CONSTITUTION: An upper surface shape of an upper frame 2 and an under surface shape of a lower frame 3 are respectively formed in a step shape, and vertical frames 4 and 4 are formed by integrally arranging an installing piece on an outside surface of a vertical plate, and the upper frame 2 and the lower frame 3 are butted against upper and lower parts of a vertical plate inside surface, and are connected to each other, and are formed as sash frames 1 and 1. Next, an upper surface of the upper frame 2 of a lower sash frame 1 and an under surface of the lower frame 3 of an upper sash frame 1 are sealed by an intermediate dry sealing material 33 and an outdoor side dry sealing material 34. This intermediate dry sealing material 33 is projected outside from a vertical plate of the vertical frames 4, and is brought into pressure contact with it so as to stride over an installing piece indoor side surface of the upper and lower vertical frames 4. A vertical frame reinforcing material is connected through the dry sealing material so as to stride over the vertical plate of the upper and lower vertical frames 4 and the installing piece indoor side surface.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing structure for connecting portions of step windows.

[0002]

2. Description of the Related Art A stepped window is formed by vertically connecting sash frames. Specifically, the upper frame, the lower frame, and the left and right vertical frames are formed into a square shape to form a sash frame, and the upper frame of the lower sash frame. It is known that the lower frame of the upper sash frame is connected and the connecting portion is sealed with a sealing material.

[0003]

Since the sash frame is connected to the vertical frame by abutting the end faces of the upper and lower frames, the upper and lower end faces of the vertical frame slightly project from the upper face of the upper frame and the lower face of the lower frame.

Further, the vertical frame is provided with a mounting piece for mounting the body,
The mounting piece projects outward in the in-plane direction from the upper and lower frame connecting surfaces of the vertical frame.

Therefore, in order to seal the connecting portion of the stepped window, the upper and lower frame upper and lower frame lower sash frames, the upper and lower vertical frame upper and lower surfaces, and the upper and lower vertical frame attachment pieces are sealed. Since the upper and lower surfaces are sealed, conventionally, the above-mentioned respective parts are sealed by a wet sealing material after the step window is assembled.

As described above, the work for mounting the wet sealing material is very troublesome, and an error in mounting the wet sealing material is likely to occur, resulting in poor reliability.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a sealing structure for connecting portions of step windows which can solve the above-mentioned problems.

[Means for Solving the Problems] The top shape of the upper frame and the bottom shape of the lower frame are each made into a staircase shape, and the vertical frame has an attachment piece integrally provided on the outer surface of the vertical plate. The upper and lower frames are butted against the upper and lower parts of the inner surface of the plate to connect them to form a sash frame,
The upper surface of the lower frame of the lower sash frame and the lower surface of the lower frame of the upper sash frame are sealed with an intermediate dry seal material and an outdoor dry seal material, and this intermediate dry seal material is projected outward from the vertical plate of the vertical plate to raise and lower. Sealing structure of the stepped window in which the vertical frame reinforcing member is pressure-welded across the indoor side surface of the vertical frame, and the vertical frame reinforcing material is connected via the dry seal material across the vertical plate outer surfaces of the upper and lower vertical frames and the outdoor side surface of the vertical frame. .

[0009]

[Operation] A space between the upper surface of the upper frame and the lower surface of the lower frame is sealed with an intermediate dry seal material and an outdoor dry seal material, and the vertical plate between the upper and lower vertical frames is a dry seal material, and is perpendicular to the dry seal material. Sealing is performed with a dry sealing material to be crimped to, and the upper and lower surfaces of the mounting pieces of the upper and lower vertical frames are sandwiched between the intermediate dry sealing material and the dry sealing material for sealing. Thereby, the connecting portion of the step window can be reliably sealed by the dry sealing material.

Next, the sash frame 1 is moved up and down as shown in FIG.
The continuous windows connected to the left and right will be described. (When connecting the continuous windows up and down to form a continuous window) As shown in FIG. 10, the vertical frames 4 of the left and right sash frames 1 are connected by the upright 60, and the upper surface 60a of the upright 60 is an upper frame. 2 is cut into a staircase shape according to the upper surface shape, and the lower surface of the upright 60 is cut into a staircase shape according to the lower surface shape of the lower frame 3 to form a continuous window. The structure of this continuous window is conventionally known, for example, an actual open flat 6-
It is the same as that shown in Japanese Patent No. 51471.

Next, the sealer 61 is straddled over the outdoor side portion on the upper surface 60a of the upright 60 and the outdoor side horizontal plates 5 of the left and right upper frames 2.
And the upper surface 60a and the lower surface of the upper and lower uprights 60 are contacted and sealed via the sealer 61, and the upper frame 2 and the lower frame 3 of the upper and lower sash frames 1 are respectively separated in the same manner as in the case of the above-mentioned step window. connect.

In this case, the connecting member 25 is the left and right sash frames 1.
Since it is mounted over the connecting member 25, as shown in FIG.
Vertical locking pieces 31 and 32 and the upright 6 on the projecting piece 25a
The part facing 0 is cut out as shown in perspective to form a cube 60.
Try not to interfere with.

(When connecting the step windows to the left and right to form a continuous window) As shown in FIG. 12, the upper and lower sash frames 1 are connected in the same manner as the above-mentioned step windows. As indicated by the diagonal lines, the portions of the mounting pieces 42 of the upper and lower vertical frames 4 that protrude from the intermediate engaging projections 44 and the other side piece 52 of the vertical frame reinforcing member 50 are deleted to remove the upper and lower vertical frames 4. It is possible to connect with one cube 60.

Further, the end portions of the cover material mounting pieces 14 of the upper frame 2 and the end portions of the cover material mounting pieces 24 of the lower frame 3 are notched as shown by the diagonal lines in FIG. An air gap is formed between 40 and 40.

As shown in FIG. 13, the right and left step windows are set up in a vertical direction 60.
And the vertical cover 62 is attached to form a continuous window. Since the vertical covers 62 are attached so that the vertical strips 63 on both sides are in contact with the inner surfaces of the vertical plates 40 of the left and right vertical frames 4, the end portions of the cover mounting strips 14 and 24 are notched.
