The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
A kind of closed sound barrier comprises a plurality of " door " Zee bar steel Z structure stand; The adjacent successively arrangement of described support, and each plane, support place does not overlap; Beam 2 on post 1 constitutes described support by two posts 1 and crossbearer, and the material of post 1 and beam 2 all is a channel-section steel;
Also comprise acoustical board 3 and sound barrier 7, acoustical board 3 and sound barrier 7 are connected in respectively in the channel-section steel notch of adjacent two stands;
