DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass setting block mounting structure in which a glass setting block is installed in a swallowing groove of a horizontal member so as not to move in the longitudinal direction.

[0002]

2. Description of the Related Art The setting position of a setting block for supporting a glass with a swallowing groove of a horizontal member located below the glass, such as a blind frame of a shoji screen or a blind wall of a curtain wall, is determined by the width of the glass. The distance a from the edge of the glass is set to a size such that the glass can be safely supported at two points as shown in FIG. 3. There is a danger of breaking the glass because the reaction force is concentrated.

[0003] Since the glass is repeatedly displaced in the in-plane horizontal direction with respect to the cross member within the depth of the swallow groove of both vertical frames during an earthquake, the setting block is slid in the swallow groove at the same time. The conventional setting block is attached to the bottom of the swallow groove with a simple means such as adhesive or adhesive tape, or on the base of a groove-shaped cross section installed in the swallow groove as shown in Japanese Utility Model Publication No. 55-48932. Since the setting block is only placed or glued, the setting block is easily dragged by the glass during the earthquake and is easily insulated from the bottom of the swallowing groove, and the setting block may slide out of the appropriate range as shown in FIG. There is.

The present invention proposes a setting block mounting structure that does not move even in the event of an earthquake from the above background.

[0005]

According to the present invention, a base having a restraining portion for supporting a setting block and restraining the lengthwise movement thereof is fixed in the swallowing groove, and the setting block is fixed to the restraining portion of the base. By mounting on a base with movement restricted to both sides in the direction, movement of the setting block due to displacement of the glass during an earthquake is prevented, and a situation in which the glass is damaged is avoided.

[0006] Since the setting block is restrained by the base and the base is fixed to the swallowing groove, the setting block maintains the state restrained by the base even when the glass is displaced with respect to the cross member during an earthquake. As long as the fixed state of the base is not released, the setting block does not move and keeps the state of supporting the glass safely even after the earthquake, so that the glass is not broken.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a setting block 4 for supporting a glass 3 to be swallowed in a swallowing groove 2 of a horizontal member 1 is installed in the swallowing groove 2 so as not to move. The cross member 1 includes a blind frame of the illustrated curtain wall and a lower frame of a shoji constituting various windows.

As shown in FIG. 2, a base 5 which supports a setting block 4 in a swallowing groove 2 and has a restraining portion 51 for restraining the lengthwise movement thereof is fixed. Base 5
The restricting portion 51 engages or locks the setting block 4 in any direction in the longitudinal direction to restrict the movement to both sides in the longitudinal direction.

The base 5 only needs to be fixed in the swallowing groove 2 so as not to move together when the glass 3 is displaced with respect to the cross member 1, and penetrates the base 5 itself to form the swallowing groove 2 as shown in the figure. It is fixed by the screw 6 screwed into the bottom 21 or any other part. Alternatively, it is fixed by a simple fixing means such as fitting or engaging with any part of the swallowing groove 2, or also partially welding. A space is secured between the lower surface of the base 5 and the bottom surface 21 of the swallow groove 2 so as not to hinder drainage of rainwater that has entered the swallow groove 2. The space is secured by projecting the legs 52 on the lower surface of the base 5.

The setting block 4 is a rubber molded product, and the base 5 is made of metal such as an extruded aluminum material.
A rising piece having a piece bent toward the setting block 4 is formed on the upper surface of the piece, and a section of the setting block 4 of the bent piece is cut off to leave both sides thereof, so that both end positions in the length direction of the setting block 4 are provided. Are formed with restraining portions 51, 51 which engage with the end surfaces thereof. Since the restraining portion 51 only has to restrain the movement of the setting block 4 to both sides in the longitudinal direction, the similar restraining portion 51 is formed at one or a plurality of locations in the middle of the setting block 4 in the longitudinal direction. On the other hand, the movement of the setting block 4 can also be prevented by forming a groove in which the restricting portion 51 enters into the setting block 4 and fitting the restricting portion 51 into the groove. The shape of the restraining portion 51 is not limited to the plate shape as illustrated.

In the case of the embodiment, the setting block 4
The base 5 is placed on the base 5 while being sandwiched between the two restraining portions 51, 51. When the glass 3 is to be displaced with respect to the cross member 2 during an earthquake, the setting block 4 remains at the original position by the base 5, so that only the glass 3 slides along the setting block 4 to cause a displacement.

[0012]

According to the present invention, the base having the restraining portion for supporting the setting block and restraining the longitudinal movement thereof is fixed in the swallowing groove, and the setting block is restrained by the restraining portion of the base from moving in both longitudinal directions. The glass is broken when placed on the base, preventing the setting block from moving due to the displacement of the glass during an earthquake, maintaining the state of supporting the glass safely even after the earthquake. Can be avoided.
