The left vertical frame member 3 constituting the window frame F is shown in FIG.
As shown, a door contact wall 3a is provided between the inner wall 3b and the outer wall 3c, and a mounting wall 3d is protruded outward from a middle portion of the width of the door contact wall 3a, and between the mounting wall 3d and the outer wall 3c. 1cm wider than the thickness t of the exterior material
In addition to forming the outer peripheral space 13 having the above depth, a swallowing cavity 3f fitted to the outside of the left and right construction material D is formed on the room side from the mounting wall 3d. Since the right vertical frame member 3 ′ has a substantially symmetrical shape with the left vertical frame member 3, a detailed description is omitted, and in the following description, the vertical frame member 3 includes the left and right vertical frame members 3, 3 ′. Shall be considered.

The vertical member 6 attached to the vertical frame member 3 is shown in FIG.
An insertion part 7 to be inserted into the outer peripheral space 13 of the vertical frame member 3,
A hollow chamber 8 protruding from the inner peripheral portion of the insertion portion 7 on the indoor side, and a decorative portion 9 protruding from the outer periphery of the hollow chamber 8 and covering a side end of the exterior material P
It is composed of A partition 6a is provided in the insertion portion 7 of the vertical member 6, and the insertion portion 7 is divided into an inner vertical gutter chamber 7a and an outer vertical gutter chamber 7b. Is hollow room 8
A hook 9a protruding outward from the inner and outer pieces 8b and bending outward is formed with a folded piece 9b facing the interior.

The outer peripheral piece 8a of the vertical member hollow chamber 8 is extended upward so that the end surface of the upper member 4 can be closed by the extended outer peripheral piece 8a, and the upper member 4 and the lower member 5 have screw pockets 4c, 5c.
If the screw N is screwed into the screw pockets 4c and 5c of the upper and lower members 4 and 5 from the extended outer peripheral piece 8a, the vertical member 6 can be further strongly fixed. As shown in FIG. 4B, when the upper frame member 1 is in a cubic portion that is continuous left and right, the cubic cover 21
The caulking receiver 22 is mounted between the outer wall 2c of the lower frame member 2 and the lower member 5 in the cubic portion where the lower frame member 2 is continuous left and right.

Since the drainage device for the external window frame according to the present invention has the above structure, the upper frame member 1, the lower frame member 2, and the vertical frame member 3 have a window frame F corresponding to the size of the opening A in advance. The window frame F is fitted into the opening A from the outside, and the upper frame 1 is fitted into the upper construction material D, and the swallowing space 2f of the lower frame 2 is fitted into the lower construction material D. After fitting the swallowing empty portion 3f of the vertical frame material 3 to the left and right construction material D, a screw N is screwed into the construction material D from the bottom plate 2g of the lower frame material 2, and the window frame F is opened to the opening A. Temporarily.

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 the above, the leg 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 4a and the upper frame material mounting wall 1d are fixed to the upper construction material D with screws N, and In the lower member 5, the substrate 5a is joined below the lower frame outer peripheral wall 2e, and the substrate 5a is fixed to the lower frame 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 space 13 of the vertical frame member 3,
The draining plate 5b faces the outdoor side, and the substrate 5a is placed on the outer peripheral wall 2e of the lower frame member 2.
And the end face except the substrate 5a is abutted against 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 attach the vertical member 6 to the vertical frame member 3, screw insertion holes 3g and 8g are drilled in advance in the vertical frame member mounting wall 3d and the inner and outer pieces 8b of the vertical member hollow chamber 8, respectively. As shown in FIG. 6, if the decorative portion 9 of the vertical member 6 is directed to the outer periphery and the insertion portion 7 is inserted deeply into the outer peripheral space 13 of the vertical frame member 3, the insertion portion 7 of the vertical member 6 and the indoor side of the hollow chamber 8 become It comes into contact with the vertical frame material mounting wall 3d. In this state, the insertion hole 8g of the hollow chamber 8 extends through the insertion hole 3g of the vertical frame material mounting wall 3d.
A screw N is screwed into the construction material D through the above, and the vertical member 6 is fixed together with the vertical frame material 3.

When fitting the exterior material P on the upper frame material 1,
A sealing material S is interposed between the lower front plate p3 and the hanging ridge p4 of the exterior material P so that the tip of the upper member upward hook 4b can be in close contact with the sealing material S, and When the exterior material P is inserted below, a 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 attaching the vertical member 6,
It is desirable to insert the joint cover T outside the hollow chamber 8.

Even if the wind and rain is blown onto the window frame F and a part of the wind is blown into the lower frame member 2, the wind and rain will cause the outer wall 2 c of the lower frame member 2 and the draining plate of the lower member 5 attached to the lower frame member 2. Since it is stopped at 5b,
It does not blow into the room, and the vertical frame material 3 and its outer peripheral space
Even if the wind or rain blows into the vertical member insertion portion 7 fitted into the thirteen from below, the rain is not blown deep into the insertion portion 7 because the insertion portion 7 communicates with the outside air and is at an equal pressure. The dew water flowing 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 inserted into the outer peripheral space 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. 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 concave portion 5e and the substrate 5a is attached to the outer peripheral wall 2e of the lower frame member or the sealing material S is attached to the indoor side of the vertical member 6 and attached together with the vertical member 6, it can be further improved. The waterproof effect is improved. Further, the shape and structure of the upper frame member 1, the lower frame member 2, the vertical frame member 3, the upper and lower members 4, 5 and the vertical member 6 to be attached thereto, and the procedure for attaching them are not limited as long as they do not contradict the gist of the present invention. Can be changed.

[0020]

The drainage device in the external window frame according to the present invention is constructed as described above, and has the following effects. The insertion part of the vertical member to be inserted into the outer peripheral space of the vertical frame material,
Since it is divided into an inner downspout room and an outer downspout room and communicates with the outside air and is at an equal pressure, it does not blow deep even if wind and rain blows. In addition, dew water and the like can be reliably drained. 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 construction material, the vertical member can be strongly attached without affecting drainage of rainwater or dew water.
