Description

LOAD TRANSFER PREVENTION TYPE SOUNDPROOF WALLS

The present invention relates to a soundproof wall that reduces vehicle running noise, etc. generated on a road or bridge, and more particularly, to individually support the load of soundproofing plates stacked vertically between the pillars of the soundproof wall to prevent the load transfer to the lower side. It relates to a load transfer prevention type sound barrier that prevents buckling by dispersing pressure due to load, increases durability by strengthening structural strength and rigidity, and makes installation and maintenance simple and easy.

Today, soundproof walls are being installed on the edges of roads, bridges, railways, factories, etc. to block or obstruct the noise transmission path for the purpose of reducing noise.

Such soundproof walls are usually formed of a barrier-type structure in which a number of soundproof plates are vertically stacked between the pillars, in which beams having an H-shaped cross-section are continuously installed at regular intervals on the ground.

There are various types of soundproofing boards according to the characteristics, use and material of acoustic performance, and depending on the purpose of use, sound-absorbing type (considering the effect of reflected sound on the area opposite to the road where the soundproofing wall is installed), reflective (sound insulation) type, and transparent type (sunshine area) and anticipation of infringement of the right of view and anticipation of freezing).

Due to the recent trend in which the height of the soundproof wall rises to 10M or more, the soundproofing board located at the middle and lower part of the soundproofing wall exerts intensive pressure (compressive load) and external force due to the excessive load of the soundproofing board located at the top. It induces phenomena such as lateral buckling, which causes deformation and loses proof strength, flexural torsional buckling that bends in the transverse direction and buckles with torsion, and local buckling caused by local deformation.

This buckling phenomenon sharply reduces the strength and rigidity of the soundproofing plate, and when the load reaches a certain size, the bending becomes severe and eventually leads to damage.

In addition, in the case of a soundproofing board located on the lower side of the soundproofing wall, deformation and sagging of the soundproofing board such as a fullness phenomenon occurs due to load transfer of the soundproofing boards stacked on the upper side thereof. There is this.

In order to solve this problem, in Patent Document 1, as shown in FIGS. 1 and 2 , a pair of H-beam steel posts 100 and a soundproof panel 300 in which a plurality are stacked between the posts 100, and the A load to prevent the load of the soundproof panel 300a located on the upper side and fixed on both sides of the support 100 so as to be located between the soundproof panels 300 from being transferred to the soundproof panel 300b located on the lower side thereof. A sound barrier composed of a transition prevention device 500 is disclosed.

However, this is a very difficult work for fixing because it is necessary to fix the load transfer prevention device 500 to the correct position according to the installation height and spacing of the soundproof panels 300 when fixing the load transfer prevention device 500 to the posts 100 , and the soundproof panel 300 . Since it is a structure that supports only both ends of the rods, there is a problem in that the middle part sags down and the deformation occurs.
