JP 7-173965 A

However, in patent document 1, when rainwater etc. enter into the upper surface of the sliding door receiving material in which the rail was formed, there is no structure which drains the water. In particular, since the height adjusting screw is buried in the screw hole, water is accumulated in the screw hole portion, and this water cannot be drained.
Moreover, in patent document 1, when the height of a sliding door receiving material is made low, there exists a problem that the head of a height adjustment screw protrudes from the upper surface of a sliding door receiving material. If the height adjusting screw protrudes, it interferes with the door roller and obstructs the movement of the shoji, or damages the door wheel.

  An object of the present invention is to provide a lower frame and a fitting that can easily adjust the height of the rail, can easily drain water that has entered the rail, and the adjustment member does not protrude on the rail.

The lower frame of the present invention is a lower frame that includes a lower frame main body and a rail member to guide a shoji, and the lower frame main body includes a recessed groove portion in which the rail member is disposed, and the rail member includes a plate A horizontal horizontal surface portion, a protrusion extending along the longitudinal direction of the rail member and formed on the upper surface of the horizontal surface portion so as to be able to guide the shoji, and an adjustment hole formed in the horizontal surface portion. , the adjusting holes are formed respectively on the outer and inner side of the protruding portion, the concave groove portion of the front Symbol lower frame body, adjusting member is aligned with the position of each adjusting hole, of the rail member The horizontal plane portion is placed on the upper surface of the adjustment member, and the adjustment member is configured to be capable of adjusting the height position and inclination of the rail member with respect to the lower frame body by operation from the adjustment hole, The adjustment hole is a drain hole for draining water on the rail member. Characterized in that it also serves.

According to the present invention described above, the rail member is disposed in the recessed groove portion of the lower frame main body, and is placed on the upper surface of the adjustment member. For this reason, since the rail member is only guided by the concave groove portion and is not fixed by a screw or the like, it can be easily detached or attached from the lower frame main body by removing the shoji. For this reason, according to the kind of shoji, etc., when the rail has to be replaced or when the rail is replaced with a new rail due to damage, the rail member can be easily replaced.
Moreover, since the rail member is mounted on the upper surface of the adjustment member, it can be adjusted to an appropriate height by adjusting the height position of the adjustment member. In particular, in the present invention, the adjustment member is arranged in accordance with the position of the adjustment hole, and the height position of the adjustment member can be adjusted by operating the adjustment hole using, for example, a screwdriver. Can be adjusted easily. In addition, since the adjustment members are respectively provided on the inner side and the outer side of the protruding portion, the inclination of the rail member can be adjusted. For this reason, the shoji can be arranged on the rail member in the correct orientation. Note that the outside of the protrusion means the outside of the shoji, that is, the outside when the shoji divides the inside and outside of the room, and the inside means the inside of the shoji, that is, the inside of the room.
Furthermore, since the height position adjustment of the adjustment member can be executed by an operation from the adjustment hole, the adjustment operation of the height position of the rail member can be performed without removing the shoji. For this reason, even if the shoji is poorly built, it can be easily adjusted without removing the shoji.
In addition, in the present invention, the adjustment hole serves not only for adjusting the height position of the adjustment member but also as a drainage hole, so that water that has entered the rail member is discharged from the adjustment hole to the concave groove portion of the lower frame body. it can. In the lower frame main body, for example, drainage holes can be formed at both ends in the longitudinal direction of the rail member, thereby draining the exterior of the joinery. For this reason, the problem that water accumulates in the screw hole and cannot be discharged can be prevented.
Further, since the rail member is placed on the adjustment member, the adjustment member does not protrude from the upper surface of the rail member. For this reason, it can prevent that an adjustment member inhibits the movement of a shoji, and can move a shoji always smoothly.

  At this time, in the lower frame of the present invention, the recessed groove portion of the lower frame main body includes a bottom surface portion, an outdoor side wall portion formed on the outdoor side of the bottom surface portion, and an indoor side wall portion formed on the indoor side of the bottom surface portion. The adjustment member is formed of an adjustment screw screwed into the bottom surface portion, and the adjustment hole has a width dimension smaller than the diameter of the head of the adjustment screw and has a length. It is preferable that the dimension is constituted by a long hole larger than the width dimension, and the groove at the head of the adjustment screw is exposed to the adjustment hole.

If the adjustment member is made up of an adjustment screw screwed into the bottom of the lower frame body, the height of the adjustment screw can be easily adjusted simply by inserting a screwdriver into the cross groove formed on the head of the adjustment screw and turning it. Can be adjusted. Further, if the adjustment member is configured with an adjustment screw, the configuration of the adjustment member can be simplified and the cost can be reduced.
Furthermore, if the adjustment hole is constituted by a long hole, a gap can be formed between the screw head and the adjustment hole only by making the length of the long hole equal to or larger than the diameter of the head of the adjustment screw, for example. For this reason, the configuration for using the adjustment hole as a drainage hole can be simplified, and the cost can be reduced.

Further, in the lower frame of the present invention, the lower frame main body and the rail member are made of different materials, and the lower frame main body is made of a member having a higher melting temperature than the rail member. preferable.
For example, the lower frame body may be made of a steel material and the rail member may be made of an aluminum material. If comprised in this way, even if an aluminum rail member is damaged by a fire, since the lower frame main body whose melting temperature is higher than a rail member remains, a shoji is supported by the ditch | groove part of a lower frame main body. For this reason, it can prevent that a shoji falls out at the time of a fire.
On the other hand, if the rail member is made of an aluminum material or the like, the rail member having a complicated cross-sectional shape can be easily manufactured as compared with the case of being made of a steel material.

Further, the lower frame of the present invention, the rail member includes at least a rising portion which rises upward from the outdoor side or one edge of the interior side of the horizontal portion, the ridge portion on the upper surface of the horizontal portion Preferably it is formed.
If the rail member includes a plate-shaped horizontal surface portion and a rising portion, the rail member can be formed in a substantially L-shaped cross section. For this reason, the rigidity of a rail member can be improved compared with the case where a rail member is comprised only in a horizontal surface part.
In addition, as a rail member, you may form a standing part from each indoor and outdoor edge of a horizontal surface part, and may form it in cross-sectional substantially U shape. Furthermore, the lower end side of the rising portion may be protruded downward from the horizontal plane portion.

The joinery of the present invention includes a joinery frame configured by the lower frame, the upper frame, and the left and right vertical frames, and a pair of butt screens that are opened and closed by moving along the upper and lower frames of the joinery frame. The adjustment hole is provided with at least four adjustment holes according to the butting portion when the shoji is closed, and the at least four adjustment holes are respectively formed on the outer side and the inner side of the convex upper part. And is formed at positions separated from the butting position when the shoji is closed to one side and the other side in the longitudinal direction of the rail member, and the adjusting member is aligned with the position of the adjusting hole. It is preferable that at least four are provided at the abutting portion when the is closed.
According to the present invention, since the adjusting member is provided at least in the butt portion of the shoji, the shojis faced with each other are inclined in the moving direction (finding direction) of the shoji, or the indoor / outdoor direction of the shoji (prospective direction). You can fix it. For this reason, it can prevent that a clearance gap arises in the butt | matching part of a shoji, and can prevent that watertight performance and fireproof performance fall.

In the joinery of the present invention, a concave portion is formed in the butt portion of the one butt shoji, a convex portion is formed in the butt portion of the other butt shoji, and a convex portion is formed in the concave portion when the shoji is closed. It is preferably inserted.
According to the present invention, since the butt portion of the shoji has a concavo-convex fitting structure, no gap is generated in the butt portion even if the shoji warps during a fire, and fire resistance can be ensured.

In the joinery of the present invention, the shoji is composed of an outer panel and an inner panel, each panel is composed of a steel plate, the thickness dimension of the inner panel is larger than the thickness dimension of the outer panel, Both end edges in the width direction are bent in a U-shape, and include a vertical hook portion orthogonal to the inner panel surface and a panel receiving portion orthogonal to the vertical hook portion, and the outer panel includes an inner panel It is preferable to be fixed to the panel receiving part.
According to the present invention, since the thickness dimension of the inner panel is made larger than that of the outer panel, the rigidity required for the shoji can be obtained only by the inner panel. For this reason, it is not necessary to provide a vertical bone separately and fix to a panel, and manufacture of a shoji becomes easy.
In addition, the inner panel only needs to be bent at both end edges in a U-shape and can be easily manufactured. Furthermore, since the panel receiving part which fixes an outer panel to an inner panel is comprised integrally, an inner panel and an outer panel can also be fixed easily.
In addition, since the outer panel has a smaller thickness than the inner panel, a groove or the like for improving the design can be easily processed. For this reason, it can be set as the shoji with the high design of an external appearance.

In the joinery of the present invention, the lower frame includes an opening that is opened on a wall side of a building to which the joinery is attached, and the wall of the building can be inserted into the opening of the lower frame to support the lower frame. The tip bracket is preferably fixed.
According to the present invention, since the opening of the lower frame can be inserted into and supported by the bracket attached to the wall of the building, the joinery frame can be temporarily fixed to the wall. For this reason, attachment workability | operativity can be improved at the time of the operation | work which fixes a joinery frame to a wall with a fixing screw. Furthermore, the strength of the lower frame can be improved because the leading bracket is housed in the lower frame. In particular, since a part of the weight of the shoji can be supported by the front bracket, the lower frame does not hang down due to the load of the shoji, and the support strength of the shoji can be improved.

Rail members 31 and 32 for guiding the shojis 41 and 42 are disposed in the concave grooves 22A and 22B.
The rail member 31 is an outer rail member that guides the shoji 41, and the rail member 32 is an inner rail member that guides the inner shroud 42.
The outer rail member 31 is disposed in the recessed groove portion 22A. The outer rail member 31 is an aluminum shape having a substantially U-shaped cross section, a horizontal surface portion 311 facing the bottom surface portion 222D, a first rising portion 312 continuous from the outdoor edge of the horizontal surface portion 311 and a horizontal surface portion. And a second rising portion 313 continuous with the indoor side edge of 311.
A protrusion 314 is formed on the upper surface of the horizontal surface portion 311. The ridge portion 314 is a rail that guides a door wheel or the like of the external shoji 41.

As shown in FIGS. 7 and 8, adjustment holes 315 are respectively formed at predetermined positions of the horizontal surface portion 311 of the outer rail member 31 on the outer side and the inner side of the ridge portion 314 (the outer side and the inner side of the shoji 41). Yes. In the present embodiment, at least 60 mm is formed in the left-right direction (longitudinal direction of the outer rail member 31) from the abutting position when the external obstacle 41 is closed. That is, at least four adjustment holes 315 are formed in accordance with the abutting portion of the external obstacle 41.
As shown in FIG. 9, the adjustment hole 315 is a long hole extending in the longitudinal direction of the outer rail member 31, and is formed through the horizontal plane portion 311.

An adjustment screw 33 that is an adjustment member is provided in accordance with the position of the adjustment hole 315. The adjustment screw 33 is a general screw in which the surface of the head is curved into a spherical shape to form a cross groove.
The diameter of the head of the adjusting screw 33 is set to be smaller than the dimension in the longitudinal direction of the adjusting hole 315 and larger than the width dimension orthogonal to the longitudinal direction. Therefore, the head of the adjustment screw 33 engages with the adjustment hole 315 at the top side where the cross hole is formed, and a gap is formed between the adjustment screw 33 and the adjustment screw 33 at both ends in the longitudinal direction of the adjustment hole 315. Has been. For this reason, when water enters the adjustment hole 315, the water flows on the bottom surface portion 222D of the concave groove portion 22A through the gap. At both ends in the longitudinal direction (finding direction) of the concave groove portion 22A, there are drain holes (not shown) for draining the water in the concave groove portion 22A to the outside of the lower frame 22, and flowed into the concave groove portion 22A from the adjustment hole 315. Water is drained from the drain hole to the outside of the lower frame 22.
Note that a V-groove that communicates with the adjustment hole 315 is formed in the horizontal plane portion 311, so that water that has entered the horizontal plane portion 311 can flow smoothly into the adjustment hole 315.

The adjustment screw 33 passes through the bottom surface portion 222D and is screwed into a back plate 34 attached to the back surface of the bottom surface portion 222D. The back plate 34 is fixed to the bottom surface portion 222D with fixing screws 341.
The cross groove of the adjustment screw 33 is exposed in the adjustment hole 315. Therefore, the height position of the adjustment screw 33 can be adjusted by turning it with a screwdriver 35 as shown in FIG. By adjusting the height position of the adjustment screw 33, the height position of the outer rail member 31 placed on the adjustment screw 33 can also be adjusted. That is, by adjusting the height of each adjustment screw 33 inside and outside the room, the inclination of the outer rail member 31 in the indoor / outdoor direction can be adjusted. Moreover, the inclination of the outer rail member 31 in the longitudinal direction can be adjusted by adjusting the height of each adjustment screw 33 provided across the butted portion of the outer panel 41. As a result, as will be described later, it is possible to correctly stand the external obstacle 41, and to prevent a gap from being generated at the butt portion of the external obstacle 41.

  The rising portions 312 and 313 of the outer rail member 31 also extend downward from the horizontal surface portion 311. When the outer rail member 31 is placed on the bottom surface portion 222D, the distance between the horizontal surface portion 311 and the bottom surface portion 222D is increased. A gap having a predetermined dimension is formed on the surface. The heads of the adjusting screws 33 and the fixing screws 341 are arranged in the gaps. For this reason, even when the adjustment screw 33 is set to the lowest position, a gap is formed between the horizontal surface portion 311 and the bottom surface portion 222D.

The inner rail member 32 is disposed in the recessed groove portion 22B. The inner rail member 32 is an aluminum profile having a substantially U-shaped cross section, and includes a horizontal plane part 321 that faces the bottom surface part 222D, a first rising part 322 that continues from the outdoor edge of the horizontal plane part 321, and a horizontal plane part. 321 is provided with a second rising portion 323 continuous with the indoor side edge of 321.
A protrusion 324 is formed on the upper surface of the horizontal surface portion 321. The ridge portion 324 is a rail that guides a door wheel or the like of the inner shoji 42.
The rising portion 322 is disposed along the angle member 28. A cover portion 325 is formed at the upper end of the rising portion 322 so as to extend to the outdoor side and come into contact with the outer rail member 31.

[Composition of upper frame]
As shown in FIG. 3, the upper frame 21 is composed of two steel plates 211 and 212. The steel plates 211 and 212 are steel plates having a thickness dimension of t0.8 to t1.5, and satisfy the structural regulations required for fire prevention equipment.
The steel plate 211 constitutes an upper surface of the upper frame 21 and a concave groove portion 21 </ b> A for guiding the upper end portion of the external obstacle 41 between the steel plate 212.
The steel plate 212 constitutes the lower surface of the upper frame 21 and the concave groove portion 21 </ b> B that is bent into a concave groove shape and guides the upper end portion of the inner limb 42.
These steel plates 211 and 212 overlap each other at the concave groove portion 21B, and are fixed to each other using a fixing screw at this portion.

As shown in FIG. 5, an end cap 25 similar to the lower frame 22 is attached to the end face in the longitudinal direction of the upper frame 21, and the steel plates 211 and 212 are also connected by this end cap 25.
Further, as shown in FIG. 3, the upper frame 21 is fixed to the outer wall 1 by screwing fixing screws 27 through long holes 217 formed in the steel plate 211 at predetermined intervals. The head of the fixing screw 27 is covered with a cover material 271.

[Configuration of vertical frame]
As shown in FIGS. 4 and 5, the vertical frame 23 is made of a steel material having a substantially U-shaped cross section. The vertical frame 23 is a steel plate having a thickness dimension of t0.8 to t1.5, and satisfies the structural regulations required for fire prevention equipment.
The vertical frame 23 includes a fixing portion 23A that is fixed to the outer wall 1, a vertical frame main body portion 23B that is bent in an orthogonal direction from the fixing portion 23A and extends in a prospective direction, and an outdoor end portion of the vertical frame main body portion 23B. And a bent engagement portion 23C.
The finding dimension of the fixing portion 23A is longer than that of the engaging portion 23C, and the vertical frame 23 is fixed to the outer wall 1 by screwing the fixing screw 27 from the fixing portion 23A.

[Configuration of shoji]
Next, the configuration of the shoji will be described. The shoji is a four-story shoji consisting of two external shoji 41 and two inner shoji 42.
As shown in FIGS. 10 and 11, each of the shojis 41 and 42 includes a steel (steel plate) outer panel 43 and an inner panel 44. The thickness dimension of the inner panel 44 is set to a thickness dimension that satisfies the structural regulations as a fire prevention equipment. On the other hand, the thickness dimension of the outer panel 43 does not need to satisfy the structure regulations, and is therefore a thickness dimension that emphasizes workability and design. For this reason, the thickness dimension of the inner panel 44 is made larger than the thickness dimension of the outer panel 43. For example, the thickness dimension of the inner panel 44 is set in the range of t0.8 to t1.5 in the structural regulations as fire prevention equipment. For example, in this embodiment, the thickness dimension is 1.0 mm. On the other hand, the thickness dimension of the outer panel 43 is 0.4 mm.
Both end edges in the width direction of the inner panel 44 are bent in a U-shape, and a vertical flange portion 442 orthogonal to the flat surface portion 441 of the inner panel 44 and a panel receiving portion 443 orthogonal to the vertical flange portion 442, Is provided. Since the inner panel 44 has a large thickness dimension, the vertical collar portion 442 formed by bending the inner panel 44 can be used as a vertical bone, and the rigidity required for the shoji 41 and 42 is ensured. For this reason, a longitudinal bone can be integrated with the inner side panel 44, and it is not necessary to provide a longitudinal bone separately.
As shown in FIG. 3, upper and lower bones 45 and 46 made of steel plate are fixed to the inner panel 44 at the upper and lower portions of the inner panel 44. Furthermore, when the width dimension of the inner panel 44 becomes large, the middle bone 47 is arranged at the center portion in the width direction of the inner panel 44 as necessary. The upper bone 45, the lower bone 46, and the middle bone 47 are also steel materials having thickness dimensions similar to those of the inner panel 44, and ensure the rigidity necessary for the aggregate.

  As shown in FIGS. 3 and 6, a door wheel 48 that moves on the protrusions 314 and 324 of the rail members 31 and 32 is attached to the lower bone 46. Since the door wheel 48 is a general door wheel made of stainless steel, the description thereof is omitted, and is schematically shown in the drawing. Instead of the door wheel 48, a structure in which a fluororesin sheet is bonded to the surface of the sliding metal fitting so as to be slidable on the protrusions 314 and 324 may be used.

The outer panel 43 is made of a steel plate that is thinner than the inner panel 44 and is fixed to the panel receiving portion 443 of the inner panel 44 with rivets. The outer panel 43 is a grooved wood carved steel plate in order to enhance the design of the shojis 41 and 42.
In the present embodiment, the above-described configuration is used. Conversely, the outer panel 43 is a steel plate having a thickness satisfying the structural specifications as a fire prevention equipment, and both end edges are bent in a U shape, and the inner panel 44 is processed. Alternatively, it may be configured by a steel plate having a small thickness dimension with emphasis on design.

As shown in FIGS. 4 and 10, the inner impingement 42 engages the outer impingement 41 and the reinforcing member 51 that engages with the vertical frame 23 of the joinery frame 20 when the outer impingement 41 and the inner impingement 42 are closed. And a reinforcing member 52. These reinforcing members 51 and 52 are made of a steel plate having a thickness dimension of t1.0 and bent in an L-shaped cross section.
The surfaces of these reinforcing materials 51 and 52 are covered with cover materials 511 and 521. The reinforcing members 51 and 52 and the cover members 511 and 521 are fixed to the inner panel 44 with rivets.
The cover members 511 and 521 are formed of the same steel plate as the outer panel 43 and cover a rivet or the like that fixes the outer panel 43.

As shown in FIGS. 4 and 11, the outer shoji 41 includes a reinforcing member 55 and a cover member 551 that engage with the reinforcing member 52 of the inner shroud 42. The reinforcing material 55 and the cover material 551 are the same members as the reinforcing material 51 and the cover material 511 of the inner shroud 42.
On the other hand, as shown in FIG. 12, the butting portion of the outer screen 41 is provided with a reinforcing material 56 that forms a convex portion on one of the outer screen 41 and a reinforcing material 57 that forms a concave portion on the other outer screen 41. These convex portions and concave portions are configured to be fitted.

That is, the vertical flange 442 on the butting portion side of one of the outer screens 41 has a cover material 541 that covers the fixing portion of the outer panel 43 and a cover material 542 that covers the end portion of the inner panel 44 on the butting portion side. Is fixed.
Further, a steel reinforcing material 56 bent in a U-shaped cross section is fixed to the vertical flange portion 442 of the inner panel 44 with a fixing screw 562, and the reinforcing material 56 is covered with a cover material 561.

In the vertical flange portion 442 on the side of the butted portion of the other external shoji 41, a steel reinforcing material 57 bent in a U-shaped cross section and a cover material 571 covering the surface of the reinforcing material 57 are provided on the opening side. It is provided in a direction facing the outer screen 41 and is fixed with rivets.
Therefore, when the outer screen 41 is closed and butted together, the reinforcing material 56 serving as the convex portion is inserted and disposed in the opening of the reinforcing material 57 serving as the 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 reinforcing material 56 does not come off from the reinforcing material 57, and a through hole is not generated between the external obstacles 41. For this reason, fireproof performance is securable.
In addition, the reinforcing members 52 and 55 are smoked also in the summing part of the external shoji 41 and the inner shingles 42, and the reinforcing material 51 and the engaging part 23C are also smoked in the summing part of the inner shoji 42 and the vertical frame 23. The space from the exterior side of the shoji 41 and 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 can be ensured.

  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.

As shown in FIG. 12, a lock 61 and a lock holder 62 are attached to a substantially central portion in the height direction of the vertical flange portion 442 on the butting side of the external shoji 41. The sickle-shaped deadbolt 611 appears and disappears by operating the lock on the lock 61 provided on one of the outer screens 41. The lock holder 62 provided on the other external shoji 41 has a receiving hole 621 into which the dead bolt 611 is inserted.
By closing the lock 61, the respective obstacles 41 are restrained so that they cannot move away from each other. Further, since the dead bolt 611 is inserted into the receiving hole 621, the respective obstacles 41 are restrained so that they cannot move to the exterior side or the interior side of the fire door 10.

  As shown in FIGS. 4 and 11, a piece-shaped angle member 65 is attached to the inner panel 44 of the outer panel 41. The angle member 65 abuts on the abutting member 66 attached to the inner impingement 42 when the outer obturator 41 is opened to a predetermined position, and is used to move the inner impingement 42 together with the outer obturator 41. The abutting material 66 protrudes to the inward side of the inner panel 44 and can abut against the vertical frame 23.

[Opening and closing the fire door]
When the external shoji 41 is opened, only the external shoji 41 moves at first, and when the angle member 65 comes into contact with the contact member 66, the inner shroud 42 also moves in conjunction with the movement of the external shoji 41. When the abutting member 66 comes into contact with the vertical frame 23, the outer shoji 41 and the inner shoji 42 stop. 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 so as to overlap in the inner and outer directions. The fully open position is a position at which the glass portion of the window 2 is completely 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 reinforcing member 57 of the summing portion of the outer shoji 41 is engaged with the reinforcing member 56 of the summing portion of the inner shroud 42. In conjunction with the movement of the external shoji 41, the inner shoji 42 also moves. Then, when the reinforcing material on the door end side of the inner impingement 42 contacts the vertical frame 23, the outer impingement 41 and the inner impingement 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 lower frame 22 includes a lower frame main body 220 and rail members 31 and 32, and the outer rail member 31 is disposed in the recessed groove portion 22 </ b> A of the lower frame main body 220 and placed on the upper surface of the adjustment screw 33. For this reason, the outer rail member 31 is only guided by the concave groove portion 22A, and is not fixed to the lower frame main body 220 with screws or the like. For this reason, if the external shovel 41 is removed, it can be easily attached to and detached from the lower frame main body 220.
Furthermore, since the inner rail member 32 is only placed in the concave groove portion 22B, the inner rail member 32 can be easily attached and detached.
Therefore, the rail members 31 and 32 can be easily replaced when the rail members 31 and 32 have to be replaced according to the type of shoji or when the rail members 31 and 32 are damaged. Further, the groove members 22A and 22B can be easily cleaned by removing the rail members 31 and 32.

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 the driver 35. 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 discharged 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. For this reason, it can prevent that the adjustment screw 33 inhibits 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 the screwdriver 35, the configuration of the adjusting member can be simplified and the cost can be further reduced. In addition, since the height of the adjusting screw 33 can be finely adjusted by the number of rotations by the driver 35, 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.

In addition, since the rail members 31 and 32 are made of an aluminum material, the rail members 31 and 32 having a complicated cross-sectional shape having the ridges 314 and 324 and the like are easily manufactured as compared with the case of being made of a steel material. it can.
Furthermore, since the rail members 31 and 32 are formed in a U-shaped cross section, the rigidity of the long rail members 31 and 32 can be secured, and distortion and deflection of the rails can be eliminated. Furthermore, since the rail members 31 and 32 can be brought into contact with the indoor side wall portion or the outdoor side wall portion of the concave groove portions 22A and 22B, the concave groove portion 22A, The rail members 31 and 32 do not move or rattle within 22B, and the shoji 41 and 42 can be moved stably.

  Thickness that satisfies the structural requirements required of the upper frame 21, the lower frame main body 220, the vertical frame 23, the inner panel 44 of the shoji 41 and 42, and the reinforcing members 51, 52, 55, 56, and 57 as fireproof equipment. Since the thermal expansion refractory material 60 is provided at the engaging portion of these members, the fireproof line can be reliably configured, and sufficient fireproof performance as the fire door 10 can be ensured. In particular, since the butt portion of the outer cover 41 has a concave-convex fitting structure by the reinforcing members 55 and 56, a gap is not generated in the butt portion even when 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 fixed to the outer wall 1, and the attachment workability | operativity 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.

  Since the shojis 41 and 42 are composed of the outer panel 43 and the inner panel 44, the upper bone 45, and the lower bone 46, the longitudinal bone can be eliminated and the assembling of the shojis 41 and 42 can be improved.

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.

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.

The rail members 31 and 32 are not limited to those formed in a substantially U-shaped cross section. For example, it may be formed in an L-shaped cross section, or may be a plate having only horizontal plane portions 311 and 321.
Moreover, although the lower frame main body 220 and the rail members 31 and 32 are made of different materials of steel and aluminum, both may be made of steel or made of aluminum. Good. For example, in the case of a joinery that does not require fire resistance, the lower frame main body 220 and the rail members 31 and 32 may be made of aluminum. These configurations also have the advantage that the rail members 31 and 32 can be easily replaced.

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.
