Patent Description:
Patent Documents <NUM> to <NUM> disclose examples of a conventional mounting member for mounting a wall material. The mounting member (fastening fitting) disclosed in Patent Document <NUM> has a shape with a substantially C-shaped cross section, and includes a first side wall portion protruding from an upper edge of a substrate portion to the substrate portion, and a first abutting portion that is bent downward from a leading edge of the first side wall portion.

The mounting member (first fastening fitting) disclosed in Patent Document <NUM> can be equipped with an abutment member (lateral displacement prevention fitting) for preventing lateral displacement of a wall material (exterior wall plate). In the case of this mounting member, an upper horizontal portion is connected to a flat plate portion via an upper erect portion, and protrudes upward. The abutment member is temporarily mounted to the mounting member as a result of the upper horizontal portion being clamped by a backside locking piece and a lower fixing plate.

The mounting member (fastening jig body) disclosed in Patent Document <NUM> can be equipped with an abutment member (horizontal spacing plate). In the case of this mounting member, a fixing surface plate is formed on the backing member side with a step provided between a substrate portion (back plate) and the fixing surface plate. The abutment member is fixed to the fixing surface plate using a tapping screw. <CIT> discloses an outer wall board attachment for attaching to a building frame. <CIT> (being an intermediate document) a fixture that can increase the degree of layout freedom of a contact fitting and facilitate construction and that can suppress a reduction in the strength and the durability of a building structure, and a wall structure for buildings. <CIT> discloses an attaching fitting of exterior material which prevents the incursion of wind and rain to the inside of an outer wall by connecting a first base part abutted on a substrate material and a second base part having a projection piece and an exterior material locking part by a U-shaped lower end connection part. <CIT> discloses a vertical stretch structure for siding which improves an execution property by holding the right and left adjacent sidings together with side hook tools, and supporting the lower ends of the sidings on the flat faces of lower end support tools. <CIT> discloses an outer wall construction structure which prevents shifting of an outer wall plate fixed to a metal backing assembly with four sides rabbetted and is easily constructed at a low cost.

However, in the case of the mounting member described in Patent Document <NUM>, no abutment member is disclosed.

In the case of the mounting member described in Patent Document <NUM>, the abutment member is moved in a direction in which the abutment member approaches the structural body so as to be located at a position higher than the upper horizontal portion, and thereafter the abutment member is moved downward so as to clamp the lower fixing plate. Accordingly, the abutment member needs to be sandwiched on the backside of the mounting member, thus making a mounting operation troublesome.

Furthermore, the mounting member described in Patent Document <NUM> has a configuration in which a fixing surface plate is used, and the abutment member is fixed to the fixing surface plate using a tapping screw without being temporarily mounted, and therefore, there is the possibility that the abutment member will fall off during a mounting operation. Accordingly, it is difficult to perform a mounting operations with ease and safely.

The present invention has been made in view of the above-described conventional circumstances, and it is an object of the invention to provide a mounting member and an assembly that allow mounting operations to be performed with ease.

The present application provides an assembly and a building wall structure, as defined in the appended set of claims.

The assembly allows a mounting operation to be performed with ease.

The first and second clamping portions and the plate portion can be easily formed, for example, by bending a sheet metal. Also, the protruding portion can be reliably clamped by the first and second clamping portions while a worker is holding the plate portion.

Ventilation can be ensured in the surrounding region of the mounting member by the space between the back surface of the wall material and the substrate portion, and the through hole. Also, rainwater or the like that has reached the wall portion is allowed to flow downward through the through hole. As a result, it is possible to suppress a reduction in strength and durability of the wall material and the structural body.

Rainwater or the like that has reached the wall portion is allowed to flow in a direction away from the structural body due to the incline. In particular, when the wall portion has a through hole, rainwater or the like that has flown in a direction away from the structural body is allowed to flow downward through the through hole. As a result, it is possible to suppress a reduction in strength and durability of the wall material and the structural body.

A tapered leading end of the fastening member such as a screw that is inserted into the fixing hole is caught on the recess, and, thus, positional displacement of the fastening member relative to the fixing hole can be suppressed. As a result, the mounting operations can be performed more easily.

A mounting member and a building wall structure according to the present invention allow a mounting operation to be performed with ease.

In the following, Embodiments <NUM> to <NUM> of the present invention will be described with reference to the drawings. Note that, in <FIG>, a vertically upward direction is indicated as "UP", and a vertically downward direction is indicated as "DOWN". In addition, a horizontally leftward direction in a direction from the outdoor side to the indoor side in <FIG> is indicated as "LEFT", and a horizontally rightward direction is indicated as "RIGHT". The directions shown in <FIG> and subsequent drawings are indicated so as to correspond to <FIG>.

As shown in <FIG>, a wall structure according to Embodiment <NUM> is an example of a specific embodiment of a wall structure. This wall structure is formed by mounting a plurality of exterior wall plates <NUM> to a structural body <NUM> that forms a building such as a residence, a facility, or a warehouse, using mounting members <NUM> shown in <FIG>. Each exterior wall plate <NUM> is an example of the wall material. As shown in <FIG>, <FIG> and so forth, the exterior wall plate <NUM> is a wall material that itself has high strength and high rigidity, and forms an exterior wall of the building. Note that the wall material is not limited to an exterior wall plate, and may be, for example, a decorative plate for decorating the outside of the building, an indoor structural panel, an interior plate, or the like.

As shown in <FIG>, the structural body <NUM> may be, for example, a framework such as a steel framework. The structural body <NUM> is made up of a plurality of structural members. The structural members include a plurality of column members <NUM> arranged at predetermined intervals in the horizontal direction, and auxiliary members such as studs disposed between the column members <NUM>. A sectioned material made of steel such as C-shaped steel, or the like is used as the column members <NUM>, the studs, and the like. Note that the structural body <NUM> is not limited to the configuration of the present embodiment, and may be for example, a reinforced concrete or brick framework, or a wood building.

Heat insulation material <NUM> is provided between the column members <NUM>. The heat insulation material <NUM> is a fiber-based heat insulation material made of mineral wool fibers, glass wool fibers, or the like. The heat insulation material <NUM> may be a foamed plastic-based heat insulation material such as foamed polyurethane, foamed phenol, or foamed polystyrene.

A heat insulation board <NUM> and waterproof sheets <NUM> are laid on a surface of the heat insulation materials <NUM>. The heat insulation board <NUM> may be, for example, a plaster board having fire resistance and sound insulation, a composite plate of a plaster board and a foamed phenol plate, a foamed polystyrene board, or the like. Each of the waterproof sheets <NUM> is a known waterproof sheet. The heat insulation board <NUM> and the waterproof sheets <NUM> are mounted to the column members <NUM> and so forth, using set screws (not shown) or the like, extend in the vertical direction and the horizontal direction, and cover the column members <NUM> and the auxiliary members from the outdoor side. Note that the waterproof sheets <NUM> may be omitted.

The mounting members <NUM> according to Embodiment <NUM> are to be fixed to the outdoor side of the column members <NUM>, and are used for mounting a plurality of exterior wall plates <NUM> to the structural body <NUM> such that exterior wall plates <NUM> are disposed adjacent to each other in the vertical direction and the horizontal direction. Each mounting member <NUM> is an example of a specific embodiment of a mounting member.

The mounting members <NUM> are disposed between the column members <NUM> and the exterior wall plates <NUM>. The mounting members <NUM> are mounted to the column members <NUM> at predetermined intervals in the vertical direction, and each extend in the horizontal direction. As shown in <FIG>, <FIG> and so forth, each mounting member <NUM> is an elongated piece of material made of a metal. The mounting member <NUM> is produced by, for example, bending and pressing a metal plate material. Note that the material and the production method of the mounting member <NUM> are not limited to those described above, and can be selected as appropriate from various materials and production methods.

In the following description of the shape of the mounting member <NUM>, the vertical direction, the horizontal direction, and the indoor and outdoor directions are defined based on an orientation of the mounting member <NUM> that is fixed to the column member <NUM>, as shown in <FIG> and so forth.

As shown in <FIG>, the substrate portion <NUM> of each mounting member <NUM> has a rectangular shape having a length in the horizontal direction larger than a length in the vertical direction. The length of the substrate portion <NUM> in the horizontal direction is, for example, about <NUM> to <NUM>, but may be longer or shorter than this. For use, the mounting member <NUM> is cut as needed, depending on the installation location.

The substrate portion <NUM> is provided with a plurality of fixing holes <NUM> extending therethrough in the indoor-outdoor direction. The fixing holes <NUM> are disposed at substantially the center of the substrate portion <NUM> in the vertical direction, and are spaced apart from each other at predetermined intervals in the horizontal direction. The surface of the substrate portion <NUM> that faces in the indoor direction is a flat surface that can be abutted against the heat insulation board <NUM> and the column member <NUM>. The surface of the substrate portion <NUM> that faces in the outdoor direction is also a flat surface. As shown in <FIG> and <FIG>, a recess 11D is formed in the substrate portion <NUM> above the fixing holes <NUM>. The recess 11D is recessed in the shape of a groove extending in the indoor direction from the surface of the substrate portion <NUM> that faces in the outdoor direction, and extends linearly in a direction parallel to an upper edge 11B of the substrate portion <NUM>, or in other words, the horizontal direction.

As shown in <FIG>, the substrate portion <NUM> is abutted against the heat insulation board <NUM> in a state in which the substrate portion <NUM> extends in the horizontal direction. The substrate portion <NUM> is configured to be fastened to the column members <NUM> as a result of screws 10B serving as fastening members for the mounting member <NUM> being passed through given fixing holes <NUM> and screwed into the column members <NUM> via the heat insulation board <NUM>. In this manner, the substrate portion <NUM> of each mounting member <NUM> is configured to be fixed spanning a plurality of column members <NUM>. The fixing holes <NUM> serve to determine the fixing position of the mounting member <NUM> and to inhibit positional displacement thereof when the mounting member <NUM> is fixed to the column members <NUM>, thus facilitating an operation.

As shown in <FIG> and <FIG>, a wall portion <NUM> has a rectangular shape that is bent at a substantially right angle from a lower edge 11A of the substrate portion <NUM> so as to protrude in the outdoor direction, and that also extends in the horizontal direction. The lower edge 11A of the substrate portion <NUM> is an example of one side edge of the substrate portion. As shown in <FIG>, the wall portion <NUM> is provided with a through hole <NUM> extending therethrough in the vertical direction. Although illustration has been omitted, a plurality of through holes <NUM> are provided in the wall portion <NUM> at predetermined intervals in the horizontal direction.

A protruding portion <NUM> has a rectangular shape that is bent from the upper edge 11B of the substrate portion <NUM> so as to protrude in the outdoor direction, and that extends in the horizontal direction. The upper edge 11B of the substrate portion <NUM> is an example of another side edge of the substrate portion. Upper and lower surfaces of the protruding portion <NUM> are flat surfaces. In Embodiment <NUM>, the protruding portion <NUM> is formed from the upper edge 11B, which is the other side edge of the substrate portion; however, the protruding portion <NUM> may not necessarily be formed directly from the upper edge 11B, and may be formed from the other side edge side, or in other words, a region in the vicinity of the upper edge, including the upper edge.

A plate thickness T1 of the protruding portion <NUM> is the plate thickness of the metal plate material or the like that forms the mounting member <NUM>. The length of protrusion of the protruding portion <NUM> in the outdoor direction is named L13, and the length of protrusion of the wall portion <NUM> in the outdoor direction is named L12. The length L13 is set to be shorter than the length L12. That is, a leading edge of the protruding portion <NUM> is at a position closer to the substrate portion <NUM> than a leading edge 12A of the wall portion <NUM> is. Accordingly, a gap W2 is formed between the leading edge of the protruding portion <NUM> and a back surface 2B of the exterior wall plate <NUM>.

A supporting portion <NUM> is bent at a substantially right angle from the leading edge 12A of the wall portion <NUM>, extends upward so as to be opposed to the substrate portion <NUM> and to approach the protruding portion <NUM>. The supporting portion <NUM> has a rectangular shape having a length in the horizontal direction larger than a length in the vertical direction. The supporting portion <NUM> is substantially parallel to the substrate portion <NUM>. The surface of the supporting portion <NUM> that faces in the outdoor direction is a flat surface that can be abutted against the back surface 2B of the exterior wall plate <NUM>.

A plurality of first locking portions <NUM> and a second locking portion <NUM> are connected to an upper edge 14A of the supporting portion <NUM>. Each first locking portion <NUM> includes a part of a bearing portion <NUM> that is bent at a substantially right angle from the upper edge 14A of the supporting portion <NUM> so as to protrude in the outdoor direction, and a first locking piece 15B. The second locking portion <NUM> includes another part of the bearing portion <NUM> and a second locking piece 16B.

The first locking pieces 15B of the first locking portion <NUM> protrude so as to be downwardly inclined toward the outdoor direction as a result of the bearing portion <NUM> being cut out into a substantially C shape at a plurality of locations thereof and bent downward, or in other words, toward the wall portion <NUM> side, from a leading edge of the bearing portion <NUM>.

The second locking piece 16B of the second locking portion <NUM> protrudes so as to be upwardly inclined toward the outdoor direction as a result of being bent upward, or in other words, to the protruding portion <NUM> side, from the leading edge of the bearing portion <NUM>. The second locking piece 16B has a rectangular shape extending in the horizontal direction. As shown in <FIG> and <FIG>, the second locking piece 16B has slits <NUM> formed therein at a plurality of locations at intervals in the horizontal direction.

Each mounting member <NUM> can be equipped with an abutment member <NUM>. As shown in <FIG>, <FIG>, <FIG> and so forth, the abutment member <NUM> is to be mounted to any given location of the protruding portion <NUM> of the mounting member <NUM>, and is used for preventing the lateral displacement of the exterior wall plate <NUM>.

The abutment member <NUM> is produced by, for example, bending and pressing a metal plate material. Note that the material and the production method of the abutment member <NUM> are not limited to those described above, and can be selected as appropriate from various materials and production methods.

In the following description of the shape of the abutment member <NUM>, the vertical direction, the horizontal direction, and the indoor and outdoor directions are defined based on the orientation of the abutment member <NUM> that is fixed to the mounting member <NUM>, as shown in <FIG> and so forth.

As shown in <FIG> and <FIG>, the abutment member <NUM> includes a mounting portion <NUM>, an erect piece <NUM>, and a clamping portion <NUM>.

The mounting portion <NUM> has a substantially rectangular shape having a length in the horizontal direction larger than a length in the vertical direction. The surface of the mounting portion <NUM> that faces in the indoor direction is a flat surface that can be abutted against a surface of the substrate portion <NUM> of the mounting member <NUM> that faces in the outdoor direction.

The mounting portion <NUM> is provided with six fixing holes <NUM> extending therethrough in the indoor-outdoor direction. The fixing holes <NUM> are spaced apart from each other at predetermined intervals in the horizontal direction. The fixing holes <NUM> are disposed at substantially the center of the mounting portion <NUM> in the vertical direction. A screw 30B serving as a fastening member for the abutment member <NUM> is inserted into each of the fixing holes <NUM> when the abutment member <NUM> is fixed to the mounting member <NUM>.

The erect piece <NUM> is a substantially rectangular piece that is bent at a substantially right angle from a left edge of the mounting portion <NUM> so as to protrude in the outdoor direction, and that also extends in the vertical direction.

The clamping portion <NUM> includes an upper clamping portion 33U provided as a single piece with the mounting portion <NUM> on the upper edge side thereof, and a lower clamping portion 33D provided as a single piece with the mounting portion <NUM> on the lower edge side thereof. The upper clamping portion 33U and the lower clamping portion 33D have the same but mirrored shape. Therefore, the same reference numerals are given to the constituent elements of the upper clamping portion 33U and the constituent elements of the lower clamping portion 33D, and the descriptions thereof have been omitted or simplified.

Specifically, the upper clamping portion 33U includes a first clamping portion <NUM>, a second clamping portion <NUM>, a plate portion <NUM>, and an auxiliary erect piece <NUM>. The lower clamping portion 33D also includes a first clamping portion <NUM>, a second clamping portion <NUM>, a plate portion <NUM>, and an auxiliary erect piece <NUM>. The first clamping portion <NUM>, the second clamping portion <NUM>, the plate portion <NUM>, and the auxiliary erect piece <NUM> of the upper clamping portion 33U respectively have the same but mirrored shape as the first clamping portion <NUM>, the second clamping portion <NUM>, the plate portion <NUM>, and the auxiliary erect piece <NUM> of the lower clamping portion 33D. Therefore, the configuration of the upper clamping portion 33U will be described in detail, and the description of the configuration of the lower clamping portion 33D has been omitted.

As shown in <FIG>, at the upper clamping portion 33U, the first clamping portion <NUM> has a rectangular shape that is bent from an edge of the mounting portion <NUM> so as to protrude in the outdoor direction, and that extends in the horizontal direction. The surface of the first clamping portion <NUM> that is directed to the side opposite to the mounting portion <NUM> is a flat surface that can be abutted against the protruding portion <NUM>.

At the upper clamping portion 33U, the plate portion <NUM> is connected to a leading edge of the first clamping portion <NUM>. The plate portion <NUM> is bent from the leading edge of the first clamping portion <NUM>, and extends upward so as to be spaced apart from the mounting portion <NUM> and the first clamping portion <NUM>. The plate portion <NUM> has a substantially rectangular shape having a length in the horizontal direction larger than a length in the vertical direction.

At the upper clamping portion 33U, three second clamping portions <NUM> are formed on the plate portion <NUM>. The second clamping portions <NUM> are spaced apart from each other at predetermined intervals in the horizontal direction. Each second clamping portion <NUM> is formed by cutting out a part of the plate portion <NUM> and a part of the first clamping portion <NUM> into a substantially C shape to form a groove, and bending the inner portion of that groove from the plate portion <NUM>. The second clamping portion <NUM> is a substantially rectangular piece that is bent from the plate portion <NUM> so as to protrude in the indoor direction. That is, the plate portion <NUM> connects the first clamping portion <NUM> and the second clamping portion <NUM>.

As shown in <FIG>, the second clamping portion <NUM> extends parallel to the first clamping portion <NUM> so as to be opposed thereto. The surface of the second clamping portion <NUM> that is opposed to the first clamping portion <NUM> is a flat surface that can be abutted against the protruding portion <NUM> from the side opposite to the first clamping portion <NUM>.

As shown in <FIG>, the second clamping portion <NUM> is provided with a gap W1 that is substantially equal to the plate thickness T1 of the protruding portion <NUM> of the mounting member <NUM> between the first clamping portion <NUM> and the second clamping portion <NUM>.

The auxiliary erect piece <NUM> is a substantially rectangular piece that is bent at a substantially right angle from the left edge of the plate portion <NUM> so as to protrude in the outdoor direction, and that also extends in the vertical direction. The auxiliary erect piece <NUM> is disposed on the same plane as the erect piece <NUM>.

With the clamping portion <NUM> having such a configuration, the upper clamping portion 33U of the abutment member <NUM> is caused to approach the mounting member <NUM> from a direction intersecting the substrate portion <NUM>, or in other words, in a direction (direction indicated by an arrow Y1) from the outdoor side toward the indoor side as shown on the right side on the plane of paper in <FIG>, and the protruding portion <NUM> is moved into the gap W1 between the first clamping portion <NUM> and the second clamping portion <NUM> of the upper clamping portion 33U, whereby the first clamping portion <NUM> and the second clamping portion <NUM> of the upper clamping portion 33U clamp the protruding portion <NUM>.

As shown on the left side on the plane of paper in <FIG>, the lower clamping portion 33D of the abutment member <NUM> is caused to approach the mounting member <NUM> in a direction (direction indicated by the arrow Y1) from the outdoor side toward the indoor side, and the protruding portion <NUM> is moved into the gap W1 between the first clamping portion <NUM> and the second clamping portion <NUM> of the lower clamping portion 33D, whereby the first clamping portion <NUM> and the second clamping portion <NUM> of the lower clamping portion 33D clamp the protruding portion <NUM>.

In this manner, as a result of the clamping portion <NUM> clamping the protruding portion <NUM>, the abutment member <NUM> can easily be temporarily mounted to the protruding portion <NUM> of the mounting member <NUM>. In this state, as shown in <FIG> and <FIG>, the screw 30B passes through a given fixing hole <NUM>, and is fastened onto at least one of the substrate portion <NUM> and substantially the same plane 8P as the substrate portion <NUM> (to the front surface of the heat insulation board <NUM>). The screw 30B is an example of a fastening member.

In the example shown in <FIG> and <FIG>, the screw 30B is passed through the fixing hole <NUM>, and is screwed into the substrate portion <NUM>, whereby the mounting portion <NUM> is fastened to the substrate portion <NUM>. At this time, the recess 11D of the substrate portion <NUM> is disposed at a position where it passes through the center of the fixing hole <NUM> in a state in which the first clamping portion <NUM> and the second clamping portion <NUM> of the upper clamping portion 33U clamp the protruding portion <NUM> and the mounting portion <NUM> is opposed to the substrate portion <NUM>. Accordingly, a tapered leading end of the screw 30B that is inserted into the fixing hole <NUM> catches on the recess 11D, and, thus, positional displacement of the screw 30B relative to the fixing hole <NUM> can be suppressed.

In the example shown in <FIG>, the screw 30B is passed through the fixing hole <NUM>, and is screwed into the heat insulation board <NUM> and the column member <NUM>, whereby the mounting portion <NUM> is fastened on substantially the same plane 8P as the substrate portion <NUM> (to the front surface of the heat insulation board <NUM>). In this manner, the mounting portion <NUM> of the abutment member <NUM> can be fixed to any given position of the substrate portion <NUM> of the mounting member <NUM>.

As shown in <FIG>, each exterior wall plate <NUM> is a plate material having a quadrilateral shape, or more specifically, a horizontally elongated, substantially rectangular shape. In the present embodiment, the exterior wall plate <NUM> is made of a ceramic material including cement. Note that the material and the shape of the exterior wall plate <NUM> are not limited to those described above. For example, a metal material, a wood material, a resin material, or the like can be selected as appropriate as the material of the exterior wall plate <NUM>. As for the shape of the exterior wall plate <NUM>, a plate material having a quadrilateral shape, i.e., a vertically elongated, substantially rectangular shape can be selected as appropriate, for example.

A front surface 2F of the exterior wall plate <NUM> is, for example, an exterior surface provided with a design such as a brick pattern. A front horizontal joint portion <NUM> is formed at a left end portion of the exterior wall plate <NUM>. A back horizontal joint portion <NUM> is formed at a right end portion of the exterior wall plate <NUM>. A front vertical joint portion <NUM> is formed at a lower end portion of the exterior wall plate <NUM>. A back vertical joint portion <NUM> is formed at an upper end portion of the exterior wall plate <NUM>. Note that, in <FIG>, the sizes of the front horizontal joint portion <NUM>, the back horizontal joint portion <NUM>, the front vertical joint portion <NUM>, and the back vertical joint portion <NUM> are shown in an exaggerated manner, relative to the size of the exterior wall plate <NUM>.

The front horizonal joint portion <NUM> is recessed from the back surface 2B toward the front surface 2F of the exterior wall plate <NUM>, and extends in the vertical direction, that is, along the left end portion of the exterior wall plate <NUM>.

The back horizontal joint portion <NUM> is recessed from the front surface 2F toward the back surface 2B of the exterior wall plate <NUM>, and extends in the vertical direction, that is, along the right end portion of the exterior wall plate <NUM>. A caulking material <NUM> is provided on a flat surface of the back horizontal joint portion <NUM> that is directed in the outdoor direction. The caulking material <NUM> is provided linearly along the back horizontal joint portion <NUM>. Note that a caulking material is not essential, and the caulking material <NUM> may be omitted.

The front vertical joint portion <NUM> is recessed from the back surface 2B toward the front surface 2F of the exterior wall plate <NUM>, and extends in the horizontal direction, that is, along the lower end portion of the exterior wall plate <NUM>. An engagement recess 23A that is recessed upward in a substantially tapered shape is formed in the front vertical joint portion <NUM>.

The back vertical joint portion <NUM> is recessed from the front surface 2F toward the back surface 2B of the exterior wall plate <NUM>, and extends in the horizontal direction, that is, along the upper end portion of the exterior wall plate <NUM>. A caulking material <NUM> is provided on a flat surface of the back vertical joint portion <NUM> that is directed in the outdoor direction. The caulking material <NUM> is provided linearly along the back vertical joint portion <NUM>. Note that the caulking material is not essential, and the caulking material <NUM> may be omitted. An engagement protrusion 24A that protrudes upward in a substantially tapered shape is formed on the back vertical joint portion <NUM>, above the upper side of the caulking material <NUM>.

As shown in <FIG>, a vertical shiplap portion extending in the horizontal direction is formed between vertically adjacent exterior wall plates <NUM> as a result of the back vertical joint portion <NUM> of the lower exterior wall plate <NUM> and the front vertical joint portion <NUM> of the upper exterior wall plate <NUM> overlapping each other. Although the illustration has been omitted, a horizontal shiplap portion extending in the vertical direction is formed between horizontally adjacent exterior wall plates <NUM> as a result of the front horizontal joint portion <NUM> of the right exterior wall plate <NUM> and the back horizontal joint portion <NUM> of the left exterior wall plate <NUM> overlapping each other. That is, each exterior wall plate <NUM> is a plate material having a so-called "four-side shiplap structure", including the front horizontal joint portion <NUM>, the back horizontal joint portion <NUM>, the front vertical joint portion <NUM>, and the back vertical joint portion <NUM>.

As shown in <FIG>, <FIG>, and <FIG>, the exterior wall plates <NUM> are mounted to the structural body <NUM> in the following manner, using the mounting members <NUM>.

As shown in <FIG>, a plurality of mounting members <NUM> are mounted at positions on the lower side of the column members <NUM> so as to extend in the horizontal direction. Then, the plurality of exterior wall plates <NUM> are mounted to the mounting members <NUM> in a state in which the exterior wall plates <NUM> are disposed adjacent to each other in the horizontal direction. At this time, as shown in <FIG>, the lower end portions of the exterior wall plates <NUM> are supported by the mounting members <NUM> due to the second locking portions <NUM> of the mounting members <NUM> locking with the engagement recesses 23A. An engagement recess 23A is an example of another end portion of the exterior wall plate <NUM>.

Next, as shown in <FIG>, another plurality of mounting members <NUM> are mounted to the exterior wall plates <NUM> from above so as to extend in the horizontal direction. At this time, as shown in <FIG> and <FIG>, the upper end portions of the exterior wall plates <NUM> are supported by the mounting members <NUM> due to the first locking portions <NUM> of the mounting members <NUM> locking with the engagement protrusions 24A. An engagement protrusion 24A is an example of one end portion of the exterior wall plate <NUM>.

Then, to the upper mounting members <NUM>, a plurality of exterior wall plates <NUM> are further mounted in a state in which the exterior wall plates <NUM> are disposed adjacent to each other in the horizontal direction. Also at this time, as shown in <FIG> and <FIG>, the lower end portions of the exterior wall plates <NUM> are supported by the mounting members <NUM> due to the second locking portions <NUM> of the mounting members <NUM> locking with the engagement recesses 23A.

Here, the abutment member <NUM> is used when a plurality of exterior wall plates <NUM> are mounted in a state in which the exterior wall plates <NUM> are disposed adjacent to each other in the horizontal direction. As shown in <FIG>, in a state in which the erect piece <NUM> and the auxiliary erect pieces <NUM> are abutted from the right side against a right side end portion 2R of a specific exterior wall plate <NUM> (<NUM>) whose engagement recess 23A is locked by the second locking portion <NUM> of a mounting member <NUM>, the upper clamping portion 33U of the abutment member <NUM> is temporarily mounted to the protruding portion <NUM> of the mounting member <NUM>. Furthermore, a screw 30B is inserted into a fixing hole <NUM> and the recess 11D, and is screwed into the heat insulation board <NUM> and the column member <NUM>, whereby the mounting portion <NUM> is fastened to the substrate portion <NUM>. Accordingly, the specific exterior wall plate <NUM> (<NUM>) is prevented from being horizontally displaced to the right. Then, although the illustration has been omitted, another exterior wall plate <NUM> is disposed adjacent to the specific exterior wall plate <NUM> (<NUM>) from the right. That is, a left side end portion <NUM> (see <FIG>) of that exterior wall plate <NUM> is abutted from the right against the erect piece <NUM> and the auxiliary erect pieces <NUM>.

Although the illustration and the description have been omitted, the same also applies to a case where, in a state in which the erect piece <NUM> and the auxiliary erect pieces <NUM> are abutted from the right against the right side end portion 2R of the specific exterior wall plate <NUM> (<NUM>), the lower clamping portion 33D of the abutment member <NUM> may also be similarly temporarily mounted to the protruding portion <NUM> of the mounting member <NUM>, as shown in <FIG>.

In this manner, the mounting member <NUM> is configured to support corner portions of a plurality of exterior wall plates <NUM> that are abutted against each other, or in other words, four-side shiplap portions. In addition, as a result of the supporting portion <NUM> of the mounting member <NUM> being abutted against the back surface 2B of the exterior wall plate <NUM>, a ventilation space is secured between the wall surface of the structural body <NUM> and the back surface 2B of the exterior wall plate <NUM>.

By performing such an operation also for other exterior wall plates <NUM>, the exterior wall plates <NUM> are supported by the structural body <NUM> in a state in which the exterior wall plates <NUM> are disposed adjacent to each other in the vertical direction and the horizontal direction, and cover the wall surface of the structural body <NUM>.

With the mounting member <NUM> and the wall structure according to Embodiment <NUM>, the protruding portion <NUM> of the mounting member <NUM> can be clamped by the upper clamping portion 33U or the lower clamping portion 33D, each of which is a component of the clamping portion <NUM>, simply by causing the abutment member <NUM> to approach the substrate portion <NUM> by moving the abutment member <NUM> in the direction from the outdoor side toward the indoor side as indicated by the arrow Y1 in <FIG>. That is, the abutment member <NUM> can be easily temporarily mounted to the protruding portion <NUM> of the mounting member <NUM> from the outdoor side. Then, as shown in <FIG>, <FIG>, and <FIG>, the mounting portion <NUM> of the temporarily mounted abutment member <NUM> can be safely fixed, using the screw 30B, onto at least one of the substrate portion <NUM> and substantially the same plane 8P as the substrate portion <NUM> (to the front surface of the heat insulation board <NUM>).

As shown in <FIG>, with the mounting member <NUM> and the wall structure, the length L13 of protrusion of the protruding portion <NUM> from the substrate portion <NUM> is shorter than the length L12 of protrusion of the wall portion <NUM> from the substrate portion <NUM>, and it is therefore possible to easily achieve weight reduction.

Accordingly, the mounting member <NUM> and the wall structure according to Embodiment <NUM> allow a mounting operation to be performed with ease and safely, and can achieve weight reduction.

With the mounting member <NUM> and the wall structure, the gap W2 is formed between the leading edge of the protruding portion <NUM> and the back surface 2B of the exterior wall plate <NUM>. Accordingly, it is possible to ensure ventilation in the surrounding region of the mounting member <NUM>.

Furthermore, with the mounting member <NUM> and the wall structure, even if a worker should accidentally drop the abutment member <NUM> when temporarily mounting the abutment member <NUM>, the abutment member <NUM> can be received/caught by the wall portion <NUM>. Also, even if the gap W1 between the first clamping portion <NUM> and the second clamping portion <NUM> is larger than the plate thickness T1 of the protruding portion <NUM>, the clamping portion <NUM> is unlikely to fall off from the protruding portion <NUM> because the clamping portion <NUM> is stopped in abutment by the protruding portion <NUM>.

With the mounting member <NUM> and the wall structure, the first clamping portion <NUM>, the second clamping portion <NUM>, and the plate portion <NUM> included in the upper clamping portion 33U and the lower clamping portion 33D that constitute the clamping portion <NUM> can be easily formed, for example, by bending a sheet metal. Also, the protruding portion <NUM> can be reliably clamped by the first clamping portion <NUM> and the second clamping portion <NUM> while the worker is holding the plate portion <NUM>.

Furthermore, with the mounting member <NUM> and the wall structure, ventilation can be ensured in the surrounding region of the mounting member <NUM> by the through holes <NUM> of the wall portion <NUM>, and the space between the back surface 2B of the exterior wall plate <NUM> and the substrate portion <NUM>, as shown in <FIG>. In addition, rainwater or the like that has reached the wall portion <NUM> is allowed to flow downward through the through holes <NUM>. As a result, it is possible to suppress a reduction in strength and durability of the exterior wall plate <NUM> and the structural body <NUM>.

With the mounting member <NUM> and the wall structure, the recess 11D of the substrate portion <NUM> is disposed at a position where it passes through the center of the fixing hole <NUM> in a state in which the upper clamping portion 33U clamps the protruding portion <NUM> and the mounting portion <NUM> is opposed to the substrate portion <NUM>, as shown in <FIG> and <FIG>. Accordingly, a tapered leading end of the screw 30B that is inserted into the fixing hole <NUM> moves into the recess 11D, whereby positional displacement of the screw 30B relative to the fixing hole <NUM> can be suppressed. As a result, a mounting operation can be performed more easily and safely.

As shown in <FIG>, for a mounting member <NUM> and a wall structure according to Embodiment <NUM>, a mounting member <NUM> is used in place of the mounting member <NUM> according to Embodiment <NUM>, and an abutment member <NUM> is used in place of the abutment member <NUM> according to Embodiment <NUM>. The rest of the configuration of Embodiment <NUM> is the same as that of Embodiment <NUM>. Therefore, the same components as those of Embodiment <NUM> are denoted by the same reference numerals, and the descriptions thereof have been omitted or simplified.

The mounting member <NUM> according to Embodiment <NUM> includes a wall portion <NUM>, a folded piece 211C, and a protruding portion <NUM>. The rest of the configuration of the mounting member <NUM> is the same as that of the mounting member <NUM> according to Embodiment <NUM>.

The wall portion <NUM> is downwardly inclined so as to be spaced apart from the protruding portion <NUM> in a direction from the substrate portion <NUM> side toward the supporting portion <NUM> side. Specifically, as shown in <FIG>, an angle α formed by the wall portion <NUM> and an extension of the substrate portion <NUM> is set to <NUM> degrees. The angle α of <NUM> degrees is merely an example, and may be changed as appropriate. The rest of the configuration of the wall portion <NUM> is the same as that of the wall portion <NUM> according to Embodiment <NUM>.

The folded piece 211C is folded from the upper edge 11B of the substrate portion <NUM> so as to extend downward.

The protruding portion <NUM> protrudes to the same side as the wall portion <NUM>, not from the upper edge 11B, which is the other side edge of the substrate portion <NUM>, but from a side edge portion 11C that is bent from a lower edge of the folded piece 211C, which is formed by folding the upper edge 11B to the outdoor side. That is, in Embodiment <NUM>, the protruding portion <NUM> protrudes from a region located on the other side edge side of the substrate portion <NUM>. As shown in <FIG>, a length L213 of protrusion of the protruding portion <NUM> from the substrate portion <NUM> is set to be shorter than a length L212 of protrusion of the wall portion <NUM> from the substrate portion <NUM>. The rest of the configuration of the protruding portion <NUM> is the same as that of the protruding portion <NUM> according to Embodiment <NUM>.

<FIG> shows the abutment member <NUM> according to Embodiment <NUM>, and a mounting portion 231U of the abutment member <NUM> has a substantially rectangular shape having a length in the horizontal direction larger than a length in the vertical direction. The surface of the mounting portion 231U that faces in the indoor direction is a flat surface that can be abutted against the surface of the substrate portion <NUM> of the mounting member <NUM> that faces in the outdoor direction. The mounting portion 231U is provided with six fixing holes <NUM> extending therethrough in the indoor-outdoor direction. The fixing holes <NUM> are spaced apart from each other at predetermined intervals in the horizontal direction.

A mounting portion 231D has the same shape as the mounting portion 231U except that the mounting portion 231D is located at a lower position relative to the mounting portion 231U. The mounting portion 231U is located at a position that is displaced to the outdoor direction relative to the mounting portion 231D by an interval W4 corresponding to the plate thickness of the folded piece 211C.

An erect piece 232U is a substantially rectangular piece that is bent at a substantially right angle from a left edge of the mounting portion 231U so as to protrude in the outdoor direction, and that also extends in the vertical direction. An erect piece 232D is a substantially rectangular piece that is bent at a substantially right angle from a left edge of the mounting portion 231D so as to protrude in the outdoor direction, and that also extends in the vertical direction. The erect piece 232U and the erect piece 232D are disposed on the same plane.

A clamping portion <NUM> includes a first clamping portion <NUM>, a second clamping portion <NUM>, and a plate portion <NUM>. The first clamping portion <NUM> has a rectangular shape that is bent from an upper edge of the mounting portion 231D so as to protrude in the outdoor direction, and that also extends in the horizontal direction. As shown in <FIG>, the surface of the first clamping portion <NUM> that is directed to the side opposite to the mounting portion 231D is a flat surface that can be abutted against the protruding portion <NUM> from below. The second clamping portion <NUM> has a rectangular shape that is bent from a lower edge of the mounting portion 231U so as to protrude in the outdoor direction, and that also extends in the horizontal direction. As shown in <FIG>, the surface of the second clamping portion <NUM> that is directed to the side opposite to the mounting portion 231U is a flat surface that can be abutted against the protruding portion <NUM> from above. The plate portion <NUM> connects the first clamping portion <NUM> and the second clamping portion <NUM> on the side opposite to the mounting portions 231U and 231D. A gap W3 between the first clamping portion <NUM> and the second clamping portion <NUM> is the same as the gap W1 between the first clamping portion <NUM> and the second clamping portion <NUM> according to Embodiment <NUM>.

With the mounting member <NUM> and the wall structure according to Embodiment <NUM> having such a configuration, the protruding portion <NUM> of the mounting member <NUM> can be clamped by the first clamping portion <NUM> and the second clamping portion <NUM> of the clamping portion <NUM> simply by causing the abutment member <NUM> to approach the substrate portion <NUM> by moving the abutment member <NUM> in a direction from the outdoor side toward the indoor side as indicated by an arrow Y2 in <FIG>. That is, the abutment member <NUM> can be easily temporarily mounted to the protruding portion <NUM> of the mounting member <NUM> from the outdoor side. Then, the mounting portion 231D of the temporarily mounted abutment member <NUM> can be safely fixed to the substrate portion <NUM> using the screw 30B. Although the illustration has been omitted, the mounting portion 231U of the temporarily mounted abutment member <NUM> can be safely fixed, using the screw 30B, on substantially the same plane 8P as the substrate portion <NUM> (onto the front surface of the heat insulation board <NUM>).

With the mounting member <NUM> and the wall structure, the length L213 of protrusion of the protruding portion <NUM> from the substrate portion <NUM> is shorter than the length L212 of protrusion of the wall portion <NUM> from the substrate portion <NUM>, and it is therefore possible to easily achieve weight reduction.

Accordingly, as in the case of Embodiment <NUM>, the mounting member <NUM> and the wall structure according to Embodiment <NUM> also allow a mounting operation to be performed with ease and safely, and can realize weight reduction.

As shown in <FIG>, with the mounting member <NUM> and the wall structure, the side edge portion 11C of the substrate portion <NUM> is formed as the folded piece 211C, and therefore, the mounting member <NUM> has high rigidity. Furthermore, the wall portion <NUM> is downwardly inclined so as to be spaced apart from the protruding portion <NUM> in a direction from the substrate portion <NUM> side toward the supporting portion <NUM> side. Accordingly, rainwater or the like that has reached the wall portion <NUM> is allowed to flow in a direction away from the structural body <NUM> due to the incline. Then, the rainwater or the like that has flown in a direction away from the structural body <NUM> is allowed to flow downward through the through holes <NUM> formed in the wall portion <NUM>. As a result, it is possible to suppress a reduction in strength and durability of the exterior wall plate <NUM> and the structural body <NUM>.

As shown in <FIG>, for a mounting member <NUM> according to Embodiment <NUM>, protruding portions <NUM> are formed by a plurality of plate-shaped pieces that are made by making cuts extending downward from the upper edge 11B of the substrate portion <NUM> and bending the pieces toward the outdoor direction. The protruding portions <NUM> are disposed on the same plane as the substrate portion <NUM> at a position displaced downward relative to the upper edge 11B. That is, the protruding portions <NUM> protrude to the same side as the wall portion <NUM>, not from the upper edge 11B of the substrate portion <NUM>, but from the side edge portion 11C. The rest of the configuration of Embodiment <NUM> is the same as that of Embodiment <NUM>. Therefore, the same components as those of Embodiment <NUM> are denoted by the same reference numerals, and the descriptions thereof have been omitted or simplified.
