Description

[Detailed description of the invention] The invention is a sighting board (hereinafter simply referred to as a board) useful for the exterior walls of buildings and structures.

) regarding. This type of board, which has traditionally been used, consists of a metal plate, a core material, and a waterproof sheet, and when they are connected to form a wall, rainwater can enter the interior through the connected parts due to capillary action, and wind pressure can cause problems. There was a drawback to leaving.

Furthermore, the width of the connecting portion is not uniform, resulting in poor appearance.

In order to eliminate these drawbacks, the present invention provides a stopper and a tongue piece to prevent capillary action on the male connector, and a fulcrum that contacts the stopper and adds elasticity to the insertion edge on the female connector. The present invention proposes a board in which elasticity acts mutually at the board connecting part by forming a protrusion that functions as a ridge to strengthen waterproofness and engagement force, and by having a tongue piece bite into the heat insulating material.

An embodiment of the board according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing the board.

In the figure, 1 is composed of a main body 2 made of a metal plate formed from a surface material and having a mesh-like cross section, and a male connecting part 6 and a female connecting part 10 formed at the lower ends of both side walls of the main body 2. It is.

To explain further, the main body 2 has a planar cross section formed from side walls 4 and 5, which are formed by inwardly bending both side edges of an elongated decorative surface 3 in the longitudinal direction.

In addition, the male connecting portion 6 extends the lower end of the side wall 4 downward, and has a stopper portion 7 whose tip is bent outward to form a U-shaped cross section, and an upper end edge of the stopper portion 7 is bent inward. death,
Next, it is formed from an insertion edge 9 having a tongue piece 8 which projects horizontally outward and whose tip is bent inward.

Furthermore, the female type connecting portion 10 bends the lower end of the side wall 5 inwardly,
Next, there is an insertion groove 11 which is bent outward to form an inverted U-shaped cross section, and an extension portion 1 whose lower edge 12 protrudes horizontally outward.
3, a protrusion 14 formed parallel to the side wall 5 in the middle, and a tongue piece 15 with the tip of the extension part 13 bent outward.

Reference numeral 16 is a heat insulating material having elasticity and filled in the space of the curved part of the main body 2 flush with the lower end of the plane. Examples of the heat insulating material include polyurethane foam (soft or hard), polyisocyanurate, etc. It is made of one or more synthetic resin foams such as foam, phenol foam, polystyrene foam, and vinyl chloride foam.

Note that the heat insulating material is not limited to the molded body, and can also be injected by foaming on site.

Furthermore, the heat insulating material 16 is made of synthetic resin foam at approximately 20 to 60 kg/m due to the relationship between heat insulating properties and mechanical strength such as bending and compression.
A density of 3 is preferable, and inorganic fibers have a density of 40 to 100 kg.
/m3 is preferred.

Reference numeral 17 is a flexible waterproof sheet, which covers the back side of the heat insulating material 16 as shown in the figure, and is stretched over the back side of the stopper section 7 and the back side of the insertion groove 11.

Note that the waterproof sheet 17 is usually attached to the back surface of the heat insulating material 16, the back surface of the stopper portion 7, and the lower edge 12 of the insertion groove 11 using an adhesive.

The waterproof sheet 17 is made of one or more of kraft paper, asbestos paper, asphalt felt, metal foil, synthetic resin sheet, etc., laminated together.

Of course, kraft paper or the like may be subjected to waterproof treatment, for example, impregnated with polyethylene or asphalt, or laminated.

Further, the waterproof sheet 17 not only serves as a waterproof layer to prevent corrosion of the heat insulating material, but also greatly contributes to improving mechanical strength by working with the main body 2.

To explain in detail the size of the board mentioned above, the length from the tip of the tongue piece 8 of the insertion edge 9 to the center of the stopper part 7 is A, and the length from the innermost part of the insertion groove 11 to the center of the protrusion 14 is The length is B, the length from the side wall 4 to the tip of the tongue piece 8 is C1, the length from the deepest part of the insertion groove 11 to the tip of the tongue piece 15 is D, the thickness of the insulation material 16 is T, the decorative surface 3 to the back surface of the extension part 13 is Hl, the height from the decorative surface 3 to the tip of the stopper part 7 is H2, and the height from the decorative surface 3 to the surface of the insertion edge 9 is H.
3. The height from the decorative surface 3 to the top surface of the insertion groove 11 is H4,
The height of the stopper part 7 is H5, that is, (H2-H3), the opening height of the insertion groove 11 is H6, the height of the protrusion 14 is H7, the height of the tongue piece 8 is H8, and the height of the tongue piece 15 is H6. Let the height be H9.

Therefore, to explain each dimension relationship, A>B, C<D, H
1≧H2, H32H4, Hs = He, H7≦H6,
H8≦H6, H9<Hs.

In particular, in this board, the stopper part 7 is designed to maintain a constant joint interval W when installed as shown in Fig. 2, and to ensure that a large gap S is formed to guide the board and prevent it from coming off, and to prevent rainwater from entering. This prevents capillary action.

In addition, the stopper portion 7 acts as a fulcrum during installation, and the connection can be made more securely and under elasticity.

Next, a construction example of the above-mentioned board will be described. As shown in FIG. 2, the board (2) is fixed to the trunk edge A via nails B.

Next, insert the insertion edge 9 of the adjacent board @ into the insertion groove 11 of the board ■.

Therefore, to form the wall, the above operations must be performed in sequence.
Just go.

In this case, the stopper part 7 contacts the extension part 13, and the surface of the insertion edge 9 contacts the upper surface of the insertion groove 11, so that pressure (reaction force) acts on each other.

Further, the waterproof sheet 17 and the tongue piece 15 are in contact with each other by compressing the heat insulating material 16 as shown in the figure, so that they maintain airtightness with each other.

Further, the protrusion 14 and the stopper portion 7 come into contact with each other, and further insertion into the insertion groove 11 is prevented.

Therefore, even if rainwater enters from the connecting portion, the large gap S acts as a vertical pipe, completely blocking capillary action.

Furthermore, since the heat insulating material 16 does not absorb moisture, its heat insulating performance does not deteriorate.

In addition, since the position of the nail is located at the end of the protruding piece as shown in the figure, there is no intrusion of moisture from the nail hole, and the stopper part 7 fixes the position where the span is not very long, so it is not supported. There is no problem with power.

What has been described above is only one embodiment of the board according to the present invention, and as shown in FIG. 3, a downward protrusion 9a may be provided in the middle of the insertion edge 9.

As mentioned above, according to the board according to the present invention, it is possible to construct a wall with a beautiful appearance while keeping the joint width constant, and
It has the characteristics of preventing rainwater from entering through the connecting parts, and effectively utilizing the balance of elastic forces in the connecting structure to prevent the boards from coming off.
