Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a face material supporting frame formed on the outside of a building, and a frame material for locking the top and bottom side inner surfaces of the side surface, the left and right side inner surfaces of the room, or the four-side inner surface The present invention relates to a so-called SSG type curtain wall surface member disengagement prevention structure which is configured by locking a locking frame material adhesive surface material formed by adhering to each other by the locking frame material.

[0002]

2. Description of the Related Art Conventionally, for example, a locking frame material adhesive glass formed by bonding a locking frame material to the outer surface of a lattice-shaped glass support frame having a cubic shape and a blind side is attached to the inner surface of the inner circumference of the glass. SS with a beautiful appearance that locks with a frame material and leaves only thin joints between adjacent glass and does not expose the cubic and blind eyes to the outer surface.
Although a G-type curtain wall has been proposed, when the adhesive that bonds the locking frame material to the glass deteriorates, there is a risk that the glass will come off the glass support frame and fall onto the road.

As a safety measure to prevent this, glass fitting grooves are provided on both upper and lower surfaces of the glass supporting frame, and the upper and lower ends of the glass are fitted into the fitting grooves to remove the glass when the adhesive deteriorates. A retaining structure for stopping is known.

[0004]

However, in the above-described conventional glass detachment prevention structure, the seamless appearance is exposed between the vertically adjacent glasses, and the appearance is improved even though the locking frame material adhesive glass is used. It has resulted in a loss. An object of the present invention is to sufficiently prevent the detachment of the face material when the adhesive is deteriorated while maintaining a beautiful appearance only by leaving thin joints between the adjacent face materials.

[0005]

As a means for solving the above problems, the present invention provides a plurality of locking frame material adhesive face materials on the outdoor side surface of a face material support frame formed on the outside surface of a building. In the adjacent portions of the face materials adjacent to each other in the SSG type curtain wall in which the locking frame members are locked so as to be attached to each other in the adjoining state, the two adjacent end faces of the adjacent face materials are opposed to each other. An expansion surface is formed so that the distance from the indoor end portion to the outdoor side portion is wider than the indoor end portion distance, and a locking flange having a width corresponding to the expansion surface distance between the face material adjacent end surfaces. A retaining member having a portion at one end abuts the locking flange portion on the expanded surface of the end face adjacent to the face material and passes the other end between the end faces adjacent to the face material to the indoor side, and the face material support frame. The surface material removal prevention structure for the SSG curtain wall attached to To draft.

The face material removal preventing structure according to the present invention is provided only in the left and right vertical girder adjacent portions of face materials adjacent to each other.
It may be provided only on the adjacent portions of the upper and lower horizontal lines, or may be provided on the adjacent portions of the left and right vertical vertical lines and the upper and lower horizontal lines.

Further, the "expansion surface" includes an inclined expansion surface which is inclined and spread from the indoor side end portion in a groove shape, a stepwise expansion surface which is gradually expanded from the indoor side end portion, and various other types. Includes a flared surface.

The "face material" in the present invention includes glass, stone material, concrete, ceramic material, wood, metal,
It includes synthetic resins and various other materials. Embodiments of the present invention will be described below with reference to the drawings.
