Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertically-roofed (vertical) exterior structure to be installed on a roof or wall of a building, and more particularly to a vertically-roofed exterior structure having excellent rain warding performance and strength performance.

[0002]

2. Description of the Related Art Conventionally, various kinds of vertical roofing exterior structures for construction have been proposed. However, vertical roofing exterior materials having rising portions on the left and right side edges of a substantially flat face plate are laid and adjoined vertically. As the most well-known method of covering and covering the outer covering material with a cap, and holding and fixing it on the outer surface base with a holding member such as a suspender
There is a roof bar type roofing roof structure disclosed in Japanese Patent No. 6184. In this type of roof tile roof, the upper end of the rising portion of the side edge of the exterior material, the upper end of the hanger, and the left and right side ends of the cap are integrated by a goby tightening operation, and many improvement proposals have been made. However, this type of roof tile roof causes a fall accident or a water leakage accident of the exterior material during typhoon or after the passage of typhoon, or deteriorates the design (significant deformation of the face plate portion). Therefore, the applicant repeatedly studied the causes of these accidents, and came to judge that the main cause is the following displacement characteristics of the vertically-roofed exterior material under load. That is, basically, the load acting on the exterior surface is a uniform load regardless of the positive load or the load weight, but in the tile roof, the rigidity is high in the projecting bar portion, whereas the load applied to the exterior substrate Since the face plate part in the center of the vertically-roofed exterior material, which has no fixed relationship with, has low rigidity (is flexible), the maximum displacement due to the load applied by a large typhoon or heavy snowfall occurs in the center of the face plate part. When displacement occurs in the center of the face plate portion, the base portion of the rising portion follows the displacement and is displaced toward the center of the exterior covering material. And if a large typhoon, heavy snowfall, or repetition of these occurs multiple times, the base portion of the rising portion will plastically deform, and the initially expected strength performance will not be exhibited, so in the worst case, the fall accident will result. . In other words, the basis of the rain-end is the existence of the rising part,
When deformation occurs in the rising part and its base, for example, when lap joints are made with a standard length vertical roofing material, the amount of deformation and displacement generated in the upper and lower vertical roofing materials at the lap joint part. There is a risk that a gap may occur in the rising part due to the difference between the two, resulting in a water leakage accident. Therefore, the applicant has provided an upright standing portion on a holding member for holding the exterior material on the base, and by engaging the upright portion with the exterior material, the load weight due to the windward wind pressure or the positive load during heavy snowfall. It was found that the displacement and deformation of the exterior material in the working width direction during operation can be suppressed.

[0003]

However, rainwater infiltrates from the gap between the exterior material and the holding member due to the flowing water pressure due to strong winds or the capillary phenomenon, and at the same time, the leaf debris and dust enter with the rainwater. However, rain performance will be reduced. This phenomenon becomes more prominent when the holding member and the exterior material are elastically deformed by the strong wind to temporarily expand the gap. Also, if there is a forming error during roll forming of the exterior material or during extrusion forming of the holding member, or if there is an error in construction, a fitting failure will occur,
Apparently, even if the connection relationship is maintained, if the gap between the exterior material and the holding member is larger than a predetermined value, the possibility of water infiltration from that location increases.

[0004]

Cover material 4 used in the embodiment shown in FIG.
Is a fitting portion 4 that is folded back inward at the left and right lower edges of the adhered portion 42 that is inclined leftward and rightward from the flat top portion 41.
3,43. Since the cover member 4 may also serve as the upper holding member 2B, the cover member 4 is not an indispensable structure and may be attached by a known means such as fitting, engagement, direct fixing with a screw or the like, and the upper holding member 2B in advance. It may be integrated with. The cover material 4 is basically made of the same material as the exterior material 1, and may be an extrusion molded product made of aluminum or hard resin. The material thickness is not particularly limited, but in the case of an extrusion molded product, it is generally 1.2 to 2.
It is about 5 mm.

The exterior structure of the embodiment shown in FIG. 1 is composed of the exterior material 1, the holding member 2 and the cover material 4, and may be constructed by the following procedure.

First, the lower holding member 2 is placed at a predetermined position on the substrate 3.
A is arranged, and a fixture 211 such as a screw is driven into the attachment portion 21 of the lower holding member 2A and attached to the base 3.

Next, the exterior material 1 is attached to the attached lower holding member 2A. At that time, the standing portion 23 of the holding member 2A is located in the space on the back side of the inner rising portion 121 of the exterior material 1, the upper half portion of the outer rising portion 123 is along the supporting oblique side portion, and the engaging portion 1231 is covered. It is arranged so as to elastically engage with the engaging portion 24. In this state, the upward standing portion 23 of the lower holding member 2A engages with the inner rising portion 12 of the exterior material 1 and suppresses its displacement in the working width center direction. Further, the outer rising portion 123 of the exterior material 1 is
In the non-combined state, since it is formed so as to incline outward more than the combined state with the holding member 2, its upper half portion elastically adheres to the supporting hypotenuse of the lower holding member 2A, and the engaging portion 1231 and Since the engaged portion 24 is elastically engaged with the engaged portion 24, the inner rising portion 121 and the rising portion 2 described above are engaged.
Combined with the engagement with 3, the exterior material 1 has high safety against gusts during construction, and consideration was given to the increase in public awareness of safety as seen in recent PL law enforcement. Will be things.

Subsequently, the upper holding member 2B integrally attached with the elastic water blocking material is attached to the lower holding member 2A. At that time, the pair of left and right connecting portions 26 of the upper holding member 2B
Is fitted and integrated with the pair of left and right connection receiving portions 25 of the lower holding member 2A, and the lower surface of the water blocking holding portion 22 is attached so as to press the top portion of the inner rising portion 121 of the exterior material 1. In this state, the inner rising portion 1 of the exterior material 1
Since 21 is pressed and held by the water stop holding portion 22 of the upper holding member 2B, rainwater will infiltrate even if the exterior material 1 and the holding members 2 (2A, 2B) are temporarily elastically deformed by strong wind. Since there are no gaps, the rain performance is extremely high. Further, since the inner rising portion 121 is pressed by the water stop holding portion 22, even if the inner rising portion 121 receives tensile stress toward the face plate portion 11 due to the face plate portion 11 fluttering due to negative pressure, etc. The load generated from the upper holding member 2B and the upper side does not occur, and the water holding portion 22
Since it is supported by the inner rising portion 121, and particularly by the standing portion 23 located on the back surface side in this illustrated embodiment, it has high durability strength against both positive load and load weight. Will have. Further, in addition to the elastic engagement between the engaging portion 1231 and the engaged portion 24, the engagement between the inner rising portion 121 and the rising portion 23, the exterior material 1 also presses the inner rising portion 121 by the water blocking holding portion 22. The holding and the outer rising portion 123 (the upper end and the outside of the engaging portion 24) by the wing piece portion (hereinafter referred to as the pressing portion 28) are extremely stably held.

Thereafter, the fitting portions 43, 43 of the cover material 4 are
Is the fitted portion 27 for the cover material of the upper holding member 2B located outside the inner rising portion 121 (water blocking holding portion 22),
Attach it by fitting it to 27. Therefore, the cover material 4
Even if rainwater enters through the gap between the (fitting portion 43) and the upper holding member 2B (fitting portion 27 for the cover material), a phenomenon occurs outside the inner rising portion 121 and the pressed portion of the water blocking holding portion 22. Therefore, it does not affect rain performance. Further, in the illustrated embodiment, the cover member 4 and the upper holding member 2B may be integrated in advance and attached to the lower holding member 2A.

As described above, in the exterior structure of the present invention, not only the rain retaining performance is improved by closing the gap into which rainwater enters but also the waterproof holding portion 22, and the exterior material 1 and the holding member 2 (2A, 2A, By improving the integrity with 2B), the strength performance can also be improved. Therefore, even if the holding member 2 (2A, 2B) or the exterior material 1 is elastically deformed temporarily by a strong wind or the like, there is no gap for rainwater to enter, and when the exterior material 1 is roll-formed, If there is a forming error during extrusion molding of the holding member 2 (2A, 2B), or if there is an error in construction,
The gap between the exterior material 1 and the holding member 2 (2B) is the water-stop holding portion 2
If it disappears by 2, there is no possibility of flooding from that location. Further, in the illustrated embodiment, the water blocking holding portion 22 of the upper holding member 2B is formed by accommodating the elastic fixed water blocking material in the groove-shaped portion, so that the elastic water blocking material is generated even when a large external force such as an earthquake occurs. A stable structure is maintained without slipping off. In addition, when the elastic fixed water stop material forming the water stop holding portion 22 is aged and loses elasticity due to long-term use, and thus a minute gap is partially generated, a minute amount from the minute gap is generated. However, even in such a case, it is possible to prevent the invasion of leaves and debris from the leaves, and a small amount of water that has infiltrated is smoothly drained toward the eaves in the drainage channel 122 and discharged from the eaves. be able to. The same applies to a case where an elastic irregular water-stopping material such as a waste rubber material is tightly compressed and housed in a groove-shaped space or the like to form the water-stop holding portion 22, or an elastic material having no water-tightness is used. It is possible to prevent the intrusion of most of the rainwater and the invasion of leaf fragments, dust, etc., and a small amount of the intruded water can be smoothly drained down the drainage channel 122 toward the eaves and discharged from the eaves. When a liquid injection type sealing material is filled in the groove-shaped space or the like to form the water blocking holding portion 22, the hardened sealing material may or may not have elasticity, but especially inside the exterior material 1. Rising section 12
By using a sealing material having a high adhesion (adhesion) strength with respect to 1 or the groove-shaped space of the holding member 2, the water stopping performance can be maintained for a long period of time.

In the embodiment shown in FIG. 2, the outer rising portion 123 of the exterior material 1 is a substantially inclined piece without the engaging portion 24, and the upper holding member 2B is substantially flat. In this way, the shape and configuration of the outer rising portion 123 and the upper holding member 2B of the exterior material 1 are not limited to the configuration of the embodiment of FIG. 1, but how can it be performed without impairing the effects of the present invention. Is also good. Further, the lower holding member 2A and the upper holding member 2B are integrated by direct fixing rather than fitting, and a known attachment method may be adopted. Further, on the back surface side of the cover material 4 (upper surface of the upper holding member 2B), the backup material 5 for preventing the deformation of the cover material 4 is arranged. The backup material 5 is made of a resin foam material such as polyurethane, polystyrene, phenol, etc., glass wool, a fiber type molding material with wood wool, etc., and prevents deformation of the cover material 4, and also contributes to prevention of dew condensation and soundproofing. . Since the configuration other than the above is already described in the embodiment of FIG. 1, the same reference numerals are given to the drawings and the description thereof will be omitted. The procedure for constructing the exterior structure of the embodiment shown in FIG. 2 is almost the same as that of the embodiment shown in FIG. 1. First, as shown in FIG.
Attach the lower holding member 2A to the upper predetermined position, and then
As shown in (b), the exterior member 1 is attached to the lower holding member 2A.
2C, and subsequently, the upper holding member 2B is attached to the lower holding member 2A as shown in FIG. 2C, and then the backup material 5 and the cover material 4 are attached to obtain the exterior structure shown in FIG. 2D.

In the embodiment shown in FIG. 3, a holding member 2 made of a single member is used instead of a combination of a plurality of members as in the embodiments of FIGS. 1 and 2. This holding member 2
Has a bottom surface of a frame body having a substantially U-shaped cross section that is attached to the base 3.
1, and the water stop holding portions 22 are formed on the back surface sides of the wing piece portions that extend outward and downward from the left and right upper ends of the frame body portion,
A leg piece whose lower end faces (holds) the drain groove 122 of the exterior material 1 is formed inside the water stop holding portions 22 and 22, and a downward inclined piece is provided outside the water stop holding portions 22 and 22. Fitted portions 27, 27 for the cover material are formed. Further, the water-stopping holding portion 22 is formed by adhering an elastic water-stopping material having a rectangular cross section to the back surface of the wing piece portion with a double-sided tape or an adhesive. As described above, the holding member 2 does not limit the configuration other than the structure including the watertight holding portion 22 that presses the mounting portion 21 of the base 3 and the inner rising portion 121. Structures other than those described above have already been described in any of the embodiments shown in FIGS. 1 and 2, so the same reference numerals are given to the drawings and the description thereof will be omitted. The procedure for constructing the exterior structure of the embodiment shown in FIG. 3 is as follows. First, as shown in FIG. 3 (a), the exterior material 1 is arranged on the base 3, and then as shown in FIG. 3 (b). Holding member 2
Is attached at a predetermined position. At this time, the lower surface of the water blocking holding portion 22 is attached so as to press the top portion of the inner rising portion 121 of the exterior material 1. The arrangement position of the exterior material 1 is finely adjusted as needed. In this state, the outer rising portion 123 is along the outer surface of the frame body portion, and the wing piece portion faces the upper end thereof,
The lower end of the leg piece faces the drainage groove 122. Therefore, the reference numeral 28 of the pressing portion is attached to the upper end of the outer rising portion 123 and the lower end of the leg piece. After that, the backup material 5 and the cover material 4 are attached to obtain the exterior structure shown in FIG.

Each of the embodiments shown in FIGS. 4 to 8 is an example in which the upper holding member 2B also serves as a cover material. Structures other than those described below have already been described in any of the embodiments shown in FIGS. 1 to 3, so the same reference numerals are given to the drawings and the description thereof will be omitted.

In the embodiment shown in FIG. 4, the lower holding member 2A and the upper holding member 2B have substantially the same width and form a box-shaped combined state. Therefore, not only in the vertical direction, but also in the vertical direction.
Durable strength is high even with respect to the load from the direction of inclination close to the side. Further, an engaging portion 1231 is formed on the upper end of the outer rising portion 123 of the exterior material 1, and the engaged portion 24 that engages with the engaging portion 1231 is formed inside the rising portions 23, 23 of the lower holding member 2A. It is the upper end of the raised second standing portion. Further, the engaging portion 1231 formed on the upper end of the outer rising portion 123.
The upper holding member 2B holds (pressing portion 28) from above.

In the embodiment shown in FIG. 5, the engaged portion 24 that engages with the engaging portion 1231 formed at the upper end of the outer rising portion 123 of the exterior material 1 is the raised portions 23, 23 of the lower holding member 2A.
Is the upper end of. Also, the inner rising portion 12 of the drainage groove 122.
In the vicinity of 1, the lower end of the substantially vertical leg of the upper holding member 2B faces (holds from above). Further, on the side of the face plate portion 11 of the inner rising portion 121, a holding portion 29 formed in a hanging shape from the left and right ends of the upper holding member 2B faces, and the holding portion 29 and the substantially vertical leg piece sandwich the holding portion 29. The inner rising part 121 is protected.

In the embodiment shown in FIG. 6, an engaging portion 1231A and an engaging portion 1231B are formed in the middle of the height of the outer rising portion 123 of the exterior member 1, and the lower holding member 2 is provided.
It engages with the engaged parts 24A and 24B provided on the vertical piece of A. The engaged portion 24A also serves as the connection receiving portion 25,
The connecting portion 26 of the upper holding member 2B faces the outside of the engaging portion 1231A, and eventually the engaging portion 1231A is sandwiched between the engaging portions of the connecting receiving portion 25 and the connecting portion 26. In this manner, the exterior material 1 is attached to the holding member 2 or the lower holding member 2A by engaging or fitting the inner rising portion 121 and the outer rising portion 123, so that the water blocking holding portion 22 holds the inner rising portion 121 under pressure. A stable mounting strength can be obtained as compared with the case of only the above, but the mounting method is not limited to engagement and fitting, but may be directly fixed with a screw or the like, clamped and held as described above, or From the upper side or the side, the inner rising portion 121, the drain groove 122, and the outer rising portion 1
Any known means such as pressing and holding 23 or the like may be used, and a plurality of them may be combined.

In the embodiment shown in FIG. 7, the wrapping portion 29 formed in a hanging shape from the left and right ends of the upper holding member 2B faces the base end along the face plate portion 11 side of the inner rising portion 121 to wrap. The base end is pressed and held by the lower end (pressing part 28) of the holding part 29. That is, in the configuration in which the standing member 23 is provided on the holding member 2 or the lower holding member 2A, the inner rising portion 1 of the exterior material 1 is formed.
21 can be engaged with the upright portion 23 to ensure a stable upright state, but in the configuration in which the upright portion 23 is not provided, the substantially vertical leg piece in the embodiment of FIG. 5 and the embodiment of FIG. It is desirable to adopt a structure that prevents the inner rising portion 121 from being deformed like the holding portion 29 in FIG.

In the embodiment shown in FIG. 8, the standing portion 23 of the lower holding member 2A is formed by inclining it to the face plate portion 11 side of the exterior material 1, that is, the working width inward. The inner rising portion 121 of the material 1 is engaged,
As a result, the face plate portion 11 is deformed into a concave shape. In this case, the strength performance against the blowing wind pressure is improved, and the face plate portion 11
Is suppressed, and the concave shape of the face plate portion 11 makes the pocket wave phenomenon, which is most noticeable in normal times, invisible so that the design can be improved.

Further, in each of the embodiments shown in FIGS. 9 to 12,
Basically, the same rain proofing performance and strength performance can be obtained without using the cover material 4, but as a decorative material when the appearance of the extruded product made of aluminum or hard resin is disliked, or The cover material 4 is used as a protective material for preventing the direct water of the elastic water blocking material (22) from being exposed to direct sunlight when a hard resin extruded product is used as the holding members 2A and 2B.

The cover member 4 in each of the embodiments shown in FIGS. 9, 10, and 12 extends downward from the fitting portion 43 and extends to the face plate portion 1.
1 is provided with a hanging piece 44 that comes close to or in contact therewith, and the holding members 2A and 2B and the elastic water blocking material (22) located inside are visually completely hidden, and especially the same material as the exterior material 1. By using, the designability is improved. Further, since the irradiation and reflection of sunlight are prevented, it is possible to suppress the aging (deterioration) of the holding members 2A, 2B and the elastic water blocking material (22) located inside. The cover material 4 in the embodiment of FIG. 11 has the semi-arcuate lower end close to the face plate portion 11 in the same manner as the hanging piece 44, and thus exhibits the same effect as described above. Further, the cover material 4 is the same as in the embodiment of FIG.
As in the embodiment of FIG. 3, a backup material 5 may be provided inside to absorb the impact against the collision of a tree branch, a small stone, etc., and prevent deterioration of the design. You may make it contribute to the addition of a design property by itself.

The present invention has been described above based on the embodiments of the drawings, but the present invention is not limited to the above embodiments, and may be modified in any manner as long as the configuration described in the claims is not changed. It can be carried out.

In summary, according to the vertical-roofed exterior structure of the present invention, the inside rising portion of the exterior material laid on the substrate is pressed by the water retaining portion of the retaining member, and the gap into which rainwater enters enters the water retaining portion. Since it was blocked at, it will have excellent rain performance. Moreover, since the integrity of the exterior material and the holding member is improved, the strength performance is also excellent. Therefore, even if the holding member and the exterior material are temporarily elastically deformed by an external force such as strong wind, there is no gap for rainwater to enter, and during roll molding of the exterior material or extrusion molding of the retention member. Some of the formation errors and some construction errors can be absorbed by the water stop holding part, and water infiltration can be prevented.

Further, when the water-stopping holding portion of the holding member is formed by accommodating the elastic water-stopping material in the groove portion, the elastic water-stopping material may be displaced even if a large external force such as an earthquake occurs. And a stable structure is maintained. Further, an irregular shaped material such as a waste rubber material may be densely compressed and housed in the groove-shaped space to form a water-stop holding portion.

Further, when an engaging portion that elastically engages with an engaged portion formed in the holding member is formed on at least one of the upper end and the middle of the outer rising portion of the exterior material, gusts during construction (on the way) The safety against the like is increased.

Further, the holding member is provided with an upward standing portion,
When the standing portion and the inner rising portion of the exterior material are engaged with each other, the safety at the time of construction (on the way) is further enhanced in combination with the engagement between the engaging portion and the engaged portion, Further, it is possible to suppress displacement and deformation in the working width center direction of the exterior material when the load weight due to the windward wind pressure and the positive load action during heavy snowfall are applied. Furthermore, it is possible to prevent the plastic deformation of the structure outside the inner rising portion of the exterior material, and to stably maintain the rain-resisting and holding-related functions.
