Description

Technical Field

[0001] This utility model relates to the field of FRP retaining wall technology, and in particular to a lightweight and high-strength FRP retaining wall. Background Technology

[0002] In the field of civil engineering, retaining walls, as a widely used structure to prevent soil collapse and maintain soil stability, play a crucial role in various buildings, roads, bridges, and other projects. Traditional retaining walls are mostly constructed using materials such as brick, stone, concrete, or steel. Brick and stone retaining walls are typically built by laying individual bricks and stones with cement mortar. Concrete retaining walls are another common type. They are formed by pouring concrete on-site to create the wall structure. Steel retaining walls, such as sheet pile retaining walls, are also common.

[0003] Regarding the aforementioned technologies, it has been found that brick, concrete, and steel retaining walls all have significant limitations when facing certain special construction scenarios, such as narrow spaces, complex terrain, or areas with strict weight restrictions. They are difficult to flexibly splice and assemble, and cannot meet the needs of retaining walls of different sizes and shapes. Utility Model Content

[0004] This invention solves the problems in related technologies and proposes a lightweight, high-strength FRP retaining wall.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A lightweight, high-strength FRP retaining wall includes an FPR hollow web panel and connecting steel plates. The FPR hollow web panel and connecting steel plates are installed sequentially at intervals, and the FPR hollow web panel and connecting steel plates are snap-fitted and fixedly connected. The FPR hollow web panel includes an outer frame shell and reinforcing plates. The reinforcing plates are evenly installed in the outer frame shell and are integrally formed with the outer frame shell. Two sets of clamping half-covers are installed at the upper and lower ends of the outer frame shell, respectively. The clamping half-covers are clamped in the outer frame shell and connecting steel plates, and the clamping half-covers are snap-fitted and fixed to both the outer frame shell and connecting steel plates.

[0007] As a preferred embodiment, the outer frame includes bent side panels and connecting outer panels. The bent side panels are symmetrically installed on both sides of the connecting outer panels, and the bent side panels and the connecting outer panels are integrally formed.

[0008] As a preferred embodiment, the connecting steel plate includes a middle shell and an outer clamping plate, the outer clamping plate being installed on both sides of the middle shell and fixedly connected to the middle shell.

[0009] As a preferred embodiment, the clamping half cover includes a top cover plate, a first insert plate, and a second insert plate. The first insert plate and the second insert plate are both vertically installed on the lower end face of the top cover plate, and the top cover plate, the first insert plate, and the second insert plate are integrally formed.

[0010] As a preferred embodiment, a threaded half-pipe is vertically installed in the middle of the outer side surface of the first insert plate, and the threaded half-pipe is fixedly connected to the first insert plate.

[0011] As a preferred embodiment, a matching locking bolt is installed in the threaded half-pipe, and an operating rod cap is provided on the head of the locking bolt. The locking bolt and the operating rod cap are integrally formed.

[0012] As a preferred embodiment, the upper surface of the top cover plate is provided with a top groove for storing the operating rod cap.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: The lightweight, high-strength FRP retaining wall of this application organically combines FPR hollow web panels and connecting steel plates.

[0026] Reference Figure 1 , Figure 2 and Figure 3As shown, a lightweight, high-strength FRP retaining wall includes an FPR hollow web 1 and connecting steel plates 2. The FPR hollow web 1 and connecting steel plates 2 are installed sequentially at intervals, and the FPR hollow web 1 and connecting steel plates 2 are snapped together and fixedly connected. The FPR hollow web 1 includes an outer frame shell 11 and reinforcing plates 12. The reinforcing plates 12 are evenly installed in the outer frame shell 11, and the reinforcing plates 12 and the outer frame shell 11 are integrally formed. Two sets of clamping half covers 3 are installed at the upper and lower ends of the outer frame shell 11, respectively. The clamping half covers 3 are clamped in the outer frame shell 11 and the connecting steel plates 2, and the clamping half covers 3 are snapped together and fixedly connected to the outer frame shell 11 and the connecting steel plates 2. The FPR hollow web panel 1 and connecting steel plate 2 are installed and locked together at intervals. This structural design makes the overall structure of the retaining wall more stable, ensuring stable splicing and use during use. In actual use, the appropriate length can be spliced ​​according to the actual retaining dimensions. The reinforcing plate 12 in the FPR hollow web panel 1 is integrally formed with the outer frame shell 11, enhancing the structural strength of the FPR hollow web panel 1. The clamping half-cover 3 further strengthens the connection stability between the FPR hollow web panel 1 and the connecting steel plate 2. After installation, the clamping half-cover 3 can be used to shield and protect the upper and lower ends of the FPR hollow web panel 1, ensuring stable shielding use. The use of FRP material gives the retaining wall lightweight, high strength, and corrosion resistance. The FPR hollow web panel 1 uses glass fiber reinforced polymer (GFRP) composite material, which has high strength and good corrosion resistance. The outer frame shell 11 and reinforcing plate 12 are integrally formed through a molding process. The connecting steel plate 2 uses Q235 carbon structural steel, which has good strength and toughness. The middle shell 21 and the outer clamping plate 22 are fixedly connected by welding. The clamping half-cover 3 is made of the same glass fiber reinforced composite material as the FPR hollow plate 1, manufactured by injection molding to ensure its structural strength and compatibility with the FPR hollow plate 1. The locking bolts 34 are made of stainless steel, model M12, which has good corrosion resistance and strength and can meet the requirements of long-term use. The outer frame shell 11 includes bent side plates 111 and connecting outer plates 112. The bent side plates 111 are symmetrically installed on both sides of the connecting outer plates 112, and the bent side plates 111 and the connecting outer plates 112 are integrally formed. The outer frame shell 11 adopts the structure of bent side plates 111 and connecting outer plates 112 being integrally formed, which increases the structural strength and stability of the outer frame shell 11, and can better withstand external pressure. In addition, the bent side plates 111 on both sides are also easier to connect with the connecting steel plate 2, ensuring the overall flatness of the outer edge.

[0027] Reference Figure 3 As shown, the connecting steel plate 2 includes a middle shell portion 21 and an outer clamping plate 22. The outer clamping plate 22 is installed on both sides of the middle shell portion 21 and is fixedly connected to the middle shell portion 21. The fixed connection between the middle shell portion 21 and the outer clamping plate 22 of the connecting steel plate 2 improves the overall strength of the connecting steel plate 2, enabling it to better perform its function of connecting and supporting the FPR hollow web plate 1.

[0028] Reference Figure 4 and Figure 5 As shown, the clamping half-cover 3 includes a top cover plate 31, a first insert plate 32, and a second insert plate 33. Both the first insert plate 32 and the second insert plate 33 are vertically mounted on the lower end face of the top cover plate 31, and are integrally formed. The integral formation of the top cover plate 31, the first insert plate 32, and the second insert plate 33 ensures the structural integrity and strength of the clamping half-cover 3, effectively clamping the outer frame shell 11 and the connecting steel plate 2. Simultaneously, the top cover plate 31 provides protection for the upper and lower ends of the FPR hollow plate 1. A threaded half-pipe 321 is vertically mounted on the middle of the outer side surface of the first insert plate 32, and the threaded half-pipe 321 is fixedly connected to the first insert plate 32. The threaded half-tube 321 on the outer surface of the first insert plate 32 provides an installation base for the subsequent installation of the locking bolt 34. After the two sets of first insert plates 32 are assembled together, the two sets of opposing threaded half-tubes 321 can form a threaded tube, facilitating the installation of the locking bolt 34 and enabling further locking of the clamping half-cover 3. A matching locking bolt 34 is installed in the threaded half-tube 321, and the head of the locking bolt 34 is provided with an operating lever cap 341. The locking bolt 34 and the operating lever cap 341 are integrally formed. The locking bolt 34 cooperates with the threaded half-tube 321, and the operating lever cap 341 allows for easy tightening or loosening of the locking bolt 34, further enhancing the connection stability between the clamping half-cover 3 and the outer frame shell 11 and the connecting steel plate 2. The upper end face of the top cover plate 31 has a top groove 311 for accommodating the operating lever cap 341. The top groove 311 on the top cover plate 31 can accommodate the operating rod cap 341, making the surface of the retaining wall smoother and preventing the operating rod cap 341 from protruding and affecting the appearance and use of the retaining wall.

[0029] In this embodiment, during actual installation, the FPR hollow plate 1 and the connecting steel plate 2 are arranged alternately to initially engage with each other. The clamping half-cap 3 is installed at both ends of the outer frame shell 11, clamping it between the outer frame shell 11 and the connecting steel plate 2, ensuring a tight engagement. The locking bolt 34 is installed in the threaded half-pipe 321, and tightened using the operating rod cap 341 to further enhance connection stability. The operating rod cap 341 is checked to ensure it is fully retracted into the top groove 311, ensuring the retaining wall surface is flat. The connection points of the retaining wall need to be inspected periodically to check for loose locking bolts 34; if loose, they should be tightened promptly. The FPR hollow plate 1 and the connecting steel plate 2 should be checked for damage or corrosion; if any are found, they should be repaired or replaced promptly.

[0030] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
