The outdoor side holding plate 531 and the indoor side holding plate 532 are also integrated by riveting on the prospective surface of the vertical rod 53 in which the prospective surface portions 531A and 532A are overlapped.
Further, the end portions of the finding surface portions 531B and 532B are subjected to hemming bending, and the face material 50 is held between the finding surface portions 531B and 532B.
Further, a space corresponding to the plate thickness of the outdoor holding plate 531 formed by hemming bending is formed between the face material 50 and the finding surface portion 531B, and the adhesive 59 is applied to adhere the face material 50. Yes.

Further, the indoor holding plate 522 and the outdoor holding plate 531 are formed with smoke return portions 522C and 531C that protrude toward the other vertical wall.
The vertical rods 52 and 53 are formed by applying the adhesive 59 to the finding surface portions 521B and 531B of the outdoor holding plates 521 and 531 and bonding the face material 50, and then the outdoor holding plates 521 and 531 and the indoor holding plates. The 522 and 532 are assembled by riveting at the prospective surface of the vertical rods 52 and 53.

In FIG. 10, the vertical rods 54 and 55 of the butting portion of the external shoji 41 are shown.
The vertical rod 54 of the external obstacle 41 includes a fitting member 545 that forms a recess, and the other vertical rod 55 is fitted to the fitting member 545.
That is, as shown in FIG. 10, one vertical rod 54 in the butting portion has an outdoor holding plate 541, an indoor holding plate 542 that holds the face material 50 from the inside and outside, and an opening between the holding plates 541 and 542. It is comprised with the obstruction | occlusion board 543 which plugs up.

The outdoor side holding plate 541 is formed of a decorative steel plate having a thickness dimension of t0.5 and bent in a substantially U-shaped cross section. The indoor side holding plate 542 is made of a decorative steel plate having a thickness dimension of t0.5 and bent in a substantially L-shaped cross section. The closing plate 543 is made of a decorative steel plate having a thickness dimension of t0.5 and bent in a substantially U-shaped cross section.
The outdoor side holding plate 541 and the indoor side holding plate 542 include prospective surface portions 541A and 542A that are extended in the prospective direction of the vertical rod 54, and a finding surface portion 541B that is extended from the prospective surface portions 541A and 542A in the direction of finding the vertical rod 54. , 542B. The hemming processing of the finding surface portions 541B and 542B and the application of the adhesive 59 are the same as those of the vertical hooks 52 and 53, and thus description thereof is omitted. The closing plate 543 includes a prospective surface portion 543A.

The fitting member 545 includes a steel reinforcing member 546 having a U-shaped cross section and a decorative steel plate 547 that covers the outer surface of the reinforcing member 546.
The vertical rod 54 applies the adhesive 59 to the finding surface portion 541B of the outdoor side holding plate 541 to adhere the face material 50, and the outdoor side holding plate 541, the indoor side holding plate 542, the closing plate 543, and the fitting member 545 are attached. It is assembled by riveting at the prospective surface of the vertical rod 54.

  On the other hand, the other vertical rod 55 of the butt portion has the same configuration as the vertical rod 54 except that the fitting member 545 is not provided. That is, the vertical rod 55 includes an outdoor side holding plate 551, an indoor side holding plate 552, and a closing plate 553, sandwiching the face material 50 between the finding surface portions 551B and 552B, and being integrated by the prospective surface portions 551A, 552A, and 553A. This is the same as the downspout 54.

  In addition, since the downarm 51 of the inner shoji 42 is the same structure as the downarm 53, description is abbreviate | omitted.

When the external shovel 41 is closed and butted, the vertical rod 55 serving as a convex portion is inserted into the opening of the fitting member 545 serving as a concave portion. For this reason, as for the butting part of the external shoji 41, the space connected from the external side to the internal side of the external shoji 41 has a zigzag maze shape. For this reason, even if heat is applied to the external obstacle 41 due to a fire or the like, the vertical hook 55 does not come off the vertical pole 54, and a through hole is not generated between the external obstacles 41. For this reason, fireproof performance is securable.
In addition, the summing part of the shoji 41 and the inner shoji 42 is also provided with the smoke returning parts 522C and 531C of the vertical hooks 52 and 53. The portion 23 </ b> C becomes smoke return, and the space from the exterior side of the shoji 41, 42 to the interior side has a zigzag maze shape. For this reason, a through-hole does not generate | occur | produce also in these summoning parts, and fireproof performance is securable.

  It should be noted that a thermal expansion refractory material 60 is provided in each of the abutting portion between the two outer shojis 41, the summing portion of the outer shingles 41 and the inner shingles 42, and the engaging portion engaged with the vertical frame 23 of the inner shingles 42. Is affixed. The thermal expansion refractory material 60 is a refractory material that expands when heat is applied. In the event of a fire, the thermal expansion refractory material 60 expands, and the fire door 10 can ensure the necessary fire prevention performance by closing the gaps between the outer shoji 41 and the inner shoji 42. A part of the thermally expanded refractory material 60 is not shown in the explanation of other members.

[Sliding member]
Sliding members 70 that slide on the protrusions 314 and 324 of the rail members 31 and 32 are attached to the vertical rods 51 to 55 of the respective shojis 41 and 42. Therefore, in this embodiment, the sliding member 70 constitutes a moving member that moves in the groove of the lower frame 22 (in the concave groove portions 22A and 22B).
As shown in FIGS. 7 and 8, the sliding member 70 is made of a metal stopper 71 made of stainless steel or the like attached to the lower end of the prospective surface of each vertical rod 51 to 55, and on the lower surface of the stopper 71. The sliding part 72 is fixed.

The come-off prevention portion 71 is formed by bending a metal plate. The detachment preventing portion 71 includes a fixing portion 711, a face material support portion 712, a saddle material holding portion 713, and a locking portion 714.
The fixing portion 711 is screwed to the prospective surfaces of the vertical rods 51 to 55. The face material support part 712 extends in the horizontal direction from the lower end of the fixed part 711. The lower end surface of the face material 50 is placed on the face material support portion 712.

  The saddle material holding portion 713 is composed of a pair of projecting pieces provided to rise from an intermediate position in the extending direction of the face material support portion 712. The saddle material holding portion 713 prevents the finding surface portions 521B, 522B, 531B, 532B, 541B, 542B, 551B, and 552B from spreading by pressing each finding surface portion holding the face material 50 from the inside and outside of the room. . Further, since the saddle material holding portion 713 engages with the finding surface portion, the sliding member 70 screwed only by the fixing portion 711 is also prevented from rotating.

The locking portion 714 is formed so as to protrude from the distal end portion of the face material support portion 712 in the expected direction. The width dimension (expected dimension) of the locking portion 714 is larger than the opening width dimension between the protruding pieces 316 and 326 of the rail members 31 and 32. For this reason, even if the shojis 41 and 42 are lifted, the locking portions 714 are locked by the projecting pieces 316 and 326, so that the shojis 41 and 42 can be prevented from being detached from the lower rail members 31 and 32.
As described above, the projecting pieces 316 and 326 are formed with the notches 316A and 326A. For this reason, when the shojis 41 and 42 are attached to and detached from the lower frame 22, the shojis 41 and 42 may be moved up and down according to the positions of the locking portions 714A and 326A.

  The sliding portion 72 is screwed to the lower surface of the locking portion 714. The sliding part 72 is configured by a sheet having a small friction coefficient such as a fluororesin sheet. The sliding portion 72 has a width dimension larger than that of the locking portion 714 and protrudes from the end surface of the locking portion 714. For this reason, even when the lower ends of the shojis 41 and 42 are displaced to the indoor side or the outdoor side, the sliding portion 72 comes into contact with the rising portions 312, 313, 322, and 323, and the metal locking portion 714 comes into contact. Thus, the lower rail members 31 and 32 are prevented from being damaged.

The sliding member 70 is attached to the lower part of the vertical rods 51 to 55 of the shoji 41 and 42 and slides on the ridges 314 and 324. Thereby, the shoji 41 and 42 can move, without using a common door cart.
At this time, the lower ends of the shojis 41 and 42 are not provided with a lower collar, so that the lower ends of the face material 50 are exposed. The face material 50 is separated above the protrusions 314 and 324 by the thickness dimension of the face material support part 712 and the slide part 72 of the slide member 70, and obstructs the sliding movement of the shojis 41 and 42. Never do.
Moreover, as shown in FIG. 8, since the upper end part of the shoji 41 is not provided with the upper collar, the upper end part of the face material 50 is exposed. The upper end portion of the face material 50 is clamped by the mohair 38 of the rail members 36 and 37 together with the upper end portions of the vertical rods 51 to 55, and the upper end portions of the shojis 41 and 42 are guided by the mohair 38 and slid.

As shown in FIG. 9, a substantially Z-shaped engaging member 66 is screwed to a substantially central portion in the height direction of the vertical hook 52 of the inner shroud 42.
Moreover, although not shown in figure, you may enable it to attach and lock each vertical hook 54,55 of the butt | matching part of the external shoji 41 by attaching a lock and a lock receptacle.

[Opening and closing the fire door]
When the external shoji 41 is opened, only the external shoji 41 is moved at first, and when the external shoji 41 comes into contact with the engaging member 66, the inner shoji 42 is also moved in conjunction with the movement of the external shoji 41. Then, when the engaging member 66 comes into contact with the vertical frame 23, the outer obstacle 41 and the inner obstacle 42 are stopped. This stop position is the fully open position of the shojis 41 and 42. At this time, the outer shoji 41 and the inner shoji 42 are arranged to overlap in the inner and outer directions. The fully open position is a position at which most of the glass portion of the window 2 is exposed, so that the view from the room is not obstructed.
On the other hand, when the external shoji 41 is closed from the fully open position, only the external shoji 41 is moved at first, and the vertical hook 53 of the summing part of the external shoji 41 is engaged with the vertical hook 52 of the summing part of the inner hand child 42. In conjunction with the movement of the external shoji 41, the inner shoji 42 also moves. Then, when the vertical rod 51 on the door-end side of the inner limb 42 abuts on the vertical frame 23, the outer limb 41 and the inner limb 42 are stopped. This stop position is the fully closed position of the shojis 41 and 42.

According to this embodiment, the following effects can be obtained.
The shojis 41 and 42 are composed of a glass face material 50, vertical gutters 51 to 55 attached to the left and right ends of the face material 50, and a sliding member 70 attached to the lower ends of the vertical gutters 51 to 55. There is no upper arm or lower arm. For this reason, since there is no portion hidden by the upper and lower eyelids, the area of the finding surface of the face material 50 can be increased, and the lighting performance can be improved.
In addition, when the upper and lower eyelids are provided, the upper and lower eyelids are exposed along the upper frame 21 and the lower frame 22, but in this embodiment, as shown in FIGS. , 42 are encased in the grooves of the upper frame 21 and the lower frame 22, so that the design of the upper and lower frame parts becomes simple and the design of the fire door 10 can be improved. In particular, in the present embodiment, the shojis 41 and 42 are slim shojis whose height is larger than the width of the finding surface, so that only the long face material 50 and the vertical rods 51 to 55 are exposed in the vertical direction. The design property can be improved.

Moreover, since the sliding member 70 is attached to the lower end part of the said vertical shaft 51-55, and this sliding member 70 is slid on the rail members 36 and 37, a structure is compared with the case where a doorwheel is provided. It can be simplified and the cost can be reduced.
Furthermore, compared with the case where a doorwheel is provided at the lower end of the vertical fences 51 to 55, the found dimensions and the expected dimensions of the vertical fences 51 to 55 can be reduced, and a slim design can be achieved. From this point, it is possible to improve daylighting and design.

Further, since the locking member 714 is formed on the sliding member 70 and the projecting pieces 316 and 326 are formed on the rail members 36 and 37 of the lower frame 22, when the shoji 41 and 42 are opened and closed, one vertical rod side is When the shoji 41 and 42 are lifted due to a storm or the like, the locking portion 714 comes into contact with the protruding pieces 316 and 326, so that the shoji 41 and 42 are detached from the lower frame 22 and fall off. Can be prevented.
Furthermore, since the latching | locking part 714 is formed in the sliding member 70, compared with the case where it forms in the vertical hooks 51-55, the process and assembly of the vertical hooks 51-55 become easy, and production efficiency can also be improved. .

The vertical rods 51 to 55 include outdoor side holding plates 521, 531, 541, and 551 and indoor side holding plates 522, 532, 542, and 552 formed by bending a metal plate material. For this reason, compared to the case where a vertical plate is constituted by a single plate material, the bending process is simplified, and the adhesive 59 for fixing the face material 50 can be uniformly applied, so that the face material 50 can be securely attached. Can be glued to.
Further, the outdoor side holding plates 521, 531, 541, and 551 and the indoor side holding plates 522, 532, 542, and 552 are integrated by connecting each prospective surface portion with a rivet or the like, and thus are required as the vertical rods 51 to 55. Since it is not necessary to use an aggregate separately, the number of members can be reduced and the cost can be reduced.

Moreover, in the vertical rods 51-55, the edge part of the part holding the face material 50 is comprised by hemming bending process. For this reason, the designability of the parting part of the face material 50 and the vertical hooks 51-55 can be improved. Moreover, a contact with the glass face material 50 can be made smooth, and it can prevent that the edge of the vertical hooks 51-55 hits glass and it breaks.
Furthermore, the gap formed by the hemming bending process can be used as a joint where the adhesive 59 is applied, and the adhesive 59 can be prevented from protruding beyond the hemming bending process part.
Further, since the adhesive 59 is provided only on the outdoor side of the face material 50, when the adhesive 59 is ignited by an external flame, the flame of the adhesive 59 can be prevented from blowing into the indoor side.

Since the outer rail member 31 is placed on the upper surface of the adjustment screw 33, it can be adjusted to an appropriate height by adjusting the height position of the adjustment screw 33. At this time, since the adjustment screw 33 is arranged in accordance with the position of the adjustment hole 315, the height position of the adjustment screw 33 can be adjusted by operating from the adjustment hole 315 using a screwdriver. For this reason, the adjustment work of the height position of the outer rail member 31 can be performed without removing the external shoji 41. Therefore, even if the shoji is poorly installed, it can be easily adjusted without removing the shoji and the maintainability can be improved.
Moreover, since the adjustment screw 33 is provided on each of the inner side and the outer side of the ridge portion 314, the inclination of the outer rail member 31 can be adjusted. For this reason, the shoji 41 can be correctly stood on the outer rail member 31.
Furthermore, since the adjustment screw 33 is provided in the butting part of the outer obstacle 41, it can be corrected that the outer obstacles 41 to be opposed to each other are inclined in the finding direction or in the prospective direction. For this reason, it can prevent that a clearance gap arises in the butt | matching part of the external shoji 41, and can prevent that watertight performance and fireproof performance fall.

Since the adjustment hole 315 serves not only for adjusting the height position of the adjustment screw 33 but also as a drainage hole, the water that has entered the outer rail member 31 can be discharged from the adjustment hole 315 to the concave groove portion 22A and from the concave groove portion 22A. It can drain to the outside of the lower frame 22. For this reason, the problem that water accumulates in the screw hole and cannot be drained can be prevented.
Further, since the rising portions 312 and 313 of the outer rail member 31 protrude downward from the horizontal surface portion 311, even when the adjustment screw 33 is adjusted to the lowest position, a gap is formed between the horizontal surface portion 311 and the bottom surface portion 222D. It can be ensured, and the drainage performance can be prevented from deteriorating.
In addition, since the rail members 31 and 32 are placed on the adjustment screw 33, the adjustment screw 33 does not protrude from the upper surface of the rail members 31 and 32. Further, the countersunk screw 35 that fixes the rail members 31 and 32 to the lower frame main body 220 does not protrude from the upper surface. For this reason, it can prevent that the adjustment screw 33 and the countersunk screw 35 inhibit the movement of the shoji 41, and can move the shoji 41 smoothly.

Since the adjustment member is constituted by the adjustment screw 33 and the adjustment hole 315 is constituted by a long hole, a gap for drainage can be reliably formed between the screw head and the adjustment hole 315. In the present embodiment, since the head of the adjustment screw 33 is spherical, if the longitudinal dimension of the adjustment hole 315 is larger than the width dimension, the adjustment screw is placed on both ends of the adjustment hole 315 in the longitudinal direction. 33 can be formed. In particular, if the length of the adjustment hole 315 is equal to or greater than the diameter of the head of the adjustment screw 33, a drainage gap can be reliably formed between the screw head and the adjustment hole 315. For this reason, the structure for using the adjustment hole 315 also as a drainage hole can be simplified, and the cost can be reduced.
Further, since the height can be adjusted simply by turning the adjusting screw 33 with a screwdriver, the configuration of the adjusting member can be simplified and the cost can be further reduced. In addition, since the height of the adjustment screw 33 can be finely adjusted by the number of rotations by the driver, the height position of the outer rail member 31 can be finely adjusted, and the adjustment workability can be improved.

  Since the lower frame main body 220 is made of a steel material, even if the aluminum rail members 31 and 32 are damaged by a fire, the lower frame main body 220 whose melting temperature is higher than that of the rail members 31 and 32 is the shoji 41 and 42. Can be supported. For this reason, it can prevent that the shoji 41 and 42 fall out at the time of a fire.

Further, since the rail members 31, 32 and the rail members 36, 37 are made of an aluminum material, the rail members 31, 32, 36, 37 having protrusions 314, 324 and the like having a complicated sectional shape are made of steel material. Compared with the case where it comprises, it can manufacture easily.
Furthermore, since the rail members 31, 32, 36, and 37 are formed in a U-shaped cross section, the rigidity of the long rail members 31, 32, 36, and 37 can be secured, and the rails are not distorted or bent. Can do. Furthermore, since the rail members 31, 32, 36, and 37 can be brought into contact with the indoor side wall portions and the outdoor side wall portions of the concave groove portions 21A, 21B, 22A, and 22B, the rail members 31, 32 with respect to the inside of the concave groove portions 22A and 22B. , 36, 37 can be easily positioned.

  Since the thermal expansion refractory material 60 is provided at the engaging portion of the upper frame 21, the lower frame 22, the vertical frame 23, and the shoji 41, 42 of the joinery frame 20, the fire prevention line can be reliably configured, and the fire door 10 is sufficient. Fireproof performance can be secured. In particular, since the butt portion of the outer cover 41 has a concave-convex fitting structure by the vertical rods 54 and 55, no gap is generated in the butt portion even if the outer cover 41 warps during a fire, and fire resistance can be ensured.

Since the front bracket 26 is attached to the outer wall 1, the opening 226 of the lower frame 22 can be inserted and supported. For this reason, the joinery frame 20 can be temporarily placed on the outer wall 1, and the attachment workability of the joinery frame 20 can be improved.
Further, since the front bracket 26 is accommodated in the lower frame 22, it is not exposed to the outside and the design can be improved.
Furthermore, since the leading bracket 26 is housed in the lower frame 22, the strength of the lower frame 22 can be improved. In particular, since part of the weight of the shojis 41 and 42 can be supported by the front bracket 26, the lower frame 22 does not hang down due to the load of the shojis 41 and 42, and the support strength of the shojis 41 and 42 can be improved.

In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.
For example, in the above-described embodiment, the fire door 10 is configured by four shoji 41 and 42, but as shown in FIG. Good. That is, when the opening size of the window 2 is small, the fire door 10 </ b> A having only the two outer screen elements 41 may be provided. In this case, the upper frame 21 and the lower frame 22 may be provided with one concave groove 21A, 22A. For this reason, what is necessary is just to design the shape of the steel plate 212 and the steel plate 222 so that one concave groove part 21A, 22A may be formed. Further, when the opening size of the window 2 is large, five or more shoji screens may be provided.

In the above embodiment, the height adjustment mechanism including the adjustment hole 315 and the adjustment screw 33 is provided only in the abutting portion of the outer screen 41, but a plurality of adjustment holes 315 are formed in the outer rail member 31 at a predetermined interval, A plurality of adjustment screws 33 may be provided on the frame main body 220 side in correspondence with the adjustment holes 315. In this case, the overall height position of the outer rail member 31 can be freely adjusted.
Moreover, in the said embodiment, although the height adjustment mechanism was provided only in the external obstacle 41, you may provide also in the internal obstacle 42. FIG. In particular, if a height adjustment mechanism is provided in the summing part of the inner shoji 42, the outer shoji 41, and the vertical frame 23, the distance between the shojis and the vertical frame in the summing part can be made constant. Can be installed in the correct orientation. However, since the shoji 41 and 42 and the vertical frame 23 overlap in the prospective direction in the summoning section, there is no possibility that a gap that affects the fire resistance is generated even if the shoji 41 and 42 are slightly inclined in the summoning section. . Therefore, a height adjustment mechanism may be provided at least at the butting portion of the external shoji 41 as in the above embodiment.

  Moreover, although the upper frame main body 210, the lower frame main body 220, and the rail members 31, 32, 36, and 37 are made of different materials of steel and aluminum, they may be made of steel. And you may comprise with an aluminum material. For example, in the case of a joinery that does not require fire resistance, the upper frame body 210, the lower frame body 220, and the rail members 31, 32, 36, and 37 may be made of aluminum.

The adjustment member that adjusts the height of the rail members 31 and 32 is not limited to the adjustment screw 33 as long as the height can be adjusted by an operation from the adjustment hole 315. Further, the adjusting screw 33 is not limited to the bind screw used in the above embodiment, and may be a flat head screw or the like as long as the rail members 31 and 32 can be placed and the height thereof can be adjusted.
In the above-described embodiment, the front bracket 26 is provided at a position for supporting the lower frame 22, but may be provided at a position for supporting the upper frame 21 by being inserted into the opening of the upper frame 21. Also in this case, the joinery frame 20 can be temporarily fixed by the leading bracket 26, workability can be improved, and the support strength of the fire door 10 can be improved.
Further, both the upper frame 21 and the lower frame 22 may be supported by the tip bracket 26. In this case, the support strength of the fire door 10 can be further improved.

As a moving member attached to the lower end part of the said vertical shaft 51-55, the doorwheel which moves on the said protrusion (rail) 314,324 may be sufficient. If a door cart is used, the sliding movement of the shoji 41 and 42 can be performed more smoothly than the case where the sliding member 70 is used as a moving member.
Moreover, since the protrusions 314 and 324 of the rail members 31 and 32 of the present embodiment can also be used as a rail for a doorcar, it is not necessary to prepare a rail member for the doorcar separately, and the cost can be reduced.

When the sliding member 70 is used as the moving member, the protrusions 314 and 324 of the rail members 31 and 32 are not limited to those that can also be used as the rails of the door wheel. That is, the protrusions 314 and 324 of the above embodiment have a small width so that they can also serve as rails for the door roller, and the width of the sliding surface that contacts the sliding member 70 on the top surface of the protrusions 314 and 324 The dimensions were also small. On the other hand, the width dimension of the ridge portion may be increased to increase the width dimension of the sliding surface as compared with the above embodiment. In this case, the area which contacts the sliding member 70 becomes wide, and the sliding member 70 can be guided more stably. Moreover, as a protrusion part, you may have a cross-sectional shape which protruded in the circular arc shape from the horizontal surface parts 311 and 321. FIG.
Further, the rail members 31 and 32 do not have protrusions protruding from the horizontal surface portions 311 and 321, but the surfaces of the horizontal surface portions 311 and 321 are formed flat to be sliding surfaces. A protruding portion that protrudes downward may be formed on the sliding portion 72 and may be brought into contact with the sliding surface.

  The joinery of the present invention is not limited to the fire door 10. For example, it may be used as a shutter or shutter that does not have fireproof performance. Furthermore, you may utilize as a window provided in the opening part of a building, not only what is mounted | worn outside the window 2 of a building. That is, the present invention may be applied to sliding windows and sliding doors.

In addition, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this. That is, the invention has been illustrated and described with particular reference to certain specific embodiments, but without departing from the spirit and scope of the invention, Various modifications can be made by those skilled in the art in terms of material, quantity, and other detailed configurations.
