Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an eaves structure that can prevent rainwater from entering the eaves, has an extremely simple structure, and can be provided at a low cost.

[Conventional technology and its problems]

Conventionally, metal folded plate roofs have been widely used. This folded plate roof includes a folded plate roof in which mountain-shaped portions and valley-shaped portions continue alternately, and is constructed by overlapping the mountain-shaped portions of adjacent folded plate roof plates with each other.

Rainwater often enters between the mountain-shaped parts of the overlapped parts due to capillary action, and sealing materials, adhesives, etc. are sometimes used to prevent this, but the number of steps during construction is There were problems such as an increase in construction efficiency, poor construction efficiency, and high construction costs.

[Means for solving problems]

Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor developed the present invention, in which the mountain-shaped portion of a folded roof plate, in which the mountain-shaped portion and the valley-shaped portion continue alternately, At the overlap point of the eaves of a folded roof that overlaps with the chevron-shaped part of the folded roof plate and repeats this process one after another, the tip of the lower chevron-shaped part is inward from the tip of the upper chevron-shaped part. By forming the eaves structure in such a way that it is positioned at the eaves, it is possible to prevent rainwater from entering the eaves, and the structure is extremely simple and can be provided at low cost, thus solving the above-mentioned problems.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 8.

A is a folded roof plate in which a mountain-shaped portion 1 and a valley-shaped portion 2 are continuous in the width direction and formed to have an appropriate length in the longitudinal direction. The mountain-shaped portion 1 and the valley-shaped portion 2 are separated by the neutral plane of the folded roof sheet A. That is, the portion above the neutral plane is called a mountain-shaped portion 1, and the portion below the neutral plane is called a valley-shaped portion 2. The mountain-shaped portion 1 has a trapezoidal mountain cross section, and the valley-shaped portion 2 has a bottomed V shape.

In addition, the folded roof plate A has mountain-shaped portions 1, 1 formed on both sides of one valley-shaped portion 2, or a plurality of mountain-shaped portions 1 and valley-shaped portions 2 are formed in succession alternately. It is.

In the width direction of the folded roof plate A, the folded plate roof plate A,
A is installed side by side, and the mountain-shaped parts 1, 1 of adjacent folded plate roof plates A and A are overlapped, and these are repeated one after another to form a folded plate roof.

In this way, the folded plate roof is constructed by superposing the adjacent mountain-shaped parts 1, 1 of the folded plate roof plates A, A, ..., which are installed together, and therefore,
The chevron-shaped portion 1 on one side of the folded roof plate A in the width direction is located on the upper side at the overlapping portion, and the chevron-shaped portion 1 on the other side is located on the lower side at the overlapping portion.

At the point where the eaves of the folded plate roof overlap, the tip of the lower chevron-shaped portion 1 (including the top 1a of the chevron-shaped portion 1) is located inward (indoor side) from the tip of the upper chevron-shaped portion 1. The eaves structure is constructed in this way (see Figure 8).

There are various examples of this eaves structure, the first of which is
As shown in FIGS. 1 and 2, in this embodiment, at the overlapping location, the tip of the chevron-shaped portion 1 on either side of the lower folded roof plate A (on the eaves side) is directed inward and upward. It was once formed in a sloping shape. At this time,
A portion of the valley-shaped portion 2 that is continuous with the mountain-shaped portion 1 is also formed in an inclined shape upwardly inward from the lower end.
In some cases, only the mountain-shaped portion 1 is formed to be inclined inwardly and upwardly.

In the second embodiment, an inclined edge 3 facing downward is integrally formed at the tip of the chevron-shaped portion 1 of the first embodiment (see FIG. 3). This inclined edge 3 is
It is formed on the entire surface of the folded roof plate A on the eaves side in the width direction, if necessary. Further, the upper and lower chevron-shaped portions 1, 1 may be provided with inclined edges 3, 3, respectively, at the overlapping location (see FIGS. 3 and 4).

In the third embodiment, as shown in FIGS. 5 and 6, from the inner end of the top part 1a of the mountain-shaped part 1 of the folded roof plate A that is on the lower side at the overlapping part, the rearward direction is shown in FIGS. It is formed in an inclined shape (6th
(See the dashed line in the figure).

In the fourth embodiment, the tip of the chevron-shaped portion 1 of the folded roof plate A, including the top portion 1a, is notched in the shape of a hook (see FIG. 7).

In the above first to fourth embodiments, the overlapping points of the folded plate roofs are such that the tip of the lower chevron-shaped portion 1 is located inward from the tip of the upper chevron-shaped portion 1. There is.

In the figure, 4 is a side wall, 4a is an exterior material, 4b is an interior material,
5 is the structural material of the main building, 6 is the metal door fitting, 7 is the metal door, 8 is the metal fitting, 9 is the arabesque material, 10 is the ceiling board, 1
1 is a heat insulating material.

[Effect of idea]

In the present invention, the mountain-shaped portion 1 of the folded roof plate A, in which the mountain-shaped portions 1 and valley-shaped portions 2 continue alternately, is superimposed on the mountain-shaped portion 1 of the adjacent folded plate roof plate A, and this is By creating an eaves structure in which the tip of the lower chevron-shaped part 1 is located inward from the tip of the upper chevron-shaped part 1 at the overlapping part of the eaves of the folded plate roof that is successively and repeatedly constructed. Firstly, it can prevent the infiltration of rainwater, etc., and secondly, it has a simple structure and can be provided at a relatively low price.

To explain these effects in detail, the present invention has the following effects:
A folded plate roof is formed by overlapping the mountain-shaped parts 1, 1 of the adjacent folded plate roof plates A, A, ... of the attached folded plate roof plates A, A, ..., and at the eaves part of the overlapped part, The tip of the lower chevron-shaped part 1 is the upper chevron-shaped part 1
Specifically, as shown in Figure 8, which is a schematic cross-sectional view in the longitudinal direction of the overlapping part, the upper and lower chevron-shaped parts This is a configuration in which only the top portions 1a, 1a of 1, 1 are shown. In this case, the top part 1 of the upper chevron-shaped part 1
Rainwater drops fall from the tip of a. At this time,
If the tip of the upper chevron-shaped portion 1 and the tip of the lower chevron-shaped portion 1 coincide, water droplets will enter between the upper and lower chevron-shaped portions 1 and 1 due to capillary action, This can cause indoor rain leaks and corrosion of the folded roof panels A, but the present invention completely eliminates these inconveniences, and water droplets at the eaves do not reach the lower mountain-shaped portion 1. It can reliably prevent water from falling and flooding due to capillary action.

In addition, although it has good waterproof properties as described above, its structure consists only of folded roof panels A, A,..., and sealing materials, adhesives, etc. There is no need to intervene between the part 1 and the lower chevron-shaped part 1, so the roof can be constructed in the same manner as a conventional folded plate roof, and an extremely low-cost eaves structure can be provided.

Furthermore, as shown in Fig. 3, if a sloped edge 3 is formed at the tip of the folded roof plate A on the eaves side, water droplets can enter the indoor side of the folded plate roof from the attic surface even during strong winds and rain. It has the effect of preventing this.
