Description

Manufacturing method and mold for architectural surface materials, and architectural surface materials

[0001] The present disclosure relates to a method and mold for manufacturing a building surface, and to a building surface.

[0002] When fastening architectural panels to ceiling or wall underlayments with fasteners, multiple fastening positions are marked on the wide surface of the panel at the site. However, marking the panels on the site is time-consuming, and this problem becomes even more pronounced when there are a large number of panels or when the wide surface area of ​​the panels is large. Furthermore, the fastening positions on the panels may have different pitches depending on the installation location and size, so the fastening positions must be marked taking these into consideration, which also leads to the complexity of marking on the site.

[0003] Therefore, the above-mentioned cumbersome process of marking on-site can be eliminated by marking fastening positions in advance on the wide surface of the building surface material at a factory, etc. The marking of fastening positions at a factory, etc. is generally performed by printing or inscribing the fastening positions on the wide surface of the building surface material.

[0004] However, when the architectural surface material is an interior finishing material or the like and a decorative pattern is displayed on its wide surface, printing or imprinting the above-mentioned fastening positions requires both a process for processing the decorative pattern and a process for processing the fastening pattern that determines the fastening positions of the fasteners, which increases the number of processes in the production of the architectural surface material and reduces production efficiency.

[0005] Therefore, a manufacturing method that can suppress an increase in the number of steps is desired for a manufacturing method for architectural surface materials that processes both a design pattern on a wide surface and a fastening pattern that defines the fastening position of a fastener.

[0006] Here, Patent Document 1 proposes a method for manufacturing a marked panel material, which includes the steps of preparing a panel material body having a front surface and a back surface, and providing a plurality of marks arranged at a predetermined pitch along a first direction parallel to the front surface and the back surface of the panel material body in advance on at least one of the front surface and the back surface.

[0007] Japanese Patent Application Laid-Open No. 2018-154999

[0008] The method for manufacturing marked panel materials described in Patent Document 1 is a manufacturing method in which multiple marks are attached in advance to fastening positions on the front or back of the panel body, but it does not disclose a means for solving the above-mentioned problem, i.e., a means for suppressing the increase in the number of steps when attaching both a decorative pattern and fastening positions for fasteners to the wide surface of an architectural panel material.

[0009] The present disclosure provides a method for manufacturing architectural surface materials that can suppress an increase in the number of steps when processing both a decorative pattern and a fastening pattern that determines the fastening position of a fastener on the wide surface of the architectural surface material, a mold that can be applied to this manufacturing method, and an architectural surface material manufactured by this manufacturing method.

[0010] A method for manufacturing an architectural facing material according to one aspect of the present disclosure simultaneously processes a plurality of design patterns and a plurality of fastening patterns that define fastening positions for fasteners onto a wide surface that will become the surface of the architectural facing material.

[0011] Furthermore, a mold according to another aspect of the present disclosure is a mold that is applied when performing stamping processing on one of the wide surfaces that will become the surface of the product surface material when the original sheet of the architectural surface material is cut to a predetermined planar dimension, and is provided with a plurality of decorative pattern protrusions for processing a plurality of decorative pattern grooves on the wide surface, and a plurality of fastening pattern protrusions for processing a plurality of fastening pattern grooves that define the fastening positions of fasteners on the wide surface, on one stamping surface.

[0012] Furthermore, in another aspect of the architectural facing material of the present disclosure, a plurality of decorative grooves are provided on the wide surface that forms the surface of the architectural facing material, and a plurality of fastening grooves that define the fastening positions of fasteners are provided at a predetermined pitch on the wide surface.

[0013] According to the present disclosure, it is possible to suppress an increase in the number of steps when processing both a decorative pattern and a fastening pattern that defines the fastening position of a fastener on the wide surface of an architectural surface material.

Note that in this specification and drawings, substantially identical components may be designated by the same reference numerals to avoid redundant description.

[0016] [Mold and Method for Producing Architectural Surface Material According to an Embodiment, and Architectural Surface Material] Referring to Figures 1 to 12, an example of a mold and a method for producing an architectural surface material according to an embodiment, and an example of an architectural surface material, will be described. Here, Figure 1 illustrates an example of a mold and an example of a method for producing an architectural surface material according to an embodiment. Figure 2 is a view taken along arrow II in Figure 1, showing a plan view of an example of the stamping surface of the mold. Also, Figure 3 is an enlarged view of section III in Figure 2, showing an example of dispersedly arranged decorative pattern protrusions. Figure 4 is an enlarged view of section IV in Figure 2, showing a state in which the decorative pattern protrusions and fastening pattern protrusions are aligned. Furthermore, Figure 5 is a plan view of an example of an architectural surface material according to an embodiment. Figure 6 is an enlarged view of section VI in Figure 5, showing an example of dispersedly arranged decorative pattern grooves. Figure 7 is an enlarged view of section VII in Figure 5, showing a state in which the decorative pattern grooves and fastening pattern grooves are aligned.

[0017] The mold 50 used in the method for manufacturing architectural surface materials is a mold used when processing decorative pattern grooves and fastening pattern grooves on one wide surface 11, which becomes the surface of the product surface material 10 obtained by cutting the original sheet of the architectural surface material to a predetermined planar dimension, by pressing the pressing surface 51 in the X direction using pressing processing.

[0018] Examples of product facing materials 10 to which the pressing process can be applied include gypsum board, gypsum board, calcium silicate board, particle board, hardboard, plywood, structural plywood, etc., but the product facing material 10 in the illustrated example is gypsum board. Furthermore, gypsum board includes not only general gypsum board, but also reinforced gypsum board, ordinary hard gypsum board, sheathing hard gypsum board, moisture-absorbing and desorbing reinforced gypsum board, moisture-absorbing and desorbing ordinary gypsum board, moisture-absorbing and desorbing hard gypsum board, glass fiber nonwoven fabric-reinforced gypsum board, glass mat gypsum board, etc.

[0019] The gypsum board 10 is a board in which both broad sides of a rectangular gypsum core material in a plan view are covered with gypsum board base paper, and the plan view dimensions t1 × t2 are set to 910 mm × 455 mm, 910 mm × 910 mm, 1000 mm × 1000 mm, 1000 mm × 500 mm, etc. The thickness of the gypsum board 10 is, for example, 9.5 mm or 12.5 mm. This gypsum board 10 is formed, for example, by cutting a base plate (not shown) having plan dimensions of 1854 mm × 945 mm to the desired plan view dimensions.

[0020] As shown in FIG. 2, a large number of decorative pattern protrusions 60 are provided in a dispersed manner on the pressing surface 51 of the mold 50 .

[0021] As shown in Figure 3, the decorative pattern of the numerous decorative pattern protrusions 60 presents a travertine pattern. That is, numerous decorative pattern grooves 20 presenting a travertine pattern are carved in a dispersed manner on the wide surface 11 of the gypsum board 10 that has been subjected to the pressing process using a mold 50 having the pressing surface 51 shown in the figure, as shown in Figure 5. The travertine pattern may also be called a worm-eaten pattern.

[0022] Returning to Figure 2, the stamping surface 51 of the mold 50 has a first side 52 that runs along a first direction (the horizontal direction in Figure 2) of the rectangle in a plan view, and a second side 53 that runs along a second direction (the vertical direction in Figure 2), and a plurality of fastening handle protrusions 70 are provided at a predetermined first pitch t3 on a straight line that runs along the first sides 52 on the sides of one pair of the first sides 52.

[0023] Furthermore, on the pressing surface 51, a plurality of fastening handle projections 70 are provided at a predetermined second pitch t7 on a straight line parallel to the first side 52 in the central region 55.

[0024] As shown in Figure 5, the fastening handle protrusions 70 are protrusions for carving fastening handle grooves 30 on the wide surface 11 of the architectural surface material 40 to define the fastening positions of fasteners. The architectural surface material 40 is fastened to a ceiling substrate or a wall substrate (not shown) with a plurality of fasteners (not shown). These fasteners include screws, nails, staples, etc.

[0025] 2, the first pitch t3 is set to, for example, 150 mm or less, and the second pitch t7 is set to, for example, 200 mm or less. The fastening interval of the fasteners varies depending on whether they are used to fasten architectural facings that form ceilings or walls, and whether the architectural facings are single- or multiple-ply, but is preferably set to a minimum of 50 mm and a maximum of 606 mm.

[0026] 2, the length t4 from the second side 53 to the first fastening handle projection 70 can be set to, for example, 15 mm, and similarly, the length t6 from the first side 52 to the fastening handle projection 70 can also be set to, for example, 15 mm. In the illustrated example, the multiple fastening handle projections 70 in the central region 55 are set at a distance t5 from the first side 52 that is half the width t2 of the second side 53.

[0027] As shown in Fig. 4, the fastening handle protrusions 70 are circular (including elliptical) protrusions in a plan view, and the decorative handle protrusions 60 are protrusions that simulate a travertine pattern. Therefore, the fastening handle grooves 30 formed by the fastening handle protrusions 70 being engraved into the wide surface 11 of the architectural surface material 40 are circular grooves in a plan view, as shown in Figs. 5 and 7.

[0028] In the illustrated example, the decorative pattern protrusions 60 are arranged side by side of the fastening handle protrusions 70, which are circular in plan view. As shown in Figures 2 and 4, a decorative pattern protrusion 60 is arranged side by side of each fastening handle protrusion 70 provided on the stamping surface 51, and a protrusion unit 75 is formed by the decorative pattern protrusions 60 and the fastening handle protrusions 70 that are arranged side by side.

[0029] The decorative grooves 20 formed by carving the decorative protrusions 60 shown in the illustration into the wide surface 11 of the architectural surface material 40 are grooves that mimic a travertine pattern, as shown in FIGS.

[0030] In this way, the stamping surface 51 of the mold 50 shown in Figure 2 has, on one stamping surface 51, a plurality of decorative pattern protrusions 60 for processing a plurality of decorative pattern grooves 20 on the wide surface 11 of the architectural surface material 40, and a plurality of fastening pattern protrusions 70 for processing a plurality of fastening pattern grooves 30 that determine the fastening positions of fasteners on the wide surface 11.

[0031] Therefore, when the mold 50 is used to perform stamping on the wide surface 11 of the gypsum board 10 once, a plurality of design grooves 20 and a plurality of fastening grooves 30 are simultaneously machined on the wide surface 11 of the gypsum board 10. Therefore, compared to a manufacturing method for architectural surface materials in which the design grooves 20 and the fastening grooves 30 are machined separately, the mold 50 can suppress an increase in the number of steps, contributing to a manufacturing method for architectural surface materials with high manufacturing efficiency.

[0032] Next, an example of a method for manufacturing an architectural surface material using a mold 50 will be outlined. First, to manufacture the architectural surface material 40 shown in Fig. 5, a raw sheet of gypsum board (not shown) is cut to predetermined planar dimensions to manufacture a product surface material 10. This product surface material 10 is rectangular in plan view, and its planar dimensions are, as already described, 910 mm x 455 mm, 910 mm x 910 mm, etc. (this is the cutting process).

[0033] Next, a mold 50 is applied to one of the wide surfaces 11, which will become the surface of the product surface material 10, to perform stamping processing, thereby simultaneously processing multiple decorative pattern grooves 20 (an example of a decorative pattern) and multiple fastening pattern grooves 30 (an example of a fastening pattern) (this is the stamping process).

[0034] Next, the wide surface 11, which will become the surface of the product facing 10 having the multiple design grooves 20 and multiple fastening grooves 30 processed therein, is painted and dried to complete the surface finish, producing the architectural facing 40 shown in Figure 5. A roll coater or the like is used for painting, and a dryer or the like is used for drying (these are the painting steps).

[0035] This painting process colors the wide surface 11 of the architectural facing 40, for example, white or ivory, but leaves the decorative pattern grooves 20 and fastening pattern grooves 30 uncolored, exposing the gray base paper (the base paper pressed toward the back side by the decorative pattern protrusions 60 and fastening pattern protrusions 70 of the mold 50) of the gypsum board 10. Therefore, the contrast between the decorative pattern grooves 20 and fastening pattern grooves 30 and the colored wide surface 11 creates a unique appearance design.

[0036] Furthermore, following the painting step, a chamfering step may be carried out in which the four peripheries of the architectural facing are chamfered.

[0037] By providing the protrusion units 75 on the stamping surface 51, groove units 35 consisting of fastening grooves 30 and decorative grooves 20 on either side thereof are formed at fastening positions on the wide surface 11 of the architectural surface material 40, as shown in Fig. 5, and a plurality of groove units 35 are regularly arranged at a first pitch t1 and a second pitch t2. Furthermore, a large number of decorative grooves 20 presenting a travertine pattern are dispersed throughout the entire wide surface 11, as shown in Figs. 5 and 6.

[0038] The fastening handle grooves 30 and the decorative handle grooves 20 on the sides thereof form one groove unit 35, so that a worker can find each fastening handle groove 30 more easily than when the fastening handle grooves 30, which are circular in plan view, are provided independently.

[0039] Furthermore, since the decorative pattern grooves 20 forming the groove units 35 are similar to the dispersed travertine pattern decorative pattern grooves 20, the decorative pattern grooves 20 forming the groove units 35 do not impair the external design of the architectural surface material 40. Note that while a fastening pattern groove 30 with a design different from the dispersed travertine pattern decorative pattern grooves 20 is easier to find when fastening, it may impair the sense of unity in the design of the architectural surface material 40, so it is best to set the pattern of the fastening pattern groove 30 taking both factors into consideration.

[0040] 7, the planar dimensions of the fastening groove 30, which is circular in plan view, are set to be equal to or smaller than the size of the fastener head 18 shown by the solid line, and in the illustrated example, the planar dimensions of the fastening groove 30 are set to be smaller than the size of the fastener head 18. Therefore, when the fastener 18 is driven into the fastening groove 30, the fastening groove 30 is covered by the fastener head 18, making it difficult to see the fastening groove 30 from the outside. This prevents the fastening groove 30 from being visible from the outside, which would disrupt the unity of the design of the architectural surface material 40 and reduce the deterioration of the appearance design of the finished surface.

[0041] According to the illustrated method for producing an architectural facing, a mold 50 is applied to the wide surface 11 of the gypsum board 10 to perform stamping, thereby simultaneously processing a plurality of decorative grooves 20 and a plurality of fastening grooves 30 on the wide surface 11. Therefore, compared to a method for producing an architectural facing in which the decorative grooves 20 and the fastening grooves 30 are processed separately, an increase in the number of steps can be suppressed, resulting in a method for producing an architectural facing with high production efficiency.

[0042] The architectural surface material 40 has a plurality of travertine pattern design grooves 20 dispersed on the wide surface 11, and further has a plurality of fastening grooves 30 provided at a predetermined pitch. This is a product in which a plurality of fastening grooves 30 are provided on Gyptone (registered trademark) manufactured by Yoshino Gypsum Co., Ltd.

[0043] Here, Fig. 8 shows other examples of fastening handles for the fastening handle grooves. The examples shown in Fig. 8(a) to (g) are, in order, a cross-shaped fastening handle groove 30A, an X-shaped fastening handle groove 30B, a triangle (an example of a polygon) fastening handle groove 30C, an asterisk (an example of a special symbol) fastening handle groove 30D, an exclamation mark (another example of a special symbol) fastening handle groove 30E, a question mark (another example of a special symbol) fastening handle groove 30F, and a star-shaped fastening handle groove 30G (another example of a special symbol).

[0044] By providing fastening handle protrusions of complementary shapes to these fastening handle grooves on the pressing surface of the mold, various fastening handle grooves can be machined into the wide surface 11 of the gypsum board 10. Note that, as shown in Figure 5, a single fastening handle groove may be provided on the wide surface 11, or multiple types of fastening handle grooves may be provided on the wide surface 11. Furthermore, fastening handle grooves of various shapes other than those shown in the figures may also be used.

[0045] The above has described a method for producing an architectural surface material in which a mold 50 is used to simultaneously process multiple design pattern grooves 20 and fastening pattern grooves 30 on the wide surface 11 of a gypsum board 10.However, as another example of a method for producing an architectural surface material according to an embodiment, there is also a method in which multiple design patterns and multiple fastening patterns are simultaneously processed by printing.

[0046] More specifically, there are three methods for simultaneously printing multiple design patterns and multiple fastening patterns. One of these methods involves manufacturing a gypsum board using gypsum board base paper on which multiple design patterns and multiple fastening patterns have been printed, and then cutting the gypsum board to predetermined product dimensions. Another method involves simultaneously printing (printing) a design pattern (another example of a design pattern) and a fastening pattern (another example of a fastening pattern) onto the board surface using a transfer roll or the like during the manufacturing of the gypsum board (printing process). Yet another method involves laminating a laminate paper on which multiple design patterns and multiple fastening patterns have been printed in advance onto a base plate for a building surface material, or onto a product surface material obtained by cutting a base plate to predetermined planar dimensions, or simultaneously printing (printing) a design pattern (another example of a design pattern) and a fastening pattern (another example of a fastening pattern) onto a base plate for a building surface material using a transfer roll or the like (printing process).

[0047] In this way, even if the display (mark) has both a design pattern and a fastening pattern printed on it, by printing both simultaneously on the original plate of the architectural surface material or on the wide surface of the product surface material, the number of processes can be reduced, resulting in a method of manufacturing architectural surface materials with high production efficiency.

[0048] Next, another example of the architectural surface material will be described with reference to Figures 9 and 10. Here, Figure 9 is a plan view of another example of the architectural surface material according to the embodiment, and Figure 10 is an enlarged view of the X portion of Figure 9, which is an enlarged view of another example of the dispersedly arranged decorative grooves.

[0049] The architectural surface material 40A differs from the architectural surface material 40 in that it has a plurality of marble-patterned design grooves 20A instead of the plurality of travertine-patterned design grooves 20, and further has a star-shaped fastening groove 30G, which is a special symbol. Here, the fastening groove may have a shape other than the fastening groove 30G shown in the illustration.

[0050] The architectural surface material 40A has a plurality of marble-patterned design grooves 20A dispersed on the wide surface 11, and further has a plurality of fastening grooves 30G arranged at predetermined pitches t3 and t7. This is a product in which Marbletone (registered trademark) manufactured by Yoshino Gypsum Co., Ltd. is provided with a plurality of fastening grooves 30G.

[0051] Next, still another example of the architectural surface material will be described with reference to Fig. 11. Here, Fig. 11 is a plan view of still another example of the architectural surface material according to the embodiment.

[0052] The architectural surface material 40B differs from the architectural surface material 40, 40A in that it has a star-shaped design groove 20B (an example of a design) instead of the multiple travertine- or marble-patterned design grooves 20, 20A, and further has a triangular fastening groove 30C that is different from the star-shaped fastening grooves 30, 30G. The fastening groove may have a shape other than the fastening groove 30C shown in the illustration.

[0053] The architectural surface material 40B has a plurality of star-shaped design grooves 20B dispersed on the wide surface 11, and further has a plurality of fastening grooves 30C arranged at a predetermined pitch. This is a product in which a plurality of fastening grooves 30C are provided on Stellato (registered trademark) manufactured by Yoshino Gypsum Co., Ltd.

[0054] Next, still another example of a building surface material will be described with reference to Fig. 12. Here, Fig. 12 is a perspective view of a portion of yet another example of a building surface material according to an embodiment.

[0055] The architectural facing 40C differs from the architectural facings 40, 40A, and 40B in that the multiple decorative pattern grooves 20C are through-holes instead of grooves extending partway through the thickness of the gypsum board 10. Note that while the illustrated example has cross-shaped fastening pattern grooves 30A at a predetermined pitch, the fastening pattern grooves may have shapes other than the fastening pattern grooves 30A shown in the illustration.

[0056] The through holes 20C in the illustrated example are regularly arranged (aligned at a plurality of lattice points) at a predetermined pitch t8 in both the vertical and horizontal directions on the wide surface 11. Here, the pitch t8 can be set to, for example, about 22 mm.

[0057] The architectural surface material 40C having a plurality of through holes 20C forms a perforated sound-absorbing surface material, and the plurality of through holes 20C become decorative grooves that have both sound-absorbing and decorative functions. In this way, the architectural surface material 40C having a plurality of through holes 20C arranged in a regular pattern on the wide surface 11 and a plurality of fastening grooves 30A provided at a predetermined pitch is a product in which a plurality of fastening grooves 30A are provided in Tigertone (registered trademark) manufactured by Yoshino Gypsum Co., Ltd.

[0058] Here, in the manufacturing method for simultaneously machining multiple through holes 20C and multiple fastening handle grooves 30A into the wide surface 11, a mold is applied that has multiple decorative handle protrusions and multiple fastening handle protrusions of different heights (protrusion lengths) on the stamping surface.

[0059] It should be noted that other embodiments may be possible in which other components are combined with the configurations described in the above embodiments, and the present disclosure is not limited to the configurations shown here. In this regard, modifications are possible within the scope of the present disclosure, and can be appropriately determined depending on the application form.
