Description

[Technical field]

[0001] The present invention relates to construction materials. [Background technology]

[0002] In buildings such as houses, a frame is installed at a part where there is a step. A frame is a decorative material installed at the end of the higher part of the step. For example, in an entrance hall, there is a step between the floor of the entrance hall (hereinafter referred to as the "entrance floor") and the floor of the corridor (hereinafter referred to as the "floor"). A fitting material called an entrance frame is attached to the higher end of the part where there is a step. Also, in a staircase, there is a step between the floor of the upper floor and the step board one step below. A fitting material called an upper step frame is attached to the higher end of the part where there is a step. Some frames have a base material made of laminated wood with a decorative material attached to the front and top. This base material is highly water absorbent, and the moisture absorbed by the base material can cause mold to grow on the decorative material, causing discoloration and rotting. In particular, during construction, mortar is applied to the entrance floor, and the entrance frame is installed on the mortar. In such cases, the base material of the entrance frame absorbs moisture from the mortar, causing mold and mildew to grow on the decorative material, resulting in problems with the design of the entrance frame.

[0003] Patent Document 1 discloses a flooring material that is ideal for entrance frames. The flooring material described in Patent Document 1 has a waterproof layer formed on the back side of the wooden base material. This prevents the base material from absorbing moisture from under the floor, making the base material less susceptible to rotting and preventing discoloration due to mold growth.

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 63-187664 Summary of the Invention [Problem to be solved by the invention]

[0005] In the limited space of an entrance hall where guests are invited in, it is desirable to improve the appearance. For this reason, if a waterproof layer is provided on the back surface (bottom surface) opposite to the top surface, as in the flooring material described in Patent Document 1, the exposed waterproof layer may be visible and may impair the design of the entrance hall. In particular, the back surface of the upper step frame is easily visible to people coming up from the floor below.

[0006] In addition, the flooring material described in Patent Document 1 has a moisture-proof layer on the rear surface, which is not in direct contact with the mortar containing water. However, although there is almost no effect of preventing moisture on the rear surface, the cost increases due to the increase in processing steps and materials, resulting in a low cost-effectiveness. Furthermore, by treating the rear surface, there is a risk of the front decorative surface being scratched during the manufacturing process. In addition, Patent Document 1 specifically exemplifies a waterproof layer formed by applying a urethane resin paint, but such a waterproof layer has a low moisture-proof effect, and there is a problem that the moisture-proof performance varies depending on the coating thickness or coating unevenness during manufacturing. Furthermore, since the paint turns yellow due to ultraviolet rays or aging, there is a concern that the design will deteriorate over time, and there is also a problem that the moisture-proof performance may deteriorate if the coating cracks.

[0007] Therefore, one example of an object of the present invention is to provide a construction material for use in frame members that makes the base material less susceptible to decay and prevents discoloration due to mold growth without impairing the design. [Means for solving the problem]

[0008] In order to achieve the above object, a construction material according to one aspect of the present invention comprises: A construction material used for a frame, A wood base material, A top surface decorative material provided on a top surface of the wood base material; A front decorative material provided on the front surface of the wood base material; A moisture-proof sheet provided on the bottom surface of the wood base material; A wood sheet provided on the surface of the moisture-proof sheet; Equipped with The moisture-proof sheet covers the bottom surface of the front decorative material. It is characterized by: Effect of the Invention

[0009] According to the present invention, it is possible to realize a construction material for use in frame members that has a base material that is resistant to decay and that is prevented from discoloration due to mold growth, without compromising the design. [Brief description of the drawings]

[0010] [Figure 1] FIG. 1 shows the state after construction materials have been installed. [Diagram 2] FIG. 2 is a diagram showing a construction material according to the embodiment. [Diagram 3] FIG. 3 is a diagram showing a moisture-proof sheet having a chamfered portion. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] The joinery material of the present embodiment is used, for example, as a frame, more specifically, as a step frame for an entrance or a step frame for an upper staircase, etc. In the following, the joinery material will be described as being used for a step frame for an entrance.

[0013] FIG. 1 is a diagram showing the state in which construction material 1 has been installed.

[0014] The fitting material 1 is installed in a corner portion going up from the entrance 100 to the floor 101 inside the room. The entrance 100 is constructed with a finishing material such as tiles or cement. In the portion going up from the entrance 100 to the floor 101, a base 103 is constructed on a foundation 102. A floor joist 104 is provided on the base 103, and a floor base 105 and a floor decorative material 106 are constructed on the floor joist 104.

[0015] The fitting material 1 is installed in the corner portion. A wooden base 107 is provided on the foundation 102. Mortar 108 is provided on the front side (the entrance 100 side) of the foundation 102. The fitting material 1 is placed on the wooden base 107 and mortar 108, and is fixed to the wooden base 107 and base 103 with a urethane adhesive.

[0016] The construction material 1 of this embodiment is configured to be able to suppress the occurrence of mold and discoloration caused by absorbing moisture from the mortar 108 when installed as shown in FIG.

[0017] Fig. 2 is a diagram showing the fixture of this embodiment, in which a part of the fixture 1 is shown in an enlarged manner.

[0018] The construction material 1 includes a wooden base material 10. The wooden base material 10 is columnar. The wooden base material 10 may be made of, for example, solid wood, laminated lumber, plywood, LVL (Laminated Veneer Lumber), wood fiberboard such as MDF (Medium Density Fiberboard) or HDF (High Density Fiberboard), or may be made of particle board, OSB (Oriented Strand Board), or a laminate of these.

[0019] In the following description, the surface of the wooden base material 10 that is the top surface when the fitting material 1 is constructed and that will become part of the floor 101 is referred to as the top surface. The surface opposite the top surface and that will be on the mortar 108 and foundation 102 side when the fitting material 1 is constructed is referred to as the bottom surface. Furthermore, the surface of the wooden base material 10 that is adjacent to the top surface and bottom surface, faces the entrance 100 side when the fitting material 1 is constructed, and is approximately perpendicular to the floor part of the entrance 100 is referred to as the front surface.

[0020] A top surface decorative material 11 is provided on the top surface of the wooden base material 10. The top surface decorative material 11 forms part of the floor 101 when the fitting 1 is installed. The top surface decorative material 11 has a thickness of, for example, about 0.1 mm to 5.0 mm. The material of the top surface decorative material 11 is not particularly limited, but it may be formed, for example, from wood decorative material such as veneer or sawn board, a resin sheet such as an olefin sheet or a polyvinyl chloride sheet, or a paper sheet with a printed pattern.

[0021] A front decorative material 12 is attached to the front surface of the wooden substrate 10. The front decorative material 12 has a thickness of, for example, about 0.1 mm to 5.0 mm. The material of the front decorative material 12 is not particularly limited, but may be, for example, a wood decorative material such as veneer or sawn board, a resin sheet such as an olefin sheet or polyvinyl chloride sheet, or a paper sheet with a printed pattern. As shown in the enlarged portion of FIG. 2, the end face of the front decorative material 12 on the bottom side of the wooden substrate 10 is approximately flush with the bottom surface of the wooden substrate 10.

[0022] A moisture-proof sheet 13 is attached to the bottom surface of the wooden base material 10. The bottom surface of the wooden base material 10 and the end surface of the front decorative material 12, which is the bottom side of the bottom surface, are flush with each other. The moisture-proof sheet 13 is attached so as to cover the flush bottom surface of the wooden base material 10 and the end surface of the front decorative material 12. As will be described later, the moisture-proof sheet 13 is a member that prevents the wooden base material 10 and the front decorative material 12 from absorbing moisture from the mortar 108 when the fitting material 1 is placed on the mortar 108. For this reason, the moisture-proof sheet 13 is formed from a material that is moisture-proof and water-resistant. The moisture-proof and water-resistant performance of the moisture-proof sheet 13 is such that the moisture permeability measured in accordance with JIS Z0208 is 30 g / (m 2 ·24h) or less, preferably 20g / (m 2 24h) or less, more preferably 10g / (m 2 The lower the moisture permeability, the greater the effect of preventing discoloration, decay, or mold growth due to moisture transfer.

[0023] Examples of the moisture-proof sheet 13 include polyethylene resin, polypropylene resin, polyethylene terephthalate resin, polystyrene resin, polyvinyl chloride resin, and acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS resin) molded into a sheet or plate shape. The moisture-proof sheet 13 may be a laminate of a plurality of these resins integrated together, or may be a metal layer (a metal made into a sheet shape) such as aluminum foil. Furthermore, it may be a laminated paper made by laminating a resin and paper, or a polysand paper. From the viewpoint of moisture prevention, it is not limited to a sheet-like material, and it is also possible to apply a resin paint, but there is a problem that the moisture-proof effect of the resin paint is low and the moisture-proof performance varies depending on the coating thickness or coating unevenness during manufacturing. Furthermore, since the paint turns yellow due to ultraviolet rays or aging, there is a concern that the design will deteriorate over time, and there is also a problem that the moisture-proof performance may deteriorate if the coating cracks occur.

[0024] The thickness of the moisture-proof sheet 13 is about 0.1 mm to 1.0 mm, more preferably 0.1 mm to 0.5 mm, and further preferably 0.1 mm to 0.3 mm. There are no particular limitations on the method for adhering the moisture-proof sheet 13, and for example, a water-based adhesive, a resin-based adhesive, a hot melt adhesive, or a pressure sensitive adhesive may be used.

[0025] A wooden sheet 14 is attached to the surface of the moisture-proof sheet 13. The material of the wooden sheet 14 is not particularly limited as long as strength and durability are ensured, and examples of the material include veneer, single board, sawn board, and fiberboard such as MDF and HDF. The thickness of the wooden sheet 14 is not particularly limited, but is preferably thin in consideration of material costs and workability during production. The thickness of the wooden sheet 14 is 0.1 mm to 5.0 mm, more preferably 0.1 mm to 3.0 mm, and even more preferably 0.1 mm to 1.0 mm. The method of adhering the wooden sheet 14 is not particularly limited, and examples thereof include water-based adhesives, resin-based adhesives, hot melt adhesives, and pressure sensitive adhesives.

[0026] When the fitting material 1 with the moisture-proof sheet 13 and wooden sheet 14 attached is placed on the mortar 108, the moisture in the mortar 108 is absorbed by the wooden sheet 14. However, because the moisture-proof sheet 13 covers the bottom surface of the wooden base material 10, the moisture in the mortar 108 is prevented from penetrating into the wooden base material 10. This prevents the occurrence of mold and the like in the front decorative material 12 due to moisture penetrating from the wooden base material 10 into the front decorative material 12.

[0027] In addition, since the moisture-proof sheet 13 covers the end face of the front decorative material 12, even if the front decorative material 12 is installed so that it is located directly above the mortar 108, the moisture of the mortar 108 is prevented from penetrating directly into the front decorative material 12. In addition, there are cases where the mortar 108 is installed after the fitting material 1 is installed. In this case, the mortar 108 is often installed up to just below the front decorative material 12, and the mortar 108 contains more moisture than when the fitting material 1 is placed and installed after the mortar 108 has been installed and dried to a certain extent. For this reason, the moisture-proof sheet 13 covering the end face of the front decorative material 12 is particularly effective in preventing moisture from penetrating directly into the front decorative material. This prevents the occurrence of mold and the like on the front decorative material 12. In other words, the moisture-proof sheet 13 prevents the moisture in the mortar 108 from indirectly penetrating into the front decorative material 12 via the wood base material 10 and from directly penetrating into the front decorative material 12 .

[0028] Also, by providing the wood sheet 14 on the surface of the moisture-proof sheet 13, it is possible to prevent the design of the bottom side of the fitting material 1 from being impaired. Furthermore, the wood sheet 14 acts to suppress expansion and contraction of the moisture-proof sheet 13 due to temperature (especially heat during drying in the coloring and painting processes), so that it is possible to prevent the moisture-proof sheet 13 from peeling off from the wood base material 10.

[0029] In addition, a chamfered portion 14A is formed at the end of the wood sheet 14, which is inclined with respect to the bottom surface of the wood base material 10. By forming the chamfered portion 14A, burrs or fuzz generated during manufacturing can be removed, clothes and the like can be prevented from getting caught after the fitting material 1 is installed, and cracks in the wood sheet 14 caused by corner hitting during transportation of the fitting material can be prevented.

[0030] The chamfering to form the chamfered portion 14A may be C-surface processing (45°) formed only on a flat surface, chamfering at an angle other than 45°, R-surface processing including a curved surface, or chamfering of a shape combining a flat surface and a curved surface.

[0031] The chamfered portion 14A may be formed in advance on the wood sheet 14, or may be formed when the wood sheet 14 is attached to the surface of the moisture-proof sheet 13. As shown in FIG. 3, the moisture-proof sheet 13 may also have a chamfered portion 14A formed thereon. FIG. 3 shows the moisture-proof sheet 13 having the chamfered portion 14A formed thereon. In this case, the chamfered portion 14A is formed at the ends of the wood sheet 14 and the moisture-proof sheet 13 such that the moisture-proof sheet 13 remains on the end face of the front decorative material 12. Therefore, even when the chamfered portion 14A is formed on the moisture-proof sheet 13, it is possible to prevent moisture from the mortar 108 from directly penetrating into the front decorative material 12.

[0032] Next, a manufacturing method of the fitting 1 will be described.

[0033] First, the front decorative material 12 is attached to the front surface of the wooden base material 10. The end face of the front decorative material 12 on the bottom side of the wooden base material 10 is made approximately flush with the bottom surface of the wooden base material 10. Then, the attached front decorative material 12 is deburred.

[0034] Next, the moisture-proof sheet 13 is attached to the bottom surface of the wooden substrate 10. There are no particular limitations on the method for attaching the moisture-proof sheet 13, but for example, a water-based adhesive, a resin-based adhesive, a hot melt adhesive, or a pressure-sensitive adhesive may be used to attach the wood substrate 10 and the moisture-proof sheet 13. At this time, the moisture-proof sheet 13 is attached so as to cover the bottom surface of the wood substrate 10 and the end surface of the front decorative material 12 that is flush with the bottom surface. Thereafter, burrs are removed from the moisture-proof sheet 13.

[0035] Next, the wooden sheet 14 is attached to the surface of the moisture-proof sheet 13. There is no particular limitation on the method for adhering the wooden sheet 14, but for example, a water-based adhesive, a resin-based adhesive, a hot melt adhesive, or a pressure-sensitive adhesive is used to adhere the wooden sheet 14 and the moisture-proof sheet 13. Then, the wooden sheet 14 is chamfered. The chamfering may be performed using a blade or sandpaper. The moisture-proof sheet 13 and the wooden sheet 14 may be integrated in advance.

[0036] A top surface decorative material 11 is attached to the top surface of the wooden base material 10. Then, burrs are removed from the attached top surface decorative material 11. The top surface decorative material 11 is also chamfered. After that, the fitting material 1 is colored and dried, and then painted and dried. [Explanation of symbols]
