An angle-adjustable support device for a floor is disclosed. The angle-adjustable support device for a floor, according to the present invention, comprises: a joist support which has a mounting part where a wooden joist is mounted and allows a height adjusting bolt to be fixed to the bottom thereof; a height adjusting part which has a height adjusting nut coupled to the height adjusting bolt and an adjusting plate for rotating the height adjusting nut in forward and reverse directions; an upper receiving member which has an upper through hole and a catching end; a lower receiving member which has a lower through hole, a receiving groove, a coupling hole, and an inclined guide part for guiding the catching end to the coupling hole; and a vibration-proof member which absorbs impact and vibration transferred from the joist support and is made of a vibration-proof material to elastically support the upper receiving member. Therefore, the present invention stably and securely supports a floor plate by forming the vibration-proof member between the upper and lower receiving members and absorbs impact and vibration transferred from the top surface of the floor plate. |
