First, those shown in FIGS. 1 to 11 show reference examples, which will be described first. In the drawing, reference numeral 1 denotes a shutter curtain (opening / closing body) of a heavy-duty shutter device for construction, and the shutter curtain 1 is formed by connecting slats 1a in a series in the vertical direction by an interlock coupling, and has an upper end edge. It is connected to a take-up drum 2 provided on the ceiling. The shutter curtain 1 is adapted to move up and down by being guided by guide rails 4 provided on the left and right sides of the opening by rotating the take-up drum 2 based on the forward and reverse drive of the electric switch 3. Everything is the same as before.

Reference numeral 5 denotes a waterproof panel (waterproof plate), wherein the waterproof panel 5 includes a single plate-shaped panel main body 6 and a groove-shaped end cover 7 that can be freely inserted and removed from both left and right ends of the panel main body 6. The panel main body 6 is configured such that the left and right widths are fitted into the guide grooves 4a of the left and right guide rails 4, and the panel thickness is loosely fitted into the guide rails 4. An angle member 6a is attached to the upper end surface of the panel body 6, and the lowermost slat (without the lower interlock joint) 1b of the shutter curtain 1 is attached to the angle member 6a as an example of a tightening tool. It is fixed via.

The end cover 7 includes a front and back plate 7a, a left and right outer plate 7b, and a bottom plate 7c, and is formed in a groove shape with openings in the upper and lower directions and inward in the left and right directions. , The dimensions are set so that they are loosely fitted to the guide rail 4 and externally fitted to the panel body 6.
An airtight seal (for example, a rubber elastic material such as EPDM) 7d is attached to the inner surfaces of the outer surface plate 7b and the bottom plate 7c over the entire surface, and the airtight seal 7d covers the left and right ends of the panel body 6. When the end cover 7 is fitted inward so as to be pressed against the outer surface plate 7b and the bottom plate 7c, it becomes a crushed state and exhibits airtightness. In this state, the inner end edge 7i of the front and back plates 7a is sized so as to extend inward in the left-right direction from the guide groove 4a of the guide rail 4, and the extending portion 7h is formed. Then, the extending portion 7h is detachably fixed to the panel main body 6 via a screw 7e which is an example of a tightening tool. However, in the present embodiment, when the panel main body 6 is thin, The vertical position is set so that the screw portions of the screws 7e screwed from the front and back sides do not come into contact with each other.
Further, the left-right inner end edge 7j of the end cover bottom plate 7c protrudes inward in the left-right direction longer than the inner end edge 7i of the extending portion 7h of the front-back plate 7a, whereby the protruding portion 7f is formed. The end cover 7 comes into contact with the bottom plate 6c of the panel main body 6 in a state where the airtight seal 7d is sandwiched between them, with the protruding portion 7f projecting inward in the left-right direction from the front and back plates 7a. As a result, as will be described later, the work of attaching and detaching the end cover 7 to and from the panel body 6 is taken into consideration so that the protruding portion 7f can be gripped, whereby the amount of extension of the extending portion 7h from the guide rail 4 is taken into consideration. Is made smaller so that the fixing portion of the end cover 7 by the screw 7e is brought close to the guide rail 4 to reduce the deterioration of the appearance.
Further, the angle member 6a of the panel body 6 has notches 6d formed at both left and right ends, and the notches 6d interfere with a steady rest body (not shown) provided at the lowermost end slat 1b. It is for avoiding.

Reference numerals 8 and 8a are a seal body and a seal end portion constituting 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 attached in a state of extending 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 plate 7c through the outer surface of the corner portion 7g. 8. The seal end 8a is constructed using, for example, a low-resilience rubber elastic material, but the sealing body 8 and the opposite portion 8b facing each other at the end edge portion of the protruding portion 7f of the seal end 8a are made of an adhesive. They are glued together so that there are no gaps. Since the seal body 8 has a structure that closes the abutting portion of the bottom plate 6c of the panel body 6 from the front and back, it also contributes to waterproofing inside the panel body 6.
The seal end portion 8a is attached and integrated so as to be bent at the corner portion 7g of the outer surface plate 7b and the bottom plate 7c of the end cover 7, but the outer circumference of the corner portion 8c of the seal end portion 8a is integrated. Since the waterproof seal S is thick in the height direction, the surface has a structure that is curved in an arc shape even when it is bent at the corner portion 7 g.

Reference numeral 9 denotes a pressing tool 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 a vertically long mounting hole 9l into the groove bottom surface 4b. It is composed of a substrate 9b to be fixed 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 It can be retrofitted to.
The pressing body 9c is inclined so that the amount of protrusion inward in the left-right direction increases from the upper end to the lower side, and the first pressing portion 9d reaches the intermediate position in the vertical 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 protrusion amount of the lower end, the lower end is in contact with the floor surface F, and the inner edge (that is, the top) 9 m in the left-right direction of the pressing body 9c is on the lower end side. It is formed by a third pressing portion 9f which is inclined so as to gradually decrease through a corner portion 9j which is arcuate in a state of protruding inward in the left-right direction and reaches the floor surface F. In 9f, the inner edge 9g in the left-right direction protrudes inward in the left-right direction from the outer edge 6e in the left-right direction 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 is in contact with the portion in a pressing shape. It is set so that there is no gap in.
As shown in FIG. 7, the pressing tool 9 of this reference example has a fitting hole 9h formed in a flat plate-shaped substrate 9b, and a protrusion 9i formed in the pressing body 9c is formed in the fitting hole 9h. Is fitted and formed by welding the two.
Further, as the shape of the inner end 9g of the pressing body 9c in the left-right direction, for example, as shown in FIG. 7D, there are various shapes such as a square shape (preferably the corner portion is chamfered), an arc shape, and a mountain shape. Can be in the shape of.

Then, as the shutter curtain 1 closes, the left and right side surface portions 8d attached to the outer surface plate 7b of the end cover 7 are sequentially abutted from the lower side to the first pressing portion 9d and are pressed and deformed. .. When the left and right side surface portions 8d reach the second pressing portion 9e, the left and right side surface portions 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 provided. And the bottom side portion 8e provided on the bottom plate 7c of the end cover 7 abuts on the floor surface F and is crushed and deformed, whereby the bottom portion of the waterproof panel 5 and the left and right end portions are waterproofed. ing.
In this case, the corner portion 8c having an arc-shaped outer peripheral surface of the seal end portion 8a is pressed by the corner portion 9j of the pressing body 9c also formed in an arc shape (the curvature may be the same or different). Therefore, for example, when the corner portion 9j has an obtuse angle corner shape having an angle connecting the apex of the second pressing portion 9e and the third pressing portion 9f, the seal end portion 8a at the obtuse angle 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 leakage is likely to occur, but these are the hardness of the waterproof seal S, etc. It is not always necessary to make it arcuate because it is selected in various ways.
As a measure to prevent water leakage at the corner portion 9j of the pressing body 9c, the corner portion 9j is limited to an arc shape (large curvature) larger than the arc of the corner portion 8c of the seal end portion 8a. However, for example, it may have a small arc shape as shown in FIG. 10 (A), and further, as shown in FIG. 10 (B), the corner portion 9j is formed by the second pressing portion 9e and the third pressing portion 9f. A fourth pressing portion 9k is provided between the second pressing portion 9e and the third pressing portion 9f as shown in FIG. 3C, in which the top pieces are left at an obtuse angle. In this way, the obtuse angle of the corner can be increased, and it can be advised to avoid water leakage. In this case, as shown in FIG. 3D, the two corner portions 9j where the top edges intersect are formed into an arc shape, and the fourth pressing portion 9k is further formed into a polygonal shape of two or more. You can also do it.

When the shutter curtain 1 is repeatedly opened and closed in this way, 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, and 9f. Pressing deformation is repeated in the moving state, resulting in wear. In such a case, maintenance for replacing the seal end portion 8a is required.
Maintenance methods in this case include a step of removing the screw 7e of the extending portion 7h, a step of pulling out the end cover 7 from the panel body 6, a step of pulling out the end cover 7 from the guide rail 4, and a step of pulling out the end cover 7. The process of replacing the seal end 8a, the process of fitting the end cover 7 with the replaced seal end 8a into the guide rail, and the process of fitting the end cover 7 with the replaced seal end 8a into the extension 7h of the panel body 6 The steps of fixing the screws 7e to the seal 7e are 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 abut on at least the first pressing portion 9d, and in this state. When the opposite portion (adhesion portion) 8b between the seal body 8 and the seal end portion 8a is cut and the screw 7e for fixing the end cover 7 to the panel body 6 at the extension portion 7h is removed, the end cover 7 is removed. It can be removed from the panel body 6, and the removed end cover 7 is moved downward and pulled out from the guide rail 4, thereby replacing the seal end 8a with the pulled out end cover 7 as a single unit. Can be done. Then, the end cover 7 in which the seal end 8a has been replaced can be incorporated into the panel body 6 in the reverse procedure.
This procedure is effective when the bottom plate protruding portion 7f is fixed to the bottom plate 6c of the panel body 6 by the screw 7e, and the screw 7e fixed to the bottom plate 6c is the seal end portion 8a. The bottom side portion 8e can be peeled off from the bottom plate protruding portion 7f so that the screw 7e is exposed, and then removed.

Furthermore, as another specific maintenance method, the shutter curtain 1 is in a fully closed posture (or a posture close to fully closed), 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 is replaced in the pulled out end cover 7, and the end cover 7 in which the seal end 8a is replaced is displayed on the panel in the reverse procedure. 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. In this case, the screw 7e is removed from 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 protruding portion 7f attached to the bottom plate 6c.

Left and right steady rests 10 for preventing the waterproof panel 5 from swinging left and right are provided at both left and right ends of the angle member 6a provided at the upper end of the panel body 6. The steady rest body 10 is composed of a plate-shaped support member 10a and a roller 10b attached to the lateral side of the support member 10a. The support member 10a has an elongated hole 10d long in the left-right direction. Is formed, so that the left and right mounting positions can be adjusted with bolts (tightening tools) 10c with respect to the angle member 6a of the steady rest body 10, and the roller 10b has a slight gap (for example, 2 mm) from the bottom surface 4b of the guide rail groove. The waterproof panel 5 is configured to face each other so as to prevent the waterproof panel 5 from being displaced from side to side, so that the pressing deformation of the sealing end portion 8a by the pressing body 9c is made as uniform as possible to the left and right. In this case, the steady rest body 10 needs to be attached so as to be accurately positioned. Therefore, in the present embodiment, as shown in FIG. 9, the bolt 10c and the fixing screw (tightening tool) 10e are used. After the steady rest body 10 is accurately positioned, it is firmly fixed with the fixing screw 10e.
Further, in this case, an L-shaped reinforcing metal fitting 12 is fixed to the panel main body 6 via a bolt 12a on the indoor side, but the reinforcing metal fitting 12 is provided only on the outdoor side and on both the indoor and outdoor sides. May be good. Further, since the reinforcing metal fitting 12 is provided at the lower end portion of the waterproof panel 5, it is advantageous in terms of strength.
Furthermore, an inverted L-shaped auxiliary metal fitting 13 is provided at the upper corner portion on the outer side in the left-right direction of the panel main body 6, and the auxiliary metal fitting 13 serves as a guide when attaching the end cover 7 to the panel main body 6. It will function and the workability of maintenance work will be improved.

In this reference example configured as described above, the shutter curtain 1 opens and closes the opening by moving the guide rails 4 provided at the left and right ends of the opening up and down, and the lower end of the shutter curtain 1 is opened and closed. The portion is provided with a waterproof panel 5 in which both left and right ends are fitted inside the guide rail 4 to guide the vehicle up and down. The waterproof panel 5 is detachably fixed to the panel main body 6 in which the left and right end portions are internally fitted into the guide rail 4 and the left and right end portions of the panel main body 6 are detachably fitted to the left and right end portions. The waterproof seal S, which is configured to include a groove-shaped end cover 7 for waterproofing the lower portion of the opening, is a seal body 8 attached to the bottom plate 6c of the panel body 6 and the end cover 7. The outer surface plate 7b in the left-right direction and the seal end portion 8a provided on the outer peripheral surface of the bottom plate 7c are provided, 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 are provided. Is in contact with the floor surface F and is crushed to exhibit a waterproof function, and the left and right side surface portions 8d and the corner portion 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. A waterproof function is exhibited, which can ensure high waterproofness.

In this case, since the pressing body 9c is provided in the guide rail 4, 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. The contact is repeated every time the shutter curtain 1 is opened and closed, and the shutter curtain 1 is consumed quickly. If the shutter curtain 1 is left unattended, the waterproof property is impaired. Therefore, maintenance for replacing the seal end portion 8a is required.

To perform this maintenance, with the waterproof panel 5 located at least at the upper end of the pressing tool 9, cut the facing portion 8b where the seal body 8 and the seal end 8a are adhered, and guide rails. If the screw 7e is removed at the extension portion 7h that extends inward in the left-right direction from 4 and is exposed in front of the waterproof panel 5 and is easy to work with, the end cover 7 will come off from the panel body 6. Therefore, 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 removed, and then the end cover 7 provided with the newly replaced seal end 8a is assembled to the panel body 6 in the reverse operation. Can be done.

As described above, in this reference example, the seal end 8a and the pressing body 9c are provided in the guide rail 4 so that they cannot be seen from the outside, but the maintenance work for replacing the seal end 8a is performed. , The waterproof panel 5 can be easily done without removing it from the guide rail 4.

Moreover, in this case, the outer surface plate 7b in the left-right direction of the end cover 7 and the seal end portion 8a attached to the bottom plate 7c are provided as an integral body by bending the corner portion 8c, so that the corner portion 8c The replacement work of the seal end portion 8a becomes easier as compared with the case where the seal end portion 8a is provided as a separate object.

Further, the bottom plate 7c of the end cover 7 is provided with a protruding portion 7f which is laminated on the bottom plate 6c of the panel main body 6 on the lower side in a state of protruding inward in the left-right direction from the extending portion 7h. Therefore, the end cover 7 can grip the protruding portion 7f and insert / 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. It is possible to reduce the amount of output as much as possible and reduce the deterioration of the appearance of the waterproof panel 5.
Further, since the sealing end portion 8a and the sealing main body 8 facing each other facing each other are bonded to each other to be waterproofed, it is possible to prevent water from leaking from the sealing end portion 8a.

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 surface of the left-right outer surface plate 7b and the bottom plate 7c of the end cover 7. Although the waterproof panel 5 is divided into an end cover 7 and a panel body 6 for easy maintenance, airtightness can be ensured.
Further, in this case, since the angle member 6a provided on the panel main body 6 is provided with the steady rest body 10 for holding the waterproof panel 5 in the left-right direction, the waterproof panel 5 is displaced in the left-right direction. The amount becomes slight, the positional deviation of the seal end 8a with respect to the pressing body 9c in the left-right direction becomes small, and the left-right even pressing deformation of the seal end 8a is performed, so that the waterproof property is improved.

In this reference example, as in the embodiment shown in FIG. 11, the groove width of the guide rail 4 is wide, the waterproof panel 5 is displaced in the front-rear direction, and the seal end portion 8a is deformed by pressing the pressing body 9c. If there is a risk of biasing, a front-rear steady rest body 11 for preventing the front-rear steady rest of the waterproof panel 5 can be provided on the front-rear direction outer surface of the front-back plate 7a of the end cover 7. As a result, the seal end portion 8a is deformed evenly on the left and right sides, and the waterproof property is improved.

Next, the present embodiment will be described in the drawings after FIG.
In this case, since the shutter curtain 1 is wider in the left-right direction than that in the first embodiment, it is subject to higher water pressure, and the thickness of the waterproof panel 21 in the front-rear direction is adjusted to withstand this. It is thicker than the groove width of the guide rail 4 within the inner dimensions of the guide rail 4.
Since the waterproof panel 21 is wide and thick on the left and right, it is heavy, and when it is a single item, it becomes difficult to install it on the left and right guide rails 4, and it becomes a large-scale transport to the site, so that it is configured as a split type. There is. The number of divisions is not particularly limited, but it is preferably an odd number. The reason is that when an odd number of sheets is used, there is no division position in the central portion in the left-right direction of the waterproof panel 21, and there is an advantage that the water pressure resistance is improved. In the following embodiment, the waterproof panel 21 divided into three parts will be described.

The waterproof panel 21 is composed of a panel main body 22 and an end cover 7 as in the case of the first embodiment. The panel main body 22 is configured by using a central panel (connecting panel) 24 and a pair of symmetrical end panels 25, and the central panel 24 and the left and right end panels 25 have the same left and right lengths.

To.
In the present embodiment, the seal body 8 attached to the bottom surface of the panel body 22 is 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 parallel to the outdoor side, but this may be provided on the indoor side or a pair may be provided indoors or outdoors.
Incidentally, since the end cover 7 has the same structure as that of the above-described embodiment, the details thereof will be omitted.
Further, an L-shaped reinforcing metal fitting 26 is 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 at the central portion in the left-right direction, and by configuring in this way, the divided position of the reinforcing metal fitting 26 and the divided position of the panel main body 22 are displaced from each other. It is configured to increase the strength. In this case, it is preferable that the reinforcing metal fitting 26 is provided at a lower position of the panel main body 22 in order to secure the strength. Incidentally, the reinforcing metal fitting 26 may be a single reinforcing metal fitting 26 instead of a split type.

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

As for the arrangement of such angle members, it is of course possible that the panel bodies abut each other at the divided portions of 24a and 25a, but for example, the protruding side may be the fourth angle member 25c on the end panel 25 side, and the angle may be set. The butt position between the materials can be greatly deviated as the intermediate position in the left-right direction of the end panel 25 or the intermediate position in the left-right direction of the center panel 24, and by doing so, the butt positions of the angle materials are greatly inconsistent. As a result, the panel bodies will be displaced from the connection position, and the strength can be further increased. When the fourth angle member 25c is lengthened, the procedure for incorporating the waterproof panel 22 is as follows: after setting the center panel 24, the end panel 25 is lifted and the guided portion 25e is fitted in the guide rail 4. After the end panels 25 are lowered and set on both the left and right sides of the central panel 24, the panel main body 22 can be assembled by connecting the first and second connecting portions 24d and 25d to each other.

Also, when the seal end 8a is worn, only the end cover 7 is removed from the panel body 22 to replace the seal end 8a, and then the end cover 7 is attached again, as in the above reference example. This makes it easy to perform maintenance work for replacement.
