Description

  TECHNICAL FIELD The present invention relates to the technical field of a waterproof device in a building opening / closing device installed in an opening that communicates outdoors, such as a doorway to a building or an underground doorway, and a maintenance method for the waterproof device.

Today, there is known a device for opening and closing an opening of a building, which is opened and closed by raising and lowering the opening and closing body by being guided by the left and right guide rails provided in the opening of the building. It has been attempted to take measures against rain so that water such as rainwater does not enter from the outside when an opening / closing device is provided in an opening that communicates outdoors. As a measure against such rain, it has been put into practical use to raise the outdoor floor surface of the opening to a higher level so that rainwater does not enter the inside. However, in such a case, there is a problem that the raised floor portion on the outdoor side becomes a stepped portion, which obstructs entrance and exit.
Therefore, while providing waterproof seals made of rubber elastic material on the left and right side surfaces and the bottom surface of the opening / closing body, the floor seals contacting the waterproof seal and the inner side surfaces of the left and right frame bodies contact the waterproof seals when the opening / closing body is closed. There is known a structure in which a pressing body for waterproofing is provided by crushing the waterproof seal so that the waterproofing function can be exhibited (see, for example, Patent Document 1).
However, while this one is provided with a waterproof seal on the front surface of the opening / closing body, it is also provided with a pressing body that exposes the frame side by pressing and deforming the waterproof seal when the door is closed. However, there is a problem in that the external appearance is impaired due to the above.

First, the first embodiment shown in FIGS. 1 to 11 will be described. In the drawings, reference numeral 1 denotes a shutter curtain (opening / closing body) of a heavy-duty shutter device for a building. The shutter curtain 1 is formed by connecting slat 1a in series in the vertical direction by interlock coupling and has an upper end edge. It is connected to a winding drum 2 provided on the ceiling. The shutter curtain 1 is configured to move up and down by being guided by guide rails 4 provided on the left and right sides of the opening as the winding drum 2 rotates based on forward and reverse driving of the electric opening / closing device 3. All of the above are the same as before.

  Reference numeral 5 denotes a waterproof panel (waterproof plate). The waterproof panel 5 includes a single plate-shaped panel body 6 and a groove-shaped end cover 7 that is detachably attached to both left and right ends of the panel body 6. The panel main body 6 is dimensioned such that the width of the panel body 6 is fitted in the guide grooves 4a of the left and right guide rails 4 and the thickness of the panel is loosely fitted in the guide rails 4. An angle member 6a is attached to the upper end surface of the panel body 6, and a slat 1b at the lowermost end of the shutter curtain 1 (which does not have a lower interlock joint) 1b is a bolt 6b which is an example of a tightening tool. Is fixed through.

The end cover 7 is provided with a front / rear plate 7a, a left / right outer plate 7b, and a bottom plate 7c, and is configured in a groove shape that is open upward in the vertical direction and inward in the horizontal direction. The dimensions are set so that the guide rail 4 is loosely fitted and the panel main body 6 is externally fitted. In particular, the front and back plates 7a prevent the end cover 7 from being displaced in the front-rear direction with respect to the panel body. As a result, the end cover 7 is not displaced by water pressure but is displaced by water pressure. It can be externally fitted to the panel body 6 in a state where there is no
Airtight seals (e.g., rubber elastic material such as EPDM) 7d are attached to the inner surfaces of the outer surface plate 7b and the bottom surface plate 7c over the entire surface. The airtight seals 7d are formed on the left and right ends of the panel body 6. When the end cover 7 is fitted into the outer surface plate 7b and the bottom surface plate 7c so as to be pressed against it, the end cover 7 is crushed and exhibits airtightness. In this state, the inner edge 7i of the front and back plate 7a is dimensioned to extend inward in the left-right direction from the guide groove 4a of the guide rail 4 and has an extension 7h. Then, the extending portion 7h is detachably fixed to the panel body 6 via a screw 7e which is an example of a tightening tool, but in the present embodiment, when the panel body 6 is thin, The upper and lower positions are set so that the screw parts of the screws 7e screwed in from the front and back sides do not come into contact with each other.
Further, the left-right inner edge 7j of the end cover bottom plate 7c protrudes inward in the left-right direction longer than the inner edge 7i of the extending portion 7h of the front and back plate 7a, thereby forming a protrusion 7f. The end cover 7 is configured to come into contact with the bottom plate 6c of the panel body 6 in a state where the airtight seal 7d is sandwiched between the bottom cover 6c and the front and back plates 7a so as to project inward in the left-right direction. As a result, as will be described later, the work of attaching / detaching the end cover 7 to / from the panel body 6 is designed so that the protrusion 7f can be gripped, whereby the amount of extension of the extension 7h from the guide rail 4 can be increased. Is reduced so that the fixing portion of the end cover 7 by the screw 7e is brought close to the guide rail 4 and the appearance is impaired.
Further, the angle member 6a of the panel body 6 is formed with notches 6d at both left and right ends, and the notches 6d interfere with a steady rest (not shown) provided on the lowermost slat 1b. Is to avoid.

Reference numerals 8 and 8a denote a seal body and a seal end portion which form the waterproof seal S, and the seal body 8 is attached to the bottom plate 6c of the panel body 6 by, for example, a double-sided adhesive tape, and the seal end portion 8a. Is also affixed from the outer surface of the end cover outer surface plate 7b to the inner end edge 7j of the bottom surface (that is, the outer peripheral surface) of the bottom surface plate 7c through the outer surface of the corner portion 7g. 8, the seal end portion 8a is made of, for example, a low-repulsion rubber elastic material, but the seal main body 8 and the facing portion 8b facing each other at the edge portions of the protruding portion 7f of the seal end portion 8a are made of an adhesive. It is glued and integrated so that there are no gaps. Since the seal body 8 has a structure that closes the abutting portions of the bottom surface plate 6c of the panel body 6 from the front and rear sides, it also contributes to waterproofing inside the panel body 6.
The seal end portion 8a is attached so as to be bent at a corner portion 7g between the outer surface plate 7b and the bottom surface plate 7c of the end cover 7 and is integrated, but the outer periphery of the corner portion 8c of the seal end portion 8a. Since the waterproof seal S is thick in the height direction, the surface has an arc-shaped structure even when bent at the corner 7g.

A pressing tool 9 is attached to the groove bottom surface 4b of the guide rail 4. The pressing tool 9 is formed by screwing a screw 9a which is an example of a tightening tool into the groove bottom surface 4b into a vertically long mounting hole 9l. It is composed of a fixed substrate 9b and a pressing body 9c protruding inward in the left-right direction from the substrate 9b, but the substrate 9b is narrower than the guide groove 4a and the existing guide groove 4a. Can be retrofitted to.
The pressing body 9c is inclined such that the amount of protrusion inward in the left-right direction increases from the upper end to the lower side, and reaches the intermediate position in the up-down direction of the substrate 9b, and the first pressing portion 9d. The second pressing portion 9e reaching the vicinity of the floor surface F while maintaining the protruding amount of the lower end, the lower end is in contact with the floor surface F, and the left and right inner edge (that is, the top side) 9m of the pressing body 9c is the lower end side. It is formed by a third pressing portion 9f which reaches the floor surface F by being inclined so as to become gradually lower through the corner portion 9j which is arcuate so as to project inward in the left-right direction. The left and right inner ends 9g of the 9f protrude inward in the left and right direction from the left and right outer end edges 6e of the waterproof panel 5.
Incidentally, the left-right inner end 9g of the third pressing portion 9f is processed so that there is no step with respect to the floor surface F, so that the left-right inner end 9g of the seal end portion 8a comes into contact with the pressing portion. It is set so that there is no gap in.
It should be noted that the pressing tool 9 of the present embodiment has a fitting hole 9h formed in a flat plate-shaped substrate 9b as shown in FIG. 7, and the projection formed on the pressing body 9c in the fitting hole 9h. It is formed by fitting 9i and welding both.
Further, as the shape of the inner end 9g in the left-right direction of the pressing body 9c, for example, as shown in FIG. 7D, various shapes such as a square shape (preferably a chamfered corner portion), an arc shape, a mountain shape, etc. Can be in the shape of.

Then, when the shutter curtain 1 is closed, the left and right side surface portions 8d attached to the outer surface plate 7b of the end cover 7 are sequentially brought into contact with the first pressing portion 9d from below to be deformed by pressing. . When the left and right side surface parts 8d reach the second pressing portion 9e, the left and right side surface parts 8d are pressed with the deepest deformation amount, and finally, the seal body 8 provided on the bottom plate 6c of the panel body 6 is pushed. Also, the bottom side portion 8e provided on the bottom plate 7c of the end cover 7 comes into contact with the floor surface F and is crushed and deformed, whereby the bottom portion and the left and right end portions of the waterproof panel 5 are waterproofed. ing.
In this case, the corner portion 8c in which the outer peripheral surface of the seal end portion 8a has an arc shape is pressed by the corner portion 9j of the pressing body 9c which is also formed in an arc shape (the curvatures may be the same or different). Therefore, for example, when the corner portion 9j has an obtuse corner shape having an angle connecting the top sides of the second pressing portion 9e and the third pressing portion 9f, the sealing end portion 8a at the obtuse corner portion is formed. It is set so as to avoid the possibility that the pressure deformation at the arc-shaped corner portion 8c becomes insufficient and water leaks easily. It is variously selected according to, and it is not always necessary to form an arc.
As a measure for preventing water leakage at the corner portion 9j of the pressing body 9c, the corner portion 9j is limited to an arc shape (having a large curvature) larger than the arc of the corner portion 8c of the seal end portion 8a. Alternatively, for example, a small arc shape may be used as shown in FIG. 10 (A), and as shown in FIG. 10 (B), the corner portion 9j may be divided into the second pressing portion 9e and the third pressing portion 9f. The top piece is left obtusely intersecting, and a linear fourth pressing portion 9k is provided between the second pressing portion 9e and the third pressing portion 9f as shown in FIG. In this way, the obtuse angle of the corner portion can be increased, and this can be consulted to avoid water leakage. As shown in FIG. 7D, the two corners 9j where the top sides intersect are arcuate, and the fourth pressing part 9k is further polygonal. You can also do it.

When the opening and closing of the shutter curtain 1 is repeated in this manner, the outer surface of the seal end portion 8a provided on the lateral outer surface plate 7b of the end cover 7 slides on the first to third pressing portions 9d, 9e, 9f. The pressing deformation is repeated in a moving state and is consumed, and in such a case, maintenance is required to replace the seal end portion 8a.
As a maintenance method in this case, a step of removing the screw 7e of the extension 7h, a step of extracting the end cover 7 from the panel body 6, a step of extracting the end cover 7 from the guide rail 4, and a step of providing the end cover 7 are provided. The step of replacing the seal end 8a, the step of fitting the end cover 7 with the seal end 8a replaced into the guide rail, the step of replacing the end cover 7 with the seal end 8a at the extension 7h The step of fixing the screw 7e to the step 7 is sequentially performed. Specifically, for example, the shutter curtain 1 is raised to a position where the lower end edge of the waterproof panel 5 does not at least come into contact with the first pressing portion 9d, and in this state While cutting the facing portion (bonding portion) 8b between the seal body 8 and the seal end portion 8a, the screw 7e for fixing the end cover 7 to the panel body 6 at the extending portion 7h is removed. And the end cover 7 can be detached from the panel body 6, and the detached end cover 7 is moved downward and pulled out from the guide rail 4, whereby the pulled out end cover 7 becomes a single body. The seal end 8a can be replaced with. Then, the end cover 7 whose seal end 8a has been replaced can be incorporated into the panel body 6 in the reverse order.
This procedure is effective when the bottom plate protruding portion 7f is fixed to the bottom plate 6c of the panel body 6 with the screw 7e, and the screw 7e fixed to the bottom plate 6c is fixed to the seal end 8a. It is possible to remove the bottom side portion 8e from the bottom plate projecting portion 7f to expose the screw 7e and then remove the screw 7e.

Furthermore, as another specific maintenance method, with the shutter curtain 1 in the fully closed position (or a position close to the fully closed position), the screw 7e is removed from the extending portion 7h, and then the shutter curtain is raised. The end cover 7 is pulled out from the panel body 6. After that, the end cover 7 is pulled out from the guide rail 4, the seal end 8a of the pulled out end cover 7 is replaced, and the end cover 7 having the seal end 8a replaced is replaced by a panel in the reverse order. It may be attached to the main body 6.
This procedure is effective when the bottom plate protruding portion 7f is attached to the bottom plate 6c of the panel body 6 with, for example, a double-sided adhesive tape, and in this case, the screw 7e is removed at the extending portion 7h. After that, when raising the shutter curtain, the end cover 7 can be removed from the panel body 6 by peeling off the bottom plate protrusion 7f attached to the bottom plate 6c.

At the left and right ends of the angle member 6a provided at the upper end of the panel body 6, left and right steady rests 10 for preventing the waterproof panel 5 from swinging left and right are provided. The steady rest 10 is composed of a plate-shaped support member 10a and a roller 10b mounted outside the support member 10a in the left-right direction. The support member 10a has a long hole 10d extending in the left-right direction. By this, the left and right mounting positions can be adjusted by the bolt (tightening tool) 10c with respect to the angle member 6a of the steady rest 10, and the roller 10b has a slight gap (for example, 2 mm) from the guide rail groove bottom surface 4b. The waterproof panel 5 is prevented from being displaced in the left-right direction, so that the pressing deformation of the seal end portion 8a by the pressing body 9c is made uniform left and right as much as possible. In this case, the steady rest 10 needs to be attached so as to be accurately positioned. Therefore, in the present embodiment, as shown in FIG. 9, a bolt 10c and a fixing screw (fastener) 10e are used. After the steady rest 10 is accurately positioned, it is securely fixed by the fixing screw 10e.
Further, in this structure, the L-shaped reinforcing metal fittings 12 are fixed to the indoor side through the bolts 12a in the panel body 6, but the reinforcing metal fittings 12 are provided only on the outdoor side and on both the indoor and outdoor sides. Good. Further, since the reinforcing metal fitting 12 is provided at the lower end portion of the waterproof panel 5, it is advantageous in strength.
Furthermore, an inverted L-shaped auxiliary metal fitting 13 is provided at an upper corner portion on the outer side in the left-right direction of the panel body 6, and the auxiliary metal fitting 13 serves as a guide when the end cover 7 is attached to the panel body 6. As a result, the workability of maintenance work is improved.

  In the present embodiment configured as described above, the shutter curtain 1 opens and closes the opening by vertically moving the guide rails 4 provided at both left and right ends of the opening. At the lower end, a waterproof panel 5 is provided, the left and right ends of which are fitted into the guide rail 4 and guided up and down. The waterproof panel 5 is detachably fixed to the panel body 6 with both left and right ends thereof fitted in the guide rails 4, and in a state where the waterproof panel 5 is detachably fitted into the left and right ends of the panel body 6. The waterproof seal S for waterproofing the lower part of the opening is configured by including a groove-shaped end cover 7 and a seal body 8 attached to the bottom plate 6c of the panel body 6 and the end cover 7. It is configured to include a seal end portion 8a provided on the outer peripheral surfaces of the lateral outer surface plate 7b and the bottom plate 7c, and when the shutter curtain 1 is in the closed posture, the seal body 8 and the bottom side portion 8e of the seal end portion 8a. Is brought into contact with the floor surface F and crushed to exert a waterproof function, and the left and right side surface portions 8d and the corner portions 8c of the seal end portion 8a are pressed and deformed by the contact of the pressing body 9c provided in the guide rail 4. Waterproof machine There is exhibited, it is possible to ensure this by high waterproofness.

  Since the pressing body 9c is provided inside the guide rail 4 in this structure, the appearance is not impaired, but the corner portion 8c of the seal end portion 8a and the left and right side surface portions 8d are in contact with the pressing body 9c in a sliding contact. Since the contact is repeated every time the shutter curtain 1 is opened and closed, the consumption is quick, and if left unattended, the waterproof property is impaired. Therefore, maintenance is required to replace the seal end 8a.

  In order to perform this maintenance, while the waterproof panel 5 is positioned at least at the upper end of the pressing tool 9, the facing portion 8b where the seal body 8 and the seal end portion 8a are adhered to each other is cut, and the guide rail is also used. 4, the end cover 7 comes off from the panel body 6 when the screw 7e is removed at the extending portion 7h that extends inward in the left-right direction and is exposed on the front surface of the waterproof panel 5 for easy work. Then, the end cover 7 is pulled out from the panel body 6 and pulled out from the guide rail 4 in a state of being lowered. As a result, the seal end 8a can be replaced with only the end cover 7 taken out, and then the end cover 7 provided with the newly replaced seal end 8a can be attached to the panel body 6 by the reverse operation. You can

  In the embodiment of the present invention as described above, the seal end portion 8a and the pressing body 9c are provided inside the guide rail 4 so as not to be seen from the outside, but the maintenance for replacing the seal end portion 8a is performed. The work can be easily performed without removing the waterproof panel 5 from the guide rail 4.

  In addition, in this structure, the seal end portions 8a attached to the lateral outer surface plate 7b and the bottom surface plate 7c of the end cover 7 are provided as an integrated body by bending the corner portions 8c, so that the corner portions 8c are formed. The seal end portion 8a can be easily replaced as compared with a case where the seal end portion 8a is provided as a separate object with the boundary as a boundary.

In addition, the bottom surface plate 7c of the end cover 7 is provided with a protruding portion 7f that is stacked below the bottom surface plate 6c of the panel body 6 so as to protrude further inward in the left-right direction than the extending portion 7h. Therefore, the end cover 7 grasps the projecting portion 7f and can insert and remove the end cover 7 from the panel body 6, and as a result, the extension portion 7h fixed via the screw 7e is extended. The amount of protrusion can be made as small as possible, and the deterioration of the appearance of the waterproof panel 5 can be reduced.
Further, since the seal end portion 8a and the facing portion 8b of the seal body 8 which face each other are bonded and waterproofed, it is possible to prevent water from leaking from here.

Further, an airtight seal 7d for ensuring airtightness between the end cover 7 and the panel body 6 including the corner portion 7g is provided on the inner surfaces of the outer surface plate 7b in the left-right direction and the bottom plate 7c of the end cover 7. The waterproof panel 5, which is a barrel, is divided into the end cover 7 and the panel body 6 for easy maintenance, but the airtightness can be secured.
In addition, in this structure, the angle member 6a provided in the panel body 6 is provided with the steady rest 10 for restraining the waterproof panel 5 in the left-right direction. As a result, the seal end portion 8a is slightly displaced from the pressing body 9c in the left-right direction, and the seal end portion 8a is uniformly pressed and deformed to improve waterproofness.

  Of course, the present invention is not limited to the above-mentioned embodiment, and like the embodiment shown in FIG. 11, the groove width of the guide rail 4 is wide and the waterproof panel 5 is positioned in the front-rear direction. When there is a possibility that the seal end portion 8a is displaced and the pressing deformation of the seal end portion 8a is biased, the front and rear direction outer surfaces of the front and rear plates 7a of the end portion cover 7 are used to prevent the waterproof panel 5 from swinging in the front and rear direction. The front-and-rear direction steady rest 11 can be provided, whereby the left and right uniform seal end portions 8a are pressed and deformed, and the waterproof property is improved.

Furthermore, the second embodiment after FIG. 12 will be described. Since the shutter curtain 1 is wider in the left-right direction than that of the first embodiment, it receives a higher water pressure, and the front-back thickness of the waterproof panel 21 is adjusted to withstand this. The guide rail 4 is thicker than the groove width of the guide rail 4 within the inner dimension.
Since the waterproof panel 21 is wide and thick in the left and right, the weight is heavy, and it becomes difficult to assemble it into the left and right guide rails 4 when it is used as a single item, and it requires a large amount of transportation to the site, so that it is configured as a split type. There is. The number of divisions is not particularly limited, but is preferably an odd number. The reason is that when the number of the odd-numbered sheets is set, there is no dividing position in the central portion of the waterproof panel 21 in the left-right direction, and the water pressure resistance is improved. In the following second embodiment, a waterproof panel 21 divided into three parts will be described.

  The waterproof panel 21 is composed of the panel body 22 and the end cover 7 as in the case of the first embodiment. The panel body 22 is configured by using a center panel (connecting panel) 24 and a pair of left and right symmetrical end panels 25. The center panel 24 and the left and right end panels 25 have the same left and right lengths. However, the left and right end lengths of the central panel 24 and the left and right end panels 25 may be different from each other. The center panel 24 may have the same length as each other, but the center panel 24 may have a different length (the length may be longer or shorter) from the end panel 25, or one end panel 25 and the center panel 24 may have the same length. The other end panel 25 may have the same length but different lengths. Furthermore, the waterproof panel for giving strength may be a two-part split type having only the both end panels 25 without the connecting panel 24. In this case, the connecting portion between the end panels 25 is a waterproof panel. The strength can be increased by shifting the position in either the left-right direction instead of the center position in the left-right direction. In this case, it goes without saying that the connecting portion of either one of the end panels 25 has the structure of the first connecting portion 24d of the first embodiment.

The central panel 24 includes a central panel body 24a having a thick box shape, and inverted L-shaped first and second angle members 24b and 24c fixed to an upper end surface of the central panel body 24a. The center panel body 24a is provided with first connecting portions 24d provided at both left and right ends.
The horizontal pieces of the first and second angle members 24b and 24c are welded to the upper surface of the central panel body 24a in a state where the vertical pieces are butted back to back. In the present embodiment, the outdoor-side first angle member 24b matches the left-right length of the central panel body 24a, but the second angle member 24c has both end edges longer than the left-right length of the central panel body 24a. There is.
Further, the first connecting portion 24d is formed as an extending portion 24k that extends the front and back plates 24j of the central panel body 24a outward in the left-right direction in the present embodiment, but the left and right end surfaces of the central panel body 24a are formed. In addition, for example, it may be configured by welding a bridging portion of a U-shaped member. And in this thing, the lower end edge of 24 d of 1st connection parts is the notch part 24f notched by the board thickness of the bottom plate 24e.

The end panel 25 includes a box-shaped thick end panel body 25a, and inverted L-shaped third and fourth angle members 25b and 25c fixed to the upper surface of the end panel body 25a. The second connecting portion 25d fixed to the inner side in the left-right direction of the panel body 25a, and the second connection portion 25d protruding from the outer surface 25i in the left-right direction of the end panel body 25 so as to be fitted into the guide groove 4a of the guide rail 4 in a loose fit manner. The guided portion 25e is provided.
The horizontal pieces of the third and fourth angle members 25b and 25c are welded to the upper surface of the end panel body 25a in a state where the vertical pieces are butted against each other. In the present embodiment, the third angle member 25b on the outdoor side matches the left-right length of the end panel body 25a, but the fourth angle member 25c is equal to the length of both end edges of the second angle member 24c. The length is shorter than the left-right length of the end panel body 25a.
The second connecting portion 25d has a U-shaped first connection in which the leg portion 25h is welded to the front and back surface plate 25g in a state where the straddle portion 25f extends inward in the left and right direction with respect to the front and back surface plate 25g of the end panel body 25a. The metal fitting 25i and the leg portion 25j fitted in the first connecting metal fitting 25i are welded to the leg portion 25h of the first connecting metal fitting 25i. The extended portion 24k of the extended first connecting portion 24d is externally fitted to the extended portion of the leg portion 25h of the first connecting metal fitting 25i via the bolt (tightening tool) 22a. The center panel 24 and the end panel 25 can be connected by fixing the parts. After the connection, the abutting surface portion is caulked with iron putty, and then the surface of the panel body 22 is waterproof coated.

Then, the waterproof panel 21 of the present embodiment is assembled as follows. First, the left and right end panel bodies 25a are arranged on the floor surface F so that the guided portions 25e fit into the guide rails 4. Next, the central panel body 24a is lifted up, and the first connecting portion 24d is lowered onto the second connecting portion 25d in a male-female externally fitted state, and placed on the floor surface F. Then, the panel main body 22 can be assembled by fixing the first and second connecting portions 24d and 25d to each other via the bolt 22a. After that, the first to fourth angle members 24b, 24c, 25b, 25c are fixed to the lowermost slat 1b via the bolts 22b, whereby the waterproof panel 21 of the present embodiment can be assembled. It has become.
The male-female fitting structure of the first and second connecting portions 24d, 25d may of course be reversed. A caulking material is applied in advance to the surface contact portions of the connecting portions 24d and 25d to improve the waterproof performance.
In this case, the end cover 7 provided with the seal end 8a having the same structure as that used in the first embodiment may be attached to the guided portion 25e in advance, but the panel body 22 may be attached to the shutter curtain. The end cover 7 may be attached in a lifted state after attaching the end cover 7. The seal main body 8 can be attached to the bottom plates 24e and 25g by lifting it from the floor surface F after the panel main body 22 is connected to the shutter curtain 1. However, the seal main body 8 is previously attached in a state of being divided into the bottom plates 24e and 25g. You can leave it. When the seal main body 8 is of a split type, it is taken care not to impair the waterproof property by bonding the ends of the seal main body 8 to each other after the panel main body 22 is assembled and then the opposite ends are bonded with an adhesive. It
In the present embodiment, the seal body 8 attached to the bottom surface of the panel body 22 is arranged so as to be continuous with the seal end 8a attached to the end cover 7 as in the first embodiment. In addition to the one to be attached, another seal main body 8 is attached so as to be juxtaposed to the outdoor side, but this may be provided on the indoor side or further provided inside and outside.
Incidentally, since the end cover 7 has the same structure as that of the above-mentioned embodiment, its details are omitted.
Further, L-shaped reinforcing metal fittings 26 are fixed to the front and back surfaces of the panel body 22 assembled in this way via bolts 26a. The reinforcing metal fitting in the present embodiment is divided into two parts in the central portion in the left-right direction, and by configuring in this way, the dividing position of the reinforcing metal fitting 26 and the dividing position of the panel body 22 are misaligned. It is designed to increase strength. In this case, it is preferable to provide the reinforcing metal fitting 26 at a lower position of the panel body 22 in order to secure strength. Incidentally, the reinforcing metal fitting 26 may of course be a single piece instead of the split type.

  In this structure, the second angle member 24c provided on the central panel 24 is long and has a structure overlapping with the third angle member 25b of the end panel 25, and the overlapping portion is fixed with the bolts 22b. It is possible to increase the strength even in.

  Regarding the arrangement of such angle members, it goes without saying that the panel main bodies 24a and 25a may abut each other at the divided portions, but for example, the protruding side may be the fourth angle member 25c on the end panel 25 side. The abutting positions of the materials can be largely deviated from each other, such as the middle position of the end panel 25 in the left-right direction or the middle position of the center panel 24 in the left-right direction. By doing so, the abutting position of the angle members largely deviates. As a result, it will be displaced from the connection position of the panel bodies, and the strength can be further increased. When the fourth angle member 25c is lengthened, the procedure for assembling the waterproof panel 22 is as follows: the central panel 24 is set, the end panel 25 is lifted, and the guided portion 25e is fitted inside the guide rail 4. After the end panels 25 are set down on the left and right sides of the central panel 24, the first and second connecting portions 24d and 25d are connected to each other, so that the panel body 22 can be assembled.

Also in this case, when the seal end 8a is worn out, only the end cover 7 is removed from the panel main body 22 to replace the seal end 8a, and then the end is re-started as in the first embodiment. By attaching the cover 7, replacement maintenance work can be easily performed.
In each of the above embodiments, the shutter curtain 1 is provided with a waterproof panel at the lower end of the electric type, but a manual type in which the waterproof panel alone is installed on the guide rail without providing the shutter curtain. Needless to say,
