Embodiment 1

[0030] Such as figure 1 , 2 , 3 and 4, an external sound barrier includes 4 H steel columns 1 and 3 sound barrier unit panels 2 fixedly arranged at intervals along the edge of the roadbed 3, wherein the 4 H steel columns 1 are perpendicular to the roadbed 3 set, and the distance between the adjacent H steel columns is 2m, and the sound barrier unit plate 2 is 6m long and 0.5m wide. The sound barrier unit plate of the present invention is installed on the outer flange of the H steel column 1 facing away from the road, and the length direction of the sound barrier unit plate 2 is perpendicular to the H steel column 1, and spans 4 along the length direction. H steel column 1. The two sides along the length direction of the sound barrier unit plate 2 are formed with groove-and-groove structures that can be plugged into each other. The groove-and-groove structure includes a first groove formed on one side of the sound barrier unit plate and a A second rebate on one side of the f...

Embodiment 2

[0032] Figure 5 It is a top view of the second embodiment of the external-mounted sound barrier of the present invention, four square steel columns 14 and three sound barrier unit panels 2 are fixedly arranged at intervals along the edge of the roadbed, wherein the adjacent square steel columns 14 are The distance is 2m; the sound barrier unit plate is the same as that in Embodiment 1, and its length direction is perpendicular to the square steel column 14, and it spans 4 square steel columns 14 along the length direction. Drill holes at the corresponding positions on the two sides of the square steel column 14 facing the track and back to the track, and the open end of the U-bolt 13 passes through the perforation below the second groove and the two sides of the square column from the side away from the track Correspondingly drill holes, and use nuts to tighten the sound barrier unit plate 2 to fix the outer surface of the square steel column facing away from the track, and i...

Embodiment 3

[0034]Five square steel columns 14 and three sound barrier unit panels 2 are fixedly arranged at intervals along the edge of the roadbed, wherein the distance between adjacent square steel columns 14 is 2m; the length of the sound barrier unit panel 2 is 8m and the width is 0.5m, its structure is the same as that of Embodiment 1, the length direction of the sound barrier unit plate 2 is perpendicular to the square steel column 14, and spans five square steel columns 14 along the length direction. Before installing the external sound barrier, a fixed plate 15 of corresponding size is prefabricated, and drilling holes are set at corresponding positions on the fixed plate 15 . Such as Figure 6 As shown, the open end of the U-shaped bolt 13 passes through the perforation below the second groove draw-in groove from the side away from the track and passes through the borehole on the fixing plate 15 along the two sides of the square steel column, and uses nuts to tighten to make all...

Abstract

The invention discloses an externally-hung sound barrier which comprises multiple uprights and multiple sound barrier unit plates, wherein the uprights are fixedly arranged along the roadbed edge at intervals; the sound barrier unit plates are mounted on the uprights; each sound barrier unit plate is fixed on the outer side surface of the upright back to a road track through a connecting piece, and transversely crosses over more than 3 uprights along the length direction; tongue-groove structures which are spliced and fastened with each other are formed on the two sides of the sound barrier unit plate along the length direction; a closed connecting piece joint containing area is formed in the splicing area of the tongue-groove structures; and one end of the connecting piece with thread penetrates through the a through hole in the splicing area, and the other end is located in the connecting piece joint containing area so that the up-down adjacent sound barrier unit plates are spliced with each other to form a mounting plane. The externally-hung sound barrier disclosed by the invention realizes firm connection, and has high safety performance and beautiful appearance.

Description

technical field [0001] The invention relates to a device structure for environmental noise control, in particular to an external sound barrier used in high-speed railway construction. Background technique [0002] Noise pollution control is actually to control the pollution that has already been formed. With the rapid development of highways, railways, and urban rail transit, sound barriers occupy an important position in traffic noise control technology, and are currently recognized as one of the most effective means of controlling traffic noise at home and abroad. [0003] Chinese patent document CN201738253U discloses an integral sound barrier, in which the left and right ends of the sound-absorbing and insulating unit are fastened in the channel steel column, and the sound-absorbing and insulating components in the upper and lower positions are connected by "U"-shaped channel steel, in which " The back plate connecting plate and the panel connecting plate are respective...
