Description

[Technical field]

[0001] The present invention relates to a method for manufacturing a panel body to be installed on a fence or a balcony. [Background technology]

[0002] Various methods have been used to construct fences on the boundary between neighboring properties. For example, in the past, panels of unit lengths (e.g., 2m) were prefabricated in factories to make construction more efficient. Summary of the Invention [Problem to be solved by the invention]

[0003] However, the land owned by each customer varies widely, and the length of each side of the fence to be constructed also varies depending on the customer's request, so there is a demand for further improvement in usability. [Means for solving the problem]

[0004] The present invention solves this problem by providing a method for manufacturing a panel body that includes the steps of preparing a panel body having upper and lower rails and multiple vertical panel materials lined up between upper and lower ridges, determining the positions to cut the upper and lower rails, shifting the upper and lower rails from the ridges, removing the vertical panel materials from the ridges, returning the upper and lower rails to the positions of the ridges before they were shifted, cutting the upper and lower rails together with the ridges, and fitting vertical panel material end covers to the ends of the vertical panel materials so that the cut surfaces of the upper and lower rails are approximately aligned with the end surfaces of the vertical panel material end covers.

[0005] In a different embodiment, the present invention solves the problem by providing a method for manufacturing a panel body including the steps of: preparing a panel body having upper and lower rails and a plurality of vertical panel materials arranged in a row between upper and lower rails; determining positions for cutting the upper and lower rails; shifting the upper and lower rails from the rails; removing the plurality of vertical panel materials from the rails; returning the upper and lower rails to the positions of the rails before they were shifted; cutting the upper and lower rails together with the rails; using one of the removed vertical panel materials as a vertical panel material for cutting and shortening its width dimension taking into account the width dimension of the vertical panel material end cover; returning the cut and shortened vertical panel material to the rails; and fitting a vertical panel material end cover to the end of the cut and shortened vertical panel material so that the cut surfaces of the upper and lower rails and the end face of the vertical panel material end cover are approximately aligned. Effect of the Invention

[0006] Depending on the situation, panels of various widths can be manufactured on-site, making construction easier and improving usability. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The panel body 1 of the present invention is used in various places such as windows and fences. The following explanation will be given using drawings, but the drawings are created for explanatory purposes, and in order to make the explanation easier to understand, some components not necessary for the explanation may not be shown intentionally. Also, some components may be shown intentionally large or small for the explanation, and the drawings are not drawn to an accurate scale. In the following description, the same reference numerals in different drawings indicate parts having the same functions, and duplicated descriptions in each drawing will be omitted as appropriate. EXAMPLES

[0009] (Overall structure of the panel body) FIG. 1 is an explanatory diagram of a panel body 1 and its constituent members, and FIG. 1(A) is a front view of a fence F to which two panel bodies 1 are attached. The fence F is 4 m long, and in Example 1, two panel bodies 1, each 2 m long, are used, and each panel body 1 is joined at a panel body joint 18. Each panel body 1 is supported by multiple posts 4. The panel body 1 has an upper crosspiece 12 and a lower crosspiece 13. A plurality of vertical panel materials 11 are attached between the upper crosspiece 12 and the lower crosspiece 13. A gap 16 is provided between the vertical panel material 11 and the adjacent vertical panel material 11 to allow ventilation. Each vertical panel material 11 is arranged in a row between a pair of upper and lower joints 14 (not shown) to be described later, and is fixed to the joints 14.

[0010] (Vertical panel material) Fig. 1(B) is an enlarged cross-sectional view between aa in Fig. 1(A). There are two types of vertical panel materials 11 constituting the panel body 1, one of which is a middle vertical panel material 111 and the other is an end vertical panel material 112. The middle vertical panel material 111 and the end vertical panel material 112 are both extruded shapes having a hollow portion 115. The panel body 1 and the adjacent panel body 1 are joined at a panel body joint 18. At the panel body joint 18, the end vertical panel materials 112 of each panel body 1 are joined facing each other. The number and width of the vertical panel members 11 attached to the panel body 1 can be determined appropriately.

[0011] (Vertical end panel material) Fig. 1(C) is an enlarged cross-sectional view of end vertical panel material 112, and Fig. 1(E) is an enlarged cross-sectional view of panel body joint portion 18. Frame portion 117 has a hollow portion 115, and has a tapping hole 114 within hollow portion 115. Tapping hole 114 is used to fix end vertical panel material 112 to attachment 14, which will be described later. The end vertical panel material 112 has an engagement protrusion 181 and a protrusion receiving portion 182 on its visible surface. The panel body joint 18 has a joint structure in which the engagement protrusion 181 of the end vertical panel material 112 of one panel body 1 engages with the protrusion receiving portion 182 of the end vertical panel material 112 of the other panel body 1. The end vertical panel material 112 has a panel surface portion 116 on the visible side of one side of the hollow portion 115 (the side on which the engagement protrusion 181 is not provided).

[0012] (Middle vertical panel material) 1(D) is an enlarged cross-sectional view of the middle vertical panel material 111. Both sides of the visible surface of the hollow portion 115 of the middle vertical panel material 111 are panel surface portions 116. The middle vertical panel material 111 is wider than the end vertical panel materials 112, and has a tapping hole 114 in the hollow portion 115 formed within the frame portion 117. The tapping hole 114 is used to fix the middle vertical panel material 111 to the attachment 14 described below. (Fuzi) 2 is a vertical cross-sectional view of the panel body 1, an exploded enlarged view of the upper rail 12, and an exploded enlarged view of the lower rail 13. The upper rail 12 has an open lower part, and upper rail attachment slide grooves 121 are provided at both ends of the opened lower part in the short direction. The lower rail 13 has an open upper part, and lower rail attachment slide grooves 131 are provided at both ends of the opened upper part in the short direction. The upper and lower attachments 14 are attached to the vertical panel materials 11 (middle vertical panel materials 111 or end vertical panel materials 112) arranged in a row between them.

[0013] As shown in Fig. 1(C) or 1(D), the intermediate vertical panel material 111 or the end vertical panel material 112 has a tapping hole 114 formed in a hollow portion 115. The attachment piece 14 has mounting holes (not shown) formed at predetermined positions so that the vertical panel material 11 can be attached at a predetermined mounting interval. The tapping hole 114 of the vertical panel material 11 and the mounting hole formed in the attachment piece 14 are aligned. The attachment piece 14 and the vertical panel material 11 are integrated by fastening the tapping hole 114 of the vertical panel material 11 through the mounting hole of the attachment piece 14 with a screw 15.

[0014] The attachment 14 also has a pair of guide pieces 141 in the longitudinal direction. The guide pieces 141 of the attachment 14 integrated with the vertical panel material 11 are aligned with the upper crosspiece slide groove 121 and the lower crosspiece slide groove 131 exposed at the ends of the upper crosspiece 12 and the lower crosspiece 13. The upper crosspiece 12 and the lower crosspiece 13 are then slid relative to the attachment 14 integrated with the vertical panel material 11, and the guide pieces 141 fit into the upper crosspiece slide groove 121 and the lower crosspiece slide groove 131. As a result, the head of the screw 15 is swallowed by the upper crosspiece 12 and the lower crosspiece 13, and the fastening and fixing portion of the vertical panel material 11 is hidden. The panel body 1 is assembled in a factory, making on-site installation of the panel body 1 more efficient.

[0015] (On-site manufacturing of cut panels) When installing the panel body 1, as explained in the prior art, the shape and perimeter of the lot vary, and on-site work such as cutting and shortening the panel body 1 is required to accommodate these. If there is a limit to the length to which it can be cut, the panel body 1 cannot be cut to the desired length. As a result of cutting and shortening the panel body 1 while observing the limit, there will be places where the vertical panel material 11 does not fit, which will spoil the aesthetic appearance. Furthermore, at places where the direction of the fence F changes, such as corners of the lot, two panel bodies 1 with different orientations will not form a clean corner, and one panel body 1 will be positioned protruding from the corner, which is an inconvenience. The following embodiment is intended to eliminate as much restriction as possible on the length by which the panel body 1 can be cut and shortened, thereby improving ease of use during construction on site.

[0016] (Embodiment 1: Only the upper and lower bars and the attachments are cut) The first embodiment is a method for manufacturing a panel body 1 having a desired width by cutting and shortening only the upper and lower crosspieces (12, 13) and the joints 14, without cutting the vertical panel material 11. FIG. 3 is an explanatory diagram of (A) step 1 to (D) step 4A of the manufacturing method for the panel body 1 of embodiment 1 [an embodiment in which only the upper and lower crosspieces (12, 13) and the attachment 14 are cut]. In the following explanation, the first to seventh steps will be explained in order, but depending on the steps, they may not be explained in the order described, and the order of the steps may be changed.

[0017] [1st step] The first step shown in Figure 3(A) is to prepare at the work site a panel body 1 made in a factory, which has upper and lower rails 12 and 13 and has multiple vertical panel materials 11 arranged in a row between upper and lower brackets 14.

[0018] [Second process] The second step shown in Figure 3(B) is a step of determining the position C1 at which to cut the upper and lower crosspieces (12, 13). The dashed line in Figure 3(B) indicates the cutting position C1. The worker decides on-site where to install the fence F together with the customer. Once the location to install the fence F has been determined, the worker measures the length of one side of the fence F and determines the number of vertical panel materials 11 to be removed based on the measured length, and the position C1 at which to cut the upper and lower crosspieces (12, 13) and the joints 14. In embodiment 1, the vertical panel material 11 is not cut, and only the upper and lower crosspieces (12, 13) and the studs 14 are cut and shortened, so the cutting position C1 is determined in the gap 16 formed between the middle vertical panel materials 111. As described later, in the first embodiment, the cutting position C1 can be shifted by various means, and it is not necessary to set the cutting position C1 at the gap 16. The cutting position C1 illustrated in FIG. 3(B) is merely an example.

[0019] [3rd step] The third step shown in Figure 3(C) is a step of shifting the upper and lower crosspieces (12, 13) from the pin 14. The worker slides the upper and lower crosspieces (12, 13) in line with the cutting position C1 determined in the second step until the screws 15 fixing the unnecessary vertical panel material 11 are exposed. The pin 14 is exposed as the upper and lower crosspieces (12, 13) slide. The upper and lower crosspieces (12, 13) have an upper crosspiece pin slide groove 121 and a lower crosspiece pin slide groove 131, and slide smoothly along the guide piece 141 of the pin 14.

[0020] [4th A process] Step 4A shown in FIG. 3(D) is a step of removing the screws 15 fastening the attachments 14 and the vertical panel material 11 in order to remove the vertical panel material 11 that is no longer needed. In the embodiment, the vertical panel material 11 is fixed to the attachment 14 with a screw 15, but it is not necessary to fix it with a screw 15. Other removable means, for example, one-touch fitting using elasticity, and other suitable modified examples are also included in the present invention.

[0021] FIG. 4 is an explanatory diagram of steps (E) 4B to (G) 6 in the manufacturing method of the panel body 1 of embodiment 1 [only the upper and lower crosspieces (12, 13) and the attachment 14 are cut]. [4th B process] Step 4B shown in FIG. 4(E) is a step of removing the vertical panel material 11 from the attachment 14 after the screws 15 have been removed.

[0022] [5th ​​step] The fifth step shown in FIG. 4(F) is a step of returning the upper and lower rails (12, 13) to the position of the pin 14 before it was shifted.

[0023] [6th step] The sixth step shown in Fig. 4(G) is a step of cutting the upper and lower crosspieces (12, 13) together with the joints 14 at the position C1 for cutting the upper and lower crosspieces determined in the second step. Since there is no need to cut the vertical panel material 11, the work efficiency is greatly improved and the ease of use is improved.

[0024] [Step 7] Fig. 5 is an explanatory diagram of step (H) 7 of the manufacturing method of the panel body 1 of embodiment 1 [only the upper and lower crosspieces (12, 13) and the attachment 14 are cut]. In the 7th step shown in Fig. 5 (H), the vertical panel material end cover 3 is fitted to the end of the uncut middle vertical panel material 111. Then, the cut surfaces of the upper and lower crosspieces (12, 13) and the end surface of the vertical panel material end cover 3 are approximately aligned. The upper crosspiece end cap material 2A and the lower crosspiece end cap material 2B can be attached as necessary.

[0025] (Vertical panel end cover) Fig. 6 is an explanatory diagram of the vertical panel material end cover 3 and the upper and lower rail end cap materials (2A, 2B). Fig. 6(A) is a cross-sectional view of the vertical panel material end cover 3. The vertical panel material end cover 3 has a cover frame portion 32, and has a cover tapping hole 33 in the hollow portion of the cover frame portion 32. The vertical panel material end cover 3 also has a swallowing portion 31.

[0026] 6(B) is an explanatory diagram showing how to attach the vertical panel material end cover 3 to the uncut intermediate vertical panel material 111. The worker can attach the vertical panel material end cover 3 so that the swallowing portion 31 of the vertical panel material end cover 3 swallows the end of the panel surface portion 116 of the intermediate vertical panel material 111.

[0027] (Upper and lower end cap materials) Fig. 6(C) is a plan view of the upper rail end cap material 2A and the lower rail end cap material 2B. The upper rail end cap material 2A and the lower rail end cap material 2B are components that are provided as needed. In the embodiment, the same structural components are used for the upper rail 12 and the lower rail 13, so the structures of the upper rail end cap material 2A and the lower rail end cap material 2B are exactly the same. If the structures of the upper rail 12 and the lower rail 13 are different, the structures of the upper rail end cap material 2A and the lower rail end cap material 2B will not necessarily be the same. There are various purposes for attaching the upper rail end cap material 2A and the lower rail end cap material 2B. If the cut surfaces of the upper and lower rails (12, 13) and the vertical panel material end cover 3 are misaligned, the upper rail end cap material 2A and the lower rail end cap material 2B can be attached to align them. They may also be attached from a design perspective.

[0028] (Flexibility of cutting position) In the first embodiment, since the vertical panel material 11 is not cut, there is a restriction in determining the cutting position C1. In the second step, the worker must determine the cutting position C1 of the upper and lower rails (12, 13) taking this restriction into consideration. Fig. 7 is an explanatory diagram showing the positional relationship between the vertical panel material end cover 3 and the middle vertical panel material 111 that remains uncut. From Fig. 7(A) to Fig. 7(C), the state in which the middle vertical panel material 111 is swallowed into the vertical panel material end cover 3 is shown. The upper and lower rails (12, 13) are not shown for the purpose of explanation. The vertical panel material end cover 3 is provided with a gap that swallows a part of the middle vertical panel material 111. This gap can be used to move the position C1 where the upper and lower rails (12, 13) are cut. The presence of the vertical panel material end cover 3 does not create a sense of incongruity in terms of design.

[0029] FIG. 8 shows an example of the cutting position C1, and FIG. 8(A) is an explanatory diagram of cutting both ends of the panel body 1. When installing the fence F, the worker wants to cut the width of the cutting width 2×W. By cutting both ends of the panel body 1, the cutting width can be set to a total of 2×W, ​​which is the right end cutting width W and the left end cutting width W. In this case, the cutting can be performed at the gap 16 between the middle vertical panel material 111 and the middle vertical panel material 111, and there is no need to cut the middle vertical panel material 111, which can be handled by embodiment 1 [cutting only the upper and lower crosspieces (12, 13) and the joint 14]. However, if the cutting width of 2×W is to be performed by cutting one end of the panel body 1, it is inevitable to cut the middle vertical panel material 111. This cannot be handled by embodiment 1, which cuts only the upper and lower crosspieces (12, 13) and the joint 14. In this way, by cutting both ends, the range of application of embodiment 1 is expanded. In addition, although an embodiment has been described in which both ends of the panel body 1 are cut to an equal width W, both ends of the panel body 1 may also be cut to unequal widths, and such ingenuity can further expand the scope of application of embodiment 1.

[0030] FIG. 8(B) is an explanatory diagram of using the end vertical panel material 112. The worker removes the middle vertical panel material 111 and the end vertical panel material 112 from the joint 14, and cuts the upper and lower rails (12, 13) and the joint 14 at the cutting position C1 determined by the worker. The end vertical panel material 112 is then returned. In this way, the panel body 1 can be cut and shortened in width units of the middle vertical panel material 111 without cutting the middle vertical panel material 111. At this time, the worker can also choose not to attach the vertical panel material end cover 3, and can further adjust the cutting position C1 depending on whether or not the vertical panel material end cover 3 is attached.

[0031] FIG. 8(C) is an explanatory diagram of the use of a vertical panel material end cover 3. In this example, the worker selects to remove the end vertical panel material 112. The width dimensions of the middle vertical panel material 111 and the end vertical panel material 112 are different, and the worker can adjust the cutting position C1 by selecting which one to remove. Also, in FIG. 8(C), the vertical panel material end cover 3 is attached. As described above, the worker can choose whether or not to attach the vertical panel material end cover 3, and can adjust the cutting position C1.

[0032] In the first embodiment, since the vertical panel material 11 is not cut, there are restrictions on the position where it can be cut and shortened, but as in the above example, the cutting position C1 can be adjusted by various means, so this is not a major restriction. In this way, the first embodiment allows the panel body 1 to be cut and shortened quite freely, making it easy to use for workers who are going to install the panel body 1.

[0033] The worker can determine the cutting position C1 so that the cut surfaces of the upper and lower crosspieces (12, 13) are approximately aligned with the end surfaces of the vertical panel material end covers 3 even after the vertical panel material end covers 3 are attached. Before the vertical panel material end covers 3 are attached, the positional relationship between the cut surfaces of the upper and lower crosspieces (12, 13) and the end of the remaining vertical panel material 11 is such that the cut surfaces protrude beyond the end of the vertical panel material 11. In this embodiment, the position of the cutting position C1 is designed in such a way that even when the vertical panel material end cover 3 is attached, the vertical panel material end cover 3 does not protrude unnaturally from the cut surfaces of the upper and lower rails (12, 13), and a panel body 1 with excellent design can be manufactured.

[0034] In the conventional manufacturing method of a panel body including cutting and shrinking, when the vertical panel material end cover 3 is attached, it may protrude unnaturally from the cut surface of the upper and lower crosspieces (12, 13). To prevent this, it was necessary to attach spacers to the ends of the upper and lower crosspieces (12, 13). In the embodiment, the position of the cutting position C1 is determined taking into account the attachment allowance of the vertical panel material end cover 3, so there is no need to attach a spacer, and the cut surface of the upper and lower crosspieces (12, 13) and the end surface of the vertical panel material end cover 3 can be almost aligned, making it possible to manufacture a panel body with excellent design. In addition, the worker has more options to attach or not attach the vertical panel material end cover 3, and depending on the option, the cutting position C1 can be moved over a wide range. If the worker decides to cut the vertical panel material 11, the procedure will proceed to the following embodiment 2.

[0035] (Embodiment 2: Cut the vertical panel material and cut the upper and lower rails and joints) The second embodiment is a manufacturing method for a panel body 1 having a desired width dimension by cutting the vertical panel material 11 and trimming the upper and lower crosspieces (12, 13) and the joints 14. The second embodiment is generally the same as the first to fifth steps of the first embodiment, up to the step of returning the upper and lower rails (12, 13) to the position of the pin 14 before shifting, and the description of the first embodiment is incorporated herein. The first to fifth steps are slightly different from the first embodiment in the step of determining the position C1 for cutting the upper and lower rails (12, 13) in the second step. In the first embodiment, the vertical panel material 11 is not cut, so there is a restriction to selecting a position where the vertical panel material 11 does not need to be cut. Since the second embodiment is an embodiment in which the vertical panel material 11 is cut, the worker is not subject to the same restrictions as in the first embodiment when determining the positions C1 for cutting the upper and lower rails (12, 13).

[0036] FIG. 9 is an explanatory diagram of step 1 in FIG. 9(A) to step 4A in FIG. 9(D) of the manufacturing method for the panel body 1 of embodiment 2 (cutting the vertical panel material 11 and cutting the upper and lower rails (12, 13) and the joints 14).

[0037] [Step 1] Step 1 is the same as in embodiment 1. This is a step of preparing at the work site a panel body 1 made in a factory, which has upper and lower rails 12 and 13, and has multiple vertical panel members 11 arranged in a row between upper and lower rails 14.

[0038] [Second process] The second step shown in Fig. 9(B) is significantly different from embodiment 1. In embodiment 2, the vertical panel material 11 is cut, and the upper and lower crosspieces (12, 13) and the joints 14 are also cut, so there are almost no restrictions on determining the position C1 for cutting the upper and lower crosspieces (12, 13) and the joints 14. The worker decides on-site where to install the fence F together with the customer. Once the location for installing the fence F has been decided, the worker measures the length of one side where the fence F will be installed, and determines the number of vertical panel materials 11 to be removed and the position C1 for cutting the panel body 1 based on the measured length.

[0039] As shown in FIG. 9(B), the vertical panel material cutting and shortening position C2 of the cut-and-shortened vertical panel material 111A is not on the same straight line as the position C1 for cutting the upper and lower crosspieces (12, 13) and the studs 14. The vertical panel material cutting and shortening position C2 is located inside the panel body 1 more than the cutting position C1. The worker determines the vertical panel material cutting and shortening position C2 in anticipation of attaching the vertical panel material end cover 3 to the end of the cut-and-shortened vertical panel material 11. Finally, the worker fits the vertical panel material end cover 3 to the end of the cut-and-shortened vertical panel material 113, and roughly aligns the cut surfaces of the upper and lower crosspieces (12, 13) and the end face of the vertical panel material end cover 3. It should be noted that the worker does not need to determine the vertical panel material cutting and shortening position C2 at the time of the second step, but can determine the vertical panel material 111A for cutting and shortening in the seventh step of Fig. 10(H) just before the cutting and shortening step, taking into consideration the width dimension of the vertical panel material end cover 3. In Fig. 9(B), for the sake of explanation, the vertical panel material cutting and shortening position C2 is shown during the second step.

[0040] As shown in Figure 9 (B), the cutting position C2 of the vertical panel material 111A for cutting is inside the position C1 at which the upper and lower crosspieces (12, 13) and the joint 14 are cut, leaving the cutting position C1 in a protruding state. Because the attachment allowance for the vertical panel material end cover 3 is taken into consideration, the vertical panel material end cover 3 can be fitted under the protruding joint 14 and fastened without using a spacer. However, in the conventional technology, the vertical panel material cutting and shortening position C2 of the vertical panel material 111A for cutting and shortening is in the same straight line as the position C1 where the upper and lower crosspieces (12, 13) and the joint 14 are cut. In other words, the cut surfaces of the cut and shortened vertical panel material 113, the upper and lower crosspieces (12, 13) and the joint 14 are flush with each other. If the vertical panel material end cover 3 is attached in this state, the vertical panel material end cover 3 will protrude from the cut surface of the joint 14 and will not be able to be fastened. Therefore, the worker must attach spacers to the cut upper and lower crosspieces (12, 13) and the joint 14 and fasten the vertical panel material end cover 3. In the second embodiment, the vertical panel material end cover 3 is cut while taking into consideration the attachment allowance, so there is no need to use spacers, improving work efficiency and ease of use.

[0041] The worker does not need to select the vertical panel material 111A to be cut and shrunk from among the vertical panel materials 11 to be removed in the second step, but may select it before the step of cutting and shrunk the vertical panel material 11 in the seventh step. In FIG. 9(B), the vertical panel material 111A to be cut and shrunk is selected in the second step for the sake of explanation. In the embodiment, all the middle vertical panel materials 111 have the same shape, so any of the middle vertical panel materials 111 to be removed may be selected as the vertical panel material 111A to be cut and shrunk. The vertical panel material 111A to be cut and shrunk does not need to be the middle vertical panel material 111, and an end vertical panel material 112 may be selected.

[0042] As described above in the section (Flexibility of cutting position), the cutting position C1 can be moved by various means, as in embodiment 1. The worker can decide the cutting position C1 by taking these means into consideration.

[0043] [3rd step] The third step shown in Fig. 9(C) is the same as in the first embodiment, and is a step of shifting the upper and lower crosspieces (12, 13) from the joint 14. The worker shifts (slides) the upper and lower crosspieces (12, 13) in accordance with the cutting position C1 determined in the second step until the screws 15 fixing the unnecessary vertical panel material 11 are exposed, thereby exposing the top surface of the joint 14.

[0044] [4th A process] Step 4A shown in Figure 9 (D) is the same as in embodiment 1, and is a step of removing the screws 15 that fasten the attachment 14 to the vertical panel material 11 in order to remove the vertical panel material 11 that is no longer needed. In the embodiment, the vertical panel material 11 is fixed to the mounting 14 by a screw 15, but it is not necessarily required to be fixed by a screw 15. Other removable means are also included in the present invention.

[0045] [4th step] FIG. 10(E) is an explanatory diagram of step 4B to step (H) is a diagram of step 7. 10(E), which is the same as the first embodiment, is a step of removing the vertical panel material 11 from which the screws 15 have been removed, from the attachments 14. At this time, the multiple vertical panel materials 11 are removed from the attachments 14.

[0046] [5th ​​step] 10(F), which is generally the same as in embodiment 1, is a step of returning the upper and lower rails (12, 13) to the position of the joint 14 before they were shifted. The difference from embodiment 1 is that the vertical panel material 111A for cutting and shortening is left, and the other vertical panel materials 11 are removed. Between the completion of step 4B and the next step 6, the worker leaves one of the removed vertical panel materials 11 to be cut as the vertical panel material 111A for cutting, and removes the other removed vertical panel materials 11.

[0047] [6th step] The sixth step in FIG. 10(G) is a step of cutting the upper and lower crosspieces (12, 13) together with the pins 14, similar to the first embodiment.

[0048] [Step 7] The seventh step in Fig. 10(H) is a step of cutting and shortening the vertical panel material 111A to be cut and shortened, taking into consideration the width dimension of the vertical panel material end cover 3. This step may be determined simultaneously with the step of determining the positions for cutting the upper and lower rails in the second step, and the order of steps does not matter as long as it is performed before cutting and shortening. At this time, the cut is performed so that tapping holes 114 remain in the cut and shrunk vertical panel material 113 .

[0049] [8th step] The eighth step in Figure 11 (I) is a step of returning the cut and shrunk vertical panel material 113 to the joint 14. The upper and lower crosspieces (12, 13) are again slid relative to the joint 14. The cut and shrunk vertical panel material 113 is returned to the joint 14 and fastened with screws 15.

[0050] [9th step] The ninth step in FIG. 11(J) is a step of preparing a vertical panel material end cover 3, fitting the cut and shrunk vertical panel material 113 into the joint 14, and fastening with screws 15.

[0051] [Step 10] In the tenth step of FIG. 11(K), the upper and lower rails (12, 13) are slid together so that the cut surfaces of the upper and lower rails (12, 13) and the end surfaces of the vertical panel end cover 3 are substantially aligned.

[0052] As explained above in the section (Flexibility of cutting position), the position for cutting the upper and lower rails (12, 13) can be adjusted with some ingenuity, and this is also effective in embodiment 2. In embodiment 2, since the vertical panel material 11 is cut, the position for cutting the upper and lower rails can be freely determined, and the cut surfaces of the upper and lower rails (12, 13) and the vertical panel material end cover 3 can be approximately aligned.

[0053] (Installation of vertical panel end covers) Figure 12 is an explanatory diagram of the vertical panel material end cover 3. Figure 12(A) is an explanatory diagram of attaching the vertical panel material end cover 3 to an intermediate vertical panel material 111 cut at the panel surface portion 116. The panel surface portion 116 on the right side of the frame portion 117 of the intermediate vertical panel material 111 in the figure has been cut and shortened. The cut surface of the cut panel surface portion 116 is swallowed up by the vertical panel material end cover 3 and the cut surface is hidden.

[0054] 12(B) is an explanatory diagram showing how the frame portion 117 of the cut intermediate vertical panel material 111 is swallowed into the swallowing portion 31 of the vertical panel material end cover 3. The panel surface portion 116 of the intermediate vertical panel material 111 is cut even shorter than in FIG. 12(A). The cut panel surface portion 116 is swallowed into the swallowing portion 31 of the vertical panel material end cover 3 together with the frame portion 117 of the intermediate vertical panel material 111. The width dimension of the swallowing portion 31 of the vertical panel material end cover 3 is set to a dimension that allows it to swallow the frame portions 117 of the intermediate vertical panel material 111 and the end vertical panel material 112.

[0055] 12(C) is an explanatory diagram of attaching a vertical panel material end cover 3 to an intermediate vertical panel material 111 cut at a frame portion 117 of the intermediate vertical panel material 111. The tapping hole 114 of the intermediate vertical panel material 111 is necessary for fastening the intermediate vertical panel material 111 cut and shortened to the joint 14. The worker can cut the intermediate vertical panel material 111 up to just before the tapping hole 114. The joint 14 has holes drilled therein for driving screws 15 into the tapping hole 114 of the cut intermediate vertical panel material 111 and into the cover tapping hole 33 of the vertical panel material end cover 3. Then, the worker fixes the cut intermediate vertical panel material 111 and the vertical panel material end cover 3 to the joints 14 with screws 15. The worker slides the upper rail 12 and the lower rail 13 relative to the joints 14, completing the manufacture of the cut and shrunk panel body 1.

[0056] As described above, the manufacturing methods of the panel body 1 of the first and second embodiments substantially eliminate restrictions on cutting and shortening the panel body 1, allowing the worker to cut and shorten the panel body 1 to any width.

[0057] (Summary of Effects of the Examples) When constructing the fence F, if the panel body 1 was merely cut and shortened, this would have been done conventionally, but the vertical panel material 11 was not cut, and the dimensions of the cut and shortening were always limited. In the embodiment, it is possible to choose whether or not to fit the vertical panel material end cover 3, which creates more flexibility in the limitations on the dimensions of the cut and shortening. In addition, the allowance for the vertical panel material 11 to be swallowed by the vertical panel material end cover 3 can also be adjusted, which further creates more flexibility in the limitations on the dimensions of the cut and shortening. In the second embodiment, by cutting the vertical panel material 11, it is possible to create more leeway in terms of the restrictions on the dimensions that can be cut and reduced. If the vertical panel material 11 and the upper and lower crosspieces (12, 13) are cut along the same cutting line, when the vertical panel material end cover 3 is fitted to the end of the cut vertical panel material 11, the vertical panel material end cover 3 will protrude from the cut surface of the upper and lower crosspieces (12, 13) and the joint 14, resulting in a poor design. Moreover, because the vertical panel material end cover 3 protrudes from the end of the joint 14, it is not possible to fasten the vertical panel material end cover 3 to the joint 14, and the worker will need to prepare a separate fastening member such as a spacer (not shown) to replace the joint 14 on the cut surface of the upper and lower crosspieces (12, 13). In embodiment 2, the cutting position C1 is determined taking into consideration fitting the vertical panel material end cover 3, so that the vertical panel material end cover 3 does not protrude from the end of the attachment 14, improving work efficiency and usability. In embodiment 1, the position C1 for cutting the upper and lower rails (12, 13) is determined taking into consideration the fitting of the vertical panel material end cover 3, so the inconvenience of the vertical panel material end cover 3 popping out does not occur, as in embodiment 2. The embodiment provides a manufacturing method for the panel body 1 that does not require a separate fastening member such as a spacer, relaxes restrictions on the dimensions to be cut, and is excellent in terms of cost and design. In both embodiments, the cut surfaces of the upper and lower rails (12, 13) and the vertical panel material end cover 3 can be made almost flush with each other.

[0058] Furthermore, the above-described examples and embodiments can be combined by utilizing each other's technologies, so long as there are no particular contradictions or problems in the objects, configurations, and the like. [Explanation of symbols]
