Section bar combined type high-strength metal sound barrier
The invention provides a sound barrier unit which comprises a profile outer frame unit and an acoustic structure unit, the acoustic structure unit is fixed on the profile outer frame unit, the profile outer frame unit comprises an upper profile, a lower profile and at least two frame profiles, and the upper profile, the lower profile and the frame profiles are combined to form the profile outer frame unit; the acoustic structure unit comprises a sound insulation structure unit and a sound absorption structure unit, the sound insulation structure unit faces the noise reduction direction, and the sound absorption structure unit faces the noise source direction; the sound insulation structure unit and the sound absorption structure unit are respectively fixed by an upper section bar, a lower section bar and at least two frame section bars; the invention further provides a section bar combined type high-strength metal sound barrier which comprises a sound barrier unit group formed by a group of sound barrier units which are spliced up and down, steel stand columns are arranged on the left side and the right side of the sound barrier unit group, and a top cover plate is arranged at the top of the sound barrier unit group. According to the sound barrier in a profile combination form, the mechanical strength of a traditional sound barrier can be further improved, the structural stability is improved, and the use safety is improved.
本发明提供一种声屏障单元，包括型材外框单元和声学结构单元，声学结构单元固定于型材外框单元上，型材外框单元包括上部型材、下部型材和至少两个边框型材，组合成型材外框单元；声学结构单元包括隔声结构单元和吸声结构单元，隔声结构单元朝向降噪方向，吸声结构单元朝向噪声源方向；隔声结构单元和吸声结构单元分别由上部型材、下部型材和至少两个边框型材固定；还提供一种型材组合式高强金属声屏障，包括由一组上下拼接的声屏障单元构成的声屏障单元组，声屏障单元组的左右两侧设置有钢立柱，声屏障单元组的顶部设置有顶部盖板。本发明使用型材组合形式的声屏障可以进一步提高传统声屏障的力学强度，增加了结构的稳定性，提高使用的安全性。
