In FIGS. 8 and 9, broken line frames indicate construction work, and solid line frames indicate mechanical / electrical equipment work.

The partition wall construction method according to the embodiment of the present invention is performed in the following procedure.
(1) The concrete of the floor slab 12 on the upper floor is placed, and after the curing period has elapsed, the disassembly work of the formwork 16 and the support work 17 is performed on the lower floor (in particular, FIG. 4, FIG. 8 and FIG. 9).

(2) An anchor bolt 18 is embedded at a position corresponding to the round hole 5 on the lower surface of the floor slab 12 on the upper floor, using the reference ink drawn on the floor slab 11 on the lower floor. Bolts and nuts 24 are screwed into the anchor bolts 18 through the round holes 5 to fix the wall-penetrating sleeve unit 1 to the lower surface of the floor slab 11 (particularly, refer to the lower flow in FIGS. 5, 8, and 9). ).

(3) Using the ink marking for the partition wall 10 drawn on the floor slab 11 on the lower floor, the duct 19 penetrating the sleeve 4 of the wall penetration sleeve unit 1 and the piping 20 are suspended. Further, the section 19 through which the duct 19 or the pipe 20 penetrates the sleeve 4 is filled with rock wool 25 (see FIG. 2) to perform the partition penetration process, and if necessary, the duct 19 and the pipe 20 are filled with glass wool 26 (see FIG. 2). (Refer to the lower flow of FIGS. 6, 8, and 9).

(4) From the area where the water stop measures on the upper floor have been completed, the lightweight steel frame that is the base material of the partition wall 10 using the ink marking for the partition wall 10 drawn on the floor slab 11 on the lower floor ( LGS) 14 is built. At this time, the lower end member 2b of the frame body 2 is brought into contact with the upper end of the light steel frame (LGS) 14 from below, and the left side member 2c and the right side member 2d of the frame body 2 are lightened from the side. By constructing so that the side surfaces of 14 are brought into contact with each other, a lightweight steel frame (LGS) 14 can be easily built together with the wall penetration sleeve unit 1 (particularly, the lower side of FIGS. 7, 8 and 9). Refer to the flow of

(5) The gypsum board 15 which is a board material is attached to the lightweight steel frame (LGS) 14 from both sides (particularly, refer to the lower flow in FIGS. 1, 8 and 9).

  As described above, according to the partition wall construction method according to the embodiment of the present invention, after disassembling the formwork 16 such as the floor slab 12 on the upper floor and the support work 17, wait until the water stoppage on the upper floor is completed. There is no (during the work period of the water stoppage on the upper floor), and on the lower floor, it is possible to construct the facility work prior to the construction of the partition wall 10, so that the construction period can be shortened. In addition, it is necessary to adjust the left and right lengths of the wall-penetrating sleeve unit 1 to an integral multiple of the built-in pitch width (usually 450 mm) of the lightweight steel frame (LGS), and the lightweight steel frame (LGS) at the left and right ends of the sleeve unit. Since there is no need to perform additional reinforcement, there is no need to restrict the arrangement of the duct 19 and the pipe 20, or it is not necessary to increase the left and right lengths of the frame body 2 more than necessary.

Therefore, work processes and man-hours can be reduced, and the occurrence of construction errors can be suppressed. Furthermore, generation | occurrence | production of industrial wastes, such as a lightweight steel frame (LGS) 14 and the gypsum board 15, can be suppressed, and reduction of conveyance work can be aimed at.

  Further, since the width of the lower member 2b, the left member 2c, and the right member 2d of the frame 2 is set to be larger than the thickness of the partition wall 10, even if a slight construction error occurs, a lightweight steel frame ( The frame body 2 can be used as a ruler when the LGS) 14 is installed and when the gypsum board 15 is attached. Therefore, the workability of the interior work can be further improved.

For example, assuming that the ceiling air conditioning work is performed on a 3000 m ² floor having 90 beds, the conventional construction method is expected to require 800 artificial workers for the air conditioning work. Thus, according to the construction method of the present invention, the same air conditioning equipment construction can be carried out by 614 artificial workers, and a trial calculation result that 186 artificial man-hours can be reduced can be obtained. Furthermore, it was possible to obtain a trial calculation result that the construction period could be shortened by about 4 to 5 weeks per floor.
