Description

  The present invention can neatly construct the finish of the left and right baseboards extending along the lower edge of the wall toward the entrance corner or the exit corner of the wall without requiring skill. It relates to the structure of the baseboard connection.

  As shown in FIG. 5, the left and right baseboards b and b at the corners of the wall are cut off at 45 ° diagonally from the left and right baseboards by matching on the site, We are constructing by matching. However, a gap and a level difference d are likely to occur in the abutting portion, and considerable skill is required in order to keep them cleanly. Further, due to warpage of the baseboard member, the end fixing of one baseboard may be loosened and the appearance may be impaired.

  Therefore, as shown in FIG. 6, the present applicant covers the connecting portions of the baseboards b and b by covering the baseboards b and b with the baseboard cap a formed in an L shape from the left and right baseboards b and b. The structure which prevented the clearance gap and the level | step difference d by this, and improved workability is proposed. The baseboard cap a has a thin plate shape that follows the surface shape of the baseboard b, and is formed using plastic, metal, etc., and the engaging piece formed on the back surface is engaged with the baseboard b. It is fixed to the surface of the baseboard b using an adhesive (see, for example, Patent Document 1).

  However, even though it is formed in a thin plate shape, the linear step formed at the end of the baseboard cap a is conspicuous, and the baseboard cap a can be formed in the same appearance as the baseboard b, such as a pattern and color tone. Are different from each other. Also, due to the warp of the baseboard member, its mounting position error, subtle irregularities on the wall surface, etc., it is easy to cause a deviation in the height or the entry / exit direction between the finished surfaces of the left and right baseboards b, b. In this case, there is a problem that a subtle inclination is generated in the baseboard cap a to be put thereon or a gap is formed at an end portion of the baseboard cap a when the shift cannot be absorbed.

  In addition, when the baseboard cap a is mounted by the one-touch method using the locking piece, although it is excellent in workability, if the baseboard cap a is deformed due to a difference in thermal expansion, aging, etc., due to traffic vibration, walking, etc. The baseboard cap a is easily disengaged.

  The present invention is based on attaching a baseboard joint by continuously fitting the slits of the left and right baseboard bodies and the baseboard joint slit to the horizontal piece of the fixture, and for the appearance of the finish. It is an issue to provide a structure of a baseboard connecting portion that is excellent and has good workability.

In the invention according to claim 3, the ratio between the thickness Wa of the base of the horizontal piece and the opening dimension Wb of the slits of the baseboard body and baseboard joint material (Wa / Wb) is 1.05 or more and less than 1.5, and the baseboard body and the baseboard joint material according to claim 4 are formed with a recess capable of accommodating the substrate of the fixture on the lower side of the back surface. It is characterized by being.

  In the invention according to claim 1, since the slits of the same height are fitted to the horizontal pieces that are continuous laterally, the mounting heights of the left and right baseboard bodies and the baseboard joint material are uniform, and the appearance is good. Excellent. Further, the left and right baseboard bodies and the baseboard joint material are firmly fixed by fitting the horizontal piece of the fixture to the slits on the back surface, and the attachment strength is further stabilized by the combined use with an adhesive. Moreover, the baseboard body and the baseboard joint material can be aligned and attached simply by fitting the slit to the horizontal piece of the fixture, so that it is excellent in workability and does not require skill in the work.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the structure 1 of the baseboard connecting portion is employed at the entrance corner or the exit corner where the left and right walls K, K intersect, and the lower ends of the left and right walls K, K The left and right baseboard bodies 2 and 2 attached along the left and right baseboards, the baseboard joint material 3 arranged at the connecting portion of the left and right baseboard bodies 2 and 2, and the fixture 4 for fixing the baseboard joint material 3 And comprising.

  As shown in FIG. 2, the fixture 4 is bent at a right angle to the outside and has a horizontal section L-shaped, and is projected to the front at a small length approximately in the middle of the board 7, and continues horizontally. It consists of pieces 6. As shown in FIG. 3 (A), the horizontal piece 6 of this embodiment is formed in a tapered shape with a thickness that gradually decreases from the base portion toward the tip and with a sharp tip. In this embodiment, the substrate 7 and the horizontal piece 6 are integrally formed using a plastic such as polyethylene, polypropylene, polystyrene, or polyethylene terephthalate, but a metal such as iron or aluminum can also be used.

  As shown in FIG. 2, the fixture 4 is attached along the projecting corner portion of the wall K without any gap by a fixing tool 22 such as a nail or a screw inserted into a mounting hole 21 drilled in the substrate 7. When an adhesive is used in addition to the fixing tool 22, the mounting strength is further stabilized. When the wall K bends at an obtuse angle exceeding a right angle or forms an acute angled corner of less than 90 degrees, the substrate 7 of the fixture 4 is formed in a shape that matches the angle of the angled corner. The

  As shown in FIGS. 2 and 3, the baseboard body 2 has a horizontally long strip shape covering between the wall K and the floor F. In this embodiment, the height of the upper surface is about one third. A decorative groove 23 extending in a straight line is provided. Further, as shown in FIG. 3, the lower surface of the back surface has a recess 8 formed by a small step Tb. The recess 8 is formed such that the small step Tb is the same as or slightly larger than the thickness Ta of the substrate 7 of the fixture 4. Therefore, when the baseboard body 2 is attached to the fixture 4 in an overlapping manner, the substrate 7 is accommodated in the recess 8 and a gap can be prevented from being generated between the baseboard body 2 and the wall K.

  As shown in FIG. 2, the base material 3 is formed by extending arm portions 3 </ b> A and 3 </ b> A having the same vertical cross section as the base body 2 in a perpendicular direction from a vertical ridge line portion G in a small length. The cross section is L-shaped. The left and right baseboard bodies 2, 2 are arranged between the left and right baseboard bodies 2, 2. Accordingly, the baseboard joint 3 is also formed with a decorative groove 23 continuous with the baseboard body 2 and a recess 8 for receiving the substrate 7 of the fixture 4. Similarly to the substrate 7 of the fixture 4, when the protruding corner of the wall K bends at an angle other than a right angle, it is formed at an angle that matches this.

  The baseboard joint material 3 and the baseboard body 2 are attached to the horizontal piece 6 of the fixture 4 to attach the baseboard joint material 3 and the baseboard body 2, so that the baseboard joint material 3 and the baseboard body 2 are horizontally attached to the back surface of the fixture 4. A slit 5 having the same height as the piece 6 is provided. The slit 5 of this embodiment is formed by horizontally cutting the back surface in the recess 8. In addition, about the baseboard main body 2, you may provide the slit 5 only in the edge part which continues to the baseboard joint material 3. FIG.

  In the present embodiment, the slits 5 are formed in a uniform width from the opening edge to the back as shown in FIG. 3A, but may be formed in a tapered shape. Moreover, the opening dimension (slit width dimension) of the slit 5 is formed uniformly. And if this opening dimension is set to Wb, thickness Wa of the horizontal piece 6 base part of the fixture 4 of this form is formed in the ratio (Wa / Wb) with Wb being 1.05 or more and less than 1.5. . If it is less than 1.05, the support strength of the horizontal piece 6 fitted in the slit 5 may be insufficient, and there is a possibility of falling off. Conversely, if it exceeds 1.5, a large force is required for the fitting. In addition, there is a possibility that a crack is generated from the back of the slit 5 due to the wedge effect, and a crack is generated on the surface of the baseboard joint material 3 or the baseboard body 2.

  The height Hb of the baseboard joint material 3 and the baseboard body 2 is, for example, about 50 to 150 mm, preferably 65 to 100 mm, and 72 mm in this embodiment. If the height of the substrate 7 of the fixture 4 is Ha, the height ratio (Ha / Hb) to the baseboard body 2 is, for example, about 0.5 to 0.95, and 0.91 in this embodiment. Yes. Further, the base material 3 has an extension length L from the back surface of the other arm portion 3A of the one arm portion 3A, for example, about 2 to 20 mm, preferably 4 to 10 mm, and in this embodiment, 5.5 mm. It is said. If it is less than 2 mm, the fitting length between the slit 5 and the horizontal piece 6 of the fixture 4 is insufficient, so that the support force of the baseboard joint material 3 becomes unstable. Conversely, if it exceeds 20 mm, the baseboard joint material 3 Since the size as a member increases, the handleability decreases.

  In addition, the baseboard body 2 and the baseboard joint material 3 of this embodiment are made of a base 24 formed by cutting a plywood into a predetermined shape and an olefin resin such as polyethylene, polypropylene, ethylene vinyl acetate resin (EVA), or a melamine resin. It is formed by sticking a polyester resin or other resin sheet 25. Alternatively, the base 24 using a woody material such as MDF (medium density fiberboard), particle board, and laminated wood can be coated with decorative paper, and an unsaturated polyester resin can be applied on the base 24. The surface 24 may be formed by directly coating a polyester paint, polyurethane paint, aminoalkyd paint, acrylic paint, or the like.

  The baseboard body 2 and the baseboard joint material 3 formed in this way are fixed to the lower end of the protruding corner of the wall K by continuously fitting both slits 5 to the horizontal piece 6 of the fixture 4. Is done. Since both slits 5 formed at the same height are fitted into a horizontally continuous horizontal piece 6, the baseboard body 2 and the baseboard joint material 3 have a uniform height and a stepped surface. The finish with good appearance is obtained continuously. And since it can align correctly by the simple operation | work which fits the slit 5 to the horizontal piece 6 as mentioned above, it is excellent in workability | operativity and does not require skill.

  Further, the left and right baseboard bodies 2 and 2 and the baseboard joint material 3 are securely fixed by fitting the slits 5 provided on the back surface to the horizontal pieces 6 of the fixture 4. Therefore, for example, even if the baseboard body 2 generates a little fray due to aging, it is possible to prevent the fixing from being released. In addition to this, it is also possible to fix the baseboard body 2 and the baseboard joint material 3 and the fixture 4 with an adhesive, which is preferable in that the fixing reliability is further improved.

  FIG. 4 illustrates another embodiment. Hereinafter, different contents will be described, and other than that, only the same reference numerals are given to the main components shown in the figure. As shown in FIG. 1, this embodiment is employed in a corner where the left and right walls K intersect. The fixture 4 according to this embodiment includes a substrate 7 that is bent inward at a right angle and has an L-shaped horizontal section, and a horizontal piece 6 that protrudes inward at a small length approximately in the middle of the substrate 7 and that continues horizontally. . The fixture 4 is attached without a gap along the corner of the wall K by a fixing tool 22 such as a nail or a screw inserted into the mounting hole 21 of the substrate 7. Further, the baseboard joint material 3 of the present embodiment is formed by extending arm portions 3A and 3A having the same vertical cross section as the baseboard body 2 in a direction perpendicular to the vertical valley line portion V in a small length and having a small length. It is L-shaped.

  The left and right baseboard bodies 2 and 2 and the baseboard joint material 3 of this embodiment are securely fixed to the lower end portion of the wall K by fitting the slits 5 provided on the back surface to the horizontal pieces 6 of the fixture 4. The In the conventional construction method in which the baseboard main body 2 is cut obliquely, it is difficult to perform on-site alignment particularly at the corners, and the gaps and gaps tend to occur. However, in the structure 1 of the baseboard connection part, since it can be attached to a simple and accurate position by a standardized operation like the above-mentioned corner part, the workability is very good.
