Description

  The present invention relates to an eaves tip ventilation structure in which an eaves passage for performing ventilation between the attic and the outside air is formed while decorating the eaves of a roof, and a decorative member such as a windbreak plate or a nose cover used in the eaves tip ventilation structure.

  In conventional eaves-end structures for eaves ceiling mounting, etc., a structure having a ventilation structure is required in order to prevent attic deterioration and legal requirements. As an example of an eaves-end structure having a ventilation structure, one disclosed in Patent Document 1 is known.

  The eaves tip ventilation structure described in Patent Document 1 includes a windbreak plate that is formed in a substantially L shape, and has a plate-shaped breakage plate main body, and a protruding portion that protrudes from the lower side of the windbreak plate main body toward the side. Are attached to the overhanging portion, and a ventilation hole is provided on the overhanging portion.

  Moreover, the eaves tip ventilation structure described in Patent Document 2 has a base material attached to the ends of the rafters, the eaves top and the field edge, and a ventilation trunk edge attached to the eaves top edge and the lower surface of the base material. Then, by fixing the eave heaven to the ventilator rim, a gap corresponding to the thickness of the ventilator rim is provided between the rim of the eave heaven and the base material and the eave heaven. In addition, a ceramic eaves cover member with a jaw fixed to the base (hereinafter referred to as a cover member with a jaw) is configured in an L-shape, and a jaw groove is formed on the upper surface of the jaw so that the upper surface of the jaw and the eave The cover member with the chin is attached to the base so that the lower surface of the top comes into contact with the back surface of the cover member with the chin and the front end of the eaves does not come into contact. Thereby, a clearance gap is formed between the edge of the eaves and the back surface of the cover member with a jaw.

  The jaw grooves are formed from the proximal end to the distal end of the jaw, and many are formed at regular intervals along the longitudinal direction of the cover member with the jaw. Therefore, a passage is formed through the gap between the edge of the eave and the cover member with the jaw from the chin groove, and further through the gap between the field edge and the eave heaven formed by the ventilator rim, and this passage forms an attic and outside air. And ventilation is performed.

By providing the overhanging portion 31, it is possible to reduce the gap between the eaves 10 and the makeup blast 2 and make it difficult to visually recognize the gap from the lower side of the eaves. A wet sealant or the like is applied to the gap 32 between the eave heaven 10 and the makeup blast 2 to connect the eave heaven 10 and the makeup gust 2. Since the gap 32 is sufficiently reduced by the overhanging portion 31, it is possible to easily apply a wet sealant or the like.

  In the eaves-end ventilation structure according to the present embodiment, as shown by an arrow 90 in FIG. 2, the gap between the plate-like main body 20 and the filter holding portion 21 can function as a ventilation path, and ventilation between the attic and the outside air is possible. Can be performed.

  Next, the dimension of the eave heaven 10 is determined, and the eave heaven 10 is attached to the ventilation trunk edge 8 using the nail 13 and the eave heaven mounting bracket 12. At this time, the dimension of the eaves ceiling is determined so that the front end portion of the eave ceiling 10 is placed on the upper side of the overhanging portion 31 of the makeup windbreak. Since the overhanging portion 31 overhangs below the eave heaven, the gap between the eave heaven 10 and the makeup blast 2 is hardly visible from the outside, and the dimension adjustment of the eave heaven 10 can be facilitated.

  After the eave heaven 10 is attached, the gap 32 between the eave heaven 10 and the makeup gaze 2 is sealed with a sealing material.

  In the eaves vent structure constructed as described above, a ventilation passage 23 for ventilating the attic and the outside air is formed by the makeup blast 2 as shown in FIGS. Moreover, this ventilation path is demarcated by the opposing surfaces of the two members connected by the connecting bracket, and a large space can be rounded. Although this ventilation path is formed in the vertical direction, it has a certain length, and since the ventilation filter 24 is provided inside, it is difficult for rainwater to enter from the outside. 6 has a shape that is difficult to corrode.

A wet sealant or the like is applied to the gap 32 between the eave heaven 10 and the makeup blast 2b to connect the eave heaven 10 and the makeup gust. Since the gap 32 is sufficiently reduced by the overhanging portion 31, it is possible to easily apply a wet sealant or the like.

  In the eaves-end ventilation structure according to the present embodiment, as shown by an arrow 90 in FIG. 11, the gap between the plate-shaped main body 20b and the filter holding portion 21b can function as a ventilation path, and ventilation between the attic and the outside air is possible. Can be performed.

  As described above, according to the eaves vent structure of each embodiment of the present invention, the area defined by the plate-like main body 20 and the filter holding portion 21 can be used as a ventilation path in the decorative blast 2. In addition, since the filter holding portion 21 is provided so as to protrude from the plate-shaped main body 20 toward the eave ceiling 10, the gap with the eave ceiling can be reduced, and the dimension adjustment of the eave ceiling 10 can be facilitated. it can.

  In addition, this invention is not limited to the said embodiment, It can implement in another various aspect.

  Further, the decorative member of the present invention is not limited to the windbreak plate of the above embodiment, and can be used for a nasal cover material.
