状にライニングすることである。The technical means of the present invention is to mold a tank portion having a cross-sectional shape having a concave step portion that is open at the upper edge and upward and inward of the tank.
On the outer surface of the tank portion, a reinforcing material having a deformed portion molding surface continuous to the rising surface of the recessed step portion is fixed, and a resin layer is formed on the deformed portion molding surface starting from the inside of the recessed step portion and the surface of the tank portion. The lining is to be flush.
次に、本発明の実施例を図面に基づいて説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.

が槽部（a1）と共に一体成形できない（脱型不能）形状
である為、本発明製造方法を用いて製造する。The bathtub (A) in this embodiment is an apron section (2).
Since it has a shape that cannot be integrally molded with the tank portion (a 1 ) (unmoldable), it is manufactured using the manufacturing method of the present invention.
まず、第１工程は異形部（a2）（エプロン部（２），
ヘッドレスト（１）（１），エプロン部（２）と対向す

It has a three-layer structure of a backup layer (8) made of an acid resin (resin for general lamination).
第２工程は上記槽部（a1）の外面に凹段部（５）の立
上がり面（５′）に連続する異形部（a2）の成形面
（９）（10）（11）を有する補強材（a3）を固定する工
程である。The second step has the molding surfaces (9), (10) and (11) on the outer surface of the tank portion (a 1 ) of the deformed portion (a 2 ) continuous with the rising surface (5 ′) of the concave step portion (5). This is the step of fixing the reinforcing material (a 3 ).

介して前記の通り槽部（a1）外面に固定する。The reinforcing material (a 3 ) is made of a foaming material such as urethane foam, and the apron molding surface (9), headrest molding surface (10), and upper edge molding surface (11) are formed on the surface by cutting. It is composed of several blocks, and is fixed to the outer surface of the tank (a 1 ) via the adhesive (12) as described above.
第３工程は、上記成形面（９）（10）（11）及び凹段
部（５）内に樹脂層（a4）ライニングによって形成する
工程である。The third step is a step of forming a resin layer (a 4 ) inside the molding surfaces (9), (10) and (11) and the concave step portion (5).
樹脂層（a4）は前記槽部（a1）の構成用として使用さ
れたFRP層（７）と、ゲルコート層（６）との２層構造
とする。The resin layer (a 4 ) has a two-layer structure of a FRP layer (7) used for the constitution of the tank part (a 1 ) and a gel coat layer (6).
FRP層（７）は前記凹段部（５）内から夫々の成形面
（９）（10）（11）終端に至るまで第１層目としてライ
ニングし、脱泡して成形する。The FRP layer (7) is lined as the first layer from the inside of the stepped portion (5) to the ends of the respective molding surfaces (9), (10) and (11), and is defoamed and molded.
ゲルコート層（６）は上記FRP層（７）が硬化した
後、FRP層（７）上を槽部（a1）表面のゲルコート層
（６）と面一となるようにライニングして槽部（a1）の
そのゲルコート層（６）と連設せしめ、更に均して継目
がないように一体化し、異形浴槽として供する。After the FRP layer (7) is cured, the gel coat layer (6) is lined on the FRP layer (7) so as to be flush with the gel coat layer (6) on the surface of the tank portion (a 1 ). The gel coat layer (6) of a 1 ) is continuously provided, and the gel coat layer (6) is further evenly and integrally formed so as to be used as a deformed bath.

る。In this Example, the reason why the modified portion (a 2 ) has a two-layer structure of the FRP layer (7) and the gel coat layer (6) is that the reinforcing material (a 3 ) has a backing reinforcement function, This is because the strength is sufficiently retained even if 8) is not intentionally provided, but it is optional even if the strength is further imparted by forming a three-layer structure including the backup layer (8) like the tank portion (a 1 ). Is.
本発明は以上のように、上端縁に上方及び槽内方向を
開放した凹段部を有する断面形状の槽部を型成形し、

形部成形面を有する補強材を固定し、上記凹段部内を始
端として異形部成形面に樹脂層を前記槽部の表面と面一
状にライニングするので下記の作用効果がある。As described above, the present invention molds a tank portion having a cross-sectional shape having a concave step portion that is open at the upper end and upward and inward of the tank.
On the outer surface of the tank portion, a reinforcing material having a deformed portion molding surface continuous to the rising surface of the recessed step portion is fixed, and a resin layer is formed on the deformed portion molding surface starting from the inside of the recessed step portion and the surface of the tank portion. Since the lining is flush, the following operational effects are obtained.
型成形された槽部外面に、異形部の成形面を有する
補強材を固定する工程と、その成形面上に樹脂層をライ
ニングによって形成する工程の２工程で異形浴槽が製造
される。A deformed bath is manufactured by two steps, namely, a step of fixing a reinforcing material having a molding surface of a deformed portion to the outer surface of the molded tank portion and a step of forming a resin layer on the molding surface by lining.
故に旧来のように槽部と異形部とを夫々専用型で型成
形する工程と、槽部，異形部両者を接合する工程と、裏
打補強材を架設する工程の３工程を逐次実施する技術に
比べて製造工程が簡略化し、手間がかからない。Therefore, the technology of sequentially performing three steps of the conventional process of molding the tank portion and the deformed portion with dedicated molds, the step of joining both the tank portion and the deformed portion, and the step of installing the backing reinforcement material Compared to this, the manufacturing process is simplified and less labor is required.
補強材は予め異形部の成形面を有するから、異形部
裏面と槽部裏面との間全面に渉って充填されることにな
る。Since the reinforcing material has a molding surface of the deformed portion in advance, the reinforcing material is filled over the entire surface between the rear surface of the deformed portion and the rear surface of the tank portion.
故に部分的に補強材を架設した旧来の異形浴槽に比し
て異形部分の耐強度も増強し、より耐久性に秀でた異形
浴槽を製造できる。Therefore, the strength of the deformed portion is enhanced as compared with the conventional deformed bathtub in which the reinforcing material is partially installed, and a deformed bathtub having more excellent durability can be manufactured.
依って、所期の目的を達成できる。 Therefore, the intended purpose can be achieved.
