Description

Technical Field

[0001] This utility model relates to the field of fiberglass grating technology, and more specifically, to a high-toughness composite fiberglass grating with reinforcing ribs. Background Technology

[0002] Fiberglass grating, also known as fiberglass grating, is a plate-shaped material with many openings made of fiberglass as reinforcing material and through special processing. Fiberglass grating can be used as a structural material for floors, trench covers, platforms, stairs, etc. in corrosive environments, as well as for road flower bed railings, fences, etc.

[0003] A search revealed that patent publication number CN220488188U discloses an anti-collision fiberglass grating. It includes an outer frame and two fiberglass grating bodies. An inner groove is formed inside the outer frame, with fiberglass grating bodies movably connected to both ends of the groove. The two fiberglass grating bodies are connected by a buffer assembly. A replacement assembly is located at the top of the outer frame to assist in replacing the buffer assembly. By utilizing the inner groove inside the outer frame, the two fiberglass grating bodies can slide at their respective ends. The buffer assembly located between the two fiberglass grating bodies buffers the impact force on their surfaces. The replacement assembly at the top of the outer frame allows for replacement of the buffer assembly located inside the inner groove, thereby improving the impact buffering effect on the fiberglass grating bodies to a certain extent. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Due to its open mesh, existing fiberglass gratings in applications such as sewage treatment, municipal pipe networks, and landscaping allow large particles of debris to enter below the grating with the flow of water or wind. This leads to the accumulation of large particles inside the grating, which is difficult to clean, easily breeds mosquitoes, emits odors, and even creates unsanitary corners. Furthermore, relying on the frame and horizontal and vertical ribs for support, when bearing heavy loads such as vehicles running over or equipment being piled up, the load is concentrated in a local area, which can easily cause the grating to deform and crack. In emergency situations, when the grating needs to be quickly laid as a ground hardening layer, it requires repeated adjustments and alignment. When under stress, gaps will appear between adjacent grating panels, increasing assembly time and load-bearing stability.

[0005] Therefore, a high-toughness composite fiberglass grating with reinforcing ribs is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-toughness composite fiberglass grating with reinforcing ribs to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-toughness composite fiberglass grating with reinforcing ribs, comprising a central reinforcing layer, an outer frame reinforcing rib, a cross reinforcing rib, and a metal mesh plate. Fiberglass layers are provided on both the upper and lower end faces of the central reinforcing layer. The outer frame reinforcing rib is embedded in the inner cavity of the central reinforcing layer and the outer periphery of the fiberglass layer. The cross reinforcing rib is embedded at the center of the central reinforcing layer and the fiberglass layer.

[0008] The fiberglass layer has longitudinal mounting grooves on both sides of its front end, longitudinal limiting blocks on both sides of its rear end, transverse mounting grooves on both ends of its right side, and transverse limiting blocks on both sides of its left side. A surrounding frame is installed on the upper end of the outer frame reinforcing rib, and the metal mesh plate is welded to the inner surface of the surrounding frame.

[0009] Preferably, the outer frame reinforcing ribs and the cross reinforcing ribs are welded together, and the outer frame reinforcing ribs and the cross reinforcing ribs form a grid-like structure.

[0010] Preferably, the two sets of longitudinal limiting blocks correspond to the two sets of longitudinal mounting slots, and the two sets of transverse limiting blocks correspond to the two sets of transverse mounting slots.

[0011] Preferably, the metal mesh panel has a plurality of equally spaced circular holes, and mounting posts are provided at the four corners of the bottom of the surrounding frame.

[0012] Preferably, limit holes are provided at the four corners of the outer frame reinforcing ribs, and the four sets of limit holes correspond to the four sets of mounting columns respectively.

[0013] Preferably, the surrounding frame abuts against the upper end face of the outer frame reinforcing rib, and the surrounding frame is limited by the four sets of mounting posts respectively embedded in the inner cavity of the four sets of limiting holes.

[0014] Preferably, both the central reinforcing layer and the fiberglass layer have square holes in their inner cavities, and there are several groups of square holes, which are distributed at equal intervals.

[0015] Preferably, the bottom surface of one group of the fiberglass layers is provided with strip-shaped anti-slip patterns, with a pattern depth and spacing of 1.2 mm and 15 mm, respectively.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with existing technologies, this high-toughness composite fiberglass grating with reinforcing ribs allows for flexible switching between mesh and grating modes through a rapidly switchable metal mesh panel. In scenarios requiring ventilation, light transmission, drainage, or filtration, the mesh mode is used, where the round hole structure of the metal mesh panel can block large particles of debris, maintaining good water permeability and ventilation. When heavy loads need to be supported and surface flatness needs to be enhanced, the grating mode is switched to fully utilize the high strength characteristics of the grating body.

[0018] 2. Compared with existing technologies, this high-toughness composite fiberglass grating with reinforcing ribs forms a grid-like structure by welding the outer frame reinforcing ribs and cross reinforcing ribs together. Combined with the tenon and mortise nesting installation method of the limiting blocks and installation grooves, it can withstand greater weight and evenly distribute the load to various parts. It also realizes tool-free quick docking of grating panels, making it suitable for rapid construction in emergency projects. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] As attached Figures 1 to 4The high-toughness composite fiberglass grating with reinforcing ribs shown includes a central reinforcing layer 1, outer frame reinforcing ribs 3, cross reinforcing ribs 4, and a metal mesh plate 12. Fiberglass layers 2 are provided on both the upper and lower ends of the central reinforcing layer 1. The central reinforcing layer 1 is made of a blend of glass fiber and aramid fiber and bears the main load transfer function. The upper and lower ends of the central reinforcing layer 1 are tightly bonded to the fiberglass layers 2 to form a sandwich structure, balancing the stress distribution between the inner and outer layers and avoiding cracking caused by stress concentration in a single material. The outer frame reinforcing ribs 3 are embedded in the inner cavity of the outer periphery of the central reinforcing layer 1 and the fiberglass layers 2, forming a closed frame and enhancing the tensile strength of the grating edges. The cross reinforcing ribs 4 are embedded at the center of the central reinforcing layer 1 and the fiberglass layers 2. The cross reinforcing ribs 4 are arranged perpendicularly and intersectingly at the center of the grating, forming a grid-shaped support network with the outer frame reinforcing ribs 3. Stress can be evenly transmitted to the surrounding area through the grid structure.

[0026] Both sides of the front end of the fiberglass layer 2 are provided with longitudinal mounting grooves 6, and both sides of the rear end of the fiberglass layer 2 are provided with longitudinal limiting blocks 5. The opposite faces of two sets of adjacent fiberglass gratings can be embedded in the inner cavity of the longitudinal mounting grooves 6 through the longitudinal limiting blocks 5, thereby limiting the two sets of fiberglass gratings. Both ends of the right side of the fiberglass layer 2 are provided with transverse mounting grooves 7, and both sides of the left side of the fiberglass layer 2 are provided with transverse limiting blocks 8. The transverse limiting block 8 of one set of fiberglass gratings is embedded in the transverse mounting groove 7 of the other set of fiberglass gratings for limiting. The upper end of the outer frame reinforcing rib 3 is provided with a surrounding frame 11, and the metal mesh plate 12 is welded to the inner surface of the surrounding frame 11. The surrounding frame 11 enhances the strength of the edge of the metal mesh plate 12, and the metal mesh plate 12 can block the upper end face of the fiberglass layer 2. Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0028] In a preferred embodiment, the outer frame reinforcing rib 3 and the cross reinforcing rib 4 are welded together, and the outer frame reinforcing rib 3 and the cross reinforcing rib 4 form a grid-shaped structure. The outer frame reinforcing rib 3 serves as the overall frame and forms a rigid support for the grid-shaped structure with the welding joint of the cross reinforcing rib 4.

[0029] In a preferred embodiment, the two sets of longitudinal limiting blocks 5 correspond to the two sets of longitudinal mounting grooves 6 respectively, and the two sets of transverse limiting blocks 8 correspond to the two sets of transverse mounting grooves 7 respectively. The tenon-and-mortise joint between the longitudinal limiting blocks 5, the transverse limiting blocks 8 and the longitudinal mounting grooves 6 and the transverse mounting grooves 7 can realize the plug-and-play installation between multiple sets of grid panels.

[0030] In a preferred embodiment, the metal mesh plate 12 has several equally spaced circular holes on its surface. The metal mesh plate 12 filters large particles of impurities, preventing debris from entering the interior of the grid. Mounting posts 13 are provided at the four corners of the bottom of the surrounding frame 11, and limiting holes 10 are provided at the four corners of the outer frame reinforcing rib 3. The four sets of limiting holes 10 correspond to the four sets of mounting posts 13 respectively. The surrounding frame 11 abuts against the upper end face of the outer frame reinforcing rib 3. The surrounding frame 11 is limited by the four sets of mounting posts 13 being embedded into the inner cavity of the four sets of limiting holes 10 respectively. The mounting posts 13 at the bottom of the surrounding frame 11 are embedded into the limiting holes 10 of the outer frame reinforcing rib 3 to achieve tight abutment installation. The surrounding frame 11 and the metal mesh plate 12 can be directly installed on the outer frame reinforcing rib 3, and the switching between the two modes of baffle and grid can be quickly realized.

[0031] In a preferred embodiment, both the central reinforcing layer 1 and the fiberglass layer 2 have square holes 9 inside. Several sets of square holes 9 are provided, and the sets of square holes 9 are distributed at equal intervals. The sets of square holes 9 are the main holes of the fiberglass grating. Through a simple geometric grid, multiple objectives of strength, weight and function are optimized.

[0032] In a preferred embodiment, the bottom surface of one set of fiberglass layers 2 is provided with strip-shaped anti-slip patterns, with a pattern depth and spacing of 1.2mm and 15mm respectively. The strip-shaped anti-slip patterns with a depth of 1.2mm and a spacing of 15mm enhance the friction with the contact surface and prevent slippage.

[0033] The working process of this utility model is as follows: First, the central reinforcing layer 1 bears the main load. It is made of a blend of glass fiber and aramid fiber. With the high strength fiber characteristics, it transmits the loads such as gravity and pressure downwards. The fiberglass layers 2 on the upper and lower ends form a sandwich structure with the central reinforcing layer 1. During the load transmission process, the three work together. The fiberglass layer 2 can buffer and disperse stress, avoiding the concentration of force on the central reinforcing layer 1. The outer frame reinforcing ribs 3 are embedded in the inner cavity of the outer periphery of the central reinforcing layer 1 and the fiberglass layer 2, forming a closed frame.

[0034] When the edge of the grid is subjected to external forces such as pulling or impact, the outer frame reinforcing rib 3 can directly resist and distribute the force to the entire grid structure. The cross reinforcing rib 4 is arranged vertically in the center of the grid and welded with the outer frame reinforcing rib 3 to form a grid-shaped structure. When the central area bears a load, the cross reinforcing rib 4 will transfer the force to the outer frame reinforcing rib 3, and then transmit it to the surrounding area through the outer frame reinforcing rib 3, so as to achieve uniform stress distribution.

[0035] During the installation of the grid, align the longitudinal limiting block 5 of one set of grids with the longitudinal mounting groove 6 of another set of grids, and align the transverse limiting block 8 with the transverse mounting groove 7. Then, forcefully insert the grids to complete the limiting and fixing of the two sets of grids, quickly forming a large area of ​​grid installation. During use, if it is necessary to filter debris, the metal mesh plate 12 will function by means of the equally spaced round holes on its surface, and large particles of impurities will be blocked above the grid.

[0036] When it is necessary to switch to baffle mode or to clean and replace the metal mesh plate 12, the mounting post 13 at the bottom of the surrounding frame 11 can be pulled out from the limiting hole 10 of the outer frame reinforcing rib 3, and the surrounding frame 11 and metal mesh plate 12 can be removed. The square holes 9 in the inner cavity of the central reinforcing layer 1 and the fiberglass layer 2 reduce the weight of the grating without affecting the overall strength, and also facilitate ventilation and drainage. The strip anti-slip texture with a depth of 1.2mm and a spacing of 15mm at the bottom of the fiberglass layer 2 increases the surface friction and prevents slippage. The above is the working principle of this high-toughness composite fiberglass grating with reinforcing ribs.
