Description

[Detailed Description of the Invention] The present invention relates to an auxiliary waterproof sheet for keeping the gap between the lower edge of a roof ridge and a flat tile covered on a sloped roof watertight.

In ancient Japanese-style roof ridges, the door between the ridge tiles and flat tiles was filled with tiles or plaster to prevent rainwater from entering, but in recent Western-style buildings, flat tiles were used. A construction method is often adopted in which Ganfuri tiles and other ridge materials are placed directly on top of the roof.

Therefore, an auxiliary waterproof sheet is inserted into the gap between the ridge building and the flat tiles, but since the flat tiles have height differences and steps in the direction along the ridge, there is a gap between these flat tiles and the auxiliary waterproof sheet. During wind and rain, moisture from the ridge will seep in, shortening the service life of the ridge.

The present invention eliminates the above drawbacks and provides an auxiliary waterproof sheet that prevents water from seeping through the gap between the auxiliary waterproof sheet and the flat tile.

An embodiment of the present invention will be described below 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 a waterproof sheet 2 made of asphalt felt interposed therebetween.

At the center of the upper part of the ridge, a wooden support beam 4 is held and fixed by two right and left 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.

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

An auxiliary waterproof sheet 10 is interposed below the ridge tile 6 to cover the wooden support beam 4, and both hem portions of the sheet 10 surrounding the ridge are formed by the lower edges 6a of the ridge tile 6. flat tile 3
It is interposed so that it is pressed upward.

As shown in the second figure, the auxiliary waterproof sheet 10 according to the present invention is provided with a plurality of parallel slits 11 in the direction perpendicular to the ridges at the hem portion, forming a tear piece portion 12.

The cut piece portions 12 are each independent, and by their own weight act to follow the height of the lower flat tile 3 and close the gap with the flat tile 3.

Furthermore, when rainwater enters this tear piece portion 12, the slit 11 draws water due to the capillary action of the water and creates a series of water curtains, thereby preventing further water from entering in the direction of the ridge.

FIG. 3 shows another embodiment, in which a separate waterproof sheet 10a is laminated and pasted to the hem portion of the auxiliary waterproof sheet 10, this separate waterproof sheet is also provided with slits lla, and the tear piece portion 1
2a is formed.

In this case, the tear piece portion 11. Since the thickness of lla increases, the waterproofing effect is further improved.

Note that if a water-absorbing material such as natural fiber cloth or a water-absorbing and expanding material is used for the hem, the wind and rain blocking effect will be further improved.

As described above, in the present invention, an auxiliary waterproof sheet is attached to the ridge, and the auxiliary waterproof sheet covers the support beam for attaching the ridge accessory, and its hem is inserted into the gap between the lower edge of the ridge accessory and the flat tile. Since the slit is provided in the hem, the auxiliary waterproof sheet conforms to the flat tile without being affected by the height or level difference of the flat tile.
It fits tightly and seals the gap between the roof tile and the flat tile to prevent rainwater from entering.

Furthermore, if rainwater enters partway into the ridge due to strong winds and rain, a water curtain will be formed in the slit due to the capillary action of the water, preventing further water from entering.

In this way, the present invention can provide a waterproofing effect easily and inexpensively even when plaster is not used on the door portion of the ridge.
