[0003] Patent Document 1: Japanese Patent Application Publication No. 2012-127068 Summary of the Invention

[0004] <The problem the invention aims to solve>

[0005] As disclosed in Patent Document 1, structures that separate spaces in buildings such as ceilings, floors, and walls are formed, for example, by bonding building materials to a base material using an adhesive. Therefore, when manufacturing structures such as ceilings, an adhesive is applied to the bonding surface of the building materials at the construction site.

[0006] When manufacturing structures such as roofs, to achieve the intended design performance, a predetermined amount of adhesive is applied to predetermined locations on the bonding surfaces of the building materials. Therefore, metering the adhesive for application and managing the amount applied has been considered. However, this increases the workload and complicates the process, making it difficult to apply in actual construction sites. Another approach has been to apply the adhesive without measuring its weight. In this case, the application relies on the contractor's experience and intuition, leading to concerns about over- or under-application of adhesive.

[0007] In view of the problems of the prior art, one aspect of the present invention is to provide a building material that can apply a predetermined amount of adhesive at a predetermined position on the bonding surface while suppressing deviations caused by the installer. <Methods for solving problems>

[0008] To address the aforementioned issues, according to one aspect of the present invention, a building surface material is provided, which is a building surface material having a plate-like shape. A plurality of first marks representing adhesive coating areas are disposed on the first main surface, which is one of the main surfaces. <The Benefits of Invention>

[0009] According to one aspect of the invention, a building material can be provided that applies a predetermined amount of adhesive at a predetermined position on the bonding surface, while suppressing deviations caused by the installer. Simple Explanation of the Diagram

[0011] Hereinafter, specific embodiments will be described with reference to the accompanying drawings. The present invention is not limited to the following embodiments, and various modifications and substitutions can be applied to the following embodiments without departing from the scope of the present invention. [Building Surface Materials] An example of the construction material of this embodiment will be described in detail with reference to the accompanying drawings. FIG1 is a perspective view of the construction material of this embodiment, FIG2 is an explanatory diagram of an example of the construction of the first main surface of the construction material of this embodiment. FIG3A to FIG3F are explanatory diagrams of an example of the construction of the first marked surface. FIG4 is an explanatory diagram of an example of the construction of the second main surface of the construction material of this embodiment.

[0012] In the construction of partition structures serving as spatial dividers in buildings such as ceilings, floors, and walls, adhesives have traditionally been applied to the bonding surfaces of building materials on-site. To achieve the intended design performance, a predetermined amount of adhesive is applied at predetermined locations on the bonding surfaces of the building materials during the construction of partition structures such as ceilings. Therefore, metering the adhesive and applying it to manage the application amount has been considered, but this increases the workload and complicates the process, making it difficult to apply in actual construction sites. Therefore, applying the adhesive without measuring its weight has also been considered. In this case, the application relies on the contractor's experience and intuition, leading to concerns about over- or under-application of adhesive.

[0013] Therefore, the inventors of this invention have studied a building material that can suppress deviations caused by the installer at a predetermined location on the bonding surface while applying a predetermined amount of adhesive. The results showed that by placing a first mark indicating the adhesive application area on the first main surface of the bonding surface of the building material, it is possible to suppress deviations caused by the installer at a predetermined location on the bonding surface, thereby completing this invention.

[0014] The building material of this embodiment is a building material with a plate-like shape, and a plurality of first marks indicating the adhesive coating area can be disposed on a first main surface, which is one of the main surfaces.

[0015] As shown in Figure 1, the building surface material 10 of this embodiment has a plate-like shape, having a first main surface 101 as one main surface and a second main surface 102 as the surface opposite to the first main surface 101. Note that reference numerals such as "first" are omitted in Figure 1. When manufacturing partition structures such as ceilings, floors, and walls, the building surface material of this embodiment is bonded to a base material using an adhesive; however, the first main surface 101 is coated with adhesive, becoming the bonding surface that bonds to the base material.

[0016] The shapes of the first main surface 101 and the second main surface 102 are not particularly limited. For example, as shown in Figures 1 and 2, the first main surface 101 can have a rectangular shape. In this case, the second main surface 102 can also have a rectangular shape. In addition, the rectangular shape referred to here is not limited to a geometrically strict rectangular shape, but includes shapes that can be considered as rectangular, taking into account the tolerances of building materials.

[0017] Furthermore, as shown in FIG2, the building material 10 of this embodiment has a plurality of first marks 21 on the first main surface 101 indicating the area where the adhesive is applied.

[0018] By configuring a first mark 21 that indicates the area for adhesive application, the adhesive can be applied in the appropriate predetermined position regardless of the operator's skill level.

[0019] Furthermore, by applying adhesive within the adhesive application area indicated by the first mark, the amount of adhesive applied to the first main surface 101 can easily reach a predetermined amount. Therefore, the building surface material according to this embodiment can suppress deviations caused by the construction worker while applying a predetermined amount of adhesive.

[0020] As described above, a predetermined amount of adhesive can be applied to the first main surface 101, which serves as the bonding surface, thereby making it easy to manage the amount of adhesive applied. Furthermore, the amount of adhesive applied to the building material can be kept within a predetermined range, thus allowing for control over adhesive consumption and easy management of adhesive inventory. (1) Regarding the first marker (1-1) Regarding configuration As shown in Figure 2, the first marker 21 can be configured in multiples.

[0021] The placement of the first mark 21 is not particularly limited; for example, it can be placed in a position that conforms to the specifications of the manufactured structure such as a roof. For example, as shown in FIG2, the first mark 21 is preferably placed in a grid pattern on the first main surface 101. That is, it is preferable to place the first mark 21 at the grid points of the intersection of a plurality of imaginary lines on the first main surface 101 in a grid pattern.

[0022] In this way, by arranging the first mark 21 in the shape of a Go board on the first main surface 101, it is possible to evenly and uniformly apply the adhesive at predetermined positions throughout the entire first main surface 101.

[0023] Specifically, as shown in FIG2, a first mark 21 is preferably placed at each intersection point of the first line 221-223 of the complex roots arranged along the first side 22 of the first main surface 101 and the second line 231-233 arranged along the second side 23 of the first main surface 101.

[0024] Furthermore, as shown in Figure 2, the first side 22 and the second side 23 form the edges of the first main surface 101, which has a rectangular shape. The aforementioned first straight lines 221-223 and second straight lines 231-233 are imaginary lines and do not necessarily need to be represented by printing on the first main surface 101.

[0025] The center-to-center distance between adjacent first marks 21, i.e. the distances L221 and L222 between the first straight lines, and the distances L231 and L232 between the second straight lines, are not particularly limited, but are preferably, for example, 50 mm or more and 500 mm or less.

[0026] By ensuring that the center-to-center distance between adjacent first marks 21 is 50 mm or more, when bonding the building surface material to the substrate, it is possible to more reliably prevent the cured adhesive from bonding together in the adhesive application areas of each first mark 21. That is, it is possible to more reliably prevent the diffusion of the adhesive across the entire first main surface 101, ensuring it remains as a single unit. Therefore, vibrations such as sound can be attenuated, improving the sound insulation of the partition structure.

[0027] Furthermore, by ensuring that the center-to-center distance between adjacent first marks 21 is less than 500 mm, a sufficient amount of adhesive can be applied to the first main surface of the building material 10, thereby improving the bonding strength with the substrate. Therefore, even in the event of a fire, the partition structure is particularly less prone to damage, thus improving fire resistance.

[0028] The distances L221, L222, L231, and L232, which are equivalent to the center-to-center distances of adjacent first marks 21, are preferably selected based on, for example, the amount of adhesive required for the first main surface of the building material 10, and can be selected within the range described above.

[0029] Along the direction of the first side 22, that is, the center-to-center distance of the first mark 21 adjacent to the X-axis is preferably equal. Therefore, the distance L231 between the second straight lines is preferably equal to the distance L232.

[0030] Furthermore, the center-to-center distance of the first mark 21 adjacent to the Y-axis along the direction of the second side 23 is preferably equal. Therefore, the distance L221 between the first straight lines is preferably equal to the distance L222.

[0031] However, the center-to-center distance between adjacent first marks 21 can be different along the X and Y axes. Therefore, the distances L221 and L222 between the first straight lines and the distances L231 and L232 between the second straight lines can be different.

[0032] In addition, due to the paper width, the distances between the first and second lines, the distances between the first and second lines in Figure 2 only represent a portion of the total distance.

[0033] As shown in Figure 2, the first mark 21 can be arranged to cover the entire first main surface 101. Therefore, the shortest distance L24 between the center of the first mark 21 and the first side 22 (which is the shorter side), and the shortest distance L25 between the center of the first mark 21 and the second side 23 (which is the longer side) are not particularly limited. The aforementioned shortest distance L24 corresponds to the shortest distance between the end of the building material 10 and the center of the first mark 21 in the length direction of the building material 10, i.e., in the Y-axis direction. The aforementioned shortest distance L25 corresponds to the shortest distance between the end of the building material 10 and the center of the first mark 21 in the width direction of the building material 10, i.e., in the X-axis direction.

[0034] Sometimes, depending on the type, purpose, and specifications of the resulting partition structure, and the type of adhesive used, the amount of adhesive required to be applied to the first main surface of the building material 10, and the shortest distance from the ends of the building material such as the first side 22 and the second side 23 to the center of the first mark, will vary. Therefore, it is preferable to select the shortest distance from the ends of the building material such as the aforementioned shortest distances L24 and L25 to the center of the first mark, depending on the type of partition structure formed. In addition, the aforementioned shortest distances L24 and L25 can be selected by adjusting, for example, the cutting position during the manufacturing of the building material or the position where the first mark 21 is printed.

[0035] The shortest distance L24 between the center of the first mark 21 and the first side 22 is preferably 500 mm or less, and the shortest distance L25 between the center of the first mark 21 and the second side 23 is preferably 100 mm or less. On the other hand, if it is disposed near the first side 22 and the second side 23 of the first main surface 101, adhesive may sometimes seep out when the building material 10 is attached to the substrate. The shortest distance L24 between the center of the first mark 21 and the first side 22, and the shortest distance L25 between the center of the first mark 21 and the second side 23 are not particularly limited as described above. However, from the viewpoint of preventing adhesive seepage in particular, the shortest distances L24 and L25 are preferably, for example, 10 mm or more, and more preferably 20 mm or more.

[0036] Additionally, as described above, the first mark 21 can be positioned near the first side 22 and the second side 23. When the first mark 21 is positioned near the first side 22 and the second side 23, and especially when it is necessary to prevent adhesive seepage, a distance from the first side 22 and the second side 23 to the center of the first mark 21 can be specified so that the first mark 21 within a predetermined range is not coated with adhesive. Specifically, a distance from the first side 22 and the second side 23 to the center of the first mark 21 can be specified so that, for example, the first mark 21 within a range less than 20 mm is not coated with adhesive. (1-2) Regarding the shape of the first mark The first mark 21 is only required to represent the shape of an adhesive coating area with a certain area in a manner that indicates the adhesive coating area; its shape is not particularly limited. The first mark 21 can have one or more shapes, for example, selected from circles, ellipses, polygons, stars, and crosses. In addition, the first mark 21 can be in the form of combinations of different shapes, such as quadrilaterals and circles.

[0037] The first mark, by having the aforementioned circular or other shape, allows for easy application of adhesive within the adhesive application area represented by that shape.

[0038] As shown in Figure 3A as the first mark 31 and Figure 3B as the first mark 32, the first mark can have a circular shape. The first mark 32 shown in Figure 3B has a shape in which three circles are arranged concentrically.

[0039] When the first mark has a circular shape, the interior of the circle is the adhesive application area. By applying adhesive within this circle, a predetermined amount of adhesive can be applied. For example, in the case of the first mark 31 shown in FIG3A, by applying adhesive in a manner that covers either the circle 312 enclosed by the line or the circle 311 containing the line, a predetermined amount of adhesive can be applied. As shown in FIG3A, when the line representing the circle is thick, the adhesive application area of ​​either the circle 311 containing the thick line or the circle 312 enclosed by the thick line can be selected according to the required amount of adhesive applied.

[0040] As shown in Figure 3A with the first mark 31, the lines constituting the first mark can include thicker lines. That is, the line width t can be increased.

[0041] By including a thick line in the line constituting the first mark, a difference in area can be created between the inside and outside of the thick line. That is, by including a thick line in the line constituting the first mark, it is easy to represent two adhesive-coated areas with different areas, i.e., different amounts of adhesive.

[0042] Furthermore, the lines constituting the first mark can also be composed solely of thick lines. Here, "thick line" refers to a line with a large line width t. Preferably, this thick line has a line width t such that the area of ​​the inner periphery of the thick line (e.g., circle 312) and the outer periphery of the thick line (e.g., circle 311) differs to a certain extent. The line width t of the thick line can be selected based on the area of ​​the adhesive coating region being represented, and is not particularly limited; for example, it is preferably 0.7 mm to 14 mm.

[0043] This is because by making the line width t of the thick line 0.7 mm or more, the installer can easily recognize it as a thick line. In addition, by making the line width t of the thick line 0.7 mm or more, the installer can produce a significant difference in the amount of adhesive applied when the adhesive is applied to the inner circumference of the thick line and when the adhesive is applied to the outer circumference of the thick line.

[0044] By keeping the line width of the thick lines below 14mm, the amount of ink used when printing the first mark can be reduced, thus lowering costs.

[0045] Thick lines include not only solid lines with large line width, but also dashed lines and dotted lines with large line width. In addition, various chain lines such as one-point chain lines and two-point chain lines are also included in the dashed lines, as are other parts of this specification.

[0046] Furthermore, as shown in Figure 3B, when the first mark 32 includes a plurality of circles, that is, when it includes a plurality of adhesive coating areas, adhesive can be applied to circles 321, 322, and 323 by covering the circles selected according to the required coating amount, thereby enabling the coating of a predetermined amount of adhesive.

[0047] For example, as shown in Figure 3C, the first mark 33 can also have a cross shape. Figure 3C shows a mark with two cross shapes combined. Furthermore, when the first mark has a cross shape, for example, by applying adhesive to cover the adhesive application area surrounded by the dotted line 3321 (overlapping the cross shape 332), a predetermined amount of adhesive can be applied. Alternatively, for example, by applying adhesive to cover the adhesive application area surrounded by the dotted line 3311 (overlapping the cross shape 331), a predetermined amount of adhesive can be applied. In the case of the first mark 33 shown in Figure 3C, the method of applying adhesive to cover either the cross shape 331 or the cross shape 332 can be selected according to the required amount of adhesive. Additionally, the dotted lines 3311 and 3321 are lines provided for illustration purposes and are printed; they do not necessarily need to be shown.

[0048] Furthermore, as shown in Figure 3D, the first mark 34 can also be polygonal. Figure 3D shows a mark with a combination of two quadrilaterals.

[0049] As shown in Figure 3D, in the case of multiple polygons, in rectangles 341 and 342, adhesive can be applied by covering the selected rectangle according to the required coating amount, thereby applying a predetermined amount of adhesive.

[0050] For example, as shown in FIG3E, the first mark 35 can also be star-shaped. For example, it can be constructed by applying adhesive in a manner that covers the star 351, thereby applying a predetermined amount of adhesive. In addition, similar to the case of the first mark 33 having a cross shape as shown in FIG3C, it can be specified that the adhesive is applied in a circular manner that covers the star 351.

[0051] Figure 3E shows an example where the first mark 35 has one star 351. As shown in Figures 3B to 3D, the first mark can also have multiple stars. When the first mark has multiple stars, the adhesive can be applied by covering the selected stars according to the required coating amount, thereby applying a predetermined amount of adhesive.

[0052] For example, as shown in FIG3F, the first mark 36 can also be elliptical. For example, by applying adhesive in a manner that covers the ellipse 361, a predetermined amount of adhesive can be applied. FIG3F shows an example where the first mark 36 has one ellipse 361. As shown in FIG3B-3D, the first mark can also have multiple ellipses. When the first mark has multiple ellipses, depending on the required coating amount, a predetermined amount of adhesive can be applied by applying adhesive in a manner that covers the selected ellipse.

[0053] Furthermore, the examples shown in Figures 3A to 3F, where the first mark is represented by a solid line, are not limited to this form. The first mark may be represented in a way that can identify the adhesive coating area, such as a collection of points, a dashed line, a dotted line, or a color.

[0054] The first mark 21 preferably includes two or more adhesive coating areas of different areas. Specifically, for example, as shown in circles 311 and 312 in FIG. 3A, it preferably includes two or more adhesive coating areas of different areas. As shown in FIG. 3B to FIG. 3D, the first marks 32, 33, and 34 can also be configured to include a plurality of adhesive coating areas of different sizes. In addition, the examples of the first mark in FIG. 3A to FIG. 3D showing the first mark including two or three adhesive coating areas of different areas are not limited to this form, and the first mark 21 can be configured to include four or more adhesive coating areas of different areas.

[0055] Two or more adhesive coating areas with different areas do not need to be distinguished by lines like those in Figures 3A to 3D. For example, they can be represented in a way that can be identified by color, layering, etc.

[0056] Depending on the type, purpose, and specifications of the resulting partition structure, and the type of adhesive used, the amount of adhesive required to be applied to the first main surface of the building material 10 may vary. Therefore, by including two or more adhesive application areas of different sizes in the first mark 21, the adhesive application area within the first mark 21 can be selected according to the required amount of adhesive, making it easy to apply a predetermined amount of adhesive.

[0057] Furthermore, as previously stated, depending on the amount of adhesive required to be applied to the first main surface of the building material 10, the distances L221, L222, L231, and L232 corresponding to the center-to-center distance of adjacent first marks 21 can be selected.

[0058] The plurality of first marks 21 disposed on the first main surface 101 of the building material 10 may also include marks with different shapes and structures. From the point of view of operability and productivity, the shape and structure of the first marks 21 within the first main surface 101 may also be composed of the same marks. (1-3) Regarding the number of the first mark The number of multiple first marks 21 disposed on the first main surface 101 of the building material 10 is not particularly limited. For example, the number of first marks 21 disposed on the first main surface 101 is selected in such a way that the product of the amount of adhesive applied to each adhesive application area calculated with respect to the area of ​​the adhesive application area represented by each first mark 21 and the number of first marks 21 is a predetermined amount of adhesive applied.

[0059] Furthermore, the total amount of adhesive applied to the first main surface 101 of the building material 10 depends on the type, purpose, and specifications of the partition structure, as well as the type of adhesive used, and is therefore not particularly limited. The amount of adhesive applied per unit area to the first main surface 101 of the building material 10 is preferably, for example, 10 g / m² or more and 1000 g / m² or less, more preferably 25 g / m² or more and 600 g / m² or less.

[0060] As described above, depending on the type, purpose, and specifications of the formed partition structure, and the type of adhesive used, the amount of adhesive required to be applied to the first main surface of the building material 10 may vary. Furthermore, the first main surface 101 of the building material 10 in this embodiment is provided with a plurality of first marks 21. Therefore, the number of first marks 21 to be applied can be selected according to the required amount of adhesive. For example, if half the amount of adhesive is required to be applied to the adhesive application area of ​​all the first marks 21 on the first main surface, then adhesive can be applied to half the number of first marks 21. That is, adhesive can also be applied to half the number of first marks 21 in the adhesive application area of ​​the first main surface 101. In the adhesive coating area of ​​the first mark 21, when a portion of the adhesive is coated, it is preferable to select the first mark 21 of the adhesive coating in a manner that prevents the coated first mark 21 from shifting within the first main surface 101.

[0061] Furthermore, depending on the coating amount, the building material of this embodiment can have different first marks on its first main surface in a way that allows for easy selection of the first mark used to apply the adhesive. The building material of this embodiment can also have multiple types of first marks, for example, selected from one or more different types of lines, colors, shapes, and sizes. Line types include different representations such as thickness (line width), dotted lines, and solid lines.

[0062] As described above, by placing a first mark 21, which has a certain area indicating the adhesive application area, on the first main surface 101 of the building material 10, adhesive can be applied to a predetermined amount at a predetermined location regardless of the installer's method, by applying adhesive to the adhesive application area indicated by the first mark 21. Therefore, in the case of forming a partition structure such as a wall, the bonding strength with the substrate is sufficiently improved, and the fire resistance is enhanced. Furthermore, as described above, a plurality of first marks 21 are disposed on the first main surface 101 of the building material 10. Since a predetermined amount of adhesive can be applied to each first mark 21, when the building material 10 is bonded to the substrate, it is prevented that the entire first main surface of the building material 10 is bonded with each other, thereby improving the sound insulation of the resulting partition structure. (2) Regarding the second marker In this embodiment, the building surface material 10 may have a plurality of second marks indicating the positions of metal fasteners for nailing and fixing on the second main surface 102, which is the main surface located on the opposite side of the first main surface 101.

[0063] In the manufacture of partition structures, sometimes the building material is bonded to the base material with an adhesive, and then further fixed to the base material using metal fasteners (fixtures) such as nails or staplers. Therefore, the building material of this embodiment can also have a second mark on the second main surface 102, which is the side opposite to the first main surface 101 of the bonding surface, indicating the position where the metal fastener is inserted.

[0064] By placing the second mark 41 on the second main surface 102, fixing metal tools can be easily driven into the appropriate position regardless of the construction worker's skill. Therefore, when forming partition structures such as walls, the adhesion strength with the substrate is significantly improved. (2-1) Regarding configuration The arrangement of the second mark is not particularly limited. For example, as shown in Figure 4, the second mark 41 can be arranged in a grid pattern on the Go board. That is, the second mark 41 can be arranged on the second main surface 102 in a grid pattern at the intersection points of a complex number of lines that are hypothetically derived.

[0065] Specifically, as shown in FIG4, it is preferable to place a second mark 41 at each intersection point of the first line 421-423 of the complex roots arranged along the first side 42 of the second main surface 102 and the second line 431-433 arranged along the second side 43 of the second main surface 102.

[0066] Furthermore, as shown in Figure 4, the first side 42 and the second side 43 form the edges of the second main surface 102, which has a rectangular shape. The first straight lines 421~423 and the second straight lines 431~433 mentioned above are imaginary lines printed on the second main surface 102 and do not necessarily need to be represented.

[0067] The center-to-center distance of the second mark 41 adjacent to the X-axis along the direction of the first side 42 is preferably equal. Therefore, the distance L431 between the second straight lines is preferably equal to the distance L432.

[0068] Furthermore, the center-to-center distance of the second mark 41 adjacent to the Y-axis along the direction of the second side 43 is preferably equal. Therefore, the distance L421 between the first straight lines is preferably equal to the distance L422.

[0069] However, the center-to-center distances of adjacent second marks 41 can be different along the X and Y axes. Therefore, the distances L421 and L422 between the first straight lines and the distances L431 and L432 between the second straight lines can be different.

[0070] In addition, due to the paper width, the distances between the first and second lines, the distances between the first and second lines in Figure 4 only represent a portion of the total distance.

[0071] As shown in Figure 4, the second mark 41 can be configured to cover the entire second main surface 102. (2-2) Regarding the shape of the second mark The second mark 41 indicates the position where the metal fixture is nailed in, so its shape is not particularly limited. For example, it can have one or more shapes selected from circles, ovals, polygons, stars, crosses, and straight lines. In addition, shapes such as individual points among circles, ovals, polygons, stars, and crosses are also included.

[0072] Figure 4 shows an example of representing a collection of points other than the second mark as a quadrilateral, but it is not limited to this form. The second mark can be represented by one or more methods, such as solid lines, dashed lines, dotted lines, colors, etc., to identify the position of the metal fixture being nailed in. (3) Regarding the types of building surface materials The building surface material used in this embodiment is not particularly limited, and examples include fiber-reinforced cement board, glass-padded gypsum board, gypsum board containing glass fiber nonwoven fabric, glass fiber-infused cement board, fiber-infused calcium silicate board, gypsum board as specified in JIS A 6901 (2014), gypsum board that is lighter or heavier than the gypsum board specified in JIS A 6901 (2014) (hereinafter, the above-mentioned gypsum board specified in JIS and gypsum board that is lighter or heavier than the gypsum board specified in JIS are collectively referred to as "gypsum board"), gypsum board, slag gypsum board, and resin board. Therefore, the building surface material is preferably, for example, fiber-reinforced cement board, glass-padded gypsum board, gypsum board containing glass fiber nonwoven fabric, glass fiber-infused cement board, fiber-infused calcium silicate board, gypsum board, gypsum board, slag gypsum board, or resin board.

[0073] In particular, gypsum board is widely used in building ceilings, walls, floors, etc. From the viewpoint of improving fire resistance and sound insulation, it is especially required to apply an appropriate amount of adhesive at the appropriate location on the interface with the substrate. Moreover, as described above, the building surface material 10 according to this embodiment, by providing a predetermined first mark 21 on the first main surface 101, allows for easy application of a predetermined amount of adhesive at a predetermined location regardless of the installer's skill. Therefore, the building surface material 10 of this embodiment is more preferably gypsum board. [Manufacturing methods for building facing materials] Next, the manufacturing method of the building surface material according to this embodiment will be described. Furthermore, the building surface material manufacturing method of this embodiment can manufacture the previously described building surface material. Therefore, details already described will be omitted.

[0074] The method for manufacturing building materials according to this embodiment can include the following building material manufacturing steps and a first marking printing step.

[0075] In the manufacturing process of building materials, building materials with a plate-like shape can be manufactured.

[0076] In the first mark printing process, the first mark can be printed in such a way that a plurality of first marks representing adhesive coating areas are arranged on the first main surface of the main surface of the building material.

[0077] The following is a description of each process. (1) Manufacturing process of building surface material In the manufacturing process of building materials, as described above, building materials with a plate-like shape can be manufactured.

[0078] When the building surface material being manufactured is gypsum board, the manufacturing process can include the following steps. Furthermore, when the building surface material is not gypsum board, the manufacturing process can be a specific step corresponding to the building surface material being manufactured. The following explanation uses gypsum board as an example to illustrate the manufacturing process for building surface materials.

[0079] The mixing process involves blending raw materials containing calcined gypsum and water to form gypsum slurry.

[0080] Molding process of forming plaster slurry into a molded body.

[0081] A curing process that solidifies the molded body obtained from the molding process.

[0082] The following is a description of each process. (1-1) Mixing process and molding process The mixing process allows raw materials containing calcined gypsum and water to be mixed. (calcined plaster) The calcined gypsum contained in the raw material is also known as calcium sulfate 1 / 2 hydrate, which is an inorganic composition with hydraulic properties. As calcined gypsum, any single or mixed product of α-type or β-type calcined gypsum, obtained by calcining natural gypsum, by-product gypsum, and flue gas desulfurization gypsum, either individually or in water (including steam), can be used. Furthermore, it is not a problem for the calcined gypsum to contain trace amounts of anhydrous type III gypsum generated during the calcination process.

[0083] In addition, α-type calcined gypsum requires the use of an autoclave to pressurize and fire dihydrate gypsum such as natural gypsum in water or steam. Furthermore, β-type calcined gypsum can be manufactured by firing dihydrate gypsum such as natural gypsum at atmospheric pressure. (water) Water can be added to form a gypsum slurry by mixing calcined gypsum and other materials. The amount of water added when forming the gypsum slurry is not particularly limited and can be any amount depending on the desired fluidity. (Other ingredients) Besides calcined gypsum and water, which have been described so far, gypsum slurry can contain any other ingredients.

[0084] For example, foam can be added when forming gypsum slurry. By adjusting the amount of foam added, the specific gravity of the gypsum board can be brought into the desired range.

[0085] There are no particular limitations on the method of adding foam when forming gypsum slurry; it can be done by any method. For example, a foaming agent can be added to water (water for foam formation) beforehand, and air can be drawn in while stirring to form foam. The foam is then mixed with calcined gypsum and water (the water used to refine the gypsum slurry) to form a foamed gypsum slurry. Alternatively, the foam can be added to a gypsum slurry formed by pre-mixing calcined gypsum and water to create a foamed gypsum slurry.

[0086] There are no particular limitations on the foaming agents used to form bubbles, but examples include sodium alkyl sulfate, alkyl ether sulfate, sodium alkylbenzene sulfonate, and polyoxyethylene alkyl sulfate.

[0087] There is no particular limit to the amount of foam added, and the amount of gypsum board that can be made can be selected arbitrarily according to the required specific gravity.

[0088] In addition, the raw materials may also contain adhesive modifiers such as starch and polyvinyl alcohol to improve the adhesion between the coating material and the gypsum core, inorganic fibers such as glass fiber and lightweight aggregates, refractory materials such as vermiculite, setting regulators, water-reducing agents, accelerators, retarders and other curing regulators, thickeners, defoamers, pigments, foam size regulators such as sulfosuccinate surfactants, organosilicon, paraffin wax and other water-repellent agents, fillers (volume-increasing materials) and other additives that have always been added to the raw materials of gypsum board.

[0089] When mixing raw materials to prepare gypsum slurry, all components constituting the raw materials can be mixed simultaneously, or the mixing can be carried out in multiple stages. For example, solid components can be mixed with raw materials to form a gypsum composition, and then liquid components such as water from the raw materials can be added to the resulting gypsum composition for further mixing to produce gypsum slurry.

[0090] In addition, there are no particular restrictions on the means of mixing the raw materials; for example, a mixer can be used.

[0091] The obtained gypsum slurry can be molded into a desired shape during the molding process. Specifically, in order to make gypsum board, it can be molded, for example, into a board shape.

[0092] Here, Figure 5 will be used to illustrate the composition of the mixing and molding processes in the manufacture of gypsum board.

[0093] In the diagram, from right to left, the surface covering paper (board paper) 51, which serves as the covering material (surface material), is transported along the production line.

[0094] The mixer 52 can be configured at a predetermined position associated with the conveyor line, for example, above or across the conveyor line. Moreover, in a single mixer 52, calcined gypsum, water, and various further additives as appropriate, which are raw materials for gypsum slurry, can be mixed to produce gypsum slurry (mixing process).

[0095] Alternatively, as described above, a gypsum composition can be prepared by pre-mixing and stirring solids such as gypsum to form a mixture, and then supplied to the mixer 52.

[0096] Furthermore, by adding foam through the gypsum slurry dispensing ports 521, 522, and 523, and adjusting the amount of foam added, gypsum slurry of any density can be produced. For example, by adjusting the amount of foam added, first gypsum slurry 53 and second gypsum slurry 54 with different densities can be prepared.

[0097] Furthermore, the obtained first gypsum slurry 53 is supplied to the surface cover paper (board paper) 51 and the back cover paper (board paper) 56 on the upstream side of the conveying direction of the roller coating machine 55 through the delivery pipes 524 and 525.

[0098] Here, the roller coater 55 can have a coating roller 551, a receiving roller 552, and a take-up roller 553. The first gypsum slurry 53 on the top cover paper 51 and the back cover paper 56 each extends to the extension section of the roller coater 55, where it is extended. A thin layer of the first gypsum slurry 53 is formed on the top cover paper 51. Similarly, a thin layer of the first gypsum slurry 53 is formed on the back cover paper 56. In addition, Figure 5 shows an example of using the roller coater 55 to coat the first gypsum slurry 53 on both the top cover paper 51 and the back cover paper 56, but it is not limited to this configuration. For example, the roller coater 55 can be used to coat the first gypsum slurry 53 only on either the top cover paper 51 or the back cover paper 56. Furthermore, the surface covering paper 51 can have a plurality of scribe lines parallel to the transport direction near its ends in the width direction, and the surface covering paper 51 can be bent along the scribe lines to cover a portion of the side and top of the second gypsum slurry 54 (described later). In this case, the first gypsum slurry 53 can also be disposed only on the side and top of the second gypsum slurry 54 in a thin layer, with the first gypsum slurry 53 disposed only at the side ends of the surface covering paper 51.

[0099] The surface cover paper 51 is transported directly, while the back cover paper 56 is turned along the conveyor line direction of the surface cover paper 51 by a turning roller 57. Furthermore, both the surface cover paper 51 and the back cover paper 56 are transported in the same direction to the forming machine 58. Here, the second gypsum slurry 54 is supplied from the mixer 52 through pipe 526 between the thin layers formed on the surface cover paper 51 and the back cover paper 56.

[0100] Moreover, the gypsum slurry can be molded using molding machine 58 to form a molded body (molding process).

[0101] Figure 5 shows an example of manufacturing the first gypsum slurry 53 and the second gypsum slurry 54 using one mixer 52. Two mixers can be set up to manufacture the first gypsum slurry 53 and the second gypsum slurry 54 using each mixer.

[0102] Furthermore, it is not limited to the form of using the first gypsum slurry 53 and the second gypsum slurry 54. For example, it can be used to produce a gypsum slurry of a certain density and supply it to the base paper for board.

[0103] Specifically, for example, plaster slurry of a predetermined density is supplied to a continuously transported surface cover paper (board base paper) and piled up. Furthermore, the surface cover paper, serving as the bottom sheet, is folded in along the etched lines connected at its two ends while being wound into the plaster slurry. At this time, a back cover paper (board base paper) transported at the same speed is superimposed on the layer of plaster slurry. Next, it is formed using a forming machine that determines the thickness and width of the plasterboard. Plasterboard can also be formed using the above steps.

[0104] In addition, taking gypsum board as an example, it is also possible to change the board base paper used as the covering material (surface material) to glass fiber nonwoven fabric (glass paper), glass pad, etc., and arrange it on the surface or close to the surface to manufacture various gypsum-containing boards. (1-2) Curing process Next, a curing process can be carried out to solidify the molded body, that is, to solidify the gypsum slurry water in the molded body.

[0105] The curing process is carried out by the hydration reaction of calcined gypsum (hemihydrate gypsum) in the gypsum slurry to produce needle-like crystals of dihydrate gypsum, which then solidify. Therefore, within the molded body formed in the molding process, the calcined gypsum contained in the gypsum slurry reacts with water to carry out the hydration reaction of the calcined gypsum, thereby implementing the curing process. (1-3) Other processes Furthermore, the manufacturing process for building materials can be further customized by incorporating processes such as rough cutting, drying, trimming, and stacking, as needed.

[0106] For example, after the molding process described above, during or after the curing process, a rough cutting process can be performed to roughly cut the molded body formed by the molding process using a rough cutting tool. In the rough cutting process, the continuous molded body formed by the molding process can be cut to a predetermined length using a rough cutting tool.

[0107] Furthermore, a drying process can be performed on molded bodies formed by the molding process, or molded bodies coarsely cut by the coarse cutting process, to remove any remaining moisture. Additionally, the drying process can supply molded bodies that have completed the curing process. The drying process can be performed by using a dryer to force-dry the molded body.

[0108] There are no particular limitations on the method of forced drying of molded parts using a dryer. For example, a dryer can be installed in the transport path of the molded parts, and the molded parts can be continuously dried as they pass through the dryer. Alternatively, molded parts can be loaded into the dryer and dried in batches.

[0109] Furthermore, for example, it is also possible to perform a cutting process after drying the molded body, cut it into products of a predetermined length, accumulate the obtained plasterboard using an elevator, store it in a warehouse, or take it out of the warehouse and stack it in a truck, etc.

[0110] In the aforementioned cutting process and the aforementioned rough cutting process, the product is continuously cut along the cutting line in the width direction by means of a cutting tool or cutting device. Furthermore, the width direction corresponds to the X-axis in Figure 2, and the length direction, described later, corresponds to the Y-axis in Figure 2. Therefore, the short side of one end in the length direction of the product obtained after the aforementioned cutting process and the aforementioned rough cutting process, and the rough-cut product, becomes the first side 22.

[0111] Furthermore, in the following section "(2) First Mark Printing Process", in "(2-1) When performed before the start of the building material manufacturing process" and "(2-2) When performed simultaneously with the building material manufacturing process", the first marking printing process can also be performed before the cutting process, etc. As described above, when the first marking printing process is performed before the cutting process, the shortest distance L24 between the finished product after the cutting process and the roughly cut product after the rough cutting process varies in the range of, for example, 0 mm to 500 mm. Therefore, by adjusting the cutting position, for example, the shortest distance L24 can be selected within the above range. The shortest distance L24 has already been explained using Figure 2, so the explanation is omitted here. (2) First Mark Printing Process In the first mark printing process, the first mark can be printed by distributing a plurality of first marks indicating adhesive application areas on the first main surface of the building material. Furthermore, the first mark is preferably printed in a Go board-like arrangement on the first main surface.

[0112] There is no particular limitation on when to carry out the first marking printing process. It can be carried out before the start of the building material manufacturing process, simultaneously with the building material manufacturing process, or after the end of the building material manufacturing process.

[0113] In addition, when the building material is gypsum board, the first mark printing process can be carried out by printing the first mark on the board base paper. (2-1) Under the condition of implementing the process before starting the manufacturing process of building face material If the first mark printing process is performed before the start of the building material manufacturing process, the first mark can be pre-printed on the back cover paper 56. In the building material manufacturing process, the building material can be manufactured by supplying the back cover paper 56 with the first mark printed on it so that the side with the first mark printed on it is on the outer surface. (2-2) When carried out simultaneously with the building surface material manufacturing process When the building material manufacturing process and the first mark printing process are performed simultaneously, for example, the first mark can be printed on the back cover paper 56 before the molding process described above. In this case, as shown in FIG. 5, the first mark printing device 591A can be arranged upstream of the molding machine 58 in the transport path of the back cover paper 56 to print the first mark. The first mark printing device 591A can be arranged at any position upstream of the molding machine 58, and its position is not limited. For example, as shown in FIG. 5, the first mark printing device 591A can be configured to print the first mark on the back cover paper 56 of the transported board paper before the first gypsum slurry 53, which is supplied as gypsum slurry.

[0114] Furthermore, after the forming process, a first mark can be printed on the back cover paper 56. In this case, as shown in FIG. 5, the first mark printing device 591B can be arranged downstream of the forming machine 58 in the transport path of the back cover paper 56 to print the first mark.

[0115] The configuration of the first mark printing apparatus 591A and 591B is not particularly limited. For example, inkjet printing can also be used. In addition, plate printing with a plate corresponding to the first mark to be printed can also be used, specifically, letterpress printing, gravure printing, and offset printing. When printing the first mark using plate printing, it is preferable to form a plate on the surface of the roller in a manner that does not hinder the transport of the backing paper 56 and the formed body, and then use the roller for printing. (2-3) When the building materials manufacturing process is completed, the following applies: The first marking printing process can also be performed after the building material manufacturing process is completed. That is, the first marking can also be printed on the manufactured building material.

[0116] By printing the first mark on the manufactured building materials, the accuracy of the printing position of the first mark can be improved.

[0117] This section mainly uses the case of gypsum board as the building material as an example. When the building material does not have a covering material on its surface, the first mark can be printed on the exposed first main surface of the building material.

[0118] Therefore, when the building material does not have a covering material, the first marking printing process can be carried out simultaneously with the building material manufacturing process, or after the building material manufacturing process is completed. (3) Second marking printing process The building material described above can also have a second mark on the second main surface. Therefore, the manufacturing method of the building material of this embodiment can also include a second mark printing process in which a plurality of second marks indicating the positions of metal fasteners for nailing are arranged on the second main surface, which is the main surface located on the opposite side of the first main surface. In addition, the second mark is preferably printed in a Go board pattern arrangement on the second main surface.

[0119] There is no particular limitation on when to carry out the second marking printing process. It can be carried out before the start of the building material manufacturing process, simultaneously with the building material manufacturing process, or after the end of the building material manufacturing process.

[0120] In addition, when the building material is gypsum board, the second marking printing process can be carried out by printing the second mark on the board base paper disposed on the surface of the gypsum board. (3-1) Under the condition of implementing the process before starting the manufacturing process of building face material If the second mark printing process is performed before the start of the building material manufacturing process, the second mark can be pre-printed on the surface cover paper 51. In the building material manufacturing process, the building material can be manufactured by supplying the surface cover paper 51 with the second mark printed on it so that the surface with the second mark printed on it is on the outer surface. (3-2) When carried out simultaneously with the building surface material manufacturing process When the building material manufacturing process and the second mark printing process are performed simultaneously, for example, the second mark can be printed on the surface cover paper 51 before the molding process described above. In this case, as shown in FIG. 5, the second mark printing device 592A can be arranged upstream of the molding machine 58 in the transport path of the surface cover paper 51 to print the second mark. The second mark printing device 592A can be arranged at any position upstream of the molding machine 58, and its position is not limited. As shown in FIG. 5, the second mark printing device 592A can be configured to print the second mark on the surface cover paper 51, which is the board base paper being transported before the first gypsum slurry 53, which is the gypsum slurry.

[0121] Furthermore, a second mark can be printed on the surface cover paper 51 after the forming process. In this case, as shown in FIG. 5, a second mark printing device 592B can be arranged downstream of the forming machine 58 in the transport path of the surface cover paper 51 to print the second mark.

[0122] The configuration of the second mark printing apparatus 592A and 592B is not particularly limited. Printing can also be performed, for example, by inkjet printing. Furthermore, printing can also be performed by plate printing, specifically, letterpress printing, gravure printing, or offset printing, using a plate having a corresponding plate for the second mark to be printed. When printing the second mark by plate printing, it is preferable to form a plate on the surface of the roller in a manner that does not obstruct the transport of the surface-covered base paper 51 and the formed body, and then perform printing using that roller. (3-3) When implemented after the construction of building materials is completed The second marking printing process can also be performed after the building material manufacturing process is completed. That is, the second marking can also be printed on the manufactured building material.

[0123] The accuracy of the printing position of the second mark can be improved by printing the second mark on the manufactured building material.

[0124] This section mainly uses gypsum board as an example to illustrate that, when the surface material of the building material is not covered, a second mark can be printed on the exposed second main surface of the building material.

[0125] Therefore, when the building material does not have a covering material, the second marking printing process can be carried out simultaneously with the building material manufacturing process, or after the building material manufacturing process is completed.

[0126] The method for manufacturing building materials according to the above-described embodiment can manufacture the aforementioned building materials. That is, it is possible to manufacture building materials on which a plurality of first marks indicating adhesive coating areas are disposed on the first main surface.

[0127] Therefore, the building surface material obtained by the manufacturing method of the building surface material according to this embodiment, by applying adhesive in the adhesive application area indicated by the first mark, can easily apply a predetermined amount of adhesive at a predetermined location while suppressing deviations caused by the construction worker. Therefore, when forming partition structures such as walls, the bonding strength with the substrate is sufficiently improved, and the fire resistance is enhanced.

[0128] Furthermore, a plurality of first marks are disposed on the first main surface of the building material. Since a predetermined amount of adhesive can be applied to each first mark 21, when bonding the building material to the substrate, it is prevented that each adhesive is bonded to the other on the entire first main surface of the building material, thereby improving the sound insulation of the resulting partition structure. [Manufacturing method of partition structure] Next, the manufacturing method of the partition structure using the previously described building materials will be explained using Figures 6 and 7.

[0129] The manufacturing method of the partition structure in this embodiment can include the following adhesive coating process and bonding process.

[0130] In the adhesive coating process, adhesive can be applied to the adhesive coating area marked as the first mark on the building surface material.

[0131] In the next process, the building face material can be placed on the substrate in such a way that the first main surface coated with adhesive is opposite to the substrate, and the building face material is then bonded to the substrate. (1) Regarding the partition structure The partition structure manufactured by the manufacturing method of the partition structure of this embodiment is not particularly limited as long as it is a structure that separates spaces in a building such as a steel frame structure, a reinforced concrete structure, or a wooden structure. Examples of partition structures include at least one type selected from ceilings, floors, and walls.

[0132] Here, as an example of a partition structure manufactured by the manufacturing method of the partition structure of this embodiment, the structure of a reinforced concrete structure wall will be described.

[0133] Figure 6 shows a cross-sectional view of a partition wall, an example of a partition structure, with the plane parallel to the height direction and perpendicular to the main surface of the wall. Figure 7 shows a perspective view of the partition wall. Furthermore, in Figure 7, for ease of understanding the structure of the partition wall, descriptions of the lower panel 64, upper panel 66, etc., which are positioned deeper than the canopy light iron base 72 and vertical ribs 61 shown in Figure 6, are omitted. Also, since the canopy light iron base 72 is omitted in Figure 7, the surface decorative material 68 is placed on the entire surface of the upper panel 66.

[0134] The partition wall 60 shown in Figure 6 is constructed on a reinforced concrete floor F1. The lower end of the partition wall 60 is fixed to the floor F1, and the upper end of the partition wall 60 is fixed to the upper reinforced concrete floor F2. The partition wall 60's axial assembly consists of steel vertical ribs 61, floor lining material 621, and upper lining material (roof lining material) 622. The vertical ribs 61 are formed of lightweight steel channel-type components, and the floor lining material 621 and upper lining material 622 are formed of lightweight channel steel. The floor lining material 621 and upper lining material 622 are fixed to the floor F1 and F2 respectively by anchor bolts or other locking devices 63, and the lower and upper ends of the vertical ribs 61 are respectively locked to the floor lining material 621 and upper lining material 622. The vertical ribs 61 are arranged along the wall core direction at predetermined intervals (e.g., 455mm intervals) with dimensions of about 300~600mm, and are erected vertically between the floor F1 and F2.

[0135] The lower panel 64 is installed on both sides of the vertical rib 61 by screws 65, and the upper panel 66 is fixed to the surface of the lower panel 64 by a stapler or similar clamping device 67 and an adhesive. As the lower panel 64, non-combustible building materials (building material boards) such as fiber-reinforced cement board, glass-coated gypsum board, gypsum board with added glass fiber nonwoven fabric, glass fiber mixed cement board, fiber mixed calcium silicate board, gypsum board, slag gypsum board, or resin board can be used.

[0136] The surface of the upper panel 66 can be coated with or covered with other surface decorative materials 68.

[0137] The interior of the partition wall 60 can be fitted with thermal insulation materials 69 such as glass wool or rock wool. Furthermore, floor coverings 70 can be installed on the floor F1, and footboards 71 ​​can be installed at the lower edge of the partition wall 60. As the footboards 71, commonly used prefabricated footboards, such as vinyl footboards, can be used.

[0138] Furthermore, the canopy light iron base 72 can be suspended from the upper floor F2. Moreover, the surface of the canopy light iron base 72 can be fitted with canopy decorative material 73.

[0139] The ceiling decoration material 73 is connected to the interior side wall by dividing lines 74 around the ceiling perimeter. The dividing lines 74 can be prefabricated dividing lines made of resin or metal, or processed products made of wood or connectors.

[0140] Furthermore, as shown in Figure 7, the lower plate 64 is installed along the transverse tension direction, and the upper and lower lower plates 64 are joined together at the transverse joints 75. The plurality of transverse joints 75 extend horizontally and parallelly as joints in the jointing method.

[0141] The upper plate 66 is installed along the longitudinal tension direction, and longitudinal joints 76 are interconnected by the desired joint forms such as split joints, connecting joints, and joint construction method joints. The plurality of longitudinal joints 76 extend vertically and parallelly.

[0142] Furthermore, as the top panel 66, it is suitable for use with the aforementioned building materials.

[0143] By using the aforementioned building material as the upper panel 66, an appropriate amount of adhesive can be applied at suitable locations between the lower panels 64 and the substrate, regardless of the installer's skill level. Therefore, a partition structure with excellent fire resistance and sound insulation can be manufactured.

[0144] Furthermore, this description uses the construction of a partition wall as a dividing structure as an example, but the dividing structure in this embodiment is not limited to a partition wall, and includes various dividing structures that use the building materials described above. (2) Regarding the manufacturing method of the partition structure The manufacturing method of the partition structure in this embodiment can include the described adhesive coating process and bonding process.

[0145] The process for each step is explained. (2-1) Adhesive coating process In the adhesive coating process, adhesive can be applied to the adhesive coating area marked as the first mark on the building surface material.

[0146] There are no particular limitations on the method of applying the adhesive; for example, a brush or a dedicated application tool with a shape corresponding to the shape of the first mark can be used. Alternatively, the outlet of the tube containing the adhesive can be directly pressed against the first mark for application.

[0147] There are no particular limitations on the type of adhesive, as long as it is a liquid when applied, cures, and can exhibit adhesion to the substrate. For example, sealants, organic adhesives, and inorganic adhesives can be used. As mentioned above, as long as the adhesive is liquid when applied and has sufficient fluidity for application, hot-melt adhesives that are not liquid at room temperature can also be used.

[0148] As described above, the first mark can also include two or more adhesive coating areas of different areas. In this case, during the adhesive coating process, the adhesive coating area in the first mark can be selected in a way that makes the amount of adhesive required for the manufactured partition structure sufficient, and the adhesive can be applied to the entire adhesive coating area.

[0149] Furthermore, as previously described, a plurality of first marks are disposed on the first main surface of the building material. Therefore, the number of first marks for applying adhesive can be selected according to the amount of adhesive required for the manufactured partition structure. For example, if it is required to apply half the amount of adhesive to the adhesive application area of ​​all the first marks, it is also possible to apply adhesive to half of the adhesive application areas of the first marks disposed on the first main surface. (2-2) Next process In the next process, on the substrate, the building face material can be arranged such that the first main surface coated with adhesive is opposite to the substrate, and the building face material is then attached to the substrate.

[0150] In the next step, as needed, fixing metal fixtures can be further nailed into the second main surface of the building material. At this time, if the second mark is provided on the second main surface of the building material, fixing metal fixtures can be nailed into the second mark.

[0151] In addition, as already explained, the second main surface is the main surface located on the opposite side of the first main surface of the building material. (2-3) Regarding other processes The manufacturing method of the partition structure in this embodiment can be any process, and may include, for example, the following cutting process and stretching process.

[0152] During the cutting process, building materials can be cut into the desired shape. Building materials have a rectangular shape when viewed from above, for example, and can therefore be cut into any shape such as a triangle or trapezoid depending on the application.

[0153] In the stretching process, the adhesive applied in the adhesive coating process can be stretched using a brush, comb, or the like. The shape of the stretched adhesive in the stretching process is not particularly limited; for example, it can be stretched in a comb-like manner across the entire first main surface, which is the coating surface, on the surface coated with adhesive for architectural materials. Since the adhesive is pre-applied to the adhesive coating area marked at the first mark in the adhesive coating process, the total amount of adhesive applied does not change even when the stretching process is performed, and a predetermined amount of adhesive can be applied to the first main surface. Furthermore, since the stretching starts from the first mark, adhesive can be applied to predetermined positions on the first main surface even when the stretching process is performed.

[0154] According to the manufacturing method of the partition structure described above, using the existing building material, a predetermined amount of adhesive can be easily applied at a predetermined position on the first main surface, which serves as the bonding surface between the building material and the substrate, while suppressing deviations caused by the installer. Therefore, for the partition structure, the bonding strength with the substrate is sufficiently improved, and the fire resistance is enhanced.

[0155] Furthermore, as described above, a plurality of the first mark is disposed on the first main surface of the building material. Therefore, when the building material is bonded to the substrate, the adhesives are disposed together on the entire first main surface of the building material, thereby improving the sound insulation of the resulting partition structure.

[0156] Furthermore, when the partition structure obtained by the manufacturing method of the partition structure of this embodiment has multiple building face materials, the unevenness of its surface can be suppressed, resulting in a smooth surface. If there is a deviation in the amount of adhesive applied between adjacent building face materials when the building face material is adhered to the substrate, the height difference between adjacent building face materials may sometimes occur depending on the amount of adhesive applied, resulting in unevenness on the surface.

[0157] In contrast, according to the aforementioned building materials, a predetermined amount of adhesive can be consistently applied to the first main surface of the building material regardless of how the installer applies it. Therefore, when multiple sheets of building materials are arranged and fixed on a substrate, the height difference between adjacent building material surfaces can be suppressed. That is, a partition structure with a smooth plane can be produced.

[0158] The above description of building facing materials, methods for manufacturing building facing materials, and methods for manufacturing partition structures illustrates the embodiments, but the present invention is not limited to the above embodiments. Various modifications and alterations can be made within the scope of the spirit of the present invention as described in the claims.

[0159] This application claims priority based on Japanese Patent Application No. 2021-150569 filed with the Japan Patent Office on September 15, 2021, and incorporates the entire contents of Japanese Patent Application No. 2021-150569 into this international application.
