In addition, the building unit 1 shown by FIGS. 18-21 is the 1st building unit 10 which comprises the first floor of a building. Below, the example in which the jig | tool 200 and the ceiling panel 100 are installed in the building unit 1 as the 1st building unit 10 is demonstrated. The description when the jig 200 and the ceiling panel 100 are installed in the second building unit 20 is the same as that of the first building unit 10 and will be omitted.

When the jig 200 and the ceiling panel 100 are suspended, the ceiling panel 100 is fitted into the inside of the wall 15 of the building unit 1 from above, and the jig 200 is placed on the column 12 and the wall 15 of the building unit 1. . Specifically, the rectangular frame portion 201 of the jig 200 is placed on the upper end surface 12 b of the column 12 located at the ceiling portion of the building unit 1.
As shown in FIG. 20, at least some of the pillars 12 of the building unit 1 have an upper engagement hole 12c extending in the axial direction on the upper end surface 12b. All the columns 12 may have the upper engagement holes 12c. The rectangular frame portion 201 of the jig 200 has a through hole 201e at a position aligned with each of the upper engagement holes 12c of the pillar 12 when the building unit 1 is installed in a predetermined arrangement. Each through-hole 201e extends in the vertical direction substantially perpendicular to the extending direction of the linear members 201a to 201d of the rectangular frame 201. Here, the through hole 201e is an example of the alignment portion and the first hole, and the upper engagement hole 12c is an example of the second hole.

Furthermore, as shown in FIG. 25, the rectangular frame 102a is fastened to the guide fitting 2205 with a joining fitting such as a screw or a nail.

Next, as shown in FIG. 26, installation of the ceiling material 104 on the base plate material 103 (step S205) is performed. FIG. 26 is a perspective view showing a state in which the ceiling material 104 is installed on the base plate material 103 of the ceiling panel 100 of FIG.
Further, the ceiling panel 100 and the jig 2200 after the installation of the ceiling material 104 are turned upside down together (step S206). Furthermore, a plurality of suspenders 2206 for connecting the ceiling panel 100 and the jig 2200 are installed (step S207). After installation of the hanger 2206, all the guide fittings 2205 are removed from the jig 2200 and the ceiling panel 100. The guide fitting 2205 may be simply removed from the ceiling panel 100. Thereafter, as shown in FIG. 27, the jig 2200 is lifted together with the ceiling panel 100 in order to install the ceiling panel 100 on the building unit 1 (step S208). FIG. 27 is a perspective view showing a state of the jig 2200 lifted after being inverted up and down together with the ceiling panel 100 of FIG. Then, the underlay board | plate material 101 arrange | positioned on the ceiling panel 100 is removed (process S209).

  Referring to FIGS. 27 and 28, in the present embodiment, six suspension members 2206 having rigidity are arranged on the linear members 201a and 201c of the rectangular frame portion 201 of the jig 2200. Specifically, three hanging tools 2206 are arranged on the linear members 201a and 201c, respectively. FIG. 28 is an enlarged perspective view showing the suspension tool 2206 in a state where the ceiling panel 100 of FIG. 27 is suspended from the jig 2200.

  Each suspension tool 2206 includes a shaft member 2206a having a male screw formed on the outer peripheral surface, an insertion member 2206b having a hole through which the shaft member 2206a can be inserted and fixed to the outer peripheral side surface 201g of the linear member 201a or 201c. The locking member 2206c and the fixing member 2206d each have a female screw hole that can be screwed with the male screw of the shaft member 2206a, and a plate-like holding member 2206e that holds the ceiling panel 100. For example, the shaft member 2206a is a member having rigidity such as a long screw, and the locking member 2206c and the fixing member 2206d are fastening members such as a hexagon nut. The shaft member 2206a extends in the vertical direction through the hole of the insertion member 2206b. The lower portion of the shaft member 2206a extends through the holding member 2206e, and is connected and fixed to the holding member 2206e by two fixing members 2206d that screw into the shaft member 2206a and sandwich the holding member 2206e. . The holding member 2206e can engage with the ceiling panel 100 from below and hold the ceiling panel 100. The locking member 2206c is screwed to the shaft member 2206a at the upper part opposite to the fixing member 2206d with respect to the insertion member 2206b. The locking member 2206c restricts the downward sliding movement of the shaft member 2206a relative to the insertion member 2206b. In addition, since the jig 2200 is connected to the ceiling panel 100 via a plurality of suspension tools 2206 having high rigidity, relative movement in the horizontal direction between the jig 2200 and the ceiling panel 100 is suppressed.

  Therefore, when the jig 2200 is lifted via the hanging bracket 204 in step S208, the jig 2200 moves relative to the ceiling panel 100 in a direction away from the ceiling panel 100 while sliding the insertion member 2206b along the shaft member 2206a of the hanging tool 2206. . When the insertion member 2206b comes into contact with the locking member 2206c, the jig 2200 is separated from the jig 2200 through the insertion member 2206b, the locking member 2206c, the shaft member 2206a, the holding member 2206e, and the like. Suspend. In addition, the holding member 2206e of the hanger 2206 in the position which opposes on both sides of the ceiling panel 100 may be mutually connected and integrated. Thereby, the holding member 2206e extends so as to cross the ceiling panel 100, and the ceiling panel 100 can be stably held.

The following description relates to installation of the jig 2200 and the ceiling panel 100 to the building unit 1 as the first building unit 10. Since the description regarding installation of the jig 2200 and the ceiling panel 100 to the second building unit 20 is the same as that of the first building unit 10, a description thereof will be omitted.

  The jig 2200 is fitted inside the plurality of pillars 12 of the building unit 1 together with the ceiling panel 100 from above. Furthermore, the jig 2200 is fixed to these columns 12 by engaging and fixing the plurality of engaging members 2207 to the plurality of columns 12 from the inside. In the rectangular frame portion 201 of the jig 2200, engaging members 2207 are arranged at positions corresponding to the plurality of pillars 12 when the building unit 1 is installed in a predetermined arrangement.

  As shown in FIG. 30, one engagement member 2207 is arranged for one pillar 12 located at the corner of the building unit 1. In this case, the engaging member 2207 forms an L-shaped groove-shaped first recess 2207b that extends in the vertical direction and opens outward in the lateral direction between the contact surface 2207a and the outer peripheral side surface 201g of the rectangular frame 201. . The rectangular frame portion 201 is disposed so that the upper portion of the column 12 is fitted into the first recess 2207 b and the outer peripheral side surface 201 g and the contact surface 2207 a are brought into contact with the two side surfaces of the column 12. Furthermore, the rectangular frame portion 201 is fixed to the column 12 by fastening the engaging member 2207 to the column 12 using a joint fitting such as a screw or a nail.

  As shown in FIG. 31, two engagement members 2207 are arranged for one column 12 located between corners of the building unit 1. In this case, the two engaging members 2207 extend in the vertical direction between the two contact surfaces 2207a and the outer peripheral side surface 201g of the rectangular frame portion 201, and are opened in a U-shaped groove shape. A recess 2207c is formed. The rectangular frame portion 201 is disposed so that the upper portion of the column 12 is fitted into the second recess 2207 c and the outer peripheral side surface 201 g and the two contact surfaces 2207 a are brought into contact with the three side surfaces of the column 12. Further, the two engaging members 2207 are fastened to the pillar 12, whereby the rectangular frame portion 201 is fixed to the pillar 12.

  As described above, the plurality of engaging members 2207 of the jig 2200 are fixed to the plurality of pillars 12 of the building unit 1 so that the cross-sectional shape of the building unit 1 formed by the plurality of pillars 12 is the plurality of engaging members. It is shaped into a predetermined cross-sectional shape that is a shape defined by the array 2207 and the outer peripheral side surface 201 g of the rectangular frame 201. That is, the pillar 12 is positioned so as to form a predetermined cross-sectional shape defined by the rectangular frame portion 201. As a result, the ceiling panel 100 fits closely inside the wall of the building unit 1 in a predetermined horizontal posture.

In addition, as shown in FIG. 30, the distance between the jig 2200 and the ceiling panel 100 can be adjusted by adjusting the distance between the locking member 2206 c and the holding member 2206 e in the hanger 2206. Therefore, the height position of the ceiling panel 100 with respect to the column 12 can be adjusted. Moreover, since the ceiling panel 100 suspended from the jig 2200 can be positioned below the upper end of the pillar 12, a space behind the ceiling can be secured.
In addition, although the building unit 1 shown by FIG. 29 has the structure by which the pillar 12 was built on the base 11, it may have the structure by which the wall 15 was formed. In this case, it is only necessary that the plurality of engaging members 2207 of the jig 2200 can engage with the upper portion of the column 12.

After completing the fixing of the jig 2200, the ceiling panel 100 is fixed to the building unit 1 (step S211). Specifically, the frame member 102 of the ceiling panel 100 is fixed to the column 12 of the building unit 1 using a nail and a joining member such as a joining hardware 110 shown in FIG. Furthermore, as shown in FIG. 32, after the ceiling panel 100 is fixed, all the hanging tools 2206 are removed. Thereby, installation of the ceiling panel 100 to the building unit 1 is completed. FIG. 32 is a perspective view showing a state where the installation of the jig 2200 and the ceiling panel 100 of FIG. 29 to the building unit 1 is completed. In FIG. 32, the construction of the wall of the building unit 1 is almost completed.
After the installation of the ceiling panel 100 to the building unit 1 is completed, construction of the wall, interior, equipment, etc. of the building unit 1 is performed. Thereby, the manufacture of the building unit 1 other than the construction site is completed, that is, the manufacture of the building unit 1 is partially completed. Then, after the building unit 1 is transported to the construction site and installed, the jig 2200 is removed (step S212). Thereby, manufacture of building unit 1 is completed completely. In addition, you may replace suitably the order of operation | movement in the above-mentioned process S201-S212 and each process.

In addition, the use of the jig 2200 of the building unit 1 after completion of manufacture outside the construction site will be described with reference to FIG. 33 and other drawings. FIG. 33 is a diagram illustrating an example of a process from the completion of manufacturing at a place other than the construction site of the building unit 1 according to the second embodiment to the installation at the construction site.
When the manufacture of the building unit 1 at a place other than the construction site in a factory or the like is completed (step S301), the jig 2200 is lifted together with the building unit 1 via the hanging bracket 204 by a lifting device such as a crane, and the structure shown in FIG. As shown, it is loaded onto a transport vehicle 400 such as a truck (step S302). At this time, the jig 2200 lifts the plurality of pillars 12 or 22 of the building unit 1 via the plurality of engaging members 2207, thereby lifting the building unit 1. That is, the jig 2200 is used as a hanging tool for the building unit 1. FIG. 34 is a perspective view showing a state where the building unit 1 according to the second embodiment is transported.

  The transport vehicle 400 transports the building unit 1 on which the jig 2200 is mounted from the factory or the like to the construction site (step S302). After arriving at the construction site, the building unit 1 is lowered from the transport vehicle 400 by a lifting device such as a crane. Also in this case, the jig 2200 is used as a lifting tool and is lifted directly together with the building unit 1. Furthermore, the building unit 1 is installed at a predetermined position in the building by the lifting device (step S303). For example, as shown in FIG. 35, the building unit 1 may be installed on the building unit 1 that has already been installed.

Next, as shown in FIG. 36, after the installation of the building unit 1 is completed, the jig 2200 is removed from the building unit 1 (step S304). At this time, the joining of all the engaging members 2207 of the jig 2200 and the pillars 12 or 22 of the building unit 1 is released. Only the jig 2200 is lifted and removed by the lifting device. FIG. 36 is a perspective view showing a state where the jig 2200 is removed after the building unit 1 is installed.

Since the jig 2200 has high rigidity, all the pillars 12 or 22 of the building unit 1 that are lifted via the jig 2200 receive a force in the vertical upward direction from the engaging member 2207. On the other hand, when the pillar 12 or 22 of the building unit 1 is directly lifted by a plurality of slings such as a wire or a chain, the sling to which the tension acts exerts a lateral inward force that narrows the interval between the pillars 12 or 22. Or 22 For this reason, problems such as inclination, deformation, and breakage of the pillars 12 or 22 may occur. Using the jig 2200 as a hanging tool for the building unit 1 suppresses the occurrence of the above problem.
