Description

The present invention relates to a panel loading rack and a panel installation method, and in particular to a panel loading rack and a panel installation method used to load architectural panels and lift the loaded architectural panels toward the main body of a building.

2. Description of the Related Art Loading racks capable of loading building panels of different widths and thicknesses manufactured in a factory for transporting the building panels have been known (see, for example, Patent Documents 1 and 2).
To explain the specific loading and transportation method, architectural panels (e.g., eaves panels and exterior wall panels) immediately after being removed from the manufacturing line in the factory are stored in the factory while being horizontally loaded on a loading rack. Then, they are loaded horizontally on the loading rack onto a transport vehicle such as a truck and transported to the construction site.
The transported building panels are unloaded together with the loading rack by a tow truck or the like installed at the construction site and stored at the construction site. Then, they are lifted one by one by a crane or the like installed at the construction site and attached to the designated parts of the building body.

By the way, when using the loading racks as described in Patent Documents 1 and 2, workers can efficiently work during loading and transporting operations from a factory to a construction site. However, when attaching architectural panels to a building body at a construction site, the architectural panels are generally directly lifted up by a crane or the like, and there is a risk that the finishing surface material of the architectural panel may be damaged or broken if the architectural panel comes into contact with other architectural members during the lifting operation.
Therefore, there was a need for technology that could improve the efficiency of loading and transporting architectural panels, as well as enable the architectural panels to be lifted stably and then efficiently attached to the main building body.
In particular, among various types of architectural panels, there was a demand for technology that could prevent damage, breakage, etc. to finishing surface materials in architectural panels such as eave panels, which have finishing surface materials fixed to the top surface, front side surface, and both side surfaces of a plate-shaped panel frame.

In addition, generally, when architectural panels are loaded and transported, in order to avoid damaging or breaking the finishing surface material, they are loaded and transported without the finishing surface material fixed to the panel frame, and then the architectural panel is completed by fixing the finishing surface material to the panel frame at the construction site.
However, in order to make the loading and transporting of architectural panels more efficient, there was a demand for technology that would allow the architectural panels to be completed in advance at a factory, and then load and transport the completed architectural panels while minimizing damage and breakage to the finishing surface materials.

The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a panel loading rack and a panel construction method that enable efficient loading, transporting, and lifting of architectural panels.
Another object of the present invention is to provide a panel loading rack and a panel installation method that can stably lift architectural panels and stably install the lifted architectural panels on the main body of a building.

The above-mentioned problem is solved by the panel loading rack of the present invention, which is a panel loading rack used for loading architectural panels and lifting the loaded architectural panels toward a predetermined portion of a building body, and includes a panel receiving member that supports the architectural panels from below, and a panel holding member that is attached to the panel receiving member and holds the architectural panels in a state in which a gap is formed between the architectural panels and the panel receiving member in the vertical direction when the architectural panels are loaded, and the panel receiving member is provided with a rack lifting device for lifting the panel loading rack by a lifting device. The problem is solved by providing a lifting portion, the panel holding member abutting the bottom surface of the architectural panel when the architectural panel is loaded and positioned so as to be hidden by the architectural panel in a plan view, and holding the architectural panel from below, the panel loading rack loading the architectural panel so that the side portions of the architectural panel protrude outward from the panel receiving member , and fixing the fixed portions provided on the bottom surface of the architectural panel to the panel fixing portions of the panel holding member from above and below with fixing members, whereby the panel holding member holds the architectural panel .
With the above configuration, a panel loading rack can be realized that enables efficient loading, transportation, and lifting of construction panels.
In more detail, when attaching an architectural panel to a designated location on the main building body, the architectural panel is not directly lifted by a lifting device, but the panel loading rack on which the architectural panels are loaded is lifted, so that the architectural panel can be lifted stably and the lifted architectural panel can be efficiently installed on the main building body.
In addition, since the panel holding member that holds the architectural panels while forming a gap between the loaded architectural panels and the panel receiving member in the vertical direction is provided, architectural panels having a finishing surface material can be loaded and transported efficiently. In other words, the architectural panels can be completed in advance at the factory, and the completed architectural panels can be loaded and transported while minimizing damage and breakage of the finishing surface material.

In addition , the panel holding member has a bottom wall portion attached to the upper surface of the panel receiving member, a side wall portion extending upward from the bottom wall portion, and an upper wall portion bent from the side wall portion and facing the bottom wall portion, and the panel fixing portion is formed on the upper wall portion, and the panel holding member holds the architectural panel by fixing the fixed portion of the architectural panel to the panel fixing portion with the fixing bolt.

At this time, the architectural panels are stacked horizontally, and the stacked architectural panels are lifted horizontally as they are toward a predetermined portion of the building body, and are installed from above and below in a horizontal state. The panel receiving member has a pair of support pillars that are spaced apart so as to sandwich the architectural panels and extend in the vertical direction, and a panel receiving portion that extends to connect the pair of support pillars and supports the architectural panels from below. The panel holding member is attached to the upper surface of the panel receiving portion and is spaced apart in the longitudinal direction of the panel receiving portion. The rack lifting section is provided on the upper portion of the support column, the panel receiving members are provided in a pair at a predetermined interval, and further includes a pair of connecting members that connect the pair of panel receiving members and are provided at a distance to sandwich the building panels, the connecting members being positioned below the building panels when the building panels are loaded, and the panel receiving members are preferably provided detachably from each other at a distance that allows the building panels to be horizontally accommodated when multiple panel receiving members are stacked vertically .
With the above configuration, a panel loading rack is provided that can efficiently perform the lifting work of architectural panels, such as eaves panels, which are loaded horizontally and lifted horizontally toward a specified part of the building body.
In addition, since the panel holding members are arranged at intervals in the longitudinal direction of the panel receiving portion and the rack lifting portion is provided in the upper portion of the support portion, the architectural panels can be loaded, transported, and lifted more stably.
Furthermore , architectural panels, such as eaves panels, which are installed horizontally from above and below at specific locations on the main body of a building, can be stably lifted and efficiently installed.
In addition, since the connecting members are disposed at a position lower than the loaded building panels, for example, when the panel loading rack on which the building panels are loaded is lifted and transported by a forklift or the like, it is possible to prevent the forklift (fork portion) from contacting the bottom surface of the building panels. In other words, the connecting members function as contact members that contact the forklift (fork portion).
In addition, a plurality of construction panels can be loaded vertically on the panel loading rack, and by dividing the panel loading rack, the construction panels can be lifted efficiently one by one.

The problem is also solved by a panel construction method that utilizes a panel loading rack used for loading architectural panels and lifting the loaded architectural panels toward a predetermined portion of a building body, the method including a panel loading step of loading the architectural panels onto the panel loading rack having a panel receiving member that supports the architectural panels from below and a panel holding member that holds the architectural panels; a panel lifting step of attaching a part of a lifting device to a rack lifting section provided on the panel receiving member and lifting at least a part of the panel loading rack holding the architectural panels toward a predetermined portion of the building body; and a panel installation step of installing the architectural panels in a loaded state at the predetermined portion of the building body. and a panel removal process of removing the installed architectural panel from the panel loading rack, in which in the panel loading process, the architectural panel is held from below with the panel holding member forming a gap between the architectural panel and the panel receiving member in the vertical direction, the panel holding member is abutted against the bottom surface of the architectural panel and positioned so as to be hidden by the architectural panel in a plan view, and the architectural panel is loaded so that a side portion of the architectural panel protrudes outward from the panel receiving member, and in the panel loading process, the architectural panel is held by fixing a fixed portion provided on the bottom surface of the architectural panel to the panel holding member from the vertical direction with a fixing member .

In this case, in the panel loading process, the building panels are loaded horizontally, in the panel lifting process, the panel loading rack is lifted horizontally toward a designated portion of the building body, and in the panel installation process, the building panels are installed in a horizontal state from the vertical direction at a designated portion of the building body so that the panel receiving member and the designated portion of the building body do not overlap in the vertical direction.
With the above configuration, architectural panels, such as eaves panels, which are loaded horizontally, lifted horizontally toward the main building body, and installed horizontally from above and below at designated locations on the main building body, can be constructed efficiently and stably.
In addition, when installing the architectural panel at a designated portion of the building body, interference between the panel receiving member and the designated portion of the building body in the vertical direction can be prevented, allowing the architectural panel to be installed efficiently and stably.

In this case, the panel construction method is used to construct the architectural panel having a finishing surface material fixed to the side of a plate-shaped panel frame, and in the panel loading process, the architectural panel is held by fixing the fixed portion provided on the bottom surface of the panel frame to the panel holding member from above and below, and in the panel installation process, the architectural panel is installed horizontally by fitting the panel frame into a predetermined portion of the building main body from above and below.
With the above-mentioned configuration, in an architectural panel having a finishing surface material, the architectural panel can be loaded, transported, lifted and installed while preventing damage and breakage of the finishing surface material as much as possible.

According to the panel loading rack and panel installation method of the present invention, loading, transporting and lifting operations of architectural panels can be carried out efficiently.
In addition, the architectural panel can be stably lifted, and the lifted architectural panel can be stably installed on the main body of the building.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 9A and 9B.
This embodiment is a panel construction method that utilizes a panel loading rack that is used to horizontally stack architectural panels and lift the loaded architectural panels horizontally toward a designated portion of the building body, and includes a panel loading process of loading architectural panels onto the panel loading rack, a panel lifting process of attaching a part of a lifting device to the rack lifting portion of the panel loading rack and lifting the architectural panels toward a designated portion of the building body, a panel installation process of installing the architectural panels in the loaded state at the designated portion of the building body, and a panel removal process of removing the installed architectural panels from the panel loading rack. This embodiment relates to an invention characterized in that in the panel loading process, the architectural panels are held by the panel holding member in a state in which a gap is formed between the architectural panel and the panel receiving member in the vertical direction.

The panel loading rack 1 of this embodiment, as shown in Figure 1, is a rack that is capable of transporting and storing multiple building panels 2 loaded thereon, and is used, for example, to store the building panels 2 in a horizontally loaded state in a factory, or to transport the building panels 2 from a factory to a construction site in a horizontally loaded state.
As shown in FIG. 2, the panel loading rack 1 is used to lift the loaded architectural panels 2 toward a designated location on the building body, and also to install the architectural panels 2 in the designated location from above and below while keeping them horizontal.

As shown in Figures 3A and 3B, the architectural panel 2 is a rectangular plate-shaped member that constitutes a building, and specifically, is a eaves panel that is mainly composed of a rectangular plate-shaped panel frame 2a and a rectangular plate-shaped finishing surface material 2b that is fixed to the top surface, front side surface, and left and right side surfaces of the panel frame 2a.
The finishing surface material 2b fixed to the side surface of the panel frame 2a is attached so as to protrude in the vertical direction (upward and downward) beyond the panel frame 2a.
Therefore, when loading the architectural panels 2, it is necessary to take measures to prevent the parts of the finishing surface material 2b protruding from the panel frames 2a from being damaged or broken.

Fixing nuts 2c, 2d for fixing to the panel loading rack 1 are formed on both ends in the width direction on the bottom surface of the panel frame 2a.
In addition, in the portion between the fixing nuts 2c and 2d on the bottom surface of the panel frame 2a, a plurality of cutout grooves 2e are formed at intervals for fitting into a predetermined portion of the building main body B shown in Figure 4 (specifically, the arm B1) from above and below.
In addition, the architectural panel 2 is not particularly limited to an "eaves panel", but may be a single-sided finished panel such as an "exterior wall panel" or a "roof panel", or a double-sided finished panel such as a "wain wall panel", and various types of architectural panels can be adopted.

As shown in Figure 1, the panel loading rack 1 is mainly composed of a pair of panel support members 10 that are arranged at a predetermined interval and support the architectural panel 2 from below, a pair of connecting members 20 that connect the pair of panel support members 10 and are arranged at a interval so as to sandwich the architectural panel 2, and a panel holding member 30 that is attached to the panel support members 10 and holds the architectural panel 2 while forming a gap between the architectural panel 2 and the panel support members 10 in the vertical direction.
The panel loading rack 1 of this embodiment is configured by stacking a pair of panel receiving members 10 vertically in three tiers. The first tier of the panel loading rack 1 is loaded with "long construction panels," the second tier is loaded with "medium construction panels," and the third tier is loaded with "long construction panels."
As shown in Figure 1, when multiple building panels 2 are loaded, the center portion of each building panel 2 in the width direction is located at the center portion of the panel loading rack 1 in the longitudinal direction, in other words, at the middle portion between a pair of panel receiving members 10.

As shown in Figures 1 and 5, the panel support member 10 is a support member for the architectural panel 2 and consists of a long, approximately H-shaped body processed from a metal square pipe or the like. In addition to functioning as the base for the panel loading rack 1, it also functions as a member for detachably supporting the architectural panel 2.
Two panel support members 10 are provided standing at a distance from each other to support both ends of the building panel 2 in the frontage direction from below.
Furthermore, the panel receiving members 10 can be stacked vertically at intervals sufficient to accommodate the building panels 2, and are configured to be detachable from one another.

The panel support member 10 is mainly composed of a pair of support pillars 11 that are spaced apart to sandwich the architectural panel 2 and extend in the vertical direction, and a panel support portion 12 that extends to connect the pair of support pillars 11 and supports the architectural panel 2 from below.
A plurality of panel holding members 30 are attached to the upper surface of the panel receiving portion 12 at intervals in the longitudinal direction of the panel receiving portion 12 .

As shown in FIG. 5 , the support portions 11 are portions which, when a plurality of panel receiving members 10 are stacked in the vertical direction, act as support portions of the panel loading rack 1 as a whole, and are disposed at the four corners of the panel loading rack 1 .
The support portion 11 has a main body portion 11a which is elongated in the vertical direction and has a U-shaped cross section, an engagement protrusion portion 11b formed at the upper end of the main body portion 11a, and an engagement hole portion 11c formed at the lower end of the main body portion 11a which detachably engages with the engagement protrusion portion 11b when multiple portions are stacked in the vertical direction.
In addition, the support portion 11 is formed to protrude from the outer surface of its main body portion 11a and has a connecting attachment axis 11d for attaching the connecting member 20, and a rack lifting hole 11e formed on the outer surface of the engaging protrusion portion 11b for lifting the panel loading rack 1 by a lifting device.

The connecting mounting axis 11d is a mounting axis that protrudes from the outer surface of the support portion 11 (main body portion 11a) on the side opposite the panel receiving portion 12, and is positioned at a higher position than the panel receiving portion 12 in the height direction of the panel loading rack 1, and is positioned at approximately the same height as the panel holding member 30.
The rack lifting holes 11e are through holes for attaching the ends of the wires L2 hooked onto the lifting device L (lifting hooks L1) shown in FIG. 2, and are disposed at the four corners of the panel loading rack.
More specifically, the rack lifting hole 11e penetrates the outer and inner surfaces of the support column 11 (the engaging protrusion 11b) in a direction perpendicular to the extending direction of the support column 11.
In this embodiment, as shown in FIG. 2, two long sling wires L2 and shackles L3 are used to hoist the panel loading rack 1 horizontally, and the shackles L3 are attached so as to pass through the support portions 11.

The panel receiving portion 12 is a long body with a U-shaped cross section that supports the end portion of the building panel 2 in the frontage direction from below, and is located at both ends of the panel loading rack 1 in the longitudinal direction.
A panel holding member 30 for holding the building panels 2 stacked horizontally is attached to the upper surface of the panel receiving portion 12.

As shown in Figures 1 and 6, the connecting member 20 is a member that connects a pair of panel receiving members 10 and is made of a long, rectangular plate-shaped body. In addition to imparting rigidity to the panel loading rack 1 and holding the architectural panel 2 in place by clamping it, the connecting member 20 also functions as an abutment member against which the fork portion (claw portion) of a forklift or the like abuts when the panel loading rack 1 is lifted and transported by the forklift or the like.
At both ends in the longitudinal direction of the connecting member 20, mounting holes 21 for mounting to the connecting mounting shaft 11d of the support portion 11 are formed, and the connecting member 20 is fixed to the outer surface of the support portion 11.
At this time, the pair of connecting members 20 are configured to sandwich the panel receiving member 10 therebetween.

As shown in FIG. 6, at both ends of the connecting member 20 in the longitudinal direction, a generally T-shaped rack lifting section 22 is formed for engaging the sling wire L2 of the lifting device L. The rack lifting section 22 can also be used to lift the panel-loading rack 1.

As shown in Figure 7, the panel holding member 30 is a member that holds the architectural panel 2 from below, and is made of a plate-like member with an approximately U-shaped cross section, and is attached in a pair to both ends of the panel receiving member 10 (panel receiving portion 12) in the longitudinal direction.
In detail, the panel holding member 30 has a bottom wall portion 31 attached to the upper surface of the panel receiving portion 12, a side wall portion 32 extending upwardly continuously from the inner end portion of the bottom wall portion 31, and an upper wall portion 33 bent continuously from the extended end portion of the side wall portion 32 and extending outward in the width direction of the panel receiving portion 12.
A panel fixing hole 34 is formed by cutting out the outer edge of the upper wall portion 33 toward the center at the outer edge portion closest to the support portion 11 .

As shown in FIG. 7 , the panel fixing hole 34 is a cut-out hole having a substantially semi-elliptical shape, and the fixing bolt 35 can be introduced into the panel fixing hole 34 .
The panel fixing holes 34 are fastened by fixing bolts 35 in a state where they are vertically connected to fixing nuts 2c, 2d provided on the bottom surface of the building panel 2.
In this way, the construction panel 2 can be fixed to the panel loading rack 1.

In the above configuration, as shown in Figures 1 and 6, the connecting member 20 is positioned above the panel receiving portion 12 in the height direction of the panel loading rack 1, and is arranged to sandwich the building panel 2.
Therefore, the building panels 2 can be stably loaded and transported.
In addition, as shown in Figure 4, the panel loading rack 1 is used to lift the loaded architectural panels 2 toward a specified portion of the building body B, and can lift the architectural panels 2 stably.
In addition, the panel loading rack 1 is used when installing the lifted architectural panel 2 (eaves panel) in a horizontal position from above and below on a specified portion (arm B1) of the building main body B, and it is possible to prevent interference between the connecting member 20 and the arm B1 of the building main body B in the vertical direction, thereby enabling the architectural panel 2 to be installed stably.

In the above configuration, the panel loading rack 1 is provided with a rack lifting hole 11e as shown in Figs.
Therefore, the lifting device L shown in Figure 2 does not directly lift the architectural panel 2, but rather lifts the panel loading rack 1 on which the architectural panel 2 is loaded, so that the architectural panel 2 can be lifted efficiently and stably.
In the above configuration, the rack lifting hole 11 e is located above the panel holding member 30 and is located outside the panel holding member 30 in the short length direction of the panel loading rack 1 .
Therefore, the panel loading rack 1 has a shape and configuration that allows stable and easy lifting. As a result, the lifting work of the architectural panel 2, which is loaded horizontally and lifted horizontally toward a predetermined part of the building body, such as a eaves panel, can be performed stably and efficiently.

In addition, in the above configuration, the connecting member 20 is positioned at approximately the same height as the panel holding member 30 in the height direction of the panel loading rack 1, and is positioned lower than the architectural panel 2 (the lower end portion of the architectural panel 2).
This makes it possible to prevent the forklift (fork portion) from coming into contact with the bottom surface of the architectural panel 2 when the panel loading rack 1 loaded with the architectural panel 2 is lifted and transported by a forklift or the like.
In other words, when the architectural panel 2 is transported, it is possible to prevent the part of the finishing surface material 2b protruding from the panel frame 2a from being damaged.

In the above configuration, as shown in FIG. 4, the panel loading rack 1 is lifted together with the architectural panel 2, and is used when installing the lifted architectural panel 2 (eaves panel) in a horizontal state from above and below on the arm B1 of the building body B.
At this time, if the connecting members 20 are left attached to the panel loading rack 1, the connecting members 20 will interfere with the arms B1. Therefore, it is advisable to remove the connecting members 20 in advance before installing the construction panels 2 on the building body B, specifically before hoisting the panel loading rack 1.
This results in a panel loading rack 1 that can efficiently carry out a series of operations from loading and transporting the architectural panels 2 to lifting and installing them.

<Panel installation method>
Next, a panel installation method using the panel loading rack 1 will be described with reference to FIG.
Specifically, as shown in FIG. 4, a panel installation method will be described in which a panel loading rack 1 loaded with architectural panels 2 (eaves panels) is lifted horizontally toward the building body B, and the architectural panels 2 are then installed directly onto the arms B1 of the building body B from above and below.

As shown in FIG. 8, the panel installation method using the panel loading rack 1 starts with a rack assembling process (step S1) in which the panel loading rack 1 is assembled in a factory.
Specifically, a pair of panel receiving members 10 and connecting members 20 are stacked vertically as one unit to assemble the panel loading rack 1. For example, as shown in Fig. 1, a plurality of "long architectural panels" or "medium architectural panels" can be appropriately selected and loaded.

Thereafter, the building panels 2 are horizontally loaded on the panel loading rack 1 (step S2), and the building panels 2 are fixed to the panel holding members 30 on the panel receiving members 10 (step S3).
In the panel loading process, the building panels 2 are loaded so that both ends in the frontage direction of the building panels 2 are supported by a pair of panel receiving members 10.
In addition, by placing one building panel 2 each time a pair of panel receiving members 10 are installed at the same height position, multiple building panels 2 can be stacked with spacing between them in the vertical direction.
In the panel fixing process, the building panel 2 is fixed using a fixing bolt 35 with the panel fixing hole 34 of the panel holding member 30 communicating with the fixing nuts 2c, 2d provided on the building panel 2.
In addition, when the architectural panel 2 is fixed to the panel loading rack 1, a gap is formed between the architectural panel 2 and the panel receiving member 10 in the vertical direction, so that the finishing surface material 2b of the architectural panel 2 does not come into contact with other components.

Thereafter, the panel loading rack 1 loaded with the building panels 2 is transported to the construction site by a transport vehicle (step S4), the panel loading rack 1 is unloaded at the construction site, and the connecting members 20 are removed from the panel loading rack 1 and then stored at the construction site (step S5).
During storage, as shown in FIG. 9A(a), an arm B1 is installed on the building body B, and an exterior wall panel B2 is installed in the upper portion adjacent to the arm B1 (step S6).
Furthermore, by installing the exterior wall panel B2 at this stage, it becomes easier to ensure the safety of workers.

Then, a part of the lifting device L is attached to the rack lifting hole 11e of the panel loading rack 1, and the part of the panel loading rack 1 to which the building panel 2 is fixed is lifted horizontally toward the building main body B, as shown in Figure 9A (b) (step S7).
In this case, the part of the panel loading rack 1 refers to a pair of panel receiving members 10 and a pair of connecting members 20 located on the top tier of the panel loading rack 1 shown in Figure 1, and the building panel 2 refers to a long building panel located on the top tier.

Thereafter, as shown in FIG. 9A(c), the building panel 2 is vertically placed on the arm B1 of the building body B in a horizontal state and temporarily fixed thereto (step S8).
Specifically, the building panel 2 is installed horizontally so that the pair of panel receiving members 10 and the brackets B1 of the building body B do not overlap in the vertical direction.
More specifically, the panel frame 2a (notched groove 2e) of the architectural panel 2 is fitted from above into the arm B1, thereby temporarily fixing the architectural panel 2.

Thereafter, as shown in FIG. 9A(d), the construction panel 2 is removed from the panel loading rack 1 (step S9), and the construction panel 2 is finally fixed to the arm B1 of the building body B (step S10), thereby completing this work process.
In order to secure the architectural panel 2, the architectural panel 2 is slid along the arm B1 and pulled toward the building body B, and then the arm B1 and the architectural panel 2 are secured by bolts.
The above-described panel construction method not only facilitates loading and transporting of the architectural panel 2, but also enables the architectural panel 2 to be stably lifted and efficiently installed on the building body B.

In the above-mentioned work process, as shown in FIG. 9A, the exterior wall panel B2 is installed in advance before the architectural panel 2 (eaves panel) is installed on the building main body B, but this can be modified without any particular limitation.
For example, as shown in Fig. 9B, the exterior wall panel B2 may be installed after the architectural panel 2 is installed (temporarily fixed) to the building body B. In this case, a worker can install the exterior wall panel B2 while using the temporarily fixed architectural panel 2 as a scaffold.
When the construction method shown in FIG. 9B is adopted, step S6 in the panel construction method shown in FIG. 8 is changed to "install arms on the building body," and a new step S9-2, "installation of exterior wall panels," is added after step S9, "panel removal step."

<Other embodiments>
In the above embodiment, as shown in Figures 1 and 2, a panel loading rack 1 is described which is used to load architectural panels 2 (eaves panels) "horizontally" and lift the loaded architectural panels 2 "horizontally" toward the main body of the building, but this can be modified without any particular limitation.
For example, a panel loading rack may be used to load building panels (exterior wall panels) "vertically" and lift the building panels "vertically" toward the building body.
In this case, the architectural panel may be installed vertically at a predetermined location on the main body of the building from the side.
For example, the panel loading rack may be used when loading architectural panels (roof panels) at an angle and lifting the architectural panels at an angle toward the main body of the building.
In this case, the architectural panel may be installed at an angle from the outside at a given position on the main body of the building.

In the above embodiment, as shown in FIG. 1, the panel loading rack 1 includes a pair of panel receiving members 10 and a pair of connecting members 20, but this is not particularly limited and can be modified.
For example, the panel loading rack may be provided with only one panel receiving member that is formed wider than the panel receiving member 10, and the building panel 2 may be supported by the panel receiving member.
For example, the panel loading rack may be configured to include a pair of panel receiving members 10 and one connecting member.
Also, for example, the panel loading rack may be configured to include one panel holding member 30 on each of the upper surfaces of a pair of panel receiving members 10, or may be configured to include three or more panel holding members 30 on each of the upper surfaces.

In the above embodiment, as shown in Figure 5, the engagement protrusion 11b of the panel receiving member 10 is formed at the upper end of the support portion 11, and the engagement hole portion 11c is formed at the lower end of the support portion 11, but this can be changed without being particularly limited, and the configuration may be reversed.
That is, the engagement hole 11c may be formed at the upper end of the support 11, and the engagement protrusion 11b may be formed at the lower end of the support 11.
In addition, the engagement relationship between the projection and the hole does not have to be particularly limited. That is, the support 11 may have a first engagement portion formed at its upper end and a second engagement portion formed at its lower end, which detachably engages with the first engagement portion when the support 11 is stacked in multiple positions in the vertical direction.

In the above embodiment, the panel loading rack and the panel installation method according to the present invention have been mainly described.
However, the above embodiment is merely an example for facilitating understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof.
