A soundproofing barrier structure for road works

Abstract

This utility model discloses a road construction noise barrier structure, including an outer frame and an inner soundproof glass panel. In use, noise is primarily isolated through the soundproof glass panel. The outer frame has symmetrical mounting slots on both sides, and a protective component is installed inside each slot. This protective component includes: a protective element placed inside the mounting slot, with a portion protruding outside the slot; and a connector positioned between the protective element and the mounting slot, used to install the protective element and the mounting slot, and for subsequent separation as needed. An mounting plate is also installed at the bottom of the outer frame, symmetrically distributed on the front and rear surfaces. In actual installation of the noise barrier, given the numerous problems associated with current planar connection methods, such as improper installation leading to poor sound insulation, and excessively close installation distances generating significant clamping force and affecting normal installation, the present invention addresses these issues.

Description

Technical Field

[0001] This utility model belongs to the field of sound barrier technology, specifically relating to a road construction sound barrier structure. Background Technology

[0002] Noise barriers for road construction, also known as sound barriers or sound walls, are mainly installed on both sides of the road or in the central median strip to block, reflect and absorb traffic noise, thereby reducing the impact of noise on surrounding residents, schools, hospitals and other sensitive areas.

[0003] In the actual installation process of sound barriers, the commonly used sound barrier structures present some installation challenges. Specifically, each pair of sound barrier structures is connected using a planar connection method. This connection method requires high precision during installation. If the installation is not done properly, such as the connection between the two sound barriers not being tight enough or gaps existing, it can easily lead to poor sound insulation performance. Since the primary function of a sound barrier is to block the transmission of sound, the existence of gaps undoubtedly provides a channel for sound to penetrate. In addition, if the distance between the two sound barriers is too close during installation, it will create a large clamping force, which will not only increase the difficulty of installation but may also damage the sound barriers themselves, thus affecting their normal use and sound insulation effect. Utility Model Content

[0004] The purpose of this utility model is to provide a road construction noise barrier structure to solve the problems mentioned in the background art, such as poor sound insulation effect due to improper installation and interference with normal installation due to installation being too close.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road construction noise barrier structure, comprising an outer frame, with a soundproof glass panel installed inside, which mainly isolates noise during use; symmetrical mounting grooves are provided on both sides of the outer frame, and a protective component is provided inside the mounting groove, the protective component comprising: a protective member, placed inside the mounting groove, with a portion of the protective member protruding outside the mounting groove; a connecting member, disposed between the protective member and the mounting groove, which connects the protective member to the mounting groove and allows for subsequent separation as needed; a mounting plate is also installed at the bottom of the outer frame, symmetrically distributed on the front and rear surfaces of the outer frame, which is fixed to external objects during installation by bolts or other connecting members penetrating the mounting plate.

[0006] Preferably, the protective component is an adhesive strip located in the middle of the side of the outer frame. The thickness of the adhesive strip is greater than the thickness of the mounting groove. The adhesive strip flexibly connects two adjacent outer frames, achieving both sealing and allowing for slight thermal expansion and contraction. However, it also requires the two outer frames to be pressed tightly together for installation, which is a cumbersome operation. The width of the adhesive strip is less than or equal to the inner width of the mounting groove.

[0007] Preferably, the connector includes a metal plate bonded to the rear surface of the adhesive strip and a magnetic sheet installed on the inner wall of the mounting groove. The magnetic sheet is magnetically connected to the metal plate, thereby enabling quick assembly and disassembly of the adhesive strip. At the same time, due to its simple overall structure, it is also convenient to process and manufacture, and has low cost.

[0008] Preferably, the inner wall of the mounting groove has multiple through holes, the magnetic sheet is placed inside the through holes, and the two are fixed together by adhesive. The adhesive strength between the magnetic sheet and the through hole is greater than the magnetic attraction between the metal plate and the magnetic sheet, so as to avoid the phenomenon that the magnetic sheet is separated from the through hole by the adhesive strip when the adhesive strip is separated.

[0009] Preferably, the mounting plate is L-shaped and has a horizontal part and a vertical part. A through hole is provided in the vertical part of the mounting plate, and a disc spring is provided directly below the horizontal part of the mounting plate. After the bolt passes through the through hole in the vertical part of the mounting plate, the horizontal part of the mounting plate will compress the disc spring, causing the disc spring to rebound and lift the entire mounting plate. At this time, the mounting plate and the bolt will be slightly misaligned and tightened, thereby reducing or even avoiding lateral displacement at the connection between the bolt and the mounting plate.

[0010] Preferably, the mounting plate has an opening on the bottom surface of the horizontal portion, the top of the disc spring is placed inside the opening, and the vertical projection of the disc spring falls into the opening, thereby facilitating the installation of the disc spring.

[0011] Preferably, the top of the outer frame is tilted to one side, and the top of the adhesive strip has the same slope as the top of the outer frame, thereby facilitating the splicing between each pair of outer frames.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the actual installation of sound barriers, given the numerous problems associated with the current planar connection method, such as poor sound insulation due to improper installation and excessively close installation distances causing significant pressure and affecting normal installation, this invention adds an easily detachable adhesive strip to the side of the sound barrier. This adhesive strip has excellent sealing performance and can effectively eliminate any gaps between two sound barriers during installation, preventing sound from penetrating through the gaps and thus ensuring sound insulation quality. At the same time, due to the arrangement of the adhesive strip, it is not necessary to tightly adhere the two sound barriers during installation, and the presence of the adhesive strip will not cause excessive pressure, thus not affecting normal installation.

[0027] The bottom of the outer frame 100 is also equipped with a mounting plate 102, which is symmetrically distributed on the front and rear surfaces of the outer frame 100. During installation, the mounting plate 102 is fixedly installed with the external object by means of bolts or other connecting parts.

The thickness of the adhesive strip 200 is greater than the thickness of the mounting groove 103. The adhesive strip 200 flexibly connects every two adjacent outer frames 100, which can achieve sealing and allow for slight thermal expansion and contraction. However, it also requires the two outer frames 100 to be pressed tightly together to complete the cumbersome installation operation. The width of the adhesive strip 200 is less than or equal to the inner width of the mounting groove 103.

[0029] In this embodiment, preferably, the connector includes a metal plate 201 bonded to the rear surface of the adhesive strip 200, and a magnetic sheet 105 installed on the inner wall of the mounting groove 103. The magnetic sheet 105 is magnetically connected to the metal plate 201, thereby enabling quick assembly and disassembly of the adhesive strip 200.
