Description

[Detailed Description of the Invention] The present invention relates to a roof top ventilation system mounting structure.

The purpose is to provide a structure for mounting a ventilation device on the top of a roof that allows a large amount of air ventilation, is easy to install, and has good stability.

The present invention will be explained below based on embodiments shown in the drawings.

Ventilation holes 2 are formed by cutting out the chevron-shaped top of the roof board 1. The ventilation holes 2 are formed continuously or discontinuously along the top. Drainage plates 8 are installed on the roof plate 1 on both sides of the ventilation hole 2.
are arranged respectively. The ends of the draining plates 8 that are close to the ventilation holes 2 are raised to approximately the same height as the columnar bodies 3, and the upper ends of the raised ends are bent toward the bottom of the roof so that water parallel to the roof surface is raised. A cut piece 8a is formed to prevent rainwater etc. from entering the ventilation hole 2. A plurality of short and small columnar bodies 3 are arranged and fixed in rows at intervals on the draining plates 8 disposed on both side edges of the ventilation hole 2. Further, a rod-like body 4 is placed and fixed on the columnar body 3 so as to connect the columnar bodies 3 arranged in a series. The interval between each columnar body 3 is preferably about 50 to 60 cm. Further, the rod-shaped body 4 is provided so that its upper surface is continuous, and the material thereof may be wood, resin, metal, or the like. Therefore, a vent hole 12 having a size of 50 to 60 cm is formed between each columnar body.

In the figure, 6 is a ridge haze, 7 is a roof board, and 9 is a fixing tool such as a nail for fixing the columnar body 3 and the rod-shaped body 4 to the roof board 1 or the like.

Separately, a ridge decoration plate 5 having a substantially chevron-shaped cross section with both ends bent downward is formed. The ridge decoration plate body 5 is disposed astride the ventilation hole 2 so as to cover it. Portions 5a, 5a bent downward at both ends of the ridge decoration plate 5 and the lower surface of the ridge decoration plate 5 are fixed in contact with the upper and lower surfaces of the rod-shaped body 4. A ventilation gap 11 is formed between the lower ends of the bent portions 5a, 5a of the ridge decoration board 5 fixed in this manner and the upper surface of the roof. Numeral 10 is a nail for fixing the ridge decoration board 5.

As described above, in the present invention, a ventilation hole is formed at the top of the roof by cutting out a roof plate, draining plates are arranged on the roof plates on both sides of the ventilation hole, and the ventilation hole in the draining plate is provided. The opposite ends are raised to approximately the same height as the columnar body, and the upper ends of the raised ends are bent toward the bottom of the roof to form water cut-back pieces parallel to the roof surface, and the ventilation holes are A plurality of short and small columnar bodies are arranged and fixed in rows at intervals on the drainage plates arranged on both side edges, and in this way, on the columnar bodies arranged in parallel on both side edges of the ventilation hole. A rod-shaped body is placed and fixed, and in addition to this, a ridge plate with a substantially chevron-shaped cross section with both ends bent downward is formed, and the ridge plate has the ventilation hole at the top of the roof. The inner surface of the downwardly bent portion of the lower surface and both ends of the ridge decoration board is brought into contact with and fixed to the rod-shaped body, and the lower end of the bent portion and the upper surface of the roof are fixed. Since it has a ventilation gap formed between the parts, it has a simple structure and is easy to install, yet it has excellent strength and durability. Since the installation work is carried out in a dangerous place at the top of the roof where the footing is extremely poor, creating a structure that is easy to install in this way is extremely effective in preventing danger and ensuring the safety of workers. In addition, since ventilation can be carried out through the gap provided between the ridge decoration board and the upper surface of the roof, a large amount of ventilation can be obtained and ventilation efficiency can be increased. In this way, even though the ventilation efficiency is high, rain can be reliably shut off using the draining board. Therefore, it has the effect of preventing dew condensation and greatly increasing the durability of the building.

The ends of the draining plates near the ventilation holes are raised to approximately the same height as the columnar bodies, and the upper ends are bent toward the bottom of the roof to form draining pieces parallel to the roof surface. As a result, rainwater blown in through the gap provided between the ridge decoration board and the top surface of the roof is reliably blocked by the water cutoff piece and does not enter the ventilation holes.

In other words, rainwater can be completely drained out using the drainage plate formed at the same height as the ventilation hole formed by the columnar body, and the rainwater that flows up to the drainage plate can also be completely shut out by the drainage piece. can be prevented. Furthermore, since the downwardly bent portions at both ends of the ridge decoration plate are brought into contact and fixed so as to wrap around the rod-shaped body, the attachment of the ridge decoration plate becomes strong.

Claims (1)

[Scope of utility model registration request] A ventilation hole is formed at the top of the roof by cutting out a roof plate, and draining plates are arranged on the roof plates on both sides of the ventilation hole, and the ends of the draining plate closer to the ventilation hole are arranged in a columnar shape as described below. The above-mentioned pipe is raised to approximately the same height as the body, and the upper end of the raised part is bent toward the bottom of the roof to form a water cut-back piece parallel to the roof surface, and which is disposed on both sides of the ventilation hole. A plurality of short and small columnar bodies are arranged and fixed in a row at intervals on the drainage plate, and one rod-shaped body is placed on each of the columnar bodies arranged in parallel on both sides of the ventilation hole. A ridge decoration plate body having a substantially chevron-shaped cross section with both ends bent downward is formed separately from this, and the ridge decoration plate body is arranged to straddle the ventilation hole at the top of the roof, and The inner surface of the downwardly bent portion of the lower surface and both ends of the ridge plate is brought into contact with and fixed to the rod-shaped body, and a ventilation gap is provided between the lower end of the bent portion and the upper surface of the roof. A roof top ventilation system mounting structure characterized by forming a roof top part.
