Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to so-called floor pans such as a bathtub-mounted floor pan and a bathtub-integrated floor pan.

(Prior Art) Conventionally, a floor pan is provided such that a partition wall forms a recess on the upper side at a bathtub mounting portion or a boundary portion between the bathtub portion and the washroom portion.

(Problems to be solved by the invention) Since such a floor pan has only the bathtub placement section or the bathtub section and the washroom section connected continuously through the partition wall, after the floor pan is removed from the mold. The resin shrinkage causes the two halves to flex and deform toward the back side so that they approach each other around the partition wall, which causes the yield to deteriorate.

In addition, the partition wall may be deformed or damaged due to vibration or load during transportation or use, and there is a problem in work that requires careful handling.

Therefore, it can be proposed that an inclusion be placed horizontally between the back sides of the partition walls.

However, in order to prevent flexural deformation due to resin shrinkage, an intervening material is laid across the back wall of the partition wall during floor pan formation. Durability is reduced and inclusions are not fixed securely. There is a risk that it will fall out due to the repeated action of beckoning due to long-term use.

The present invention has been made in view of the above-mentioned conventional circumstances, and its technical problem is to deform a partition wall by installing a reinforcing mechanism that is the same body as the floor pan main body between the legs so as to straddle the rear side of the partition wall. Is to prevent it effectively.

(Technical Means) The technical means taken to achieve the above-mentioned purpose is that a leg portion is projected on the back side of both halves along a partition wall formed at the boundary between one half and the other half. In the floor pan, a reinforcing member that is wide in the length direction of the leg portion is installed obliquely across the leg portions of both half parts, and the reinforcing member and the floor pan body are integrally molded. Use as a summary.

(Operation) According to the above technical means, the reinforcing member that is installed across the leg strips across the space behind the partition walls in both half portions of the floor pan body increases the connection area with the leg strips. Integrally integrated with the floor pan body.

(Effect of the Invention) As described above, according to the present invention, the reinforcing member which is installed between the leg portions across the space behind the partition walls of both half portions of the floor pan body is integrally formed with the floor pan body, Moreover, since the connecting area (mounting area) with the leg portions is long and wide, the floor pan main body and the reinforcing member are stably and firmly connected to each other.

Therefore, stress concentration on the partition wall portion due to the resin shrinkage force of the floor pan and the load load during transportation and use is eased, the partition wall is not distorted, and it is excellent in durability that does not bend and deform. We can provide the floor bread.

Moreover, when the reinforcing member is integrally molded with the floor pan body, the reinforcing member is laid down sideways with one end abutting on the base of the one leg part (one half leg part) and the floor pan body. Then, the other end obliquely contacts the other leg portion (the leg portion of the other half).

Therefore, it is very easy to position the reinforcing member between the leg portions, and it is possible to surely install the floor pan body by absorbing the molding error of the floor pan body and the dimensional error of the floor pan body, and the productivity of the floor pan can be greatly improved. .

(Example) Next, the Example of this invention is described based on drawing.

FIG. 1 shows a plan view of a bathtub floor floor pan.

The floor bread main body (A) is a bathtub placing type floor pan having a bathtub placing part (1) in one half and a washing place part (2) in the other half, and has a partition wall (100) at the center. And a wall-mounting surface (3) is provided around the periphery.

As shown in Fig. 1, the partition wall (100) has a drainage port (4) at one end of the central area. Therefore, except for this drainage port (4), the partition wall (100) is raised one step over the entire width. It is set up.

On the back side of this partition wall (100),
A reinforcing member (B) is installed so as to extend over the washing area (2).

The reinforcing member (B) is obtained by covering the plywood (b ₁ ) with the FRP layer (b ₂ ), and the back side of the floor pan body (A) from the bathtub placing part (1) and the washing part (2). The leg portion (5) closest to the leg portion (5) protruding along the partition wall (100)
(5) The floor pan body (A) is formed to be longer than the interval and wide in the length direction of the leg section (5), and is installed obliquely between the leg sections (5) and (5). ) Is integrally molded.

In this embodiment, the reinforcing member (B) is as shown in FIG. 2 during the molding process of the floor pan body (A) by the hand lay-up method, that is, when the FRP layer on the molding die is in a semi-cured state. One of the leg portions (5) (5) is brought into contact with one of the base portions of the floor pan main body (A), and the other end is naturally brought into contact with the other leg portion (5) by lying sideways. By contacting the middle part of the floor pan and waiting for the floor pan body (A) to harden and then removing from the mold, the legs (5) are connected (joined) to the resin parts (a ₂ ) (b ₂ ) in the same body. ) (5) is fixed.

When the reinforcing member (B) is installed over the leg portions (5) and (5) in the molding process of the floor pan body (A) as described above, the floor pan body (A) is temporarily slightly removed after the mold release. Even if contracted and deformed, the contracted deformation of the resin is not concentrated on the partition wall (100).

In this embodiment, the erected position of the reinforcing member (B) is, as shown in FIG. 1, a partition wall (100) on the side opposite to the drain port (4).
It is on the back side of the part.

In addition, in this embodiment, although the bathtub-mounted floor pan is described in detail, the bathtub-integrated floor pan is also targeted.
