However, in the conventional mounting structure of this type, the synthetic resin sealing material f needs to be provided along the opening b, and therefore there is a problem in that mounting is troublesome. Moreover, since it is necessary to provide the groove portion c on the top plate a, there is a disadvantage that the sink d cannot be attached to an arbitrary position on the top plate. Further, since the sealing material f is provided around one place, the watertightness may be insufficient.

The present invention has been made in view of the above circumstances, and provides a sink mounting structure having a sufficient water-tight structure and a mounting method thereof, which allows a sink to be easily mounted at an arbitrary position on a top plate. The purpose is.

[0006]

In order to achieve the above object, the first sink mounting structure of the present invention has a sink on the back surface of the edge portion of the opening provided in the top plate via a first seal member. The flange of the sink is abutted, a base material is disposed on the back surface of the flange of the sink via a second seal material, and the fixing member provided between the back surface of the base material and the back surface of the top plate is fixed to the top surface. It is fixed to a board.

According to the second sink attaching method of the present invention, when the sink is attached through the opening provided in the top plate, the first sealing material is applied to the back surface of the opening edge portion of the top plate. A first step; a second step in which the flange of the sink is pressed against the first seal material; a third step of applying a second seal material to the back surface of the flange of the sink; and the second seal Comprising a fourth step of pressing a base material toward the base material, and a fifth step of mounting a fixing member on the back surface of the base material and the back surface of the top plate and fixing the fixing member to the top plate. Is.

In the present invention, the first and second sealing materials may be any materials having water-tightness applied to the back surface of the opening of the top plate or the back surface of the flange of the sink. Silicone rubber or butyl rubber can be used.

As long as the above-mentioned base material is arranged on the back surface of the flange of the sink, piece-like ones not located on the entire surface of the flange may be arranged at intervals, but preferably the flange It is better to place it on the entire surface.
In this case, the material of the base material may be arbitrary, for example, plywood can be used.

Further, the fixing member may be a piece-like member which is provided at a distance as long as it is a plate-like member which is provided so as to extend over the back surface of the base material and the back surface of the top plate. Preferably, it has a length that closes the boundary between the base material and the top plate. In this case, the material of the fixing member may be arbitrary, and for example, a metal member such as stainless steel having corrosion resistance and rigidity can be used.

[0011]

With the above structure, the first seal member is interposed between the back surface of the opening provided in the top plate and the flange of the sink, and the second seal member is provided between the back surface of the flange and the base material. Since the sealing material of 1 is interposed, a double waterproof mechanism can be obtained. Further, by mounting the fixing member over the back surface of the base material and the back surface of the top plate which are arranged on the back surface of the flange, and fixing the fixing member to the top plate, the sink is firmly attached.
