Description

Technical Field

[0001] This utility model relates to the field of sound barriers, and in particular to a non-detachable insert-type sound barrier unit panel. Background Technology

[0002] Existing plug-in type sound barriers are installed by inserting the barrier unit panels between two H-shaped columns. While this method relies on the flanges for restraint in the vertical direction, it allows for significant displacement along the flange direction. As a crucial component of the sound barrier, the existing sound barrier unit panels lack positioning and restraint measures along the installation track during installation. This easily leads to misalignment of the unit panels after installation, resulting in large gaps at one end. During track operation, the sound barrier unit panels are subjected to wind pressure vibrations from trains, causing them to shift to one end. In this case, the unit panels can slide between the two H-shaped columns. If the unit panel gets too close to one end, the other end may detach from the H-shaped column's restraint, causing it to fall off and seriously affecting traffic safety. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a sound barrier unit panel with good sound insulation effect, convenient installation, and positioning and limiting functions to prevent falling off.

[0004] The present invention provides a non-fall-off insert-type sound barrier unit panel, the technical solution of which is as follows:

[0005] A type of anti-fall-off insert-type sound barrier unit panel is disclosed. The upper surface of the sound barrier unit panel has a protrusion, and the lower surface has a recess that matches the shape of the protrusion. Multiple sound barrier unit panels are inserted into H-shaped steel columns to form a sound barrier. The protrusion and recess of the sound barrier unit panel are interlocked, making the sound barrier unit panel stable and improving the sound insulation effect. The H-shaped steel columns are fixed to the ground by a base plate. Limiting devices are symmetrically arranged on both sides of the back of the sound barrier unit panel. The limiting devices cooperate with the flanges of the two H-shaped steel columns to prevent the sound barrier unit panels from sliding and falling off.

[0006] Furthermore, the limiting device is an angled steel section, which is fixed to the sound barrier unit plate by welding or bolts.

[0007] Furthermore, bolt holes are provided on the base plate of the H-shaped steel column, which is fixed to the ground by bolts.

[0008] Furthermore, the H-shaped steel columns are welded and fixed to the base plate.

[0009] The implementation of this utility model has the following technical effects:

[0010] This invention reliably fixes two limiting devices on the back of the sound barrier unit panel, providing positioning and limiting functions. This prevents the unit panel from shifting towards one H-shaped column due to vibration, resulting in a large gap at the other end. In extreme cases, the unit panel could detach from the column, posing a safety hazard. The limiting devices ensure the unit panel is installed in the center, preventing the entire unit panel from detaching due to one end falling off first. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the embodiments and accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention and do not constitute any limitation thereof.

[0017] See Figures 1 to 4As shown in this embodiment, a non-falling insert-type sound barrier unit panel is provided. The upper surface of the sound barrier unit panel 1 is provided with a protrusion 10, and the lower surface is provided with a recess 11 that matches the shape of the protrusion 10. Multiple sound barrier unit panels 1 are inserted into H-shaped steel columns 2 to form a sound barrier. The protrusion 10 and the recess 11 of the sound barrier unit panel 1 are interlocked, making the sound barrier unit panel 1 stable and providing better sound insulation. The H-shaped steel columns 2 are fixed to the ground by a base plate 21. Limiting devices 12 are symmetrically provided on both sides of the back of the sound barrier unit panel 1. The limiting devices 12 cooperate with the flanges 20 of the two H-shaped steel columns to prevent the sound barrier unit panel 1 from sliding and falling off. Further, the limiting device 12 is an angled steel, which is fixed to the sound barrier unit panel 1 by welding or bolts. The distance between the two angled steel pieces is slightly smaller than the closest distance between the flanges 20 of the two H-shaped steel columns, ensuring convenient installation while also providing a limiting function. The base plate 21 of the H-shaped steel column 2 is provided with bolt holes for fixing to the ground with bolts, facilitating installation. The H-shaped steel column 2 is welded to the base plate 21. This invention reliably fixes two limiting devices 12 on the back of the sound barrier unit panel 1, providing positioning and limiting functions. This prevents the unit panel from shifting towards one end of the H-shaped column due to vibration, resulting in a large gap at the other end. In extreme cases, the unit panel may detach from the column, posing a safety hazard. The limiting devices ensure the unit panel is centered during installation, preventing the entire unit panel from detaching due to one end falling off first.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
