Description

[Detailed description of the invention] a. Purpose of the invention (industrial field of application) The aluminum sash bottom frame mounting bracket according to this invention is designed to be used inside the opening of a building with a steel frame panel structure constructed by attaching panels to a steel frame. Used when fixing aluminum sash framework around the circumference.

(Prior art) It has been widely practiced to fix aluminum sash frames inside openings such as windows and doorways of steel frame panel structures. For fixing, the framework was screwed to an anchor welded to the steel frame.

(Problem that the invention aims to solve) However, with this conventional structure for fixing aluminum sashes, not only is it troublesome to weld the anchors, but when the cross-sectional shape of the sash frame becomes complex, parts that need to be screwed are difficult to solve. As a result, the work of fixing screws between the anchor and the framework was troublesome. especially,
When a decorative picture frame is further fixed to a frame fixed to a steel frame, the frame and the frame must also be screwed together, which makes the work extremely complicated.

The aluminum sash lower frame mounting bracket of the present invention eliminates these inconveniences and makes it easy to connect the lower frame and the steel frame of the aluminum sash frame, as well as the lower frame and the picture frame. It is something to do.

b. Structure of the invention (means for solving the problem) The metal fittings for attaching the lower frame of the aluminum sash of the invention are formed as shown in FIG. That is, a first standing wall 3 perpendicular to the substrate section 2 is formed on one end edge of the substrate section 2 in which a long U-shaped first notch 1 is formed in the center, and a first vertical wall 3 is formed on the upper surface of the other end of the substrate section 2. A second standing wall 4 is formed in the area. This second standing wall 4 has a wide upper half and a narrow lower half, and the lower half has a shape in which the side where the first notch 1 is formed has been cut off. There is. A top plate portion 7 parallel to the base plate portion 2 is provided between the upper end edge of the first vertical wall 3 and the intermediate side surface of the second vertical wall 4 described later. A first small hole 5 is formed in the upper center of the first vertical wall 3, and a second notch 6 in the shape of a long U is formed in the middle part thereof and is offset to the same side as the first notch 1. ing. Further, a second small hole 8 is bored in the upper half of the second vertical wall 4 located above the top plate part 7.

Furthermore, in the illustrated embodiment, the first vertical wall 3
A horizontal projecting wall 9 is formed at the lower part of the outer surface of the second notch 6, and protrusions 10, 10 of the same height are formed above and below the second notch 6, sandwiching this notch 6. Further, a projecting wall 11 is formed at the end edge of the top plate portion 7 on the first vertical wall 3 side.

On the other hand, as shown in FIG.
A lip groove 15 is formed in which the holder 4a can be engaged.

(Function) The lower frame of the aluminum sash frame and the frame are fixed to the steel frame using the aluminum sash lower frame mounting bracket of the present invention constructed as described above in the following manner.

First, in order to fix the steel frame and the lower frame,
6, a support plate 18 having a shape as shown in FIG. 4 and having a screw hole 17 in the center is inserted. Since the width of the opening in the steel frame 16 is narrower than the width of the space inside the steel frame 16, if the support plate 18 is inserted through the opening and then rotated 90 degrees, the support plate 18 can be removed from the opening. There isn't. A bolt 19 is screwed into the screw hole 18 at the center of the support plate 18 engaged with the steel frame in this way.
9 into the first notch 1 of the base plate 2 of the metal fitting 12
and tighten this bolt 19. As a result, the base plate 2 of the metal fitting 12 and the support plate 18 strongly clamp the upper sides 20, 20 of the steel frame 16, and the metal fitting 12 is fixed to the steel frame 16.
The metal fittings 12 fixed to the steel frame 16 in this way
In this case, the lower frame 21 of the aluminum sash frame is fixed using screws or rivets. That is, in the illustrated example, the small hole bored in the first hanging wall 22 formed on the outdoor side (left side in FIG. 2) of the lower frame 21 and the metal fitting 1
The rivet 23 inserted through the first small hole 5 drilled in the center of the upper part of the first vertical wall 3 of No. 2 is caulked, and the second vertical wall 4 of the metal fitting 12 is attached to the second hanging wall 24 formed on the indoor side. The lower frame 21 is fixed to the metal fitting 12 by screwing and tightening a screw 25 inserted through a second small hole 8 bored in the center of the upper part.

Furthermore, a lip groove 1 formed on the indoor side of the picture frame 13
5, the bolt 14 fitted with the head 14a is attached to the metal fitting 12.
A nut 26 is inserted into the second notch 6 of the first vertical wall 3 and is tightened by screwing into a threaded portion that protrudes toward the indoor side from the first vertical wall 3. As a result, the indoor side surface of the picture frame 13 is connected to the protrusions 10, 10 formed on the outer surface of the first vertical wall 3 of the metal fitting 12 and the lower frame 21.
is strongly pressed against the outdoor side of the picture frame 13 and the lower frame 21
It is also fixed to the metal fitting 12.

Bolt 1 for fixing the metal fitting 12 to the steel frame 16
9 and the nut 26 for fixing the picture frame 13 to the metal fitting 12, since the width of the lower half of the second vertical wall 4 on the indoor side of the metal fitting 12 is narrow, a wrench is required. It is easy to insert tightening tools such as

In addition, in the above explanation, since the metal fittings 12 are fixed to the steel frame 16, the support plate 18 is used.
When the opening of the steel frame 16 faces downward, the metal fitting 12 is fixed to the steel frame 16 with bolts 19 and nuts 27, as shown in FIG.

Also, when assembling the aluminum sash frame in the factory, if the metal fittings 12 and the frame 13 are screwed to this frame, the work required to erect the frame on site is just the steel frame 16 and the metal fittings. 12 with bolts, and the work of erecting the aluminum sash frame at the construction site is significantly simplified.

c Effect of the invention Since the aluminum sash lower frame mounting bracket of the invention is constructed and used as described above,
The work of fixing the lower frame of the aluminum sash and the picture frame to the steel frame can be easily performed.
