Hereinafter, embodiments of the present invention will be described with reference to the drawings. As used herein, the “front-rear direction” is the “entrance direction of the opening (look direction)”, and the “left-right direction” is the “left-right width direction of the opening (finding direction)”. "Direction outward" refers to "the direction from the left and right center of the opening toward the outside in the left and right direction", and "Inward in the left and right direction" refers to "the direction from the left and right ends of the opening toward the center of the left and right direction" “Inner surface” is defined as “surface that can be seen from the left and right center of the opening”, and “outer surface in the left and right direction” is defined as “surface that can be seen from both the left and right sides of the opening” for convenience. is not.
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 shutter device for building, and the shutter curtain 1 is formed by connecting slats 1a in a vertical direction by interlocking connection, and an upper end edge is formed. It is connected to a winding drum 2 provided on the ceiling. The shutter curtain 1 is moved up and down by being guided by guide rails 4 provided on the left and right sides of the opening when the winding drum 2 is rotated based on forward and reverse driving of the electric switch 3. This is the same as before.

  Reference numeral 5 denotes a waterproof panel (waterproof panel). The waterproof panel 5 includes a single panel-shaped panel body 6 and a groove-shaped end cover 7 that is removably attached to the left and right ends of the panel body 6. However, the panel body 6 is dimensioned so that the left-right width fits into the guide groove 4 a of the left-right guide rail 4 and the panel thickness loosely fits the guide rail 4. An angle member 6a is attached to the upper end surface of the panel body 6, and a bolt 6b, which is an example of a tightening tool, is a slat (no lower interlock joint) 1b of the shutter curtain 1 on the angle member 6a. It is fixed through.

The end cover 7 includes a front and back plate 7a, a left and right outer surface plate 7b, and a bottom plate 7c. The end cover 7 has a groove shape that is open in the upper and lower directions and the inner side in the left and right directions. The dimensions are set so as to be 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 adhered to the inner surfaces of the outer surface plate 7b and the bottom surface plate 7c. The airtight seal 7d is attached to the left and right ends of the panel body 6. If it is fitted so as to be pressed against the outer surface plate 7b and the bottom surface plate 7c of the end cover 7, it becomes a crushed state and exhibits airtightness. In this state, the inner end edge 7i of the front and back plates 7a is dimensioned to extend inward in the left-right direction from the guide groove 4a of the guide rail 4, and an extension portion 7h is formed. And this extension part 7h will be detachably fixed to panel body 6 via screw 7e which is an example of a fastener, but in this embodiment, when panel body 6 is thin, The vertical position is set to be shifted 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 inner edge 7j in the left-right direction of the end cover bottom plate 7c protrudes longer inward in the left-right direction than the inner edge 7i of the extending portion 7h of the front and back plates 7a, thereby forming a protruding portion 7f. The end cover 7 comes into contact with the bottom plate 6c of the panel body 6 in a state where the airtight seal 7d is sandwiched between the projection 7f projecting inward in the left-right direction from the front and back plates 7a. Thus, as will be described later, it is considered that the operation of attaching / detaching the end cover 7 to / from the panel main body 6 can be performed by grasping the protruding portion 7f, whereby the extension amount of the extension portion 7h from the guide rail 4 is achieved. Is reduced, and the fixing portion of the end cover 7 by the screw 7e is brought close to the guide rail 4 to reduce the appearance loss.
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 steadying body (not shown) provided at the lowermost slat 1b. It is for avoiding.

8 and 8a are a seal body and a seal end part constituting the waterproof seal S, and the seal body 8 is adhered to the bottom plate 6c of the panel body 6 by, for example, a double-sided adhesive tape, and the seal end part 8a. Are attached in the same manner in a state extending from the outer surface of the end cover outer surface plate 7b through the outer surface of the corner portion 7g to the inner edge 7j of the bottom surface (that is, the outer peripheral surface) of the bottom surface plate 7c. 8. The seal end portion 8a is made of, for example, a low-rebound rubber elastic material, but the seal body 8 and the opposite portion 8b facing each other at the edge portion of the protruding portion 7f of the seal end portion 8a are made of an adhesive. It is bonded and integrated so that there is no gap. In addition, since the seal body 8 has a structure for closing the abutting portions from the front and rear of the plate surface of the bottom surface plate 6c of the panel body 6, it contributes to waterproofing into the panel body 6.
The seal end 8a is attached and integrated so as to be bent at the corner 7g of the outer surface plate 7b and the bottom plate 7c of the end cover 7, but the outer periphery of the corner 8c of the seal end 8a Since the waterproof seal S is thick in the height direction, the surface has a structure curved in an arc shape even when it is bent at the corner portion 7g.

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 fastening tool, into the groove bottom surface 4b into a mounting hole 9l that is long in the vertical direction. The substrate 9b is fixed, and the pressing body 9c protrudes inward in the left-right direction from the substrate 9b. The substrate 9b is narrower than the guide groove 4a, and the existing guide groove 4a. Can be retrofitted.
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 reaches the intermediate position in the vertical direction of the substrate 9b, and the first pressing portion 9d The second pressing portion 9e that reaches the vicinity of the floor surface F in a state where the protruding amount of the lower end is maintained, the lower end is in contact with the floor surface F, and the inner edge (that is, the top side) 9m of the pressing body 9c is the lower end side. The third pressing portion 9f is formed by the third pressing portion 9f which is inclined so as to gradually become lower through the arc-shaped corner portion 9j so as to protrude inward in the left-right direction, and reaches the floor surface F. 9f is such that the inner end 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 and right inner end 9g of the third pressing portion 9f is processed so as not to have a step with respect to the floor surface F, whereby the left and right inner end 9g of the seal end portion 8a is in contact with the pressed portion. Is set so that there is no gap.
Note that the pressing tool 9 of the present embodiment has a flat board 9b with a fitting hole 9h as shown in FIG. 7, and a protrusion 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, there are various shapes such as a square shape (the corner portion is preferably chamfered), an arc shape, and a mountain shape. It can be made into a shape.

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 the lower side and are deformed by pressing. . 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 in the deepest deformation amount, and finally the seal body 8 provided on the bottom plate 6c of the panel body 6. The bottom portion 8e provided on the bottom plate 7c of the end cover 7 abuts against the floor surface F and is crushed and deformed, thereby waterproofing the bottom portion and both left and right end portions of the waterproof panel 5. ing.
In this case, the corner portion 8c in which the outer peripheral surface of the seal end portion 8a is arcuate is pressed by the corner portion 9j of the pressing body 9c formed in the same arcuate shape (the curvature 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 seal end portion 8a at the obtuse corner portion is formed. The arc-shaped corner portion 8c is set so as to avoid the possibility that the pressure deformation at the corner portion 8c becomes insufficient and the water leaks easily. It is not necessarily required to be arcuate.
As a countermeasure for preventing water leakage at the corner portion 9j of the pressing body 9c, the corner portion 9j is limited to an arc shape (a larger curvature) than the arc of the corner portion 8c of the seal end portion 8a. For example, a small arc shape as shown in FIG. 10 (A) may be used. Further, as shown in FIG. 10 (B), the corner portion 9j may be formed between the second pressing portion 9e and the third pressing portion 9f. A fourth pressing portion 9k that is linear 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 so that it can be advised to avoid water leakage. In this, as shown in FIG. 4D, the two corners 9j where the apexes intersect each other are arcuate, and the fourth pressing part 9k is further formed into two or more polygonal shapes. You can also

When the opening and closing of the shutter curtain 1 is repeated in this manner, the outer surface of the seal end 8a provided on the outer surface plate 7b in the left-right direction of the end cover 7 slides on the first to third pressing portions 9d, 9e, 9f. In such a state, the pressure deformation is repeated in the moving state, and it is consumed. In such a case, maintenance for replacing the seal end 8a is required.
As a maintenance method in this case, the step of removing the screw 7e of the extending portion 7h, the step of extracting the end cover 7 from the panel body 6, the step of extracting the end cover 7 from the guide rail 4, and the end cover 7 are provided. The step of replacing the seal end portion 8a, the step of fitting the end cover 7 with the replaced seal end portion 8a into the guide rail, and the end cover 7 with the replaced seal end portion 8a at the extension portion 7h in the panel body 6 In this state, for example, the shutter curtain 1 is raised to a position where the lower edge of the waterproof panel 5 does not contact at least the first pressing portion 9d. Then, the opposite part (adhesive part) 8b between the seal body 8 and the seal end 8a is cut, and the screw 7e for fixing the end cover 7 to the panel body 6 at the extended part 7h is removed. The end cover 7 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, whereby the pulled out end cover 7 is a single unit. Thus, the seal end 8a can be replaced. Then, the end cover 7 whose seal end 8a has been replaced can be assembled into the panel body 6 in the reverse procedure.
This procedure is effective when the bottom plate protrusion 7f is fixed to the bottom plate 6c of the panel body 6 by screws 7e. The screws 7e fixed to the bottom plate 6c are provided on the seal end 8a. The bottom portion 8e can be removed from the bottom plate protrusion 7f so that the screw 7e is exposed.

Furthermore, as another specific maintenance method, the shutter curtain 1 is lifted after the screw 7e is removed from the extending portion 7h in a state where the shutter curtain 1 is in the fully closed position (or a position close to the fully closed position). The end cover 7 is extracted from the panel body 6. Thereafter, the end cover 7 is pulled out from the guide rail 4, the seal end 8a is replaced in the extracted end cover 7, and the end cover 7 in which the seal end 8a is replaced in the reverse procedure is replaced with the panel. You may make it attach to the main body 6. FIG.
This procedure is effective when the bottom plate protrusion 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 at the extending portion 7h. Then, 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 steadying bodies 10 are provided to prevent the waterproof panel 5 from swinging left and right. The steady rest 10 is composed of a plate-like support member 10a and a roller 10b attached to the outside of the support member 10a in the left-right direction. The support member 10a has a long hole 10d which is long in the left-right direction. As a result, the left and right mounting positions can be adjusted by bolts (tightening members) 10c with respect to the angle member 6a of the steady rest 10 and the roller 10b is slightly spaced from the guide rail groove bottom surface 4b (for example, 2 mm). In order to prevent the waterproof panel 5 from shifting in the left-right position, the pressing deformation of the seal end 8a by the pressing body 9c is made as uniform as possible from side to side. In this case, the steady rest 10 needs to be mounted so as to be accurately positioned. Therefore, in this embodiment, as shown in FIG. 9, a bolt 10c and a fixing screw (tightening tool) 10e are used. After the steady rest 10 is accurately positioned, it is securely fixed with the fixing screw 10e.
In this case, an L-shaped reinforcing bracket 12 is fixed to the panel body 6 via a bolt 12a on the indoor side, but the reinforcing bracket 12 is provided only on the outdoor side and on both the indoor and outdoor sides. Also 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 the upper left corner of the panel main body 6 in the left-right direction. The auxiliary metal fitting 13 serves as a guide for attaching the end cover 7 to the panel main body 6. The function of the maintenance work is improved.

  In the present embodiment configured as described, the guide rails 4 provided at the left and right ends of the opening are moved up and down to open and close the opening, and the left and right ends are the guide rails 4. A waterproof panel 5 fitted inside and guided to rise and fall, and a waterproof seal provided so as to extend from the left and right outer surface plate 7b of the end cover 7 which is the left and right side surfaces of the waterproof panel 5 to the bottom plate 7c through the corner portion 7g. S and a press which is provided so as to protrude inward in the left-right direction from the groove bottom surface 4b of the guide rail 4 and which waterproofs both the left and right sides by pressing and deforming the seal end 8a attached to the end cover 7 of the waterproof seal. The body 9c is provided to waterproof the lower portion of the opening, and as a result, the corner portions of the waterproof seal S which are provided on the left and right side surfaces and the bottom surface of the waterproof panel 5 are waterproof panel. 5 is also pressed and deformed up to the bottom surface portion inside the outer edge 6e in the left-right direction, and the corner portion 8c of the seal end 8a where the weight of the panel body 6 does not directly act is also reliably deformed by pressure. It becomes waterproof.

In addition, the pressing body 9c that presses and deforms the bottom surface portion 8e of the seal end 8a is not visually recognized because it is accommodated in the guide rail 4, and the appearance is not impaired. Moreover, since the pressing body 9c can be pressed and deformed in a state where the entire seal end portion 8a is continuous, the waterproof performance is not impaired while the structure of the pressing body 9c can be simplified.
Further, the seal end portion 8a is provided so that a single one is bent at the corner portion 7g of the end cover 7, so that the outer peripheral surface of the corner portion 8c is arcuate, and the arcuate corner is formed. Since the portion 8c is pressed and deformed by the arcuate corner portion 9j of the pressing body 9c, the pressing deformation becomes closer to the ideal and the waterproof property can be further improved.
Further, the third pressing portion 9f of the pressing body 9c presses the bottom side portion 8e of the seal end portion 8a, and the third pressing portion 9f is inclined so as to become lower toward the distal end side, and the distal end thereof is Since there is no step between the floor surface, the pressure deformation of the bottom side portion 8e of the seal end portion 8a reaches the floor portion F in a natural state with no step. Therefore, it is possible to effectively avoid the deterioration of the waterproof performance in the case and to exhibit high waterproof performance.

Furthermore, in the present embodiment, the following functions and effects are also exhibited.
The shutter curtain 1 moves up and down the guide rails 4 provided at both left and right ends of the opening to open and close the opening. The left and right ends of the shutter curtain 1 are connected to the guide rail 4. A waterproof panel 5 is provided that is fitted inside and guided up and down. The waterproof panel 5 is detachably fixed to the panel body 6 in a state in which both left and right end portions are fitted into the guide rail 4 and the left and right end portions of the panel body 6 are detachably fitted. A waterproof seal S for waterproofing the lower portion of the opening is configured with a seal body 8 attached to the bottom plate 6 c of the panel body 6, and the end cover 7. When the shutter curtain 1 is in the closed position, the seal body 8 and the bottom portion 8e of the seal end 8a are configured to be provided with seal end portions 8a provided on the outer peripheral surfaces of the left and right outer surface plates 7b and the bottom plate 7c. Is brought into contact with the floor surface F and crushed to exhibit a waterproof function, and the left and right side surface portions 8d and the corner portion 8c of the seal end 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.

  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 and the left and right side surface portions 8d of the seal end portion 8a are in contact with the pressing body 9c. The contact is repeated each time the shutter curtain 1 is opened and closed, so that it is consumed quickly. If the shutter curtain 1 is left as it is, the waterproof property is impaired, and maintenance for replacing the seal end 8a is required.

  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 8a are bonded is cut, and the guide rail When the screw 7e is removed at the extended portion 7h that extends inward in the left-right direction from 4 and is exposed to the front surface of the waterproof panel 5 and is easy to work with, the end cover 7 is detached 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 where it is 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 do.

  As described above, the embodiment in which the present invention is implemented is a maintenance in which the seal end portion 8a is replaced while the seal end portion 8a and the pressing body 9c are provided in the guide rail 4 so that they cannot be seen from the outside. The work can be easily performed without removing the waterproof panel 5 from the guide rail 4.

  In addition, in this case, the seal end portion 8a attached to the left and right outer surface plates 7b and the bottom surface plate 7c of the end cover 7 is provided as an integral part so as to bend the corner portion 8c. Compared to the case where the seal end portion 8a is provided as a boundary, the replacement work of the seal end portion 8a is facilitated.

In addition, the bottom plate 7c of the end cover 7 is provided with a protruding portion 7f that is laminated on the bottom plate 6c of the panel body 6 on the lower side in a state of protruding further inward in the left-right direction than the extending portion 7h. Therefore, the end cover 7 can grip and remove the end cover 7 from the panel body 6 by grasping the projecting portion 7f. As a result, the extension of the extension portion 7h fixed through the screw 7e is achieved. It is possible to reduce the amount of protrusion as much as possible and reduce the deterioration of the appearance of the waterproof panel 5.
Moreover, since the opposing part 8b which the seal | sticker edge part 8a and the seal | sticker main body 8 mutually oppose is adhere | attached, since waterproofing processing is performed, it can prevent that a water leaks 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 left and right outer surface plates 7b and the bottom surface plate 7c of the end cover 7. Although the waterproof panel 5 is divided into the end cover 7 and the panel body 6 so that maintenance is easy, airtightness can be secured.
In addition, in this case, the angle member 6a provided in the panel body 6 is provided with the steadying body 10 for securing the waterproof panel 5 in the horizontal direction. It becomes a little thing, the position shift of the seal end part 8a with respect to the pressing body 9c in the left-right direction is small, and the pressure deformation of the seal end part 8a on the left and right is made uniform, and the waterproofness is improved.

  Needless to say, the present invention is not limited to the above embodiment, and the groove width of the guide rail 4 is wide and the waterproof panel 5 is positioned in the front-rear direction as in the embodiment shown in FIG. When there is a possibility that the pressing deformation of the seal end 8a with respect to the pressing body 9c is shifted and the front and back plates 7a of the end cover 7 are attached to the front / rear direction outer surface of the waterproof panel 5 in the front / rear direction. The back-and-forth backrest body 11 can be provided, whereby the left and right seal end portions 8a are pressed and deformed evenly and the waterproofness is improved.

Furthermore, the second embodiment after FIG. 12 will be described. In this case, the shutter curtain 1 is wider in the left-right direction than in the first embodiment, so that it receives a higher water pressure, and the thickness of the waterproof panel 21 in the front-rear direction is set so as to withstand this. The guide rail 4 is thicker than the groove width of the guide rail 4 within the inner dimensions of the guide rail 4.
And since this waterproof panel 21 is wide and thick on the left and right sides, it is heavy, making it difficult to install the waterproof panel 21 on the left and right guide rails 4 and transporting it to the site. Yes. The number of divisions is not particularly limited, but is preferably an odd number. The reason for this is that when an odd number is used, there is no division position at the central portion in the left-right direction of the waterproof panel 21 and the water pressure resistance is improved. In the following second embodiment, the waterproof panel 21 divided into three parts will be described.

  The waterproof panel 21 is constituted by the panel body 22 and the end cover 7 as in the case of the first embodiment. The panel body 22 is configured using a center panel (connection panel) 24 and a pair of symmetrical end panels 25. The center panel 24 and the left and right end panels 25 have the same left-right length. The center panel 24 and the left and right end panels 25 may have different left and right lengths, and the end panels 25 may be different from each other. They are the same length, but the center panel 24 may have a length different from the end panel 25 (the length may be longer or shorter), and the one end panel 25 and the center panel 24 may be The length may be the same, and the length of the other end panel 25 may be different. Furthermore, as a waterproof panel for giving strength, there may be a two-part split type without the connecting panel 24 and only the end panel 25. In this case, the connecting end edge as a split part is the waterproof panel. The strength can be increased by assuming that the position is shifted in either the left-right direction, not the center position in the left-right direction. In this case, it goes without saying that any one of the end panels 25k connecting portion has the configuration of the first connecting portion 24b of the first embodiment.

The central panel 24 includes a central panel main body 24a configured in a thick box shape, and first and second angle members 24b and 24c having an inverted L shape fixed to the upper end surface of the central panel main body 24a, The first connecting portion 24d is provided at both the left and right ends of the central panel body 24a.
The first and second angle members 24b and 24c are welded to the upper surface of the central panel main body 24a in a state where the vertical pieces are abutted back to back. In the present embodiment, the first angle member 24b on the outdoor side coincides with the left and right length of the central panel body 24a, but the second angle member 24c has both end edges longer than the left and right lengths of the center panel body 24a. Yes.
Further, in the present embodiment, the first connecting portion 24d is formed as an extending portion 24k extending from the front and back plates 24j of the central panel main body 24a outward in the left-right direction, but the left and right end surfaces of the central panel main body 24a. For example, it may be configured by welding a straddle portion of a U-shaped mold material. And in this thing, the lower end edge of the 1st connection part 24d is the notch part 24f notched by the board | plate thickness of the baseplate 24e.

The end panel 25 includes a box-shaped thick end panel main body 25a, inverted L-shaped third and fourth angle members 25b and 25c fixed to the upper surface of the end panel main body 25a, A second connecting portion 25d fixed to the inner side in the left-right direction of the panel body 25a and a left-right direction outer surface 25i of the end panel body 25 are provided so as to be fitted into the guide groove 4a of the guide rail 4 so as to be loosely fitted. The guided portion 25e is provided.
The third and fourth angle members 25b and 25c are welded to the upper surface of the end panel body 25a with the horizontal pieces being back-to-back. In the present embodiment, the third angle member 25b on the outdoor side coincides with the left and right lengths of the end panel body 25a. However, the fourth angle member 25c has a length corresponding to the length of both end edges of the second angle member 24c. The end panel body 25a is shorter than the left and right lengths.
The second connecting portion 25d has a U-shape in which the leg portion 25h is welded to the front and back plates 25g in a state where the straddling portion 25f extends inward in the left-right direction from the front and back plates 25g of the end panel body 25a. A metal fitting 25i and a leg 25j fitted inside the first metal fitting 25i are constituted by a U-shaped second metal fitting 25k welded to the leg 25h of the first 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 fitting 25i, and the extended portion 24k is connected via a bolt (tightening tool) 22a. The center panel 24 and the end panel 25 can be connected by fixing the part. After the connection, the contact surface portion is caulked with an iron putty, and then the surface of the panel main body 22 is waterproof-coated.

And the waterproof panel 21 of this Embodiment is assembled | attached as follows. First, the left and right end panel main bodies 25a are arranged on the floor surface F so that the guided portions 25e are fitted into the guide rails 4. Next, the central panel main body 24a is lifted, and the first connecting portion 24d is lowered and fitted to the second connecting portion 25d in a male-female manner and installed on the floor surface F. And the panel main body 22 can be assembled by fixing the 1st, 2nd connection parts 24d and 25d through the volt | bolt 22a. Thereafter, the first to fourth angle members 24b, 24c, 25b, 25c are fixed to the lowermost slat 1b via bolts 22b, so that the waterproof panel 21 of the present embodiment can be assembled. It has become.
It should be noted that the male-female fitting structure between the first and second connecting portions 24d, 25d may be an opposite structure. A caulking material is applied in advance to the surface contact portions of the connecting portions 24d and 25d in order 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 in advance to the guided portion 25e. After attaching to 1, the end cover 7 may be attached in a lifted state. The seal body 8 can be attached to the bottom plates 24e and 25g by lifting the panel body 22 from the floor F after the panel body 22 is connected to the shutter curtain 1. However, the seal body 8 is attached in advance in a state of being divided into the bottom plates 24e and 25g. It may be left. When this seal body 8 is a split type, it is considered that the ends of the seal body 8 are bonded to each other with an adhesive after the panel body 22 is assembled so that the waterproof property is not impaired. The
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 what is attached, another seal body 8 is attached so as to be parallel to the outdoor side, but this may be on the indoor side, and a pair may be provided indoors and outdoors.
Incidentally, since the end cover 7 has the same structure as that of the above 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. With this configuration, the dividing position of the reinforcing metal fitting 26 and the dividing position of the panel main body 22 are misaligned. Thus, it is configured to increase strength. In this case, it is preferable to provide the reinforcing metal fitting 26 at the lower position of the panel body 22 in order to ensure strength. Incidentally, the reinforcing metal fitting 26 may of course be a single piece instead of the split type.

  In this case, the second angle member 24c provided on the center panel 24 is long and overlaps with the third angle member 25b of the end panel 25, and the overlapping portion is fixed by the bolt 22b. The strength can be increased even in

  Of course, the angle members may be arranged so as to face each other at the divided portions of the panel bodies 24a and 25a. For example, the projecting side may be the fourth angle member 25c on the end panel 25 side. The abutting position between the materials can be greatly deviated like the middle position in the left-right direction of the end panel 25 or the middle position in the left-right direction of the central panel 24. By doing so, the butting position of the angle materials greatly fluctuated. As a result, it is displaced from the connecting position of the panel bodies, and the strength can be further increased. When the fourth angle member 25c is lengthened, as a procedure for assembling the waterproof panel 22, after the center panel 24 is set, the end panel 25 is lifted and the guided portion 25e is fitted into 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.

And also in this case, when the seal end portion 8a is worn out, after removing only the end cover 7 from the panel body 22 and replacing the seal end portion 8a, as in the first embodiment, the end portion again. By attaching the cover 7, the maintenance work for replacement can be easily performed.
Each of the above embodiments is an electric type in which a waterproof panel is provided at the lower end of the shutter curtain 1, but a manual type in which a waterproof panel alone is installed on a guide rail without providing a shutter curtain. Of course, it is also possible.

  INDUSTRIAL APPLICABILITY The present invention can be used as a waterproof structure for an architectural opening / closing device in which a lower end portion of an opening / closing body such as a shutter curtain is waterproof.
