The invention relates to the field of structural buildings, in particular to an
assembly type
green building. The
green building comprises a plurality of top plates, wherein the edges of the top plates are movably spliced, the top plates jointly form a plate shape with the two sides obliquely extending downwards, a
water storage barrel is embedded in the lower side close to the top plates, an upper corner
cutting plate and a lower corner
cutting plate are fixedly installed at an upper end opening of the
water storage barrel, the edges, close to each other, of the upper corner
cutting plate and the lower corner cutting plate jointly form an inclined channel leading into the inner side of the
water storage barrel, a plurality of anti-
evaporation pieces extend out of the lower end face of the lower corner cutting plate, a
water diversion barrel is installed on the lower end face of the top plate in an embedded mode, one end of the water guide cylinder is movably inserted into the inner side of the water storage cylinder, a plugging head is movably installed at the other end of the water guide cylinder, and a water guide rod is arranged on the inner side of the water guide cylinder. According to the
assembly type
green building, the water collecting and cooling effects can be achieved, and
noise generated when rainwater collides is reduced.
