Description

  The present invention is an exterior which takes into consideration not only the penetration of rain water from a screw hole or the penetration of rain water due to capillary action, but also excellent in workability as well as the strength and water tightness under negative pressure action. On the structure.

  The conventional roof called "Yamato-mochi" is a method of mounds in which mountains and valleys continue alternately, and as a method of fixing the roof, as a first method, it will be described later with reference to Figs. 5 (a) and 6 (a). Generally, two methods are used: a method of driving a fixing screw from the side shown in 2.) and a second method of fixing by means of flaps shown in FIGS. 5 (b) and 6 (b). .

However, the problems with the first method include the problem of rainwater infiltration from the screw holes of the fixing screw and the loss of the screw due to strong wind and aged deterioration.
Moreover, as a problem of the said 2nd method, the problem in which rain water infiltrates by the capillary phenomenon by the tightness of an arrow, and an effort by construction by tightening an arrow etc. are mentioned.

  Furthermore, although the first method and the second method will be described in detail in the description of FIG. 5 and FIG. 6 described later, the strength and the water tightness under negative pressure are not considered at all. Met.

  Therefore, the present invention is of course excellent in workability without causing the intrusion of rain water from the screw holes and the intrusion of rain water by capillary phenomenon in the roof structure of "Yamato-dore", and of course also at the time of negative pressure action. An object of the present invention is to provide an exterior structure in which the strength and the water tightness are sufficiently considered.

The present invention has been proposed in view of the above, and on the base, the left and right side edges of the flat plate portion are bent in the same direction, and the tip is further folded back inside to form a side edge formed portion. A valley side exterior plate is used, and by alternately arranging the ridge portion and the valley portion by being alternately arranged, the exterior structure (that is, the downward side edge forming portion of the mountain side exterior plate faces the left and right side edges of the flat portion downward And the upper side edge forming portion of the valley side exterior plate folds the left and right side edges of the flat plate portion upward, and further, the upper end thereof is inward. (A structure having a downward turn-up portion folded back), wherein a backing material having elasticity is attached to the back surface of the flat plate portion of the mountain-side exterior plate, and the backing material is interposed between the valley-side exterior plates adjacent to each other It is pressed against the arranged insulation material, the downward side of the mountain side outer plate An upward folded portion of the forming section, it relates to an exterior structure, characterized in that the engaged downward folded portion of the upward edge forming portion of the valley-side outer plate.
In the following description, the upward turn-back portion of the downward side edge molding portion of the mountain-side exterior plate is referred to as "upper fly", and the downward turn-up portion of the upward side edge molded portion of the valley side exterior plate is referred to as "lower fly". In the illustrated embodiment to be described later, the downward side edge molding portion itself is described as the “upper blind” and the upward molding portion itself as the “lower blind”.

  Further, according to the present invention, in the exterior structure, a holding member having an upright portion having a fixing portion to a base at a lower end thereof and a folded portion where the upper end of the upright portion is folded outward is fixed on the base. An exterior structure is also proposed, characterized in that the downward turnback portion of the upward side edge molding portion of the valley side exterior plate is engaged with the inside of the turnback portion of the holding member.

Since the exterior structure of the present invention adopts the engagement of the upper and lower gobys, it does not cause the penetration of rainwater from the screw holes and the entry of rainwater due to capillary action due to the closure of the gops. In addition, since the construction is such that it is engaged by utilizing the elasticity (repulsive force) of the backing material having elasticity pressed into contact with the heat insulating material , the exterior plates can be attached firmly and stably, and also in the workability. Are better.
Furthermore, when the heat insulating material is disposed on the back surface of the mountain-side exterior plate, it is needless to mention that the heat insulating function is provided, but in particular, the state where the mountain-side exterior plate is mounted on the surface of the heat insulation material. Can be stably disposed on the holding member.

  In addition, when the downward turnback portion of the upward side edge forming portion of the valley side exterior plate is brought into surface contact with and engaged with the upward turnback portion of the downward side edge shaping portion of the mountain side exterior plate, negative pressure is applied. In this case, too, the tip of the upper lip on the mountain-side exterior plate moves deeply deeply upward (with the capillary phenomenon being prevented) while maintaining surface contact and is brought into close contact with the lower lip of the valley-side exterior plate. There is no gap that can occur, blowing can be prevented, and high water tightness can be ensured.

  In addition, when a space opened upward is formed below the engaging portion, this space prevents capillary phenomenon, and the space functions as a drainage path, and any rainwater that has intruded into the drainage path Can flow down.

  Further, when the valley side contact surface further folded inward as the downward turning portion is in surface contact with the mountain side abutting surface further folded inward as the upward turning portion, the capillary phenomenon is caused below the engagement portion. It is easy to form a space sufficient to prevent the movement of the upper fly during the negative pressure action and it becomes easier and more reliable.

  Further, a holding member having a rising portion having a fixing portion to the ground at its lower end and a folded back portion obtained by turning the upper end of the rising portion outward is fixed on the ground, and the upward side edge molding of the valley side exterior plate is formed. When the downward turn-back portion of the part engages with the inside of the turn-back portion of the holding member, the downward turn-back portion is stably regulated, and the upward turn-up portion of the upper exterior plate is It can be stably brought into surface contact and firmly engaged.

In the exterior structure of the present invention, the left and right side edges of the flat plate portion are bent in the same direction on the base, and the tip is further folded back inside to form a side edge formed portion to form a mountain side armor plate and valley side armor plate. In the exterior structure in which the ridge and the valley are continuously formed by arranging, that is, the downward side edge forming portion of the mountain-side exterior plate folds the left and right side edges of the flat portion downward, and the lower end thereof And the upward side edge forming portion of the valley side exterior plate folds up the left and right side edges of the flat plate portion upward and further turns the top side downward inward turning portion. a configuration having, is pressed against the heat-insulating material arranged on the valley side outer plates adjacent the backing laminated material to the left and right causes the additionally provided a backing material having elasticity on the back surface of the flat plate portion of the mountain side outer plate, upward downward side edge forming portion of the mountain side outer plate The return portion, a structure in which engage the downwardly folded part of the upward side edge forming portion of the valley-side outer plate.

An elastic backing material attached to the back of the flat plate portion of the mountain-side exterior plate is pressed against the heat insulating material disposed between the valley-side exterior materials when installing the mountain-side exterior plate, thereby pressing it from above Although the thickness is reduced, by the release of the pressure, a stress that restores the thickness and elastically recovers upward acts.
At that time, first, at the time of pressing from the upper side, the lower side edge-formed portions of the left and right side edges of the mountain-side outer plate spread outwardly in a spreading manner against elasticity.
After that, when the tip of the upward turning portion exceeds the tip of the downward turning portion of the upward side edge forming portion of the valley side armor plate, the downward side edge forming portions of the left and right side edges elastically recover so as to close inward. Therefore, it elastically fits from the outside with respect to the upward side edge of the valley side exterior board.
Such a behavior can be performed substantially similarly even if there is no backing material, due to the elasticity of the metal face material constituting the exterior plate. However, as in the case of the exterior structure of the present invention, by interposing an elastic backing material on the back surface of the mountain-side exterior plate, the mountain-side exterior plate can be lifted upward as a whole even after engagement. Stable engagement is achieved. Further, since the elasticity of the backing material is utilized in this way, the backing material itself is located on the back surface of the mountain-side exterior plate, and is not exposed to the surface side, so the designability is not reduced. Even if the thickness of the paste and the repulsive force are somewhat strong, there is no hindrance to the construction and the appearance.

Thus, the backing material to be attached to the back surface of the mountain-side exterior plate is not particularly limited in its material or function, as long as it has elasticity, but a backing material having various functions such as airtightness By pasting, the following effects can be achieved.
That is, by using a material having elasticity and airtightness as the backing material, even if rainwater or the like from the engaging portion is intruded due to an unexpected cause, the space where the upper side opens as described above is drained. Rainwater can be drained as a passage, but on this drainage passage, the backing material of the mountain-side exterior plate is in contact with the valley-side exterior plate and there is no gap, thereby closing the path through which the wind blows inside. Thus, by closing the wind blow-off path, the wind does not exceed the goose of the valley side exterior plate, and the blowing is prevented.

  In addition, as such a backing material, if it has only elasticity, for example, many foam materials (foamed resin sheet) are commercially available, and therefore it may be used appropriately, and the back having elasticity and airtightness. As a sticking material, a hard urethane foam etc. can be used, for example.

The exterior panel used in the present invention is used for roofing called conventional "Yamato-making", and as described above, the left and right side edges of the flat plate portion are bent in the same direction, and the tip is further inward. It is the composition which folded back and provided the side edge formation part, and it may use the exterior board of the same shape as a mountain side exterior board and the valley side exterior board by arranging upside down and alternately alternately in principle. And the valley side are formed continuously, but it is not necessary to completely match the two. That is, the mountain-side exterior plate and the valley-side exterior plate may be the same up to the details of the configuration, or may be different in the configuration of the details. In addition, various backing materials may be integrally affixed to the back surface, and in particular, as a mountain side exterior plate, a backing material having various functions such as elasticity and airtightness may be affixed to the back surface. It may be attached.
As these exterior boards, although a metal face material which can be made to engage elastically is preferred as a raw material, a hard resin board may be sufficient. In addition, a metal surface material having cosmetic properties (design properties) (also serving as a decorative material) may be used, and for example, the surface plate may be formed to be flat or uneven.

This exterior plate is configured such that side edge moldings are provided on the left and right sides of the flat plate portion, and the side edge molding portions are configured such that the left and right side edges of the flat plate portion are folded up or folded down and their tips are further folded inward. It is.
That is, in the mountain-side exterior plate, the left and right side edges are folded down (= downward side edge forming portion), and the lower end is further folded back inward to form an upper flap (= upward folded portion).
Further, in the valley side exterior plate, the left and right side edges are folded up (= upward side edge forming portion), and the upper end is further folded back inward to form a lower fold (= downward folded portion).
As described above, when arranging the mountain-side exterior plate, the downward side edge moldings of the left and right side edges expand outward in a spreading manner against elasticity, and then elastically recover so as to close inward. The lower side edge forming portion may be folded at least perpendicularly to the flat plate portion disposed substantially horizontally, but it is turned slightly inward from the vertical shape for the purpose of more reliable engagement. It may be formed into

Although these mountain side exterior boards and valley side exterior boards are mutually engaged, it is preferable to make surface contact and engage.
Here, the configuration in which the surface contact is made means that not only the lower flap (the downward fold portion thereof) and the upper fold (the upward fold portion thereof) are disposed at substantially equal inclination angles in the disposition state, but also by the action of elasticity. Refers to a state in which they are attached to each other in a pressure contact manner. Therefore, the lower goby (the downward fold-back part) is shaped so that elasticity (repulsion) acts diagonally downward, and the upper goby (the upward fold-back part) is elastic (repulsion) toward the diagonal upward in advance By molding so as to act, both can be brought into pressure contact in a surface contact manner. In addition, the elasticity may be at least one of the upper and lower eyes if it is configured to be in surface contact.

Further, it is desirable that a space opened upward is formed below the engagement portion.
That is, this space is a corner space formed in the upper lip of the mountain-side exterior plate, and the shape and size thereof are not particularly limited, and any space may be used as long as it prevents capillary action. May be.

Furthermore, the upper side of the mountain-side exterior plate may be provided with a mountain-side contact surface that is further folded inside as an upward turn-back portion, and the lower side of the valley-side exterior plate may be further folded inwardly as a downward turn-up portion. A valley side contact surface may be provided.
That is, the upper gore may be formed only by the upward turning pieces, or may be formed by the upward turning pieces and the mountain side contact surface as in the illustrated embodiment described later, and the lower goes may be only the downward turning pieces. Even in the configuration to be formed, it may be configured as the valley side contact surface in which the tip of the downward turning piece is further folded as in the illustrated embodiment described later. Thus, only one of the mountain side contact surface and the valley side contact surface may be provided, or both may be provided. Therefore, the surface contact is an aspect in which the upward turning pieces and the downward turning pieces are in surface contact, an aspect in which the upward turning pieces and the valley side abutment surface are in plane contact, and an aspect in which the mountain side abutment surfaces and the downward folding pieces are in plane contact The aspect which surface contact of the mountain side contact surface and the valley side contact surface is assumed.

In this case (where the contact surface is provided on either or both of the upper and lower gobs), the above-described configuration for surface contact can be implemented appropriately and easily.
That is, for example, in the case where the upper flap is formed only by the upward turning pieces, since the upward turning pieces are portions brought into surface contact, the folding pieces are also affected. However, when the upper goby is formed by the upward folded piece and the mountain side abutment surface, the ridge side abutting surface is a portion to be brought into surface contact, so there is almost no effect on the fold down piece. Since molding may be performed so as to elastically repel in the direction in which the contact surface expands, molding is easy.

Further, in this case, a space opened by the above-described upper portion is easily formed below the engaging portion.
That is, since the valley side contact surface and the mountain side contact surface elastically come into surface contact, the size of the engagement portion itself becomes large, so it is easy to form a space of a size that prevents the capillary phenomenon. . In addition, since the surface contact in this case is a surface contact having cushioning properties with each other, the upward movement of the upper fly at the time of negative pressure action becomes reliable and easy.

When the holding member having the rising portion having the fixing portion to the ground at the lower end thereof and the folded back portion obtained by turning the upper end of the rising portion outward is fixed on the ground, the valley side exterior plate By arranging the downward turn-back portion of the upward side edge forming portion to be engaged with the inside of the turn-back portion of the holding member, the downward turn-back portion is stably positionally regulated, with respect to the downward turn-back portion. The upward turnup portion of the upper exterior plate can be stably brought into surface contact and engaged.
When the holding member is used as described above, since the engagement of the upper and lower gobys to the holding member is adopted and attached, the intrusion of rainwater from the screw hole and the intrusion of rainwater due to capillary action do not occur. It is excellent in construction, and has an exterior structure that also takes into consideration the strength and water tightness under negative pressure.

The holding member is disposed on the back surface side of the mountain-side exterior plate, and has a rising portion having a fixing portion to a base at its lower end, and a folded portion in which the upper end of the rising portion is folded outwards; It is the composition which has The holding member may be a long material called a through hanging member, or may be a piece material as in the illustrated embodiment to be described later.
In addition, with regard to the attachment of the exterior plate to the holding member, the lower lip of the valley-side exterior plate is directly engaged so as to be accommodated inside the folded portion of the holding member, and the upper lip of the mountain-side exterior plate The upper end of the lower end of the valley side exterior plate may be elastically engaged so as to abut on the lower end of the lower end of the valley side exterior plate. In short, the valley side exterior plate is directly engaged with the holding member, and the mountain side exterior plate is indirectly engaged with the holding member, that is, through the valley side exterior plate.

Further, a heat insulating material may be disposed on the back surface of the mountain-side exterior plate, a separate body may be integrally fixed by an adhesive or the like, or may be integrally attached as a backup material. . In this case, it is needless to mention that the heat insulating function is provided, but in particular, the mountain-side exterior plate can be stably disposed on the holding member in a state of being placed on the surface of the heat insulating material.
Such a heat insulating material also has the effect of improving the strength as a panel.
Further, the heat insulating material is not limited to a synthetic resin boat, for example, and may be a wooden board, or may be a single layer or a multiple layer, or may be a multilayer structure of different materials. Therefore, functional board materials such as flame retardancy and noncombustibility may be used, and there is no restriction on the thickness and the like, and any heat insulating material may be used.

The effects of the present invention will be described in detail. Since the upper and lower engagements are employed, the screw itself is not used as in the conventional screwing method, and the screw hole itself does not exist. There is no penetration of rainwater from the holes. In addition, as in the case of the conventional goby type, it does not cause intrusion of rain water due to the capillary phenomenon, and problems such as time and effort for construction do not occur.
Moreover, since it is the structure engaged using the elasticity of a backing material, exterior plates become what can be attached firmly and stably, and it is excellent also in construction property.

In addition, when the folded portion is brought into surface contact and engaged, even when a negative pressure is applied, the tip of the upper tip of the mountain-side exterior plate is maintained deep (with the capillary phenomenon prevented) while maintaining the surface contact. Since it moves upward and comes in close contact with the lower lip of the valley side exterior plate, there is no gap where blowing occurs, so that blowing can be prevented and high water tightness can be ensured.
Furthermore, when a space opened upward is formed below the engagement portion, rainwater does not enter due to capillary action as in the conventional flapping method. That is, a space provided at the upper side below the engagement portion prevents capillary action, and the space functions as a drainage channel, and even if rainwater which has intruded, can be made to flow down the drainage channel.
In addition, even when negative pressure is applied, the tip of the upper lip of the mountain-side outer plate moves deeply upward while maintaining the surface contact with the lower go (with the capillary phenomenon prevented), and the valley-side outer plate Since it contacts closely with the lower fly, there is no gap where blowing occurs, so that blowing can be prevented and high water tightness can be secured.

  Further, in the structure in which the holding member is fixed between the mountain-side exterior plate and the valley-side exterior plate, in particular, the downward turn-back portion of the lower lip can be positionally regulated stably. It is possible to stably bring the upper edge of the plate into surface contact and firmly engage.

  In the exterior structure of the first embodiment shown in FIG. 1, the left and right side edges of the flat plate portions 11 and 21 are bent in the same direction on the base 4, and the tips thereof are further folded inward to form side edge formed portions 12, 12, 22. , 22 to form the mountain-side exterior plate 1 and the valley-side exterior plate 2, and by alternately arranging them, a mountain portion and a valley portion are continuously formed. That is, the downward side edge molding portion 12 of the mountain-side exterior plate 1 has an upward turn-up portion 124 in which the left and right side edges of the flat plate portion 11 are folded downward and the lower end is folded inward. The two upward side edge moldings 22 are configured to have a downward turnback portion 224 in which the left and right side edges of the flat plate portion 21 are folded upward and the upper end thereof is folded inward. Then, the backing material 1b having elasticity is attached to the back surface of the flat plate portion 11 of the mountain-side exterior plate 1, and the upward turn-up portion 124 of the downward side edge molding portion 12 And is engaged with the downward turning portion 224 of

The mountain-side exterior plate 1 in the first embodiment has a configuration in which the left and right side edges of the substantially flat flat plate portion 11 are folded down and the lower end is further folded back inward to form the upper blind 12. An elastic backing material 1b is additionally provided.
More specifically, as shown in FIG. 2 (b), the upper goe 12 is a downward piece which is a downward piece which is folded inward at the inner end of the fold-down piece 121 and the upward fold-back piece 122 which are disposed substantially vertically when disposed. And an abutting surface 123. That is, the upward turn-back portion 124 in the first embodiment comprises the upward turn-up piece 122 and the mountain side abutment surface 123. The backing material 1 b is formed to have substantially the same thickness over the length direction of the flat plate portion 11.

  Further, the valley side exterior plate 2 in the first embodiment has a configuration in which the left and right side edges of the substantially flat plate portion 21 are folded up, and the upper end is further folded inward to form a lower flap 22. More specifically, as shown in FIG. 2 (b), the lower goby 22 is an upward piece formed by folding up the folding piece 221 and the downward folding piece 222 which are disposed substantially vertically at the time of arrangement and the tip thereof inward. And an abutment surface 223. That is, the downward turnback portion 224 in the first embodiment comprises a downward turnback piece 222 and a valley side abutment surface 223. In addition, on the back surface side of the flat plate portion 21, a backing material 2b of substantially the same thickness is attached.

  And as these mountain side exterior board 1 and valley side exterior board 2 are shown in FIG.2 (c), the direction which arrange | positions backing material 1b, 2b shape | molds a metal material in the completely same shape except the reverse direction. It is Further, as the backing materials 1b and 2b, a hard urethane foam having elasticity and airtightness can be used.

In the first embodiment, a holding member 3 which is a piece material is disposed on the back side of the mountain-side exterior plate 1.
The holding member 3 has a rising portion 32 having a fixing portion 31 to the base 4 at the lower end as shown in FIG. 2C, and a folded portion 33 in which the upper end of the rising portion 32 is folded outward. It is.
The fixing portion 31 extends in a substantially horizontal shape, and fixes a fixing tool (indicated by a two-dot chain line) into the recess 311 from above from above to fix it to the base 4.
Further, the folded back portion 33 is disposed to face outward, and is formed to face to the left in almost all the drawings, and in the holding member 3 disposed to the right in FIG. The portion 33 is disposed to turn to the right.

And in the exterior structure of this invention comprised from these members, about attachment of the said exterior boards 1 and 2 to the said holding member 3, as shown in FIG.2 (b), the lower haze of the valley side exterior board 2 is carried out. While being engaged so as to be accommodated inside the folded back portion 33 of the holding member 3, the upper hook 12 of the mountain-side exterior plate 1 is engaged in surface contact with the lower hook 22. That is, as described above, the valley side exterior plate 2 is directly engaged with the holding member 3, and the mountain side exterior plate 1 is indirectly engaged with the holding member 3 via the valley side exterior plate 2. It is.
In the first embodiment, as described above, the upper fly 12 is composed of the fold-down piece 121, the upward turn-up piece 122, and the mountain-side contact surface 123 folded inside the tip thereof. Since the configuration is composed of the folded up piece 221, the downward folded up piece 222, and the mountain side contact surface 223 in which the tip is folded inward, the surface contact between the upper goe 12 and the lower goe 22 is specifically a mountain shape. This is surface contact between the contact surface 123 and the valley-like contact surface 223.

The foundation 4 has a construction in which the waterproof sheet 4b is laid on the surface of the base material 4c having a substantially constant thickness in FIG. 1, but as shown in FIG. 3 (b), the base material 4c is a driven body (C-shaped steel 2) fixed on 4d and shown by a broken line in FIG. 2 (a).
Further, the heat insulating material 5 having a substantially rectangular cross section is disposed between the valley-side exterior plates 2 adjacent to the back surface of the mountain-side exterior plate 1, that is, to the left and right.

The installation procedure of the exterior structure of this invention comprised from such each member is demonstrated easily below.
First, the holding member 3 of the above configuration is fixed on the base 4 at a predetermined interval.
In this process, the holding member 3 is attached in advance according to the size of the valley side exterior plate 2, but the holding member 3 is disposed so that the folded portion 33 faces the valley side exterior plate 2 to be disposed. The fixing tool 3b is driven into the fixing portion 31 from above and fixed to the base 4 (the frame 4d).

Next, the lower flaps 22 (downward turnup pieces 222) of the valley side exterior plate 2 are engaged with the turnup portion 33 of the holding member 3 fixed on the base 4 as described above. In this process, the heat insulating material 5 may be attached to the disposition interval of the holding members 3 and 3.
In this process, the valley side exterior plate 2 may be disposed so as to drop the valley side exterior plate 2 between the adjacent holding members 3 and 3.

  Subsequently, the mountain-side exterior plate 1 is attached to the valley-side exterior plate 2 so as to face the upper side and to be pressed downward. When the mountain-side exterior plate 1 is disposed, the heat insulating material 5 may be simultaneously disposed so as to be held, or only the heat insulating material 5 may be attached in advance as described above.

In this process, as shown by the hatching in the left half of FIG. 1 (a), the mountain-side exterior plate 1 is pushed down as the mountain-side exterior plate 1 is pressed downward, and the backing material 1b resists elasticity. The upper flaps 12, 12 (upwardly folded pieces 122, 122) of the upper flaps 12, 12 expand outwardly against the elasticity while in contact with the lower folds 21, 21 (downwardly folded pieces 222, 222).
Here, with regard to the thinning of the backing material 1b performed against the elasticity and the expansion of the upper flaps 12, 12, the upper end of the upward folding piece 122 passes the lower end of the downward folding piece 222 of the lower flap 21, 21. The process is performed until the gap X shown in the drawing is formed.

  Thereafter, the upper fly 12 (upwardly folded piece 122) which has been spread outward against the elasticity elastically recovers inward as indicated by hatching, so that the mountain-like contact surface of the upper fly 12 is finally obtained. The surface contact 123 engages with the valley-like abutment surface 223 of the lower blind 22.

In the exterior structure of the present invention constructed in this manner, the engagement of the upper blinds 12 and 12 and the lower blinds 22 and 22 is adopted, and moreover, the construction is made to engage using the elasticity of the backing material 1b. It is also excellent in construction. In particular, since the goes 12 and 22 are engaged using the elasticity of the backing material 1b, the exterior plates 1 and 2 can be attached firmly and stably.
Thus, since it can be made to elastically engage (fit) and attach by simple operation which only presses mountain side exterior board 1 below from the upper part, construction nature is extremely excellent.

  Next, although effects other than the workability of the exterior structure of the present invention will be described based on FIG. 4, FIG. 5A, FIG. 6A, and FIG. It demonstrates, comparing with FIG.5 (b) and FIG.6 (b) which show the flap-fastening type exterior structure of 1. FIG.

First, in FIG. 4A, hatching is applied to the “surface contact” location adopted in the first embodiment, and in FIGS. 4A and 4C, cross hatching is applied to the space 13 opened above. gave. Moreover, in order to show the waterproof effect in FIG.4 (b), the permeation | transmission path | route of the rain water assumed is shown.
As shown in FIG. 4 (b), a space 13 is formed below the engagement portion (123, 223), so that the space 13 prevents capillary action and the space 13 is a drainage channel. In the unlikely event that rainwater that has infiltrated can also flow down this drainage channel (13).
Further, “surface contact” refers to surface contact and engagement between the mountain side contact surface 123 formed on the upper goby 12 and the valley side contact surface 223 formed on the lower goby 22 as described above, It is an arrangement in which a close engagement like a conventional goby type is never performed.
Furthermore, the airtight backing material 1b attached to the back surface of the mountain-side exterior plate 1 blocks the path blown by the wind and rain. Therefore, as shown by dotted arrows in the figure, in order for water to infiltrate into the inside, it has to be blown up beyond the backing material 1 b and the lower lid 22, so the waterproofness is high.

On the other hand, the space 13 for preventing such a capillary phenomenon is not formed in the conventional screw fastening method or the conventional goby type, and the same effect is not exhibited either, as shown in FIGS. 5 (a) and 5 (b). it is obvious.
That is, although the conventional screwing specification is shown in FIG. 5 (a), as indicated by the thick line, the rainwater W traveling on the surface of the mountain side exterior plate 6 is the side edge formed portion 62 of the mountain side exterior plate 6 and the valley. It will infiltrate from the screw hole of the fixing screw 7 pierced from the side into the polymerization part with side edge molding part 62 'of side exterior board 6'.
Further, FIG. 5 (b) shows the conventional goby tightening specification, but as also shown by the thick line, the rainwater W traveling on the surface of the mountain side exterior plate 8 is the valley side exterior plate 8 'and the suspension 9 Infiltrates into the interior from capillary tightening by capillary action. That is, in the engagement according to this specification, as shown in an enlarged manner in FIG. 5C, the upward turnup piece 821 provided on the upper fly 82 and the downward turnup piece 831 provided on the lower fly 83 closely engage with each other. Because the engagement portion 92 of the suspension 9 is engaged, a capillary phenomenon occurs and rainwater intrudes into the inside.
In these conventional specifications, even if the watertightness of the screw hole and the gouged part is improved by using a sealing material excellent in water proofing, the sealing material is aged with time and the rainwater will infiltrate. .

Next, based on FIG.4 (c), the waterproofing performance at the time of the negative pressure action of the exterior structure of this invention is demonstrated.
As shown in FIG. 4 (c), when a negative pressure caused by a blowing wind or the like acts, a force that normally pulls up the horizontal flat plate portions 11 and 21 upward as shown by white arrows in the figure. (Negative pressure) acts to cause a phenomenon of being deformed in a convex shape upward. At that time, since the lower flap 22 of the valley side exterior plate 2 is in contact with the holding member 3 before the negative pressure action, a force (negative pressure) of pulling upward acts on the upper haze 12 of the mountain side exterior plate 1, As shown by the hatching arrows, the mountain side contact surface 123 is pulled up so as to slide upward while being in contact with the valley side contact surface 223 of the lower goby 22, and the mountain side contact surface 123 and the upper end of the upward turning piece 122 are , And abut on the fold-up piece 221 of the valley side exterior plate 2. Further, the lower fly 22 pulled up by the pressure from the lower side of the upper fly 12 compresses the backing material 1b located above the lower fly 22 in a compressed state.
As described above, when negative pressure is applied, the upper fly 12 and the lower fly 22 are engaged more deeply than in a state where no negative pressure is applied, and it becomes difficult to remove.

In addition, since the mountain-side exterior plate 1 and the valley-side exterior plate 2 are formed into the same shape, the folded-down piece 121 of the upper haze 12 of the mountain-side exterior plate 1 with the behavior of being pulled up above the upper haze 12 It abuts on the valley side abutment surface 223 of the lower flap 22 and the lower end of the downward turning piece 222.
Thus, when the goes 12 and 22 contact the vertical wall (folded pieces 221 and folded pieces 121), two independent spaces 13 and 23 are generated, and the entry of water by capillary action is prevented.
Also, the space 13 below the engagement portions 123, 223 is closed at the top, while the space 23 located above the engagement portions 123, 223 is open at the bottom before negative pressure action, When a negative pressure acts, the lower side is closed as described above, the gap disappears, and wind and rain are prevented from blowing. Moreover, as described above, since the backing material 1 b is pressed in a compressed state from the downward turning pieces 222 of the lower goug 22, there is no gap in which water intrudes into the inside, so the waterproof property is extremely high.

On the other hand, FIG. 6A shows the negative pressure action time in the conventional screwing specification, but even if the screw 7 itself does not come off, the side edge formed portion 62, which is the closest to the screw 7, A deformation occurs in 62 ', and in this state, predetermined characteristics can not be obtained.
Further, FIG. 6 (b) shows the time of negative pressure action in the conventional goby specification, but a part of goby tightening is released by the pulling action due to the underpressure, and as described above, the above goby Since the upward turnback piece 821 provided at 82 and the downward turnback piece 831 provided at the lower hook 83 closely engage with each other and engage with the engagement portion 92 of the suspension 9, the capillary phenomenon occurs. In this state, no predetermined characteristics can be obtained.

2 (b) and 2 (c) show the exterior plates 1 and 2 and the holding member 3 used in the first embodiment, but not the state at the time of molding (= before assembly). It shows each member in an assembled state.
Further, as described in FIG. 4C, when a negative pressure is applied, the upper end of the mountain side contact surface 123 and the upper end of the upward turnup piece 122 is in contact with the turnup piece 221 of the valley side exterior plate 2. The folded piece 121 of the mountain-side exterior plate 1 abuts on the lower end of the valley-side contact surface 223 of the lower goug 22 and the downward turning piece 222, but in the normal laying state, the folding piece 221 and the upward turning portion The folded piece 121 and the downward turning portion 224 are not in contact with each other. That is, it is possible to prevent the suction of rain water at the normal time by not contacting at least the fold-down piece 221 and the upward turn-up piece 124 (it becomes an open downward space so that the sprayed rain water does not accumulate) Flow down naturally).
