Description

  The present invention makes it possible to quickly and inexpensively finish an exterior structure in which the connecting portion in the longitudinal direction is formed in a flat shape, and further to ensure the rain performance of the connecting portion. It is related with thatched exterior structure.

Conventionally, several structures have been proposed as a connecting structure for the horizontal covering material (for example, Patent Documents 1, 2, and 3).
In Patent Document 1, a separate drain piece is caulked and integrated with one side edge of the exterior material, and the protrusion of the other side edge of the adjacent exterior material is interposed between the side edge and the drain piece. A structure for inserting and connecting pieces is disclosed. However, in this structure, the connecting portion of the exterior material after construction is formed with a difference in level, which is not preferable in terms of aesthetics (design). Moreover, since the operation | work which produces a draining piece as a different body, the operation | work which crimps and fits the produced draining piece to the one side edge of an exterior | packing material, etc. are needed, manufacturing cost was a high thing.

  Patent Document 2 discloses a structure in which an upward folded edge formed on one side edge and a downward folded edge formed on the other side edge are engaged and connected, and a connecting portion of an exterior material after construction is disclosed. Is formed in a substantially flat shape. However, in this structure, although the face plate part of the exterior material itself is arranged in a polymerized state, the water-side molding parts are located adjacent to each other, and a gap is inevitably generated to become a rainwater infiltration portion. In addition, the exterior material has a structure in which folded parts are formed at the edges in both the short and long directions, so the molding speed cannot be increased, resulting in an inevitable increase in manufacturing cost. Met.

Further, Patent Document 3 describes a roofing material in which a polymerized portion (a discarded plate portion 14) having an angular wave cross section is provided at an end portion in a longitudinal direction. However, in such a configuration, although the face plate portion itself of the roof plate is arranged in a superposed manner, the eaves-side molded portions are positioned adjacent to each other, and a gap is inevitably generated to become a rainwater infiltration portion. In addition, it is necessary to form the end in the longitudinal direction in a pressing process after roll forming the eaves ridge-side molded portion (female-side fitting portion 15, male-side fitting portion 16) at the end portion in the short direction. Therefore, the molding speed could not be increased.

  Therefore, the present invention can quickly and inexpensively finish the exterior structure in which the connecting portion in the longitudinal direction is formed in a flat shape, and further provides a connection in the longitudinal direction that can ensure the rain performance of the connecting portion. An object of the present invention is to provide a side covering material and a side covering structure that can be easily and reliably implemented.

The present invention has been proposed in view of the above. From the eaves edge in the short direction, a folded piece obtained by bending the edge of the face plate portion downward, and a horizontal piece whose lower end extends to the ridge side. Forming a water-side molded part, and forming a water-side molded part connected to the water-side molded part by engagement or fitting on the ridge edge, and in a longitudinal direction by blanking A connecting portion having one or more convex portions at one end edge, a connection receiving portion having an insertion hole into which the convex portion can be inserted at the other end edge, and one convex portion and the other inserting hole. And a notch extending in the roll forming direction at one edge in the longitudinal direction, only the folded piece of the underwater forming part, or only the horizontal piece. , or provided so as to extend in both, horizontal roofing exterior of Underwater side molding section cutout portion is formed, longitudinally adjacent It relates lateral roofing sheathing material, characterized in that connected to disposing of the water lower molding portion.
In addition, the edge of a transversal direction is a side edge along a longitudinal direction, and the edge of a longitudinal direction is a side edge along a transversal direction.

In the lateral covering material, it is desirable that the notch is provided at the boundary between the folded piece and the horizontal piece .
The insertion of the convex part means that the convex part is positioned on the back side if the counterpart is a concave part, and the convex part is inserted and positioned on the back side if it is an insertion hole. Means that.

In the present invention, the lateral covering material is connected to the lateral covering material adjacent in the short direction to the edge in the short direction, and a notch provided at the end in the length direction is formed. Among the formed water-side molded parts , the face plate part side from the notch part is positioned on the back surface of the face plate part of the water-side molded part adjacent to the longitudinal direction, and the horizontal part side is adjacent from the notch part. It also proposes a side-facing exterior structure characterized by being connected in combination with the other edge so that the notch becomes a fulcrum by positioning it on the back surface of the horizontal part of the underwater molding part is there.

Since the horizontal covering material of the present invention is produced by blanking and roll forming, it basically does not require press forming of the end portion, so that the speed of roll forming can be increased and the manufacturing cost can be reduced.
In addition, by providing a notched part in the underwater molding part at one end edge in the longitudinal direction by blanking, the end part of the underwater molding part is elastically deformed at the time of construction so that the side wall exterior is adjacent in the longitudinal direction. Since it can arrange | position so that it may insert in the underwater side molding part of material, the exterior structure in which rain performance can be ensured can be provided.

  In addition, when the notch is provided at the boundary between the hanging piece and the folded piece, it can be easily elastically deformed at the time of insertion (insertion) at the time of construction. Since it is located on the eaves side, it is desirable for rain performance.

  Further, the exterior material has a connection receiving portion having an insertion hole into which one or more convex portions can be inserted at one end edge in the longitudinal direction and the convex portion can be inserted into the other end edge by blank processing. Are provided so that one convex portion and the other insertion hole are in the same direction in the short direction, so that lifting of the edges of each other can be prevented without using an adhesive or the like. In other words, if one edge is simply overlapped with the other edge, the edge will be lifted, so it must be joined with an adhesive or the like. It is necessary to partially excise the backing material on the back side. However, by forming the connection portion and the connection receiving portion by blanking as described above, the connection is made so that the convex portion is inserted into the insertion hole when connecting in the longitudinal direction. It prevents the edges from lifting and eliminates the need to cut the backing material.

  Further, the side-facing exterior structure of the present invention produces the side-facing exterior material, which is the main component of the side-facing exterior structure, by blanking and roll forming as described above, so that the manufacturing cost can be reduced and the conventional exterior It does not require all joint members such as cover, end holding member (joiner), discard plate (drainage plate) like connection of materials, but is necessary for cover, end holding member (joiner), etc. Therefore, the number of members for construction can be reduced, and the overall construction cost can be greatly reduced.

  Forming a polymerization molding part by roll forming at the edge in the short direction, and connecting the uneven part in plan view having one or more convex parts at both ends in the longitudinal direction by blanking at the other edge A connection receiving portion having an insertion hole into which the convex portion can be inserted is provided so that one convex portion and the other insertion hole are in the same direction in the short direction.

A side facing exterior material (hereinafter simply referred to as an exterior material) 1 according to the present invention is an exterior material in which a polymerization molded portion is formed on an edge in a short direction as described above. A cutout 123 extending in the roll forming direction is formed in the underwater forming portion 12 at the end edge.
In the illustrated embodiment, the short direction refers to the water flow direction (eave building direction), and the long direction refers to the left-right direction (shift direction).

In the embodiment shown in FIGS. 1 and 2, the superposed molded part formed at the edge in the short (eave ridge) direction is the underwater molded part 12 provided at the eave end of the face plate part 11, the ridge of the face plate part 11. It refers to the water-side molded part 13 provided at the end.
The polymerization molded portion in the present invention is not particularly limited as long as it is connected by engagement or fitting, and more specifically, a part thereof is combined in a polymerization state in the connection state and engaged. Or it is what is fitted. Therefore, the water-side molding part 12 and the water-side molding part 13 are in accordance with it.
The underwater side molding portion 12 of the illustrated embodiment includes a folded piece 121 obtained by bending the eaves edge of the face plate portion 11 downward in a substantially vertical shape, and a lower end thereof bent toward the ridge side so as to extend substantially horizontally. And a horizontal piece 122 having its tip folded back to the back side.
Further, the water-side molded part 13 extends by bending and bending the edge of the face plate part 11 toward the surface side so as to be bent and extending toward the front side, and by bending the edge of the eaves toward the ridge side. The upper end of the ridge facing piece 132 is gently bent upward.

  And the notch part 123 in this invention is provided in the water-side molding part 12 of one edge of a longitudinal direction so that it may extend in a roll molding direction by blank processing, Comprising: Especially the shape etc. Although it does not limit about, it forms mainly in slit shape, such as a rectangular shape or a taper shape. The notch 123 has a concave shape as shown in FIG. 1 (a) after blanking performed prior to roll molding, but the slit is formed when the underwater molding portion 12 is molded by roll molding. It becomes the notch part 123, such as a shape. The notch 123 may be provided only on the folded piece 121 or may be provided only on the folded horizontal piece 122 and may extend over both, but it is easily elastically deformed when inserted (inserted) during construction. Therefore, it is desirable to provide it at a position across the boundary part. Moreover, since the notch part 123 provided in this position will be located in the eaves side most in the underwater side molding part 12, it is desirable also regarding rain performance.

The other configuration of the exterior material 1 is not particularly limited. For example, the edge in the longitudinal direction may be a non-molded flat plate shape. However, as shown in FIGS. The connection parts 14 and 15 having an uneven shape in plan view having one or more convex parts 14A and 15A at both end edges (hereinafter, one is referred to as a connection part 14 and the other as a connection receiving part 15 for convenience) The convex portions 14A and 15A and the other concave portions 15B and 14B are provided so as to be isotopic in the short direction (hereinafter referred to as a first mode), or one or more convex portions 14A at one edge. The connecting portion 14 having the insertion hole 15C into which the convex portion can be inserted into the other end edge, and the one convex portion 14A and the other insertion hole 15C are isolating in the short direction. (Hereinafter referred to as the second aspect) It is desirable.
The connection part 14 and the connection receiving part 15 in the first aspect are not particularly limited with respect to the shape and the like, as long as the connection part 14 and the connection receiving part 15 have an uneven shape in plan view having one or more convex parts 14A and 15A as described above. . Moreover, the connection receiving part 15 in the said 2nd aspect should just have the insertion hole 15C in which the said convex-shaped part 14A can be inserted as mentioned above, and it does not specifically limit about the shape. Although these connection part 14 and the connection receiving part 15 are formed in the edge of the longitudinal direction of the exterior material 1 by blanking, you may form one part by press molding.

In the illustrated embodiment, three substantially rectangular convex portions 14A and two concave portions are formed in one of the connecting portions 14 in the longitudinal direction (left side in the drawing) by blanking, and the other (right side in the drawing) is connected. The receiving portion 15 includes two substantially rectangular convex portions 15A and three concave portions 15B. The convex portion 14A and the concave portion 15B, and the concave portion 14B and the convex portion 15A are: Each is provided in the same direction in the short direction. In addition, each of the convex portions 14 </ b> A and 15 </ b> A is provided via a step portion 16. Therefore, each convex-shaped part 14A, 15A is a substantially flat shape located in the back surface side by the step part 16 with respect to the faceplate part 11. FIG. Further, the connection portion 14 and the connection receiving portion 15 have a configuration in which the ridge facing piece 132 of the water-side molding portion 13 is omitted. That is, it is a configuration in which a portion that becomes a folded portion of the water-side molded portion 13 at both end edges in the longitudinal direction is omitted.
In the description of the illustrated embodiment, the end on the left side of the drawing is described as one side and the connection portion 14, and the end on the right side of the drawing is described as the other side and the connection receiving portion 15. When connecting 1 and 1, one side is the insertion side (the side entering the inside), that is, one end is the edge on the side where the notch 123 is formed.

The procedure for creating the exterior material 1 of the illustrated embodiment will be described below.
First, the metal material of the exterior material 1 is typically about 0.4 to 1.6 mm of galvanized steel plate, galvanium steel plate, etc., rust-proof steel plate, special steel, non-ferrous metal, stainless steel plate, weather resistance Steel plates, copper plates, aluminum alloy plates, lead plates, zinc plates, titanium plates, and the like, are not particularly limited thereto. These are supplied in an almost coiled form. In addition, backing materials such as polyethylene foam and glass wool sheets may be attached to the back surface of these various long coil-shaped metal materials as necessary for the purpose of preventing condensation, soundproofing and fireproofing. .
A metal material having a predetermined width and a predetermined length is prepared by cutting the various long coil-shaped metal materials, and this is used as a molding material.
The molding material is subjected to blanking at both end edges in the longitudinal direction (by subsequent roll molding) so that the connection portion 14 and the connection receiving portion 15 having the above-described configuration are formed. In addition, you may make it perform these blank processes to each edge, respectively, and each convex part of the connection part 14 and the connection receiving part 15 and the convex part of the other party are isotopic in the transversal direction. Therefore, it may be formed by one zigzag cutting.

  Next, the molding material subjected to the blanking process is applied to a roll forming machine, in which case the forming material is applied to the forming machine in the direction indicated by the white arrow on the drawing. In the roll forming machine, bending is performed along the two-dot chain line shown in the figure. And the waterside shaping | molding part 12 of the said structure is formed in the eaves edge of the faceplate part 11, and the waterside shaping | molding part 13 of the said structure is formed in a ridge edge by roll forming.

  Since the exterior material 1 manufactured by the above-described procedure is produced by blanking and roll forming, it basically does not require press molding of the edge in the longitudinal direction, so that the speed of roll forming can be increased. Manufacturing cost can be reduced. The step 16 and the like may be formed by press molding.

A method for connecting the exterior material 1 in the longitudinal direction will be described.
As shown in FIG. 2 (a), when connecting the left end connecting portion 14 of the exterior material 1 arranged on the right side to the right end connection receiving portion 15 of the exterior material 1 already arranged on the left side, As the step, the end of the underwater molding portion 12 in which the notch 123 of the connection portion 14 of the right exterior material 1 is formed is elastically deformed, and the water of the connection receiving portion 15 of the left exterior material 1 is Insert into the lower molding part 12. More specifically, the right exterior material 1 faces the connection receiving portion 15 arranged in the eaves ridge direction of the left exterior material 1 so that the connection portion 14 is inclined, and a notch 123 is formed. In addition, the end of the underwater molding portion 12 (and the succeeding convex portion 14A on the most eaves side) is not completely inserted, but only the edge of the eaves is inserted.
Next, as a second step, the right exterior member 1 is rotated counterclockwise with the portion inserted in the first step as a fulcrum F. At that time, the right exterior material 1 can be easily carried out without requiring a large number of people because the convex portion 14A has a substantially flat shape and may be rotated in a state of being placed on the ground.
And as a 3rd process, except the edge part of the underwater shaping | molding part 12 in which the notch part 123 was formed, and the convex part 14A of the most eaves side following this edge part, it inserts and connects to the concave part 15B sequentially. . In this embodiment, the convex portion 15A is provided not only in the connection portion 14 but also in the connection receiving portion 15, so that the convex portions 14A and 15A are arranged along the back side of the concave portions 15B and 14B. And is connected to form a substantially flat exterior surface as shown in FIG.

When connecting exterior materials 1 and 1 adjacent to each other in the short-side (eave building) direction, it is exactly the same as a conventional lateral exterior material, and as shown in FIGS. 1 (b) and 3 (c) A well-known nail suitable for an exterior base is formed by engaging and connecting the water-side molding part 12 and the water-side molding part 13 of the exterior materials 1 and 1 adjacent in the tower direction. Fix it with a fastener (not shown) such as screw or screw.
Since the exterior material 1 of this illustrated embodiment is sequentially laid from the eave side to the ridge side, the exterior material 1 has already been laid on the eave side when connecting in the longitudinal (girder) direction as described above. . Therefore, after laying the left exterior material 1 so that the underwater molding part 12 is engaged with the waterside molding part 13 of the eaves side exterior material 1 that has already been laid, The right exterior packaging material 1 is connected by the three steps. At that time, the right exterior packaging material 1 is connected to the water-side molding part 13 of the eaves-side packaging material 1 already laid. While engaging the right end, as described above, the eaves edge of the convex portion 14A on the most eaves side of the connecting portion 14 is changed to the eaves edge of the concave portion 15B on the most eaves side of the connection receiving portion 15 of the left exterior member 1. Plug in.
The connection positions in the longitudinal (carrying) direction may be aligned, but in general, they are phased in stages so that they do not become the same as the connection of the exterior materials adjacent in the eaves direction. Is preferred.

  As described above, the exterior material 1 of the illustrated embodiment can easily and reliably perform the connection in the longitudinal direction during the connection construction, and the connection portion of the exterior material after construction can be constructed in a substantially flat shape. In the illustrated embodiment, since the exterior material 1 is rotated at the fulcrum F, the possibility of scratching is low, and since the convex portion 14A is substantially flat, the rotation operation is placed on the base material. Since it can be carried out in a state where the convex portion 14A is not deformed, it can be carried out easily. On the other hand, for example, when one exterior material is slid from the eave side to the ridge side and connected, as in the conventional method described above, or slid in the girder direction and connected, it rubs against the exterior material (metal material). There was a risk of scratching and causing corrosion.

Further, when the convex portions 14A and 15A are provided via the stepped portion 16 as in the illustrated embodiment, the portions along the back surface of the other concave portions 15B and 14B in the connection structure are parallel, It will be in the state which adjoined or contacted the back surface, and distortion will not arise in the base end of convex-shaped part 14A, 15A. That is, the convex portions 14A and 15A provided via the step portion 16 are located on the back side of the other side face plate portion 11 by the amount of the step portion 16, so that the convex portions 14A and 15A are engaged with each other. If there is no step 16 to be inserted into the back surface of the concave portions 15B, 14B, it is assumed that the convex portions 14A, 15A located on the back surface on the other side may be arranged in an inclined shape descending toward the tip. The On the other hand, when the step portion 16 is provided, the convex portions 14A and 15A having a uniform length are in close contact with or in contact with the back surface on the other side by the amount corresponding to the step portion 16. Further, the base ends of the convex portions 14A and 15A are not distorted, the exterior (connection) surface is substantially flat, and the connection structure with excellent design can be formed without exposing the cut surface. In addition, since the unevenness is appropriately engaged by the step portion 16, workability is improved.
In addition, for example, in the case where one end edge is overlapped with the other end edge, depending on the joining of the overlap margin portion, the overlap margin also requires an appropriate width. Since the insertion piece is polymerized so as to be inserted into the insertion hole of the connection receiving portion, its width (length) may be shorter than the above-mentioned polymerization allowance, reducing the amount of raw materials used and contributing to the reduction of manufacturing costs. To be.
Note that the number of the step portions 16 is not limited to one, and a plurality of step portions 16 may be provided (the effect of providing a plurality of step portions will be described in the embodiment of FIG. 4 described later).

Further, the connection in the longitudinal (carrying) direction of the exterior material 1 does not require a cover and an end holding member (joiner) unlike the connection of a conventional exterior material, and is shown in FIG. Thus, it can be constructed only by arranging the discard plate 2 on the back side. Furthermore, since the manufacturing cost of the exterior material 1 can be reduced, the overall construction cost can be kept low.
As shown in FIG. 3, the discard plate 2 includes folded portions 22 and 22 in which the left and right side edges of the rectangular flat plate portion 21 are folded back to the surface side, and a water return portion 23 in which the ridge edge of the flat plate portion 21 is folded back to the surface side. Further, an eaves side engagement portion 24 is provided which is formed inside and folded back toward the back surface side so as to be located inside the underwater molding portion 12 of the exterior material 1.
Therefore, rainwater or the like that has entered from the connecting portion in the longitudinal direction is guided onto the discard plate 2 and can flow down onto the face plate portion 11 of the lower packaging material 1.

  In the embodiment shown in FIG. 4, four substantially rectangular convex portions 14 </ b> A (two of which are two in the longitudinal direction) (on the left end portion of the exterior material located on the right side of the drawing) are formed by blanking. A convex portion serving as an insertion piece to be inserted into the insertion hole 15C (indicated by 14A 'in the drawing) and three concave portions 14B are formed, and the other (right end located on the left side of the drawing) is a connection receiving portion. 15 is a case where two substantially rectangular insertion holes 15C and two concave portions 15B are formed, and two convex portions 14A and concave portions 15B, and two convex portions 14A ′ which are insertion pieces. The insertion holes 15C are provided in the same direction in the short direction.

Further, in this embodiment, the connection portion 14 and the connection receiving portion 15 are each configured to have two step portions 16, and in this case, the following construction work is performed. In addition, the step part 16 is described as the first step and the second step from the face plate part 11 side.
As shown in FIG. 4B, the end of the underwater molding portion 12 in which the cutout portion 123 of the outer packaging material 1 to be rotated is formed and the convex portion 14A on the most eave side following the end have already been fixed. It inserts in the eaves edge of the concave part 15B in the inside of the underwater side molding part 12 of the left exterior material 1, and the eaves side.
At this time, the eave end of the second step portion 16 of the second convex portion (insertion piece) 14A ′ from the eave side of the connection portion 14 contacts the eave end of the insertion hole 15C on the most eave side of the connection receiving portion 15. (This portion is indicated as a restriction portion E1 in the drawing). Therefore, the tip of the second step portion 16 of the second convex portion (insertion piece) 14A ′ from the eave side is rotated while maintaining the state of being locked in the insertion hole 15C, and the right side The outer packaging material 1 can be rotated without shifting to the eaves side.
In this way, by providing a plurality of step portions 16, insertion into an appropriate location is facilitated, the right exterior material 1 can be stably rotated, and workability is improved.

  In the embodiment in which the insertion hole 15C is formed as in the embodiment of FIG. 4, the connection receiving portion 15 is not provided with the reference numeral 15A as a convex portion in the drawing, but two insertion holes 15C are formed. It can also be regarded as a configuration having a large convex portion. This is the case, for example, when the two convex portions 15A of the connection receiving portion 15 in the embodiment of FIG. 1 are connected in the lateral direction except for a part (becomes the insertion holes 15) (although the number of insertion holes is different). It is also clear from the fact that it is almost the same as the connection receiving portion 15 of FIG. That is, this embodiment is nothing but the one in which convex portions are formed on both side edges in the longitudinal direction and engaged with each other as in the embodiment of FIGS. Therefore, also in this embodiment, the large convex portion in which the two insertion holes 15C are formed is configured to be inserted into the back surface of the concave portion 14B of the connection portion 14.
