Interior surface materials for buildings

Abstract

Since the processing time is shorter than conventional methods and the required joint width can be secured before processing, this provides interior surface materials that can be formed quickly and accurately on the surface of interior structures. [Solution] The interior surface material is an interior surface material such as a decorative board or decorative panel formed on the surface of an interior structure such as the ceiling or wall of a building, and is bonded to a substrate 1. The substrate 1 has joint regions 3 that protrude from the interior surface material 1 along at least one of its four sides. The joint regions 3 serve as joints 3 between adjacent interior surface materials 1 when multiple interior surface materials 1 are attached to the interior structure.

Description

Technical Field

[0006] ,

[0001] The present invention relates to an interior finishing material provided inside a building and having a joint area on a substrate.

Background Art

[0002] Conventionally, buildings such as public buildings, houses, kindergartens, and nurseries have been renovated internally as needed to extend the life of the buildings. By renovation, the surfaces such as the ceiling, wall surfaces, and floor surfaces inside the building can be replaced with new finishing materials to create a different environment from before.

[0003] The applicant has previously filed an invention related to an interior construction method using a magnet sheet that can be easily constructed in a short time (see Patent Document 1). This is a method of preparing an interior sheet composed of a synthetic resin sheet and a magnet sheet and a base sheet composed of a magnetic material, determining an area for interior construction of a predetermined area on the floor surface or wall surface inside a building, and attaching the interior sheet to the base sheet formed on the surface of the area to be interior-constructed by magnetic force.

Summary of the Invention

Problems to be Solved by the Invention

[0005] When constructing a conventional building or renovating it, a plurality of interior finishing materials are laid on the interior structure such as the ceiling and walls. At that time, joints are made in the adjacent interior finishing materials as needed, or the two are brought into close contact.

[0006] Figure 5 illustrates a conventional method for forming a joint between two materials. In this conventional method of attaching interior surface materials such as decorative boards and decorative panels to interior structures such as ceilings and walls, a joint tape 30 is applied before attaching a pair of interior surface materials 10, 10 to the interior structure. Then, the two materials are placed facing each other on the joint tape 30 so that a portion of one side of each material overlaps the joint tape 30, and a joint is formed between them. These conventional methods required a large amount of material, were time-consuming to process, and tended to lack precision.

[0007] This invention was made under these circumstances, and provides an interior surface material that can be quickly and accurately formed on the surface of the interior structure of a building, by shortening the processing time compared to conventional methods and by ensuring the required joint width before processing. [Means for solving the problem]

[0008] One embodiment of the present invention relates to an interior surface material for buildings, which is an interior surface material such as a decorative board or decorative panel formed on the surface of an interior structure such as a ceiling or wall of a building, wherein the interior surface material is adhered to a substrate, and the substrate has a joint region that protrudes from the interior surface material along at least one of its four sides, and the joint region serves as a joint between adjacent interior surface materials when multiple interior surface materials are attached to the interior structure. [Effects of the Invention]

[0009] Because the substrate has joint areas, the processing time is shorter than in conventional methods, and the required joint width can be secured without error before processing. Therefore, interior surface materials can be formed quickly and accurately on the surface of the interior structure of a building. [Brief explanation of the drawing]

[Figure 2]Figure 1 is a cross-sectional view of the interior surface material, Figure 2A is a cross-sectional view of part AA in Figure 3, and Figure 2B is a cross-sectional view of part BB in Figure 3. [Figure 3] This is a plan view of the interior surface material according to Example 1, showing the surface that is joined to the substrate. [Figure 4] This is a plan view of the substrate according to Example 1, showing the surface that is joined to the interior surface material. [Figure 5] This is a plan view of a conventional interior surface material attached to an interior structure. [Modes for carrying out the invention]

[0011] Embodiments of the invention will be described below with reference to examples. [Examples]

[0012] As shown in Figures 1 to 4, the interior surface material in this embodiment is an interior surface material such as a decorative board or decorative panel formed on the surface of an interior structure such as the ceiling or wall of a building, and is bonded to a substrate 1. The substrate 1 has joint regions 3 that protrude from the interior surface material 1 along at least one of its four sides. These joint regions 3 serve as joints 3 between adjacent interior surface materials 1 when multiple interior surface materials 1 are attached to the interior structure.

[0013] As shown in Figure 1, the interior surface material in this embodiment has a structure in which multiple interior surface materials 1 are attached to interior structures such as ceilings and walls. The interior surface material 1 is formed on a substrate 2, and the area of ​​the substrate 2 that protrudes from the interior surface material 1 is a joint 3. In this embodiment, joints 3 are formed on all adjacent interior surface materials 1. As shown in Figure 2, the surface of the substrate 2 is covered with an interior surface material 1 such as a decorative board or decorative panel, and the interior surface material 1 is bonded to the surface of the substrate 2 using double-sided tape 4 (Figure 2A) and adhesive 5 (Figure 2B). The interior surface material 1 and the substrate 2 are joined together by double-sided tape 4 and adhesive 5, and sound-absorbing material 6 is inserted in the areas where these joining materials are not applied to improve the insulation and airtightness of the room (Figure 2A).

[0014] As shown in FIGS. 2B and 3, the double-sided tape 4 and the adhesive 5 are configured to be composed of a plurality of linear bodies arranged at intervals. This facilitates the access to the areas where the bonding material of the sound-absorbing material (FIG. 2A) is not applied. FIG. 3 shows an interior finish surface material 1 such as a surface decorative panel, representing the surface adhered to the substrate 2. FIG. 2A shows a cross-sectional view of the A-A portion shown in FIG. 3, and FIG. 2B shows a cross-sectional view of the B-B portion shown in FIG. 3.

[0015] Referring to FIGS. 2A and 3, the cross-sectional view of the A-A portion of FIG. 3 will be described. The substrate 2 and the interior finish surface material 1 (aluminum composite panel in the embodiment) are joined by the double-sided tape 4 that constitutes the linear body. The thickness of the double-sided tape 4 needs to be thicker than the thickness of the sound-absorbing material 6 so that the sound-absorbing material 6 can be inserted into the space surrounded by a pair of the linear bodies adjacent to the substrate 2 and the interior finish surface material 1. And the sound-absorbing material 6 is inserted into the space surrounded by a pair of the linear bodies adjacent to the substrate 2 and the interior finish surface material 1.

[0016] Next, referring to FIGS. 2B and 3, the cross-sectional view of the B-B portion of FIG. 3 will be described. FIG. 2B shows a cross-sectional view of the B-B portion shown in FIG. 3. The substrate 2 and the interior finish surface material 1 are joined by the linear bodies composed of the double-sided tape 4 and the adhesive 5. No sound-absorbing material exists in this portion in FIG. 2B. The thicknesses of the double-sided tape 5 and the adhesive 6 (about 0.1 to 10 mm) are at least thicker than the sound-absorbing material 6.

[0017] FIG. 4 is a plan view of the surface of the substrate 2 where the interior finish surface material 1 is bonded. The sides where the joint area 3 is formed are two sides, but one side or more may also be acceptable.
