Description

  The present invention relates to a smoke barrier wall. Specifically, it relates to a smoke barrier that temporarily blocks the flow of smoke generated during a fire or the like.

Conventionally, what was described in patent document 1, for example is known as this kind of smoke-proof hanging wall.
Specifically, as shown in FIG. 8, the upper rail 102 of the glass smoke-proof hanging wall 101 connected to the ceiling light ceiling member is about 50 to 100 mm away from the wall or pillar. Stopped in position.

  Here, in order to suppress secondary disasters caused by glass breakage or damage during an earthquake, a calcium plate 103 for the purpose of absorbing deformation following impact is inserted between a wall and a pillar, and an end portion of the calcium plate 103 is fitted. The non-combustible sheet-made seismic isolation wall stand 104 is attached.

Utility Model Registration No. 3172946

  However, in the invention described in Patent Document 1, the stress of shaking during an earthquake is absorbed by deformation of the calcium plate, but if the deformation is large, the calcium plate is broken and dropped.

  Therefore, at the time of restoration, it is necessary to attach a new calcium-based board or a non-combustible sheet-made seismic isolation wall stand, which takes time and effort for restoration.

  Further, since the calcium silicate board is colored white, the contrast with the smoke-proof wall made of glass is large, and the appearance is poor.

  The present invention was devised in view of the above points, and it is an object of the present invention to provide a smoke proof wall capable of preventing damage and falling of a smoke proof plate due to shake during an earthquake. is there.

  In order to achieve the above object, a smoke-proof hanging wall to which the present invention is applied includes a mounting rail disposed on a ceiling surface, and a glass smoke-proofing whose upper end is attached to the mounting rail and suspended. A plate, and an end pressing portion that is arranged on both sides of the smoke proof plate and is configured to be able to contact and flex along the end of the smoke proof plate.

  Here, a plurality of smoke-proof plates can be suspended from the ceiling surface in a row by the mounting rail disposed on the ceiling surface.

  Moreover, it becomes possible to temporarily block the flow of smoke generated at the time of a fire or the like by the glass smokeproof plate suspended at its upper end attached to the mounting rail. Furthermore, since only the upper end is attached, it becomes possible to follow a swing in a direction perpendicular to the smoke proof plate due to an earthquake or the like.

  In addition, it is arranged on both sides of the smoke proof plate, and in contact with the end of the smoke proof plate, and is configured to be flexible so that it can be flexed, for example, to both sides of the smoke proof plate due to an earthquake. The end pressing portion can be flexed in response to the shaking. As a result, it is possible to prevent the smokeproof plate from falling or damaged.

  In addition, in the case of a non-flammable semi-cylindrical portion in which the end pressing portion is configured in a substantially semi-cylindrical shape and the top portion is configured to be contactable along the end of the smoke-proof plate, for example, an earthquake The end presser portion configured in a substantially semi-cylindrical shape can be flexible against the shaking of the smoke proof plate in both directions. As a result, the smoke proof plate does not undergo surface deformation, and it is possible to prevent the smoke proof plate from falling or damaged. Furthermore, it is possible to prevent combustion in a fire by making it nonflammable.

  In addition, when the column arranged on both sides of the smoke proof plate or the wall surface is provided with a certain interval, and the lower end of the semi-cylindrical portion has a locking piece configured to be locked By locking the lower end of the semi-cylindrical portion, the smoke proof plate can be flexed against shaking in both directions and swaying in both directions of the smoke proof plate.

  Further, when the semi-cylindrical portion is formed by bending, only one bending process is required, and the manufacturing process can be largely omitted.

  In addition, when the semi-cylindrical portion is formed of a stainless material, it has non-flammability against fire and impact resistance against earthquakes, and the appearance is improved with the gloss unique to the stainless material.

  Further, when the locking piece is made of an aluminum material, it has non-flammability against fire and is lightweight, so that it can be easily attached to a pillar or a wall surface.

  In addition, when the smoke proof plate is made of a transparent material, the ceiling surface is partitioned by the transparent smoke proof plate, so that, for example, the aesthetics or lighting in the store is not impaired.

  The smoke proof wall according to the present invention can prevent the smoke proof plate from being damaged and dropped due to shaking during an earthquake.

  Here, for example, the smoke-proof plate 3 suspended from the mounting rail 2 on the ceiling A surface along the top portion 23 of the semi-cylindrical portion 22 of the end pressing portion 20 on the prism-shaped or round-column-shaped column portion 19 surface. It arrange | positions so that the edge part 26 may contact | abut (refer FIG. 6 (A) and FIG. 7 (A)).

  Thus, the smoke-proof board 3 arrange | positioned on the ceiling A surface between the column-shaped column parts 19 of a prismatic shape or a round column shape, for example, when the vibration to the column-part 19 direction (C arrow in a figure) by an earthquake arises The semi-cylindrical portion 22 is flexible or the contact state between the end portion 26 and the top portion 23 is released, thereby suppressing the deformation of the smoke-proof plate 3 (FIG. 6B and FIG. 7). (See (B)).

  Further, for example, when a shake in the direction of arrow D in the figure due to an earthquake occurs, the deformation of the smoke proof plate 3 is suppressed by the semi-cylindrical portion 22 being flexible.

  Note that, even when shaking in the direction C in the drawing and the direction D in the drawing occurs at the same time or in other directions, the semi-cylindrical portion 22 is flexible or the end portion 26 is the same as described above. The state of contact with the top 23 is released, so that the deformation of the smoke proof plate 3 can be suppressed.

  In the smoke proof wall of the present invention having the above configuration, it is possible to suppress the deformation of the smoke proof plate due to shaking and prevent the smoke proof plate from being damaged or dropped.

  Further, the end pressing portion is formed of a non-combustible member made of stainless steel or aluminum so that it does not burn off in the event of a fire. As a result, it is possible to prevent a fall disaster and achieve the purpose of preventing smoke movement.

  Further, the end pressing portion can be configured by, for example, bending a stainless steel plate into a semicylindrical shape. Therefore, the production efficiency is improved by simplifying the manufacturing process.

  Further, the end pressing portion is formed in a semi-cylindrical shape so that it can be attached even if the attachment location is a curved surface such as a round columnar column portion.

  Furthermore, since the cross section is semicircular, it absorbs by flexing the stress caused by shaking from each direction at the time of earthquake and suppresses the deformation of the smoke barrier.

  In addition, since it becomes possible to use a transparent glass plate for the smoke-proof plate on the end side of the smoke-proof hanging wall, it is possible to take sufficient light-transmitting space between the wall surfaces or between the column portions. Become.
