The present invention relates to a prefabricated horse stable. The prefabricated horse stable in accordance with the present invention comprises: quadrangular prefabricated panels, wherein two vertical frames having insertion holes in each upper end and lower end are formed in both horizontal edges； a first fixing device having a fixing plate and two fixing projections protruding from the fixing plate at regular intervals； a first connecting device having first attaching plates attached to one side of the prefabricated panels, first extension plates bent in the horizontal direction from the end of the first attaching plates and extended, and connection pins vertically protruding from the center of the first extension plates； and a second connecting device having second attaching plates attached to the other side of the prefabricated panels, second extension plates bent in the horizontal direction from the end of the second attaching plates and extended, and connection holes formed in the center of the second extension plates. Therefore, two prefabricated panels are fabricated by inserting the fixing projections in the adjacent insertion holes using the first fixing device in the case of horizontally fabricating two prefabricated panels, whereas in the case of vertically fabricating two prefabricated panels, the first connecting device is mounted in the lateral join of one prefabricated panel and the second connecting device is mounted in the lateral join of the other prefabricated panel to allow the connection pins to be inserted in the first connection holes so as to fabricate the panels.본 발명은 조립식 마방에 관한 것으로, 본 발명에 따른 조립식 마방은, 상단 및 하단에 각각 삽입홀이 각각 형성된 2개의 수직프레임이 수평방향 양 가장자리에 형성된 사각형상의 조립식 패널들과； 고정판과 상기 고정판에 일정간격으로 돌출된 두 개의 고정돌기들을 가지는 제1고정구와； 상기 조립식 패널들의 일측면에 부착되기 위한 제1부착판과, 상기 제1부착판의 단부에서 수평방향으로 절곡되어 연장되는 제1연장판과, 상기 제1연장판의 중심부위에서 수직방향으로 돌출되는 연결핀을 구비하는 제1연결구와； 상기 조립식 패널들의 타측면에 부착되기 위한 제2부착판과, 상기 제2부착판의 단부에서 수평방향으로 절곡되어 연장되는 제2연장판과, 상기 제2연장판의 중심부위에 형성되는 연결홀을 구비하는 제2연결
