Description

[Detailed description of the invention] Industrial field of application The present invention relates to a ventilation system installed at the top of a square roof of a general house.

PRIOR ART Conventionally, there are various types of ventilation devices that are installed on the roofs of ordinary houses, such as halfway up the slope of the roof. It cannot be handed over and installed.

Problems that the invention aims to solve: However, for square roofs, it would be desirable to install a ventilation system that uses the apex of the roof as the ventilation point, and it is also desirable to install a ventilation system that reliably prevents rainwater from entering the building during ventilation. It is better to do so.

Means for solving the problems In the square roof ventilation system according to the present invention,
The outer frame and the inner frame of each similar shape are approximately quadrilateral and fixed at regular intervals by a connecting plate that is installed by hanging between each corner part, and a plurality of frames are made to protrude horizontally from each opposing surface alternately. The baffle plates are arranged within opposing intervals, and furthermore, a top plate is provided by fixing them to the upper end side of the outer frame, and installation plates located below the lower edge side of the outer frame are installed from each lower end side of the inner frame. It is constructed by bending outward.

Function: With this ventilation system, the installation plates bent outward from each lower end of the inner frame can be fixed by spanning each slope at the apex of the square roof, and each installation plate can be adjusted to correspond to the roof slope. Furthermore, even if rainwater enters from the lower end of the outer frame with the outside air flowing inside the inner frame, the baffle plate can effectively block the rainwater, making it ideal for indoor use. There is no possibility of intrusion.

Embodiments The following description will be made with reference to the accompanying drawings.

This ventilation system is installed at the apex of a square roof so as to span each slope, and each component is assembled by cutting and bending sheet metal into a predetermined shape. Its components include an approximately square outer frame 1, an inner frame 2 of similar shape and a relatively small frame, and a square pyramid-shaped top plate 3 fixed to the upper end of the outer frame 1. It is assembled.

The outer frame 1 is assembled with four frame plates 10, 11, and 12, as shown in FIG. 2 with some parts omitted, and each frame plate is assembled with left and right connecting plates 10a, 1 as shown in FIG.
0b, a bottom frame plate 10c, and a baffle plate 10d to be assembled as described later, and are cut into shapes. Further, this frame plate 10 includes left and right connecting plates 10a,
10b is bent inward at a 45 degree angle, the bottom frame plate 10c is also bent inward at a moderate angle, and the baffle plate 10d is bent by 1
It is bent into a predetermined shape by turning it inward at 0e and protruding horizontally. Like the outer frame 1, the inner frame 2 is formed of four frame plates 20, 21, and 22, as shown with some parts omitted in FIG. As shown in FIG. 4, each of the frame plates 20, 21, 22 is molded integrally with the installation plate 4, and the installation plate 4 is bent outward to be placed upright. As shown in Fig. 5, the top plate 3 is cut into a shape from a single sheet, and the inner bending allowances 3a and 3b are formed.
It is bent and molded into each conical shape. In addition to these components, four baffle plate materials 5 as shown in FIG. There is.

To assemble these, frame plates 10, 1
By making the connecting plates 10a and 10b of 1 and 12 face each other and connecting their ends to the frame plates 20, 21 and 22 of the inner frame 2, the inner and outer side frames 1 and 12 are separated by a regular interval.
2 is framed, and the baffle plates 10d of the outer frame plates 10, 11, 12 are positioned in the middle to form baffle plates 5a, 5.
Baffle plate materials 5 are attached to the side surfaces of the frame plates 20, 21, 22 of the inner frame 2 facing the outer frame 1 so as to alternate with the outer frame 1. The top plate 3 is fitted and fixed to the upper edge of the outer frame 1, and the installation plate 4 is located below the lower edge of the outer frame 1 and is separated from the frame plates 20, 21, 22 of the inner frame 2. It is bent outward.

The ventilation system configured in this way has frame plates 20, 2.
Since the installation plates 4 from 1 and 22 are individually bent and formed, they are attached to the roof base plate according to the roof slope, and the left and right ends are bent to match the ridgeline to secure the nails. It can be fixedly installed at the apex of the roof. In addition, in this ventilation system, outside air flows inward from the gap between the bottom frame plate 10c and the inner frame 2 and passes through the baffle plates 5b, 10d, and 5a to the top plate 3.
It enters the room through the purlin spacing (not shown) by flowing within the frame of the inner frame 2 towards the room. Even if rainwater enters with the outside air, the outside air can be removed from the baffle plate 5.
Since the water flows in a meandering manner through channels 5b, 10d, and 5a, it is drained by baffle plates 5b, 10d, and 5a on the way, so that it does not enter indoors.

Effects of the invention As described above, according to the square roof ventilation system according to the invention, not only can it be installed at the apex point according to the slope of the roof, but also it is possible to reliably drain rainwater so that it does not enter indoors. It is meant to be.
