AI Technical Summary

Problems solved by technology

Steel components have high bearing capacity and good impact resistance. Under the same load, they are generally lighter than reinforced concrete components. The connection method is simple and convenient for construction and installation. However, due to the material characteristics of steel components, their corrosion resistance and fire resistance are poor, and special treatment is required. Use, and frequent maintenance during the use period, high engineering costs and maintenance costs during the use period
Reinforced concrete components have good bearing capacity, simple manufacture, wide range of materials, easy to master technology, low cost, and are widely used; however, the strength of concrete itself is low, the impact resistance is poor, and high-strength concrete is easy to crack; at the same time, steel bars need to be anti-corrosion Protection, reinforced concrete components are bulky, inconvenient to transport and install, and difficult to construct; and reinforced concrete components often appear missing corners and cracks after installation, which seriously affect the bearing capacity and durability of the components, making the components unable to reach the design service life. Long-term maintenance workload is heavy and maintenance costs are high
In addition to the above two components, there are also some composite material components, which are generally combined with steel, cement-based materials, and high polymer resin materials, but the problems of the above components have not been avoided; at the same time, when high polymer resin materials are used , there is also the problem of organic matter aging under different environmental conditions, so it still cannot reach the designed service life

Abstract

The invention relates to a three-dimensional fiber web composite plate structure which comprises a three-dimensional fiber net body and a filling material, wherein the three-dimensional fiber net bodyis prepared from a non-metal three-dimensional fiber net, and the filling material is filled into gaps in the three-dimensional fiber net body. Compared with the prior art, the invention discloses the three-dimensional fiber net composite plate structure; compared with existing steel members and reinforced concrete members, the three-dimensional fiber net composite plate structure disclosed by the technical scheme has light weight and corrosion resistance; as the filling material is filled into the three-dimensional fiber net body, the three-dimensional fiber net body can bear tensile stress;furthermore, the three-dimensional fiber net composite plate structure is prepared from a non-metal material and has certain toughness, and bearing capacity is further improved; compared with composite plates prepared from steel and cement based materials and a high polymer resin material, the three-dimensional fiber net composite plate structure is not prone to be affected by external environment and be damaged too early, and the service life of the three-dimensional fiber net composite plate structure is prolonged.
