Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for upper and lower ends of a water-resistant board that covers the front surface of a waterproof structure for a rising portion from a flat roof floor such as a parapet or a rooftop tower.

[0002]

[Technical Background] The waterproofing treatment of a flat roof will be described with reference to FIG. 1. First, a waterproof layer 4 is formed on a rising portion 2 from a floor portion 1 after a floor portion waterproof layer 3 is formed. A pressing material layer 5 is formed on the upper surface of the waterproof layer 3, and a water resistant board 6 is provided on the surface of the rising waterproof layer 4 to protect the waterproof layer 4 from sunlight and the like. The upper and lower ends of the board 6 are
The upper holder 10 and the pressing material layer 5 fixed to the rising portion 2
Supported by the lower holders 20 fixed to (floor 1),
The upper holder 10 is provided with a holder cover plate 13 that covers the upper surface thereof and reaches the front surface of the board 6 to drain water.

[0003]

In the above waterproof structure, each holder 10 at the upper and lower ends of the water resistant board 6,
The support by No. 20 is supported by the applicants in the actual application 1-1.
There is a device described in Japanese Patent No. 29419. As shown in FIG. 29, the present invention has a configuration in which the upper and lower ends of the board 6 are fitted in the downward or upward U-shaped members 101 and 201 of the upper and lower holders 10 and 20, and the upper end of the board 6 is attached to the upper holder 1.
After being deeply fitted into the U-shaped member 101 of 0, the lower end is dropped into the U-shaped member 201 of the lower holder 20 to support the board 6 on both holders 10 and 20.

However, in this invention, since the upper and lower ends of the board 6 are fitted by dropping the board 6, after the board 6 is fitted in the holders 10 and 20, the fitting degree of the upper end of the board 6 in the holder 10 is set. Difficult to confirm,
When the fit is shallow, the board 6 may come off due to wind pressure or the like. Therefore, 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 slope of the floor surface of the flat roof, the board 6 is sufficiently fitted to the upper holder 10 and can be cut into a height dimension that can be easily dropped. Annoying and poor workability.

Further, since the board 6 is provided within the range of 1 m near the floor 1, the mounting is a moderate work, and the upper end of the board 6 is fitted into the upper holder 10 by moving the board 6 from the lower side to the upper side. It is a movement to move. For this reason,
The fitting part (fitting hole) is hard to see, making it difficult to work. Further, if the board 6 is loosely fitted to the holders 10 and 20, there is a risk that the board 6 rattles and is disengaged by wind pressure or the holders 10 and 20 are damaged. If the fitting is tight, it becomes difficult to fit the board 6.

In view of the above points, the present invention stops the mounting by dropping the board and reduces the mounting by fitting in the vertical direction, that is, moving the board in the front-back direction in the upper or lower end thereof. Therefore, it is an object to improve workability by enabling the attachment.

[0007]

In order to solve the above problems, in the structure for supporting the water resistant board by the above-mentioned upper and lower holders, in the first to sixth inventions, the support of the board upper end is devised. In the first invention (the invention according to claim 1), the holder cover plate is attached to the upper holder by fitting, and the upper end of the water resistant board extends to the lower side of the lower surface of the upper holder. And the holder cover plate is interposed between the downward pieces and is sandwiched by the abutting piece and the downward piece.

According to the first aspect of the invention, the holder cover plate and the upper holder are fitted to each other through the fitting piece that is movable in the length direction of the holder cover plate. (The second invention according to claim 2).

According to a third aspect of the present invention (the invention according to claim 3), 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 the upper holder. It is connected to the main body so that it can be bent, and there is a locking means with the holder main body that keeps it facing downward.When the locking is done, the upper edge of the water resistant board is clamped by both contact pieces. It has been configured.

In the third aspect of the invention, instead of the locking means, the front side contact piece may be screwed to the rear side contact piece (the fourth invention of claim 4). . Further, instead of the locking means, the front-side pad piece may be kept downward by its own bending, and the upper end of the water resistant board may be screwed to the rear-side pad piece 12. (5th invention of Claim 5).

In the first to fifth inventions, an elastic material may be interposed between the upper end of the water resistant board and the abutting piece or the downward piece (a sixth aspect of the invention).

In a seventh aspect of the invention (the invention according to claim 7), the support of the lower end of the board is devised, and the structure is such that the lower holder has an upward section cross section into which the lower end of the water resistant board is fitted. The U-shaped portion has a U-shaped portion, and the U-shaped portion is composed of a pair of divided parts each having only one standing wall on both sides, and the two divided parts are integrated by fitting.

Also in the seventh invention, an elastic material may be interposed between the lower end of the water resistant board and one of the standing walls of the lower holder (the eighth invention according to claim 8).

[0014]

According to the present invention thus constructed, one of the upper and lower ends of the water-resistant board is applied to the rear surface of the back piece of the upper holder or one of the divided parts of the lower holder after the rear surface thereof is applied.
It is supported by fitting the holder cover plate, the front contact piece of the upper holder, or the other divided part of the lower holder to the upper holder, the upper holder body, or one of the divided parts. At this time, since the application of the upper and lower ends of the water resistant board to the application piece or the like is an operation in the front-rear direction, the work 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 then the support member can be fitted to support the other member, the other one of the boards is supposed to be provided. It may be fitted in the vertical direction. Therefore, in cutting the board, it is not necessary to consider the height dimension for dropping, and workability is improved.

Further, since the degree to which the upper and lower ends of the board are applied to the support members can be visually observed before the two support members are fitted to each other, the support can be surely performed.
