Description

  The present invention is a support member in which a short diagonal line connecting two obtuse angles is a substantially rhombic shape arranged substantially parallel to the support member and arranged at equal intervals on the base, with the water-side top portion on the support member. The present invention relates to an exterior material that can be reliably fixed.

  In general, flat roofing is a method of stacking a relatively small amount of exterior material and stacking it. It can be constructed with ordinary sheet metal tools and is widely applied to a wide variety of roofs. Widely applied mainly to roofs. Hishibuki belonging to this flat roof, in addition to the design that the exterior material exhibits a rhombus, most of the dew condensation generated on the back side can be discharged to the front side of the roof material on the underwater side, and flow down, It also has a structural advantage that the effect of moisture on the base material is small.

As a structure related to such a rhombus roof, for example, the structures described in Patent Documents 1 and 2 have been known.
Patent Document 1 describes a structure in which the hypotenuse (engagement receiving portions 12 and 12A) on the water side of one exterior material (metal face material 11) is fixed by a plurality of suspenders (18) ( (Fig. 7). Although not shown, the suspension (18) is fixed to the base plate. The top of the water-side tip of the exterior material is folded. In addition, when laying such a sheet-like exterior material, a method is used in which marking is performed on the base material and sequentially fixed so that the top of the surface material is located with respect to the marking line. There is.
Patent Document 2 describes a structure in which the top of the water-side tip of an exterior material (flat roof construction board A) is fixed by a suspender (D) (FIG. 18). Then, as shown in FIGS. 19 and 20, the suspension (D) is fixed to the base plate through (penetrating) the base material (C).

Japanese Utility Model Publication 7-11219 (FIG. 7) JP-A-2-128049 (FIGS. 18 to 20)

However, in the structure of Patent Document 1, the hypotenuse on the upper side of the water is fixed by the two suspensions, but the fixing points are not uniformized, and there is a possibility that the negative pressure strength of the exterior material may vary. . Therefore, marking is performed on the base, and it is fixed sequentially so that the top of the roof material is positioned with respect to the "line", so when fixing the engagement receiving part with multiple suspenders It is necessary to fix the hanger while locking it in the direction intersecting with the wire, and the work of fixing the hanger while holding it so as not to cause misalignment requires a great deal of work. Further, in addition to the positioning as the exterior material, it is necessary to position the hanger, which is a very troublesome work.
It should be noted that the fixing of the sling requires two types of positioning, that is, the position with respect to the hypotenuse (where the tip of the hanger is hooked on the hypotenuse) and the position with which it is fixed on the field material (where the screw is hit). If it is pulled too much, the hypotenuse will be deformed and the exterior material will be displaced, and if it is loose, the strength will be insufficient.

  Further, in the structure of Patent Document 2, although the position for fixing the hanger is specified with respect to Patent Document 1, the fastening (depth) of the screw or the like at the fixing position is not stable. Moreover, since it is fixed to a field material (control panel: plywood), the pulling strength of the screw is insufficient. Further, when the base material is a heat insulating material made of synthetic resin, there is a risk that the fire may spread and fall during a fire.

  Therefore, in the present invention, a short diagonal line connecting two obtuse angles is a substantially rhombic shape in which the short diagonal line is arranged substantially parallel to the support member, and the water-side top portion is supported by the support member with respect to the support member arranged at equal intervals on the base. It is an object of the present invention to propose an exterior material that can be securely fixed above.

  The present invention has been proposed in view of the above, and is formed by bending the peripheral edge of the face plate portion to the front surface side or the back surface side to form the engaging portion and the engaged portion, respectively, and to form a plurality of supporting members. In an exterior material that is laid on a substrate arranged at equal intervals along the flow direction, the face plate portion is a horizontally long rhombus in which two sets of facing inner angles are equal, and a short line connecting two obtuse angles. The diagonal line is arranged substantially parallel to the support member, the long diagonal line connecting the two acute angles has a length that spans at least two adjacent support member intervals, and the water-side top portion of the exterior material is on the support member. The water-side top portion and the underwater-side top portion can be mounted on the same support member, and the corner portions on both sides can be arranged on the support members adjacent to the left and right of the support member, respectively. The two sides that form the Proposes a sheathing material which is characterized in that the engaging portion by bending the two sides forming an obtuse angle on the back side located on the water bottom side apex to. The oblong rhomboidal exterior material having an obtuse angle at the apex on the water side is referred to as a “horizontal placement” type exterior material in the following description.

  Further, according to the present invention, the periphery of the face plate portion is bent to the front surface side or the back surface side to form the engaging portion and the engaged portion, respectively, and the plurality of supporting members are equally spaced so as to be orthogonal to the flow direction. In the exterior material to be laid on the base material, the face plate portion has a vertically elongated rhombus shape in which two pairs of facing inner angles are equal to each other, and a short diagonal line connecting two obtuse angles is substantially parallel to the support member. Is disposed on the above, the long diagonal connecting the two acute angles has a length that spans at least two adjacent support member intervals, the water-side top portion of the exterior material is attachable on the support member, and The corners can be arranged on the same support member, and the water-side top and the water-side top can be respectively arranged on the support members adjacent to the left and right of the support member, and two sides forming an acute angle located on the water-side top are on the surface side. It is bent to form an engaged part, and it is located at the opposite water-side top. It is to propose also a sheathing material which is characterized in that the engaging portion by bending the two sides form an acute angle on the back side. In the following description, a vertically long rhombus-shaped exterior material having an acute angle on the water-side top is referred to as a "vertical installation" type exterior material.

In addition, "a short diagonal line connecting two obtuse angles" is nothing but a short diagonal line formed with two obtuse angles as an edge, and "a long diagonal line connecting two acute angles" has two acute angles as an edge. It is a long-diagonal line formed, and is formed in a diamond shape, but does not include a substantially square shape such as the exterior material in Patent Documents 1 and 2.
In addition, "the length across the space between two adjacent support members" means that the length is twice the space between the support members, which is "equal space".
Furthermore, “rhombic shape” means that the rough planar shape of the face plate portion is a rhombic shape, but for example, if a sharp side is cut or folded to include a minute side, it is strictly a six-sided shape. It is meant to include shapes such as polygons and octagons.

  The exterior material of the present invention is a substantially rhombic shape in which a short diagonal line connecting two obtuse angles is arranged substantially parallel to the support member, and a plurality of support members are arranged at equal intervals along the flow direction. The base material is a "horizontally placed" type (horizontally long rhombus) exterior material in which the obtuse angle is located at the top of the water, and a plurality of support members are arranged at equal intervals so as to be orthogonal to the flow direction , Using a "vertical" type (long rhomboid shape) exterior material in which an acute angle is located on the water-side top, the corners on both sides are on the same support member, and the water-side top and the water-side top are the support members. Can be reliably fixed on the support members adjacent to each other on the left and right sides of the. Therefore, it is possible to easily and highly accurately construct a rhombus exterior structure having excellent design properties and structural advantages. Moreover, since the long diagonal connecting the two acute angles is twice as long as the interval between the two adjacent support members, it is formed into a vertically or horizontally long diamond shape.

The structure is laid so as to fit together, and the water-side top portion of the exterior material (A) is fixed on the support member (B).
In the following, the support member (B), the base (C), and the exterior material (A) will be described in detail in this order.

A plurality of support members (B) used for the exterior structure are arranged at equal intervals (= arrangement interval EI) on the base (C) as described above, and are arranged in the flow direction. It may be one that intersects with the flow direction (substantially right angle shape), and the arrangement direction thereof can be set arbitrarily.
The arrangement direction of the support member (B) is not particularly limited, but it may be selected in the form of the exterior material (A), and the apex above the water is obtuse as in the illustrated embodiment described later. In (A) horizontal type diamond-shaped exterior material, it is preferable to dispose the support member in a direction along the flow direction, and in (A) vertical-placed type diamond-shaped exterior material, the water-side apex has an acute angle.
