not parallel, the bolt holes 35a are attached. The metal fitting 33 can be rotated and adjusted in parallel with the threshold groove 11G.

  According to the present embodiment, basically, when the entrance 4 is closed by the landing doors 7A and 7B, the gaps G1 and G2 generated between the three-way frame 8 and the sill 11 with respect to the landing doors 7A and 7B are the first. The smoke shield 17, the second smoke shields 18 </ b> A and 18 </ b> B, and the third smoke shields 19 </ b> A and 19 </ b> B can block the smoke flowing between the hoistway 2 and the landing 3 in the event of a fire. .

In addition, since the first to third smoke shields 17, 18A, 18B, 19A, 19B according to the present embodiment are detachably supported or fixed, respectively, with the landing doors 7A, 7B opened, Can be exchanged. That is, the leaf spring 20 provided with the sliding member 21 of the first smoke shield 17 can be removed by removing the screw, and can be replaced with a new leaf spring 20, which is on the side of the landing doors 7A and 7B. The sliding member 22 can also be replaced with a new sliding member 22 by being inserted and removed along the holders 23A and 23B. The second smoke shields 18A and 18B can also be replaced with new ones by removing the bolts of the first to third blocking members 27 to 29 which are constituent parts. Further, by loosening the bolt, the amount of protrusion of the second closing body 28 on the three-side frame 8 side and the door pocket side and the gap between the first and second closing bodies 27 and 28 and the sill 11 side are adjusted, The overlapping amount and contact pressure of the second and third closing bodies 28 and 29 and the contact pressure of the rubber plates 30A and 30B to the sill 11 and the floor can be adjusted. Also in the third smoke shields 19A and 19B, by removing or loosening bolts and nuts, the door shoe 15,
16 and the closing bodies 31A and 31B can be exchanged and the parallelism with the sill groove 11G can be adjusted.

By the way, the landing doors 7A and 7B according to the present embodiment are so-called two-door central opening landing doors that open and close the doorway 4 laterally from the center to both sides. Are provided with door stop rubbers 36A and 36B, respectively, so that the landing doors 7A and 7B directly abut against each other and the collision sound and the door are not damaged. By providing the door stop rubbers 36A and 36B, the door stop side of the opposite landing doors 7A and 7B is provided with a gap G3 as shown in FIGS. 7A and 7B are prevented from colliding. And in order to block this gap G3, the door shoe side guide shoes 15A, 15B are protruded from the door contact side of the landing doors 7A, 7B to a position approaching the tip end position of the door stop rubbers 36A, 36B.

  By forming the guide shoes 15A and 15B as described above, the space between the landing doors 7A and 7B and the sill 11 is closed. However, since the third smoke shields 19A and 19B including the guide shoes 15A and 15B are determined by the width of the threshold groove 11G, they must be formed smaller than the thickness of the landing doors 7A and 7B. As a result, from the gap formed between the door stop rubbers 36A and 36B and the guide shoes 15A and 15B, as shown in FIGS. May intrude and flow into the landing 3 side via the gap G3 on the door contact side of the landing doors 7A and 7B. Also, as shown in FIG. 12 (4), smoke may enter the gap G3 from the upper ends of the door stop rubbers 36A and 36B and flow into the landing 3 side.

In order to reduce such a slight flow of smoke, according to the present embodiment, the upper gap closing means 37A, which is a fourth smoke shield, is provided on the upper and lower sides of the landing doors 7A, 7B. The lower gap closing means 37B is provided. Each of the upper and lower gap closing means 37A and 37B includes closing bodies 38A and 38B that are in contact with each other so that no gap is formed between the one end and the door stop rubbers 36A and 36B. These closing bodies 38A, 38B are formed of the same material as the door stop rubbers 36A, 36B. The closing body 38A is on the door stop side of the landing door 7A, and the closing body 38B is on the door stop side of the landing door 7B. The doors are attached so as to be in contact with each other at the time of opening and closing the door. The projecting lengths (lengths in the door movement direction) of the closing bodies 38A and 38B are in contact with the door-stop side of the landing doors 7A and 7B facing the door-contact rubbers 36A and 36B when the door is closed. In order not to generate a gap between the rubbers 36A and 36B, the gap G3 is shorter than the door contact gap G3 of the landing doors 7A and 7B when the door is closed.

As described above, by providing the upper gap closing means 37A and the lower gap closing means 37B at the upper and lower portions of the landing doors 7A and 7B, the landing doors 7A and 7B at the upper and lower ends of the door stop rubbers 36A and 36B are provided. Smoke that tries to enter from the gap with the lower end enters the position shown by (1) in FIGS. 12 to 14 and the position shown by (4) in FIG. 13, but beyond that, it enters the door stop rubbers 36A and 36B. Since the blocking bodies 38A and 38B are in contact with each other, they do not flow into the landing 3 through the gap G3.

  By the way, the closing bodies 38A and 38B are made of the same material as the door stop rubbers 36A and 36B. However, the closing bodies 38A and 38B are softer and more compressible than the door stop rubbers 36A and 36B. In this case, it is possible to prevent the smoke from flowing by providing only one of the two blocking bodies 38A and 38B.

  That is, the length of the closing body is made longer than the gap G3 when the door is closed, and this is installed. By installing such a closing body, even when the door stop rubbers 36A and 36B come into contact with each other when the door is closed, the closing body is compressed and contracted in the gap G3. Therefore, the blocking body does not obstruct the contact of the door stop rubbers 36A and 36B, and the flow of smoke can be blocked.

  FIG. 16 is a second embodiment showing a structure for supporting the sliding member 22 shown in FIG. 3 on the upper edge portions of the landing doors 7A and 7B.

  That is, by increasing the vertical dimension of the sliding member 39 fixed to the landing doors 7A and 7B and sandwiching the sliding member 39 only by the lower portion with a holding tool 23A such as a spring material, the insertion / removal direction with respect to the holding tool 23A can be changed in the door moving direction and the upward direction. It is something that can be done. Other configurations are the same as those in the first embodiment.

FIG. 23 shows that the sliding member 22 provided on the upper edge of the landing doors 7A and 7B shown in FIG. 3 is always made of a material 55 that is harder than the sliding member 21 attached to the free end of the leaf spring 20. A configuration in which the sliding member 21 is worn is shown. With this configuration, the sliding members 55A and 55B attached to the landing doors 7A and 7B are not worn out, so that replacement is unnecessary. Further, in this configuration, as described above, the sliding member 55 attached to the landing doors 7A and 7B does not need to be replaced, so there is no need to make it a detachable configuration. It can be simplified and maintainability is improved.

  24 and FIG. 25, first to third doors provided between the door side end of the landing doors 7A and 7B shown in FIG. 6 and FIG. 7 and the door side end of the vertical frame 9A (9B) of the three-way frame 8 are shown. In the closing members 27 to 29, the closing members 27 and 28 are detachably attached to the sliding members 57 </ b> A and 57 </ b> B that come into contact with the upper surface and floor surface of the sill 11 at the lower ends by leaf springs 58 </ b> A to 58 </ b> F. According to this configuration, it is not necessary to project the rubber plates 30A and 30B downward from the closing members 27 and 28 as shown in FIG. For this reason, the rubber plate that closes the gap G1 with the vertical frame 9A only needs to be in the vicinity of the contact portion with the vertical frame 9A as indicated by 59A. In addition, as shown in FIG. 24, the closing member 29 of the vertical frame 9 can be made unnecessary by providing the folded portion 60 in the vertical frame 9. Further, as shown in the figure, the rubber plate is not necessarily provided on both the vertical frame 9 and the closing member 29, and the rubber plate 59 is similarly attached to either the folded portion 60 or the closing member 29 of the vertical frame. A smoke shielding effect is obtained.

  FIG. 17 is a third embodiment showing third smoke shields 19A and 19B that block the gap G2 between the lower edge portions of the landing doors 7A and 7B and the sill 11.

In this embodiment, the mounting bracket 40A is fixed to the lower edges of the landing doors 7A and 7B, and the mounting bracket 40B is supported so as to be adjustable in the vertical direction with respect to the mounting bracket 40A. The rubber plate 41 is fixed at a position opposite to the top surface of the 11 and the sliding material 42 is fixed to the surface of the rubber plate 41 facing the top surface of the sill 11 to constitute the third smoke shields 19A and 19B. It is. The mounting bracket 40B has a length that extends over the entire length of the door, and is configured to abut against each other on the door contact side of both landing doors 7A and 7B. Further, since the mounting bracket 40B is also provided with a smoke shielding function, a closing body 43 such as a moquette seat is attached to the mounting bracket 40B or the landing doors 7A and 7B so that no gap is formed between the mounting bracket 40B and the landing doors 7A and 7B. It is fixed.

  FIG. 18 and FIG. 19 show a fourth embodiment for preventing smoke from flowing from the upper and lower ends of the door stop rubbers 36A, 36B and a slight gap in the width direction of the landing doors 7A, 7B.

That is, by attaching the guide shoes 15A and 15B in contact with the door stop rubbers 36A and 36B provided on the landing doors 7A and 7B, between the lower ends of the door stop rubbers 36A and 36B and the width direction of the landing doors 7A and 7B. The guide shoes 15A and 15B and the third smoke shields 19A and 19B are slid in the sill groove 11G between the sill 11 and the lower ends of the landing doors 7A and 7B. Since it is blocked by this, the flow of smoke can be prevented.

  In the above embodiment, the upper edge portions of the landing doors 7A and 7B are opposed to the upper frame 10 of the three-way frame 8 which is a partition member that partitions the entrance / exit 4. However, depending on the design on the landing 3 side, the upper frame 10 of the three-way frame 8 does not exist, and instead a curtain is provided, and the door surfaces of the landing doors 7A and 7B are installed flush with the curtain. There is.

  FIG. 20 shows a fifth embodiment in which the door surfaces of the landing doors 7A and 7B are installed flush with the curtain plate.

That is, the landing doors 7A and 7B are arranged so that the door surface is flush with the curtain plate 44 provided in place of the upper frame of the three-way frame. Since the tops of these landing doors 7A and 7B are opposed to the curtain plate 44 through a minute gap, the hangers 12A and 12B cannot be hung there. Accordingly, a hanger bracket 45 having the same length as the door width is attached to the upper side surface of the landing doors 7A and 7B, and the hangers 12A and 12B are suspended from the hanger bracket 45. Then, the leaf spring 20 is detachably fixed by a known fixing means such as a screw at a position facing the hanger bracket 45 on the back side (the hoistway side) of the curtain plate 44, and the free end portion of the leaf spring 20 is fixed. The hanger bracket 45 is slidably pressed. Of course, the sliding member 21 is attached to the free end portion of the leaf spring 20 in order to make the sliding with the hanger bracket 45 smooth. Further, as shown in FIG. 3, the sliding member 22 is detachably supported at a position where the leaf spring 20 of the hanger bracket 45 is in sliding contact with the hanger bracket 45 so as to be sandwiched between holders 23A and 23B such as spring materials.

  Each of the above embodiments is a system in which the landing door is opened and closed on both sides from the center of the entrance / exit 4, but there is also a landing door in which the landing door is opened from one side to the other side.

  Hereinafter, as a sixth embodiment, a smoke shielding structure of a single-open landing door will be described with reference to FIGS. 21 and 22.

  21 and 22, the fundamentally different configuration from the first embodiment is that a plurality of landing doors 7A and 7B overlap adjacent edges when the door is closed. Since it is substantially the same, description is abbreviate | omitted.

  A fifth smoke shield 47 is provided on the door pocket side of the adjacent landing door 7A and the door stop side of the landing door 7B. The fifth smoke shield 47 includes first to third blocking members 48 to 50. The first closing member 48 has a length that extends over the entire height of the door, is supported by the door pocket side end of the landing door 7A, and is fixed with a bolt or the like so as to be adjustable in the vertical direction along the height direction of the door. It has an L-shaped cross section. The second closing member 49 also has a length extending over the entire height of the door, and is a cross section L having a vertical surface that is supported by the first closing member 48 with a bolt or the like so as to be adjustable in the door moving direction and protrudes toward the landing door 7B. It has a letter shape. The third closing member 50 has the same length as the first and second closing members 48 and 49, is supported by a door or the like on the door side of the landing door 7 </ b> B, and is perpendicular to the second closing member 49. It has an L-shaped cross section having a vertical surface facing the surface. The first to third closing members 48 to 50 are provided with rubber plates 51A to 51C in order to directly contact each other and prevent noise and vibration. Among these, the rubber plates 51A and 51B are downward from the lower ends of the first and second closing members 48 and 49 so that the lower ends thereof are in contact with the upper surface and floor surface (not shown) of the sill (not shown). Protruding.

  In the above configuration, when the door is opened, the door of the landing door 7B is such that the portion of the second closing member 49 supported by the landing door 7A that protrudes toward the landing door 7B does not contact the door side 7E of the landing door 7B. The folding dimension L2 on the side 7 is smaller than the folding dimension L1 on the door stop side. Further, on the door stop side of the landing door 8A, when the door is closed, the smoke-insulating rubber is provided over the entire height of the door so as to come into contact with the door stop rubber 55 attached over the entire height of the door stop-side vertical frame 53A of the three-way frame 52. 56 is attached. In addition, the smoke-insulating configuration of the door frame side vertical frame 53B or the upper frame 54 of the three-way frame 52 and each door is basically the same as that of the above embodiment.

  According to the present embodiment, in a single-opening landing door, as in the first embodiment, it is possible to prevent smoke from flowing between the hoistway and the landing during a fire, as well as construction and maintenance. Inspection can be performed easily.

  In addition, although description was abbreviate | omitted, it is equivalent by combining the structure by said each embodiment about the 1 door single opening landing door, the 3 door single opening landing door, the 4 door central opening landing door, etc. Needless to say, an effect can be obtained.
