Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching a waterproof pan to a bathroom unit, which is suitable mainly when a bathroom is provided on the second floor or higher.

In recent years, there has been a trend in single-family houses to place bathrooms on the second floor in consideration of the combined use of the entire living space. In such cases, conventional bathroom units have generally been installed by simply placing the waterproof pan of the bathroom unit on the upper floor and screwing its peripheral flange to the wall surface.

However, although this is unthinkable under normal usage conditions, due to long-term use of the bathroom or due to carelessness, the load position on the waterproof pan may cause the upper floor and the bottom of the waterproof pan (reinforcement ribs) to
This vibration can cause rattling or squeaking between the bathroom unit's waterproof pan, and the waterproofing ability of the waterproof pan, especially the drainage mass under the pan and the joints of the drain pipes, can be impaired, causing water to leak from these areas. There is a risk that the second floor floor will corrode and the first floor ceiling will become stained. Furthermore, if an unexpected accident like the one described above occurs, there is a problem in that extremely large-scale construction work is required, such as removing the bathroom unit and repairing the second floor floor and the first floor ceiling below it.

This invention was created in view of the above-mentioned drawbacks.
To provide a waterproof pan mounting structure which can be repaired not only when the waterproof pan of a bathroom unit is installed on the upper floor, but also by removing the ceiling of the lower floor without removing the waterproof pan even in the event of a water leakage accident. With the goal.

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

1 to 5 show an embodiment of the present invention, in which 1 is a steel joist (channel material). This steel joist 1 has the opening A on its side, and the receiving material 3
Both ends are fixed to the holding member 4 attached to the lower floor ceiling 20 with fixing means 2 such as bolts and nuts.
It is built on top of the. In addition, the above steel joist 1
On top is a waterproof pan 6 having reinforcing ribs 5 on the bottom.
is placed on the side surface of the reinforcing rib 5 of the waterproof pan 6, and an L-shaped hook bolt 7 having a bent portion 7a at one end and a screw 7b at the other end is mounted on the side surface of the reinforcing rib 5 of the waterproof pan 6. The reinforcing rib 5 is attached by being inserted into a hole 5a previously drilled in the side surface thereof.

The waterproof pan 6 is a removable L having a bent locking portion 8a at one end and a through hole 8b at the other end.
The central part 8c of the fixed metal fitting 8 in the shape of a letter is brought into contact with the lower surface of the steel joist 1, and the bent locking part 8a is locked inside the upper lip 1a of the steel joist 1. Screw 7b of hook bolt 7
It is fixed to the steel joist 1 by inserting it into the through hole 8b, and by screwing the nut 9 into the screw 7b and connecting it to the hook bolt 7. A spring washer 10 is attached between the nut 9 and the fixing fitting 8, so that the nut 4 can be tightened tightly. In addition, the above-mentioned fixing metal fitting 8
As shown in FIGS. 4 and 5, the bent locking portion 8a
A stepped portion 8d is formed so as to protrude to the right side so that the tip of the channel material 1 can be securely locked inside the upper lip 1a of the channel material 1.

By the way, in FIG. 1, 21 is a drainage mass provided on the bottom surface of the waterproof pan, and 22 is a drainage pipe connected to and attached to this drainage mass 22.

Next, the operation of the waterproof pan mounting structure configured as described above will be explained.

First, as shown in FIG. 1, the waterproof pan 6 is placed on the steel joist 1, and the bent part 7a of the hook bolt 7 is inserted into the hole 5a bored on the side surface of the reinforcing rib 5. 7 is locked to the reinforcing rib 5.

Next, the bending locking part 8a of the fixture 8 is inserted into the opening A of the steel joist 1, and while the center part 8c of the fixture 8 is brought into contact with the lower surface of the steel joist 1, the bending locking part 8a is placed in the opening A of the steel joist 1.
While pressing and locking the stepped portion 8d formed at the tip of the upper lip 1a on the inside of the upper lip 1a of the steel joist 1, the screw 7b of the hook bolt 7 is inserted into the through hole 8b formed at the other end of the fixture 8. The fixing fitting 8 is firmly connected to the hook bolt 7 by inserting it through and screwing the nut 9 onto the screw 7b.

Due to the above operation, the waterproof pan 6 is completely fixed to the steel joist 1, so there may be creaks or looseness between the bottom of the waterproof pan 6 and the steel joist 1 on which the waterproof pan 6 is placed. etc. will not occur. Therefore, the waterproof performance of the joint portions of the drainage mass 21 and the drain pipe 22 is not impaired, and water does not leak from these portions. In addition, in the unlikely event that a water leakage accident occurs,
Even if stains or corrosion occur on the lower floor ceiling 20, it can be easily repaired by simply removing the lower floor ceiling 20 without taking the trouble of removing the waterproof pan 6.

As explained above, the present invention involves constructing a steel joist above the ceiling of a lower floor, placing a waterproof pan on top of the steel joist, and attaching the waterproof pan to the steel joist via a removable fixture. Because it is fixed, the waterproof pan will not wobble or creak, and the waterproofing performance of the drainage mass provided under the waterproof pan and the joints of the drain pipes will not be impaired. Not only does it prevent water from leaking from any part, but even if a water leakage accident occurs, it has excellent effects such as being able to repair the accident by simply removing the ceiling of the lower floor without removing the waterproof pan. Another advantage is that the waterproof pan can normally be reliably attached to the steel joists.
