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, the rainwater that has entered between the flat tile 3 and the auxiliary waterproof sheet 10 further flows over 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. However, 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 capable of preventing rainwater flowing along the upper surface of a flat tile from reaching the ridge part without applying caulking as described above.

An embodiment of the present invention will be described below with reference to 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 at 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, and is attached to the wooden support 4 by nails 9 through a washer 7 and a seal 8 from the upper surface.
Fixed.

An auxiliary waterproof sheet 10 is installed below the ridge tile 6 to cover the wooden support beam 4 and run along the ridge, and both edges of the sheet 10 hang over the upper end of the flat tile 3. An adhesive layer 12 is formed on the back surface of the hem portion 10a.

As shown in the second figure, the adhesive layer 12 has adhesive portions 12a which are diamond-shaped in plan view and are formed into grooves 12 in a staggered manner to prevent intruding rainwater from going straight.
It is placed with b in between.

The thickness of the adhesive part 12a is approximately 21rrIn1 each adhesive part 12a
The width S of the groove 12b formed therebetween is approximately 10771171 mm.

This auxiliary waterproof sheet 10 is adhesively fixed to the upper surface of the flat tile 3 by the adhesive portion 12a.

A release paper is pasted on the adhesive layer 12 in advance, and the adhesive layer 12 can be attached by peeling off the release paper during use.

In addition, in the figure, 13 is a ridgepole, and 14 is a rafter. During construction, the auxiliary waterproof sheet 10 is placed with the adhesive layer type side facing downward, so as to cover the support beams 4 evenly on the left and right sides in the width direction, and the release paper is removed from the part that falls on the flat tiles 3. In addition, it can be easily attached and fixed by pressing it against the flat tile 3.

In the above structure, the wind and rain blowing through the gap between the lower edge 6a of the ridge tile 6 and the flat tile 3 is slowed down inside the ridge tile 6, and most of it is transferred to the upper surface of the auxiliary waterproof sheet 10. It blows up along the way.

Even if some rainwater enters the grooves 12b of the adhesive layer 12, it is further slowed down by the staggered arrangement of the adhesive parts 12a.
Rainwater does not reach the ridges of the palm-shaped roof boards.

Even if water enters the groove 12b due to capillary action, it becomes water droplets and is conversely discharged down the groove 12b along the roof slope.

On the other hand, regardless of whether it is rain or shine, air passes through the ridge 112b and flows into the ridge, so this area can always be kept dry.

As described above, in the present invention, an auxiliary waterproof sheet is attached to cover the support beam for installing ridge tiles, and the auxiliary waterproof sheet has grooves on the back side of the hem that prevent infiltrating rainwater from going straight and allow water to flow down. An adhesive layer is formed and is fixed to the upper end of the flat tile by the adhesive layer, and the roof tile is attached to cover these, so rainwater does not enter the ridge during wind and rain. This combined with the ease of construction, improved waterproof performance, and constant dryness due to the inflow of air, significantly extended the useful life of the ridge.

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