2. Description of the Related Art Waterproofing of a flat roof will be described with reference to FIG. 1. First, a waterproofing layer 4 is formed on a rising portion 2 from a flooring 1 following a flooring waterproofing layer 3. A pressing material layer 5 is formed on the upper surface of the waterproof layer 3, and a waterproof board 6 is provided on the surface of the rising waterproof layer 4. The upper and lower ends of the board 6 in the rising portion 2 with the jaw 2a are respectively cushioned by the upper holder 10 fixed to the jaw 2a and the lower holder 20 fixed to the holding material layer 5 (floor 1). a is supported.

As means for fixing the upper holder 10 for supporting the upper end of the water-resistant board 6 to the jaw 2a, the applicant of the present application has disclosed in Japanese Patent Laid-Open No. 4-140364.
A technique for embedding and fixing the upper holder 10 simultaneously with driving (casting) the concrete (cement) into the rising portion 2 (at the time of forming the rising portion 2) has been proposed.

In this technique, as shown in FIGS. 8 to 10, an upper holder 10 is provided with a downwardly draining member 102 at a lower portion on both sides of a U-shaped member 101 having a lower surface opening into which an upper end of a waterproof board 6 fits. Is provided. On the other hand, at the time of concrete injection, the fixing piece 40 supporting the upper holder 10 is a member having an upward U-shaped cross section which is driven and fixed to the formwork W with the nail b as shown in each figure. As shown in FIG. 9, the upper holder 10 is fitted.
At the joint of the upper holder 10, a joint is fitted over both upper holders 10, 10 (see FIG. 2).

[0005] In the state of Fig. 9, concrete is poured, and after the concrete is solidified, as shown in Fig. 10, when the formwork W is removed, the fixing piece 40 comes off from the upper holder 10 and the jaw. The upper holder 10 is embedded and fixed in 2a.

[0006]

In the above technique, the upper holder 10, the joint and the fixing piece 40 have conventionally been made of the same material and the same color. For this reason, they may be incorrectly mounted (fixed) because of their U-shaped cross section, etc., and such errors frequently occur in assistants such as part-time workers, and must be reconstructed each time. Not
Poor workability.

Further, since the conventional joint is opaque, the seam of the upper holder 10 cannot be seen through when it is put on the surface (outside) of the upper holder 10, and the seam is not at the center of the joint but at one end thereof. In some cases, the joint was fitted. If the offset is large, the upper holder 1 is moved from the end of the joint by the concrete casting pressure.
The concrete between 0 and the joint reaches the joint, enters the upper holder 10, and the upper holder 10 moves to lose straightness or float. In this case, the water-resistant board 6 cannot be fitted smoothly. In some cases, the joint is fitted to the back (inside) of the upper holder 10 (see FIG. 3). In this case, the center of the joint is difficult to understand because the upper holder 10 is opaque, and the seam is also offset. Problems had arisen.

The present invention has been made in consideration of the above points, and has as its object to improve the workability of the mounting structure of the upper holder and to improve the mounting accuracy.

[0009]

According to the present invention, in order to achieve the above object, the following structure, or both, or both, of the above-mentioned structure for mounting the upper holder is provided. This is the configuration that has.

The upper holder 10, the joint 30, and the fixed piece 40 are made of different colors.

The joint 30 is transparent.

The upper holder 10 is transparent.

[0013]

According to the present invention having the above-described structure, each member 10,
Since each of 30, 30 has a different color, distinction is easy. Further, the joint c of the upper holder can be confirmed through the joint 30 or the entire length of the joint 30 can be confirmed through the upper holder 10.

[0014]

[Effect] The present invention is configured as described above and performs the above-described operation, so that the following effect (a) is exhibited.

(A) Since it is easy to distinguish the members 10, 30, and 40, even an assistant can properly attach (fix) each member.
I can do it. Further, since the joint c or the entire length of the joint 30 can be visually checked, the joint c can be easily located at the center of the joint 30. Therefore, workability is improved and construction accuracy is also improved.

The upper holder 10, the joint 30 and the fixing piece 40 of this embodiment have the above-mentioned construction. First, as shown in FIG. Fix by hitting. At this time, when the head of the nail b is pressed against the raised portion 41a, the warping of the horizontal member 41 is corrected by the pressing force, and the rising piece 4
3, 43 move outward. For this reason, the fixed piece 40 and the upper holder 10
Even if the mating of the two is loose, both rising pieces 4
Due to the outward movement of 3, 43, the space between the two pieces 43, 43 expands, and the fitting strength of the upper holder 10 to the fixed piece 40 is sufficiently obtained.

Next, the upper holder 10 is fixed to the fixed piece 40.
And the upper holder 10 is connected to the joint 3 at its joint c.
0 is fitted and connected, and is provided over the entire length of the rising portion jaw 2a. At this time, due to the transparency of the joint 30,
The joint c is located at the center of the joint 30.
After that, concrete is poured into the formwork W to form the rising portion 2, and after solidification, the formwork W is removed, and the upper holder 10 is embedded and fixed to the lower surface of the jaw 2a (see FIGS. 8 to 10).

In the above-described embodiment, the joint 30 is fitted to the outside of the upper holder 10, but as shown in FIGS. 3 and 4, when the joint 30 is fitted to the inside of the upper holder 10, 10 is made transparent.
