Noise-reduction energy-saving type deformation joint structure and building

The utility model provides a noise-reducing energy-saving type deformation joint structure and a building, and the scheme is as follows: aiming at deformation joints of a building roof, an inner wall and an outer wall, a lost type deformation joint structure which is not directly communicated inside and outside is adopted, so that the performances of sound insulation, sound absorption, noise reduction, heat insulation, water resistance and the like at the deformation joints can be effectively ensured for a long time. 本实用新型提供了一种降噪节能型变形缝结构及建筑，所述方案针对建筑屋面和内外墙变形缝处，采用"迷路式"的内外不直通的变形缝结构，能够长久有效地保证变形缝处隔声、吸声降噪、隔热保温以及防水等性能。
