Description

  The present invention relates to a plate material for actually joining a male real part and a female real part formed in a longitudinal part by abutting each other.

  Conventionally, as shown in FIG. 7, a floor material 41, which is a plate material in which a male fruit 42 and a female fruit 43 are formed on the left and right longitudinal portions of a wooden base material, is well known. This floor material 41 is driven by nails from the base portion on the surface side of the male fruit 42 to fix the floor material to the floor base, and the female fruit 43 of another floor material 41 is attached to the male fruit 42 of the fixed floor material 41. The flooring 41 is pasted by fitting. In the flooring 41, the upper end surface 44 of the male fruit 42 and the end surface 45 of the protruding portion above the female fruit 43 are formed in a vertical plane, and the chamfered portion 47 is formed at the upper end corner of the upper end surface 44 and the end surface 45. , 46 are formed. In the state where the floor materials 41 and 41 are actually joined, the upper end surface 44 and the end surface 45 which are vertical surfaces are close to each other, and the decorative groove 48 is formed on the floor surface by the chamfered portions 46 and 47. (Patent Document 1).

  When the conventional flooring 41 shown in FIG. 7, particularly a solid flooring, is used as a flooring for floor heating, the flooring is shrunk by heat release and dried by heating, and the flooring A gap occurs in the actual joint. When a gap occurs in the actual joint portion, the conventional flooring 41 shown in FIG. 7 has the upper end surface 44 and the end surface 45 below the chamfered portions 46 and 47 formed as vertical surfaces, and the chamfered portions 46 and 47. Since the corner is formed between the upper end surface 44 and the end surface 45, the gap is conspicuous due to the corner, and the design is also deteriorated. It takes time and effort to get rid of it. Furthermore, when used for warm water floor heating, the shrinkage is further increased, and the actual situation is that it does not fit within the gap amount recommended by the gas company to be adopted (allowable amount of 0.5 mm or less when viewed from directly above). .

  Therefore, the floor material 51 shown in FIG. 8 has a male upper side inclined surface 53 from the base upper side of the male fruit 52 to the floor material surface 51a, and the upper side of the female fruit 55 from the upper edge to the male upper inclined surface 53. Even if the floor material 51 contracts and a gap is generated by providing a corresponding female actual upper inclined surface 56 and providing a chamfered portion 57 between the female actual upper inclined surface 56 and the floor material surface 51a. The gap is inconspicuous (Patent Document 2). However, since the floor 51 shown in FIG. 8 has the male upper inclined surface 53 formed from the floor 51 surface to the male 52, if the base material portion having a wide width W is not cut, In the rainy season in which the male upper inclined surface 53 cannot be formed and the humidity is high, the floor material 51 which is a wooden base material swells and the female upper inclined surface 56 becomes the male upper inclined surface. As a result, there is a case where a step is generated at the actual joint portion between the floor material 51 and the floor material 51.

  The purpose of the present invention is to actually join the plate materials as described above, and to solve the disadvantages of the conventional plate material, even if the plate material dries and shrinks, the gap generated by the shrinkage is reduced, and It is to provide a plate material to be actually joined that is made inconspicuous, can form a male part and a female part with a small cutting allowance, and does not cause a step between adjacent plate materials even if the floor material swells.

  The plate material of the present invention is a plate material in which a male part and a female part are formed in the left and right longitudinal parts of the plate material, and the upper part of the male part in the male part is inclined in the direction of the male part from the surface of the plate material An upper inclined surface is formed, and a substantially vertical upper end surface is formed between the lower end of the upper inclined surface and the base end of the male fruit, and the female real part includes an upper ridge part and A female fruit is formed with the lower ridge, and the upper ridge is formed with an upward slope formed at the upper corner and a lower face at the lower end of the upward slope. Formed on the lower slope of the downward slope, and a ridge end face that is nearly perpendicular to the lower slope, the lower end of the upper slope of the male part and the lower part of the female part The lower end of the inclined surface is the same height, and when the actual joint is made, the upper inclined surface of the male real part and the downward inclined surface of the female real part are in contact with each other. It is characterized in Rukoto.

  Therefore, in the plate material of the present invention, when the plate material is actually joined, a decorative groove is formed by the upper inclined surface of the male real part and the upward slope of the female real part, and a vertical surface is formed below the decorative groove. Therefore, even if a gap is generated between the upper inclined surface of the male real part and the downward slope of the female real part due to contraction of the plate material, the design is not impaired and is not easily noticeable. That is, when the decorative groove is viewed from above, the upper inclined surface and the upward inclined surface forming the decorative groove are seen, and a new surface does not appear due to the occurrence of the gap, so that the design property Will not get worse. Further, for example, even if the plate material contracts in the horizontal direction, the distance between the upper inclined surface of the male real part and the downward slope of the female real part can be made smaller than the amount of contraction of the plate material in the horizontal direction. It can be made less noticeable, and it is difficult for fine dust and dust collected in the gap to enter the back.

  In the plate material of the present invention, the upper end surface between the lower end of the upper inclined surface in the male part and the base part of the male part is formed substantially perpendicularly. The male part can be formed, the male part can be formed with a small machining allowance, and the female real part can be formed with a small machining allowance as well, so that the yield of the base material can be improved.

  Further, in the plate material of the present invention, the lower end of the upper inclined surface of the male real part and the lower end of the downward inclined surface of the female real part are the same height, and when the actual joint is made, the upper inclined surface of the male real part and the female Although it is in contact with the downward slope of the real part, it is configured so that the upper end surface of the male real part and the end face of the ridge part of the female real part are not in contact with each other. Even if the plate material that is the base material swells, the upper ridge portion of the female real part does not rise along the upper inclined surface of the male real part.

  Further, in the plate material of the present invention, the upward slope of the female real part is formed into a curved surface having a substantially round shape, and the upper slope of the male real part is a curved surface having a substantially round shape in cross section. It is comprised by the lower side slope which is and can give a soft taste on the external appearance, and can set it as the plate | board surface with a good touch.

  As can be understood from the above description, the shape of the decorative recess formed between the plate materials does not change much even if the plate material of the present invention shrinks due to drying or the like and a gap is generated between the plate materials actually bonded. Therefore, the design property is not impaired, and the generated gap is smaller than the gap generated in the conventional plate material, so that it is not noticeable, and the male part and the female part can be formed with less machining allowance. The yield of the substrate can be improved. Furthermore, according to the present invention, during the rainy season in which the humidity is high, even if the plate material that is the wooden base material swells, the upper ridge portion of the female real part may rise along the upper inclined surface of the male real part. Absent.

  Hereinafter, preferred embodiments of a floor material which is a plate material of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing the flooring of the present invention, FIG. 2 is a partially enlarged sectional view showing a joined state of the flooring of the present invention, and FIG. It is a partial expanded sectional view which shows a joining state when a clearance gap produces.

  As shown in FIG. 1, a floor material 1 formed of a wooden base material has male and female portions 2 and 3 for actually joining the floor material 1 by abutting the floor material 1 on both end faces in the longitudinal direction. . In the male part 2, a male fruit 4 is formed so as to protrude substantially at the center in the thickness direction of the flooring 1. Further, the male part 2 is formed with an upper inclined surface 5 that is inclined from the surface 1 a of the flooring 1 in the direction of the male fruit 4, and between the lower end of the upper inclined surface 5 and the base part of the male fruit 4. An upper end face 6 is formed in the upper part.

  The upper inclined surface 5 has an inclination angle of approximately 45 degrees, and the portion of the upper inclined surface 5 near the surface 1a also functions as a member that forms the decorative groove 18 when the flooring materials 1 and 1 are actually joined. ing. The upper end surface 6 may be a vertical surface, or may be larger than 90 degrees so that the surface faces downward. When larger than 90 degrees, the nail can be driven closer to the center of the flooring. In addition to preventing cracking of the plate, a space for the nail head can also be formed.

  A lower end surface 7 that forms a substantially vertical surface is formed in the lower part of the male fruit 4, and the lower end surface 7 is located on the distal end side of the male fruit 4 from the base on the upper surface of the male fruit 4. For example, even if the nail is driven into the base of 4 at a large angle of about 65 degrees, for example, the crack of the male 4 is reduced, and the allowable range of the nail driving angle can be widened.

  In the female real part 3, a female fruit 10 is formed by an upper ridge part 11 and a lower ridge part 12. An upper slope 13 is formed at the tip of the upper ridge portion 11 of the female fruit 10, and this upward slope 13 is a male fruit in the other floor material 1 when the floor material 1 is actually joined. A shallow groove 18 for decoration is formed by the portion near the surface 1 a of the upper inclined surface 5 of the portion 2.

  A downward slope 15 whose surface is directed downward is formed at the lower end of the upward slope 13, and chamfering is applied to the tip portions of the upward slope 13 and the downward slope 15. The downward slope 15 is in contact with the upper inclined surface 5 of the male part 2 when the flooring 1 is actually joined, and the lower end thereof coincides with the lower end of the upper inclined surface 5. The length of the downward slope 15 is determined in consideration of the amount by which the flooring 1 shrinks due to drying or the like. A ridge end surface 16 is formed at the lower end of the downward slope 15, and the lower end of the ridge end surface 16 is located closer to the base, and the lower end of the downward slope 15 and the upper inclined surface 5 The lower end is made easy to coincide with the lower end, and a space for accommodating the nail head of the nail for fixing the flooring is formed.

  The flooring 1 of the present invention is configured such that, when the flooring 1 is actually joined, a decorative groove 18 is formed by the upper slope 5 of the male part 2 and the upward slope 13 of the female part 3. No vertical surface is formed below the decorative groove 18. Therefore, unlike the conventional floor material 41 shown in FIG. 7, since the corner is not formed between the chamfered portions 46 and 47 and the vertical surface, the floor material 1 contracts and the upper slope of the male part 2 is inclined. Even if a gap is generated between the surface 5 and the downward slope 15 of the female real part 3, the design is not impaired and is not conspicuous. That is, when the decorative groove 18 is viewed from above, the upper inclined surface 5 and the upward inclined surface 13 forming the decorative groove 18 are viewed, and a new surface appears due to the gap. Therefore, the design property does not deteriorate. Further, for example, even if the floor materials 1 and 1 contract 1 mm in the horizontal direction and a gap H is generated by 1 mm between the upper end face 6 of the male real part 2 and the ridge end face 16 of the female real part 3, Since the distance h between the upward slope 5 of 2 and the downward slope 15 of the female real part 3 is 0.88 mm, the gap generated between the floor materials 1 and 1 is larger than the amount of contraction of the floor materials 1 and 1. The gap can be made even less conspicuous, and fine dust or dust collected in the gap is less likely to enter the interior.

  In the flooring of the present invention, the upper end face 6 between the lower end of the upper inclined surface 5 and the base part of the male fruit 4 in the male part 2 is formed substantially vertically, so that it is narrow as shown in FIG. If the base material part of the width w is cut, the male part 2 can be formed, and the male part 2 can be formed with a small cutting allowance. Similarly, since the female real part 3 can also be formed with a small cutting allowance, compared with the flooring 51 shown in FIG. The male real part 2 and the female real part 3 can be formed, and the yield of a base material can be improved.

  Further, the flooring of the present invention is formed by the upper inclined surface 5 and the upper end surface 6 in the male part 2 even when the flooring 1 as the wooden base material swells during the rainy season when the humidity is high. Since the corner portion is in contact with and pressed against the corner portion formed by the downward slope 15 and the ridge end face 16 in the female real portion 3, the upper ridge portion 11 of the female real portion 3 is the male real portion 2. Therefore, no step is generated between the floor materials.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention described in the claims. The design can be changed. In the above embodiment, the upper inclined surface 5 of the male part 2 and the upward slope 13 of the female part 3 are formed in a plane. However, as shown in FIG. The upper inclined surface 5 may be formed as a curved surface, the upper portion 5a functioning as a decorative groove 18 may be a curved surface having a substantially rounded cross section, and the lower portion 5b below the upper portion 5a may be configured as a flat surface. When the upward slope 13 and the upper portion 5a of the upper inclined surface 5 are formed in a curved surface having a substantially rounded cross section, it is possible to provide a soft and soft taste and to have a touch-sensitive plate surface.

  Further, as shown in FIG. 5, the upper inclined surface 5 is formed by an upper plane 5c of a portion functioning as a decorative groove 18 and a lower plane 5d below the upper plane 5d, and the lower plane 5d is substantially cross-sectionally cut. If it is configured to be continuous as a slope closer to the horizontal than the upper plane 5c via the rounded curved surface 5e, no corner is formed between both planes 5c and 5d, so there is no sense of incongruity and even if the plate material contracts Further, the gap can be further reduced, and dust and the like accumulated in the gap can be further prevented from falling down. As shown in FIG. 6, when the upper inclined surface 5 is formed on the flat surface 5f at the portion functioning as the decorative groove 18, the upper portion is formed on the curved surface 5g having a substantially rounded cross section. The edge part of the inclined surface 5 can be made into a surface nearer horizontal. Furthermore, in the said embodiment, although demonstrated about the flooring, the board | plate material of this invention will be a ceiling board and wall material, if the real part and the female real part are formed in the both-sides edge part, and it joins actually. Of course, it may be a plate material. Moreover, the board | plate material may laminate | stack and adhere | attach a thin MDF and a ground plate on the surface of a solid material or a baseboard plywood.
