Abstract
Description
Technical Field
[0001] This utility model relates to the field of grating technology, specifically a fiberglass grating for tree greening. Background Technology
[0002] Fiberglass reinforced plastic (FRP) grating, also known as fiberglass grating, is a type of plate-like material with many open spaces, made of fiberglass as reinforcement and unsaturated polyester resin as the matrix, through a special processing and composite process. FRP grating can be used as a structural material for flooring in corrosive environments, trench covers, platforms, ship decks, stairs, walkways, etc. It features corrosion resistance, flame retardancy, non-magnetic insulation, bright colors, and a variety of styles and forms to choose from.
[0003] Currently, trees are planted along both sides of urban roads, and their roots are protected by surrounding blocks. To better protect the trees, fiberglass grating is sometimes laid inside the perimeter of each tree block. This fiberglass grating used for tree greening is made by splicing two half-grids together. Currently, the two half-grids are made by cutting a whole fiberglass grating and then making an arc-shaped hole in the middle to fit the tree. However, this direct laying method makes it very easy for the two half-grids to separate when the soil is soft or arched, or when someone accidentally steps on the grating. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content
[0004] The purpose of this utility model is to provide a fiberglass grating for tree greening, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a fiberglass grating for tree greening, comprising a first half-grating and a second half-grating;
[0006] A first semi-circular arc plate is provided at the center of one side of the first half-grid, and a first slot is provided on the outer surface of both ends of the first semi-circular arc plate. Several first extension plates are provided on one side of the first semi-circular arc plate of the first half-grid.
[0007] A second semi-circular arc plate is provided at the center of one side of the second half-grid. The inner surfaces of both ends of the second semi-circular arc plate are provided with second slots. Several second extension plates are provided on one side of the second half-grid. The second half-grid and the first half-grid are spliced together by two screws and several nuts. The two ends of the second semi-circular arc plate are engaged with the first slots at the two ends of the first semi-circular arc plate. The two ends of the first semi-circular arc plate are engaged with the second slots at the two ends of the second semi-circular arc plate. The first extension plate and the second extension plate correspond one to one and are tightly connected.
[0008] The two screws pass outward from the first slot of the first semi-circular arc plate, through the second semi-circular arc plate, each of the first extension plates and the second extension plate, respectively. The nuts cooperate with the screws, and the nuts are in pairs. The two nuts in the same pair are pressed against the outer sides of the mutually mating first extension plates and second extension plates.
[0009] Preferably, the present invention provides a fiberglass grating for tree greening, wherein the first semi-circular arc plate is located at the first slot, the second semi-circular arc plate is located at the second slot, and both the first extension plate and the second extension plate are provided with through holes, through which the screw passes.
[0010] Preferably, the fiberglass grating for tree greening provided by this utility model has the same height for the first half-grating, the second half-grating, the first semi-circular arc plate, the second semi-circular arc plate, the first extension plate, and the second extension plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The first half of the grid has a first semi-circular arc plate and several first extension plates on one side, and the second half of the grid has a second semi-circular arc plate and several second extension plates on one side. The first and second semi-circular arc plates cooperate with each other, and the first and second extension plates correspond and cooperate one-to-one. They are secured together on both sides by a screw and several nuts. The main body is assembled from the first and second half of the grid using screws and nuts. When laid in the planting area, even if the soil loosens due to rain or people step on the grid, the first and second half of the grid will not easily separate, greatly improving the connection performance between the two grids. Furthermore, the first and second semi-circular arc plates significantly improve the structural strength of the first and second half of the grid itself. Attached Figure Description

[0026] Usage and principle: Glass fiber is used as the reinforcing material and unsaturated polyester resin is used as the matrix. The mixture is used as the raw material and the first half grid 1 and the second half grid 5 are obtained by compression molding. The first half grid 1 has a first semi-circular arc plate 2 and several first extension plates 4 reserved on the connecting side. The second half grid 5 has a second semi-circular arc plate 6 and several second extension plates 8 reserved on the connecting side. In use, the first half-grid 1 and the second half-grid 5 are placed on both sides of the tree and then spliced together, so that the first slot 3 of the first semi-circular arc plate 2 is inserted into the two ends of the second semi-circular arc plate 6. At this time, the two ends of the first semi-circular arc plate 2 are exactly engaged with the second slot 7 of the second semi-circular arc plate 6. At the same time, the first extension plate 4 and the second extension plate 8 cooperate with each other. Two screws 9 are passed outward from the two ends of the first semi-circular arc plate 2 through the second semi-circular arc plate 6, the first extension plate 4, and the second extension plate 8 respectively. When passing through each of the first extension plates 4 and the second extension plate 8, nuts 10 are connected to the screws 9, so that there is a nut 10 on each side of the two cooperating first extension plates 4 and the second extension plate 8. After tightening each nut 10, the assembly of the first half-grid 1 and the second half-grid 5 is completed. Then, the first half-grid 1 and the second half-grid 5 are placed at the base of the tree and cooperate with the brickwork around the planting area to complete the protection of the tree planting area.

They are fastened together on both sides by a screw 9 and several nuts 10. The main body is assembled from the first half-grid 1 and the second half-grid 5 by screws 9 and nuts 10. When laid in the planting area of trees, even if the soil is loosened by rain or people step on the grid, the first half-grid 1 and the second half-grid 5 will not easily separate, which greatly improves the connection performance between the two grids. Furthermore, the first semi-circular arc plate 2 and the second semi-circular arc plate 6 greatly improve the structural strength of the first half-grid 1 and the second half-grid 5 themselves.
