DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves gutter structure capable of preventing deformation and falling off due to the impact of foreign matter, snowfall and the like, and enabling use in snowy areas.

[0002]

2. Description of the Related Art In a conventional eaves gutter, a gutter receiving rainwater is installed so as to open directly upward through a gutter fitting. Eaves gutters were hardly used for snowy areas. Furthermore, the eaves gutter for a snow area, which is rarely formed by one member, has a complicated shape.

[0003]

However, in this case, (a) falling leaves, dust and the like are unavoidable, and maintenance is troublesome. (B) Can not withstand snow loads and has a short service life. (C) It was necessary to enable the use of eaves gutters with simple construction even in snowy areas.

[0004]

According to the present invention, in order to eliminate such a drawback, a water transmission introducing member is formed as a separate member on the way from the eaves to the receiving gutter, and a Coanda effect is obtained by interposing a supporting member. An eaves gutter that exerts a teapot effect, allows rainwater to flow down to a predetermined place, prevents foreign matter from entering, prevents damage due to snow loads and impacts such as falling snow, and can be easily positioned just by setting it on a support member. It proposes a structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The eaves gutter structure according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic diagram showing an example in which an eaves gutter structure A of the present invention is used in an eave part, and a water transmission introduction member B, a water reception member C, and a support member D for supporting these members.
Are formed as separate members. As the roofing material E, commercially available roofing materials such as various types of metal roofs such as a horizontally long roof, and cement-based new tiles and clay tiles can be used.

FIGS. 2 and 3 are explanatory views in which respective components of FIG. 1 are extracted. As shown in FIG. 2, a water transmission introducing member B is a fixing piece 2 having an engagement groove 1 having a substantially U-shaped cross section. A rainwater reversing piece 3 having a lower end of the fixing piece 2 protruding outward in a semicircular convex shape; and an engaging piece 4 having an engagement groove 1 having a substantially symmetrical shape with the fixing piece 2 at the lower end of the rainwater reversing piece 3. Further, the water receiving member C can be used by rotating the water transmission introducing member B substantially 90 degrees clockwise. However, as shown in the figure, the water receiving member C has a square pipe shape opened upward and has a water inlet 5. And the bottom piece 6 bent into the square pipe shape
And an outer side wall 7 in which both ends of the bottom piece 6 stand upright at a right angle.
A fixing piece and engagement pieces 2 and 4 having substantially the same shape as those of FIG. Of course, in addition to this square pipe shape, a semi-circular, elliptical, or trapezoidal shape may be used as the water transfer introducing member B or the water receiving member C employing, for example, male fixing pieces, engaging pieces 2, 4, and the like.
Further, although not shown, a water transmission introducing member B and a water receiving member C composed of a plurality of members may be used. As a material, in addition to a color steel plate, various metallic materials, synthetic resin materials, inorganic fired materials such as ceramics, and cement materials are used, and are formed by extrusion, roll forming, bending, pressing, or the like.

FIG. 3 shows a supporting member D. The middle pillars 9 and 10 have a T-shaped cross section and have a male piece 8 formed in the above-mentioned engaging groove 1 so as to be insertable into the engaging groove 1 at the top, bottom, left and right. 1
A support member 13 in which 1 and 12 are orthogonal to each other and a base material α such as a nose cover
And a receiving member 16 having an L-shaped cross section having, for example, a receiving surface 15 which is screwed to the middle support 11 near the other end, for example. is there. As the above-mentioned support member D, an example of two members of the inner suspension type is shown, but it is also possible to use an outer suspension type support member D as shown in FIG. 9, or a single member or three or more members.

FIG. 4 is an explanatory view showing a case in which a conventional eaves gutter F is used in a snow-covered area. The snow gamma protrudes from the roof material E of the eaves, and protrudes into the eaves gutter F opened upward. In this example, the eaves gutter F as well as the eaves gutter G are deformed, and the fixture β is seen to be lifted. In this state, the function of the eaves gutter F is lost, and water leakage to the outside of the eaves gutter may be unavoidable and may not be used.

FIG. 5 shows a case where the water introduction member B is formed as shown in the figure to further improve the wetting property, and (a) a hydrophilic paint or a hydrophilic film 18 is applied on the substrate 17. Or affixed, (b) a fine groove 19
(C) Spraying silica sand 20 or the like, applying or adhering a hydrophilic paint or hydrophilic film 18 on the surface if necessary, and (d) projecting on the surface of the film 18 A plurality of ribs 21 may be formed. Of course, although not shown, the convex ribs 21 may be formed on the base member 17 itself. (E) shows an example in which the substrate 17 is provided with an embossed surface 22 having irregularities. Further, when plastics or the like are used as the raw material, similar effects can be obtained as long as a material that improves hydrophilicity such as an antistatic agent is incorporated. The characteristic of the hydrophilic material such as the hydrophilic paint or the hydrophilic film 18 is that, as shown in FIG. 7F, when the hydrophilic property is high, the contact angle θ between the contact surface and the water droplet r becomes small,
As shown in (g), as the contact angle θ increases, the water repellency increases. The range referred to as hydrophilicity is 0 ° ≦ θ ≦ 60.
°. When the contact angle θ is small, the contact area with the contact surface is large even if the volume of water is the same. When water flows on a slope, the larger the contact area, the greater the resistance and the lower the flow velocity. Therefore, it is difficult for rainwater to flow out from the eaves. And so on.

FIG. 6 shows a case in which the radius of the tip of the water introduction section B is variously changed, and FIGS. 6A to 6D show the case where the radius of the rainwater reversing piece 3 is gradually reduced. The radius R can take various values as described above, but better results are obtained if R> 20 mm. Also, (a) and (c) show a case in which a draining protrusion 24 is formed at the boundary between the rainwater reversing piece 3 and the draining upper surface 23, or the draining upper surface 23 is inclined as shown in (b) and (d), or a saw-toothed drainer. It can also be.
(E) to (k) show various changes in the shape of the rainwater reversal piece 3, (e) shows the strength of the reversal piece 3 double-folded and tightly folded, and (f) shows (e). In (g), the R portion of the rainwater reversing piece 3 is formed in a polygonal shape, and (h) is in (a), in which a plurality of draining projections 24 are formed in a semicircular shape. (I) shows that one or more inverted R-shaped concave portions 25 are formed in the R portion of
When one or more R's are formed, (j) forms a large obtuse inclined surface, so-called steep roof, and (k) forms a buffer recess 26 for temporarily decelerating rainwater flowing down from the eaves. (L) shows a vertical portion 3a formed on the rainwater reversing piece 3 and the draining upper surface 23 inclined slightly outward.

FIGS. 7A and 7B show a case where the main body 27 of the water receiving member C is variously changed. FIG.
Is a dovetail shape, (c) and (d) are trapezoidal shapes with equal or unequal sides, and (e) and (g) are bottom steps 6 with step-like steps 28.
(F) is a pot-shaped cross section 29.

Next, an example of construction of the eaves gutter structure according to the present invention will be briefly described. Now, as shown in FIG.
In order to carry out the above, members as shown in FIGS. Then, as shown in FIG. 1, the support member D is fixed to the base material α by the fixing tool β. The water transfer introducing member B and the water receiving member C shown in FIGS. 2A and 2B are sequentially locked to the fixed supporting member D. The eaves gutter G is completed by continuously performing the above steps in the girder direction. Although not shown, dedicated accessories can also be used for the connecting portion between the eaves gutters G, the valley portion, and the descending ridge portion.

Next, the operation of the eaves gutter structure according to the present invention will be further described. When the rainwater r is introduced into the rainwater reversing piece 3 of the water transmission introduction member B connected from the roofing material E as indicated by the one-dot chain line arrow in FIG. 1 and flows downward along the round shape, it is a characteristic of the fluid. Due to the Coanda effect and the teapot effect, it wraps around inward from the vertical line a, and falls downward at the boundary where it changes to the draining upper surface 23. In the vicinity of the vertical line a which covers this falling rainwater r within a margin, In addition, the water inlet 5 is located close to the draining surface 23.
, It is possible to collect all of the rainwater r flowing down. On the other hand, during the winter period in which the snow cover γ exists, the snow wrapping around the eaves naturally falls from the outer tip of the rainwater reversing piece 3 in the direction of the vertical line, so that the water receiving member C is not damaged. Needless to say, fallen leaves, dust and the like naturally fall like the snow cover γ, and hardly enter the water receiving member C from the water inlet 5. In addition, it is also possible to further improve the Coanda effect and the teapot effect by adding hydrophilicity to the roof material E.
