Description

  The present invention relates to an apron mounting structure in which right and left end edges of an apron supported by a weir portion of a washing basin pan and a flange portion of a bathtub are watertightly attached to a wall panel rising from the washing basin pan.

  2. Description of the Related Art Conventionally, a bathroom unit is known in which parts such as a bathtub, a floor pan, a wall panel, and a ceiling panel are preliminarily molded at a factory, and the molded parts are brought into the field before being assembled.

  The bathroom unit is simpler to construct than the conventional bathroom where tiles are attached one by one on the site and finished. The construction period can be shortened, and the number of parts is reduced compared to the conventional bathroom. Since the cost can be reduced, it is widely used.

  However, since the bathroom unit has a structure in which the space formed between the washing pan and the bathtub is covered with an apron, it must be devised so that the apron is damaged and the hot water at the time of bathing is not flooded.

  Therefore, conventionally, a fixing member is bridged between the weir portion of the washing pan and the flange portion of the bathtub, so that the load of the bather on the flange portion of the bathtub is received by the fixing member so as not to reach the apron. An apron mounting structure has been proposed (for example, Patent Document 1). As a result, the problem of the bathroom unit described above has been greatly improved by the structure of Patent Document 1 previously proposed.

  However, in the bathroom unit, not only the watertightness of the apron but also the beautiful finish inside the bathroom is required in the market. Therefore, the bathroom unit is designed so that the joint portion formed between the members is blocked by the joint material so that the joint portion is prevented from being flooded and the finish of the joint portion is beautiful.

  Therefore, conventionally, a method of filling a joint portion with a paste-like silicon caulking agent (wet joint material) and curing it has been performed. However, in the method using a wet joint material, the filled silicon caulking agent tends to become uneven (unevenness), and the joints may be imperfectly watertight, resulting in poor appearance. Therefore, the filling of the silicon caulking agent requires a high level of operator skill.

  The silicon caulking agent takes at least 12 hours from filling to curing. Therefore, even when the construction is finished, the owner cannot use the bathroom unit immediately and is inconvenienced.

  Furthermore, since the silicon caulking agent is likely to be displaced by receiving some external force before it is cured, it tends to cause cracks. As a result, the watertightness of the joints becomes incomplete, which may cause a water leakage accident.

  Therefore, instead of a structure using a wet joint material, conventionally, a dry joint material formed of a resin such as polyethylene, polypropylene, vinyl chloride, fluorine resin, or silicone resin on a joint part formed between adjacent members. A structure has been proposed in which the edge of the member is sandwiched and fixed by a joiner together with a dry joint material (for example, Patent Document 2).

JP2011-15910A JP-A-2005-9203

  However, in the structure of patent document 2 proposed previously, although members can be connected via a dry joint material, it is not the structure which connects a member so that a load may not be applied to an apron. For this reason, in attaching the apron, apart from the structure described above, there is a demand in the market for a structure that supports the apron so that no load is applied to the apron and connects to other members via a dry joint material.

  The present invention has been made in view of such circumstances, and a fixing member is provided that is folded between the edge of the apron side and the wall panel is folded between the weir portion of the washing pan and the flange portion of the bathtub. The left and right end edges of the apron are supported, and an overhang is formed to project from the supporting point to the washing pan side and to form a gap for sandwiching the bent portion of the wall panel between the left and right end edges of the apron. By sandwiching a folded portion of the wall panel between the folded portion of the wall panel and the left and right edge portions of the apron, and inserting a dry joint material having a substantially wedge shape in plan view into the joint portion. An object of the present invention is to provide an apron mounting structure capable of connecting an apron and another member via a dry joint material while supporting the apron so that no load is applied thereto.

  The apron mounting structure according to the present invention is an apron mounting structure in which the left and right edge edges of the apron supported by the weir part of the washing place pan and the flange part of the bathtub are watertightly attached to the wall panel rising from the washing place pan. The wall panel includes a bent portion that bends along an edge on the apron side, and is supported between the weir portion of the washing basin pan and the flange portion of the bathtub to support the left and right edge portions of the apron. And a fixing member that includes a protruding portion that protrudes from the support portion to the washing pan side and forms a gap that sandwiches the bent portion of the wall panel between the left and right edge portions of the apron. The joint portion formed between the bent portion of the wall panel sandwiched between the gaps of the members and the left and right end edges of the apron is closed by inserting a dry joint material having a substantially wedge shape in plan view. Features .

In the present invention, the wall panel is provided with a bent portion that bends along the edge on the apron side, so that the bent portion becomes a portion that engages with the apron.
Moreover, a fixing member receives the bather's load concerning the flange part of a bathtub, when a fixing member is spanned between the weir part of a washing-room bread, and the flange part of a bathtub.
Moreover, a fixing member supports the apron by providing the support part which supports the right-and-left edge part of an apron.
In addition, the fixing member includes an overhanging portion that protrudes from the support portion toward the washing pan and forms a gap that sandwiches the bent portion of the wall panel between the left and right edge portions of the apron, so that the fixing member The apron and the wall panel are connected to each other by sandwiching the bent portion of the wall panel between the end edges.
Further, the joint portion formed between the bent portion of the wall panel sandwiched between the gaps of the fixing member and the left and right edge portions of the apron is blocked by the dry joint material, thereby preventing water from entering the joint portion. At the same time, the appearance design of the joint is ensured.
Further, since the dry joint material inserted into the joint part is substantially wedge-shaped in plan view, the bent portion of the wall panel is pressed to the protruding portion side of the fixing member according to the insertion depth of the dry joint material. It is sandwiched between the overhang and the dry joint material.

  Further, the apron mounting structure according to the present invention is such that the apron has a notch-facing engagement portion provided on the bathtub-side surface, and the notch of the engagement portion is provided on the bathtub-side in advance. You may comprise so that it may engage with the axial part of the volt | bolt made.

  In the present invention, since the bolt that receives the engaging portion of the apron is attached to the bathtub side, the bolt can be prevented from dropping and being lost during the operation.

  In the present invention, the apron and other members can be connected via the dry joint material while supporting the apron so that no load is applied.
