The present invention relates to a separable hypocaust slab to reduce inter-floor noise of an apartment house, comprising: a floor slab, a buffer layer installed in a bottom slab, a hot water pipe installed in the buffer layer, a mortar deposited on the buffer layer, and a hypocaust layer covering the hot water pipe. The hypocaust layer is installed to be separated into a plurality of partitioned hypocaust units having a predetermined size. A damping portion formed as an empty space or a hypocaust unit separation joint wall is provided between adjacent hypocaust units. A pipe support frame is installed between the hypocaust layer and the buffer layer, and has a same size as that of the hypocaust unit. Here, since the hypocaust unit separation joint wall installed to erect from a frame body plate of the pipe support frame is integrally formed on the edge of the frame body plate, the structure is simplified and construction easy; and even though an impulsive load is applied to the floor slab, vibration occurring in the entire hypocaust layer as in the related art is able to be prevented to reduce heavy weight impact noise, and an effect of alleviating impact of the floor slab is able to be increased. Moreover, since the pipe support frame having a fixing pin installed in a lower portion thereof and a hot water pipe fixating protrusion installed in an upper portion thereof is installed; a hot water pipe is able to easily be installed, and since the pipe support frame is simply inserted into the buffer layer by the fixating pin, a construction is facilitated. |
