SPLICED-TYPE ROOF HAVING WATERPROOF FUNCTION

WIPO Patent Application WO/2018/223685

A1

Disclosed is a spliced-type roof having a waterproof function. The roof comprises a plurality of top-high and bottom-low unit roof slabs spliced with each other, wherein each of the unit roof slabs comprises a roof slab body, an upper frame, a lower frame and two mutually symmetrical lateral frames; the lower frame is provided with a first transverse rain blocking sheet; the first transverse rain blocking sheet of the upper unit roof slab covers the upper frame of the lower unit roof slab; the lateral frame of the left unit roof slab is in attached connection with the lateral frame of the right unit roof slab; and a top-high and bottom-low longitudinal drainage groove is arranged below a seam in an attached connection position of two lateral frames. The characteristics thereof are that a transverse water tank is arranged below the first transverse rain blocking sheet; and an opening of the transverse water tank is located above the longitudinal drainage groove. The advantage thereof is that water infiltrating between the upper and lower unit roof slabs can be guided to flow into the longitudinal drainage groove and is drained by means of the longitudinal drainage groove, thus greatly improving the waterproof effect of same.
