2. Description of the Related Art Generally, in a panel shutter of this type, a plurality of panel bodies are connected in series through a connecting member such as a connecting chain, a connecting wire, a connecting belt, etc. Configured to be transformed into a closed posture in which the opening and closing guide rails are lowered in series to close the opening portion, and a storage posture in which the ceiling storage portion is stored in parallel with the interior storage guide rails. There is.
By the way, recently, there is a demand for fireproof and smokeproof properties, sound insulation properties, etc. in such a panel shutter, and it is necessary to add some airtight function there. In this case, if the panel body has a flat plate shape, a sealing member for sealing the space between the panel body and the magsa in a fully closed state may be provided. Since it is formed of a single plate-shaped material, it is impossible to measure the daylighting and the like, and it is not possible to provide a material that is rich in design changes. On the other hand, there is a structure in which a frame member that surrounds at least four circumferences and a thin plate member that is fitted into a space surrounded by the frame member are used in order to provide lighting to the panel body.

[0003]

However, when a panel body using such a thin plate material is used, irregularities are formed on the panel body itself, and it is practically difficult to seal it with a sealing member. is there. Therefore, it has been proposed that the pitch (vertical width) of the panel body is set so that the frame member is just opposite to the magsa in the fully closed state, and that the gap between the magsa and the frame member is sealed. It But with this one,
Set the total pitch of the panel body according to the height of the frontage of the opening, or use the panel body facing the magsa when fully closed, with the panel pitch changed so that the frame material faces the magsa, etc. Need consideration. However, at the time of factory production, it is preferable that the panel pitch is as constant as possible from the viewpoint of productivity, etc.In addition, what is actually delivered to the construction site is a frame material with dimensions in the fully closed state. It is good if it faces Magsa, but there is no such guarantee, and there is often a position shift due to dimensional differences or design changes on the frame side.In such a case, a frame material or thin plate material should be used. There was a problem to be solved by the present invention, because it was forced to adjust the pitch by cutting on the spot.

Since it is set to be framed by fitting 3, the thickness A of the horizontal frame member 12 is approximately the plate thickness on the front and back sides (inside and outside directions) than the thickness B of the vertical frame member 11 and the middle frame member 13. The vertical frame member 11 is fitted in the guide groove 7a of the opening / closing guide rail 7 at least on the front side surface which is fitted in the guide groove 7a of the vertical frame member 11. A spacer 14 for sealing is fixed to the portion so as to be substantially flush with the horizontal frame member 12.

By the way, each of the frame members 11, 12 and 13 is formed by extruding a member made of aluminum or the like, or bending a band-shaped steel plate by roll forming or the like. The peripheral edges of the thin plate member 10 are fitted and fixed to the recessed grooves 11a, 12a, 13a formed in the reference numerals 12, 13 via a seal member 15, respectively.
As a result, the panel body 2 includes the frame members 11, 12, 13
The panel surface has a step-like uneven surface in the front-back direction between the portion and the thin plate member 10. In this structure, the top panel body 2 is set such that the thin plate material 10 portion faces the indoor and outdoor magsa 16 which is the entrance / exit portion of the shutter curtain 1 of the ceiling side storage portion 5 in a state where the shutter curtain 1 is fully closed. The contact member 17 according to the present invention is provided on the front and back surfaces of the portion of the thin plate member 10 facing the magsa to ensure airtightness.

That is, the abutting member 17 is provided over substantially the entire length in the left-right direction, but is bent in a substantially U-shaped cross section and has a pair of upper and lower leg portions 17a and an abutting surface portion 17.
b is formed, and the abutting surface portion 17b is dimensioned so as to be substantially flush with the front and back surfaces of the horizontal frame member 12 when attached as described later. Further, the tip end portion of the lower leg portion 17a is bent upward, and the bent portion 17c is set to contact the plate surface of the thin plate member 10 via the sealing material 15. The lower leg portion 17a serves as the sealing surface portion of the present invention, and sealing is performed between the abutting surface portion 17b and the thin plate member 10. Here, the abutting member 17 is divided and installed between the adjacent vertical frame members 11 and the intermediate frame members 13. In that case, the notch is formed in the leg portion 17a at a position facing the vertical frame members 11 and the intermediate frame members 13. Then, screw both ends of the butting surface 17b into the screw 1
The vertical frame member 11 and the middle frame member 13 are fixedly attached by 7d to be integrally attached. By the way, vertical frame 1
1 and the middle frame member 13 are back plate members 11b and 1b which also serve as ridges for detachably exchanging the thin plate member 10 from the indoor side.
3b is designed to be attachable to and detachable from the frame body via the screws 11c and 13c. When the backing member 17 is fixed to the vertical frame member 11 and the middle frame member 13, the backing plate members 11b and 13b are fixed to the backing plate members 11b and 13b with screws 17d. When the thin plate member 10 is replaced in the uppermost panel body 2, the backing members 11b and 13b are removed after removing the pad member 17 from the vertical frame member 11 and the middle frame member 13 one by one.
There is an advantage that the backing members 17b and 13b can also be removed by removing the backing plate members 11b and 13b without removing the backing members 11b and 13b. Limited). Furthermore, the end edge of the abutting surface portion 17b attached to the vertical frame member 11 of the abutting member 17 is dimensioned so as to abut against the spacer 14.

On the other hand, of the indoor and outdoor magsa 16, on the upper surface of the outdoor magsa 14, a base end portion of a sealing member 18 formed in a tongue shape with a non-combustible sheet material such as glass fiber cloth. Is fastened via a screw 18a, the tip of the sealing member 18 is in contact with an abutting surface 17b provided on the front surface side (outside of the room) of the panel material 10, and the magsa on the outside of the room. The gap between 16 and the abutting surface portion 17b is sealed, so that the magsa 16 portion is hermetically sealed.

In the embodiment of the present invention constructed as described above, the panel body 2 constituting the shutter curtain 1
Causes the opening to move up and down based on forward and reverse driving of the sprocket 6. In this case, the magsa 16 is provided on the front and back surfaces of the thin plate member 10 of the panel body 2 when the shutter curtain 1 is fully closed. Abutting surface portion 17b of the abutting member 17

Sealed between 7b. Further, the butting surface portion 17
The space between b and the thin plate member 10 is sealed by the lower leg portion 17a formed on the pad member 17, and the magsa 16 portion on the outdoor side is sealed to ensure an airtight structure. . Incidentally, the airtightness between the opening of the guide groove 7a of the opening / closing guide rail 7 and the vertical frame member 11 is as follows.
A spacer 14 is provided on the vertical frame member 11, which seals a portion communicating with the inside and outside of the shutter curtain 1 when the shutter curtain 1 is fully closed, thereby preventing fire and smoke inside and outside the room, and sound insulation.

As described above, the panel body 2 includes the frame members 11, 1
Although the thin plate material 10 is fitted into the panels 2 and 13 and the concave-convex portion is formed on the panel surface, when the cover member 17 and the sealing member 18 are fully closed, the airtight structure in the magsa 16 portion is maintained. Since it can be ensured, it is possible to form a panel shutter using a thin plate material such as a glass plate capable of daylighting and having fireproof and smokeproof properties while being excellent in design. Further, since the airtight structure is made by attaching the contact member 17 to the thin plate member 10 facing the magsa 16, the panel pitch is adjusted according to the height of the frontage of the opening at each construction site as in the conventional case. There is no need for the horizontal frame to face the magsa 16 by changing or changing the top panel body, and it is possible to factory-produce a panel body with a fixed pitch as a standard product, which will reduce costs. be able to. In addition, if there is a design change or an assembly error at the construction site, it is sufficient to mount the contact member 17 on the site so as to face the magsa 16, which facilitates the site work and improves workability.

By the way, if the contact member 17 is provided on one side surface of the thin plate member 9, it is possible to impart performance such as fire prevention and smoke prevention. The thin plate member 10 is reinforced by the contact member 17 by being provided on both front and back surfaces of the thin plate member 10.

The present invention is not limited to the above-mentioned embodiment, and the contact member is provided on one side surface of the thin plate material, and the side is provided on the sealing member and each panel vertical frame member. It may be sealed by means of, and even in this case, it has a function of fireproofing and smokeproofing inside and outside, but in particular, it is structurally effective to make the outside of the room airtight.
Further, the sealing member is provided only on the outside of the room, but may be provided both on the inside and outside of the room. Further, the sealing member may of course be provided not on the magsa but on the contact member side.
