Description

The present invention relates to an exterior structure capable of reliably fixing an upper portion of water on a support member in which an exterior material such as a rhombus exterior material is arranged at equal intervals on a base.

In general, flat roofing is a construction method in which relatively small units of exterior materials are layered and roofed. It can be constructed with ordinary sheet metal tools, and is widely applied to an extremely wide variety of roofs. For example, wooden buildings such as shrines, temples, and houses. It is widely applied mainly to the roof of the house. The rhombus belonging to this flat roof has a design that the exterior material has a rhombus shape, and most of the dew condensation generated on the back surface side can be discharged and flowed down to the front surface side of the roofing material on the underwater side. It also has the structural advantage that the influence of moisture on the base material is small.

As a structure related to such rhombus, for example, the structures described in Patent Documents 1 and 2 are known.
Patent Document 1 describes a structure in which the hypotenuse (engagement receiving portions 12, 12A) on the water side of one exterior material (metal face material 11) is fixed by a plurality of suspenders (18). FIG. 7). And although not shown, the hanger (18) is fixed to the field board. The top of the water upper tip of the exterior material is folded. Further, when laying such a planar exterior material, a method is adopted in which marking is performed on the base and the top of the facing material is sequentially fixed with respect to the marking line. There is.
Patent Document 2 describes a structure in which the top of the water upper tip of the exterior material (thatched building board A) is fixed by a hanger (D) (FIG. 18). Then, as shown in FIGS. 19 and 20, the hanger (D) is fixed to the field board via (penetrating) the base material (C).

Jikken No. 7-11219 (Fig. 7) Japanese Unexamined Patent Publication No. 2-128049 (FIGS. 18 to 20)

However, in the structure of Patent Document 1, although the hypotenuse on the water side is fixed by two suspenders, the fixing points cannot be made uniform, and the negative pressure strength of the exterior material may vary. .. Therefore, marking is performed on the base, and the top of the roofing material is sequentially fixed so as to be positioned with respect to the "line". Therefore, when the engagement receiving portion is fixed with a plurality of hanging members, marking is performed. It is necessary to lock and fix the hanger in the direction of intersection with the wire, and the work of fixing while holding the hanger so as not to cause a deviation is extremely time-consuming. Further, in addition to the positioning as the exterior material, it is also necessary to position the hanger, which is very laborious.
To fix the hanger, it is necessary to position it in two ways: the position with respect to the hypotenuse (where the tip of the hanger hooks on the hypotenuse) and the position to fix it to the field material (where to hit the screw). If it is pulled too much, the hypotenuse will be deformed and the exterior material will be misaligned, and if it is loose, the strength will be insufficient.

Further, in the structure of Patent Document 2, although the position where the hanger is fixed is specified with respect to Patent Document 1, the tightening (depth) of screws or the like at the fixing position is not stable. In addition, since it is fixed to the field material (control panel: plywood), the pull-out strength of the screw is insufficient. Further, when the field material is a synthetic resin heat insulating material, there is a risk of fire spreading or collapse in the event of a fire.

Therefore, the present invention proposes an exterior structure capable of reliably fixing the water upper top portion on a support member in which an exterior material such as a rhombus exterior material is arranged at equal intervals on the base. The purpose is.

The present invention has been proposed in view of the above, and has two sides forming an obtuse angle located at the top of the water surface on a base having a plurality of support members arranged at equal intervals along the flow direction. Using an exterior material that is bent toward the front surface to form the engaged portion, and the two sides that form an obtuse angle located at the opposite top under the water are bent toward the back surface to form the engaged portion. In an exterior structure laid so that adjacent exterior materials engage with each other, the exterior materials have a substantially rectangular shape with two pairs of opposing internal angles having the same internal angle, and a short diagonal line connecting the two obtuse angles is a support member. The obtuse angle located at the water upper top of the exterior material is attached on the support member so that the long diagonal line connecting the two acute angles has a length that straddles at least the distance between the two adjacent support members. It proposes an exterior structure characterized by this. In the following description, a horizontally long rhombus-shaped exterior material having an obtuse angle located on the upper top of the water will be referred to as a "horizontal" type exterior material.
Further, in the present invention, a plurality of support members are arranged at equal intervals so as to be orthogonal to the flow direction, and two sides forming an acute angle located at the top of the water surface are bent toward the surface side to cover the base. Adjacent exterior materials are mutually formed by using an exterior material in which the engaging portion is formed and the engaging portion is formed by bending the two sides forming an acute angle located at the opposite top under the water to the back surface side. In the exterior structure laid so as to engage, the exterior material has a substantially rectangular shape in which two pairs of opposing internal angles have the same internal angle, and a short diagonal line connecting the two obtuse angles is arranged substantially parallel to the support member. An exterior structure characterized in that a long diagonal line connecting two acute angles has a length that straddles at least the distance between two adjacent support members, and an acute angle located at the upper water top of the exterior material is mounted on the support member. Is also proposed. In the following description, a vertically long rhombus-shaped exterior material having an acute angle located on the upper top of the water will be referred to as a "vertical installation" type exterior material.

The "short diagonal line connecting two obtuse angles" is nothing but a short diagonal line formed with two obtuse angles as end edges, and the "long diagonal line connecting two acute angles" has two acute angles as end edges. It is nothing but a "long diagonal line to be formed" and is formed in a rhombus shape, but does not include a substantially square shape like the exterior material in Patent Documents 1 and 2.
Further, the "length straddling the distance between two adjacent support members" means that the length is twice the length of the arrangement distance of the support members which is "equally spaced".
Further, "substantially rhombic shape", but refers to schematic planar shape of the face plate portion is rhombus-shaped, strictly the inclusion of fine edges and Guests folded Dari trim the tip of the example sharp corners Means that it also includes shapes that are hexagonal or octagonal.

Further, in the present invention, a "horizontal" type (horizontally elongated rhombus) exterior material in which an acute angle is located at the top of the water upper surface is used as a base in which a plurality of support members are arranged at equal intervals along the flow direction. For the base material in which a plurality of support members are arranged at equal intervals so as to be orthogonal to the flow direction, a "vertical" type (vertical rhombus) exterior material having an acute angle located at the top of the water is used. In an exterior structure in which adjacent exterior materials are laid so as to engage with each other, the exterior materials have a substantially rhombic shape in which two pairs of opposing internal angles have the same internal angle, and a short diagonal line connecting the two obtuse angles is a support member. The long diagonal line connecting the two acute angles has a length straddling the distance between two adjacent support members, and the water upper top and the water lower top of the exterior material are on the same support member. We propose an exterior structure characterized in that the corner portions on both sides are fixed on the support members adjacent to the left and right of the support member, respectively .

The present invention also proposes an exterior structure characterized in that, in the exterior structure, a holding member is fixed to the support member, and the water upper top portion of the exterior material is fixed by the holding member.

The exterior structure of the present invention is a "horizontal" type (horizontally long rhombus) exterior material in which an obtuse angle is located on the upper top of the water on a base in which a plurality of support members are arranged at equal intervals along the flow direction. For the base material in which multiple support members are arranged at equal intervals so as to be orthogonal to the flow direction, a "vertical" type (vertical rhombus) exterior material with an acute angle located at the top of the water is used. , Since the short diagonal connecting the two obtuse angles is arranged substantially parallel to the support member, the two obtuse angles forming both ends of the short diagonal are on the same support member, and the two acute angles forming both ends of the long diagonal are It can be securely fixed on the support members adjacent to the support members . Therefore, it is possible to easily and highly accurately construct a rhombus exterior structure or the like having excellent designability and structural advantages. Moreover, since the long diagonal line connecting the two acute angles is twice as long as the arrangement interval of the two adjacent support members, it is formed in a vertically long or horizontally long substantially rhombic shape.

Further, since the exterior structure of the present invention uses the exterior material having the above structure , both ends of the short diagonal line are on the same support member and both ends of the long diagonal line are the support members of the support members arranged at equal intervals on the base. A rhombus exterior structure, etc., which can be securely fixed on the support members adjacent to the left and right sides of the above, has excellent design, and has structural advantages, etc., was easily and with high accuracy. It becomes a thing.

Further, a holding member is fixed to the support member, and when the water upper top portion of the exterior material is fixed by the holding member, the exterior material itself can be fixed without forming a hole such as a fixing tool. There is no risk of water leakage, and the exterior material can be evenly engaged around the upper water top, and stable fixing strength can be obtained. Further, in this case, since the support member can be constructed as a "core", the construction accuracy is high. In particular, when the holding member is fixed by the locking claw of the support member, it can be easily fixed at a predetermined position, and the workability and construction accuracy are high.

The water upper top portion 115c can be reliably fixed on the support member 2C with respect to the support members 2C arranged at equal intervals (EI') on the base (heat insulating material) 4C. That is, the attachment point of the exterior material 1C to the support member 2C is one place of the water upper top portion 115c, but since the adjacent exterior materials 1C and 1C are engaged with each other, they can be securely fixed. Therefore, it is possible to easily and highly accurately construct a rhombus exterior structure or the like having excellent designability and structural advantages.
Further, the position is adjusted while visually observing the positioning portion 14c provided near the water upper top portion 115c of the exterior material 1C from the opening 53c provided close to the locking portion 52c of the holding member 5C, and the exterior material 1C is positioned appropriately. Can be attached to.

Further, in the exterior material 1D in the fourth embodiment, the positioning portion 14d is provided in a concave shape on the underwater side in which the sharp water upper top portion 115d is folded back to the underwater side.
The positioning portion 14d refers to a driving position of a fixing tool 6 such as a screw.
Further, also in the exterior structure of the fourth embodiment in which the exterior material 1D, which is the vertical rhombic exterior material, is fixed to the support member 2D by the fixing tool 6, the exterior material 1D is also the same as in the first to third embodiments. Can reliably fix the water upper top portion 115d on the support member 2D with respect to the support members 2D arranged at equal intervals (EI'). That is, the fixing point of the exterior material 1D to the support member 2D is one place (fixing tool 6) on the water upper top 115d, but since the adjacent exterior materials 1D and 1D are engaged with each other, they must be securely fixed. Can be done. Therefore, it is possible to easily and highly accurately construct a rhombus exterior structure or the like having excellent designability and structural advantages.
