JPH0622022Y2 - Water leakage prevention device for valley roof - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is to firmly support the straws on both sides of the valley where the left and right straw roofs form a valley and are connected to each other, and the rain leaks from the vicinity. The present invention relates to a device for preventing water leakage in a valley portion of a straw roof.

[Problems to be solved by conventional techniques and devices]

Conventionally, in a straw roof, when the roof surface and the roof surface are connected in a valley shape to form a valley, a water leakage prevention plate with both edges folded back is generally mounted on the roof surface of the valley. Place the straws on the left and right sides of the water leakage prevention plate, and prevent water leakage by interposing the water leakage prevention plate in the trough, and place the straws on the water leakage prevention plate. Since there is a water leakage prevention plate on the lower side, it can not be fastened by nailing, so extend the wire from the nail of the upper straw that was nailed and prevent it from slipping off by locking it with that wire. There is.

This work for stopping the straw is very troublesome, and improvement of this point has been demanded first.

Further, a gap is created between the water leakage prevention plate and the straw, and the water around which the water leakage prevention plate bypasses the water leakage prevention plate and leaks due to wind, rain, and snow cannot be avoided, and the water tends to leak.

SUMMARY OF THE INVENTION The present invention provides a device for preventing water leakage in a valley of a straw roof that solves the above drawbacks.

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

The water leakage prevention plate 4 is placed on the roof surface 3 where the left and right roof surfaces 3 on which the straws 5 are laid are connected in a valley shape, and a core metal or core is placed on the valley portion 2 of the water leakage prevention plate 4. A concrete gutter plate 7 having a length of a valley formed by incorporating a metal net 6 is placed, and a straw receiving ridge portion 8 is provided side by side on both left and right edges of the concrete gutter plate 7. Formed on the outside of the portion 8 is a locking step 9 for supporting the side edges of the straw 5 laid on both sides of the concrete gutter board 7, and between the straw receiving ridge 8 and the side edges of the straw 5 laid on both sides. Sealant that keeps airtight 10
The present invention relates to a device for preventing water leakage in a valley portion of a straw roof, which is characterized in that

[Action]

Rainwater collected in the valley portions of the straw roof 1 that are inclined to each other to form valley portions flows on the concrete gutter plate 7 and is drained.

Further, the side edges of the straws 5 laid on the left and right sides of the concrete gutter plate 7 abut on the straw receiving ridges 8 of the concrete gutter plate 7 and are supported by the locking step portions 9 outside the straw receiving ridges 8. .

For this purpose, the straws 5 on both the left and right sides of the concrete gutter board 7
Will be prevented from sliding towards the concrete gutter plate 7.

In addition, since the sealing material 10 for maintaining airtightness is packed between the straw receiving ridge portion 8 and the side edge of the straw 5, rainwater, melted water of snow or the like can be caught between the concrete gutter board 7 and the straw 5. Intrusion is prevented.

Since the water leakage prevention plate 4 is interposed below the concrete gutter plate 7, it is possible to prevent water from leaking to the valley portion of the base plate 11 below the water leakage prevention plate 4.

〔Example〕

The drawing shows an example of a preferred embodiment, in which a water leakage prevention plate 4 is placed on a roof surface 3 in which left and right roof surfaces 3 on which straws 5 are laid are connected in a valley shape. Valley 2 of 4
A concrete gutter plate 7 having a trough length formed by incorporating a cored bar or a cored wire net 6 therein is placed on the above, and the straw receiving ridges 8 are juxtaposed on both left and right sides of the concrete gutter plate 7. , The concrete gutter plate 7 on the outside of the straw receiving rib 8.
Steps 9 for supporting the side edges of the straw 5 laid on both sides of the
And the straws 5 that are laid on both sides
A sealing material (10) that keeps airtightness with the side edges is packed.

The water leakage prevention plate 4 shown in the drawing is a roof surface 3 which is formed by bending a stainless plate having a width in which a straw 5 and a concrete gutter plate 7 which are opposed to each other at a valley portion 2 are exactly aligned with each other in accordance with the bending of the valley portion 2 of the roof surface 3.
Place on top.

The concrete gutter plate 7 in the drawing shows a case in which a cored bar or a cored wire net 6 for preventing cracking of concrete is built in the concrete guttered plate 7 and formed into a substantially gutter shape.

On both edges of this concrete gutter board 7, straw receiving projections 8 which side end surfaces of the straws 5 abutting on both left and right sides abut, are arranged side by side, and outside the straw receiving projections 8 below the side edges of the straw 5. A stepped portion 9 is formed to support the side edge of the straw 5 whose corners are locked, and a shallow U-shaped concave portion 12 is formed on the upper surface between the left and right straw receiving ridges 8 to prevent water leakage from the bottom surface. It is formed in a shape corresponding to the bending of the valley portion 2 of the prevention plate 4.

As the sealing material 10 to be packed between the straw receiving ridge portion 8 and the side edge of the straw 5, a weathering-resistant architectural coating material such as rubber, epoxy resin, mortar or the like is used.

The drawing shows the case where the positions of both edges 4'of the water leakage prevention plate 4 are locked to the rear surface protrusions of the straw 5 in the third row. It may be locked to the part.

[Effect of device]

In the present invention, the left and right roof surfaces on which the straw is laid are laid in a valley shape, and a water leakage prevention plate and a concrete gutter board are laid in double in accordance with the valley part. Instead of directly hitting rainwater to the water leakage prevention plate, we adopted a method that allows rainwater to flow down by a concrete gutter plate on the water leakage prevention plate, and a sealing material is packed between the concrete gutter plate and the straw. However, since the sealing material is used to maintain the airtightness between them, the roof is less leaky than the conventional method.

Moreover, the straw laid on the water leakage prevention plate facing the valley is surely prevented from sliding inward by the straw receiving ridge and the locking step of the concrete gutter board, which is the same as the conventional method. It is not necessary to use nails to secure the upper straw with nails, and it is easy to lay the straw, and it is durable against snow, rain, wind, etc. to form a straw roof that does not leak or go around. It is intended to provide a device for preventing water leakage in a valley portion of a straw roof which is excellent in practicality.
