Abstract

This invention relates to an axial load-supporting soundproofing wall. In particular, joint caps are provided at the upper and lower portions of the vertical support bars of the unit soundproofing panel section, so that the load of each unit soundproofing panel section is not transmitted to the lower part through the soundproofing plate of the unit soundproofing panel section, but rather to the lower part. This relates to a soundproofing wall supporting axial load that is transmitted to the lower part through the vertical support bar of the unit soundproofing panel part, thereby preventing deformation of the soundproofing panel.

Description

Support soundproof wall {SOUNDPROOF WALL FOR SHAFT LOAD}

This invention relates to an axial load-supported soundproofing wall, wherein joint caps are provided at the upper and lower parts of the vertical support bars of the unit soundproofing panel section, which is formed by a soundproofing plate inside a square soundproofing plate frame, so that the load of each unit soundproofing panel section passes through the soundproofing plate. It relates to a soundproofing wall supporting axial load, which is not transmitted to the lower part, but is transmitted to the lower part through the vertical support bar of the soundproofing panel frame of the unit soundproofing panel unit, thereby completely preventing deformation of the soundproofing panel.

As the road network continues to expand in line with the recent increase in vehicles, areas affected by road traffic noise are appearing not only in downtown areas but also in local cities. To solve this problem, soundproof walls are being installed on both sides or one side of the road.

A soundproof wall refers to a wall installed on both sides or one side of a road to reduce or block road traffic noise, and is the most commonly applied method among road traffic noise reduction measures.

Currently, the most commonly applied soundproofing wall soundproofing panel among road traffic noise reduction measures in Korea is a transparent soundproofing panel made of tempered laminated glass, PC plastic, or acrylic (PMMA), which is fixed to the soundproofing panel frame of the unit soundproofing panel section. Among them, tempered laminated glass is increasingly being used as a material for reflective transparent soundproofing plates. The tempered laminated glass is strong against external shocks, does not generate fragments when broken due to the film adhered to the surface, and also facilitates visibility. It also has the advantage of being beautiful.

The axial load-bearing soundproof wall generally consists of three parts: a foundation, a support, and a unit soundproofing panel. First, a foundation is installed on the ground, and a support such as H-beam is installed on the foundation, and the unit soundproofing panel is fixed to the support. It is constructed in a manner that is fixed to the back. The unit soundproofing panel unit is provided with a soundproofing plate such as reinforced laminated glass inside a square soundproofing plate frame.

As a conventional technology for such soundproofing walls, a maintenance type soundproofing panel and soundproofing support 40 that facilitate partial replacement of damaged transparent panels and frames in Publication Patent Publication No. 10-2022-0014660 (2022.02.07) were proposed, and the proposed The technology improves assembly by consisting of a horizontal frame provided on the front and back of the soundproofing panel assembled between H-shaped columns, a vertical frame that secures the horizontal frame to the H-shaped column, and stud bolts that secure the vertical frame to both sides of the H-shaped column. Although the construction of the soundproof wall was carried out efficiently and only the damaged parts of the soundproofing panel could be replaced, there was a problem that replacement was cumbersome and workability was lowered as the process of loosening and tightening multiple stud bolts was required.

In addition, in the case of a multi-layered soundproofing board as the lower part of the soundproofing board is inserted into the horizontal frame and assembled, the weight of the soundproofing board positioned at the top is repeatedly transferred to the lower part through the horizontal frame, thereby increasing the weight on the soundproofing board positioned at the bottom. There was a problem that the sound insulation panel was easily deformed and damaged due to concentration.

In this way, the sound insulation plate 20 is replaced by separating the sound insulation plate fixing part 30 from the vertical support bar 120 through the same process and then attaching it again. At this time, the sound insulation plate fixing bar 30 is coupled to the horizontal support bar 110 located at the top of the sound insulation plate frame 10 and then to the vertical support bar 120, and then to another horizontal support located below. By being coupled to the bar 110, it is possible to prevent interference from occurring.

Figure 10 is a perspective view showing another embodiment of the axial load-bearing soundproof wall according to this invention.

In this invention, the gap between the other horizontal support bars 110 stacked on top of the horizontal support bar 110 is prevented from being exposed while improving the aesthetics, and the shape is a hollow half-moon shape on the front. However, in addition to this form, as shown in FIG. 10, the front diffraction member 720 is provided at the front end of the front locking piece 510. By providing a front diffraction member 720' having a shape, it is possible to prevent noise generated from the lower part from diffracting and spreading to the upper part while improving the aesthetics.
