Sandwich concrete wall body applied to energy consumption and sound insulation of elevator room and elevator room

Abstract

The utility model relates to the technical field of elevator room sound insulation, and provides a sandwich concrete wall body applied to energy consumption and sound insulation of an elevator room and the elevator room, the sandwich concrete wall body comprises a middle sound insulation and noise reduction layer and two concrete structure layers arranged on the two sides of the middle sound insulation and noise reduction layer, and the concrete structure layers and the middle sound insulation and noise reduction layer are tightly attached to form a whole. Tie bars are arranged in the concrete structure layers, the thickness of the two concrete structure layers is equal, and the thickness of the concrete structure layers is larger than that of the middle sound insulation and noise reduction layer. By the adoption of the sandwich wall structure, construction is easy and convenient, the middle sound insulation and noise reduction layer can effectively absorb and block noise generated by elevator running, the concrete structure layers on the two sides further enhance the sound insulation effect of the wall, noise blocking is greatly improved, meanwhile, appropriate energy dissipation rigidity can be formed between main body structures, and the noise reduction effect is greatly improved. The earthquake action is effectively consumed under the earthquake action, and the sandwich concrete partition wall is easy to replace and repair when being damaged due to energy consumption.
