Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, and specifically relates to an adjustable splicing and assembling structure of a vertical sound barrier. Background Art

[0002] As a key structure for road noise control, sound barriers are mainly used for sound insulation and noise reduction in bridges, highways, urban viaducts and other noise environments.

[0003] Sound barriers can generally be divided into vertical sound barriers and fully enclosed sound barriers according to their structural forms. A vertical sound barrier generally includes H-shaped steel channels and sound insulation boards arranged between adjacent H-shaped steel channels. The sound insulation boards are inserted between adjacent H-shaped steel channels. In this structure, when subjected to external forces or thermal expansion and contraction, the sound insulation boards are easily disengaged from between the H-shaped steel channels. When there are on-site installation errors, one end of the sound insulation board is also easily detached from the H-shaped steel channel or only in partial contact with the H-shaped steel channel. Once stressed, the sound insulation board is likely to become disengaged. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an adjustable splicing and assembling structure of a vertical sound barrier, which can finely adjust the relative positions between the H-shaped steel channels and the sound barrier unit boards according to the distance between adjacent H-shaped steel channels on site, and ensure that the sound barrier unit boards will not be disengaged from the H-shaped steel channels, thus ensuring the structural stability of the vertical sound barrier.

[0005] The technical solution of the utility model is as follows:

[0006] An adjustable splicing and assembling structure of a vertical sound barrier includes splicing columns and splicing strips. Splicing strips are fixedly connected to both side edges of each sound barrier unit board of the vertical sound barrier. The splicing column includes a support bottom plate and an H-shaped steel channel vertically arranged with its bottom end fixedly connected to the support bottom plate. Multiple vertically extending and parallel outer convex strips or outer strip-shaped grooves are arranged on the front and rear end faces of the splicing strip, and multiple vertically extending and parallel inner strip-shaped grooves or inner convex strips are arranged on the inner walls of the two parallel parts of the H-shaped steel channel; when splicing the vertical sound barrier, the splicing strips at the docking ends of two adjacent sound barrier unit boards respectively extend into the two U-shaped grooves of the H-shaped steel channel, and the outer convex strips on the splicing strip are embedded into the inner strip-shaped grooves of the H-shaped steel channel or the inner convex strips of the H-shaped steel channel are embedded into the outer strip-shaped grooves of the splicing strip to achieve a clamping connection.

[0007] The inner convex strips and the outer convex strips are both convex strips with a semi-circular, isosceles triangle or rectangular cross-section, and the inner strip-shaped grooves and the outer strip-shaped grooves are both strip-shaped grooves with a semi-circular, isosceles triangle or rectangular cross-section.

[0008] The spacing between multiple outward protruding strips parallel to each other on the splicing strip is exactly the same as the spacing between multiple inner strip-shaped grooves parallel to each other on the H-shaped steel channel; the spacing between multiple outward strip-shaped grooves parallel to each other on the splicing strip is exactly the same as the spacing between multiple inner protruding strips parallel to each other on the H-shaped steel channel.

[0009] The described sound barrier unit board includes a rectangular frame and a sound insulation board. A rectangular ring-shaped card slot is provided on the inner wall of the rectangular frame, and the edge of the sound insulation board is clamped in the rectangular ring-shaped card slot. Splicing strips are integrally molded on both the left and right vertical outer walls of the rectangular frame, and the width of the splicing strip is the same as the width of the outer wall of the rectangular frame.

[0010] When the described vertical sound barrier is spliced, the splicing strip completely extends into the U-shaped groove of the H-shaped steel channel or a part extends into the U-shaped groove of the H-shaped steel channel and the other part is located outside the U-shaped groove of the H-shaped steel channel.

[0011] Advantages of the present utility model:

[0012] In the present utility model, a snap connection structure composed of multiple protruding strips and multiple strip-shaped grooves is adopted between the sound barrier unit board and the splicing column, effectively avoiding the problem that the sound barrier unit board comes off the splicing column.

[0013] The present utility model can finely adjust the relative position between the H-shaped steel channel and the sound barrier unit board according to the distance between adjacent splicing columns on site, that is, the splicing strip on the sound barrier unit board can completely or partially extend into the U-shaped groove of the H-shaped steel channel. Even when there is an installation positioning error in the splicing column, a stable connection between the sound barrier unit board and the splicing column can be achieved.

[0014] The splicing strip of the present utility model and the rectangular frame of the sound barrier unit board are of an integrally molded structure, with a stable overall structure, and the sound insulation board is clamped tightly in the rectangular frame, realizing the clamping of the entire edge of the sound insulation board and avoiding damage to the sound insulation board.
