DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 3 shows the frame assembly 12 of the roof unit 10. As shown in this figure, the frame assembly 12 of the roof unit 10
The girder truss 14, the girder truss 16, the girder eaves frame 18, the girder eaves frame 20, and a pair of corner ridge frames 22 are assembled to each other.

More specifically, the girder truss 14 is structurally configured as a truss structure by hingedly connecting a string member such as an upper chord member and a lower chord member and a web member such as a vertical member and a diagonal member. , And the longitudinal direction is arranged in the girder direction. One end of the girder truss 14 in the longitudinal direction is provided with a wife truss 16 having a triangular shape in a side view.
Are mounted orthogonally. Further, the other end of the girder truss 14 in the longitudinal direction is assembled so that one end of the eaves end frame 20 configured as a frame material instead of the truss is parallel to the end truss 16. At the other end of the wife truss 16 (i.e., the end on the eaves end side) and at the tip end of the eaves eaves frame 20 (same left), the girder eaves frame 1 disposed parallel to the girder truss 14 is provided.
8 are assembled at both ends in the longitudinal direction. Further, at the protruding corner position, more specifically, at the joint between the girder eaves frame 18 and the eaves eaves frame 20 and the position connecting the top of the girder truss 14, each has a substantially U-shaped cross section (channel steel) and has a predetermined shape. A pair of corner ridge frames 22 arranged close to each other with a gap 24 (see FIG. 1) are assembled. This allows
A frame assembly 12 is configured.

Note that rafters 26 are provided at predetermined intervals on the roof surface component of the frame assembly 12.
On these rafters 26, a girder-side base plate 28 formed in a trapezoidal plate shape and a wife-side base plate 30 formed in a triangular plate shape are attached (see FIG. 4). In a state where the girder side base plate 28 and the wife side base plate 30 are assembled,
A predetermined gap 32 is formed between the two. The gap 32 is vertically opposed to the gap 24 between the pair of corner ridge frames 22 described above, and communicates with each other.

The predetermined positions in the frame assembly 12 described above (the top surface of the girder truss 14 on the side of the truss 16, the end surface of the girder truss 16 on the side of the truss 16, and the frame 2 of the girder truss 14.
A rectangular plate 42 in which a bolt insertion hole 38 is formed at the upper end of a channel steel 36 and a weld nut 40 is welded to the back surface is welded to a conventional hanging bracket 34 (the upper surface at the end on the 0 side). Fixed structure) is fixed by welding. The hanging bracket 34 is attached when the roof unit 10 is assembled in a factory.

Further, at a predetermined position of the pair of corner ridge frames 22 in the frame assembly 12, a hanging metal fitting 44 of a type different from the conventional hanging metal fitting 34 is provided. The hanging bracket 44 is also attached when the roof unit 10 is assembled in a factory.

More specifically, as shown in FIGS. 1 and 2, the hanging fitting 44 is formed in a rectangular plate shape, and is inserted into the gap 24 between the pair of corner ridge frames 22 described above.

A bolt insertion hole (not shown) is formed at one end 44A of the suspension fitting 44. Correspondingly, a coaxial bolt insertion hole (not shown) is also formed in the webs 22A of the pair of corner frames 22. ) Is formed. A weld nut 45 is welded in advance to a portion of one corner ridge frame 22 where the bolt insertion hole is formed. Then, the stepped bolt 46 is screwed into the weld nut 45 with the bolt insertion hole formed in one corner ridge frame 22 and the bolt insertion hole of the one end 44A of the suspension fitting 44 positioned coaxially. ing. Thus, the suspension fitting 44 is rotatably supported around an axially intermediate portion of the stepped bolt 46 (this portion has a smooth peripheral surface). Further, a wire locking hole 48 for locking the end of the wire when lifting with a crane (not shown) is formed in the other end 44B of the hanging bracket 44.

In the above configuration, the weld nut 45 is welded to one corner ridge frame 22 in advance.
Instead of this, a configuration may be adopted in which a normal nut is screwed in after the stepped bolt 46 is inserted.

Next, the operation and effect of this embodiment will be described. When the roof unit 10 is loaded on the carrier of the transport vehicle after being produced in the factory, or when the transport unit transports the roof unit 10 to the site and then lowers it from the carrier of the transport vehicle to a temporary storage location, It is necessary to lift the roof unit 10 using a crane when the roof unit 10 is actually installed on the top of a predetermined living room unit at the site. In this case, according to the present embodiment, the roof unit 10 can be lifted as follows.

First, as shown in FIG. 2, one end 44A is inserted into a gap 24 between a pair of
6, the other end 44 </ b> B of the hanging metal fitting 44 suspended by its own weight is grasped and rotated upward with respect to the corner ridge frame 22 around the stepped bolt 46. As a result, as shown in FIG.
4B appears above the pair of corner ridge frames 22. At the same time, above the gap 24 between the pair of corner ridge frames 22, a predetermined gap 32 set between the girder side base plate 28 and the wife side base plate 30 is vertically opposed and communicates with each other. As a result, the other end portion 44B of the hanging metal fitting 44 projects upward through the gap 32 between the girder-side base plate 28 and the wife-side base plate 30 above these base plate surfaces. In this state, the wire locking hole 4 formed in the other end portion 44B of the hanging bracket 44
8 is positioned above the baseboard surface (see FIG. 4). This state is the use state of the hanging fitting 44.

In addition, at a predetermined position other than the hanging metal fittings 44 arranged at the above-mentioned protruding corner positions, the conventional hanging metal fittings 34 are provided.
The work of screwing an eyebolt (not shown) into the weld nut 40 on the back surface of the plate 42 is required for these hanging fittings 34, but this work may be performed in a factory in advance. .

Next, the ends of the wires of the crane are locked to the wire locking holes 48 of the hanging fittings 44 and the eyebolts of the hanging fittings 34. After that, the roof unit 10
May be lifted and moved to a predetermined position. In addition,
At this time, in the case of the hanging bracket 44, one end portion 44A
Are rotatably supported by the stepped bolts 46, so that the hanging fittings 44 are rotated in the direction of the tension acting by the wire (see the two-dot chain line in FIG. 1).

After the roof unit 10 is installed at a predetermined position, the hanging bracket 44 is no longer necessary. Therefore, by rotating the hanging bracket 44 around the stepped bolt 46,
As shown in FIG. 2, it is stored in a gap 24 between a pair of corner ridge frames 22. In addition, when the hanging bracket 44 becomes unnecessary, the stepped bolt 46 is connected to the weld nut 45.
And the hanging fitting 44 itself may be detached from the corner ridge frame 22.

As described above, in the present embodiment, the suspension fitting 44
Is formed in a flat plate shape, and is inserted into the gap 24 between the pair of corner ridge frames 22. Further, one end 44A of the hanging metal fitting 44 is rotatably supported using a stepped bolt 46, and the hanging metal fitting 44 is turned into a corner. Since the wire locking hole 48 positioned above the base plate surface when the wing frame 22 is rotated upward with respect to the ridge frame 22 is formed in the other end portion 44B, the hanging metal fitting 4 is provided.
The wire itself or the wire locked in the wire locking hole 48 of the hanging bracket 44 does not interfere with the girder side base plate 28 and the wife side base plate 30. Therefore, these girder side ground plates 2
8. It is possible to mount the wife side base plate 30 on the frame assembly 12 via the rafter 26 in advance in the factory. Therefore, it is possible to abolish the work of attaching the base plate 30 especially at the site. As a result, work efficiency at the site can be improved.

Further, as described above, when the conventional type of hanging bracket 34 is used, it is necessary to attach an eye bolt at the time of use, and it is necessary to remove the eye bolt after use. According to
The stepped bolt 4
Since it is only necessary to rotate the hanging fittings 44 around six times, work can be saved in this respect as well, and work efficiency on site can be improved.

Further, in the case of the conventional suspension fitting 34, a channel steel 36 (or a square steel pipe), a plate 42,
In addition, the weld nut 40 needs to be pre-assembled by welding. For this reason, the number of components is increased, and the number of manufacturing steps is disadvantageously increased. However, since the hanging bracket 44 of the present embodiment is a single component configured in a plate shape, the number of components can be reduced. In addition, the number of manufacturing steps can be reduced.

In addition, welding was required to attach a conventional type of hanging metal fitting 34 to a predetermined position of the frame assembly 12, but in the case of using the hanging metal fitting 44 of the present embodiment, a stepping step was carried out on the weld nut 45. Since it is only necessary to perform the fastening operation of screwing the bolt 46, the labor of the operation can be saved. When a normal nut is used instead of the weld nut 45, all of the welding work can be omitted for the suspension fitting 44.

In the case of the hanging metal fittings 44 according to the present embodiment, when they become unnecessary, the hanging metal fittings 44 can be rotated around the stepped bolts 46 for storage or detachment of the hanging metal fittings 44 themselves. Therefore, there is no problem that the hanging metal fitting 44 interferes with the tile at the time of the subsequent tile construction.

Further, since the hanging bracket 44 of the present embodiment has one end 44A rotatably supported by the stepped bolt 46, as described above, when the roof unit 10 is lifted, the hanging bracket 44 is moved. Rotate in the direction of wire tension. For this reason, it is possible to prevent excessive stress concentration from occurring around the wire locking hole 48 of the suspension fitting 44.

In the present embodiment, the stepped bolt 46 is used as the rotation center axis of the hanging member 44. However, the present invention is not limited to this, and a rivet may be used, and one end 44A of the hanging member 44 can be rotated. Any member (support shaft) that functions as a supporting rotation center shaft can be applied.

In this embodiment, one end 44A of the suspension fitting 44 is rotatably supported by the stepped bolt 46, in other words, a step is formed with respect to the inner diameter of the bolt insertion hole formed in the one end 44A. The outer diameter of the intermediate portion in the axial direction of the bolt 46 is set to be slightly smaller. However, the present invention is not limited to this. Alternatively, a configuration may be adopted in which the member serving as the rotation center axis is inserted tightly. For example, when assembling in a factory, the hanging metal fittings 4 may be in the state shown in FIG.
After the member 4 is inserted into the gap 24 between the pair of corner building frames 22, the member serving as the rotation center axis such as the stepped bolt 46 may be tightly inserted by hitting with a hammer or the like. In this case, when the hanging bracket 44 becomes unnecessary, the side surface of the other end 44B of the hanging bracket 44 is hit with a hammer or the like and stored in the gap 24. That is,
The “rotatable” described in claims 1 and 2 includes:
In addition to the “rotatable” as in the present embodiment, the case of “tightly inserting” as described above is also included as long as it is rotatable.

Further, in the present embodiment, when assembling the roof unit 10 in the factory, the structure in which the hanging metal fittings 44 are attached to the corner building frame 22 of the frame assembly 12 in advance is adopted. In this case, it is not always necessary to do so, and when it becomes necessary to actually lift the roof unit 10, the hanging bracket 44 may be retrofitted using the stepped bolt 46.

Further, in the present embodiment, the hanging metal fittings 44 formed in a plate shape are provided for the corner ridge frame 22 arranged at the protruding corner position. However, the present invention is not limited to this. A similar hanging metal fitting 44 may be provided between a pair of land ridge frames (large ridge frames) of a roof unit which is a channel steel) and is disposed adjacently with a predetermined gap. That is, the “ridge frame” in the present invention includes the corner ridge frame 22 in the present embodiment and also the land ridge frame (large ridge frame).

Further, in the present embodiment, the plate-shaped suspension fittings 44 are provided only on the corner ridge frame 22 disposed at the protruding corner position, and this is useful, but not limited thereto. Alternatively, it is possible to adopt a configuration in which a plate-shaped hanging member 44 is provided instead of the hanging member 34 at all other positions where the conventional hanging member 34 is provided.
