2. Description of the Related Art Generally, in the above-mentioned mounting structure for a column exterior decorative plate material, various designs such as round columns and prisms are provided around an H-shaped steel or square steel which is a base skeleton. The various parts of the decorative sheet material are assembled and fixed. As these exterior decorative board materials,
Metal plate material such as aluminum that is difficult to work on site but is relatively lightweight, ceramic plate material such as calcium silicate plate that is expensive but has a high-quality feel, or ceramic plate material that is obtained by low-foam extrusion molding. There is known a synthetic resin plate material that has a similar texture, is lightweight, has excellent workability on site, and can be provided at low cost.

However, when metal plate materials are used, they are assembled by on-site construction using fixtures, but there is a problem that the fitting of the members divided into the respective parts cannot be properly accommodated. Also, when using ceramic plate materials, the weight of the material itself is quite large, and in order to reliably support this weight, screws are fixed at a fairly fine pitch, impairing the design feeling of high quality texture. There was something that happened. Furthermore, in the conventional synthetic resin plate material, whether it is a round pillar or a square pillar, it is configured by combining four parts that divide the circumference of the pillar into four parts, but at each joint it is fixed with screws or nails. However, the workability in assembling as well as the design is not so good, and the advantage of being made of synthetic resin has not been fully utilized.

The present invention has been devised in order to effectively solve the above-mentioned conventional technical problems relating to the mounting structure of the exterior decorative sheet material for columns as described above. Therefore, an object of the present invention is to provide a mounting structure for a column exterior plate material that can enhance its designability and assembly workability in order to maximize the advantages of the synthetic resin plate material obtained by low foaming extrusion molding. is there.

The mounting structure for a column exterior plate material according to the present invention has the following constitution in order to solve the problems of the prior art as described above and to achieve the object. That is, in the mounting structure of the exterior plate material for a column that attaches and fixes the exterior plate material made of a synthetic resin obtained by low foaming extrusion molding around the base structure, the base structure is a prismatic member having a substantially square cross-sectional shape, and Mounting base materials each having the same cross-sectional shape are mounted and fixed on three of the four peripheral surfaces of the base frame, and the exterior plate material is 2 in the circumferential direction.
Each of the divided pieces of the exterior plate material has an assembling portion in which both ends fit with the mating divided pieces, and the assembling portion elastically deforms the divided pieces when the divided pieces are assembled with each other. In this state, each of the divided pieces has a convex portion and a concave portion which are paired with each other so as to allow the divided piece to be restored to its original shape, and the exterior plate member has an inner peripheral portion on the three surfaces of the base skeleton. Has a seating surface which is seated via an adhesive on the end surface of the mounting base material fixed to the.

[0006]

In the structure for mounting a pillar exterior plate material according to the present invention, the two-part exterior plate material obtained by low foaming extrusion molding and fixedly mounted around the base frame is at both ends of each divided piece. It is integrated by combining the assembly parts formed in the parts. At the time of this combination work, the concave portion and the convex portion formed in both the assembly portions are pushed in and meshed with each other while the elastic deformation of the divided pieces themselves accompanies, and in the meshed state, the elastic deformation returns to the original and both It doesn't come off. The exterior plate material is formed by dividing the tubular shape into two in the circumferential direction, that is, vertically divided, and these are light, so that the operator can attach the exterior plate material by simply pressing the two divided pieces in both hands and pressing them.

Regarding the positioning of the exterior plate material with respect to the base frame body, the attachment base material is attached and fixed to the three surfaces of the base frame body whose cross-sectional shape is approximately square, whereby three surfaces orthogonal to each other are defined, and the exterior plate material The seating surface formed on the inner peripheral side is seated on these three surfaces to define the position in the vertical and horizontal directions. However, in any one of the vertical and horizontal directions, the seating surface abuts against the end surface of the base material to prevent further movement in that direction, but it is possible to move in the opposite direction. By giving this degree of freedom of movement, there is a margin in the handling of both divided pieces in the assembling work of the exterior plate material, and the assembling can be done easily.

Further, the exterior plate material is fixed by interposing an adhesive between the seat surface of the exterior plate material and the end surface of the mounting base material. Therefore, since no nails or screws are used, a high-quality texture can be obtained without impairing the aesthetic appearance of the design.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A mounting structure for a column exterior plate material according to an embodiment of the present invention will be described below with reference to FIGS. As shown in the cross-sectional view of FIG. 1, a square pipe 1 is provided at the center of a pillar as a base frame, and a circular exterior plate member 2 is attached to surround the periphery of the pipe. Square pipe 1
Between the outer plate member 2 and the outer plate member 2, there is provided a mounting base member 3 made of wood or synthetic resin having the same size. The base members 3 are attached to the three faces of the square pipe 1 with screws 4. There is.

The exterior plate member 2 is divided into two parts, each of which has the same shape, and in the assembled state shown in FIG. 1, its cross-sectional shape is symmetrical with respect to the axis of the column. At the assembly part, as shown in FIG.
A concave portion 5 is formed at one end of a and 2b, and a convex portion 6 that fits into the concave portion 5 of the mating plate is formed at the other end. Rib grooves 7 having a substantially trapezoidal cross section are formed on the outer peripheral surfaces of the plate members 2a and 2b.
There are multiple decoratively placed along the axial direction. In the present embodiment, the rib grooves 7 are arranged at positions with a central angle of 45 degrees, and the rib grooves 7 are also formed in the assembly portion of the concave portions 5 and the convex portions 6 by both.

On the inner peripheral side of the tip of the convex portion 6, there is formed a convex step portion 9 projecting toward the inner peripheral side by about 0.5 mm. On the other hand, a concave step portion 10 for receiving the convex step portion 9 is formed at a position in the concave portion 5 corresponding to the convex step portion 9.
When the one convex portion 6 is inserted into the mating concave portion 5, the two plate members 2a, 2b are assembled while elastically bending by the protrusion of the both convex stepped portions 9, 9 and, in the assembled state, the convex stepped portion is formed. The portion 9 and the concave step portion 10 mesh with each other and cannot be separated.

On the inner peripheral surface sides of the concave portion 5 and the central rib groove 7 are formed, the end surfaces of the mounting base material 3 are abutted so as to contribute to the positioning of the exterior plate materials 2a and 2b. ,
A flat seat surface 8 is formed which extends orthogonally to the radial direction. In a state where the exterior plate materials 2a and 2b are assembled into a cylindrical shape, four seat surfaces 8 are formed at positions of 90 degrees on the inner peripheral surface side thereof, and these positions are formed on the four surfaces of the square pipe 1.
