DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing an installation state of a sash frame of the present embodiment around a joint, FIG. 2 is an exploded perspective view of the sash frame around the joint, and FIG. FIG. 4 is a view taken along the line AA in FIG. 2, and the configuration of each component will be described first.

[0010] In the figure, reference numeral 1 denotes a rail body, which is installed in an opening 31 of a concrete skeleton 30 and has a slit formed in an edge 32 of the opening.

The rail body 1 is formed in a box shape having a substantially flat section in order to provide the inner groove 3, and a slit 2 communicating with the inner groove 3 is formed on one wide surface thereof over its entire length. I have. In the drawing, reference numeral 4 denotes an insertion opening formed on the slit forming surface side for inserting a locking portion 9 of a joint fitting 6 to be described later into the inner groove 3, and 5 denotes a projection protruding from the slit forming surface side to increase the adhesive force with concrete. It is an irregularly shaped projection provided.

Reference numeral 6 denotes a joint fitting, which in this embodiment comprises a slide portion 7 and a bracket portion 8.
The slide portion 7 is firstly made to protrude outside through a slit 2 and a locking portion 9 slidably mounted in the inner groove 3.
The connection seat 10 is formed in a substantially T-shape. The first connection seat 10 is provided with a long groove 11, one of which is cut out, in a direction orthogonal to the surface of the locking portion 9.

The bracket portion 8 is for mounting the sash frame 16 made of steel fittings.
The mounting portion 12 and the second connection seat 13 for screwing the fixing plate 18 inserted into the setting groove 17 from the outside of the setting groove 17 are formed in a substantially T-shape as described above. The second connection seat 13 includes the first connection seat 10.
The mounting portion 12 is provided with an elongated hole 14 corresponding to a tapped hole (not shown) of the fastening plate 18 in a direction orthogonal to the second connection seat 13.

Next, the operation will be described. First, the rail body 1 is pre-fixed to the temporary frame before the concrete is cast and on the indoor side stepped opening forming surface so that the slit 2 faces the opening forming surface, and then the concrete is poured from above. Cast in. In the present embodiment, the rails 1 are arranged on the upper side and the left and right sides forming the frame opening.

As a result, the rail body 1 after the escape from the temporary frame is
It is fixed to the concrete frame 30 with the slit 2 opened at the frame opening edge 32. In this case, the concrete projection 5 is firmly fixed by the concrete fixing action.

Next, the joint fitting 6 is appropriately arranged on the rail body 1. In this case, the locking portion 9 is inserted into the rail body 1 from the insertion opening 4 so that the sliding portion 7 of the joint fitting 1 is inserted.
The brackets 8 are arranged on the sash frame 16 at predetermined intervals, and are fixed with screws 21 to fix the fixing plate 18.
To secure it.

At the time of installing the fittings, the sash frame 16 is inserted into the frame opening 31 from the indoor side, and the first connecting seat 10 and the second connecting seat 13 are overlapped so that the bolt 19
The sash frame 16 is installed in the skeleton opening 31 by fastening the bracket 8 and the slide 7 with the nut 20. At this time, the adjustment of the installation position is performed using the long hole 15 provided in the bracket part 8 in the front-back (in / out side) direction, and the long groove 11 in the up-down direction.
And adjustment using the elongated hole 14. This sash frame 16
After installation, urethane foam 35 is injected into the gap between the sash frame 16 and the frame opening edge 32 to be fixed and waterproof. 33 in the figure
Is a joint waterproof and 34 is a glass window fitted later.

As described above, in the present embodiment, the sash frame 16 is installed by using the rail 1 attached to the temporary frame and the joint fitting 6 whose level can be adjusted. The installation can be performed easily without requiring a special technique such as a mounting welding technique.

Further, since the sash frame 16 is not fixed by welding or mortar as in the prior art, it is necessary to remove concrete around the sash frame or cut the welded rebars when exchanging fittings several decades later. Without removing the urethane foam, simply removing the screws after removing the urethane foam allows the frame to be easily detached even afterwards, making maintenance such as reforming easy. In addition, since the sash frame 16 can be detached from the inside of the building, there is no need to use a scaffold, the maintenance cost is reduced, and the time required for the work is reduced.

Although the embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the invention. This is also included in the present invention.

For example, as shown in FIG.
The connection seats 10 and 13 of the bracket part 8 may adopt another angle such as 45 degrees instead of 90 degrees. In this case, it is possible to oppose the acting force in both the vertical and horizontal directions.

Also, the mounting position is adjusted by using the width of the flat plate without using the long groove 11 or the long hole 14 to form a simple flat plate.
Instead of the bolt 19, a tapping screw 22 or the like may be used for fixing.

Although the sash frame has been described in the embodiment, the invention is not limited to the sash frame, and a steel frame such as a door can be similarly mounted, and a steel fitting can be easily installed.
