Japanese Patent No. 3171538 (paragraph number 0014, FIG. 7) JP 2000-320078 (paragraph number 0011, FIG. 3)

However, since both Patent Document 1 and Patent Document 2 have a configuration in which the protruding piece (locking piece) formed on the hanging member (holding member) is in contact with the upper collar part (eave side molding part) at all times or at the time of negative pressure action, In Patent Document 2, the tip of the locking piece repeatedly collides (contacts) with the back surface of the eaves-side molded part by the action of negative pressure, which may cause cracks or perforations. Further, in Patent Document 1, not only during negative pressure operation, but because the tip of the protruding piece is always in contact with the back surface of the upper collar part, the upper collar part is easily damaged due to wear due to vibration or the like. Met. And when such damage arises in the upper collar part (eave side molding part), there existed a possibility of producing a water leak and a connection defect.
Therefore, the present invention has a high installation strength of the connecting portion of the side covering material disposed under the water and above the water even when the side covering material is lifted during the negative pressure action, and has a good negative pressure strength. The purpose is to propose an exterior structure.

The present invention has been proposed in view of the above circumstances, and has a water-side molded portion and a water-side molded portion that can be engaged with each other on the water surface and water surface of the face plate portion, and is negative on the water side of the holding portion. It is a horizontal covering material laid using a holding member having a pressure suppressing piece, and the water-side molded part is formed at the corner where the face plate part is bent to the surface side and the bent piece rises from the face plate part. It has an engaged part and a held part where the upper end of the bent piece is turned back toward the bent base part, and further has an extended piece on the lower side thereof. Is bent to the back side, and has a pressed piece located on the back side of the extended piece with its lower end extending to the water side, and further engaging the engaged portion on the water side. In the laying state, the holding part of the water-side molded part is held by the holding part of the holding member and the pressed piece elastically contacts the back side of the extended piece. In combination, the negative pressure suppression piece of the holding member faces the extension piece in a non-contact manner, and the negative pressure suppression piece of the holding member can be laid so as to press the pressed piece through the extension piece during negative pressure action. The present invention relates to a horizontal covering material characterized by the above.

When the outer covering material of the present invention is used in combination with a holding member having a negative pressure suppressing piece on the water side of the holding portion, the negative pressure suppressing piece of the holding member extends when the outer covering material is lifted during the negative pressure action. Since the pressed piece is pressed through the protruding piece, the negative pressure strength is high, and the effect of preventing the water-side molded portion from coming off is achieved. Further, the extending piece also serves as a cover material that prevents the negative pressure suppressing piece of the holding member from coming into direct contact with the pressed piece (water-side molded portion). Even if the extension piece is damaged, the damage to the extension piece is located on the water underside of the held portion, so that it does not affect the holding by the holding member and causes water leakage and poor connection. There is no fear. Therefore, it is continuously and firmly connected and attached.
Furthermore, since the extending piece and the pressed piece are elastically in contact with each other even in a laying state other than during the negative pressure operation, a high effect is exhibited particularly in engagement and removal prevention.

  The horizontal covering structure of the present invention has a horizontal covering material (hereinafter referred to as the following) having a water-side molding part 3 and a water-side molding part 4 that can be engaged with each other on the water surface / water side of the face plate part 2 as described above. 1) simply by using a holding member 5, and when the exterior material 1 is lifted during a negative pressure operation, the negative pressure suppression piece 54 of the holding member 5 is formed on the water-side molded part 4 It is the structure which presses down the to-be-pressed piece 32 formed in the underwater shaping | molding part 4 through the extension piece 43 formed in this.

The water-side molded portion 4 of the exterior material 1 used in the present invention is bent at the water-side edge of the face plate portion 2 to the surface side as a basic configuration, and the corners or bent pieces (hereinafter referred to as upward bent pieces). ) 44 with an engaged portion 41, a held portion 42 in which the upper end of the upward bent piece 44 is folded back toward the bent base portion, and an extending piece 43 formed under the water. is there.
The engaged portion 41 may be formed in a corner shape in which the end edge of the face plate portion 2 is folded back into a circular arc shape (groove shape) as in the embodiment shown in FIG . Further, the upward bent piece 44 may be upright, may be inclined downwardly as in the embodiment shown in FIG. 1, or may be composed of a plurality of inclined pieces.
Further, the held portion 42 is a portion that is held by a holding portion 51 of the holding member 5 described later, and may be inclined downwardly as in the embodiment shown in FIG. It is not limited.
Further, it is desirable that the extending piece 43 has a valley shape in which the negative pressure suppressing piece 54 of the holding member 5 contacts and does not move during the negative pressure action, and extends downwardly as in the embodiment shown in FIG. It may be formed in a substantially U shape that is inclined, bent gently, and further inclined upward (substantially arc shape whose cross section protrudes downward). This is because the extension piece 43 may be damaged due to friction if it moves in a contact state. The extension piece 43 is pressed against the pressed piece 32 located on the back side thereof by the negative pressure suppressing piece 54 of the holding member 5 coming into contact with the exterior material 1 when the negative pressure is applied. However, in the embodiment shown in FIG. 1, the substantially central portion of the extending piece 43 is in elastic contact with the pressed piece 32 located on the back side even in a laying state where no negative pressure is applied. .

The underwater molding part 3 of the exterior material 1 used in the present invention bends the underwater edge of the face plate part 2 to the back side as a basic structure, and a bent piece (hereinafter referred to as a downward bent piece). The lower end of 33 is extended to the water side and has a pressed piece 32 positioned on the back side of the extended piece 43, and the engaging portion 31 that engages the engaged portion 41 on the water side. It is the structure which has.
The engaging portion 31 is a portion that engages with the engaged portion 41 and is not particularly limited in shape. Further, the downward bent piece 33 may be bent so as to extend further downward from the face plate portion 2 as in the embodiment shown in FIG. 1, or may be bent downwardly. It may be bent so as to extend upward.
Further, the shape of the pressed piece 32 is not particularly limited, and may be flat or valley-shaped, or may be a gentle mountain shape (substantially arc shape whose cross section protrudes upward) as in the embodiment shown in FIG. You may form in. In the embodiment shown in FIG. 1, the pressed piece 32 is in elastic contact with the substantially central portion of the extended piece 43 even in a laying state where no negative pressure is applied.

  The exterior material 1 having such a structure is not particularly limited, but typically is a surface-coated steel sheet, a laminated steel sheet, a plated steel sheet, a stainless steel sheet, an aluminum alloy of about 0.4 to 1.6 mm. A known metal material such as a plate, a titanium alloy plate, or a copper plate is formed into a predetermined shape by roll forming or other means. In addition, it can shape | mold to the same shape also with a hard resin board, a carbon fiber laminated board, etc., can also construct with them all, and can also construct in combination with the said metal raw material thing. In addition, a backing material such as polyethylene foam or glass wool sheet may be attached to the back surface of the exterior material 1 as necessary for reasons of preventing condensation, soundproofing, and fireproofing. In the illustrated embodiment, the backing material is indicated by a dotted line with reference numeral 10. Further, the backing material 10 prevents the tip of the negative pressure suppressing piece 54 of the holding member 5 from repeatedly colliding (contacting) directly with the extending piece 43 of the water-side molded part 4 due to the negative pressure. It also contributes to preventing the occurrence of cracks and perforations.

The holding member 5 used in the present invention has a fixing part 52, an inclined part 53, a holding part 51 for holding the exterior material 1, and a close proximity (non- This is a configuration having a negative pressure suppression piece 54 facing in a contact state.
The negative pressure suppressing piece 54 may be a hanging shape or a downward inclined shape, and a downward negative pressure suppressing piece 54 may be provided so as to branch from the holding portion 51 as in the embodiment shown in FIG. It is good also as the negative pressure suppression piece 54 of the downward inclination shape so that the lower end of the holding part 51 may be bent and it may continue from the holding part 51 like the Example shown. Since the negative pressure suppression piece 54 contacts the extension piece 43 during the negative pressure operation, the lower end of the negative pressure suppression piece 54 is folded back for the purpose of preventing the occurrence of cracks and perforations due to repeated contact. The contact area may be increased by forming it in a round shape or in a shape that matches the shape of the contact portion of the extension piece 43, and the contact portion with the extension piece 43 may be elastic. You may make it prevent contact | abutting of metal materials by apply | coating a resin coating material.

The side-facing exterior structure shown in FIG. 1 lays the exterior material 1 having the above-described configuration using the holding member 5 having the above-described configuration, and its construction procedure is described below with reference to FIGS. 2 (a) to 2 (c). Explained.
First, as shown in FIG. 2A, the holding member 5 is fixed so that the held portion 42 of the water-side molded portion 4 of the exterior material 1 arranged on the water side is held by the holding portion 51 (fixing tool). 521).
Next, as shown in FIG. 2 (b), the water-side molding portion 3 of the exterior material 1 arranged on the water side is moved so as to slide from the water side toward the water side. The extended piece 43 is pushed up against elasticity by the pressed piece 32 of the portion 3.
Then, as shown in FIG. 2 (c), when the engaging portion 31 of the exterior material 1 disposed on the water side is engaged with the engaged portion 41 of the exterior material 1 disposed on the water side, In the laid state, the extended piece 43 slightly returns due to elasticity, but elastically contacts the pressed piece 32.
By laying the exterior material 1 sequentially from the water side to the water side in such a procedure, a side-by-side exterior structure can be constructed.

  When the exterior material 1 is lifted during the negative pressure operation as shown in FIG. 1B, the side-facing exterior structure of the present invention constructed in this way is the extension piece 43. Since the pressed piece 32 is pressed via the negative pressure, negative pressure is suppressed, and an effect such as prevention of the water-side molded portion 3 from coming off is achieved. Further, the extending piece 43 also serves as a cover material that prevents the downward negative pressure suppressing piece 54 of the holding member 5 from coming into direct contact with the pressed piece 32 (the underwater molding portion 3). Even if the extended piece 43 is damaged, the extended piece 43 is located on the underwater side of the held portion 42, so that the holding member 42 holds the held portion 42. Without giving, there is no possibility of causing water leakage or poor connection, and it is firmly and securely connected and attached.

Moreover, it has not only excellent negative pressure strength but also excellent positive pressure strength as shown in FIG.
When a positive pressure load is applied by a blowing wind or the like, the holding part 51 of the holding member 5 and the water-side molded part 4 support the outer packaging material 1 above the part surrounded by a circle as shown in FIG. . That is, even if the exterior material 1 is pushed by a positive pressure load, the water-side molded part 4 of the water-side exterior material 1 and the holding part 51 of the holding member 5 are supported, so that the positive pressure strength is excellent.

  Further, in the illustrated embodiment, the extending piece 43 of the water-side molding part 4 is formed in a substantially arc shape whose section projects downward, and the pressed piece 32 of the water-side molding part 3 projects upward. Therefore, the extension piece 43 and the pressed piece 32 may come into surface contact with each other and damage the pressed piece 32 when pressed by the negative pressure suppressing piece 54 during the negative pressure action. Absent.

In the illustrated embodiment, as described above, the substantially central portion of the extending piece 43 and the pressed piece 32 are in elastic contact with each other. Specifically, the configuration shown in FIG. ing.
That is, the downward inclination angle of the extending piece 43 is formed larger than the angle α1 in the laying state, and in the laying state, it is laid so as to have a small angle α1 by elastic contact with the pressed piece 32. An elastic repulsion force always acts on the contact portion. Further, the upward inclination angle of the pressed piece 32 is formed larger than the angle α2 in the laying state, and in the laying state, it is laid so as to have a small angle α2 by elastic contact with the extending piece 43. The elastic repulsive force always acts on the contact portion.
Such elastic contact is not limited to adjusting the two angles as described above, and only one of them may be adjusted. Also, the configuration for elastic contact may be elastically contacted by adjusting the angle of a bent or bent portion of each part of the exterior material 1 or a combination thereof.
Such an elastic contact provides an engagement effect and contributes to retaining.

Further, in the illustrated embodiment, as shown in FIG. 3B, a folded piece-like second contact portion 35 is formed by folding the engaging portion 31 downward, and the second contact portion 35 is inclined downward. The angle was formed larger than the angle α3 in the laying state. In the laid state, the elastic contact with the face plate portion 2 is laid so as to have a small angle α3, so that an elastic repulsive force always acts on the contact portion.
In addition, the above-described downward inclination angle is adjusted as a configuration in which the second contact portion 35 inclined downward as described above is provided and the second contact portion 35 and the face plate portion 2 are in elastic contact with each other in the laying state. It is not limited to what is to be done, and it may be elastically brought into contact with each other by bending or adjusting the angle of each part of the exterior material 1 or a combination thereof.
By such elastic contact, the introduction port of rainwater to the connecting portion is elastically blocked, exerts an effect on rain performance, and further, the engagement portion 31 and the engaged portion 41 are close to each other. Combined with the engagement, a strong bond (contact) is achieved.

Further, in the illustrated embodiment, as shown in FIG. 3B, the engaging portion 31 and the engaged portion 41 are not only engaged but elastically abutting, and the engaging portion 31 is a third member. The abutting portion 36, and the engaged portion 41 is a third abutted portion 47. The outer width of the third abutting portion 36 is formed to be larger than the outer width r1 in the laid state, that is, the inner width of the third abutted portion 47. In the laid state, the outer width of the third abutting portion 36 is elastic. Since it is laid so as to be pushed and narrowed by a natural contact, an elastic repulsive force always acts on the contact portion.
As a configuration in which the third abutting portion 47 is formed in a groove shape and the third abutting portion 36 is formed in a projecting shape in this way, the third abutting portion 47 is formed in a protruding shape. It is possible to make the third contact portion 36 elastically contact with the third contact portion 36 by forming it smaller or by making the third contact portion 36 larger than the third contact portion 47. Or it can also be made to contact | abut elastically by adjusting the angle (as soon as elastic force is provided) of another location. For example, when the angle between the fourth contact portion 37 and the downward bent piece 33 is reduced, the third contact portion 36 provided at the tip of the extended piece is lifted upward to elastically move to the third contacted portion 47. When the downward inclination angle of the second contact portion 35 is increased, the third contact portion 36 adjacent to the second contact portion 35 is lifted upward to be elastically contacted with the third contacted portion 47. These may be combined and elastically contacted.
By such elastic contact, the engaged state between the engaged portion 41 and the engaging portion 31 becomes more reliable by elasticity, so that particularly strong bonding is achieved.

Furthermore, in the illustrated embodiment, as shown in FIG. 3B, a planar fourth contact portion 37 is provided at the base end of the pressed piece 31 that extends the lower end of the downward bent piece 33 to the water side. The angle of the fourth contact portion 37 and the downward bent piece 33 is formed smaller than the angle α4 in the laying state, and is larger due to the elastic contact with the face plate portion 2 in the laying state. Since it is laid so as to have an angle α4, an elastic repulsive force always acts on the contact portion.
Note that the configuration in which the fourth contact portion 37 is elastically contacted with the face plate portion 2 in this way is not limited to the above-described aspect, and the angle between the face plate portion 2 and the downward inclined piece 33 is laid. An aspect in which the angle is smaller than the angle in the state may be used.
By such elastic contact, the rainwater introduction port to the connecting portion is elastically blocked, and the effect on rain performance is particularly high. Further, a strong joint (contact) is achieved in combination with the elastic contact that prevents the pressed piece 32 from being lifted or the elastic contact at the third contact portion 36.

And together, each forms the independent space shown by AC in FIG.3 (c), becomes a structure approximated to the isobaric theory, and becomes excellent in rain performance.
Such elastic contact can be firmly and securely connected and attached by appropriately selecting and applying at least two of the above-described aspects. And there is no backlash etc., and it has high waterproofness and connection strength.

  In the embodiment shown in FIG. 4, the embodiment shown in FIG. 1 is used except that the holding member 5 is used as the negative pressure suppressing piece 54 that is inclined downward so that the lower end of the holding portion 51 is bent and continues from the holding portion 51. The same reference numerals are attached to the drawings, and the description thereof is omitted.

FIG. 5 shows some of the variations of the water-side molded part 4, the water-side molded part 3, and the holding member 5 of the exterior material 1. Incidentally, in each example except for FIG. 5B, the extended piece 43 and the pressed piece 32 are always elastically in addition to the negative pressure action as in the embodiment of FIG. 1 and FIG. It is in contact.
FIG. 5A shows the negative pressure suppression piece 54 of the holding member 5 formed into a shape that matches the shape of the abutting portion of the extension piece 43, and makes surface contact with the extension piece 43 during negative pressure action. It is possible to prevent the occurrence of cracks and perforations due to repeated contact.
FIG. 5B is an example in which the pressed piece 32 of the underwater molding portion 4 is formed into a flat shape, and the pressed piece 32 may have any shape as described above.
FIG. 5C is an example in which the extended piece 43 of the water-side molded part 4 is formed in a folded shape, and the extended piece 43 and the pressed piece 32 are in elastic contact with each other in a surface contact state. Yes.
