The mechanism 24 is arranged. As a result, as shown in FIG. 3B, the horizontal position of the eaves ceiling panel 6 mounted on the panel support mechanism 23 can be finely adjusted with respect to the elevating mechanism 22.

The roof 3 of the outdoor stadium 100 can be constructed by the following procedure by the work stage 10 and the panel lifting device 20 having the above-described configuration.

That is, after the roof skeleton 5 is constructed, the work stage 10 is assembled below the roof skeleton 5, and the panel lifting device 20 is mounted on the work stage 10. After that, the eaves ceiling panel 6 is pushed up to the vicinity of the lower surface of the roof skeleton 5 via the panel lifting device 20 on the work stage 10, and fine adjustments are made in the horizontal and height directions as necessary. The top panel 6 is positioned at the planned installation position of the roof skeleton 5, and is temporarily fixed to the roof skeleton 5. The work of installing the roof finishing material 7 on the upper surface of the roof frame 5 may be carried out at the same time as the work of installing the eaves ceiling panel 6 described above, or may be carried out in advance.

In such a roof construction method, the details of the installation work of the eaves ceiling panel 6 are given as an example in which the roof frame 5 is divided into a plurality of construction zones and carried out for each construction zone, and according to the flow chart shown in FIG. explain. In the present embodiment, the roof skeleton 5 is arranged so as to cover only a part of the area of the stand 2, but the roof frame 5 is not necessarily limited to this, and the entire stand 2 is used. The roof 3 may be constructed so as to cover the roof 3.

(First step: step1)
First, as shown in FIG. 2, a fixed stage S is constructed on the inner peripheral side of the stand 2, and then the working stage 10 is assembled so as to be supported by the fixed stage S and the stand skeleton 21.

(First step: step2)
As shown in FIG. 5, the roof skeleton 5 is divided into a plurality of work areas in the circumferential direction of the stand 2, and then the work stage 10 assembled as described above is arranged in the area corresponding to the first work area A. ..

(Second step: step3)
As shown in FIG. 2, after moving the panel lifting device 20 to the overhanging floor 15 of the work stage 10, the eaves panel 6 grounded in the ground yard Y is loaded by the large lifting machine M. , It is placed on the panel support mechanism 23 of the panel lifting device 20.

At this time, the panel support mechanism 23 of the panel lifting device 20 is provided with a plurality of attitude control mechanisms 231 so that the eaves ceiling panel 6 can be placed while maintaining the installation posture when it is installed on the roof frame 5. Adjust the length of each column.

(Second step: step4)
As shown in FIG. 6, when the panel lifting device 20 is run to convey the eaves panel 6 to just below the planned installation position on the roof skeleton 5, and the eaves ceiling panel 6 is installed on the roof skeleton 5. Match the orientation of.

Here, for example, as shown in FIG. 3B, the panel lifting device 20 is provided with the terminal device 25. The terminal device 25 is a so-called notebook personal computer or tablet terminal provided with an arithmetic processing unit 251, an input unit 252, a display unit 253, a storage unit 254, and the like. The arithmetic processing device 251 is a computer having a CPU, GPU, ROM, RAM, a hardware interface, and the like. The input unit 252 is an input device such as a switch and a keyboard. The display unit 253 is a display that displays a screen. The storage unit 254 is a storage device including a semiconductor memory, a hard disk drive, or the like, and stores a program that can be executed by the arithmetic processing unit 251.

Then, the position of the center of gravity and the azimuth of the eaves panel 6 to be installed are grasped from the BIM data storing the information such as the design drawing of the roof 3, and stored in the storage unit 254 of the terminal device 25. Further, the shape of the lower surface of the roof skeleton 5 is stored in the storage unit 254 of the terminal device 25 as a point cloud model composed of point cloud data on the world coordinate system, and the eaves ceiling panel 6 is installed in the roof skeleton 5. The position of the center of gravity and the azimuth angle at that time are calculated by the arithmetic processing device 251 and stored in the storage unit 254.

On the other hand, the position of the center of gravity of the panel lifting device 20 in which the eaves ceiling panel 6 is placed is grasped by measurement by a total station. Then, based on the information on the planned installation position of the eaves panel 6 stored in the storage unit 254 of the terminal device 25 and the information on the position of the center of gravity of the panel lifting device 20, the state of being mounted on the panel lifting device 20. The position of the center of gravity of the eaves panel 6 can be moved on the same vertical line as the position of the center of gravity of the planned installation position of the roof skeleton 5, and the azimuth angle is the same as the azimuth angle when the roof skeleton 5 is installed. Can be matched.

For an apparatus and method for grasping the shape of the lower surface of the roof skeleton 5 as a point cloud model composed of point cloud data on the world coordinate system, refer to Japanese Patent Application No. 2016-034256, for example.

After that, the elevating mechanism 22 of the panel lifting device 20 pushes the eaves ceiling panel 6 toward the lower surface of the roof skeleton 5 to a predetermined height. When it is necessary to make fine adjustments to the horizontal position and height position of the eaves ceiling panel 6, the positions are finely adjusted by using the horizontal adjustment mechanism 24 and the level adjustment mechanism 232 of the panel lifting device 20 described above. In this way, the eaves ceiling panel 6 is positioned at the planned installation position of the roof frame 5, and both are temporarily fixed via temporary fixing means (not shown).

(Second step: step5)
The above steps 3 and 4 are repeated until the eaves panel 6 is installed in all the areas corresponding to the first construction zone A in the roof frame 5.

(Third step: steps 6 and step 2)
As shown in FIG. 7, after the eaves ceiling panel 6 has been installed in all the areas corresponding to the first work area A, the work stage 10 is moved to the next work area.

(Fourth step: steps 6 and 7)
The second step and the third step are repeated until all of the plurality of divided construction sections are reached, and as shown in FIG. 1, the eaves ceiling panels 6 are installed on all the lower surfaces of the roof skeleton 5. After these are completed, the work stage 10 is disassembled.

According to the roof construction method of the present invention, the eaves ceiling panel 6 is made into a roof skeleton by using the work stage 10 arranged below the roof skeleton 5 and the panel lifting device 20 running on the work stage 10. It can be installed from below 5. As a result, the work of installing the roof finishing material 7 on the upper surface of the roof frame 5 can be carried out at the same time as or in advance of the work of attaching the eaves ceiling panel 6, and the like for installing the eaves ceiling panel 6. Interference between the work space and other work spaces related to the construction of the roof can be minimized, and the construction work of the roof 3 can be carried out quickly.

Further, since the eaves ceiling panel 6 can be aligned with the roof frame 5 by the panel lifting device 20 without human power, the eaves ceiling panel in a state of being suspended by a large lifting machine M such as a crane as in the conventional case. No complicated work such as aligning 6 with respect to the roof skeleton 5 occurs. Therefore, it is safe and the work efficiency can be significantly improved. Further, since the roof skeleton 5 does not require an opening, the eaves ceiling panel 6 can be easily installed on the roof skeleton 5 having any structure.

Further, since the roof frame 5 can be divided into a plurality of construction zones and the eaves ceiling panel 6 can be installed in each construction zone, it is not necessary to provide a large-scale work stage 10 at the site, which saves space and is economical. It becomes possible to carry out the construction work of.
