Embodiment 1

[0039] The invention discloses a box structure based on FRP grid, please refer to figure 1 and figure 2 . The box structure based on the FRP grid (hereinafter referred to as the box structure) includes: a box body, and the box body includes: an FRP grid forming a box shape, and a protective layer arranged on the outside of the FRP grid 100, a filling layer 200 arranged in the FRP grid and connected to the protection layer 100, and a fireproof crack control layer 300 arranged inside the FRP grid and connected to the filling layer 200.

[0040]In the embodiment of the present invention, the box body may be a quadrangular box or a polygonal box, it should be understood that the present invention is not limited thereto. Wherein, the FRP (fiber reinforced composite material, Fiber Reinforced Polymer, or Fiber Reinforced Plastic, FRP for short) grid is made of reinforced fiber materials, such as glass fiber, carbon fiber, aramid fiber, etc., and the base material is wound, molded...

Embodiment 2

[0057] On the basis of the box structure based on the above-mentioned FRP grid, the present invention also discloses a preparation method of the box structure based on the FRP grid. Specifically, please refer to image 3 , the preparation method comprises:

[0058] S100, fixing the box-shaped FRP grid inside the template 10;

[0059] S200, fixing the filling body 20 in the first accommodation chamber 210;

[0060] S300, pouring a protective layer 100 outside the FRP grid;

[0061] S400, pouring the fire prevention crack control layer 300 in the second accommodation chamber 310;

[0062] S500, removing the filling body 20, and pouring the filling layer 200 in the first accommodation cavity 210;

[0063] In the embodiment of the present invention, please refer to Figure 4 to Figure 8 . Before the manufacturing process of the box structure, first connect a plurality of third grid boxes 600 between the first grid box 400 and the second grid box 500, and set a plurality of fi...

Abstract

The invention discloses a box structure based on an FRP grid and a preparation method thereof. The box structure comprises a box body, wherein the box body comprises the FRP grid forming a box shape,a protective layer arranged on the outer side of the FRP grid, a filling layer arranged in the FRP grid and connected with the protective layer, and a fireproof crack control layer arranged on the inner side of the FRP grid and connected with the filling layer. According to the box structure, the protective layer, the filling layer and the fireproof crack control layer are connected through the FRP grid in the box shape, the bearing capacity and integrity of the box structure are guaranteed, and joint work of different material layers is achieved, so that the box structure has good durable protective performance, and the service life of the box structure is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of concrete materials, in particular to an FRP grid-based box structure and a preparation method thereof. Background technique [0002] At present, the construction of super-large urban agglomerations has gradually entered the fast lane along with the urbanization process. In this process, the constraints and limitations of urban ground space have become prominent. The development and utilization of underground space has become a key link in the construction and development of urban agglomerations, and underground infrastructure is an important carrier for the development and utilization of urban underground space. Taking the underground comprehensive pipe gallery as an example, most of the urban engineering pipelines are buried in the underground comprehensive pipe gallery to save the above-ground space in the city. At present, the construction of marine infrastructure such as cross-sea bridges, submarine ...
