DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of roofs of various structures, in which a folded metal roof is fixed on a base material.

[0002]

2. Description of the Related Art In order to fix a folded plate roof on a base material so as to form a roof, first, a folded plate support is fixed on a base material such as a beam material, and the folded plate roof is fixed thereon. . There are various types of folded-plate roofs, and there are also various folded-plate supports for fixing them. Above all, after the edges of the folded plate roof are abutted with each other, the edges are locked to the fixing bracket on the top of the folded plate support,
The folded-plate roof structure that fits fitting members such as clips and caps and fixes it so that it grips between the edges of adjacent folded-plate roofs is easy to work and has a good fixed state It is useful because it is.

[0003] However, unlike the folding type roof structure of the folding type in which the hanging member is fixed on the upper part of the folding plate support, it is not easy to cope with the inclination of the roof. That is, if it is a hanger, it can be tilted around a fixing bolt inserted in the left-right direction as an axis. However, this cannot be done with a folded plate supporting bracket having a structure in which a fixing bracket is placed on a bracket main body.

For this reason, the following two methods have been adopted. The first is the stage of steelwork, where columns and beams are assembled.
The other one is to set the upper surface of the beam to a predetermined inclination angle corresponding to the slope of the roof. It is to fix at an angle.

[0005] However, in the former case, since the steelwork and the roofing work are usually performed by different contractors, the work is not often performed with a correct slope as planned. I forget to put it on,
Roofing work was greatly affected. In the latter case, fixing the folded plate support is troublesome, and a small difference in angle appears as a large difference when the folded plate roof is fixed.

Therefore, an invention (Japanese Patent Application No. Hei 7-149573) for solving all of the above problems was made (see FIG. 7).
As a result, the work of fixing the folded roof can be performed easily and quickly.

[0007] By the way, the folded plate supporting bracket 10 as described above.
1 requires a structure (receiving portion 106) for receiving the lower surface of the bulging portion 105 projecting from the folded plate roof 102 to a position between the fitting main body 103 and the fixing fitting 104. this is,
This is to prevent deformation of the folded plate roof 102 due to the load applied to the folded plate roof 102 due to snow etc. Since the receiving portion 106 is required, the metal fitting main body 103 has to be formed into a long hem shape as shown in the drawing, as is conventionally known.

[0008] For this reason, C-type steel or I-type steel is used as a base material in the roof ridge of a ridge-building, the descending ridge of a roof with a purlin, or a diagonally cut-away portion of the roof, and the width of the fixed surface is fixed. In some cases, it is impossible to fix the above-mentioned folded plate supporting bracket because of its narrow width.

[0009]

SUMMARY OF THE INVENTION Therefore, the present invention can be fixed even on a base material having a narrow fixed surface, and when a special roof structure as described above is obtained, a plurality of types of folding structures can be used. It is an object of the present invention to make it unnecessary to use a plate support and to obtain a high-strength roof structure which does not fluctuate even with snow or the like.

The means for this will be described with reference to FIG. 1 of the embodiment. The structure is such that the fixing bracket 4 is mounted on the top 9 of the bracket main body 3 so as to be tiltable in the gradient direction of the roof. The folded plate supporting bracket 2 is fixed on the base material 1, and the folded plate roof is held in a state where the edges 5 e abut against the locking pieces 17 formed on the right and left sides of the fixing bracket 4 via the rising pieces 16. 5 is a folded-plate roof structure in which the edge 5a above the bulging portion 5b is locked and fitting members 6, 7 are fitted to the edge 5a to fix the folded-plate roof 5. The lower side of the top 9 of the metal fitting body 3 is supported by two legs 10, 10 opened to a width corresponding to the width of the top 9, and these legs 10, 1
A step 14 is protruded outward from the upper part of
4 is a folded plate roof structure in which a frame-shaped receiving member 8 inserted from above is locked to receive the lower surface of the bulging portion 5b of the folded plate roof 5.

In another configuration, the fixing bracket 4 is mounted on the top 9 of the fitting main body 3 so as to be tiltable in the direction of the slope of the roof, and is provided on both left and right sides of the fixing bracket 4 via rising pieces 16. A folded plate support fitting 2 for locking an edge 5a above the bulging portion 5b of the folded plate roof 5 to the formed locking piece 17, wherein a lower part of the top part 9 of the fitting body 3 is a top part 9 Are supported by two legs 10, 10 which are opened to a width corresponding to the width dimension, and a step 14 is provided on the upper portion of the legs 10, 10 so as to project outward. And a frame-shaped supporting member 2 which locks a frame-shaped receiving member 8 which receives a lower surface of a bulging portion 5b bulging to a position corresponding to a position between the metal fitting main body 3 and the fixing metal fitting 4 in the folded plate roof 5 to be fixed. It is characterized by being.

In order to further improve the strength of the folded plate support 2, the step 14 is formed by projecting from both front and rear edges of the legs 10, 10. The distal end side may be bent to form the rib 15.

[0013]

According to the above construction, since the folded plate supporting bracket is constructed by mounting the fixing bracket so as to be tiltable with respect to the top of the bracket main body, it is influenced by the inclination of the base material. Instead of having a structure (receiving portion) for receiving the lower surface of the bulging portion of the folded plate roof, while having the effect of easily and quickly setting and fixing the folded plate roof at a predetermined slope,
Since the width of the metal fitting body can be set to be small, it is possible to fix even when the width of the fixing surface is small.

In addition, since the metal fitting body is constituted by the two legs which are opened corresponding to the width of the top portion, the load applied from above through the top portion can be sufficiently supported.
That is, since the load applied to the top portion is directly supported by the leg portion extending substantially straight downward, as compared to the shape in which the leg portion extends downward through a portion corresponding to a receiving portion projecting in the left-right direction,
Concentrated load that promotes deformation of the legs is less likely to be applied.
For this reason, it is possible to obtain a folded plate supporting bracket and a folded plate roof structure having high strength against a load.

According to the third aspect of the present invention, when the step formed on the folded plate supporting bracket is a rib, the above-described effects are obtained,
The strength can be further improved, and the shape of the main body of the folded plate supporting bracket can be simplified, the cost can be reduced, and the production can be facilitated.
