Next, a method of attaching the sash to the sash attachment space portion using the sash attachment fitting 1 will be described. For example, as shown in FIG. 11, the sash mounting metal fitting 1 is mounted on each corner portion of the sash mounting space portion K of a building which is formed to fit a square sash S therein. This attachment is performed by driving concrete nails, which have passed through nail holes provided in the base frame 2 of the attachment fitting 1, into the peripheral wall portion of the space K.

On the other hand, a sash anchor 50 is attached to each side of the sash S to be installed in the space K. The sash anchor 50 is for connecting the sash S and the mounting bracket 1, and It is fitted and fixed in the groove. In the illustrated example, it is formed in a plate shape (may be another shape) that fits into the grooved frame of the sash S, and a screw hole 51 is provided in the center thereof. As many sash anchors 50 as the number of the mounting brackets 1 are attached.

Sash S with sash anchor 50 attached
Is fitted into the sash mounting space K of the building, and the bolt 29 inserted into the screw hole 28 provided in the central portion of the fixing member 20 of each mounting member 1 is screwed into the screw hole 51 of the sash anchor 50. As a result, the sash S is in a state of being supported by a plurality of (four in the illustrated example) mounting fittings 1 provided at each corner portion.

When the sash is supported by the plurality of mounting members 1, the first and second slide frames 3 and 4 of these mounting members are slid to adjust the vertical and horizontal positions of the sash S. This adjustment is performed by the shafts 31a, 4a of the bevel gear device.
It can be performed by turning 1a. The position of the sash S in the inner and outer directions is determined by the bolt 25 of the fixing member 20.
It can be adjusted by turning. Since these adjustments can be performed by rotating the forward and reverse directions with a driver using the driver groove of the head of each shaft, it can be performed easily and accurately.

When the sash is fixed at a predetermined position, concrete is poured into the gap between the sash and the peripheral wall of the space. As a result, the sash mounting bracket 1 is embedded in concrete, and the sash is firmly fixed. Since the sash mounting bracket 1 has a relatively simple structure and can be manufactured at low cost, the cost will not be so high even if it is embedded in concrete in this way, and the overall construction cost will be reduced because the efficiency is improved. You can do it.

According to this sash mounting method, the sash can be held in the space and the vertical and horizontal positions can be adjusted by a simple operation, so that the sash can be mounted easily and efficiently. Since this mounting method does not adjust and fix the position by the wedge driving amount as in the conventional method, no skill is required and even a beginner can quickly and accurately perform the construction. Furthermore, since welding is not required for attaching the sash, surrounding members are not damaged or soiled, and there is no fear of fire.

[0020]

As described above, according to the present invention, the fixing work of the sash, which has required a considerable amount of skill in the past and required a long time, can be performed quickly and highly accurately without requiring much skill. It became possible to do it. Further, since welding is not required for the sash attachment work, it does not have a bad influence on other members and is safe. Although welding can be omitted in the construction method of the present invention, it goes without saying that part of the welding may be fixed in some cases.
