Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a floor pan of a bathroom unit and a bathroom unit.

[0002]

2. Description of the Related Art As a floor pan for a bathroom unit, a rectangular bottom plate covering substantially the entire surface of a washing room and a bath room, a side wall standing all around the periphery, and a wall attached with the end of the side wall bent horizontally Conventionally, a square box-shaped floor pan, which is composed of a surface, a rising wall in which the tip of the wall-mounting surface is raised, and a number of reinforcing ribs running vertically and horizontally on the bottom surface of the bottom plate, has been widely used.

Such floor pans are bulky and heavy,
Carrying it into the bathroom space is extremely difficult. Even if it can be carried into the bathroom space, it is generally difficult to connect the drain trap under the floor pan to the drain pipe installed on the floor of the building frame and to adjust the level of the floor pan. Also, when remodeling an existing bathroom or an existing bathroom unit, it is not possible to carry the floor pan into the bathroom space, or if it is possible to carry it in, connection work and level adjustment work between the drain trap and the drain pipe installed on the floor of the building frame. In many cases, it is more difficult.

As one of the measures to solve the above-mentioned difficulties, a large opening is provided over substantially the entire floor of the floor pan washing area, and the opening is opened after the drain trap and the drain pipe are connected and the level of the floor pan is adjusted. There has been proposed a method of covering the above with a lid material or an upper floor called a "floor panel" to waterproof it (JP-A-6-177306 and JP-A-8-239881).

[0005]

When the floor pan proposed here is used, since there is a large opening in almost the entire washing area, connection between the drain trap and drain pipe under the floor pan, level adjustment of the floor pan, etc. Will be easier. Also, the floor pan body is
Because you can put your body in the opening when transporting,
It has the advantage of being easy to handle.

However, the large opening on the lower floor, on the other hand,
There is a problem that the strength of the floor of the washroom is lowered and the washroom is easily deformed when a person is put on the washroom. In order to maintain the required strength so as not to deform, it is necessary to take measures such as thickening the upper floor, providing a number of reinforcing ribs, and further strengthening the upper floor supporting portion in the lower floor, as compared with the conventional one. A groove is provided in the space between the upper floor and the lower floor (formed by the ribs and surrounding flanges) to serve as a drainage receiver when the watertightness between the upper floor and the lower floor is insufficient, and this groove is actively used. It is also used to guide the drainage. However, since such a groove is on the back of the upper floor, it is difficult to clean it, and hot water accumulates for many days and becomes unsanitary, which causes a bad odor.
Further, when the groove is provided on the wall side around the upper floor, cleaning is possible, but dirt is likely to accumulate and the appearance is not good.

The object of the present invention is to facilitate the construction such as connecting the drain trap under the floor pan with the drain pipe installed on the floor of the building frame and adjusting the level of the floor pan, and also the strength and watertightness of the floor part of the washroom. The goal is to provide floor bread that is maintained.

In order to achieve the above object, the present invention has the following constitution. That is, the present invention is a floor pan consisting of a bathtub loading area and a wash floor, or a floor pan integrally formed with the bath (floor floor for wash floor), wherein the wash floor is a wash floor lower floor 3 and an upper floor. 2 has a double structure, and the wash floor lower floor 3 has a wash floor drain 13 and a plurality of openings 4, and the upper surface of the wash floor lower floor 3 has a drain gradient toward the wash floor drain 13. The upper floor 2 is substantially flat, and the upper floor 2 is plate-shaped (that is, not a cuboid shape), and the lower surface thereof is entirely in contact with the upper surface of the wash floor lower floor 3 to cover substantially the entire upper surface of the lower floor. The lower surface of the upper floor 2 and the upper surface of the lower floor 3 of the washing place are fixed together, and four rounds (periphery) where the combined upper and lower floors and the upper surface of the lower floor are in contact with each other is a water-tight floor pan. .

In the floor pan described above, the plurality of openings 4 provided in the lower floor 3 do not necessarily have to be closed with a lid. However, in order to increase the reliability of water leakage prevention, it is preferable to seal the lid in a watertight manner.

In the floor pan described above, the drainage port 13 for the washing place
Is preferably formed near the center of one side of the washing area near the bathtub. In addition, it is preferable that both the floor 3 and the floor 2 of the washroom have a substantially concave shape in plan view (the concave portion of the concave shape serves as a drainage port). In addition, the upper surface of each of the lower floor 3 and the upper floor 2 of the washing basin is a three-sided surface with a drainage gradient from the other three sides except the one side of the washing basin close to the bathtub to the washing basin drainage port 13 (that is, drainage from two corners of the washing basin It is preferably composed of two ridge lines 6a and 6b facing the mouth or three surfaces divided by 6c and 6d.

Further, in the floor pan described above, the plurality of openings 4 of the lower floor 3 of the washing basin are one surface (that is, two openings) having a drainage gradient from one side of the opposite washing basin farthest from the washing basin drain 13 toward the drain. It is preferable to provide it on the surface surrounded by the two ridges 6c and 6d). Furthermore, two in the corner of the washing place (one in each of the two corners of the washing place), two in the vicinity of the drainage port, a total of four bolt legs. It is preferably formed within a length of the arm from the position. This is to facilitate bolt adjustment under the floor pan and piping connection / fixing work for the drain trap.
Also, it is possible to put one hand into each of the two openings and work with both hands (from both sides).

In the above floor pan, the shape of the opening 4 on the lower floor is preferably circular, and the structure for sealing the opening 4 in a watertight manner has a lid 7 for closing packings 8 sandwiched around the opening. It is possible to have a structure of tightening with the closing member 9. This seals the opening in a watertight manner. In addition, in the floor pan, the surface of the upper floor is preferably provided with a pattern (coloring, decoration, unevenness, etc.) in order to improve aesthetics and design. In addition, the back of the upper floor and the upper surface of the lower floor,
It can be firmly fixed using a bonding material.

An adhesive may be used as the joining material for fixing the upper floor and the lower floor, but preferably a structural joining tape (double-sided tape) is used. This is because there is no need to consider the curing time and the work is easy. In particular, attach the bonding tape to the back of the upper plate around the periphery and match it with the lower floor. It is more preferable to apply caulking material to the periphery.

The present invention is also a bathroom unit incorporating these floor pans.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described more specifically with reference to the accompanying drawings. FIG. 1 is a floor pan of an example according to the present invention, showing a perspective view before the upper floor is fixed to the lower floor,
FIG. 2 shows a perspective view after the upper floor is fixed to the lower floor. The floor pan 1 is composed of a bath room and a wash floor, and a wash floor 3 is provided with a wash outlet 13 near the center of one side of the wash station near the bath and a plurality of (four) rounds. A shaped opening 4 is provided. On the back side of the lower floor 3,
A bolt leg 5 is attached, and the bolt leg 5 can be rotated to adjust the level of the floor pan.

The opening 4 is used to connect the drain trap and the drain pipe (both not shown). The position of the opening 4 is preferably a position where the drain trap and the drain pipe can be connected using both hands or one hand, or the level can be adjusted by the bolt leg 5, and therefore, the connection between the drain trap and the drain pipe and the bolt leg 5 are preferable. Is preferably within the dimension of the human arm. The opening 4 is closed by using the closing lid 7. A rubber packing 8 is sandwiched around the opening 4, a disk-shaped closing member 9 is applied to the floor pan, and a flange member 10 is tightened to fix the same. At this time, if caulking is used in addition to the rubber packing 8, watertightness is further ensured. The upper surface of the lower floor 3 is
Including the closing lid 7, the drainage gradient, and the ridgelines 6c and 6d, the overall shape is approximately flat.

The upper floor 2 is an upper floor of a single plate (not a squirrel-like shape) that can cover almost the entire surface of the washing place except for the drainage port 13 of the washing place.
Concavo-convex pattern and design pattern are applied to show the design, and three downward slopes are formed from the three sides of the washroom toward the drainage port, and the boundary line (that is, the ridgeline) 6a where each surface intersects, 6b is formed. The back surface of the upper floor 2 has an overall smooth flat surface so as to be in close contact with the upper surface of the lower floor 3.

A joining material is used as a means for fixing the upper plate 2 to the lower floor 3. An adhesive may be used as the joining material, but adhesion with a (structural) joining tape 11 is preferable. This is because workability at the site is easy. The position at which the joining tape 5 is attached to the upper plate 2 is determined in consideration of the position and size of the opening 4 at the same time as it is attached to the area where it is easily warped.

In order to fix the lower floor 3 and the upper floor 2, the fitting between the lower floor 3 and the upper floor 2 can be utilized in addition to the adhesive force of the joining material. In this case, a step is formed around the lower floor 3 in accordance with the size of the upper floor 2, one side is aligned with the upper floor 2 and the lower floor 3, and the upper floor 2 is directly aligned with the lower floor 3. Easily glued and fixed. As for the watertightness between the upper floor 2 and the lower floor 3, such adhesion and fixing are sufficient, but the upper floor 2
It is even more reliable to further finish the area around with caulking material. At this time, it is efficient if it also serves as a caulking finish on the lower end of the wall panel.

FIG. 3 is the upper floor of another example according to the present invention. The boundary between the washing room and the bathtub (side gutter) is also integrally formed on one side of the upper floor.

A bathroom unit incorporating the floor pan of the present invention is assembled, for example, as follows. Grasp the opening of the floor pan (lower floor) 3, one of which is a washing room and the other of which is a bathtub basin, and this is carried and carried into the bathroom space. An adjusting member (floor leg bolt) 5 whose height can be adjusted is provided on the back surface of the floor pan (lower floor) 3. Floor pan washing place Before placing the upper floor 2 on the lower floor 3, the drain trap under the floor pan and the drain pipe installed on the floor surface of the building frame are connected and the level of the floor pan is adjusted. After that, a wall panel, a door frame, a door frame, and a door are erected around the floor pan, a beam escape cover is provided at a portion facing the protrusion of the ceiling beam, and a ceiling cover is provided at an upper portion. At this point, again adjust the floor pan level and check the verticality of the door. At this time, if it is not horizontal or vertical, the bolt leg 5 is adjusted again from the opening 4 of the lower floor 3 to correct the whole. Then, the upper floor 2 is placed on the lower floor 3 and bonded with a bonding material. In addition, a bathtub will be placed and fixed, and other facilities such as a bathroom counter, water supply device, hot water supply device, shower device, lighting device, and ventilation device will be installed to form a bathroom unit.
