Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure which mainly constitutes a roof among building units which constitute a unit building.

[0002]

2. Description of the Related Art Conventionally, as a roof structure, there is known a roof structure in which a decorative roof portion is arranged on an inclined surface. For example, in Japanese Utility Model Laid-Open No. 62-273348 or Japanese Utility Model Laid-Open No. 62-273349, a plurality of trusses are assembled on the upper surface of the roof panel already constructed on the building body,
There is disclosed a structure in which a decorative roof portion is formed by arranging a tree or a roof material on the truss.

Further, Japanese Utility Model Laid-Open No. 63-163310 discloses a dome mount which is erected at the edge of the roof opening, and the dome body is externally fitted and fixed to the dome mount.

[0004]

However, in the conventional roof structure as described above, a complicated truss or the like is placed on the roof panel already installed on the building body, or the dormer body is placed on the roof panel. Since the number of work steps is large and the workability is poor, and the skill is required for the construction, there is a possibility that the finish may vary and the appearance quality and waterproofness may be impaired.

Therefore, the present invention provides a roof structure which reduces the number of steps for work at a high place on site, can obtain a uniform finish without requiring skill in construction, and has good work efficiency. That is the issue.

[0006]

In order to solve the above problems, the present invention provides a roof structure in which a decorative roof portion is provided so as to project from a part of the roof body, wherein the roof body has a plurality of roof units. It is characterized in that it is arranged adjacent to each other, and that the optional roof unit has a roof structure in which the decorative roof portion is integrally formed.

The optional roof unit has a main body side portion that constitutes a part of the roof main body and a decorative roof portion that is provided so as to project to the eaves side of the main body side portion, and the main body side portion and the decorative roof portion The roof portion is a combination of a lower chord member extending over the main body side portion and the decorative roof portion in a rectangular shape, and is attached on the lower chord member,
It is also possible to form a skeleton by arranging beams, rafters, etc., and arranging a roofing material on the skeleton to integrally form the roof material.

[0008]

In the roof structure having such a structure, since the decorative roof portion is integrally formed on the roof unit in advance, it is only necessary to place a plurality of roof units on the upper part of the building unit and separately decorate it on site as in the conventional case. There is no need to form a roof.

Therefore, the quality of the appearance and the waterproofness will not be deteriorated due to variations in the finish.

Further, since work steps at high places can be reduced as compared with the conventional method, workability is excellent.

[0011]

1 to 8 show an embodiment of the present invention.

The roof structure of this embodiment has a plurality of roof units 2 having the same shape, and a roof unit 3 having mutually symmetrical shapes.
1, 32 are mounted on the upper part of the building unit 1 ... And are combined with each other.

In both roof units 31, 32, main roof side portions 41, 42 are integrally formed with decorative roof portions 51, 52.

Since both roof units 31 and 32 have symmetrical shapes, a more specific configuration will be described by taking one roof unit 31 shown in FIG. 2 as an example.

That is, in this roof unit 31, the long chords 8, 8 and the short chords 9, 9 as lower chord members that straddle the main body side portion 41 and the decorative roof portion 51 are combined in a rectangular shape, and Or 8, 9 to 10 on the side of the main body 41, and 1 on the side of the decorative roof 51.
A plurality of 3 are erected substantially vertically. Further, a shed beam 11 is arranged between the shed 10 and the long haze 8. A plurality of rafters 12 having different lengths for supporting a roof material (not shown) are arranged on the main beam 11 ... On the main body side 41 side along the roof flow direction. Further, on the side of the decorative roof portion 51, the upper chord members 15 are arranged on the huts 13 ... Between the upper chord members 15 and the long mist 8,
A plurality of rafters 17 having different lengths are arranged along the roof flow direction on the decorative roof portion 51 side. By laying a roof material (not shown) on the upper side of the rafters 17 ..., The decorative roof portion 51 side is formed with substantially the same slope as the main body side portion 41 side.

Further, fixing metal fittings 18 are fixed to the four corners of a quadrangle formed by the long mist 8,8 and the short mist 9,9.

Reference numeral 14 is a truss material for reinforcement.

On the other hand, as shown in FIG. 3 etc., the roof unit 2 is formed in a triangular prism shape as a whole by a mist 60 ..., a shed 61, and a rafter 62. A fixing bracket 69 is arranged around the roof unit 2.

Next, such roof units 2, ..., 31, 4
The assembly of No. 1 will be described.

The roof units 2, ..., 31, 41 are
On the plurality of building units 1 ..., mainly as shown in FIG.
It is placed with a constant interval H. This constant interval H
Is set to a width that the operator can enter. The mounting state will be described by taking the A, B and C portions of FIG. 1 as an example. First, the A part is shown in FIG. 6, and the upper ends of the pair of roof units 2 and 2 are connected by the plate 67, and the lower ends of the pair of roof units 2 and 2 are bolted via fixing fittings 69 protruding from the units 2 and 2. 6
5 · Attached with nut 66. In addition, reference numeral 68 in FIG. 6 indicates a roof material.

Further, as shown in FIG. 7, the portion B is screwed by a tubular member 71 with a waterproof steel plate 70 interposed between the roof unit 2 and the building unit 1.

Further, as shown in FIG. 8, the C portion is screwed through the tubular member 71 with the waterproof steel plate 70 interposed between the roof unit 2 and the building unit 1 as in the B portion. Has been done.

The roof unit 2 placed in this way
…, 31 and 32 are roof unit 2 ... and roof unit 3
A roof main body 80 is formed by the main body side portions 41, 42 of 1, 32, and decorative roof portions 51, 52 project from the roof main body 80.

In the thus constructed roof structure, the roof units 31 and 32 are integrally formed with the decorative roof portions 51 and 52 in advance, so that the roof units 31 and 32 are mounted on top of the building units 1 and 1. It is only necessary to place it, and there is no need to construct it separately from the roof body 80 on site like in the past,
It is possible to reduce the number of man-hours on site, improve workability, and suppress quality variations.

Further, since work steps at high places can be reduced as compared with the conventional method, workability is good.

Further, the roof units 2, ..., 31, 3
When the 2 is placed on the building units 1 and 1, they are placed at a fixed interval H, so this interval H can be used as a construction space, and the flat on the building units 1 and 1 can be used. It is possible to secure a solid footing. Therefore, the safety is further improved, and the work efficiency at the time of assembly is also good.

[0027]

As described above, according to the present invention, since the decorative roof portion is integrally formed with the roof unit in advance, the decorative roof can be simply mounted on the building unit. Since it is possible to provide a roof structure having a portion, it is not necessary to separately form a decorative roof portion as in the conventional case. Therefore, there is no variation in the finish, and the appearance quality and waterproofness are not impaired. Further, since the work process at a high place can be reduced as compared with the conventional method, the workability is excellent, which is a practically useful effect.
