Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ridge ventilation system installed on a ridge such as a gable roof to exchange indoor and outdoor air.

Conventional technology Conventionally, in this type of ridge ventilation system, the top plate side and the base side are assembled integrally with each other separated by a ventilation interval that allows indoor and outdoor air to flow. In order to prevent rainwater that enters from the mouth with the outside air from moving indoors, a baffle board that is bent into a complex structure to block rainwater is installed within the space between the top plate and the base. It is usually composed of:

Since the ridge ventilation system has a complicated structure of baffle plates assembled inside, there are drawbacks such as the rise of the ridge on the ridge becomes large, spoiling the overall appearance of the house, and being easily agitated by wind and rain.

Problems to be Solved by the Invention The present invention provides a ridge ventilation system that has a simple structure, is thin, and is configured to reliably block rainwater that enters with outside air from moving to the ridgepole gap in the ridge. The purpose is to

Means for Solving the Problems The ridge ventilation system according to the present invention includes a top plate section whose cross section is approximately umbrella-shaped from the left and right slope plates bent at a predetermined angle at a central location corresponding to the ridge section; It consists of left and right base parts having bottom plates fixed to each roof surface on both sides of the ridge part with ventilation intervals between them and each slope plate of the top plate part, and the top plate part and each base part are the same as described above. A rising plate is bent upward from each upper edge of the bottom plate to set the ventilation interval, and each slope plate of the top plate is fixed by being bent downward from each upper edge of the rising plate toward the roof slope. The top plate is a flat plate that is bent downward from the bottom edge of each slope plate to form an external ventilation gap between the tip edge and the surface of the bottom plate. each base part has a flat baffle plate bent downward from the bottom edge of the stop plate to form an internal ventilation gap between the tip edge and the bottom plate; A flat baffle plate that is bent upward from the bottom plate at an intermediate position between the plate and the full-face blocking plate to form an internal ventilation gap between the tip side and the plate surface of the slope plate; A ventilation hole is formed on the board surface and communicates the ventilation interval with the ridgepole gap of the ridge part, and the airflow hole is provided to prevent air flowing in and out from the ventilation gap of the front shielding plate and the ventilation hole of the upright board. It is constructed by providing airflow intervals in a meandering manner using plates.

Function In this ridge ventilation system, a flat front shielding plate is bent and formed from each slope plate of the top plate, and an external air gap is created between the tip of the front shielding plate and the bottom plate of the base. By providing a ventilation gap, not only can rainwater that enters the ventilation space with outdoor air be reduced, but also
In addition to providing a front shielding plate on the top plate, a stop plate on the base and baffle plates placed alternately above and below the bottom plate are also provided on the base to integrate the top plate and the base. It can be assembled into a simple and thin structure, and since the air flowing in and out of the ventilation interval is meandered through each baffle plate, even if rainwater enters with outdoor air, it will not leak indoors. This makes it possible to effectively shut off the air in the middle of the ventilation interval to prevent it from moving up to the point where it occurs.

When there is rainwater moving inward from g ₃ and g ₄ , the baffle plates 26, 36, 27, and 37 alternately protrude from above and below at regular intervals, causing the air to meander within the ventilation interval G. Since the water is allowed to flow, the baffle plates 27, 37, 26, 26, and 36 can reliably drain the water, thereby preventing it from entering the room.

Effects of the invention As described above, according to the ridge ventilation system according to the present invention, a front shielding plate is provided on the top plate side, and baffle plates positioned alternately above and below are provided on the base side. Since the slope plate on the top plate and the stop plate on the base are fixed together, it not only has an extremely simple structure, but also allows almost all rainwater to be absorbed by the slope plate on the top plate and the front shielding plate. It can be completely shut off, and even if rainwater enters within the ventilation interval, it can be reliably drained by the upper and lower alternating baffle plates, thereby preventing it from moving indoors.
