The width is 143 mm, and the length varies depending on the position where it is arranged. That is, the wall materials A, B, and C all have the same width, the wall material A and the wall material B have the same thickness but different lengths, and the wall material C is thicker than the wall materials A and B. It is thinner than these and has a length that is not fixed and is appropriately cut from the original size of 900 mm.

Further, all of these wall materials A, B, and C have a structure in which MDF is used as a base material and a wood grain decorative sheet is attached to at least the surface thereof, but the shape of the base material and the attached state of the decorative sheet are different. , Wall materials A and B and wall material C are different. This point will be described with reference to FIG. 2 which is a six-view view of the wall materials A and B and FIG. 3 which is a six-view view of the wall material C.

First, the shape of the base material will be described. Males 13 and females 14 are formed along a pair of long sides of the base materials 12 of the wall materials A and B, and the back side (wall base) is formed along the pair of short sides. The notches 15 and 15 are formed on the side in contact with 11), while the male and female 18 are formed along the pair of long sides of the base material 16 of the wall material C, and the pair of shorts are formed. Males 19 and females 20 are formed along the sides. The male fruit 13 and female fruit 14 formed along the long sides of the wall materials A and B and the male fruit 17 and female fruit 18 formed along the long side of the wall material C are at the same position (from the back surface). It is formed in a shape that can be fitted to each other (position in the thickness direction). Further, as for the dimension of the notch 15 formed on the back surface side along the pair of short sides of the base materials 12 of the wall materials A and B, the dimension d1 in the short side direction is the protruding length of the male fruit 17 of the wall material C. It is set to be sufficiently larger than that, and the dimension d2 in the thickness direction is set to be substantially equal to the distance to the surface of the male fruit 17 of the wall material C.

Next, the state in which the decorative sheet is attached to the wall materials A, B, and C will be described. In the wall materials A and B, the surface and the four side surfaces (male 13, female 14, and notch 15) of the base material 12 are formed. The wood grain decorative sheet 21 is attached to the surface of the base material 12 to be removed), whereas the wall material C has the same decorative sheet 22 attached only to the surface of the base material 16. The decorative sheet 22 is not attached to the side surface, and the end surface of the base material 16 is exposed.

Note that FIG. 3 shows the wall material C having a length of 900 mm before cutting, and as described above, when the wall surface structure 10 is constructed, it is cut to an appropriate length and used. ..

4 to 8 are cross-sectional views showing a state in which the short sides of the wall material are connected to each other in the wall surface structure 10 of FIG.

FIG. 4, which is a cross-sectional view taken along the line AA in FIG. 1, shows a short-sided connection state between the wall materials C. Since male fruits 19 and female fruits 20 are formed on the wall material C along a pair of short sides, the wall materials C can be closely fitted along the short sides through these fittings. it can. In this connecting portion, the wood end surface, which is the non-attached surface of the decorative sheet of the wall material C, is not exposed, so that the design is not deteriorated, and the decorative sheets 22 attached to the surface of the wall material C are continuous. Gives a cosmetic surface. When the wall materials C are connected to each other along the short side, the male fruit 19 and the female left on the side opposite to the cut surface in the length direction in the wall material (end material) corresponding to the end portion of the original wall material C. It is preferable that the fruit 20 is utilized and connected via actual fitting as shown in FIG.

FIG. 5, which is a cross-sectional view taken along the line BB in FIG. 1, shows a short-sided connection state between the wall material B and the wall material C after the length is cut. Since the wall material B is formed with notches 15 having the shape and dimensions along the pair of short sides, the surface side of the base material end surface of the wall material C from which the male fruit 19 has been cut is the side surface of the wall material B. The decorative sheet 22 attached to the surface of the wall material C and the decorative sheet 21 attached to the side surface and the surface of the wall material B, which is covered with the decorative sheet 21 attached to the wall material C so that the end surface of the wood is not exposed. And continuously give a cosmetic surface.

FIG. 6, which is a cross-sectional view taken along the line CC in FIG. 1, shows a short-sided connection state between the wall material B and the male fruit 19 side of the wall material C. As shown in FIG. 3, since fruits are formed on the four sides of the original wall material C, even the wall material C after cutting the length corresponds to the end portion of the original wall material C. In the wall material C, the fruit is left on the side opposite to the cut surface. Even when the wall material C in which the fruit (male 19) remains is connected to the wall material B in this way, the notch 15 having the shape and dimensions is formed in the wall material B along a pair of short sides. Therefore, the male fruit 19 of the wall material C can be accommodated in the notch 15, and the decorative sheet 21 attached to the side surface of the wall material B is the non-adhesive surface of the decorative sheet of the wall material C. Since the wood end surface is covered, the wood end surface is not exposed, and the decorative sheet 22 attached to the surface of the wall material C and the decorative sheet 21 attached to the side surface and the surface of the wall material B are continuously made up.

As is clear from these figures, the connection between the long sides of the wall material is, in any case, through the mating of the male and female fruits formed along the long sides of the wall material. Will be done.

FIG. 9, which is a cross-sectional view taken along the line EE in FIG. 1, shows a state in which the wall materials C are connected to each other on the long sides. Since male fruits 17 and female fruits 18 are formed on the wall material C along a pair of long sides, it is possible to fit the wall materials C to each other closely along the long sides through these fittings. it can. In this connecting portion, the wood end surface, which is the non-attached surface of the decorative sheet of the wall material C, is not exposed, so that the design is not deteriorated, and the decorative sheets 22 attached to the surface of the wall material C are continuous. Gives a cosmetic surface.

FIG. 10, which is a sectional view taken along line FF in FIG. 1, shows a state in which the wall material B and the wall material C are connected to each other on the long side. Here, the wall materials B and C are tightly fitted along the long side through the fitting of the female fruit 14 of the wall material B and the male fruit 17 of the wall material C. In this connecting portion, the wood end surface, which is the non-attached surface of the decorative sheet of the wall material C, is not exposed, so that the design is not deteriorated, and the decorative sheet 22 attached to the surface of the wall material C and the wall material The decorative sheet 21 attached to the side surface and the surface of B continuously gives a decorative surface.

FIG. 11, which is a sectional view taken along line GG in FIG. 1, shows a state in which the wall material A and the wall material C are connected to each other on the long side. Here, the wall materials A and C are tightly fitted along the long side through the fitting of the male fruit 13 of the wall material A and the female fruit 18 of the wall material C. In this connecting portion, the wood end surface, which is the non-attached surface of the decorative sheet of the wall material C, is not exposed, so that the design is not deteriorated, and the decorative sheet 22 attached to the surface of the wall material C and the wall material The decorative sheet 21 attached to the side surface and the surface of A continuously gives a decorative surface.

FIG. 12, which is a cross-sectional view taken along the line HH in FIG. 1, shows a state in which the wall material A and the wall material B are connected to each other on the long sides. Here, the wall materials A and B are tightly fitted along the long side through the fitting of the male fruit 13 of the wall material A and the female fruit 14 of the wall material B. In this connecting portion, the decorative sheets 21 attached to the surfaces of the wall materials A and B continuously give a decorative surface.

Note that the wall material A and the wall material B differ only in length, and the conditions such as the shape and thickness including the notch 15 are exactly the same. Therefore, in FIGS. 4 to 12, the wall material A is the wall material B. Alternatively, or when the wall material B is replaced by the wall material A, the connection state is the same as shown in the drawing.

In the wall surface structure 10, generally, a plurality of wall materials A to C are connected to each other to form a row as shown in FIGS. 4 to 8, and further, as shown in FIGS. 9 to 12. By actually fitting the long sides of the wall materials A to C constituting each row, a plurality of rows are connected in the vertical direction. In this case, the width dimension of the wall surface structure 10 is arbitrarily set, and the length of the wall material C is cut accordingly, but the height dimension is the common width of the wall materials A to C (this embodiment). 143 mm) multiplied by the number of rows (6 in this embodiment). However, since male fruits 13, 17 and female fruits 14, 18 are formed along the long sides of the wall materials A to C, either the upper or lower side of the wall surface structure 10 thus formed is formed. Males 13 and 17 formed along the long sides of the wall materials A to C forming the uppermost or lowermost row are left on the side edges in a protruding state, which spoils the aesthetic appearance. Therefore, it is preferable to excise the males 13 and 17. However, when the male fruit is excised, the base material surface is exposed. In order to hide this, the wall surface structure 10 in FIG. 1 has a side covering piece 23a and a surface covering piece 23b and has an L-shaped cross section. The edge material 23 formed in is used. By using the rim material 23, not only the exposure of the base material surface after excision of the male seeds is prevented, but also the female seeds 14, 18 and 20 of the wall materials A to C exposed on the outer peripheral edge of the wall surface structure 10 are concealed. It is effective in enhancing the aesthetics. The rim material 23 may be formed of any material, but in this embodiment, a wood material is used, and a fixture 24 such as a nail or a staple is driven into the wall base so as to cover the side surface from the surface end portion of the wall material. It is fixed to the base of the wall. When fixing the edge material 23, an adhesive, double-sided tape, or the like may be used in combination. Further, the height of the edge member 23 is substantially the same as the thickness of the wall members A and B (12 mm in this embodiment).

FIG. 13, which is a cross-sectional view taken along the line JJ in FIG. 1, shows an arrangement state of the edge member 23 in the vertical cross section in which the wall material C is located at both ends. As shown in the lower part of the figure, when the female fruit 18 of the wall material C is present on either the upper or lower edge of the wall surface structure 10, it does not interfere with the edge material 23, so that the surface of the wall material 23 is directly covered by the side covering piece 23a. The side surface can be completely covered from the end portion, whereby the female fruit 18 can be reliably concealed by the side surface coating piece 23a and the surface coating piece 23b. When the male fruit 17 is present on either the upper or lower edge of the wall material C, as shown in the figure, this is cut off to make a flat surface, and then the surface edge of the side covering piece 23a of the edge material 23 is used. It is provided so as to completely cover the side surface from the part. As a result, the base material surface 17'of the wall material C that appears after the male cutting can be reliably concealed by the side covering piece 23a and the surface covering piece 23b.

FIG. 14, which is a cross-sectional view taken along the line KK in FIG. 1, shows an arrangement state of the edge member 23 in the vertical cross section in which the wall members A and B are located at both ends. As shown in the lower part of the figure, when the females 14 of the wall materials A and B are present on either the upper or lower edge of the wall surface structure 10, they do not interfere with the edge material 23, so that the side covering piece 23a of the edge material 23 is used as it is. The side surface can be completely covered from the surface edge portion, whereby the female fruit 14 can be reliably concealed by the side surface coating piece 23a and the surface coating piece 23b. When the male fruit 13 is present on either the upper or lower edge of the wall materials A and B, as shown in the figure, the male fruit 13 is cut off to make a flat surface, and then the side covering piece 23a of the edge material 23 is used. Completely cover the sides from the surface edges. As a result, the base material surfaces 13'of the wall materials A and B appearing after the male cutting can be reliably concealed by the side covering piece 23a and the surface covering piece 23b.

FIG. 15, which is a cross-sectional view taken along the line LL in FIG. 1, shows the edge member 23 in the left-right cross section in which wall materials A and B (the same applies when both ends are wall material A or wall material B) are located at both ends. Indicates the arrangement state. Since the edge member 23 is provided so as to completely cover the side surface from the surface end portion of the wall members A and B with the side surface covering piece 23a, the notch 15 can be concealed.

FIG. 16, which is a sectional view taken along line MM in FIG. 1, shows an arrangement state of the edge member 23 in the short side cross section in which the wall member C is located at both ends. As shown on the left side of the figure, when the female 20 of the wall material C is present on either the left or right edge of the wall surface structure 10, it does not interfere with the edge material 23, so that the surface is directly covered by the side covering piece 23a of the edge material 23. It can be provided so as to completely cover from the end to the side surface, whereby the female seed 20 can be reliably concealed. When the male fruit 19 of the wall material C is present on either the left or right edge of the wall surface structure 10, it is cut off to make a flat surface as shown on the right side of the figure, and then the side covering piece of the edge material 23 is formed. 23a is provided so as to completely cover the side surface from the surface edge. As a result, the base material surface 19'of the wall material C that appears after the male cut can be reliably concealed.

When the height of the edge material 23 is substantially the same as the thickness of the wall materials A and B, the wall materials A and B are substantially in close contact with the surface end portions thereof (FIGS. 14 and 15). However, for the wall material C thinner than these, it is located away from the surface (FIGS. 13 and 16). However, by sufficiently increasing the inward protrusion length of the surface covering piece 23b of the edge material 23, the end portion of the wall material C can be reliably concealed and the appearance can be maintained well.

When the rim material 23 is used as in the first embodiment, if the inward protrusion length of the surface coating piece 23b of the rim material 23 is sufficiently large, it is not always necessary to cut off the male fruit appearing on the outer circumference, and the rim material It is not necessary to bring the 23 into close contact with the side surface of the wall material, and there may be a gap. This state is shown in FIGS. 17 to 20. These figures correspond to FIGS. 13 to 16 in the first embodiment, respectively.

In the vertical cross section shown in FIG. 17, a gap 25 is opened between the side surface of the wall material C (having the female fruit 18) located at the lower end of the wall surface structure 10 and the side covering piece 23a of the edge material 23. However, the gap 25 is concealed by projecting the edge member 23 inward by a sufficient length. Further, in this embodiment, the tip surface of the male fruit 17 is left as it is without being cut off from the male fruit 17 of the wall material C located at the upper end of the wall surface structure 10, and the tip surface of the male fruit 17 is inside the side covering piece 23a of the edge material 23. Although it is abutted against the side surface, by projecting the surface coating piece 23b of the edge material 23 inward for a sufficient length, between the side surface of the wall material C and the inner side surface of the side surface coating piece 23a of the edge material 23. The gap 26 can be concealed.

In the vertical cross section shown in FIG. 18, there is a gap 27 between the side surface (having the female fruit 14) of the wall material A or the wall material B located at the lower end of the wall surface structure 10 and the side covering piece 23a of the edge material 23.
