Abstract

(57) [Summary] (Corrected) [Purpose] To increase the flexural strength of the siding material in the longitudinal direction. [Structure] Bend both sides in the width direction of the coated metal strip to the back side to form a groove shape in cross section, and fill the inside of the groove shape with a lining material,
Further, in the siding material in which the backing material is arranged on the surface of the backing material, the backing material is a metal strip which is embossed with a pattern in which the uneven pattern shape extends in the length direction.

Description

[Detailed description of the device]

[001]

[Industrial application]

 The present invention relates to a siding material having increased flexural strength in the length direction.

[002]

[Prior art]

 For the siding material to be applied to the wall of a house, etc., bend both sides in the width direction of the painted metal strip to the back side to form a groove shape in cross section, and fill the inside of the groove shape with a lining material so that it will not easily get depressed by an impact. In addition, the backing material is placed on the surface of the backing material to improve the appearance of the back side and protect the backing material.

FIG. 3 shows an example of this siding material 1, in which both sides in the width direction of the coated metal strip 2 are bent to the back side to form a groove in cross section, and a convex portion protruding in the width direction to a bent portion on one side. After forming a concave portion 4 into which the convex portion 3 can be inserted at the bent portion of the opposite side of the portion 3, the groove-like back side is filled with a backing material 5 such as foamed resin or an inorganic board, and the backing material 5 is formed. A flat backing material 6 such as an aluminum foil composite material or a metal plate is fixed to the surface so that both sides are located in the groove. As the coated metal strip 2 of the siding material 1, not only a smooth one but also an embossed one is used.

As shown in FIG. 4, the siding material 1 is constructed by arranging the base material 7 at a predetermined interval and driving the siding material onto the base material 7 with nails. In No. 7, it was necessary to narrow the gap to some extent so that the siding material 1 would not be bent even if pushed.

[0095]

[Problems to be solved by the device]

 However, if the interval between the base materials 7 is narrowed, there is a problem that the number of base materials 7 and the time and effort required for mounting the base materials 7 increase, and the construction cost increases. Therefore, the present invention provides a siding material that solves these problems.

[0096]

[Means for solving problems]

 In the present invention, the backing material is a metal strip that is embossed with a pattern in which an uneven pattern shape extends in the length direction.

[0097]

[Action]

 When an embossed metal strip is used as the backing material, the rigidity of the metal strip increases even with the same plate thickness, so the flexural strength of the siding material in the longitudinal direction increases. Further, when the embossed pattern of the uneven pattern extends in the lengthwise direction of the siding material, the flexural strength in the lengthwise direction is further increased. Therefore, it is possible to widen the gap between the base materials on which the siding material is applied.

The backing metal strip is preferably a plated steel strip or a coated steel strip in terms of strength, corrosion resistance, price, etc., but other metal strips may be used. Further, the embossed concavo-convex pattern shape applied to the metal strip may be of any length and any length as long as the length in the length direction of the metal strip is longer than that in the width direction.

[0109]

【Example】

 1 and 2 show an embodiment of a siding material 1 according to the present invention. The shape, structure and reference numerals are the same as those in FIG. 3, and the coated metal strip 2 is coated molten zinc. A galvanized steel strip is used, a foaming resin is used as the backing material 5, and an embossed coated hot dip galvanized steel strip is used as the backing material 6. The backing material 6 is embossed on the entire surface of the elongated diamond-shaped concavo-convex pattern 8 extending in the lengthwise direction of the coated metal strip 2 and is in close contact with the backing material 5.

The strengths of the siding material 1 having such a structure and the conventional siding material 1 were compared as follows. (1) Test method According to "bending test method for building boards" specified in JIS A 1408. (2) Specimen

(3) Specimen size The working width was 404 mm, the fitting height was 16 mm, and the length was the distance between fulcrums +200 mm. (4) Pressing method Pressing was applied from the coated metal strip 2 side using a 30-ton universal testing machine. (5) Bending strength The bending proportional limit load was measured, and the measured values of three times were averaged. (6) Result

[0112]

[Effect of the device]

 As described above, in the siding material of the present invention, the flexural strength in the length direction is reinforced by the backing material, so the spacing of the base material to be hit can be made wider than before, and the base material and the hitting work can be reduced. You can In addition, since the design of the back surface of the siding material is improved, in a building such as a warehouse where the interior finish is not important, it is sufficient to apply the siding material and the interior can be omitted. In addition, if the backing material is embossed, when the backing material is filled with resin by foaming during siding material manufacturing, the anchoring effect of the embossed pattern increases the adhesion between the backing material and the backing material. Become.
