Description

  The present invention relates to a smoke-proof hanging wall.

  2. Description of the Related Art Conventionally, in an office building, a shopping mall, or the like, a smoke-proof hanging wall is provided on the ceiling in order to form a smoke-proof section for each area defined by the Building Standard Law. The smoke-proof hanging wall is usually formed using a glass plate so as not to block the user's field of view (see, for example, Patent Document 1). However, there is a possibility that such a glass smoke-proof hanging wall may be broken and scattered due to an earthquake, and an improvement in safety has been demanded.

  Then, the smoke-proof hanging wall using the resin-made sheet | seat instead of a glass plate is proposed (for example, refer patent document 2). Such a smoke-proof hanging wall is generally configured to include a sheet mounting rail for holding the upper edge of the sheet and sheet end holders for holding both ends of the sheet, and the sheet end portions at both ends. By fixing the sheet in a state where tension is applied to the sheet by the holder, the sheet is stretched without wrinkles. According to such a sheet-made smoke-proof hanging wall, unlike a glass-made smoke-proof hanging wall, it does not break and scatter, so it is possible to constitute a highly safe smoke-proof hanging wall.

That is, first, screws are inserted into the two screw holes 31f provided in the rear shaft portion 31c of the rail shaft portion 31 from the two screw holes 33f provided in the base portion 33a of the fixed side holding portion 33. By stopping, the base portion 33a and the rail shaft portion 31 are connected. Subsequently, by inserting a screw from the screw hole 33g provided in the vicinity of the upper end portion of the protruding tip portion 33c into the screw hole 31e provided in the front shaft portion 31b of the rail shaft portion 31, and fixing the protruding tip. The portion 33c and the rail shaft portion 31 are connected. Thus, the fixed side holding part 33 can be stably attached to the rail shaft part 31 by attaching the fixed side holding part 33 so as to be sandwiched from the front and rear of the rail shaft part 31. As described above, the fixed side holding part 33 and the movable side holding part 34 are screwed to each other and temporarily connected. Further, the top plate portion 32 is placed on the upper surface of the rail shaft portion 31. Thus, the assembly of the rail shaft portion 31, the top plate portion 32, the fixed side holding portion 33, and the movable side holding portion 34 is completed, and the edge holding portion 30 having a substantially L shape in front view as shown in FIG. Can be configured integrally.

  And the edge part holding part 30 comprised in this way is made to contact | abut from the front with respect to the side of the rear rail 21, and the lower surface of the glass holder 7. FIG. At this time, another portion of the rail shaft portion 31 is brought into contact with the rear horizontal upper portion 22b while a portion of the rail shaft portion 31 is kept in contact with the lower surface of the top plate portion 32. In such a state, a screw is inserted and fixed through the outer screw hole 31d in the upper shaft portion 31a and the screw hole 32a in the top plate portion 32 sequentially, and the inner screw hole 31d in the upper shaft portion 31a. , And through the outermost screw hole 22e in the rear horizontal upper portion 22b in sequence, screws are inserted and fixed. In this manner, the edge holding part 30 having a substantially L shape in front view shown in FIG. 10 is attached to the lower surface of the ceiling 3 via the glass holder 7. In the state where the attachment is completed in this way, a gap with a constant interval (for example, several centimeters) is formed between the fixed-side protruding piece 33b of the fixed-side holding portion 33 and the wall portion. The edge holding part 30 (excluding the sheet holding part 35) in the vicinity of the right wall part 5 and the edge holding part 30 (excluding the sheet holding part 35) in the vicinity of the left wall part 6 are described above. The attachment can be performed in the same manner by the above method.

  Next, the seat 10 is temporarily fixed to the upper rail 20. Such temporary fixing is performed as follows. That is, first, the stoppers 11 are attached to the upper edge of the sheet 10 at a predetermined interval. Next, the front rail 26 is temporarily fixed from the front of the rear rail 21. Specifically, the front rail 26 is locked to the rear rail 21 by fitting the projection 28 of the front rail 26 into the groove 25 of the rear rail 21, and in this state, the front rail 26 is formed on the front vertical portion 27 a. The screw is inserted through the screw hole 27d thus formed and the screw hole 23a formed in the screw receiving portion 23 of the rear rail 21 in order to temporarily fix the screw. That is, in the temporary screwing at this time, the screws 10 are larger than the thickness of the seat 10 between the rear turn 22d of the rear rail 21 and the front turn 27c of the front rail 26 without completely tightening the screws. Tighten the screws to the extent that a gap smaller than the front and rear width is formed.

  Then, the seat 10 is slid from the side of the rear rail 21 and the front rail 26 between the rear fold 22d and the front fold 27c so that the stopper 11 is located inside the rear rail 21 and the front rail 26. By doing so, the seat 10 is arranged over the entire width of the rear rail 21 and the front rail 26. Here, since the retainer 11 is disposed above the rear turn 22d of the rear rail 21 and the front turn 27c of the front rail 26 in the seat 10, the retainer 11 moves the seat 10 downward. It is regulated and it is possible to prevent the sheet 10 from dropping downward.

  Thus, the temporary fixing of the seat 10 to the upper rail 20 is completed. In this state, the seat 10 is slidable along the width direction with respect to the upper rail 20, and the tension along the width direction is not yet applied to the seat 10. Further, a part of the inner side of the rail shaft portion 31 is accommodated inside the upper rail 20 (that is, inside the space formed between the rear rail 21 and the front rail 26). A part of the outer side is attached to the fixed side holding portion 33 and the top plate portion 32.

  Next, the left and right edge portions of the sheet 10 are attached to the movable side holding portion 34. Specifically, first, the edge of the seat 10 attached to the upper rail 20 is brought into contact with the front surface of the seat fixing portion 34c of the movable side holding portion 34, and the seat clamping portion 35 is further placed on the front surface of the seat 10. The sheet clamping portion 35 and the sheet fixing portion 34c are screwed at positions where the screw holes 36f formed in the sheet fixing portion 34c and the screw holes 35a formed in the sheet clamping portion 35 are in contact with each other. And fix. In this way, the sheet 10 can be firmly fixed by sandwiching and fixing the sheet 10 from the front and the back by the sheet holding part 35 and the sheet fixing part 34c. Note that the edge of the seat 10 near the left wall portion 6 and the edge of the right wall portion 5 in the vicinity can be similarly attached to the movable side holding portion 34 by the method described above.

  Next, tension is applied to the seat 10 by pulling the movable side holding portion 34 near the right wall portion 5 and the movable side holding portion 34 near the left wall portion 6 outward. Specifically, first, a screw for temporarily fixing the movable side holding portion 34 and the fixed side holding portion 33 is removed, and the movable side holding portion 34 is placed above the lower support portion 33 d of the fixed side holding portion 33. Put. And the space | interval between the fixed side protrusion piece 33b of the fixed side holding | maintenance part 33 and the movable side protrusion piece 34b of a movable side support part is adjusted. Although the specific method of this adjustment is arbitrary, in this Embodiment 1, using the well-known vise, the fixed side protrusion piece 33b of the fixed side holding part 33 and the movable side protrusion of the movable side support part. Adjustment is performed by narrowing the gap between the pieces 34b. In the first embodiment, first, the tension of the seat 10 is adjusted by pulling the movable side holding part 34 in the vicinity of the left wall part 6 outward, and then the movable side in the vicinity of the right wall part 5. Although the description will be made on the assumption that the tension of the sheet 10 is finely adjusted by pulling the holding portion 34 outward, the present invention is not limited to this, and the order may be reversed in the left and right directions, or may be performed simultaneously in the left and right directions.

  Next, the sheet 10 is fixed in a state where a predetermined tension is applied to the sheet 10 as described above. Specifically, first, in the state where tension is applied to the seat 10 using a vise as described above, the screw hole 36a for main fixing in the base connecting portion 34a in the base portion 33a of the fixing side holding portion 33, Holes are drilled at positions corresponding to 36c and 36e using a drill or the like. Then, by moving the screws through the holes of the base portion 33a formed by the drill or the like from the screw holes 36a, 36c, 36e for permanent fixing in the base connection portion 34a and fixing them, The side holding part 34 is fixed to the fixed side holding part 33. Note that the movable side holding portion 34 may be fixed to the fixed side holding portion 33 by any method, not limited to the method using such a drill, for example, a tapping screw or a drill screw without using a drill. Etc. may be fixed by inserting the screw holes 36a, 36c, 36e through the base portion 33a.

  Next, the rear rail 21 and the front rail 26 are permanently fixed by completely tightening the screws of the rear rail 21 and the front rail 26 that have been temporarily fixed as described above. As a result, the upper edge of the seat 10 can be clamped by the rear turn 22d of the rear rail 21 and the front turn 27c of the front rail 26, and the upper portion of the seat 10 can be fixed.

  Next, the cover 40 is attached to the movable side holding part 34 and the fixed side holding part 33. Specifically, first, the rivet is inserted through the rivet hole 41g formed in the left exterior part 41c of the front cover 41 and the rivet hole 42e formed in the cover connection part 42c of the rear cover 42, and then riveted. Thus, the front cover 41 and the rear cover 42 are connected to each other. Then, in a state where the blocking member 44 is in contact with the recess 47 of the left exterior part 41 c of the front cover 41, the closure member 44 is sandwiched between the recess 47 of the left exterior part 41 c and the closure member fixing part 45. The member 44 is fixed to the closing member fixing portion 45 by rivets. Further, the bottom claw portion 43a of the lower cover 43 is attached, the rivet is inserted from the rivet hole 41f formed in the front cover 41 to the rivet hole 43c formed in the bottom claw portion 43a, and the rear cover 42 is formed. The rivet is inserted from the rivet hole 42d through the rivet hole 43d formed in the bottom claw portion 43a, and these are riveted. Further, the bottom exterior part 43b is brought into contact with the bottom claw part 43a attached in this manner, and rivets are inserted from the rivet hole 43g of the bottom exterior part 43b to the rivet hole 43f of the bottom claw part 43a, and these are inserted. Secure with rivets.

  Thus, in the state where the front cover 41, the rear cover 42, the lower cover 43, the closing member 44, and the closing member fixing portion 45 are integrally connected, these integrated members are connected to the movable side holding portion 34 and the fixed side holding portion 33. And is slid upward until the upper end portions of these integral members come into contact with the top plate portion 32. At this time, these integral members are slid so as to pass the sheet 10 through a gap between the right front exterior part 41 b of the front cover 41 and the right rear exterior part 42 b of the rear cover 42.

  Then, the screw hole 41d formed in the front exterior portion 41a of the front cover 41 and the screw hole 33h formed in the protruding tip portion 33c of the fixed side holding portion 33 are sequentially inserted and fixed, The screw hole 46 a provided in the long hole cover 46, the screw hole 41 e formed in the front exterior part 41 a of the front cover 41, and the screw hole 33 i formed in the protruding tip part 33 c of the fixed side holding part 33 are sequentially passed through. These integral members can be attached to the fixed-side holding portion 33 by inserting and fixing screws. At this time, since the tension of the sheet 10 is applied to the fixed-side holding portion 33, the screw hole 33i may be located inside the position before the sheet 10 is attached. Since 41e is formed as a long hole, the screw can be inserted from the screw hole 41e to the screw hole 33i regardless of the movement of the position of the screw hole 33i. Further, since the long hole cover 46 is interposed in front of the long hole in this way, it is possible to improve the design by closing the long hole.

  Thus, since the smoke-proof hanging wall 1 can be constructed without fixing the fixed side holding part 33 and the movable side holding part 34 to the column part, it is possible to improve the proof stress during an earthquake or the like. In addition, it is possible to reduce the labor and cost of fixing the aggregate to the wall. In addition, each of the above-described operations can be performed from one direction (front in the first embodiment), and the workability can be improved.

(Effect of Embodiment 1)
Thus, according to the first embodiment, since the sheet 10 is fixed without attaching the edge holding portion 30 to the wall portion, it is possible to prevent interference between the edge holding means and the wall portion. It is possible to prevent breakage and dropping of the part holding part 30 and the upper rail 20 at the time of an earthquake and to improve the proof stress, and to take the trouble of forming an aggregate for fixing the edge holding part 30 to the wall part. It can be omitted and the workability can be improved.

  In addition, since at least one of the edge holding portions 30 is arranged so as not to contact the wall portion arranged farther from the sheet 10 than the edge holding portion 30, the edge holding portion 30 is attached to the wall portion. Interference can be further prevented, and the proof strength of the edge holding portion 30 and the upper edge holding means during an earthquake can be further improved.

  Moreover, since the closing member 44 for closing the gap between the edge holding part 30 and the wall part is provided, smoke can be prevented from moving through the gap, and the edge holding part 30 and the wall part can be prevented. It is possible to improve the smoke-proof performance while preventing interference.

  Further, since the upper edge holding means is fixed to the ceiling 3 via the glass holder 7 which is a constituent member of the existing glass smoke-proof hanging wall, the upper rail 20 is attached to the ceiling 3 without removing the glass holder 7. It is possible to replace the glass smoke proof wall with the sheet smoke proof wall 1 very easily.

  Moreover, since the space | interval between the fixed side holding | maintenance part 33 and the movable side holding | maintenance part 34 can be adjusted very easily by adjusting the space | interval of the fixed side protrusion piece 33b and the movable side protrusion piece 34b, workability | operativity Can be further improved.

  Further, since the retainer 11 and the rear turn 22d and the front turn 27c are provided, the sheet 10 can be prevented from falling off by an extremely easy method, and workability can be improved.

  Moreover, since the sheet | seat 10 is formed from a nonflammable glass fiber material, combustion of the sheet | seat 10 can be prevented and smoke-proof performance can be improved.
