Description

Technical Field

[0001] The present invention relates to a method for manufacturing an architectural panel with an opening and a jig.

Background Art

[0002] Conventionally, it has been known to form an opening in a floor panel for use as an underfloor storage, a wash inspection, a bathroom inspection, or the like. As a method of forming a floor panel with an opening, for example, as disclosed in Patent Document 1, first, a jig having an opening is brought into contact with a predetermined position of the floor panel. Then, while guiding the guided portion of the router by the inner surface of the opening of the jig, the floor material of the floor panel is cut by the cutting portion of the router. Thereby, an opening having a predetermined shape can be provided. A lid is installed in the opening. However, since the lid installed in the opening described in Patent Document 1 is a formal lid, it may be damaged when the floor panel is transported to the site. Therefore, when it is damaged, it is necessary to separately replace the lid. Therefore, it is required to attach the formal lid at the site. However, if the panel with an opening is used with the opening left open without attaching a lid to the opening, it may accidentally fall into the opening during construction at the site. Therefore, it is desirable to provide a temporary lid for the opening.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The present invention has been made in view of the above circumstances, and its purpose is to provide a method for manufacturing an architectural panel with an opening and a jig that allows an opening cover to be easily and quickly temporarily fixed to the opening. [Means for solving the problem]

[0005] The invention described in claim 1 is a method for manufacturing an architectural panel 100 with an opening, which has an opening 2 formed through the thickness direction of the architectural panel 1, as shown in Figures 1 and 3 to 9, Step (I) involves temporarily fixing a plurality of support members 5 to the opening side surface 21 that forms the opening 2 using a jig 3, Step (II) involves positioning and arranging the opening cover 4, which closes the opening 2, on a plurality of support members 5 using the jig 3, The process includes (III) a step of temporarily fixing the positioned opening cover 4 to a plurality of support members 5, The jig 3 comprises a holding portion 34 for holding the support material 5 and a positioning portion 35 for positioning relative to the building panel 1. In step (I) above, with the receiving member 5 held by the holding portion 34 of the jig 3, the positioning portion 35 of the jig 3 is brought into contact with the upper surface 11 of the building panel 1, and the jig 3 and the receiving member 5 are simultaneously brought into contact with the opening side surface 21. After that, the receiving member 5 is temporarily fixed to the opening side surface 21 with the fixing material S2, and then the jig 3 is removed by releasing the holding of the receiving member 5.

[0006] According to the invention described in claim 1, the process comprises steps (I) to (III), in which, with the support member 5 held by the holding portion 34 of the jig 3, the positioning portion 35 of the jig 3 is brought into contact with the upper surface 11 of the building panel 1, while simultaneously bringing the jig 3 and the support member 5 into contact with the opening side surface 21. Therefore, the jig 3 and the support member 5 can be easily positioned relative to the building panel 1. Subsequently, with the support member 5 held in place by the holding part 34 of the jig 3, the support member 5 is temporarily fixed with the fixing member S2, so that the support member 5 can be easily temporarily fixed without shifting from its predetermined position. Furthermore, after temporarily fixing the support member 5, the opening cover 4 positioned on the support member 5 is temporarily fixed to the support member 5. Since the opening 2 is covered by the opening cover 4, it is possible to prevent accidental falls into the opening 2 during construction at the site. As described above, by using the dedicated jig 3, the opening cover 4 can be easily and quickly temporarily fixed to the opening 2.

[0007] The invention described in claim 2 is, for example, as shown in Figures 4 and 5, a method for manufacturing the building panel 100 with an opening as described in claim 1, The jig 3 is characterized in that the length M4 of the holding portion 34 and the receiving member 5 held by the holding portion 34 are shorter than the length M5 of the opening side surface 21.

[0008] According to the invention described in claim 2, the length M4 of the holding portion 34 of the jig 3 and the receiving member 5 held by the holding portion 34 is shorter than the length M5 of the opening side surface 21. Therefore, when the receiving member 5 is temporarily fixed to the opening side surface 21, a gap C1 is formed between the longitudinal end of the receiving member 5 and the opening side surface 21. As a result, the temporarily fixed opening cover 4 can be easily removed by inserting a removal tool such as a crowbar B into the gap C1.

[0009] The invention described in claim 3 is, for example, as shown in Figure 8, a method for manufacturing the building panel 100 with an opening as described in claim 1, Step (II) includes step (II-a), in which the positioning portion 35 of the jig 3 is brought into contact with the opening side surface 21, and the opening cover 4 is placed on a plurality of support members 5 so as to sandwich the positioning portion 35, The positioning portion 35 is used as a spacer to form a gap (second gap C2) between the opening cover 4 and the opening side surface 21.

[0010] According to the invention described in claim 3, step (II) includes step (II-a) of placing the opening cover 4 on a plurality of support members 5 while bringing the positioning portion 35 of the jig 3 into contact with the opening side surface 21, and sandwiching the positioning portion 35. Since the positioning portion 35 is used as a spacer to form a gap C2 between the opening cover 4 and the opening side surface 21, the gap C2 can be easily formed. Then, by inserting a removal tool such as a crowbar B into the gap C2, the opening cover 4 which is temporarily fixed on the support members 5 can be easily removed. Furthermore, the same jig 3 can be used in both the step of temporarily fixing the support member 5 to the opening side surface 21 (I) and the step of placing the opening cover 4 on the support member 5 (II-a). Therefore, it is possible to improve work efficiency and reduce costs.

[0011] The invention described in claim 4 is, for example, as shown in Figures 1 and 10, a method for manufacturing the building panel 100 with an opening as described in claim 2, The support member 5 has a length M4 shorter than the opening side surface 21, and the device is characterized by having a step (IV) of inserting a crowbar B into the gap C1 formed between the longitudinal end of the support member 5 and the opening side surface 21 to remove the opening cover 4 and open the opening 2.

[0012] According to the invention described in claim 4, the length M4 of the support member 5 is shorter than the length M5 of the opening side 21, and the process includes (IV) inserting a crowbar B into the gap C1 formed between the longitudinal end of the support member 5 and the opening side 21 to remove the opening cover 4 and open the opening 2. Therefore, the separate work of forming a hole for inserting the crowbar B with a tool is eliminated, and the opening cover 4 can be smoothly removed by utilizing the gap C1 formed by making the length M4 of the support member 5 shorter than the length M5 of the opening side 21. Thus, the work can be performed in a shorter time.

[0013] The invention described in claim 5 is, for example, as shown in Figure 11, a method for manufacturing the building panel 100 with an opening as described in claim 4, The present invention is characterized by having a step (V) of removing the plurality of support members 5 after the above step (IV).

[0014] According to the invention described in claim 5, since the process includes step (V) of removing the multiple support members 5 after step (IV), permanent support members can be installed on-site in place of the multiple support members 5 that were temporarily fixed.

[0015] The invention described in claim 6 is a jig 3 for attaching a plurality of support members 5 to an opening side surface 21 that forms an opening 2 of a building panel 1, as shown in Figures 1, 3 to 7, for example, The jig comprises a long jig body 31 and two leg members 33 provided on one side edge of the lower surface 311 of the jig body 31 along the longitudinal direction, and at both ends in the longitudinal direction. On the lower surface 311 of the jig body 31, a holding portion 34 for holding the receiving member 5 is formed between the two leg members 33. A positioning portion 35 for positioning the building panel 1 is formed by the lower surface 313 of the jig body 31, where the leg member 33 and the holding portion 34 are not provided, and the side portion 332 of the side of the leg member 33 that faces the lower surface 313. With the support member 5 held by the holding portion 34, the positioning portion 35 is brought into contact with the upper surface 11 of the building panel 1, the jig 3 and the support member 5 are simultaneously brought into contact with the opening side surface 21, the support member 5 is then attached to the opening side surface 21 by the fixing member S2, and then the holding of the support member 5 is released.

[0016] According to the invention described in claim 6, the jig 3 includes a long jig body 31, and two leg members 33 provided along one side edge portion along the longitudinal direction on the lower surface 311 of the jig body 31 and provided at both longitudinal ends respectively. Further, on the lower surface 311 of the jig body 31, a holding portion 34 for holding the receiving member 5 is formed between the two leg members 33. A positioning portion 35 for positioning with respect to the building panel 1 is formed by a lower surface portion 313 of the lower surface 311 of the jig body 31 where the leg members 33 and the holding portion 34 are not provided and a side surface portion 332 of the leg member 33 facing the lower surface portion 313. Then, with the receiving member 5 held in the holding portion 34, the positioning portion 35 is brought into contact with the upper surface 11 of the building panel 1. Therefore, the jig 3 and the receiving member 5 can be easily positioned with respect to the building panel 1. After that, with the receiving member 5 held by the holding portion 34 of the jig 3, the receiving member 5 is attached with the fixing material S2, so that the receiving member 5 can be easily temporarily fixed without being displaced from the predetermined position. As described above, by using the dedicated jig 3, the receiving member 5 can be easily and temporarily fixed to the opening 2 in a short time.

[0017] The invention described in claim 7 is, for example, as shown in FIGS. 3 to 7, in the jig 3 described in claim 6, two of the leg members 33 are provided on the lower surface 311 of the jig body 31 via an intermediate member 32, wherein the intermediate member 32 is long and is continuously provided between the two leg members 33 along the longitudinal direction of the jig body 31.

[0018] According to the invention described in claim 7, two leg members 33 are provided on the lower surface 311 of the jig body 31 via an intermediate member 32, and the intermediate member 32 is long and is continuously provided between the two leg members 33 along the longitudinal direction of the jig body 31. Therefore, by adjusting the thickness of the intermediate member 32, the position in the thickness direction of the holding portion 34 formed between the leg members 33 can be changed. Therefore, the height position of the receiving member 5 held by the holding portion 34 with respect to the opening side surface 21 can be easily adjusted.

Modes for Carrying Out the Invention

[0021] Embodiments will be described below with reference to the drawings. The 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 scope of the present invention is not limited to the examples shown in the drawings, as the drawings are provided for illustrative purposes only.

[0022] [Manufacturing method for building panels with openings] Figure 1 is an exploded perspective view of an architectural panel with an opening. Figure 2 is a cross-sectional view taken along the line ii-ii in Figure 1. The building panel 100 with an opening is preferably a floor panel used for, for example, an underfloor storage compartment, a washroom inspection area, a bathroom inspection area, or an attic inspection area, or a roof panel for a skylight. The following description will use the application of the panel to a floor panel for an underfloor storage compartment as an example, but the present invention is not limited thereto.

[0023] The building panel 100 with an opening has an opening 2 formed by penetrating the building panel 1 in the thickness direction. The opening 2 is rectangular in plan view. In Figure 1, the opening 2 is approximately square in plan view.

[0024] The building panel 1 is formed by attaching a face material 1b to one side of a frame material 1a assembled in a rectangular frame shape. Preferably, the building panel 1 is reinforced with a reinforcing core material (not shown) around the area where the opening 2 is formed. Preferably, the building panel 1 is supported by two support members 12 provided on its lower surface. The support members 12 are elongated rod-shaped members. The two support members 12 are arranged parallel to each other on the opposite side edges of the lower surface of the building panel 1.

[0025] The opening 2 is formed by cutting the face material 1b of the building panel 1. Preferably, the opening 2 of the building panel 1 is formed using, for example, an opening forming jig (not shown) and a tool such as a router or trimmer guided by this opening forming jig. It is preferable to use the surface material cut out by forming the opening 2 for the opening cover 4, which will be described later, as this simplifies the work. Reference numeral 42 denotes a processing hole formed when cutting out the surface material with a router or the like. A cover 4 for the opening 2 of the building panel 1 is temporarily fixed using a special jig 3 (see Figure 3).

[0026] <Jig> Figure 3 is a perspective view of the jig and support material from above. Figure 4 is a perspective view of the jig and support material from below. In the following explanation, "top surface" refers to the upper side (front surface) of the building panel in Figure 1, and "bottom surface" refers to the lower side (back surface) of building panel 1 in Figure 1. As shown in Figure 3, the jig 3 comprises a jig body 31, an intermediate member 32, and a leg member 33. The jig body 31, intermediate member 32, and leg member 33 are plate-shaped members. The intermediate member 32 is provided on the lower surface 311 of the jig body 31, and the leg member 33 is provided on the lower surface 321 of the intermediate member 32.

[0027] The width W2 of the intermediate member 32 and the width W2 of the leg member 33 are approximately equal. The width W2 of the intermediate member 32 and the width W2 of the leg member 33 are smaller than the width W1 of the jig body 31. An intermediate member 32 is provided on one of the side edges of the lower surface 311 of the jig body 31, along the longitudinal direction. One side surface 312 of the jig body 31 along the longitudinal direction and one side surface 323 of the intermediate member 32 along the longitudinal direction are flush with each other. Furthermore, as shown in Figure 4, the lower surface 311 of the jig body 31 has a lower surface portion 313 where the intermediate member 32 is not provided.

[0028] On the lower surface 321 of the intermediate member 32, leg members 33 are provided at both ends in the longitudinal direction. As shown in Figure 3, one side surface 323 of the intermediate member 32 along the longitudinal direction and one side surface 333 of the leg member 33 along the longitudinal direction are flush with each other. Furthermore, as shown in Figure 4, the other side surface 322 of the intermediate member 32 along its longitudinal direction and the other side surface (side portion 332) of the leg member 33 along its longitudinal direction are flush (see Figure 4). The other side surface 322 of the intermediate member 32 along its longitudinal direction and the other side surface (side portion 332) of the leg member 33 along its longitudinal direction face the lower surface portion 313 and are perpendicular to the lower surface portion 313.

[0029] The longitudinal length M1 of the jig body 31 and the longitudinal length M2 of the intermediate member 32 are approximately equal. Furthermore, the lengths M1 of the jig body 31 and M2 of the intermediate member 32 are approximately equal to the length M5 of the opening side surface 21 of the opening 2. The longitudinal length M3 of the leg member 33 is shorter than the longitudinal length M2 of the intermediate member 32. On the lower surface 321 of the intermediate member 32, the space between the two leg members 33 is a holding portion 34 for holding the support member 5, which will be described later. Therefore, the length between these two leg members 33 is approximately equal to the longitudinal length M4 of the support member 5.

[0030] The jig body 31, the intermediate member 32, and the leg member 33 are stacked in this order and then fixed to the jig body 31 from the lower surface 331 of the leg member 33 with fasteners S1 such as screws, nails, or staples.

[0031] A positioning portion 35 for the upper surface (upper surface of the facing material 1b) 11 of the building panel 1 is formed by the lower surface portion 313 of the jig body 311 where the intermediate member 32 is not provided, the other side surface 322 of the intermediate member 32 along the longitudinal direction, and the other side surface (side portion 332) of the leg member 33 along the longitudinal direction. In other words, the jig 3 is positioned by bringing the positioning part 35 into contact with the upper surface 11 that forms the opening 2 of the building panel 1 (see Figure 7).

[0032] Although the jig 3 described above has an intermediate member 32, it may also be configured without the intermediate member 32, with leg members 33 directly attached to both ends in the longitudinal direction on the lower surface 311 of the jig body 31. In this case, the space between the two leg members 33 on the lower surface 311 of the jig body 31 forms a holding portion 34. Furthermore, the positioning portion 35 is formed by the lower surface portion 313 of the lower surface 311 of the jig body 31 where the leg members 33 and the holding portion 34 are not provided, and the other side of the leg member 33 that is aligned in the longitudinal direction (side portion 332).

[0033] The jig 3 described above comprises a long jig body 31 and two leg members 33 provided on one side edge along the longitudinal direction of the lower surface 311 of the jig body 31, and at each end in the longitudinal direction. A holding portion 34 for holding the support member 5 is formed on the lower surface 311 of the jig body 31 between the two leg members 33, and a positioning portion 35 for positioning relative to the building panel 1 is formed by the lower surface portion 313 of the lower surface 311 of the jig body 31 where the leg members 33 and the holding portion 34 are not provided, and the side portion 332 of the side of the leg member 33 facing the lower surface portion 313. As will be described later, with the support member 5 held by the holding portion 34, the positioning portion 35 is brought into contact with the upper surface 11 of the building panel 1. Therefore, the jig 3 and the support member 5 can be easily positioned relative to the building panel 1. Subsequently, with the support member 5 held in place by the holding part 34 of the jig 3, the support member 5 is attached with the fixing material S2, so that the support member 5 can be easily temporarily fixed without shifting from its predetermined position. As described above, by using the dedicated jig 3, the support member 5 can be easily and quickly temporarily fixed to the opening 2.

[0034] Furthermore, two leg members 33 are provided on the lower surface 311 of the jig body 31 via an intermediate member 32. The intermediate member 32 is elongated and is continuously provided between the two leg members 33 along the longitudinal direction of the jig body 31. Therefore, by adjusting the thickness of the intermediate member 32, the position of the holding portion 34 formed between the leg members 33 in the thickness direction can be changed. As a result, the height position of the receiving material 5 held by the holding portion 34 relative to the opening side surface 21 can be easily adjusted.

[0035] Next, we will explain how to temporarily fix the opening cover 4 to the opening 2 of the building panel 1 using the jig 3 described above. For example, in a factory or similar facility, the following steps (I) to (III) are performed to temporarily fix the opening cover 4 to the opening 2 of the building panel 1. Step (I): Multiple support members 5 are temporarily fixed to the opening side surface 21 that forms the opening 2 of the building panel 1 using a jig 3. Step (II): Using the jig 3, the opening cover 4 that closes the opening 2 is positioned and placed on multiple support members 5. Step (III): The positioned opening cover 4 is temporarily fixed to multiple support members 5. Figures 5 and 6 are external perspective views showing process (I). Figure 7 is a cross-sectional view taken along the line vii-vii in Figure 6. Figure 8 is an external perspective view showing process (II). Figure 9 is an external perspective view showing process (III).

[0036] <Process (I)> In step (I), as shown in Figure 5, a jig 3 is used to temporarily fix multiple support members 5 to the opening side surface 21 that forms the opening 2 of the building panel 1. The support member 5 is a rod-shaped piece of timber. The support member 5 is temporarily fixed to each of the four opening sides 21 that form the opening 2. The longitudinal length M4 of the support member 5 is shorter than the length M5 of the opening side 21. Therefore, when the support member 5 is temporarily fixed to the opening side 21, a gap C1 is formed between the longitudinal end of the support member 5 and the opening side 21. That is, among the multiple support members 5 temporarily fixed to the opening side 21, a gap C1 is formed between the ends of adjacent support members 5. A crowbar B, which is used to remove the opening cover 4, is inserted into the gap C1, as will be described later (see Figure 10).

[0037] As a method for temporarily fixing multiple support members 5, first, the support members 5 are held in the holding portion 34 of the jig 3 (see Figure 5). That is, the support members 5 are positioned between the two leg members 33 on the lower surface 321 of the intermediate member 32 of the jig 3. With the support members 5 held between the two leg members 33 in this manner, the positioning portion 35 of the jig 3 is brought into contact with the upper surface 11 of the building panel 1, and the jig 3 and the support members 5 are simultaneously brought into contact with the opening side surface 21 (see Figures 6 and 7). Next, the support member 5 is temporarily fixed to the opening side surface 21 with a fixing material S2. For the fixing material S2, for example, screws, nails, or staples can be used. Since it is a temporary fixation, it is preferable to use screws, nails, or staples as the fixing material S2 without using adhesive, as it is easy to remove. From the viewpoint of saving time, it is preferable to fix the support member 5 at two points on both ends of the support member 5 with the fixing material S2. Afterward, the jig 3 is removed by releasing the support member 5. In this way, the support member 5 is temporarily fixed to each of the four opening sides 21 using the jig 3. The four temporarily fixed support members 5 each have a horizontal upper surface. Also, as shown in Figure 2, the upper surfaces 51 of the four temporarily fixed support members 5 are positioned lower than the upper surface 11 of the facing material 1b of the building panel 1. In other words, on the opening side, the upper surface 51 of the support member 5 is positioned lower than the upper surface 11 of the facing material 1b by the thickness H1 of the opening cover 4. As a result, when the opening cover 4 is placed on the upper surface 51 of the support member 5, the upper surface 41 of the opening cover 4 and the upper surface 11 of the facing material 1b are flush.

[0038] <Process (II)> In step (II), as shown in Figure 8, the opening cover 4 that closes the opening 2 is positioned and placed on multiple support members 5 using the jig 3. The opening cover 4 has a shape similar to that of the opening 2, and in a plan view, it is roughly square. The dimensions of the opening cover 4 are slightly smaller than those of the opening 2. However, the dimensions of the opening cover 4 are such that when placed on the support members 5, it does not fall into the opening 2 and can be placed on the four support members 5.

[0039] The jig 3 used in process (II) is the same as the jig 3 used in process (I). However, in process (I), the jig body 31 was used horizontally with the top surface facing horizontally, whereas in process (II), the jig body 31 is used vertically with the top surface facing vertically. Specifically, the leg member 33 of the jig 3 is oriented toward the side of the facing material 1b opposite to the opening 2. Then, the side of the leg member 33 along its longitudinal direction is placed on the upper surface 11 of the facing material 1b and engaged, thereby bringing the positioning part 35 into contact with the opening side surface 21. In this state, the opening cover 4 is placed on multiple support members 5 so as to sandwich the positioning part 35 (step (II-a) (see Figure 8)). In this way, the positioning portion 35 is used as a spacer to form a second gap C2 (see Figure 10) between the side surface of the opening cover 4 and the opening side surface 21.

[0040] <Process (III)> In step (III), as shown in Figure 9, the positioned opening cover 4 is temporarily fixed to multiple support members 5. The positioned opening cover 4 is fixed to the support member 5 from the upper surface 41 of the opening cover 4 by fixing materials S3 at predetermined intervals. The fixing materials S3 can be the same as the fixing materials S2 used to fix the support member 5. For example, screws, nails, or staples can be used as fixing materials S3. Since it is a temporary fixation and easy to remove, it is preferable to use screws, nails, or staples as fixing materials S3 without using adhesive.

[0041] It is preferable to perform steps (I) to (III) above at the factory, and then transport the building panel 100 with the opening and opening cover 4 temporarily fixed to the site, and then perform steps (IV) and (V) below. Figure 10 is an external perspective view showing step (IV). Figure 11 is an external perspective view showing step (V).

[0042] <Process (IV)> In step (IV), as shown in Figure 10, since the length M4 of the support member 5 is shorter than the length M5 of the opening side 21, a crowbar B is inserted into the gap C1 formed between the longitudinal end of the support member 5 and the opening side 21 to remove the opening cover 4 and open the opening 2. Since the opening cover 4 is slightly smaller than the dimensions of the opening 2, a second gap C2 is formed between the side of the opening cover 4 and the opening side 21. Also, since the length M4 of the support member 5 is shorter than the length M5 of the opening side 21, a gap C1 is formed between the ends of adjacent support members 5 that are temporarily fixed to the opening side 21. Therefore, the opening cover 4 is removed by inserting a crowbar B through the second gap C2 located above the gap C1 (see Figure 10). The crowbar B can be easily inserted into the gap C1 and the second gap C2 by striking the handle end with a hammer or the like.

[0043] <Process (V)> In step (V), multiple support members 5 are removed as shown in Figure 11. It is preferable that the multiple support members 5 be removed using a removal tool such as a crowbar, in the same manner as the opening cover 4.

[0044] After step (V), it is preferable to attach a formal support member to the opening side 21 and a formal cover to the opening 2.

[0045] This embodiment provides the following excellent effects. The manufacturing method for the building panel 100 with an opening comprises steps (I) to (III). In step (I), while the support member 5 is held in the holding portion 34 of the jig 3, the positioning portion 35 of the jig 3 is brought into contact with the upper surface 11 of the building panel 1, and the jig 3 and the support member 5 are simultaneously brought into contact with the side surface 21 of the opening. Therefore, the jig 3 and the support member 5 can be easily positioned relative to the building panel 1. Subsequently, with the support member 5 held in place by the holding part 34 of the jig 3, the support member 5 is temporarily fixed with the fixing member S2, so that the support member 5 can be easily temporarily fixed without shifting from its predetermined position. Furthermore, after temporarily fixing the support member 5, the opening cover 4 positioned on the support member 5 is temporarily fixed to the support member 5. Since the opening 2 is covered by the opening cover 4, it is possible to prevent accidental falls into the opening 2 during construction at the site. As described above, by using the dedicated jig 3, the opening cover 4 can be easily and quickly temporarily fixed to the opening 2.

[0046] Furthermore, since the length M4 of the holding portion 34 of the jig 3 and the receiving member 5 held by the holding portion 34 are shorter than the length M5 of the opening side surface 21, a gap C1 is formed between the longitudinal end of the receiving member 5 and the opening side surface 21 when the receiving member 5 is temporarily fixed to the opening side surface 21. Therefore, the temporarily fixed opening cover 4 can be easily removed by inserting a removal tool such as a crowbar B into the gap C1.

[0047] Step (II) includes step (II-a), in which the positioning portion 35 of the jig 3 is brought into contact with the opening side surface 21, and the opening cover 4 is placed on a plurality of support members 5 so as to sandwich the positioning portion 35. The positioning portion 35 is used as a spacer to form a gap (second gap C2) between the opening cover 4 and the opening side surface 21, so that the gap C2 can be easily formed. Then, by inserting a removal tool such as a crowbar B into the gap C2, the opening cover 4 which is temporarily fixed on the support members 5 can be easily removed. Furthermore, the same jig 3 can be used in both the step of temporarily fixing the support member 5 to the opening side surface 21 (I) and the step of placing the opening cover 4 on the support member 5 (II-a). This results in improved work efficiency and reduced costs.

[0048] The manufacturing method for the building panel 100 with an opening includes a step (IV) in which a crowbar B is inserted into a gap C1 formed between the longitudinal end of the support member 5 and the opening side 21, thereby removing the opening cover 4 and opening the opening 2, because the length M4 of the support member 5 is shorter than the length M5 of the opening side 21. Therefore, the work of separately forming a hole for inserting the crowbar B with a tool is eliminated, and the opening cover 4 can be smoothly removed by utilizing the gap C1 formed by making the length M4 of the support member 5 shorter than the opening side 21. Thus, the work can be performed in a shorter time. Furthermore, since the process includes step (V) of removing multiple support members 5 after step (IV), permanent support members can be installed on-site in place of the temporarily fixed support members 5.

[0049] Furthermore, in recent years, there has been a growing demand for the realization of a decarbonized society through the promotion of carbon neutrality, which aims to reduce carbon dioxide emissions to virtually zero, and for the achievement of the Sustainable Development Goals (SDGs). In the construction industry, efforts are also being made to use wood in buildings, which reduces carbon dioxide emissions. The above-mentioned building panels and other materials utilize wood-based materials, and therefore can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and the achievement of the SDGs.

[0050] [Differentiation] The embodiments to which the present invention can be applied are not limited to those described above, and can be modified as appropriate without departing from the spirit of the invention. Modifications are described below. The following modifications may be combined as much as possible. Furthermore, in each of the following modifications, elements common to the above-described embodiments are denoted by the same reference numerals, and their descriptions are omitted or simplified.

[0051] Figure 12 is an exploded perspective view of a modified building panel with an opening. Figure 13 is an external perspective view showing process (I) in Figure 12. In the above embodiment, the opening 2 is approximately square in plan view, but it may be approximately rectangular as shown in Figure 12. When the opening 2 is approximately rectangular in plan view, it is preferable to temporarily fix two support members 5 to each of the four opening sides 21, specifically the opening sides 22 on the longer side. It is also preferable to temporarily fix one support member 5 to each of the four opening sides 21, specifically the opening sides 23a and 23b on the shorter side. Hereinafter, the opening side 22 on the longer side will be referred to as the long-side opening side 22, and the opening sides 23a and 23b on the shorter side will be referred to as the short-side opening side 23.

[0052] In the step of temporarily fixing the two support members 5 to the long side opening surface 22, the same jig 3 as in the above embodiment is used. First, the first support member 5 is held in the holding portion 34 of the jig 3 in the same manner as in Figure 5. That is, with the support member 5 held between the two leg members 33, the positioning portion 35 of the jig 3 is brought into contact with the upper surface 11 of the building panel 1, and the jig 3 and the support member 5 are brought into contact with the long-side opening surface 22 simultaneously. At this time, as shown in Figure 13, the positioning relative to the long-side opening surface 22 can be achieved by bringing one end face 3a in the longitudinal direction of the jig 3 into contact with the short-side opening surface 23a opposite to the end face 3a. In this way, the jig 3 is positioned closer to the short-side opening surface 23a of the long-side opening surface 22. Then, with the jig 3 and the support member 5 positioned on the long side opening surface 22, the support member 5 is fixed to the long side opening surface 22 with the fixing member S2.

[0053] Similarly, the second support member 5 is also held in the holding portion 34 of the jig 3 in the same manner as in Figure 5. With the support member 5 held in the holding portion 34, the positioning portion 35 of the jig 3 is brought into contact with the upper surface 11 of the building panel 1, and the jig 3 and the support member 5 are simultaneously brought into contact with the longitudinal opening side surface 22. At this time, as shown in Figure 13, the other end face 3b of the jig 3 in the longitudinal direction is brought into contact with the short-side opening side surface 23b opposite to the end face 3b, thereby positioning relative to the long-side opening side surface 22. In this way, the jig 3 is positioned closer to the short-side opening surface 23b of the long-side opening surface 22. Then, with the jig 3 and the support member 5 positioned on the long side opening surface 22, the support member 5 is fixed to the long side opening surface 22 with the fixing member S2.

[0054] As described above, the support member 5 is temporarily fixed to the long side opening surface 22. Note that, except for the number of support members 5 temporarily fixed to the long side opening surface 22, this is the same as the embodiment described above; therefore, the same reference numerals are used for similar components and their descriptions are omitted.

[0055] Furthermore, although the number of support members 5 is set to be provided on each of the four opening sides 21, they may be provided on only two opposing opening sides 21, for example, and the number of support members 5 can be changed as appropriate, as long as the opening cover 4 does not bend under load from above. Furthermore, the shape of opening 2 may not be rectangular. Furthermore, to remove the opening cover 4, instead of using the gap C1 and the second gap C2, for example, the processing hole 42 formed in the opening cover 4 may be used. The opening cover 4 may also be removed by inserting a crowbar B into this hole 42. [Explanation of symbols]
