[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a siding board (hereinafter simply referred to as a board) useful for forming internal and external walls of buildings and structures. [Prior art] This type of board that has been used in the past includes Tokoku No. 51-29339, Utility Model No. 51-11882,
There is Jikko No. 54-26649. however,
There were various problems with the above board. In other words, if rainwater is blown by the wind on the board (closing board), the rainwater will leak to the back side because it is simply a connecting structure between flat plates, corroding the edges and pillars, and causing moisture in the room and closet. There were some drawbacks. In addition, the length of the sloped part of the lower edge to the rising part of the board is long, so it is weak against tensile force.
The disadvantage was that only an exterior without joints could be formed.
Moreover, although the exterior was originally without joints, due to the skill of the builder, the exterior was made up of joints of varying widths, some without joints, some with joints, and there was a risk of injury from the rising parts during construction. Furthermore, the board had a complicated side shape, making it difficult to mold and expensive. [Purpose of the invention] In order to eliminate the above-mentioned drawbacks, the present invention forms a female type connecting part on one end edge of the decorative surface and a male type connecting part on the other end edge, and a cover piece and a cover piece are formed on the female type connecting part. A protruding piece, an insertion groove, and a fitting groove are provided, and the male connecting part is provided with a depression, an insertion edge, and an engagement groove, and the connection structure of the board is connected to the tip of the cover piece, the depression, and the insertion groove. The four-layer structure of the groove and insertion edge, the protruding piece and the engagement groove, and the engagement groove and the lower edge greatly strengthens the waterproofness, engagement force, and sealing performance of the connecting part of the board, and also increases the mechanical strength of the board. A core material that prevents warping and twisting, has heat insulating and fireproof properties, and bulges out below the surface material.
By placing it at the bottom of the joint area, it passes various tests such as fire prevention tests.Moreover, when this board is used as a horizontal lining, it can be easily installed by one worker, and requires no skill. It can be done without
Furthermore, the present invention proposes a board that can also be used for vertical installation.

and the tip of the recess 14 is directed outward at an angle θ ₄ with the side wall 13.
(θ ₄ ≒ θ ₃ ), and the tip of the insertion edge 15 is bent inward, and then the lower edge 17 is bent outward to form an almost U-shaped cross section. It is formed from an engaging groove 16 which is curved, and a tongue piece 18 which is bent at the tip of the lower edge 17 into a seam shape. That is, the tip of the cover piece 5 of the female connecting part 3 is inserted into the recessed part 14, and the insertion edge 15 is inserted into the insertion groove 7.
In addition, the lower edge 17 engages with the fitting groove 8,
Further, the engagement groove 16 is for inserting the protruding piece 6. By making the connection structure of board A fourfold in this way, the engagement force and sealing performance of the connection part are improved, and even if board A is slightly deformed in the event of a fire, the connection part will not come off. Fire protection is improved by preventing flames and hot air from entering the wall. Furthermore, since the circulation of air between the inside and the outside of the wall is prevented, the core material 19, which will be described later, has the characteristic of fully exhibiting its heat insulation performance. Furthermore, the cover piece 5 and the recess 14
Due to the connection, a clear dividing line appears between the side wall 13 and the cover piece 5, the joint is emphasized, and the three-dimensional space between the boards A is promoted. Further, the tongue piece 18 prevents the tip of the lower edge 17 from waving, helps to smoothly insert the lower edge 17 into the fitting groove 8, and improves work safety similarly to the tongue piece 11. It is something. Note that the tongue piece 18 does not need to sandwich one end of the backing material 20 as shown in FIG. 1, or may be formed into a bottom flap shape so that the tongue piece 18 does not need to sandwich the backing material 20. The core material 19 is filled in a gutter-shaped part surrounded by the decorative surface 2, the female connecting part 3, and the male connecting part 12 on the back side of the surface material 1 , and is disposed so as to bulge downward. It imparts heat insulation and fireproof properties to A, and is made of one type of material that additionally has functions such as adhesiveness, cushioning properties, and soundproofing properties. Specifically, it consists of one type of synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, etc., and it consists of something that is discharged with raw materials, molded, hardened, self-adhesive, or a molded body. It is something. To explain further, the core material 19 bulges downward from the surface material 1 , and a notch 19a is formed in the vicinity of the male connecting portion 12. When the boards A are connected, the extension part 10 of the female connecting part 3 comes into contact with this notch 19a, and the board A
The back surface is a flat surface with no gaps, and the wall base is entirely covered with a core material 19 having heat insulating and fireproof properties. For this reason, the core material 19 is also provided at the bottom of the joint part of board A, improving the fire resistance of the joint part, which is a weak point in terms of fire prevention, and in the event of a fire, the above-mentioned female joint part 3 and male The four-fold connection structure with the mold connection part 12 prevents flames and hot air from entering the wall, making it possible to pass various fire protection tests. Note that when a molded body is used, an adhesive (not shown) is required between the core material 19, the surface material 1 , and the back material 20. In addition, as the core material 19, synthetic resin foams are mainly used, such as resins for polyurethane foam, resins for phenol foam, resins for polyisocyanurate foam, and flame retardants, etc.
