Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a sash frame joining device mainly used for building sashes.

(Prior Art) Conventionally, as shown in FIG. 1, sash frames are connected by interposing a sealing material 2 of chloroprene rubber on a vertical frame 1 and screwing a horizontal frame 3 with pin screws 4, 4.
Especially if it is a building sash, as shown in Fig. 2, iron anchors 5,
5 is attached, and the anchor 5 and stud bolt 6 are welded to obtain the earth of the sash.

(Problem to be solved by the invention) By the way, in the combination of such satsushi frames,
While the vertical and horizontal frames are connected via a sealing material, the surface of the sash is generally painted or coated with an oxide film, so the vertical and horizontal frames are not energized even by the pin screws. Previously, it was difficult to ground the welding around the sash, where the welding between the iron anchor and the stud bolt had not been completed.

(Means for Solving the Problems) The present invention was made in view of the above-mentioned circumstances, and it is possible to connect sash frames by simply attaching the conductive plate of the vertical frame when screwing the vertical and horizontal frames. The device is designed so that it can be energized. In other words, the present invention is a sash frame coupling device in which a horizontal frame is screwed to a vertical frame having a pair of parallel side walls and a connecting wall connecting them, with a sealing material such as chloroprene rubber interposed therebetween. A protrusion for cutting off the insulating film on the surface of the side wall of the vertical frame is formed on the side edge of the conductive plate attached to the back surface of the connecting wall of the vertical frame, and a tap pin screw is used to remove the conductive plate. The plate body, vertical frame, sealing material, and horizontal frame are screwed together.

(Example) A sash frame joining device according to the present invention will be described below based on the drawings. Components common to those shown in FIGS. 1 and 2 are designated by the same reference numerals.

3 to 5, the present invention has a vertical frame 1 equipped with a pair of parallel side walls 1a, 1a and a connecting wall 1b connecting them, with a sealing material 2 such as chloroprene rubber as in the conventional example. horizontal frame 3
This device is used for a connecting device for sash frames in which vertical and horizontal frames 1 and 3 are screwed together, and when the vertical and horizontal frames 1 and 3 are screwed together, a conductive plate 7 such as an iron plate is screwed onto the back surface of the vertical frame connecting wall 1b. In other words, when the vertical and horizontal frames 1 and 3 are screwed together using the tuft pin screws 4, 4, the conductive plate 7 is screwed at the same time. In this example, the conductive plate 7 has protrusions 7a on both sides of the lower end.
7a is formed, and when the plate body 7 is attached to the vertical frame, the protrusions 7a, 7a are formed on the vertical frame side walls 1a, 1a.
The vertical frame 1 and the plate 7 are electrically connected by pressing against the inner surface of the side wall 1a to break the paint and oxide film applied to the side wall 1a.

Note that what has been described above applies to these protrusions 7a, 7
The distance between the ends a is the parallel side walls 1a, 1a of the vertical frame 1.
This means that the distance is set slightly larger than the distance between the two. Therefore, as another way of wearing it,
The conductive plate 7 is slightly tilted to form the parallel side walls 1a,
1a, and when screwing the conductive plate 7 to the vertical frame, the plate 7 is corrected so as to be parallel to the vertical frame connecting wall 1b, so that the protrusions 7a, 7
a comes into pressure contact with the inner surfaces of the vertical frame side walls 1a, 1a, and the paint and oxide film applied to the side walls 1a are broken,
In this way, the vertical frame 1 and the conductive plate 7 may be electrically connected. The current path when grounding the horizontal frame 3 (corresponding to the lower frame in this example) is explained with reference to Figs. 3 and 4. Sexual plate body 7 → plate body protrusion 7a
The A base metal of the vertical frame 1 shown by → the vertical frame 1 → the anchor 5 → the welding rod (not shown).

Note that the conductive plate 7 is attached to the vertical frame 1 in the sixth step.
As shown in the figure, the vertical frame 1 is attached to the back side of the vertical frame connecting wall 1b.
It goes without saying that the screw through holes 1c, 1c of the vertical frame 1 and the holes 7b, 7b of the conductive plate 7 are made to coincide with each other.
Furthermore, unlike the embodiment, the projection 7a of the conductive plate 7 is formed only on one side, and as shown in FIG.
The L-shaped protrusion 7a may be configured to clamp and press the vertical frame side wall 1a, in other words, the conductive plate 7 is screwed onto the back surface of the vertical frame connecting wall 1b. At this time, any form may be adopted as long as the protrusion 7a comes into pressure contact with the vertical frame side wall 1a.

(Effects of the invention) As is clear from the above explanation, the sash frame coupling device according to the present invention allows electricity to flow between the vertical and horizontal frames by simply attaching a conductive plate having a protrusion to the vertical frame. This ensures grounding not only during welding when assembling the sash, but also when using the building after construction.
Its practical advantages are enormous.
