However, in the drainage structure described in Patent Document 1, the snow-stopping protrusion is the only part that prevents snow from entering, and there are items such as fallen leaves that do not disappear over time in this part. There was a problem in that when it became clogged, the drainage function was also lost. Further, Patent Document 2 does not have a function to prevent clogging caused by fallen leaves, etc., so there is a problem that the drainage function is impaired when fallen leaves etc. enter together with rainwater.

Therefore, the present invention can be easily applied to vertical roof structures such as various folded plate roofs because the members used in the present invention are easy to manufacture, and rainwater can be removed from eaves gutters and inner gutters without preventing clogs caused by fallen leaves, etc. The purpose is to propose a drainage structure that can lead to

The drainage structure of the present invention includes a vertical roof plate having a rising portion with both side edges of a face plate portion raised toward the front side, and a drainage member arranged on the back side thereof, and has a plurality of water guiding recesses, In the water guiding recess, a water guiding member having a guide portion that guides rainwater from the front side to the back side and an inlet opening in the depth direction is disposed on the water lower side of the face plate portion, and the water guiding member is provided. The lower mounting piece is arranged on the back side of the face plate part, and each of the pair of mounting inclined pieces provided on the water guiding member is arranged in an overlapping manner on the front side of the rising part. The pair of mounting inclined pieces and the rising portion are an overlapping part, the lower mounting piece and the face plate part are an engaging part, and the water guiding recess of the water guiding member is located above the drainage member. shall be.

The vertical roofing plate is a member for constructing a vertical roof such as a folded plate roof having a rising part where both edges of the face plate part are raised toward the surface side as described above, and is, for example, a seam-clamping type or a fitting type. Various types of roof panels are known, but are not particularly limited.

As mentioned above, the drainage member is a member disposed on the back side of the vertical roof board to drain rainwater, etc., and may have any shape as long as it can drain rainwater, and is generally used as a gutter. A U-shape, a semicircular shape, an angular shape (U-shape), etc. can be used.
In addition, regarding the installation of this drainage member, even if it is installed as a gutter member on a building frame etc. (the structure etc. has a configuration of a gutter receiver), as shown in the illustrated embodiment described later, hanging tools etc. It may also be installed in a suspended manner from the roof structure via the roof structure.
This drainage member (gutter member) may be located on the back side of the water guiding member (water guiding recess), and may be located on the back side of the vertical roof shingles or extending from the eaves of the roof. good.
As such a drainage member, a general-purpose product can be installed that takes into consideration the load (the weight of snowfall and rainwater, the materials of the roofing material, the gutter material, the plate thickness, the installation method, and the installation position). Note that this drainage member may be a continuous material or may be constructed by connecting a plurality of members as long as it does not cause water leakage or the like. There is no particular limitation on the material as long as it can drain rainwater in the length direction. Therefore, it may be a molded product of various metal plate materials or a hard resin molded product.

The water guiding member has a plurality of water guiding recesses, and the water guiding recesses include a guide portion that guides rainwater from the front side to the back side, and an inlet that opens in the depth direction. The lower mounting piece provided on this water guiding member is placed on the back side of the face plate, and each of the pair of mounting inclined pieces provided on this water guiding member is placed on the surface side of the rising part. By being arranged in an overlapping manner, the pair of mounting inclined pieces and the rising portion become an overlapping part, and the lower mounting piece and the face plate part become an engaging part .
This water guiding member is a member that guides (falls) rainwater etc. flowing through the face plate portion to the drainage member, and prevents snowfall flowing together with rainwater etc. from accumulating inside the drainage member, and fallen leaves etc. from entering and accumulating. play a role in prevention.

In addition, as mentioned above , the engagement receiving part that is engaged with the lower end (eaves edge) of the face plate part of the vertical roof board is, for example, as in the illustrated embodiment described later, when the face plate part of the vertical roof board is By forming a U-shaped notch hole (=first embodiment) or forming a rectangular hole (=second embodiment) in a superimposed manner to supplement the water guiding member, Rainwater, etc. flowing through the face plate of the vertical roof board is guided onto the water guiding member, and then drained by the drainage member on the back side. The water guide member in these examples is attached to the face plate portion in an overlapping manner, so it is formed in a flat plate shape.
Alternatively, without forming a notch hole or a rectangular hole in the vertical roofing board itself, a water guide member formed in a shape similar to that of the vertical roofing board is connected in parallel to the water lower end of the face plate part. (=Third Example).

Regarding the installation of the water guide member to the vertical roofing board, as described above , in order to ensure stable attachment to the vertical roofing board, it is installed along the left and right edges of the flat plate along the rising pieces of the vertical roofing board. In order to ensure that rainwater flowing through the face plate is guided onto the water guide member by providing a mounting slope piece as an overlapping part , an engagement receiving portion at the lower water end of the face plate is attached to the water upper edge of the flat water guide member. ) is provided with a lower mounting piece that runs along the back side of the handle as an engaging part .

Each of the plurality of water guide recesses formed in the water guide member has a guide portion that guides rainwater from the front side to the back side, and an inlet that opens in the depth direction. Since this inlet is formed at the lowest end of each water guide recess, the guide portion is sloped in the depth direction to guide rainwater.
As described above, the "depth direction" means the thickness direction of the water guide member itself, that is, the depth direction, and the inlet is opened in the depth direction.

When this water guide recess is arranged in an inclined manner along the flow direction, the guide portion is located above the water and the inlet is formed at the lower end of the water, that is, the inlet is oriented in the flow direction. It is desirable to arrange the water guide recesses so as to face each other directly.
This water-conducting recess can be formed using a combination of slit processing that corresponds to the inlet and press processing that uses the slit as an edge (processing that forms a concave shape), so it is necessary to form the slit width in the direction that intersects with the flow direction. Accordingly, the introduction port can be directly opposed to the flow direction, and a desired guide portion and introduction port can be formed.

The introduction port refers to the part that introduces rainwater etc. into the interior of the drainage member, and as mentioned above, it is open in the depth direction and faces the side in the depth direction, that is, the side below the water. It is formed like this.
There is a suitable range for the depth and width of this inlet, which will be described later. If it is too small, surface tension will act to form a water film, making it impossible to drain water sufficiently; if it is too large, the amount of drainage will be large, but fallen leaves and It becomes easy for dirt etc. to become clogged (easily introduced into the gutter material).

The guide portion may have the shape of an inclined curved surface directed toward the inlet formed at the lowest end of the water guide recess, or may be formed of a plurality of inclined planes, and may have a horizontally long rectangular shape in plan view, or may have a horizontally elongated rectangular shape, or may have an inclined curved surface toward the inlet formed at the lowermost end of the water guide recess. It may be a horizontally elongated shape with arcuate corners, and is not particularly limited. Note that the term "horizontally long" means that the dimension in the direction intersecting the flow direction (horizontal direction) is long.

The water guide recess with such a configuration is created by combining (simultaneously performing) slit processing with the width of the inlet and press processing (processing to form a concave shape) using the slit as the lower end. An introduction port can be formed. Therefore, this water guide member is molded from metal, synthetic resin, or other materials, but there is no particular limitation on the material as long as it can be processed as described above, and typically it is made of metal, synthetic resin, or other materials. Known metal materials such as decorative steel plates, laminated steel plates, plated steel plates, stainless steel plates, aluminum alloy plates, titanium alloy plates, and copper plates with a thickness of about 0.4 to 1.6 mm can be used.

As described above, in the water guiding member of the present invention, a plurality of water guiding recesses are arranged, each of which has an inclined guide portion provided with an inlet opening in the depth direction at the lower end thereof.
In this water guide recess, an experiment was conducted based on the above-mentioned knowledge regarding the depth interval of the inlets, and it was confirmed that the depth interval is preferably 3 to 5 mm. When the depth interval exceeds 5 mm, it has been confirmed that fallen leaves and debris enter with rainwater, and when the depth interval is less than 3 mm, the surface tension of rainwater acts on the inlet (opening edge) (forming a water film). ), it was confirmed that the rainwater did not function as an inlet, and rainwater could not be introduced quickly and flowed down (the introduction of rainwater to the drainage member was impaired). In other words, by forming the depth interval of the inlets to be 3 to 5 mm, it is possible to prevent the intrusion of fallen leaves, dirt, etc., and to quickly introduce rainwater into the flow channel of the drainage member.

Furthermore, when the water guide recesses are arranged in a staggered manner along the water gradient direction, the water guide recesses in the current stage are located on the lower side of the width of the distance between the water guide recesses adjacent in the left and right direction in the upper stage in the flow direction. Since the rainwater that has passed through the water guide recesses in the upper stage can be reliably collected in the water guide recesses in the upper stage, the rainwater can be introduced into the inside of the gutter material more reliably.

Note that the arrangement of the drainage member on the back side of the vertical roof board is not particularly limited to its structure; for example, it may have a structure in which the lower surface is supported (taken out) with a support fitting fixed to the structural material. However, a structure in which the upper end of the side surface is hung (suspended) using a hanging metal fitting or the like may also be used.
