2. Description of the Related Art Conventionally, hollow cement-based panels used for surface structures such as outer walls and roofs of buildings are relatively lightweight and have excellent fireproofing and sound insulation properties, so that the exterior of the building Widely used as a material.

In order to adjust the appearance of the panel, the panel surface is painted or the surface material such as tile is adhered. Therefore, there is a problem that the durability of the cement-based panel is adversely affected. Also, regarding the design of the appearance, it is natural that a three-dimensional surface structure is not obtained by painting, and for example, for a surface structure of a three-dimensional continuous long shape, not only by painting but also by tiles. It was a place where even things could not be expected, and its exterior design was limited to the painted surface and tile surface.

Further, since it is unavoidable that a gap is structurally generated at the connection portion between adjacent panels, the gap is appropriately closed by joint treatment, but the treatment method is waterproofing by packing or sealing. Since only the treatment is required, the workability is extremely poor, and the joint waterproofness is impaired or deteriorated due to vibration such as an earthquake or secular change.

In order to solve these problems, the applicant has proposed a surface structure in which the surface of a hollow cement-based panel is coated with a metal plate having excellent weather resistance (see Japanese Patent Application No. 4-44589). .

[0006] Then, by further improving the structure, in order to mount the metal plate, the structure is structured so that a weak portion of strength and heat insulation is not formed in the thickness direction of the panel, and the metal plate is mounted to the panel. It succeeded in simplifying the structure and completed the present invention.

[0007]

The problem to be solved is that it is not possible to obtain a unique appearance design by a decorative metal plate other than painting and tiled without impairing the advantages of the hollow cement panel. In addition, it is not possible to prevent such a metallic decorative surface structure from deteriorating the panel strength and heat insulating property and complicating the attachment structure of the metal plate.

In a surface structure of a building consisting of a metal plate whose surface is decorated according to the allocation width of the stepped portion, the panel is located on the elevation base side of the stepped portion from the opening height with the panel surface as a reference surface. And a fitting groove having a high internal height is formed, the metal plate has an engaging portion at a lower end, and an upper end is elastically fitted to the fitting groove and is engageable with the engaging portion. It is characterized in that the engaged portion is formed.

Further, the present invention is characterized in that the intervals of the step portions closest to the upper and lower end portions of the adjacent panels are formed to have a size equal to the effective width of the metal plate.

Further, according to the present invention, the upper and lower end portions of the adjacent panels, in the combined state of the upper and lower end portions,
It is characterized in that it is formed in a manner to be the one step.

Further, according to the present invention, a panel fixing tool is provided which extends from the rear surface of the panel along the space between the upper and lower panels and has a locking portion which is locked to the engaged portion of the metal plate in the fitting groove. The feature is that the upper end can be fixed to the base.

In the construction of the present invention, in principle, a hollow cement-based panel is laid over the entire surface of the target surface, and then a metal plate is elastically fitted in the fitting groove of the panel for installation. However, if a heavy load is applied to the surface of a metal plate such as a roof surface of a snowy area in a plane structure, the panel fixing tool should be attached to each panel and the reinforcing means should be incorporated. Is also possible.

[0013]

Therefore, due to the existence of the fitting groove, a dangerous fragile portion in the panel thickness direction cannot be formed, and the original strength of the panel can be obtained without any weak point in strength.

Since a dangerous fragile portion in the thickness direction of the panel, that is, a thin portion as a thermal weak point that lowers the heat insulating property cannot be formed, the heat insulating property inherent to the hollow cement-based panel can be obtained.

The end structure of the metal plate that fits in the fitting groove of the panel is simplified, and the molding process and material cost can be reduced to the same level as or lower than that of a general exterior metal plate.

Since the engaged portion at the upper end of the lower metal plate is elastically fitted into the fitting groove of this panel, and the engaging portion at the lower end of the upper metal plate is engaged with this engaged portion. A good fitting / engaging relationship can be obtained even if the fitting accuracy with the fitting groove is relatively rough.

Since the metal plate attached to the surface of the hollow cement-based panel is applied to the surface of the panel, the durability of the panel is not affected by the makeup, and the design is not expected by painting or tiles. An excellent makeup surface can be obtained.

Further, according to the present invention, since the interval between the step portions closest to the upper and lower end portions of the adjacent panels is formed to have the same dimension as the effective width of the metal plate, the connection portion between the panels is The front side is covered with a metal plate,
It is possible to prevent rainwater from entering the connection portion side.

Further, according to the present invention, the upper and lower ends of the adjacent panels are
