[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building exterior material and an exterior structure of a building used for a building in which peaks and valleys are alternately formed in a construction state.

[0002]

2. Description of the Related Art Conventionally, as an exterior material used for a building in which peaks and valleys are alternately formed in a construction state,
There are exterior materials called folded plates and tile sticks. In recent years, from the viewpoint of the shortage of construction workers and the improvement of the working environment, the connection type of the exterior material is changing from a bolt-tightening type or a goby-tightening type to a fitting type, which is easy to work. In the fitting type,
Although there is a type in which a suspender is fitted to a goby portion from above, a proposal shown in Japanese Patent Application Laid-Open No. 6-322901 has been made as an exterior material that at least connects the exterior materials by elastic fitting. In the outer enclosure described in this proposal, in the connected state, an outer gore and an inner gore are provided at an edge located substantially at the center of the mountain, and an engaging portion is formed on each of the outer gore and the inner goby, It is a configuration in which the outer goby is engaged with the goby from the vertical direction.

[0003]

However, in the outer enclosure having the above-described structure, a predetermined position is required at a position where a member such as a tight frame or a suspension member that can reliably regulate the position of the outer enclosure exists inside the outer enclosure. Elastic fitting can be performed and connection can be made, but in places where there is no tight frame such as a purlin or beam, the outside goby pressed from above does not elastically fit and pushes down the inner goby, so connection work is extremely difficult There has been a problem that it becomes difficult or the connection itself becomes impossible (in other forms, it tilts inward). In addition, since a tight frame or the like is usually installed at intervals of 3 to 5 m, the above-described poor construction is likely to occur. However, the thickness of the material of the enclosure is normally 0.6 to
By making it thinner than 1.2 mm or making the fitting relationship looser, it is possible to perform the above-mentioned elastic fitting, but such means directly reduces the strength of the exterior material and the exterior structure. Therefore, it is not practical at all as a technical solution.

The exterior material 1 is not particularly limited in its material, but typically has a surface decorative steel sheet, a laminated steel sheet, a plated steel sheet, a stainless steel sheet, an aluminum alloy sheet having a thickness of about 0.4 to 1.6 mm. A known metal material such as a titanium alloy plate or a copper plate is formed into a predetermined shape by roll forming or other means. It is to be noted that a similar shape can be formed by using a hard resin plate, a carbon fiber laminate plate, or the like, and that all of them can be constructed with them, or can be constructed in combination with the above-mentioned metal material. Also, on the back surface of the exterior material 1,
For reasons of dew condensation prevention, soundproofing, and fireproofing measures, a backing material such as polyethylene foam or glass wool sheet may be added as necessary. Exterior material 1 shown in FIGS.
More specifically, this is a folded plate roofing plate having inclined surface portions 5 and 5 between the substantially flat face plate portion 2 and the goby portions 3 and 4 at the edge thereof. In addition, the outer goby portion 3 is a lower end and an inner side (the face plate portion 2) of the outer portion of the substantially umbrella-shaped cover portion 33 that is directed downward and to the left and right.
The lower end of each side is bent symmetrically to the cover portion 33 side. The inner surface above the bent portion on the outer side is the fitting portion 31 and is located on the inner side (face plate portion 2).
The inner surface of the concave portion formed by the lower half of the cover portion 33 (on the side) and above the bent portion in the shape of a letter is the contacted portion 32. On the other hand, the inner goby portion 4 is bent so as to expand the lower end on the outer side and the lower end on the inner side of the centrally asymmetrical ridge-shaped engaging portion 43 so as to expand outward and downward, respectively. In this configuration, the lower end of the expanded portion of the face plate portion 2) is bent in a V-shape toward the ridge-shaped engagement portion 43. The distal end of the outwardly expanding portion is the contact portion 41, and the upper outer surface of the bent portion on the inward side (the side of the face plate portion 2) is the fitted portion 42. In addition, the outwardly expanding portion where the abutting portion 41 is formed is formed in a single-piece state so as to jump up as compared with the position in the assembled state.

The exterior material holding member 7, which constructs the exterior structure shown in FIG. 2 together with the exterior material 1, basically includes at least a holding portion 741 elastically fitted to the inner surface of the fitted portion 42 of the inner goby portion 4. This is a member known as a conventionally known suspender or tight frame, and includes a combination product of a plurality of members. The exterior material holding member 7 includes the exterior material 1
Depending on the size and required strength, it is usually formed by pressing a stainless steel plate or plated steel plate having a thickness of about 0.6 to 3.2 mm. The exterior material holding member 7 used in the exterior structure of FIG. 2 is formed by bending a relatively thick short width material, and is provided at the left and right ends of a horizontal piece 71 that is substantially horizontal and has a slightly inclined right and left downward.
Outward and downward leg pieces 72, 72 are formed, and furthermore, at the lower ends thereof, outwardly substantially fixed pieces 73, 73 are formed, and the horizontal piece 71 has a star (*) upper half shape. This is a configuration in which the support pieces 74 are attached in an upright manner. This support piece 7
The upper edge shape of 4 substantially matches the cross-sectional shape of the inner goby portion 4 in the assembled state. The lower edge of the projection on one side (the left side in the drawing) of the support piece 74 has a retaining portion 74 that elastically engages with the inner surface of the fitted portion 42 of the inner goby portion 4.
1, a projection on the other side (the right side in the drawing) of the support piece 74 is an outer holding section 742 that elastically fits with the abutted portion 32 of the outer gob 3, and is substantially at the center of the support piece 74. A protrusion upward from the second holding portion 743 that engages with the ridge-shaped engaging portion 43 of the inner goby portion 4.

The exterior base material 6 for fixing the exterior material holding member 7 is generally a steel frame such as a beam, a purlin, or a rim, but is not limited to this. For example, a configuration in which a base material such as a wool cement board, a wood chip cement board, a lightweight cellular concrete board or the like may be laid on the steel frame body, or a configuration in which a steel frame or wood hut is laid on a concrete frame, The exterior material holding member 7 may be directly attached to the concrete surface whose foundation has been adjusted. Therefore, the exterior base material 6 to be applied in the present invention is provided with the exterior material holding member 7 by fixing means such as nails, screws, anchors, and welding.
Refers to all building frames that can be attached, and includes boards such as wood wool cement boards to be laid on the frame as required.

The construction of the exterior structure of the present invention is generally performed in the following procedure. An exterior material holding member 7 such as a tight frame is mounted on a steel frame base 6 such as a beam, a purlin, or a rim, and the exterior material 1 is elastically fitted thereto. The construction of the exterior structure of FIG. 2 is similar, but will be described in detail below with reference to FIGS. FIG. 3 shows a construction state at a location where the exterior material holding member 7 exists, and FIG. 4 shows a construction situation at a location where the exterior material holding member 7 does not exist. .

First, as shown in FIG. 3 (a), the exterior material holding member 7 having the above-described structure is previously mounted on the exterior base material 6, and one side of the exterior material holding member 7 (the left side in the drawing). Side), the inner goby portion 4 of the exterior material 1 is exposed from the
2 and the holding portion 741 of the exterior material holding member 7 are elastically fitted and held. At this time, the expanded portion on the inner side (face plate portion 2 side) of the inner goby portion 4 covers the upper edge of the support piece 74 closely, and the inner surface of the ridge engagement portion 43 is in contact with the second holding portion 743. Engage. As described above, the inner goby portion 3 is held by the exterior material holding member 7 at two places (the inner surface of the fitted portion 42 and the inner surface of the ridge-shaped engaging portion 43). Thereafter, the exterior material holding member 7
From outside (the right side in the drawing). Exterior material holding member 7 during this construction situation
FIG. 4A shows a state where no symbol exists.

Next, as shown in FIG. 3 (b), the outer goose portion 3 of the right side exterior material 1 from the upper right side to the lower left side is shown in FIG. As shown in the drawing, the sliding portion 41 is positioned so that the contact portion 41 of the inner goby portion 4 contacts the contact portion 32 of the outer goby portion 3. At this time, the expanded portion where the contact portion 41 on the outer side of the inner goby portion 4 is formed is, as described above, in a single product state, formed so as to have a raised shape as compared with the position in the assembled state. When the cover portion 33 of the outer goby portion 3 is pressed as shown in FIG. 3C in this state, the contact portion 32 presses the contact portion 41. Then, the outer expanded portion is brought into contact with the upper edge of the support piece 74 and is elastically fitted with the outer holding portion 742 of the exterior material holding member 7. FIG.
As shown in (b) and (c), even at a position where the exterior material holding member 7 (support piece 74) does not exist, the elasticity of the expanded portion on the outer side of the inner goby portion 4 causes the contact portion 41 to be in contact with the contact portion 41. Contact part 3
The contact with 2 is assured. At the time of FIG. 3 (c), the lower end of the fitting portion 31 of the outer goby portion 3 presses the expanded portion from the state in which the lower end faces the upper surface of the expanded portion of the inner goby portion 4 in a mounted state. While sliding down along its upper surface. Further, when the cover portion 33 of the outer goby portion 3 is pressed, as shown in FIG.
Of the inner goby portion 4 slides downward along the upper surface of the expanded portion. That is, FIGS. 3 (b), (c),
As shown in (d), at the location where the exterior material holding member 7 is present, the inner goby portion 4 is supported by the inner support pieces 74, so that it can be pushed down by the pressing force or tilted inward. Therefore, the lower end of the fitting portion 31 of the outer goby portion 3 slides along the upper surface of the expanded portion of the inner goby portion 4 as described above. In addition, as shown in FIGS. 4B, 4C, and 4D, in a place where the exterior material holding member 7 does not exist,
Since there is no member to support inward, the pressing force pushes down the inner goby portion 4 or causes the inwardly tilting portion to inwardly move. And the positional relationship between the two goby portions 3 and 4 is regulated, so that the inner goby portion 4 maintains its spatial position against the pressing force. Therefore, even in a place where the exterior material holding member 7 does not exist, the outer gob portion 3 is pressed as the cover portion 33 of the outer gob portion 3 is pressed in the same manner as described above.
The lower end of the fitting portion 31 slides along the upper surface of the expanded portion of the inner goby portion 4. As a result, FIGS. 3 (e) and 4
As shown in (e), the fitting portion 31 of the outer goby portion 3 is securely elastically fitted to the fitted portion 42 of the inner goby portion 4 regardless of whether or not the exterior material holding member 7 exists. Become.

Therefore, first, after the exterior material 1 is arranged on one side of the exterior material holding member 7, the exterior material 1 to be arranged on the other side is adjacent to the exterior material 1 with the outer gob portion 3 being lifted slightly upward. It is arranged between the exterior material holding members 7,7. Then, after the position is adjusted so that the contact portion 41 comes into contact with the contacted portion 32, the lifting of the outer goby portion 3 is released, and the connection by the elastic fitting is securely performed only by pressing from above. A peak is formed. After that, by the same construction work, from one side to the other side (from left to right in the drawing)
If the exterior materials 1 are laid in order, an exterior structure in which the hills and the valleys are alternately continuous can be easily constructed.

The exterior structure of FIG. 2 constructed in this manner can reliably prevent the inner gob portion 4 from being pushed down and inwardly tilted by the pressing of the outer gob portion 3 at the time of fitting as described above, so that a reliable Fitting becomes possible. As a result, the fitting / exterior material, such as improvement in workability and labor saving, can surely obtain the function and effect originally intended. In particular, since the contact portion 41 of the inner goose portion 4 is formed in a fluttering shape compared to the position in the assembled state in a single product state, the contact portion 41 and the contacted portion 32 are easily brought into contact with each other. Relationships can be regulated. Further, the fitted portion 42 of the inner goby portion 4 and the contact portion 41
Between them, there is formed a flood prevention space A constituted by the inner surface of the cover portion 33 of the outer goby portion 3, so that the flood prevention space A acts as a decompression space in the event of a storm, and also causes bleeding by capillary action. Since it also acts as a space for preventing rainwater, the function of preventing rainwater from flooding is enhanced. Further, the fitting portion 31 of the outer goby portion 3 is elastically fitted with the fitted portion 42 of the inner goby portion 4, and the inner surface of the fitted portion 42 is formed of the exterior material holding member 7.
The fitting portion 31 is elastically fitted to the holding portion 741 via the fitted portion 42 because the fitting portion 31 is elastically fitted to the holding portion 741. Further, the contacted portion 32 is formed of the exterior material holding member 7.
Are elastically fitted to the outer holding portions 742 of the first pair. Therefore,
Since the outer goby portion 3 is held by the exterior material holding member 7 at two locations, the fitting portion 31 and the abutted portion 32, the anti-negative pressure performance is improved. Since the inner goby portion 4 is located inside the outer gore portion 3, no negative pressure acts. In the inner goby portion 4, the inner surface of the fitted portion 42 is elastically fitted to the holding portion 741, the ridge-shaped engaging portion 43 is engaged with the second holding portion 743, and the exterior material holding member is provided at two places. 7, the positive pressure performance is improved. That is, even when a positive load acts on the face plate portion 2 and the like, and a downward sliding stress acts along the inclined surface portion 5, the sliding is not performed by holding the two places. Note that the outer goby portion 3 is also 2
Since it is held at the location, the anti-positive pressure performance is high. In the exterior structure of FIG. 2, the abutted portion 32 of the outer goby portion 3 is (the outer holding portion 742 of) the exterior material holding member 7.
The fitting portion 4 of the inner goby portion 4 also serves as a
2 (the inner surface) is the exterior material holding member 7 (the holding portion 741)
Since it has a configuration that also has a function of holding (retained), the shape is simpler than a case where a held portion is formed in another part, for example, as in the case of an exterior material 1 used in the exterior structure of FIG. It is excellent in terms of the production formability of the exterior material 1 and the yield of the material.

In the exterior structure shown in FIG. 5, the inner goby portion 4 of the exterior material 1 and the support piece 74 of the exterior material holding member 7 have a symmetrical shape. Instead of not providing the engaging portion 43, an engaging piece 411 bent in a folded shape is extended below the contact portion 41, and the upper edge of the support piece 74 is non-closely covered in a construction state. is there. Further, the support piece 74 is configured such that the lower edge of the projection (outside holding portion 742) on the other side (right side in the drawing) is not used as the third holding portion without providing the center protrusion. The configuration other than the above is the same as the exterior structure of FIG. This exterior structure has exactly the same effects as the exterior structure of FIG. 2, but is superior in terms of the formability of the inner goby portion 4 and the support piece 74 and the yield of the material due to the symmetrical shape. I have. Although the inner goby portion 4 is held by the holding portion 741 of the outer material holding member 7 in the same manner as the outer structure of FIG. 2, the third holding portion on the lower edge of the engagement piece 411 and the outer holding portion 742. With this engagement, the laying stability of the inner goby portion 4 and the positive pressure resistance are improved.

The exterior structure shown in FIGS. 6 and 7 is the same as the exterior structure shown in FIG. 5 except that the shape of the covering portion 33 of the outer goby portion 3 of the exterior material 1 and the shape of the inundation prevention space A are different accordingly. It is almost the same. In this way, the cover portion 33 of the outer goby portion 3 may be formed in any shape in consideration of designability and the like. Note that the exterior material holding member 7 in FIG. 7 has a shape in which there is no protrusion on the other side (the right side in the drawing) of the support piece 74, that is, a structure in which the outer holding portion 742 is not formed.

In the exterior structure shown in FIG. 8, the contact portion 32 of the outer goby portion 3 is convex and the contact portion 41 of the inner goby portion 4 is concave. That is, the configuration (shape) is not particularly limited as long as the abutting portion 41 and the abutted portion 32 abut against each other and regulate the positional relationship between the goby portions 3 and 4.
Any configuration may be used. Further, the abutted portion 32 and the fitted portion 42 do not have the function of being held by the exterior material holding member 7, respectively. That is, the outer held portion 34 elastically fitted to the outer holding portion 742 of the exterior material holding member 7 below the abutted portion 32, and the holding portion 741 of the exterior material holding member 7 below the fitted portion 42. Retained portions 44 to be elastically fitted are formed respectively. However, as is apparent from comparison with the exterior structure of FIG. 2, the exterior structure of FIG. 8 increases the number of bent portions of the exterior material 1, and thus the exterior structure of FIG. It is excellent in terms of moldability and material yield.

In the exterior structure shown in FIG. 9, engaging step portions 721 which are extended and raised from the inclination of the leg pieces 72 on the left and right leg pieces 72, 72 of the exterior material holding member 7, respectively. The engaging step 72 is formed on the inclined surface 5 of the exterior material 1.
The configuration other than the formation of the engaging portion 51 that engages with 1 is the same as the exterior structure of FIG. The exterior structure shown in FIG. 10 has three stepped portions 721 to be engaged formed on the left and right leg pieces 72, 72, respectively.
The configuration is the same as that of the exterior structure of FIG. 2 except that the three engaging portions 51 that engage with the three engaged step portions 721 are formed in the outer structure. In these exterior structures, the exterior material 1
Since the number of holding points for the negative pressure acting on the air bearing is increased, the anti-negative pressure performance and safety are improved. In addition, there is an advantage that these engaging portions 51 can substantially eliminate a pocket wave caused by the material or the molding, and can absorb a molding error due to a change in the material or the thickness.

The exterior material 1 shown in FIG. 11 (a) is a tile rod in which a vertical rising portion 50 is formed in place of the inclined surface portion 5 having the above-described structure, and the exterior structure shown in FIG. Except for the configuration in which the exterior material holding member 7 is made of only a member substantially similar to the support piece 74 having the above configuration, the configuration is the same as that of the exterior structure of FIG. 5, and the effect is the same as that described above.

The exterior structure shown in FIG. 12 is not a complete fitting type, but a partial fitting type structure in which the fixing portion 45 provided on the inner goby portion 4 is fixed to the exterior material holding member 7 by a fixing tool such as a screw. Except for the structure, the same effects as those of the above-mentioned various completely fitting type exterior structures can be obtained. That is, the exterior material 1 of the present invention can be applied to the completely fitted type exterior structure or the partially fitted type exterior structure by using the contact portion 41 provided on the inner goby portion 4 as the outer goose portion. By making contact with the contacted portion 32 provided in 3, the positional relationship between the two goby portions 3, 4 at the time of fitting is regulated, so that the connection by reliable elastic fitting can be performed.

The exterior material 1 used in each of the exterior structures shown in FIGS. 13 and 15 has a contact portion 41 of the inner goby portion 4 which is formed in a single-piece state so as to jump up as compared with the assembled state. Since it is formed to be slightly shorter than that, the secure fitting connection which is the object of the present invention is more secure. However, in the configuration in which the exterior material holding member 7 has the outer holding portion 752, the contact portion 41 A gap is formed between the outer member 752 and the outer holding portion 752, and the gap may hinder the fitting connection at a position where the exterior material holding member 7 is located. Therefore, the auxiliary member 7 described later
7 and the auxiliary means 759, the contact portion 4 of the inner goby portion 4
1 and the outer holding portion 752 of the exterior material holding member 7 are integrated. That is, in the configuration of the embodiment in which the exterior material holding member 7 has the outer holding portion 752 as in each of the exterior structures in FIGS. 13 and 15, the contact is made at a local portion in the roof surface where the exterior material holding member 7 exists. Although the portion 41 and the abutted portion 32 do not directly contact each other, the present invention is reliable when the abutting portion 41 and the outer holding portion 752 are integrated in an assembled state by the auxiliary member 77 or the auxiliary means 759. The outer holding portion 752 is a contact portion 41
Can be considered substantially the same. Then, the outer holding portion 75
Since 2 contacts the contacted portion 32, the contact portion 41 and the contacted portion 32 can be regarded as having a contact relationship after all.

The exterior material holding member 7 used in the exterior structure shown in FIG. 13 is the same as that in FIG. 2 except that a support portion 75 is provided instead of the support piece 74. This support part 7
As shown in FIG. 14, No. 5 is formed by pressing, bending, welding, or the like on a relatively thin plate material, and has a holding portion 751 and an outer holding portion 752 on the left and right sides, and the center (on the axis of symmetry). An upright piece-shaped second holding portion 753 is formed at the bottom. In FIG. 14, reference numeral 754 denotes a through hole for the fixing member 76;
Is a notch for inserting a jig for fastening the fixing tool 76, 756 is a support receiving piece, 757 is a pressed part, 758
Denotes an insertion hole, and the upper side portion of the pressed portion 757 forms the holding portion 751 and the outer holding portion 752.
In addition, the second holding portion 753 is formed by welding pieces bent from left and right in a superposed state. The auxiliary member 77 attached to the support portion 75 has a configuration in which an inclined pressing piece 772 extends at the rear end of the insertion horizontal piece 771, and further, a holding and stabilizing piece 773 extends at the tip of the pressing piece 772. Have been. In this exterior structure, as shown in FIG. 13 (b), after the inner goby portion 4 is elastically fitted to the exterior material holding member 7, it is inserted into the insertion hole 758 of the exterior material holding member 7 from the outside. The member 77 is inserted or press-fitted with a hammer or the like. Auxiliary member 77
Of the contact portion 41 at the position where the exterior material holding member 7 is disposed, presses the contact portion 41 and the outer holding portion 752 in a state of being pressed against the support receiving piece 756.
Can be integrated. In addition, the holding stable piece 773
Presses the base end on the outer side of the ridge-shaped engaging portion 43 to more reliably engage the ridge-shaped engaging portion 43 with the second holding portion 753.

The same exterior material 1 as that shown in FIG. 13 is used in the exterior structure shown in FIG. The support portion 75 of the exterior material holding member 7 used in this exterior structure does not have the insertion hole 758 as shown in FIG.
13 and 14 except that a part of the support receiving piece 756 close to is provided to provide an upright piece-like auxiliary claw piece 759.
The configuration is the same as that in the above. In this exterior structure,
As shown in FIG. 15B, after the inner goby portion 4 is elastically fitted to the exterior material holding member 7, the auxiliary claw piece 759 of the exterior material holding member 7 is tilted down with a hammer or the like in the direction of the arrow. Auxiliary claw piece 7
Reference numeral 59 denotes the contact portion 4 at the position where the exterior material holding member 7 is disposed.
Since the spring of 1 is suppressed, the contact portion 41 and the outer holding portion 752 can be integrated with each other in a state of being pressed against the support receiving piece 756. As described above, even when the auxiliary member having an appropriate configuration is provided in the exterior material holding member 1, the same effect as in the case where the auxiliary member 77 is provided can be obtained.

FIG. 17 shows another shape variation of the exterior material of the present invention. Specifically, the shapes of the outer goose portion 3, the inner goose portion 4, and the contact portion 41 are different. An aspect in which the adhesive material 10 is integrally provided is shown. As the backing material 10, a polyethylene foam (PEF), a fire-resistant glass fiber sheet, or the like can be used. In the case where the contact portion 41 has a large radius of curvature (curvature) as shown in FIGS. Also, FIGS.
When the contact portion 41 has a folded piece (surface) corresponding to the shape of the outer goby portion 3 as shown in (f), the stability with the outer goby portion 3 can be increased. It should be noted that FIGS.
In the embodiment, the materials constituting the exterior material 1 are not in contact with each other, but the backing material 10 attached to the back surface of the exterior material 1 is originally selected according to the specifications of the building and the demands of the customer. This is merely an addition to the material 1, and if this is backed, it is considered to be integral with the exterior material 1, so that it comes into contact in any aspect.

Although the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and may be implemented in any manner unless the structure described in the claims is changed. Can be implemented. For example, in the drawings of the embodiments, known waterproof materials such as asphalt roofing and asphalt felt are not shown, but they do not hinder their use. In the case where a fiber-based heat insulating material or the like is laid on the exterior base, it is preferable that the heat insulating material be stretched from the viewpoint of curing. In addition, the face plate portion of the exterior material of the present invention may be one subjected to soothing wave processing as necessary, or may be one having a rising portion below both goose portions formed in the middle.

[0026]

In summary, the building exterior material of the present invention is
By regulating the positional relationship between the goby parts at the time of fitting, it is possible to reliably prevent the inner goby part from being pushed down or tilted inward by the outer goby part at the time of fitting, which is a weak point of the elastic fitting method, Reliable fitting becomes possible. Also, the inner goby part is 2
Since it is held by the exterior material holding member at the location, the anti-positive pressure performance is improved. In other words, even when a positive load acts on the face plate portion and the like, and a downward sliding stress acts along the inclined surface portion, the sliding is not performed by holding the two places. As a result, the exterior structure of the building according to the present invention can reliably obtain the function and effect originally intended by the fitting type exterior material, such as improvement in workability and labor saving.

Further, if a flood prevention space is formed between the fitted portion and the contact portion of the inner goby portion and the inner surface of the outer fly portion, the flood prevention space acts as a decompression space during a storm. Also, since it acts as a space for preventing seepage due to capillary action, the function of preventing rainwater from infiltrating is enhanced.

Further, when a holding portion elastically fitted to the inner surface of the fitted portion of the inner goby portion is formed on the exterior material holding member,
Since the fitted portion also has the function of being held by the holding portion, the shape is simpler than when the held portion is formed in another portion,
It is excellent in terms of the formability of the exterior material and the yield of the material.

Further, if the outer holding member is formed with an outer holding portion elastically fitted to the abutted portion of the outer goby portion, the holding member against the negative pressure acting on the outer member becomes two places. The anti-negative pressure performance is improved. Further, since the contacted portion also has a function of being held by the outer holding portion, the shape is simpler than in the case where the held portion is formed in another portion, and the production moldability of the exterior material and the yield of the material are reduced. Is excellent.

Further, a ridge-shaped engaging portion is formed on the inner goby portion, and a second holding portion for engaging with the ridge-shaped engaging portion of the inner goby portion is formed on the exterior material holding member, or At the contact portion of the goby portion, an engaging piece bent downward is extended, and a third holding portion elastically fitted with the engaging piece of the inner goby portion is formed at the exterior material holding member. Then, since there are two holding locations for the positive pressure acting on the exterior material, the positive pressure performance is improved.

Further, when the contact portion of the inner goby portion is formed so as to protrude as compared with the position in the assembled state in a single product state, the contact portion and the contacted portion are easily brought into contact to regulate the positional relationship. can do.

When the contact portion of the inner goby portion is prevented from rising by an auxiliary member attached to the external material holding member or an auxiliary means provided on the external material holding member, the contact portion is pressed against the support receiving piece. And the outer holding portion can be integrated, so that reliable fitting connection at the disposition position of the exterior material holding member can be further ensured.

Further, the exterior material is a folded roof plate having an inclined surface portion between the face plate portion and the goby portion, and the stepped portion to be engaged with the engaging portion of the exterior material holding member is provided on the inclined surface portion. When one or more are provided, the number of holding locations for the negative pressure acting on the exterior material increases, so that the negative pressure performance and safety are improved.
