Abstract

PURPOSE:To simplify an air ventilating structure to be installed to the frontage of a house by forming the air passage of a ventilating hole of eaves base frame, outside wall surface, and ceiling board and fixing them with an eaves base fitting provided with the ventilating hole communicated with the air passage and a water dripping piece. CONSTITUTION:This air ventilating structure is formed of an outside wall surface 4 from which a frontage member 11 protrudes to the outside and an eaves ceiling board 6 having a gap 20 communicated with an air passage 19 on the side of an adjacent frontage base frame 5. Then the air ventilating structure is fixed to the frontage member 11 with an eaves base section fitting 3 provided with a vertical piece 7 having a ventilating hole 21, outsidefacing piece 9, and water dripping piece 10. The frame 5 is formed of an eaves decorative base member 33, frame member 34, and horizontal frame member 35. Therefore, the frontage member can be formed easily and the air ventilating structure can be simplified. At the same time, the need of a watertight member for dripping water can be eliminated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention enables the easy formation of an eave member having a ventilation hole at the eaves of a house that allows ventilation between the inside and outside of the house, which streamlines work at the site and improves the appearance. This paper relates to a ventilation structure at the eaves of a house that can improve the design.

[Conventional technology]

To form a ventilation hole at the eaves of a house, for example, the 20th,
As shown in Figure 21, the outer wall surface a of a house with a protruding eaves
In order to form an air passage i, an L-shaped member is fixed so that the protruding piece b1 is disposed above, and a plate material d is placed on the upper surface of the protruding piece b1.

Furthermore, a horizontal member f that forms an eave base frame e in the notch of the member
is attached, and then the outer wall side of the eaves soffit material g is fitted to the locking fittings attached to the lower surface of the horizontal member f, thereby attaching the soffit material g to the lower surface of the eave base frame e. , a ventilation hole was formed between the outer wall surface a and the edge of the soffit material g.

[Problem to be solved by the invention]

However, in such a ventilation structure at the eaves, the horizontal member f
Since the air rising through the gap between the outer wall surface a and the outer wall surface a directly hits the plate material d, it is necessary to install a watertight material j at the portion where the plate material d and the outer wall surface a contact.

Furthermore, it is not easy to position the plate material d etc. when attaching it to the outer wall surface a, and together with the need for the watertight material j, the work efficiency is poor. Furthermore, the exterior design looks inferior because the wooden parts are seen through from below.

The present invention improves the efficiency of installation work and the external design by using a cross member that runs along the outer wall surface and fixing an eave base metal fitting having a draining piece whose inner end touches the outer wall surface below the cross member. The object of the present invention is to provide a ventilation structure for the eaves of a house that can solve the above problems.

[Means to solve the problem]

This application covers the outer wall surface of a house from which the eaves of the roof of the house protrude;
an eave base frame having a horizontal member disposed between the outer end of the eaves part and the inner end of the eaves part facing the outer wall surface and along the outer wall surface;
and an eaves member made of an eave ceiling material that is attached to the lower surface of the eaves base frame and forms a gap between it and the outer wall surface that communicates with an air passage that passes through the back surface of the horizontal member and leads into the eaves part,
a vertical piece that rises in the gap and has a ventilation opening communicating with the air passage; an outward-facing piece that extends from the vertical piece and contacts the lower surface of the soffit material; and an inner end that extends inside the vertical piece and contacts the outer wall surface. This is a ventilation structure for the eaves of a house, which is constructed by fixing an eave base metal fitting with a draining piece in contact with the eaves.

[Effect]

As described above, the ventilation structure for the eaves of a house according to the present invention communicates with the air path leading into the eaves through the outer wall surface of the house, the eave base frame having a cross member along the outer wall surface, and the back surface of the cross member. It has an eave member made of a soffit material that forms a gap with the outer wall surface. This facilitates the formation of the eaves member and simplifies the ventilation structure.

Also, a vertical piece that rises in the gap and has a ventilation hole communicating with the air passage, an outward facing piece that extends outward from the vertical piece and contacts the lower surface of the soffit material, and an outward facing piece that extends inward from the vertical piece and contacts the outer wall surface. By fixing the eave base metal fittings that have a water cutter whose inner end touches the wall, the external design is improved, watertight materials, etc. are no longer required, and the formation of the eaves member is facilitated, and ventilation is improved. Structure installation work becomes more efficient.
