Description

Technical Field

[0001] This invention relates to a method for manufacturing building facing material, a mold, and the building facing material itself. Background Technology

[0002] When using fasteners to secure building facade materials to ceiling or wall base materials, the width of the facade material is marked at multiple fixed locations on-site using a layout method. However, this on-site marking of the facade material is tedious, and this problem becomes even more pronounced when there are many facade materials or when the width of the facade material is large. Furthermore, since the spacing between the multiple fixed locations of the facade material sometimes varies depending on its location or size, these factors must be considered when marking the fixed locations, further complicating the on-site marking process.

[0003] Therefore, by pre-attaching fixed positions to the wide surface of the building material in a factory or similar location, the complexity of marking on-site can be eliminated. The attachment of fixed positions in a factory or similar location is generally done by printing the fixed positions or marking the characters on the wide surface of the building material.

[0004] However, when building materials are used as interior decoration materials and have designed patterns on their wide surface, printing or lettering is required on the aforementioned fixed positions. This requires both the processing steps for designing the patterns and the processing steps for fixing the patterns to the fixed positions of the fasteners. As a result, the number of steps in the production of building materials increases and the production efficiency decreases.

[0005] Therefore, regarding the manufacturing method of building materials for fixing patterns on both sides of a wide-format surface and a fixed pattern for specifying the fixing positions of fasteners, a manufacturing method that can suppress the increase in the number of processes is desired.

[0006] Here, Patent Document 1 discloses a method for manufacturing a marked face material. The method for manufacturing the marked face material includes the following steps: a step of preparing a face material body having a surface and a back surface; and a step of pre-attaching a plurality of marks arranged at a given interval along a first direction parallel to the surface and the back surface of the face material body.

[0007] <Prior art documents> <Patent Documents> Patent Document 1: Japanese Patent Application Publication No. 2018-154999 Summary of the Invention <Problem to be solved by this invention> The manufacturing method of the marked face material described in Patent Document 1 is a method of pre-attaching multiple marks to the fastener fixing positions on the surface or back of the face material body. However, it does not disclose a solution to the above-mentioned problem, namely, a means to suppress the increase in the number of processes when attaching design patterns and fastener fixing positions on the wide surface of the building face material.

[0008] The present invention provides a method for manufacturing building materials that can suppress the increase in the number of steps when processing design patterns and fixing patterns at fixed positions of fasteners on a wide surface of building materials, a mold used in the manufacturing method, and building materials manufactured using the manufacturing method.

[0009] <Methods for solving problems> One aspect of the present invention relates to a method for manufacturing building materials, which simultaneously processes multiple design patterns and multiple fixing patterns that specify the fixing positions of fasteners on a wide surface that becomes a building material.

[0010] Furthermore, another aspect of the invention relates to a mold used in pressing a wide surface of a product material obtained by cutting a raw board of building material into a given planar dimension. The mold has multiple pattern protrusions on one pressing surface for machining multiple pattern grooves on the wide surface, and multiple pattern protrusions for machining multiple pattern grooves on the wide surface to fix the fixed position of a fastener.

[0011] Furthermore, in another aspect of the present invention, the building material has multiple patterned grooves on a wide surface area of ​​the surface that serves as the building material. Multiple fixing grooves that define the fixing positions of fasteners are set at given intervals in the wide surface.

[0012] <The Effects of the Invention> According to the present invention, it is possible to suppress the increase in the number of steps when processing the design pattern and the fixing pattern for specifying the fixing position of the fastener on the wide surface of the building material.

[0025] Hereinafter, the manufacturing method and mold of the building surface material involved in the embodiments, as well as the building surface material itself, will be described with reference to the accompanying drawings. Furthermore, in this specification and the accompanying drawings, substantially identical components are sometimes omitted by using the same reference numerals, thus avoiding repetitive descriptions.

[0026] [The method for manufacturing the mold and building surface material involved in the embodiments, and the building surface material] Reference Figures 1 to 12 The method for manufacturing the mold and building surface material involved in the embodiments, as well as an example of the building surface material, will be described here. Figure 1These figures illustrate an example of the mold involved in the embodiment and an example of the method for manufacturing building materials involved in the embodiment. Figure 2 yes Figure 1 The arrow view in direction II is a top view of an example of the pressing surface of the mold. Furthermore, Figure 3 yes Figure 2 The enlarged view of Part III is an example of a dispersed arrangement of raised design patterns. Figure 4 yes Figure 2 The enlarged view of section IV is a top view showing the arrangement of the designed pattern protrusions and the fixed pattern protrusions. Furthermore, Figure 5 This is a top view of an example of the building facing material involved in the implementation method. Figure 6 yes Figure 5 The enlarged view of the VI section is an example of a dispersed design pattern groove. Figure 7 yes Figure 5 The enlarged view of section VII is a top view showing the design of the patterned grooves and the state of the fixed patterned groove arrangement.

[0027] The mold 50 used in the manufacturing method of building face material is a mold used to press the pressing surface 51 of a wide surface 11 of a product face material 10 obtained by cutting the original board of building face material to a given planar size, thereby processing and designing patterned grooves on the wide surface 11 and fixing the patterned grooves.

[0028] Examples of surface materials 10 used in the molding process include gypsum board or paper-faced gypsum board, calcium silicate board, particleboard, hardboard, plywood, and structural plywood. The product surface material 10 in the example shown is paper-faced gypsum board. Furthermore, regarding paper-faced gypsum board, in addition to general paper-faced gypsum board, it also includes reinforced paper-faced gypsum board, ordinary rigid paper-faced gypsum board, sheathed rigid paper-faced gypsum board, moisture-wicking reinforced paper-faced gypsum board, moisture-wicking ordinary paper-faced gypsum board, moisture-wicking sheathed rigid paper-faced gypsum board, gypsum board containing glass fiber nonwoven fabric, and glass mat paper-faced gypsum board.

[0029] The paper-faced gypsum board 10 is a board with a rectangular gypsum core material in top view, whose two wide sides are covered by paper-faced gypsum board with base paper. The top view dimensions t1×t2 are set to 910mm×455mm, 910mm×910mm, 1000mm×1000mm, 1000mm×500mm, etc. Furthermore, the thickness of the paper-faced gypsum board 10 is, for example, 9.5mm or 12.5mm. This paper-faced gypsum board 10 is formed, for example, by cutting a base board (not shown) with a planar dimension of 1854mm×945mm to the aforementioned desired planar dimensions.

[0030] like Figure 2As shown, a number of patterned protrusions 60 are distributed on the molding surface 51 of the mold 50.

[0031] like Figure 3 As shown, the design patterns of the many raised patterns 60 present a travertine-like pattern. That is, on the wide surface 11 of the paper-faced plasterboard 10 after the molding process by the mold 50 having the molding surface 51 shown in the figure, as... Figure 5 As shown, numerous patterned grooves 20 are engraved in a dispersed manner to present a travertine-like pattern. Additionally, the travertine-like pattern can also be referred to as an insect-eaten pattern.

[0032] Return to Figure 2 On the die-cutting surface 51 of the mold 50, there is a first direction along the top view rectangle ( Figure 2 The first side 52 (horizontal) and along the second direction ( Figure 2 The second side 53 (in the longitudinal direction) has a plurality of fixed patterned protrusions 70 on the straight line along the first side 52 on the side of one of the pairs of first sides 52, at a given first spacing t3.

[0033] Furthermore, on a straight line parallel to the first side 52 in the central region 55 of the molding surface 51, a plurality of fixed pattern protrusions 70 are provided at a given second spacing t7.

[0034] Fixed pattern protrusions 70 Figure 5 The image shows protrusions in the fixing grooves 30 provided for etching fixed positions of fasteners in the wide surface 11 of the building face material 40. The building face material 40 is fixed to a ceiling base material or wall base material (not shown) using a plurality of fasteners (not shown). These fasteners include screws, nails, clips, etc.

[0035] Return to Figure 2 The first spacing t3 is set to, for example, 150mm or less, and the second spacing t7 is set to, for example, 200mm or less. Furthermore, while the fixing interval of the fasteners may vary depending on which building material is used to fix the ceiling or wall, and whether the building material is a single piece or multiple pieces, a minimum setting of 50mm and a maximum setting of 606mm are preferred.

[0036] exist Figure 2 In this example, the length t4 from the second side 53 to the initial fixed pattern protrusion 70 can be set to, for example, 15 mm. Similarly, the length t6 from the first side 52 to the fixed pattern protrusion 70 can also be set to, for example, 15 mm. Furthermore, in the example shown, the plurality of fixed pattern protrusions 70 located in the central region 55 are positioned at a width t5 that is half the width t2 of the second side 53 from the first side 52.

[0037] like Figure 4 As shown, the fixed pattern protrusion 70 is a circular (or elliptical) protrusion viewed from above, while the pattern protrusion 60 is a protrusion simulating a travertine-like pattern. Therefore, the fixed pattern groove 30 formed by engraving the fixed pattern protrusion 70 on the wide surface 11 of the architectural surface material 40 is as follows... Figure 5 and Figure 7 As shown, it becomes a circular groove when viewed from above.

[0038] The illustration shows, from a top view, circular fixed patterned protrusions 70, with designed patterned protrusions 60 arranged in a patterned arrangement on the side. For example... Figure 2 and Figure 4 As shown, each of the fixed pattern protrusions 70 on the molded surface 51 is provided with a design pattern protrusion 60. The design pattern protrusions 60 and the fixed pattern protrusions 70 arranged in a mutually arranged manner form a protrusion unit 75.

[0039] The design pattern grooves 20 are formed by engraving the design pattern protrusions 60 of the example drawing on the wide surface 11 of the building material 40. Figure 5 and Figure 7 As shown, it becomes a groove that simulates a travertine-like pattern.

[0040] in this way, Figure 2 The mold 50 shown has a molding surface 51 that includes: multiple patterned protrusions 60 for processing multiple patterned grooves 20 on the wide surface 11 of the building material 40; and multiple fixed patterned protrusions 70 for processing multiple fixed patterned grooves 30 on the wide surface 11 to specify the fixing position of fasteners.

[0041] Therefore, when the mold 50 is used to perform a single pressing process on the wide surface 11 of the gypsum board 10, multiple designed patterned grooves 20 and multiple fixed patterned grooves 30 are simultaneously processed on the wide surface 11 of the gypsum board 10. Therefore, compared to the method of manufacturing building materials by processing the designed patterned grooves 20 and fixed patterned grooves 30 separately, the mold 50 can suppress the increase in the number of processes, contributing to a more efficient method of manufacturing building materials.

[0042] Next, an example of a method for manufacturing architectural facing material using mold 50 will be outlined. First, in the manufacturing process... Figure 5 When the building surface material 40 is shown, the original paper-faced gypsum board (not shown) is cut to a given planar size to produce the product surface material 10. The product surface material 10 is a top-view rectangle, and its planar dimensions are 910mm×455mm, 910mm×910mm, etc., as already described (above, cutting process).

[0043] Next, a mold 50 is used to press a wide surface 11 of the surface of the product material 10 to process multiple patterned grooves 20 (an example of a patterned design) and multiple fixed patterned grooves 30 (an example of a fixed pattern) simultaneously (the above is the pressing process).

[0044] Next, a surface finishing process is performed by coating and drying the surface of the wide surface 11, which has multiple designed patterned grooves 20 and multiple fixed patterned grooves 30 processed on it, to produce a finished product. Figure 5 The building material 40 shown is applied using a roller coater, and dried using a dryer (the above refers to the coating process).

[0045] Through this coating process, the wide surface 11 of the building material 40 is colored, for example, white or ivory. However, the patterned grooves 20 and fixed patterned grooves 30 are not colored, thus exposing the gray base paper of the gypsum board 10 (the base paper pushed towards the back side by the patterned protrusions 60 and fixed patterned protrusions 70 of the mold 50). Therefore, by contrasting the patterned grooves 20 and fixed patterned grooves 30 with the colored wide surface 11, a unique aesthetic design can be achieved.

[0046] Alternatively, the beveling process for the perimeter of the building material can be carried out after the painting process.

[0047] By providing protruding units 75 on the molding surface 51, thus achieving... Figure 5 As shown, at the fastener fixing positions in the wide surface 11 of the building material 40, groove units 35 are formed, consisting of fixed patterned grooves 30 and design patterned grooves 20 located on their sides. Multiple groove units 35 are regularly arranged with a first spacing t1 and a second spacing t2. Furthermore, throughout the entire wide surface 11, as... Figure 5 and Figure 6 As shown, numerous patterned grooves 20 with a travertine-like design are dispersedly arranged.

[0048] By forming a groove unit 35 with a fixed pattern groove 30 and a design pattern groove 20 located on its side, the operator can more easily spot each fixed pattern groove 30 compared to the case where the fixed pattern groove 30 is set individually in a circular shape when viewed from above.

[0049] Furthermore, since the design pattern groove 20 forming the groove unit 35 is the same as the design pattern groove 20 of the dispersed travertine pattern, the design pattern groove 20 forming the groove unit 35 will not hinder the appearance design of the building material 40. Additionally, regarding the fixed pattern groove 30, a pattern with a different design from the dispersed travertine pattern groove 20 is easier to spot during installation; however, on the other hand, it may hinder the design unity of the building material 40. Therefore, it is advisable to consider both aspects when setting the pattern of the fixed pattern groove 30.

[0050] like Figure 7 As shown, the planar dimension of the circular fixing groove 30, viewed from above, is set to be smaller than or equal to the size of the fastener head 18, indicated by the solid line. In the example shown, the planar dimension of the fixing groove 30 is set to be smaller than the size of the fastener head 18. Therefore, when the fastener 18 is driven into the fixing groove 30, the fixing groove 30 is covered by the fastener head 18, making it difficult to see from the outside. This suppresses the reduction in the aesthetic appeal of the finished surface, which could hinder the design unity of the building material 40 due to the fixing groove 30 being visible from the outside.

[0051] According to the illustrated method for manufacturing building materials, by applying a mold 50 to the wide surface 11 of the paper-faced gypsum board 10 for pressing, multiple designed patterned grooves 20 and multiple fixed patterned grooves 30 can be simultaneously processed on the wide surface 11. Therefore, compared with the method of manufacturing building materials by processing the designed patterned grooves 20 and fixed patterned grooves 30 separately, the increase in the number of processes can be suppressed, making it a method of manufacturing building materials with high production efficiency.

[0052] In the wide surface 11, a building material 40 with multiple travertine-like patterned grooves 20 dispersedly and multiple fixed patterned grooves 30 at given intervals is a product with multiple fixed patterned grooves 30 on Gyptone (registered trademark) manufactured by Yoshino Gypsum Co., Ltd.

[0053] Here, in Figure 8 The image shows another example of a fixed pattern for a fixed pattern groove. Figure 8 The examples shown in (a) to (g) are, in order, a cross-shaped fixed pattern groove 30A, an X-shaped fixed pattern groove 30B, a triangle (an example of a polygon) fixed pattern groove 30C, an asterisk (an example of a special mark) fixed pattern groove 30D, an exclamation mark (another example of a special mark) fixed pattern groove 30E, a question mark (another example of a special mark) fixed pattern groove 30F, and a star-shaped (another example of a special mark) fixed pattern groove 30G.

[0054] By providing fixed pattern protrusions with shapes complementary to these fixed pattern grooves on the pressing surface of the mold, various types of fixed pattern grooves can be processed on the wide surface 11 of the paper-faced gypsum board 10. Furthermore, these various shapes of fixed pattern grooves can be processed as follows: Figure 5 As shown, a single fixed pattern groove can be provided on the wide surface 11, or multiple fixed pattern grooves can be provided on the wide surface 11. In addition, fixed pattern grooves of various shapes can be applied besides those shown in the figure.

[0055] The above describes a method for manufacturing building materials that uses a mold 50 to simultaneously process multiple design pattern grooves 20 and fixed pattern grooves 30 on the wide surface 11 of a paper-faced gypsum board 10. However, other examples of the method for manufacturing building materials as an embodiment include methods that simultaneously process multiple design patterns and multiple fixed patterns by printing.

[0056] More specifically, three methods can be cited as ways to simultaneously process multiple design patterns and multiple fixed patterns through printing. One method involves manufacturing gypsum board using paper pre-printed with multiple design patterns and multiple fixed patterns, and then cutting it to a given product size. Another method involves simultaneously processing (printing) the surface of the gypsum board during its manufacturing process using a transfer roller or similar device that displays both a design pattern (another example of a design pattern) and a fixed pattern (another example of a fixed pattern). Yet another method involves laminating pre-printed laminate paper with multiple design patterns and multiple fixed patterns onto a base board for building materials, or a product material whose base board has been cut to a given planar size, or simultaneously processing (printing) both a design pattern (another example of a design pattern) and a fixed pattern (another example of a fixed pattern) using a transfer roller or similar device.

[0057] In this way, even if both the design pattern and the fixed pattern are printed at the same time, the number of processes can be suppressed by printing on both the original board of the building material or the wide surface of the product material at the same time, making it a highly efficient method for producing building materials.

[0058] Next, refer to Figure 9 and Figure 10 To illustrate another example of building facing materials, here, Figure 9 This is a top view of another example of the building materials involved in the implementation method. Figure 10 yes Figure 9 The enlarged view of the X section is another example of a dispersed pattern groove design.

[0059] The difference between architectural surface material 40A and architectural surface material 40 is that it has multiple marble-like patterned grooves 20A instead of multiple travertine-like patterned grooves 20, and it has a star-shaped fixed patterned groove 30G as a special mark. Here, regarding the fixed patterned groove, forms other than the fixed patterned groove 30G in the example can also be applied.

[0060] A building material 40A having multiple marble-like patterned grooves 20A dispersedly in a wide surface 11 and multiple fixed patterned grooves 30G set at given intervals t3 and t7 is a product with multiple fixed patterned grooves 30G set on Marbletone (Japanese original: マーブルトーン) (registered trademark) manufactured by Yoshino Gypsum Co., Ltd.

[0061] Next, refer to Figure 11 This will illustrate another example of building facing materials. Here, Figure 11 This is a top view of yet another example of the building materials involved in the implementation method.

[0062] The difference between architectural cladding 40B and architectural cladding 40 and 40A is that it has a star-shaped (as shown in the example) patterned groove 20B instead of multiple travertine or marble-like patterned grooves 20 and 20A, and it has a triangular fixed patterned groove 30C, which is different from the star-shaped fixed patterned grooves 30 and 30G. Here, regarding the fixed patterned groove, forms other than the fixed patterned groove 30C shown in the example can also be applied.

[0063] A building material 40B having multiple star-shaped patterned grooves 20B dispersed in a wide surface 11 and multiple fixed patterned grooves 30C set at a given interval becomes a product with multiple fixed patterned grooves 30C set on Stellart (Japanese original: ステラート) (registered trademark) manufactured by Yoshino Gypsum Co., Ltd.

[0064] Next, refer to Figure 12 This serves as another example to illustrate the use of building facing materials. Here, Figure 12 This is a perspective view of another example of the building materials involved in the implementation method.

[0065] The difference between architectural lining material 40C and architectural lining materials 40 and 40A is that multiple patterned grooves 20C are through holes, replacing the grooves that extend to the middle of the thickness of the paper-faced gypsum board 10. Additionally, the example shown has cross-shaped fixed patterned grooves 30A at a given spacing; however, other forms besides the fixed patterned grooves 30A shown in the example can also be applied to the fixed patterned grooves.

[0066] In the example diagram, multiple through holes 20C are arranged regularly in the width 11 with a given spacing t8 (arranged as multiple grid points). Here, the spacing t8 can be set to, for example, 22 mm.

[0067] Building materials 40C with multiple through holes 20C form porous sound-absorbing materials, and the multiple through holes 20C become design grooves that have both sound absorption performance and design performance.

[0068] In this way, a building material 40C with multiple through holes 20C arranged regularly in the wide surface 11 and multiple fixed patterned grooves 30A at a given interval becomes a product with multiple fixed patterned grooves 30A on TigerTone (registered trademark) manufactured by Yoshino Gypsum Co., Ltd.

[0069] Here, in the manufacturing method of simultaneously processing multiple through holes 20C and multiple fixed pattern grooves 30A on the wide surface 11, it is applied to a mold with multiple design pattern protrusions and multiple fixed pattern protrusions of different heights (protrusion lengths) on the die surface.

[0070] Furthermore, the structures listed in the above embodiments can also be other embodiments combining other constituent elements, and the present invention is not limited to the structures shown herein. In this regard, modifications can be made without departing from the spirit of the invention, and the specific application can be appropriately determined.
