Summary of the Invention

Problems to be Solved by the Invention

[0004] Construction panels are placed on a temporary storage tool in a flat stacked state in which a plurality of construction panels are stacked. Therefore, the construction panels (except for the construction panel arranged at the uppermost stage) support the construction panel arranged above the construction panel, so that a load is concentrated on a predetermined part of the construction panel, and the predetermined part may be damaged. The present invention has been made in view of the above circumstances, and its problem is to prevent Roof panels (installed as roofs for buildings) construction panels ) from being damaged during temporary storage.

Means for Solving the Problems

[0005] The invention described in claim 1 is a roof panel (gable panel 10) installed as the roof of a building, as shown in Figures 1, 5, and 7, A roof panel with spacers, the spacers 20 of which are fixed in a removable manner. It has a protruding portion (connecting portion 14) that protrudes from the lower surface of the panel body 11, On the lower surface of the panel body 11, The aforementioned Spacer 20 is fixed in a removable manner. The aforementioned lower surface is the surface located on the lower side when it is installed as a roof. The aforementioned protruding portion protrudes from the lower surface of the panel body 11 in both the state in which it is temporarily placed and the state in which it is installed as a roof. The spacer 20 is attached to the panel body 11 when it is temporarily placed, and is removed from the panel body 11 when it is installed as a roof. The thickness dimension of the spacer 20 is set to be approximately the same as the protruding dimension of the protruding portion, and the spacer 20 and the protruding portion are configured to contact the temporary holder (wooden block R) when the spacer is temporarily placed. Occasionally, The spacer 20 is a plate, and one end of the spacer 20 in the longitudinal direction protrudes outward from the side end face of the panel body 11. It is characterized by being present.

[0006] According to the invention described in claim 1, a spacer 20 is attached to a roof panel (gable panel 10) having a protruding portion (connecting portion 14). Therefore, when temporarily placed, a roof panel positioned above the roof panel (gable panel 10) can be supported not only by the protruding portion (connecting portion 14) but also by the spacer 20. As a result, the load does not concentrate on a predetermined part of the roof panel (gable panel 10) (for example, the protruding portion), and damage to that predetermined part during temporary placement can be prevented. Furthermore, since the spacer 20 is attached to the roof panel (gable panel 10) with the protruding portion 21 provided, it not only prevents damage to the roof panel during temporary placement, but also functions as a marker to confirm whether or not the roof panel has a protruding portion (connecting portion 14), and as a marker to confirm that the roof panel is placed in the correct position on the timber R.

[0007] The invention described in claim 2 is, for example, as shown in Figures 1, 5, and 7, as described in claim 1. roof In the panel (gable panel 10), The roof A pair of spacers 20 are attached to one end of the panel in the shorter direction, with space between them. The roof A pair of spacers 20 are attached to the other end of the panel in the shorter direction, spaced apart from each other. One of the pair of spacers 20 is the roof It is attached to one end of the panel in the longitudinal direction, The other of the pair of spacers 20 is the roof It is characterized by being attached to the other end in the longitudinal direction of the panel.

[0008] According to the invention described in claim 2, roof Since spacers 20 are attached to the four corners of the panel (gable panel 10), when stacked flat... roof The panel can be temporarily placed in a stable position.

[0011] Claim 3 The invention described is as shown in Figures 1, 5, and 7, for example, according to the claims. 1 In the roof panel (gable panel 10) described above, The spacer 20 is characterized in that both longitudinal ends of the spacer 20 are fixed to the panel body 11 using nails N.

[0012] Claim 3 According to the invention described above, the spacer 20 is fastened to the roof panel (gable panel 10) at two points with nails N. Therefore, the spacer 20 can be removed from the roof panel simply by striking the protruding portion 21 of the spacer 20 (the portion that protrudes outward from the side end face of the panel body 11) from above with a hammer H. Furthermore, the lever principle comes into play, allowing the spacer 20 to be removed with little force, thus making the removal of the spacer 20 an efficient task.

[0013] Claim 4The invention described in [claim number] is, as shown in FIGS. 1 and 5 for example, in the roof panel (keraba panel 10) described in claim 1, the roof panel is temporarily placed in an integrated state with another roof panel (roof panel 1a) that does not have the protruding portion (connecting portion 14), and is provided as a roof while remaining in that integrated state, the spacer 20 is also removably fixed to the other roof panel, and the spacer 20 is attached to the other roof panel in the temporarily placed state and removed from the other roof panel in the state of being provided as a roof, which is characterized.

[0014] Claim 4 According to the invention described in [claim number], not only the roof panel (keraba panel 10) having the protruding portion (connecting portion 14), but also the spacer 20 is attached to another roof panel (roof panel 1a) that is temporarily placed in an integrated state with the roof panel. Therefore, at the time of temporary placement, the roof panel arranged above the roof panel (keraba panel 10) can be supported not only by the protruding portion (connecting portion 14) and the spacer 20 attached to the roof panel (keraba panel 10), but also by the spacer 20 attached to another roof panel (roof panel 1a) in an integrated state with the roof panel (keraba panel 10). As a result, even when the roof panel (keraba panel 10) having the protruding portion (connecting portion 14) is temporarily placed in an integrated state with another roof panel (roof panel 1a), a load does not concentrate on a predetermined portion (for example, the protruding portion) of the roof panel (keraba panel 10), and breakage of the predetermined portion at the time of temporary placement can be prevented.

[0015] Claim 5 The invention described in [claim number] is, as shown in FIGS. 1 to 5 and 7 for example, in the roof panel described in claim 1, the roof panel is a keraba panel 10 that constitutes the keraba of the roof, the panel body 11, and a keraba base material 12 fixed to the panel body 11, and is provided with them. The aforementioned protruding portion (connecting portion 14) is provided on the gable base material 12, The soffit material 30 is fixed to the panel body 11 via the gable base material 12.

[0016] Claim 5 According to the invention described above, a spacer 20 is attached to the gable panel 10. Therefore, when temporarily placing the panels, roof panels positioned above the gable panel 10 can be supported not only by the protruding portion (connecting portion 14) of the gable base material 12 but also by the spacer 20. Thus, even when temporarily placing the panels with the gable base material 12 fixed to the panel body 11, the gable base material 12 (especially the protruding portion) will not be damaged, and the installation of the roof panels can be carried out without the extra effort of attaching the gable base material 12 to the panel body 11 at the construction site to construct the gable panel 10.

[0017] Claim 6 The invention described herein is a method for constructing roof panels that are installed as the roof of a building, as shown in Figures 1 to 5 and 7, The aforementioned roof panel includes a first roof panel (gable panel 10) in which a spacer 20 is removably fixed to the lower surface of the panel body 11 when temporarily placed, and a second roof panel (roof panel 1a) in which the spacer 20 is not fixed. The first roof panel (gable panel 10) is the roof panel described in claim 1, In the temporary placement state, the first roof panel is positioned at the bottom, and the second roof panel is positioned anywhere other than the bottom. before The first roof panel is characterized by being installed as a roof after the spacer 20 has been removed.

[0018] Claim 6According to the invention described above, the first roof panel (gable panel 10) having a protruding portion (connecting portion 14) is the roof panel that is placed in the lowest position during temporary placement, and a spacer 20 is attached to the first roof panel (gable panel 10). Therefore, during temporary placement, the entire stacked roof panel can be supported not only by the protruding portion (connecting portion 14) but also by the spacer 20, so that the load does not concentrate on a predetermined part (for example, the protruding portion) of the first roof panel (gable panel 10) that is placed in the lowest position, and damage to that predetermined part during temporary placement can be prevented. [Effects of the Invention]

[0019] According to the present invention, it is possible to prevent damage to building panels when they are temporarily placed in position. [Brief explanation of the drawing]

[Figure 7] This is a diagram explaining how to remove the spacer. [Modes for carrying out the invention]

[0021] Embodiments of the present invention will be described below with reference to the drawings. However, while the embodiments described below are subject to various technically preferred limitations for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples. The directions in the following embodiments and illustrated examples are set solely for the convenience of explanation.

[0022] In Figure 1, reference numeral 10 denotes a gable panel that constitutes the gable end of the roof, which is part of the roof panel 1a. The roof panel 1a (including the gable panel 10) in this embodiment is a wooden building panel used in panel construction. In this context, panel construction is a method of building construction in which building components such as walls, floors, and roofs are prefabricated into panels in a factory, and then these panels (architectural panels such as wall panels 1b, floor panels, and roof panels 1a) are assembled at the construction site to build the building.

[0023] Furthermore, a building panel is constructed by assembling vertical and horizontal frame members 2 into a rectangular shape to form a rectangular frame, and then assembling auxiliary cross members 3 vertically and horizontally inside this rectangular frame to form a frame body, with facing material 4 attached to one or both sides of this frame body, resulting in a hollow internal structure. The hollow internal part (the back side of the facing material 4) is usually filled with insulation material such as glass wool or rock wool. In this embodiment, the roof panel 1a does not have a facing material 4 attached to its lower surface, but only to one side (the upper surface).

[0024] As shown in Figure 1, the gable panel 10 of this embodiment is bonded and / or secured to the other roof panels 1a with adhesive (and / or with connecting members such as bolts) to form an integrated unit. In other words, the gable panel 10 of this embodiment is transported from the factory to the construction site in an integrated state with the other roof panels 1a, and is installed on top of the wall panels 1b, etc., in that integrated state.

[0025] As shown in Figures 1 to 3, the gable panel 10 is composed of a panel body 11 (frame material 2, auxiliary battens 3, and facing material 4) and a plurality of gable base materials 12. As shown in Figure 4, the soffit material 30 is fixed to the underside of the gable portion 111 of the panel body 11 (i.e., the gable end of the roof (such as a gable roof or a shed roof) that protrudes from the exterior wall) by fasteners (nails N, etc.), adhesive, or a combination thereof. Specifically, as shown in Figure 1, on the underside of the gable portion 111, multiple (two in this embodiment) gable underlayment materials 12 are arranged in multiple rows (two in this embodiment) in the short direction (front-back direction) of the gable panel 10, and the gable underlayment materials 12 are arranged in multiple rows (two in this embodiment) in the short direction (front-back direction) of the gable panel 10. In other words, the gable panel 10 of this embodiment is equipped with four gable underlayment materials 12. The soffit material 30 is then attached to the gable portion 111 via these gable underlayment materials 12. Figures 2 and 3 show the state before the soffit material 30 is attached.

[0026] As shown in Figures 2 and 3, the gable underlayment 12 is not provided at the eaves. That is, if the gable underlayment 12 extends to the eaves, it will interfere with the fascia board member, so to avoid this, the gable underlayment 12 is not provided at the eaves. Also, as shown in Figure 3, a support member 40 for receiving the soffit underlayment plywood at the eaves is provided on the lower side of the gable panel 10, but the remaining material cut to adjust the length of the gable underlayment 12 may be used as this support member 40. Furthermore, the front gable base material 12 (the gable base material 12 provided on the front end side of the gable portion 111) may be a single gable base material 12 rather than a series of continuous gable base materials 12. Furthermore, the rear gable base material 12 (the gable base material 12 provided on the rear end side of the gable portion 111) may be a single gable base material 12 rather than a series of continuous gable base materials 12.

[0027] As shown in Figures 1 to 4, the gable base material 12 is composed of multiple base body sections 13 and one connecting section 14. The base body portion 13 is, for example, a wooden square timber and is installed between the frame members 2 and auxiliary members 3 that extend in the front-to-back direction, or between the auxiliary members 3 that extend in the front-to-back direction, among the frame members 2 and auxiliary members 3 that constitute the panel body 11. The base body portion 13 is fixed to the connecting portion 14 by fasteners (screws, etc.), adhesive, or a combination thereof.

[0028] The length (horizontal dimension) of the base body portion 13 provided between the frame member 2 and the auxiliary cross member 3 is approximately equal to the distance between the frame member 2 and the auxiliary cross member 3. In other words, the base body portion 13 provided between the frame member 2 and the auxiliary cross member 3 is designed to fit snugly between them. The base body portion 13 provided between the frame member 2 and the auxiliary cross member 3 is then fixed to the frame member 2 by fasteners (screws, etc.), adhesive, or a combination thereof. Furthermore, the length dimension (horizontal dimension) of the base body portion 13 provided between the auxiliary battens 3 is approximately equal to the distance between the auxiliary battens 3. In other words, the base body portion 13 provided between the auxiliary battens 3 is designed to fit snugly between them. Therefore, in the gable base material 12, gaps are provided between the base body parts 13, and the spacing dimension of these gaps is set to be approximately equal to the thickness dimension (left-right dimension) of the auxiliary battens 3 that extend in the front-rear direction among the auxiliary battens 3 that constitute the panel body 11.

[0029] The connecting portion 14 is, for example, a wooden square timber, and connects multiple base body portions 13 with a gap (a gap whose spacing dimension is approximately equal to the thickness dimension of the auxiliary battens 3) between them. The upper surface of the connecting portion 14 is provided in contact with the lower surface of the auxiliary battens 3 that extend in the front-rear direction among the auxiliary battens 3 that constitute the panel body 11, and is fixed to the auxiliary battens 3 by fasteners (screws, etc.), adhesive, or a combination thereof. That is, the lower surface of the base body portion 13 is flush with the lower surface of the panel body 11 (the lower surface of the frame material 2 and the auxiliary battens 3 that extend in the front-rear direction), and the lower part of the gable base material 12 (i.e., the connecting portion 14) protrudes downward from the panel body 11.

[0030] The construction panels are transported from the factory to the construction site and temporarily placed in a flat stack, as shown in Figure 5, in a material storage area at the construction site. At this time, temporary support blocks called "linki" (or "rinki" or "rinki") R are laid between the ground and the construction panels to prevent them from directly touching the ground. Since the gable panel 10 is a roof panel 1a that forms the edge of the roof, it is installed first and last among the roof panels 1a. To improve the efficiency of the installation work, as shown in Figure 5, the gable panel 10 to be installed first among the roof panels 1a is often temporarily placed at the top, and the gable panel 10 to be installed last among the roof panels 1a is often placed at the bottom.

[0031] As shown in Figures 1 and 5, a spacer 20 is attached to the underside of the gable panel 10, which is positioned at the bottom during temporary placement. A spacer 20 is also attached to the underside of the roof panel 1a, which is integrated with the gable panel 10, which is positioned at the bottom during temporary placement. The spacers (gable base spacers) 20 are detachably fixed to the gable panel 10 and the roof panel 1a, which is integrated with the gable panel 10, using nails N. The gable panel 10 (and the roof panel 1a integrated with the gable panel 10) which is placed at the bottom during temporary placement is transported from the factory to the construction site with the spacers 20 attached, and is temporarily placed on the wooden blocks R laid in the material storage area at the construction site with the spacers 20 still attached. Then, as shown in Figures 2 and 3, the gable panel 10 (and the roof panel 1a integrated with the gable panel 10) is installed on top of the wall panel 1b, etc., with the spacers 20 removed. In other words, the spacers 20 are removed at the construction site when the gable panel 10 (and the roof panel 1a integrated with the gable panel 10) is in use.

[0032] Spacers 20 are attached to the gable panel 10 on both the left and right sides of the front end of the gable panel 10 and on both the left and right sides of the rear end of the gable panel 10. In other words, four spacers 20 are attached to the gable panel 10. Specifically, the spacers 20 attached to the gable panel 10 are fixed to the lower surface of the frame material 2 that constitutes the panel body 11 by nails N, with their longitudinal direction aligned with the left and right direction. Furthermore, the roof panel 1a, which is integrated with the gable panel 10, has spacers 20 attached to both the left and right sides of its rear end (the end opposite to the side adjacent to the gable panel 10). In other words, the roof panel 1a, which is integrated with the gable panel 10, has two spacers 20 attached to it. Specifically, the spacers 20 attached to the roof panel 1a, which is integrated with the gable panel 10, are fixed to the underside of the frame material 2 that constitutes the roof panel 1a by nails N, with their longitudinal direction aligned with the left-right direction.

[0033] Spacer 20 is made of a board material such as MDF (Medium Density Fiberboard) or plywood. The thickness dimension (vertical dimension) of the spacer 20 is set to be approximately equal to the thickness dimension (vertical dimension) of the connecting portion 14 in the gable base material 12, and in this embodiment, it is set to 9 mm. Furthermore, the width dimension (front-to-back dimension) of the spacer 20 is set to be longer than the width dimension (front-to-back dimension) of the frame material 2 that extends in the left-to-right direction, and in this embodiment, it is set to approximately 40 mm.

[0034] The gable underlayment 12 is provided only on the gable portion 111 of the panel body 11, and furthermore, the connecting portion 14 of the gable underlayment 12 protrudes from the lower surface of the panel body 11. Therefore, for example, as shown in Figure 6(a), if the spacer 20 is not attached to the gable panel 10 (and the roof panel 1a integrated with the gable panel 10) that is placed in the lowest position during temporary placement, the gable underlayment 12 (especially the connecting portion 14) of the gable panel 10 placed in the lowest position will support the entire flat-stacked roof panel 1a, which can lead to problems such as unintended load being placed on a predetermined part (e.g., the connecting portion 14) of the lowest roof panel 1a causing damage to that predetermined part, or the entire flat-stacked roof panel 1a tilting and causing the load to collapse.

[0035] Furthermore, as shown in Figure 6(b), for example, when the front gable base material 12 is temporarily placed detached from the timber R, the entire stacked roof panel 1a is supported only by the rear gable base material 12. This can easily lead to problems such as unintended stress being placed on a specific part of the bottom roof panel 1a (for example, the connecting part 14 in the rear gable base material 12), causing damage to that part, or the entire stacked roof panel 1a tilting and causing the load to collapse.

[0036] To solve these problems, in this embodiment, as shown in Figures 1 and 5, spacers 20 are attached to the four corners of the gable panel 10 that is placed in the lowest position during temporary placement (and the two corners on the opposite side of the gable panel 10 of the roof panel 1a that is integrated with the gable panel 10). By attaching the spacers 20 in this way, the entire roof panel 1a in the flat stacked state can be supported by both the gable base material 12 and the spacers 20, so the entire roof panel 1a in the flat stacked state does not tilt and can be temporarily placed in a stable state.

[0037] Even when spacers 20 are attached to the gable panel 10, it is preferable to temporarily place it in the correct position on the timber R (i.e., with both the front gable base material 12 and the rear gable base material 12 positioned on the timber R), as shown in Figure 5(a). However, by attaching spacers 20 to the gable panel 10, the above problem becomes less likely. In other words, by attaching spacers 20 to the gable panel 10, even when the front gable base material 12 is temporarily placed detached from the timber R, as shown in Figure 5(b), the entire flat-stacked roof panel 1a can be supported not only by the rear gable base material 12, but also by the spacers 20 attached to the rear end of the gable panel 10 and the spacers 20 attached to the rear end of the roof panel 1a which is integrated with the gable panel 10, thus making the above problem less likely.

[0038] As shown in Figures 1 and 7, the spacer 20 is attached to the gable panel 10 (and the roof panel 1a integrated with the gable panel 10) such that one of its left or right end is a protruding portion 21 that extends outward from the gable panel 10 (and the roof panel 1a integrated with the gable panel 10). Specifically, of the left and right spacers 20 attached to the gable panel 10, the left end of the left spacer 20 protrudes to the left of the left end surface of the panel body 11, and the right end of the right spacer 20 protrudes to the right of the right end surface of the panel body 11. Similarly, of the left and right spacers 20 attached to the roof panel 1a integrated with the gable panel 10, the left end of the left spacer 20 protrudes to the left of the left end surface of the roof panel 1a, and the right end of the right spacer 20 protrudes to the right of the right end surface of the roof panel 1a.

[0039] By attaching the spacer 20 to the gable panel 10 with the protruding portion 21 provided, the spacer 20 serves as a marker to confirm that the building panel placed at the bottom is the gable panel 10, and as a marker to confirm that the building panel is placed in the correct position on the lintel R. In other words, by providing a protruding portion 21 on the spacer 20, it is possible to check whether the spacer 20 is installed and whether the building panel placed on the lowest level is a gable panel 10 without having to look up at the building panel placed on the lowest level from below. This makes it possible to efficiently remove the spacer 20 and install the building panel. Furthermore, when, for example, stacking building panels flat and lifting them with a crane to place them on the wooden platform R, the operator must operate the crane while ensuring that no part of the gable panel 10 located on the bottom level (for example, the front end (i.e., the part including the front gable base material 12)) is temporarily placed detached from the wooden platform R. The protruding portion 21 of the spacer 20 serves as a marker for this confirmation, making it possible to load and unload building panels efficiently.

[0040] Furthermore, by providing a protruding portion 21 on the spacer 20, when removing the spacer 20 from the gable panel 10 (and the roof panel 1a integrated with the gable panel 10), the spacer 20 can be struck from above with a hammer H to remove the nail N. In other words, the protruding portion 21 can be used as the part struck with a hammer H when removing the spacer 20 from the gable panel 10 (and the roof panel 1a integrated with the gable panel 10). By providing a protruding portion 21 on the spacer 20, the spacer 20 can be removed from the gable panel 10 simply by striking it with a hammer H, thus making the removal of the spacer 20 easier. In this embodiment, the projection dimension (protrusion dimension) of the protruding portion 21 is set to 45 mm, but it is not limited to this. The projection dimension of the protruding portion 21 can be appropriately selected as long as the protruding portion 21 functions as a marker as described above, and a dimension that is easy to strike with a hammer H is preferred.

[0041] Furthermore, as shown in Figures 1 and 7, the left and right ends of the spacer 20 are fixed to the frame material 2 using nails N. That is, since the spacer 20 is fixed at two points, the nails N can be removed using the lever principle, and the force required to strike the protruding part 21 of the spacer 20 with a hammer H when removing the spacer 20 is reduced. In other words, the spacer 20 can be removed with less force compared to when the spacer 20 is fixed at three or more points using nails N. Note that the fasteners for fixing the spacer 20 to the building panel are not limited to nails N, but may also be staples, etc., and from the viewpoint of ease of removal, it is preferable not to use fasteners that have a spiral groove on the shaft (such as screws).

[0042] Furthermore, in this embodiment, the distance W between the left and right spacers 20 is set to a dimension shorter than the distance between the fork tines of a forklift (for example, less than 455 mm). As a result, when transporting the roof panels 1a in a flat stacked state with a forklift, both the left and right spacers 20 are positioned on the fork tines, making it possible to transport them in a stable state.

[0043] This embodiment provides the following excellent effects. In other words, the gable panel 10 of this embodiment is a building panel having a connecting portion 14 that protrudes from the lower surface of the panel body 11, and a spacer 20 is removably fixed to the lower surface of the panel body 11, and the thickness dimension of the spacer 20 is set to be approximately the same as the protruding dimension of the connecting portion 14. Therefore, when temporarily placed, building panels positioned above the gable panel 10 can be supported not only by the connecting portion 14 but also by the spacer 20. This prevents the load from concentrating on a specific part of the gable panel 10 (for example, the connecting portion 14), thus preventing damage to that specific part during temporary placement.

[0044] In this embodiment, "temporary storage" includes not only the time when the materials are temporarily stored at a material storage area at the construction site, but also other times (for example, when stacked building panels are transported from the factory to the construction site on wooden blocks R, this includes the time of transport). In other words, in this embodiment, "temporary storage" refers to the time when multiple stacked building panels are placed on temporary storage devices such as wooden blocks R. Furthermore, the building panels are not limited to building panels used in panel construction methods, but may also be building panels used in other construction methods (for example, 2x4 panels used in 2x4 construction methods). Furthermore, the protruding portion that extends from the lower surface of the panel body 11 is not limited to the connecting portion 14 of the gable base material 12.

[0045] Furthermore, in the gable panel 10 of this embodiment, a pair of spacers 20 (left and right spacers 20) are attached to one end (front end) in the short direction of the gable panel 10, spaced apart from each other, and a pair of spacers 20 (left and right spacers 20) are attached to the other end (rear end) in the short direction of the gable panel 10, spaced apart from each other, with one of the pair of spacers 20 attached to one end (left end) in the longitudinal direction of the gable panel 10, and the other of the pair of spacers 20 attached to the other end (right end) in the longitudinal direction of the gable panel 10. In other words, since spacers 20 are attached to the four corners of the gable panel 10, the building panels, which are stacked flat, can be temporarily placed in a stable position.

[0046] Furthermore, in the gable panel 10 of this embodiment, the spacer 20 has one longitudinal end (left end or right end) that protrudes outward from the side end face (left end face or right end face) of the panel body 11. In other words, the spacer 20 is attached to the gable panel 10 with a protruding portion 21 that extends outward from the gable panel 10. Therefore, since the spacer 20 is attached to the gable panel 10 with the protruding portion 21 provided, it not only prevents damage to the building panel during temporary placement, but also functions as a marker to confirm whether or not it is a gable panel 10 (a building panel having a connecting portion 14), and as a marker to confirm that the building panel is placed in the correct position on the lintel R.

[0047] Furthermore, in the gable panel 10 of this embodiment, the spacer 20 is fixed to the panel body 11 using nails N at both of its longitudinal ends (left end and right end). In other words, the spacer 20 is fastened to the gable panel 10 at two points using nails N. Therefore, the spacer 20 can be removed from the gable panel 10 simply by striking the protruding portion 21 of the spacer 20 from above with a hammer H. Furthermore, the lever principle comes into play, allowing the spacer 20 to be removed with little force, thus making the removal of the spacer 20 an efficient task.

[0048] Furthermore, in the gable panel 10 of this embodiment, the gable panel 10 is temporarily placed in an integral state with other building panels (roof panels 1a other than the gable panel 10) that do not have protruding parts such as connecting parts 14, and the spacer 20 is also removably fixed to the other building panels. Therefore, when temporarily placed, building panels positioned above the gable panel 10 can be supported not only by the connecting portion 14 and the spacers 20 attached to the gable panel 10, but also by the spacers 20 attached to the roof panel 1a which is integrated with the gable panel 10. As a result, even when the gable panel 10 is temporarily placed in an integrated state with other roof panels 1a, the load will not be concentrated on a predetermined part of the gable panel 10 (for example, the connecting portion 14), and damage to that predetermined part during temporary placement can be prevented.

[0049] Furthermore, the roof panel 1a, which is integrated with the gable panel 10, may be fixed to the gable panel 10 so that it can be separated from the gable panel 10 at the construction site. In other words, it may be integrated while being transported from the factory to the construction site or while being temporarily stored in a material storage area at the construction site, and may be separated when used at the construction site. Furthermore, the gable panel 10 does not necessarily have to be temporarily placed in an integrated state with the other roof panels 1a. In other words, the gable panel 10 may be temporarily placed on its own. In that case, the spacer 20 may be attached only to the gable panel 10 placed at the bottom.

[0050] Furthermore, the gable panel 10 of this embodiment is an architectural panel that constitutes the gable of a roof, and comprises a panel body 11 and a gable base material 12 fixed to the panel body 11. The connecting portion 14 is provided on the gable base material 12, and the soffit material 30 is fixed to the panel body 11 via the gable base material 12. In this embodiment, the gable panel 10 is fitted with a spacer 20, so that when temporarily placed, the building panel positioned above the gable panel 10 can be supported not only by the connecting portion 14 of the gable base material 12 but also by the spacer 20. Therefore, even when temporarily placed with the gable base material 12 fixed to the panel body 11, the gable base material 12 (especially the connecting portion 14) will not be damaged, and the installation work of the building panel can be carried out without any trouble. In other words, for example, when using a gable panel 10, if the gable base material 12 is attached to the panel body 11 at the construction site to construct the gable panel 10, damage to the gable panel 10 during temporary placement can be prevented. However, in that case, the gable base material 12 must be attached to the panel body 11 during the installation work of the building panel (when using the gable panel 10), which is time-consuming. In contrast, by attaching the spacer 20 as in this embodiment, even if the gable base material 12 is attached to the panel body 11 at the factory to construct the gable panel 10, damage to the gable panel 10 during temporary placement can be prevented. Therefore, by attaching the spacer 20, the gable base material 12 can be attached to the panel body 11 at the factory, so the installation work of the building panel can be carried out at the construction site without any extra effort.

[0051] Furthermore, the gable panel 10 in this embodiment is a building panel that is placed at the bottom during temporary placement. Therefore, when temporarily placed, the entire stack of building panels can be supported not only by the connecting portion 14 but also by the spacer 20, preventing the load from concentrating on a predetermined part (for example, the connecting portion 14) of the building panel placed on the bottom row, thus preventing damage to that predetermined part during temporary placement. Furthermore, the building panel placed at the bottom during temporary placement, i.e., the building panel to which the spacer 20 is attached, is not limited to the gable panel 10, but may be other building panels (wall panel 1b, floor panel, roof panel 1a other than the gable panel 10). Furthermore, in this embodiment, the spacer 20 is attached to the building panel placed in the bottom row during temporary placement, but this is not the only option. The building panel to which the spacer 20 is attached may be the building panel placed in the bottom row during temporary placement, or it may be a building panel placed in any position other than the bottom or top row during temporary placement, or it may be a building panel placed in the top row during temporary placement. Therefore, for example, the spacer 20 may be attached to all of the building panels in a flat stacked state.

[0052] Furthermore, the building panel in this embodiment is a wood-based panel. 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 achieve virtually zero carbon dioxide emissions, and for the achievement of the Sustainable Development Goals (SDGs). In the construction industry, efforts are underway to use wood, which reduces carbon dioxide emissions, for buildings. Buildings constructed with the building panels of this embodiment can be made of wood in part or all, thus contributing to the realization of a decarbonized society through the promotion of carbon neutrality and the achievement of the SDGs.
