Description

[Detailed description of the invention] [Technical field] The present invention relates to a structure for attaching a drainage device to a floor surface with a decorative sheet pasted to the floorboard, and provides a structure for easily closing the hole edges of the decorative sheet to be pasted later. Regarding the technology to be used.

[Background Art] Conventionally, for example, drainage equipment that connects a drainage hose from a washing machine and drains laundry wastewater into the sewer system requires more work than pasting decorative sheets, which is included in the finishing work, due to plumbing work, etc. Previously done result, 8th
As shown in the figure, the mounting locking edge 5 of the device main body 3 is mounted and locked on the floorboard 1, and the hole edge 2a of the decorative sheet 2 cannot be closed. As shown, a gap d is created between the mounting locking edge 5 and the hole edge 2a, and dirt accumulates in this area, resulting in problems such as deterioration of the appearance and peeling of the hole edge 2a.

[Purpose of the invention] The present invention was created in view of the above problems, and its purpose is to create a floor surface on which the edges of holes in decorative sheets can be easily closed by simple improvements. The objective is to provide an installation structure for drainage equipment.

[Disclosure of the invention] The structure for attaching a drainage device to a floor surface according to the present invention is a structure for attaching a drainage device to a floor surface in which a decorative sheet 2 is pasted on a floorboard 1, and a drainage hose can be inserted therein. A mounting locking edge 5 that is mounted and locked on the upper surface of the floor plate 1 around the mounting hole 4 formed in the floor surface 1 is formed on the outer periphery of the instrument body 3, and from this mounting locking edge 5. It is further characterized in that a sheet pressing locking edge 6 is formed on the outer periphery of the decorative sheet 2, into which the hole edge 2a of the decorative sheet 2 is pushed and which presses and locks the hole edge 2a against the floorboard 1. With this configuration, the above object has been achieved. In other words, the installation locking edge 5 formed on the outer periphery of the instrument body 3
Further, the hole edge 2a of the decorative sheet 2 is located on the outer periphery.
By forming a sheet pressing locking edge 6 that presses and locks the hole edge 2a against the floorboard 1, the appliance main body 3 is attached to the upper surface of the floorboard 1 around the mounting hole 4 of the floorboard 1. The installation locking edge 5 is installed and locked and the appliance body 3 is constructed, and then the hole edge 2a of the decorative sheet 2 pasted on the floorboard 1 is placed below the sheet pressing locking edge 6 of the appliance body 3. By pushing the hole edge 2a under the sheet pressing locking edge 6, the simple improvement of forming the sheet pressing locking edge 6 on the outside of the mounting locking edge 5, This allows the hole edges 2a of the decorative sheet 2 to be easily closed.

Embodiments of the present invention will be described in detail below based on the drawings.

Drainage device B is constructed as a drainage trap, and its main body 3 is a molded product of synthetic resin, and a flange 8 having a substantially square outer shape is integrally formed at the upper end of a cylindrical outer tube 7. A connecting portion 9 is protruded inward from the upper and lower intermediate portions of the inner surface of the outer cylinder 7, and the collar portion 13 of the trap member 12, which connects the trap inner cylinder 10 and the trap outer cylinder 11 at the appropriate connecting portion, is connected to the connecting portion. 9 is connected with an airtight packing 14 interposed therebetween. In order to connect the trap member 12 to the connecting portion 9, various design changes are possible, such as a simple mounting form, a screwing form, etc.

The trap inner tube 10 of the trap member 12 extends upward, and this extending portion serves as a connection port 16 for a drain hose from a washing machine, for example, and the lower end of the trap inner tube 10 is open. The trap outer cylinder 11 is formed in a bowl shape outside the trap inner cylinder 10, the lower end of the trap outer cylinder 11 is closed, and trap drainage ports are provided at appropriate intervals in the circumferential direction at the upper end of the trap outer cylinder 11. 15 is formed. Therefore, the drain from the washing machine, etc., from the drain hose (not shown) connected to the connection port 16 is trapped in the inner and outer cylinders 1.
Water can be drained from the bottom opening 18 of the outer cylinder 7 of the instrument main body 3 to the sewage through a trap 17 formed between 0 and 11.

The trap member 12 includes a trap inner cylinder 10.
Place the baffle plate 19 between the trap outer cylinder 11 and the trap 1.
7 to prevent odor from the trap drain port 15 from flowing back through the perforated plate 20 formed in the trap member 12. In this way, the backflow of odor from the trap drain port 15 is prevented on both the trap inner cylinder 10 side and the perforated plate 20 side.

On the back surface of the base of the flange 8, a substantially square mounting locking edge 5 is made to protrude downward.
This mounting locking edge 5 is stably mounted and installed on the surface of the floorboard 1 around a substantially square mounting hole 4 formed in the floorboard 1. Small mounting holes 21 are formed in the four corners of the flange 8, and screws or the like are inserted into the small mounting holes 21 so that the drainage device B can be mounted on the floorboard 1.

The hole edge 2a of the decorative sheet 2 is pushed further into the outer periphery of the back surface of the flange 8 than the installation locking edge 5 formed at the base of the back surface of the flange 8, and the hole edge 2a is pressed against the floorboard 1 and locked. A sheet pressing locking edge 6 is formed. Then, attach the drain device B to the floorboard 1 with screws, etc., and install the drain device B.
After completing the piping work in which the sewage pipe (not shown) is connected to the piping connection tube 22 at the bottom of the floor plate 1, when attaching the decorative sheet 2 to the floor plate 1, cut it to a diameter slightly larger than the installation hole 4 of the floor plate 1. As shown in FIG. The hole edge 2a is closed by inserting the sheet into the hole by using the elasticity of the sheet pressing locking edge 6.
In such a case, the end surface of the hole edge 2a is brought into contact with the mounting locking edge 5. During such construction, it is preferable to make a notch 23 at the corner of the hole edge 2a as shown in FIG. 7.

Note that the shapes of the mounting locking edge 5 and the sheet pressing locking edge 6 can be modified in various designs other than those shown in FIG. 4.

[Effects of the invention] In short, the present invention has the effect that the hole edge of the decorative sheet is pushed further into the outer periphery than the installation locking edge formed on the outer periphery of the device body, and the hole edge is pressed against the floorboard and locked. Since the sheet pressing locking edge is formed, the mounting locking edge of the appliance body is installed and locked on the upper surface of the floorboard around the mounting hole of the floorboard, and the appliance body is installed. By pushing the hole edge of the decorative sheet pasted onto the device body below the sheet pressing locking edge, the hole edge can be slipped under the sheet pressing locking edge, that is, the mounting locking edge. A simple improvement of forming a sheet pressing locking edge on the outside of the decorative sheet has the advantage that the hole edge of the decorative sheet can be easily closed.
