Description

Technical Field

[0001] The utility model relates to a noise protection device, in particular to a transparent sound barrier. Background Art

[0002] A sound insulation wall, also known as a sound barrier, refers to a facility inserted between a sound source and a receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located. It is mainly used for sound insulation and noise reduction of roads, highways, elevated composite roads and other noise sources. Sound barriers are divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation, and the latter is a more effective sound insulation method. Highways and expressways are the places where various types of sound barriers are used the most.

[0003] Sound barriers can generally be divided into vertical sound barriers and fully enclosed sound barriers according to their structural forms. A vertical sound barrier generally includes steel profiles and a sound barrier panel arranged between adjacent steel profiles. The sound barrier panel can be divided into a metal panel and a non-metal panel, and the non-metal panel is further divided into a transparent panel and a cement-based panel. Existing transparent panels generally use glass or acrylic panels as sound insulation boards. Acrylic panels are widely used due to their light weight, impact resistance, and high permeability. However, when subjected to a large impact, the acrylic panel will still break. To prevent the fragments of the acrylic panel from scattering on the ground and causing secondary injuries, the usual method is to add horizontal ribs inside the acrylic panel. According to the provisions of the GB / T29641 standard, during the impact resistance test of the reinforced acrylic panel, the acrylic panel is fixed in the left, right, and lower directions. After impact, the acrylic panel breaks from the middle, and the crack runs through the entire acrylic panel from left to right, dividing the acrylic panel into upper and lower parts. The lower part is fixed in the left, right, and lower directions, and the upper part is only fixed in the left and right directions and is extremely easy to fall off. The fallen upper part is used as falling fragments, which has a risk of injuring people. Therefore, avoiding the upper part of the broken acrylic panel from falling off becomes a technical problem to be solved. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a transparent sound barrier.

[0005] The technical solution adopted by the utility model to solve the above technical problem is as follows:

[0006] A transparent sound barrier includes several columns arranged at intervals and a transparent unit panel arranged between the columns. The transparent unit panel includes an acrylic panel and an aluminum profile covering the edge of the acrylic panel. The acrylic panel is provided with a horizontal reinforcing rib, and the acrylic panel is also provided with a vertical reinforcing rib.

[0007] Preferably, the vertical reinforcing ribs intersect with the horizontal reinforcing ribs, and the vertical reinforcing ribs are arranged in parallel between them.

[0008] Preferably, the vertical reinforcing ribs are perpendicular to the horizontal reinforcing ribs.

[0009] Preferably, the vertical reinforcing ribs are arranged at the left and right ends of the acrylic plate.

[0010] Preferably, a total of 4 to 16 vertical reinforcing ribs are provided, and the vertical reinforcing ribs are arranged parallel to each other.

[0011] Preferably, both ends of the horizontal reinforcing rib extend out of the end of the acrylic plate and are fixed on the aluminum profile.

[0012] Preferably, the aluminum profile is provided with an opening, and after the end of the horizontal reinforcing rib passes through the opening, it is fixed to the column.

[0013] Preferably, the vertical reinforcing rib can be selected from steel wire ropes, steel wires or rubber strips.

[0014] Preferably, several protrusions are provided on the vertical reinforcing rib.

[0015] The beneficial effects of the present invention are as follows: The transparent sound barrier provided by the present invention is provided with vertical reinforcing ribs on the basis of setting horizontal reinforcing ribs in the existing acrylic plate. When the transparent sound barrier is impacted, due to the strengthening connection of the horizontal and vertical reinforcing ribs, the broken acrylic sheets are simultaneously pulled by the horizontal and vertical reinforcing ribs and will not fall onto the road surface to cause secondary injuries to pedestrians. Compared with the acrylic plate with only horizontal reinforcing ribs, its connection strengthening force is stronger, and it can prevent the broken acrylic sheets from detaching in two directions. Moreover, the vertical reinforcing ribs are only arranged at both ends of the acrylic plate, and when in use, the vertical reinforcing ribs are covered by the aluminum profiles at the edges, which does not affect the aesthetic effect and has a very broad application prospect.

[0020] The following further details the embodiments of the present invention with reference to the accompanying drawings.

[0021] As Figure 1 、 2, as shown in FIGS. 3, the present utility model provides a transparent sound barrier, which includes several columns 1 arranged at intervals and a transparent unit board arranged between the above-mentioned columns 1. The distance between the columns 1 is generally selected to be 1-4 m. In actual cases, it is usually selected to be about 2 m. The transparent unit board includes an acrylic board 2 and an aluminum profile 3 wrapped around the edge of the acrylic board 2. In this embodiment, the acrylic board 2 is quadrilateral, specifically rectangular or square. The aluminum profile 3 is wrapped around the edge of the acrylic board 2. Transverse reinforcing ribs 4 are arranged in the acrylic board. To further prevent the fragments from scattering after the acrylic board is impacted, vertical reinforcing ribs 5 are also arranged in the acrylic board, ensuring that the acrylic fragments are connected together in both the horizontal and vertical directions. Specifically, the vertical reinforcing ribs 5 intersect or are perpendicular to the transverse reinforcing ribs 4, and the vertical reinforcing ribs 5 are arranged parallel or approximately parallel to each other. In this embodiment, the vertical reinforcing ribs 5 are arranged at both ends of the acrylic board 2. When in the installed state, the vertical reinforcing ribs 5 are blocked by the outer aluminum profile 3 or the edges of the columns 1, avoiding visual unsightliness. The vertical reinforcing ribs 5 can be set to 4-16 according to actual needs, and they are evenly distributed at both ends of the acrylic board. If the appearance effect is not considered, the vertical reinforcing ribs 5 can also be evenly arranged on the acrylic board 2, which can better play the role of pulling the fragments to prevent them from scattering. The vertical reinforcing ribs can be selected as steel wires, steel cables or rubber strips. To increase the connection strength and prevent breakage due to collision, steel wires or steel cables can be selected as the reinforcing ribs.

[0022] As Figure 4 shown, to strengthen the connection strength between the vertical reinforcing ribs 5 and the acrylic board 2, several protrusions 51 can be arranged on the vertical reinforcing ribs 5. The protrusions can prevent small acrylic fragments from detaching from the vertical reinforcing ribs. The protrusions can be selected as circular, square, cylindrical, etc. according to actual situations. The protrusions can be prepared by knotting, welding or additionally sleeving protrusion components, etc.

[0023] To further prevent the acrylic board from falling onto the road surface, both ends of the transverse reinforcing ribs 4 respectively extend out of the ends of the acrylic board and are fixed on the aluminum profile. Specifically, openings are arranged on the aluminum profile. After the ends of the transverse reinforcing ribs 4 pass through the openings, they are fixed to the columns.

[0024] The above-described embodiments are only one of the more preferred specific embodiments of the present utility model. The usual changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included in the protection scope of the present utility model.
