Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone panel used as an outer wall of a building or an outer wall of a curtain wall, as well as an inner wall.

[0002]

2. Description of the Related Art When a stone panel using a plate-shaped stone material is used as an outer wall material of a building, the movement of the stone material is restrained by a support metal object which is one element of the panel to prevent the stone material from falling off. It is necessary to be supported in a fixed state, but the conventional support metal fitting meshes with the grooves formed continuously on the upper and lower end faces of the stone, and sandwiches the stone from the top and bottom by connecting to the frame that is directly connected to the structure Because of the structure, the existence of a frame is indispensable for restraining the stone material, and its production is done by connecting the support metal pieces to the frame in the state that the supporting metal pieces are engaged with the top and bottom of the stone material, so the assembly work is done. It is getting complicated.

Further, in order to form a groove on the end face of a stone material, it is necessary to secure a certain thickness or more in the stone material in order to prevent cracks on both sides of the groove, and therefore there is a limit to thinning. Therefore, the conventional stone panel is generally heavy, which leads to a decrease in workability of installation on site, and the use of the stone panel is limited to the outer wall because of its large wall thickness.

The present invention has been made in view of the actual situation of conventional stone panels, and is intended to newly propose a stone panel having a simple structure and a wide range of applications.

[0005]

In the present invention, the structure of the stone panel as a unit is simplified by supporting the stone material while restraining the stone material from the back side by at least a pair of supporting metal pieces, and at the same time, the manufacturability is improved and the thickness is reduced. Enable
Aim to expand applications.

A pair of insertion grooves inclined with respect to the surface of the stone are formed from the mounting position of each support metal on the back side of the stone, and the stone is sandwiched by the pair of support metal in the insertion groove.

[0007] The supporting metal is a contact piece that abuts against the back surface of the stone material, a connecting piece that projects from the contact piece to the opposite side of the stone material perpendicularly thereto, and a contact piece inclined from the surface of the stone material from the contact piece. Has a support piece that projects toward the side and is inserted into the stone from the back side, and the two pieces form a pair, and the support pieces are inserted into the stone facing the opposite sides, and the connecting pieces are abutted and connected to each other. As a result, the stone material is sandwiched and integrated with the stone material while restraining the movement in the in-plane direction and the out-of-plane direction.

[0008] The stone material can be restrained and supported by a pair of supporting metal pieces, and the absence of the frame simplifies the structure of the stone panel, and the production is performed only by inserting the supporting metal pieces into the stone material and connecting them. , The manufacturability is enhanced.

Further, since the insertion groove into which the supporting metal is inserted is formed from the back side of the stone material, there is no thin portion around the insertion groove, so that the stone material itself can be made thin and the weight of the stone panel can be reduced. Installation workability on site is improved.

Since the stone panel can be connected to the structure directly in the support metal or through the frame connected to the support metal, the shape and type of the target structure can be selected and the thickness can be reduced. Since it is possible to reduce the weight, it can be used not only as an outer wall material but also as an inner wall material, a floor material, or a finishing material for an interior, and the range of its applications is expanded.

[0023]

The present invention is as described above, and two stones are paired and connected to each other to sandwich a stone material and to integrate the stone material while restraining its in-plane and out-of-plane movements. Since the stone material is supported by at least a pair of support hardware, the structure of the stone panel as a unit is simplified, and its manufacturability can be improved.

Further, since the insertion groove into which the support metal is inserted is formed from the back side of the stone material, there is no thin portion around the insertion groove, so that the stone material itself can be made thinner and the weight of the stone panel can be reduced. Installation workability on site is improved.

In addition, since the stone panel can be connected to the structure directly in the supporting metal or through the frame, the structure and the type of the structure to be installed are not selected, and the thickness and weight can be reduced. Therefore, the stone panel can be used not only as an outer wall material but also as an inner wall material, a floor material, or a finishing material for the interior, and the range of its applications can be expanded.
