Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a waterproof floor pan forming the floor of a bathroom.

[Conventional technology]

A bathroom unit is formed by assembling a waterproof floor pan, a wall panel, and a ceiling panel.The waterproof floor pan that makes up the floor of the bathroom unit has a bathtub mounting area for installing a bathtub, and a washing area. It is formed by a washing area that serves as a floor. Conventional waterproof floor pans are made of FRP, stainless steel, or the like, with a bathtub mounting part and a washing area integrally formed.

[Problem to be solved by the invention]

However, when a waterproof floor pan is formed by integrating the bathtub mounting part and the washing area in this way, the whole becomes large, which makes manufacturing difficult and makes it difficult to carry it to the construction site and install it. In particular, as the overall size increases, it becomes difficult to align the drainage part formed in the waterproof floor pan with the drainage piping, resulting in poor workability in terms of piping connections. In addition, there are two types of waterproof floor pans: a stationary type in which the bottom of the bathtub and the washing area are formed at the same level so that the bottom of the bathtub is almost at the same level as the washing area, and a stationary type in which the bottom of the bathtub is located below the washing area. There are two types of semi-recessed bathtubs, in which the bottom of the bathtub resting part is formed at a lower level than the bottom of the washing area, and the washing area can also be decorated with various colors and patterns to suit the preferences of users. Ru. Therefore, the combination of the two types of models and the different colors and patterns of the washing area will result in a wide variety of variations, and as the types of products increase, the number of types used in manufacturing will also increase, leading to lower manufacturing costs. There is also the problem that it becomes expensive. The present invention has been made in view of the above points, and is a waterproof floor pan for a bathroom that can be manufactured in a smaller size and at a lower manufacturing cost, and in addition, the drainage section can be easily constructed. The purpose is to provide the following.

[Means to solve the problem]

The waterproof floor pan for a bathroom according to the present invention has a bathtub mounting pan 1 for installing a bathtub and a washing area pan 2 that are formed separately, and a drainage part 6 is provided in the bathtub mounting pan 1. An engaging recess 3 that opens upward is provided along the edge of the washing area pan 2, and an engaging piece 4 that projects downward is provided along the edge of the washing area pan 2. This is characterized in that the space between the engaging piece 4 and the engaging recess 3 is sealed by a waterproof material 5 which is inserted into the engaging recess 3 and filled into the engaging recess 3.

[Effect]

In the present invention, since the bathtub-mounted pan 1 and the washing area pan 2 are separate bodies, each can be manufactured and handled separately in a small size.

【Example】

The present invention will be explained in detail below using examples. As shown in FIG. 2, the bathtub mounting pan 1 is provided with rising parts 9 on three sides of the outer periphery, and a panel receiving piece 10 for attaching the lower end of the bathroom wall panel to the upper end of the rising part 9. A rising part 11 for forming a step is provided on the other side, and a bending piece 12 having a substantially U-shaped cross section is provided at the upper end of the rising part 11 for forming a step, and the bending piece 12 is opened upward. An engagement recess 3 is formed. Also, the bathtub mounting pan 1
A drainage portion 6 is provided extending from the end of the side on which the bent piece 12 of the saw is provided. The bottom surface of the drain section 6 is formed as a continuous surface with the bottom surface of the bathtub mounting pan 1, and a drain trap box 13 is attached to the bottom surface of the drain section 6. The above-mentioned engagement recess 3 is this drainage part 6
It is also formed continuously on the edge of the . In FIG. 2a, reference numeral 14 designates a mounting base on which the legs of the bathtub are placed, and reference numeral 15 designates a concave surface portion that guides the water in the bathtub mounting pan 1 to the drainage portion 6. Here, since the bathtub mounting pan 1 is hidden by placing the bathtub on it, the appearance finish is not so important, and a high level of color finish such as coloring is not required, and the defect rate is low. becomes significantly smaller. Further, as shown in FIG.
6 is provided with a panel receiving piece 17 for attaching the lower end of the bathroom wall panel, and a partition rising part 18 is provided on the other side of the outer periphery. An engagement piece 4 is provided so as to protrude toward the front. Further, a notch 19 is formed at the end of the side of the wash area pan 2 on which the engaging piece 4 is provided, and the engaging piece 4 is also formed continuously at the edge of this notch 19. be. The bathtub mounting pan 1 and washing area pan 2 are each manufactured separately, and although they may be integrated in a factory to form a waterproof floor pan, they are generally constructed separately. Deliver to the site. Therefore, the bathtub mounting pan 1 and the washing area pan 2 can be easily transported to the construction site by one person in a small-sized divided state, and construction can be carried out even in the case of extensions and renovations that have many restrictions. At the construction site, the bathtub mounting pan 1 is first installed on the floor substrate, and when the bathtub mounting pan 1 is installed in this way, the box 13 of the drainage section 6 is connected to the drainage pipe. Since the bathtub mounting pan 1 is small in size, it is possible to easily align the drainage part 6 and the drainage piping, etc., and the connection with the piping is facilitated. Because it protrudes from the end of the bathtub mounting pan 1,
It is possible to reliably connect the pipes while visually checking the connection status. After the bathtub mounting pan 1 is attached to the floor substrate in this way, the washing area pan 2 is installed on the floor substrate, and at this time, as shown in FIG. Insert and engage the engaging piece 4 of the washing area pan 2 to connect and integrate the bathtub mounting pan 1 and the washing area pan 2,
It forms the waterproof floor pan that makes up the bathroom floor. The engaging recess 3 is filled with a waterproof material 5, and this waterproof material 5 ensures waterproofing between the engaging recess 3 and the engaging piece 4 over the entire length. be. As the waterproofing material 5, a hardening resin such as a silicone resin liquid can be used.
After pouring this silicone resin liquid, insert the engagement piece 4 into the engagement recess 3, and by curing the silicone resin liquid in this state, the waterproof material 5 made of cured silicone resin will be engaged. This is to ensure waterproofing between the mating recess 3 and the engaging piece 4.
Since the engaging recess 3 is formed as a groove that opens upward, it can be waterproofed with the waterproofing material 5 formed by pouring a liquid into it and hardening it, and even an amateur can do so safely. Waterproofing construction can be carried out reliably with care. When using a silicone resin liquid, it is preferable to use a one-component type silicone resin liquid with good fluidity. In addition, when connecting the bathtub-mounted pan 1 and the washing-place pan 2 in this way, the drainage part 6 of the bathtub-mounted pan 1 is connected to the washing-place pan 2.
It is fitted into the notch 19 of. The waterproof floor pan formed by connecting the bathtub mounting pan 1 and the washing area pan 2 as described above is installed on the floor base, and then the bathtub is placed on the bathtub mounting pan 1 and set. At the same time, the bathroom can be assembled by attaching wall panels, ceiling panels, etc., and further installing internal fixtures. The embodiment shown in FIG. 1 constitutes a semi-embedded waterproof floor pan in which the bottom of the bathtub mounting pan 1 is formed deep so that the bottom of the bathtub placed on the bathtub mounting pan 1 is lower than the washing area pan 2. However, by using the bathtub mounting pan 1 having a shallow bottom without providing the rising part 11 for forming a step, the bottom of the bathtub placed on the bathtub mounting pan 1 can be used as a washing area. It is possible to construct a stationary waterproof floor pan as shown in FIG. 6, which is at almost the same level as the pan 2. In this way, a semi-embedded type waterproof floor pan and a stationary type waterproof floor pan can be formed by using a common shape as the washing area floor pan 2. In addition, the wash area pan 2, which stands out as the floor of the bathroom, is available in various colors and patterns to suit the needs of users.
A wide variety of items with uneven patterns are prepared, and if the washing area pan 2 and the bathtub placement pan 1 are integrated, these various types are required for each of the semi-embedded type and the stationary type. However, if the pan is divided into the bathtub pan 1 and the washing area pan 2 as in the present invention, this is not necessary, and there are fewer types of molds during manufacturing. It's over. In addition, the hot water overflowing from the bathtub can be removed using the bathtub mounting pan 1.
Of course, the water is drained from the drainage section 6 provided in the
The hot water in the washing area pan 2 also flows from the washing area pan 2 to the drainage section 6.
and is drained away. In both the semi-embedded type and the stationary type, the bottom of the bathtub-mounted pan 1 is never higher than the bottom of the washing area pan 2, so by providing a drainage section 6 on the side of the bathtub-mounted pan 1, Drainage can be carried out without the need to provide a drainage section in the washing area pan 2. Here, the drainage part 6 provided in the bathtub mounting pan 1 is
Since the drain portion 6 is formed to protrude from the end toward the washing area pan 2 side, the drain portion 6 is not hidden by the bathtub placed on the bathtub placement pan 1, and the drain portion 6 is provided on the bathtub placement pan 1. Despite this arrangement, maintenance and inspection of the side of the washing place pan 2 or the drainage section 6 can always be easily carried out.

【Effect of the invention】

As described above, in the present invention, the bathtub mounting pan and the washing area pan for installing a bathtub are formed separately by dividing the waterproof floor pan, so that the bathtub mounting pan and the washing area pan are separated. Each can be manufactured and handled separately in a small size, reducing manufacturing costs and improving workability. Many types of waterproof floor pans can be formed by combining pans. In addition, a drainage part is provided in the bathtub placement pan, an engagement recess that opens upward is provided along the edge of the bathtub placement pan, and an engagement piece that protrudes downward is provided along the edge of the washing area pan. , the engagement piece is inserted into the engagement recess and engaged, and the waterproof material filled in the engagement recess seals between the engagement piece and the engagement recess.
Waterproofing can be achieved using a waterproofing material that is formed by pouring a liquid into an engaging recess formed as a groove that opens upward and allowing it to harden. Even an amateur can carry out waterproofing work with peace of mind. Furthermore, the bathtub placement pan and the washing area pan are installed by first installing the bathtub placement pan, and then installing the washing area pan while engaging the engagement piece in the engagement recess of the bathtub placement pan. Therefore, when connecting the drainage part to the drainage pipe, the bathtub mounting pan can be installed while aligning the drainage part provided on the bathtub mounting pan with the drainage pipe prior to the washing pan. This makes it easier to align the drainage part and the drainage pipe.
