Abstract

The invention discloses a box structure based on a steel plate with holes and a preparation method thereof, comprising: a box body, the box body includes: a steel plate with holes forming the shape of the box, and a steel plate with holes arranged outside the steel plate with holes The protective layer is a filling layer arranged in the steel plate with holes and connected with the protective layer, and a fireproof crack control layer arranged inside the steel plate with holes and connected with the filling layer. The box structure in this embodiment uses box-shaped perforated steel plates to connect the protective layer, filling layer, and fire prevention and crack control layer, which ensures the bearing capacity and integrity of the box structure, and realizes the connection between different material layers. Working together, so that the box structure has good durable protection performance, greatly improving the service life of the box structure.

Description

technical field [0001] The invention relates to the technical field of concrete materials, in particular to a box structure based on perforated steel plates and a preparation method thereof. Background technique [0002] At present, the construction of super-large urban agglomerations has gradually entered the fast lane 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. Take the underground integrated pipe gallery as an example. At present, most of the urban engineering pipelines are buried in the underground integrated pipe gallery to save the urban space above ground. At present, the construction of marine infrastructure such as sea-crossing bridges...
