[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching an exterior material to an exterior wall of a building such as a house.

[0002]

2. Description of the Related Art In recent years, on the outer wall of a wooden house or the like,
Instead of spraying mortar on the outer surface of the outer wall, a plate-like exterior material is attached to the wall surface. Also,
2. Description of the Related Art In general, in the construction of a house, a panel construction method for building a floor, a wall, a roof, and the like of a house by assembling a wooden panel manufactured in a factory or the like in advance on the site is known.
Further, in the panel construction method, a large-sized connection panel is manufactured by connecting a plurality of wood panels in advance in a factory or the like, so that the work of joining the wood panels on site is labor-saving.

Further, in the above panel construction method, a sash frame such as a window, a glass shoji to be fitted into the sash frame, or the like is mounted on a large connecting panel (hereinafter referred to as a wall panel) constituting a wall of a house in a factory or the like in advance. Attaching fittings and attaching at least a part of a waterproof sheet or an exterior material (siding) to the outer surface of the wall panel has been performed to save labor for attaching fittings and exterior materials on site. By doing so, it is possible to improve the quality of the house and homogenize the quality of the house, to save labor on site work, and to shorten the construction period at the site.

Conventionally, as a method of attaching the fittings and exterior materials to a large-sized connecting panel in which wood panels are connected as described above, or a wall panel composed of a large panel formed as one panel from the beginning, the present applicant has For example, a sash frame and siding factory outfitting method described in Japanese Patent Application Laid-Open No. 10-245912 has already been proposed. In the method described in the above publication, a waterproof sheet, a rim (a thin plate-shaped member interposed between a siding and a wall panel), a siding and the like are attached to a wall panel at a factory, and a sash frame and a casing ( A member located outside the sash frame),
A glass shoji (for example, a window glass portion that opens and closes in a sash frame) is attached.

[0005] The above-mentioned exterior materials include ceramic-based (including cement-based) and metal-based materials. In the above-mentioned siding factory outfitting, for example, wood chips, wood fibers, pulp, etc. As a cement plate (or a plate made of a hardened material other than cement) that can be joined by nailing, for example, hard wood chip cement is used, and the trunk is joined to a wooden wall panel by nailing. The siding was joined to the torso by nailing. Also,
At least a part of the body edge is joined to a core material arranged in a wood panel serving as a wall panel, and the siding is joined to the wood panel through the body edge, so that the siding is reliably carried out in the wood panel. In order to separate the siding and the wall panel by interposing the torso between the siding and the wall panel, and to secure the air permeability of the wood panel as the wall panel, What is used.

[0006]

By the way, the above-mentioned body edge is a thin plate-shaped wood which has a predetermined thickness and has been subjected to a treatment for improving durability. It has become difficult. Thus, for example, it is conceivable to join the exterior material to the wall using a joining hardware instead of the nail joining using the trunk edge. In other words, by attaching the metal pieces that hang on each other to the wall and the exterior material, and by hooking the metal pieces together, by joining the wall and the exterior material, the wall and the exterior material can be used without using the rim. Can be joined in a separated state.

Here, when the ceramic exterior material is joined to the wall with the above hardware, there is a problem that the metal cannot be easily joined to the exterior material because the materials are different. . That is, since the metal and the exterior material have different coefficients of thermal expansion, a difference occurs in the thermal expansion between the metal and the exterior material, causing a difference in the joint between the exterior material and the hardware.

[0008] In addition, when the above hardware is bonded to the exterior material, it takes some time until the adhesive cures and the adhesive strength is developed. It is necessary to take measures to prevent
For example, if a recess or a groove is formed in a portion of the exterior material to which the metal is joined, and the metal is fitted in the recess or the groove, the metal is prevented from moving while the adhesive is hardened. be able to. However, in this case, since the conventional exterior material fixed to the wall body by nailing as described above does not have a concave portion or a groove on the back surface, it is necessary to newly manufacture an exterior material for a joint metal. However, in this case, a new mold has to be produced, and it is costly to recreate all the molds for a plurality of exterior materials having different patterns.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a mounting structure for an exterior material that can easily attach the joining hardware to the exterior material when attaching the exterior material to the wall using the joining hardware. The purpose is to provide.

[0010]

According to a first aspect of the present invention, there is provided a mounting structure for an exterior material, as shown in FIGS. 1 to 8, for example, a wall (large connecting panel 2) serving as an outer wall of a building. Is a mounting structure of an exterior material for attaching a plate-shaped exterior material 1 to an outer surface of a first locking member 10 attached to an outer surface of the wall 2 and a back surface of the exterior material 1. A second locking member 20 is provided. By engaging the first locking member 10 and the second locking member 20, the wall 2 and the exterior material 1 are separated from each other. The exterior material 1 is attached to the wall body 2, the second locking member 20 is bonded to the back surface of the exterior material 1 by a bonding material, and is bonded to the exterior material 1 of the second locking member 20. A convex portion 23 slightly protruding from the joining surface is formed on the joining surface to be formed.

According to the above configuration, when the joining surface of the second locking member 20 is pressed against the back surface of the exterior material 1 so as to be joined to the back surface, the joining surface of the second locking member 20 and the exterior material 1 are joined. A gap is formed between the back surface and the projections 23 formed on the bonding surface. And even if the back surface of the exterior material 1 and the joining surface of the second locking member 20 are pressed against each other, a gap is generated between them, so that an adhesive such as an adhesive,
When a well-known bonding material (cured material such as various resins and cements) that generates a bonding force by hardening is sufficiently used, a thick bonding material between the exterior material 1 and the second locking member 20 is used. A layer will be formed.

Therefore, a thick layer of the joining material is formed between the exterior material 1 having a different coefficient of thermal expansion and the second locking member 20, so that the joining material functions as a cushioning material, and The displacement of the amount of deformation between the first and second locking members 20 due to heat can be absorbed by the bonding material. In this case,
It is necessary to use, for example, a bonding material that elastically deforms in a hardened state or a material whose coefficient of thermal expansion is intermediate between the exterior material 1 and the second locking member 20. In addition, the convex portion 23 provided on the joint surface of the second locking member 20 is buried in the bonding material, and has a function of increasing the bonding force (pull-out stress) between the exterior material 1 and the second locking member 20. Will do. In addition, the convex portion 23 can also function as a reinforcing rib for increasing the strength of the second locking member 20.

According to a second aspect of the present invention, there is provided the exterior member mounting structure according to the first aspect, wherein the exterior member 1 and the second locking member 20 are joined to each other. In addition, both an adhesive having elasticity in a cured state and a joining member (screw 22b) driven into an exterior material such as a screw are used.

According to the above configuration, since the adhesive having elasticity in the cured state is used, the thermal expansion coefficient differs between the exterior material 1 and the second hook member 20, and the exterior material 1 and the second Due to the difference in the amount of deformation between the second locking member 20 and the second locking member 20, the displacement generated at the joint between the exterior material 1 and the second locking member 20 can be absorbed by the elastic deformation of the adhesive. In addition, the adhesive and the screw 22b are used in combination, and the second locking member 20 is temporarily fixed to the exterior material 1 with the screw 22b until the adhesive force of the adhesive is developed. There is no need to provide a structure that holds the second locking member 20 in the mounting position until the agent cures.

Accordingly, grooves, recesses, ridges, projections, etc., for positioning and holding metal parts and the like used for joining on the back surface, such as the exterior material 1 conventionally joined to the wall body 2 by nailing, etc. Can be used as it is as the exterior material 1 for the present invention, and an increase in the manufacturing cost of the exterior material 1 can be prevented. Further, as in the case of the configuration according to claim 1, the exterior material 1 is formed by the projections 23.
A thick adhesive layer can be formed between the back surface of the first member and the joint surface with the second locking member 20, so that the adhesive has a thickness capable of being sufficiently elastically deformed, and Stop member 2
The difference in deformation due to heat with zero can be absorbed.

As the adhesive, a well-known elastic adhesive can be used. Further, the joining member 22b is
Any material such as a screw 22b or a nail that is driven into the exterior material 1 may be used. It should be noted that, for a wood screw-like material such as a screw, even if it is driven, it does not necessarily mean that it is driven by hitting it. included.

According to a third aspect of the present invention, there is provided an exterior material mounting structure for mounting a plate-shaped exterior material 1 on an outer surface of a wall (large connecting panel 2) serving as an outer wall of a building. And a first locking member 10 attached to the outer surface of the wall 2 and a second locking member 20 attached to the back surface of the exterior material 1. The exterior material 1 is attached to the wall body 2 in a state where the wall body 2 and the exterior material 1 are separated from each other by engaging the second engagement member 20, and the second engagement The member 20 is characterized in that it is joined to the back surface of the exterior material 1 by an adhesive having elasticity in a cured state and a joining member (screw 22b) driven into the exterior material 1 such as a screw.

According to the above configuration, since the adhesive having elasticity in the cured state is used, the thermal expansion coefficient differs between the exterior material 1 and the second hooking member 20, and the exterior material 1 and the second Due to the difference in the amount of deformation between the second locking member 20 and the second locking member 20, the displacement generated at the joint between the exterior material 1 and the second locking member 20 can be absorbed by the elastic deformation of the adhesive. In addition, the adhesive and the screw 22b are used in combination, and the second locking member 20 is temporarily fixed to the exterior material 1 with the screw 22b until the adhesive force of the adhesive is developed. There is no need to provide a structure that holds the second locking member 20 in the mounting position until the agent cures.

Accordingly, grooves, recesses, ridges, protrusions, etc., for positioning and holding metal parts and the like used for bonding on the back surface, such as the exterior material 1 conventionally bonded to the wall body 2 by nailing, etc. Can be used as it is as the exterior material 1 for the present invention, and an increase in the manufacturing cost of the exterior material 1 can be prevented. In addition, the same thing as the structure of Claim 2 can be used for the joining member 22b and the adhesive.

According to a fourth aspect of the present invention, there is provided the exterior material mounting structure according to the third aspect, wherein the exterior surface of the exterior material 1 is joined to the second locking member 20;
A protrusion 23 slightly protruding from the joining surface is formed on at least one of the joining surfaces of the second locking member 20 and the joining surface joined to the exterior material 1.

According to the above configuration, the second locking member 20
When the second locking member 20 and the exterior material 1 are joined by a joining member 22b such as a screw in a state where an adhesive layer is formed by an adhesive between the second engagement member and the exterior material 1, When the second locking member 20 and the exterior material 1 are joined by the joining member, the second engagement member 20 is attached to the exterior material 1 because the projection 23 is formed on the adhesive surface of the exterior material 1 or 20. Even when pressed, the convex portion 23 functions as a spacer, and the distance between the bonding surface of the second locking member 20 and the bonding surface of the exterior material 1 is increased by the convex portion 2.
3 is secured corresponding to the amount of protrusion, and a state in which the adhesive layer is formed thicker in portions other than the protrusions 23 can be provided.

That is, when there is no convex portion 23,
By joining the second locking member 20 and the exterior material 1 using the joining member 22b such as a screw, the second locking member 20 is pressed against the exterior material 1 and the second locking member 20 and the exterior material 1 are pressed. 1
Is in a crushed state, and only a thin adhesive layer can be formed between the second locking member 20 and the exterior material 1. However, if the convex portion 23 exists, the bonding member Even when the second locking member 20 is pressed against the exterior material 1 by the bonding of 22b, a gap corresponding to the convex portion 23 is secured between the bonding surface of the second locking member 20 and the bonding surface of the exterior material 1. Thus, the adhesive layer is formed thick without being crushed.

On the other hand, when the amount of deformation of the exterior material 1 and the second locking member 20 due to the temperature change is different as described above, even if the adhesive is hardened and elastic,
If the thickness of the adhesive layer formed of the cured adhesive formed between the second adhesive member and the second locking member 20 is small, the adhesive layer cannot be sufficiently elastically deformed, and a large adhesive force can be secured. Can not. Therefore, by forming the convex portion 23 as described above, the exterior material 1 and the second locking member 20 are joined by the joining member 22b such as a screw, and the second locking member 20 is pressed against the exterior material 1. Even in the configuration, a gap corresponding to the convex portion 23 is maintained between the exterior material 1 and the second locking member 20, and a thick adhesive layer is secured between the exterior material 1 and the second locking member 20. Therefore, the exterior materials 1 having different coefficients of thermal expansion and the second locking member 20 can be firmly joined.

Further, since the thickness of the adhesive layer corresponds to the amount of protrusion of the convex portion 23, it is possible to change the thickness of the adhesive layer by changing the amount of protrusion of the convex portion 23. By optimizing the amount of protrusion of the projection 23, it is possible to form an adhesive layer having a thickness capable of obtaining a strong adhesive force. In addition, in order to make the distance between the second locking member 20 and the exterior material 1 uniform, a plurality of the same protrusion amount may be provided at intervals on the bonding surface of the second locking member 20 or the exterior material 1. Convex part 2
3 is preferably formed.

According to a fifth aspect of the present invention, in the mounting structure for an exterior material according to the second or fourth aspect, the second locking member 20 is provided on the back surface of the exterior material 1 with the adhesive. And the fixing part 2 fixed by the joining member 22b
2 and an engaging portion (engaging piece 21) that engages with the first locking member 10, and the exterior surface of the fixing portion 22 that is adhered to the exterior material 1 has the exterior material 1. The projection 23 is formed to be slightly convex toward.

The second locking member 20 includes the exterior material 1 on the wall 2.
Is attached, the load of the exterior material 1 is applied. Therefore, the second locking member 20 needs to have a strength to withstand the above-mentioned load. At this time, the thickness of the second locking member 20 is reduced. As a method of increasing the strength without increasing the thickness, it is conceivable to provide a reinforcing rib on the fixing portion 22 of the second locking member 20, but if the convex portion 23 functions as a reinforcing rib, the convex portion may be provided. 23 is the same improvement in joint strength as in the case of the above-described claim 4 and the second locking member 20.
It can perform two functions at once, with its own strength enhancement. That is, the second locking member 20 having the fixing portion 22 having the convex portion 23 has high strength and is firmly joined to the exterior material 1. For example, the second locking member 20 is reduced in weight. Since the outer member 1 can also be sufficiently supported, the cost and weight of the second locking member 20 can be reduced.

According to a sixth aspect of the present invention, there is provided an outer wall material mounting structure according to the fifth aspect, wherein the fixing portion 22 is driven into the outer material 1 such as a screw. A through-hole (screw hole 22a) through which the joining member (screw 22b) to be inserted penetrates is formed, and at least one of the left, right, and right directions above and slightly away from the through-hole 22a. The convex portion 23 is provided on the side.

According to the above configuration, the through hole 2 of the fixing portion 22
2a, that is, at a position slightly away from
Is formed, even if the fixing portion 22 is slightly deformed by the fixing member 22 being pressed against the exterior material 1 by the joining member 22b penetrating through the through hole 22a, the joining member 2
At the joint position 2b, it is possible to prevent the fixing portion 22 and the exterior material 1 from being substantially in contact with each other. In other words, when the projection 23 and the joining position of the joining member 22b are far apart, the fixing portion 22 is slightly deformed by the fixing member 22 being pressed against the exterior material 1 by the joining member 22b. At the position of the joining member 222b, the fixing portion 22 and the exterior material 1 are almost in contact with each other.

Further, when the joining position by the joining member 22b, that is, the position of the through hole 22a and the position of the convex portion 23 are not separated at all (the state where they are adjacent to each other), the joining member 22b, in particular, screws When the joining member 22b having a screw-like screw is driven into the exterior material 1,
Scrap from the exterior material 1 may be caught between the convex portion 23 and the exterior material 1, and the distance between the fixing portion 22 and the exterior material 1 may be larger than an appropriate interval corresponding to the projection amount of the convex portion 23. There is. However, the through hole 2 through which the joining member 22b penetrates
By slightly separating the position of the protrusion 23 from the position 2a and arranging the protrusion 23 on the left or right of or above the through hole 22a, that is, by not arranging the protrusion 23 directly below the through hole 22a, It is possible to prevent debris generated when the joining member 22b is joined between the convex portion 23 and the exterior material 1 from being pinched, and to ensure an appropriate distance between the fixing portion 22 and the exterior material 1. it can. In addition, by providing an interval between the exterior material 1 and the second locking member 20 by the convex portion 23, the above-mentioned dust falls without being sandwiched between the exterior material 1 and the second locking member 20 as described above. According to the present invention, quality can be homogenized.

According to a seventh aspect of the present invention, in the mounting structure for an exterior material according to the fifth or sixth aspect, the fixing portion 22 is a strip-shaped plate extending left and right. A plurality of engaging portions 2 are spaced apart from each other on the fixed portion 22.
A plurality of through-holes 22a are formed in a row in the upper and lower rows at positions corresponding to the engaging sections 21 of the fixing section 22, and the through-holes 22a are formed on the left and right of the row of the through-holes 22a, respectively. The projection 23 is formed along the row direction of the holes 22a.

According to the above configuration, the same operation and effect as those of the fifth aspect can be obtained, and the second locking member 20 to which the load of the exterior material 1 is applied as described above can reduce the load of the exterior material 1. In the case where a test in which a considerably large load is applied is performed, a portion where deformation or the like is likely to occur, here, the fixing portion 2
And a projection 23 functioning as a reinforcing rib around a portion where the second engagement portion 21 is provided and the through hole 22a is provided.
Is formed, so that the protrusion 23 is more efficient and
The strength of the second locking member 20 can be reliably increased.
In addition, since the shape of the second locking member 20 has a plurality of engaging portions 21, only one engaging portion 21 is provided by attaching one second locking member 20 to the exterior material 1. This is the same state as when a plurality of second locking members 20 are attached, and the work of attaching the second locking members 20 to the exterior material 1 can be saved.

Further, by forming the second locking member 20 to have a plurality of engaging portions 21, the area of the fixing portion 22 is increased as compared with the case where one engaging portion 21 is provided. Accordingly, the bonding surface with the exterior material 1 is widened, and the bonding strength to the exterior material 1 can be increased. In addition, by attaching one second locking member 20 to the exterior material 1, a plurality of engagement portions Since the mounting member 21 can be attached to the exterior material 1, labor for attaching the second locking member 20 can be reduced.

As shown in FIGS. 4 to 7, the second locking member 20 includes a fixing portion 22 fixed to the back surface of the exterior material 1,
An engaging piece 21 extending downward from the fixing portion 22 is provided. The fixed part 22 is a band-shaped plate body whose left-right width is slightly shorter than the left-right width (１ ／ plane module) of the exterior material 1. A pair of upper and lower screw holes 22a are formed at the left and right ends and the center of the fixed portion 22, respectively. The fixing portion 22 is screwed to the exterior material 1 with a screw 22b penetrating the screw hole 22a, and is adhered to the exterior material 1 with an adhesive. Note that the left and right positions of the screw holes 22a formed in the fixed portion 22 and the left and right positions of the engagement pieces 21 formed in the fixed portion 22 substantially match.

The second locking member 20 is basically bonded to the exterior material 1 with an adhesive.
The second locking member 20 is temporarily attached to the exterior material 1 by a screw 22b until a sufficient bonding force is developed when the second locking member 20 is bonded to the exterior member 1. In this way, by using the screw 22b and the adhesive together, the second locking member 20 can be easily attached to the exterior material 1.

That is, the second locking member 20 is
b, the recesses, protrusions, ridges, grooves, etc., which can regulate the position of the second locking member 20 until the adhesive develops a sufficient adhesive force, are formed on the back surface of the exterior material 1. Even if the second locking member 20 is not formed, the second locking member 20 can be held at a predetermined position until the adhesive develops a sufficient adhesive force. Therefore, even if the exterior material 1 is attached to the wall with a joint metal or the like, there is no need to prepare a special exterior material 1. For example, the exterior material 1 joined by nails or the like can be used as it is in this example of the exterior material. It can be used for a mounting structure, and cost can be reduced.

The second locking member 20 is basically made of a metal plate such as a steel plate, and the exterior material 1 is of a ceramic type. The coefficients of thermal expansion are different. Therefore, as the adhesive, a well-known elastic and elastically deformable material can be used to absorb the difference in the amount of deformation between the exterior material 1 and the second locking member 20 due to heat. Must be used.

The fixing portion 22 is provided with convex portions 23 projecting toward the exterior material 1 on an adhesive surface adhered to the exterior material 1. The convex portions 23 are formed when the second locking member 20 which is a metal plate is pressed and molded, and are formed as long ridges vertically. It is to be noted that the convex portions 23 of the fixing portion 22 are not formed by pressing, but the fixing portion 22 is made thicker only at the convex portion 23, or the convex portion 23 is joined to the fixing portion 22. However, the cost is higher than when forming by pressing.

The convex portions 23 are arranged in pairs on the left and right ends and the center of the fixed portion 22, respectively, ie, on the left and right of the screw holes 22a, 22a (through holes) formed in a line in the vertical direction. It is formed slightly apart from 22a. Also, the projections 23 are arranged in a row of upper and lower screw holes 22.
The screw holes 22a are formed vertically long along the upper and lower rows of the screw holes 22a on the left and right sides of 22a. Also, the protrusions 23 ...

The amount of protrusion of the protrusions 23, that is, the distance from the joint surface of the fixing portion 22 to the position farthest from the joint surface of the protrusion 23 (the distance in the direction perpendicular to the joint surface) is
It is about 1 mm. The protrusion amount of the convex portions 23 is determined so that the adhesive layer formed between the fixing portion 22 and the exterior material 1 has an appropriate thickness, and is 1 mm.
It is not limited to before and after.

The convex portions 23 function as reinforcing ribs, and increase the strength of the fixing portion 22 of the second locking member 20 to which the load of the exterior material 1 is applied. In particular, the second locking member 2 engaged with the first locking member 10

An interval corresponding to the amount of protrusion of the portions 23 can be secured. Then, the fixing portion 2 with the adhesive applied thereto
When 2 is screwed to the exterior material 1, the adhesive is filled in the gap secured as described above, so that an adhesive layer made of an adhesive having the same thickness as the gap can be secured. .

Since the thickness of the adhesive layer made of the adhesive having elasticity in the cured state is thick, the thickness is sufficient when the amount of deformation between the exterior material 1 and the fixing portion 22 due to the temperature change is different. When the adhesive layer is elastically deformed and absorbs the difference in the amount of deformation between the exterior material 1 and the fixing portion 22, when the exterior material 1 and the fixing portion 22 thermally expand or contract, the expansion amount and the contraction amount are large. Even if there is a difference, the exterior material 1 and the fixing portion 22

May be larger than the protrusion amount of the screw hole 22a as described above.
Since it is formed at a slight interval from, waste is not trapped between the convex portion 23 and the exterior material 1. If the screw 22b and the convex portion 23 are too far apart, even if the fixing portion 22 is slightly deformed, the fixing portion 22 and the exterior material 1 are almost in contact with each other at the screw 22b. Therefore, the position of the convex portion 23 is
The screw hole 22a is located at a portion other than below the screw hole 22a.
It is preferable that they are slightly adjacent to each other without being adjacent to a.

The engaging piece 21 is connected to the first locking member 10.

In a state where the engagement piece 21 is loosely screwed to the large connecting panel 2, the screw hole 21 is formed so that the position of the engagement piece 21 can be finely adjusted.
a and 21a are long holes that are long on the left and right.

The second locking member 20 is used not only as a member to be engaged with the first locking member 10 but also as a fixing member for fixing the exterior material 1 to the large connecting panel 3. That is, since the first locking member 10 and the second locking member 20 are formed so as to be movable left and right, the exterior material 1 is attached to the large connecting panel 3 so as to be movable left and right. Is fixed by a fixing member including the second locking member 20.

Then, on the upper edge of the exterior material 1, a second locking member 20 as a fixing member is placed upside down and attached to another portion.

According to the mounting structure of the exterior material according to the first aspect of the present invention, even if the back surface of the exterior material and the joining surface of the second locking member are pressed against each other, a gap is generated therebetween.
When an adhesive or other well-known joining material (cured material such as various resins and cements) that generates a joining force by curing is sufficiently used as the above-mentioned joining material, the outer material and the second locking member may be connected to each other. A thick layer of bonding material will be formed between them. Therefore, since a thick layer of the joining material is formed between the exterior material having a different coefficient of thermal expansion and the second locking member, the bonding material functions as a cushioning material, and the exterior material and the second locking member are used. The displacement of the deformation amount due to heat with the member can be absorbed by the bonding material. In addition, the protrusion provided on the joint surface of the second locking member is buried in the bonding material, and functions to increase the bonding force between the exterior material and the second locking member. Further, the convex portion can also function as a reinforcing rib for increasing the strength of the second locking member.

According to the mounting structure of the exterior material according to the second aspect of the present invention, since the adhesive having elasticity in a cured state is used, the thermal expansion coefficient differs between the exterior material and the second hook member. ,
Due to the difference in the amount of deformation between the exterior material and the second locking member due to the temperature change, the displacement generated at the joint between the exterior material and the second locking member can be absorbed by the adhesive being elastically deformed.
In addition, by using together with the adhesive, the second locking member is temporarily fixed to the exterior material with a screw until the adhesive strength of the adhesive is developed, so that the exterior material is cured until the adhesive is cured. There is no need to provide a structure that holds the two locking members in the mounting position. Therefore, there is no groove, a concave portion, a ridge, a convex portion, or the like, for positioning and holding a metal piece or the like used for bonding, such as an exterior material that has been conventionally bonded to a wall body by nailing. The exterior material can be used as it is as the exterior material for the present invention, and an increase in the manufacturing cost of the exterior material can be prevented.

According to the mounting structure of the exterior material according to the third aspect of the present invention, the second locking member is temporarily fixed to the exterior material with a screw until the adhesive force of the adhesive is developed. There is no need to provide a structure that keeps the second locking member in the mounting position until the adhesive is cured,
An exterior material that is not provided with a groove, a concave portion, a ridge, a convex portion, or the like for positioning and holding a metal piece or the like used for bonding on the back surface can be used as it is as an exterior material for the present invention, and the manufacturing cost of the exterior material Can be prevented from increasing.

According to the mounting structure of the exterior material according to the fourth aspect of the present invention, by joining the exterior material and the second locking member with a bonding member such as a screw, the second locking member is attached to the exterior material. As a configuration to be pressed, a gap corresponding to the convex portion is maintained between the exterior material and the second locking member, and a thick adhesive layer can be secured between the exterior material and the second locking member. In addition, the exterior members having different coefficients of thermal expansion and the second locking member can be firmly joined. In addition, since the thickness of the adhesive layer corresponds to the amount of protrusion of the convex portion, it is possible to change the thickness of the adhesive layer by changing the amount of protrusion of the convex portion. By optimizing the amount, an adhesive layer having a thickness capable of obtaining a strong adhesive force can be formed.

According to the mounting structure of the exterior material according to the fifth aspect of the present invention, the convex portion has two functions of improving the joining strength and improving the strength of the second locking member itself as the reinforcing rib once. Can be fulfilled. That is, the second locking member having the fixing portion having the convex portion has high strength and is firmly joined to the exterior material, and can sufficiently support the exterior material.

According to the outer wall material mounting structure of the sixth aspect of the present invention, the convex portion is formed at a position slightly apart from the through hole for penetrating the joining member of the fixed portion, that is, near the through hole. Therefore, even if the fixing portion is slightly deformed by the fixing member being pressed against the exterior material by the joining member, the fixing portion and the exterior material almost abut on the joining position of the joining member. The state can be prevented. In addition, in a state where the joining position by the joining member, that is, the position of the through hole and the position of the projection are not separated at all, the joining member, particularly, the joining member having a screw-shaped screw such as a screw is used for the exterior material. When driving in, there is a possibility that debris from the exterior material is caught between the protrusion and the exterior material, and the distance between the fixed part and the exterior material becomes larger than the appropriate distance corresponding to the protrusion amount of the projection. However, while the position of the convex portion is separated from the position of the through hole through which the joining member penetrates, and is disposed on the left, right, or above the through hole of the convex portion, that is, the convex portion is not disposed immediately below the through hole. It is possible to prevent the waste generated at the time of joining the joining member from being caught between the outer member and the outer member, and to ensure an appropriate distance between the fixing portion and the outer member.

According to the exterior member mounting structure of the present invention, an excessively large load is applied to the second locking member to which the external member load is applied as described above. When a test is performed, a convex portion that functions as a reinforcing rib is formed around a portion where deformation or the like is likely to occur, here, an engaging portion of the fixing portion is provided and a portion around which the through hole is provided. The strength of the second locking member can be efficiently and reliably increased by the convex portion.
