Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a seismic isolation glass smoke proof wall.

[0002]

[Prior art]

 Conventionally, buildings with a floor area larger than the specified floor area according to the Building Standards Law are obliged to provide hanging walls from the ceiling to provide smoke-proof hanging walls to prevent the movement of smoke in the event of a fire. I have.

[0003] However, when an earthquake or the like also occurs in this glass smoke-proof hanging wall, only the glass at both ends of the glass hanging wall continuously constructed between the walls often breaks or breaks in many cases. Can be seen.

On the other hand, there is a seismic wall glass receiver which receives only the weight of the glass as a metal fitting and is directly attached with a differential rubber, as shown in FIGS. 4, 5 (a) and 5 (b). As shown, it has the following disadvantages. In case of severe shaking, the glass receiving bracket is an integral type with hanging bolts from the ceiling rail, so the glass is easily separated from the rubber and separates from the rubber, which is extremely dangerous. In the case of in-plane interlayer displacement and out-of-plane interlayer displacement in response to shaking, it is difficult to restore to the original state, so this is not seismic isolation, but merely earthquake resistant. There is absurdity for maintenance. In other words, since it is hung at one point from the ceiling rail, it often shakes and is unstable during work such as glass screening, and the glass is easily broken. At the time of construction, it is difficult to work because glass is attached and the bell becomes bellows and the rubber twist is added. The rubber material is general rubber, which burns and emits smoke in the event of a fire.

[0005]

[Problem to be solved by the present invention] Therefore, the present invention has a configuration capable of restoring the original state to the in-plane interlayer displacement and the out-of-plane interlayer displacement, and the construction work and the maintenance work are easy. In addition, the aim is to develop a non-flammable glass smokeproof wall.

[0006]

[Means for Solving the Problems]

 In order to achieve the above objectives, an aluminum wall receiver is installed between the wall and the glass, and the assembly (see drawing) uses a threaded plate (A) and a concealed nut (B) to attach the suspension bolt ( C) to develop a seismic isolation glass wall with a seismic isolation structure that absorbs in-plane and out-of-plane displacements and displacements stepwise and elastically, prevents glass breakage, and is easy to restore to its original state. Things.

[0007]

[Embodiment of the invention]

 An embodiment of the present invention will now be described with reference to the drawings. Referring to the drawings, a ceiling rail (X) is installed on a ceiling surface (V), and a plurality of glasses (G) are sequentially connected and hung from the ceiling rail. A smoke-proof hanging wall; having an opening (1a) near one end surface (referring to a wall, a pillar, or the like) of the smoke-proof hanging wall for inserting a glass serving as a hanging wall on one side, facing the opening; A closed-wall surface (1b) is formed on the surface, a wall-shaped glass receiver (1) having a U-shaped cross section and a closed bottom surface (1c); a suspension rail (C) hanging from the ceiling rail; The end of the glass (G) is inserted into the opening (1a) of the wall glass receiver (1), and the closed surface (1b) of the wall glass receiver (1) and the smoke-proof hanging wall are inserted. A gap (Z) with the end surface (Y) is made of an elastic material such as rubber, and a semicircular or convex shape is formed on the end surface. A seismic isolation glass shield characterized in that a differential adjusting member (2) having a bulging portion (2a) is fixed to a wall glass receiver (1) and slidably contacts the end face with the differential adjusting member (2). It is composed of smoke walls.

[0008] A hole (1d) is formed in the bottom surface (1c) of the wall glass receiver (1) into which a hidden nut (B) is inserted, and a ceiling rail in which a threaded plate (A) is inserted is formed in the hole. It is fastened and fixed with a concealed nut (B), which is suspended from the (X) and is fastened to a suspension bolt (C), to set the wall glass receiver (1) to the ceiling rail.

Further, the differential adjusting member (2) may be hollow with the bottom (2b) closed, the material may be a flame-retardant material, and the ceiling rail (X) The method of attaching is a conventional method, and is not particularly limited.

Then, one side of the glass (G) is inserted into the opening (1a) and the bottom surface (1c) of the wall glass receiver (1), and the upper surface is inserted into the ceiling rail (X), and sealed with a sealing material (W). The adjacent glass is received by the continuous glass receiver (3) and provided sequentially.

[0011]

[Effect of the invention]

 According to this invention, a differential adjustment member made of an elastic material such as rubber is provided between the wall surface glass receiver and the end surface of the installation start or end portion of the smoke proof slidable wall so as to be slidable with the end surface. Because of the beam, it has an effect on the in-plane (inter-layer displacement) and out-of-plane (inter-layer displacement), and has extremely beneficial effects such as a resilient seismic isolation effect.
