Abstract
The invention relates to a non-heat-bridge horizontal splicing seam for prefabricated sandwiched thermal insulation outer walls and construction steps of the non-heat-bridge horizontal splicing seam. The non-heat-bridge horizontal splicing seam comprises the prefabricated sandwiched thermal insulation outer walls. A splicing position of every two prefabricated sandwiched thermal insulation outer walls is filled with filler. The filler is polyurethane thermal insulation boards or a grouting material. A gap between every two prefabricated sandwiched thermal insulation outer walls is firstly compacted and sealed through the corresponding polyurethane thermal insulation board and then filled with the grouting material or a bed mortar material to be sealed, and the horizontal splicing seam can have both the thermal insulation performance and the waterproof performance. The filler of the horizontal splicing seam for the prefabricated sandwiched thermal insulation outer walls is partially changed into the polyurethane thermal insulation boards integrating thermal insulation and waterproofness, and the problems about a heat bridge and waterproofness of the horizontal splicing seam for wall bodies of the prefabricated sandwiched thermal insulation outer walls are solved.
