Description

Technical Field

[0001] The present invention relates to a decorative material.

Background Art

[0002] There is a material called a mesh member as an interior material that is attached to a flat construction surface such as a wall or ceiling of a building. This mesh member is formed by braiding strip members obtained by processing plants into long and thin shapes, and is likely to come apart during attachment. For this reason, conventionally, as shown in Patent Document 1, a construction method has been adopted in which it is previously adhered to a flat plywood and the plywood is attached.

[0003] However, due to the revision of the building standards, high seismic resistance has been required for buildings. Therefore, in the case of using plywood like the decorative material described in Patent Document 1, the weight of walls and ceilings increases, and the seismic resistance deteriorates. As a result, there is a problem that the rigidity of the support structure for walls and ceilings has to be improved, increasing the construction cost.

[0004] In addition, in recent years, many buildings have high design quality, and those using curved walls and ceilings have also increased. However, since the mesh member of the decorative material described in Patent Document 1 is attached to the plywood, there is a problem that it will be damaged if it is forcibly bent according to the curved construction surface.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Therefore, the main object of the present invention is to obtain a decorative material using a mesh member that is lightweight and difficult to be damaged even when attached to a curved construction surface. [Means for solving the problem]

[0007] The decorative material according to the present invention comprises a woven basketry member formed by braiding strip members created by processing plants into elongated strips, and a flexible sheet member adhered to the back surface of the woven basketry member, wherein the woven basketry member has portions where the strip members overlap, and the strip members constituting the overlapping portions are not adhered to each other.

[0008] With this configuration, since the woven bamboo members are bonded to the sheet members, it is lighter than decorative materials that are bonded to plywood, as described in Patent Document 1, and is less likely to adversely affect the seismic resistance of the building. Furthermore, since the sheet members are flexible and the band members that make up the overlapping parts of the band members are not bonded to each other, gaps are formed in the overlapping parts of the band members. These gaps provide play, making it easier to bend, and even when bent, it is less likely to break or crack.

[0009] Furthermore, the decorative material according to the present invention comprises a woven basketry member formed by braiding strip members created by processing plants into elongated strips, and a flexible sheet member adhered to the back surface of the woven basketry member, wherein the woven basketry member has portions in which the strip members overlap each other, and the strip members constituting the overlapping portions are adhered to each other, and the adhesion between the strip members can be peeled off when the woven basketry member and the sheet member are bent.

[0010] With this configuration, since the woven bamboo members are bonded to the sheet member, it is lighter than decorative materials where the woven bamboo members are bonded to plywood, as described in Patent Document 1, and is less likely to adversely affect the seismic resistance of the building. Also, since the band members that make up the overlapping parts of the band members are bonded to each other, it is possible to prevent damage caused by objects getting caught in the overlapping parts of the band members during transportation, for example. Furthermore, as in the conventional method, when attached to a flat surface, the adhesion of the overlapping parts of the band members is maintained, preventing damage caused by objects getting caught in the overlapping parts of the band members. Moreover, by bending, the adhesion of the band members that make up the overlapping parts of the band members separates, creating a gap in the overlapping parts of the band members. This gap provides play, making it easier to bend, and also making it less likely for cracks or other damage to occur even when bent.

[0011] Furthermore, the portion where the strip members overlap comprises a back strip member and a front strip member, and the back strip member has its back surface adhered to the sheet member and its front surface adhered to the front strip member, and the adhesive force of the back strip member to the front strip member is configured to be weaker than the adhesive force to the sheet member.

[0012] With this configuration, when the material is bent, the strip member on the back will separate from the strip member on the front before the sheet member. This allows for the formation of gaps in the overlapping parts of the strip members while maintaining adhesion between the woven bamboo member and the sheet member.

[0013] Furthermore, the band member on the back side may be such that only its edges are adhered to the band member on the front side.

[0014] With this configuration, for example, a sheet material coated with adhesive can be easily formed by simply pressing it into a mesh material.

[0015] Furthermore, the sheet member may be made primarily from inorganic fibers.

[0016] With such a configuration, although the mesh member is made of a material that is prone to combustion, the sheet member is made of a material that is difficult to burn. Therefore, when considering the entire decorative material, it is easier to meet the fire resistance performance defined in the Building Standards Law. Also, since the sheet member is difficult to break, the durability is increased. Furthermore, since the sheet member can be formed thinner than plywood, the weight can be reduced.

Advantages of the Invention

[0017] Thus, with the decorative material according to the present invention, despite using a mesh member, it is lightweight and difficult to be damaged even when attached to a curved construction surface.

[Figure 3] It is a cross-sectional view schematically showing the decorative material of the second embodiment.

Modes for Carrying Out the Invention

[0019] The decorative material according to the present invention is mainly used as an interior material for buildings. Specifically, it is used by being attached to walls, ceilings, etc. of buildings.

[0020] <First Embodiment> The decorative material 100 according to this embodiment is in the form of a flexible sheet. As shown in FIG. 1, it includes a mesh member 10 and a sheet member 20 adhered to the back surface of the mesh member 10. The mesh member 10 and the sheet member 30 are adhered by an adhesive 30. Note that the decorative material 100 is attached such that the side of the mesh member 10 becomes the surface.

[0021] The net-like member 10 is formed by a plurality of strip members 11 formed by processing a plant into an elongated shape. Examples of the plant include those having flexibility, such as trees like cedar and cypress, and grasses like bamboo and reed. The strip member 11 of the present embodiment is in the form of a belt that is long and flat. The net-like member 10 is formed by braiding a plurality of strip members 11 in a predetermined pattern. Therefore, the net-like member 10 has a structure in which portions 10x where the strip members 11 overlap are regularly arranged. Specifically, the portion 10x where the strip members 11 overlap is a portion where separate (individual) strip members 11 overlap each other. Examples of the braiding pattern include patterns generally used in textiles such as diagonal weaving and basket weaving, but are not limited thereto. Since the net-like member 10 of the present embodiment is formed by plain weaving the strip members 11, the portions 10x where the strip members 11 overlap are arranged in a lattice pattern. More specifically, with respect to the stretching direction of the strip member 11, the portions 10x where the strip members 11 overlap and the portions 10y where the strip members 11 do not overlap are alternately arranged. That is, the portions 10y where the strip members 11 do not overlap are formed adjacent to the portions 10x where the strip members 11 overlap.

[0022] The sheet member 20 has flexibility. The sheet member 20 preferably has the same or a larger ultimate deflection amount than the strip member 11. Here, the ultimate deflection amount indicates the amount of deflection of a member formed in a predetermined shape by applying a load until it bends or just before it breaks. The deflection amount indicates, for example, the deflection amount measured based on a three-point bending test. More specifically, it indicates the deflection amount measured by adjusting the size of the test piece based on JIS K 7074. When a test piece of the same size as the sheet member 20 is deflected by a three-point bending test, the strip member 11 reaches the ultimate deflection amount earlier than the sheet member 20.

[0023] Furthermore, the sheet member 20 is preferably non-combustible. Specifically, it may be a sheet made of an inorganic material or a sheet made primarily of an inorganic material. More specifically, for example, as the sheet member 20, an inorganic fiber sheet (inorganic fiber paper) made primarily of inorganic fibers with a thickness of 0.15 mm to 3.00 mm may be used. The inorganic fiber sheet may be made only of inorganic fibers such as glass fibers or ceramic fibers, or it may be made primarily of these inorganic fibers and contain inorganic materials other than inorganic fibers (for example, stone powder such as magnesium silicate). The inorganic fiber sheet may also contain some organic material. Examples of sheet made of inorganic materials include aluminum foil.

[0024] The adhesive 30 is preferably non-flammable and elastic in a dry state. The adhesive may be organic or inorganic. In the case of an inorganic adhesive, for example, one that mainly uses silica or alumina may be used.

[0025] Next, while describing the manufacturing method of the decorative material 100 according to this embodiment, the adhesive structure between the woven bamboo member 10 and the sheet member 20 will be explained.

[0026] First, multiple strip members 11 are braided together on a flat surface to form a basket weave member 10. In this embodiment, multiple strip members 11 are plain woven to form the basket weave member 10. Next, adhesive 30 is applied to the sheet member 20. It is preferable to apply the adhesive 30 to one side of the sheet member 20 with a uniform thickness. Then, the sheet member 20 with the adhesive 30 applied is brought into close contact with the basket weave member 10 and bonded together to form the basket weave member 10.

[0027] As a result, as shown in Figure 2, when looking at the overlapping portion 10x of the strip members 11, the back surface (specifically, the entire back surface) of the back strip member 11a is adhered to the sheet member 20. On the other hand, the front surface of the back strip member 11a is not adhered to the front strip member 11b. In other words, in the overlapping portion 10x of the strip members 11, the strip members 11a and 11b that make up that portion are not adhered to each other.

[0028] Furthermore, when looking at the portion 10y where the strip members 11 do not overlap, the space between the strip member 11c and the sheet member 20 is filled with adhesive 30, and this adhesive 30 causes the back surface of the strip member 11c to be bonded to the sheet member 20. Also, via the adhesive 30, the strip member 11c is bonded to the strip member 11a on the back side. Incidentally, this bond can be peeled off by bending it to a certain extent.

[0029] With this configuration, the overlapping portions 10x of the strip members 11 are not adhered to each other, so a gap is formed in the overlapping portions 10x of the strip members 11. This gap provides play, making it easier to bend, and also making it less likely for cracks or other damage to occur when bent.

[0030] Furthermore, since a non-combustible material is used for the sheet member 20, the decorative material 100 as a whole is more likely to meet the fire resistance performance requirements stipulated by the Building Standards Act. In addition, by using an inorganic fiber sheet for the sheet member 20, while ensuring sufficient flexure, it becomes lighter than decorative materials that are bonded to plywood, such as those described in Patent Document 1, thus less likely to adversely affect the seismic resistance of the building and can be attached to curved surfaces.

[0031] Furthermore, since the back side of the overlapping portion 10x of the strip members 11 and the strip member 11c that constitutes the portion 10y where the strip members 11 do not overlap are bonded to each other, it is possible to prevent the front side strip member 11b from lifting away from the back side strip member 11b. This prevents, for example, the front side strip member 11b from getting caught and damaged during transportation.

[0032] <Second Embodiment> The decorative material 100 according to this embodiment is composed of the same woven bamboo member 10 and sheet member 20 as the decorative material 100 according to the first embodiment, but is a modified example in which the adhesive structure of these members is different.

[0033] More specifically, in this embodiment, when looking at the portion 10x where the strip members 11 overlap, the back surface of the back strip member 11a is bonded to the sheet member 20, which is consistent with the first embodiment. However, the adhesive structure differs from the first embodiment in that the front surface of the back strip member 11a is bonded to the front strip member 11b.

[0034] Therefore, the adhesive structure between the woven bamboo member 10 and the sheet member 20 will be explained in more detail while describing the manufacturing method of the decorative material 100 according to this embodiment with reference to Figure 4.

[0035] First, as shown in Figure 4(a), multiple strip members 11 are braided together on a flat surface to form a woven bamboo member 10. Next, as shown in Figure 4(b), adhesive is applied to the sheet member 20. Then, as shown in Figure 4(c), the sheet member 20 with the adhesive applied is pressed (pressed) against the woven bamboo member 10.

[0036] As a result, as shown in Figures 3 and 4(d), when looking at the overlapping portion 10x of the strip members 11, adhesive seeps between the back strip member 11a and the front strip member 11b, and this adhesive causes the back strip member 11a and the front strip member 11b to bond to each other. Specifically, in this embodiment, the decorative material 100 has the back strip member 11a and the front strip member 11b bonded to each other on their opposing surfaces. More specifically, the surfaces of both edges 11ax extending in the longitudinal direction of the back strip member 11a and the back surface of the front strip member 11b that is opposite to the surfaces of those edges 11ax are bonded to each other. However, the surface of the central portion 11ay extending in the longitudinal direction of the back strip member 11a and the back surface of the front strip member 11b that is opposite to the surface of that central portion 11ay are not bonded. Therefore, the adhesive area of ​​the back-side strip member 11a to the front-side strip member 11b is smaller than the adhesive area to the back-side sheet member 20, resulting in weaker adhesion in the latter than in the former. The adhesion between the back-side strip member 11a and the front-side strip member 11b is detached by bending the decorative material 100 beyond a predetermined amount.

[0037] With this configuration, bending causes the adhesive between the overlapping portions 10x of the strip members 11 to separate, creating a gap. This gap provides play, making it easier to bend and less likely to crack when bent.

[0038] <Other Embodiments> The decorative material according to the present invention is not limited to those of the embodiments described above. For example, in the embodiments described above, a strip member that is tightly plain woven was used as the woven basket member, but a perforated woven basket member may be used, for example. In this case, a sheet member that is translucent may be used.

[0039] The aforementioned strip member may be made from, for example, processed plant material, or it may be carbonized and colored. When carbonizing, heating may be done, for example, with steam.

[0040] In the first embodiment described above, the space between the non-overlapping strip members and the sheet member was filled with adhesive, and the strip members constituting the non-overlapping portion and the back strip members constituting the overlapping portion were bonded together. However, as shown in Figure 5, for example, the space between the non-overlapping portion 10x of the strip members 11 and the sheet member 20 may not be filled with adhesive 30, and the strip member 11c constituting the non-overlapping portion 10y and the back strip member 11a constituting the overlapping portion 10x may not be bonded together.

[0041] In the embodiments described above, the overlapping portion of the strip members is a structure in which two strip members overlap, but it may also be a structure in which two or more strip members overlap. For example, when three strip members overlap, each strip member may be configured to adhere to the adjacent strip member, or two strip members may be adhered to each other, while the other strip member is not adhered.

[0042] In the second embodiment described above, all the band members that make up the overlapping portion are bonded to each other, but it is also possible that only some of the band members that make up the overlapping portion are bonded to each other.

[0043] Furthermore, various combinations or modifications of parts of the embodiments are permitted, as long as they do not contradict the spirit of the present invention. [Explanation of Symbols]
