Description

[Detailed Description of the Invention] The present invention relates to the structure of a mounting portion for attaching a rim to a mullion vertically fixed to a building frame.

In the conventionally known structure of this type of installation, a hollow rectangular body rim is mounted in a mullion using bolts, etc., but it is complicated to drill holes and pressurize, and it is difficult to handle the inside of the hollow part of the body rim. Installation is difficult if it does not fit, and if the rim is thin, it cannot be installed unless the inner and outer surfaces of the hollow rectangular rim are penetrated with bolts.

The present invention was developed in consideration of the above-mentioned drawbacks, and uses an L-shaped cross-section fastener and a hook pole I, so that the rim can be easily attached to the mullion from the inside of the room.

The structure of the present invention will be explained in detail based on the embodiment shown in the drawings.A first angle member 2 and a second angle member 3 having vertical grooves on the vertical sides thereof are fixed on a frame 1, and A mullion 4 having a T-shaped cross section, an H-shaped cross section, or a T-shaped cross section (the ■-shaped cross section is shown in the figure) is arranged with the flange portion 5 facing outdoors, and the first angle member 2 is connected to the web of the mullion. The web part 6 is inserted into the notch groove 7 formed at the end of the part 6, and the web part 6 is inserted into the second
The mullions 4 are fixed to the frame 1 by fitting into the vertical grooves of the angle members 3.

The flanges 11 to be arranged on the outer surface 42 of the flange portion 5 of the mullion 4 at a predetermined interval in the direction perpendicular to the vertical direction have a bowler-hat-shaped cross section, and both end edges 13 of the flange portion 12 are It is formed into the shape of a Mexican hat.

It is convenient to make the rim from a thin metal plate such as an aluminum alloy.

Reference numeral 21 denotes fasteners disposed on both sides of the mullion web portion 6;
Hook ports 1 to insertion holes 22 are formed at both ends in the longitudinal direction, respectively, and the cross section is formed into a substantially upper shape consisting of an upright side 23 and a bent inclined side 24.

The stopper 21 is made of an elastic material such as steel.

The hook bolt 25 has a hook portion 26 at one end, a threaded portion 27 at the other end, and a collar 1-28.

When assembling, a rim 1 is attached to the outdoor surface of the flange portion 5 of the mullion 4.
The flange parts 12 of 1 are arranged in parallel to face each other, and the fasteners 21
The hook part 26 of the hook pol I/25 inserted into the insertion hole 22 of the body is hooked onto the upright edge 13 of the body edge, and the upright side 23 and inclined side 24 of the L-shaped cross section of the stopper 21 are connected to the body. Tighten the nut 28 by bringing it into contact with the indoor side surface of the flange portion 12 of the edge 11 and the indoor side surface of the cubic 4 flange portion 5.

Since the stopper 21 has elasticity, the metal itself springs back, and the reaction force caused by the tightening of the hook bolt 25 causes the upright side 23 of the stopper to move against the flange 12 of the body edge.
The slanted sides 24 elastically press the mullion flange portions 5, respectively, and elastically sandwich the mullion flange portions 5 between the stopper 21 and the flange portion 12 of the rim.

Furthermore, since the fasteners 21 are formed to have an L-shaped cross section as described above, both fasteners can be brought close to the web portion 6 side of the mullion by tightening the hook bolts 25, so that stable attachment of the rim to the mullion can be achieved. It will be done.

Opposite pawls 14 are formed on the exterior surface of the exterior side of the body rim 11 attached in this way, and the edge 18 of the exterior plate 17 is connected to the engagement portion 16 of the attached profile 15 by the pawls. It engages and supports using its elasticity.

Since the present invention is constructed as described above, the simple structure allows it to be easily installed in a mullion even with a relatively thin wall frame, and the spring-back property of the stopper allows the hook bolt to be stabilized without loosening. Fixation is obtained.

Moreover, since there is no need for welding, etc., all installation work can be carried out from inside the room, and has many other advantages.

Claims (1)

[Scope of utility model registration request] The structure of attaching a frame to a mullion vertically fixed to a building frame is a partial structure, in which the cross section of the mullion 4 is formed into a T-shape, H-shape, or T-shape, and the exterior of the mullion is On the outer surface of the flange portion 5, a rim 11 having a bowler hat-shaped cross section is arranged in parallel with the flange portions 5 and 12 facing each other, and a mulloidal web portion 6 is formed.
L-shaped cross-section fasteners 21 made of an elastic material are mounted on both sides of the
and the upright side 23 and the inclined side 24 constituting the L-shaped cross section of the stopper 21 are respectively arranged on the interior side surface of the flange section of the rim 11 ]2 and the interior side surface of the flange section 5 of the mullion 4. The mullion-shaped flange portion 5 is elastically held between the stopper and the flange portion 12 of the body rim via the respective hook poles 1 to 25 inserted into the stopper. The structure of the frame is attached to the mullion.
