Description

  TECHNICAL FIELD The present invention relates to a vertical exterior structure in which a cap material does not tilt to the left and right during strong wind action and does not cause rainwater to enter.

  The structure that prevents the invasion of rainwater into the side edge of the exterior material is widely used in various modes by raising the side edges of various types of vertical-type exterior materials and attaching a cap material so as to straddle between the side edges. It is being constructed.

For example, Patent Document 1 discloses a roof plate material 2 (= exterior material) in which an upper end of an upright portion 4 is bent inward and a lower end (lower end bent portion 6) thereof is folded back, and a substantially U-shape. The connecting member 8 (= cap material) having arc-shaped engaging portions (arc portions 10) formed at the left and right lower ends of the cover portion of the cover portion, the lower end bent portion 6 of the exterior material and the arc portion 10 of the cap material An engaged roofing sheet apparatus is disclosed.
In Patent Document 2, a rounded corner 8 is provided on the side edge of the metal roof plate 1 (= exterior material), and a standing goby 2 is provided at the upper end formed in a vertical shape. Disclosed is a metal tile roof that is engaged with the gouge stop portion 5 of the hanger 3 and is fitted so that the leg pieces of the cap-type metal tile rod 4 (= cap material) formed in a substantially Ω shape are brought into contact with the corner 8. Has been.
Japanese Patent No. 2566241 (FIG. 1) Utility Model Registration No. 2520259 (FIG. 1)

However, in the structure of Patent Document 1, the engagement position between the lower end bent portion 6 of the roof plate material 2 (= exterior material) and the arc portion 10 of the connecting material 8 (= cap material) is higher than the face plate portion of the external material. Because it is located, rainwater flowing through the face plate part when there is no wind is difficult to enter the back side of the cap material, but it is easy for the cap material to be tilted to the left and right. In addition, for example, when the cap material tilts when strong wind acts from the left and right direction, the leg piece on one side sinks and the leg piece on the other side rises, so that rainwater can easily enter from the leg piece on the raised side. was there.
Furthermore, in the structure of Patent Document 2, the leg pieces of the cap-type metal rod 4 (= cap material) are formed into a round shape, and the round-shaped corners 8 of the metal roof plate 1 (= exterior material) and the superposed shape are formed. For example, even when strong winds act from the left and right direction, the cap material is prevented from tilting left and right, but rainwater flowing through the face plate enters through the gap between the leg piece and the rising part by capillary action. There was a problem that it was easy to do.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to propose a vertical casing structure in which the cap material is not tilted to the left and right during strong wind action and does not cause rainwater to enter.

  The present invention has been proposed in view of the above, and is a vertical casing structure using a vertical casing having raised left and right side edges, and the vertical casing is provided on the left and right sides of the face plate portion. A side edge molding part with a raised edge is provided, the opposite side edge molding part of the adjacent vertical facing exterior material is attached to the base with a holding member, and the cap material is arranged so as to straddle the opposite side edge molding part And a retaining member, and a leg piece of the cap material is brought into contact with the face plate portion of the vertically wound exterior material, and a corner space is formed inside thereof. is there.

  Further, the present invention is characterized in that, in the vertical facing exterior structure, a concave groove is formed between the contact portion of the vertical facing exterior material and the side edge molding portion to enlarge the corner space. We also propose a vertical facing structure.

  Further, according to the present invention, in the vertical casing structure, a protruding portion is formed on a face plate portion of the vertical casing, and the protruding portion is in contact with a leg piece of the cap material at the protruding portion. A structure is also proposed.

  In the vertical casing structure of the present invention, the leg pieces of the cap material are in contact with the face plate portion of the vertical casing, and the corner space is formed on the inside (outside as the vertical casing), for example, Even if strong winds act from the left and right direction, the cap material does not tilt to the left and right because the left and right contact parts are in contact with the face plate part (grounding), and the capillarity action There is no infiltration of rainwater.

  In addition, in the case of a vertical casing structure in which a concave groove is formed between the contact part of the vertical casing and the side edge molding part and the corner space is enlarged, the infiltration of rainwater by capillary action is more reliably prevented. In addition, even if rainwater enters inside from the contact portion, it can be surely flowed down to the water side in the corner space.

  Furthermore, in the case of a vertical facing exterior structure in which a raised portion is formed on the face plate portion of the vertical facing exterior material and abuts against the leg piece of the cap material at the raised portion, rainwater flowing through the face plate portion falls under the raised portion. Since it flows down to the side, it is possible to prevent rainwater from collecting on the side edge.

  Each member of (A) vertical facing exterior material, (B) holding member, and (C) cap material used in the vertical facing exterior structure using the vertical facing exterior material with the left and right side edges raised according to the present invention will be described.

(A) Vertical facing exterior material The vertical facing exterior material is configured to include a side edge molding portion in which the left and right side edges of the face plate portion are raised, and this side edge molding portion is attached to the base by a holding member described later. As long as it can be formed, it may be appropriately formed according to the configuration of the holding member. For example, as shown in the illustrated embodiment described later, it may be a simple standing piece, and is not particularly limited.
In addition, the vertical covering material has a configuration in which a corner space is formed outside the abutting portion (inside as the cap material) in a state where a cap material described later is disposed. It may be formed appropriately according to the shape of the cap material to be described later. For example, it may be a right-angled corner as shown in the illustrated embodiment described later, and is not particularly limited.

  Furthermore, it is preferable that the vertical facing exterior material has a concave groove formed between a contact portion of the cap material described later and the side edge molding portion. This concave groove expands the corner space and does not particularly limit its shape.

  Further, it is preferable that the longitudinally-wrapped exterior material has a raised portion formed on the face plate portion, and is in contact with a leg piece of a cap material described later at the raised portion. The raised portion forms a concave flowing water portion through which rainwater flows, and can prevent the rainwater from concentrating from the raised portion to the side edge molding portion.

(B) Holding member A holding member attaches the side edge shaping | molding part which the said adjacent vertical facing exterior material made to oppose to a foundation | substrate, and is provided with the structure which engages the cap material mentioned later.
The configuration of “attaching the adjacent side edge molding portions of the adjacent vertical facing exterior materials to the base” means having both a fixing portion to the base and a holding portion for holding the side edge molding portion.
In addition, the “configuration in which the cap material is engaged” means that an engaged portion with respect to the engaging portion of the cap material is provided. That is, the holding member has a structure having a fixing portion to the base, a holding portion for holding the side edge molding portion, and an engaged portion for engaging the cap material. It may be constituted by members or may be constituted by combining a plurality of members.
Further, the holding member may be one that is preliminarily molded into a predetermined shape and fixed to the base, or as shown in the illustrated embodiment described later, the vertical covering material is faced to the holding member fixed to the base and then held. You may make it hold | maintain the side edge shaping | molding part of a vertical-wrapping exterior material by changing a part of member. In other words, the holding portion may be formed before the vertical covering material is disposed, or may be formed by being deformed after the vertical covering material is disposed.

  As the base for fixing the holding member, any building frame to which fixing tools such as nails, screws, anchors, etc. can be attached, such as wooden structures, steel structures, concrete structures, etc., can be used for heat insulation and other needs. It includes boards such as wood wool cement boards to be installed accordingly.

(C) Cap material The cap material is arranged so as to straddle the opposite side edge molding portions of the adjacent vertical facing exterior materials, and is engaged with the holding member. It contacts the face plate portion of the exterior material, and further, a corner space is formed inside the contact portion.
`` Arranged so as to straddle the side edge molding parts opposed to each other of the adjacent vertical facing exterior materials and engage with the holding member '' comprises a cover part that covers between the left and right side edge molding parts, This means that an engaging portion that is engaged with the engaged portion of the holding member is provided.
In addition, the configuration in which the left and right leg pieces abut against the face plate portion of the vertical covering material is a structure in which the left and right leg pieces (lower ends) abut against the face plate portion from above when the cap material is laid. It is to have a contact part. In particular, it is desirable to bring the contact portion into surface contact with the face plate portion of the vertical casing material in a plane. For example, when the contact part makes line contact with the face plate part, there is a risk that wind will blow into the gap where the contact part is slightly separated from the face plate part, causing an accident that blows off the cap material. This is because the strong wind from the side acts to hold down rather.
Further, the configuration that “the corner space is formed inside the abutting portion” is the same as that described in the section of (A) Longitudinal exterior material in the state where the cap material is disposed. A corner space is formed on the inner side of the contact portion (outer side as a vertical facing exterior material). And this corner space should just be formed suitably according to the shape of the said vertical covering exterior material, for example, as shown in the example of illustration mentioned later, it may be a simple inclined piece shape, and is not specifically limited.

  In the vertical casing structure of the present invention constructed from each of these members, the leg pieces of the cap material are in contact with the face plate portion of the vertical casing material, and the corner space is formed on the inside thereof. Even if a strong wind acts from the direction, the cap material does not tilt and come off to the right and left, and rainwater does not enter due to capillary action.

  FIG. 1 and, strictly speaking, FIGS. 1A and 1E show an example in which the present invention is applied to a vertical casing structure using a vertical-spreading vertical casing (hereinafter simply referred to as an outer casing) 1. Yes, each member (exterior material 1, holding member 2, cap material 3) in this example is shown in FIGS.

As shown in FIG. 1B, the exterior material 1 is a very simple structure in which the left and right side edges of a substantially horizontal face plate portion 11 are raised substantially vertically to form standing piece-shaped side edge molding portions 12 and 12. It is a simple configuration.
The exterior material 1 may be a continuous material in the flow direction, or may be a fixed-size exterior material connected using a known connecting structure, a surface-coated steel sheet, a laminated steel sheet, a plated steel sheet, a stainless steel sheet, aluminum. Molded from known metal materials such as alloy plates, titanium alloy plates, copper plates, brass plates, lead plates, etc., carbon fiber laminated plates, hard resin plates, etc., roll forming or press molding when the material is a metal plate, or It is molded (molded) by a combination of both. When the material is a non-metallic material, it is mainly molded by mold molding. The material thickness is not particularly limited, but is about 0.4 to 1.6 mm.

As shown in FIG. 1C, the holding member 2 includes a fixing portion 21 (22 is a fixing tool such as a screw) to the base 4 corresponding to a substantially L-shaped horizontal piece, and a vertical piece portion corresponding to a vertical piece. 23, holding portions 24, 24 that are provided at the upper end of the vertical piece portion 23 and hold the side edge forming portions 12, 12 of the exterior material 1, 1, and an engaged portion 25 for engaging the cap material 3. , 25.
The holding member 2 may be a short piece material or a long piece, which will be described in detail in FIG. 2 to be described later. However, the exterior member 1 faces the holding member 2 fixed to the base 4, After that, a part of the holding member 2 is deformed (= the holding part 24 is formed) to hold the side edge molding part 12 of the exterior material 1, and any material that can be deformed is particularly limited. Although it is not a thing, you may form with the raw material similar to the said exterior material 1, for example. Alternatively, when it is preliminarily molded into a predetermined shape, it may be formed from an extruded product made of aluminum or hard resin, a pressed product such as a plated steel plate or a stainless steel plate, and ceramic.
In addition, as the base 4, a plywood having a predetermined thickness was used on the surface of the field material.

As shown in FIG. 1 (d), the cap material 3 includes an inverted V-shaped covering portion 31 that covers the space between the left and right side edge molding portions 12 and 12, and the engaged portions 25 and 25 of the holding member 2. It is the structure which has the inward substantially square-shaped engaging parts 32 and 32 to engage, and the leg piece 33 of the left-right inclination piece shape in the installation state of the cap material 3. At the lower end of the leg piece 33, an abutting portion 331 that abuts against the face plate portion 11 of the exterior material 1 is formed, and this abutting portion 331 is a planar shape extending in the direction of the face plate portion 11 in the illustrated embodiment ( Surface part).
The cap material 3 may be a threading material that is continuous in the flow direction as in the case of the exterior material 1 or may be a fixed-size exterior material that is connected using a known connection structure. What is necessary is just to form with a raw material.
The exterior material 1 has the side edge of the face plate portion 11 raised substantially vertically to form the side edge molding portion 12, whereas the leg piece 33 of the cap material 3 is in the shape of an inclined piece. Between the members (1, 3), a corner space 34 is formed inside the abutting portion 331 which is the lower end of the leg piece 33 (outside as the exterior material 1). In addition, an indeterminate elastic material / water-stopping material 35 was disposed on the top inner surface of the cover portion 31 of the cap material 3. The elastic material / waterproof material 35 may be a simple elastic material or a simple waterstop material, but is preferably a material having both elasticity and water-stopping property, and may be of a fixed shape or an indeterminate shape.

Next, a procedure for constructing the member will be described.
First, the holding member 2 is disposed at a predetermined position on the base 4 and the fixing portion 21 is fixed by the fixing tool 22.
Subsequently, the exterior materials 1 and 1 are arranged on the left and right sides of the vertical piece portion 23 of the holding member 2 so that the side edge forming portions 12 and 12 face each other.
Then, the upper part of the vertical piece part 23 of the holding member 2 is bent, and the side edge molding parts 12 and 12 of the left and right exterior members 1 and 1 are held. That is, the holding portions 24 and 24 are formed.
Finally, the cap member 3 in which the elastic material / water-stopping material 35 is previously arranged on the inner surface of the top portion is disposed so as to straddle the opposed side edge molding portions 12 and 12, and the engaging portions 32 and 32 are arranged on the holding member 2. The lower end (planar contact portions 331, 331) of the leg pieces 33, 33 of the cap material 3 are brought into contact with the face plate portions 11, 11 of the exterior material 1, 1 by engaging with the engaged portions 25, 25 ( Surface contact). Corner spaces 34 and 34 are formed inside the contact portions 331 and 331.

In the vertical facing exterior structure of the present invention constructed from each of these members (the exterior material 1, the holding member 2, and the cap material 3), the leg piece 33 (contact portion 331) of the cap material 3 is the face plate portion of the exterior material 1. 11, even if a strong wind acts from the left and right direction, for example, the state where the left and right contact portions 331 are stably in contact (grounded) with the face plate portion 11 is maintained, and the cap material 3 is tilted left and right. Not even that. In particular, the contact portion 331 in the illustrated embodiment has a surface shape (surface portion) extending in the direction of the face plate portion 11, and the surface contact portion 331 and the face plate portion 11 are in surface contact with each other. Even if the wind blows, rather, the strong wind acts to press downward, and the blowing of the wind into the cap member 3 does not occur, and a stable engagement state is maintained. For example, if the lower end of the cap material is only in line contact with the face plate part, either the left or right contact part is slightly lifted from the face plate part and the wind blows into the gap and is provided inside. Rather, the space may catch the wind and cause an accident that blows off the cap material.
Further, since the corner space 34 is formed inside the contact portion 331 (outside as the exterior material 1), rainwater does not enter inside the contact portion 331 due to capillary action. Even if rainwater enters the partial space 34, the corner space 34 flows down to the lower side.

  In the illustrated embodiment, the elastic material / water-stopping material 35 is disposed on the top inner surface of the cap material 3, so that the upper ends of the holding portions 24, 24 of the holding member 2 are pressed to the upper end of the side edge molding portion of the exterior material 1. In addition to fulfilling the pressing action, the engagement between the engagement portions 32 and 32 (with the engaged portion 25 of the holding member 2) becomes stronger.

2 is substantially the same as the holding member 2 in FIG. 1, and a substantially L-shaped horizontal piece is a fixed portion 21 and a vertical portion. The piece is a vertical piece portion 23, and the fixing portion 21 is provided with a hole 211 through which a fixing tool 22 such as a screw is inserted in the approximate center in the length direction. The upper portion of the vertical piece portion 23 is divided into two at substantially the center in the length direction, and the cross-section is processed into a continuous round wave shape. The round wave portion is denoted by reference numeral 204, and is substantially formed on the side edge of the round wave portion 204. A triangular fold 205 is provided. The upper portion of the vertical piece portion 23 is bent in different directions as shown by a dotted arrow in FIG.
FIGS. 2E and 2F are enlarged cross-sectional views showing a situation in which the round wave portion 204 and the folded portion 205 are bent to form the holding portion 24 and the engaged portion 25, respectively. The material 1 ′ will be described in detail in an example of FIG. 3 described later.

In FIG. 2E, the holding member 20 ′ shown in FIGS. 2A to 2C is arranged and fixed at a predetermined position on the base 4, and then exterior materials 1 ′ and 1 ′ are placed on the left and right. In this state, the side edge forming portions 12 and 12 are opposed to each other. The dotted line arrows in the figure indicate the direction in which the round wave portion 204 of the holding member 20 ′ is bent. As described above, one of the round wave portions 204 divided into two is leftward and the other is rightward. The state bent to the side is FIG. 2 (f).
In FIG. 2 (f), the bent round wave portions 204, 204 (holding portions 24, 24) hold the side edge molding portions 12, 12 of the left and right exterior members 1, 1 in a pressed form from the outside. The folding portions 205 and 205 may be bent outward in advance, and become engaged portions 25 and 25 as the round wave portions 204 and 204 are bent.

  Since the holding portion 24 is formed by the round wave portion 204 which has been processed into a continuous round wave shape in this way, a plurality of arc-shaped protruding portions are pressed from the outside to the side surface forming portion 12 which is a flat plate-like vertical surface. Therefore, a stable holding state can be obtained. On the other hand, for example, when the holding part 24 is a simple flat plate-like piece, it is necessary that the flat side molding part 12 and the engaged part 24 are in contact with each other. Sufficient holding cannot be obtained only by slightly tilting or deforming.

  FIG. 3 is an embodiment showing a vertical facing exterior structure in which the exterior material 1 ′ also used in FIGS. 2 (e) and 2 (f) is an exterior surface. The exterior material 1 ′ Concave grooves 13 and 13 that are recessed downward are provided at the end portions, that is, the base ends of the side surface molding portions 12, and further, protruding portions 14 and 14 that are upwardly protruded are provided on the outer sides. The 3 ′ abutting portion 331 ′ abuts, and the rest of the configuration is substantially the same as the member in the embodiment of FIG.

In this embodiment, since the concave groove 13 is formed as described above, the corner space 34 ′ is larger than the corner space 34 when the concave groove 13 in the embodiment of FIG. 1 is not formed. ing.
Therefore, in this embodiment, it is possible to more reliably prevent rainwater from entering due to capillary action, and even if rainwater enters inside from the abutting portion 331 ′, the corner space 34 ′ can be submerged. Can flow down more reliably.
Further, the contact portion 331 ′ of the cap material 3 ′ has a shape (wider surface shape, wider surface portion) that extends longer in the direction of the face plate portion 11 than the contact portion 331 in the embodiment of FIG. As in the embodiment of FIG. 1, even if strong wind blows from the side, rather, the strong wind acts to hold down downward, and no blowing of wind into the cap material 3 ′ occurs. A stable engagement state is maintained. Further, as in the embodiment of FIG. 1, the inside of the corner space 34 'is not in a reduced pressure state, and rainwater is not led into the interior.

Further, in this embodiment, since the raised portion 14 is formed and abutted against the abutting portion 331 ′ as described above, the inside of the raised portion 14 of the face plate portion 11 (running water portion 15) is positioned at a lower level. Then, rainwater flows down this part. In the illustrated embodiment, since the second raised portion 14 ′ is also provided in the approximate center of the face plate portion 11, the flowing water portion 15 is between the raised portion 14 and the second raised portion 14 ′.
Therefore, in this embodiment, the rainwater flowing through the face plate portion 11 flows down the flowing water portion 15 to the lower side, so that the rainwater can be prevented from collecting on the side edge.
