Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a water leakage draining device for an outer roof portion suitable for a sunroom or an extension/renovation room.

(Prior art) Conventionally, when extruded aluminum alloy members are used as rafters that constitute a part of the roof when expanding or renovating a sunroom or study room, it is usually done using a split square 1 structure as shown in Figure 3. ,
The side edge of the roof material 5 is fitted into the rafter 4 formed of the ribbed edge 2 and the mullion sealing material 3, etc., and the side edge is attached to the split mullion 1 and the ribbed edge 2.
A bead 6 attached to the inner edge of the room and a caulking material 7 made of silicone rubber or the like seal the room to prevent rainwater from entering the room. 8 stands on one corner,
9 is a window frame, IO is a window glass, and 11 is a blind bracket.

(Problems to be Solved by the Present Invention) However, in this conventional method, the sealing material such as the caulking material 7 must be reliably installed, which not only makes this work difficult and time-consuming, but also prevents the rafter 4 A difference occurs between the internal pressure of the hollow part 12 and the external pressure, and rainwater flowing on the upper surface of the roofing material 5 enters into the hollow part 12 in a "splash" state from the seal part, which prevents water from entering the room. There was a problem in that it increased the infiltration of rainwater.

(Means for Solving the Problems) Therefore, the present invention has been made in view of the above-mentioned problems of the conventional art. Rainwater that has entered the rafters can be drained to the outside by opening one end of the drainage ditch and providing a roof leakage drainage device that communicates with an external drainage ditch formed in a J-shaped pipe attached to the eaves. This method solves the above-mentioned conventional problems by preventing the water from entering the room.

(Example) A connects the roofing material and connects the roofing material to the roof part A of the building.
The rafters are made of extruded aluminum alloy material, and drain grooves 21 and 21 are integrally formed on both sides of the rafters. The outer wall 21 of the drain 21.21
A bead 22.22 made of an elastic material is attached to the upper end of the roof member a, and the side line of the roofing material is placed on the core portion. Further, a fitting part 23 is erected in the center of the rafter a, and a mullion sealing material 24 that comes into contact with the upper surface of the side line of the roofing material is fitted into the fitting part 23. . 25.25 is a bead interposed between the mullion sealing material 24 and the roofing material.

The front and rear ends of the drain groove 21.21 are open, and the front end opening 21b is located on the eaves 26 side of the roof A.
21b is an external drainage groove 2 integrally formed with a fascia 27 formed of a steel material such as aluminum and attached to the part 26.
It is removed so that it communicates with 8.

In this embodiment, the front and rear ends of the drain groove 21 are opened.
The present invention is not limited to this, and only the front end of the drain 21 located on the eaves 26 side may be opened. A drainage groove is formed in the constituent rafters, and at least one end of the drainage groove is opened, and the Jl,lt! is attached to the eaves! ,t
, etc., so that even if rainwater flowing on the upper surface of the roof leaks, the leaked rainwater will flow through the drainage groove to the external drain and be discharged to the outside.

Therefore, the rainwater does not enter the room.

Further, according to the present invention, the drainage groove formed in the rafter communicates with the outside air via the external drainage groove, so there is no difference between the internal pressure of the drainage groove and the outside air pressure, which is different from the conventional method. ＜″
This phenomenon does not occur, and it is possible to prevent rainwater from entering the room.

Further, according to the present invention, since the structure allows rainwater to enter the rafters to some extent, caulking work can be omitted, making it easy to construct the roof and greatly shorten the construction time. It has the effect that it can be done.
