Description

  The present invention relates to an eaves joint and an eaves connection structure.

The eaves can be a straight section or corner of the eaves of a house or the like by connecting a plurality of molded or cut pieces with a predetermined length dimension in a straight line by an eaves joint or in a substantially orthogonal direction. Installed in the department.
Conventionally, as a connecting structure of eaves eaves, two eaves eaves joints are arranged inside each end portion of the upstream eave eave and the downstream eave eave arranged adjacent to each other in the longitudinal direction. A method of connecting the two is known. Inside this eaves joint, a rainwater flow path is formed, and the rainwater in the upstream eaves wall flows through the rainwater flow path of the eaves joint to the downstream eaves side. ing.

  However, when the eaves joint is arranged inside the eaves, there is a step corresponding to the thickness of the bottom of the eaves joint between the inner bottom of the eaves and the inner bottom of the eaves joint. If it does so, since rainwater may remain in the level | step-difference part between the eaves joints in the eaves of an upstream side, there was a possibility that algae and moss might grow with the remaining rainwater.

  Therefore, the bottom of the eaves joint is provided with a hole that opens to both eaves side, so that residual rainwater in the upstream eaves side is sucked into the hole by capillary action and flows to the eaves side on the downstream side. Have been proposed (see, for example, Patent Document 1).

Hereinafter, an eaves joint according to an embodiment of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the eaves rod connection structure X of the present embodiment includes an eaves rod joint 1, an upstream eave rod 2, and a downstream eave rod 3.

The eaves joint 1 is disposed across the ends 4 and 5 of the eaves 2 and 3 and forms a flow path of rainwater flowing from the upstream eaves 2 toward the downstream eaves 3. A saddle-like body 6 having a substantially U-shaped cross section is provided. On the inner bottom surface 8 of the bottom plate 7 of the bowl-shaped body 6, there is a flow path of residual rainwater that continues from the upstream edge 9 of the inner bottom surface 8 to the downstream edge 10 of the eaves 2. A certain groove 11 is formed.
In addition, the code | symbol 12 in a figure shows the bending type eaves joint used for the exit corner or entrance corner of an eaves tip. The present invention can also be applied to the eaves joint 12 of this bent type.

As shown in FIG. 2, the eaves joint 1 of the eaves joint 1 has a substantially U-shaped cross section and a polygonal shape, and the internal space serves as a rainwater flow path.
The saddle-like body 6 has a rear side plate 13 disposed close to a nose cover plate (not shown) of the building and opposed to the nose cover plate, a front side plate 14 spaced from the rear side plate 13, and a rear side plate 13. And a bottom plate 7 for connecting the lower end of the front side plate 14 to the lower end of the front side plate 14.

The concave groove 11 is formed in the intermediate portion in the width direction on the inner bottom surface 8 of the bottom plate 7. The rear side plate 13 is provided with an uneven portion 15, a tongue piece 16, and the like.
As shown in FIG. 3, the thickness of the bottom portion 17 of the concave groove 11 is thinner than the portions on both sides thereof. On both side surfaces of the concave groove 11, inclined surfaces are provided that are inclined in a direction spreading toward the outside.

  In the present embodiment, the groove 11 is linearly formed with a predetermined width dimension. Here, the width dimension of the concave groove 11 is formed to be about ¼ of the width of the inner bottom surface 8 in the direction orthogonal to the direction in which rainwater flows, but it may be ¼ or less or ¼ or less. The thickness of the bottom portion 17 of the concave groove 11 is formed to be approximately ½ of the thickness dimension of both sides of the concave groove 11, but may be ½ or less or ½ or more.

  The upstream eave ridge 2 and the downstream eave ridge 3 in FIG. 1 are formed in a substantially U-shape having a polygonal cross section having an internal space. The eaves 2 and 3 have a rear side plate 18, a front side plate 19, and a bottom plate 20, similarly to the eaves joint 1. In the case of the bent type eaves joint 12, it is formed in an L shape as a whole, and its cross section is formed in a polygonal U shape.

  Next, the operation of the eaves joint 1 will be described. As shown in FIG. 1, when connecting the eave ridge 2 on the upstream side and the eave ridge 3 on the downstream side, one end of the eaves ridge joint 1 is fitted inside the end 4 of the upstream eave ridge 2. Then, the other end portion of the eaves joint 1 is fitted inside the end portion 5 of the eaves cage 3 on the downstream side. Thereby, the upstream eave ridge 2 and the downstream eave ridge 3 are connected, and the rainwater in the upstream eave ridge 2 flows through the eave ridge joint 1 to the downstream eave ridge 3 side.

  Thus, in the state where the upstream eave ridge 2 and the downstream eave ridge 3 are connected by the eave ridge joint 1 arranged inside the both eave ridges 2 and 3, the upstream eave ridge 2 A step is formed on the inner surface of the end portion by the thickness of the bottom plate 7 of the eaves joint 1. Therefore, according to the conventional technique, rainwater tends to remain in the stepped portion in the eave ridge 2 on the upstream side.

According to the eaves joint 1 of the present embodiment, since the bottom plate 7 is formed thin in the recessed groove 11, rainwater remaining on the stepped portion in the upstream eave basket 2 is caused by the recessed groove in the eaves joint 1. 11, it is easy to be smoothly flowed to the eave ridge 3 side on the downstream side. Therefore, it is possible to prevent the algae and moss from growing on the stepped portion due to the rainwater remaining in the stepped portion in the eaves bowl 2 on the upstream side.
Moreover, since the ditch | groove 11 does not absorb rainwater by a capillary action like the conventional eaves joint, the cross-sectional area (flow area of residual rainwater) can be made comparatively large. Therefore, it is possible to prevent the concave groove 11 from being blocked with sand or the like.

  Next, modifications 1 to 4 of the eaves joint 1 will be described. In the following description, the same components as those in FIGS. 2 and 3 are denoted by the same reference numerals, and detailed description thereof is omitted.
