Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, and in particular to an FRP sound barrier. Background Technology

[0002] FRP (fiberglass reinforced plastic) sound barriers are high-efficiency sound barriers made of glass fiber or other fiber materials combined with a polymer matrix. FRP materials have good sound absorption and sound insulation properties, which can effectively reduce the noise level of passing through and provide a quiet space for the surrounding environment.

[0003] The existing announcement number is CN222160987U, entitled "A Modular Sound Barrier," which includes several columns arranged in sequence and sound barrier unit panels inserted between adjacent columns. Each column includes a base plate and two parallel wing plates fixed to the base plate. The left and right side plates have a mating convex-concave structure, as do the upper and lower side plates. Adjacent sound barrier unit panels, including those adjacent vertically and horizontally, are joined using a convex-concave structure. Therefore, the web of the traditional H-beam can be omitted, and only steel sections with two wing plates are used for fixing. This avoids the need for the width of the sound barrier unit panel to match the distance between adjacent steel sections in traditional H-beam structures; excessive width or insufficient width will lead to construction inconvenience and reduced efficiency. The sound barrier unit panel has a relatively large dimensional flexibility within a certain range, improving production and installation efficiency.

[0004] However, the aforementioned modular sound barrier itself does not have an assembly structure. It requires the pre-installation of H-shaped steel structures at the installation points for later installation of the sound barrier. This assembly method is inconvenient to install. The assembly of multiple sound barriers does not have a pre-anchored structure. During installation, it relies entirely on the limiting support of the H-shaped steel structure, which reduces the limiting performance of the assembly of multiple sound barriers and is not conducive to improving the assembly stability of the sound barrier. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes an FRP sound barrier.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an FRP sound barrier, including a support member, an FRP sound barrier and a support rod. The support member includes a support base, which is horizontally fixed at the installation point. Multiple FRP sound barriers are vertically assembled above the support base. Multiple assembly grooves are horizontally opened on the top surface of the FRP sound barrier, and multiple assembly blocks are horizontally opened on the bottom surface of the FRP sound barrier. Multiple assembly blocks at the vertically adjacent ends of the multiple FRP sound barriers are inserted into the multiple assembly grooves. A side protrusion is vertically fixed on the rear side of one vertical end face of the FRP sound barrier, and a side groove is vertically fixed on the front side of the other vertical end face of the FRP sound barrier. The side protrusion and side groove on the adjacent side end faces of the FRP sound barrier are assembled. A through hole is vertically opened through the upper and lower end faces of the FRP sound barrier, and a support rod is vertically slidably inserted into the through hole.

[0007] As a preferred embodiment, the top surface of the support has multiple horizontal and vertical connecting grooves, which are inserted into multiple assembly blocks on the bottom surface of the FRP sound barrier.

[0008] As a preferred embodiment, multiple connecting rods are fixed horizontally and vertically on the top surface of the support, and the top surfaces of the multiple connecting rods are vertically provided with threaded grooves.

[0009] As a preferred option, multiple anchor rods are vertically fixed on the bottom surface of the support, and multiple ground nails are vertically installed through the rear end surface of the support.

[0010] As a preferred embodiment, a sealing groove is provided on the top surface of the FRP sound barrier, and a sealing frame is horizontally fixed on the bottom surface of the FRP sound barrier, with the sealing frames of multiple adjacent FRP sound barriers inserted into the sealing groove.

[0011] As a preferred option, sound-absorbing cotton is embedded and fixed on one vertical end face of the FRP sound barrier.

[0012] As a preferred embodiment, the upper end face of the support rod is provided with a threaded groove, and the lower end face of the support rod is vertically fixed with a stud. The studs at adjacent ends of multiple support rods are threadedly assembled with the threaded groove, and the studs at the bottom of multiple support rods are threadedly assembled with the threaded groove on the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When multiple FRP sound barriers made of FRP material are stacked vertically at the installation point, the supports on the support members are pre-fixed at the installation point, and then the FRP sound barriers are vertically assembled on the supports. When multiple FRP sound barriers are vertically assembled and connected, multiple assembly blocks at the upper and lower ends of the multiple FRP sound barriers are inserted one by one into multiple assembly grooves to pre-anchor and limit the adjacent FRP sound barriers, ensuring the alignment stability of the adjacent FRP sound barriers. At the same time, when adjacent FRP sound barriers are laterally assembled, the side protrusions and side grooves on the adjacent side end faces of the FRP sound barriers are assembled, and the lateral pre-anchor and limit assembly of the FRP sound barriers ensures the pre-anchor and limit stability of the FRP sound barrier assembly.

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

When multiple FRP sound barriers 2 are vertically assembled and connected, multiple assembly blocks 22 at the upper and lower ends of multiple FRP sound barriers 2 are inserted one by one into multiple assembly grooves 21 to pre-anchor and limit the adjacent FRP sound barriers 2, ensuring the alignment stability of the adjacent FRP sound barriers 2. At the same time, when adjacent FRP sound barriers 2 are laterally assembled, the side protrusions 23 and side grooves 24 on the adjacent side end faces of the FRP sound barriers 2 are assembled, and the lateral pre-anchoring and limiting assembly of the FRP sound barriers 2 ensures the pre-anchoring and limiting stability of the FRP sound barrier 2 assembly.

[0027] In one embodiment, such as Figure 2 and 3 As shown, multiple connecting grooves 12 are horizontally and vertically formed on the top surface of the support 11, and these grooves 12 are inserted into multiple assembly blocks 22 on the bottom surface of the FRP sound barrier 2.
