Description

[Detailed explanation of the invention] Various natural ventilation systems installed at the ridges of building roofs have been proposed, but this invention is particularly useful for improving the efficiency of on-site work and improving the efficiency of joints. The present invention aims to provide a device that is highly effective in preventing rain leakage, and its structure, operation, and effects will be clarified with the following explanation of embodiments shown in the drawings.

In the figure, 1 is a ridgepole, 2 is a rafter, 3 is a roof board, 4 is a roofing, 5 is a roofing material, 6 is a ridge supporting material, and 7 is a cap, which are arranged symmetrically on both sides of the ridgepole 1. A ventilation passage 9 extending upward is formed in the center of the roof 8 of the building.

In this invention, the ventilation roof section 10 configured above the ventilation passage 9 of the building roof 8 has an external material 11 and an internal material 12.
The inner material 12 is made of a flexible material such as soft rubber, soft plastic, waterproof paper, metal foil, and a laminated material or a combination of these materials, and has an approximately inverted U-shape as shown in the figure. A reinforcing body 13 is used to maintain the shape.

This reinforcing body 13 is extended along the inside of the cap 7 and the ridge support material 6, and is inserted between the ridge support material 6 and the roof board 3 to constitute a water return material.

In the figure, the top of the reinforcement body 13 has recesses 1 on both sides.
4, and a vent hole 15 is provided in this portion, and a vent hole 16 is also provided in a corresponding portion of the internal member 12.

In the illustrated embodiment, the external member 11 is a chevron-shaped top plate portion 1.
7, and side plate portions 18 that hang down from both sides of this top plate portion 17.
19, and a hem portion 2 that continues below these side plate portions 18 and 19.
0, 21, and these hem portions 20, 21
is extended along the cap 7 of the building roof 8 and fixed to the cap 7 with a suitable fastening piece (for example, a nail) 22, but at this time, there is no space between the cap 7 and the hem 20, 21. The lower edges of the inner members 12 are sandwiched and fixed together, thereby providing an effect of preventing rain leakage at the seams.

Note that an exhaust port 23 is provided in the side plate portion 18.19 of the external member 11.
．． 24 are provided, and these side plate parts 18, 19 and a hem part 20
A drain port 27.28 is provided in the bottom plate portion 25.26 formed at the intermediate portion between the bottom plate portion 21 and the bottom plate portion 25.26.

In fact, the internal material 12 can be rolled up into a long length and cut as appropriate at the construction site for use.In this respect, it greatly contributes to improving work efficiency, and furthermore, the internal material 12 It is extremely advantageous in practical terms because it serves as a backing for the attachment section.

In the device having the above structure, ventilation within the building roof 8 is carried out from the ventilation path 9 through the vents 15.16 and the exhaust ports 23.24, and the external material 11 is ventilated along with crosswinds, etc.
Rainwater that has entered the space between the interior material 12 and
It is discharged to the outside from 7.28.

The device of this invention is not necessarily limited to a long device installed over the entire length of the roof, but can be installed in a spot-like configuration at any desired location on the roof.

In this invention, the inner material has a two-layer structure, the outer layer is made of a flexible material, and a reinforcing body is provided on the inner side, thereby achieving the following functions and effects.

That is, (1) the layer made of flexible material can be freely changed in shape and dimensions on site to match the form of the ridge ventilation section, and is easy to construct on site.

(2) Since the reinforcing body does not necessarily need to be constructed as a rigid body, it is sufficient to construct it as a frame, which helps to reduce the required weight of the roof ventilation section and also leads to a reduction in material costs.

Claims (1)

[Scope of utility model registration request] 1. A ventilation roof part configured above the ventilation path of a building roof is composed of an external material and an internal material, and an internal material provided with a ventilation hole is arranged inside the external material and is provided with an appropriate exhaust port and a drainage port. It is made of a flexible material and has a substantially inverted U-shape, and a reinforcing body is provided inside this inner member to maintain the inverted U-shaped form so that the inner member maintains its regular shape. A natural ventilation system for a roof, in which the reinforcing body, which has a vent communicating with the vent, is sandwiched between the shedding board and the roofing to form a water return material. 2. Natural ventilation of a roof according to claim 1, wherein the flexible material constituting the internal material is soft rubber, soft plastic, waterproof paper, metal foil, or a laminate or combination thereof.
