Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 9, sound barrier of the invention, including prefabricated just frame and zigzag sound insulationg board, on sound insulationg board
It is provided with sound-absorbing material；Prefabricated just frame is the internal fold-line-shaped structure for being filled with sound-absorbing material, and fold-line-shaped structure includes level
Section and tilting section, horizontal segment are installed in supporting beam and are connected by connector with track girder, tilting section relative to track girder to
Outer extension；Zigzag sound insulationg board is arranged on tilting section against in the one side of track girder.
Because straddle-type monorail is horizontal more than more than rail level in the following radiated noise of rail level, study through many experiments and repeatedly
And contrast, verification draw maximum at 1.5m below rail level, the track of monorail transit is banding pattern beam body, noise barrier structure
Connected by H-type component, effectively absorbed sound in noise source bottom, strengthen the noise reduction of sound barrier, and do not influence both sides sight
Permeability and landscape requirement, steel-frame structure be integrally located at below pilot's line of vision, do not influence to drive.
In the present embodiment, the sound barrier in Fig. 1 is connected to track girder side by H-type component.H-type component is arranged at single track
Between track girder and supporting beam, the I-shaped hollow section of the concrete track beam of monorail transit is highly 1.5m, width
0.85m, H-type component are connected by bolt with track girder.Broken line type noise barrier structure can preferably adapt to straddle-type monorail beam knot
Structure and noise behavior, broken line type sound barrier and horizontal segment angle are between 120 ° to 135 °.Perforate passes through bolt on H-type component
It is connected with track girder.The fold-line-shaped that prefabricated steel frame includes close to track girder side constructs, and passes through the sound absorption material being placed in construction
Material achievees the purpose that sqouynd absorption lowering noise.
The prefabricated general frame of broken line type is broken line type steel plate framework structure, bottom fold angle between 120 ° to 135 °,
Galvanized steel plain sheet is inlayed in frame, prevents train from making structure unstable by caused power, while increase noise reduction intensity.Steel frame
Unit specification is 500 × 490 × 40 (height × width x thickness, unit mm).Prefabricated just frame can reduce with galvanized steel plain sheet construction
The radiated noise and reflecting background produced from the traveling of hypomere train.Galvanized steel plain sheet and pre-manufactured steel frame welding, reserving gaps 1-
2mm or so.Sound insulation sqound absorption construction plate is made of zigzag sound insulationg board and triangle sound-absorbing material.Groove is done in sound insulation version side, with
Prefabricated just frame sides mouth welding.Bottom can effectively stop for sound insulationg board and reflecting background maximum noise.Sound insulationg board is plating
Zinc steel plate, sound insulationg board are reflecting background face, and sound-absorbing material is absorption of noise face.As shown in figure 8, sound insulationg board indention, sound insulation
The long side thickness of Slab element is 8cm, and the cross section of sound-absorbing material is right angled triangle, and top width 2-3cm, is highly 3cm.
The above is only the preferred embodiment of the present invention, it should be pointed out that：For those skilled in the art, exist
Without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should be regarded as this hair
Bright protection domain.
