嵌合溝３ｂが形成されて構成されている。As shown in FIG. 1B, as male and female connecting portions 2 and 3 for connecting siding materials, the male connecting portion 2 protrudes toward the middle portion in the thickness direction and is folded. A nailing piece 2b projecting further outward at the lower end in the width direction is formed via a U-shaped connecting portion 2c, and the female connecting portion 3 is bent vertically. The upper end face 3a is formed with a U-shaped fitting groove 3b which is continuously opened to the side.

という問題がある。However, when a wall is constructed by connecting siding materials, it is necessary to cover the male connecting portion 2 so that the female connecting portion 3 is straight down. There is a problem that it is difficult to perform the construction because it easily interferes with the base material.

It is necessary to fine-adjust the material by moving it to the left and right, but the protruding piece 2a of the male connecting portion 2 and the fitting groove 3b of the female connecting portion 3 are in close contact, making it difficult to make fine adjustments. However, there is also a problem that fine adjustment is more difficult because the length of the siding material is usually as long as about 4 m.

いなど、種々のメリットがある。In the manufacturing process of the siding material, the surface material is formed in a substantially gutter shape (the surface material 11 is used as the product siding material 10).
When the surface of is upward, it is formed in a substantially reverse gutter shape. )
When the foaming stock solution of the synthetic resin foam is injected into the recess with the opening facing upward and solidified to form a filler, it is preferable to use a back material. Even if the edge of the back material is positioned on the back side of the male-female connection portion so as to cover the entire back surface of the siding material 10 (see FIG. 1), one end edge of the back material is sandwiched between the male-female connection portion ( (See FIG. 3). In particular, if one end of the back material is located inside the female connection part, the foaming pressure of the synthetic resin foam does not directly act on the male and female connection part, and there is an obstacle to insertion of the lower holding part at the time of wall construction. There are various advantages, such as not being messy.

にできるようにしてある。The distal end of the lower holding portion 13d is bent upward or downward to form an arc shape so that the female connecting portion 13 can be safely handled when the siding material 10 is transported or constructed. In the connecting portion 13, the arc-shaped bent portion functions as a guide portion 13 e, and is formed on the inner surface of the nailing piece 12 d and the outer surface of the lower end surface portion 12 c at the time of fitting connection with the male connecting portion 12. It is designed to facilitate connection work by following.

形状はこの略鍵穴形状が最も好ましい。In such a female connecting portion 13, a horizontal upper holding portion 13b and a downwardly inclined lower holding portion 13d are connected by a substantially C-shaped guide recess 13c. The distance between the lower holding portion 13d and the leading end of the opening is widened and gradually narrowed, and becomes the narrowest at the connecting portion between the lower holding portion 13d and the guide recess 13c.
It is in a state where it has spread again in c. The shape of the female connecting portion 13 is most preferably this substantially keyhole shape.

となる。Since the upper holding portion 13b and the lower holding portion 13d of the female connecting portion 13 are connected to each other by sandwiching the protruding portion 12b of the male connecting portion 12 at the narrowest portion between the upper holding portion 13b and the lower holding portion 13d. The connecting work can be performed by inclining the material 10 toward the operator, the insertion of the protruding portion 12b and the lower holding portion 13d becomes easy, and since there are few contact portions, it is easy to slide in the length direction, and the alignment is performed. Becomes easier.

端を乗り越えたとしても、下地材に至ることはない。After the siding material 10 is connected to form a wall surface, if a typhoon or the like is subjected to strong wind and rain, a negative pressure is generated on the wall surface, and the siding material 10 tends to peel off, but the upper holding portion 13b and the guide recess 13c are formed. The spring effect (substantially C-shaped shape effect) due to the shape of the lower holding portion 13d, and the tip of the lower holding portion 13d has a nailing piece 12d or a lower end surface 1

With the support effect that the connecting portion with the contacting the protruding portion 12b,
A strong fit is maintained. Further, when the joint portion in the fitted state is exposed to wind and rain, rainwater tends to enter the interior due to a capillary phenomenon in a gap between the projecting portion 12b and the upper holding portion 13b. The capillary action can be cut off in the space defined by the above, and even if the rainwater gets over the tip of the protruding portion 12b due to the wind pressure, it does not reach the base material.

好ましい。The downward inclination angle of the lower holding portion 13d of the female connecting portion 13 is preferably 5 to 45 degrees with respect to the flat portion 11a. If the angle is less than 5 degrees, the upper end surface 13a of the female connecting portion 13 will be protruded 12b
The upper end surface 13a may be damaged, and if the angle is 45 degrees or less, the lower holding portion 13d becomes nearly horizontal when tilted toward the front, and the connecting operation is difficult depending on the length relationship of the lower holding portion 13d. May be. Lower holding part 13d
When the inclination is extremely large, for example, 90 degrees (vertical), the strength of itself is increased, but the holding force against the negative pressure is solely due to the effect of the guide recess 13c.
The same applies to 0 degree (horizontal), and the angle is preferably 5 to 45 degrees in order to exhibit the spring effect due to the shape of the upper holding portion 13b, the guide concave portion 13c, and the lower holding portion 13d and to enhance the connection workability.

In this way, the nails must be straightened down and connected, and the tip of the female connecting portion hits the nailing piece, making it difficult to fit and requiring a lot of manpower. However, any one end in the length direction is easily engaged, so that the lower holding portion 13d can be easily inserted,
Further, the connection can be easily performed only by standing up.

In the case of 0, the upper part is fixed by nails and screws, and the lower part is supported by the male and female connecting parts 12 and 13. However, when wind pressure or the like acts, the upper and lower holding parts 13b and 13d are substantially circular guides. Because they are connected via the recess 13c,
A spring force is applied to the upper and lower clamping portions 13b and 13d by the guide recess 13c to narrow each other, and a larger holding force than the conventional U-shaped vertex which is bent to be a fulcrum. Can be obtained, the connection can be made firmly, and a thin surface material can be used.
