Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method of building panels such as wall boards and ceiling boards of buildings.

[0002]

2. Description of the Related Art Building panels called siding materials are often used on the outer wall surface of buildings. The siding material is a panel in which a metal material and a synthetic resin layer are integrated, and generally, a long product having a width of 30 to 45 cm is cut into a required size and used. The metal material is processed into a groove type having mounting edges that project in the horizontal direction on both sides, the synthetic resin layer is a foam layer, and the foam layer is formed by foaming the foamable urethane stock solution discharged into the groove of the metal material. The surface material is adhered to the surface, and the mounting edge of the metal material is fixed on the base material.

[0003]

However, the panel in which the metal material and the synthetic resin layer are integrated has a problem that warpage occurs. Especially, the warp of the panel is greatly affected by the shrinkage rate of the face material of the synthetic resin layer. Therefore, a warp that causes the surface of the metal material to be a curved concave surface is generated. The warp of the panel is caused not only by the problem at the time of its manufacture but also by the environmental conditions of the construction site, and particularly when it is installed under the environment where it is directly exposed to the sunlight, the warp is remarkable.

Conventionally, the panel 21 is often constructed by nailing both mounting edges 24 between the pillars 22 and the studs 23 of the building as shown in FIG. 7, but in this case, the surface of the metal material is made into a curved convex surface. When warpage occurs, each of the panels 21, 21, ... Adjacent to each other is deformed into a middle protrusion and is unsightly. As described above, there are problems that the direction and degree of the warp of the panel are not stable, and the finish of the construction surface is greatly affected.

In order to solve this problem, conventionally, the strength of the panel itself has been increased. In order to increase the strength of the panel, a method of incorporating a reinforcing material in the panel or a method of adding rib-like unevenness to the metal material to increase the strength can be considered.

However, even if the reinforcing material is filled in the panel material,
Alternatively, even if the metal material is subjected to a reinforcement treatment, the warp of the panel is not basically eliminated only by increasing the strength against deformation, but this is merely suppressed by a force exceeding the warp. However, the high degree of reinforcement of the panel is against the original use of the siding material. Siding materials are often used for outer walls of warehouses because of their light weight and simple structure.

It is an object of the present invention to provide a method of using a panel which is preliminarily warped in a certain direction and applying it flatly.

[0008]

To achieve the above object, according to an aspect of, in the method of constructing the panel according to the present invention, there is provided a method of constructing the panel pasting the panel on the base material, panel

A concave surface is formed on the surface of the metal material.
On the surface where the layer is exposed, a convex curved surface is formed.
With the curved concave surface of the material as the outer surface, the curved convex surface is supported on the flat surface of the base material, both edges of the metal material formed on the extension of the curved convex surface are fixed to the base material, and the curved concave surface of the metal material is the flat surface of the base material. It is to be flattened according to.

Further, at least a part of the curved convex surface of the synthetic resin layer is supported on a base and formed on an extension of the curved convex surface.
By fixing both side edges of the metal material to the base material, it is possible to prevent warpage of the panel after the construction.

Further, the base material is a furring strip mounted in parallel across at least two columns, and the furring strips of each row have the same plane surface and two curved convex surfaces of the synthetic resin layer. The curved concave surface of the metal material is corrected to a flat surface by supporting the above-mentioned furring edge and following the flat surface formed by two or more furring edges.

Further, gold Shokuzai are those having a groove which one surface is opened by bending processing of the metal material, and a mounting edge, which is horizontally bent outward from both side rising part of the groove, the synthetic resin The layer is a foam layer in which face materials are adhered to both front and back surfaces, and is inserted and installed in the groove of the metal material, causing warpage due to the difference in the properties of the both material, and the surface of the metal material is shaped into a curved concave The exposed surface of the synthetic resin layer is shaped into a curved convex surface, and the exposed surface of the synthetic resin layer is supported on a base material to correct the curved concave surface of the metal material into a flat surface.

[0012]

The function of the synthetic resin layer is preliminarily shaped so that it warps in a certain direction. The warp of the synthetic resin layer is most affected by the difference in shrinkage ratio between the double-sided materials. Therefore, the heat shrinkage rate of the face materials to be attached to both sides of the synthetic resin layer is made different, or tension is applied to one of the face materials at the time of attachment to cause warpage in the synthetic resin layer in advance, and the side that becomes the curved concave surface is metal. If bonded in the groove of the material, the metal material will be deformed following the warp shape of the synthetic resin, and the panel will have a curved shape with the surface of the metal material as the curved concave surface and the exposed surface of the synthetic resin layer as the curved convex surface. Be imprinted.

When installing the panel, if at least a part of the curved convex surface of the panel is supported on the flat surface of the base material and the mounting edges at both ends are pressed against the base material to be fixed along the flat surface of the base material, the panel warps. Is corrected, and a flat surface is constructed on the groundwork.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, the present invention applies a siding material to the surface of a base material as an exterior material of a building. The siding material referred to in the present invention is the panel 4 in which the metal material 1 and the synthetic resin layer 2 are combined and integrated. Metal material 1
As shown in FIG. 2, the metal plate is bent to form the rising portions 5 on both sides, and the groove 6 is formed between them.
Further, it is further bent horizontally outward to provide a pair of mounting edges 7, 7.

The synthetic resin layer 2 is provided in the groove 6 of the metal material 1. As shown in FIG. 3, the synthetic resin layer 2 is formed by adhering face materials 8 and 9 to both front and back surfaces of a urethane foam layer 3 which is raised to a constant thickness. In the embodiment, the surface material 8 and the back surface material 9 are made of materials having different heat shrinkage rates. The backside material 9 is made of a material having a thermal shrinkage rate that is relatively smaller than that of the surface material 8 and is thermally stable.
Use a material with a large heat shrinkage. In the present invention, the size of the thermal shrinkage is relative, and the condition that the front surface material 8 contracts more than the back surface material 9 under the temperature of the outside air is satisfied. Therefore, selection of the material of the face material is not necessarily the same depending on the case where the panel is constructed in a cold region, the extreme heat region, or the wetland.

In any case, the degree of shrinkage of the front surface material 8 depends on the back surface material 9
If it is relatively larger, the foamed layer 3 is deformed in accordance with the difference in shrinkage ratio between the double-sided materials 8 and 9, and the surface material side has a curved concave surface,
It is shaped in a curved shape with the back material side as a curved convex surface.

On the other hand, an adhesive is applied to the groove 6 of the metal material 1, and the surface material 8 side of the obtained synthetic resin layer 2 is inserted into the groove 6 and fixed integrally. The thickness of the synthetic resin layer 2 is set to be the same as the rising height of the rising portion 5 of the groove 6, and the surface of the back surface material 9 of the synthetic resin layer 2 is formed flush with the mounting edge 7.

When the synthetic resin layer 2 is fixed to the metal material 1,
The metal material 1 is deformed according to the shape of the warp of the synthetic resin layer 2, and the surface of the metal material 1 is curved as shown in FIG.
0, a warp that forms the curved convex surface 11 of the back surface material 9 is formed.

The panel 4 is cut into a required length and used, for example, as an exterior material for a building. In the present invention, the panel 4 which has been previously warped in a certain direction is not straightened at the time of construction. It is used as it is.

FIG. 5 shows an example in which a furring strip 13 installed in parallel in the lateral direction across two or more columns 12 of a building serves as a base material, and the panel 4 is mounted on the row of furring strips 13. ing. The furring edges 13 of each row are such that the respective surfaces form the same plane as a whole.

When the panel 4 is attached, in FIG. 6, the metal material 1 serving as the curved concave surface 10 faces the outer surface, and the convex surface 11 of the back surface material 2 is supported on the furring strip 13 so that both mounting edges 7 are attached. When the panel 4 is supported by the furring strip 15, the concave surface 1 of the metal material 1 is forcibly flattened following the flat surface of the furring strip 13 while being pressed against the furring strip 13 and being nailed to the furring strip 13 as it is. To be done.

In FIG. 5, two or more pillars 1
The furring strips 13, 13, ...
2 on the furring strip 13 as long as the surface of the
The surfaces of the panels 4, 4, ..., Which are mounted in parallel in a row or more, are flush with each other, and the surface of each panel 4 is not uneven unless the nail fixing the panel 4 is loosened.

In the above embodiment, since the panel 4 is supported by the furring strip 13 over the entire range of the warping direction, the warping of the panel 4 is automatically corrected to a flat surface following the flat surface of the furring strip 13. However, in order to correct the warp of the panel 1 and apply it in a planar shape, it is not always necessary to support the entire area of the back surface material 2, but at least the most protruding portion of the curved convex surface 11 will support the panel 4 as a whole. Can be constructed in a flat shape.

Therefore, in FIG.
When the panel 4 is laterally stretched in parallel with the rows of 3, 13, ... Must be arranged in the position corresponding to. Further, as the base material, the example in which the furring strip mounted between the pillars is used has been described in the embodiment, but the base material is not limited to the furring strip.

After the construction, even if the panel is exposed to direct sunlight and is deformed in a direction to further expand the warp, the convex surface is supported by the base material, so that the force in the direction in which the panel is deformed is Since it acts as a force in the direction of pressing the base material against the base material, the attachment edge is not overpowered and does not float up from the base material.

[0026]

As described above, according to the present invention, since the panel is preliminarily warped in one direction and the warped panel is rectified when the construction is performed, the construction surface is kept flat. Also, even if a force to expand the warp is applied to the panel after construction, this is converted into a force in the direction of pressing on the mounting edge of the panel and the base material, so that the panel construction surface does not deform, In addition, neither lifting nor peeling from the base material occurs.

According to the present invention, even if the siding material is used without any special reinforcement treatment on the panel, the structure can be simple and the weight can be maintained while maintaining the flat surface. It has the effect that it can be widely used for construction.
