Description

  The present invention relates to a roof having a rain gutter, and particularly to a rain gutter having a snowfall guide cover attached thereto.

  On roofs installed on terraces, balconies, carports, etc., rain gutters are installed along the bottom edge of the roofing material. There are two types of rain gutters, one made of synthetic resin and one made of metal, and one made of metal is formed integrally with the front frame.

  Usually, the rain gutter is opened upward. For this reason, in cold regions with snowfall, a large amount of snow has entered the gutters as the snow that has fallen on the roof slides down the top surface of the roofing material, and accumulates above the gutters and accumulates on the top of the gutters. However, the rain gutter was deformed and the gutter was damaged due to freezing and expansion of snow.

In order to prevent the rain gutter from being deformed or damaged due to snow on the roof, it is necessary to provide a snow fall guide cover for guiding the falling snow to the outside of the gutter on an inclined surface near the gutter installation portion of the roof. 1 disclosed.

  However, the known snowfall guide cover is a horizontally long member, and is attached by screwing to the rafter cover at a position away from the rain gutter. For this reason, it is difficult to accurately perform the positioning at the time of mounting, and it takes time for construction, and it is not easy to take the horizontal level accurately, so the appearance may be impaired. In addition, the known snowfall guide cover is curved so as to project from the roof material to the upper center of the rain gutter and tries to guide the snowfall. Therefore, when the snow cover has a high moisture content, Since it fell while sticking to the surface of the snowfall guide cover, it entered the rain gutter, and there was a problem that the effect of preventing the rain gutter from being deformed or damaged was not necessarily exhibited.

  The present invention has been made to solve the above problems. In other words, it is easy to install the snowfall guide cover at the correct position, and it is possible to reliably prevent the snowfall from entering the rain gutter and to prevent the rain gutter from being deformed or damaged. The purpose is to do.

In order to achieve the above object, a roof according to the present invention includes a snowfall guide cover that covers an upper surface of an opening of a rain gutter and guides snow falling from the upper surface of the roof material downward without entering the gutter. The snowfall guide cover is attached with leaving a gap through which rainwater flowing down the top of the material can flow into the rain gutter, and the upper end of the rising wall on the opposite side of the rain gutter roof material at the one end in the width direction. The first engaging portion that engages with the other end portion in the width direction has an edge that contacts the upper surface of the roofing material at a position closer to the one end portion side than the other end portion. A second engaging portion that engages with the provided roof material pressing portion has a recessed groove that opens upward between the first engaging portion and the second engaging portion, respectively, and the lower end of the adjacent rafter cover The rainwater flowing down the top surface of the roof material between the rafter covers directly between the parts directly reaches the rain gutter. Is characterized by with a gap flowing into the gutter through the groove is intended to be attached to the front frame (claim 1).
With the above configuration, when it rains, rain that has fallen on the roof flows into the gutter from the gap and is drained. During snowfall, the snow sliding down the top surface of the roof material is reliably prevented from entering the rain gutter by the snow fall guidance cover, and is guided outside and falls outside the top surface of the rain gutter opening.
Also, when attaching the snowfall guide cover, engage the first engaging part at one end with the upper end of the rising wall on the opposite side of the gutter roof material and the edge of the other end on the top surface of the roofing material. By engaging the second engagement portion with the roof material pressing portion in the contacted state, the second engagement portion can be easily attached to an accurate position. The rain that falls on the roof flows directly into the rain gutter between the lower ends of the adjacent rafter covers, or once flows into the ditch and then flows into the gutter from the ditch. Accordingly, rainwater drainage is ensured.

Yes. The connection between the girders 3 and the rafters 8 is configured to be performed at an arbitrary position in the longitudinal direction of the rafters.

  As shown in detail in FIG. 2, the front frame 7 has a hollow portion 7 a for providing a required strength, and a rain gutter 7 b opening upward on the opposite side of the rear frame 6 of the hollow portion. It is integrally formed. At the upper end of the rising wall 71 (hereinafter referred to as the first rising wall) far from the rear frame 6 of the gutter 7b, as shown in FIG. Is provided. Further, a roof material pressing portion 74 extending in the direction of the rear frame 6 is formed at an upper end portion of the rising wall 73 (hereinafter referred to as a second rising wall) on the side close to the rear frame 6 of the rain gutter 7b, and the hollow portion 7a. An insertion groove 76 for inserting the lower end portion of the roofing material 9 is formed between the upper surface wall 75 and the rear frame side end portion of the upper surface wall 75 is bent upward, and the bending portion 77 is inserted into the insertion groove 76. A cushioning material 12 that supports the roofing material 9 is fitted. Reference numeral 13 in FIGS. 1 and 2 denotes an L-shaped connecting bracket that connects the rafter 8 and the front frame 7.

  A snowfall guide cover 14 as shown in FIGS. 2 and 3 is attached to the rain gutter 7b opened upward in FIG. 1 so as to cover the opening surface of the gutter. The snowfall guide cover 14 has a substantially downward opening C-shaped first engagement portion 141 at one end in the width direction, that is, at the end far from the rear frame 6. The first engagement portion 141 has an abutment portion 141a and a locking portion 141b, and the upper end portion of the first rising wall 71 of the rain gutter is slightly and gently fitted to this, with the upper end portion as the center. The other end portion of the snowfall guide cover 14, that is, the end portion on the side close to the rear frame 6, can be rotated in a direction approaching the roof material pressing portion 74 of the front frame 7 and in a direction away therefrom.

  In addition, the snowfall guide cover 14 has an edge 142 for closely contacting the upper surface of the roofing material 9 at the other end in the width direction, that is, the end near the rear frame 6. A concave groove 143 that opens upward is provided at an intermediate portion between the first engagement portion 141 and the end edge 142, and an L-shaped bent edge is formed between the bottom of the concave groove 143 or between the bottom portion and the end edge 142.

That is, first, as shown in an enlarged view of the first engagement portion 141 of the snowfall guide cover 14 in a circle A in FIG. 4, the locking edge 72 is included at the upper end portion of the first rising wall 71 of the rain gutter. The snowfall guide cover 14 is rotated toward the roof material 9 with the upper end portion of the first rising wall 71 as a center, and the edge 142 is brought into contact with the upper surface of the roof material 9 while being fitted. Next, since the first engaging portion 141 is slightly loosely fitted to the upper end portion of the first rising wall 71, the snowfall guide cover 14 is attached to the end edge 142 and the second engaging portion 144. While pressing against the upper surface of the roof material 9, it is slid downward along the gradient of the roof material, and the tip of the roof material pressing portion 74 of the front frame 7 is inserted into the groove of the second engaging portion. As a result, as shown in FIG. 2, the second engagement portion 144 engages with the roof material pressing portion 74 and at the same time, the first engagement portion 141 engages with the locking edge 72 at the upper end portion of the first rising wall 71. The snowfall guide cover 14 is fixed to the front frame 7.

  In the preferred embodiment, after the snowfall guide cover 14 is fixed to the front frame 7 as described above, the screw 15 is screwed from the bottom of the groove 143 as shown in FIG. 2 Close to the upper end of the rising wall 73. Thereby, the snowfall guide cover 14 moves upward in the gradient of the roof material 9, that is, the first engagement portion 141 and the second engagement portion 144 are the locking edge 72 and the tip of the roof material pressing portion 74, respectively. Therefore, the snowfall guide cover 14 is reliably prevented from coming off the front frame 7.

  As shown in FIG. 5, the snowfall guide cover 14 is shorter than the distance between adjacent rafter covers and is attached to the center between rafter covers. Therefore, the opening surface of the rain gutter 7b is opened upward between the both ends of the snowfall guide cover 14 and each rafter cover. Further, both end portions of the concave groove 143 of the snowfall guide cover 14 communicate with the rain gutter 7b. Therefore, as shown in FIG. 6, part of the rain R that has fallen on the top surface of the roof is rain gutter 7b directly from the top surface of the roof material, and the remainder is rain gutter from the top surface of the roof material through the groove 14 of the snowfall guide cover 14. Flows into 7b.

  As illustrated in FIG. 1, the rainwater flowing into the rain gutter 7 b is connected to the drain 16 attached to the gutter, the horizontal gutter 17 connected thereto, and the vertical gage attached to the pillar 1. The water is drained to the ground G via the dredge 18.

  Further, when the snow falling on the roof to which the snowfall guide cover 14 is attached slides down the top surface of the roof material, as shown in FIG. Since it covers the opening surface of the door, it is prevented from entering the rain gutter, and as shown by a thick line in FIG. 7, it is guided beyond the snowfall guide cover 14 and smoothly falls downward. . Therefore, the subsequent snowfall is also slid without being blocked by the snow accumulated in the gutter. Therefore, the rain gutter formed of a thin plate having a relatively low strength such as synthetic resin or aluminum is reliably prevented from being deformed or damaged by snow entering the gutter.

  FIG. 8 shows an example of a roof TR2 having a small roof slope. FIG. 9 shows the structure of the rain gutter 7b of such a roof and the snowfall guide cover 14 attached to the gutter.
