Description

[Detailed description of the invention] The present invention relates to a mounting structure for the outdoor side of the lower frame of the sash, and its purpose is not only to prevent water leakage since it is located on the outdoor side, but also to maintain sufficient strength and improve productivity. It is about contributing.

Embodiments will be described in detail below with reference to the drawings.

FIG. 1 is a side sectional view showing a state in which the lower frame of a window frame sash is attached and fixed to an opening of a building by implementing the present invention, and the window shoji is an embodiment of a rotating window.

FIG. 2 shows part of the applicant's conventional method.

In the figure, 1 is the lower frame of the sash, and 2 is a shallow groove formed integrally with the lower end of the lower frame and has a rectangular cross section and is provided horizontally in the longitudinal direction.

The opening of the shallow groove is directed toward the outdoor side, and the groove bottom is vertical.

3 is an anchor metal fitting, and its outdoor side hangs downward to form a vertical mounting surface 3a, the other end hanging piece 3b is welded and fixed to the reinforcing steel 4 exposed from the building frame 5, and the indoor side end is a rising vertical piece. The figure shows the state in which the lower frame of the sash is supported and fixed on the indoor side.

Reference numeral 6 designates a draining plate, and its cross-sectional shape forms a downward slope toward the outdoor side.The tip of the waist is bent downward to provide a draining side 6a, and the indoor end has a vertical wall 6b for mounting. On the back of the
A pair of L-shaped locking pieces 6C that lock the drain plate support hardware 7 welded to the reinforcing bars 4 are each integrally formed.

8 is a decorative cover on the indoor side, and 9 is a mortar-finished surface on the outdoor side.

Next, to outline the installation and fixing of the lower frame 1, the vertical piece 1a on the indoor side of the lower frame 1 is screwed to the rising piece 3c of the anchor hardware 3 via the insulation material 10, and the intermediate leg 1b is screwed to the horizontal part of the anchor hardware 3. It is screwed at the bottom of the sash bottom frame 1.
On the outdoor side of the frame 1, the vertical wall of the shallow groove 2 with a substantially U-shaped cross section provided at the lower end is brought into contact with the vertical mounting surface 3a of the anchor hardware 3 and screwed from the outside with screws 11 to make the lower frame 1 strong. was fixed to the anchor hardware 3.

Next, after locking the draining plate 6 to the support hardware 7, the vertical wall 6b of the draining plate 6 is brought into close contact with the upper and lower edges 2a of the U-shaped shallow groove, and then It penetrates the lower frame and is directly screwed onto the anchor hardware 3.

In this case, in the conventional method, as shown in Figure 2, there is no U-shaped shallow groove, so countersunk screws are used and the surface of the lower frame 1 needs to be countersunk each time so that the screw heads do not protrude. there were.

As a result, the strength was reduced by that amount.

Finally, the space between the lower frame and the surface of the draining plate is filled with caulking material 12 to make it waterproof.

Also, caulking is applied in the same manner between the outer wall finished surface 9 and the draining plate 6a of the draining plate 6.

Note that the connecting portion 1c at the center of the lower frame is eventually torn off and the internal space is filled with a heat insulating material.

As explained above, by integrally molding the mounting piece with shallow grooves formed in the lower frame 1, this is a practical idea that not only improves productivity but also makes the attachment of the lower frame and draining plate even stronger.
