Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the installation structure of a waterproof floor pan used on the floor of a lacquer room, etc. The gist of the invention is to attach bolt receiving metal fittings 3 to a reinforcing frame 2 located south of the perimeter of a floor pan 1. , insert the adjuster bolt 5 having the rotary operation part 4 at the upper end into the bolt receiving fitting 3 so as to be able to retract freely, stand the adjuster bolt 5 on the installation surface 6, and insert the adjuster bolt 5 from the inner surface of the reinforcing frame 2. The hemming structure of waterproof floor pans is characterized by a dam plate 7 hanging vertically and slidably.

Conventionally, there have been two types of hemming structures for waterproof floor pans: a frame type and an adjuster bolt type.

The pedestal type is a method as shown in FIG. That is, the pedestals 8 are arranged on the installation surface 6 of the construction slab, the floor pan is placed on them, and the horizontal level is finely adjusted by inserting an appropriate number of liners 9 between the pedestals 8 and the floor pan 1. After that, mortar 10 was fixed. However, this method has disadvantages in that the floor pan 1 must be raised each time the bell is adjusted, which is cumbersome, and the adjustment accuracy is poor and time consuming. Further, the adjuster bolt type is a method as shown in FIG. That is, the adjuster bolts 5' are installed in advance around and in the center of the lower surface of the floor pan 1 with the rotary operation part 4' facing down.
After installing it on the hemming surface 6, the horizontal level was adjusted by rotating the adjuster bolt 5', and it was fixed with mortar 10. Although this method has better workability than the frame type, the adjuster bolt 5' is installed directly on the floor pan 1, and the adjustment of the adjuster bolt 5' in the center is difficult for the floor pan 1.
It takes a lot of work because it is located deep under the 3rd place.
As shown in the figure, at a construction site where the building slab is stepped down and the hem surface 6 is recessed, it is difficult to reach under the floor pan, making adjustment extremely difficult. The present invention has been made in view of the drawbacks of the conventional example described above, and its purpose is to easily adjust the horizontal level by turning the adjuster bolt, and to improve the adjustment of the adjuster around the floor pan. To provide a hemming structure for a waterproof floor pan that prevents the lower surface of the floor pan from being filled with mortar even when mortar is poured into a star bolt part.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings.

Reference numeral 1 denotes a floor pan, and the periphery of the floor pan 1 is stepped and provided with a flange 11.

2 is a reinforcing frame made of square tubes,
The floor pan 1 is supported by the reinforcing frame 2 with a flange 11 placed on the upper surface of the reinforcing frame 2.

Reference numeral 3 designates a bolt receiving metal fitting. The lower part 12 of the bolt receiving metal fitting 3 is fixed to the lower surface of the reinforcing frame 2 with screws 13, and the upper part 14 protrudes from the outer surface of the reinforcing frame 2. A nut 16 is welded to the lower surface of the through hole 15.

The adjuster bolt 5 is inserted into the through hole 15 of the bolt receiving metal fitting 3 and the nut 16 so as to be able to be screwed forward and backward. The reinforcing frame 2 is supported by standing the lower end of the frame 5 on an installation surface 6. It is appropriate to provide the adjuster bolts 5 at four locations. Further, the nut 16 may be separate from the upper part 14, and the upper part 14 may be placed on the nut 16 screwed onto the adjuster bolt 5. 7 is a dam plate, and a pair of vertically long holes 17 are bored in the upper part of the dam plate 7;
At 7, a screw 18 is loosely attached to a location on the inner surface of the reinforcing frame 2 facing the adjuster bolt 5, and is suspended below the lower surface of the reinforcing frame 2.

The mortar 10 for fixing the adjuster bolt 5 after adjustment is stopped by the dam plate 7 and cannot go any deeper. Further, the reinforcing frame 2 is supported by one stream of mortar. For example, the construction procedure is as follows.

First, the dam plate 7 is attached to the reinforcement frame 2 around the floor pan, but the screws 18 are not tightly tightened, but are tightened to the extent that the dam plate 7 can slide. Next, fix the bolt receiving metal fitting 3 to the reinforcing frame 2 and adjuster bolt 5.
into the bolt receiving fitting 3, and install the floor pan on the installation surface 6. Then, each adjuster bolt 5 is turned to adjust the horizontal level. The adjuster bolt 5 is the rotary operation part 4
This can be done from above even when the floor pan 1 is attached to the reinforcing frame 2, as shown in Fig. 4. With this adjustment, when the reinforcing frame 2 goes up and down, the dam plate 7 will slide up and down. become. of course,
It is also possible to make adjustments with the floor pan removed. After adjustment, mortar 10 is poured into the area of the adjuster bolt 5 to prevent damage to the adjuster bolt 5 and the movement of the floor pan due to shocks, earthquakes, etc. It will not flow to The one shown in FIG. 7 is another example of the present invention, in which a cylindrical nut-shaped bolt receiving fitting 3 as shown in FIG. 8 is built into the reinforcing frame 2 by welding in advance, and the bolt receiving fitting 3 shown in FIG. It has an adjuster bolt 5 screwed into it as shown in the figure.

After installing the floor pan 1 on the hemming surface 8, the floor pan 1 and reinforcing frame 2 are drilled above the adjuster bolts 5.
Insert a screwdriver through the through holes 19 and 20 of the adjuster bolt 5 and rotate the adjuster bolt 5 against the groove-shaped rotation operating part 4 to adjust the horizontal level. 3 is filled with caulking material 21, the through hole 19 of the floor pan 1 is closed with a cap 22, and the adjuster port 5 portion is fixed by the mortar 10'. As described above, the present invention attaches a bolt receiving metal fitting to a reinforcing frame that supports the periphery of a floor pan, and inserts an adjuster port having a rotation operation part at the upper end into the bolt receiving metal fitting so as to be able to freely screw in and out. Since it stands on the hemming surface and the dam plate is suspended from the inside surface of the reinforcing frame, the floor pan is reinforced by the reinforcing frame, eliminating the need for an adjuster bolt in the center of the floor pan, making it easier to adjust the level. In addition, the adjuster bolt is not installed directly on the floor pan, but is installed on the bolt receiving metal fitting of the reinforcing frame, and a rotary operation part is formed at the upper end, making it easy to adjust the level by raising and lowering the adjuster bolt. It has the advantage of being able to perform tasks for

Furthermore, since the dam plate is suspended from the reinforcing frame, there is an advantage that when the adjuster bolt portion is hardened with mortar, the mortar does not flow deeper than necessary into the bottom of the floor pan.
