Description

  The present invention relates to a mounting structure and a mounting method for an exterior material to an outer wall of a building.

  In an existing building or a new building, an exterior material for enhancing the appearance design may be attached to the outside of the outer wall of the building. For example, the outer wall on the front side including the entrance door of the building and facing the passage on the front side of the building can be a so-called facade that becomes a symbolic outer wall that affects the exterior design of the building. An exterior material may be attached to a part of the facade. Note that, in a store having the ability to attract customers, an exterior material having an advertising bulletin board may be attached to the outer wall on the front side of the store.

  When attaching such exterior materials to the outer wall of the building, if a frame for attaching the exterior materials is provided on the outer periphery of the building separately from the building structural frame, it will be necessary to construct the foundation for that purpose. As a result, the load increases in terms of construction period and construction cost. Therefore, an exterior material attachment device for attaching an exterior material to the surface of a building has been proposed. This device is a device in which an attachment member is inserted through a hole penetrating the ALC outer wall and fixed to a building frame, and an exterior material is attached through a trunk edge member fixed to the attachment member. The mounting bracket is assembled with a fixed hardware and a slide hardware so as to be slidable in the length direction, and both are fixed by bolts provided in a direction crossing the plate so that the mounting bracket can be expanded and contracted in the length direction. The fixing hardware of the mounting bracket is such that a horizontally long hole provided in parallel with the longitudinal direction and a bolt hole drilled in the slide metal are made to coincide with each other, and the bolt is fixed to the horizontally long hole and the bolt hole (see, for example, Patent Document 1).

Japanese Patent No. 3709556

  However, the exterior material attachment device described in Patent Document 1 is a device that attaches the vertical trunk edge and the horizontal trunk edge to the exterior material attachment device, and attaches the exterior material to the vertical trunk edge and the horizontal trunk edge. There is no disclosure of how to install the exterior material. If it is assumed that the exterior material is fixed with bolts or the like to all of the vertical body edge and the horizontal body edge, it can be easily understood that it takes a lot of time to install the exterior material. In addition, the exterior material mounting apparatus described in Patent Document 1 has a fixed hardware and a slide hardware assembled in a slidable manner, and both are fixed by bolts provided in a direction across the plate so that the mounting bracket can be extended and contracted in the length direction. Therefore, it cannot be denied that the structure is complicated and the manufacturing cost is high.

  The present invention has been made in view of the above-described problems, and provides a mounting structure for an exterior material that has a favorable exterior material mounting property and a structure that is not complicated, and a mounting method for an exterior material that has an excellent exterior material mounting property. The purpose is that.

In order to achieve the above-mentioned object, one aspect of the exterior material mounting structure according to the present invention is characterized in that at least two take-out materials at upper and lower positions taken out from the outer wall of a building are used as a set of take-out materials. Two or more sets of take-out materials arranged at intervals in the width direction;
A vertical base material attached to each take-out material;
An exterior material including at least one set of horizontal rails at an upper and lower position fixed to two sets of the vertical base materials,
The vertical base material includes an engagement fitting on which the lower crosspiece is engaged and mounted, and a fixing fitting on which the upper horizontal crosspiece is fixed.

  According to this aspect, the exterior material is attached to the vertical base material that is attached to the carry-out material taken out from the outer wall of the building, so that the exterior material is attached separately from the building structural frame. It is not necessary to provide the frame on the outer periphery of the building, and a mounting structure for a simple exterior material can be provided. The building to which the exterior material is attached may be a newly-built building or an existing building, but in the case of a newly-built building, it is more preferable because the building can be constructed with the carry-out material taken out from the outer wall. . Here, examples of the take-out material include a gusset plate having a bolt hole.

  Here, “at least two take-out materials in the upper and lower positions as a set of take-out materials” means two or three or more take-out materials for fixing one vertical base material to the outer wall. Yes. In general, since the vertical base material is fixed to the outer wall of the building in a vertical posture, at least two carry-out materials are in a vertical relationship. Further, “two or more sets of take-out materials arranged at intervals in the width direction of the outer wall and the vertical base material attached to each set of the take-out materials” refers to the horizontal direction on the outer wall of the building. This means that two or more sets of take-out materials are provided at intervals in the width direction, and therefore two or more vertical base materials are attached. Furthermore, “the exterior material including at least one set of horizontal rails in the vertical position fixed to the two sets of vertical base materials” means two pieces arranged at intervals in the width direction of the outer wall of the building. Among the vertical base materials described above, two corresponding vertical base materials are used as a set of vertical base materials, and the exterior material is fixed to the set of vertical base materials. When a set of vertical base materials is long in the vertical direction, for example, a plurality of exterior materials having a rectangular planar shape can be fixed in the vertical direction with respect to the set of vertical base materials.

  The exterior material includes at least a pair of horizontal rails at the upper and lower positions, and the set of horizontal rails may be formed of a metal piece or a beam made of the same material as other members forming the exterior material. May be formed. For example, when a louver made of a plurality of vertical bars is attached to a set of horizontal bars to form an exterior material, and this louver is made of a wooden bar, the set of horizontal bars is a piece of metal. It may be a wooden crosspiece made of the same material as the louver.

  In the exterior material mounting structure according to this aspect, the vertical base material has an engagement fitting on which the lower horizontal rail is engaged and a fixing bracket on which the upper horizontal rail is fixed, in other words. For example, since the upper and lower horizontal rails are not all fixed to the vertical base material with bolts or the like, the mounting property of the exterior material to the vertical base material is improved. In addition, since the lower horizontal rail of the exterior material is placed in a state of being engaged with the engagement fitting attached to the vertical base material, the lower horizontal rail is not fixed with a bolt or the like. Is also mounted in such a manner that it cannot be pulled out from the engagement fitting.

Further, in another aspect of the exterior material mounting structure according to the present invention, the fixing bracket includes a bracket piece having a first bolt hole into which a bolt is screwed, and a lower portion of the bracket piece with respect to the first bolt hole. A bolt screwed from,
A second bolt hole formed in the upper horizontal rail is inserted from above into the bolt and is tightened with a nut.

  According to this aspect, since the bolt is fixed upward with respect to the metal piece forming the fixing metal, the bolt hole (second bolt hole) of the horizontal beam above the exterior material is opposed to the upward bolt. It is loosely fitted from above and can be easily tightened from above. The thickness of the first bolt hole of the metal piece is about several mm, and the wall surface of the bolt hole having a thickness of several mm is threaded. On the other hand, it is possible to fix the bolt that is screwed upward from below without dropping.

  Further, in another aspect of the exterior material mounting structure according to the present invention, the carry-out material is fixed to a structural frame of the building to which the outer wall is fixed, and is taken out from a joint of the outer wall. To do.

  According to this aspect, it is possible to take out the take-out material from the outer wall of the building without affecting the arrangement of the outer wall panels forming the outer wall. Panels made of ceramic siding material, metal siding material, etc. are attached to the outer wall panel in the vertical direction and width direction (horizontal direction) of the outer wall, and vertical joints are provided at predetermined intervals in the width direction of the outer wall. Is common. Therefore, at the position corresponding to the vertical joint, a take-out material made of a gusset plate or the like is fixed to the column beam or the like forming the structural frame by welding or the like, and the carry-out material is held from the structural case to the outside of the outer wall at the vertical joint. Can be put out.

  In another aspect of the exterior material mounting structure according to the present invention, two vertical base materials corresponding to the left and right sets of the take-out material are attached to a set of the take-out materials. Features.

  According to this aspect, since two vertical base materials corresponding to the left and right groups of the carry-out material are attached to a set of carry-out materials, the number of carry-out materials is as small as possible. The exterior material can be attached via the vertical base material. For example, in the case where four sets of carry-out materials are provided on one side of the outer wall of a building, two vertical base materials are attached to the two sets of carry-out materials in the center (for example, the left and right sides of the gusset plate A vertical base material is attached to the left and right ends of the set, and a total of six vertical base materials are attached, assuming that one vertical base material is attached. And if one exterior material is attached to two vertical base materials, for example, a total of 3 exterior materials can be attached.

Also, in another aspect of the exterior material mounting structure according to the present invention, each of the fixing bracket and the engagement bracket has an engagement piece that engages with a corner portion of the vertical base material,

  According to this aspect, both the fixing metal fitting and the engagement metal fitting have the engagement piece, and by engaging this engagement piece with the vertical base material, the fixing metal fitting or the engagement metal fitting is used as the vertical base material. On the other hand, bolts and nuts can be tightened with an electric screwdriver or the like while being prevented from rotating. As described above, since the metal fitting is prevented from being rotated, the fixing metal fitting and the engagement metal fitting can be fixed to the vertical base material only by a nut corresponding to one bolt, and a good assembling property can be obtained.

Another aspect of the exterior material mounting structure according to the present invention is characterized in that the exterior material comprises any one of the following forms:
(A) Exterior material having a set of horizontal rails and a plurality of louvers (B) Exterior material having a set of horizontal rails and a planting panel (C) Exterior material having a set of horizontal rails and a sliding door (D) Exterior material having a set of horizontal bars and an advertising bulletin board (E) Exterior material having a set of horizontal bars and a solar panel.

  According to this aspect, it is possible to apply an exterior material that can bring about an appearance design suitable for a building. Here, louvers can be applied to louvers of various materials such as resin louvers and metal louvers in addition to wooden louvers, and further include louvers having a plurality of vertical bars and louvers having a plurality of horizontal bars. .

Further, according to one aspect of the method of attaching the exterior material according to the present invention, at least two taken-out materials at the upper and lower positions taken out from the outer wall of the building are used as a set of taken-out materials, and the interval in the width direction of the outer wall is set. A vertical base material mounting step for attaching a vertical base material to each of two or more sets of carry-out materials placed and disposed,

  Also according to this aspect, in the exterior material mounting step, after placing the horizontal rail below the exterior material into engagement with the fitting, the vertical base is obtained by fixing the horizontal beam above the exterior material to the fixing bracket. The mounting property of the exterior material to the material is improved. Here, there are a plurality of forms in the metal fitting attachment process and the exterior material attachment process. One of the forms is a form in which all the exterior materials are continuously attached in the exterior material attachment process after attaching all the hardwares in the bracket attachment process to a plurality of vertical base materials attached to the outer wall. It is. Moreover, another form is a form which repeats a metal fitting attachment process and an exterior material attachment process alternately. For example, after attaching only the metal fitting corresponding to one exterior material to the vertical base material in the metal attachment attaching process, this one exterior material is attached as the exterior material attaching process, and this is similarly performed for other exterior materials. It is a form.

Further, in another aspect of the exterior material mounting method according to the present invention, the fixing bracket includes a bracket piece having a first bolt hole into which a bolt is screwed, and a lower portion of the bracket piece with respect to the first bolt hole. A bolt screwed from,
In the exterior material attaching step, by temporarily inserting the second bolt hole formed in the upper horizontal rail to the bolt of the fixing bracket from above, the horizontal rail is temporarily fixed to the fixing bracket, It is characterized by being permanently fixed by tightening a nut.

  According to this aspect, since the bolt is fixed upward with respect to the metal piece forming the fixing metal, the second bolt hole of the horizontal rail above the exterior material can be easily formed from above with respect to the upward bolt. And can be easily tightened with nuts from above. For this reason, a good mounting property of the exterior material can be obtained.

  Hereinafter, a mounting structure and mounting method for an exterior material according to an embodiment will be described with reference to the accompanying drawings. In addition, in this specification and drawing, about the substantially same component, the duplicate description may be abbreviate | omitted by attaching | subjecting the same code | symbol.

[Mounting method and structure of exterior material according to embodiment]
With reference to FIG. 1 thru | or FIG. 7, the attachment method and attachment structure of the exterior material which concern on embodiment are demonstrated. Here, FIG. 1, FIG. 4 and FIG. 7 are process diagrams for explaining the mounting method of the exterior material according to the embodiment in order, and FIG. 7 shows both the mounting structure of the exterior material constructed by this mounting method. FIG. In each figure, the pattern of the outer wall panel is shown around the side surface to which the exterior material of the facade 10 is attached, and the pattern of the pattern on the other wall is not shown.

  In the description of the mounting method and mounting structure of the exterior material according to the embodiment, the object will be described below as a steel-framed two-story house. In the house 100 shown in FIG. 1, the side of the outer wall that has the entrance door 101 and the entrance is recessed in the back side is the facade 10 (symbol in appearance) of the house 100. A part of the outer wall region projecting outward is defined as an attachment region for the exterior material. The housing 100 is constructed by attaching an outer wall panel 11 having a rectangular planar shape made of a ceramic siding material or the like in a vertical direction and a horizontal direction (width direction) with respect to a structural frame formed of through pillars and large beams (not shown). Its outer wall is formed. The structural frame forms, for example, a portal frame, which is a basic skeleton, by connecting a large beam formed of a shape steel material such as H-shaped steel to a column formed of, for example, a square steel pipe with a bolt or the like. In addition, the gate-type frame or the like is configured by incorporating a brace material formed from a die steel material or the like, a ladder-type load-bearing wall frame, or the like.

  Vertical joints 12 are formed between the rows of the plurality of outer wall panels 11 stacked in the vertical direction. In the illustrated example, a vertical joint 12 is provided for each outer wall panel 11 stacked in two rows in the vertical direction. In each vertical joint 12, three take-out materials 20 are taken out at intervals in the attachment region of the exterior material above the facade 10 (upper half of the side surface). Accordingly, a total of nine carry-out members 20 are shown for the three vertical joints 12. The number of the carry-out materials 20 is set according to the rigidity of the carry-out materials 20 and the weight of the exterior material supported by each carry-out material 20. For example, one vertical base material is supported by the two upper and lower carry-out materials 20. There may be.

  The take-out material 20 is formed of a gusset plate having bolt holes, and is connected to a column made of, for example, a square steel pipe or the like forming a structural frame by welding or the like. In the newly built house 100, the gusset plate 20 is taken out from the vertical base material 12 in anticipation of the mounting of the exterior material. Further, in the existing house 100, the outer wall panel 11 around the vertical joint 12 is removed to expose the side surface of the pillar, and the gusset plate 20 is fixed to the pillar while reinforcing the pillar as necessary. By attaching the panel 11 again, the gusset plate 20 is taken out.

  By positioning the take-out material 20 on the vertical joint 12, the take-out material 20 can be taken out without hindering the arrangement of the outer wall panels 11 arranged in the vertical direction and the horizontal direction. In addition, although illustration is abbreviate | omitted, the form which takes out a carrying-out material from a horizontal joint on the side surface which has a horizontal joint other than the vertical joint 12 may be sufficient.

  Next, with reference to FIG.2 and FIG.3, the vertical base material fixed to the some carrying-out material 20 carried out from each vertical joint 12 is demonstrated. Here, FIG. 2 is a perspective view of an example of the vertical base material to which the fixing metal fitting and the engagement metal fitting are attached, and FIG. 3 is a view taken along arrow III-III in FIG. The illustrated vertical base material 30 is formed of angle steel. In one metal piece of angle iron, six bolt holes 31 of 2 × 3 sets in total are opened at positions corresponding to the bolt holes of three gusset plates 20 taken out from one vertical joint 12. Has been.

  On the other hand, on the other metal piece of the angle steel 30, a fixing bracket 40 is fixed with a bolt nut 61 via a bolt hole (not shown) above, and an engagement metal fitting 50 below the bolt hole (not shown). It is fixed with a bolt nut 62.

  That is, in the attachment method of the illustrated example, prior to the attachment of the vertical base material 30 to the carry-out material 20, the fixing metal fitting 40 and the engagement metal fitting 50 are grounded to the vertical base material 30. Therefore, in the mounting method of the illustrated example, when the four vertical foundation members 30 are attached to the outer wall of the house 100, the fixing bracket 40 and the engagement fitting 50 are attached to the four vertical foundation members 30 in advance.

  The fixture 40 is manufactured in a three-dimensional shape by cutting and bending the steel plate. The fixing bracket 40 includes an attachment piece 41 that is bolted to the vertical base material 30, a fixing piece 42 to which the exterior material is fixed, and an engagement piece 43 that engages with a corner of the vertical base material 30. . As shown in FIG. 3, the first bolt hole 42 a provided in the fixed piece 42 is provided with a screw cut in the hole wall surface, and the bolt 63 is screwed from below to be fixed to the fixed piece 42. That is, not only the fixing bracket 40 is attached to the vertical base material 30 but also the vertical base material 30 is attached to the carry-out member 20 in a state where the bolt 63 is fixed to the fixing bracket 40 in a posture facing upward. .

  For example, the thread 63 of the bolt 63 is only screwed into the threaded portion of the thick portion of the fixed piece 42 of about several mm, but the upward bolt 63 falls downward by both screws. Without being fixed, the state of being fixed to the fixing piece 42 of the fixing bracket 40 can be maintained.

  As shown in FIG. 3, after the vertical base material 30 is attached to the take-out material 20, the bolt 63 that is fixed in an upward posture to the fixing bracket 40 that is already attached to the vertical base material 30, Bolt holes in the upper horizontal rail (see FIGS. 5 and 6) forming the exterior material are inserted and fastened and fixed by nuts 64.

  On the other hand, the engagement fitting 50 is also manufactured in a three-dimensional shape by subjecting the steel plate to cutting and bending. The engagement metal fitting 50 is engaged with the mounting piece 51 that is bolted to the vertical base material 30, the placement piece 52 that is placed in a state where the exterior material is engaged, and the corner of the vertical base material 30. Engaging piece 53. The mounting piece 52 has a step shape, is bent 90 degrees from the mounting piece 51 extending in the vertical direction, extends in the horizontal direction, is further bent 90 degrees, and extends in the vertical direction. A lower horizontal rail (see FIG. 5) that forms the exterior material is engaged with the metal piece extending in the vertical direction.

  The engaging piece 43 of the fixing metal fitting 40 and the engaging piece 53 of the engaging metal fitting 50 are both engaged with the corners of the angle piece metal pieces forming the vertical base material 30. In this way, the fixing bracket 40 and the engagement bracket 50 are engaged with one corner portion of the vertical base material 30 via the engagement pieces 43 and 53, so that the respective mounting pieces 41 and 51 are connected to the vertical base material. Even if it fixes to 30 with one bolt nut, the correct attitude | position of the fixing metal fitting 40 and the engagement metal fitting 50 can be hold | maintained. If the engagement pieces 43 and 53 are not provided, the horizontal posture of the fixed piece 42 and the vertical posture of the mounting piece 52 are correctly held unless the mounting pieces 41 and 51 are fixed with two or more bolts and nuts. It is difficult to rotate them immediately, and it may be troublesome to change these postures to the correct postures when the exterior material is attached.

  In addition, with the engaging pieces 43 and 53 engaged with one corner of the vertical base material 30, the fixing bracket 40 and the engaging bracket 50 are nut-tightened with an electric screwdriver or the like. In this case, it is eliminated that the fixing metal fitting 40 and the engagement metal fitting 50 rotate together, and quick installation can be realized.

  Next, as shown in FIG. 4, the vertical base material 30 on which the fixing metal fitting 40 and the engagement metal fitting 50 are grounded is attached to a mounting position via a temporary scaffold (not shown) or an aerial work vehicle or the like. It conveys and it attaches with respect to one set of taking-out material 20 in the position of the upper middle which is taken out from each vertical joint 12. The vertical base material 30 is attached by positioning the bolt holes of each gusset plate 20 and the corresponding bolt holes of the vertical base material 30 and fixing them with bolts.

  In FIG. 4, one vertical base material 30 is attached to each pair of the left and right carry-out materials 20. More specifically, the vertical base material 30 shown in FIG. 2 is attached to the three take-out members 20 in the left end group in FIG. 2 is a vertical base material having a line-symmetrical relationship with the vertical base material 30 shown in FIG. 2 (in FIG. 2, the metal piece attached to the take-out material 20 is on the opposite side, and the fixing metal fitting 40 and the engagement metal fitting 50 are A configuration in which the engaging pieces 43 and 53 are engaged with the opposite corners) is attached.

  Further, in FIG. 4, a vertical base material 30 is disposed on the left and right sides of the set of three carry-out members 20 at the center to fix them. That is, the set of three carry-out members 20 in the center supports the two vertical base materials 30 for fixing the left and right exterior members disposed on the left and right sides thereof. Therefore, it is possible to attach a plurality of exterior materials while reducing the number of carry-out materials 20 as much as possible. The illustrated example is a form having one set of a central set of take-out materials 20 that support two vertical base materials 30, but in a building where the facade spreads in the horizontal direction, the take-out materials 20 corresponding to the center set shown in the figure. This effect becomes more remarkable in the form in which the number of (a pair of carry-out beams that support the left and right exterior materials) is further increased.

  As described above, the installation preparation of the exterior material is completed by attaching the specific vertical base material 30 to each set of the carry-out material 20 taken out from the vertical joint 12 of the outer wall of the building 100. In FIG. 4, four vertical base materials 30 are attached to the facade 10, and one exterior material is supported on a set of vertical base materials 30 composed of two vertical base materials 30 ( Above, vertical base material attachment process).

  Next, an example of the exterior material attached to the vertical base material 30 will be described with reference to FIGS. The exterior material 90 shown in the figure is disposed in the horizontal direction with an interval between an upper horizontal beam 71 formed from the lip channel steel and a lower horizontal beam 72 similarly formed from the lip channel steel, And a plurality of vertical louvers 80 fixed to the upper and lower horizontal bars 71, 72.

  As shown in FIG. 5, the upper horizontal rail 71 is assembled with the lip channel steel opening facing upward, while the lower horizontal beam 72 has the lip channel steel opening downward. It is assembled in a posture. As shown in FIG. 6, the upper horizontal rail 71 is inserted with a bolt 63 (see FIG. 2) that is fixed in an upward orientation with respect to the fixture 40 attached to the vertical base material 30. The second bolt hole 71a is provided. Further, as shown in FIG. 5, the lower horizontal rail 72 is formed by bending a part of the metal piece on the vertical louver 80 side of the lip groove steel, and with the vertical louver 80 at the bent portion. An engagement recess 72a that forms a gap therebetween is formed. Note that the lower horizontal rail 72 may not have the engagement recess 72a as in the illustrated example. In this form, for example, in the mounting piece 52 shown in FIG. 2, so that the vertical louver 80 and the mounting piece 52 at the end of the exterior material 90 placed on the mounting piece 52 of the engagement metal fitting 50 do not interfere with each other. Applying an engagement fitting having a mounting piece from which the left and right half pieces are cut from the center, the exterior member 90 is applied to the engagement fitting in such a form that the placement piece escapes from the vertical louver 80. Placed.

  As described above, the exterior material 90 is fixed to the upper and lower horizontal bars 71 and 72, and members (in the illustrated example, a plurality of vertical louvers 80) that are fixed to the horizontal bars 71 and 72 and exhibit various appearance design properties. Have The vertical louver 80 can be made of various materials such as wood, resin, and metal, and has a unique appearance design and atmosphere for each material. Moreover, instead of arranging the vertical louvers 80 orthogonally as in the illustrated example, the horizontal bars 71 and 72 may be arranged in an oblique direction, or vertical louvers such as round bars are applied. This will create a warm atmosphere. Further, for example, when the vertical louver 80 is made of a wooden crosspiece, the upper and lower horizontal crosspieces 71 and 72 are also made of the same material wooden crosspiece, whereby the exterior material 90 having a unified feeling can be formed as a whole.

  As described above, the exterior material 90 may have various forms, but other forms are illustrated below while omitting illustration.

It may be. Moreover, the exterior material which has a solar panel can bring out a technological image by not only the electric power generation by a solar panel but the solar panel being exposed to a wall surface.

  As shown in FIG. 7, by fixing one exterior material 90 to the two vertical base materials 30, in the illustrated example, the exterior material is attached to the facade 10 with the two exterior materials 90, and according to the embodiment. An exterior material mounting structure 200 is formed.

  The attachment method of the exterior material 90 to the vertical foundation material 30 will be described in more detail. For example, an operator riding on an aerial work vehicle moves the engagement recess 72a of the lower horizontal rail 72 in the gripped exterior material 90 to the vertical foundation. By inserting into the mounting piece 52 of the engagement metal fitting 50 attached to the material 30 (Z direction in FIG. 5), the exterior material 90 is engaged with the left and right engagement metal fittings 50. With the mounting piece 52 inserted into the engagement recess 72a in this way, the crosspiece 71 above the exterior material 90 is carried above the fixed piece 42 and is fixed to the fixing bracket 40 while facing upward. By inserting the second bolt hole 71 a of the horizontal rail 71 into the bolt 63, the exterior material 90 is temporarily fixed to the left and right vertical base materials 30.

  As described above, when the exterior material 90 is attached, the upper and lower surfaces of the exterior material 90 are not bolted to the vertical base material 30, but the lower part of the exterior material 90 is engaged and placed on the engagement fitting 50, By fixing the bolts to the fixing bracket 40 only upward, the mounting property of the exterior material 90 is improved. And this favorable attachment property becomes more remarkable as the area of the exterior material 90 increases or the number of the exterior materials 90 increases.

  Further, when the exterior material 90 is attached, the bolt 63 is already fixed to the upper fixing bracket 40 so as to face upward, so that the second bolt hole 71a of the upper horizontal rail 71 is inserted into the bolt 63. In addition, the nut can be quickly tightened, and this also provides excellent mounting properties.

  Note that the attachment method in the illustrated example is a method in which the fixing base 40 and the engagement fitting 50 are grounded with respect to the vertical base material 30 and attached to the take-out material 20 in the vertical base material mounting step. The attachment method may be used. Specifically, the vertical base material step for attaching the vertical base material 30 on which the fixing metal fitting 40 and the engagement metal fitting 50 are not grounded, and then attaching the fixing metal fitting 40 and the engagement metal fitting 50 to the vertical base material 30. An attachment method having a metal fitting attachment step and an exterior material attachment step of attaching the exterior material 90 to the vertical base material 30 can be mentioned. This attachment method further has two forms. In one form, after attaching all the metal fittings to the plurality of vertical base materials 30 attached to the outer wall in the metal fitting attaching process, all the exterior materials 90 are continuously attached in the exterior material attaching process. It is a form to attach. Moreover, another form is a form which repeats a metal fitting attachment process and an exterior material attachment process alternately. For example, after the fixing metal fitting 40 and the engagement metal fitting 50 corresponding to one exterior material 90 are attached to the vertical base material 30 in the metal attachment attachment process, this one exterior material 90 is attached as an exterior material attachment process, It is the form performed similarly also with respect to the exterior material 90. FIG. Even if it is the attachment method of any form, the outstanding attachment property is show | played.
