Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a metal sash mounted on an opening of a concrete frame or the like of a building.

[0002]

2. Description of the Related Art FIGS. 8 to 13 are sectional views showing a conventional sash mounting structure provided in an opening of a concrete skeleton. In the figure, 1 is the floor of the concrete frame, 2 is the underside of the beam,
3 is a wall, 4 is an opening, 5 (see FIGS. 8 to 11) is a sliding sash provided in the opening 4, 6 is a sliding door set up in the sash 5, 7 (FIGS. Reference numeral 8 is a fitting sash provided in the opening 4, 8 is a glass plate fitted in the sash 7, and 9 is a wooden frame provided inside each sash 5, 7.

[0003]

To attach the sashes 5, 7 to the opening 4 of the conventional concrete skeleton, the beam lower surface 2 of the opening 4 as shown in FIG. 8 and the wall as shown in FIG. Protrusions 10 projecting inwardly into the parts 3 respectively
(It is called "Daki" at the scene). In order to provide such a protrusion 10 on a concrete frame, the formwork used at the time of placing concrete becomes complicated, and the position of the protrusion 10 differs depending on the mounting position of the sash, which makes systemization of the formwork difficult. However, there is a problem that the construction period becomes long and the cost increases, and furthermore, since the opening area is reduced by the protrusion of the protrusion 10, there is a problem that the sense of grade of the building is deteriorated accordingly. Further, in the conventional frame shape of the sash, there is a problem that the finishing allowance for the work such as under the beam inside the room is reduced unless the duck is provided. The outer portions 11 of the sashes 5 and 7 are non-shrink mortar filled portions, 12 is a heat insulating material such as urethane foam on site, 13 is an interior material such as gypsum board, and 14 is a furring strip.

Further, as shown in FIG. 10, when the beam lower surface 2 of the opening 4 is made flat, a finishing allowance for the feature of providing a heat insulating material, a furring strip, etc. can be secured, but the upper frame of the sash 5 and the beam lower surface 2 Since the space between the mortar and the mortar becomes large, there is a possibility that a cavity will be created in the mortar portion depending on the construction, and if the cavity is created, there is a problem in that waterproofing or fire resistance occurs.

In order to solve the above problems, as shown in FIG. 11, if the upper frame 5a of the sash 5 is formed in the shape of a hollow box, the filling amount of the mortar is reduced and the possibility of cavities is reduced. However, there is a problem that the production cost of the sash 5 becomes high.

[0006]

In order to solve the above-mentioned problems, in the present invention, the opening edge of the concrete skeleton of the building is formed flat without providing an inwardly projecting projection. The height of the sash fitted in the opening is made higher than that of the conventional sash, and the outer shape of the frame-shaped outer plate of the sash is made larger than that of the conventional sash.

Further, a sealing receiving portion may be formed at the upper end of the outer plate of the upper frame of the sash of the first aspect of the invention, and an inner material mounting piece may be provided at the lower end of the inner plate.

The opening of the concrete skeleton of the first aspect of the invention may be formed under a beam or under a slab.

The sash of the first aspect of the invention may be a sash for pulling or a sash for fitting.

[0010]

As described above, according to the present invention, it is not necessary to provide an inwardly projecting protrusion (duck) at the opening of the concrete skeleton, and the edge of the opening may be formed flat. In addition to being simplified, the construction period is shortened and the cost is also reduced. Further, according to the present invention, since the opening area can be increased by the amount of the protrusion of the protrusion, the grade feeling of the building is improved accordingly.

Further, according to the present invention, since the space for filling the mortar does not become large, there is no possibility of forming a cavity in the mortar portion. Therefore, since it is not necessary to form the upper frame of the sash in the shape of a hollow box in order to reduce the space for mortar filling, it is possible to solve the problem that the production cost of the sash increases.
