Problems solved by technology

When the sound-absorbing panel and the supporting rib column are connected and fixed, due to the size difference between the sound-absorbing panel and the supporting rib column and the arc surface structure, the single size of the fixing part often cannot meet the installation needs.

Embodiment Construction

[0020] The present invention is further described below in conjunction with specific embodiment, and specific embodiment is the further description of the principle of the present invention, does not limit the present invention in any way, and the identical or similar technology of the present invention all does not exceed the scope of protection of the present invention.

[0021] In conjunction with the accompanying drawings.

[0022] As shown in the figure, the sound barrier of the present invention arranges multiple sets of units continuously along both sides of the railway or road, and each set of sound barrier units includes support rib columns 2 fixed on the foundation ground and multiple sets of rib columns installed and fixed between adjacent support rib columns. Sound-absorbing panels 1 arranged parallel to each other:

[0023] The sound-receiving surface of the sound-absorbing panel 1 is composed of a plurality of equally spaced concave-convex arc-shaped structures o...

Abstract

The invention discloses an acoustic board installing structure. The sound-facing surface of each acoustic board consists of a plurality of concave-convex arc-shaped structures or concave-convex trapezoidal structures which are transversely arranged at equal intervals, and two sides of the sound-facing surface of each acoustic board are fixed to supporting rib columns through expansion screws boltsby two installing blocks; each installing block is an eccentric block of a cylinder structure; an eccentric hole of a through hole structure is formed in the circle center side of the cylinder; the two installing blocks at the same side are tightly matched with and fixed to the rib columns through arc-shaped or trapezoidal vertically symmetrical inclined planes of the acoustic board; and each installing block is of a cylinder structure made of elastic materials. According to the acoustic board installing structure, the eccentric blocks made of the elastic materials are used for fixing the acoustic boards with symmetrical slope structures; the back side bonding mode is assisted; the acoustic boards can be stably and firmly fixed to the supporting rib columns; and due to the characteristicsof the eccentric blocks, the acoustic boards can be balanced and stable, so that a sound barrier can realize good self-adaptive stability in a complicated environment.

Description

technical field [0001] The invention belongs to the technical field of installation engineering component design, and relates to an installation structure for fixing a sound-absorbing panel of a sound barrier. Background technique [0002] In the construction of high-speed railways or highways, it is often necessary to set up sound barriers. The sound barriers are composed of supporting rib columns fixed on the foundation along the railway or highway and sound-absorbing panels fixed by the supporting rib columns. [0003] Sound-absorbing panels are usually made of sound-absorbing materials. In order to increase the sound-absorbing function, the sound-receiving surface usually adopts a wave-shaped multi-arc structure. When the sound-absorbing panel and the supporting rib column are connected and fixed, due to the size difference between the sound-absorbing panel and the supporting rib column and the arc surface structure, the single size of the fixing part often cannot better...
