Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sealing device between frames that maintains airtightness and watertightness between an upper frame and an intermediate frame, and between an intermediate frame and a lower frame.

Prior Art As a sealing device between upper and lower adjacent frames, a device is known in which a tongue-shaped airtight material is attached to one frame and this airtight material is brought into contact with the other frame. Similarly, in order to maintain airtightness and watertightness between the upper frame and the intermediate frame and between the intermediate frame and the lower frame, airtight materials may be attached to the upper frame and the intermediate frame, respectively, as described above.

However, if the airtight materials are attached to the upper frame and the intermediate frame as described above, it is difficult to ensure that each airtight material contacts the intermediate frame and the lower frame, and rainwater may blow in from between the frames. In addition, each airtight material may be exposed to the outside, resulting in poor appearance, or may be exposed to wind and rain, causing early deterioration.

Purpose of the invention: It is possible to ensure that each airtight material is in contact with the intermediate frame and the lower frame, and to prevent each airtight material from being visually visible from the outside, resulting in poor appearance, and from being directly exposed to wind and rain. The purpose is to prevent premature deterioration due to lack of quality.

Composition of the idea: An upper airtight material and an intermediate airtight material are attached to the upper frame and the middle frame, which are bent into a dogleg shape at the middle part.
The bent piece at the tip contacts the corner of the intermediate frame and the corner of the lower frame, and a hanging piece is integrally formed on the upper frame to a position covering the upper and intermediate airtight materials.

Embodiment FIG. 1 is a front view of a unit type curtain wall, in which the curtain wall unit A is equipped with a spandrel unit B and a window unit C, and the window unit C is equipped with a fitted window _C1 and a sliding window _C2 . There is.

FIG. 2 is a detailed cross-sectional view taken along the line - in FIG.
The shoji lower stile 1 of the sliding window _C2 serves as an upper frame, the lower window frame 2 serves as an intermediate frame, and the upper frame 3 of the spandrel unit B serves as a lower frame.

The lower stile 1 of the shoji is an indoor wall 4 bent in a step-like manner.
and an outdoor side wall 5, a hanging piece 6 is integrally formed continuously with the outdoor side wall 5, and a lower horizontal piece 4a of the indoor side wall 4 is provided.
An upper airtight member 7 is attached to the upper airtight member 7.

The window frame lower frame 2 has a substantially U-shape with a vertical wall 8 and upper and lower horizontal walls 9, 10, and the upper horizontal wall 9 has a horizontal airtight material 1.
1 is attached, and an intermediate airtight material 12 is attached to the lower horizontal wall 10.

The upper frame 3 has a hollow shape with indoor and outer walls 13 and 14 and upper and lower walls 15 and 16, and the upper wall 15
are the upper horizontal piece 15a, the middle vertical piece 15b, and the lower horizontal piece 15c.
A horizontal airtight member 16 bent into a step-like shape and attached to the upper horizontal piece 15a is in pressure contact with the lower horizontal wall 10.

The upper airtight material 7 is bent toward the indoor side at the intermediate portion to form a substantially dogleg-like tongue shape with the base end bending piece 7a and the tip bending piece 7b, and the tip bending piece 7b is bent in the longitudinal direction. The middle part is the tip corner part 10a of the lower horizontal wall 10
The horizontal airtight material 11 is in pressure contact with the upper vertical piece 4b of the indoor side wall 4 of the shoji lower stile 1 to form a space 17.

The intermediate airtight material 12 has a hanging piece 12a and a bent piece 1 at the tip.
2b, it becomes a tongue piece that is bent in a substantially dogleg shape at the middle part, and the longitudinally intermediate part of the tip bent piece 12b is the corner part 1 of the upper horizontal piece 15a and the middle vertical piece 15b.
5', and forms a space 18 between the horizontal airtight member 16 and the horizontal airtight member 16.

The hanging piece 6 extends slightly below the corner portion 15' and is located on the outdoor side of the upper and middle airtight members 7 and 12.

Since the upper airtight material 7 and the intermediate airtight material 12 are in line contact with the lower horizontal wall tip corner 10a of the window frame lower frame 2 and the upper wall corner 15' of the upper frame 3, they are securely There is no chance of rainwater blowing into it by contact.

Further, the tip of the tip bent piece 7b of the upper airtight material 7 protrudes downward toward the outdoor side from the tip corner 10a of the lower horizontal wall 10, and the tip of the tip bent piece 12b of the intermediate airtight material 12 is connected to the upper wall 15. The projecting portions project downward toward the outdoor side beyond the corner portions 15', so that rainwater flowing along the tip of the lower horizontal wall 10 and the intermediate vertical piece 15b of the upper wall 15 can fall downward from each projecting portion. It has a water draining effect and also has a water draining effect when negative wind pressure is applied.

In addition, the hanging piece 6 has an upper airtight member 7 and an intermediate airtight member 12.
Since the upper air sealing material 7 and the intermediate air sealing material 12 are not visible from the outside, their appearance will not deteriorate, and since they are not directly exposed to wind and rain, the upper air sealing material 7 and the intermediate air sealing material 12 are located on the outside of the room. The airtight material 12 will not deteriorate early.

Note that notches, holes, etc. may be formed in the upper airtight material 7 and the middle airtight material 12 to make each space 17, 18 have the same pressure as the outside.

In this way, the sealing effect by the horizontal airtight members 11 and 16 will be excellent.

Effect of the invention The tip bent piece 7b of the upper airtight material 7 attached to the upper frame is the tip corner portion 1 of the lower horizontal wall 10 of the intermediate frame.
0a, and the contact state is a line contact, so there is reliable contact, no rainwater blows in, and airtightness and watertightness between the upper frame and the intermediate frame can be maintained.

The bent piece 12b at the tip of the intermediate airtight material 12 attached to the intermediate frame contacts the corner 15' at the tip of the upper wall 15 of the lower frame, and the contact is a line contact, so the contact is secure and rainwater does not blow in. There is no airtightness and watertightness between the middle frame and the lower frame.

Further, the tip bent piece 7b of the upper airtight member 7 is connected to the lower horizontal wall 1.
0 protrudes downward from the tip corner 10a toward the outdoor side,
Since the tip bent piece 12b of the intermediate airtight material 12 protrudes downward toward the outdoor side from the tip corner portion 15' of the upper wall 15, each tip bent piece 7b, 12b and the tip corner portion 1
0a, 15', the rainwater blown into the outside of the room can be caused to fall downward along the protruding portion, and has a draining effect, and when receiving negative wind pressure, each bent piece 7b, 12b is spaced apart from the tip corner portions 10a, 15', and has a drainage effect in which rainwater accumulated on the upper horizontal wall 10 of the intermediate frame and the upper wall 15 of the lower frame flows down from the inclined outdoor side tip portion to the outdoor side.

Since the upper airtight member 7 and the intermediate airtight member 12 are covered with the hanging piece 6, the upper and middle airtight members 7 and 1 can be accessed from the outside.
2 is not directly visible, is not directly exposed to wind and rain, and does not deteriorate in appearance or deteriorate early.
