Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a roof gutter with an improved eave gutter section.

[Conventional technology]

For example, the conventional example can be found on page 120 of the ``Self-Explanatory Dictionary of Architectural Terms'' (published by Rikogakusha, 22nd edition, September 25, 1979).
The roof gutter shown on page 121 will be explained with reference to FIGS. 4 and 5.

In the system shown in FIG. 4, a "hanging neck type" gutter receiving metal fitting 11 is fixed to a building component such as a gassho 2, and multiple locations in the longitudinal direction of the gutter main body 5 made of metal or synthetic resin are attached to the gutter receiving metal fitting. 11 and fixed with copper wires (not shown). In addition, in the case shown in FIG. 5, the outer periphery of the gutter body 5, which is made of a channel-shaped iron plate with a thickness of 0.4 to 0.5 mm, is covered with eaves aggregate 13 fixed to building structural members such as columns 12. It is supported and fixed to the support member 14.

[Problem that the invention attempts to solve]

However, the conventional roof gutter as described above has a problem in that the positioning workability in the vertical and horizontal directions is not good. That is, in the roof gutter shown in FIG. 5, as shown in FIG.
At the eaves of the building, which consists of beams B and the main building 3, after assembling beams B, etc., we stretch water strings to position them in the vertical direction, and as shown in Figure 7, we perform the horizontal reference positioning. In this case, the aggregate 13 and supporting members 14
The work of assembling the roof and the work of installing the roof and gutters are performed separately by different workers due to different industries, which results in poor work efficiency and long construction times. Further, since the above-mentioned positioning work cannot be performed accurately, there is a problem that the appearance is spoiled.

The present invention solves the above-mentioned problems, and enables vertical and horizontal positioning to be easily performed by roof and gutter workers alone, and in a short period of time.
Another object of the present invention is to provide a roof gutter that has a good appearance, has a small number of parts, and has a simple structure.

[Means for solving problems]

The roof gutter according to the present invention has a bottom sloped in the longitudinal direction and has a thick gutter body with a flange protruding toward the eaves formed on the upper edge of the eave side rising part,
forming engaging portions at the lower part of the eave-side rising part and at the upper edge of the opposite-to-eave side rising part of the gutter body, and supporting and fixing the flange to a building component such as a main building along which the gutter body extends in the longitudinal direction; The engaging portions formed on the eave side edge and the anti-eave side edge of the exterior gutter made of elastic material are engaged and held by the engaging portion, respectively, so that the anti-eave side rising portion, the bottom, and the eave side of the gutter body are engaged with each other. The outer peripheral side of the lower part of the rising portion is covered with the exterior gutter.

[Effect]

As mentioned above, the roof gutter of the present invention has a flange formed on the upper edge of the rising part of the eave side, which protrudes toward the eave side,
Using a gutter body in which engaging parts were formed at the lower part of the rising part on the eave side and at the upper edge of the rising part on the anti-eave side, the flange was supported and fixed to a building component such as a main building along which the gutter main body ran in the longitudinal direction. , the flange is supported by the building component over its entire length, and the gutter body can be fixed in a stable state. Combined with the thick wall of this gutter body, it can be fixed in a stable state, and can be fixed in a stable state in both vertical and horizontal directions. The gutter body can be accurately installed in a predetermined position without adjusting the position.

In addition, the engaging parts formed on the eave side edge and the anti-eaves side edge of the exterior gutter that covers the gutter body from the outer circumferential side are engaged and held in the eave side rising part and the anti-eave side rising part of the gutter body, respectively. Therefore, by finely adjusting the engagement position of the exterior gutter to the gutter body, even if there is a slight error in the installation position of the gutter body, especially in the horizontal direction, the rising part of the gutter body on the anti-eave side, the bottom, and the eaves can be fixed. Coupled with the fact that the lower part of the side rising part is covered with the exterior gutter and is hardly visible from the outside, the above-mentioned error is not visible from the outside, and the appearance of the entire roof gutter can be improved.
As a result, compared to the conventional method shown in Fig. 5, the present invention can be easily constructed in a short period of time with high work efficiency by only roof and gutter workers. Since it does not require aggregates or supporting members, the number of parts is small and the structure is simple.
