BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower mount of a unit bus whose height can be easily adjusted.

[0002]

2. Description of the Related Art Conventionally, unit baths are manufactured in advance at a factory after a bathroom or bathtub is manufactured, carried into a construction site, assembled at the construction site, and installed in a building. In addition, it is necessary to level the floor when installing it in the building. However, the floor in the building where the unit bath is usually installed is often cast with concrete and is not evenly flat. Conventionally, as shown in FIGS. 1 and 2, an adjusting bolt c is arranged on a floor surface a via a plurality of stands b, and a reinforcing plate made of a veneer plate is provided on the adjusting bolt c on the bottom surface of a floor pan d. The horizontal beam f incorporated via e is mounted, and the floor pan d is adjusted to be horizontal by each adjusting bolt c.

[0003]

However, in the case of adjusting the height and the level of the floor pan d by adjusting a plurality of adjusting bolts c, it is necessary to put a hand or the like under the floor pan d for adjustment. Therefore, it takes a lot of time for the adjustment and the work efficiency is poor, and when the floor pan d is not level, the floor pan d is once removed, the adjusting bolt c is adjusted, and then the floor pan d is mounted again. Work is required, and there is a problem that the adjustment work requires many man-hours. Also, depending on the installation location, there are some places where the adjustment bolt c cannot be adjusted, and the adjustment bolt c near the center of the floor pan d cannot be adjusted by hand, so a special jig is required for adjustment and the cost increases. There was also a problem that it could not be applied to the inner assembly method where the bus was assembled from the inside. The present invention has been made for the purpose of remedying the above-mentioned problems, and an object of the invention is to provide a lower frame of a unit bus which can be easily adjusted.

[0004]

According to the present invention, in order to achieve the above-mentioned object, a common base having an integral structure whose height and level are adjusted by a plurality of adjustment bolts is provided on a floor surface of a unit bus installation place. A plurality of supporters are suspended from the vertical rods of the common gantry via adjustment bolts, and a floor pan is placed on these supporters.

[0005]

[Operation] With the above configuration, the height and level of the common stand can be adjusted without placing the floor pan, thereby facilitating the adjustment work, and also allowing for fine adjustment after the floor pan is placed, thereby achieving high-precision installation. Will be possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS. In FIG. 1, reference numeral 1 denotes a framed common frame, which is composed of a vertical rod 1a forming a long side and a horizontal rod 1b forming a short side, and the size is standardized according to a place where a unit bus is installed. Adjust bolts 2 are provided in the middle of the horizontal bar 1b and the vertical bar 1a of the common mount 1, respectively.
The height and the level of the common base 1 can be adjusted by adjusting the adjustment bolts 2 after the common base 1 is installed in the vehicle.

In the figure, reference numeral 4 denotes a supporter having a substantially U-shaped cross section, and a plurality of supporters arranged below the vertical rod 1a so as to be parallel to the horizontal rod 1b with the open portion facing upward. Adjust bolts 5 are provided at both ends of 4. The upper ends of these adjusting bolts 5 are inserted from below into bolt holes 1c drilled in the vertical rod 1a of the common base 1, and nuts 5a are screwed into the upper ends, and the support bolts 4 are shared by the adjusting bolts 5. It is hung on the vertical rod 1a of the gantry 1. On each of the supporters 4, a floor pan 8 in which a reinforcing plate 6 made of a plywood plate and a horizontal girder 7 made of a plurality of square pipes are previously installed is placed.

Next, the operation of the lower gantry constructed as described above will be described. First, the common gantry 1 is carried into the installation location of the unit bath, positioned at a predetermined location on the floor 3, and then shared by the adjusting bolts 2. Adjust the height and level of the gantry 1. At this time, the common base 1 has an integrated structure,
Since the adjustment bolt 2 can be adjusted without placing the floor pan 8, the adjustment operation can be easily performed in a short time. When the installation of the common gantry 1 is completed, the supports 4 are suspended from the vertical rods 1a of the common gantry 1 via the adjustment bolts 5 and the adjustment bolts 5 are adjusted so that the supports 4 have a predetermined height. The floor pan 8 is placed on the top, and in this state, the height and the level of the floor pan 8 are finely adjusted by the adjusting bolts 5 provided on the supporter 4, and the level of the common base 1 is adjusted in advance. Thus, the floor pan 8 can be easily installed horizontally. Further, since the supporter 4 on which the floor pan 8 is placed is below the vertical rod 1a of the common frame 1, it is suitable for supporting the lower part of the floor pan 8 having a height difference.

[0009]

[Effects of the Invention] As described in detail above, the present invention adjusts the height and the level of the common base, which is an integral structure, and then places the floor pan of the unit bus via the supporter. The adjustment operation can be performed in a shorter time and easier than the adjustment performed after the floor pan is installed, and there is no adjustment bolt that cannot be adjusted depending on the location. Therefore, no special jig is required for the adjustment. In addition, the height and level of the floor pan can be finely adjusted by adjusting bolts provided on the supporter, so that the floor pan and the unit bath body can be installed with high accuracy, and the inner assembly method is possible, so there are restrictions due to the wall position etc. It can be easily installed under all conditions, such as a unit bath can be installed in the place where it is received. Further, since the supporter for supporting the floor pan is located below the vertical bar of the common frame, it is suitable for supporting the bottom portion of the floor pan having a height difference at the bottom.
