Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an eaves structure of a building.

(Prior Art) In recent years, the effects of acid rain cannot be ignored, and the environment surrounding eaves gutters has changed. At the bottom of the eaves gutter,
Dust and other substances are deposited in layers, which receive dew at night, so they are always moist.

When acid rain falls there, it becomes a wet acidic mat. Furthermore, each time it rains, the acidic mat is replenished with acid components, so it is constantly in contact with a highly reactive and highly concentrated acidic mat. This has led to the recent phenomenon of holes forming in copper eaves gutters (Asahi Shimbun, March 18, 1990, p. 31).

On the other hand, most of the conventional building materials commonly used for eaves, such as eaves gutters, fascias, and soffit ventilation holes, have a single function, and their construction requires assembled and installed in stages.

In such a step-by-step construction method using single-functional building materials, it is difficult to simultaneously make fundamental improvements in all elements such as functionality, workability, durability, aesthetics, and reduction in the number of building materials. In view of this, the applicant of this application has previously proposed a composite functional building material for eaves [Unexamined Patent Application Publication No. 63-118] in which the individual functions of the individual functional building materials described above are integrated into one.
94058] was proposed.

However, eaves structures constructed using such multi-functional building materials are difficult to disassemble, which can cause inconvenience when repairs or renewal become necessary due to the effects of acid rain, etc. I was afraid.

For this reason, it is desirable that at least the part of the eaves gutter, which is exposed to harsh environments, be constructed so that it can be repaired or renewed.

Therefore, in Utility Application No. 1-118238, the applicant of this application used a separable eaves gutter type fascia that made it possible to repair or update the eaves gutter by separating the eaves gutter part from the composite functional building material of the previous application. We proposed that the system be structured as follows.

(Problems to be Solved by the Invention) However, in the above-mentioned configuration, the conventional eaves gutter is exposed, so there is a problem in that the aesthetic appearance cannot be improved. Further, in claim 6 of the above application, in which the eaves gutter is attached to the water channel part using a fascia with a water channel support, and the eaves gutter is configured as a multilayer eaves gutter, the eaves gutter is not exposed. However, overall it was not satisfactory.

In view of the above, this application provides a more satisfactory eaves structure that excels in performance and aesthetics, is repairable and upgradable, and can cope with acid rain expected in the future.

(Means for Solving the Problem) That is, in the present invention, in an eaves structure in which the eaves gutter is composed of a water channel member and a water channel support that supports the water channel member, the water channel support is continuous over the entire length of the water channel member. The eaves gutters should be constructed in multiple layers.

Further, in the eaves structure configured using a fascia with a waterway support in which the fascia 1] constitutes the waterway support 1], the fascia and the waterway support are configured to be freely assembled.

When the waterway member and the waterway support are configured in multiple layers over the entire length thereof, the waterway support has a structure in which the fascia and the waterway support are freely assembled as shown in the following. It is effective to use a fascia.

Furthermore, the above-mentioned fascia with waterway support has a structure in which an attachment connection part for attaching to the eaves and a soffit connection part forming part 1 of the soffit are formed parallel to the length direction. It is effective to connect the above-mentioned mounting connection to the eave through a fixed concealment.

Furthermore, it is preferable that the above-mentioned fascia with waterway support is fixed to the eaves via a mounting fitting that engages the mounting connection portion thereof.

In addition, an eaves structure is constructed in which one end of the eave ceiling is connected to the eaves gutter, and a large number of through holes are provided on the eaves gutter side of the connection part, and the eaves soffit is connected to the eaves gutter. Ventilate through holes.

In addition, the eave structure is configured such that one end of the eave ceiling is connected to the eaves gutter, and the gutter that connects the eaves gutter and the downspout is directed approximately horizontally from the side of the eaves gutter. The structure is such that the gutter is hidden by the soffit.

Further, it is preferable to use a fascia with a waterway support provided with a door mounting groove, and to close the space between the fascia and the roof material by the door attached to the door mounting groove.

(Function) The water channel support according to claim 1 corresponds to a state in which a large number of conventional eaves gutter attachment fittings are connected continuously over the entire length of the eaves gutter, and the water channel member is similar to the conventional one. Since it corresponds to the eave gutter of , a multi-layered eave gutter can be obtained. Moreover, since the water channel member can be treated in the same way as a conventional eaves gutter, it is not only possible to repair or update it, but also to be easily attached and detached. In such removable multi-layered eaves gutters, the water channel members can be selected from materials with excellent corrosion resistance regardless of rigidity, and the water channel supports can be selected from materials with excellent corrosion resistance. This makes it possible to select from among materials with superior rigidity and formability. Therefore, it is possible to divide the functions of the eaves gutter, and it is possible to configure the eaves gutter by combining materials that are most suitable for each purpose, thereby obtaining eaves gutter made of a composite material that is optimal for each environment. Moreover, since the eaves gutter made of the composite material of the present invention can be configured so that the composite material can be detached, the waterway support can be a permanent member that lasts for one generation of the building, and the waterway member can be replaced as a consumable member depending on the situation. It can be configured as such, and will be able to adequately deal with acid rain.

On the other hand, in the fascia with a waterway support according to claim 2, the fascia part and the waterway support part are constructed so that they can be assembled freely, so that it can be easily assembled not only during new construction but also during repair or renewal. It becomes possible to work in a disassembled state. Therefore, the work becomes easier, and construction can be easily carried out in any complicated place. Then, it becomes possible to repair or update only the waterway part with severe environmental conditions by separating it, that is, to repair or update the waterway part while leaving the fascia part related to the main structure of the building as it is. The parts are not necessarily required, and even if they are omitted,
It is configured to be able to adequately deal with unresolved potential problems such as acid rain.

Furthermore, the waterway member according to claim 3 is configured to be further disassembled from the waterway support body which is configured to be disassembled from the fascia part constituting the main body of the building, so it can be disassembled in two stages. This not only makes repair and renewal work easier, but also allows multilayering in complex areas. Therefore, it is possible not only to make the rectangular machine multi-layered, but also to make it possible to make multi-layered parts such as sluices installed in the lateral direction.

Moreover, since the fascia according to claim 4 connects the eaves and the soffit via the fascia with a water channel support,
The eaves are covered with metal material, which not only protects them from direct sunlight and wind and rain, but also prevents wood from being exposed from the eaves, significantly improving fire protection performance.

Furthermore, the mounting fittings according to claim 5 can be fixed to the rafters, and since the rafters are stronger structures than the field boards, the above-mentioned attachment connection part can be fixed directly to the field boards, etc. Greater mounting strength can be obtained compared to the case where Therefore, the durability of the installation is improved, and safety against storms, snow, earthquakes, etc. is improved.

Further, since the through hole in claim 6 is provided on the eaves gutter side of the connecting portion between the eaves gutter and the eaves ceiling, the inside of the eaves can be uniformly ventilated from the most extreme position of the eaves. Furthermore,
Even in the unlikely event that rainwater leaks from the eaves gutter, it will be discharged from the through holes on the eaves gutter side, so it will not wet the inside of the eaves or the eaves ceiling itself. Furthermore, since it is superior in decorativeness, the aesthetic appearance is improved.

Moreover, since the service gutter according to claim 7 is provided facing substantially in the horizontal direction, there is no member that intersects with the eaves gutter in the right angle direction. Therefore, the eaves have a clean horizontal-letter configuration, and the aesthetic appearance of the eaves is dramatically improved.

Further, by using the side door according to claim 8, the fascia with waterway supports can be vertically attached regardless of the slope of the roof.

(Example) The first example shown in FIG. 1 is an example related to claims 1 and 5, and will be explained using an example of a round gutter that is most suitable for a Japanese-style house with exposed rafters.
