Description

The present invention relates to a face material mounting structure.

BACKGROUND ART Extruded cement boards (hereinafter referred to as ECP), which are popular general-purpose building materials, and autoclave-cured lightweight cellular concrete (hereinafter referred to as ALC) are widely used as outer wall materials and inner wall materials of building structures. ECP and ALC are excellent in waterproofness, airtightness, fire resistance and the like.

When ECP or ALC is used as the outer wall material, especially in an area with many earthquakes, there is a possibility that adjacent ECPs or ALCs may move relatively close to each other due to the deformation of the building structure due to the earthquake. Therefore, a relatively large joint is often provided between the adjacent ECPs and ALCs.

In order to improve the appearance and design of a building structure, ECP and ALC are used as an inner wall material, and a surface material for makeup such as stone or aluminum panel is installed on the outer wall of the inner wall. .. As a result, ECP or ALC is used as the outer wall to improve the waterproofness, airtightness, and fire resistance while improving the appearance of the building structure.

In the building structure as described above, the face material that constitutes the outer outer wall has a through hole in the panel portion or joint portion of the ECP or ALC that is the inner outer wall material, and the bolt is inserted into the through hole. It is generally installed by.

Patent Document 1 discloses a mounting structure for a face material as described above. This structure will be described with reference to FIG. The lower end surface of the extrusion-molded cement plate 100 at the approximate center in the width direction is supported by the L-shaped steel 105 via a support portion (locking block) 104. As a result, the extrusion-molded cement board 100 is swingably attached about the locking block 104 in a plane direction parallel to the side surface of the body.

A bolt insertion hole 100b reaching the hollow portion 100a is formed in the extrusion-molded cement plate 100, and a strip-shaped support plate 103 is fixed to the bolt insertion hole 100b. A sliding member 106 is sandwiched between the extruded cement board 100 and the support plate 103. A plurality of finishing material mounting base metal pieces 101 that are continuous horizontally in the width direction of the extruded cement plate 100 are provided in the height direction of the extruded cement plate 100 via a support plate 103, and the surface of the extruded cement plate 100. It is fixed at the central part in the lateral width direction.

The finishing material 102 is immovably fixed to the finishing material mounting base metal 101 via the finishing material mounting plate 107 by the dowel pins 108, while the upper end moves in the width direction of the extrusion molded cement board 100. It is possibly supported and is supported by the dowel pin 109. As a result, the finishing material 102 is movable and swingable in the surface direction, and is attached to the extrusion molded cement plate 100.

When an external force acts on the extrusion-molded cement board 100, the extrusion-molded cement board 100 swings around the locking block 104 in a plane direction parallel to the side surface of the body. Further, since the finishing material 102 is also movable and swingable and attached to the extrusion-molded cement board 100, even if a displacement occurs between the extrusion-molded cement board 100 and the finishing material 102, this displacement causes the finishing It is absorbed by the movement of the material 102 in the surface direction.

Japanese Patent No. 39055653

In the structure of Patent Document 1 as described above, the load of the finishing material 102 is supported by the extruded cement board 100. Therefore, the extrusion-molded cement board 100 cannot bear the load of the finishing material 102, and cracks or damages may occur.

In addition, the above-described structure is premised on that the lower end surface of the extrusion-molded cement board 100 in the approximate widthwise center is supported by the locking block 104, and the extrusion-molded cement board 100 swings around the locking block 104 during an earthquake. Since the structure of the extrusion-molded cement board 100 is installed, the length direction of the extrusion-molded cement board 100 matches the vertical direction, and it can only be used for vertical stretching, and the length direction matches the horizontal direction. However, it is difficult to deal with horizontal lining. Further, it is necessary to provide the locking block 104 at the lower end surface of the extruded cement board 100 at a substantially central position in the width direction. Due to the above factors, there is a problem that there are many restrictions on the allocation of the extrusion-molded cement board 100.

Further, since the finishing material 102 is attached to the extrusion molded cement board 100, if there are many restrictions on the allocation of the extrusion molding cement board 100 as described above, there are many restrictions on the shape and allocation of the finishing material 102.

Next, the fastener 5 will be described. As shown in FIG. 1A, a plurality of fasteners 5 (51, 52, 53) are attached to the seamless eye 3. The fastener 5 includes a fixed fastener 51 for receiving its own weight, a movable fastener 52 for receiving its own weight, and a fastener 53 for sliding. The self-weight receiving fixed fasteners 51 and the self-weight receiving movable fasteners 52 are fasteners for transmitting the load of the face material 7 to the blinds 3. The fixed fastener 51 for receiving its own weight is tightened immovably 3 immovably. As will be described later in detail, the movable fastener 52 for receiving its own weight is movably attached to the blind 3 in order to cope with thermal expansion of the blind 3 or the like. The slide fastener 53 is a fastener that is movably attached to the blind 3 in order to allow relative movement of the blind 3 and the face material 7 during an earthquake. Hereinafter, each fastener will be described in detail.

9(a) and 9(b) are a perspective view and a sectional view, respectively, showing a situation in which the fixed fastener 51 for receiving a self-weight is installed without eyes. As shown in FIG. 9, the self-weight receiving fixed fastener 51 includes a horizontal plate 51a and a side plate 51b, and the side plate 51b is joined to one side of the horizontal plate 51a so as to be perpendicular to the horizontal plate 51a. Has been done. The fixed fastener 51 for receiving its own weight is provided on the outer surface of the seamless member 3 such that the side plate 51b straddles the first outer wall portion 3h and the second outer wall portion 3i and partially closes the outer groove portion 3r. The plate 51a is arranged so as to project outward from the side plate 51b. Bolt holes 51c are formed in the side plate 51b at positions corresponding to the outer groove portions 3r.

The fixed fastener 51 for receiving its own weight is fixed to the blind 3 by the mounting bolt 30. The mounting bolt 30 includes a head portion 30a and a male screw portion 30b. The mounting bolt 30 is arranged such that the head portion 30a is located in the structural frame side and is housed in the outer groove portion 3r of the seamless 3 and the male screw portion 30b faces outward and is inserted through the bolt hole 51c of the side plate 51b. Has been done. The mounting bolt 30 is a square bolt. That is, the head portion 30a of the mounting bolt 30 has a height higher than the height width of the outer groove portion 3r of the blind 3 in the vertical direction so that the mounting bolt 30 does not rotate after the head portion 30a is installed in the outer groove portion 3r. It has a rectangular shape with slightly smaller sides. The length of the side extending in the vertical direction of the head portion 30a is larger than the width of the opening of the outer groove portion 3r, that is, the width between the tips of the first and second outer wall portions 3h and 3i. ..

A mounting nut 31 is screwed onto the male screw portion 30 b of the mounting bolt 30 via a washer 32. Since the head portion 30a of the mounting bolt 30 has a side that is larger than the width of the opening of the outer groove portion 3r, the head portion 30a of the mounting bolt 30 and the mounting nut 31 are provided with the first and The second outer wall portions 3h, 3i, the side plate 51b of the fixed fastener 51 for receiving the own weight, and the washer 32 are sandwiched.

In the fixed fastener 51 for receiving its own weight, the mounting bolt 30 and the mounting nut 31 are preferably tightly connected by torque management, for example, but it is not always necessary to manage torque. In this case, by using the locking nut 31 as a locking specification, there is no need to worry about loosening of bolts and nuts due to repeated vibration (amplitude) even if layer displacement due to an earthquake occurs in the future, so there is virtually no maintenance. Can be

As described above, in each of the plurality of self-weight receiving fixed fasteners 51, the head portion 30a of the mounting bolt 30 is engaged with the inner surfaces of the first and second outer wall portions 3h and 3i. Thereby, even if the pulling force acts on the fastener 5 in the direction opposite to the blind 3, the fastener 5 is not separated from the blind 3.

On the upper surface of the horizontal plate 51a of the fixed fastener 51 for receiving its own weight, a face material mounting plate 56 is swingably mounted in a horizontal plane by bolts and nuts 57. The face material 7 is attached to the face material attachment plate 56. As described above, in the present embodiment, the face material 7 is a stone material, and the face material fixing portion 54 provided so as to project vertically upward is provided on the upper surface of the face material mounting plate 56. The face material 7 is installed by being inserted into the mounting hole 7a formed in the lower surface and by mounting the face material 7 on the upper surface of the face material mounting plate 56.

In the present embodiment, the face material fixing portion 55 is also provided on the lower surface of the face material mounting plate 56 so as to project vertically downward, and the face material fixing portion 55 is the upper surface of the face material 7. It is inserted in the mounting hole 7b opened in. As will be described later, the blind 3 and the fixed fastener 51 for receiving its own weight are movable in the longitudinal direction of the blind 3 with respect to the face member 7 located therebelow.

In the self-weight receiving fixed fastener 51 shown in FIG. 9A, the restraint member 35 is installed in the outer groove portion 3r so as to contact both side edges of the side plate 51b positioned in the longitudinal direction of the seamless sheet 3. .. The restraint member 35 includes a bolt 36, a fixed steel plate 37, and a nut 38.

As shown in FIG. 10, the bolt 36 is a square bolt, and includes a head portion 36a and a male screw portion 36b. The bolt 36 is arranged such that the head portion 36a is located inside and is stored in the outer groove portion 3r, and the male screw portion 36b faces outward. The head portion 36a has a rectangular shape, and is formed such that at least the length of the side of the seamless portion 3 located in the height direction is larger than the width of the opening of the outer groove portion 3r.

A hole 37a is formed in the fixed steel plate 37. The fixed steel plate 37 is installed outside the first and second outer side wall portions 3h, 3i of the blind 3, and the male screw portion 36b of the bolt 36 protruding from the inside of the outer groove portion 3r is inserted through the hole 37a. There is. A nut 38 of a locking specification is screwed to the male screw portion 36b and is tightly fixed. The nut 38 may be a general hexagon nut as long as it is tightly connected by torque management.

Since the head portion 36a of the bolt 36 has a side that is larger than the width of the opening of the outer groove portion 3r, the first and second outer sides of the seamless 3 are provided between the head portion 36a of the bolt 36 and the nut 38. The walls 3h and 3i and the fixed steel plate 37 are sandwiched. Therefore, the restraint member 35 is installed in the blind 3 so that it cannot be easily moved in the longitudinal direction with respect to the blind 3.

The restraint member 35 thus configured fixes the self-weight receiving fixed fastener 51 shown in FIG.

Next, the movable fastener 52 for receiving its own weight shown in FIG. 1 will be described. The self-weight receiving movable fastener 52 is, like the self-weight receiving fixed fastener 51, for transmitting the load of the face material 7 to the blind portion 3. The self-weight receiving movable fastener 52 has a configuration similar to that of the self-weight receiving fixed fastener 51. However, in fixing the self-weight receiving fixed fastener 51, the mounting bolts 30 and the mounting nuts 31 are larger than those in the self-weight receiving fixed fastener 51. This is different from the self-weight receiving fixed fastener 51 in that it is loosely tightened and that the lateral side of the self-weight receiving movable fastener 52 is not fixed by the restraining member 35. Thereby, the movable fastener 52 for receiving its own weight is installed in the seamless part 3 so as to be movable in the longitudinal direction with respect to the seamless part 3.

In the present embodiment, when attaching one face material 7 to one seamless material 3, when the load of the face material 7 is supported by a plurality of fixed weight fasteners 51 for self weight reception and movable fasteners 52 for self weight reception In the above, only one of the fasteners attached to the blind 3 is the fixed fastener 51 for receiving its own weight, and the other is the movable fastener 52 for receiving its own weight. If a plurality of self-weight receiving fixed fasteners 51 are used, when the seamless material 3 and the face material 7 located between these self-weight receiving fixing fasteners 51 are thermally expanded, the difference in the thermal expansion coefficient between them causes no effect. The eye 3 and the face material 7 are stressed and may be damaged. Due to the configuration in which only one fixed fastener 51 for receiving the dead weight is used and the other movable fasteners 52 for receiving the dead weight are used, the movable fastener 52 for receiving the dead weight moves and absorbs stress during thermal expansion, and prevents damage due to thermal expansion. It is possible.

Next, the slide fastener 53 will be described. The slide fastener 53 is a fastener that is movably attached to the blind 3 in order to allow the blind 3 and the face material 7 to move relative to each other in the event of an earthquake. The slide fastener 53 is shown in FIG. The slide fastener 53 has the same structure as that of the movable fastener 52 for receiving its own weight. That is, the slide fastener 53 includes a horizontal plate 53a and a side plate 53b similarly to the dead weight fixed fastener 51 and the dead weight movable fastener 52, and is attached via a bolt hole 53c formed in the side plate 53b. It is mounted seamlessly 3 by a bolt 30, a mounting nut 31, and a washer 32. In the sliding fastener 53, the mounting bolt 30 and the mounting nut 31 are tightened more loosely than in the case of the fixed fastener 51 for receiving the own weight, and the lateral side of the sliding fastener 53 is not fixed by the restraining member 35.

With the above-mentioned configuration, the slide fastener 53 is installed in the blind 3 so as to be movable in the length direction with respect to the blind 3.

As described above, the slide fastener 53 has the same structure as the self-weight receiving movable fastener 52, but plays a different role from the self-weight receiving movable fastener 52. As described above, the movable fastener 52 for receiving its own weight is intended to prevent the damage due to thermal expansion while supporting the own weight of the face material 7, but the fastener 53 for sliding is blind when an earthquake occurs. The purpose is to allow relative movement of the blind 3 and the face material 7 with respect to.

Since the slide fastener 53 does not have to play the role of supporting the weight of the face material 7, the slide fastener 53 is mainly used above the face material 7 to attach the face material 7 invisible. .. Therefore, in the slide fastener 53, as shown in FIG. 11, the face material fixing portion 55 is provided on the slide fastener 53 in the same manner as the face weight fixing fastener 51 described with reference to FIG. It is provided on the lower surface of the plate 56, and the face material fixing portion 55 is inserted into the attachment hole 7d formed on the upper surface of the face material 7 to attach the face material 7 invisible.

In the present embodiment, the face material fixing portion 54 is also provided on the upper surface of the face material mounting plate 56 so as to project vertically upward, and the face material fixing portion 54 is the lower surface of the face material 7. It is inserted in the mounting hole 7c opened in. As will be described later, the upper surface member 7 joined by the fixed stitches 51 and the self-weight receiving fixed fastener 51 (not shown) is different from the lower surface member 7 and the sliding fastener 53 in the figure. The movable portion 3 is relatively movable in the length direction.

As described above, the plurality of fasteners 5 (51, 52, 53), especially the movable fastener 52 for receiving the own weight, and the slide fastener 53 are mounted by the mounting bolts 30 (hooking portions) that engage with the outer groove portions 3r (groove portions). , Is attached to the seamless member 3 and is movable relative to the seamless member 3 along the outer groove portion 3r.

How to attach the face material 7 to the structure composed of the seamless 3 and the self-weight receiving fixed fastener 51, the self-weight receiving movable fastener 52, and the slide fastener 53, that is, one face material The allocation of the fasteners 5 (51, 52, 53) to 7 will be described below.

Basically, the position of each fastener 5 (51, 52, 53) is determined by designing the surface material 7 and examining the strength. Since the wind pressure resistance performance differs depending on the layout and weight of the face material 7 and the mounting position, the system is highly dependent on the design, while being a system that can accommodate the design.

In the present embodiment, as shown in FIG. 1, the face material 7 has a height of a space between the upper and lower seamless parts 3, that is, between the horizontal members 2 located along the seamless part 3. It is a rectangular member having a height, and the upper side and the lower side are arranged so as to substantially follow each of the two horizontal members 2 adjacent in the height direction. For example, the face member 7A shown by the two-dot chain line in FIG. 1(a) has a lower side and an upper side each located near the lower side of the face member 7A, and the horizontal member 2B shown in FIG. 1(b). , And the horizontal member 2C located near the upper side of the face member 7A.

The face material 7A is attached at its lower end by one self-weight receiving fixed fastener 51A and one self-weight receiving movable fastener 52A attached to the seamless member 3B joined to the horizontal member 2B. The own weight is supported by the fasteners 51A and 52A. Further, the face material 7A is movably attached at its upper end to the seamless 3C by two slide fasteners 53A attached to the seamless 3C joined to the horizontal member 2C.

The other face material 7 provided at the same horizontal position as the face material 7A is also attached to the blinds 3B and 3C, like the face material 7A.

The face material 7B provided below the face material 7A and shown by the chain double-dashed line in FIG. 1(a) has its lower side and upper side located near the lower side of the face material 7B, respectively. It is arranged so as to be located near the horizontal member 2A shown in b) and the horizontal member 2B located near the upper side of the face material 7B.

The lower end of the face material 7B is placed on the waist wall 9, and the weight of the face material 7B is supported by the waist wall 9. Further, the face member 7B is movably attached at its upper end to the seamless 3B by two slide fasteners 53B attached to the seamless 3B joined to the horizontal member 2B.

The face members 7A and 7B arranged at different positions in the height direction, which are arranged as described above, are attached to the seamless member 3B by the self-weight receiving fixed fastener 51, Since the material 7B is attached to the seamless 3B by the slide fastener 53, the material 7B can move relative to each other.

FIG. 12(a) schematically shows the face material mounting structure 1 shown in FIG. In this figure, two face members 7 (7D, 7E) are attached to the three blinds 3 (3D, 3E, 3F) extending in the horizontal direction.

The blind 3E is located above the blind 3D. Further, the seamless 3F is located further above the seamless 3E.

The face material 7D is attached to the seamless 3D by a fixed fastener 51D for receiving its own weight and a movable fastener 52D for receiving its own weight. The face material 7D is attached to the seamless 3E by two slide fasteners 53D. As a result, the seamless 3D, the self-weight receiving fixed fastener 51D, the self-weight receiving movable fastener 52D, the face material 7D, and the sliding fastener 53D behave integrally.

The face material 7E is attached to the eye-free 3E by a fixed fastener 51E for receiving its own weight and a movable fastener 52E for receiving its own weight. The face material 7E is attached to the seamless 3F with two slide fasteners 53E. As a result, the seamless eye 3E, the self-weight receiving fixed fastener 51E, the self-weight receiving movable fastener 52E, the face material 7E, and the sliding fastener 53E behave integrally.

Needless to say, how to attach the fastener 5 and the face material 7 to the single eyeless piece 3 is not limited to this, and various other attaching methods can be considered without departing from the spirit of the present invention.

Next, the operation and effect of the above face material mounting structure 1 will be described with reference to FIGS. 1 and 12.

When an earthquake occurs and a lateral seismic force acts on the structural frame, the studs 8 are inclined due to the effect of interlayer displacement due to the distortion of the structural frame. Accordingly, the horizontal member 2 and the seamless member 3 located at different heights move relative to each other in the length direction of the horizontal member 2. As a result, the shape of the region, which is normally rectangular, in which the outer frame is formed by the horizontal members 2 and the blinds 3 that are vertically adjacent to each other and the studs 8 that are horizontally adjacent to each other, is transformed into a parallelogram. To do.

Here, the inner outer wall member 6 positioned between the vertically adjacent horizontal members 2 is placed on the lower horizontal member 2 and is sandwiched from above by the seamless member 3 attached below the upper horizontal member 2. It is provided by Further, the side edge of the inner outer wall member 6 is loosely fixed to the Z clip 21 fixed to the second joining member 11 shown in FIG. Therefore, the inner outer wall member 6 slides in the lengthwise direction of the horizontal member 2 with respect to the upper and lower horizontal members 2 and the blinds 3 to form a parallelogram in the region surrounded by the horizontal member 2 and the studs 8. It is possible to deal with deformation.

On the other hand, the face material 7 behaves as described below. Here, for example, the seamless 3E shown in FIG. 12A is moved relative to the seamless 3D, and the seamless 3F is relatively moved to the right with respect to the seamless 3D and the seamless 3E, respectively. Consider a case of interlayer deformation as shown in FIG. The same description as below can be applied to the case of relative movement in the left direction.

As described above, the seamless 3D, the self-weight receiving fixed fastener 51D, the self-weight receiving movable fastener 52D, the face material 7D, and the slide fastener 53D behave integrally. On the other hand, the seamless 3E tries to move to the right relative to the seamless 3D, the fixed fastener 51D for receiving its own weight, the movable fastener 52D for receiving its own weight, the face member 7D, and the fastener 53D for sliding. Here, the face material 7D is attached to the seamless 3E via a slide fastener 53D that is movable in the longitudinal direction relative to the seamless 3E. Therefore, the face material 7D and the seamless 3E can move relative to each other, and thus it is possible to cope with the influence of the interlayer displacement acting on the face material 7D.

As described above, the seamless eye 3E, the self-weight receiving fixed fastener 51E, the self-weight receiving movable fastener 52E, the face material 7E, and the slide fastener 53E behave integrally. Therefore, the self-weight receiving fixed fastener 51E, the self-weight receiving movable fastener 52E, the face material 7E, and the slide fastener 53E move to the right together with the blind 3E.

Further, the blind 3F tries to move further to the right than the blind 3E. Here, the face material 7E is attached to the seamless 3F via a slide fastener 53E that is movable relative to the seamless 3F in the longitudinal direction. Therefore, the face material 7E and the seamless 3F can be moved relative to each other, and thus it is possible to cope with the influence of the interlayer displacement acting on the face material 7E.

As described above, the slide fastener 53 is attached to the blind 3 by the hooking portion that engages with the outer groove 3r, that is, the mounting bolt 30, and is relatively attached to the blind 3 along the outer groove 3r. Since the movable member 3 is movable, even if the seamless member 3 or the horizontal member 2 on which the seamless member 3 is installed undergoes interlayer displacement due to an earthquake, the face member 7 attached to the fastener 5 has the seamless member 3 installed. It is possible to move relative to the horizontal member 2 and the seamless member 3. Therefore, it is possible to reduce the influence of the interlayer displacement on the face material 7, and prevent the face material 7 from being damaged or dropped.

Further, since the inner outer wall material 6 is provided by being sandwiched between the horizontal member 2 and the seamless member 3 located above and below, even if the interlayer displacement occurs in the seamless member 3 or the horizontal member 2 as described above, the inner outer wall material 6 6 slides in the lengthwise direction of the horizontal member 2 with respect to the upper and lower horizontal members 2 and the seamless member 3, and can cope with the deformation of the region surrounded by the horizontal member 2 and the studs 8 into a parallelogram. ..

Further, since the face material 7 is attached not to the inner outer wall material 6 but to the seamless 3 via the fastener 5, the inner outer wall material 6 does not have to bear the load of the face material 7.

Therefore, it is possible to prevent the inner outer wall material 6 from being cracked or damaged.

Further, it becomes possible to install the fastener 5 at an arbitrary position of the outer groove portion 3r on the seamless portion 3 and attach the face material 7 to the fastener 5. That is, since the degree of freedom in selecting the installation position of the fastener 5 is not constrained by the position or shape of the inner outer wall member 6 or the horizontal member 2, it is possible to increase the degree of freedom in the shape or allocation of the face member 7. ..

Further, as described above, since the shape of the face material 7 and the degree of freedom in allocation are high, the present structure can be standardly adopted regardless of the shape of the building. Therefore, it is possible to reduce the time and man-hours required for the determination and design of the face material mounting structure and the construction study, that is, the construction cost.

Further, since the inner outer wall material 6 is provided by being sandwiched between the horizontal member 2 and the seamless member 3 located above and below, the inner outer wall material 6 is horizontally stretched on the horizontal member 2 as described in the present embodiment. By installing and sliding the inner outer wall material 6 in the horizontal direction with respect to the horizontal member 2 at the time of an earthquake, it is possible to deal with interlayer displacement between the horizontal members 2 and the inner outer wall material 6 will be described later. As shown in the modified example of FIG. 5, the inner outer wall material 6 is supported vertically at the lower center position, and the inner outer wall material 6 is swung during an earthquake to cope with the interlayer displacement between the horizontal members 2 during an earthquake. Is also possible. This can increase the degree of freedom in allocating the inner and outer wall materials.

In addition, liquid such as rainwater that flows down on the horizontal member 2 and the blind 3 along the joints between the inner and outer wall members 6 adjacent to each other is transferred from the opening 3v on the upper surface of the blind 3 to the internal space 3o of the blind 3. The water can be introduced and discharged from the water discharge opening 3x on the lower surface of the seamless member 3. Therefore, since it is possible to realize drainage of rainwater with a simple structure, it is possible to reduce the construction cost.

Moreover, since the seamless member 3 can be attached to the horizontal member 2 by inserting the flange 2a of the horizontal member 2 into the gap 3t of the seamless member 3, the construction is easy and therefore the construction cost can be reduced. You can

Further, since the outer groove portion 3r is provided on the side surface on the side opposite to the structural body, that is, facing the outer side, the fastener 5 is provided on the side surface of the blind 3, which faces the outer side. For this reason, the face material 7 can be easily installed on the fastener 5, and thus the construction cost can be reduced.

Further, since ECP or the like, which is a popular general-purpose building material, is used as the inner outer wall material 6, the construction cost can be reduced.

Further, when attaching one face material 7 to one seamless member 3, one self weight receiving fixed fastener 51 and one self weight receiving movable fastener 52 support the self weight of the face material 7. It is installed to do. As a result, thermal expansion occurs due to the difference in the coefficient of thermal expansion between the seamless material 3 and the face material 7, and the damage due to the stress applied to the seamless material 3 and the face material 7 can be prevented.

Further, since each nut such as the mounting nut 31 used when the fasteners 5 (51, 52, 53) are attached to the blind 3 is a locking specification, it is not necessary to regularly re-tighten the nuts. It is possible to reduce maintenance and maintenance costs.

(First Modification of Embodiment)
Next, with reference to FIG. 13, a first modification of the face material mounting structure 1 shown as the above embodiment will be described. The difference between the face material mounting structure 60 according to the first modified example and the face material mounting structure 1 is that the number of inner outer wall members 6 provided between the horizontal members 2 vertically adjacent to each other is the same as the face material mounting structure 1. In contrast, the number of sheets in the face material mounting structure 60 is one, whereas the number of sheets is three in the above.
