A drain trap assembly structure is provided to easily install and replace a connecting pipe by manufacturing the connecting pipe and the catch basin as separate parts, and to prevent the connecting pipe from being upwardly separated by forming separation prevention ribs. A drain trap assembly structure comprises a hollow catch basin having upper/lower openings wherein a lower layer wide diameter drain pipe is connected to the lower opening and waste water is drained through the upper opening. Plural supporting ribs(101) are formed on the outer part of a connecting pipe(100) and are adhered closely to support the inner side of the catch basin. The supporting pipe is positioned at the center of the lower opening wherein upper small diameter pipe is connected to the upper end and on the lower end lower small diameter pipe is connected. The connecting pipe is formed to be combined and separated from the catch basin. A separation prevention rib(102) is extended from the connecting pipe and has hanging sill(102a) on the end part which locks on to the edge of the lower opening. |
