2. Description of the Related Art Japanese Utility Model Publication No. 8-6968 describes a structure of a bent portion (corner portion) of a conventional assembled roof. At the corner of this assembled roof, a plurality of rafter members composed of rafters and a roofing material retainer are radially arranged outward and a pair of corner girders supporting the rafter members are respectively provided. It is arranged so as to be bent in a stepwise manner. The inner corner girder is configured by connecting a plurality of trapezoidal partial girders in plan view, and the end of the rafter member is attached to the center of each partial girder. Further, the outer corner girder is formed by alternately connecting a plurality of partial girders having a trapezoidal shape in a plan view and a plurality of connecting girders arranged between the partial girders. Is attached.

[0003]

In such an assembled roof, the size of the radius (bending radius) outside the corner can be adjusted by the length of the connecting girder, but the size of the radius inside the corner is small. It was necessary to adjust the length of the partial girder, and the inner partial girder had to be a dedicated part that varied depending on the radius of the corner. On the outside of the corner, if the connecting girder is provided with a roofing material (panel) retainer, it is possible to cope with "tilting". On the inside of the corner, if the partial girder is long (the radius is large), the partial girder itself is In this respect, it was necessary to provide a material retainer, and in this regard, the inner partial girder had to be a dedicated part.

[0004] It is an object of the present invention to provide an assembling roof in which a receiving girder for receiving rafter members can be made general-purpose, and can be adapted to different bending radii.

[0005]

The bending angle of the bending portion can be adjusted by the number of the inner receiving girders, and the bending radius inside the bending portion can be adjusted by the length of the inner connecting girder. Similarly, since the outer girder member outside the curved portion that supports the rafter member is composed of the outer receiving girder receiving the rafter member and the outer connecting girder disposed between the outer receiving girder, the bending angle of the curved portion is reduced. The number of the outer receiving girders can be adjusted, and the radius of curvature outside the bending portion can be adjusted by the length of the outer connecting girder. Therefore, the inner connecting girder and the outer connecting girder are dedicated members under the influence of the radius of the curved portion, but the inner receiving girder and the outer receiving girder can be general-purpose members. Also,
Although the number of the inner and outer receiving girders is gradual, the number thereof can be adapted to the bending angle of the bending portion with their numbers. In addition, it is preferable to form a holding member for holding the roofing material on the inner connecting girder and the outer connecting girder which are exclusive members.

In this case, the inner receiving girder and the corresponding outer receiving girder are arranged parallel to each other, and the inner connecting girder and the corresponding outer connecting girder are arranged parallel to each other. Is preferred.

According to this structure, if the holding members for holding the roofing material are formed on the inner connecting girder and the outer connecting girder which are the exclusive members, the both ends of the roofing material locked by the holding member are formed. They can be formed in parallel, and processing of the roofing material in the curved portion can be facilitated.

According to this structure, the pair of curved girder members for supporting the rafter members are each constituted by the receiving girder receiving the rafter members and the connecting girder disposed between the receiving girder members. The angle can be adjusted by the number of girders,
In addition, the bending radius of the bending portion can be adjusted by the connecting girder. Therefore, the connecting girder becomes a dedicated member under the influence of the radius of the curved portion, but the receiving girder can be a general-purpose member. Although the number of the receiving girders is stepwise, the number of the girders can be freely adjusted to the bending angle of the bending portion with the number thereof.

The inner straight girder 14 and the outer straight girder 19 are the same as long ones, and the end face on the curved portion 1a side is formed (cut) at a right angle. In the first inner receiving girder 11 connected to the inner straight girder 14, the end face on the inner straight girder 14 side is formed at a right angle, and the end face on the inner connecting girder 13 side is inclined.

The inner connecting girder 13 is relatively short, and its both end surfaces are formed obliquely, and the angle formed thereby is 15 °. The outer connecting girder 18 is relatively long, and in this case also, both end faces are formed obliquely, and the angle formed thereby is 15 °. In this manner, the end faces of the first inner receiving girder 11, the second inner receiving girder 12 and the inner connecting girder 13 constituting the inner girder member are formed obliquely, and the first outer receiving girder constituting the outer girder member. By forming the end faces of the second outer receiving girder 17, the second outer girder 17 and the outer connecting girder 18 at an angle, the curved portion 1a is formed into a polygon and curved at 90 °. In addition, a total of four rafter members 5 arranged in the curved portion 1a extend radially from the inside to the outside at an angle of 30 ° to each other.

Here, with reference to FIG. 4, the cross-sectional structure of the rafter member 5 and the cross-sectional structure of each girder material in the curved portion 1a of which the inner connecting girder 13 is an example will be briefly described. The rafter member 5 is composed of a rafter 31 and a panel retainer 32, which are integrally arched in the longitudinal direction. A pair of left and right swallowing grooves 33 is formed between the upper surface of the rafter 31 and the lower surface of the panel retainer 32.
The side edges of the panel 7 are inserted into the left and right sides, and are fixed watertight.

The inner connecting girder 13 includes a hollow girder main body 41,
A gutter portion 42 that extends sideways from the lower end of the girder body 41
And a panel pressing member 43. A second inner reinforcing member (first inner reinforcing member 21) 22 is fixed in the hollow interior of the girder main body 41. The upper part of the girder main body 41 is formed in a roof shape in conformity with the arched roof main body 3, and a pair of mounting pieces 44, 44 for mounting the rafter members (rafters 31) 5 are diagonally extended on the inner slope. A panel pressing member 43 is screwed to the outer slope. The front and rear edges of the panel 7 are fixed to a panel swallowing groove 45 formed between the panel holding member 43 and the beam main body 41.

On the lower surface of the girder main body 41, a dovetail groove 46 having a C-shaped cross section is formed, and the inner connecting girder 13 is fixed to the upper end of the column 2 at the part of the dovetail groove 46. I have. In addition, the inner connecting girder 13 and the outer connecting girder 18 have
The panel holding member 43 is attached, but the first inner receiving girder 11, the second inner receiving girder 12, the first outer receiving girder 16 are provided.
Also, in the second outer receiving girder 17, the panel pressing member 43 is omitted so that rainwater can flow down smoothly (see FIG. 3).

As described above, according to the present embodiment, the inner girder 4a in the curved portion 1a is connected to the first and second inner receiving girder 11, 12 for supporting the rafter member 5 and the inner girder connecting them. Since it is composed of the connecting girder 13, the bending angle of the bending portion 1 a can be adjusted by the number of the second inner receiving girder 12, and the bending radius inside the bending portion 1 a can be adjusted to the length of the inner connection girder 13. You can adjust it. Similarly, since the outer girder 4b in the curved portion 1a is composed of the first and second outer receiving girder 16, 17 for supporting the rafter member 5, and the outer connecting girder 18 for connecting them. The bending angle of the bending portion 1 a can be adjusted by the number of the second outer receiving girders 17, and the bending radius outside the bending portion 1 a can be adjusted by the length of the outer connecting girder 18.

The bending angle of the bending portion 1a in this embodiment is, for example, 30 °, 60 °, 90 °, or the like.
Can be selected in 30 ° increments. Needless to say, if the angle of the end face of each girder is made smaller, the selection range is expanded. As described above, since the bending angle of the curved portion 1a is determined by the number of the second inner receiving girder 12 and the second outer receiving girder 17, these can be used as general-purpose members for angle adjustment.

Since the end faces of the inner connecting girder 13 and the outer connecting girder 18 are also formed obliquely, it is not necessary to make the angles of the receiving girders 11, 12, 16, 17 extremely large. Can be connected without difficulty. Further, since the panel holding member 43 is attached only to the inner connecting girder 13 and the outer connecting girder 18 arranged in parallel with each other, the trapezoidal panel 7 can be easily mounted.

Next, referring to FIG. 5, FIG. 6 and FIG.
A second embodiment of the present invention will be described. As shown in FIG. 5, the prefabricated building 1 of this embodiment is installed in a portion where a flat portion goes uphill. In this assembled building 1, a roof body 3 as an assembled roof is placed and fixed on the upper ends of four sets of columns 2, and the roof body 3 is an intermediate curved portion 1b.

A first lower reinforcing member 61 having a bent portion at one place and a first side reinforcing member 62 are attached between the linear girder 54 and the connecting girder 53 in the hollow portion thereof,
A second lower reinforcing member 63 having two bent portions and a second side reinforcing member 64 are mounted in the hollow space between the two connecting girders 53 with the receiving girder 52 therebetween. Further, upper reinforcing members 65 are attached between the first receiving girder 51 and the connecting girder 53 and between the second receiving girder 52 and the connecting girder 53, respectively.

Both ends of the 2 and the connecting girder 53 are formed at an oblique angle of 5 °. As described above, the first receiving girder 51, the second receiving girder 52, and the connecting girder 5 constituting the curved girder member of the bending portion 1 b are provided.
3 is formed obliquely, so that the curved portion 1b forms a polygon and is curved at 20 °. Further, a total of three rafter members 5 arranged in the curved portion 1b extend radially from the upper side to the lower side at an angle of 10 ° to each other.

Here, with reference to FIG. 7, the cross-sectional structure of the rafter member 5 and the cross-sectional structure of each girder member in the curved portion 1b of the connecting girder 54 will be briefly described. As in the first embodiment, the rafter member 5 includes a rafter 31 and a panel retainer 32.
The side edge of the panel 7 is obliquely inserted into the swallowing groove 33 in accordance with the angle of the curved portion 1b.

Similarly to the first embodiment, the connecting girder 53 has a hollow girder main body 41, a gutter portion 42, and a panel pressing member 43. Further, the second lower reinforcing member (first lower reinforcing member 61) 63 is fixed to the inside of the hollow of the girder main body 41 at the bottom surface thereof, and the second lower reinforcing member 61 is positioned at the inner surface thereof.
A side reinforcing member (first side reinforcing member 62) 64 is fixed, and an upper reinforcing member 65 is fixed on the top surface. The panel girder 53 is attached to the connecting girder 53. However, the first girder 51 and the second girder 52 omit the panel girder 43 so that rainwater can flow down smoothly. (See FIG. 6).

As described above, according to the second embodiment,
Since the beam in the curved portion 1b is composed of the first and second receiving beams 51 and 52 supporting the rafter member 5 and the connecting beam 53 connecting these beams, the bending angle of the curved portion 1b is
The number of the second receiving beams 52 can be adjusted, and the bending radius of the bending portion 1b can be adjusted by the length of the connecting beam 53. The bending angle of the bending portion 1b in this embodiment is 10 degrees, 20 degrees, 30 degrees, and 4 degrees.
It can be selected in increments of 10 °, such as 0 °. Needless to say, if the angle of the end face of each of the columns 51, 52, 53 is made smaller, the selection range is expanded. As described above, since the bending angle of the bending portion 1b is determined by the number of the second receiving girders 52, this can be used as a general-purpose member for angle adjustment.

In the second embodiment, the prefabricated building that curves upward from the flat part has been described. However, it is needless to say that the present invention can be applied to the prefabricated building that curves downward from the flat part.

As described above, according to the assembled roof of the present invention, the girder of the curved portion is formed by alternately connecting the receiving girder receiving the rafter member and the connecting girder connecting these members. Therefore, the receiving girder receiving the rafter member can be made a general-purpose one, and can be made to freely correspond to different bending radii of the curved portion.
