Noise reduction device for constructional engineering

The utility model relates to the technical field of noise reduction devices, in particular to a noise reduction device for constructional engineering, which comprises a plurality of acoustic board bodies, and a clamping mechanism is arranged between two sides of each two adjacent acoustic board bodies. The clamping mechanism comprises columns fixedly installed on one sides of the two different acoustic panel bodies respectively, a straight plate is horizontally connected between the outer sides of the two sleeves, the tail ends of the columns are in threaded connection with limiting plates, and the diameter of the limiting plates is larger than that of the columns. According to the connecting device, a plurality of acoustic boards can be connected with one another, the connecting stability is improved, meanwhile, the installation time is effectively shortened, meanwhile, noise can be effectively adsorbed, and noise pollution is avoided. 本实用新型涉及降噪装置技术领域，尤其是一种建筑工程用降噪装置，包括多块吸音板本体，相邻两块所述吸音板本体两侧之间均设置有卡合机构；所述卡合机构包括
