Description

Technical Field

[0001] This utility model relates to the field of fiberglass grating technology, and in particular to a heavy-duty fiberglass grating. Background Technology

[0002] Fiberglass grating is a plate-like material with many openings, made of fiberglass as reinforcement and unsaturated polyester resin as matrix, through a special processing and composite process. Fiberglass grating can be used as a structural material for floors, trench covers, platforms, ship decks, stairs, walkways, etc., in corrosive environments. It features corrosion resistance, flame retardancy, non-magnetic insulation, bright colors, and a variety of styles and forms to choose from.

[0003] The existing new type of fiberglass grating (publication number: CN218234162U) has at least the following drawbacks: Although the device enhances the overall strength of the fiberglass grating through the setting of cross-shaped frame, rectangular frame and core plate, the cross-shaped frame and rectangular frame need to span the grid, which will block the grid holes. When the fiberglass grating needs to be used in the drainage mechanism, the blocked grid holes will block the drainage, resulting in insufficient applicability of the device. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a heavy-duty fiberglass grating.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heavy-duty fiberglass grating includes a fiberglass grating body, which is composed of an upper structural layer, a middle structural layer and a lower structural layer. Each of the upper, middle and lower structural layers consists of an outer reinforcing frame, a mesh and a central reinforcing plate. The outer reinforcing frame, the mesh and the central reinforcing plate are all made of fiberglass and are integrally formed.

[0007] As a further embodiment of this utility model, the middle structural layer is formed by casting a mold between the upper and lower structural layers.

[0008] As a further embodiment of this utility model, the upper structural layer and the lower structural layer have the same thickness, and the middle structural layer has a thickness that is one-quarter of the thickness of the upper structural layer and the lower structural layer.

[0009] As a further embodiment of this utility model, the central reinforcing plate is located at the center of the grid, and the area of ​​the central reinforcing plate is exactly the area of ​​four grid cells.

[0010] As a further embodiment of this invention, the thickness of the outer reinforcing frame is twice the thickness of the mesh.

[0011] As a further embodiment of this utility model, L-shaped plates are adhered and fixed to all four sides of the outer wall of the fiberglass grating body, and two mounting holes are opened on the top surface of the L-shaped plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By adding an uncured middle structural layer solution between two fully cured upper and lower structural layers, the upper, middle, and lower structural layers form a whole after the middle structural layer cures, making the fiberglass grating body a multi-layer structure. This multi-layer structure can more effectively distribute external loads, improve the overall load-bearing capacity, enhance the bending stiffness of the structure, and reduce deformation. At the same time, this reinforced structure will not obstruct or block the mesh, allowing the fiberglass grating body to be used in various drainage systems, increasing the applicability of the device.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-4 As shown, a heavy-duty fiberglass grating includes a fiberglass grating body 1, which is composed of an upper structural layer 101, a middle structural layer 102, and a lower structural layer 103. The upper structural layer 101, the middle structural layer 102, and the lower structural layer 103 are all composed of an outer reinforcing frame 1011, a mesh 1012, and a central reinforcing plate 1013. The outer reinforcing frame 1011, the mesh 1012, and the central reinforcing plate 1013 are all made of fiberglass and are integrally formed.

[0023] like Figures 2-4 As shown, in this embodiment, the intermediate structural layer 102 is formed by casting a mold between the upper structural layer 101 and the lower structural layer 103. By adding an uncured intermediate structural layer 102 liquid between the two fully cured upper structural layers 101 and lower structural layers 103, after the intermediate structural layer 102 is cured, the upper structural layer 101, intermediate structural layer 102 and lower structural layer 103 form a whole, making the fiberglass grating body 1 a multi-layer structure. This multi-layer structure can more effectively distribute external loads, improve the overall load-bearing capacity, enhance the bending stiffness of the structure, and reduce deformation. At the same time, this reinforced structure will not obstruct or block the mesh 1012, so that the fiberglass grating body 1 can be applied to various drainage mechanisms, increasing the applicability of the device.

[0024] like Figures 2-4As shown, in this embodiment, the upper structural layer 101 and the lower structural layer 103 have the same thickness, and the middle structural layer 102 has a thickness that is one-quarter of the thickness of the upper structural layer 101 and the lower structural layer 103. By setting the thickness of the middle structural layer 102 to be one-quarter of the thickness of the upper structural layer 101 and the lower structural layer 103, the middle structural layer 102 only acts as an adhesive layer to connect the upper structural layer 101, the middle structural layer 102 and the lower structural layer 103 to form a whole. This avoids the middle structural layer 102 being too thick, which would cause the upper structural layer 101 and the mold to block it, making it difficult to dry and cure quickly during production.

[0025] like Figures 2-4 As shown, in this embodiment, the central reinforcing plate 1013 is located at the center of the grid 1012, and the area of ​​the central reinforcing plate 1013 is exactly the area of ​​four grids of the grid 1012. By setting the central reinforcing plate 1013, the central compressive strength of the fiberglass grating body 1 can be increased.

[0026] like Figures 2-4 As shown, in this embodiment, the thickness of the outer reinforcing frame 1011 is twice the thickness of the mesh 1012. By setting the thickness of the outer reinforcing frame 1011 to be twice the thickness of the mesh 1012, the strength and load-bearing capacity of the outer reinforcing frame 1011 are guaranteed.

[0027] like Figures 2-4 As shown in this embodiment, L-shaped plates 2 are glued and fixed to all four sides of the outer wall of the fiberglass grating body 1. Two mounting holes 201 are opened on the top surface of the L-shaped plates 2. The installation of the fiberglass grating body 1 is facilitated by setting the L-shaped plates 2 and the mounting holes 201.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, by adding an uncured middle structural layer 102 liquid between the two fully cured upper structural layers 101 and the lower structural layer 103, after the middle structural layer 102 cures, the upper structural layer 101, the middle structural layer 102, and the lower structural layer 103 form a whole, making the fiberglass grating body 1 a multi-layer structure. This multi-layer structure can more effectively distribute external loads, improve the overall load-bearing capacity, enhance the bending stiffness of the structure, and reduce deformation. At the same time, this reinforced structure will not obstruct or block the mesh 1012, allowing the fiberglass grating body 1 to be applied to various drainage mechanisms, increasing the device's efficiency. For applicability, by setting the thickness of the middle structural layer 102 to one-quarter of the thickness of the upper structural layer 101 and the lower structural layer 103, the middle structural layer 102 serves only as an adhesive layer to connect the upper structural layer 101, the middle structural layer 102, and the lower structural layer 103 to form a whole. This avoids the middle structural layer 102 being too thick, which would obstruct the upper structural layer 101 and the mold, making it difficult to dry and cure quickly during production. The central reinforcing plate 1013 can increase the central compressive strength of the fiberglass grating body 1. The outer reinforcing frame 1011 is twice the thickness of the mesh 1012, ensuring the strength and load-bearing capacity of the outer reinforcing frame 1011. The L-shaped plate 2 and the mounting hole 201 facilitate the installation of the fiberglass grating body 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
