BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting bracket which can firmly and easily attach an aluminum sash to a window hole of a wall of a reinforced concrete structure.

[0002]

2. Description of the Related Art It is stipulated by law that a sash used for a window of a reinforced concrete structure should be firmly installed around a reinforcing bar of a wall body so as not to fall off during an earthquake or the like.

When the sash is made of iron, the sash may be welded to the reinforcing bar projecting from the window hole of the wall body. However, when the sash is aluminum, it is difficult to weld the sash directly to the reinforcing bar. , Was attached as shown in FIG.

In both figures, the window hole 2 provided in the wall 1 is covered with an iron mounting plate 3, and the mounting plate 3 is welded in advance to the relevant portion by penetrating the end portion of the fixed frame 4. , Wall 1
When the concrete is poured, the fixed frame 4 is embedded so that the wall 1 is firmly fixed.

Reference numeral 5 is an aluminum sash having the same shape as the window 2 but smaller than the window 2, and a mounting groove 6 which is continuous over the entire circumference is formed on the outer peripheral surface.

Reference numeral 7 is a conventional mounting member, and a connecting portion 9 which also functions as a reinforcement is bent at one end of a support plate 8 having a substantially rectangular shape.
The end portions on both sides of the connecting portion 9 of the support plate 8 are cut and bent at the central portions to form the sandwiching portions 10 and 10.

The fitting 7 can be slidably attached to the aluminum sash 5 in the longitudinal direction by engaging both the sandwiching portions 10 and 10 with both side edges of the attachment groove 6 of the aluminum sash 5.

To attach the aluminum sash 5 to the window hole 2, first insert the aluminum sash 5 into the window hole 2 and temporarily fix the aluminum sash 5 at a predetermined position with an appropriate spacer (not shown) such as a piece of wood, and then attach the metal fitting 7 Is attached with the connecting portion 9 facing outward.

Next, as shown in FIG. 5, an iron connecting frame 1
From the side, attach the V-shaped bent portion 11a at the end of
And the mounting plate 3 of the window hole 2 and both ends of the bent portion 11a are welded to the supporting plate of the mounting bracket 7 and the connecting portion 9 and the mounting plate 3, and then the inner side of the side surface of the aluminum sash 5 is L. -Cut at the L line.

Then, if the spacer is removed and the space between the aluminum sash 5 and the wall 1 is filled with mortar, the aluminum sash is fixed.

[0011]

However, the mounting means of the aluminum sash 5 described above is used for the connection frame 11 at the construction site.
Since it was necessary to repeatedly perform the work of bending the tip of the above and the work of cutting from the LL line after welding, it was troublesome and the workability was poor.

[0012]

[Means for Solving the Problems] The present invention is characterized in that an end portion of an iron support plate of an iron mounting bracket mounted on an aluminum sash is
A connecting member consisting of an iron frame is pivotally mounted in the longitudinal direction of the aluminum sash so that the free end of this connecting member abuts the mounting plate of the window hole, and both ends are attached to the support plate. The above problems are solved by welding the plate or only the free end to the mounting plate.

[0013]

The function of the mounting bracket of the present invention is that the connecting member can swing in the longitudinal direction of the aluminum sash, so that the free end can be easily brought into contact with the mounting plate even if the space between the aluminum sash and the mounting plate of the window hole is not uniform. Can be welded together.

Moreover, the connecting member can be easily pivotally mounted on the supporting plate in the factory.

1 to 3 show an embodiment of the present invention. The same members as those in the above-mentioned conventional example are designated by the same reference numerals and the description thereof will be omitted.

Mounting bracket 21 of this embodiment corresponding to the above 7
Also on the support plate 22 of the above, the holding portions 2 similar to the above 10 are provided on both sides.
3, 23 are formed and are engaged with the mounting groove 6.

At one end of the support plate 22, instead of the connecting portion 9, one side of a rectangular annular connecting frame 24 connecting the aluminum sash 5 and the mounting plate 3 is slidable in the longitudinal direction of the aluminum sash 5. It is pivotally installed. The connecting frame 24 is
Any ring-shaped frame may be used as long as it is pivotally mounted on the support plate 22, and may be, for example, a substantially U-shaped frame having both ends on the pivot side.

The swinging radius of the connecting frame 24 is set to be equal to or larger than the distance between the support plate 22 and the mounting plate 3 when the aluminum sash 5 is temporarily fixed in the window hole 2 for mounting.

The mounting bracket 21 is made of aluminum sash 5
After temporarily fixing the inside of the window hole 2, attach the mounting bracket 21,
When the connecting frame 24 is swung, its free end abuts on the mounting plate 3, so that the aluminum sash 5 is connected to the mounting plate 3 by welding it.

At this time, if the pivotally connecting portion of the connecting frame 24 is welded to the supporting plate 22 at the same time, the aluminum sash 5 and the mounting plate 3 are more firmly connected.

[0021]

The mounting bracket of the present invention has a connecting frame for connecting the aluminum sash to the window hole of the wall body, which is pivotally mounted on the supporting plate in the longitudinal direction of the aluminum sash. When connecting the aluminum sash like the mounting bracket, it is not necessary to repeatedly bend or cut one end of the connecting frame at the construction site, and the workability of mounting the aluminum sash is significantly improved.

Further, since the mounting bracket of the present invention is provided with the connecting frame as the connecting member, it is lightweight, easy to handle, and inexpensive.

Further, since the mounting bracket of the present invention is provided with the connecting frame as the connecting member, even if there is an obstacle on the mounting plate in the window hole, the space portion of the connecting frame can prevent such obstacles. It can be avoided and relatively easy welding to the mounting plate is possible.
