Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for an external window frame that is externally attached to a frame opening.

[0002]

2. Description of the Related Art As rainwater drainage means for a window frame externally attached to an opening of a building or a window frame semi-externally attached, for example, a hollow portion is provided in a lower frame member and a drainage port is formed outside the hollow portion. However, it is known that a movable plate is freely opened and closed at the drain port, and the hollow part is used as a gutter to drain rainwater.As a means for draining condensed water, a drain block is attached to the lower outer periphery of the vertical frame member, It is known that the dew condensation water is collected in a drainage block and drained to the outside of the room. (For example, JP 61-198495, JP 61-47395, JP 1-131789, JP 3-5892)

[0003]

In the case of an external window frame or a semi-external window frame in which a drainage block is screwed to the lower outer periphery of a vertical frame member to drain condensed water, the block from the screw stop portion to the frame is used. There is also a problem that water infiltrates into the pipe, and because the outlet of the drainage block is directly exposed to the outside, wind and rain blow from the outlet of the drainage block to the outer periphery of the vertical frame material. The present invention has been made in view of such problems of the prior art, and its object is to provide a drainage device that can reliably drain dew condensation water while blocking the blowing of wind and rain. To provide.

When the lower frame member 2 is mounted on the vertical portion of the lower frame member 2 in the vertical direction, the caulking receiver 22 is mounted between the outer wall 2c of the lower frame member 2 and the lower member 5.

Since the drainage device in the external window frame of the present invention has the above structure, the window frame F corresponding to the size of the opening A is previously formed in the upper frame member 1, the lower frame member 2, and the vertical frame member 3. The window frame F is fitted into the opening A from the outside of the room, the upper frame member 1 is fitted to the upper building member D, and the swallow space 2f of the lower frame member 2 is fitted to the lower building member D. After fitting the swaged empty portion 3f of the vertical frame member 3 into the left and right building members D, a screw N is screwed into the building member D from the set plate 2g of the lower frame member 2 to open the window frame F in the opening A. Temporarily stop.

Next, the upper member 4, the lower member 5, and the vertical member 6, which are separately molded, are sequentially attached to the window frame F. For example, upper member 4
In that case, the leg piece 4a of the upper member 4 is joined to the outdoor side of the upper frame material mounting wall 1d, and the upper member leg piece 4a and the upper frame material mounting wall 1d are fixed to the upper building material D by screws N, In the lower member 5, the substrate 5a is joined under the lower frame member outer peripheral wall 2e, and the substrate 5a is fixed to the lower frame member outer peripheral wall 2e with screws N. At that time, the substrate 5a of the lower member 5 is extended to at least the outer peripheral void portion 13 of the vertical frame member 3,
The draining plate 5b is directed to the outdoor side, and the substrate 5a is placed on the outer peripheral wall 2e of the lower frame member 2.
While being circumscribed, the end surface excluding the substrate 5a is brought into contact with the door contact wall 3a of the vertical frame member 3, and a screw N is screwed into the lower frame member outer peripheral wall 2e from the substrate 5a and fixed.

In order to mount the vertical member 6 on the vertical frame member 3, the vertical frame member mounting wall 3d and the inner and outer pieces 8b of the vertical member hollow chamber 8 are preliminarily provided with screw insertion holes 3g, 8g in a communicating state, As shown in FIG. 6, if the decorative portion 9 of the vertical member 6 is directed toward the outer circumference and the insertion portion 7 is deeply inserted into the outer peripheral empty portion 13 of the vertical frame member 3, the insertion portion 7 of the vertical member 6 and the inner side of the hollow chamber 8 are separated from each other. It contacts the vertical frame member mounting wall 3d. In this state, from the insertion hole 8g of the hollow chamber 8 to the insertion hole 3g of the vertical frame member mounting wall 3d.
The vertical member 6 is fixed together with the vertical frame member 3 by screwing the screw N into the building material D via the.

When fitting the exterior material P on the upper frame member 1,
The sealing material S is interposed between the lower front plate p3 and the hanging projection p4 of the exterior material P so that the tip of the upper hook piece 4b of the upper member can be brought into close contact with the sealing material S and the lower frame member 2 When inserting the exterior material P below, the sealing material S is interposed between the hollow portion 5d of the lower member 5 and the leg wall 5f so that the tip of the exterior material swallowing portion p1 can be in close contact with the sealing material S. Is desirable. After mounting the vertical member 6,
It is desirable to insert the joint cover T on the outer side of the hollow chamber 8.

Even if wind and rain blows on the window frame F and a part of the wind and rain blows on the lower frame member 2, the wind and rain blows on the outer wall 2c of the lower frame member 2 and the draining plate of the lower member 5 attached to the lower frame member 2. As it is blocked at 5b,
It does not blow into the room, and the vertical frame member 3 and its outer peripheral empty space
Even if wind and rain blows from below into the vertical member insertion portion 7 inserted in 13, since the insertion portion 7 communicates with the outside air and is at atmospheric pressure, the wind and rain does not blow deeply into the insertion portion 7. The dew condensation water that flows down along the vertical frame member 3 is drained through the inner vertical gutter chamber 7a and the outer vertical gutter chamber 7b of the vertical member insertion portion 7 that is inserted into the outer peripheral empty portion 13 of the vertical frame member 3.

The structure of the external window frame of the present invention is not limited to the above example, and for example, the recess 5e is formed in the substrate 5a of the lower member 5.
If the sealing material S is attached to the recess 5e and the substrate 5a is attached to the outer peripheral wall 2e of the lower frame material, or if the sealing material S is attached to the indoor side of the vertical member 6 and attached together with the vertical member 6, it will be further improved. The waterproof effect is improved. Further, the upper frame member 1, the lower frame member 2, the vertical frame member 3, the shape structures of the upper and lower members 4, 5 and the vertical member 6 attached to them, and their attaching procedures, etc., are appropriately set unless they depart from the gist of the present invention. It can be changed.

[0020]

Since the drainage device in the external window frame of the present invention is constructed as described above, it has the following effects. The insertion part of the vertical member that is inserted into the outer peripheral empty part of the vertical frame member,
It is divided into an inner vertical gutter chamber and an outer vertical gutter chamber, and because it communicates with the outside air and is at atmospheric pressure, it does not blow deeply even if wind and rain blows. Moreover, dew condensation water can be reliably discharged. Further, since the vertical member is provided with a hollow chamber on the outer periphery of the insertion portion and the hollow chamber is attached to the building material, it can be strongly attached without affecting the drainage of rainwater or condensed water.
