Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a device for ventilating an attic space, which is suitable for roofs of houses, particularly roofs made of metal sheets.

[Conventional technology]

Roofs of ordinary houses, especially roofs made of metal sheets, can become quite hot in the attic during summer and rainy seasons, making it uncomfortable to live in and damaging the durability of the frame and roofing materials. The current situation is that it is not being done.

[Problem that the invention seeks to solve]

The present invention provides a ventilation system that can ventilate the attic of a general house and can be easily installed.

[Means for solving problems]

In the ventilation system of the present invention, the roofing board and the roof board are assembled with a gap or opening formed in the ridge part, and the pre-assembled main body is located above the opening and between the roof boards on both sides centering on the ridge. By being installed to bridge the
The attic is ventilated through the opening, and the roof shingles are housed in the ridge.

The body itself includes an elongate central member extending along the ridge, a ridge wrapping member, and a frame member spaced apart from each other along the ridge and connecting the members. There are a pair of central members. Each central member has a substantially L-shaped cross section and is arranged such that the side walls forming one side of the L shape face each other and are spaced apart from each other. The ridge wrap member has a generally channel-shaped cross section having a pair of opposing side walls and a top wall connecting the side walls and is positioned over the side walls of the central member. The arrangement is such that the pair of side walls face the side walls of the central member and form a gap, and the top wall covers the central member so as to form a gap with the ends of the side walls of the central member. Together with the gaps between the side walls, they form one ventilation path. The end face member is fitted and fixed to both ends of the ridge wrapping member,
The open ends of the central member and ridge wrapper member are closed. The frame member is positioned within the air passage formed by the center member and the ridge wrap and has a profile capable of contacting the inner surfaces of the center member and the ridge wrap. The frame members are spaced apart along the length of the central member and the ridge wrapper, or in other words, between the end members, and are connected to the central member and the ridge wrapper. The relative positional relationship between the central member and the ridge wrapping member is fixed by these frame members.

An insect-proof net is disposed at the end of the ventilation path on the outside space side, between the side walls of the central member and the ridge wrapping member,
It covers the opening on the outside space side of the ventilation path. Furthermore, a pair of splash stoppers made of perforated plates are positioned inside the insect-proof net in the ventilation passage and between the side walls of the central member and the ridge wrapping member, and are spaced apart from each other.

The wall forming the other side of the central member and the associated portion of the frame member are preformed in a shape that follows the member to which the body is attached to the roof shingle. This main body is constructed by a frame member bridging the roof panels, and a part of the ventilation path between the side walls of the central member being placed on the roof so as to pass through the opening on the ridge formed by the roof panels and the roofing board. , can form a roof ridge or part of it. The attic space is connected to the outside space through openings formed by the roof sheets and sheathing boards and ventilation paths inside the main body, and heat and moisture in the attic space can be exhausted to the outside space through these openings and ventilation paths. , can reduce the temperature and humidity in the attic space. Insect netting also prevents insects from entering the attic. Furthermore, since the opening on the outside space side of the ventilation channel faces the roof board, rainwater cannot enter the ventilation channel. Even if rainwater enters the ventilation channel through an insect repellent net, it cannot be prevented from reaching the attic by using spray stoppers. can.

In the ventilation system of the present invention, depending on the installation environment, each of the side walls located inside the perforated plate and facing each other of the central member and the ridge wrapping member is provided with a wall i- facing the other side wall. Baffles may be provided that extend from the roof to form a labyrinth in the air passageway to prevent rain spray from entering the attic space during rainstorms or the like. Moreover, a duct can be provided in the end face member as necessary, thereby allowing ventilation to be carried out from the end face of the main body as well. It is desirable that the opening on the free end side of the duct faces the roof board, or in other words, faces downward. This can be done, for example, by the duct itself being L-shaped. Insect nets and baffles are built into the ducts to prevent insects and rainwater from entering the attic space.

Embodiments of the ridge ventilation system of the present invention will be described below with reference to the accompanying drawings.

〔Example〕

In FIG. 1, lO indicates the main body of this ridge ventilation system. This main body is installed on the ridge of the roof and forms part of the ridge or the entire ridge.

As clearly shown in Figure 2, the roof is laid out in such a way that the sheathing board 12 on the haze 11, the undercoat 13, and the roof board 14 form a gap 15 at the ridge of the roof. By that,
An opening corresponding to the main body 10 is formed in the ridge. The main body 10 is assembled in advance as one unit, fixed to the roof so as to cover the opening in the ridge, and communicates the attic space with the outside space through a ventilation passage formed inside.

The main body itself includes a central member, a ridge wrapping member, and a frame member 40, as shown in FIGS. 2 and 3.

The central member consists of a pair of members having an L-shaped cross section and extending over the entire length of the main body. Each member is arranged in parallel with the side walls 21 facing each other and forming a gap n connecting to the gap 15. L
The base wall forming the other side of the letter is formed in a form corresponding to a member for installing the main body on the roof, as will be described later.

The ridge wrapping member I has approximately the same length as the central member.

The ridge wrapper itself has a hollow channel-shaped cross section consisting of a pair of opposing side walls 31 and a top wall 32 connecting the sides. This ridge wrapping member is placed over the side wall 21 of the central member so that the side wall 31 faces the side wall 21 and forms a gap, and the top wall 32 is placed between the upper edge of the side wall 21 and the upper edge of the side wall 21. They are arranged so as to form a gap tone of approximately the same size as the gap. These gaps 22, 33.3 are provided between the central member and the ridge wrapping member.
4 forms one ventilation path.

The frame member 40 fixes the relative positional relationship between the central member and the ridge wrapping member, and allows the main body to be installed on the roof. The frame members are narrow in width and are arranged at regular intervals along the longitudinal direction of these members inside the ventilation passage formed by the central member and the ridge wrapping member. The frame member itself has a profile that contacts the inner surfaces of the center member and the ridge wrapping member. In this case, the frame member is the lower base piece 41
It has an upright piece 42 erected at the top, and an upper piece 43 located at the upper end of the upright piece, and the upright piece is in close contact with the side wall 21 of the central member, and the upper piece 43 also forms a space between the ridge wrapping members. It is formed in a shape that closely fits the top wall 33 and side walls 31 and 32. Both ends 44 of the upper piece are bent so as to cross the ends of the ventilation passages and are brought into close contact with the upright piece. The frame members are interconnected and integrated by members 46 and 47 located at the base of the upright piece 42 and by a member 48 located at the top piece 43.

The main body also incorporates insect netting and splash protection. The insect-proof net is held between square frames 51 and has a length that is related to the overall length of the main body or the spacing between the frame members. The net is arranged to bridge the end members of the top piece of each frame member, and
It is screwed to 4. Although not shown, a holding member having the same width as the frame member is arranged to sandwich the net together with the end member, and the net is screwed together with the holding member to the end portion 44. The ventilation path is covered with an opening on the outside space side by this insect-proof net.

The splash stop is constituted by a member 60 placed inside the insect screen in the air passage. This member is made of a plate having a large number of small holes, such as punched metal, and has a length approximately equal to the entire length of the main body, which is approximately U-shaped in cross section. The splash stopper is arranged along the longitudinal direction of the central member and the ridge wrapping member so that the two overlapping portions bridge the side walls n and 31 of the central member and the ridge wrapping member. Fixation is done by fixing the part parallel to the side wall 21 of the central member to the side wall 21 of the central member with screws.
This is done by combining 1. This ridge ventilation system incorporates a second set of splash stops. It consists of two baffle plates 61 and 62 located inside the perforated plate 60 and placed in the ventilation path. The baffle plate 61 itself is an elongated piece having a substantially double-shaped cross section and extending over the entire length of the main body, and is bolted to the top piece of each frame member.

On the other hand, the baffle plate 62 is formed as a part of the side wall 21 of the central member. Each baffle plate is inclined diagonally downward toward the opening on the side of the external space in the ventilation passage, and has an end portion bent approximately vertically. Each baffle plate has a gap formed between its end and the side walls 21 and 31, forming a labyrinth within the ventilation path.

End members close both ends of the body. Each end member has two portions 71.7, as best shown in FIG.
It consists of 2. The end face member 71 covers the upper half of the end face, and has a box shape with one end open. The peripheral wall 71 is bent in a shape that follows the side wall 31 and top wall 32 on the ridge wrapping member side, but the side wall 71 on the central member side
1 and the border between the base wall and the base wall. The end wall 74 is disposed to cover one end of the peripheral wall and is formed integrally with the peripheral wall. Attachment is accomplished by fitting the peripheral wall 73 to the outside of the ridge wrapping member I and fixing it with rivets or the like. Another end member 72 is fitted inside the frame member 40 and secured thereto. For this purpose, the end member 72 is provided with a circumferential wall 75 bent into a shape that follows the lower surface of the base piece 41 of the frame member. An end wall 76 is located at one end of the circumferential wall so as to cover the end surface of the body when the circumferential walls are mated together. An extension wall 76 that overlaps other members is formed at the lower edge of the end wall 75 at right angles to the end wall.

The main body is installed on the roof so as to cover the gap or opening formed in the ridge. Figure 4 shows the details IIt8
It shows. As described above, the roof board 14 is raised together with the roof board so as to form an opening 081 corresponding to the main body 10. The drain plate 82 is bent into a chevron shape at an angle related to the pitch of the roof and has a drain formed at each edge. These draining plates are placed on the ridge so that a part thereof is located above the opening 81. The mounting base 83 is made of wood, and is placed along the longitudinal direction of the opening 81 on the roof draining board and the roof 11 so as to form a gap between them, and is attached to the roof 11 with nails. Fixed. Main body 1
0 is placed on these mounts 83. For this purpose, the center member of the main body 10, the base wall of the frame member 40, and the base piece 41 are formed in a shape that follows the shape of the mounting base 83, and the base wall n is extended so as to be in contact with the roof plate 14. A drain is provided on the edge. The main body is fixed using the base wall of the central member and the base piece 4 of the frame member ■.
1 to the mounting base 83 with nails. Then, the wire plate 85 is placed and fixed on the ridge so as to cover the extension wall 76 of the end face member 72.

The installed main body can communicate between the attic space and the outside space through the ventilation passage.

For this reason, the air in the attic space is trapped between gaps 15 and 22.
.

The air in the outside space flows into the attic space through the ventilation path formed by A and 34, and the heat and moisture in the attic are exhausted to the outside by these air exchanges. At this time, since the device itself is placed on the ridge of the roof, ventilation can be made effective.

Insects and rain are prevented from entering because the opening on the outside space side of the ventilation path faces downward, and furthermore, insects are prevented from entering the attic space by the insect-proof net 50. Rain enters the ventilation passage through the insect-proof net, but since it is blocked by the splash stopper or perforated plate 60, further intrusion can be prevented. Furthermore, even if rain enters through the perforated plate marks during a rainstorm, the wind hits these baffles as it passes through the maze of baffle plates 61 and 62, preventing the rain from penetrating deeper into the ventilation passage. can do. Since the baffle plate is tilted downward, the rainwater that has adhered to the baffle plate will flow down the baffle plate.

In this device, the top wall 32 of the ridge wrapping member is connected to the roof plate 14.
It is formed by multiple slopes that slope toward
Not only does it allow rainwater to flow well over the outer surface, but
Rain that has entered the ventilation path is made to flow outward along the inner surface of the top wall 32. In other words, in the event of a storm, etc.
The wind passes through the maze formed by the baffle plates 61 and 62 and reaches the top wall 32, or at this time, rainwater contained in the wind passes through the baffle plates 61 and 62 and is attached to the top wall 32, but the top wall itself The slope prevents the water from flowing down along the slope and entering the attic space through the ventilation channels.

In this ventilation system, the main body 10 can be provided at both ends with means for connecting the attic space and the outside space. Figures 5 and 6 illustrate such means. It consists of an L-shaped duct 90 attached to the end member 74.

This duct is shaped like a square pipe and is attached to an opening in the end wall 74. Attachment is accomplished by applying seven flanges 91 around one open end of the duct to the inner surface of the end wall and connecting them with screws. An insect net 92 is disposed at the other opening in this duct. The insect-proof net itself consists of a pair of frame members sandwiching and bonding the net together, and is placed on the inner surface of a horizontal wall that forms the opening of the duct, and is positioned using retainers 93 and 94, and is secured with screws. Fixed by Presser foot 9
The wall on the side of the end wall 91 at No. 3 is extended vertically, and its tip is bent diagonally downward toward the opening of the duct.

This curved section forms an exclusion or splash stop for rainwater entering through the net 92.
Ru.

The ventilation path formed between the central member and the ridge wrapping member will be connected to the external space by these ducts 90 at both ends. Insects are prevented from entering the inside of the duct and the ventilation passage by the net 92, and rainwater that enters through the net 92 is directly blocked by the two downwardly sloping walls and the retainer wall 94 that make up the earthen wall of the duct. It is prevented from entering the air passages, and any deposits are allowed to flow down these walls.

〔Effect of the invention〕

As described above, the ridge ventilation system of the present invention has gaps or openings formed in the roof panels and roof panels at the ridge, and a main body having a ventilation path connecting this gap to the outside space bridges the roof panels. Since it is installed in this manner, the attic space can be effectively ventilated and the roof can be closed off. Furthermore, since the main body is pre-assembled, it can be installed simply by placing it on the roof and fixing it, making construction extremely easy.
