Description

[Technical Field]

[0001] The present invention relates to a grid panel jig and a method for manufacturing a grid panel. [Background technology]

[0002] Lattice panels are used in gardens, decks, terraces, parks, etc. to protect against wind and dust, and for privacy and decorative purposes. In a manufacturing method for such a lattice panel, lower layer lattice members, which are lattice bars, are placed at regular intervals at an inclination angle of approximately 45 degrees on one side of a rectangular peripheral frame. Then, upper layer lattice members are placed on the other side of the peripheral frame in the same manner, at an inclination angle of approximately 45 degrees perpendicular to the lower layer lattice members. For example, Patent Document 1 discloses a technology for improving the appearance by minimizing the exposed portions of the rivets that rivet the ends of each lattice member to the peripheral frame.

[0003] [Patent Document 1] Patent No. 5319497 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the upper and lower lattice members are manually placed on both sides of the perimeter frame, so if the first lower lattice member is placed in the wrong tilt direction, the other lattices may also be installed in the wrong direction. Specifically, the lower lattice material needs to be arranged so that it slopes upward from the right end to the left end (left-upward), but if the lower lattice material is arranged so that it slopes upward from the left end to the right end (right-upward), the appearance of a lattice panel assembled with the slope slanting left will be different from that of a lattice panel assembled with the slope slanting right.Since the appearance of such a lattice panel is different even when it is turned inside out or upside down, when multiple lattice panels are installed side by side, the slope of the lattice material of only one lattice panel will be reversed, which creates a problem of poor appearance.

[0005] The present invention has been made in consideration of the above circumstances, and its object is to provide a grid panel jig that can arrange grid materials in the correct orientation and easily and smoothly produce grid panels with the same appearance, and a method for manufacturing grid panels using the grid panel jig. [Means for solving the problem]

[0006] The invention described in claim 1 is a lattice panel jig 100 used in manufacturing a lattice panel 500, for example, as shown in Figs. 1 to 5, when a plurality of lower-layer lattice members 52 and a plurality of upper-layer lattice members 51 are crossed and connected at intersections S to form a lattice body 501, Base material 1, a plurality of protrusions 2 provided on the base material 1 and fitted into a plurality of lattice holes 504 formed by intersecting a plurality of the lower layer lattice materials 52 and a plurality of the upper layer lattice materials 51; The present invention is characterized by comprising a baffle plate 3 which is arranged between at least any pair of adjacent protrusions 2 among the plurality of protrusions 2 and which prevents the lower layer lattice material 52 from being fitted between the pair of adjacent protrusions 2.

[0007] According to the invention described in claim 1, the present invention includes a base material 1, a plurality of protrusions 2 provided on the base material 1 and fitted into a plurality of lattice holes 504 formed by intersecting a plurality of lower-layer lattice materials 52 and a plurality of upper-layer lattice materials 51, and a baffle plate 3 disposed between at least any pair of adjacent protrusions 2 among the plurality of protrusions 2 to prevent the lower-layer lattice material 52 from fitting between the adjacent pair of protrusions 2. Therefore, for example, if the lower-layer lattice material 52 is disposed on the baffle plate 3, the lower-layer lattice material 52 will float above the upper surface 1b of the base material 1, and therefore the lower-layer lattice material 52 is not disposed on the baffle plate 3. Therefore, the lower-layer lattice material 52 can be disposed on the base material 1 in the correct orientation without making a mistake in the orientation of the lower-layer lattice material 52. As a result, even when a plurality of grid panels 500 are manufactured, all grid panels 500 have the same appearance, and can be manufactured easily and smoothly. Furthermore, the protrusions 2 are fitted into the lattice holes 504 formed by the intersection of the upper-layer lattice material 51 and the lower-layer lattice material 52, so that the upper-layer lattice material 51 and the lower-layer lattice material 52, which are arranged to intersect, are held without misalignment. Therefore, the upper-layer lattice material 51 and the lower-layer lattice material 52 can be easily connected at the intersections S to form the lattice body 501.

[0008] The invention described in claim 2 is, for example, as shown in FIG. 3, in the grid panel jig 100 described in claim 1, The thickness T3 of the baffle plate 3 is equal to the thickness T1 of the plurality of lower layer lattice members 52.

[0009] According to the invention described in claim 2, the thickness T3 of the baffle plate 3 is equal to the thickness T1 of the plurality of lower-layer lattice members 52, so when the upper-layer lattice member 51 is placed on the lower-layer lattice member 52 and the baffle plate 3, the height positions of the part of the upper-layer lattice member 51 placed on the baffle plate 3 and the part of the upper-layer lattice member 51 placed on the lower-layer lattice member 52 become uniform, and the upper-layer lattice member 51 is placed horizontally. Therefore, the lower-layer lattice member 52 and the upper-layer lattice member 51 can be smoothly connected at the intersection S.

[0010] The invention described in claim 3 is, for example, as shown in Figs. 3 and 4, in the grid panel jig 100 described in claim 1, A position on the upper surface 1b of the base material 1 along one side end surface 31 of the baffle plate 3 is a starting position for placing the first lower layer lattice material 521 of the plurality of lower layer lattice materials 52.

[0011] According to the invention described in claim 3, a position on the upper surface 1b of the base material 1 along one side end surface 31 of the baffle plate 3 is set as the starting position for placing the first lower-layer lattice material 521 of the plurality of lower-layer lattice materials 52, so that the starting position can be easily grasped and the first lower-layer lattice material 521 can be smoothly placed.

[0012] The invention described in claim 4 is, for example, as shown in Figs. 3 and 4, in the grid panel jig 100 described in claim 1, The baffle plate 3 arranged between a pair of protrusions 2 is characterized in that at least one end face 32 of both end faces in a direction intersecting the space between the protrusions 2 does not protrude from one side face (e.g., the second side face 22) of the pair of protrusions 2.

[0013] According to the invention described in claim 4, the baffle plate 3 arranged between a pair of protrusions 2 has at least one end face 32 of both end faces in the direction intersecting the space between the protrusions 2, which does not protrude from one side face (second side face 22) of the pair of protrusions 2. Therefore, by arranging the lower layer lattice material 52 so that it is aligned with the one end face 32 of the baffle plate 3 and one side face (second side face 22) of the pair of protrusions 2, the positioning of the lower layer lattice material 52 can be easily carried out.

[0014] The invention described in claim 5 is, for example, as shown in Figs. 2 to 4, in the grid panel jig 100 described in claim 1, The multiple protrusions 2 are characterized in that the side surfaces (e.g., the third side surface 23 or the first side surface 21) arranged along the lower layer lattice material 52 and the upper layer lattice material 51 are arranged at an angle relative to the four sides of the base material 1 when viewed in a plane.

[0015] According to the invention described in claim 5, the multiple protrusions 2 have side surfaces (third side surface 23 or first side surface 21) arranged along the lower layer lattice material 52 and the upper layer lattice material 51, which are arranged at an angle relative to the four sides of the base material 1 when viewed in a plane, and therefore can be suitably used as a jig for lattice panels assembled in an oblique lattice pattern.

[0016] The invention described in claim 6 is, for example, as shown in FIG. 6, in the grid panel forming jig 100A described in claim 1, The multiple protrusions 2 are characterized in that the side surfaces (e.g., the third side surface 23 or the first side surface 21) arranged along the lower layer lattice material 52 and the upper layer lattice material 51 are arranged parallel to the four sides of the base material 1 in a planar view.

[0017] According to the invention described in claim 6, the multiple protrusions 2 have sides (for example, the third side 23 or the first side 21) arranged along the lower layer lattice material 52 and the upper layer lattice material 51, which are arranged parallel to the four sides of the base material 1 in a planar view, and therefore can be suitably used as a jig for a grid-like panel arranged vertically and horizontally in a grid pattern.

[0018] The invention described in claim 7 is, for example, as shown in FIG. 2, in the grid panel jig 100 described in claim 1, The base material 1 is characterized in that it is rotatable in the horizontal direction.

[0019] According to the invention described in claim 7, the base material 1 is freely rotatable horizontally, so that if there is a location where it is difficult to position the lower layer lattice material 52 and the upper layer lattice material 51, they can be easily positioned by rotating the base material 1 horizontally.

[0020] The invention described in claim 8 is a method for manufacturing a grid panel using the grid panel jig 100 described in any one of claims 1 to 7, as shown in, for example, FIGS. 1 to 5, a first step of arranging a first lower layer lattice member 521 of the plurality of lower layer lattice members 52 on the base member 1 so as to be adjacent to one side end surface 31 of the baffle plate 3; a second step of fitting and arranging the other lower layer lattice members 52 between the other plurality of protrusions 2; and a third step of crossing the plurality of upper-layer lattice members 51 on the plurality of lower-layer lattice members 52 and connecting them at intersections S to form the lattice body 501.

[0021] According to the invention described in claim 8, the method includes a first step of arranging a first lower-layer lattice member 521 of the plurality of lower-layer lattice members 52 adjacent to one side end surface 31 of the baffle 3 on the base material 1, a second step of arranging the other lower-layer lattice members 52 by fitting them between the other plurality of protruding portions 2, and a third step of crossing the plurality of upper-layer lattice members 51 over the plurality of lower-layer lattice members 52 and connecting them at intersection points S to form the lattice body 501. Therefore, by arranging the first lower-layer lattice member 521 adjacent to one side end surface 31 of the baffle 3, the first lower-layer lattice member 521 can be arranged in the correct orientation on the base material 1, and the other lower-layer lattice members 52 can also be arranged in the correct orientation by fitting them between the protruding portions 2 and arranging them sequentially. Furthermore, since the other lower-layer lattice members 52 are arranged by fitting them between the multiple protruding portions 2, the protruding portions 2 can prevent the lower-layer lattice members 52 from shifting in position. Then, by crossing the plurality of upper layer lattice members 51 over the plurality of lower layer lattice members 52 and connecting them at intersection points S, the lattice body 501 can be easily formed. As described above, even when a plurality of grid panels 500 are manufactured, all grid panels 500 having the same appearance can be manufactured easily and smoothly. [Effects of the Invention]

[0022] According to the present invention, it is possible to provide a grid panel jig that can arrange grid materials in the correct orientation and easily and smoothly produce grid panels with the same appearance, and a method for manufacturing grid panels using the grid panel jig.

[0024] Hereinafter, embodiments will be described with reference to the drawings. Features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. The drawings are provided for illustrative purposes only, and the scope of the present invention is not limited to the examples in the drawings.

[0025] [Grid panel jig] Fig. 1 is an external perspective view of a grid panel. Fig. 2 is an external perspective view of a grid panel jig. Fig. 3 is a schematic perspective view showing a main part of Fig. 2. Figs. 4 and 5 are plan views for explaining a method for manufacturing a grid panel. The lattice panel jig 100 is used in the manufacture of a lattice panel 500 when a plurality of lower-layer lattice members 52 and a plurality of upper-layer lattice members 51 are intersected and connected at intersection points S to form a lattice body 501.

[0026] The lattice panel 500 is used in gardens, decks, terraces, parks, etc. to protect against wind and dust, provide shade, privacy, decorative purposes, etc. As shown in Fig. 1, the lattice panel 500 comprises a lattice body 501 and a rectangular frame body 502. The rectangular frame body 502 is formed by assembling long frame members 503 lengthwise and crosswise in a rectangular shape.

[0027] The lattice body 501 includes a plurality of lower layer lattice members 52 and a plurality of upper layer lattice members 51 . The lower layer lattice member 52 and the upper layer lattice member 51 are long plate-like members. The longitudinal ends of the lower layer lattice member 52 and the upper layer lattice member 51 are each formed to be inclined obliquely, and are approximately trapezoidal in plan view. The lower layer lattice member 52 and the upper layer lattice member 51 each have the same thickness T1, which is also equal to the thickness T3 (see FIG. 3) of the baffle plate 3 described below. The lower layer lattice members 52 each have a different length so that a lattice structure can be formed. Similarly, the upper layer lattice members 51 each have a different length.

[0028] After arranging such a plurality of lower-layer lattice materials 52 on the base material 1 of the lattice panel jig 100 described below, a plurality of upper-layer lattice materials 51 are arranged crosswise on top of the plurality of lower-layer lattice materials 52 and connected at intersections S to form a lattice body 501. The lattice body 501 is fitted into a rectangular frame body 502 to form a lattice panel 500.

[0029] As shown in FIG. 2, the grid panel jig 100 includes a base material 1, a plurality of protrusions 2, and a baffle plate 3.

[0030] <Base material> The base material 1 is used while lying on a flat surface. The base material 1 has a substantially rectangular plate shape in a plan view. The base material 1 is not limited to a plate shape, but may also be a sheet shape. Furthermore, the shape of the base material 1 may be substantially square in a plan view, depending on the shape of the lattice panel 500. The base material 1 is preferably made of wood or resin, for example. A rectangular frame 4 is fixed to the outer peripheral edge of the base material 1. The rectangular frame 4 is made up of an upper frame member 41, a lower frame member 42, a left frame member 43, and a right frame member 44 assembled lengthwise and crosswise. The base material 1 is rotatable in the horizontal direction. A rotation mechanism that rotates the base material 1 around a rotation axis perpendicular to the bottom surface is preferably provided on the bottom surface of the base material 1. Although not shown, the rotation mechanism may be configured to include a horizontal support plate provided on the bottom surface of the base material 1, a rotation axis extending vertically downward from the support plate, and a base provided at the bottom end of the rotation axis to support the rotation axis so that it can rotate around the axis. The base material 1 equipped with such a rotation mechanism is placed in a lying position, for example, by placing the base on a flat surface such as a workbench, floor, or ground. Then, the lower layer lattice material 52 and the upper layer lattice material 51 can be placed on the base material 1 while rotating it around the rotation axis. When using a base material 1 that does not have a rotation mechanism, a workbench having a rotating top panel (rotation mechanism) may be used, or an independent rotation device (rotation mechanism) that is installed on a workbench, floor, etc. In this case, the base material 1 is placed on the rotation mechanism and arranged in a lying state. Furthermore, a plurality of protrusions 2 are fixed to the upper surface 1b of the base material 1.

[0031] <Convex part> The protrusion 2 has a rectangular plate shape. The protrusion 2 is preferably made of wood or resin, for example. Although the protrusion 2 has a square shape in plan view in Fig. 2, it is not limited to this and may have a rectangular or diamond shape in plan view, and can be modified as appropriate. The plurality of protrusions 2 are fixed at predetermined intervals on the base material 1 by a fixing material (not shown). Examples of the fixing material include screws, staples, tackers, bolts and nuts, and adhesives.

[0032] Of the four sides, the protrusion 2 has a first side 21 and a second side 22 that are parallel to the sides along the longitudinal direction of the lower layer lattice material 52, and a third side 23 and a fourth side 24 that are parallel to the sides along the longitudinal direction of the upper layer lattice material 51. 4, the multiple protrusions 2 are arranged at an angle of 45 degrees with respect to the four sides of the base material 1 in plan view. Specifically, in plan view, the angle α formed between one of the four sides of the base material 1 (for example, the upper frame member 41) and the first side surface 21 of the protrusion 2 is 45 degrees. In addition, the angle α formed between one of the four sides of the base material 41 (the upper frame member 41) and the third side surface 23 of the protrusion is 45 degrees. This allows the lattice panel jig 100 to be used as a jig for a lattice panel. The inclination angle α at which the protrusions 2 are arranged is not limited to 45 degrees and can be changed as appropriate.

[0033] The multiple protrusions 2 are arranged at predetermined intervals along the four sides of the base material 1. That is, the multiple protrusions 2 are arranged at predetermined intervals M along the longitudinal direction of the upper frame material 41, the left frame material 43, the lower frame material 42, and the right frame material 44. Between the multiple protrusions 2, one end (right end) of the lower-layer lattice material 52 is arranged so as to be inclined upward to the right relative to the other end (left end). Therefore, the interval M between adjacent protrusions 2 in the horizontal or vertical direction corresponds to the width W of the lower-layer lattice material 52. In detail, for example, in Figures 2 and 4, in the left-side convex portion 2a and the right-side convex portion 2b that are adjacent to each other in the horizontal direction, the length N of the perpendicular line that is perpendicular to the extension line of the second side surface 22a that contacts the lower lattice material 52 of the left-side convex portion 2a and the extension line of the first side surface 21b that contacts the lower lattice material 52 of the right-side convex portion 2b is approximately equal to the width W of the lower lattice material 52. Similarly, in the upper protrusion 2c and the lower protrusion 2d that are adjacent to each other in the vertical direction, the length N of a perpendicular line that is perpendicular to an extension line of the second side surface 22c that contacts the lower-layer lattice material 52 of the upper protrusion 2c and an extension line of the first side surface 21d that contacts the lower-layer lattice material 52 of the lower protrusion 2d is approximately equal to the width W of the lower-layer lattice material 52. Therefore, by arranging the lower-layer lattice material 52 between the adjacent protrusions 2, the position of the lower-layer lattice material 52 is determined.

[0034] 2 and 4, the protrusions 2 are provided along the four sides of the base material 1, but this is not limiting, and the protrusions 2 may also be provided in the center of the base material 1. In this case, the protrusions 2 are also provided in the center at the same inclination angle α as the protrusions 2 provided along the four sides. The thickness T2 of the protrusion 2 is approximately equal to the sum of the thickness T1 of one lower-layer lattice material 52 and the thickness T1 of one upper-layer lattice material 51. In other words, the thickness T2 of the protrusion 2 is approximately equal to the thickness when the upper-layer lattice material 51 is placed on the lower-layer lattice material 52.

[0035] <Baffle Plate> A baffle plate 3 is disposed between at least any pair of adjacent protrusions 2 among the plurality of protrusions 2. The baffle plate 3 prevents the lower lattice member 52 from being fitted between a pair of adjacent protrusions 2. In other words, the baffle plate 3 is provided so that the first lower-layer lattice member (first lower-layer lattice member 521) to be disposed on the base member 1 is tilted in the correct direction. In FIG. 2, a baffle plate 3 is disposed between a pair of protrusions 2 disposed at the upper left corner C1 of the base material 1.

[0036] The baffle plate 3 has a rectangular plate shape. The baffle plate 3 is preferably made of, for example, wood or resin. Although the baffle plate 3 has a substantially rectangular shape in plan view in Fig. 2, it is not limited to this shape and may have a square shape in plan view depending on the width W of the upper layer lattice material 51 and the lower layer lattice material 52. The baffle plate 3 is provided between the pair of protrusions 2 so that its longitudinal direction is perpendicular to the longitudinal direction of the lower layer lattice material 52 . The position of the baffle plate 3 is not limited to between the pair of protrusions 2 arranged in the upper left corner C1, but may be between a pair of protrusions 2 arranged in another position, as long as it is arranged perpendicular to the longitudinal direction of the lower-layer lattice material 52. Furthermore, the baffle plate 3 is not limited to being arranged in one place on the base material 1, and may be arranged in multiple places. As shown in Fig. 3, both longitudinal end faces 31, 32 of the baffle 3 are flush with the first side face 21 and the second side face 22 of the convex portion 2, respectively. Therefore, by arranging the lower layer lattice member 52 so as to be along the flush first side face 21 of the convex portion 2 and one side end face 31 of the baffle 3, or along the flush second side face 22 of the convex portion 2 and one side end face 32 of the baffle 3, the positioning of the lower layer lattice member 52 can be easily performed. Note that in Fig. 3, both longitudinal end faces 31, 32 of the baffle 3 are flush with the first side face 21 and the second side face 22 of the convex portion 2, respectively, but it is only necessary that the longitudinal end faces 31, 32 of the baffle 3 do not protrude outward from the first side face 21 and the second side face 22 of the convex portion 2. This prevents the baffle 3 from affecting the arrangement of the lower lattice member 52.

[0037] The thickness T3 of the baffle plate 3 is equal to the thickness T1 of the upper-layer lattice material 51 and the thickness T1 of the lower-layer lattice material 52. Therefore, when the lower-layer lattice material 52 is arranged on the base material 1, if the lower-layer lattice material 52 is arranged on the baffle plate 3, the lower-layer lattice material 52 will float above the upper surface 1b of the base material 1, and therefore it is possible to notice an error in the tilt direction of the lower-layer lattice material 52. Furthermore, when the lower-layer lattice material 52 is placed on the base material 1 in the correct orientation, the upper surface of the lower-layer lattice material 52 is flush with the upper surface of the baffle plate 3. Therefore, when the upper-layer lattice material 51 is placed on the upper surfaces of the lower-layer lattice material 52 and the baffle plate 3, the upper-layer lattice material 51 can be placed horizontally.

[0038] 3, a position on the upper surface 1b of the base material 1 along one side end face 31 of the baffle plate 3 is set as a start position for placing the first lower-layer lattice member 521 of the plurality of lower-layer lattice members 52. In other words, a position on both longitudinal end faces of the baffle plate 3 along one side end face 31 facing the upper left corner C1 of the base material 1 is set as the start position. It is preferable that a panel P1 labeled "Start Position" is attached to the start position. Also, to make the start position even clearer, a panel P2 labeled "1" may be attached near panel P1.

[0039] [Method of manufacturing grid panels] A method for manufacturing the lattice panel 500 using the above-described lattice panel jig 100 will now be described. The method for manufacturing the grid panel 500 includes the following first, second, and third steps.

[0040] <First step> In the first step, a first lower-layer lattice member 521 of the plurality of lower-layer lattice members 52 is placed adjacent to the baffle plate 3 on the base material 1. In detail, as shown in Fig. 4, the first lower-layer lattice member 521 is placed on the base material 1 so as to overlap with the display of the panel P1 at the start position along one side end face 31 of the baffle plate 3. As a result, the first lower-layer lattice member 521 is placed with its right end portion inclined upward to the right relative to its left end portion. Here, when arranging the first lower-layer lattice material 521, if it were arranged on the baffle plate 3, the first lower-layer lattice material 521 would float above the upper surface 1b of the base material 1, and therefore it is not arranged on the baffle plate 3. The upper surface of the first lower-layer lattice material 52 arranged on the panel P1 at the start position is at the same height as the upper surface of the baffle plate 3.

[0041] Here, the first lower-layer lattice material 521 refers to the lower-layer lattice material 52 that is the first of the multiple lower-layer lattice materials 52 to be placed on the base material 1, in other words, the lower-layer lattice material 52 that is placed at the starting position. In FIG. 4, the first lower-layer lattice material 521 is the lower-layer lattice material 52 that is the shortest of the multiple lower-layer lattice materials 52. The second lower-layer lattice material 522, which will be described later, refers to the second shortest lower-layer lattice material 52 that is placed second on the base material 1. The same applies to the third and subsequent lower-layer lattice materials, and refers to the lower-layer lattice materials 52 that are placed third and subsequent in order.

[0042] <Second process> In the second step, other lower-layer lattice materials 52 than the first lower-layer lattice material 521 are fitted between the other multiple protrusions 2. Specifically, the second lower-layer lattice material 522 is fitted between the protrusions 2 adjacent to the first lower-layer lattice material 521 in the width direction. Similarly, the third and subsequent lower-layer lattice materials are sequentially fitted between the protrusions 2 adjacent to the second lower-layer lattice material 522 in the width direction. In this manner, the lower-layer lattice materials 52 are sequentially arranged from the start position on the base material 1 toward the center (toward the X direction in FIG. 4). As a result, the multiple lower layer lattice members 52 are arranged with their right end portions inclined upward to the right relative to their left end portions. Next, adhesive is applied to the upper surfaces of the arranged lower-layer lattice members 52 at positions that will become intersection points S where the upper-layer lattice members 51 intersect.

[0043] <Third process> In the third step, a plurality of upper-layer lattice materials 51 are crossed over a plurality of lower-layer lattice materials 52 and connected at intersection points S to form a lattice body 501. In detail, as shown in Fig. 5, a plurality of upper-layer lattice materials 51 are sequentially arranged on the lower-layer lattice materials 52 in a crossing manner from a position on the upper right corner C2 side of the base material 1 toward the center (toward the Y direction in Fig. 5), and the upper-layer lattice materials 51 are fitted between adjacent protrusions 2. By fitting the upper-layer lattice material 51 in this manner, the protrusions 2 are fitted into the lattice holes 504 formed by the intersection of the upper-layer lattice material 51 and the lower-layer lattice material 52. Therefore, the upper-layer lattice material 51 and the lower-layer lattice material 52, which are arranged to intersect, are held in place without misalignment. As a result, the upper layer lattice material 51 is arranged with its left end portion inclined upward to the left relative to its right end portion. The lower layer lattice material 52 and the upper layer lattice material 51 are then connected by an adhesive applied onto the lower layer lattice material 52, thereby forming the lattice body 501.

[0044] A frame body 502 prepared in advance is fitted into the lattice body 501 formed as described above to form a lattice panel 500 (see FIG. 1).

[0045] In the above embodiment, the first lower layer lattice material 521 is the lower layer lattice material with the shortest length among the multiple lower layer lattice materials 52, but other lower layer lattice material may be used as the first lower layer lattice material depending on the starting position.

[0046] Furthermore, the order in which the multiple lower-layer lattice materials 52 are arranged in the second step and the order in which the multiple upper-layer lattice materials 51 are arranged in the third step are not limited to the order in the above embodiment and can be changed as appropriate, as long as the first lower-layer lattice material 521 is arranged at the starting position. Furthermore, although the lower layer lattice material 52 and the upper layer lattice material 51 are connected with an adhesive, this is not limiting and other connecting materials may be used, such as staples, bolts and nuts, or a combination of adhesive and staples.

[0047] In addition, although the multiple lower layer lattice members 52 and upper layer lattice members 51 are prepared in advance in different lengths to match the size of the lattice panel to be created and then arranged, this is not limiting and all lengths may be the same. In this case, after forming the lattice body 501, the lattice body 501 can be cut to match the dimensions of the rectangular frame body 502.

[0048] Although the frame body 502 in the above embodiment is rectangular, it is not limited to this and may be a frame body attached only to the left and right sides of the lattice body 501 without providing frame members above and below it. 1 is installed so that the lower layer lattice material 52 faces the outdoors and the upper layer lattice material 51 faces the building, but they may be installed upside down. Even if the upper layer lattice material 51 is installed upside down, the lower layer lattice material 52 has its left end tilted upward to the right relative to the right end, and the upper layer lattice material 51 has its left end tilted upward to the left relative to the right end, and the appearance of the lattice panel 500 remains the same.

[0049] According to this embodiment, the following excellent effects are achieved. The lattice panel jig 100 includes a base material 1, a plurality of protrusions 2 provided on the base material 1 and fitted into a plurality of lattice holes 504 formed by intersecting a plurality of lower-layer lattice materials 52 and a plurality of upper-layer lattice materials 51, and a baffle plate 3 disposed between at least any pair of adjacent protrusions 2 among the plurality of protrusions 2 to prevent the lower-layer lattice material 52 from fitting between the adjacent pair of protrusions 2. Therefore, for example, if the lower-layer lattice material 52 is placed on the baffle plate 3, the lower-layer lattice material 52 will float above the upper surface 1b of the base material 1, and therefore the lower-layer lattice material 52 is not placed on the baffle plate 3. Therefore, the lower-layer lattice material 52 can be placed on the base material 1 in the correct orientation without making a mistake in the orientation of the lower-layer lattice material 52. As a result, even when a plurality of grid panels 500 are manufactured, all grid panels 500 have the same appearance, and can be manufactured easily and smoothly. Furthermore, the protrusions 2 are fitted into the lattice holes 504 formed by the intersection of the upper-layer lattice material 51 and the lower-layer lattice material 52, so that the upper-layer lattice material 51 and the lower-layer lattice material 52, which are arranged to intersect, are held without misalignment. Therefore, the upper-layer lattice material 51 and the lower-layer lattice material 52 can be easily connected at the intersections S to form the lattice body 501.

[0050] Since the thickness T3 of the baffle plate 3 is equal to the thickness T1 of the plurality of lower-layer lattice members 52, when the upper-layer lattice member 51 is placed on the lower-layer lattice member 52 and the baffle plate 3, the height positions of the part of the upper-layer lattice member 51 placed on the baffle plate 3 and the part of the upper-layer lattice member 51 placed on the lower-layer lattice member 52 become uniform, and the upper-layer lattice member 51 is placed horizontally. Therefore, the lower-layer lattice member 52 and the upper-layer lattice member 51 can be smoothly connected at the intersection S.

[0051] A position on the upper surface 1b of the base material 1 along one side end surface 31 of the baffle plate 3 is set as a start position for arranging the first lower layer lattice material 521 of the plurality of lower layer lattice materials 52, so that the start position can be easily grasped and the first lower layer lattice material 521 can be smoothly arranged.

[0052] The baffle plate 3 arranged between a pair of protrusions 2 has at least one end face 32 of both end faces in the direction intersecting the space between the protrusions 2 that does not protrude from one side face (second side face 22) of the pair of protrusions 2. Therefore, by arranging the lower layer lattice material 52 so that it is aligned with the one end face 32 of the baffle plate 3 and one side face (second side face 22) of the pair of protrusions 2, the positioning of the lower layer lattice material 52 can be easily carried out.

[0053] The multiple protrusions 2 have sides (third side 23 or first side 21) arranged along the lower layer lattice material 52 and the upper layer lattice material 51, which are arranged at an angle relative to the four sides of the base material 1 when viewed in a plane, making them suitable for use as a jig for lattice panels assembled in an oblique lattice pattern.

[0054] The base material 1 can be rotated horizontally, so that when there is a location where it is difficult to arrange the lower layer lattice material 52 and the upper layer lattice material 51, they can be easily arranged by rotating the base material 1 horizontally.

[0055] The manufacturing method of the lattice panel 500 includes a first step of arranging a first lower-layer lattice member 521 of the plurality of lower-layer lattice members 52 adjacent to one side end surface 31 of the baffle plate 3 on the base material 1, a second step of arranging the other lower-layer lattice members 52 by fitting them between the other plurality of protruding portions 2, and a third step of crossing the plurality of upper-layer lattice members 51 over the plurality of lower-layer lattice members 52 and connecting them at intersection points S to form the lattice body 501. Therefore, by arranging the first lower-layer lattice member 521 adjacent to one side end surface 31 of the baffle plate 3, the first lower-layer lattice member 521 can be arranged in the correct orientation on the base material 1, and the other lower-layer lattice members 52 can also be arranged in the correct orientation by fitting them between the protruding portions 2. Furthermore, since the other lower-layer lattice members 52 are arranged by sequentially fitting them between the plurality of protruding portions 2, the protruding portions 2 can prevent the lower-layer lattice members 52 from shifting in position. Then, by crossing the plurality of upper layer lattice members 51 over the plurality of lower layer lattice members 52 and connecting them at intersection points S, the lattice body 501 can be easily formed. As described above, even when a plurality of grid panels 500 are manufactured, all grid panels 500 having the same appearance can be manufactured easily and smoothly.

[0056] Furthermore, in recent years, there has been a demand for the realization of a carbon-neutral society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and for the achievement of the SDGs (Sustainable Development Goals), and in the construction industry, efforts are being made to build buildings using wood, which has low carbon dioxide emissions.By using wood materials as the upper and lower lattice materials, lattice panels formed using the above-mentioned lattice panel jig can contribute to the realization of a carbon-neutral society by promoting carbon neutrality and for the achievement of the SDGs.

[0057] [Variations] It should be noted that the embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be modified as appropriate without departing from the spirit of the present invention. Modifications will be described below. The following modifications may be combined as much as possible. In each of the following modifications, elements common to the above-described embodiments will be assigned the same reference numerals, and descriptions thereof will be omitted or simplified.

[0058] FIG. 6 is a plan view showing a modified grid panel jig. In the above embodiment, the arrangement of the protrusions 2 made it suitable for use in a lattice panel, but in this modified example, the side surfaces (for example, the third side surface 23 or the first side surface 21) of the multiple protrusions 2 that are arranged along the lower layer lattice material 52 and the upper layer lattice material 51 are arranged parallel to the four sides of the base material 1 in a plan view. This makes it suitable for use as a jig for a grid-like panel that is arranged vertically and horizontally in a lattice pattern.

[0059] The plurality of protrusions 2 are arranged at predetermined intervals along the four sides of the base material 1. That is, the plurality of protrusions 2 are arranged at predetermined intervals along the upper frame material 41, the left frame material 43, the lower frame material 42, and the right frame material 44. The distance L between adjacent protrusions 2 is approximately equal to the width W of the upper-layer lattice material 51 and the lower-layer lattice material 52. Therefore, by arranging the upper-layer lattice material 51 or the lower-layer lattice material 52 between adjacent protrusions 2, the upper-layer lattice material 51 or the lower-layer lattice material 52 is positioned.

[0060] Furthermore, in the above embodiment, the baffle plate 3 is provided between the second and third protrusions 2 from the left in the upper row, but it may be provided between a pair of protrusions 2 arranged at other positions as long as it is arranged at a position between adjacent protrusions 2 that is perpendicular to the longitudinal direction of the lower-layer lattice material 52. Furthermore, the baffle plate 3 is not limited to being provided at one location on the base material 2, and may be provided at multiple locations. [Explanation of symbols]
