Description

[Detailed Description of the Invention] The present invention relates to an improvement of a roof ridge structure, and particularly to a structure for preventing rainwater from entering from the lower edge of a ridge.

For the ridges of conventional Western-style buildings, as shown in the reference diagram, a construction method is adopted in which hard tiles and other ridge materials are placed directly on flat tiles (hereinafter referred to as flat tiles) made of asbestos cement. There are many.

In this case, an auxiliary waterproof sheet 10 is interposed in the gap between the ridge tile 6 and the flat tile 3, but since the flat tile 3 has height differences and steps in the direction along its ridge, Rainwater infiltrates through the gaps between the flat tiles 3 and the ridge tiles 6.

Of these, rainwater that has entered between the flat tile 3 and the auxiliary waterproof sheet 10 is further transmitted onto the flat tile 3 and rises.

In order to prevent this rainwater from entering, caulking material 11 has conventionally been filled in the gap between the bracket 5 and the flat tile 3, but since the caulking area covers the entire length of the ridge, it is necessary to use a large amount of expensive caulking material. This led to an increase in costs and required a lot of construction work.

Additionally, during construction, the adhesion of the caulking material may come off, or after construction, gaps may form due to aging, making it impossible to fulfill its waterproofing role.

As a result, water may enter the ridge part and cause the lower waterproof sheet 2
This had the disadvantage of accelerating the aging of the roof and shortening the useful life of the roof ridge.

The present invention eliminates the above-mentioned drawbacks and provides a ridge structure which can prevent rainwater flowing along the upper surface of a flat tile from reaching the ridge part without applying caulking as described above.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Figures 1 and 2, the roof board 1 in the ridge part
A flat tile 3 is covered on the upper surface of the roof with an underlay waterproof sheet 2 made of asphalt felt interposed therebetween.

A wooden support beam 4 is held and fixed in the upper center of the roofing board portion by a pair of opposing support metal fittings 5.

The leg portion 5a of the receiving metal fitting 5 is inserted and supported between the flat tile 3 and the waterproof sheet 2, and is fixed to the roof board 1 with nails 15.

A ridge tile 6 is placed on the top of the ridge portion, and is fixed to the wooden support beam 4 with nails 9 through a washer 7 and a seal 8 from the upper surface side.

An auxiliary waterproof sheet 10 is installed below the ridge tile 6 to cover the wooden support beam 4 and run along the ridge.
Both edges of 0 hang down over the upper end of the flat tile 3, and the hem 1
0a is held by the seat fixtures 12.

The seat fixing device 12 is made of a metal plate, a plastic plate, etc. as shown in the second figure, and has a main body 1 of a long strip along the ridge.
The auxiliary waterproof sheet 10 is held in a watertight manner by the bent piece 2a and the bent piece 12b whose one edge in the width direction is bent by 180 degrees.

A nail hole 12c is provided in the main body 12a. The fixing tool 12 is installed in a direction in which the hole 12c is covered by the auxiliary waterproof sheet 10, that is, in an upwardly opening state, and is fixed to the upper end of the flat tile 3 by driving a nail 16 into the hole 12c.

In addition, in the figure, 13 indicates a ridgepole, and 14 indicates a rafter.

In the above structure, wind and rain blowing in through the gap between the lower edge 6a of the roof tile 6 and the flat tile 3 collides with the fixture 12, is decelerated, and is blown onto the inclined upper surface of the auxiliary waterproof sheet 10.

Therefore, rainwater does not infiltrate the back surface of the auxiliary waterproof sheet 10, and of course does not reach the ridge portion of the palm-shaped roof board.

The rainwater accumulated on the front side of the auxiliary waterproof sheet 10 flows down again from the gap between the ridge tile 6 and the flat tile 3 along the roof slope.

In addition to the above-mentioned clamping method, there are other methods of joining the fixing device 12 and the auxiliary waterproof sheet 10, such as using an adhesive, or using a combination of rivets and adhesive tape, but in any method, it is important that no gap is formed between the two. is necessary.

As described above, in the present invention, an auxiliary waterproof sheet is attached to cover the support beam for attaching roof tiles, and the hem of the auxiliary waterproof sheet is
On the lower side thereof, the eave side edge of the long strip is bent diagonally upward to the ridge side along the ridge extending on the upper surface of the flat tile, and is held in a watertight manner by a fixture, and the fixture is the auxiliary waterproofing member. The part covered by the sheet was sealed and fixed to the top edge of the flat tile, and the roof tile was attached to cover it, so rainwater would not enter the ridge during wind and rain, making construction easier. It is easy to install, has improved waterproof performance, and extends the useful life of the ridge.

Additionally, since no caulking material is required, it also helps reduce costs.
