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.

  This invention is for solving the said subject, and this invention is the board | plate material in which the male part and the female real part are formed in the right-and-left longitudinal part of a board | plate material, In the upper part of the male part in a male part, it is this invention. An upper inclined surface that is inclined in the male direction from the surface of the plate material is formed, and a downward inclined surface is formed at the lower end of the upper inclined surface. An upper end face is formed between the base and the female part, and a female part is formed by an upper ridge and a lower ridge, and an upper corner of the upper ridge is directed upward. An inclined surface is formed, and a ridge end surface is formed at the lower end of the upward inclined surface, and the lower end of the downward inclined surface of the male real part and the lower end of the upward inclined surface of the female real part Are substantially the same height, and are configured so that the downwardly inclined surface of the male part and the upwardly inclined surface of the female part come into contact when actually joined. A plate material characterized by and.

  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 inclined surface of the female real part, and is perpendicular to the lower part of the decorative groove. Since the surface is not formed, even if a gap occurs between the upward inclined surface of the female real part and the downward inclined surface of the male real part due to contraction of the plate material, the design is not impaired, The generated gap is smaller and less conspicuous than the conventional one. That is, when looking at the decorative groove from above, you will see the upper inclined surface and the upward inclined surface forming the decorative groove, and a new surface will not appear due to the gap, The design is not deteriorated. Further, for example, even if the plate material contracts in the horizontal direction, the interval between the upward slope of the male part and the downward slope of the female part can be made smaller than the contraction amount 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.

  Furthermore, according to the present invention, the base end portion of the male body is formed inside the plate material by the downward inclined surface in the male body portion, and the male body portion is formed by cutting a base portion having a narrow width. Thus, the male part can be formed with a small machining allowance, and the female part can also be formed with a small machining allowance, so that the yield of the base material can be improved.

  Furthermore, in the plate material of the present invention, even when the plate material that is a wooden base material swells during the rainy season when the humidity is high, the upper ridge of the female body part is the downward inclined surface and the upper surface of the male body part. Since there is no gap between the plate members, no step is generated.

  Furthermore, in the plate material of the present invention, the upper inclined surface of the male real part is formed in a curved surface having a substantially round shape in cross section, and the upward inclined surface of the female real part is a curved surface having a substantially round shape in cross section; It is comprised by the lower side slope which is a plane, can give a soft taste on an external appearance, and can be set as the board surface which has 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, in the rainy season in which the humidity is high, the present invention provides that the upper protrusion of the female part is formed between the downward inclined surface of the male part and the upper surface of the male part even if the board material that is the wooden base material swells. Since it is in a state of being sandwiched between, there is no step between the plate materials.

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

  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 in the middle of 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 the surface is directed downward at the lower end of the upper inclined surface 5. A downward inclined surface 6 is formed. Chamfering is applied to the tip portions of the upper inclined surface 5 and the downward inclined surface 6. The length of the downward inclined surface 6 is determined in consideration of the amount of shrinkage of the flooring 1 due to drying or the like. An upper end surface 7 is formed between the lower end of the downward inclined surface 6 and the base of the male fruit 4, and a lower end surface 8 forming a substantially vertical surface is formed at the lower part of the male fruit 4. . The upper end surface 7 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. The lower end face 8 is located on the distal end side of the male fruit 4 from the upper end face 7, and even if a nail is driven into the base part of the male fruit 4 at a large angle of, for example, about 65 degrees, the crack of the male fruit 4 is reduced. The allowable range of the nail driving angle can be widened.

  In the female real part 3, a female real 9 is formed by an upper ridge 10 and a lower ridge 11. The upper ridge 10 of the female fruit 9 has an upward inclined surface 12 formed at the upper corner, and a ridge end surface 13 is formed at the lower end of the upward inclined surface 12.

The upward inclined surface 12 has an inclination angle of approximately 45 degrees, and the portion near the surface 1a in the upward inclined surface 12 can be used as a member that forms the decorative groove 18 when the flooring materials 1 and 1 are actually joined. The lower part is in contact with the downward inclined surface 6 of the male part 2 when the floor material 1 is actually joined, and the lower end thereof substantially coincides with the lower end of the downward inclined surface 6.
The ridge end face 13 is positioned so that the lower part is located closer to the base, and a space is formed between the upper end face 7 of the male part to accommodate the nail head of the nail for fixing the flooring. ing.

  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 inclined surface 5 of the male part 2 and the upward inclined surface 12 of the female part 3. The vertical surface is not formed below the decorative groove 18. Therefore, since the corner | angular part is not formed between the chamfering parts 46 and 47 like the conventional flooring 41 shown in FIG. 7, and a perpendicular | vertical surface, the flooring 1 of this invention contracts and the male part 2 Even if a gap is generated between the downwardly inclined surface 6 and the upwardly inclined surface 12 of the female real part 3, the design property is not impaired, and the clearance is not conspicuous. That is, when the decorative groove 18 is viewed from above, the upper inclined surface 5 and the upward inclined surface 12 forming the decorative groove 18 are viewed, and a new surface appears even if a gap is generated. Therefore, the design property does not deteriorate. Further, for example, even if the floor materials 1 and 1 contract in the horizontal direction by 1 mm and a gap H is generated by 1 mm between the upper end surface 7 of the male real part 2 and the ridge end face 13 of the female real part 3, the male part The distance h between the downwardly inclined surface 6 of 2 and the upwardly inclined surface 12 of the female part 3 is 0.88 mm, and 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 less noticeable, and fine dust or dust collected in the gap is less likely to enter the interior.

  In the floor material of the present invention, the base end portion of the male fruit 4 is formed on the inner side of the floor material by the downward inclined surface 6 in the male part 2, and a base portion having a narrow width w is formed as shown in FIG. By cutting, the male part 2 can be formed, and the male part 2 can be formed with a small cutting allowance. Similarly, the female real part 3 can also be formed with a small cutting allowance. Therefore, the floor material of the present invention has a smaller shaving allowance for the male part 2 and the male part 2 than the floor material 51 shown in FIG. 8 which requires a machining allowance with a width W to form the male part. Can be formed, and the yield of the substrate can be improved.

  Furthermore, in the flooring of the present invention, the upper ridge 10 of the female part 3 is inclined downward in the male part 2 even if the flooring 1 that is a wooden base material swells during the rainy season when the humidity is high. Since it is in a state of being sandwiched between the surface 6 and the upper surface of the male fruit 4, there is no step between the flooring 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 designs can be made without departing from the spirit of the present invention described in the claims. It can be changed. In the above embodiment, the upper inclined surface 5 of the male part 2 and the upward inclined surface 12 of the female part 3 are formed as flat surfaces. However, as shown in FIG. 5a is a curved surface having a substantially round shape in cross section, the upward inclined surface 12 of the female real part 3 is a curved surface having a substantially round shape in cross section, and the upper portion 12a that functions as the decorative groove 18 is a lower portion 12b below the curved portion. May be configured as a plane. Further, as shown in FIG. 5, when the upward inclined surface 12 is formed so that the portion 12c functioning as the decorative groove 18 is a flat surface, the lower portion 12d is formed into a curved surface having a substantially rounded cross section. The edge part of the upward inclined surface 12 can be made into a surface nearer horizontal. Further, as shown in FIG. 6, the upward inclined surface 12 of the female real part 3 is formed by an upper plane 12e that functions as a decorative groove 18 and a lower plane 12g that is lower than the upper plane 12e. If the plane 12g is configured to be continuous through the curved surface 12f having a substantially rounded cross section so that the plane 12g is inclined more horizontally than the upper plane 12e, no corners are formed between the planes 12e and 12g, so there is no sense of incongruity. In addition, even when the plate material contracts, the gap can be further reduced, and dust or the like accumulated in the gap can be further prevented from falling down.

  Furthermore, in the above-described embodiment, the floor material has been described. However, a plate member such as a ceiling plate or a wall member may be used as long as a male part and a female part are formed at both end portions and are actually joined. Of course it is good. 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.
