JPS5942422Y2 - Drainage structure at the eaves - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roof drainage structure, and particularly relates to an improvement of a roof drainage structure when two buildings having roofs of different heights are connected.

Two buildings with different roof heights are combined, and the roof of the lower building (hereinafter referred to as a single-story building) is joined to the gable side wall of the higher building (hereinafter referred to as a shed), and the roof of the lower building (hereinafter referred to as a single-story building) is If the eaves are located halfway on the gable side wall surface, rainwater will permeate into the walls along the draining plates of the eaves, seep into the walls of the shed, and enter the room.

This phenomenon could not be prevented even with waterproofing agents, and was a major drawback for buildings.

The present invention eliminates the above-mentioned drawbacks and provides a draining board for a single-story roof that prevents rainwater from penetrating into the main interior as well as the interior of the flat.

An embodiment of the present invention will be described below based on the drawings.

The roof of the one-story house B is covered with flat tiles 3 on the top surface of a field board 1 via an asphalt roofing 2.

At the eaves of the one-story house B, a front hanging piece 61 of a reverse-shaped fascia hosui-kiri board 6 is hung in the shape of a fascia.

Thus, the front hanging piece 61 is provided with a vertical notch 61a at the lower part thereof at a position close to the mortar wall on the end side of the shed A.

A double presser 5 is attached to the joint between the mortar wall 10 and the single-story roof B via a cap 4.

Thus, both pressers 5 are formed in a two-stage shape in a front view cross section (as shown in the third figure), and the side rising pieces 51 are erected on the rear surface of the mortar wall 10.

This presser foot 5 has a first horizontal piece 52 that covers the top surface of the cap 4, a side hanging piece 53 that covers the opposite side of the cap 4, and a second horizontal piece 54 that is in contact with the top surface of the tile 3. Ru.

A hanging piece 55 extending along the front end of the cap 4 is formed at the front end of both pressers 5 along the roof slope.

Furthermore, a cross-sectional water section 7 is attached to its front surface with its rising section 71 in contact with the hanging section 55 and its bottom section 72 inserted between the tile 3 and the cap 4.

The mortar wall side edge of this water section 7 is embedded in the wall as shown in FIG.

The water section 7 and the eave side end surfaces of both pressers 5 are sealed off with caulking material 8.

Further, as shown in FIG. 3, the caulking material 8 is also applied to the second level horizontal piece 54 of both pressers 5 and the tile 3, and then watered.

Numeral code 9 is the rafter, 11 is the support beam, 12 is the rim, 13a,
13b, 13c, and 13d are fixing nails, and 14 is a scrap board.

During construction, the asphalt roofing 2 for waterproofing is fixed to the rim 12 forming the wall surface of the shed A by nailing from the outer surface of the side rising pieces 51 of both pressers through the side rising pieces of the waste board 14. Further, a mortar wall 10 is formed on the outside thereof by embedding the side edge of the water section 7.

In such a structure, the rainwater collected on both pressers 5 temporarily stops behind the rising piece 71 of the draining plate 7, but since the edge of the rising piece 71 is buried in the mortar wall 10,
The rainwater flows in the direction opposite to the wall and is discharged onto the flat roof tile 3.

As described above, since rainwater is temporarily stopped behind the rising piece 71, water tends to accumulate in this part, but at the same time, the accumulated water also tends to flow in the direction opposite to the wall, and does not seep into the mortar wall 10.

In addition, since rainwater traveling toward the wall 10 along the front hanging piece 61 of the drain plate 6 is blocked by the notch 61a, it does not travel any further and seep into the mortar wall 10.

In addition, as another embodiment, both presser foot 5 and water section 7 may be soldered,
Alternatively, it may be welded.

This idea is also applied when one-story building B is connected to the side wall surface of the eaves of main star A.

As described above, in the present invention, a fascia-cum-draining plate is attached to the tip of the eave of a one-story house along the length of the eaves, and the front hanging piece of the draining plate has a vertical notch at the lower part of the part adjacent to the mortar wall of the main star. As a result, rainwater traveling along the drain plate toward the mortar wall is blocked by the notch, and no longer enters into the mortar wall.
