Description

[Detailed description of the invention] Industrial application field This invention relates to a watertight device for the joint part of a Kasagi that covers a parapet on the roof of a building.

Prior Art Conventionally, the parapets on the roofs of buildings were covered with Kasagi to prevent rainwater from falling onto the parapets. Particularly in buildings with curtain walls installed, the top end of the curtain wall is located on the outside of the parapet, so unless it is covered with a cap, rainwater will enter the interior of the room through the gap between the parapet and the curtain wall. Resulting in.

However, since Kasagi arranges multiple pieces in succession,
Rainwater leakage from adjacent Kasagi must be prevented.

An invention described in Japanese Patent Application Laid-Open No. 53-83311 has been developed as such a joint watertight device for Kasagi. In this invention, an attachment is attached to the back side of the end of one of the adjacent caps, which continues in the width direction and whose end extends to the bottom of the other cap, and the space between the adjacent caps is sealed with a sealant. It is something.

Even if the sealing material between adjacent caps deteriorates and rainwater enters the back side of the caps from between the caps and the sealing material, the rainwater will fall onto the attachment and can be drained to the indoor or outdoor side of the parapet. be.

Problems to be Solved by this Invention The problem with the above invention is that before the spaces between adjacent caps were sealed with a sealant, rainwater would seep into the back of the caps, and even if they fell onto the attachments, a large amount of water would be released. If it is rainwater, it will overflow and seep into the indoor area. Therefore, there is a problem in that interior work cannot be done until the sealing between the Kasagima is completed, which delays the work accordingly.

Means for Solving the Problems The watertight device for the joint part of a Kasagi according to this invention has a groove opening upward on the back side of the end of the Kasagi adjacent to the Kasagi. Attachments each having a watertight material protruding to the side are fixed to each other, and a decompression chamber that is continuous in the width direction is formed by the groove and the back surface of the cap, and the opposing watertight materials are brought into contact with each other, so that the space between adjacent caps and attachments is fixed. is sealed with a wet sealant, and on the opposite side of the attachment to the adjacent cap, the gap between the attachment and the back of the cap is sealed with a wet sealant, and the bottom of one attachment is sealed to the bottom of the other attachment. It forms a protruding groove.

With the following configuration, before sealing the Kasagi-ma, it is sealed with a watertight material so that interior construction can begin, and if the sealing material deteriorates, a decompression chamber or wet sealing material is used to prevent rainwater from entering the room. This prevents water from entering the room.

Embodiment Hereinafter, this invention will be explained in detail based on an embodiment shown in the drawings.

In the figure, reference numeral 1 denotes a cap, which is placed so as to cover a parapet 2 and a curtain wall 3 attached to the outdoor side of the parapet 2. The curtain wall 3 is fixed to fasteners 4 fixed on the parapet 2 by bolts 5.

A plurality of Kasagi 1 are successively placed on the parapet 2. Attachments 6 are fixed to the back surfaces 1a of adjacent end portions of the caps 1 by welding.

The attachment 6 is provided with a groove 7 that opens upward and continues in the longitudinal direction. Below the groove portion 7, a lip groove 8 that opens toward the adjacent cap 1 side is formed continuously in the longitudinal direction. A watertight material 9 is attached to the lip groove 8 and is made to protrude toward the adjacent cap 1 side. The watertight material 9 is a dry packing and is a rubber member in which a locking portion 11 having an arrowhead shape in cross section is protruded from the side surface of a hollow portion 10 having a rectangular cross section. The watertight material 9 is attached with a locking portion 11 locked in the lip groove 8.

A horizontal portion 12 is formed on the opposite side of the groove portion 7 of the attachment 6 from the adjacent cap 1.
A hanging portion 13 that hangs downward is formed at the end.

Further, a groove 14 is formed in the attachment 6 to be welded to one of the adjacent caps 1, 1. The groove 14 projects from the bottom of the attachment 6 to below the other attachment 6. The tip of the groove 14 is slightly bent upward.

Attachment 6 is welded to the back of Kasagi 1,
The groove 7 and the back surface of the cap 1 form a decompression chamber 15 that continues in the width direction of the end of the cap 1.

On the opposite side of the attachment 6 from the adjacent cap, the gap between the attachment 6 and the back surface of the cap 1 is sealed with a wet sealant 16.

The caps 1, 1 are brought into contact with watertight materials 9, 9. Therefore, Kasagi 1, 1 and attachment 6,
Even if the gaps 6 are not sealed, the watertight materials 9, 9 prevent rainwater from entering. Rainwater that has entered through the gap between the watertight materials 9 and 9 falls into the groove 14, and the Kasagi 1
Water is drained from the widthwise end. Rainwater is watertight material 9,
9 prevents a large amount of rainwater from falling onto the grate 14,
Rainwater will not overflow. Yotsute Kasagi 1,
1 is attached and the watertight materials 9, 9 are brought into contact with each other, interior construction can be started.

A wet sealant 17 is used to seal between the caps 1 and 1 and the attachments 6 and 6.

If the sealing material 17 deteriorates, rainwater will enter the decompression chamber 15 through the gap between the back of the cap 1 and the attachment 6, but the pressure in the decompression chamber 15 is kept lower than outside, so the pressure difference between it and the inside is small. Therefore, it does not go over the side wall of the groove portion 7 and enter the indoor side. Rainwater flows through the groove 7 and falls from both ends of the cap 1 in the width direction.

Furthermore, on the side of the attachment 6 opposite to the adjacent cap 1, the back surface of the attachment 6 and the cap 1 is sealed with a wet sealant 16, so unlike a dry sealant, no gap is created.

Effects of the invention Since this invention has the above configuration, the following effects can be obtained.

○B Since the watertight materials of the adjacent attachments are brought into contact with each other, interior work can be started even before the caps are sealed, and the building construction work will not be delayed.

○B Because a decompression chamber is formed by the groove of the attachment and the back side of the Kasagi, even if the sealing material deteriorates and rainwater infiltrates through the gap between the attachment and the back side of the Kasagi, it will go over the side wall of the groove and enter the indoor side. There's nothing to do.

○C. On the opposite side of the attachment from the adjacent cap, the gap between the cap and the attachment is sealed with a wet sealant, which makes it difficult for gaps to form and completely prevents rainwater from entering the room.
