DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a roof mounting method in a unit type construction and a unit type roof unit structure for construction according to the present invention will be explained based on examples shown in the drawings.

First, in the main body unit 1 to which the roof is attached, three main body unit structures 2a, 2b and 2c are arranged perpendicularly to the flow direction R of the roof and are integrally connected to form one unit. Each main body unit structure 2a,
2b and 2c are a pillar 21, an upper beam 22, and a lower beam (not shown).
It is formed in a rectangular parallelepiped shape that is integrally connected. The diaphragm 210 is welded to the top of the column 21, and the nut plate 211 and the nut 212 are welded to the back surface of the diaphragm 210 to form the main body side joint portion 3.

As shown in FIG. 5, the roof unit structure 4 comprises a beam member 5, an oblique beam member 6 and a joint portion. The beam member 5 and the oblique beam member 6 are formed in a size corresponding to the upper beam 22 of the main body unit structure to which they are joined. The oblique beam member 6 is provided with a joint portion 7 at the intersection with the beam member 5 toward the outside. The joint portion 7 is formed in a box shape with an open top, and an insertion hole 72 is provided in a bottom plate 71 at a position corresponding to the nut 212 of the main body side joint portion 3. A plurality of such roof unit structural bodies 4 are arranged in the same direction as the arrangement direction of the main body unit structural body, that is, perpendicular to the flow direction R of the roof, and are joined to the main body unit structural body by bolts to be described later. The roof unit components 4 are integrally joined to each other to form one roof unit 8.

Here, the mounting of the roof unit structure 4 and the bolts will be described in detail.

First, the bolts 10 to 14 are inserted into the main body side joint portions 3 of the built-up main body unit 1 on site, and the bolts are fastened to the nuts 15. At this time, the joint plate 16 is bridged between the pillars 21 of the adjacent main body unit constituents 2a and 2b and between the pillars 21 of the main body unit constituents 2b and 2c. 11, 12, 13 are fastened. As a result, the joining bolts 10, 13 and 14 are erected and fixed on the main body unit 1 side.

Each bolt 9, 10, 13, 14 is shown in FIG.
As shown in (a) and (b), when the roof unit structure 4 is attached, each height is adjusted in advance so that the slant beams 6 are inclined at a predetermined angle along the roof slope. There is. That is, the nut 15 of the joining bolt 10 simultaneously functions for height adjustment, and the joining bolt 13 and the joining bolt 14 are preliminarily screwed with the nut 17 for height adjustment. Since the joint bolt 9 is a joint on the underwater side of the roof and has a gradient of zero, the height is not adjusted. The roof unit structure 4 is not inserted into the bolts 11 and 12. In this way, the slope of the roof unit structure 4 and thus the roof unit 8 is uniquely determined by the joining bolts 9, 10, 13, 14.

Next, the bolt insertion hole 72 of the joint portion 7 of the roof unit construction bodies 4a and 4c on the water side and the water side of the roof.
The above-mentioned joining bolt 10, joining bolt 13 and joining bolt 14 are inserted into the roof unit structure 4a, 4c.
Is fastened to the bottom plate 71 with the nut 18. At this time, the joining bolt 9 is inserted into the underwater joint portion 7 of the roof,
It is fastened to the bottom plate 71 with the nut 18.

Next, a connecting beam 19 is connected between the roof unit components 4a and 4c. That is, the connecting beam 19 is attached to the side plate 73 of the right-side joint portion 7 of the roof unit constituent body 4a of FIG. 1A and the side plate 73 of the left-side joint portion 7 of the roof unit constituent body 4c of FIG. It is tightly bound.

After the roof structure is formed in this manner, a roof material (not shown) made of an appropriate material is fitted into the corrugated tight frame 50 provided on the beam 5 of the roof unit structure 4 to secure the bolt. It is fixed by. In this way, the roof unit 8 is attached to the main body unit 1. The shape of the roof according to this embodiment is a one-way roof as shown in FIGS.

Next, the operation of the above embodiment will be described.

First, the roof unit structure 4 and the joining bolts 9, 10, 13, and 14 are standard-produced in the factory, while the main body unit structure is standard-produced in the factory. Speaking of work performed in the field, it is necessary to insert bolts 10, 13, 14 for joining into the joint portion 3 of the main body unit structure and fasten these bolts 10, 13, 14
By simply inserting the roof unit structure 4 into the housing and inserting the joining bolts 9 and tightening them, and connecting the connecting beam 19 between the roof unit structures 4a and 4c, a very simple operation is performed. Yes, this allows the roof structure to be completed easily and quickly.

In addition, the roof unit structure 4 has a beam member 5 and a slant beam member 6 formed in a size corresponding to the upper beam 22 of the main body unit structure, and in the same direction as the arrangement direction of the main body unit structure. Are lined up and joined. Therefore, as shown in FIG. 7, the main body unit structure bodies 2a, 2b, 2c are temporarily assumed.
Even if the clearance between them is not constant and an error in the horizontal direction such as x ≠ y occurs, the hole 213 of the nut 212 of the main body-side joint 3 and the joint 7 of the roof unit structure 4 are joined together.
The bolt insertion hole 72 does not become inconsistent. Therefore, highly accurate construction can be efficiently performed. Further, since the bolt insertion hole does not need to be re-drilled on site, not only the workability is good, but also the stress is not reduced.

As a result, the work period can be greatly shortened.

Since the roof unit structure 4 itself has a substantially two-dimensional shape as shown in FIG. 5, its bulkiness is as small as possible. Further, the width of the main body unit structure is set so that it can be placed flat on a truck for transportation. Since the roof unit constituent body 4 is formed in a size corresponding to the main body unit constituent body, its width is inevitably set to such a width that it can be placed flat on the truck. Therefore, there is almost no difficulty in transportation in combination with the lack of bulk.

The roof mounting method and the unit type roof unit structure for unit type building according to the present invention are not limited to the above-mentioned embodiment.

First, the shape of the roof is arbitrary. For example,
It can also be applied to a double-flow roof as shown in FIG. In this case, the roof unit structure 4 is arranged on both sides of the roof below the water, and the roof unit structure 4a, 4a
In the meantime, a connecting beam 19 which is bent to bend is connected. In this case, the base length of the connecting beam 19 may be about the same as the base length a of the roof unit structure 4a, but may be about ½ as shown in the figure.

The number of roof unit constituents 4 is arbitrary. FIG. 11 shows an example in which the main body unit structure is divided into two, which is smaller than that in the above-described embodiment, and FIGS. In the case of FIG. 11, the connecting beam 1
9 is not used, and in the case of FIGS. 12 and 13, since the number of roof unit constituent bodies 4 is smaller than the number of main body unit constituent bodies, the connecting beam 19 includes two main body unit constituent bodies 2.
It is formed to have a length that extends over b or is used by connecting two pieces. In addition, in the case of FIG. 12, the connecting beam 1 connected between the roof unit constituent bodies 4a and 4a on the underwater side of the roof.
9 is bent almost.

Further, in the above embodiment, the case where the number of the main body unit 1 is one is illustrated, and the case where the number of the roof units 8 is one is mentioned. However, the number of roof units 8 is arbitrary as long as it corresponds to the number of main body units 1. Therefore, as shown by the alternate long and short dash line in FIG.
It can also be applied to a case in which a plurality of are installed in the horizontal direction. In this case, as shown in FIGS. 3 and 4, between the adjacent roof unit constituents 4a and 4a and the roof unit constituent 4
The joint portions 7 and 7 between c and 4c are integrally joined by the bolts and nuts 23.

Furthermore, the roof mounting method and the unit type roof unit structure for a unit type building according to the present invention can be used by appropriately combining the above respective examples.
