An objective of the present invention is to standardize a prefabricated flower pot capable of expressing various appearances in a bulk, so as to manufacture a large quantity of flower pots, reduce a raw material of the prefabricated flower pot, and provide expressiveness and rigidity. For the prefabricated flower pot, a support rim (100) which is integrally injection-molded with a space (S) having a narrow bottom and a wide top, is disposed on an outer circumferential surface of an upper side of a side plate (11) of a base container (10), a horizontal plate (A-2) is installed in the support rim (100) to increase the expressiveness and the rigidity, and endure external pressure. A finding ring rim (A) including a vertical plate (A-1) capable of distributing external force is inserted into a lower side of the horizontal plate (A-2). The inserted binding ring rim (A) includes a support means (150) which has a protruding or engraved support step (151) formed on a lower edge surface of the side plate (11) to be locked and fixed to the support rim (100). A locking means (200) is formed on an edge surface of the support rim (100) over the support means (150) to be maintained without separation even if shock and pressing are applied, wherein the locking means includes an insertion locking device (210) formed in an undercut type of a forcible reverse pulling type during injection molding. According to the present invention, the prefabricated flower pot is simply assembled, a mold for the prefabricated flower pot is easily and strongly manufactured, and initial manufacturing costs of the mold are reduced.본 발명은 대량으로 다양한 외관표현이 가능한 조립식 화분을 규격화하여 대량으로 생산할 수 있도록 하고, 조립식 화분 소재를 절약할 수 있도록 함을 물론 표현력과 견고성을 가지는 조립식 화분을 제공함을 그 주된 목적으로 한다.조립식 화분에서, 상기 베이스통(10)의 측판(11) 상측 외주 면으로는 아래가 좁고 위가 넓은 공간(S)을 일체로 사출성형되는 받침테(100)를 구비한 것과, 상기 받침테(100)에는 표현력과 견고성을 높일 수 있고 외부 가압에도 견딜 수 있도록 횡판(A-2)을 구비하여, 그 횡판(A-2)의 저 측으로 외부 힘을 분산시킬 수 있는 종판(A-1)이 구비된 결속링테(A)가 삽설 되도록 구비한 것과, 상기 삽설된 결속링테(A)는 받침테(100)에 걸림되
