Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for a rising portion from a floor roof, such as a parapet or a rooftop tower, which supports upper and lower ends of a waterproof board covering the front surface thereof. It is about structure. 2. Description of the Related Art Waterproofing of a flat roof will be described with reference to FIG. 1. First, following a floor waterproof layer 3, a waterproof layer 4 is formed on a rising portion 2 from the floor 1 to form a floor. A pressing material layer 5 is formed on the upper surface of the waterproof layer 3 of the part 1, and a waterproof board 6 for protecting the waterproof layer 4 from sunlight or the like is provided on the surface of the rising waterproof layer 4. The upper and lower ends of the board 6
Upper holder 10 and holding material layer 5 fixed to rising portion 2
(Floor part 1) supported by lower holders 20 fixed to each other,
The upper holder 10 is provided with a holder cover plate 13 that covers the upper surface and drains water to the front of the board 6. In the above-mentioned waterproofing structure, the holders 10 at the upper and lower ends of the waterproof board 6 are provided.
20 was supported by the applicant of the present application,
There is a device described in Japanese Patent No. 29419. The present invention has a configuration in which the upper and lower ends of the board 6 are fitted to the U-shaped members 101 and 201 of the upper and lower cross-sections of the upper and lower holders 10 and 20, as shown in FIG.
After fitting deeply into the U-shaped member 101 of 0, the lower end is dropped into the U-shaped member 201 of the lower holder 20, and the board 6 is supported by both holders 10,20. However, in the present invention, since the upper and lower ends of the board 6 are fitted by dropping the board 6, after the board 6 is fitted into the holders 10 and 20, the degree of fitting of the upper end of the board 6 into the holder 10 is determined. Hard to see,
If the fitting is shallow, the board 6 may come off due to wind pressure or the like. For this reason, the height accuracy of the board 6 must be increased. Since the height of the board 6 changes in the length direction (inclination direction) based on the gradient of the floor surface of the flat roof, it is necessary to cut the board 6 into a height dimension that can be sufficiently fitted into the upper holder 10 and easily dropped. Annoying and poor workability. [0005] Further, since the board 6 is provided within a range of about 1 m near the floor 1, its mounting is a midway work, and the upper end of the board 6 is fitted into the upper holder 10 by pushing the board 6 upward from below. It is a moving action. For this reason,
The fitting portion (fitting hole) is difficult to see and work is difficult. Furthermore, if the fitting of the board 6 to the holders 10 and 20 is loose, the board 6 may rattle, come off due to wind pressure or the like, or the holders 10 and 20 may be damaged. If the fitting is tight, it becomes difficult to fit the board 6. In view of the above, the present invention is intended to stop the mounting by dropping the board and reduce the mounting by vertical fitting, that is, to move the board in the front-rear direction at its upper end or lower end. An object of the present invention is to improve the workability so that the work can be attached. [0007] In order to solve the above-mentioned problems, in the structure of supporting the water-resistant board by the above-mentioned upper and lower holders, in the present invention, first, the support of the upper end of the board is devised. As one means, the holder cover plate is fitted to the upper holder by fitting, and the upper end of the water-resistant board has an abutting piece extending below the lower surface of the upper holder and a downward piece of the holder cover plate. Between the contact pieces and the downward pieces. According to the present invention, the holder cover plate and the upper holder can be fitted with each other through a fitting piece which can be freely moved and mounted in the length direction of the holder cover plate. As another means, the upper end of the water-resistant board is interposed between front and rear contact pieces extending below the lower surface of the upper holder, and the front contact piece is connected to the upper holder body in a bendable manner. In addition, locking means for holding the holder body downward is provided, and when the locking is performed, the upper end of the water-resistant board is sandwiched between the two contact pieces. In the present invention, instead of the locking means, the front contact piece may be screwed to the rear contact piece. Further, instead of the locking means, the front contact piece may be maintained downward by its own bending, and the upper end of the water-resistant board may be screwed to the rear contact piece 12. . In each of the above inventions, an elastic material may be interposed between the upper end of the water-resistant board and the abutment or downward piece. Next, the present invention is devised to support the lower end of the board. One of the means is devised to support the lower end of the board. The board has a U-shaped section having an upward cross-section in which the lower end is fitted, and the U-shaped part is composed of front and rear divided parts each having only one of the standing walls on both sides, and the rear divided part is the lower part of the rising portion or The front split part is fixed to the floor, and is fitted to the rear split part to be integrated. Also in the present invention, an elastic material may be interposed between the lower end of the water-resistant board and one of the upright walls of the lower holder. According to the present invention constructed as described above, one of the upper and lower ends of the water-resistant board has its rear surface abutted against a back piece of the upper holder or a divided part on the back side of the lower holder. Later
The holder cover plate, the front contact piece of the upper holder, or the front split part of the lower holder is supported by fitting from the front to the upper holder, the upper holder main body, or the rear split part. At this time, the application of the upper and lower ends of the water-resistant board to the application pieces and the like is performed in the front-back direction,
The task is easy. As described above, if one of the support members at the upper and lower ends of the board is divided, and one end of the support member is put into the support member and can be supported by fitting the support member, the other is temporarily provided on the board. May be inserted vertically. Therefore, when cutting the board, it is not necessary to consider the height dimension for dropping, and the workability is improved. Before the two support members are fitted, the upper and lower ends of the board are applied to the support members, so that the degree of contact can be visually checked. As shown in FIGS. 1 and 2, a rising waterproof layer 4 is formed on the inner surface of a parapet (rise section) 2 from a waterproof layer 3 on a slab concrete 1 (floor section) of a flat roof floor. The upper end is fixed by screws 17 also for fixing the upper holder 10 (FIG. 3A). A pressing material layer (pressing concrete layer) 5 is formed on the upper surface of the waterproof layer 3 of the slab concrete 1, and a cushion material 3 a is interposed at an interface with the parapet 2. This cushion material 3

Similarly, the fitting portion 13b of the holder cover plate 13 can be made movable via the groove. The embodiment shown in FIG. 11 differs from the embodiment shown in FIG. 2 in that the abutment piece 12 is provided by fitting, and in the embodiments shown in FIGS. 5 and 6, as shown in FIG. The support 16 may be a fitting structure with only the upper end. In the embodiment shown in FIGS. 12 and 13, the shapes of the fitting portions 13a and 13b of the holder cover plate 13 are changed. In the embodiment shown in FIG. The stopper cap 13d is fitted. Various types of caps 13d can be used as shown in FIGS. In the embodiment shown in FIG. 14, the holder cover plate 13 is also used by the upper holder 10, and the contact piece 12a is further provided on the front edge thereof so as to be bendable. After applying the upper end of the water-resistant board 6 to the rear contact piece 12, the front contact piece 12a is bent against the upper holder main body 10a as indicated by the solid line in FIG. The upper end of the water-resistant board 6 is supported by both contact pieces 12 and 12a by being fitted to the claws of the upper holder body 10a. The embodiment shown in FIG. 15 is different from the embodiment shown in FIG. 14 in that a plurality of bent grooves t of the contact piece 12a are formed so as to cope with a change in the thickness of the board 6.
In this case, the board 6 is fixed with screws b as shown by solid lines or chain lines in FIGS. In this case, the upper holder 10 may be made of aluminum. In the embodiment shown in FIG. 16, the contact piece 12a is attached by fitting, and the contact piece 12a may be fixed with a screw b. In the embodiment shown in FIG. 17, the contact piece 12a is divided into a board 6 supporting piece 12b and a draining piece 12c, which can be bent, and a plurality of bent grooves t are formed. obtain. It should be noted that even if the holder cover plate 13 is not used by the upper holder 10 (FIGS. 1 to 13), the downward piece 13c of the holder cover plate 13 can be bent in the vertical direction. In the embodiment shown in FIG. 18, the pair of divided parts 21 of the lower holder 20 have different cross-sectional shapes. In this case, as shown in FIG. 19, the other divided part 22 may be connected to the one divided part 21 in a bendable manner. FIGS. 20 and 21 show another embodiment of the lower holder 20. FIG. In the embodiment shown in FIG. 22, the divided part 21 of the lower holder 20 is further divided, and the fitting of the part pieces 21a 'is made like a solid line or a dashed line to thereby reduce the thickness of the board 6. Can respond to changes. The fitting is not limited to two steps, but can be three or more steps. In the embodiment shown in FIG. 23, the divided parts 22 of the lower holder 20 are mounted by vertically fitting. In the embodiment, the support structure of the upper and lower ends of the water-resistant board 6 is used as the holder cover plate 1 according to the present invention.
Although three or divided parts 22 are fitted, only one of them may be configured according to the present invention, and the other may be configured according to the related art as shown in FIG. 29 described above. Incidentally, the invention relating to the lower holder 20 can also be employed in a skirting type rising portion structure as shown in FIG. 24. Further, as shown in FIG. It goes without saying that the present invention can also be applied to a structure directly fitted into the upper lower surface (the upper holder 10 formed on the lower surface of the neck). For this reason, the case where the upper holder 10 is directly formed with the rising wall is included. The lower holder 20 may be attached to the lower portion of the front surface of the rising portion 2 as shown in FIGS. 26 and 27, instead of the floor portion 1 (pressing material layer 5).
Instead of using the lower holder 20, a known means such as a mortar m as shown in FIG. 28 may be employed.
In this case, only the effect of fitting the upper end of the water-resistant board 6 into the upper holder 10 in the front-rear direction is obtained. The structure of the lower holder 20 shown in FIG.
As shown in FIG. 18 to FIG. 23, it is possible to use the divided parts 21 and 22. The present invention is constructed as described above, and the water-resistant board is formed by a holder cover plate, a front contact piece or a divided part of a lower holder which forms a part of the holder regardless of dropping. Since the holder is formed and supported by fitting, if the water-resistant board has a height that securely locks to the upper and lower holders, the locking is surely performed, and the height of the water-resistant board is Accuracy is not required, and the locked state can be visually confirmed before the support member is fitted. At this time, if an elastic material is interposed, the degree of the interposition of the elastic material can also be confirmed, and the water-resistant board 6 can be sufficiently supported. As described above, high accuracy is not required for the construction of the upper and lower holders and the height dimension of the water-resistant board, and the locking state between the water-resistant board and the upper and lower holders can be visually checked, so that the work is complicated. The water-resistant board can be reliably supported on the upper and lower holders without causing the occurrence of rattling due to wind or the like. Further, if the holder cover plate and the upper holder are fitted via a movable fitting piece, the fitting can be performed at several points at required positions, and the fitting is facilitated. The mounting of the upper holder becomes easy, and workability is improved. Further, when the holder cover plate is also used as the upper holder and the front contact piece can be bent in the vertical direction, the number of parts is reduced, the cost is reduced, and the number of steps is reduced.
